Abstract

The invention belongs to the technical field of hoisting equipment reliability testing, relates to a tower crane standard joint reliability test stand for simulating actual condition loading, and overcomes the problem that the present reliability test stand cannot perform reliability testing of simulating actual condition loading on the tower crane standard joint. The tower crane standard joint reliability test stand comprises horizontal iron, a baseplate, an X-direction loading part, a Y-direction loading part and an automatic control part. The X-direction loading part comprises a horizontaladjusting unit, a vertical adjusting unit and a load applying unit. The X-direction loading part, and the Y-direction loading part are completely identical in structure. The automatic control part comprises a displayer, an industrial control computer and four sets of servo control units which are completely identical in structure.

Description

technical field [0001] The invention relates to a test device applied to the field of reliability of lifting equipment, more precisely, the invention relates to a reliability test bench for a standard section of a tower crane capable of simulating loading of a standard section of a tower crane under actual working conditions. Background technique [0002] Tower crane is one of the vertical lifting equipment commonly used in engineering construction, which is used to lift various construction materials such as steel bars, concrete, wood boards, and steel pipes. During the working process, the tower crane has to bear its own weight, hanging objects, wind load, and is affected by the ambient temperature, causing frequent failures and serious reliability problems. Relevant media continue to report major accidents during the working process of the tower crane, which has become a The focus of attention of tower crane manufacturers and users. Therefore, it is of great practical si...
