Winch for online test of automatic cable arranging tension

Abstract

The invention discloses a winch for the online test of automatic cable arranging tension. When the winch works, due to the action of a cable pressing mechanism, a working cable is controlled within the certain range and is wound around a reel or taken out from the upper part of the reel so as to ensure that the born pressure of the cable is uniform; and meanwhile, by depending on a rotary tongue capable of freely rotating on a cable arranging mechanism, the working cable is uniformly, safely and reliably wound around the reel. Simultaneously, according to the winch disclosed by the invention, rollers and the cable arranging mechanism of the winch are integrally assembled, so that the tension born by a cable can be monitored in real time in a working process and the regular operation of a water device can be ensured. An upper support and a lower support of the cable arranging mechanism are connected by strength bearing steel balls so that the upper support has the certain displacement under the condition of ensuring the connection strength, and the unbeneficial influence caused by the fluctuation of the working cable due to surge is eliminated or reduced; and a contact surface of the upper support and a load sensor is designed to be spherical, so that during working, a stress position of the load sensor or a position of a stress point can keep changeless.

Description

technical field [0001] The invention relates to an automatic cable tension online testing winch. Background technique [0002] At present, most of the retracting winches used for offshore cables adopt automatic cable unwinding technology for cable retraction, and also have the function of cable tension test. However, in the actual application and operation process, due to the weather, the swell is too large. At this time, uneven cable arrangement often occurs when the cable is taken up, and the measured data is also inaccurate. Because most of the tension test methods used in marine cable winches are tension gauges or tension sensors, which are connected to the cable with sheaths or clamps, it is difficult to monitor the tension of the cable in real time as the length of the cable retracts and unwinds. The size of the value. In case of bad weather or improper installation, the cable may be damaged, or the tension of the cable suddenly increases unexpectedly and the stress ...
