Driller operating seat of driller room of petroleum drilling machine

Abstract

The invention discloses a driller operating seat of a driller room of a petroleum drilling machine. The driller operating seat comprises a rotating part, a lifting part, a seat and a box body. The rotating part adopts the structure that a bearing outer ring of a turnplate is fixedly mounted on the upper surface of a seat fixing plate; a mounting cylinder is fixedly mounted at the axis position of the seat fixing plate; a plurality of diaphragm type clamping cylinders are mounted on the mounting cylinder circumferentially and uniformly; the outer circumferences of the diaphragm type clamping cylinders are contacted with a bearing inner ring of the turnplate; a rotating limiting plate is arranged on the seat fixing plate; and a convex block corresponding to the rotating limiting plate is arranged on the lower edge of the bearing inner ring of the turnplate. The driller operating seat of the driller room solves the problems that a hydraulic cylinder leaks oil during lifting, an air cylinder is locked unreliably during lifting, the upper box body of the handrail operating box cannot be fixed reliably after being opened, upper and lower box bodies are sealed unreliably, the cable trend is influenced by excessive up-and-down motion guide rods and a rotating locking mechanism is not provided in the conventional products.

Description

technical field [0001] The invention belongs to the technical field of petroleum machinery and equipment, and relates to a driller's operating seat in the driller's room of an oil drilling rig. 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 daily work of the driller, so it is a work seat with reliable performance and high comfort , which is particularly important for drillers. Contents of the invention [0003] The purpose of the present invention is to provide a driller's operating seat in the driller's room of an oil drilling rig, which solves the problem of oil leakage in the lifting of the hydraulic cylinder, unreliable lifting and locking of the cylinder, and opening of the upper box of the armrest operation box in the prior art. The rear cannot be fixed reliably, the seal...

Problems solved by technology

[0003] The purpose of the present invention is to provide a driller's operating seat in the driller's room of an oil drilling rig, which solves the problem of oil leakage in the lifting of the hydraulic cylinder, unreliable lifting and locking of the cylinder, and opening of the upper box of the armrest operation box in the prior art. The rear cannot be fixed reliably, the seal between the upper and lower boxes is not reliable, too much up and down movement of the guide rod affects the direction of the cable, and there is no problem with the rotation locking mechanism
