[0026] The present invention is further described in detail below through the accompanying drawings and specific implementation methods.
[0027] Example
[0028] Please refer to Figure 1 The present embodiment provides a track centerline calibration device, comprising a guide rail 1, a centering block 2, a centering distance sensor 3, a marking rod 4 and a storage bin 5, wherein the guide rail 1 is provided with a telescopic portion 110; rollers 120 are rotatably mounted at both ends of the guide rail 1, and pressure sensors are respectively mounted on the rollers 120; walking wheels 130 are rotatably mounted on both sides of the bottom of the guide rail 1; the centering block 2 is arranged at the middle position of the guide rail 1; two centering distance sensors 3 are provided, which are respectively mounted at both ends of the guide rail 1, and are respectively used to measure the distance between the two ends of the guide rail 1 and the middle position of the centering block 2; the top end of the marking rod 4 is connected to the middle position of the centering block 2; the storage bin 5 is arranged at the bottom end of the marking rod 4; and a discharge port is opened at the bottom end of the storage bin 5.
[0029] Please refer to Figure 2When laying the rails 710 on the top surfaces of the two side walls of the inspection pit 720, h represents the track construction range, that is, the construction height range of the rails on the tops of the two side walls of the inspection pit 720. The length direction of the rails 710 is the same as the length direction of the inspection pit 720. For example, the middle position of the width of the inspection pit 720 is set as the line centerline 723, that is, the centerline of the track; the centerline between the rails 710 on both sides must coincide with the line centerline 723. The track centerline calibration device of this embodiment can be used after the inspection pit 720 is completed and before the rails 710 are laid, and can be mainly used for track adjustment related work such as rough laying, fine adjustment, and review after fine adjustment of the rails 710.
[0030] Please refer to Figures 3 to 5 The track centerline calibration device of this embodiment, when used, may include the following steps:
[0031] Place the calibration device: move the track centerline calibration device into the inspection pit 720 and place it stably; arrange the guide rail 1 along the width direction of the inspection pit 720, and the running wheel 130 can drive the track centerline calibration device to move along the length direction of the inspection pit 720.
[0032] Among them, a drainage ditch 721 and an inspection pit surface 722 can be set in the inspection pit 720. The drainage ditch 721 is opened in the middle position of the bottom surface of the inspection pit 720, and the inspection pit surfaces 722 are respectively set on both sides of the drainage ditch 721; at this time, the walking wheels 140 on both sides of the track centerline calibration device can be placed on the inspection pit surfaces 722 on both sides respectively.
[0033] Adjust the guide rail: adjust the length of the guide rail 1 by extending and retracting the telescopic part 110 to adapt to the width of the inspection pit 720; sense the pressure value through the pressure sensors on the rollers 120 at both ends, determine that the rollers 120 at both ends are in contact with the inner walls of the inspection pit 720 and stop the extension and retraction of the telescopic part 110.
[0034] Confirm the centering block: Use two centering distance sensors 3 to confirm that the middle position of the centering block 2 is equal to the distance between the two ends of the guide rail 1.
[0035] Calibrate the track centerline: close the discharge port and add marking material into the storage bin 5; drive the track centerline calibration device to move along the length direction of the inspection pit 720 through the walking wheel 130, and at the same time, the rollers 120 on both sides roll on the inner walls on both sides of the inspection pit 720 to ensure that the track centerline calibration device moves stably in the inspection pit 720; at the same time, open the discharge port to allow the marking material to flow out, and form a marking line as the track centerline calibration device moves forward, thereby realizing the track centerline calibration.
[0036] like Figure 1As shown, the telescopic portion 110 can be configured as a telescopic rod, so as to adjust the length of the guide rail 1 by extending and retracting the telescopic rod.
[0037] The centering block 2 can be movably arranged on the guide rail 1, so as to facilitate the movement and adjustment of the position of the centering block 2 on the guide rail 1, so that the centering block 2 is located in the middle position of the guide rail 1 and in the center line position of the track. At this time, the telescopic part 110 can be provided as one and arranged at one end of the guide rail 1, so as to facilitate the length adjustment of the guide rail 1 through the telescopic part 110 at one end.
[0038] The telescopic parts 110 may also be provided in two numbers and respectively provided at the two ends of the guide rail 1, so that the length of the guide rail 1 can be adjusted by telescoping the telescopic parts 110 at the two ends. In this case, the centering block 2 may be fixedly provided in the middle of the guide rail 1, and the length of the telescopic parts 110 at the two ends of the guide rail 1 may be symmetrically extended and retracted, so that the centering block 2 may be kept in the middle of the guide rail and in the centerline of the rail.
[0039] The centering distance sensor 3 may be provided with a first signal emitting unit and a first signal reflecting unit, wherein the first signal emitting unit is installed at the end of the guide rail 1, and the first signal reflecting unit is installed at the middle position of the centering block 2; or, the first signal reflecting unit is installed at the end of the guide rail 1, and the first signal emitting unit is installed at the middle position of the centering block 2; thereby realizing measuring the distance between the two ends of the guide rail 1 and the middle position of the centering block 2 respectively through the two centering distance sensors 3.
[0040] A travel distance sensor 6 may be installed on the guide rail 1. The travel distance sensor 6 is provided with a second signal transmitting unit. The signal transmitting direction of the second signal transmitting unit is the same as the travel direction of the running wheel 130. The travel distance sensor 6 can monitor the distance between the track centerline calibration device and the obstacle in the travel direction, so that when an obstacle is detected in the travel direction, the track centerline calibration device can be stopped in time to prevent the track centerline calibration device from colliding with the obstacle during travel. For example, the obstacle can be the end wall of the inspection pit 720.
[0041] The marking rod 4 can be set as a telescopic rod, so that the length of the marking rod 4 can be adjusted according to actual conditions, thereby adjusting the height position of the storage bin 5 and the discharge port.
[0042] The centering block 2 can be installed on the bracket 140. Two legs are respectively arranged on both sides of the bottom of the bracket 140. The four legs are distributed in a rectangular shape. The bottom ends of the legs are rotatably installed with running wheels 130, which is convenient for the installation of the guide rail 1 and the running wheels 130. The four running wheels 130 also facilitate the balanced and stable movement of the calibration device.
[0043] In the track centerline calibration device of this embodiment, the guide rail 1 can be set as a horizontal crossbar. The telescopic portion 110 can be set as a horizontal transverse telescopic rod of the same shape as the guide rail 1, such as a round telescopic rod or a square telescopic rod. The central axis of the roller 120 is set to be vertical. The central axis of the running wheel 130 is set to be horizontal and transverse, and the running wheel 130 can be set to be a universal wheel.
[0044] The universal wheel can adopt an existing technical product with directional rotation in two directions perpendicular to each other, so that it can drive the guide rail 1 to move only in the forward direction or only in the lateral direction. Therefore, the rotation direction of the universal wheel can be adjusted to the forward direction as needed to drive the guide rail 1 forward; or, the rotation direction of the universal wheel can be adjusted to the lateral direction to drive the guide rail 1 to move left and right, which is conducive to adjusting the pressure sensing values of the pressure sensors on both sides of the guide rail 1 to be the same.

[0049] Both ends of the guide rail 1 are provided with telescopic parts 110, and the centering block 2 is sleeved and fixedly connected to the middle position of the guide rail 1. At this time, if there is an error in the synchronous telescopic extension of the telescopic parts 110 at both ends of the guide rail 1, resulting in different values of the pressure sensors at both ends of the guide rail 1 after telescopic adjustment, the rotation direction of the universal wheel can be adjusted to the horizontal direction, and the guide rail 1 can be driven to move horizontally, so that the values of the pressure sensors at both ends of the guide rail 1 are adjusted to be the same; then, the rotation direction of the universal wheel is adjusted to the forward direction, and the guide rail 1 is driven to move forward along the length direction of the inspection pit 720.
