Description

A special maintenance tool for tension resistance

Technical Field The utility model belongs to the technical field of electric power facilities, and relates to a special maintenance tool for tension resistance.

BACKGROUND OF THE INVENTION With the continuous development of the county economy, the inspection and maintenance of insulators on the line is also increasing. When the line insulator is overhauled, it is necessary to climb up and down the vertical ladder. When working, you need to use tools to hang the ladder. The hanging ladder of the prior art is to add a hook on the top of the original vertical ladder. Although this structure is simple, it swings back and forth when not climbing, which consumes a lot of physical strength, low work efficiency and high risk.

SUMMARY OF THE INVENTION The purpose of this utility model is to solve the technical problems of the prior art that require a lot of energy, low work efficiency, and high risk, and provide a special maintenance tool for tension resistance to overcome the deficiencies of the prior art.

In order to achieve the above purpose, the utility model provides a special maintenance tool for tension resistance, which includes a hook, a vertical ladder and a horizontal ladder provided with handrails; The other end of the horizontal ladder is provided with a pin shaft for fixing the connecting piece; the hook is connected with the connecting piece through bolts; the upper end of the vertical ladder is provided with an elastic belt.

The vertical ladder can rotate around the connecting shaft.

As a further improvement, an anti-slip rubber sleeve is provided on the armrest.

When in use, put the crane together with the worker and the maintenance tool of the utility model in the hanging basket and hoist it on the cross arm of the wire, hang the horizontal ladder on the insulator of the cross arm, lean on the vertical ladder on the pole or the lifting arm and use the elastic The belt is fixed, and workers can carry out maintenance operations. When workers climb, the vertical ladder will not swing, and the anti-slip rubber sleeves on the handrails can effectively prevent workers from slipping. The utility model has the advantages of simple structure and convenient use, and solves the technical problems of high energy consumption, low work efficiency and high risk in the prior art.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawing is a schematic structural view of the utility model.

In the figure 1, handrail 2, vertical ladder 3, connecting shaft 4, anti-slip rubber sleeve 5, hook 6, pin shaft 7, bolt 8, connecting piece 9, horizontal ladder 10, elastic belt

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the accompanying drawings , the utility model is a special maintenance tool for tension resistance, which includes a hook 5, a vertical ladder 2 provided with a handrail 1, and a horizontal ladder 9; The other end of the horizontal ladder 9 is provided with a pin 6 for fixing the connecting piece 8; the hook 5 is connected with the connecting piece 8 through a bolt 7; the upper end of the vertical ladder 2 is provided with an elastic band 10.

The vertical ladder 2 can rotate around the connecting shaft 3 .

The handrail 1 is provided with a non-slip rubber sleeve 4 .

When in use, the utility model is hung on the cross arm of the wire, and the workers can climb to carry out maintenance operations. When the workers climb, the vertical ladder will not swing, and the anti-slip rubber sleeve provided on the handrail can effectively prevent Workers slipped. After use, fold the vertical ladder 90° and put it on the maintenance vehicle without taking up much space. The utility model is safe in use, high in efficiency and convenient to carry, and effectively solves the technical problems existing in the prior art.
