Description

Lifting device for cable trench cover

technical field

The utility model belongs to the field of lifting devices, in particular to a lifting device for a cable trench cover plate.

Background technique

At present, before working in the cable trench or when repairing and replacing the cable trench cover itself, it is necessary to move the cover a short distance. There is no special device for the movement of the cable trench cover, and it is usually carried manually or with a trolley. Loading and shifting is labor-intensive and time-consuming, and the cover plate is likely to overturn and cause personal injury and crushing accidents. At the same time, the randomness of manual operation may also easily cause damage to the equipment in the cable trench and the cover plate itself.

Utility model content

The purpose of the utility model is to provide a cable trench cover lifting device with simple structure, convenient operation and disassembly, and reduced labor force.

The technical solution to realize the purpose of this utility model is:

A lifting device for a cable trench cover, comprising a lever, a lever sleeve, a bearing, a load-bearing bracket, a universal wheel, a grab hook and a chain; the lever is movably connected to the bearing through the lever sleeve, and the bottom end of the bearing is fixed on the load-bearing bracket; Each end corner of the bottom end of the load-bearing bracket is provided with a universal wheel; one end of the lever is fixedly connected with N chains, N≥2, and the other end of each chain is provided with a grab hook.

Compared with the prior art, the utility model has significant advantages:

The cable trench cover lifting device of the utility model utilizes the principle of leverage to hook the cable cover, and uses the flexible steering function of the universal wheel to place the lifting cover aside; and the position of the lever sleeve can be flexibly adjusted, which is convenient for the staff to operate flexibly , reduce the labor intensity of the staff, and the structure is simple, easy to operate and disassemble.

Below in conjunction with accompanying drawing, the utility model is described in further detail.
