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 oil drilling apparatus field, particularly relate to a kind of oil drilling drop-proof elevator.
Background technology
In oil drilling construction operation, elevator removes the requisite instrument of drill string, and it connects suspension ring, under carry drill string.In use, suspension ring are very easily scurried out in elevator earhole, and serious accident occurs, and for preventing suspension ring from coming off from elevator earhole, elevator all arranges disconnecting prevention structure, causes security incident in order to avoid suspension ring to come off from elevator earhole.What common anti-drop device adopted is latch, exactly longitudinal pin hole is set at elevator hanger place, then a latch is plugged at latch place, suspension ring just can be stoped to come off from elevator hanger by the effect of latch, this anti-drop device structure is simple, be easy to processing, but this bolt-type anti-drop device exists a lot of shortcoming:
A, due to latch unfixing in pin hole, so latch likely can drop out from pin hole, if pound people can cause security incident, if latch is fallen in well will cause great economic loss.
When b, operative employee do not insert latch, easily occur that suspension ring do not hang up properly elevator just lifting, occur the phenomenon that single-ring lifts by crane, consequence is extremely serious.
If if c in use suspension ring latch is touched curved, can cause latch be difficult to take out even can not get, affect wellbore construction progress.
D, latch and elevator body are not one overall, easily cause latch to lose, thus lose anti-drop function carrying, when depositing.
Authorization Notice No. is CN201606018U, authorized announcement date is the lifting ring anti-release device that the Chinese utility model patent on October 13rd, 2010 discloses a kind of elevator, it is primarily of block, bearing pin, torsion spring, lock-screw composition, block is fixed in elevator body by bearing pin, torsion spring set is connected on bearing pin, lock-screw is used for fixed pin shaft, prevents bearing pin from rotating.Block is subject to the elastic force of torsion spring, is in closed condition always, when suspension ring are hung into hanger by needs, with suspension ring near block, block is subject to thrust, moves in hanger, and suspension ring are just placed in hanger, block is after losing the thrust of suspension ring, due to the elastic force effect of torsion spring, block resets, by suspension ring gear in hanger, when needing to take out suspension ring, pull block top and just can take out suspension ring.This utility model can effectively prevent suspension ring from coming off from hanger earhole, and overcomes the defect of bolt-type anti-drop device.But also there is following shortcoming in this utility model simultaneously:
1, the block of this utility model can only be in closed condition, all need to block thrust when putting into and take out suspension ring, putting into and taking out action of block could be realized, the necessary push and block block on the other hand of workman, takes out or puts into suspension ring, due to the gravity of suspension ring and the elastic force effect of torsion spring on the other hand, workman takes out suspension ring effort, and workman's danger very when doing such work, be easy to be injured finger by suspension ring, waste the time simultaneously.
2, this utility model anti-drop device be arranged on elevator hanger by bearing pin, by lock-screw, bearing pin is fixed on elevator hanger, prevent bearing pin from rotating, anti-drop block is caused to reset, there is a lot of defect in this fixed form: lock-screw is subject to the torsion of torsion spring for a long time, easily fracture, often change lock-screw, improve use cost; Long-Time Service, lock-screw easily gets rusty, and loses its effect, and the part fractureed in elevator is not easy to take out, and needs again to hole in lock-screw advances through hole on elevator hanger, just can prevent rotational axis from rotating.
Summary of the invention
