Anti-deflection angle structure of a multi-hanging-point crawler crane,

Abstract

The invention discloses an anti-deflection angle structure of a multi-hanging-point crawler crane. The structure comprises a fixing seat and a hanging box, fixing holes are formed in four corners above the fixing seat, a tension sensor is arranged below the fixing seat, and the hanging box is arranged below the tension sensor. The anti-deflection angle structure has the beneficial effects that thetension sensor detects the magnitude of the tension borne by each hoisting rope in real time, so that the hoisting process of a corresponding hoisting winding drum can be conveniently controlled, thetension of each hoisting rope is maintained in a balanced range, the deviation angle process is prevented, meanwhile, the speed of a stepping motor can be controlled to be matched with the speed of ahoisting motor so as to control a winding drum support and the hoisting winding drum to move back and forth, the hoisting position of the hoisting rope on the hoisting drum is always above a guide pipe, so that orderly winding of the hoisting rope on the hoisting drum can be controlled, and derailment is prevented.

Description

technical field [0001] The invention relates to the technical field of crawler cranes, in particular to an anti-deflection structure of a crawler crane with multiple lifting points. Background technique [0002] Crawler cranes are cranes that are equipped with traveling devices, lifting devices, luffing devices, and slewing devices on the crawler chassis. Crawler cranes have an independent energy source, compact structure, relatively small dimensions, and good mobility. To meet the fluidity requirements of construction cranes, crawler cranes can be divided into three types according to different transmission modes: mechanical, hydraulic and electric, and multi-lifting point crawler cranes are used more. [0003] However, most of the existing multi-lifting point crawler cranes are not equipped with an anti-deflection structure when performing lifting operations. During the lifting process, deflection often occurs, resulting in a very unstable lifting process and potential saf...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the deficiencies of the existing technology, a multi-suspension-point crawler crane anti-deflection structure is proposed, which solves the problem that most of the existing multi-suspension-point crawler cranes do not have an anti-deflection structure when performing lifting operations. During the process, the deflection angle often occurs, resulting in the process of lifting heavy objects is very unstable, there are potential safety hazards, and during the lifting process, when the hoisting drum is rewinding the sling, the sling will run along the hoisting drum Spiral winding, sometimes stay in a certain position for a long time and fall off
