The first step in the operation of underground cable ducts is to open the power covers on the cable ducts. However, since it is necessary to prevent the cable channel from being damaged by external force, the electric power cover plate generally adopts a reinforced concrete cast-in-place and steel covered structure, which has a heavy weight and is usually opened by a plurality of people or by a crane. The specific cable engineering experiences stages of being capable of being researched, designed, constructed, checked and accepted, the cable engineering needs to be opened repeatedly, much manpower and material resources are consumed, and the efficiency of cable field operation is seriously influenced. Particularly, the heavy cover plate positioned on the vehicle type road needs to be hoisted by a crane. However, the problems of road occupation handling, traffic jam and the like caused by the problems become road barricades for urban power cable construction, and a crane used on a pedestrian passageway has a great potential safety hazard. The power for opening the electric cover plate by the crane is over-sufficient, the cost is high, and the economy is not high enough.
At present, there is a need to develop a more portable, safer, time-saving, labor-saving and economical power cover plate opening device.
SUMMERY OF THE UTILITY MODEL
