| description | The invention discloses a hydraulic elevator control mechanism with a function of inducing entry of a tubular column. The hydraulic elevator control mechanism comprises a trigger pin, a guide pin, a hydraulic reversing valve and a valve block, wherein the trigger pin is horizontally arranged at the lower part of the valve block; a groove is formed in the trigger pin; the guide pin is vertically arranged in the valve block; and the lower end of a guide sheath is propped against the trigger pin. The hydraulic elevator control mechanism effectively solves the problems that the conventional hydraulic elevator has no tubular column entry judgment function, has more control pipelines, or has wellhead explosion-proof safety and wire breakage caused by a proximity switch. The hydraulic elevator control mechanism provided by the invention has a simple and compact structure, has good applicability, and is safer and more convenient.
