[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a pole work table system temporarily used on a utility pole.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a workbench on a pole has a main body composed of a tread plate 1 made of an aluminum alloy and a pillar 2 made of iron, a telephone pole mounting part 3, and a safety work. It consisted of three parts of the stand part 4. The column 2 extends obliquely downward from the tread 1 and is attached to a utility pole 5 together with a utility pole attachment 3 provided at one end of the tread 1. Thereby, the pole work table is fixed to the utility pole 5.
The other end of the gripper 6 having one end attached to the stand 4 is attached to a cable suspension line 7 or the like. The column working table has such a configuration, and therefore has a disadvantage in that the entire weight is heavy, and in particular, the weight of the main body, which frequently uses iron parts, is large.

[0003] A conventional work using a pole work and a safety device has been performed in a work form as shown in FIG. That is, the worker climbs the pole in a state where the main rope 9 of the safety belt 8 is wrapped around the utility pole 5 in order to prevent the worker from falling when climbing the pole. Next, after fixing the auxiliary rope 10 to the cable suspension wire 7 or the like, the utility pole mounting part 3 is connected to the utility pole 5.
And set the workbench body. After that, the stand 4 is set up and fixed with screws.

[0004] On the assembled workbench, an operator once removes the rope 9 from the safety belt 8. Then, after turning one end of the rope 9 around a utility pole, the other end is attached to the stand section 4 through a ring at the back of the safety belt 8, and actual work on the pole is performed.

After the work on the pole is completed, the work table is removed in the reverse order to the above-mentioned procedure, the rope 9 is removed again from the safety belt 8, and the state is returned to the looped state, and the auxiliary rope 10 is removed and lowered. Pillar.

Conventionally, in order to carry out such a work process, the operator had to remove the rope from the safety belt and reattach it at a high place.

[0007]

[Problems to be Solved by the Invention] Since such a workbench on a pole is heavy, lifting it to a work place on a pole and fixing it to a telephone pole mounting portion are heavy work, and further, a main body of the workbench on a pole. It was necessary to attach a stand to the camera, which led to a reduction in work efficiency and danger.

Further, since the worker is exposed to the unstable state of only the safety belt main rope, there is a danger of falling.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a pole work table system comprising a light pole work table and a safety device which does not cause danger without lowering work efficiency. With the goal.

[0010]

That is, the present invention is directed to a pole work table system which is temporarily mounted on a utility pole to provide a step board made of a high specific strength aluminum alloy for an operator to work on, and one end of the step board. A power pole mounting portion that is provided to extend from the tread plate, and is mounted to be fixed to the power pole, and a pillar portion made of a high specific strength aluminum alloy extending downward from the tread plate to be fixed to the power pole. A workbench comprising a pillar, a safety device gripping portion for gripping a safety belt to be attached to an operator to work on the tread plate, and a rope having a telescopic mechanism in which the safety device gripping portion is attached to one end, And a cable grip portion attached to the other end of the rope and gripping the cable.

[0011]

[Function] In the pole work platform system of the present invention, in order to reduce the weight, the iron support portion of the pole work table is replaced with a high-strength aluminum alloy, the stand is abolished, and the rope is replaced. Instead of the method of maintaining the posture of the worker, a rope with a telescopic function that holds the cable and the safety belt of the worker is used at both ends. Thereby, a safe work form can be taken while the safety belt main rope is left around.

[0012]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a pole work platform of the pole work platform system according to the present invention. In FIG. 1, the workbench on a pole is composed of a main body composed of a tread plate 11 made of an aluminum alloy and a column 12 made of a high-strength aluminum alloy, and a telephone pole mounting part 13. The support part 12
Is extended obliquely downward from the tread 11 and is attached to the utility pole 5 together with the utility pole mounting portion 13 provided at one end of the tread 11. Thereby, the pole work table is fixed to the utility pole 5.

FIG. 2 shows a safety device of this system. A cable-side grip 15 is attached to one end of a rope 14. The rope 14 has the elastic 1
6, and a safety band side hook portion 17 is attached to the other end of the rope 14. That is, the rope 14
The entire length of the rope 14 is adjusted by moving the telescopic tool 16 provided in the middle of the rope 14 (in the left-right direction in the figure). The safety belt side hook portion 17 is attached to the worker's safety belt 8 as described later.

The cable-side gripper 15 shown in FIG.
As shown in (a) and (b), it is used by being attached to the cable suspension side gripping portion 18 or 19 fixed to the cable suspension line 7. FIG. 3A shows a winding type cable suspension side gripping portion 18 of a winding type using a sling belt.
(B) has shown the cable hanging wire side grip part 19 of a screw fastening type wire clip type.

FIG. 4 is a diagram showing a working mode using the workbench system having such a configuration.

In order to prevent the worker from dropping when ascending the pole, the worker climbs the pole in a state where the main rope 9 of the safety belt 8 is wrapped around the utility pole 5. Next, after fixing the auxiliary rope 10 to the cable suspension wire 7 or the like, the utility pole mounting portion 13 is fixed to the utility pole 5, and then the main body of the workbench is installed. In this case, the worker does not remove the rope 9 on the assembled workbench.

After the installation, the cable hanging line side grip portion 18 is turned on the cable hanging line several times on the work table and tightened. Thereafter, the safety band side hook portion 17 which is a cable grip portion of the safety device is fixed to the sling belt. At the same time, the other end of the rope 14 of the safety device is fixed to the ring of the safety band 8 to perform work on the pillar.

On the other hand, after the work on the pillar is completed, the workbench is removed in a procedure reverse to the procedure described above, the auxiliary rope 10 is removed, and the pillar is lowered.

The use of the above-structured workbench system makes it possible to easily and stably work. Therefore, it is not necessary to attach and remove the stand section and replace the rope, which are conventionally performed, and the safety and workability are greatly improved.

Table 1 shows the results of comparing the weight of articles between the conventional work table and the work table according to the present invention. According to this, it can be seen that the weight of the main body has been significantly improved by the elimination of the stand and the aluminum alloy of the support.

[0022]

[Table 1] In the embodiment described above, FIG.
Although the example using the sling belt type cable hanging wire side grip shown in FIG. 3 has been described, the invention is not limited to this, and the wire clip type cable hanging wire side grip shown in FIG. Needless to say, the same effect can be obtained.

[0023]

As described above, according to the present invention, a light pole work platform system and a light pole work platform system including a safety device that do not cause a reduction in work efficiency and do not pose a danger due to work at a high place. Can be provided.
