Problems solved by technology

[0004] When the cable winch recovers the cable, if the cable is in a slack state (often exists), the cable wound on the winch is in a fluffy state. Once there is tension, the cable is bound to be pulled from the outer layer into the inner layer, which destroys the winding layer and affects The release of the cable is very easy to cause damage to the cable, and also affects the realization of automatic cable discharge; when the cable winch releases the cable, if the cable is also in a loose state, the released cable is often piled up in the winch or in the cable channel
At present, for the underwater robot cable winch, the tension control is mostly spring compensation type, the main disadvantage is that the structure is relatively large, the adjustment range is small, and there is no control advantage of electro-hydraulic integration

Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] The invention consists of two parts: tension control and counting, wherein the tension control part is driven by hydraulic pressure and has two shaft systems, one is a driving wheel shaft system, and the other is a driven wheel shaft system, and the driving wheel shaft system is installed on a fixed support. On the support frame formed by connecting with the chassis, the driven wheel shaft is mounted on the swing support frame formed by the hinged connection between the rocker arm and the rocker arm support fixed on the chassis; the cable is always clamped to the driving wheel and the driven wheel Between them, and enter the cable winch through the guide cylinder; the extension end of the piston rod of the hydraulic cylinder is hinged with the rocker arm, and the tail end of the hydraulic cylinder is hinged with the tailstock of the hydraulic cyli...

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...
