Embodiment Construction

[0028] as attached figure 1 , figure 2 As shown, the first embodiment of the high-precision torque measuring device for oil pipe fitting disassembly rack includes a support plate 1 , a clamping body 3 , a tension pressure sensor 8 and a data acquisition and display system 10 .

[0029] The supporting plate 1 is a supporting part in the whole device, which plays a supporting and fixing role.

[0030] The clamping body 3 is an important part for clamping the workpiece and transmitting torque. The clamping body 3 is freely rotatably mounted on the support plate 1 through bearings. The clamping body 3 is provided with a clamping mechanism for clamping the workpiece. The clamping mechanism is composed of a plurality of hydraulic cylinders 11 arranged uniformly around the axis of the clamping body 3 and fixed on the clamping body 3 . A force-measuring rod 4 is provided along the radial direction of the rotation track of the clamping body 3 , and the force-measuring rod 4 is fix...

Abstract

The invention relates to a high-precision torque measurement device and method for a petroleum pipeline dismounting frame. The device comprises a supporting plate, a clamping body, a force measuring rod, a pull pressure sensor and a data acquisition and display system, wherein the clamping body is rotatably installed on the supporting plate through a bearing; the clamping body is provided with a workpiece clamping mechanism; the force measuring rod is arranged along the radial direction of the rotating track of the clamping body and is fixedly connected with the clamping body; the stressing direction of a force sensor is perpendicular to the force measuring rod; one end of the force sensor is in threaded connection with a sensor seat, the other end of the sensor seat is articulated with the supporting plate through a first pin shaft, the other end of the force sensor is in threaded connection with a sensor ball, and the other end of the sensor ball is articulated with the force measuring rod through a second pin shaft; and the data acquisition and display system is connected with the pull pressure sensor through a wire. By using the high-precision torque measurement device, a torque value can be accurately measured during turn-lock buckling, and can be displayed in a digital form, the torque can be accurately measured and controlled, and the reliability of products in threaded connection can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of petroleum machinery, and relates to a device and a method for measuring threaded connection torque used in a dismounting rack of petroleum pipes. Background technique [0002] In the petroleum industry, workpieces such as casing, tubing, drill pipe, downhole tools, jars, shock absorbers, and screw drilling tools need to be threaded, and most of these products are used in the downhole environment, and their reliability is particularly high. Important, among which the reliability of threaded connections is the main factor affecting these products. At present, controlling the reliability of threaded connection is mainly realized by controlling the torque of threaded connection. Therefore, the control problem of screw connection torque is very important in the screw connection of the above-mentioned products. [0003] In recent years, different forms of threaded turnbuckle equipment have emerged as the time...
