The negative pressure sucker is a sponge sealing sucker. The negative pressure between the negative pressure sucker and the power cable trench cover plate is increased through the negative pressure pump, and the power cable trench cover plate is adsorbed by utilizing the difference of internal and external air pressure.

In this embodiment, in order to realize the lifting action of the negative pressure adsorption mechanism, the hydraulic cylinder 33 is vertically installed on the upper portion of the movable frame, the lower end of the telescopic rod of the hydraulic cylinder is connected with the lifting frame, the guide rods 34 connected with the lifting frame are respectively arranged on the front side and the rear side of the hydraulic cylinder, and the upward guide shafts 35 of the lifting frame are vertically installed on the two sides of the movable frame, which are respectively positioned on the hydraulic cylinder, so that the upward auxiliary guide of the lifting frame is realized through the upward limiting rods.

In this embodiment, in order to ensure the safety problem in the negative pressure adsorption process, clamping and locking are performed when the lifting height after the adsorption in place is reached. The clamping mechanism comprises a fixing frame 41 arranged on the lower side of the movable frame, and the negative pressure adsorption mechanism is located in the fixing frame to perform lifting action and does not interfere with the clamping mechanism.
