Abstract

The invention discloses an automatic tensioning control device and a control method, and belongs to the technical field of machinery. The device comprises a potentiometer, a controller, a proportionalsolenoid valve and an electromagnetic reversing valve, and the potentiometer is used for receiving a gear set by a user and sending a setting instruction corresponding to the gear set by the user; the controller is used for receiving the setting instruction sent by the potentiometer, issuing an adjusting instruction corresponding to the received setting instruction to the proportional solenoid valve and issuing a cable collecting instruction to the proportional solenoid; the electromagnetic reversing valve is used for receiving a cable collecting instruction sent by the controller and makingan oil inlet of the electromagnetic reversing valve communicated with a work oil opening, wherein the work oil opening is an oil opening, controlling a hydraulic motor to collect a cable, of the electromagnetic reversing valve; the proportional solenoid valve is used for receiving the adjusting instruction sent by the controller and adjusting the valve opening of the proportional solenoid valve into the valve opening corresponding to the adjusting instruction, and the valve opening of the proportional solenoid valve is used for controlling the bearing capability of the hydraulic motor. The automatic tensioning control device can automatically control the cable to be tightened.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an automatic tension control device and a control method. Background technique [0002] Offshore platform (English: offshore platform) is a structure that provides production and living facilities for offshore drilling, oil production, transportation, observation, navigation, construction and other activities. Anchoring, supply) and other auxiliary ships for towing navigation. [0003] The towing machine is the key equipment for the towing operation on the three-purpose workboat, mainly including the drum and the cable wound on the drum. The towing machine adopts electro-hydraulic drive, and the motor drives the main pump station to provide power for the hydraulic motor, so that the hydraulic motor drives the drum to rotate through the transmission device (generally including high-speed gear set, clutch, and low-speed gear set) to realize the retraction and release of ...
