Abstract
The utility model provides an anti-slip safety elevator pin for oilfield well-repairing operation, which is composed of an elevator body, an elevator pin, an upper pin hole and a lower pin hole of the elevator pin, an elevator pin handle movable vertical slot, an elevator pin movable transverse slot, etc. The anti-slip safety elevator pin is provided with a favorable anti-slip function, and the elevator pin springs and automatically resets after being impacted, and can not falling to the ground. The utility model improves the labor condition of well-repairing operation, and is favorable to safety production.
Description
The utility model relates to oil well repairing operation and removes oil pipe security protection problem, particularly the anti-run safety elevator pin of workover operation construction personnel use.
The present elevator pin that uses, be a kind of straight-bar and a porose pin, of atresia be inserted on the upper and lower pin-and-hole on elevator both sides, prevent suspension ring in the suspension ring hole when removing the oil pipe operation since collision deviate from, cause single-ring mechanical accident to occur, or human casualty accident.Being that a rope is fastened on suspension ring again on the pinhole, prevent that the elevator pin from deviating to land.Above-mentioned elevator pin in use if run into collision, then easily deviate from, and can not automatically reset, and is prone to suspension ring and deviates to cause danger by the elevator pin.
The purpose of this utility model can automatically reset after being to develop a kind of upspringing, and also not be used in to fasten rope on the elevator pin and again can not take off the elevator pin that lands, and a kind of anti-run safety elevator pin of satisfaction is provided for the workover treatment personnel.
Above-mentioned purpose is realized by following technical proposals:
This anti-run safety is transferred bayonet lock, and pin-and-hole, the movable upright groove of elevator pin handle, the movable translot of elevator pin handle, elevator pin envelope body and end socket are formed up and down by elevator body, elevator pin, elevator pin.The elevator pin is contained in the upper and lower pin-and-hole, and elevator pin handle can be moving in the movable upright upper and lower activity of groove of elevator pin handle, also can be in the movable translot of elevator pin left-right rotation.
Above-mentioned anti-run safety takes off the elevator pin, be by gravity fall under the elevator pin in the pin-and-hole, prevent that the suspension ring in the suspension ring hole from deviating from, when the elevator body is subjected to impact the elevator pin is upwards moved, pin runs to the movable translot of elevator pin handle upper edge and is blocked, lean on the pin self gravitation to fall into down in the pin-and-hole once more, thereby reach the purpose of anticreep.
Above-mentioned anti-run safety elevator pin when suspension ring need be taken out from the suspension ring hole, only needs to carry on the elevator pin handle to the movable translot of elevator pin handle position, laterally turns left 90 ° and be placed in the translot in the edge, and suspension ring just can be taken out from the suspension ring hole.
The utility model has solved the elevator pin problem of automatically reseting of upspringing, and also need not take other measure elevator pins can not come off and land, and makes that operating worker is very willing to use, and has both improved condition of labor, has guaranteed safety again, has good economic and social benefits.
Accompanying drawing 1 is the utility model overall structure front schematic view.
Accompanying drawing 2 is the utility model overall structure side schematic views.
Details are as follows to embodiment of the present utility model in conjunction with the accompanying drawings:
1 is the elevator body among Fig. 1, the 2nd, and following pin-and-hole, the 3rd, elevator pin, the 4th, last pin-and-hole, the 5th, elevator pin handle, the 6th, the movable upright groove of elevator pin handle, the 7th, the movable translot of elevator pin handle, the 8th, end socket, the 9th, elevator pin envelope body, the 10th, suspension ring hole.
5 is elevator pin handles among Fig. 2, the 6th, and the movable upright groove of elevator pin handle, the 7th, the movable translot of elevator pin handle, the 8th, end socket, the 9th, elevator pin envelope body.
Its operating principle is: when suspension ring need be put into when going in the suspension ring hole (10), with handgrip elevator pin handle (5), when on the movable upright groove (6) of elevator pin handle, carrying near the movable translot of elevator pin handle (7), elevator pin handle (5) is turned left 90 °, and elevator pin handle is placed on movable translot left side.Opening between the upper and lower elevator pin-and-hole is opened, and suspension ring just can be put into suspension ring hole (10), and elevator pin handle (5) is turned right 90 °, elevator pin (3) falls automatically, seal the opening between the upper and lower elevator pin-and-hole, suspension ring can not be deviate from, at this moment normal rountrip just.When elevator body (1) is clashed into, elevator pin (3) is when upwards play is run into the movable translot (7) of elevator pin handle upper edge, and elevator pin (3) falls to resetting automatically, has prevented that the elevator pin from deviating from.When needs are taken out suspension ring, the sub-handle of last lifting bayonet lock (5) is to the movable translot (7) of elevator pin handle position, upper edge, turn left 90 °, put down elevator pin handle (5) in the left side, the opening of sealing between the upper and lower elevator pin-and-hole is opened, and suspension ring just can be taken out from suspension ring hole (10).The operating principle of both sides elevator pin is identical, and operates simultaneously.
Claims (2)
1, a kind of anti-run safety elevator pin, hole, the movable upright groove of elevator pin handle, the movable translot of elevator pin handle, elevator pin envelope body and end socket are formed up and down by elevator body, elevator pin, elevator pin, it is characterized in that the elevator pin is contained in the upper and lower pin-and-hole, elevator pin handle can also can turn left and right in the movable translot of elevator pin in the movable upright upper and lower activity of groove of elevator pin handle.
2, according to the described anti-run safety elevator of claim 1 pin, it is characterized in that when the elevator body was subjected to impact the elevator pin is upwards moved, pin ran to the movable translot of elevator pin handle upper edge and is blocked, gravity by pin self falls into down in the pin-and-hole, reaches the anticreep purpose.
