Abstract

An automatic tensioning device for belt conveyor is suitable for long-range covneyor or a rubber belt conveyer, of which belt has a large extension rate. It achieves a large regulative range, an accurate control of tension force, and stable adjustment. The system consists of a tension monitor, a hydraulic device and a hydraulic hoist. The tension monitor comprises a detecting cylinder, a pressure sensor, a shutoff valve and a pressure meter. The hydraulic device comprises a pump, a reversing solenoid valve, a overflow valve, a manual valve, a hydraulic one-way valve, a proportional reversing valve, a one-way throttle valve, a one-way valve, a throttle valve, a tank, and oil-way. The outlet of the pump is respectively connected with the tension monitor, the cylinder and the driving circuit of the hydraulic hoist via the one-way valve.

Description

technical field

[0001] The invention relates to an automatic tensioning device for a belt conveyor, in particular to an automatic tensioning device which adopts a hydraulic winch to tension the belt. Background technique

[0002] The belt tension control device is the main component of the belt conveyor. Its function is to ensure that the belt has sufficient tension when the conveyor is working, and to ensure that there is a gap between the belt and the drive roller during starting, braking and normal operation. The required friction without slipping, and at the same time limit the sag of the tape between the supporting rollers to prevent the tape from spilling. At present, most of the belt conveyor tensioning devices used in China use hydraulic cylinders as tensioning elements. Although this hydraulic cylinder tensioning device can adjust the tension of the belt, it can meet the tension required by the belt during starting, braking and normal working conditions. Different ...
