Abstract
The invention discloses an anti-releasing elevator for oil drilling. The anti-releasing elevator comprises an elevator main body and a lifting lug, wherein a lug hole and a notch are arranged on the lifting lug, the lug hole is used for placing a hanging ring, and an anti-releasing device is installed in the notch. The anti-releasing device comprises a stop dog and a rotating shaft, wherein the stop dog sequentially performs resetting, locking and closed circulating motion around the rotating shaft. Due to the fact that the stop dog is further provided with the locking action compared with the prior art, during locking of the stop dog, the lug hole of the lifting lug cannot be shielded, and users can easily and fast pick and place the hanging ring, so that the anti-releasing elevator is time-saving and energy-saving. When the stop dog is in the resetting or closing state, a blocking portion of the stop dog is arranged on the lug hole of the stop dog, so that the working position of the hanging ring is effectively limited, the hanging ring can only move in the lug hole of the lifting lug and cannot get out from the lug hole of the lifting lug, and major safety accidents caused by falling of the hanging ring can be avoided.
Description
Technical field
The invention belongs to the oil drilling apparatus field, relate in particular to a kind of oil drilling anticreep elevator.
Background technology
In the oil drilling construction operation, elevator is to remove the drill string necessary tool, connects suspension ring on it, carries drill string down.In use, suspension ring are very easily scurried out in the elevator earhole, and serious accident takes place, and come off from the elevator earhole for preventing suspension ring, and elevator all arranges disconnecting prevention structure, come off and cause security incident from the elevator earhole in order to avoid suspension ring.What common anti-drop device adopted is latch, at elevator hanger place pin hole longitudinally is set exactly, plug a latch then at the latch place, effect by latch just can stop suspension ring to come off from the elevator hanger, this anti-drop device is simple in structure, be easy to processing, but there are a lot of shortcomings in this bolt-type anti-drop device:
A, because latch is unfixing in pin hole, so latch might drop out from pin hole, if pounding the people can cause security incident, if latch is fallen in the well and will be caused great economic loss.
When b, operative employee do not insert latch, occur suspension ring easily and do not hang up properly just lifting of elevator, the phenomenon of single-ring lifting occurs, consequence is extremely serious.
C, curved as if in use as if suspension ring latch being bumped can cause latch to be difficult to take out even can not get, and influences the wellbore construction progress.
D, latch and elevator body are not an integral body, carrying, are causing easily when depositing latch to lose, thereby losing anti-drop function.
Notice of authorization number is CN201606018U, notice of authorization day is the suspension ring anti-dropping device that the Chinese utility model patent on October 13rd, 2010 discloses a kind of elevator, it mainly is made up of block, bearing pin, torsion spring, lock-screw, block is fixed on the elevator body by bearing pin, torsion spring set is connected on the bearing pin, lock-screw is used for fixed pin shaft, prevents that bearing pin from rotating.Block is subjected to the elastic force of torsion spring, is in closed condition always, when hanger hung suspension ring into by needs, with suspension ring near block, block is subjected to thrust, moves in hanger, and suspension ring just are placed in the hanger, block is after losing the thrust of suspension ring, because the elastic force effect of torsion spring, block resets, and suspension ring are kept off in the hanger, when needing to take out suspension ring, pull block top and just can take out suspension ring.This utility model can prevent effectively that suspension ring from coming off from the hanger earhole, and has overcome the defective of bolt-type anti-drop device.But also there is following shortcoming simultaneously in this utility model:
1, the block of this utility model can only be in closed condition, when putting into and take out suspension ring, all need to thrust of block, that could realize block puts into and takes out action, the workman is the push and block piece on the other hand, takes out or put into suspension ring on the other hand, because the gravity of suspension ring and the elastic force effect of torsion spring, the workman takes out the suspension ring effort, and the danger of workman's ten minutes when doing such work, be easy to be injured finger by suspension ring, also wasted the time simultaneously.
2, this utility model anti-drop device be installed on the elevator hanger by bearing pin, by lock-screw bearing pin is fixed on the elevator hanger, prevent that bearing pin from rotating, cause that anti-drop block can't reset, there are a lot of defectives in this fixed form: lock-screw is subjected to the torsion of torsion spring for a long time, fracture easily, often change lock-screw, improved use cost; The long-term use, lock-screw easily gets rusty, and loses it and renders a service, and the part that fractures in elevator is not easy to take out, and needs in the boring of elevator hanger lock-screw to be screwed in the hole again, just can prevent from rotating the moving axis rotation.
Summary of the invention
For the suspension ring anti-dropping device that overcomes above-mentioned elevator put into and take out suspension ring time-consuming, require great effort, injure finger and the lock-screw defective that fractures easily and be difficult to take out, the invention provides a kind of oil drilling anticreep elevator, this anticreep elevator can effectively be limited in suspension ring in the earhole of hanger, can not come off, avoid single-ring to lift by crane the generation of caused serious accident, during use, it is light, time saving and energy saving, safe to pick and place suspension ring, and need not change lock-screw, reduce use cost.
