Large tonnage lifting hook performance test bench

Abstract

The invention relates to a large tonnage lifting hook performance test bench. A rotation assembly comprises: a pedestal, a turntable, a wire rope connecting seat and a hydraulic clamping assembly. The pedestal is connected with the turntable. The wire rope connecting seat is respectively fixed on the turntable. The wire rope connecting seat is connected with a wire rope through a bolt which passes through a center of the wire rope connecting seat. Two hydraulic cylinders are fixed on the turntable. A loading assembly comprises: an installation platform, a jack seat, a jack, an I beam, supporting seats. The jack seat is fixed on the bottom installation platform. The jack is installed in the jack seat. A top of the jack is fixedly connected with the supporting seats through the I beam. The two supporting seats are connected with each other through a supporting shaft. The test bench possesses a double test function of loading and rotation flexibility and a function of overall combinationtest. The test bench can be used to satisfy a detection requirement of lifting hook loading performance which includes: lifting hook pulley tension, lifting hook head tension, lifting hook and pulleyconnection board tension and the like. Simultaneously, the test bench is suitable for detecting rotation flexibility of the lifting hook head.

Description

technical field [0001] The invention relates to a hook performance test bench, in particular to a large-tonnage hook loading and rotation performance test bench. Background technique [0002] There may be some failure problems during the use of the large tonnage hook group. These failures will have a relatively large impact on the performance of the hook, and will also cause safety hazards to the safety performance of the hook operation. For example, during use, the opening of the hook becomes larger, the wear of the dangerous section, the poor bearing fit, the plastic deformation and torsion of the hook, and the broken hook caused by the essential problems of the hook, etc. Although there have been many preventive measures for human factors, according to the literature search, the development of the test bench for performance testing of hooks has basically not been reported in China. Some small-tonnage hooks can be simply tested on some large-scale tensile test benches or ...
