Description

Technical Field

[0001] The utility model relates to a butt joint device, in particular to a tubing butt joint device. Background Art

[0002] During the pressure operation of oil and water wells, after the tools are lifted out, the tubing must be butted and connected within the high-pressure area. Currently, the method of directly butting the tubing or tubing short joints is used.

[0003] Currently, during the tubing butting process, the tubing is prone to swing, the butt joint is unstable, which affects the subsequent tubing butt joint and poses a potential danger to the subsequent use of the tubing. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tubing butt joint device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tubing butt joint device is provided with two groups of guide rails. On one side of the two groups of guide rails, there are sliders which are slidably connected inside the guide rails. On one side of the slider, there is an outer cylinder which is fixedly connected to the slider. The outer cylinder consists of two semi-circular arc-shaped plates. Inside the outer cylinder, there is an inner cylinder which is slidably connected inside the outer cylinder.

[0007] As a further scheme of the utility model: there is a clamping groove inside the outer cylinder, and the clamping groove is integrally formed on the outer cylinder. There is a clamping block on the inner cylinder corresponding to the clamping groove, and the clamping block is integrally formed on the inner cylinder. The clamping block is slidably connected to the clamping groove.

[0008] As a still further scheme of the utility model: there is an inclined plane inside the inner cylinder, and the inclined plane is integrally formed inside the inner cylinder.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The upper and lower groups of outer cylinders and inner cylinders are in a separated state, and inclined planes are provided on both the outer cylinder and the inner cylinder. The separated outer cylinder and inner cylinder can better insert the tubing into the butt joint device. After the tubing is inserted, the separated outer cylinder and inner cylinder are combined, and the inner surface of the inner cylinder clamps the tubing, and then the tubing butting work is carried out.
