Problems solved by technology
[0002] The power system of the traditional mining underground scraper conveyor is that the motor drives the reducer, and the reducer drives the sprocket shaft group of the equipment to work. Since the sprocket shaft group needs to adjust the speed frequently and start and stop frequently, the frequent start and stop of the motor has a great impact on the power grid. The impact is large, and the large torque when starting and stopping causes great impact and vibration to the sprocket shaft group of the scraper conveyor, and the service life of the sprocket shaft group is short

An underground mine scraper conveyor driven by a hydraulic motor comprises a motor and a sprocket shaft group of a scraper conveyor, and further comprises a bidirectional variable constant power hydraulic pump, an oil tank and a constant displacement hydraulic motor, wherein the motor is connected with the hydraulic pump, the oil tank, the hydraulic pump and the hydraulic motor are respectively communicated with each other through oil pipes, the constant displacement hydraulic motor is driven by a closed hydraulic system, and an output shaft of the hydraulic motor is connected with the sprocket shaft group of the scraper conveyor. The underground mine scraper conveyor driven by the hydraulic motor adopts a hydraulic power system, the output torque and rotating direction of the hydraulic motor are adjusted through controlling the hydraulic pump, and accordingly, the speed regulation, starting, stopping and reverse rotating of the sprocket shaft group are controlled; the mechanical energy of the motor is converted into the oil pressure energy; the hydraulic motor has tha advantages of small volume, light weight and small movement inertia; and under the conditions of frequent starting and stopping, large starting torque, necessary speed regulation and reversing rotating, the sprocket shaft group is only influenced slightly.
Description
technical field [0001] The invention relates to a transportation device, in particular to an underground scraper conveyor driven by a hydraulic motor. Background technique [0002] The power system of the traditional mining underground scraper conveyor is that the motor drives the reducer, and the reducer drives the sprocket shaft group of the equipment to work. Since the sprocket shaft group needs to adjust the speed frequently and start and stop frequently, the frequent start and stop of the motor has a great impact on the power grid. The impact is large, and the large torque when starting and stopping causes great shock and vibration to the sprocket shaft group of the scraper conveyor, and the service life of the sprocket shaft group is short. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic motor-driven mining underground scraper conveyor with little impact on the power grid, small impact on the sp...
