Problems solved by technology

The 16 PGM-48 rail grinding cars introduced in my country in the early stage were mainly produced by Panjero Jackson Company of the United States. Most of them have a service life of more than 15 years. Problems such as difficulty in purchasing accessories seriously restrict the use of grinding vehicles, resulting in idle and waste of equipment

Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] Such as figure 1 , The electrical control system of the grinding car is developed on the basis of the large-scale road maintenance machinery network control platform of Zhuzhou CSR Times Electric Co., Ltd. The control system of the whole vehicle is composed of the subsystems of 3 vehicles connected by local Ethernet, and the network control system of each vehicle is composed of a distributed electrical system based on the expansion of multiple CAN bus modules to complete the control of all electrical signals. Control and feedback collection to achieve the purpose of mechanical, electrical and hydraulic control. The control subsystem of each car is functionally divided into a grinding operation control system and a hydraulic travel control system.

[0014] Such as figure 2 , No. I car and No. 3 car of PGM-48 rail grinding car each have 4 hydraulic pumps direct...

Abstract

An electrical control system for a PGM‑48 rail grinding car, including hydraulic travel control and grinding operation control, which breaks through low-speed constant-speed hydraulic travel control technology and constant power grinding control technology, and can replace the control system of earlier imported grinding cars with equal functions. The electrical control system solves the problem that the electrical system of the grinding car introduced in the early stage cannot be repaired and matched, and provides the possibility for the matching of the electrical system of the domestic grinding car.

Description

Technical field [0001] The invention relates to an electrical control system of a PGM-48 rail grinding car, which is suitable for the mechanical field. Background technique [0002] With the implementation of railway speed increase and heavy load, the requirements for line maintenance are getting higher and higher, and rail grinding has become an important means of daily maintenance of railways, especially high-speed railways. At present, the rail grinding vehicles used in China are all imported or jointly produced by domestic factories and foreign parties, and the cost is high. Among them, the electrical control system is the core part of the rail grinding vehicle, and foreign manufacturers have not transferred it. To truly realize the localization of rail grinding vehicles, it is necessary to break through the bottleneck of the electrical control system. The 16 PGM-48 rail grinding cars introduced in my country in the early stage were mainly produced by Panjero Jackson Co...
