[0017] In the absence of conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other.
[0018] In order to make the technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] Figure 1 An exemplary system architecture 100 is shown to which an embodiment of a track starting method or a track starting device of the present disclosure can be applied.
[0020] like Figure 1 As shown, the system architecture 100 may include a target rail 101 , a track-lifting unit 102 placed on the target rail 101 , and a control device 103 .
[0021] The track-lifting machine group 102 may include a plurality of track-lifting machines, and each track-lifting machine may work in conjunction, that is, each track-lifting machine may be spaced apart by a target working distance to perform track-lifting operations on the rails, so that railway maintenance personnel may fine-tune target rails of a longer distance at the same time. Of course, each track-lifting machine in the track-lifting machine group may also work independently.
[0022] The control device 103 can interact with each track-lifting machine in the track-lifting machine group 102 to send a control instruction to each track-lifting machine in the track-lifting machine group 102. The control device can be set in a track-lifting machine in the track-lifting machine group 102, or in an electronic device outside the track-lifting machine group 102.
[0023] The execution subject of the track raising method in the present disclosure may be the control device 103. In addition, the track raising device is arranged on each track raising machine in the track raising machine group 102.
[0024] It should be understood that Figure 1 The number of track-lifting machines in the embodiment is only for illustration. According to the implementation requirements, any number of track-lifting machines can be provided.
[0025] Figure 2 FIG. 2 shows a process 200 of an embodiment of a track raising method disclosed in the present invention. The track raising method of the present embodiment is applied to a track raising unit, and the track raising unit includes at least two track raising machines. Figure 2 As shown, the track starting method of this embodiment may include the following steps:
[0026] Step 201, obtaining the measured rail temperature of the target rail.
[0027] In this embodiment, the measured rail temperature of the target rail can be obtained in various ways. For example, a temperature sensor can be provided on the target rail, and the measured rail temperature of the target rail can be obtained by interacting with the temperature sensor. Alternatively, a temperature sensor can be provided on a part of the track lifter that contacts the target rail, and when the track lifter contacts the target rail, the measured rail temperature of the target rail can be obtained through the temperature sensor.
[0028] Step 202, determining the operating rail temperature according to the measured rail temperature and the designed rail temperature of the target rail.
[0029] After obtaining the measured rail temperature of the target rail, the designed rail temperature of the target rail can also be obtained. Here, the designed rail temperature can be obtained through the design data of the target rail, which is set according to the environment in which the target rail is located, the material of the target rail, and other information. The measured rail temperature can be subtracted from the above-mentioned designed rail temperature to obtain the operating rail temperature.
[0030] Step 203, based on the operating rail temperature and the preset corresponding relationship between the operating rail temperature and the working distance, determine the target working distance between two adjacent track-lifting machines in the track-lifting machine group.
[0031] After obtaining the operating rail temperature, the target working distance between two adjacent track-lifting machines in the track-lifting unit can be determined based on the operating rail temperature and the preset correspondence between the operating rail temperature and the working distance. Specifically, the above preset correspondence can be predetermined by a technician based on the mapping relationship between the operating rail temperature and the working distance. The working distance corresponding to the operating rail temperature can be used as the target working distance. Alternatively, the target working distance can be further determined in combination with other information. Alternatively, it can be first determined based on the rail temperature whether the target rail needs to be cooled or other treatments. If not, the preset value is used as the target working distance.
[0032] Step 204, determining the target initial distance between two adjacent track-lifting machines.
[0033] In this embodiment, the target initial distance between two adjacent track-lifting machines can also be determined. The target initial distance here is the distance between two adjacent track-lifting machines before each track-lifting machine works separately. It can be understood that if the target initial distance is small, it will not be conducive to the adjustment and control of the track-lifting machine. If the target initial distance is large, it will not be conducive to the linkage control of each track-lifting machine. Therefore, it is necessary to set a suitable target initial distance. In this embodiment, the target initial distance can be set according to the effective detection distance of the distance sensor on the track-lifting machine and / or the working distance corresponding to the operating track temperature. Specifically, the smaller value of the two can be used as the target initial distance. Or the target initial distance can be determined based on the space required for the adjustment and control operation of the track-lifting machine, combined with the effective detection distance of the distance sensor. Specifically, the smaller value of the required space and the effective detection distance can be used as the target initial distance.
[0034] Step 205, controlling each track-lifting machine in the track-lifting machine group to perform track-lifting operation on the target rail according to the target working distance and the target initial distance.
[0035] After determining the target working distance and the target initial distance, each track-lifting machine in the track-lifting machine group can be controlled to perform track-lifting operations on the target rail. Specifically, before the track-lifting operation, the distance between two adjacent track-lifting machines in the track-lifting machine group can be adjusted to the target initial distance. Then, during the operation, the distance between the two adjacent track-lifting machines is kept no greater than the target working distance. Track-lifting operation refers to the operation of fixing the rail head through the clamping device in the track-lifting machine, driving the hydraulic push rod to move downward, and raising the target rail to a preset height.
[0036] The track lifting method provided by the above-mentioned embodiment of the present disclosure can determine the target working distance between each track lifting machine in the track lifting machine group according to the operating rail temperature, and can control each track lifting machine to perform track lifting operations on the target rail in combination with the target initial distance, thereby improving the efficiency of track lifting.
[0037] Continue to see Figure 3 , which shows a process 300 of another embodiment of the track starting method according to the present disclosure. Figure 3 As shown, the method in this embodiment may include the following steps:
[0038] Step 301, initializing the settings of each track-lifting machine in the track-lifting machine group, and obtaining the initialization setting data of each track-lifting machine; in response to determining that the initialization setting data of each track-lifting machine are the same, obtaining the measured rail temperature of the target rail.
[0039] In this embodiment, before performing the track-lifting operation, each track-lifting machine in the track-lifting machine group needs to be initialized. Specifically, an initialization instruction can be sent to each track-lifting machine, and each track-lifting machine can perform initialization settings after receiving the initialization instruction. After performing the initialization settings, initialization setting data can be generated. The initialization setting data of each track-lifting machine can be compared, and if they are the same, it is considered that the initialization of each track-lifting machine is completed, and subsequent track-lifting operations can be performed. In this case, the measured rail temperature of the target rail can be obtained.
[0040] The initialization setting data may include the detection zero position of the track-starting machine, the state of the track-starting machine, etc. In some specific practices, the track-starting machine group may include two track-starting machines, which are respectively recorded as the linkage track-starting machine and the driven track-starting machine. The linkage track-starting machine can be understood as the track-starting machine that moves first among the two track-starting machines, and the driven track-starting machine can be understood as the track-starting machine that moves later among the two track-starting machines. The specific initialization setting data can be found in the following table.
[0041] Linked track lifting machine Driven track lift Start delay(s) 0.00 0.00 Falling delay(s) 2.00 2.00 Detection protection(s) 1.00 1.00 Detection delay(s) 0.00 0.00 Parking time(s) 0.50 0.50 Rise time(s) 2.00 2.00 Detection digits (bits) 0 0
[0042] The parameter values in the above initialization data can be determined based on actual experience or based on the hardware of the track lifting machine.
[0043] Step 302, determining the curvature radius of the target rail; and determining the target working distance according to the curvature radius, the operating rail temperature and a preset corresponding relationship.
[0044] In this embodiment, the curvature radius of the target rail can also be determined. Specifically, the curvature radius and the actual locked rail temperature can be obtained by querying the laying information of the target rail. After the curvature radius is obtained, the target working distance can be determined according to the curvature radius, the operating rail temperature and the preset corresponding relationship.
[0045] In some specific practices, it is also possible to further consider whether the target rail is paved with ballast to determine the target working distance. Specifically, the target working distance can be determined by the following table.
[0046]
[0047] Step 303, determining the target initial distance between each track-lifting machine according to the distance sensor installed on each track-lifting machine.
[0048] In this embodiment, each track lifter is equipped with a distance sensor. The distance sensor may be an infrared distance sensor, a laser distance sensor, etc. The effective detection distance of the distance sensor may be combined with the working distance corresponding to the operating track temperature. The effective detection distance may be obtained by repeated measurements by technicians.
[0049] Step 304, within a single operation cycle, the distance between two adjacent track-lifting machines in the track-lifting unit is controlled to be adjusted to the target working distance; in response to the distance adjustment being complete, each track-lifting machine in the track-lifting unit is controlled to perform a track-lifting operation on the target rail; in response to receiving a fine-tuning completion instruction, the distance between two adjacent track-lifting machines in the track-lifting unit is controlled to be adjusted to the target initial distance.
[0050] In this embodiment, the fine-tuning operation of the target rail can be divided into multiple operation cycles. In a single operation cycle, the distance between two adjacent track-lifting machines in the track-lifting machine group can be first controlled to be the target working distance. Specifically, the position of each track-lifting machine in the track-lifting machine group can be adjusted with a certain position as the starting point, so that the distance between two adjacent track-lifting machines is finally the target working distance. Alternatively, a center point is fixed, a track-lifting machine is fixed at the center point, and then the positions of other track-lifting machines are moved so that the distance between two adjacent track-lifting machines is the target working distance.
[0051] After the distance adjustment is completed, each track-lifting machine in the track-lifting machine group can be controlled to perform track-lifting operation on the target rail. Specifically, the target rail can be raised to a preset height. It is understandable that the preset height here can be a height suitable for technicians to perform operations such as replacing gaskets on the target rail.
[0052] After the technician has completed fine-tuning the target rail, he can input a fine-tuning completion command. If the track-lifting machine or the controller receives the fine-tuning completion command, the distance between two adjacent track-lifting machines in the track-lifting machine group can be controlled to be the target initial distance. In this way, the fine-tuning of the target rail can be achieved in a single cycle, and the control of each track-lifting machine in the track-lifting machine group can also be achieved.
[0053] In some optional implementations of the present embodiment, within a single operation cycle, the position of the last track-lifting machine in the track-lifting machine group can be first fixed, and each track-lifting machine before the last track-lifting machine can be controlled to move forward so that the distance between two adjacent track-lifting machines is the target working distance.
[0054] In this implementation, the position of the last track-lifting machine in the track-lifting machine group can be fixed first. Then, each track-lifting machine before the last track-lifting machine is controlled to move forward and stop when the distance between two adjacent track-lifting machines reaches the target working distance. Then, each track-lifting machine can perform the track-lifting operation.
[0055] In some optional implementations of the present embodiment, after receiving the fine-tuning completion command, the position of the first track-lifting machine in the track-lifting machine group can be fixed, and the track-lifting operation of the first track-lifting machine can be maintained, and each track-lifting machine after the first track-lifting machine can be controlled to stop the track-lifting operation and move forward, so that the distance between two adjacent track-lifting machines is the target initial distance.
[0056] In some optional implementations of the present embodiment, after controlling the distance between two adjacent track-lifting machines in the track-lifting machine group to be the target initial distance, the last track-lifting machine can also be controlled to perform track-lifting operations on the target rail, and the track-lifting machines before the last track-lifting machine can be controlled to stop track-lifting operations.
[0057] In some specific practices, the track-lifting group includes two track-lifting machines. The starting positions of the two track-lifting machines (represented by track-lifting machine 1 and track-lifting machine 2 below. Track-lifting machine 1 represents the linkage machine and is the first one in the direction of travel, and track-lifting machine 2 is the slave machine and is located after the linkage machine) are as follows: Figure 4a As shown in the figure, the initial distance between the two track-lifting machines is 30-50 cm. After the automatic operation starts, the track-lifting machine 1 moves forward by the set distance, i.e. the target working distance, and the track-lifting machine 2 stops at the same place, reaching the following Figure 4b At this time, both track-lifting machine 1 and track-lifting machine 2 make the hydraulic push rod work to raise the rail to a certain height (0-2cm). Here, the track-lifting height of the two track-lifting machines is based on 2cm as the standard, which is convenient for the subsequent replacement of fasteners such as gaskets.
[0058] After the fine adjustment between track-lifting machine 1 and track-lifting machine 2 is completed, press the start button on the remote control, track-lifting machine 2 raises its legs and puts down the rails, moves forward to the rear side of track-lifting machine 1, and maintains the target initial distance with track-lifting machine 1. Figure 4c As shown. After the track-lifting machine 2 stops, it drives the hydraulic push rod to lower the outriggers and replaces the track-lifting machine 1 to lift the track. At this time, the track-lifting machine 1 receives the sensor signal from the track-lifting machine 2, lifts the outriggers and moves forward a set distance, that is, the target working distance, to reach Figure 4d At this time, the distance between the track lifting machine 1 and the track lifting machine 2 is once again as Figure 4b The distance shown, further, track lifting machine 1 and track lifting machine 2 reciprocate according to the same process until all track lifting is completed.

At the same time, the present invention is also characterized by simple operation and easy control. It can improve the construction quality and reduce the difficulty of manual operation.
