In the figure: 1. a first cross member; 2. a second cross member; 3. a pulley mounting hole; 4. a pulley; 5. a wire rope; 6. a hook; 7. a winch; 8. a roller; 9. a guide rail.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1-2, a novel lifting appliance with high balance comprises a first beam 1, a pulley block, a pulley mounting bracket, a winch 7 arranged on the first beam 1, and a plurality of steel wire ropes 5 connecting the winch 7 and the pulley block; the pulley mounting rack comprises a second cross beam 2 and pulley mounting holes 3 arranged on the second cross beam 2; each pulley 4 in the pulley block is arranged in the pulley mounting hole 3, and the lower surface of the pulley mounting frame is provided with a plurality of lifting hooks 6. In the use, after each lifting hook catches on the heavy object respectively, start the hoist engine and promote, promote the in-process, because pulley and lifting hook are restricted on the pulley mounting bracket, can avoid wind-force or rock under the condition, wire rope rocks and leads to the heavy object focus to remove and unbalance, improves the stability of operation. Meanwhile, because the pulley and the lifting hook are limited on the pulley mounting frame, safety accidents caused by random swinging of the lifting hook in a hoisting gap can be avoided.

Further, the winding machine 7 comprises a rack and winding drums respectively corresponding to the pulleys 4 in the pulley block, a rotating shaft and a driving motor for driving the rotating shaft are arranged on the rack corresponding to the winding drums, and the winding drums are installed on the rotating shaft and connected with the pulleys 4 through steel wire ropes 5. Specifically, each reel, axis of rotation and pulley can adopt the one-to-one mode, also can a axis of rotation of a plurality of reels sharing, each the reel install in proper order in the axis of rotation, driving motor drive the axis of rotation rotates, drives each the reel carries out synchronous rotation, and wire rope rolls or unreels for the lifting hook rises or descends.
