Description
Technical field
The invention belongs to the continuous pipe technical field of operation in oil field, and in particular to a kind of continuous pipe straightener.
Background technique
With the rapid development of DRILLING WITH COILED TUBING, a kind of maintenance of continuous pipe is gradually paid attention to.Continuous pipe is logical
Chang Changdu will cause the local damage of continuous pipe, be not able to satisfy requirement in use up to hundreds of meters to thousands of rice.
To this damage, need to remove damaged part, and incision site re-started into welding, before welding, need to pipe into
Row aligning.
The aligning of steel pipe is usually using gag straightener or cross-roll straightening machine.Since continuous length of tube is very long, before steel pipe
Rear end is all in equipment, and steel pipe not can be carried out rotation in straightening process.And common gag straightener can not be revolved in steel pipe
The different bending of situation is aligned in the case where turning, cross-roll straightening machine needs to rotate steel pipe in straightening process, so two
Person is not able to satisfy the aligning of continuous pipe.Therefore, those skilled in the art provide a kind of continuous pipe straightener, above-mentioned to solve
The problem of being proposed in background technique.
Summary of the invention
The purpose of the present invention is to provide a kind of continuous pipe straighteners, and solving existing continuous pipe not can be carried out asking for aligning
Topic.
The technical scheme adopted by the invention is that:
A kind of continuous pipe straightener, including fixed bracket, the fixed bracket left side central portion are provided with hydraulic motor, institute
It states fixed bracket inside upper part and rotary support is installed, rotary support slideway, and rotary support are installed on the rotary support
Sprocket wheel chain is installed on the outside of slideway, bending machine is installed on the inside of the rotary support, the bending machine top is provided with fixation
Roll shaft is provided with fixing roller on the stationary roller shaft, and hydraulic cylinder, the hydraulic cylinder upper end installation are provided on the downside of the fixing roller
There is corner, the hydraulic cylinder connects hydraulic pump by two hoses.
The features of the present invention also characterized in that
Several bogie wheels are provided between the rotary support and fixed bracket, the rotary support is by bogie wheel and admittedly
Fixed rack rotation connection.
The bogie wheel quantity is eight, and is symmetrical set, and there are four bogie wheels for ipsilateral bogie wheel setting.
The fixed bracket is made of four fixed links, and four fixed link lower ends are connected with support plate, the support plate
Lower end is provided with several supports.
The beneficial effects of the present invention are:
The present invention solves the problems, such as that continuous pipe cannot be aligned, and the welding and complete continuous pipe service station for continuous pipe mention
Solution is supplied.

Rotary support slideway 2 is installed, and sprocket wheel chain 6 is installed on the outside of rotary support slideway 2, is installed on the inside of the rotary support 3
There is bending machine 1,1 top of bending machine is provided with stationary roller shaft 8, and fixing roller 9 is provided on the stationary roller shaft 8, described solid
Hydraulic cylinder 4 is provided on the downside of fixed roll 9,4 upper end of hydraulic cylinder is equipped with corner 10, and the hydraulic cylinder 4 passes through two hoses
11 connection hydraulic pumps 12.
Several bogie wheels are provided between the rotary support 3 and fixed bracket 5, the rotary support 3 passes through bogie wheel
It is rotatablely connected with fixed bracket 5.
The bogie wheel quantity is eight, and is symmetrical set, and there are four bogie wheels for ipsilateral bogie wheel setting.
The fixed bracket 5 is made of four fixed links, and four fixed link lower ends are connected with support plate, the support plate
Lower end is provided with several supports.
Working principle:
When the invention works, hydraulic motor 7 provides power (hydraulic system is being not shown in the figure) drive chain by hydraulic system
It takes turns chain 6 to rotate, so that sprocket wheel chain 6 rotates rotary support 3, rotary support 3 is by rotary support slideway 2 along bogie wheel
Rotation, so that bending machine 1 be driven to rotate；
Hydraulic pump 12 provides power, drives corner 10 that steel pipe is pressed to fulcrum by 11 driving hydraulic cylinder 4 of hose, i.e., solid
The position of fixed roll 9, and 1 correct amount of bending machine is controlled by control 4 stroke of hydraulic cylinder, and the fixing roller 9 of bending machine 1 can be torn open
It unloads, by disassembly, being put into and taking out for continuous pipe may be implemented.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
