Description

アウトリガ装置Outrigger device
　本発明は、アウトリガ装置に関する。さらに詳しくは、本発明は、たとえば、積載型トラッククレーンにおける格納時に縦アウトリガを上方に配置できるアウトリガ装置に関する。 The present invention relates to an outrigger device. More specifically, the present invention relates to an outrigger device in which a vertical outrigger can be disposed upward during storage in a load-type truck crane, for example.
　図１０に示すように、積載形トラッククレーン１００は、汎用トラック１１０の運転室１１１と荷台１１２との間の車両フレーム１１３に小型クレーン１２０が搭載されたものである。小型クレーン１２０は、車両フレーム１１３上に固定されたベース１２１上に設けられている。このようなベース１２１には、アウトリガ装置１２２が取付けられている。 As shown in FIG. 10, the loading-type truck crane 100 includes a small crane 120 mounted on a vehicle frame 113 between a cab 111 and a loading platform 112 of a general-purpose truck 110. The small crane 120 is provided on a base 121 fixed on the vehicle frame 113. An outrigger device 122 is attached to such a base 121.
　一般に、アウトリガ装置１２２は、ベース１２１に横向きに固定された横アウトリガ１２３と、横アウトリガ１２３の先端に縦向きに固定された縦アウトリガ１２４とで構成されている。縦アウトリガ１２４は、下端にフロートを有する。このようなアウトリガ装置１２２は、作業開始時（アウトリガ装置の使用状態ともいう。）において、横アウトリガ１２３を張り出すとともに、縦アウトリガ１２４を伸長することにより、上記フロートを接地させる。これにより、積載形トラッククレーン１００の安定が確保される。また、アウトリガ装置１２２は、作業終了時（アウトリガ装置の格納状態ともいう。）において、縦アウトリガ１２４を収縮するとともに、横アウトリガ１２３を引き込んで、アウトリガ装置１２２を格納する。このような格納状態におけるアウトリガ装置の横幅寸法は、走行中の安全確保上、車両の幅寸法を越えることはできない。 Generally, the outrigger device 122 includes a horizontal outrigger 123 fixed to the base 121 in the horizontal direction and a vertical outrigger 124 fixed in the vertical direction to the tip of the horizontal outrigger 123. The vertical outrigger 124 has a float at the lower end. Such an outrigger device 122 projects the lateral outrigger 123 and extends the vertical outrigger 124 at the start of work (also referred to as the outrigger device in use), thereby grounding the float. Thereby, the stability of the loadable truck crane 100 is ensured. Further, the outrigger device 122 retracts the vertical outrigger 124 and retracts the horizontal outrigger 123 to store the outrigger device 122 at the end of the work (also referred to as a stored state of the outrigger device). The lateral width dimension of the outrigger device in such a storage state cannot exceed the width dimension of the vehicle for ensuring safety during traveling.
　特許文献１には、格納状態において、トラックの補機類や燃料タンクと、縦アウトリガとの干渉を防止できるアウトリガ装置の構造が開示されている。このような特許文献１に開示された構造の場合、縦アウトリガの基端部（使用状態における上端部）に設けられたボスが、横アウトリガの側端（車幅方向における外側の端部）に設けられた軸受により回転可能に支承されている。このような縦アウトリガは、上記ボスを中心に回転することにより、先端部（使用状態における下端部）が上方を向いた状態で格納される。 Patent Document 1 discloses a structure of an outrigger device that can prevent interference between a truck auxiliary device or a fuel tank and a vertical outrigger in a retracted state. In the case of the structure disclosed in Patent Document 1, the boss provided at the base end portion (upper end portion in the use state) of the vertical outrigger is provided at the side end (outer end portion in the vehicle width direction) of the lateral outrigger. It is rotatably supported by a provided bearing. Such a vertical outrigger is stored with the tip (the lower end in use) facing upward by rotating about the boss.
　ところで、上述のような従来技術の場合、格納状態において、縦アウトリガの車幅方向における外端面を車両の最大幅員内に収めるためには、横アウトリガの側端位置が、縦アウトリガの車幅方向における寸法分だけ車幅方向における内側に位置する必要がある。このため、横アウトリガの車幅方向における長さが短くなってしまい、使用状態において、アウトリガ装置の張出し幅を大きくできない。この結果、特許文献１に開示された従来技術は、クレーンの作業安定性の向上に限界があった。 By the way, in the case of the prior art as described above, in the retracted state, in order to fit the outer end surface in the vehicle width direction of the vertical outrigger within the maximum width of the vehicle, the side end position of the horizontal outrigger is in the vehicle width direction of the vertical outrigger. It is necessary to be located on the inner side in the vehicle width direction by the dimension of. For this reason, the length of the lateral outrigger in the vehicle width direction is shortened, and the overhanging width of the outrigger device cannot be increased in use. As a result, the prior art disclosed in Patent Document 1 has a limit in improving the work stability of the crane.
　また、特許文献２には、伸縮式の横アウトリガの横ビーム内箱と、横ビーム内箱の先端部の側面（トラック車体の前後方向における前面または後面の側壁）に回転可能に取り付けられた縦アウトリガとを有するアウトリガ装置が開示されている。その他、アウトリガ装置に関する従来技術として特許文献３に開示された構造が知られている。特許文献２および特許文献３に開示された構造の場合も、使用状態におけるアウトリガ装置の張出し幅を大きくすることに限界があった。 Further, Patent Document 2 discloses a longitudinal beam inner box of a telescopic lateral outrigger and a longitudinally attached to the side surface (front or rear side wall in the front-rear direction of the truck body) of the front end of the lateral beam inner box. An outrigger device having an outrigger is disclosed. In addition, a structure disclosed in Patent Document 3 is known as a conventional technique related to an outrigger device. In the case of the structures disclosed in Patent Document 2 and Patent Document 3, there is a limit to increasing the outrigger width of the outrigger device in use.

（アウトリガ装置１の基本構造について）
　図１および図２に示すように、本発明の第１実施形態に係るアウトリガ装置１は、積載形トラッククレーンに積載される小型クレーンに搭載される。小型クレーンは、ベースｂを有する。ベースｂは、トラックの車両フレーム１１３（図１０参照）に固定される。 (First embodiment)
Next, an outrigger device according to a first embodiment of the present invention will be described with reference to the drawings.
(Basic structure of outrigger device 1)
As shown in FIGS. 1 and 2, the outrigger device 1 according to the first embodiment of the present invention is mounted on a small crane loaded on a load-type truck crane. The small crane has a base b. The base b is fixed to the vehicle frame 113 (see FIG. 10) of the truck.
　そして、ベースｂには、左右一対のアウトリガ装置１（前側アウトリガおよび後側アウトリガともいう。）が固定される。アウトリガ装置１は、左右勝手違い（換言すれば、車幅方向において対称）に構成される。なお、以下のアウトリガ装置１およびアウトリガ装置１を構成する各部材の説明において、特に断ることなく「車幅方向」、「前後方向」、および「上下方向」といった場合には、アウトリガ装置１を車両（たとえば、図１０のトラック１１０）に組み付けた状態における車両の各方向をいう。図１および図２に示す直交座標系（Ｘ，Ｙ，Ｚ）において、前後方向はＸ方向に、車幅方向はＹ方向に、上下方向はＺ方向に、それぞれ対応する。図１および図２において、Ｘ方向＋側が前方である。 And a pair of left and right outrigger devices 1 (also referred to as a front outrigger and a rear outrigger) are fixed to the base b. The outrigger device 1 is configured to be different from side to side (in other words, symmetrical in the vehicle width direction). In the following description of the outrigger device 1 and each member constituting the outrigger device 1, the “outer trigger device 1 is referred to as a vehicle in the case of“ vehicle width direction ”,“ front-rear direction ”, and“ vertical direction ”without particular notice. (For example, each direction of the vehicle in the state assembled | attached to the truck 110 of FIG. 10). In the orthogonal coordinate system (X, Y, Z) shown in FIGS. 1 and 2, the front-rear direction corresponds to the X direction, the vehicle width direction corresponds to the Y direction, and the vertical direction corresponds to the Z direction. 1 and 2, the X direction + side is the front.
　左右一対のアウトリガ装置１はそれぞれ、車両フレームの横方向（左右方向または車幅方向ともいう。）に延びるように設けられた一対の横アウトリガ１０と、各横アウトリガ１０の先端（車幅方向における外側の端部）にそれぞれ連結された一対の縦アウトリガ２０とを備える。 Each of the pair of left and right outrigger devices 1 includes a pair of lateral outriggers 10 provided so as to extend in a lateral direction of the vehicle frame (also referred to as a lateral direction or a vehicle width direction), and tips of the lateral outriggers 10 (in the vehicle width direction). A pair of vertical outriggers 20 respectively connected to the outer end portions).
　左右一対のアウトリガ装置１同士は、実質同一の構成である。このため、以下、アウトリガ装置１の構成については、一方（具体的には、前側）のアウトリガ装置１（前側アウトリガともいう。）を中心に説明する。他方（具体的には、後側）のアウトリガ装置１（後側アウトリガともいう。）については、適宜説明する。 The pair of left and right outrigger devices 1 have substantially the same configuration. Therefore, hereinafter, the configuration of the outrigger device 1 will be described focusing on one (specifically, the front side) outrigger device 1 (also referred to as a front side outrigger). The other (specifically, rear) outrigger device 1 (also referred to as a rear outrigger) will be described as appropriate.
　なお、左右一対のアウトリガ装置１同士は、前後方向において隣り合うように配置される。このような左右一対のアウトリガ装置１同士の配置態様については、後述する。以下の説明において、一対のアウトリガ装置1の横アウトリガ１０が伸長状態にあり、かつ、縦アウトリガ２０の先端（具体的には、フロート２３）が下方を向いた状態（接地可能な状態ともいう。）を、アウトリガ装置１の使用状態という（展開状態ともいう）。 It should be noted that the pair of left and right outrigger devices 1 are arranged adjacent to each other in the front-rear direction. The arrangement of the pair of left and right outrigger devices 1 will be described later. In the following description, the lateral outrigger 10 of the pair of outrigger devices 1 is in an extended state, and the front end (specifically, the float 23) of the vertical outrigger 20 faces downward (also referred to as a groundable state). ) Is referred to as a use state of the outrigger device 1 (also referred to as a developed state).
　一方、一対のアウトリガ装置１の横アウトリガ１０が収縮状態にあり、かつ、縦アウトリガ２０の先端が上方を向いた状態（図１および図２に示す状態）を、アウトリガ装置１の格納状態という。 On the other hand, the state in which the lateral outrigger 10 of the pair of outrigger devices 1 is in the contracted state and the front end of the vertical outrigger 20 faces upward (the state shown in FIGS. 1 and 2) is referred to as the retracted state of the outrigger device 1.
　横アウトリガ１０は、車幅方向に伸縮することにより、収縮状態と伸長状態との間を移行可能である（つまり、車幅方向に伸縮可能である。）。具体的には、横アウトリガ１０は、横ビーム外箱１１と、横ビーム内箱１２とを有する。横ビーム外箱１１は、先端部（車幅方向における外側の端部）に開口部を有する。横ビーム外箱１１は、車両フレーム１１３（図１０参照）に固定される。 The lateral outrigger 10 can move between a contracted state and an extended state by expanding and contracting in the vehicle width direction (that is, it can expand and contract in the vehicle width direction). Specifically, the lateral outrigger 10 includes a lateral beam outer box 11 and a lateral beam inner box 12. The lateral beam outer box 11 has an opening at the tip (the outer end in the vehicle width direction). The lateral beam outer box 11 is fixed to a vehicle frame 113 (see FIG. 10).
　横ビーム内箱１２は、横ビーム外箱１１の開口部から横ビーム外箱１１の内部空間に挿入される。この状態で、横ビーム内箱１２の先端部（換言すれば、車幅方向における外側の端部）は、横ビーム外箱１１の開口部から車幅方向における外側に突出する。 The horizontal beam inner box 12 is inserted into the inner space of the horizontal beam outer box 11 from the opening of the horizontal beam outer box 11. In this state, the front end portion of the lateral beam inner box 12 (in other words, the outer end portion in the vehicle width direction) protrudes outward from the opening of the lateral beam outer box 11 in the vehicle width direction.
　このような横ビーム内箱１２は、油圧シリンダ（図示省略）もしくは手動により、横ビーム外箱１１に対して車幅方向に移動可能である。横ビーム内箱１２が横ビーム外箱１１に対して車幅方向に移動することにより、横アウトリガ１０は、車幅方向に伸縮する。 Such a horizontal beam inner box 12 can be moved in the vehicle width direction with respect to the horizontal beam outer box 11 by a hydraulic cylinder (not shown) or manually. When the lateral beam inner box 12 moves in the vehicle width direction relative to the lateral beam outer box 11, the lateral outrigger 10 expands and contracts in the vehicle width direction.
　一方のアウトリガ装置１の場合、横アウトリガ１０の収縮状態において、横ビーム内箱１２が、横ビーム外箱１１に対して車幅方向における外側（図１および図２の左側であって、第１方向ともいう。）に移動することにより伸長状態となる。 In the case of one outrigger device 1, in the contracted state of the lateral outrigger 10, the lateral beam inner box 12 is outside the lateral beam outer box 11 in the vehicle width direction (on the left side in FIGS. 1 and 2, (It is also called a direction.) It will be in an expansion | extension state by moving to.
　一方、他方のアウトリガ装置１（後側アウトリガともいう。）の場合、横アウトリガ１０の収縮状態において、横ビーム内箱１２が、横ビーム外箱１１に対して車幅方向における外側（図１および図２の右側であって、第２方向ともいう。）に移動することにより伸長状態となる。 On the other hand, in the case of the other outrigger device 1 (also referred to as a rear outrigger), when the lateral outrigger 10 is in the contracted state, the lateral beam inner box 12 is outside the lateral beam outer box 11 in the vehicle width direction (see FIG. 1 and FIG. 2 is the right side of FIG. 2 and is also referred to as the second direction).

　左右一対のアウトリガ装置１は、図１に示すように、前後方向にずれて配置される。具体的には、一方（前側）のアウトリガ装置１の横アウトリガ１０（前側横アウトリガともいう。）の後方に隣接した位置に、他方（後側）のアウトリガ装置１の横アウトリガ１０（後側横アウトリガともいう。）が、前後方向に隣り合って配置される。 The pair of left and right outrigger devices 1 are displaced in the front-rear direction as shown in FIG. Specifically, the lateral outrigger 10 (rear side lateral) of the other (rear) outrigger device 1 is positioned adjacent to the rear side of the lateral outrigger 10 (also referred to as front lateral outrigger) of one (front side) outrigger device 1. Are also adjacent to each other in the front-rear direction.
　一方（前側）のアウトリガ装置１の横アウトリガ１０と、他方（後側）のアウトリガ装置１の横アウトリガ１０とは、車幅方向において対称となるように配置される。また、一方（前側）のアウトリガ装置１の横アウトリガ１０と、他方（後側）のアウトリガ装置１の横アウトリガ１０とは、車幅方向においてもずれて配置される。 The lateral outrigger 10 of one (front side) outrigger device 1 and the lateral outrigger 10 of the other (rear side) outrigger device 1 are arranged symmetrically in the vehicle width direction. Further, the lateral outrigger 10 of the one (front side) outrigger device 1 and the lateral outrigger 10 of the other (rear side) outrigger device 1 are arranged to be shifted in the vehicle width direction.
　具体的には、一方（前側）のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム内箱１２）の先端部（図１の左端部）は、他方（後側）のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム外箱１１）の基端面（図１の左端面）よりも、車幅方向における外側（図１の左側）に突出する。 Specifically, the distal end portion (left end portion in FIG. 1) of the lateral outrigger 10 (specifically, the lateral beam inner box 12) of one (front side) outrigger device 1 is the other (rear side) outrigger device 1. 1 protrudes outward (left side in FIG. 1) in the vehicle width direction from the base end surface (left end surface in FIG. 1) of the lateral outrigger 10 (specifically, the lateral beam outer box 11).
　他方（後側）のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム内箱１２）の先端部（図１の右端部）は、一方（前側）のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム外箱１１）の基端面（図１の右端面）よりも、車幅方向における外側（図１の右側）に突出する。 The distal end portion (right end portion in FIG. 1) of the lateral outrigger 10 (specifically, the lateral beam inner box 12) of the other (rear) outrigger device 1 is the lateral outrigger 10 ( Specifically, it protrudes outward (right side in FIG. 1) in the vehicle width direction from the base end surface (right end surface in FIG. 1) of the lateral beam outer box 11).
　換言すれば、一対のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム内箱１２）の先端部は、互いに隣り合うアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム外箱１１）の基端面よりも車幅方向における外側に突出している。ただし、格納状態において、一対のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム内箱１２）の先端部は、車両の車幅方向における両端よりも、車幅方向における内側に位置する。 In other words, the distal end portion of the lateral outrigger 10 (specifically, the lateral beam inner box 12) of the pair of outrigger devices 1 is the lateral outrigger 10 (specifically, the lateral beam outer box) of the adjacent outrigger devices 1. 11) protrudes outward in the vehicle width direction from the base end face. However, in the retracted state, the distal end portions of the lateral outriggers 10 (specifically, the lateral beam inner box 12) of the pair of outrigger devices 1 are located on the inner side in the vehicle width direction than the both ends in the vehicle width direction of the vehicle. .
　一方（前側）のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム内箱１２）の先端部（図１の左端部）の後方、かつ、他方（後側）のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム外箱１１）と車幅方向に重なる略直方体状の空間を、第１縦アウトリガ配置空間という。 The rear of the lateral outrigger 10 (specifically, the lateral beam inner box 12) of one (front side) outrigger device 1 is located behind the front end portion (left end portion in FIG. 1) and the lateral side of the other (rear side) outrigger device 1. A substantially rectangular parallelepiped space that overlaps the outrigger 10 (specifically, the lateral beam outer box 11) in the vehicle width direction is referred to as a first vertical outrigger arrangement space.
　他方（後側）のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム内箱１２）の先端部（図１の右端部）の前方、かつ、一方（前側）のアウトリガ装置１の横アウトリガ１０（具体的には、横ビーム外箱１１）と車幅方向に重なる略直方体状の空間を、第２縦アウトリガ配置空間という。 The front side of the lateral outrigger 10 (specifically, the lateral beam inner box 12) of the other (rear) outrigger device 1 (in front of the right end portion in FIG. 1) and the lateral side of one (front side) outrigger device 1 A substantially rectangular parallelepiped space overlapping the outrigger 10 (specifically, the lateral beam outer box 11) in the vehicle width direction is referred to as a second vertical outrigger arrangement space.
　一対のアウトリガ装置１の格納状態において、第１縦アウトリガ配置空間および第２縦アウトリガ配置空間にはそれぞれ、縦アウトリガ２０の一部が格納される。このような格納状態において、一対のアウトリガ装置１の縦アウトリガ２０はそれぞれ、先端部が上方を向いて起立する。 In the storage state of the pair of outrigger devices 1, a part of the vertical outrigger 20 is stored in each of the first vertical outrigger arrangement space and the second vertical outrigger arrangement space. In such a stored state, each of the vertical outriggers 20 of the pair of outrigger devices 1 stands up with its tip portion facing upward.
　また、格納状態において、一対のアウトリガ装置１の縦アウトリガ２０はそれぞれ、横アウトリガ１０（具体的には、横ビーム内箱１２）の先端よりも、車幅方向における外側に突出しない。本実施形態の場合、縦アウトリガ２０および横アウトリガ１０の車幅方向における外側の面は、同一平面上に位置する。なお、横アウトリガ１０の車幅方向における外側の面は、縦アウトリガ２０の車幅方向における外側の面よりも、車幅方向における内側に位置してもよい。格納状態から使用状態へと移行する際、一対のアウトリガ装置１の横アウトリガ１０は、互いに車幅方向における反対側へと伸長する。 Further, in the retracted state, the vertical outriggers 20 of the pair of outrigger devices 1 do not protrude outward in the vehicle width direction from the tip of the lateral outrigger 10 (specifically, the lateral beam inner box 12). In the present embodiment, the outer surfaces of the vertical outrigger 20 and the horizontal outrigger 10 in the vehicle width direction are located on the same plane. Note that the outer surface of the lateral outrigger 10 in the vehicle width direction may be positioned more inside in the vehicle width direction than the outer surface of the vertical outrigger 20 in the vehicle width direction. When shifting from the storage state to the use state, the lateral outriggers 10 of the pair of outrigger devices 1 extend to opposite sides in the vehicle width direction.
　縦アウトリガ２０は、横アウトリガ１０とともに車幅方向に移動可能に設けられる。このような縦アウトリガ２０は、自身の軸方向において伸縮可能である。具体的には、縦アウトリガ２０は、ジャッキ外箱２１（第一筒状部材ともいう。）と、ジャッキ内箱２２（第二筒状部材ともいう。）と、フロート２３とを有する。 The vertical outrigger 20 is provided so as to be movable in the vehicle width direction together with the horizontal outrigger 10. Such a vertical outrigger 20 can expand and contract in its own axial direction. Specifically, the vertical outrigger 20 includes a jack outer box 21 (also referred to as a first cylindrical member), a jack inner box 22 (also referred to as a second cylindrical member), and a float 23.
　ジャッキ外箱２１は、先端（図１および図２の上端）に開口部を有する。ジャッキ内箱２２は、ジャッキ外箱２１の内部空間に、ジャッキ外箱２１に対する軸方向の移動可能に配置される。ジャッキ内箱２２の先端部は、ジャッキ外箱２１の開口部から突出する。フロート２３は、ジャッキ内箱２２の先端部に設けられる。 The jack outer box 21 has an opening at the tip (the upper end in FIGS. 1 and 2). The jack inner box 22 is disposed in the inner space of the jack outer box 21 so as to be movable in the axial direction with respect to the jack outer box 21. The tip of the jack inner box 22 protrudes from the opening of the jack outer box 21. The float 23 is provided at the tip of the jack inner box 22.
　このような縦アウトリガ２０は、使用状態において、先端が下方を向いて起立する。一方、縦アウトリガ２０は、格納状態において先端が上方を向いて起立する。 Such a vertical outrigger 20 stands up with its tip facing downward when in use. On the other hand, the vertical outrigger 20 stands up with its tip facing upward in the retracted state.
　縦アウトリガ２０は、ジャッキ外箱２１とジャッキ内箱２２との間（たとえば、縦アウトリガ２０の内側）にジャッキシリンダ４９（アクチュエータともいう。図２参照）を有する。ジャッキシリンダ４９は、ジャッキ内箱２２をジャッキ外箱２１に対して移動させる。このようなジャッキ内箱２２の移動に基づいて、縦アウトリガ２０は、自身の軸方向において伸縮する。 The vertical outrigger 20 has a jack cylinder 49 (also referred to as an actuator, see FIG. 2) between the jack outer box 21 and the jack inner box 22 (for example, inside the vertical outrigger 20). The jack cylinder 49 moves the jack inner box 22 relative to the jack outer box 21. Based on such movement of the jack inner box 22, the vertical outrigger 20 expands and contracts in its own axial direction.
　図１に示すように、横アウトリガ１０と縦アウトリガ２０とは、横アウトリガ１０に固定された一対の第１ブラケット１３および縦アウトリガ２０に固定された一対の第２ブラケット２４を介して連結される。一対の第１ブラケット１３は、一体に形成された板状部材であって、横アウトリガ１０における横ビーム内箱１２の先端部に固定される。 As shown in FIG. 1, the horizontal outrigger 10 and the vertical outrigger 20 are connected via a pair of first brackets 13 fixed to the horizontal outrigger 10 and a pair of second brackets 24 fixed to the vertical outrigger 20. . The pair of first brackets 13 are integrally formed plate-like members and are fixed to the distal end portion of the lateral beam inner box 12 in the lateral outrigger 10.
　一対の第１ブラケット１３は、前後方向に離れている。一対の第１ブラケット１３はそれぞれ、ピン挿入孔１４を有する。一対の第２ブラケット２４はそれぞれ、縦アウトリガ２０におけるジャッキ外箱２１の先端部に、前後方向に離れて設けられる。一対の第２ブラケット２４はそれぞれ、ピン挿入孔を有する。 The pair of first brackets 13 are separated in the front-rear direction. Each of the pair of first brackets 13 has a pin insertion hole 14. The pair of second brackets 24 is provided at the front end portion of the jack outer box 21 of the vertical outrigger 20 so as to be separated in the front-rear direction. Each of the pair of second brackets 24 has a pin insertion hole.
　図３に示す使用状態（展開状態ともいう。）において、一対の第１ブラケット１３のピン挿入孔１４と、一対の第２ブラケット２４のピン挿入孔とが、車幅方向に重なる。この状態で、一対の第１ブラケット１３のピン挿入孔１４および一対の第２ブラケット２４のピン挿入孔に、それぞれピン２５が挿入される。この状態において、縦アウトリガ２０は、横アウトリガ１０に強固に固定される。 3, the pin insertion holes 14 of the pair of first brackets 13 and the pin insertion holes of the pair of second brackets 24 overlap in the vehicle width direction. In this state, the pins 25 are respectively inserted into the pin insertion holes 14 of the pair of first brackets 13 and the pin insertion holes of the pair of second brackets 24. In this state, the vertical outrigger 20 is firmly fixed to the horizontal outrigger 10.
　縦アウトリガ２０の格納状態では、一方の第１ブラケット２４のピン挿入孔１４と、一方の第２ブラケット２４のピン挿入孔にのみピン２５を挿入した状態で、縦アウトリガ２０を、先端が上方を向いた状態で保持する。 In the retracted state of the vertical outrigger 20, the vertical outrigger 20 is placed with the tip upward in the state where the pin 25 is inserted only into the pin insertion hole 14 of one first bracket 24 and the pin insertion hole of one second bracket 24. Hold face up.
　具体的には、一方（具体的には、前側）のアウトリガ装置１の格納状態において、縦アウトリガ２０（前側縦アウトリガともいう。）は、上述の第１縦アウトリガ配置空間を含む領域に配置される。 Specifically, in the retracted state of one (specifically, the front) outrigger device 1, the vertical outrigger 20 (also referred to as the front vertical outrigger) is disposed in a region including the first vertical outrigger arrangement space described above. The
　一方、他方（具体的には、後側）のアウトリガ装置１の格納状態において、縦アウトリガ２０（後側縦アウトリガともいう。）は、上述の第２縦アウトリガ配置空間を含む領域に配置される。 On the other hand, in the retracted state of the other (specifically, the rear) outrigger device 1, the vertical outrigger 20 (also referred to as a rear vertical outrigger) is disposed in a region including the above-described second vertical outrigger arrangement space. .
　一対のアウトリガ装置１において、縦アウトリガ２０はそれぞれ、横ビーム内箱１２の先端部の周面（たとえば、前方または後方の側面）に対して、ピン連結される。つまり、縦アウトリガ２０は、横ビーム内箱１２の車幅方向における外側に取付けられるのではなく、横ビーム内箱１２の車幅方向における外端面（先端面ともいう。）よりも車幅方向における内側に取付けられる。 In the pair of outrigger devices 1, each of the vertical outriggers 20 is pin-connected to the peripheral surface (for example, the front or rear side surface) of the front end portion of the horizontal beam inner box 12. That is, the vertical outrigger 20 is not attached to the outside of the horizontal beam inner box 12 in the vehicle width direction, but rather in the vehicle width direction than the outer end surface (also referred to as the front end surface) of the horizontal beam inner box 12 in the vehicle width direction. Mounted on the inside.
　具体的には、縦アウトリガ２０はそれぞれ、横ビーム内箱１２の先端部の周面に、第１ブラケット１３および第２ブラケット２４に挿通されたピン２５により連結される。ピン２５の中心軸は、車幅方向に平行である。したがって、縦アウトリガ２０はそれぞれ、横ビーム内箱１２に対して、ピン２５を揺動中心軸とした揺動可能である。 Specifically, each of the vertical outriggers 20 is connected to the peripheral surface of the distal end portion of the horizontal beam inner box 12 by a pin 25 inserted through the first bracket 13 and the second bracket 24. The central axis of the pin 25 is parallel to the vehicle width direction. Accordingly, each of the vertical outriggers 20 can swing with respect to the horizontal beam inner box 12 with the pin 25 as the swing center axis.
（格納構造について）
　つぎに、アウトリガ装置１における縦アウトリガ２０の格納構造を図３および図４に基づき説明する。
　本発明に係るアウトリガ装置１は、リンク機構３０を有する。リンク機構３０は、ジャッキ内箱２２の収縮動作を利用して、縦アウトリガ２０を上向き（換言すれば、縦アウトリガ２０の先端が上方を向いた状態）に格納する動作と、下向き（換言すれば、縦アウトリガ２０の先端が下方を向いた状態）に設置する動作とを行う。本実施形態において、リンク機構３０は、縦アウトリガ２０の車幅方向における内側面に設けられる。 (About storage structure)
Next, the storage structure of the vertical outrigger 20 in the outrigger apparatus 1 will be described with reference to FIGS. 3 and 4.
The outrigger device 1 according to the present invention has a link mechanism 30. The link mechanism 30 uses the contraction operation of the jack inner box 22 to store the vertical outrigger 20 upward (in other words, the state where the tip of the vertical outrigger 20 faces upward) and downward (in other words, And the operation of installing the vertical outrigger 20 in a state in which the tip of the vertical outrigger 20 faces downward. In the present embodiment, the link mechanism 30 is provided on the inner side surface of the vertical outrigger 20 in the vehicle width direction.
　具体的には、リンク機構３０は、押し棒３１（直動部材ともいう。）と、揺動リンク３２（回動部材ともいう。）と、連結リンク３３とを有する。リンク機構３０の幅寸法（換言すれば、図３および図４の左右方向における寸法であって、前後方向における寸法）は、ほぼ縦アウトリガ２０の幅寸法内に収まる。 Specifically, the link mechanism 30 includes a push rod 31 (also referred to as a linear motion member), a swing link 32 (also referred to as a rotation member), and a connection link 33. The width dimension of the link mechanism 30 (in other words, the dimension in the left-right direction in FIGS. 3 and 4 and the dimension in the front-rear direction) is substantially within the width dimension of the vertical outrigger 20.
　押し棒３１は、ジャッキ外箱２１に取付けられる。具体的には、押し棒３１は、ジャッキ外箱２１の幅方向における内側面の長手方向２個所に取付けられた保持部材３４に挿通された状態で、ジャッキ外箱２１に支持される。すなわち、保持部材３４はそれぞれ、ジャッキ外箱２１の車幅方向における内側面に設けられる。押し棒３１は、保持部材３４にガイドされながら、ジャッキ外箱２１の長手方向（換言すれば、ジャッキ外箱２１の中心軸の方向）に沿って移動できる。 The push bar 31 is attached to the jack outer box 21. Specifically, the push bar 31 is supported by the jack outer box 21 in a state where the push bar 31 is inserted into the holding members 34 attached at two positions in the longitudinal direction of the inner side surface in the width direction of the jack outer box 21. That is, each holding member 34 is provided on the inner side surface of the jack outer box 21 in the vehicle width direction. The push bar 31 can move along the longitudinal direction of the jack outer box 21 (in other words, the direction of the central axis of the jack outer box 21) while being guided by the holding member 34.
　揺動リンク３２は、略三角形状の板部材であって、横ビーム内箱１２の先端部とジャッキ外箱２１とにピン連結される。具体的には、揺動リンク３２は、図３における上端部３２ａと、下端部３２ｂと、支点部３２ｃとを有する。上端部３２ａ、下端部３２ｂ、および支点部３２ｃはそれぞれ、ピンを通す孔を有する。 The swing link 32 is a substantially triangular plate member, and is pin-connected to the tip of the lateral beam inner box 12 and the jack outer box 21. Specifically, the swing link 32 has an upper end portion 32a, a lower end portion 32b, and a fulcrum portion 32c in FIG. The upper end portion 32a, the lower end portion 32b, and the fulcrum portion 32c each have a hole through which a pin passes.
　上端部３２ａの孔には、第１ピン３５が挿通される。下端部３２ｂの孔には、第２ピン３６が挿通される。支点部３２ｃの孔には、第３ピン３７が挿通される。第１ピン３５、第２ピン３６、および第３ピン３７の中心軸は、車幅方向に平行である。 The first pin 35 is inserted through the hole in the upper end 32a. The second pin 36 is inserted through the hole in the lower end 32b. The third pin 37 is inserted through the hole of the fulcrum part 32c. The central axes of the first pin 35, the second pin 36, and the third pin 37 are parallel to the vehicle width direction.
　第１ピン３５は、横ビーム内箱１２の先端に形成された第１ブラケット１３のピン孔にも挿入されている。第１ピン３５は、揺動リンク３２の回転支点である。すなわち、揺動リンク３２は、車幅方向に平行に配置された第１ピン３５を中心として、車幅方向に直交する（前後方向に平行な）面内において回動可能である。 The first pin 35 is also inserted into the pin hole of the first bracket 13 formed at the tip of the transverse beam inner box 12. The first pin 35 is a rotation fulcrum of the swing link 32. That is, the swing link 32 can rotate in a plane perpendicular to the vehicle width direction (parallel to the front-rear direction) around the first pin 35 disposed parallel to the vehicle width direction.
　第２ピン３６は、ジャッキ外箱２１の車幅方向における内側面に設けられたガイド部材４１によってガイドされる。ガイド部材４１は、縦アウトリガ２０の使用状態における上下方向（換言すれば、縦アウトリガ２０の中心軸に平行な方向）に長いガイド孔４２を有する。 The second pin 36 is guided by a guide member 41 provided on the inner surface of the jack outer box 21 in the vehicle width direction. The guide member 41 has a guide hole 42 that is long in the vertical direction (in other words, the direction parallel to the central axis of the vertical outrigger 20) in the usage state of the vertical outrigger 20.
　第２ピン３６は、揺動リンク３２における下端部３２ｂの孔に挿通されるとともに、ガイド孔４２に挿通される。このような第２ピン３６は、ガイド孔４２にガイドされつつ、ガイド孔４２の長手方向に沿って移動可能である。詳しい動作については後述するが、第２ピン３６がガイド孔４２内で移動することにより、ジャッキ外箱２１の所定方向の回動が許容される。 The second pin 36 is inserted into the hole of the lower end 32b of the swing link 32 and the guide hole 42. Such a second pin 36 is movable along the longitudinal direction of the guide hole 42 while being guided by the guide hole 42. Although the detailed operation will be described later, when the second pin 36 moves in the guide hole 42, the jack outer box 21 is allowed to rotate in a predetermined direction.
　第２ピン３６は、ピンのみの構成に限らず、たとえば、ピンにローラを設けたものであってもよい。このような構成によれば、第２ピン３６は、ガイド孔４２内において円滑に移動できる。このようなローラ付きピンを採用した構成も、本発明の技術的範囲に含まれる。 The second pin 36 is not limited to a pin-only configuration, and may be a pin provided with a roller, for example. According to such a configuration, the second pin 36 can move smoothly in the guide hole 42. A configuration employing such a pin with a roller is also included in the technical scope of the present invention.
　第３ピン３７は、揺動リンク３２の支点部３２ｃと連結リンク３３の一端（図３の上端）とを連結する。一方、連結リンク３３の他端（図３の下端）と押し棒３１の一端（図３の上端）とは、第４ピン３８により連結される。 The third pin 37 connects the fulcrum part 32c of the swing link 32 and one end of the connection link 33 (the upper end in FIG. 3). On the other hand, the other end (lower end in FIG. 3) of the connection link 33 and one end (upper end in FIG. 3) of the push rod 31 are connected by a fourth pin 38.
　このようにして連結リンク３３は、揺動リンク３２と押し棒３１とを連結する。連結リンク３３は、押し棒３１の上下動（換言すれば、縦アウトリガ２０の中心軸に平行な移動）を揺動リンク３２に伝達する。揺動リンク３２は、連結リンク３３から伝達される力に基づいて所定方向に回動する。 In this way, the connection link 33 connects the swing link 32 and the push rod 31. The connecting link 33 transmits the vertical movement of the push bar 31 (in other words, movement parallel to the central axis of the vertical outrigger 20) to the swing link 32. The swing link 32 rotates in a predetermined direction based on the force transmitted from the connection link 33.
　上述のように揺動リンク３２が回動すると、第２ピン３６は、ガイド部材４１のガイド孔４２内を上下に（ガイド孔４２の長手方向に沿って）摺動しながら、ガイド孔４２の内面を所定方向（図４のＦ２の方向）に押圧する。このような押圧にともない、縦アウトリガ２０は、第１ピン３５を中心として、所定方向（図５の時計回りの方向）に回転する。すなわち、第２ピン３６は、ガイド孔４２内を移動しながら、ガイド孔４２の内面を押圧することにより、ガイド部材４１を介して縦アウトリガ２０に回転力（回転トルク）を伝達する。 When the swing link 32 rotates as described above, the second pin 36 slides up and down in the guide hole 42 of the guide member 41 (along the longitudinal direction of the guide hole 42) while pressing the inner surface in a predetermined direction (direction of F 2 in FIG. 4). With such pressing, the vertical outrigger 20 rotates in a predetermined direction (the clockwise direction in FIG. 5) around the first pin 35. That is, the second pin 36 transmits a rotational force (rotational torque) to the vertical outrigger 20 via the guide member 41 by pressing the inner surface of the guide hole 42 while moving in the guide hole 42.
　そして、図４に示すように、第３ピン３７と第４ピン３８とを結ぶ線分と、第１ピン３５とは、距離ｄだけ離れている。この場合、ｄ×Ｆ１＝ｌ×Ｆ２となるので、力Ｆ２は、揺動リンク３２を側方に揺動させる力を生じさせる。 As shown in FIG. 4, the line connecting the third pin 37 and the fourth pin 38 is separated from the first pin 35 by a distance d. In this case, since d × F 1 = 1 × F 2 , the force F 2 generates a force that causes the swing link 32 to swing sideways.
　ジャッキ内箱２２の先端部（図３の下端部）には、当て金２６が取付けられている。当て金２６は、ジャッキ内箱２２の車幅方向における内側面の先端部に設けられる。このような当て金２６は、押し棒３１の他端（図３の下端）に下方（換言すれば、縦アウトリガ２０の先端側）から当って、押し棒３１を押し上げる（換言すれば、縦アウトリガ２０の基端側に移動させる）。 A stopper 26 is attached to the tip of the jack inner box 22 (the lower end in FIG. 3). The stopper 26 is provided at the tip of the inner surface of the jack inner box 22 in the vehicle width direction. Such a stopper 26 hits the other end (lower end in FIG. 3) of the push bar 31 from below (in other words, the front end side of the vertical outrigger 20) and pushes up the push bar 31 (in other words, the vertical outrigger). 20 to the proximal side).
　つまり、縦アウトリガ２０に内蔵されているジャッキシリンダによりジャッキ内箱２２がジャッキ外箱２１内に引き込まれると、当て金２６が押し棒３１を押し上げる。 That is, when the jack inner box 22 is pulled into the jack outer box 21 by the jack cylinder built in the vertical outrigger 20, the stopper 26 pushes up the push bar 31.
　上述のように、押し棒３１が押し上げられると（縦アウトリガ２０の軸方向において直線運動すると）、連結リンク３３が、揺動リンク３２の支点部３２ｃを押す。すると、揺動リンク３２が、図４の時計回りの方向に回動する。この回動に基づく回転トルクは、第２ピン３６を介してガイド部材４１およびジャッキ外箱２１に伝わる。この結果、縦アウトリガ２０は、図４の時計回りの方向に回動する。 As described above, when the push bar 31 is pushed up (when it moves linearly in the axial direction of the vertical outrigger 20), the connecting link 33 pushes the fulcrum 32c of the swing link 32. Then, the swing link 32 rotates in the clockwise direction of FIG. The rotational torque based on this rotation is transmitted to the guide member 41 and the jack outer box 21 via the second pin 36. As a result, the vertical outrigger 20 rotates in the clockwise direction of FIG.
（格納動作について）
　つぎに、縦アウトリガ２０の格納動作を説明する。
（１）格納する前の状態（使用状態）について
　図３は、縦アウトリガ２０を格納する前の状態であると同時に使用状態（縦アウトリガ２０の使用状態ともいう。）も示している。使用状態において、縦アウトリガ２０は、横アウトリガ１０（具体的には横ビーム内箱１２）の先端部の下方に位置する。 (About storage operation)
Next, the storing operation of the vertical outrigger 20 will be described.
(1) About a state before use (usage state) FIG. 3 shows a use state (also referred to as a use state of the vertical outrigger 20) as well as a state before the vertical outrigger 20 is stored. In the use state, the vertical outrigger 20 is located below the front end portion of the horizontal outrigger 10 (specifically, the horizontal beam inner box 12).
　換言すれば、使用状態において、縦アウトリガ２０の上端面（基端面ともいう。）は、横アウトリガ１０（具体的には横ビーム内箱１２）の先端部の下側面と上下方向に対向する。 In other words, in the state of use, the upper end surface (also referred to as the base end surface) of the vertical outrigger 20 faces the lower surface of the distal end portion of the horizontal outrigger 10 (specifically, the horizontal beam inner box 12) in the vertical direction.
　使用状態において、縦アウトリガ２０の上端は、左右２本のピン２５で、横アウトリガ１０の横ビーム内箱１２の先端部に強固に固定される。したがって、クレーン車体は、縦アウトリガ２０のジャッキアップによって安定的に支えられる。使用状態から、縦アウトリガ２０を格納する場合には、図３における右側のピン２５を抜く。 In the state of use, the upper end of the vertical outrigger 20 is firmly fixed to the front end portion of the horizontal beam inner box 12 of the horizontal outrigger 10 by two pins 25 on the left and right. Therefore, the crane body is stably supported by jacking up the vertical outrigger 20. When the vertical outrigger 20 is stored from the use state, the right pin 25 in FIG. 3 is pulled out.
　すると、縦アウトリガ２０は、図３における時計回りの方向への回動が可能な準備状態となる。なお、使用状態から格納状態へ移行する際、一方（具体的には、前側）のアウトリガ装置１においては、一対のピン２５のうちの前側のピン２５を抜く。すなわち、一方のアウトリガ装置１においては、一対のピン２５のうちの後側のピン２５が、縦アウトリガ２０の回動中心となる。 Then, the vertical outrigger 20 is in a ready state in which it can rotate in the clockwise direction in FIG. When shifting from the use state to the storage state, in one (specifically, the front side) outrigger device 1, the front side pin 25 of the pair of pins 25 is pulled out. That is, in one outrigger device 1, the rear pin 25 of the pair of pins 25 serves as the rotation center of the vertical outrigger 20.
　一方、使用状態から格納状態へ移行する際、他方（具体的には、後側）のアウトリガ装置１においては、一対のピン２５のうちの後側のピン２５を抜く。すなわち、他方のアウトリガ装置１においては、一対のピン２５のうちの前側のピン２５が、縦アウトリガ２０の回動中心となる。 On the other hand, when shifting from the use state to the storage state, the rear pin 25 of the pair of pins 25 is pulled out in the other (specifically, the rear) outrigger device 1. That is, in the other outrigger device 1, the front pin 25 of the pair of pins 25 serves as the rotation center of the vertical outrigger 20.
（２）縦アウトリガの収縮動作について
　縦アウトリガ２０は、自身の中心軸の方向において伸縮可能である。縦アウトリガ１の収縮動作は、ジャッキ外箱２１に対して、ジャッキ内箱２２が移動することにより行われる。なお、アウトリガ装置１の使用状態において、縦アウトリガ２０は、伸長状態にある。伸長状態における縦アウトリガ２０の長さ寸法は、使用状況（たとえば、地面の形状など）に応じて適宜変更される。 (2) About contraction operation | movement of vertical outrigger The vertical outrigger 20 can be expanded-contracted in the direction of its own central axis. The contraction operation of the vertical outrigger 1 is performed by moving the jack inner box 22 with respect to the jack outer box 21. In the use state of the outrigger device 1, the vertical outrigger 20 is in an extended state. The length dimension of the vertical outrigger 20 in the extended state is appropriately changed according to the use situation (for example, the shape of the ground).
　一方、アウトリガ装置１の格納状態において、縦アウトリガ２０は、収縮状態にある。収縮状態において、ジャッキ内箱２２は、ジャッキ外箱２１に最も入り込む。具体的には、縦アウトリガ２０が、伸長状態から収縮状態へ移行する際、図４に示すように、ジャッキ内箱２２が、ジャッキ外箱２１に対して上方へと移動しつつ内側に入り込む。 On the other hand, in the retracted state of the outrigger device 1, the vertical outrigger 20 is in a contracted state. In the contracted state, the jack inner box 22 enters the jack outer box 21 most. Specifically, when the vertical outrigger 20 shifts from the extended state to the contracted state, the jack inner box 22 enters the inner side while moving upward with respect to the jack outer box 21 as shown in FIG.
　縦アウトリガ２０が、伸長状態から収縮状態へ移行する途中において、当て金２６は、押し棒３１の下端に当接する。この状態から当て金２６が上方に変位すると、当て金２６が、押し棒３１を上方に押し上げる。ジャッキ内箱２２が、ジャッキ外箱２１の内側に可能な範囲で最も入り込んだ状態で、ジャッキ内箱２２の移動が停止する。このような動作は、縦アウトリガ２０内に設けたジャッキシリンダの収縮動作に基づいて行われる。 In the middle of the vertical outrigger 20 shifting from the extended state to the contracted state, the stopper 26 comes into contact with the lower end of the push bar 31. When the stopper 26 is displaced upward from this state, the stopper 26 pushes the push bar 31 upward. The movement of the jack inner box 22 is stopped in a state where the jack inner box 22 has entered the inside of the jack outer box 21 as much as possible. Such an operation is performed based on a contraction operation of a jack cylinder provided in the vertical outrigger 20.
（３）縦アウトリガの回動動作（格納初期）について
　上述のように、縦アウトリガ２０が、伸長状態から収縮状態へと移行する途中において、当て金２６は、押し棒３１を上方に押し上げる。押し棒２１が上方に押し上げられると、図５に示すように、押し棒３１が、連結リンク３３を介して揺動リンク３２の支点部３２ｃ（図３参照）を押し上げる。 (3) Rotating operation (initial storage) of the vertical outrigger As described above, the latch 26 pushes the push bar 31 upward while the vertical outrigger 20 is moving from the extended state to the contracted state. When the push rod 21 is pushed upward, as shown in FIG. 5, the push rod 31 pushes up the fulcrum portion 32 c (see FIG. 3) of the swing link 32 via the connection link 33.
　すると、揺動リンク３２は、図５の時計回りの方向に回動する。このような揺動リンク３２の回動動作は、第２ピン３６からガイド部材４１およびジャッキ外箱２１に伝わる。この結果、縦アウトリガ２０が、図５の時計回りの方向に回動する。 Then, the swing link 32 rotates in the clockwise direction of FIG. The pivoting movement of the swing link 32 is transmitted from the second pin 36 to the guide member 41 and the jack outer box 21. As a result, the vertical outrigger 20 rotates in the clockwise direction of FIG.
　なお、一方のアウトリガ装置１（前側アウトリガ）においては、縦アウトリガ２０は、伸長状態から、ピン２５を中心に後方に回動する。一方、他方のアウトリガ装置１（後側アウトリガ）においては、縦アウトリガ２０は、伸長状態から、ピン２５を中心に前方に回動する。 In one outrigger device 1 (front outrigger), the vertical outrigger 20 rotates backward about the pin 25 from the extended state. On the other hand, in the other outrigger device 1 (rear outrigger), the vertical outrigger 20 rotates forward about the pin 25 from the extended state.
（４）縦アウトリガの回動動作（格納中期）について
　図６は、図５に示す状態から縦アウトリガ２０がさらに収縮し、縦アウトリガ２０が、図６における左斜め下を向くまで回動した状態を示している。図７は、図６に示す状態から縦アウトリガ２０がさらに収縮し、縦アウトリガ２０が、図７における左斜め上まで回動した状態を示している。これらの動作は、縦アウトリガ２０内に設けたジャッキシリンダ４９（図２参照）の収縮動作の継続により行われる。 (4) Rotating operation of the vertical outrigger (mid-storage period) FIG. 6 shows a state in which the vertical outrigger 20 is further contracted from the state shown in FIG. 5 and the vertical outrigger 20 is rotated diagonally to the left in FIG. Is shown. FIG. 7 shows a state where the vertical outrigger 20 is further contracted from the state shown in FIG. 6 and the vertical outrigger 20 is rotated to the upper left in FIG. These operations are performed by continuing the contraction operation of the jack cylinder 49 (see FIG. 2) provided in the vertical outrigger 20.
（５）縦アウトリガの回動動作（格納終期）について
　図８は、図７に示す状態から縦アウトリガ２０がさらに収縮し、縦アウトリガ２０が、図８における上向きに直立するまで回動した状態を示している。また、この状態は、図１および図２に示す縦アウトリガ２０の状態（換言すれば、縦アウトリガ２０の格納状態）でもある。 (5) Rotating operation (end of storage) of the vertical outrigger FIG. 8 shows a state in which the vertical outrigger 20 is further contracted from the state shown in FIG. 7 and the vertical outrigger 20 is rotated upright in FIG. Show. This state is also the state of the vertical outrigger 20 shown in FIGS. 1 and 2 (in other words, the storage state of the vertical outrigger 20).
　縦アウトリガ２０の格納状態では、図１および図２に示すように、縦アウトリガ２０は、横アウトリガ１０における横ビーム内箱１２の先端部側方に位置している。具体的には、一方のアウトリガ装置１（前側アウトリガ装置ともいう。）の格納状態において、縦アウトリガ２０は、基端部が、横アウトリガ１０（具体的には、横ビーム内箱１２）の先端部の後側、かつ、他方のアウトリガ装置１（後側アウトリガ装置ともいう。）の横アウトリガ１０の基端面（図１および図２の左端面）と車幅方向に対向する第１縦アウトリガ配置空間に配置される。この状態において、一方のアウトリガ装置１の縦アウトリガ２０は、先端が上方を向いて起立する。 In the retracted state of the vertical outrigger 20, the vertical outrigger 20 is located on the side of the distal end portion of the horizontal beam inner box 12 in the horizontal outrigger 10 as shown in FIGS. 1 and 2. Specifically, in the retracted state of one outrigger device 1 (also referred to as a front outrigger device), the vertical outrigger 20 has a proximal end portion at the distal end of the lateral outrigger 10 (specifically, the lateral beam inner box 12). 1st vertical outrigger arrangement facing the base end surface (the left end surface in FIGS. 1 and 2) of the lateral outrigger 10 of the rear outboard portion and the other outrigger device 1 (also referred to as a rear outrigger device). Arranged in space. In this state, the vertical outrigger 20 of one outrigger device 1 stands up with the tip facing upward.
　また、他方のアウトリガ装置１の格納状態において、縦アウトリガ２０は、基端部が、横アウトリガ１０（具体的には、横ビーム内箱１２）の先端部の前側、かつ、一方のアウトリガ装置１の横アウトリガ１０の基端面（図１および図２の右端面）と車幅方向に対向する第１縦アウトリガ配置空間に配置される。この状態において、他方のアウトリガ装置１の縦アウトリガ２０は、先端が上方を向いて起立する。 In the retracted state of the other outrigger device 1, the vertical outrigger 20 has a base end on the front side of the distal end portion of the lateral outrigger 10 (specifically, the lateral beam inner box 12) and one outrigger device 1. Are arranged in a first vertical outrigger arrangement space facing the base end face (the right end face in FIGS. 1 and 2) of the horizontal outrigger 10 in the vehicle width direction. In this state, the vertical outrigger 20 of the other outrigger device 1 stands up with its tip facing upward.
　なお、ピン２５などの部材と横ビーム外箱１１の先端部との干渉を防止する干渉防止部（たとえば、切欠きなど）が、適宜設けられてもよい。 In addition, an interference prevention part (for example, a notch etc.) which prevents interference with members, such as the pin 25, and the front-end | tip part of the horizontal beam outer box 11 may be provided suitably.
（設置動作について）
　つぎに、格納状態から使用状態への設置動作を説明する。
　設置動作は、基本的に上述の格納動作の逆の動作により行う。つまり、図８に示す状態において、縦アウトリガ２０内に設けたジャッキシリンダ４９（図２参照）を伸長させると、図７→図６→図５に示す順に縦アウトリガ２０が、各図における反時計回りの方向に回動する。そして、図５に示す状態において手動により縦アウトリガ２０を直立下向きの状態（図４に示す状態）にする。この状態において、縦アウトリガ２０の上端部を、２本のピン２５により横ビーム内箱１２に固定する。ここからさらに、使用状況に応じて適宜の長さだけ縦アウトリガ２０を伸長させれば、クレーン車体が、アウトリガ装置１により安定的に支持された状態となる。 (About installation operation)
Next, the installation operation from the storage state to the use state will be described.
The installation operation is basically performed by the reverse operation of the above-described storage operation. That is, when the jack cylinder 49 (see FIG. 2) provided in the vertical outrigger 20 is extended in the state shown in FIG. 8, the vertical outrigger 20 is counterclockwise in the order shown in FIGS. Rotate in the direction of rotation. Then, in the state shown in FIG. 5, the vertical outrigger 20 is manually brought into an upright downward state (the state shown in FIG. 4). In this state, the upper end portion of the vertical outrigger 20 is fixed to the horizontal beam inner box 12 by the two pins 25. If the longitudinal outrigger 20 is further extended by an appropriate length according to the usage situation from here, the crane vehicle body is stably supported by the outrigger device 1.
（アウトリガ装置１の作用・効果について）
　積載型トラッククレーンは、アウトリガ装置の格納時の横幅寸法がトラック車体の車幅を越えることができないという制約を受ける。このような制約のなかで、本実施形態に係るアウトリガ装置１は、最大限の張出し幅を実現できる。具体的には、本実施形態に係るアウトリガ装置１は、以下の（効果１）～（効果４）の作用・効果を奏する。 (Operation and effect of the outrigger device 1)
The load-type truck crane is subject to the restriction that the lateral width when the outrigger device is retracted cannot exceed the width of the truck body. Under such restrictions, the outrigger device 1 according to the present embodiment can realize the maximum overhang width. Specifically, the outrigger device 1 according to the present embodiment has the following actions and effects (Effect 1) to (Effect 4).
（効果１）横ビーム外箱１１を長くできる
　本実施形態のリンク機構３０（押し棒３１、揺動リンク３２、連結リンク３３）は、図８に示すようにほぼ縦アウトリガ２０の幅寸法Ｗ（換言すれば、前後方向における寸法Ｗ）内に収まっており、側方に突出する部材はない。このため、縦アウトリガ２０を上方に向けた格納状態でリンク機構３０を構成する何れの部材も横アウトリガ１０の横ビーム外箱１１と干渉しない。この結果、横ビーム外箱１１を車体幅一杯まで延ばすことができ、アウトリガ装置１の張出し幅を大きくできる。 (Effect 1) The lateral beam outer box 11 can be lengthened. As shown in FIG. 8, the link mechanism 30 (the push bar 31, the swing link 32, the connecting link 33) of the present embodiment has a width dimension W ( In other words, there is no member protruding in the lateral direction within the dimension W) in the front-rear direction. Therefore, any member constituting the link mechanism 30 in the retracted state with the vertical outrigger 20 facing upward does not interfere with the lateral beam outer box 11 of the horizontal outrigger 10. As a result, the lateral beam outer box 11 can be extended to the full width of the vehicle body, and the overhang width of the outrigger device 1 can be increased.
（効果２）横ビーム内箱１２を長くできる
　ａ）本実施形態のアウトリガ装置１では、図１に示すように、縦アウトリガ２０は、横ビーム内箱１２の先端部の側面（換言すれば、横ビーム内箱１２の中心軸周りの周面）に取付けられ、かつ格納される。このため、横ビーム内箱１２の長さをクレーン車体の車体幅一杯まで延ばせる。この結果、横アウトリガ１０を張り出したときの張出し幅を、限界一杯まで広げられる。 (Effect 2) The transverse beam inner box 12 can be lengthened a) In the outrigger device 1 of the present embodiment, as shown in FIG. 1, the vertical outrigger 20 has a side surface (in other words, It is attached to and stored in the circumferential surface around the central axis of the transverse beam inner box 12. For this reason, the length of the transverse beam inner box 12 can be extended to the full width of the crane body. As a result, the overhang width when the lateral outrigger 10 is overhanged can be expanded to the full limit.
　ｂ）本実施形態におけるリンク機構３０（押し棒３１など）は、図１および図２に示すように、縦アウトリガ２０のジャッキ外箱２１の車幅方向における内側面に取付けられる。仮にリンク機構３０をジャッキ外箱２１の外側面に取付けると、横アウトリガ１０の格納状態における車幅方向の寸法を車幅内に収めるために、横ビーム内箱１２の長さが制約される。一方、本実施形態の場合、そのような制約がないので、横ビーム内箱１２を車体幅一杯まで延ばすことができる。 B) The link mechanism 30 (push bar 31 etc.) in this embodiment is attached to the inner side surface in the vehicle width direction of the jack outer box 21 of the vertical outrigger 20 as shown in FIGS. If the link mechanism 30 is attached to the outer surface of the jack outer box 21, the length of the horizontal beam inner box 12 is restricted in order to keep the dimension in the vehicle width direction in the retracted state of the horizontal outrigger 10 within the vehicle width. On the other hand, in the case of this embodiment, since there is no such restriction, the lateral beam inner box 12 can be extended to the full width of the vehicle body.
（効果３）
　本実施形態の場合、一方のアウトリガ装置１（前側アウトリガ装置ともいう。）と他方のアウトリガ装置1（後側アウトリガ装置ともいう。）とが、前後方向にずれて配置される。換言すれば、本実施形態の場合、一方のアウトリガ装置１の横アウトリガ１０と、他方のアウトリガ装置１の横アウトリガ１０とが、前後方向に重なるように隣り合って配置される。このため、各アウトリガ装置１における横アウトリガ１０の車幅方向における寸法を、最大限に大きくできる。すなわち、上述した特許文献１～３に開示されたアウトリガ装置のように、左右一対のアウトリガ装置が、前後方向にずれていない（換言すれば、車幅方向において重なる）構造の場合には、左右一対のアウトリガ装置を、車幅方向における一方の半部と、他方の半部とに配置する必要がある。このため、横アウトリガの車幅方向の寸法は、車幅の半分よりも小さい寸法に制限される。一方、本実施形態のように、左右一対のアウトリガ装置が、前後方向にずれた（換言すれば、車幅方向において重ならない）構造の場合には、左右一対のアウトリガ装置１の横アウトリガ１０の寸法をそれぞれ、車幅寸法に最大限に近づけられる。 (Effect 3)
In the case of this embodiment, one outrigger device 1 (also referred to as a front outrigger device) and the other outrigger device 1 (also referred to as a rear outrigger device) are arranged so as to be shifted in the front-rear direction. In other words, in the case of this embodiment, the lateral outrigger 10 of one outrigger device 1 and the lateral outrigger 10 of the other outrigger device 1 are arranged adjacent to each other so as to overlap in the front-rear direction. For this reason, the dimension in the vehicle width direction of the horizontal outrigger 10 in each outrigger apparatus 1 can be enlarged to the maximum. That is, in the case where the pair of left and right outrigger devices are not displaced in the front-rear direction (in other words, overlap in the vehicle width direction) like the outrigger devices disclosed in Patent Documents 1 to 3 described above, It is necessary to arrange a pair of outrigger devices on one half and the other half in the vehicle width direction. For this reason, the dimension of the lateral outrigger in the vehicle width direction is limited to a dimension smaller than half of the vehicle width. On the other hand, when the pair of left and right outrigger devices are displaced in the front-rear direction (in other words, do not overlap in the vehicle width direction) as in the present embodiment, the lateral outrigger 10 of the pair of left and right outrigger devices 1 Each dimension can be as close as possible to the vehicle width dimension.
（効果４）アウトリガ支持性能の向上
　本実施形態においては、上記（効果１）～上記（効果３）に基づいて、アウトリガ装置１の張出し幅が限界まで広がる。このため、クレーン作業時の安定性が増すという利益が得られる。 (Effect 4) Improvement of Outrigger Support Performance In the present embodiment, the overhang width of the outrigger device 1 extends to the limit based on the above (Effect 1) to (Effect 3). For this reason, the advantage that the stability at the time of crane work increases is acquired.
　さらに本実施形態に係るアウトリガ装置１は、つぎの（効果５）～（効果７）のような作用・効果も奏する。
（効果５）コンパクトな構成
　リンク機構３０が、３つのパーツからなる簡単な構成なので、縦ジャッキ周辺の占有スペースが小さくコンパクトな構成にできる。 Furthermore, the outrigger device 1 according to the present embodiment also provides the following operations / effects (Effect 5) to (Effect 7).
(Effect 5) Compact configuration Since the link mechanism 30 is a simple configuration composed of three parts, the space occupied around the vertical jack can be reduced and the configuration can be made compact.
（効果６）縦アウトリガを上向きに起立させて格納できるので、縦アウトリガが車体フレーム下方の補機類と干渉しない。このため、架装工事が容易になる。また、縦アウトリガの回転起立は、ジャッキ内箱の収縮動作とともに行われる。すなわち、縦アウトリガの伸縮動作と回転動作とは、縦アウトリガの内部空間に設けられた共通のアクチュエータ（具体的には、ジャッキシリンダ４９）により行われる。このため、特別の動力源を要せずに、自動格納が可能となる。また、縦アウトリガの収縮動作とともに、縦アウトリガの回転動作が行われるため、縦アウトリガの使用状態から格納状態への移行時間が短縮される。 (Effect 6) Since the vertical outrigger can be stowed upward and stored, the vertical outrigger does not interfere with auxiliary equipment below the vehicle body frame. For this reason, bodywork becomes easy. Further, the vertical outrigger is rotated and raised together with the contraction operation of the jack inner box. That is, the expansion / contraction operation and the rotation operation of the vertical outrigger are performed by a common actuator (specifically, the jack cylinder 49) provided in the internal space of the vertical outrigger. For this reason, automatic storage is possible without requiring a special power source. Further, since the vertical outrigger is rotated together with the contraction operation of the vertical outrigger, the transition time from the use state of the vertical outrigger to the storage state is shortened.
（効果７）本実施形態の場合、縦アウトリガ２０が、ジャッキ外箱２１、ジャッキ内箱２２、およびジャッキシリンダ４９（図２参照）により構成される。このような構成は、ジャッキシリンダ４９のみで構成された縦アウトリガと比べて、剛性が高い。このため、作業時におけるクレーンの強度が向上する。 (Effect 7) In the case of this embodiment, the vertical outrigger 20 includes the jack outer box 21, the jack inner box 22, and the jack cylinder 49 (see FIG. 2). Such a configuration is higher in rigidity than a vertical outrigger composed of only the jack cylinder 49. For this reason, the strength of the crane during work is improved.
（第２実施形態）
　図９に基づき第２実施形態のアウトリガ装置を説明する。以下、第２実施形態に係るアウトリガ装置については、図９に示す使用状態に基づいて説明する。 (Second Embodiment)
The outrigger apparatus of 2nd Embodiment is demonstrated based on FIG. Hereinafter, the outrigger device according to the second embodiment will be described based on the use state shown in FIG.
　本実施形態に係るアウトリガ装置は、縦アウトリガとして、第１実施形態におけるジャッキ外箱２１およびジャッキ内箱２２を省略した構成のものを使用する。 The outrigger device according to the present embodiment uses a configuration in which the jack outer box 21 and the jack inner box 22 in the first embodiment are omitted as the vertical outrigger.
　すなわち、本実施形態に係る縦アウトリガは、ジャッキシリンダ５０により構成される。ジャッキシリンダ５０は、シリンダ５１とロッド５２とからなる油圧シリンダで構成される。シリンダ５１内の油室に作動油が給排されることにより、ロッド５２が、シリンダ５１に対して自身の軸方向に移動する。このようなロッド５２の変位にともない、ジャッキシリンダ５０は、自身の軸方向に伸縮する。 That is, the vertical outrigger according to the present embodiment is configured by the jack cylinder 50. The jack cylinder 50 is constituted by a hydraulic cylinder including a cylinder 51 and a rod 52. When the hydraulic oil is supplied to and discharged from the oil chamber in the cylinder 51, the rod 52 moves in the axial direction with respect to the cylinder 51. With such displacement of the rod 52, the jack cylinder 50 expands and contracts in its own axial direction.
　シリンダ５１は、第２ブラケット２４の下方に取付けられる。ロッド５２は、シリンダ５１に挿入される。ロッド５２の下端（先端ともいう。）には、フロート２３が取付けられる。このようなジャッキシリンダ５０は、前述の実施形態１の縦アウトリガ２０と同様の機能を発揮する。 The cylinder 51 is attached below the second bracket 24. The rod 52 is inserted into the cylinder 51. A float 23 is attached to the lower end (also referred to as the tip) of the rod 52. Such a jack cylinder 50 exhibits the same function as the vertical outrigger 20 of the first embodiment.
　第２ブラケット２４は、横アウトリガ１０の横ビーム内箱１２に対しピン２５で取付けられる。アウトリガ装置１の使用状態において、第２ブラケット２４は、横アウトリガ１０に設けられた第１ブラケット１３に２本のピン２５で強固に固定される。アウトリガ装置１の格納動作時は、第２ブラケット２４は、第１ブラケット１３に対して一方のピン２５のみで回動自在に支持される。 The second bracket 24 is attached to the lateral beam inner box 12 of the lateral outrigger 10 with a pin 25. In the use state of the outrigger device 1, the second bracket 24 is firmly fixed to the first bracket 13 provided on the lateral outrigger 10 with two pins 25. During the retracting operation of the outrigger device 1, the second bracket 24 is rotatably supported by only the one pin 25 with respect to the first bracket 13.
　シリンダ５１の上端部には、ガイド部材４１が取付けられる。ガイド部材４１は、ガイド孔４２を有する。この構造は第１実施形態のものと同様である。 A guide member 41 is attached to the upper end of the cylinder 51. The guide member 41 has a guide hole 42. This structure is the same as that of the first embodiment.
　揺動リンク３２の上端部は、第１ピン３５で第１ブラケット１３に枢支される。揺動リンク３２の下端部３２ｂ（図３参照）に挿通された第２ピン３６は、ガイド部材４１のガイド孔４２に挿入される。揺動リンク３２の支点部３２ｃ（図３参照）は、第３ピン３７を介して連結リンク３３に連結される。連結リンク３３の下端には、押し棒３１が連結される。 The upper end of the swing link 32 is pivotally supported by the first bracket 13 with the first pin 35. The second pin 36 inserted through the lower end portion 32 b (see FIG. 3) of the swing link 32 is inserted into the guide hole 42 of the guide member 41. The fulcrum part 32 c (see FIG. 3) of the swing link 32 is connected to the connection link 33 via the third pin 37. A push bar 31 is connected to the lower end of the connection link 33.
　押し棒３１は、伸縮自在であって、全体に長尺に形成された力伝達部材である。押し棒３１は、ジャッキシリンダ５０の車幅方向における内側に、ジャッキシリンダ５０と平行に配置される。具体的には、押し棒３１は、入れ子式の外筒３１ａと内子３１ｂとからなる。 The push rod 31 is a force transmission member that is extendable and formed in a long shape as a whole. The push bar 31 is disposed in parallel with the jack cylinder 50 on the inner side in the vehicle width direction of the jack cylinder 50. Specifically, the push bar 31 includes a telescopic outer cylinder 31a and an inner core 31b.
　内子３１ｂの第１端部（図９の上端部）は、第４ピン３８を介して連結リンク３３に連結される。内子３１ｂの第２端部（図９の下端）は、外筒３１ａの第１端部（図９の上端部）から外筒３１ａに挿入される。外筒３１ａの第２端部は、ロッド５２の下端部に固定される。 The first end portion (upper end portion in FIG. 9) of the inner core 31 b is connected to the connection link 33 via the fourth pin 38. The second end (the lower end in FIG. 9) of the inner core 31b is inserted into the outer cylinder 31a from the first end (the upper end in FIG. 9) of the outer cylinder 31a. The second end portion of the outer cylinder 31 a is fixed to the lower end portion of the rod 52.
　外筒３１ａは、ロッド５２とともに移動可能である。ジャッキシリンダ５０が収縮すると押し棒３１も収縮する。押し棒３１がある程度収縮した以後は、押し棒３１は、連結リンク３３を介して揺動リンク３２を、図９における時計周りの方向に回転させる。また、ジャッキシリンダ５０が伸長すると押し棒３１も伸長して、揺動リンク３２を反時計周りの方向に回転させる。 The outer cylinder 31 a is movable together with the rod 52. When the jack cylinder 50 contracts, the push rod 31 also contracts. After the push rod 31 contracts to some extent, the push rod 31 rotates the swing link 32 in the clockwise direction in FIG. Further, when the jack cylinder 50 is extended, the push rod 31 is also extended, and the swing link 32 is rotated in the counterclockwise direction.
　上記以外の構成は第１実施形態と同様である。したがって、揺動リンク３２が、図９における時計周りの方向に回転するとジャッキシリンダ５０の格納動作が行われる。一方、揺動リンク３２が、図９における反時計周りの方向に回転するとジャッキシリンダ５０の設置動作が行われる。 Other configurations are the same as those in the first embodiment. Therefore, when the swing link 32 rotates in the clockwise direction in FIG. 9, the retracting operation of the jack cylinder 50 is performed. On the other hand, when the swing link 32 rotates counterclockwise in FIG. 9, the jack cylinder 50 is installed.
　本実施形態では、縦アウトリガを油圧式のジャッキシリンダ５０により構成するので、ジャッキ外箱とジャッキ内箱を用いる必要がなく、製造コストを低減できる。さらに、前述した第１実施形態と同様の作用・効果を奏することもできる。 In this embodiment, since the vertical outrigger is constituted by the hydraulic jack cylinder 50, it is not necessary to use a jack outer box and a jack inner box, and the manufacturing cost can be reduced. Furthermore, the same operations and effects as those of the first embodiment described above can be achieved.

For this reason, bodywork becomes easy. In addition, since the vertical outrigger is rotated based on the contraction operation of the jack inner box, a special power source is not required, and the vertical outrigger can be automatically stored.
　アウトリガ装置の参考例２として、参考例１において、リンク機構が、ジャッキ外箱に上下動可能に取付けられた押し棒と、一端を横ビーム内箱の先端部にピン連結するとともに、他端をジャッキ外箱に対し側方回動力を伝達可能に設けた揺動リンクと、押し棒の上端と揺動リンクとを連結する連結リンクとを有してもよい。 As a reference example 2 of the outrigger device, in the reference example 1, the link mechanism has a push rod attached to the jack outer box so as to be movable up and down, one end is pin-connected to the tip of the horizontal beam inner box, and the other end is connected.
