Abstract

The invention provides a soft starting device of a belt conveyor. The device comprises a three-phase asynchronous motor, a hydraulic torque converter, an automatic transmission and an electronic control unit; the three-phase asynchronous motor is connected with an input end of the automatic transmission through the hydraulic torque converter; an output end of the automatic transmission is connected with the belt conveyor; a belt speed sensor is arranged on a conveying belt of the belt conveyor; the automatic transmission comprises a gear selecting and shifting execution mechanism and a gear sensor; and the gear selecting and shifting execution mechanism, the gear sensor and the belt speed sensor are electrically connected with the electronic control unit. The device is simple in structure,high in transmission efficiency and convenient to maintain, and greatly reduces the cost.

Description

technical field [0001] The invention relates to a belt conveyor starting device, which belongs to the technical field of conveyors. Background technique [0002] As the most important modern bulk material conveying equipment, belt conveyor is widely used in electric power, metallurgy, chemical industry, coal, mining, port, building materials, grain and other fields. The movement of the conveyor belt carries out continuous conveying equipment for material conveying. [0003] The development trend of belt conveyors is long distance, high speed, large capacity and high power, but this brings a series of problems at the same time, such as: (1)) There is a large acceleration and acceleration when the belt conveyor starts The sudden change will cause a large dynamic load to each element, resulting in unstable system operation; (2) the belt conveyor is difficult to start, etc. SUMMARY OF THE INVENTION [0004] Aiming at the problems existing in the existing belt conveyors, ...
