Description

Lifting device for cable trench cover plate used in substation

【Technical field】

The invention relates to a lifting device, in particular to a lifting device for a cable trench cover plate used in a substation.

【Background technique】

As we all know, the substation is a place to change the voltage. In order to transmit the electric energy from the power plant to a distant place, it is necessary to increase the voltage into high-voltage electricity, and then reduce the voltage as needed near the user. The work of the substation must be completed by the substation, so the power supply task undertaken by the substation is a crucial link in the power grid. In order to ensure the stable operation of the equipment and facilities of the whole station, the substation must conduct a firewall inspection every month. The cable trench must be checked and cleaned once, and a large number of cable trench covers must be lifted in each check. Since there is no handle on the cover, it becomes very difficult to lift the cover. When lifting the cover, two people are required to work together. Only crowbars, hand lifts, etc. are used to lift it with brute force. Not only is it easy to cause hand injuries to the operator, but it is also time-consuming for the worker to lift the cable trench cover. It is laborious, which seriously affects the work progress and has potential safety hazards.
