Problems solved by technology

The belt conveyor uses the traditional winch to control the tension, but the process of controlling the tension through the winch not only slows the start-up response, but also is inconvenient to adjust the tension in real time. Belt and other conditions occur, which greatly affects the efficiency of the conveyor
[0003] The working conditions of the hydraulic control system of the traditional hydraulic winch are simple, the accuracy and real-time performance of the control process are poor, and the automatic control of the tension cannot be realized.
In addition, when the control system starts and stops, the impact force is relatively large and the response speed is relatively slow, so the conveying efficiency of the belt conveyor will be low, the energy consumption of the system will be large, and the failure rate will be high.

Abstract

The invention discloses a winch hydraulic control system achieving automatic tensioning and free reeling off. The winch hydraulic control system comprises an oil tank, an electric motor, a double pump and a motor, wherein the motor is connected with a winch drum; the winch hydraulic control system further comprises a pressure control system, an automatic reeling off control assembly, a braking system assembly and a controller; the pressure control system comprises a first pressure gauge, a pressure transmitter and a proportional overflow valve; the automatic reeling off control assembly comprises a one-way valve, a two-position hydraulic control reversing valve and a pilot overflow valve; the braking system assembly comprises a brake used for conducing braking on the motor and a brake valve group, and the brake valve group is composed of a magnetic exchange valve, an overflow valve and a second pressure gauge. The winch hydraulic control system is high in automation degree and capable of accurately achieving stepless control of a tensioning force of a belt conveyor in real time, impact of start and stop of a winch can be effectively reduced, and therefore the failure rate can be reduced; meanwhile, the winch hydraulic control system can achieve a rapid response of start of the winch, therefore, the conveying efficiency of the belt conveyor can be improved, and energy consumption can be effectively saved.

Description

technical field [0001] The invention relates to a hydraulic control system of an automatic tensioning and free-releasing winch, belonging to the technical field of winch hydraulic control systems. Background technique [0002] In material conveying machinery, winches are widely used as a tensioning device for belt conveyors. The belt conveyor uses the traditional winch to control the tension, but the process of controlling the tension through the winch not only slows the start-up response, but also is inconvenient to adjust the tension in real time. Belt and other conditions occur, which greatly affects the efficiency of the conveyor. [0003] The working conditions of the hydraulic control system of the traditional hydraulic winch are simple, the accuracy and real-time performance of the control process are poor, and the automatic control of the tension cannot be realized. In addition, when the control system starts and stops, the impact force is relatively large, and the...
