Abstract

The invention discloses a fully mechanized coal mining hydraulic support column, relates to the technical field of the fully mechanized coal mining hydraulic support column, and is capable of solving the technical problems that an existing test-bed of a fully mechanized coal mining hydraulic support column is short in loading travel, difficult to adjust the position of the center line of a tested column, is incapable of adjusting the testing length of the test-bed and the like. The test-bed of the fully mechanized coal mining hydraulic support column comprises a first hydraulic oil cylinder, a cross beam, a front beam, a first guide holder, a second guide holder, a movable tail beam and a second hydraulic oil cylinder, wherein the movable tail beam is provided with a driving device, the test-board is further provided with a support trolley and a horizontal guiding device which moves along a ground guide rail, therefore the long-stroke loading of the test-bed of the fully mechanized coal mining hydraulic support column, and the automatic adjustment of the position of the center line of the tested column and the testing length can be comprehensively realized.

Description

technical field [0001] The invention relates to a fully mechanized mining hydraulic support column, in particular to a fully mechanized mining hydraulic support column test bench. Background technique [0002] The fully mechanized mining hydraulic support is one of the key equipment in the fully mechanized coal mining face. It interacts with the surrounding rock to control the roof strata in the working area of ​​the working face, which can support and control the roof of the working face reliably and effectively, and isolate the goaf , prevent gangue from entering the mining face, and provide a safe working space for the working face. [0003] The column is the core power component of the hydraulic support, which effectively connects the top beam and the base of the hydraulic support, and bears the load of the roof. It is the main supporting component of the hydraulic support. According to the requirements of relevant standards, the performance test of hydraulic support co...
