Embodiment Construction

[0009] In order to solve the asynchronous phenomenon when the crane has multiple lifting points, it is first necessary to use a mechanical method or an electronic control method to make the multi-layer winding drum 1 with multiple lifting points rotate at the same speed. 3 Connect the reel adjustment flange 2 with bolts on the inner side, the length of the reel 1 becomes shorter, the shape of the reel adjustment flange 2 can be semicircular or other geometric shapes, the connection of the reel adjustment flange 2 Bolt connection can be used, and other connection methods can also be used. The thickness of the reel adjustment flange 2 just balances the asynchrony of the two suspension points. The reel adjustment flange 2 can be made of metal materials or other materials. Because the rotating speed of the reel 1 is the same, and the number of winding circles is equal, the reel flange 3 on the inner side of the lifting point with a slow lifting speed is bolted to the reel adjustmen...

Abstract

An apparatus for equalizing between asynchronous lifting points of lifter is composed of steel cable, spool for winding said steel cable by multiple layers, spool flanges, equalizing beam, and a spool regulating flange at the internal side of spool flange for changing the active length of spool to equalize between asynchronous lifting points.

Description

Technical field: [0001] The invention relates to a device for balancing the asynchronous lifting points of a crane, which is especially suitable for balancing the asynchronous lifting points when a crane with a multi-layer winding reel uses multiple lifting points to jointly lift the same heavy object. Background technique: [0002] When the hoisting mechanism of a crane often uses multiple lifting points to lift the same heavy object, due to the diameter of each wire rope, the elastic modulus of each wire rope, the force of each wire rope, the wear of each wire rope, the diameter of each drum, and the size of each drum The wear and tear of the diameter will not be absolutely the same, so that the lifting speed of the connection point between the wire rope and the heavy object will not be exactly the same, resulting in asynchrony of multiple lifting points, which generally increases with the increase of the lifting height. The out-of-synchronization of multiple lifting point...
