Description

【０００１】
【発明の属する技術分野】
本発明は、開口部内の重量物の吊り上げ作業に用いられる揚重機を取り付けるための重量物揚重雇に関する。
【０００２】
【従来の技術】
クレーン等が利用できない場所で重量物の吊り上げ作業を行う場合、例えば特開平６−２２７７８７号公報に開示されているように、４本の支柱を備えた櫓型の揚重雇を重量物の上方に設置して、この揚重雇に取り付けたチェーンブロック等の揚重機によって重量物を吊り上げるという手法が一般的である。だが、このような櫓型の揚重雇は多くの部品を必要とするためコスト高になるという不具合があり、また、広い設置スペースが必要なため狭い場所では適用できないという不具合があった。
【０００３】
これに対して、特開平１０−３２４４８６号公報に開示されている揚重雇は、重量物を引き上げる開口部の近傍の床面に、一対の支柱を立設すると共に、これら支柱の上端部どうしを梁部にて連結し、この梁部に取り付けた揚重機によって開口部内の重量物を吊り上げるというものなので、部品点数の削減によりコストダウンが図れ、また、さほど広い設置スペースを必要としないため省スペース化も図れるという利点がある。
【０００４】
【発明が解決しようとする課題】
しかしながら、上述した特開平１０−３２４４８６号公報記載の重量物揚重雇は、揚重機を取り付ける際の作業員の肉体的負担が大きくて、安全性にも難があった。すなわち、かかる従来の重量物揚重雇では、その上部に設置されている梁部の高さ位置まで、チェーンブロック等の揚重機を人力にて持ち上げたうえで、この揚重機を梁部に取り付けねばならないが、約１００ｋｇもあるチェーンブロック等を持ち上げる作業は容易でないばかりか、開口部の近傍での作業となるため作業員が誤って開口部内へ転落する危険性がある。
【０００５】
本発明はこのような従来技術の課題に鑑みてなされたもので、その第１の目的は、設置作業や揚重機の取付作業で作業員の肉体的負担が軽減できて安全性も確保できる、重量物揚重雇を提供することにある。
【０００６】
【課題を解決するための手段】
上述した目的を達成するため、本発明は、開口部近傍の床面に固定される固定部材と、この固定部材に下端部が保持されて、前記床面上で傾倒した姿勢から鉛直面に沿って前記開口部側へ起立可能な一対の支柱と、これら一対の支柱の上端部どうしを連結する梁部とを備え、前記梁部に取り付けた揚重機にて前記開口部内の重量物を吊り上げ可能となす重量物揚重雇において、前記床面上に立設される起立柱と、この起立柱の上端部に取り付けられる巻上げ機と、前記梁部に繋着されて前記巻上げ機に巻き取られる起立用索とを有する起立装置と、前記床面上に載置されて傾倒姿勢の前記支柱を支える支え体と、この支え体と前記支柱との間に介在されて両者の間隔が変更可能な調整部材とを有する支え手段を備え、この支え手段により前記梁部を、前記床面上の複数の高さ位置に選択的に保持可能とすると共に、前記起立柱が、前記床面に固定される下端部から斜め上方へ延びる柱状部を有し、この柱状部を前記開口部側へ傾けて起立させることとした。
【０００７】
このような構成の重量物揚重雇では、支柱を床面上に寝かせた状態にして梁部に揚重機を取り付けた後、起立装置の巻上げ機にて起立用索を巻き取りながら支柱を開口部側へ起立させることができるので、重い揚重機の取付作業を床面近くで行うことができて作業員の肉体的負担が大幅に軽減でき、安全性も高まる。
【０００８】
また、かかる構成において、前記起立柱が、前記床面に固定される下端部から斜め上方へ延びる柱状部を有し、この柱状部を前記開口部側へ傾けて起立させておけば、柱状部に取り付けた巻上げ機を駆動させて支柱を起立させる際に、この巻上げ機と支柱や梁部との干渉を確実に回避することができる。
【０００９】
また、前記起立柱の下端部を前記固定部材に固定すれば、前記床面に新たな固定用の部材を付設する必要がなくなるので、設置作業の煩雑化が回避できる。
【００１０】
また、前記床面上に載置されて傾倒姿勢の前記支柱を支える支え体と、この支え体と前記支柱との間に介在されて両者の間隔が変更可能な調整部材とを有する支え手段を備え、この支え手段により前記梁部を、前記床面上の複数の高さ位置に選択的に保持可能とすれば、床面近くで揚重機を梁部に取り付ける際に、その取付作業に適した所望の高さ位置に梁部を保持しておくことができるので、揚重機の取付作業を一層効率よく行うことができる。
【００１１】
【発明の実施の形態】
以下、本発明による重量物揚重雇の一実施形態例を図１〜図６を参照しつつ説明する。ただし、図１は設置した該揚重雇の起立前の状態を示す側面図、図２は設置した該揚重雇の起立前の状態を示す斜視図、図３は該揚重雇の梁部に揚重機を取り付ける際の様子を示す側面図、図４は該揚重雇の支柱を起立させる際の様子を示す側面図、図５は該揚重雇の設置完了状態を示す側面図、図６は設置完了した該揚重雇で重量物を吊り上げている様子を示す斜視図である。
【００１２】
これらの図に示す重量物揚重雇は、開口部１５の近傍の床面１６にベース３を介して固定された固定部材４と、この固定部材４に下端部が保持されて、床面１６上で傾倒した姿勢から鉛直面に沿って開口部１５側へ起立可能な一対の支柱５と、各支柱５の上端部どうしを連結する梁部６と、各支柱５を起立させるための一対の起立装置１と、揚重機を取り付ける際に梁部６を床面１６から所定の高さ位置に保持するための一対の支え手段１０とによって概略構成されている。そして、揚重機である電動チェーンブロック８を梁部６に取り付けた後、起立装置１により支柱５を起立させて電動チェーンブロック８を所定位置に配置させれば、この揚重雇は床面１６上での設置が完了し、設置完了後には電動チェーンブロック８によって開口部１５内の重量物を吊り上げることが可能となる。
【００１３】
なお、支柱５の下端部を保持している固定部材４はベース３に取り付けられており、このベース３はアンカーボルト３ａを用いて床面１６に固定されている。
【００１４】
また、前記起立装置１は、床面１６上に立設された起立柱１１と、この起立柱１１の上端部に取り付けられた手動チェーンブロック等の小型の巻上げ機１２ａと、一端部が梁部６に繋着されて他端側が巻上げ機１２ａに巻き取られる起立用索１２ｂとによって構成されている。起立柱１１はその下端部１１ｂから柱状部１１ａを斜め上方へ延ばした略く字形の外観を呈し、下端部１１ｂを固定部材４に固定することにより、柱状部１１ａを開口部１５側へ傾けて起立させている。
【００１５】
また、前記支え手段１０は、床面１６上に載置されて傾倒姿勢の支柱５の長手方向中間部を支える支え体１０ａと、この支え体１０ａと支柱５との間に介在されて両者の間隔が変更可能な調整部材１０ｂと、この調整部材１０ｂを支柱５に取り付けているボルト等の締結具１０ｃとによって構成されている。つまり、床面１６上の支え体１０ａが調整部材１０ｂの複数箇所を選択的に係止でき、その係止位置に応じて支え体１０ａに支えられる支柱５の傾倒角度が僅かずつ変化するようになっているので、この支え手段１０により、梁部６を床面１６上の複数の高さ位置に選択的に保持することができる。
【００１６】
このように構成される重量物揚重雇は、まず、各支柱５の下端部を、ベース３を介して床面１６に固定されている固定部材４に取り付けて、各支柱５の上端部どうしを梁部６にて連結した後、支え手段１０により各支柱５を所望の傾倒角度に保ったまま、梁部６に電動チェーンブロック８を取り付ける。具体的には、図３に示すように、網台車１３内に収納した電動チェーンブロック８を床面１６上で移動させて、このチェーンブロック８を梁部６に装着されている吊り金具７に取り付けるので、この吊り金具７が床面１６上の所望の高さ位置に配置されるように支柱５の傾倒角度を設定し、その傾倒角度を保って支え体１０ａにて支柱５を支えておけば、重い電動チェーンブロック８を極めて簡単に梁部６に取り付けることができる。
【００１７】
そして、梁部６に電動チェーンブロック８を取り付けた後、起立柱１１の下端部１１ｂを前記固定部材４に固定して、柱状部１１ａを開口部１５側へ斜めに起立させ、この柱状部１１ａの上端に巻上げ機１２ａを取り付けることにより、起立装置１を組み付ける。しかる後、図４に示すように、各起立装置１の巻上げ機１２ａにて起立用索１２ｂを巻き取っていくことにより、各支柱５を破線Ａの状態から矢印Ｂに沿って徐々に起立させていき、梁部６が開口部１５側へせり出す所定位置まで各支柱５を起立させる。また、図５に示すように、固定ベース９により床面１６に固定されている支柱保持材１７を介して、起立させた支柱５と床面１６とを連結しておく。
【００１８】
こうして重量物揚重雇を開口部１５近傍の床面１６上に設置する作業が完了したなら、梁部６に取り付けられている電動チェーンブロック８を駆動させて、開口部１５内の重量物をチェーン８ａにより吊り上げることができる。
【００１９】
このように本実施形態例によれば、重量物揚重雇に起立装置１が付設してあるので、作業員は小型の巻上げ機１２ａを駆動させることにより、重い電動チェーンブロック８が取り付けてある梁部６と共に一対の支柱５を容易に起立させることができる。それゆえ、予め支柱５を寝かせた状態にしておき、床面１６近くで電動チェーンブロック８を梁部６に取り付ければよくなり、その取付作業が簡単かつ安全に行えるようになっている。しかも、本実施形態例では支え手段１０により、床面１６近くで電動チェーンブロック８を取り付ける作業に適した所望の高さ位置に梁部６を保持しておくことができるので、電動チェーンブロック８の取付作業が極めて効率よく行え、作業員の肉体的負担を大幅に軽減することができる。
【００２０】
なお、巻上げ機１２ａで起立用索１２ｂを巻き取る際に起立柱１１は反力により図１，４の時計回り方向へ引っ張られるが、起立柱１１の下端部１１ｂに当接する床面１６が該反力を受け止めるので負荷の応力集中は回避でき、よって起立柱１１は比較的軽強度の軽い部材となすことができる。
【００２１】
また、本実施形態例では、起立柱１１の下端部１１ｂを、支柱５の下端部を保持している固定部材４に固定すればよく、床面１６に新たな固定用の部材を付設する必要がないので、設置作業の煩雑化が回避されている。さらにまた、この起立柱１１は、その柱状部１１ａを開口部１５側へ傾けて起立させるので、柱状部１１ａに取り付けた巻上げ機１２ａを駆動させて支柱５を起立させる際に、巻上げ機１２ａが支柱５や梁部６に干渉して作業性を損なう心配はない。
【００２２】
なお、上述した重量物揚重雇を、図６に示すように開口部１５を挟んで対向させた状態で２台設置すれば、エスカレータフレーム１４のような大型の重量物の揚重作業も円滑に行える。
【００２３】
【発明の効果】
本発明は以上説明したような形態で実施され、以下に記載されるような効果を奏する。
【００２４】
支柱を床面上に寝かせた状態にして梁部に揚重機を取り付けた後、起立装置の巻上げ機にて起立用索を巻き取りながら支柱を開口部側へ起立させることができるので、重い揚重機の取付作業を床面近くで簡単に行うことができて、作業員の肉体的負担が大幅に軽減できると共に安全性も高まる。
【００２５】
また、支え手段により梁部を床面上の複数の高さ位置に選択的に保持可能としておけば、床面近くで揚重機を梁部に取り付ける際に、その取付作業に適した所望の高さ位置に梁部を保持しておくこができるので、揚重機の取付作業を一層効率よく行うことができる。

[0002]
[Prior art]
When a heavy load is lifted in a place where a crane or the like cannot be used, for example, as disclosed in Japanese Patent Laid-Open No. 6-227787, a saddle type lifter with four columns is placed above the heavy load. It is common to use a lifting machine such as a chain block that is installed in the lift and lifts heavy objects. However, such a saddle-type heavy lifter requires a lot of parts and is expensive, and it requires a large installation space and cannot be applied in a narrow place.
[0003]
On the other hand, in the lifting work disclosed in Japanese Patent Laid-Open No. 10-324486, a pair of pillars are erected on the floor near the opening for lifting heavy objects, and the upper ends of these pillars are connected to each other. Are connected to each other by a beam, and heavy objects in the opening are lifted by a lifting machine attached to the beam. Therefore, the cost can be reduced by reducing the number of parts, and a large installation space is not required. There is an advantage that space can be achieved.
[0004]
[Problems to be solved by the invention]
However, the heavy lifting work described in Japanese Patent Laid-Open No. 10-324486 described above has a heavy physical burden on the worker when installing the lifting machine, and has a difficulty in safety. That is, in such conventional heavy lifting equipment, a lifting machine such as a chain block is manually lifted up to the height of the beam installed at the top, and this lifting machine is attached to the beam. It must be done, but not only is it difficult to lift a chain block that weighs about 100 kg, but there is a risk that an operator will accidentally fall into the opening because it is in the vicinity of the opening.
[0005]
The present invention has been made in view of such problems of the prior art, and the first object thereof is to reduce the physical burden on the worker in the installation work and the lifting machine mounting work, and to ensure safety. The purpose is to provide heavy lifting .
[0006]
[Means for Solving the Problems]
In order to achieve the above-described object, the present invention provides a fixing member that is fixed to the floor surface near the opening, and a lower end portion that is held by the fixing member, and is tilted on the floor surface along the vertical plane. A pair of struts that can stand up to the opening side, and a beam portion that connects the upper end portions of the pair of struts, and a heavy machine attached to the beam portion can lift heavy objects in the opening portion In the heavy lifting work, the upright pillar erected on the floor surface, the hoisting machine attached to the upper end of the uprighting pillar, and the beam part connected to the hoisting machine. A standing device having a standing rope, a support body that is placed on the floor surface and supports the support column in a tilted posture, and is interposed between the support body and the support column so that the distance between them can be changed. A support means having an adjustment member, and the support means Part of, as well as the selectively can be stored in the plurality of height positions on the floor, the upright pillar has a columnar portion extending obliquely upward from the lower end portion fixed to the floor, the columnar The part was inclined to the opening part side and stood up .
[0007]
In the heavy lifting work with such a structure, after placing the lifting equipment on the beam with the support on the floor, open the support while winding up the standing rope with the hoist of the standing device Since it can be erected to the part side, heavy lifting equipment can be installed near the floor, so that the physical burden on the worker can be greatly reduced and safety is improved.
[0008]
Further, in this configuration, if the upright column has a columnar portion extending obliquely upward from a lower end portion fixed to the floor surface, and the columnar portion is tilted toward the opening side, the columnar portion When driving the hoisting machine attached to the stand to erect the column, it is possible to reliably avoid interference between the hoisting machine and the column or beam.
[0009]
Further, if the lower end portion of the upright pillar is fixed to the fixing member, it is not necessary to attach a new fixing member to the floor surface, so that complication of installation work can be avoided.
[0010]
Further, a support means having a support body that is placed on the floor surface and supports the support column in a tilted posture, and an adjustment member that is interposed between the support body and the support column and that can change the distance between the support member and the support member. If the beam portion can be selectively held at a plurality of height positions on the floor surface by the support means, it is suitable for the mounting work when the lifting machine is attached to the beam portion near the floor surface. Since the beam portion can be held at a desired height position, the lifting machine can be attached more efficiently.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of heavy lifting according to the present invention will be described with reference to FIGS. However, FIG. 1 is a side view showing a state before the lifted worker is standing, FIG. 2 is a perspective view showing a state before the lifted worker is standing, and FIG. 3 is a beam portion of the lifted worker. FIG. 4 is a side view showing a state when the lifting work strut is erected, FIG. 5 is a side view showing the installation completion state of the lifting work, and FIG. 6 is a perspective view showing a state in which a heavy object is lifted by the lifting work that has been completed.
[0012]
In the heavy lifting shown in these drawings, the fixing member 4 fixed to the floor surface 16 near the opening 15 via the base 3 and the lower end portion of the fixing member 4 are held, and the floor surface 16 A pair of pillars 5 that can stand up to the opening 15 side along the vertical plane from the tilted position above, a beam part 6 that connects the upper ends of the pillars 5, and a pair for standing up the pillars 5 The upright device 1 and a pair of support means 10 for holding the beam portion 6 at a predetermined height from the floor surface 16 when the lifting machine is attached are schematically configured. And after attaching the electric chain block 8 which is a lifting machine to the beam part 6, if the support | pillar 5 is stood up by the standing device 1 and the electric chain block 8 is arrange | positioned in a predetermined position, this lifting employment will be the floor 16 The above installation is completed, and after the installation is completed, the electric chain block 8 can lift the heavy object in the opening 15.
[0013]
In addition, the fixing member 4 holding the lower end portion of the column 5 is attached to the base 3, and the base 3 is fixed to the floor surface 16 using anchor bolts 3 a.
[0014]
The standing device 1 includes a standing column 11 standing on the floor 16, a small hoisting machine 12a such as a manual chain block attached to the upper end of the standing column 11, and a beam portion at one end. 6 and the other end side is constituted by a standing rope 12b wound up by a winder 12a. The upright column 11 has a substantially square-shaped appearance in which the columnar portion 11a extends obliquely upward from the lower end portion 11b. By fixing the lower end portion 11b to the fixing member 4, the columnar portion 11a is inclined toward the opening 15 side. Standing up.
[0015]
The support means 10 is placed on the floor 16 and supports the intermediate portion in the longitudinal direction of the support column 5 in a tilted posture, and is interposed between the support member 10a and the support column 5 to The adjustment member 10b can change the interval, and a fastener 10c such as a bolt that attaches the adjustment member 10b to the column 5 is configured. That is, the support body 10a on the floor surface 16 can selectively lock a plurality of locations of the adjustment member 10b, and the tilt angle of the support column 5 supported by the support body 10a changes little by little according to the locking position. Therefore, the beam means 6 can be selectively held at a plurality of height positions on the floor surface 16 by the supporting means 10.
[0016]
In the heavy lifting construction configured as described above, first, the lower end portion of each support column 5 is attached to the fixing member 4 fixed to the floor 16 via the base 3, and the upper end portions of the support columns 5 are connected to each other. Then, the electric chain block 8 is attached to the beam portion 6 while the support columns 10 are kept at a desired tilt angle by the support means 10. Specifically, as shown in FIG. 3, the electric chain block 8 housed in the net carriage 13 is moved on the floor surface 16, and the chain block 8 is attached to the hanging bracket 7 attached to the beam portion 6. The tilt angle of the column 5 is set so that the hanging bracket 7 is arranged at a desired height position on the floor surface 16 and the column 5 is supported by the support body 10a while maintaining the tilt angle. In this case, the heavy electric chain block 8 can be attached to the beam portion 6 very easily.
[0017]
And after attaching the electric chain block 8 to the beam part 6, the lower end part 11b of the standing pillar 11 is fixed to the said fixing member 4, and the columnar part 11a is stood up diagonally to the opening part 15 side, This columnar part 11a The upright device 1 is assembled by attaching the hoisting machine 12a to the upper end. Thereafter, as shown in FIG. 4, each column 5 is gradually raised from the state of the broken line A along the arrow B by winding up the standing rope 12 b with the hoisting machine 12 a of each standing device 1. Each column 5 is raised up to a predetermined position where the beam 6 protrudes toward the opening 15. Further, as shown in FIG. 5, the upright column 5 and the floor surface 16 are connected to each other through a column holding member 17 fixed to the floor surface 16 by the fixed base 9.
[0018]
In this way, when the work of installing the heavy lifting equipment on the floor 16 near the opening 15 is completed, the electric chain block 8 attached to the beam 6 is driven to remove the heavy goods in the opening 15. It can be lifted by the chain 8a.
[0019]
As described above, according to the present embodiment, since the standing device 1 is attached to heavy lifting, the worker drives the small hoist 12a to attach the heavy electric chain block 8. A pair of support pillars 5 can be easily erected together with the beam portion 6. Therefore, it is only necessary to place the support column 5 in advance and attach the electric chain block 8 to the beam portion 6 near the floor surface 16, so that the attaching operation can be performed easily and safely. In addition, in this embodiment, the beam means 6 can be held at a desired height position suitable for the work of attaching the electric chain block 8 near the floor surface 16 by the support means 10. Can be carried out extremely efficiently, and the physical burden on the worker can be greatly reduced.
[0020]
When the standing rope 12b is wound up by the hoisting machine 12a, the standing pillar 11 is pulled in the clockwise direction in FIGS. 1 and 4 by the reaction force, but the floor surface 16 in contact with the lower end portion 11b of the standing pillar 11 is Since the reaction force is received, the stress concentration of the load can be avoided, so that the upright column 11 can be a light member having a relatively light strength.
[0021]
In this embodiment, the lower end portion 11 b of the upright column 11 may be fixed to the fixing member 4 holding the lower end portion of the column 5, and a new fixing member needs to be attached to the floor surface 16. Therefore, complication of installation work is avoided. Furthermore, since this standing pillar 11 stands by tilting its columnar part 11a toward the opening 15 side, when the hoisting machine 12a is driven to drive the hoisting machine 12a attached to the columnar part 11a, the hoisting machine 12a There is no worry of impairing workability by interfering with the column 5 or the beam portion 6.
[0022]
In addition, if the above-mentioned heavy lifting equipment is installed with two openings facing each other across the opening 15 as shown in FIG. 6, the lifting work of a large heavy object such as the escalator frame 14 can be carried out smoothly. Can be done.
[0023]
【The invention's effect】
The present invention is implemented in the form as described above, and has the effects described below.
[0024]
After attaching the lifting machine to the beam with the support placed on the floor, the support can be raised to the opening while winding up the standing rope with the hoisting machine of the standing device. The installation work of heavy machinery can be easily performed near the floor, so that the physical burden on the worker can be greatly reduced and the safety is improved.
[0025]
In addition, if the beam part can be selectively held at a plurality of height positions on the floor surface by the supporting means, when the lifting machine is attached to the beam part near the floor surface, a desired height suitable for the attachment work is obtained. Since the beam portion can be held in this position, the lifting machine can be mounted more efficiently.
