Referring to fig. 1, a schematic diagram of hoisting a cable trench cover plate according to the present invention is shown, wherein movable support frames 10 are disposed on two sides of the cable trench cover plate 1, a hoisting mechanism is disposed on each support frame 10, a bearing member 20 is disposed above each hoisting mechanism, a sling chain 21 is disposed on each bearing member 20 for connecting and fixing the cable trench cover plate 1, and the hoisting mechanism is used for driving the bearing member 20 to move up and hoist the cable trench cover plate 1 and then move to the side, so as to easily realize hoisting and moving of the cable trench cover plate 1.
According to the hoisting method of the cable trench cover plate, the used hoisting device is in a modular design, all modules forming the hoisting device can be transported after being disassembled and assembled, and when the hoisting device needs to be used, the modules can be assembled together for use, so that the method is simple and convenient. In a specific using process, a lifting chain 21 is used for binding a lifting hole of the cable trench cover plate 1, then a lifting mechanism arranged on the support frame 10 is used for lifting the bearing part 20 so as to stably lift the cable trench cover plate 1, the lifted cable trench cover plate 1 is stably moved to the side through the roller 11 arranged at the bottom of the support frame 10, after maintenance operation in a cable trench is completed, the support frame 10 is pushed back, and then the cable trench cover plate 1 is put down through the lifting mechanism.
In the invention, in order to make the paths of the cable trench cover plate 1 which is hoisted to move to the side and moves back from the side consistent, the cable trench cover plate 1 is easier to restore; the method provided by the invention also comprises the following steps: roller grooves 40 are pre-laid on two sides of the cable trench cover 1, and the rollers 11 at the bottom of the support frame 10 are placed in the roller grooves 40 to reciprocate along the direction limited by the roller grooves 40. In addition, because the roller 11 rolls in the roller groove 40, the roller 11 is prevented from rolling smoothly due to uneven ground or sludge adhered to the roller 11.
In the hoisting method of the cable trench cover plate provided by the invention, in order to facilitate the disassembly and assembly of the hoisting device, the two ends of the bearing member 20 are respectively provided with the connecting member 30, as shown in fig. 2, the connecting member 30 is provided with a sleeve 31 for sleeving the bearing member 20, and a clamping member 32 with an opening pointing downwards is further arranged below the connecting member 30 for clamping and fixing the power output end of the lifting mechanism.
