以下、図１乃至図９を参照しつつ、本発明の非限定の実施形態と、これに内包又は関連した複数の特徴について説明する。当業者は、各実施形態及び／又は各特徴を組み合わせることができ、また、この組み合わせによる相乗効果も理解可能である。個別の特徴は、例えば、図面に図示された台車及び／又は運搬方法にのみ有効であるものではなく、不図示の他の様々な台車及び／又は運搬方法にも通用する普遍的な特徴である。 Hereinafter, a non-limiting embodiment of the present invention and a plurality of features included or related to the same will be described with reference to FIGS. 1 to 9. Those skilled in the art can combine the embodiments and/or the features, and can understand the synergistic effect of the combination. The individual features are, for example, universal features that are not only valid for the trolleys and/or transport methods illustrated in the drawings, but also for various other trolleys and/or transport methods not shown. ..

図１に示すように、牽引具９を介して荷役車両１００に対して台車１が連結される。荷役車両１００は、これに限ったものではないが、例えば、フォークリフトであり、昇降装置１０１と昇降装置１０１に取り付けられた昇降体１０２を有する。本明細書で述べる前後方向は図１に示したとおりであり、荷役車両１００に関する前後方向と台車１に関する前後方向が反対である。荷役車両１００が後進することにより台車１が前進し、荷役車両１００が前進することにより台車１が後進する。牽引具９に関する前後方向と台車１に関する前後方向は同一である。なお、以下、荷役車両１００をフォークリフトとして、また昇降体１０２をフォークとして説明する。 As shown in FIG. 1, the truck 1 is connected to the cargo handling vehicle 100 via a towing tool 9. Although not limited to this, the cargo handling vehicle 100 is, for example, a forklift, and includes a lifting device 101 and a lifting body 102 attached to the lifting device 101. The front-back direction described in this specification is as shown in FIG. 1, and the front-back direction regarding the cargo handling vehicle 100 and the front-back direction regarding the carriage 1 are opposite. When the cargo handling vehicle 100 moves backward, the truck 1 moves forward, and when the cargo handling vehicle 100 moves forward, the truck 1 moves backward. The front-rear direction regarding the tow tool 9 and the front-rear direction regarding the carriage 1 are the same. Hereinafter, the cargo handling vehicle 100 will be described as a forklift, and the lifting body 102 will be described as a fork.

後述のように、フォークリフト１００のフォーク１０２に対して牽引具９を簡単に装着及び脱着することができ、また、牽引具９と台車１の連結も容易に行うことができる。従って、フォークリフト１００、牽引具９、及び台車１の連結に要する時間や労力は大きくない。フォークリフト１００と台車１の間に牽引具９分の空間が確保され、台車１上に重量物２００を載置する時や台車１上から重量物２００を下ろす時の空間的な制約が低減される。なお、牽引具９の前後長Ｌ９よりも台車１の前後長Ｌ１が大きく、重量物２００として前後方向に長い長尺物の搬送にも対応可能である。 As will be described later, the tow tool 9 can be easily attached to and detached from the fork 102 of the forklift 100, and the tow tool 9 and the carriage 1 can be easily connected. Therefore, the time and labor required to connect the forklift 100, the towing tool 9, and the truck 1 are not great. A space for 9 minutes of the towing tool is secured between the forklift 100 and the trolley 1, and spatial restrictions when the heavy load 200 is placed on the trolley 1 or when the heavy load 200 is unloaded from the trolley 1 are reduced. .. The front-rear length L1 of the trolley 1 is larger than the front-rear length L9 of the towing tool 9, and it is possible to support the conveyance of a long object as a heavy load 200 that is long in the front-back direction.

図２及び図３に示すように、フォークリフト１００と牽引具９が連結される。具体的には、フォークリフト１００のフォーク１０２の前方に向けて延びる左右に隣接した一対の平板部１０２ａが牽引具９の鞘部９８内に挿入される。続いて、鞘部９８の左右側壁に同軸配置された孔にピン９５が挿入され、これにより、鞘部９８とフォーク１０２の分離が阻止される。フォークリフト１００の昇降装置１０１がフォーク１０２の高さを変更することによりフォーク１０２に連結した牽引具９の高さも適切に設定することができる。なお、本明細書で述べる左右方向は図４に示したとおりであり、前後方向に直交する。 As shown in FIGS. 2 and 3, the forklift 100 and the tow tool 9 are connected. Specifically, a pair of right and left flat plate portions 102 a that extend toward the front of the fork 102 of the forklift 100 and are adjacent to each other are inserted into the sheath portion 98 of the towing tool 9. Subsequently, the pin 95 is inserted into the holes coaxially arranged on the left and right sidewalls of the sheath 98, thereby preventing the sheath 98 and the fork 102 from being separated. By the elevation device 101 of the forklift 100 changing the height of the fork 102, the height of the tow tool 9 connected to the fork 102 can also be appropriately set. The left-right direction described in this specification is as shown in FIG. 4, and is orthogonal to the front-back direction.

台車１は、牽引具９との連結のために用いられる連結部５を有する。牽引具９は、連結部５が連結される被連結部９９を有する。連結部５が鉛直方向に延びる連結突起である場合、被連結部９９が鉛直方向に延びる孔である。連結部５が鉛直方向に延びる孔である場合、被連結部９９が鉛直方向に延びる連結突起である。 The trolley 1 has a connecting portion 5 used for connecting with the pulling tool 9. The tow tool 9 has a connected portion 99 to which the connecting portion 5 is connected. When the connecting portion 5 is a vertically extending connecting protrusion, the connected portion 99 is a vertically extending hole. When the connecting portion 5 is a hole extending in the vertical direction, the connected portion 99 is a connecting protrusion extending in the vertical direction.

台車１と牽引具９の連結のためにフォークリフト１００を用いることができる。例えば、フォークリフト１００の作動に基づいて、（連結部５としての）鉛直方向下方に延びる連結突起の下方に、（被連結部９９としての）牽引具９の孔を配置する。続いて、フォークリフト１００の昇降装置１０１の作動に基づいて牽引具９を上昇させ、台車１側の連結突起を牽引具９の孔に挿入する。牽引具９は、台車１の連結部５に関する回転軸回りに回動可能である（図４参照）。１８０°を超える角度範囲にて牽引具９が台車１の連結部５回りに回動し、フォークリフト１００による台車１の引き回しの自由度が高められる。なお、２以上の台車１のために共通の牽引具９を用いることもできる。 A forklift 100 can be used to connect the carriage 1 and the towing tool 9. For example, based on the operation of the forklift 100, the hole of the towing tool 9 (as the connected portion 99) is arranged below the connecting protrusion that extends downward in the vertical direction (as the connecting portion 5). Then, the towing tool 9 is raised based on the operation of the lifting/lowering device 101 of the forklift 100, and the connecting projection on the side of the carriage 1 is inserted into the hole of the towing tool 9. The tow tool 9 is rotatable about a rotation axis of the connecting portion 5 of the carriage 1 (see FIG. 4). The tractor 9 rotates around the connecting portion 5 of the dolly 1 in an angle range of more than 180°, and the degree of freedom in routing the dolly 1 by the forklift 100 is increased. A common traction tool 9 can be used for two or more carts 1.

図４に示すように、台車１は、上述の連結部５が設けられた第１連結部材２１と、複数の車輪８により接地面上に支持された本体部７を有する２以上の台車部１１，１２と、第１連結部材２１との間に２以上の台車部１１，１２を挟むように設けられる第２連結部材２２を有し、台車１に関する前後方向において前方から後方に向けて第１連結部材２１、台車部１１，１２、及び第２連結部材２２がこの順で配置される。２以上の台車部１１，１２に含まれる各台車部１１，１２が、連結位置の調整が可能な態様で第１連結部材２１に連結し、同様、連結位置の調整が可能な態様で第２連結部材２２に連結する。台車部として２つの台車部１１，１２が図示されるが、３つ以上の台車部が共通の連結部材２１，２２に連結する形態も想定される。なお、以下、説明の便宜上、２つの台車部１１，１２の一方の台車部１１を第１台車部と呼び、他方の台車部１２を第２台車部１２と呼ぶ場合がある。台車部１１，１２の形状等によっては第２連結部材２２が省略され、又は、本開示とは異なる態様で台車部１１，１２が左右方向にて連結する態様も想定される。 As shown in FIG. 4, the trolley|bogie 1 has two or more trolley|bogie parts 11 which have the 1st connection member 21 in which the above-mentioned connection part 5 was provided, and the main-body part 7 supported by the some wheel 8 on the ground contact surface. , 12 and the first connecting member 21 are provided with a second connecting member 22 provided so as to sandwich two or more bogie portions 11 and 12, and in the front-rear direction with respect to the bogie 1, the first connecting member 22 extends from the front to the rear. The connecting member 21, the truck parts 11 and 12, and the second connecting member 22 are arranged in this order. Each of the trolley parts 11 and 12 included in the two or more trolley parts 11 and 12 is coupled to the first coupling member 21 in a manner in which the coupling position can be adjusted, and similarly, the second in a manner in which the coupling position can be adjusted. It connects with the connecting member 22. Although two bogie parts 11 and 12 are shown as bogie parts, a configuration in which three or more bogie parts are connected to the common connecting members 21 and 22 is also envisioned. For convenience of description, one of the two carriages 11 and 12 may be referred to as a first carriage, and the other carriage 12 may be referred to as a second carriage 12. The second connecting member 22 may be omitted depending on the shapes of the carriages 11 and 12, or the carriages 11 and 12 may be connected in the left-right direction in a manner different from the present disclosure.

図４及び図５に示すように、各台車部１１，１２の本体部７は、前後方向に長尺であり、重量物２００（図１参照）が載置される上面７ｊと、車輪８が取り付けられる下面７ｆを有する。本体部７は、例えば、複数のＨ形鋼から構築され、１０ｔ又は１５ｔ又は２０ｔを超える重量の重量物２００から受ける荷重に耐えることができる。場合によっては、本体部７は、１ｔ又は１．５ｔ又は２ｔを超える重量を有する。Ｈ形鋼の溶接により構築される本体部７の上面７ｊの直上に重量物２００が載置される場合に加えて、本体部７の上面７ｊの直上に枕木が置かれ、枕木の上に重量物２００が載置される態様も想定される。車輪８は、高い耐荷重性能を有するように構成され、例えば、車輪８のタイヤ材としてウレタンゴムといったゴムが採用される。好適には、車輪８は、車輪８のタイヤ材の摩耗や劣化の進行の程度に応じて１つ又は複数単位で交換可能である。重量物２００としては、自動車の組立工場に配備される多様な種類の据え置き型の機械設備や建設工事現場で運搬される資材が例示されるが、これに限られるべきものではない。 As shown in FIGS. 4 and 5, the main body 7 of each of the trucks 11 and 12 is long in the front-rear direction, and the upper surface 7j on which the heavy object 200 (see FIG. 1) is placed and the wheels 8 are provided. It has a bottom surface 7f that is attached. The main body part 7 is constructed of, for example, a plurality of H-section steels and can bear a load received from the heavy object 200 having a weight of more than 10t or 15t or 20t. In some cases, the body 7 has a weight of more than 1t or 1.5t or 2t. In addition to the case where the heavy object 200 is placed directly on the upper surface 7j of the main body 7 constructed by welding of H-section steel, the sleeper is placed directly on the upper surface 7j of the main body 7 and the weight is placed on the sleeper. A mode in which the object 200 is placed is also envisioned. The wheel 8 is configured to have a high load bearing performance, and, for example, rubber such as urethane rubber is adopted as a tire material of the wheel 8. Preferably, the wheel 8 is replaceable in one or more units depending on the degree of progress of wear and deterioration of the tire material of the wheel 8. Examples of the heavy load 200 include stationary machinery and equipment of various types deployed in an automobile assembly plant and materials transported at a construction site, but the heavy load 200 is not limited thereto.

各台車部１１，１２は、第１連結部材２１から離間する方向において間隔を空けてこの順で配置された第１及び第２車輪部３１，３２を有する。各台車部１１，１２の第１車輪部３１には１以上の又は少なくとも２つの車輪が含まれ、図４の場合、左右方向に配置された２つ車輪ペア（合計４つの車輪）が含まれる。各台車部１１，１２の第２車輪部３２には１以上の又は少なくとも２つの車輪が含まれ、図４の場合、左右方向に一定ピッチで配置された６つの車輪が含まれる。このような場合、本体部７上に載置される重量物２００及び本体部７自体の合計荷重を複数の車輪８で分担して受けることができる。 Each trolley|bogie part 11, 12 has the 1st and 2nd wheel part 31, 32 arrange|positioned in this order at intervals in the direction which separates from the 1st connection member 21. One or more or at least two wheels are included in the first wheel part 31 of each of the bogie parts 11 and 12, and in the case of FIG. 4, two wheel pairs arranged in the left-right direction (four wheels in total) are included. ..
