Abstract

The invention discloses a safety protection device suitable for belt transmission. The device comprises a fixed plate, wherein an electromagnet I, a large belt wheel, a torque sensor, a motor and a PLC (Programmable Logic Controller) are arranged on the fixed plate, a small belt wheel on an output shaft of the motor is connected with the large belt wheel through a belt, and the torque sensor is also arranged on an output shaft of the motor. The invention further discloses a control method of the safety protection device suitable for belt transmission. When accidents such as power failure, beltbreakage and the like happen, by controlling the on-off of the current of the electromagnet, the electromagnet locks a driven belt wheel, so braking of a driven part mechanism is realized, and a problem that when the power is suddenly cut off or a belt is broken, if a load exists on the driven side and a corresponding safety protection device does not exist, safety accidents are possibly caused is solved.

Description

technical field [0001] The invention relates to the field of belt transmission in mechanical motion, in particular to a safety protection device and control method suitable for belt transmission. Background technique [0002] In the mechanical transmission system, the belt drive consists of a belt (including flat belt, V-belt, synchronous belt, etc.) and a driving pulley and a driven pulley installed on the driving shaft and the driven shaft. Belts on pulleys transmit motion and power between two or more shafts by means of friction or meshing between them. Belt transmission is widely used in modern machinery because of its simple structure, stable transmission, low cost, no need for lubrication, and shock absorption. There is a load, and if there is no corresponding safety protection device, it may also lead to safety accidents. Contents of the invention [0003] Technical issues resolved [0004] Aiming at the deficiencies of the prior art, the present invention provid...
