ABSTRACT
In the modern mining the hydraulic support is the necessary ancillary equipment, the legs is one of its main elements. The reliability of the legs directly relates the mine pit production normalized and worker's safe.
Along with China coal industry unceasing development, the government to safety dynamics enlarging in production set a higher request to the mineral electromechanical device examination technology.The legs performance test-bed is the legs quality examination of the fittings is the quality monitoring safeguard of the legs.
The legs test-bed of this article designed can compatible European standard and the national standard.,can examine the legs performance of the working resistance reach 8500kN。This article introduced the method of legs performance examination, the test platform composition, designed the loading system and the load bearing frame.
The main content of this article:
1. This article designed the loading system,the hydraulic cylinder,the turbo-charged cylinder, the pumping station fuel tank, joins the cover, the shaft coupling, the load bearing frame in detail.
2. Selected the pumping station of loading, the big pump group, the hydraulic cylinder, the turbo-charged cylinder, the shaft coupling, the cylinder guidance and so on has carried on the cartography.
3. The design of load bearing frame, with the SolidWorks 2007 carries on the design, and drew support to SolidWorks 2007 section finite element analysis tool COSMOS carried on the stress analysis.
