A cable trench cover opening device

Abstract

The invention discloses a cable trench cover opening device. A hoisting device is installed at the lower part of the top plate. The hoisting device comprises a first hydraulic cylinder, a first suspending plate arranged at the lower part of a piston rod of the first hydraulic cylinder, and two suspending plates arranged on the lower part of the first suspending plate. The chain on the lower part of the side, the lower part of the chain is provided with a grab hook, the grab hook includes a symmetrical and inclined splint, and a W-shaped plate arranged in the middle of the splint on both sides. Separation; when the splints on both sides are parallel, the spacing is smaller than the width of the cable trench perforation. In the initial state, the spacing between the upper parts of the two plywood is greater than the cable trench perforation width. In the invention, two chains are connected at both ends of the lower part of the first hanging plate of the hoisting device, hooks are arranged at the lower part of the chains, the hooks are used to extend into the perforated lower part of the cover plate of the cable trench, and the first hydraulic cylinder is used to lift the cover plate of the cable trench , Complete the opening of the cable trench cover, reduce the labor intensity of workers, and enhance the safety of the cable trench cover opening.

Description

technical field [0001] The invention belongs to the technical field of electric power construction, and particularly relates to a cable trench cover opening device. Background technique [0002] The cable trench cover is mainly used for laying the top of the cable trench inside and outside the power plant and substation. It is used as a cover to protect cables and wires from moisture and damage. Zinc steel, cast iron, cement products, etc., the general cable trench cover is made of cement steel bars, and the weight can reach 120-400kg. [0003] In the traditional construction process, when the construction personnel are constructing, or when the operation and maintenance personnel are performing maintenance work such as checking the hole blocking, the construction personnel use suspending ropes to tie them to the lifting holes of the cable trench cover, and then hoist and move. However, for these overweight cable covers, it is more laborious to lift and move, the labor int...

AI Technical Summary

Problems solved by technology

However, for these overweight cable covers, lifting and moving are laborious, and the labor intensity of construction workers is relatively high, and it is impossible to ensure the stability of the cable trench covers during lifting and moving; another lifting method is to use prying Sticks are manually lifted, this method is also more labor-intensive, and it is easy to cause damage to people during the lifting process
