The invention discloses a self-compensating controllable braking device which comprises a supporting roller, the two sides of the supporting roller are provided with a pneumatic cylinder, the pneumatic cylinder is connected with an aerodynamic device, the top of a piston rod of the pneumatic cylinder is tightly contacted with a roller body of the supporting roller, one side (contacted with the supporting roller) of the pneumatic cylinder is provided with a cleaning device, and the aerodynamic device is provided with a pressure control system; the self-compensating controllable braking device is also provided with a pressure monitoring device and a fault alarming device, and the pressure control system controls the aerodynamic device; and the aerodynamic device achieves an effect of adjusting the braking torque of the self-compensating controllable braking device through controlling the magnetostrictive displacement of the piston rod of the pneumatic cylinder. By using the self-compensating controllable braking device disclosed by the invention, the reliability of a conveyor is increased, the service life of the conveyor is prolonged, and the application and maintenance fees of theconveyor are reduced.
Description
technical field [0001] The invention relates to the technical field of rollers used in material conveying equipment such as belt conveyors, which enables the rollers of the belt conveyor to have comprehensive performance indicators such as controllable braking, pressure detection, and fault alarms, thereby realizing the reliability of the belt conveyor. Parking brake. Background technique [0002] The belt conveyor is mainly composed of rollers, brackets, conveyor belt drive devices, etc. The roller is one of the main components of the belt conveyor and is the most widely used. Due to the difference in belt speed and capacity, the dimensions of the idler rollers are different. Commonly used types of idlers are: buffer idlers, parallel idlers, self-aligning idlers, etc. [0003] At present, the belt conveyor rollers at home and abroad mainly include the following varieties [0004] 1. Parallel roller [0005] For return branch support conveyor belt [0006] 2. Buffer rol...
