Abstract
The utility model provides an anticreep oil pipe elevator belongs to an oil field is instrument for borehole operation, and it has the elevator body, and the handle round pin passes slotted hole and crescent catch on the elevator body and installs together crescent catch towards the side of the elevator body have an arcuation recess, and after the anticreep bolt passed the elevator body, its end was located the arcuation recess on the crescent catch, this kind of oil pipe elevator, because the existence of anticreep bolt, even take place the handle round pin and drop, the anticreep bolt also can play the effect of blockking to the crescent catch, prevents that the crescent catch from droing, has improved the security of production. And the structure is simple, the oil pipe elevator can be transformed on the basis of the existing oil pipe elevator, and the production cost is low.
Description
Technical field
The utility model provides a kind of oilfield downhole operation instrument, especially a kind of pipe elevator.
Background technology
Pipe elevator is the special tool that plays, plays oil pipe or drilling rod in the oilfield downhole operation (as workover treatment).The elevator body is arranged on existing pipe elevator, and slotted eye and crescent lock ring that handle pin passes on the elevator body are installed together.This pipe elevator relies on handle pin to prevent that the crescent lock ring from coming off.Handle pin often takes place to break to take off phenomenon, causes the crescent lock ring to come off, and has an accident but in use.Particularly rising, in the going down process, crescent lock ring case accident very easily occurring, gently then cause oil pipe, drilling rod to fall into the down-hole, heavy then pound and hurt sb.'s feelings or equipment, the safety of production is low.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of anticreep pipe elevator is provided, and comes off effectively to prevent the crescent lock ring, improves the safety of producing.
The utility model is to realize like this, the anticreep pipe elevator, it has the elevator body, slotted eye and crescent lock ring that handle pin passes on the elevator body are installed together, towards the side of elevator body the arcuation groove is arranged at described crescent lock ring, after the anticreep bolt passed the elevator body, its end was positioned at the arcuation groove on the crescent lock ring.
Adopt the anticreep pipe elevator of said structure, because the existence of anticreep bolt, even handle pin comes off, the anticreep bolt also can play the barrier effect to the crescent lock ring, prevents that the crescent lock ring from coming off, and has improved the safety of producing.And simple in structure, can on the basis of existing pipe elevator, transform, cost of production is low.
Description of drawings
Fig. 1 is the front view of the utility model structure.
Fig. 2 is the A-A sectional drawing of Fig. 1.
The specific embodiment
Further specify concrete structure of the present utility model below in conjunction with accompanying drawing.
As shown in drawings, the anticreep pipe elevator of the utility model, it has elevator body (3), the slotted eye (2) that handle pin (1) passes on the elevator body is installed together with crescent lock ring (5), towards the side of elevator body arcuation groove (6) is arranged at described crescent lock ring (5), after anticreep bolt (4) passed elevator body (3), its end was positioned at the arcuation groove (6) on the crescent lock ring (5).
The using method of this anticreep pipe elevator is identical with existing oil card elevator, no longer describes in detail.When the crescent lock ring rotated, anticreep bolt (4) was stuck in the arcuation groove (6) on the crescent lock ring (5), and like this, even handle pin generation case accident, crescent lock ring (5) can not come off from elevator body (3) yet.
This anticreep pipe elevator can be transformed on the basis of existing pipe elevator.During transformation, leave the arcuation groove on crescent lock ring (5), the position corresponding to the arcuation groove gets out screw on the elevator body then, and the anticreep bolt is screwed into screw, and makes its end be positioned at the arcuation groove to get final product.
Claims (1)
1. anticreep pipe elevator, it has elevator body (3), the slotted eye (2) that handle pin (1) passes on the elevator body is installed together with crescent lock ring (5), it is characterized in that, towards the side of elevator body arcuation groove (6) is arranged at described crescent lock ring (5), after anticreep bolt (4) passed elevator body (3), its end was positioned at the arcuation groove (6) on the crescent lock ring (5).
