Description
Technical field
The present invention relates to technical field of electric power more particularly to a kind of self-tightening type pole climbing devices.
Background technique
It is well known that electric power transmission generally uses high hanging wire or underground line mode, underground line is spread due to great in constructing amount, route
If the deficiencies of at high cost, maintenance is inconvenient, factory, school and residence district only in city are used, and most of power transmission line is
Using high hanging wire mode, there are two types of high hanging wires, and one is tower, another kind is rod-type, and rod-type is due to easy for construction, occupied area
It is small, be used widely using the reasons such as safe, the pole climbing device used now use helix circular arc clamping mode；
Climber is, by human body own wt, so that the other side is linked closely on utility poles using leverage, generate larger
Frictional force, to make one to be easy to climb
Based on foregoing description, and equipment in the prior art discovery is combined to belong to since frictional fitting is all passively
Fitting, safety coefficient is inadequate when using for a long time, and electric pole is the cylinder that diameter is gradually reduced from the bottom to top, and user is climbing
The inner diameter size for constantly adjusting climber is needed when bar to adapt to the diameter of electric pole, it is cumbersome, meanwhile, existing device exists
With dare to mention one starve and when be all single-point stress so that the distribution of pressure is not uniform enough, therefore the design is directed to the above problem, if
A structurally reasonable, and functional good self-tightening type pole climbing device is counted out, to improve practicability.
Summary of the invention
The purpose of the present invention is to provide a kind of self-tightening type pole climbing devices, to solve to belong to since frictional fitting is all
Passive fitting, safety coefficient is inadequate when using for a long time, and electric pole is the cylinder that diameter is gradually reduced from the bottom to top, user
The inner diameter size for constantly adjusting climber is needed in pole-climbing to adapt to the diameter of electric pole, meanwhile, existing device with dare
Mention one starve and when be all single-point stress so that the problem that the inadequate uniform operation of distribution of pressure is cumbersome.
The purpose and effect of self-tightening type pole climbing device of the present invention, are reached by technological means in detail below:
A kind of self-tightening type pole climbing device, the self-tightening type pole climbing device include adjusting fastener, first armful of ring, second armful of ring, foot
