Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work light stand for equipment, and more particularly to a work light stand that can be easily attached to a frame of equipment such as an elevator and an air conditioner.

[0002]

2. Description of the Related Art FIG. 7 shows a state of equipment operation in a conventional elevator machine room. As shown in FIG. 7, a machine base 1 on which a device 2 such as a hoisting electric motor is mounted is fixed to a floor 5 of the machine room, and on the floor 5 of the machine room, a worker can work. A tool holder 3 in which the take-out tools and parts to be used are stored is placed. An illumination lamp for illuminating the device 2 and the like is provided on the ceiling of the machine room. Further, a handle 30 is provided on the device 2.

No specific device for locking the work light 4 for working illumination is provided in the device 2 or the like when performing the device work. Therefore, for example, the work lamp 4 is hooked on the handle to illuminate the essential parts of the device 2.

[0004]

However, since the handgrip is not a specific device for lighting the work light, even if the work light is hung on this handgear, the inspection / maintenance location of the equipment may not be illuminated. In such a case, the work light must be placed on the feet or held in one hand to perform the work.However, if the work light is held in one hand, the work can be performed only with one hand, and the workability is remarkably increased. It is decreasing.

Further, if the tool case is placed on the floor of the machine room as in the prior art, there is a risk that it may interfere with the feet during the work. In addition, the worker must bend down and pick up the tool and the like each time, which causes a problem of poor workability.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a stand which can be easily attached to an equipment frame and which also serves as a working light for inspection / maintenance work and a tool holder.

[0007]

In order to solve the above problems, the working lamp stand of the device according to the present invention has the following features.

(1) A pillar having a hook for hanging a work lamp near the tip and a fixture for fixing the pillar to a machine base on which equipment is mounted.

As a result, the work light can be hung on the hooks of the columns fixed to the machine base, so that it is not necessary to hold the work light with one hand during maintenance and inspection work. Moreover, since the support column can be arbitrarily fixed to the machine base by the fixing tool, the support column can be attached in the vicinity of a place to be illuminated. Therefore, the workability of maintenance and inspection work is improved.

(2) In the work lamp stand described in (1) above, a tool holder is attached to the support column so that a mounting position on the support column can be changed and the support can be rotated around the support point. An expandable leg is rotatably attached to the bottom surface of the tool holder.

Since the tool holder is attached to the supporting column and the mounting position on the supporting column can be changed, the operator can install the tool holder at an arbitrary height where the tool can be easily taken out during the work. Further, since the bottom of the tool holder is provided with extendable legs, the tool holder is supported by the support column and the foot. Therefore, the tool holder is stably installed at a height suitable for work. Also, since the tool holder is attached rotatably around the fulcrum,
After the work is completed, the tool holder can be folded by rotating it in the direction of the column. Furthermore, since the foot is also rotatably attached to the bottom surface of the tool case, the foot can be folded when the tool case is folded. Therefore, after the work is completed, the work light stand with the tool holder can be compactly folded and carried or put away.

(3) In the work lamp stand described in (2) above, the tool holder and the foot can be turned and folded toward the column.

Therefore, after the work is completed, the tool holder and the foot can be rotated toward the support column to be folded, and the work lamp stand with the tool holder can be compactly folded and carried or put away.

(4) In the work lamp stand according to any one of (1) to (3), the support column includes a fixed support column and an auxiliary support column that is extendably attached to the fixed support column. The hook is attached near the tip of the column.

Since the auxiliary column is attached to the fixed column so as to be expandable and contractible, and the hook is attached near the tip of the auxiliary column, the illumination from the work lamp can be performed from any height. Therefore, any maintenance / inspection work site can be illuminated, and workability is improved.
