Main end beam connecting structure and bridge crane

Abstract

The invention relates to the technical field of cranes, and particularly discloses a main end beam structure and a bridge crane. The main end beam structure comprises a main beam, a first end beam, a second end beam and a main end beam connecting structure, wherein the first end beam and the second end beam are arranged at the two ends of the main beam, one end of the main beam is fixedly connected to the first end beam, the main end beam connecting structure comprises a positioning column and a pressing plate, the other end of the main beam is fixedly connected to a first connecting plate, the first connecting plate is provided with a through hole, one end of the positioning column is fixedly connected to a second connecting plate of the second end beam, the positioning column penetrates through the through hole and can only slide in the through hole in the length direction of the main beam, a pressing plate is fixedly connected to the other end of the positioning column, the pressing plate limits the positioning column to slide out of the through hole of the first connecting plate, and the pressing plate and the first connecting plate are arranged in a spaced mode. The main end beam connecting structure and the bridge crane solve the problems that errors of the span of the travelling crane are caused by factors such as temperature difference change of a use environment, change of a frame structure, errors existing in track installation, settlement of a plant foundation and the like, and then the travelling crane gnaws a track or gets stuck.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a main end beam connection structure and a bridge crane. Background technique [0002] With the continuous development of the crane industry, there are more and more places to use cranes. Due to the change of temperature difference in the use environment, the long-term operation of the crane, the change of the frame structure, the error of the track installation, and the settlement of the plant foundation, etc., will cause the driving span An error occurs, which in turn causes problems such as driving rail gnawing or driving stuck. Contents of the invention [0003] The purpose of the present invention is to provide a main end beam connection structure and bridge crane to solve the problem of the related technology due to the temperature difference change of the use environment, the long-term operation of the crane, the change of the frame structure, the errors of the track inst...

Problems solved by technology

[0003] The purpose of the present invention is to provide a main end beam connection structure and bridge crane to solve the problem of the related technology due to the temperature difference change of the use environment, the long-term operation of the crane, the change of the frame structure, the errors of the track installation, and the problems of the foundation of the factory building. Subsidence and other factors lead to errors in the span of the train, which in turn causes the problem of rail gnawing or jamming of the train
