Horizontal guide device for crane

Abstract

The invention relates to the technical field of cranes, in particular to a horizontal guide device for a crane. The horizontal guide device comprises a mounting rack fixedly mounted on an end beam, two rotating sleeves are rotatably mounted on the mounting rack, and a locking structure is mounted between each rotating sleeve and the mounting rack and used for fixing the rotating sleeve on the mounting rack. Each rotating sleeve is internally provided with an eccentric shaft in an inserted mode; each eccentric shaft comprises a mounting part mounted in the corresponding rotating sleeve and an extending part extending out of the rotating sleeve; the mounting parts and the extending parts are not coaxial, and the mounting parts are in drive connection with the rotating sleeves through keys; two ends of each rotating sleeve are provided with locking nuts which are in threaded connection with the eccentric shafts; two horizontal guide wheels are rotatably mounted on the extending parts and are located at the two sides of a rail respectively. The horizontal guide device for the crane provided by the invention can realize adjustment of the horizontal guide wheels in the horizontal and vertical directions, is convenient to adjust and can ensure the operation safety of the whole crane.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a horizontal guide device for cranes. Background technique [0002] For cranes with large spans and high operating speeds, in actual production, due to various reasons, the cranes will run skewed and cause serious wear between the wheels and the rails, which is the so-called rail gnawing phenomenon. Due to severe wear and tear, some crane wheel workpieces have a lifespan of only a few months, and some crane rails have to be replaced in advance. On the other hand, the transmission mechanism needs to overcome greater resistance during skewed operation, and the carrying capacity of the transmission mechanism and the capacity of the motor need to be increased accordingly in the design. Therefore, people seek various methods to try to overcome and improve the above phenomenon. [0003] At present, horizontal guide wheels are often installed on the end beam of the crane. However, after...

Problems solved by technology

[0004] The object of the present invention is to provide a horizontal guide device for cranes, which aims to solve the inconvenience of adjusting the gap between the horizontal guide wheel and the track in the prior art. With the wear of the horizontal guide wheel, it is necessary to replace the worn horizontal guide wheel with a new one The horizontal guide wheel, the technical problem of high cost
