A shaking inner wall protection device for electric construction tools

Abstract

The invention discloses an electric construction tool shaking inner wall protecting device. The device comprises a chain, a thickened wear resisting shell, a hook, a stop shell, an anti-scratch chainclamping device and a handle; the top end of the chain is mounted in the stop shell for movable connection; the anti-scratch chain clamping device comprises a hand rocking shaft, bearing shells, a block to be pressed, a wear resisting pressure block, a limiting slide assisting rod and an extrusion rebound device; two bearing shells are provided and symmetrically distributed at the upper and lowerends of the hand rocking shaft; when equipment is used, the pulled chain can be joined on the wear resisting pressure block to apply force to a main mandrel, and a return plate is extruded; and in order to assist convenient return when the resistance is lost, rods on two sides move down along with control grooves, auxiliary balls cannot stop movement of the chain, closing balls are inwards extruded along with absorbing airbags to expand two sides, and support rods are expanded to stress on elastic plates to limit the sliding position without generating shaking collision damage to the inner wall.

Description

technical field [0001] The invention belongs to the field of electric power, and more specifically relates to a swaying inner wall protection device for electric construction tools. Background technique [0002] Among the auxiliary tools for electric power construction, there is a kind of power construction tool shaking inner wall protection device is a hand lever hoist. It is mainly used to pull heavy objects, whether it is vertical or horizontal, as long as there is a point that it can fix, it can move the weight. Objects are pulled in the desired direction, and the objects connected by the pull are chains. [0003] Based on the above inventors' discovery, the existing electric power construction auxiliary devices mainly have the following deficiencies, such as: [0004] When the required object is pulled horizontally on the high cable, it will shake due to external factors, wind, etc., because it is manual, not only the pulling force is increased, but also the chain pull...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technology, when the required object is pulled horizontally on the high cable, it will shake due to external factors, wind, etc., because it is manual, not only the strength of pulling is increased, but also the chain pulls The shaking inertia of the heavy object is also relatively large, and it will hit the inner wall of the main body, which will easily deform over time and even affect the service life
