Description

Technical Field

[0001] The utility model relates to the technical field of anti-sway structures of track-type beam lifting machines, in particular to an anti-sway structure of track-type beam lifting machines. Background Art

[0002] The beam lifting machine is a gantry crane specially designed for bridge construction. The beam lifting machine is mainly composed of assembled main beams, outriggers, overhead cranes, etc. The components are connected by pins and high-strength bolts, which are easy to disassemble and transport. Compared with ordinary gantry cranes, it is easy to install, fast, economical and practical.

[0003] At present, the anti-sway structure of the track-type beam lifting machine in the prior art usually drives the gear to rotate by rotating the driving motor, and then drives the movement of the two adjusting racks, and drives the movement of the adjusting seat, thereby facilitating the equidistant adjustment of the span of the beam lifting machine. During use, since the existing beam lifting machine cannot adjust the overall height, when beam lifting machines with different lifting heights are required at different construction sites, it is necessary to purchase new beam lifting machines with different lifting heights. This not only increases the cost, but also wastes the construction progress. There is a problem that the height of the beam lifting machine cannot be adjusted. In addition, during use, since the overhead crane and the hoist are connected by a wire rope, the stability is insufficient. During the lifting of the beam, the beam is prone to shaking, which affects the position accuracy of the beam lifting. At the same time, there are safety hazards and the problem of swinging is prone to occur during the lifting process. Utility Model Content
