Device and method for testing torque resistance of coal drill pipe

Abstract

The invention discloses a device and method for testing torque resistance of coal drill pipe. The device comprises a coal drill pipe, a console, a power device, an axial force application device, a torque rotating speed testing device and a loading device. The console is in driving connection with the power device; the power device, the axial force application device and one end of the coal drill pipe are sequentially connected, and the console controls the power device to apply torque force to the coal drill pipe through the axial force application device; the other end of the coal drill pipe is connected with the loading device, and the loading device applies torque to the coal drill pipe and enables the coal drill pipe to generate anti-torque along with the power device through the axial force application device; the torque and rotating speed testing device is connected with the coal drill pipe to detect the anti-torque state of the coal drill pipe; and the detected state data of the coal drill pipe is sent to a console for fault analysis. According to the scheme, the axial thrust and the rotating torque of the coal drill pipe are loaded, so that the coal drill pipe can resist torque under the action of the axial thrust, the torque state is detected and subjected to fault analysis in real time, and the reliability of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a coal drill pipe anti-torque testing device and method. Background technique [0002] Coal drill pipes operate in an environment where high-speed rotation is subject to axial thrust and rotational torque, and are prone to deformation and fracture. Axial thrust and rotational torque cause deformation and fracture. To ensure that the coal drill pipe does not deform and break under working conditions, it is necessary to perform torque resistance testing on the coal drill pipe. [0003] At present, the relevant test equipment only conducts anti-torque testing on coal drill pipes at rated speeds, and cannot simulate the dual effects of axial thrust and rotational torque on coal drill pipes. The anti-torque detection without axial thrust in the test is different from the actual working conditions. Too far, can not meet the actual use state of measuring coal drill pipe. [...
