Description

Technical Field

[0001] This utility model relates to a traction adjustment device, specifically a traction adjustment device for laying ballastless track, and belongs to the field of track inspection technology. Background Technology

[0002] A railway is a track for trains and other vehicles to travel on. Railway transportation is a mode of land transport in which locomotives pull trains along two parallel rails. Traditionally, it uses steel wheels, but in a broader sense, railway transportation also includes non-steel wheeled modes such as maglev trains, cable cars, and ropeways, which are also known as rail transport.

[0003] Existing equipment often leaves dust residue on the track during construction when inspecting it, which can obscure the QR code scanning area and make it difficult to clean. Scanning failures can prevent the measurement computer from obtaining complete track error data, resulting in incomplete fine-tuning files and requiring repeated measurements, thus slowing down the construction progress. To address these issues, we have developed a traction adjustment device for ballastless track laying. Utility Model Content

By measuring the round-trip time or angle change of the light wave, the precise distance and azimuth between the prism 14 and the instrument can be calculated.

[0027] Please see Figure 5 A fixing rod 10 is fixedly connected to the upper surface of the track inspection vehicle 9. A connecting block 8 can be fixed by a fastening shaft 7. The connecting block 8 is installed on the track inspection vehicle 9, thereby fixing the track inspection vehicle 9 being pulled.

The fixing rod 10 is installed on the track inspection vehicle 9. The second connecting rod 11 and the QR code scanner 12 can be fixed by the fixing rod 10. The second connecting rod 11 can be adjusted on the fixing rod 10, and the scanning position of the QR code scanner 12 can be adjusted according to the position of the track.

[0028] Please see Figure 1 and Figure 2 A control device 3, a display screen 4, and an alarm device 5 are all fixedly connected to the upper surface of the tractor 1. The control device 3, display screen 4, and alarm device 5 are all installed on the tractor 1. The control device 3 can control the movement of the tractor 1, the display screen 4 can observe the working status of the tractor 1, and the alarm device 5 can warn the staff, making it convenient for the staff to control the tractor 1 to stop and start in time. A cleaning mechanism 2 is set on one side of the tractor 1. The cleaning mechanism 2 includes a fixed plate 201 fixedly connected to one side of the tractor 1. A fixed shell 202 is fixedly connected to the upper surface of the fixed plate 201. The inner wall of the fixed shell 202 is rotatably connected to the outer surface of the rotating column 206. The output shaft of the first motor 203 is rotatably connected to the inner wall of the fixed shell 202. The rotating column 206 is installed on the fixed shell 202 to prevent the rotating column 206 from shaking when rotating, thus playing a fixing role. The first motor 203 is installed on the fixed shell 202 to prevent the first motor 203 from shaking when working, thus playing a fixing role.

[0029] Please see Figure 3 A first motor 203 is fixedly connected to one side of the fixed housing 202. A first helical gear 204 is fixedly connected to the output shaft of the first motor 203. The first helical gear 204 meshes with a second helical gear 205. A rotating column 206 is fixedly connected to the middle of the second helical gear 205. A threaded rod 207 is threadedly connected to the inner wall of the rotating column 206. A cleaning plate 208 is fixedly connected to one end of the threaded rod 207. A guide rod 209 is fixedly connected to one side of the cleaning plate 208. The outer surface of the guide rod 209 is slidably connected to the inner wall of the fixed housing 202. When inspecting the track, the position with the QR code needs to be cleaned to prevent the QR code scanner 12 from failing to scan during inspection. When the tractor 1 moves on the track, the position with the QR code can be cleaned by the cleaning plate 208. A data transmission module, a signal receiver, a brushless motor, and a network connection module are provided inside the tractor 1. The data transmission module, signal receiver, brushless motor, and network connection module are all controlled by wire connections.

[0030] The first motor 203, control device 3, display screen 4, alarm device 5, QR code scanner 12, data transmission module, signal receiver, brushless motor and network connection module in this application are all common electrical devices in the prior art, and their models or specific structures will not be described in detail in this application.

[0031] Working principle: The operator starts the system through the control device 3 above the tractor 1. The tractor 1 moves slowly along the track. The tractor 1 pulls the track inspection vehicle 9 behind it synchronously through the first connecting rod 6 and the fastening shaft 7, ensuring that the two remain stably connected. When the tractor 1 moves, the first motor 203 starts, driving the first helical gear 204 on the output shaft to rotate. The first helical gear 204 meshes with the second helical gear 205, transmitting power to the rotating column 206. The threads on the inner wall of the rotating column 206 drive the threaded rod 207 to move linearly, pushing the cleaning plate 208 to slide back and forth along the guide rod 209, removing dust and debris from the track surface, especially the QR code area. The QR code scanner 12 on the track inspection vehicle 9 is connected through the second connecting rod 6 and the fastening shaft 7. The height of rod 11 is adjusted by sliding within the fixed rod 10. It is aligned with the QR code mark on the track. The QR code scanner 12 recognizes the QR code, obtains the track panel number and preset coordinates, and other construction parameters. The data is then fed back to the display screen 4 via the data transmission module. If the scan fails, the alarm device 5 is triggered. The prism 14 on the top of the track inspection vehicle 9 serves as an optical target, reflecting the laser signal emitted by the total station. The total station calculates the three-dimensional coordinates of the track based on the reflected signal from the prism 14. The measurement results are fused with the data from the QR code scanner 12 to generate a track fine-tuning file to guide subsequent construction. If the track deviation exceeds the standard or the QR code cannot be recognized, the alarm device 5 issues a warning, the traction vehicle 1 is paused, and the operation resumes after manual intervention, thus cleaning the scanned area.
