Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerial work vehicle having a work platform at the tip of an extension / bending arm such as a boom / rudder or various aerial work equipment such as a hydraulic / electric / manual work machine. The present invention relates to a tool / equipment box for a work table of an aerial work vehicle / aerial work equipment, which is used by inserting tools and equipment required for work at aerial heights and mounting it on a workbench.

[0002]

2. Description of the Related Art Since it is not possible to come to the ground for tools and equipment when performing work at heights with an aerial work vehicle,
The tools and equipment necessary for a series of work at a high place are put in the tool / equipment box fixed to the work table at the tip of the boom / rudder to work.

[0003]

The above-mentioned conventional tool / equipment box is a structure fixed to the workbench, and therefore, depending on the work position on the workbench, the taken-out tools and equipment can be carried to the work position by hand. The box may become a hindrance, making it difficult to work, which causes a problem of lowering work efficiency and work safety. The present invention provides a workbench tool / equipment box that solves the above-mentioned drawbacks of the prior art.

[0004]

The workbench tool / equipment box of the present invention for solving the above technical problems is "a cross rail of a safety fence surrounding the periphery of a workbench of an aerial work vehicle or aerial work equipment". And a box-shaped tool / equipment storage part, and the hanging hook part is an upper hanging hook part composed of inverted U-shaped hooks that hook on the horizontal rails at two upper and lower positions. It is composed of a lower hook, and a U-shaped hook that hooks on a horizontal rail below is suspended from an elastic spring with a fixed upper end. Has become.

Then, the necessary tools and the like are put in the tool / equipment storage portion, and the upper hook portion and the lower hook portion are hooked from above the two horizontal rails on the safety shelf of the workbench. As well as hooking it, hook the above-mentioned bullet support hook part on the lower horizontal rail to hook it, and use the elastic tightening force of the bullet support hook part to stabilize the posture of attachment to the safety fence and use it. Has become.

[0006]

[Function] The workbench tool / equipment box of the present invention having the above-described structure can be set on the workbench simply by hooking it on the horizontal rail of the safety fence of the aerial work vehicle / aerial work equipment and hooking it. , The safety fence can be set freely at any position, and can be set to the position most suitable for work in high places before or during work, or the position can be adjusted to work efficiently and safely at high places. You can

In addition, since the upper hooks, the lower hooks, and the elastic hooks exist for the hooking, for example, the vertical distance between the horizontal rails of the safety fence is set to the upper and lower hooks. Even if it is not aligned with the spacing of the hooks, the weight of the tools and equipment is supported by the upper hooks, so
If there is a horizontal crosspiece in the inverted U-shaped hook of the lower hook, the tool / equipment box will not rattle or sway, and in addition, the elastic support hook will have a lower horizontal crosspiece. Since it is hooked from below, elastic tension is generated,
The equipment box has good stability in mounting on the workbench, and its tool / equipment storage part is emptied and lightweight, and even if a strong cross wind or wind blows up, it can be detached from the cross rail or lifted up by the wind force. There is no such thing, and sufficient safety can be secured.

[0008]

Embodiments will be described in detail below based on embodiments. With reference to FIG. 1 showing an embodiment of the present invention, in this embodiment, two upper and lower upper horizontal rails 12A and a lower horizontal rail 12B are provided on the upper end of the extension / bending boom 11 of the aerial work vehicle 16. It is used for the workbench 13 around which a safety fence 14 consisting of is formed, and is configured as follows.

That is, sufficient tools necessary for work at high places
A pair of support brackets 3 extending in parallel downward are provided on the back surface of the box-shaped tool / equipment storage unit 2 into which the equipment is put and put in and out through the upper opening. An upper hooking hook portion 5 and a lower hooking hook portion 6 each having a pair of inverted U-shaped hooks 4 protruding outward are provided, and a distance L between the upper and lower hooking hook portions 5 and 6 is equal to that of the safety fence 14. It is set to be approximately equal to the vertical interval between the two horizontal rails 12 on the upper and lower sides. A coil spring 8 having an appropriate spring constant is suspended between the connecting plates 7 that connect the pair of inverted U-shaped hooks 4 of the upper hooking portion 5, and the lower end of the coil spring 8 is also suspended. A U-shaped hook 9 is hung from the upper part, and a spring-supported hook portion 10 including the coil spring 8 and the U-shaped hook 9 is provided. Reference numeral 15 in the figure denotes a reinforcing arm of the support bracket 3.

Then, as shown in FIG. 1B, the upper hook 5 is hooked on the upper horizontal rail 12A of the safety fence 14, and the lower horizontal hook 12 is hooked on the lower horizontal hook 12B. The tool / equipment storage unit 2 containing the tools / equipment is set to the most suitable position for work at a high place on the work table 13, and the U-shaped hook 9 of the suspended hook portion 10 is attached to the lower horizontal rail 12B. It is hung from the lower side, and the elastic tension of the coil spring 8 generates elastic tension between the upper hook 5 and the lower horizontal rail 12B.
Is set tightly against the safety fence 14 without rattling, and the hooks 4 and 9 are hooked and changed, so that the position can be extremely easily used and used.

The above-mentioned embodiment has the above-mentioned effects, and the tool / equipment box 1 can be freely set at the most suitable position for work at high places, and the position during work can be easily adjusted. Further, since the elastic support hook portion 10 elastically fixed to the safety fence 14 exists, the lightened tool / equipment box 1 is not likely to come off or float up in a high place space even when exposed to a strong wind. The distance between the upper and lower horizontal rails 12A and the lower horizontal rail 12B is set so that the upper and lower hooks 5 and 6 are
Even if the distance L does not match, if the lower horizontal rail 12B is provided in the inverted U-shaped hook 4 of the lower hook portion 6, the safety rail 14 can be hooked and set, so various horizontal rail shapes can be obtained. A single tool / equipment box for various aerial work vehicles consisting of
There is a practical advantage that can be shared.

2A and 2B are hexagonal views of the tool / equipment box 1 of the embodiment shown in FIG. 1, where FIG. 2A is a front view thereof, FIG. 2B is a right side view thereof, and FIG. Its plan view,
(D) is its rear view, (E) is its bottom view, and the left side view appears symmetrically with the right side view. The tool / equipment box 1 of the present invention is not limited to the above embodiment, and the tool / equipment storage unit 2 may be changed to another shape / size, or the hooks 4 and 9 may be formed in a wide shape. And so on.

[0013]

As described above, the workbench tool / equipment box of the aerial work vehicle / aerial work apparatus of the present invention has the practicality that it can be commonly used for worktables of various shapes and sizes. Because the mounting set to the workbench can be set and converted at any time to the position most suitable for work at high places, promoting work efficiency and safety of work at high places and simple structure Further, it is provided at low cost and is easily spread, and there is an effect of improving convenience of the worker at a high place.
