Embodiment Construction

[0016] The present invention proposes a novel dual-drum balance driving device and its use method;

[0017] The PLC control system includes a torque sensor, a speed sensor, a motor, a hydraulic pump and a hydraulic cylinder; the torque sensor and the speed sensor are connected to the drum shaft; the motor is connected to the hydraulic pump, and the hydraulic pump is connected to the hydraulic cylinder;

[0018] The slider mechanism is fixed on the fixed frame 3 between the two rollers and driven by the hydraulic cylinder to move up and down;

[0019] The idler roller is installed on the idler groove on the slider mechanism;

[0020] The material holding box is arranged directly under the idler roller between the two rollers, and is used to load the sundries left by the idler roller to clean the conveyor belt.

[0021] The use process is:

[0022] In the first step, when the drum I7 and the drum II1 are working, the torque sensor and the speed sensor are input into the contro...

Abstract

The invention discloses a novel double-drum balanced driving device and a using method. The device comprises a PLC control system, a slide block mechanism, a carrier roller and a material bearing box, wherein the PLC control system comprises a torque sensor, a rotating speed sensor, a motor, a hydraulic pump and a hydraulic cylinder; the torque sensor and the rotating speed sensor are connected to a drum shaft; the motor is connected to the hydraulic pump, and the hydraulic pump is connected to the hydraulic cylinder; the slide block mechanism is fixed on a fixed rack between the two drums and is driven by the hydraulic cylinder to move up and down; the roller is mounted on a carrier roller groove on the slide block mechanism; the material bearing box is arranged right below the carrier roller between the two drums for loading sundries falling from a carrier roller sweeping conveyor belt. The device disclosed by the invention realizes power balance driven by the double drums, reduces imbalance of abrasion of the two drums, and achieves the purposes of reducing the loss and prolonging the service lives of the drums and the conveyor belt.

Description

Technical field: [0001] The invention relates to the field of mining machinery, in particular to a double-drum balance driving device and a using method of a belt conveyor. Background technique: [0002] The belt conveyor has a history of more than one hundred years. At present, the belt conveyor is constantly developing towards large capacity, long distance and high belt speed. Traditional belt conveyors transmit power through friction, so a single pulley drive cannot generate sufficient traction. At present, the common solution is to use the double rollers to drive separately, and increase the traction by increasing the wrapping angle. However, due to factors such as equipment manufacturing, installation errors, load changes, and uneven force on each drive roller conveyor belt, the load power of the motor will be unbalanced, which is not conducive to improving efficiency. When the load is severe, it may even cause accidents such as motor burnout. It is very important to ...
