Description

Technical Field

[0001] The invention belongs to the field of sanding of power-centralized EMUs, and in particular relates to an integrated sanding system and method for power-centralized EMUs. Background Art

[0002] The existing train preparation operations include sanding, unloading, water washing, etc. With the development of railway technology and the lengthening of locomotive routes, the increase in the number of locomotive sets and the increase in locomotive preparation cycles, the existing preparation equipment has a lot of problems:

[0003] 1. The existing maintenance facilities cannot meet the needs of centralized power EMU maintenance. The existing technology can only be sanded manually, and there is no integrated sanding equipment;

[0004] 2. Traditional maintenance facilities cannot accommodate the needs of centralized power EMUs and ordinary passenger cars. As centralized power EMUs gradually replace locomotives and rolling stock, making full use of existing locomotive and vehicle depot resources and compatible integrated development are inevitable trends;

[0005] 3. There is a lack of new facilities and new models for comprehensive and integrated operations. The existing maintenance facilities and management models are inefficient, and the existing operation models of separate institutions, departments, and personnel cannot avoid mutual interference in maintenance operations;

[0006] 4. The existing maintenance setting layout has problems such as shortened on-site service life, unreasonable occupation of public resources, and poor maintenance environment.

[0007] The existing sand conveying process mainly includes:

[0008] 1. Artificial conveying sand loading process plan;

[0009] 2. Artificial sand loading process plan with equipment-assisted transportation;

[0010] 3. Mobile semi-automatic sand conveying process plan;

[0011] 4. Fixed semi-automatic sand conveying process solution.

[0012] There are the following problems:

[0013] 1. The manual sand conveying process has low efficiency in single operation, which has a great impact on the labor intensity of the workers and poses a great safety hazard;

[0014] 2. The manual sand loading method with equipment-assisted transportation mainly uses forklifts to assist workers in transferring sand boxes, which greatly reduces the time and efficiency of workers in the handling process. However, this solution has high requirements for the site, and there are safety hazards between people and forklifts and high transportation costs.

[0015] 3. The mobile semi-automatic sand loading equipment greatly improves the efficiency of sand loading operation, but its adaptability is not strong and it cannot cross tracks or platforms. In addition, since the sand loading trolley is battery-driven, it has low power and low stability, and the problem of human inhalation of exhaust gas is not solved during operation;

[0016] 4. Although the fixed semi-automatic sanding process has been developed for many years, most systems have many limitations due to various factors and still cannot be widely promoted and applied. Summary of the invention
