Device and method for measuring torque and torsion angle of steel wire rope

Abstract

The invention discloses a steel wire rope torque and torsion angle measuring device. The steel wire rope torque and torsion angle measuring device comprises a first main shaft, a multi-axial dynamic torque sensor and a second main shaft which are connected in sequence on the same axis, and a double-direction thrust ball bearing is arranged on the first main shaft. Both sides of the double-direction thrust ball bearing are provided with deep groove ball bearings. A front plate and a bottom plate are respectively arranged on one sides, away from the double-direction thrust ball bearing, of the two deep groove ball bearings. The bottom plate is provided with an anti-rotation bolt, the double-direction thrust ball bearing and the two deep groove ball bearings are externally wrapped with casings, the front plate is provided with a dial plate, and the first main shaft passes through the center positions of the dial plate and the front plate respectively. The invention also discloses a steelwire rope torque and torsion angle measuring method, the steel wire rope torque and torsion angle measuring method uses the steel wire rope torque and torsion angle measuring device to realize the determination of a torque and torsion angle of a steel wire rope, and the steel wire rope torque and torsion angle measuring method is specifically implemented according to the following steps: 1, testing the torque of the steel wire rope, and 2, testing the torsion angle of the steel wire rope.

Description

technical field [0001] The invention belongs to the technical field of steel wire rope detection, relates to a measuring device for the torque and torsion angle of the steel wire rope, and also relates to a method for measuring the torque and torsion angle of the steel wire rope. Background technique [0002] At present, in many important use occasions of steel wire ropes in China, such as crawler cranes and steel wire ropes for high hoisting, it is necessary to use anti-rotation or low-rotation steel wire ropes. The torsion angle of the steel wire rope, due to the strict requirements of the method on the length of the sample and the additional load, coupled with the rotational inertia generated by the self-weight of the steel wire rope during the measurement process, it is difficult to accurately determine the torsion angle of the steel wire rope. [0003] The Chinese patent titled "Measuring Tool for Wire Rope Torque and Rotation" (Patent No. 201120040898.7, Publication No...
