Driller operation seat lifting and rotating device

Abstract

The invention discloses a driller operation seat lifting and rotating device. The driller operation seat lifting and rotating device is characterized in that a turntable bearing outer ring is fixedly arranged on the upper surface of a bottom plate of the lifting and rotating device, a membrane type clamping cylinder installation barrel is arranged in the middle of the upper surface of the bottom plate, and a plurality of membrane type clamping cylinders are arranged between the membrane type clamping cylinder installation barrel and a turntable bearing inner ring. A bearing cover plate is fixedly arranged on the upper end face of the turntable bearing inner ring, an inner guide sleeve is fixedly connected on the outer edge of the bearing cover plate, and a heightening pipe is fixed on the upper surface of the bearing cover plate in a concentric mode. An air bag lower connection plate is arranged on the upper end face of the heightening pipe, an air bag is arranged on the upper surface of the air bag lower connection plate, and an air bag upper connection plate is arranged on the upper end face of the air bag. An outer guide sleeve is fixedly connected on the outer edge of the air bag upper connection plate in a downward mode, and the outer guide sleeve is sleeved with the inner guide sleeve in a sliding mode. The driller operation seat lifting and rotating device is stable in motion, easy to control and reliable in locking.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a lifting and rotating device for a driller's operating seat. Background technique [0002] The driller's control room of an oil drilling rig is an indispensable part of a modern drilling rig, and the driller's operating seat is the carrier for the transmission of various operation control commands in the driller's daily work. The driller's operating seat often integrates many components for the driller's control and observation, the entire seat is heavy, and many control cables are arranged inside the seat. [0003] Existing seat lift swivels have limited lift weight and cannot route cables from inside the swivel. Contents of the invention [0004] The purpose of the present invention is to provide a lifting and rotating device for the driller's operating seat, which solves the problems of oil leakage in the lifting of the hydraulic cylinder, unreliable lifting and...
