Abstract
The utility model provides a non-conventional type tubing elevator. The middle of a main body of the elevator is provided with a flying ring groove; an upper arm is arranged on top of the flying ring groove; a lower arm is arranged at the bottom of the flying ring groove. The upper arm is longer than the lower arm. The flying ring groove is arranged slantways upwards. When operators hang flying rings, as long as the flying rings are pushed inside the outer side of the upper arm and outside the outer side of the lower arm of the main body of the elevator, the flying rings can slide into holes along an oblique upward cant of the flying ring groove; and the accident of a single flying ring will not occur; operators will be safe; oil tubes will not be destroyed; by adopting the utility model, significant economic benefit and social benefit will be created.
Description
One, technical field
The utility model belongs to oil field oil, well power tool, particularly a kind ofly removes the special-shaped pipe elevator that oil pipe is used.
Two, background technology
In the oil-water well operation process, will be with thousands of rice bran oil pipes from the ground G.I.H, or in well, it is tripped out, and oil pipe generally is by 9 meters single oil pipes how long to be formed by connecting, thousands of rice bran oil pipes are coupled together by hundreds of oil pipes, thousands of rice bran oil pipes to be lowered to one by one or trip out during operation, need be stuck under the box cupling on every oil pipe top with pipe elevator it is sling, realize removing the work of oil pipe.Upper arm, underarm on the present pipe elevator main body are equally long, and suspension ring groove level is offered.When hanging suspension ring, simultaneously to rising, two suspension ring are laid by two operators under working rig promotes for two suspension ring, and capacity does not enter in the suspension ring groove simultaneously, suspension ring occur and enter the suspension ring groove, another suspension ring also do not enter the suspension ring groove just to the problem that rises, and have only suspension ring stressed this moment, and the scene is called single-ring, because it is stressed asymmetric, cause personal injury accidents easily, also damage oil pipe easily, cause heavy economic losses.
Three, summary of the invention
The purpose of this utility model provides a kind of special-shaped pipe elevator, makes it safe in utilization, and human casualty accident does not take place, and does not damage oil pipe.
The purpose of this utility model is achieved in that the middle part of elevator body has the suspension ring groove, and the top of suspension ring groove is upper arm, and the bottom of suspension ring groove is a underarm, and upper arm is longer than underarm.The suspension ring groove is opened obliquely.
The beneficial effects of the utility model are: the problem of single-ring can not take place, and operator's safety zero defects can not damaged oil pipe, has remarkable economic efficiency and social benefit.
Four, description of drawings
Accompanying drawing is the front view of the utility model embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
The middle part of elevator body 1 has suspension ring groove 2, and the top of suspension ring groove 2 is upper arm 4, and the bottom of suspension ring groove 2 is a underarm 3, and upper arm 4 is longer than underarm 3.Suspension ring groove 2 is opened obliquely.When the operator hung suspension ring, as long as suspension ring are shifted onto within the elevator body 1 upper arm outside, outside the underarm outside, suspension ring just can slide in the hand-hole along on suspension ring groove 2 inclined-plane obliquely.Other parts on the main body 2 are same as the prior art.
