Description
Technical Field
The invention belongs to the technical field of coiled tubing operation in oil fields, and particularly relates to a coiled tubing straightening device.
Background
With the rapid development of coiled tubing drilling technology, coiled tubing maintenance has been increasingly appreciated. The length of the continuous pipe is usually hundreds of meters to thousands of meters, and the continuous pipe can be locally damaged in the using process and cannot meet the using requirement. For such damage, the damaged portion needs to be removed and the cut position is re-welded, and the pipe needs to be straightened before welding.
The straightening of the steel pipe is usually performed by a pressure straightener or a cross roll straightener. Because the length of the continuous pipe is very long, the front end and the rear end of the steel pipe are on the equipment, and the steel pipe cannot rotate in the straightening process. While the conventional pressure straightening machine cannot straighten curves with different conditions without rotating the steel pipe, the cross roll straightening machine needs to rotate the steel pipe in the straightening process, so that the straightening of the continuous pipe cannot be satisfied by the two machines. Accordingly, one skilled in the art provides a coiled tubing straightener that solves the problems set forth in the background above.

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention provides a continuous tube straightening device, which comprises a fixed support 5, wherein a hydraulic motor 7 is arranged in the middle of the left side of the fixed support 5, a rotary support 3 is arranged on the upper portion of the inner side of the fixed support 5, a rotary support slideway 2 is arranged on the rotary support 3, a chain wheel chain 6 is arranged on the outer side of the rotary support slideway 2, a tube bender 1 is arranged on the inner side of the rotary support 3, a fixed roll shaft 8 is arranged on the upper portion of the tube bender 1, a fixed roll 9 is arranged on the fixed roll shaft 8, a hydraulic cylinder 4 is arranged on the lower side of the fixed roll 9, a pipe bending head 10 is arranged at the upper end of the hydraulic cylinder 4, and the hydraulic cylinder 4 is connected with a hydraulic.
A plurality of supporting wheels are arranged between the rotary support 3 and the fixed support 5, and the rotary support 3 is rotatably connected with the fixed support 5 through the supporting wheels.
The supporting wheels are eight in number and are arranged in bilateral symmetry, and the supporting wheels on the same side are provided with four supporting wheels.
The fixed support 5 is composed of four fixed rods, the lower ends of the four fixed rods are connected with a supporting plate, and a plurality of supports are arranged at the lower end of the supporting plate.
The working principle is as follows:
when the pipe bender works, the hydraulic motor 7 is powered by a hydraulic system (the hydraulic system is not shown in the figure) to drive the chain wheel and chain 6 to rotate, so that the chain wheel and chain 6 enables the rotary bracket 3 to rotate, and the rotary bracket 3 rotates along the supporting wheel through the rotary bracket slideway 2, so that the pipe bender 1 is driven to rotate;
the hydraulic pump 12 provides power, the hydraulic cylinder 4 is driven by the hose 11 to drive the pipe bending head 10 to press the steel pipe to a fulcrum, namely the position of the fixed roller 9, the correction amount of the pipe bending machine 1 is controlled by controlling the stroke of the hydraulic cylinder 4, the fixed roller 9 of the pipe bending machine 1 can be detached, and the continuous pipe can be put in and taken out by detaching.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
