Dual mode drive brakeable device for belt conveyor

Abstract

The invention relates to a dual-mode drive brake device of a belt conveyor. The dual-mode drive brake device of the belt conveyor comprises a hydraulic drive roller and a motor drive roller; a rotaryshaft of the motor drive roller is connected with a speed reducer through a coupler; the speed reducer is connected with a drive motor; the hydraulic drive roller is connected with a hydraulic motor;the hydraulic motor is connected with a planet gear gearbox; the planet gear gearbox and the hydraulic drive roller are fixed; a middle shaft of the planet gear gearbox is provided with a hydraulic brake; the hydraulic motor is connected with a hydraulic station; the hydraulic station comprises an oil tank, a power oil path and an electro-hydraulic directional control valve; one end of the power oil path is connected with the electro-hydraulic directional control valve; the other end of the power oil path is connected with the oil tank; a brake oil cylinder is connected with a brake oil path;and the brake oil path and a main control oil path are connected with a PLC controller. The problem of unbalance of dual-unit drive power is solved, a hydraulic system can automatically adjust the output torque and rotation speed, and it is ensured that the output force and rotation speeds of drive units are the same completely; and effective brake can be conducted. The hydraulic system can absorbpart of impact loads.

Description

technical field [0001] The invention belongs to the technical field of belt conveyors, and in particular relates to a dual-mode driving brake device of a belt conveyor. Background technique [0002] A belt conveyor is a friction driven machine that transports material in a continuous manner. It is mainly composed of frame, conveyor belt, idler roller, roller, tensioning device, driving device and so on. The traction force of the belt conveyor is transmitted through the friction between the drive roller and the belt, and the drive roller is driven by the drive device. The drive device is actually an energy conversion device, which can be divided into many types according to the possible conversion methods of energy. At present, the commonly used method is dual-motor drive. In an ideal situation, the power distribution ratio is the same as the driving force distribution ratio. However, due to differences in the manufacturing and installation errors of the rollers in actual si...

Problems solved by technology

At present, the commonly used method is dual-motor drive. In an ideal situation, the power distribution ratio is the same as the driving force distribution ratio. However, due to differences in the manufacturing and installation errors of the rollers in actual situations, the motor power load of the two rollers is unbalanced, which is serious. Sometimes it will cause one of the motors to overload and even be damaged, so a dual-mode drive with power balance is required
