Tension control and counting derice

Abstract

A tension controlling and counting device for controlling the tension of electric cable used for underwater robot and counting the length of said electric cable is composed of a drive wheel-axle unit installed on the supporting frame consisting of fixing supporter and bottom plate, a driven wheel-axle unit installed on the swinging supporter frame consisting of rocker and its supporter, a cable winder, a hydraulic cylinder with piston, a magnetic proximity switch on said rocker, and a permanent magnet attached on the driven wheel.

Description

technical field

[0001] The invention relates to robot technology, in particular to a tension control and counting device suitable for providing proper tension for cables to ensure reliable operation of an underwater robot umbilical cable (cable for short) retracting and unwinding winch. Background technique

[0002] Practice has proved that the cable winch can successfully complete the mission of retracting and unwinding cables only under certain tension conditions.

[0003] The underwater robot is a special robot that operates in the underwater environment. When the underwater robot is operating, in order to ensure that the underwater robot is limited by its cables as much as possible, the released cables are long. Therefore, the cables are often in a slack state. Even during the retraction and retraction process of the underwater robot, its cables are often in a slack state; in order to maintain the proper cable retraction length, the cable winch must retract and retract t...
