Speed control system and shunting system for shunting equipment

Abstract

The invention provides a speed control system and a shunting system for shunting equipment. The speed control system comprises a position detection device, a control device and a frequency conversion device which are connected with one another, wherein the position detection device is used for detecting a current position of the shunting equipment and transmitting the current position to the control device; the control device is used for receiving the current position of the shunting equipment and outputting a speed control signal corresponding to the current position according to a position-speed corresponding curve for the shunting equipment to the frequency conversion device, wherein the position-speed corresponding curve is obtained by fitting according to the initial speed, the initial position and a preset stepping parameter of the shunting equipment; and the frequency conversion device is used for receiving the speed control signal and controlling the rotation speed of a motor of the shunting equipment according to the received speed control signal so as to control the speed of the shunting equipment. The speed control system and the shunting system provided by the invention can automatically control the advancing of the shunting equipment and has higher safety.

Description

technical field [0001] The present invention relates to the field of control for dumper systems, and more particularly relates to a speed control system and a shunting system for shunting equipment. Background technique [0002] The dumper system is a complete set of equipment used for the unloading of trains for the transportation of bulk materials on railways. The application places are mainly concentrated in coal unloading operations in ports. According to the mechanical function, the dumper system can be divided into shunting equipment, unloading equipment, feeding device and auxiliary equipment. Among them, the car shunting equipment also includes a pusher and a positioning car. The pusher and the positioning car hand over and work continuously to complete the forward movement of the carriage, and adjust the vehicle to the designated position according to the work requirements. During the operation process, after the two-section heavy vehicles at the handover position ...

AI Technical Summary

Problems solved by technology

[0003] The running speed of the positioning car and the trolley machine in the existing shunting equipment is mostly controlled by humans, and the operating safety largely depends on the operator's experience and proficiency, which has high requirements for the operator's work. Therefore, the current The speed control method is labor-intensive and has potential safety hazards
