Description

Technical Field

[0001] The present application relates to a track maintenance machinery control technology, and in particular to a ballastless track support platform grinding operation method. Background Art

[0002] At present, with the increase in the mileage of ballastless high-speed railway lines in my country and the increase in the length of time they have been put into operation, the daily maintenance and repair of ballastless track lines is extremely urgent. In order to ensure the normal and safe operation of high-speed trains on the lines, the track quality index TQI value is required to be higher and higher. A TQI value that is too high is very detrimental to the safety of high-speed driving. The TQI value will be affected when the roadbed of high-speed railways settles or arches. After the TQI value changes, repairing and maintaining the high-speed railway to restore the TQI value is a necessary means to ensure the safety of high-speed driving.

[0003] For ballastless track, when the track quality index value changes due to small settlement and arching, the rail fastener system can be adjusted to restore the track quality index value to ensure driving safety. For sections with large arching, which have exceeded the adjustment range of the rail fastener system, the method of dismantling the ballast plate and roadbed under the sleepers and rebuilding them can be adopted, or the track bearing platform can be re-grinded and repaired to ensure that the repaired track bearing platform can meet the line quality requirements for high-speed train operation. The grinding and maintenance of the track bearing platform requires high contour accuracy, which is difficult to meet with manual grinding. Therefore, the use of mechanized profiling grinding for construction operations has become an inevitable choice.

[0004] Currently there is no mature control system and control method for the rail support platform grinding device.

[0005] In view of this, this application is hereby filed Summary of the invention

[0020] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0021] Embodiment 1

[0022] This embodiment provides a method for grinding a ballastless track support rail. In practical applications, the method can be implemented by a computer program, such as application software, etc.; or, the method can also be implemented as a medium storing relevant computer programs, such as a USB flash drive, a cloud disk, etc.; or, the method can also be implemented by a physical device integrated or installed with relevant computer programs, such as a chip, a mobile smart device, etc.

[0023] like Figure 1 and Figure 2 As shown, the present application provides a ballastless track support rail grinding method, comprising:

[0024] Step 101, obtaining data information of the rail support platform to obtain a total grinding amount D of the rail support platform;

[0025] The data information of the track support platform can be established in advance based on the actual data of the track support platform, or the commonly used track support platform data can be directly used.

[0026] In a specific implementation, the total grinding amount D of the rail support platform can be 0-40 mm or any value above.

[0027] Step 102, according to the single grinding depth capability d of the grinding device, the total grinding amount is decomposed into N=D / d, where N is the number of grinding times;

[0028] Specifically, the total grinding amount D of each rail support is decomposed into N single grindings according to the single grinding depth capacity d of the grinding device, where N=D / d, and the last grinding amount is dn≤D / N.

[0029] Step 103, processing the single grinding depth capability d, the number of grinding times N and the total grinding amount D of the grinding device to establish a preset grinding program;

[0030] Step 104, grinding the rail support of each sleeper in turn according to a preset grinding program.

[0031] In the specific implementation, this application takes three sleepers and six rail supports as an example. After the tool setting is completed, the different grinding amounts of the six rail supports, such as D1, D2, D3, D4, D5, and D6, are input in the operating section. The system automatically recognizes and decomposes them, and decomposes them into N=D / d to carry out grinding of two rail supports for each pair of sleepers. The grinding process is fully automated, which can solve the complex working conditions required by different grinding amounts of sleepers and improve the grinding construction efficiency. The use of this method for rail support grinding construction can efficiently solve the grinding construction of rail support with complex requirements.

[0032] Specifically, the grinding amount D of the rail support platform can be any value of 0-40mm or above, and the single grinding depth d can be set to any value such as 5mm / 8mm / 10mm, which is determined according to the actual capacity of the grinding device or the material of the rail support platform on site.

[0033] As a specific implementation, before grinding the rail support platform of each sleeper in turn according to a preset grinding program, it also includes adjusting the position of the grinding device and the rail support platform along the X, Y and Z directions.

[0034] Specifically, adjusting the positions of the grinding device and the rail support platform along the X, Y and Z directions includes:

[0035] (1) Along the X direction, the grinding device is self-propelled and positioned;

[0036] (2) Adjust the position along the Y direction so that the alignment shoe is aligned with the outer contour of the rail support;

[0037] (3) adjusting the position in the Z direction so that the grinding wheel of the grinding device is aligned with the inner contour of the rail support;

[0038] (4) The position is adjusted along the Y direction and the Z direction so that the grinding wheel of the grinding device can adapt to the rail bottom slope.

[0039] As a specific implementation method, the rail support of each pair of sleepers is polished, and then the method further includes:

[0040] The grinding wheel of the grinding device is raised to the tool setting position and quickly moves the stroke b to the grinding starting point of the rail support platform of the next rail sleeper.

[0041] As a specific implementation method, grinding the rail support of each pair of sleepers includes:

[0042] The first grinding is performed on the two rail supports of each pair of sleepers, and the grinding depth is d; after the first grinding is completed, it is lifted by d and returned to the starting point of the first sleeper; then the second grinding is performed, and the total grinding amount of the two rail supports of the sleepers is completed in sequence.

[0043] Further, as a specific implementation manner, the last grinding amount of the grinding device is dn≤D / N.

[0044] Further, as a specific implementation method, N=D / d, when there is a remainder after division, polishing is performed according to the remainder.

[0045] As a specific implementation method, the position is adjusted along the Z direction so that the grinding wheel of the grinding device is aligned with the inner contour of the rail support platform; including:

[0046] (1) Adjust the vertical position of the grinding wheel along the Z direction so that the grinding wheel profile fits the rail support;

[0047] (2) Adjust the rotation of the grinding wheel head to eliminate the gap between the grinding wheel and the rail support platform contour, so that the grinding wheel is completely consistent with the inner contour of the rail support platform to complete the tool alignment.

[0048] In the specific implementation, as a specific implementation method, a grinding device is placed on the adjacent track plate of the upper arch disease construction section, and the track support platform of the upper arch disease construction section is ground.

[0049] As a specific implementation method, the embodiment of the present application provides a method for grinding the track support platform of a ballastless track; during implementation, the track support platform grinding vehicle group can enter the upper arch disease construction section from the adjacent line and stop near the construction section. The vehicle group is equipped with a track support platform grinding device, and the grinding device is placed on the adjacent line track plate by a mechanical mechanism set on the vehicle group to start the track support platform grinding operation.

[0050] Take the grinding amount D1, D2, D3, D4, D5, and D6 of six rail supports of three rail sleepers as an example; by decomposing the total grinding amount D of each rail support, according to the single grinding depth capacity d of the grinding device, the total grinding amount is decomposed into N single grindings to achieve N = D / d, and the last grinding amount is dn ≤ D / N. After the tool setting is completed, the different grinding amounts of six rail supports, such as D1, D2, D3, D4, D5, and D6, are input in the operation section, and the system automatically recognizes and decomposes them, decomposing them into N = D / d to carry out the grinding of two rail supports for each pair of sleepers, and the grinding process is fully automated.

[0051] like Figure 3 and Figure 4 As shown, the specific construction method is:

[0052] (1) The grinding device is suspended on the ballastless track slab, and the four running wheels fall on the edge of the track slab. The running wheels are manually checked for accuracy. In the specific implementation, the grinding device guide and clamping device are quickly installed to prevent the running device from falling off the track, and the hydraulic pipeline is manually connected. The guide and clamping devices adopt a quick-connect connection method, which can be quickly disassembled and assembled. The grinding device is positioned when it reaches the mark line, and the next step is to align the shoe and the rail support platform; if it does not reach the mark line, the grinding device is repeatedly positioned.

[0053] (2) Align the shoe and the rail support and lift them up to a distance of H;

[0054] Specifically, the position is adjusted along the X direction, and according to the requirements of the rail platform to be polished, the polishing device is remotely controlled to move to the working position that needs to be polished, and the front and rear alignment shoes correspond to the positions of the rail platform;

[0055] Adjust the position along the Y direction, use the alignment device to align with the outer arc of the rail support shoulder, and lift the grinding device to align.

[0056] Specifically, when the alignment effect is not good, the jacking and alignment can be repeated. After the jacking and alignment are completed, the clamping cylinder of the clamping device is operated to clamp the track plate.

[0057] (3) Tool alignment to ensure that the grinding wheel is aligned with the inner contour of the rail support

[0058] Specifically, the grinding wheel mechanism is remotely or mechanically operated to adjust the rail moving mechanism along the X direction so that the grinding wheel moves to a starting position above the rail support platform to be ground;

[0059] The grinding wheel mechanism is remotely or mechanically operated to adjust the grinding wheel lateral moving mechanism along the Y direction so that the two "inverted eight-shaped" inclined surfaces of the grinding wheel are aligned with the "inverted eight-shaped" inclined surfaces of the rail support platform;

[0060] The grinding wheel mechanism is remotely or mechanically operated to adjust the grinding wheel along the Z direction so that the contour of the grinding wheel fits the rail support platform.

[0061] In specific implementation, in order to eliminate the gap between the grinding wheel and the rail support platform, so that the grinding wheel and the inner contour of the rail support platform are completely matched, the grinding wheel head is adjusted by remote control or mechanical operation to complete the tool setting. After the tool setting is completed, the hydraulic system is operated to clamp the grinding mechanism so that the rail bottom slope angle cannot change. At this time, the tool setting is completed and the system memorizes the coordinate value.

[0062] (4) Confirm the tool position in the axial direction (X direction), lateral direction (Y direction), and vertical direction (Z direction), and operate the grinding head to restore and lift it to the origin; lift the grinding wheel upward in the Z direction by a distance H, move it backward in the X direction by a distance a, and then descend to the tool coordinates (Z value, X value, Y value).

[0063] (5) Start the grinding No. 1 main motor. The motors are started in sequence. After the first motor starts and runs smoothly, the second main motor No. 2 is started. After a period of time (the two motors can also be started at the same time), the two grinding motors can be controlled to start and stop independently, and the grinding amount can be controlled independently;

[0064] (6) After the grinding wheel 1 rotates at high speed, it moves to the tool setting position and starts the grinding operation. It automatically grinds the rail support platform No. 1 according to the cutting amount d1. The grinding of the rail support platform No. 1 is completed according to N = D / d times, that is, the grinding of the rail support platform of the first pair of sleepers 5; the grinding path is the grinding path 2 of the first pair of sleepers; after the last grinding, you can choose whether to repeat the grinding of the previous track to improve the grinding quality.

[0065] (7) After the grinding of the rail support of sleeper No. 1 is completed, the grinding wheel 1 moves quickly for a distance b without cutting, reaches the grinding position of rail support No. 2, and automatically grinds the rail support of sleeper No. 2 according to the cutting amount d1. The grinding of rail support No. 2 is completed according to N = D / d times, that is, the grinding of the rail support of the second pair of sleepers 6; the grinding path is the grinding path 3 of the second pair of sleepers; after the last grinding, you can choose whether to repeat the grinding of the previous track to improve the grinding quality.

[0066] (8) The grinding wheel 1 quickly moves a distance b to reach the grinding position of the No. 3 rail support platform, and automatically grinds the No. 3 rail support platform according to the cutting amount d1. The grinding of No. 3 rail support platform is completed according to N = D / d times, that is, the grinding of the rail support platforms of the third pair of sleepers 7; the grinding path is the third pair of sleepers grinding path 4. After the last grinding, you can choose whether to repeat the grinding of the previous track to improve the grinding quality.

[0067] (9) After grinding three or more pairs of rail bearing platforms in sequence, the grinding head returns to the starting point;

[0068] (10) The grinding device moves to the next operating position and prepares to start the cycle operation.

[0069] It is worth noting that the grinding device of the present application and the guiding and clamping devices in the grinding device can be realized by using the existing technology, and the specific structure of the grinding device is not the focus and innovation point of the application, so it will not be elaborated.

[0070] Based on the above, the technical solution provided by the present application can realize the complex working conditions with different grinding requirements for adjacent sleepers encountered during the grinding construction of the ballastless track support platform, improve the grinding efficiency, and realize the automation of the entire operation process; at the same time, the present application can save the time consumed in the operation of the sleeper spacing, and utilize the limited time on the grinding operation of the support platform, thereby improving the construction efficiency.

[0071] It is worth noting that the present application is applicable to the grinding of rail supports for single, double, triple and more sleepers. It is possible to realize the automatic control of the grinding amount of each rail support covering 3 or more sleepers, input the specific grinding amount of each rail support before grinding, and automatically complete the grinding operation of 6 or more rail supports with different grinding amounts, thus realizing the automatic grinding of multiple sleepers with different grinding amount requirements on site, meeting complex and personalized needs, and improving the grinding efficiency of rail supports. By adopting this grinding control method, the idle knife travel time of the sleeper spacing can be effectively shortened, the grinding efficiency can be improved, and the automatic control of the grinding process can be realized.
