Problems solved by technology

[0004] The existing cable synchronous control mainly obtains the screw speed through the encoder, which must be combined with the travel limit switch for synchronous control, which is complicated to control and high in cost
The lack of large travel speed and displacement compound measurement device and method restricts the improvement of the performance and cost of the cable synchronous control system

Abstract

The invention discloses a compound testing device and testing method for the moving speed and displacement of marine winch cables. The testing device includes a support, a coil spring, a rope storage drum, a supporting shaft, a testing gear and a two-way Hall switch; the supporting shaft Installed on the bracket, the rope storage cylinder is installed on the support shaft through the bearing, one end of the coil spring is fixedly connected with the bracket, and the other end is fixed on the rope storage cylinder; a test gear is fixedly installed on the rope storage cylinder, and the test gear is connected with the rope storage cylinder. The rope storage barrel is coaxial; the bidirectional Hall switch is installed on the bracket corresponding to the test gear, and the axis of the bidirectional Hall switch passes through the center of the gear; the bracket is provided with a wire rope end locking device corresponding to the rope storage barrel. The present invention adopts the reel to test the steel wire rope contact method to measure the moving speed and displacement, and the measuring displacement range is large; the present invention is provided with a vortex coil spring to provide a certain tension and restoring force to ensure the tightness of the test steel wire rope, avoiding disorderly ropes, and the tracking measurement accuracy is relatively high. high.

Description

technical field [0001] The invention relates to the technical field of marine ship-mounted winches, in particular to a composite testing device and testing method for the moving speed and displacement of cables of marine winches. Background technique [0002] Marine winches are mainly used in the retraction and release of deep sea resource development equipment, ROV systems, underwater towing systems, etc., on which the dielectric armored cable not only transmits force, but also transmits power sources and signal sources, with a large diameter. The operation of thousands of meters in the deep sea makes the armored cable on the marine winch involve long-distance multi-layer winding problems. The quality of the cable system directly affects the stress state and life of the armored cable, and the synchronous control of the cable is extremely important. In order to realize the cable discharge control, the speed and position of the cable discharge mechanism must be measured. ...
