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

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as Figure 1-Figure 3 As shown, the composite testing device for the moving speed and displacement of the marine winch cable of the present invention includes a support 1 , a coil spring 3 , a rope storage drum 2 , a support shaft 5 , a test gear 10 and a bidirectional Hall switch 14 . The support 1 includes a bottom plate 101 and two side plates 102 and 103 vertically installed on the bottom plate; the side plate 102 and the side plate 103 are arranged in parallel. The center of the inner surface of the side plate 102 is provided with a support shaft fixing part, and the side plate 103 is provided with a through hole corresponding to the support shaft fixing part. The diameter of the through hole is greater than the diameter of the support shaft 5, and a sealing end cover is installed at the through hole. 12. The inner side of the sealing end cap 12 is pr...

Abstract

The invention discloses a movement speed and displacement integrated testing device and method of a cable arranging device. The testing device comprises a supporting seat, a coil spring, a rope storing drum, a supporting shaft, a testing gear and a two-way hall switch, wherein the supporting shaft is mounted on a bracket, and the rope storing drum is mounted on the supporting shaft through a bearing; one end of the coil spring is fixedly connected with the bracket, and the other end of the coil spring is fixed to the rope storing drum; the testing gear which is coaxially fixedly mounted on the rope storing drum; the two-way hall switch corresponding to the testing gear is mounted on the bracket, and an axis of the two-way hall switch passes through the center of the gear; a steel wire rope end head locking device corresponding to the rope storing drum is arranged on the bracket. According to the testing device, the movement speed and displacement are measured in a way of pulling a coiling drum to test the contact mode of a steel wire rope, so that the measurement moving range is wide; a vortex type coil spring is arranged and can provide a certain tensioning force and returning force so as to ensure that the testing steel wire rope is tensioned as well as avoid disordering of the rope, and as a result, the tracking measuring accuracy is 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. ...
