Control device and control method for follow-up operation of railway material transport vehicle and screen cleaning machine

Abstract

The invention relates to railway ballast cleaning work, in particular to a control device and method for follow-up operation of railway material transport carts and a ballast cleaning machine. According to the device and method, a coupling work mode is adopted, the railway material transport carts work along with the ballast cleaning machine synchronously, and automatic control is achieved. The control device comprises a ballast cleaning machine follow-up controller and material transport cart follow-up controllers, wherein the ballast cleaning machine follow-up controller is installed on the ballast cleaning machine, the material transport cart follow-up controllers are installed on the material transport carts, and the ballast cleaning machine follow-up controller is connected with the material transport cart follow-up controller through wireless signals. According to the control device and method for follow-up operation of the railway material transport cart and the ballast cleaning machine, various operation signals of the ballast cleaning machine are collected, feedback signals of the material transport carts are worked out in a wireless data transmission mode, and power of the material transport carts is controlled and fully utilized.

Description

technical field [0001] The invention relates to railway screen cleaning operations, in particular to a railway material transport vehicle and screen cleaning machine follow-up operation control device and control method that adopts a linked operation mode, and a material transport vehicle works synchronously with a screen cleaning machine to realize automatic control. Background technique [0002] During the railway cleaning operation, a large amount of dirt that needs to be discarded will be generated, and new ballast must be added at the same time. In the cleaning operation, the purpose of the railway material transport vehicle is to provide new ballast for supplementation. dirt. With the improvement of the operating efficiency of the railway screen cleaner, the material transport vehicle has a heavy load, and is generally equipped with its own driving force. Each operation requires several material transport vehicles to follow the operation. [0003] At present, there is...

AI Technical Summary

Problems solved by technology

There are two current operating modes. The first one is that the material transport vehicle is disconnected from the screen cleaning machine. An operator is required to observe the distance from the material transport vehicle to the screen cleaning machine, and adjust the running speed and screen cleaning through the knob in real time. Machine matching; this mode can avoid the power loss and damage of power transmission parts caused by the dragging of the material transport vehicle by the screen cleaning machine, but it requires an additional uncoupling operation when arriving at the scene, which requires high operating requirements for the on-site personnel and has certain hidden dangers , at the same time, the material transport vehicle cannot respond in time when the cleaning machine is in an emergency stop operation

The second type is that the material transport vehicle does not output power, and is dragged by the screen cleaning machine after being connected. This mode can reduce the labor intensity of the on-site operators, but it will lose the power of the screen cleaning machine, and it will not work when the load is heavy. There is a hidden danger of damage to the power transmission parts of the screen cleaner

[0004] In short, there are currently two modes for the material transport vehicle to follow the cleaning machine. One has the problem of difficult on-site operation and high requirements for the operator's skills, and the other has narrow application range, which may cause power loss or component damage to the cleaning machine.
