Description
Technical field
The utility model relates to oil drilling, oil recovery or well workover technology field, be particularly related to hydraulic pressure extension tongs and hydraulic oil casing tongs, be the torque sensor of a kind of extension tongs and the special use of oil jacket pipe wrench, specifically a kind of wide range torque sensor with fast mounting mechanism.
Background technology
When oil drilling, workover treatment remove drilling rod, drilling tool, tubing and casing, need use the spinner specific purpose tool that unloads screw thread.The spinner specific purpose tool is hydraulic pressure extension tongs or hydraulic oil casing tongs, the general name hydraulic pipe wrench.The torque wrench moment of drilling rod, drilling tool or oil casing threaded connection directly influences detains quality on the screw thread.Must strict control torque wrench moment during last button.Existing multiple now special spinner moment of torsion detects the controlling recording device, uses on hydraulic pressure extension tongs or hydraulic oil casing tongs.Whether the measurement of the moment of torsion detection controlling recording device on hydraulic pressure extension tongs or the hydraulic oil casing tongs accurately directly affects is buckled quality, therefore, the moment of torsion that needs this special moment of torsion detection caliberating device of hydraulic pipe wrench moment of torsion detection marking apparatus to be used to demarcate on the hydraulic pipe wrench detects controlling recording, and the wide range torque sensor that the hydraulic pipe wrench moment of torsion detects in the marking apparatus is the core of torque measurement.
The wide range torque sensor major defect in usefulness is on the hydraulic pipe wrench at present: the one, transmit the torque arm of torsion and the wide range torque sensor that torque sensor adopts the integral structure of whole processing, and volume is big, heavy, difficult; The 2nd, the torque arm that transmits torsion adopts flange to be connected with the general torque sensor that has the flange termination, very inconvenience of torque sensor dismounting and installation, loaded down with trivial details time-consuming taking a lot of work.
The utility model content
The purpose of this utility model provides a kind of wide range torque sensor of quick fixation structure, torque arm and torque sensor adopt and divide body structure, simple in structure, dismounting and assembling are quick, and the moment of torsion that can realize hydraulic pipe wrench detects, and satisfies the real needs of oil drilling, the strict control of workover treatment torque wrench moment.The volume that overcomes existing sensor existence is big, heavy, difficult; Extremely inconvenience of dismounting and installation, loaded down with trivial details time-consuming deficiency of taking a lot of work.
The technical scheme that the utility model adopted is: the wide range torque sensor of quick fixation structure comprises torque arm, threaded fast-assembling pressure cap, torque sensor main body and torque sensor signal interface.The torque sensor main body adopts tubular torque sensor, in torque sensor main body outer wall center fixed the torque sensor signal interface is arranged, and can connect signal wire on the torque sensor signal interface, and the signal that the torque sensor main body is monitored passes.It is characterized in that: in the center pit of the two ends of torque sensor main body, insert a torque arm respectively.Be fixed with threaded fast-assembling pressure cap on the external thread at torque sensor main body two ends, threaded fast-assembling pressure cap is fixed on torque arm at the two ends of torque sensor main body.
Described torque arm is the cylinder bodily form, and the shoulder of annular protrusion is arranged at the middle part of torque arm; The screw thread of threaded fast-assembling pressure cap one end is an internal thread, and the other end center-hole diameter of threaded fast-assembling pressure cap is less than internal thread diameter, and threaded fast-assembling pressure cap is pressed on the end face of annular protrusion shoulder of torque arm.Threaded fast-assembling pressure cap is pressed together torque arm and torque sensor main body
The utility model compared with prior art has the following advantages: the torque arm and the torque sensor main body that have the profile connection of centering shoulder by employing, make torque arm and torque sensor main body peg graft fast, by threaded fast-assembling pressure cap torque arm and torque sensor main body are pressed together, the center of torque arm and torque sensor main body point-blank, this is by torque arm, down the shoulder on the torque arm is realized.Fast mounting mechanism is compared with flange-type structure and is had advantage simple in structure, quick and easy for installation.
The utility model is simple in structure, easy accessibility, improved work efficiency, greatly reduce labour intensity.Use of the present utility model, the open-air convenient transportation and the dirigibility that help improving the wide range torque sensor.
