Anti-sway jacklift

Abstract

The invention relates to an anti-sway jacklift, comprising a small frame and a lifting driving device. The jacklift is characterized in that a power shaft of the lifting driving device is connected with a transmission shaft and intersects with the axis of the transmission shaft; at least two lifting chain wheels are arranged on the power shaft and the transmission shaft respectively; the small frame is also provided with chain supports; one end of each chain is connected with the chain supports and the other end thereof is connected with the lifting chain wheels; a hanger plate is provided with at least four hanger plate chain wheels; and the hanger plate chain wheels are connected with the chains. The jacklift has the following advantages: the jacklift adopts combination of the chains and the chain wheels to replace the original combination of telescopic columns and the drum-type lifting device, integrates the anti-sway function and the lifting function, can substantially reduce the components with larger volume and the amount of machining in the process of equipment manufacturing and simultaneously can reduce the weight of the equipment self, save the raw materials, reduce the added weight during lifting and save energy.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, in particular to an anti-sway hoisting trolley. Background technique [0002] At present, the anti-shaking of the lifting trolley is completed by a rigid telescopic column installed at the lower end of the trolley frame, and a gripper is installed at the lower end of the telescopic column. The rigid telescopic column of the anti-shake device is welded by steel plates. Although the above-mentioned anti-sway device has the advantage of high rigidity, the rigid telescopic column is heavy, long in length, and difficult to process, requiring large-scale equipment to complete the process. Due to the increase in self-weight, the power of the lifting and running motors increases correspondingly, and the rail beam also increases. Increase accordingly. This will not only increase the construction cost of the factory building, but also increase the power consumption, and there should be no obje...

AI Technical Summary

Problems solved by technology

Although the above-mentioned anti-sway device has the advantage of high rigidity, the rigid telescopic column is heavy, long in length, and difficult to process, requiring large-scale equipment to complete the process. Due to the increase in self-weight, the power of the lifting and running motors increases correspondingly, and the rail beam also increases. increase accordingly

This will not only increase the construction cost of the factory building, but also increase the power consumption, and there should be no objects in the space 3~4 meters below the trolley, and the usable space will be greatly reduced

Moreover, the rigid telescopic column can only play the role of anti-shaking. In addition, a set of reel and wire rope device is needed to complete the lifting of heavy objects, resulting in a complicated structure of the lifting trolley.
