| description | The invention relates to the technical field of coal mining supporting equipment, in particular to a long-service-life three-telescopic stand column for a hydraulic support and the hydraulic support comprising the long-service-life three-telescopic stand column. The liquid inlet pipe structural member comprises a liquid inlet pipe main body, a pipe joint seat and a valve connecting plate. The pipe joint seat comprises a connecting part and a clamping part. The clamping part can be inserted into a clamping groove formed in the cylinder bottom of the outer cylinder, and the clamping part and the clamping groove are clamped in a matched mode. The liquid inlet pipe structural part is fixedly connected with the cylinder bottom by matching and clamping the clamping part and the cylinder bottom clamping groove, and hydraulic oil is ensured to enter the cylinder bottom through the liquid inlet pipe main body and the pipe joint seat and then enter the inner cavity of the outer cylinder so as to ensure the normal work |
