Description
Technical field
The utility model is related to the brake dresses in oil-well rig ancillary equipment field, specifically a kind of Pneumatic sleeve centralizer
It puts.
Background technology
Stabbing board be for natural gas oil-well rig well location setting of casing when, it is upper button, the special equipment of the artificial righting casing of shackle,
Two kinds of Pneumatic elevation, hydraulic lifting can be divided to.Wherein, Pneumatic sleeve centralizer uses compressed air to be lifted for power, by people
It send to away from the appropriate height of drilling machine platform, carries out setting of casing make-up righting operation.The sleeve centralizer is using large torque, the slow-speed of revolution
Air motor drives hoist engine, drives wire rope rope that lift cart is pulled to complete rack lifting action, rack descending operation dress
It puts mounted on lifting platform side, working condition requirement can be met by 1 people's operation of control element.But the Pneumatic sleeve centralizer
When upper and lower rack slides in guide groove, if occur pneumatic device die, stop the supple of gas or steam when failures can not self-actuating brake, there are one
Fixed security risk.
Utility model content
The purpose of this utility model be for above-mentioned technical problem, provide it is a kind of simple in structure, safe and reliable, can pre- gas-tight
Dynamic device such as is died, stops the supple of gas or steam at the brake gear of the Pneumatic sleeve centralizer of failures.
In order to achieve the above objectives, the utility model uses following technical scheme：A kind of brake dress of Pneumatic sleeve centralizer
It puts, including the frame that brakes, which is fixedly arranged in elevator fixed plate, and brake frame roof is equipped with air supply processing equipment, stops
Frame one end vertical direction is equipped with brake fixed plate, and brake steel band connecting plate is equipped in the middle part of the brake fixed plate, and brake is fixed
Air cylinder support is equipped at the top of plate, cylinder is fixedly arranged on air cylinder support；The cylinder piston boom end be external screw thread, cylinder piston rod
It is connected by adjusting swivel nut with pull rod one end, the pull rod other end is equipped with swivel nut, and compression spring one end is in contact through pull rod with swivel nut, presses
The spring other end is connected through brake steel band connecting plate by steel belt lacing with brake steel band, and brake steel band is equipped with brake shoes.
The utility model has the advantages that：
The utility model is braked using the frictional force of brake shoes and elevator, when the pneumatic device of Pneumatic sleeve breaks
Gas is stopped the supple of gas or steam when failures, can be made elevator fast braking, be prevented the generation of security incident.Its is easy to operate, time saving and energy saving, can
Effectively cope with the emergency that the upper and lower rack occurred due to pneumatic device is died falls downwards in guide groove, Ke Yizuo
For auxiliary body's extensive use of Pneumatic sleeve centralizer.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of brake gear of Pneumatic sleeve centralizer, including the frame 10 that brakes, the brake frame 10 is solid
In elevator fixed plate 12,10 top of brake frame is equipped with air supply processing equipment 8, and brake 10 one end vertical direction of frame is equipped with
Brake fixed plate 1,1 middle part of brake fixed plate are equipped with brake steel band connecting plate 13, air cylinder support are equipped at the top of brake fixed plate 1
14, cylinder 7 is fixedly arranged on air cylinder support 14；Cylinder piston boom end is external screw thread, and cylinder piston rod is by adjusting swivel nut 6 with drawing
5 one end of bar connects, and 5 other end of pull rod is equipped with swivel nut 4, and 3 one end of compression spring is in contact through pull rod 5 with swivel nut 4,3 other end of compression spring
It is connected through brake steel band connecting plate 13 by steel belt lacing 2 with brake steel band 11, brake steel band 11 is equipped with brake shoes 15.
When needing righting casing, lift cart slides up and down, this brake gear is in opening state, when stabbing board reaches righting
During operation height, lift cart stops sliding, which is in braking state, is specially：The slip of lift cart be by
Gas in air supply processing equipment 8 enters air motor 9 and elevator 16 is driven to drive, and in lift cart sliding process, makes cylinder 7
Piston rod is released, and because adjustment swivel nut 6, pull rod 5, swivel nut 4, compression spring 3 and steel belt lacing 2 have been assembled into an entirety, works as piston
Linkage structure is integrally formed in this when bar is released, and moves downward steel belt lacing 2, causes the rubbing surface of brake shoes 15 and elevator 16
Depart from, brake is opened；When lift cart stops sliding, the rod chamber air inlet of cylinder 7 makes piston rod retract, in the bullet of compression spring 3
Under the pulling force of power and piston rod, above-mentioned linkage structure moves upwards, and contacts brake shoes 15 and the rubbing surface of elevator 16, at this time for
Braking state；And if run into when dying or stop the supple of gas or steam situation, if the brake gear, this element of pressing spring 3 completes brake work,
Because compression spring 3 is elastic force that compression spring 3 is adjusted by swivel nut 4, when running into above-mentioned emergency, compression spring 3 is because of its own resilient band
It moves above-mentioned linkage structure to move upwards, brake shoes 15 is made to be contacted with the rubbing surface of elevator 16 and keep braking state.
