Abstract

The invention relates to a cable trench cover opening technology, in particular to a mechanical lifting appliance for cable trench covers of a substation and a switching station. The invention solves the problem that the conventional cable trench cover opening technology is easy to cause the effects that sealing performance of the cable trench cover becomes poor, time and labor are wasted and the cable trench cover is easy to cause accidental damage to a constructor. The mechanical lifting appliance for the cable trench covers of the substation and the switching station comprises a bracket part and a lifting part; the lifting part comprises a Z-shaped crank, chains, lifting hooks and three-jaw suckers; the upper end of a first chain is wound and fixed at a first horizontal edge of the Z-shaped crank; a first lifting hook is fixedly arranged at the lower end of the first chain; the middle part of a second chain is hung on the first lifting hook; a second lifting hook and a third lifting hook are respectively fixedly arranged at both ends of a second chain; handles of two three-jaw suckers are respectively hung to the second lifting hook and the third lifting hook. The mechanical lifting appliance is suitable for opening the cable trench covers.

Description

technical field [0001] The invention relates to the technology for opening cable trench cover plates, in particular to a mechanical lifting device for cable trench cover plates in substations and switching stations. Background technique [0002] The cable trenches of substations and switching stations are usually sealed with cover plates, which are used to prevent water from entering the cable trenches and to prevent damage to the electrical equipment in the cable trenches. When overhauling the electrical equipment in the cable trench, the cable trench cover needs to be opened. At present, construction workers mainly use tools such as steel shovels and crowbars to pry the cable trench cover, thereby opening the cable trench cover. Practice has shown that this kind of cable trench cover opening technology has the following problems due to its own principle limitations: First, the corners of the cable trench cover will be damaged after a long period of prying, which will caus...
