Description

Technical Field

[0001] This application relates to the field of track maintenance technology, and more specifically, to a track grinding and decontamination removal construction method. Background Technology

[0002] To improve track quality and ensure safe train operation, it is necessary to use rail grinding machines for grinding, maintenance, and upkeep of online rails. Grinding newly built tracks can correct manufacturing tolerances and construction errors, shorten the wheel-rail break-in period, and extend wheel-rail service life; it can eliminate surface defects such as burrs and rust on the new rail surface, improve the smoothness of the rail working surface, improve the new rail surface, reduce train noise, improve passenger comfort, and delay the occurrence of rail defects; for existing lines, regular grinding can eliminate and delay the development of corrugation, eliminate the contact fatigue layer on the rail surface to prevent peeling and spalling, and grinding the cross-section can also improve wheel-rail contact conditions and reduce contact stress.

[0003] When the grinding machine is in operation, it generates a large amount of iron filings and dust. The iron powder absorption device on the grinding machine cannot completely absorb the iron filings and dust on the surface of the track bed, and a lot of iron filings and dust will remain on the railway track bed. It needs to be cleaned in time, otherwise it may damage the railway equipment.

[0004] Currently, the grinding operation combines grinding vehicles with manual cleaning. Within a single track maintenance window, the grinding vehicle performs the grinding operation, returns to the base, and then track cleaning personnel clean up the iron filings and powder left on the track bed surface. This combined approach has drawbacks. Because time must be allocated for manual cleaning, the grinding vehicle's operating time within a single maintenance window is short, resulting in low track grinding efficiency. Furthermore, manual cleaning requires a large number of personnel; for example, on the Tianjin-Qinhuangdao Railway, 10 people are needed per kilometer of grinding section, which is labor-intensive and inefficient. For longer tracks, manual cleaning and waste removal are very difficult, and an excessive number of personnel also poses significant safety hazards. Summary of the Invention

[0005] To address one of the aforementioned technical deficiencies, this application provides a method for grinding and vacuuming rail tracks. This method utilizes existing rail grinding and vacuuming vehicles, enabling fully automated and unmanned grinding and cleaning operations.

[0006] According to a first aspect of the embodiments of this application, the above-mentioned method for grinding and vacuuming track lines includes the following steps:

[0007] Construction preparation steps: The grinding truck and vacuum truck are moved to the work area;

[0008] Grinding operation steps: The grinding machine lowers the grinding device and runs back and forth between the start and end of the work area to carry out the grinding operation;

[0009] Vacuuming operation steps: When the grinding truck runs to the end where the vacuum truck is located, the vacuum truck lowers the sewage collection device. When the grinding truck turns back from the end where the vacuum truck is located, the vacuum truck follows the grinding truck to perform the sewage suction operation.

[0010] The track grinding and cleaning method provided in this application has the advantages of simple construction organization, which can effectively reduce maintenance time during track maintenance windows and reduce the amount of manpower. In addition, the grinding and cleaning method can achieve fully automated grinding and cleaning, reduce or eliminate track cleaning personnel, and reduce labor intensity, which is in line with the green development concept of "safety with no people and safety with fewer people" and "safety with technology". Finally, the grinding and cleaning method can efficiently absorb grinding iron powder, dust and other dirt, protecting the natural environment and human health. Attached Figure Description

[0019] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0020] In the process of developing this application, the inventors discovered that in existing railway maintenance work, the cleaning work after the grinding machine has finished grinding is still done manually. That is, within a maintenance window, the grinding machine first performs the grinding operation, and after the grinding is completed, the grinding machine returns to the base, whereby track cleaning personnel clean up the iron filings and powder left on the track bed surface. This combination of grinding machine and manual cleaning has low track grinding efficiency; it requires a lot of manpower and has very low cleaning efficiency; for long tracks, manual cleaning and disposal of dirt is very difficult, and too many cleaning personnel also pose significant safety hazards.

[0021] To address the aforementioned problems, this application provides a method for grinding and vacuuming railway tracks. This method utilizes a grinding vehicle and a vacuum vehicle. The grinding vehicle is equipped with a grinding device that is retracted when not in operation and lowered to contact the rail surface during operation, performing grinding work simultaneously with the movement of the automatic grinding vehicle. The vacuum vehicle is equipped with a waste collection device, which includes a blower, a suction fan, and a waste collection device. The blower generates a high-speed airflow that blows up waste from the railway track surface, while the suction fan draws the waste-laden airflow into the waste collection device. The airflow, mixed with waste, is then discharged into the air after settling and filtration, thereby achieving the purpose of cleaning the railway tracks. This combined blowing and suction method has the advantages of high operating efficiency and low power consumption, making it particularly suitable for mobile vehicles and effectively cleaning waste from the railway track surface. Both the grinding vehicle and the vacuum vehicle have mounting structures at both ends for mounting other locomotive frames. The structures of the grinding vehicle and the vacuum vehicle are existing technologies and will not be described in detail here.

[0022] Figure 1 A flowchart illustrating the track grinding and decontamination removal method provided in this application embodiment is shown below. Figure 1 As shown, this method for grinding and vacuuming tracks includes:

[0023] Construction preparation steps: The grinding truck and vacuum truck are moved to the work area;

[0024] Grinding operation steps: The grinding machine lowers the grinding device and runs back and forth between the start and end of the work area to carry out the grinding operation;

[0025] Vacuuming operation steps: When the grinding truck runs to the end where the vacuum truck is located, the vacuum truck lowers the sewage collection device. When the grinding truck turns back from the end where the vacuum truck is located, the vacuum truck follows the grinding truck to perform the sewage suction operation.

[0026] Before entering the work area, the grinding car and the vacuum truck are coupled together via a coupling device installed on their frames. The vacuum truck can be mounted in front of or behind the grinding car. To explain this more clearly and in detail, the application of the track grinding and vacuuming construction method provided in this application in these two mounting methods will be described below. Figure 2 This is a diagram showing a vacuum truck in operation. Figure 3 This is a flowchart of the operation process for a vacuum truck in front; see attached... Figure 2 In the diagram, the starting point of the work area is represented by A, and the ending point is represented by B. The area between line segments A and B constitutes work area 101, with the ending point B located in front of the starting point A. For example... Figure 2 As shown, before entering the work area, the vacuum truck 2 and the grinding truck 1 are connected together, with the vacuum truck 2 located in front of the grinding truck 1. The grinding truck 1 is equipped with a power structure that can drive the vehicle forward. The vacuum truck 2 may or may not have a power structure, or it may be equipped with a power structure that can drive the vehicle forward.

[0027] like Figure 3 As shown, the method for vacuuming and grinding the track in the work area, where the vacuum truck 2 enters in front of the grinding truck 1, includes:

[0028] Grinding truck 1 and vacuum truck 2 are coupled together and enter the work area 101, with vacuum truck 2 located in front of grinding truck 1. Grinding truck 1 and vacuum truck 2 stop and wait at the beginning of the work area.

[0029] Grinding truck 1 and vacuum truck 2 are uncoupled. Vacuum truck 2 runs to the end point B of the work area and stops to wait for further instructions.

[0030] The grinding vehicle 1 lowers the grinding device at the beginning of the work area and moves from the beginning of the work area to the end of the work area, and performs the first grinding operation during the operation.

[0031] After the first round of polishing, when the polishing vehicle 1 reaches the end of the work area, the vacuum truck 2 lowers the waste collection device and prepares to follow the polishing vacuum truck 2 to perform the waste suction operation.

[0032] Grinding vehicle 1 turns back from the end point B of the work area and moves from the end point B of the work area towards the start point A of the work area, and performs the second grinding operation during the operation.

[0033] During the second round of polishing, the vacuum truck 2 follows the polishing truck 1 from the end point B of the work area to the beginning point A of the work area, and performs vacuuming operations during the operation; at this time, the vacuum truck 2 and the polishing truck 1 are not connected and maintain a working distance, the distance of which is determined according to the needs of the construction site.

[0034] After the second round of polishing is completed, the polishing truck 1 and the vacuum truck 2 will travel to the starting point A of the work area one after the other. The polishing truck 1 and the vacuum truck 2 will stop working, retract their working devices, and stand by. The working devices refer to the polishing device on the polishing truck 1 and the polishing device and the waste collection device on the vacuum truck 2.

[0035] Grinding vehicle 1 performs ballast removal at the starting point A of the work area. After the ballast removal is completed, grinding vehicle 1 and vacuum truck 2 are coupled together and return to the base.

Figure 4 In the diagram, the starting point of the work area is represented by A, and the ending point is represented by B. The area between line segments A and B constitutes work area 101, with the ending point B located in front of the starting point A. For example... Figure 4 As shown, before entering the work area, the vacuum truck 2 and the grinding truck 1 are connected together, with the vacuum truck 2 located behind the grinding truck 1. Each of the vacuum truck 2 and the grinding truck 1 has a power structure that can drive the vehicle forward.

[0037] like Figure 5 As shown, the method for vacuuming and grinding the track in the work area, where vacuum truck 2 enters from behind grinding truck 1, includes:

[0038] Grinding truck 1 and vacuum truck 2 are coupled together and enter the work area, with vacuum truck 2 located behind grinding truck 1. Grinding truck 1 and vacuum truck 2 travel to the end point B of the work area and stop at the end point B to wait for further instructions.

[0039] Grinding truck 1 and vacuum truck 2 are uncoupled. Vacuum truck 2 moves to the starting point A of the work area and stops to wait.

[0040] Grinding vehicle 1 lowers the grinding device at the end point B of the work area and moves from the end point B of the work area towards the beginning point A of the work area, and performs grinding operations during the operation.

[0041] After the first round of polishing is completed, when the polishing vehicle 1 moves to the starting point A of the work area, the vacuum truck 2 lowers the waste collection device and prepares to follow the polishing vacuum truck 2 to carry out the waste suction operation.

[0042] Grinding vehicle 1 turns back from the starting point A of the work area and runs from the starting point A to the ending point B of the work area, carrying out grinding operations during the operation;

[0043] In the second polishing operation, the vacuum truck 2 follows the polishing truck 1 from the starting point A of the work area to the ending point B of the work area, and performs vacuuming operations during the operation.

[0044] After the second round of polishing is completed, the polishing truck 1 and the vacuum truck 2 drive to the end point B of the work area, stop working, retract the working device, and stop to wait for further instructions.

[0045] Grinding vehicle 1 performs ballast removal at the end point B of the work area. After the ballast removal is completed, grinding vehicle 1 and vacuum truck 2 are coupled together and return to the base.
