[0001] The utility model relates to the technical field of automotive auxiliary tools, and particularly relates to a top cover hoist for commercial vehicles. Background Art

[0002] A hoist refers to a device for lifting heavy objects during the process of a hoisting machine. During the production process of commercial vehicles, since a large number of workpieces need to be assembled and welded together, the hoist becomes particularly important, which directly affects the processing volume, production efficiency, manufacturing cost, etc.; however, standard hoists cannot meet all hoisting requirements during the hoisting process, so non-standard hoists are designed to meet the hoisting needs. Using hoists can improve production efficiency, reduce production costs and alleviate labor intensity, etc. Currently, in the processing process of commercial vehicles, generally, workers manually lift the top cover onto the vehicle roof, and multiple people are required to carry one top cover, resulting in high labor costs and being time-consuming and laborious.

[0009] And a hoisting chain, which is fixedly connected to the frame body.

[0010] By adopting the above technical solution, during use, the lifting tool is connected to the lifting equipment through a sling, and the lifting tool is moved to a specified position above the commercial vehicle. The controller controls the vacuum generator to supply air in the forward direction, and the adsorption force is transmitted to the suction cup through an air pipe, and the suction cup adsorbs the top cover; the controller controls the air control valve to supply air, and the air valve drives the clamping member to clamp the edge of the top cover; subsequently, the lifting equipment starts. Under the adsorption of the top cover by the suction cup and the clamping of the top cover by the clamping member, the lifting tool steadily drives the top cover to rise and move above the predetermined position. The controller controls the air control valve to supply air in the reverse direction, the clamping member releases the clamping of the edge of the top cover, the lifting tool drives the top cover to descend to the predetermined position, and the controller controls the vacuum generator to supply air in the reverse direction, and the suction force of the suction cup on the top cover disappears; the lifting equipment moves the lifting tool to the original position, and the lifting operation is completed.
