technical field

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

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.

Existing seat lift swivels have limited lift weight and cannot route cables from inside the swivel.

Detailed ways

As shown in Fig. 1, the present invention is used to be installed on the driller's operating seat in the driller's control room of an oil rig, and the structure of the lifting and rotating device of the driller's operating seat is that it is included in the base plate 12 of the lifting and rotating device The outer ring 9 of the slewing bearing is fixedly installed on the upper surface (through three bolts), and the diaphragm type clamping cylinder installation tube 10 is installed at the middle position on the upper surface of the bottom plate 12. A plurality of diaphragm clamping cylinders 11 are installed between the 8. After the diaphragm clamping cylinders 11 are inflated, their outer surfaces are closely attached to the inner ring 8 of the turntable bearing, and the lifting and rotating device is lifted under the action of friction. Stop rotation or stay in place for rotation control;

A bearing cover plate 7 is fixedly installed on the upper end surface of the inner ring 8 of the slewing bearing (through three other bolts), an inner guide sleeve 13 is fixedly connected to the outer edge of the bearing cover plate 7, and an enlarged tube is concentrically fixed on the upper surface of the bearing cover plate 7. 6. An airbag lower connecting plate 5 is installed on the upper surface of the added tube 6, an airbag 4 is installed on the upper surface of the airbag lower connecting plate 5 (using hexagon socket screws), and an airbag upper connecting plate 1 is installed on the upper end surface of the airbag 4; The outer edge of the upper connecting plate 1 of the airbag is fixedly connected with the flange 2, and the flange 2 is fixedly connected downward with the outer guide sleeve 3, and the outer guide sleeve 3 and the inner guide sleeve 13 are slidably socketed to realize the overall up and down movement of the seat, as shown in the figure As shown in FIG. 2 , a rotation limiting block 14 is provided on the upper surface of the outer edge of the base plate 12 , and a protrusion in contact with the rotation limiting block 14 is provided on the lower edge of the inner guide sleeve 13 .

Referring to Fig. 3, the electrical control part in the lifting and rotating device of the driller's operating seat is composed of two circuits, one of which is that the air bag 4 communicates with the high-pressure air source through the air control check valve 15, the lifting control switch 16, and the throttle valve 17. The other way is that each diaphragm type clamping cylinder 11 communicates with the high-pressure gas source through the rotary control switch 18 together.

The working principle of the driller's operating seat lifting and rotating device of the present invention is:

1) When the lifting control switch 16 is placed in the "up" position, the air control check valve 15 is opened, and the compressed air flows into the airbag 4, and the airbag 4 expands upwards and drives the entire driller's operating seat and other accessories to move upward through the upper connecting plate 1 of the airbag. . When the lifting control switch 16 is placed in the "stop" position, the air control check valve 15 is closed, the compressed air is enclosed in the air bag 4, and the driller's operating seat and its accessories stop moving up and down. When the lifting control switch 16 is placed in the "down" position, the air control check valve 15 is opened, and the compressed air enclosed in the airbag 4 is slowly discharged under the action of the seat's own weight, and the airbag 4 and the entire seat begin to move downward slowly.

2) When the seat does not need to be rotated, put the rotary control switch 18 in the "locked" position, compressed air enters each diaphragm clamping cylinder 11, and the outer surface of each diaphragm clamping cylinder 11 is tightly attached to it after inflated. On the turntable bearing inner ring 8, the seat is stopped to rotate. When the seat needs to be rotated and the rotary control switch 18 is placed in the "release" position, the compressed air enclosed in the diaphragm clamping cylinder 11 is discharged, and the friction force acting on the inner ring 8 of the turntable bearing disappears, and the seat can be rotated. Free spins.

The characteristics of the lifting and rotating device for the driller's operating seat of the present invention are:

1) The seat is powered by compressed air as a whole, driven by airbags, and can be lifted up and down. It is operated by manual air control valve and has the functions of speed adjustment and up and down movement.

2) Using (six) diaphragm-type clamping cylinders, the seat can be fixed reliably to avoid abnormal rotation of the driller's seat.

3) The seat adopts a thick-walled steel drum as the guide device for up and down movement, and can also play the role of a protective cover. There is a space reserved in the middle of the whole mechanism to ensure the passage of cables and pipelines, and the goal of concealed construction of pipelines and cables; avoid internal structure and The cables are exposed and the appearance is beautiful.
