Wire rope winding system for automatically adjusting spreader balance

Abstract

The invention discloses a wire rope winding system for automatically adjusting the balance of a sling. The system includes two drums, four spreader pulley blocks, four upper pulley blocks, four balance levers, four steel wire ropes, four electric push rods and a spreader beam, of which: two drums are wound with four After each steel wire rope is wound out from the drum, the rope is wound on the spreader pulley block and the upper pulley block, and finally the rope is taken up to one end of the balance lever. The other end of the balance lever is connected to an electric push rod. The four spreader pulley blocks are respectively installed on the on the four corners of the beam. Wherein each spreader pulley block is equipped with electrical components such as a wire encoder or a laser range finder to detect the level of the load. This system solves the problem that the load tends to tilt during the process of lifting, transporting and lowering.

Description

technical field [0001] The invention relates to the technical field of bridges and gantry cranes, in particular to a wire rope winding system for automatically adjusting the balance of a spreader. Background technique [0002] At present, the wire rope winding system of the hoisting mechanism in the bridge crane and the gantry crane mainly adopts three structural methods, please refer to the attached figure 1 , attached figure 2 And attached image 3 : [0003] attached figure 1 The wire rope winding system consists of a drum, a spreader block, an upper pulley block, a balance pulley and a wire rope. The wire rope wound out of the drum is wound on the spreader pulley block, upper pulley block and balance pulley, and then wound back to the drum; [0004] attached figure 2 The wire rope winding system includes a drum, a spreader block, an upper pulley block, a balance lever and two wire ropes. The two wire ropes wound out from the reel are respectively wound on the sp...
