Abstract

The utility model discloses a dismounting device for a blowout preventer cylinder sleeve. The dismounting device comprises a screw, a gland, a cam, a torsion transmitting wheel and a casing, wherein the cam is arranged at a side hole on the casing; the torsion transmitting wheel is arranged in the casing; an arc notch is formed in the outer wall of the torque transmitting wheel; the outside of the cam is positioned outside the casing; the inside of the cam is positioned in the arc notch; the gland is fixedly arranged on the upper end surface of the casing by the screw; and a polygonal hole is formed in the inner wall of the torque transmitting wheel. After the dismounting device extends into the blowout preventer cylinder sleeve, the torque transmitting wheel is rotated and the cam extends outwards and is clamped into a groove of the cylinder sleeve; and when the torque transmitting wheel is rotated, the torque can be transmitted to the blowout preventer cylinder sleeve and further the blowout preventer cylinder sleeve can be dismounted. When the dismounting device disclosed by the utility model is used for dismounting the blowout preventer cylinder sleeve, the dismounting device has the advantages of high work efficiency, convenience and quickness in operation, low labor intensity, no damage to the blowout preventer cylinder sleeve and remarkable economic benefits.

Description

The provision for disengagement of preventer cylinder sleeve

Technical field

The utility model is the maintenance unit that oil field perforation equipment is used, and is the provision for disengagement of a kind of preventer cylinder sleeve.

Background technology

When oil reservoir adopts the cable conveying gun perforation, the preventer of hermetically-sealed cable is installed, this preventer structure more complicated, its cylinder sleeve adopts and is threaded; Clamping device can not be installed, during dismounting punching pin and hammer be put in groove on the cylinder sleeve and slowly knock just and can dismantle connecting thread, cylinder sleeve is disassembled; Owing to need knock cylinder sleeve, cylinder sleeve is damaged easily, and time-consuming, the effort of the cylinder sleeve of dismounting preventer; Inefficiency, labour intensity is big, causes economic loss easily.

Summary of the invention

The purpose of the utility model provides the provision for disengagement of a kind of preventer cylinder sleeve, increases work efficiency, and makes it easy to operate, quick.

The purpose of the utility model is achieved in that and comprises screw, gland, cam, moment of torsion transmission wheel, shell; Mounting torque transmission wheel in the side opening place mounting cam on the shell, shell has lonely v notch v on the moment of torsion transmission wheel outer wall; The cam outside is in outside the shell; Cam inside is in the lonely v notch v, and screw is fixed on gland on the upper surface of shell, and moment of torsion transmission wheel inwall is a polygonal hole.

The beneficial effect of the utility model is: when the utility model is used to dismantle the preventer cylinder sleeve, and high efficiency, easy to operate, quick, labour intensity is low, can not damage the preventer cylinder sleeve, has remarkable economic efficiency.

Fig. 2 is the sectional drawing after cutting open from A-A among Fig. 1.

The specific embodiment

Embodiment below in conjunction with Fig. 1,2 pairs of the utility model describes.

Can know that by figure the embodiment of the utility model comprises screw 1, gland 2, cam 3, moment of torsion transmission wheel 4, shell 5, the side opening place mounting cam 3 on the shell 5; Mounting torque transmission wheel 4 in the shell 5, the moment of torsion transmission is taken turns and is had lonely v notch v 6 on 4 outer walls, and cam 3 outsides are in outside the shell 5; Cam 3 inside are in 6 li of lonely v notch vs; Screw 1 is fixed on gland 2 on the upper surface of shell 5, and it is polygonal hole that 4 inwalls are taken turns in the moment of torsion transmission, is used for the installing sleeve spanner.

After stretching into the utility model in the preventer cylinder sleeve, rotation torque transmission wheel 4, cam 3 is protruding to stick in the groove of cylinder sleeve, and the rotation torque transmission was taken turns 4 o'clock again, can pass torque to the preventer cylinder sleeve, thereby the preventer cylinder sleeve is disassembled.
