Description

本発明は、親綱装置に関する。   The present invention relates to a master rope device.

特許文献1に記載の従来技術では、トラックの荷台に近接した位置に設けた支柱間に親綱を掛け渡す技術が開示されている。   In the prior art described in Patent Document 1, a technique is disclosed in which a master rope is hung between struts provided at positions close to a truck bed.

特開2000−210389号公報JP 2000-210389A

しかし、上述の特許文献1に記載の従来技術では、支柱をトラックに併設する必要があるため、別途設置スペースが必要になるという問題がある。また、トラックの荷台上で作業を行なう毎に支柱を設置する必要があるとともに、作業終了後には支柱を片付ける必要があり作業に手間がかかる。一方、支柱を設置したままの状態では他のトラック走行の邪魔になるという問題がある。   However, in the prior art described in Patent Document 1 described above, there is a problem in that a separate installation space is required because it is necessary to install a support post on the track. In addition, it is necessary to install a support column every time work is performed on the truck bed, and it is necessary to clean up the support column after the work is completed. On the other hand, there is a problem that when the support is installed, it disturbs other trucks.

一方、親綱を建物の天井壁に固定することが考えられるが、親綱の高さ調整ができず、親綱が天井に近い位置にあると、命綱が掛け難いという問題がある。一方、親綱が天井から離れた位置にあると、例えば荷台が高い大型のトラックが通過する際に、親綱がトラックに接触して走行の邪魔になるという問題がある。   On the other hand, it is conceivable to fix the master rope to the ceiling wall of the building, but the height of the master rope cannot be adjusted, and there is a problem that it is difficult to hang the lifeline if the master rope is close to the ceiling. On the other hand, when the master rope is at a position away from the ceiling, for example, when a large truck with a high loading platform passes, there is a problem that the master rope contacts the truck and obstructs the traveling.

そこで本発明は、親綱の高さ調整ができ、しかも支柱の設置スペースが必要とならず、トラックの走行の邪魔にもならない親綱装置を提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide a master rope device that can adjust the height of the master rope, does not require a space for installing a support, and does not obstruct the traveling of a truck.

前記課題を解決するために、請求項1に記載された発明は、転落防止用の命綱を掛ける親綱と、建物の天井壁に設けた親綱の一端を固定する固定部と親綱の他端を固定する可動取付部と、可動取付部を水平方向に移動させる駆動手段とを備え、駆動手段は可動取付部を水平方向に移動して親綱を上下動させることを特徴とする。   In order to solve the above-mentioned problem, the invention described in claim 1 includes a master rope for hanging a lifeline for preventing falls, a fixing portion for fixing one end of the master rope provided on the ceiling wall of the building, and a master rope. A movable attachment portion for fixing the end and a drive means for moving the movable attachment portion in the horizontal direction are provided, and the drive means moves the movable attachment portion in the horizontal direction to move the master rope up and down.

請求項2に記載された発明は、請求項1に記載の発明において、駆動手段は水平方向に往復動するピストンと、ピストンを駆動するシリンダとを備え、ピストンには可動取付部が固定されており、ピストンを水平方向に移動させて親綱の上下位置を調整していることを特徴とする。   According to a second aspect of the present invention, in the first aspect of the present invention, the driving means includes a piston that reciprocates in the horizontal direction and a cylinder that drives the piston, and a movable mounting portion is fixed to the piston. The vertical position of the parent rope is adjusted by moving the piston in the horizontal direction.

請求項3に記載された発明は、請求項1又2に記載の親綱装置は複数設けてあり、一方の親綱装置の固定部と可動取付部との間に他方の親綱装置の固定部又は可動取付部の何れか一方を設けており、一方の親綱装置の親綱と他方の親綱装置の親綱とは連続して垂れ下がっていることを特徴とする。   The invention described in claim 3 is provided with a plurality of master rope devices according to claim 1 or 2, and fixing the other master rope device between the fixed portion and the movable mounting portion of one master rope device. Or the movable attachment portion is provided, and the master rope of one master rope device and the master rope of the other master rope device are continuously suspended.

請求項4に記載された発明は、請求項1〜3の何れか一項に記載の発明において、建物の柱には操作部が設けられており、操作部の操作により命綱の使用時に親綱を命綱の懸架位置まで下げると共に命綱の非使用時に親綱を天井壁の近傍位置まで上げることを特徴とする。   The invention described in claim 4 is the invention according to any one of claims 1 to 3, wherein an operation part is provided on the pillar of the building, and the master line is used when the lifeline is used by operating the operation part. Is lowered to the position where the lifeline is suspended, and when the lifeline is not used, the parent line is raised to a position near the ceiling wall.

請求項1に記載の発明によれば、トラックの荷台上で作業する場合は、駆動手段により可動取付部を水平方向の一方向に移動させて、親綱を下方に移動させる。一方、トラックの荷台上で作業をしない場合は、駆動手段により可動取付部を水平方向の他方向に移動させて、親綱を上方に移動させる。   According to the first aspect of the present invention, when working on the truck bed, the movable attaching portion is moved in one horizontal direction by the driving means, and the master rope is moved downward. On the other hand, when the work is not performed on the truck bed, the movable attaching portion is moved in the other direction in the horizontal direction by the driving means, and the master rope is moved upward.

このように、建物の天井壁に設けた可動取付部を水平方向に移動させて親綱を上下動させることができるので、作業時には親綱を下方に移動させて命綱を親綱に掛けることができ、作業終了後は親綱を上方に移動させることができ、親綱が他のトラック通過の際に邪魔にならない。   In this way, since the movable attachment provided on the ceiling wall of the building can be moved horizontally to move the master rope up and down, it is possible to hang the lifeline on the master rope by moving the master rope downward during work. It is possible to move the master rope upward after the work is completed, so that the master rope does not get in the way when passing another truck.

また、親綱を上下動させることができるので、作業者の位置に合わせて親綱の高さ調整ができる。   Moreover, since the master rope can be moved up and down, the height of the master rope can be adjusted according to the position of the operator.

従来技術に示すような親綱を掛け渡す支柱をトラックに併設する必要がないため、トラックの荷台上で作業を行なう毎に支柱を設置したり、作業終了後に支柱を片付けたりする必要がなく作業性に優れ、別途設置スペースが必要にならない。   Since there is no need to install a support straddling the master rope as shown in the prior art on the truck, there is no need to install a support post every time the work is performed on the truck bed or to clear the support post after the work is completed. It has excellent performance and does not require a separate installation space.

請求項2に記載の発明によれば、請求項1に記載された発明と同様の効果を得られるとともに、水平方向のピストン駆動により親綱の上下位置を調整しているので、巻取りにより親綱を上下動させる場合に比べて上下動の応答性が良い。   According to the second aspect of the invention, the same effect as that of the first aspect of the invention can be obtained, and the vertical position of the main rope is adjusted by driving the piston in the horizontal direction. Responsiveness of vertical movement is better than when moving the rope up and down.

請求項3に記載された発明によれば、請求項1又は2に記載された発明と同様の効果が得られるとともに、一方の親綱装置の親綱と他方の親綱装置の親綱とは連続して垂れ下がっているので、命綱を掛けている作業者の作業範囲を広げることができ、荷台での作業がし易い。   According to the invention described in claim 3, the same effect as that of the invention described in claim 1 or 2 can be obtained, and the master rope of one master rope device and the master rope of the other master rope device are Since it hangs down continuously, the work range of the worker who is hanging the lifeline can be expanded, and the work on the loading platform is easy.

また、一方の親綱と他方の親綱とを別々に操作することで、トラックの荷台の高さが前後で異なる場合においても、荷台の高さに応じて親綱を荷台の高さまで近付けることができ、荷台の前後で連続した作業がし易い。   In addition, by operating one master rope and the other master rope separately, even if the height of the truck bed differs from front to back, the master rope should be brought close to the height of the bed depending on the height of the bed. It is easy to work continuously before and after the loading platform.

請求項4に記載された発明によれば、請求項1〜3の何れか一項に記載された発明と同様の効果が得られるとともに、作業終了後には操作部を操作して親綱を天井壁の近傍位置まで上げることができるので、命綱の非使用時に例えばウイングトラックがウイングを開いたままで作業場内を移動する際にも親綱がトラックの走行の邪魔にならない。   According to the invention described in claim 4, the same effect as that of the invention described in any one of claims 1 to 3 can be obtained. Since it can be raised to a position near the wall, when the lifeline is not used, for example, when the wing truck moves in the work place with the wing opened, the master rope does not interfere with the running of the truck.

以下、図面を参照しながら本発明の一実施形態について説明する。図1は本発明の実施の形態に係る親綱装置を概略的に示す図であり、命綱の使用時を示す側面図、図2は図1に示す親綱装置において、命綱の非使用時を示す側面図、図3は図1に示す親綱装置の平面図である。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram schematically showing a master rope device according to an embodiment of the present invention, and is a side view showing when the lifeline is used, and FIG. 2 is a diagram showing when the lifeline is not used in the master rope device shown in FIG. FIG. 3 is a plan view of the master rope device shown in FIG.

図1に示すように、本発明の実施の形態に係る親綱装置1、2は、屋根付き作業場に2つ設けられており、各親綱装置1、2は転落防止用の命綱3を掛ける親綱5と、建物の天井壁7に設けた親綱5の一端を固定する固定部9と親綱5の他端を固定する可動取付部11と、可動取付部11を水平方向に移動させる駆動手段13とを備え、駆動手段13が可動取付部部11を水平方向に移動させて親綱5を上下動させるようになっている。   As shown in FIG. 1, two master rope devices 1 and 2 according to the embodiment of the present invention are provided in a work place with a roof, and each master rope device 1 and 2 hangs a lifeline 3 for preventing falls. The master rope 5, the fixed part 9 that fixes one end of the master rope 5 provided on the ceiling wall 7 of the building, the movable attachment part 11 that fixes the other end of the master rope 5, and the movable attachment part 11 are moved in the horizontal direction. Drive means 13, and the drive means 13 moves the movable mounting portion 11 in the horizontal direction to move the master rope 5 up and down.

駆動手段13は水平方向に往復動するピストン15と、ピストン15を駆動するシリンダ17とを備え、ピストン15及びシリンダ17はフレーム19を介して天井壁7に取り付けられている。ピストン15の先端にはリング状の可動取付部11が固定されており、フレーム19に設けられたスライド軸21上を可動取付部11が移動することで、親綱5の他端が水平方向に移動するようになっている。尚、本実施の形態ではピストン15が突出すると、固定部9と可動取付部11との間の距離が広がり、親綱5が上方に移動するようになっている。一方、ピストン15が収納されると、固定部9と可動取付部11との間の距離が狭まり、親綱5が下方に移動するようになっている。   The driving means 13 includes a piston 15 that reciprocates in the horizontal direction and a cylinder 17 that drives the piston 15, and the piston 15 and the cylinder 17 are attached to the ceiling wall 7 via a frame 19. A ring-shaped movable mounting portion 11 is fixed to the tip of the piston 15, and the other end of the master rope 5 is moved in the horizontal direction by moving the movable mounting portion 11 on the slide shaft 21 provided on the frame 19. It is supposed to move. In the present embodiment, when the piston 15 protrudes, the distance between the fixed portion 9 and the movable mounting portion 11 increases, and the master rope 5 moves upward. On the other hand, when the piston 15 is housed, the distance between the fixed portion 9 and the movable attachment portion 11 is narrowed, and the master rope 5 is moved downward.

尚、一方の親綱装置1の固定部9と可動取付部11との間に他方の親綱装置2の可動取付部11を設けており、一方の親綱装置1の親綱5と他方の親綱装置2の親綱5とは連続して垂れ下がっている。   In addition, the movable attachment part 11 of the other parent rope apparatus 2 is provided between the fixed part 9 and the movable attachment part 11 of one parent rope apparatus 1, and the parent rope 5 of the one parent rope apparatus 1 and the other The master rope device 2 hangs continuously from the master rope 5.

尚、作業場内の柱にはコントロールボックス(操作部)23が設けられており、コントロールボックス23を操作して、ピストン15を水平方向に移動させて親綱5を上下動させるようになっている。尚、コントロールボックス23では、2つの親綱装置1、2を同時に操作することもできるし、それぞれ別々に操作することもできる。   In addition, the control box (operation part) 23 is provided in the pillar in the workplace, and the master box 5 is moved up and down by operating the control box 23 and moving the piston 15 in the horizontal direction. . In the control box 23, the two master rope devices 1 and 2 can be operated at the same time, or can be operated separately.

次に上述の構成を基に本実施の形態に係る親綱装置の作用について説明する。トラック50の荷台51上でシート掛けやシート外しの作業を行なう場合は、コントロールボックス23を操作し、可動取付部11を水平方向の一方向に移動させて、親綱5を下方に移動させる。一方、作業をしない場合には、コントロールボックス23を操作して、可動取付部11を水平方向の他方向に移動させて親綱5を上方に移動させる。   Next, the operation of the master rope device according to the present embodiment will be described based on the above-described configuration. When performing the work of hooking and removing the seat on the loading platform 51 of the truck 50, the control box 23 is operated to move the movable mounting portion 11 in one horizontal direction and move the master rope 5 downward. On the other hand, when the work is not performed, the control box 23 is operated to move the movable attachment portion 11 in the other direction in the horizontal direction and move the master rope 5 upward.

このように、建物の天井壁7に設けた可動取付部11を水平方向に移動させて親綱5を上下動させることができるので、作業時には親綱5を下方に移動して命綱3を親綱5に掛けるとともに、作業終了後には親綱5を上方に移動させることができ、親綱5が他のトラック50の通過の際に邪魔にならない。特に、親綱5を天井壁7の近傍位置まで上げることで、命綱3の非使用時に例えばウイングトラックがウイングを開いたままで屋根付き作業場内を通過する際に親綱5が邪魔にならない。   As described above, the movable attachment portion 11 provided on the ceiling wall 7 of the building can be moved in the horizontal direction to move the master rope 5 up and down. The master rope 5 is hung on the rope 5 and the master rope 5 can be moved upward after the work is completed, so that the master rope 5 does not get in the way when the other truck 50 passes. In particular, by raising the master rope 5 to a position near the ceiling wall 7, the master rope 5 does not get in the way when the lifeline 3 is not used, for example, when the wing truck passes through the covered work place with the wing open.

また、柱に設けたコントロールボックス23の操作により親綱5を上下動させることができるので、作業者の位置に合わせて親綱5の高さ調整ができる。   Further, since the master rope 5 can be moved up and down by operating the control box 23 provided on the pillar, the height of the master rope 5 can be adjusted in accordance with the position of the operator.

また、従来技術に示すような親綱5を掛け渡す支柱をトラック50に併設する必要がないため、トラック50の荷台51上で作業を行なう毎に支柱を設置したり、作業終了後に支柱を片付けたりする必要がなく作業性に優れるとともに、別途設置スペースが必要にならない。   In addition, since it is not necessary to install a support straddling the master rope 5 as shown in the prior art on the truck 50, a support is installed every time work is performed on the loading platform 51 of the truck 50, or the support is cleared after the work is completed. This makes it easy to work and eliminates the need for additional installation space.

一方の親綱装置1の親綱5と他方の親綱装置2の親綱5とは連続して垂れ下がっているので、命綱3を掛けている作業者の作業範囲を広げることができ、作業がし易い。   Since the master rope 5 of one master rope device 1 and the master rope 5 of the other master rope device 2 hang down continuously, the work range of the worker who is hanging the lifeline 3 can be expanded, Easy to do.

尚、本発明は上述した実施の形態に限定されず、その要旨を逸脱しない範囲で種々の変形が可能である。   The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.

図4は変形例に係る親綱装置を示す側面図である。図4に示すように荷台51の高さが前後で異なるトラック50での作業を示している。この場合、一方の親綱装置1と他方の親綱装置2を別々に操作することで、親綱5を荷台51の高さまで近付けることができ、トラック50の荷台51の高さが前後で異なる場合においても、荷台51の高さに応じて親綱5を荷台51の高さまで近付けることができ、荷台51の前後で連続した作業がし易い。   FIG. 4 is a side view showing a master rope device according to a modification. As shown in FIG. 4, the work on the truck 50 in which the height of the loading platform 51 is different between the front and rear is shown. In this case, by operating one master rope device 1 and the other master rope device 2 separately, the master rope 5 can be brought close to the height of the loading platform 51, and the height of the loading platform 51 of the truck 50 is different between the front and rear. Even in this case, the master rope 5 can be brought close to the height of the loading platform 51 according to the height of the loading platform 51, and it is easy to perform continuous work before and after the loading platform 51.
