Abstract
The invention relates to a tightening device, in particular to a pipe casing coupling tightening device. The coupling tightening device comprises a base, an air cylinder is arranged inside the base, a main wrench and a back-up wrench are arranged on the base, the main wrench is connectedly provided with a control device and a motor, a tension sensor and a torque meter which are connected mutually are arranged on the back-up wrench, the back-up wrench is connected with the air cylinder, and the torque meter is connected with the main wrench through the control device. The coupling tightening device uses the torque meter for measuring torque of actions of the main wrench and controls the actions of the main wrench according to the size of the torque, so that precision is high. The coupling tightening device is simple in structure and highly practical.
Description
Technical field
The present invention relates to a kind of device for screwing up, particularly a kind of device for screwing up of pipe box box cupling.
Background technology
Along with technological transformation and the enlarging of newly-built and original factory of large gauging, sleeve pipe factory, the tubing and casing localization process has had very great development.In oil, sleeve pipe manufacturing process, shackle equipment is the key equipment that is only second to machine for threading on the box cupling, and the quality of shackle directly has influence on switching performance and the sealing performance of oil, sleeve pipe on the box cupling.Present standard has all provided strict torque demand to buckleing on the oil of different size, different grade of steels, the sleeve pipe, will squeeze bad oil, casing threads if torque wrench moment is excessive, thread gluing occurs, impact be threaded intensity and sealing; Torque wrench moment is not enough, then can cause releasing, dropout, the phenomenon such as poorly sealed.Oil, sleeve pipe are in long-term military service process, and operating mode is very abominable.In case go wrong, will bring huge economic loss to the oil field user, therefore, shackle equipment is the research direction in the industry always on the advanced reliably box cupling.
Summary of the invention
Of the present invention a kind of for the reliable box cupling device for screwing up of precision.
A kind of box cupling device for screwing up of the present invention comprises base, base inside is provided with cylinder, base is provided with main pincers and back-up tong, described main pincers are connected with respectively control device and motor, interconnective pressure sensor and the torquemeter of having drawn on the described back-up tong, and back-up tong links to each other with cylinder, and described torquemeter links to each other with main pincers by control device.
A kind of box cupling device for screwing up of the present invention utilizes torquemeter to measure the moment of torsion of master's pincers action, and according to the main action that clamps of size control of moment of torsion, precision is high, and the present invention is simple in structure, and is practical.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
Among the figure: the 1-base; 2-master's pincers; The 3-back-up tong; The 4-motor.
The specific embodiment
Embodiment 1.
A kind of box cupling device for screwing up of the present invention, comprise base 1, base 1 inside is provided with cylinder, base 1 is provided with main pincers 2 and back-up tong 3, described main pincers 2 are connected with respectively control device and motor 4, interconnectively on the described back-up tong 3 drawn pressure sensor and torquemeter, and back-up tong 3 links to each other with cylinder, described torquemeter links to each other with main pincers 2 by control device.
A kind of joint hoop screwing machine with effects of the present invention, box cupling is fixedly mounted on the main pincers 2, utilize back-up tong 3 to clamp body, starter motor 4 drives main pincers 2 rotations, the moment of torsion that main pincers 2 rotations produce is passed to torquemeter by the pulling force sensor on the back-up tong 3, by linking to each other the action of the main pincers 2 of control with main pincers 2 control device after the torquemeter analyzing and processing.
