Abstract
The utility model relates to a combined pipe elevator used for lifting and landing oil pipe for oil field oil-water well workover treatment, which comprises an elevator body (1), a body core (2), a deadlock ring(3), a screw (4), a handle(5), a spring(6), a pin axis(7), and a backing pin(8). The body core (2) is arranged in the inner side of the inner circle surface of the elevator body (1) and fixed with the screw (4), the deadlock ring(3) is arranged on the body core (2). Two radial slotted holes symmetrically distributed on the enclosing side of the elevator body(1) are respectively provided with a pin axis(7) on which the spring(6) is arranged, the inner end and the deadlock ring(3) are connected and the outer end is provided with the handle (5). The backing pins (8) are respectively arranged in the upper and lower opposite backing pin on the two lateral ears of the elevator body (1). The pipe elevator utilizes combined structure and can achieve a whole with three norms oil pipe rod by changing the body core and the deadlock ring. The utility model has the advantages of being convenient to use and maintenance, easy to construction transfer, reducing cost and the like.
Description
Technical field:
The utility model relates to a kind of special tool that the oilfield oil well workover treatment removes oil pipe that is used for.
Background technology:
Pipe elevator is the special tool that oilfield oil well workover operation construction process removes oil pipe.The pipe elevator internal diameter that field operation construction is at present used is single, can only be applicable to the oil pipe of single specification, thereby must select corresponding with it elevator respectively for use for the oil pipe of different specification size.Like this, workover treatment team need dispose the pipe elevator of plurality of specifications size, brings instrument innumerable and disordered and resettlement in well site to use troubles such as inconvenience, maintenance amount are big, and cost is increased.
Summary of the invention:
The utility model purpose is to provide a kind of combined type pipe elevator that can be used for different specification size oil pipe rountrip.
The utility model is to realize like this.This kind pipe elevator is made up of elevator body, card body core, block ring, screw, handle, spring, bearing pin and backing pin, and elevator body inner headed face inboard is provided with card body core, and fixes with screw, and card body core is provided with block ring; The elevator body seals in the radially slotted eye of two symmetrical distributions of a side and respectively is provided with a bearing pin, is set with spring on the bearing pin, innerly is connected with block ring, and the outer end is provided with handle; Elevator body both sides ear is respectively equipped with backing pin in the relative up and down backing pin hole.The using method and the course of work of this kind pipe elevator are as follows: when the oil-water well workover treatment removes oil pipe, earlier this elevator is buckled in the tubing coupling bottom, rotating handles makes block ring that the oil pipe body is closed fully then, on carry the hook suspension ring and it is buckled in the ear of elevator both sides plugs backing pin, will join then two oil pipe shackles or connect after can finish the oil pipe rountrip.Because elevator body and card body core, block ring in it are fabricated structures, tubing string for Φ 73mm, Φ 89mm, three kinds of different size types of Φ 114mm (i.e. 2 ", 3 ", 4 " oil pipe); only need to change card body core, the block ring that is complementary with tubing string; can carry out the oil pipe rountrip, and need not to change another pipe elevator.
The utility model adopts fabricated structure, only needs to change function that card body core, block ring can realize three kinds of specification tubing strings of elevator in one, have that uses, maintenance are convenient, the construction resettlement easily, advantages such as saving cost.
Description of drawings:
Fig. 1 is the utility model structural representation.Fig. 2 is its vertical view.
The specific embodiment:
The utility model is provided by following examples.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, the utility model is made up of elevator body 1, card body core 2, block ring 3, screw 4, handle 5, spring 6, bearing pin 7 and backing pin 8, its structure, assembled relation are as follows: elevator body 1 inner headed face inboard is provided with card body core 2, card body core 2 left and right sides fix with screw 4 and elevator body 1 respectively, and card body core 2 is provided with block ring 3; Respectively be provided with a bearing pin 7 in the radially slotted eye of two symmetrical distributions of elevator body 1 sealing one side, be set with spring 6 on the bearing pin 7, the inner is connected with block ring 3, and the outer end is provided with handle 5; Elevator body 1 both sides " ear " are respectively equipped with backing pin 8 in the relative up and down backing pin hole.Wherein, elevator body 1 middle part is the uncovered hollow disc body of a side, and sealing one side is symmetrically arranged with two radially slotted eyes on it, and both sides are symmetrically and are provided with the ear body in uncovered suspension ring hole that the ear outer end is provided with relative up and down backing pin hole.Card body core 2 is a torus, plays the effect of carrying oil pipe load, is the revolution space of block ring 3.Block ring 3 is for carrying the torus that oil pipe is loaded and switching function is arranged together.Handle 5 is used for pulling block ring 3 opens or closes it.Spring 6 is used for guaranteeing that handle 5 is stuck in the elevator card body core slotted eye.Bearing pin 7 is one to be used for connecting the pin rod body of handle 5 and block ring 3.Backing pin 8 is the elevator pin, is the round bar body, is used for inserting the backing pin hole and prevents that suspension ring are hit by a bullet out from the elevator ear.
Claims (1)
1, a kind of combined type pipe elevator, form by elevator body (1), card body core (2), block ring (3), screw (4), handle (5), spring (6), bearing pin (7) and backing pin (8), it is characterized in that: elevator body (1) inner headed face inboard is provided with card body core (2), card body core (2) left and right sides uses screw (4) and elevator body (1) to fix respectively, and card body core (2) is provided with block ring (3); Respectively be provided with a bearing pin (7) in the radially slotted eye of two symmetrical distributions of elevator body (1) sealing one side, be set with spring (6) on the bearing pin (7), the inner is connected with block ring (3), and the outer end is provided with handle (5); Elevator body (1) both sides " ear " are respectively equipped with backing pin (8) in the relative up and down backing pin hole.
