Storage winch with function of measuring tension and length of cable

Abstract

The invention discloses a storage winch with a function of measuring tension and length of a cable. The storage winch comprises a cable storage cylinder, a support device, a cable guide device, a driving component, a cable arranging mechanism, a warning device, a power transmission communication interface connection device, a lightning attractor, a cable tension measuring device and a cable length measuring device. For cable length measurement, two lines of independent but related proximity switches are adopted for improving work reliability and measurement accuracy; for tension measurement, a pressure sensor is adopted, and force application pin rolls at two pin joint support seats between a cable guide support and a cable arranging sliding block are used for transmitting tension of the cable. The storage winch can be matched with a friction drive winch, is applicable to storage of a large volume of cables and arrangement of cables in order based on special support cables, has functions of measuring tension and laying length of the cable, protecting the cable and guaranteeing the operation safety, and meets special task requirements on large load, good safety, reliable operation, long cable laying distance, and the like.

Description

technical field [0001] The invention relates to a winch, in particular to a cable storage winch with the functions of cable tension measurement and cable length measurement. Background technique [0002] Ordinary winches often use cables and wire ropes to connect the load, and the wire ropes are wound on the winch cable drum, which is both a driving device and a cable storage device. When the cable used in the winch is a special cable or a composite cable (load-bearing, power transmission, and communication functions are integrated), since the skin is made of polyethylene plastic, it is easy to be squeezed and damaged when the multi-layer cable is unloaded. Therefore, in order to protect the cable from damage, the cable retraction drive must be separated from the cable storage function. The tension attenuation winch based on friction transmission drives the cable retraction, and the cable tension is greatly attenuated and then transmitted to the constant torque driven cable ...

AI Technical Summary

Problems solved by technology

Practical application shows that this method of cable length measurement will bring certain measurement errors. Due to the high tension of the cable wound on the driving winch, it will cause a certain extension and deformation of the cable, and because the driving winch drives the cable through friction, friction drives During the process, there may be a slight slip between the winch rope groove and the cable. When the balloon is lifted into the air at a height of 2000 meters, it will cause a cumulative cable length measurement error of about 10-20 meters during the recovery process.
