Description

Technical Field

[0001] The invention belongs to the technical field of track crack detection devices, in particular to a railway ballastless track crack detection device. Background Art

[0002] Ballastless track, also known as ballastless track, refers to a track structure that uses a monolithic foundation of concrete or asphalt mixtures instead of a granular gravel roadbed. It is currently the world's most advanced track technology. Compared to ballasted track, ballastless track avoids ballast splashing, offers improved smoothness, stability, long service life, durability, and minimal maintenance, allowing trains to operate at speeds exceeding 350 km / h. However, cracks can develop on track over time, necessitating detection and repair.

[0003] In the Chinese patent publication number CN116061987A, a railway ballastless track crack detection device is mentioned. The invention uses a walking mechanism to drive a supporting mechanism to move, and the supporting mechanism drives a cleaning mechanism to move, so that the first cleaning plate and the second cleaning plate in the cleaning mechanism clean the top and sides of the track. Then, the impurities swept out by the first cleaning plate and the second cleaning plate on the track are cleaned by the air blast cleaning mechanism, so that the track surface is free of dust and garbage, so that the detection mechanism can detect track cracks more accurately and improve the accuracy of detection.

[0004] However, this invention uses a cleaning mechanism to clean the track, making it easier for the detection mechanism to detect and photograph the track for cracks, but does not mark the track cracks. When subsequent staff need to repair the cracks, they need to search for and check for the cracks on the track, which increases the workload and labor of the staff, wastes working time, and is prone to missing cracks during crack detection. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention starts the telescopic cylinder by controlling the server to push the lifting plate to slide downward inside the fixed groove, thereby pushing the marking sponge to slide downward. The marking sponge absorbs a marking liquid with a striking color. The marking sponge moves downward to the track body and presses the marking liquid onto the upper surface of the track body to mark the cracks on the track body, making it convenient for staff to find the cracks on the track body and repair them later.

[0029] Embodiment 1: The present invention provides a railway ballastless track crack detection device, including a power supply mechanism 200, the power supply mechanism 200 includes a fixing frame 201 fixedly mounted on the upper surface of a support plate 107, a solar panel 202 is fixedly mounted on the outer surface of the fixing frame 201, and a distribution box 203 is fixedly mounted on the upper surface of the support plate 107.

[0030] A control server 204 is fixedly mounted on the upper surface of the support plate 107 , and a debugging button 205 and a display screen 206 are provided on the front side of the control server 204 .

[0031] As can be seen from the above, solar energy is absorbed by the solar panel 202 and converted into electrical energy, which is stored in the distribution box 203 to provide power for the overall circuit of the track crack detection device. The control server 204 is the control center of the device, which facilitates the control of the device and data storage.

[0032] Embodiment 2: This is the second embodiment of the present invention, which includes a moving mechanism 100. The moving mechanism 100 includes two track bodies 101. A bracket 106 is provided above the track body 101. A support plate 107 is fixedly installed on the upper surface of the bracket 106. The moving mechanism 100 also includes a number of support frames 103 fixedly installed on the lower surface of the bracket 106. A number of driven wheels 102 are fixedly installed on the outer surfaces of the support frames 103. The driven wheels 102 are slidably connected to the track. The support frames 103 are internally rotatably connected to the driving wheels 104. The driving wheels 104 are slidably connected to the track body 101. A driving assembly 105 is fixedly provided on one side of the support frame 103. The output end of the driving assembly 105 passes through the support frame 103 and is fixedly connected to the driving wheel 104.

[0033] As can be seen from the above, by controlling the server 204 to start the driving component 105, the active wheel 104 is driven to slide on the upper surface of the track body 101, thereby driving the support frame 103 and the driven wheel 102 to move, and then driving the bracket 106 and the support plate 107 to move, so that the track crack detection device can move slowly on the track body 101, making it convenient to detect track cracks.

[0034] Embodiment 3: This is the third embodiment of the present invention, which includes a cleaning mechanism 300. The cleaning mechanism 300 includes two support columns 301 fixedly installed on the lower surface of the front end of the support plate 107. The lower ends of the two support columns 301 are fixedly installed with scraper grooves 302. The scraper grooves 302 slide in conjunction with the track body 101. The cleaning mechanism 300 also includes a vacuum cleaner 303 fixedly installed on the lower surface of the support plate 107. Dust pipes 304 are connected on both sides of the vacuum cleaner 303. The vacuum cleaner 303 is connected to a recycling box 305. The recycling box 305 is installed on the upper surface of the support plate 107.

[0035] As can be seen from the above, the detection device is driven to move forward as a whole by the moving mechanism 100, thereby pushing the scraper groove 302 to slide on the outer surface of the track body 101. The scraper groove 302 has a certain hardness and can clean up the garbage stuck on the outer surface of the track together, so that the garbage on the outer surface of the track can be cleaned up, which is convenient for detecting and photographing cracks. At the same time, the vacuum cleaner 303 is started, and the garbage is sucked into the recycling box 305 through the vacuum tube 304, which can prevent the garbage from accumulating directly on both sides of the track.

[0036] Embodiment 4: This is the fourth embodiment of the present invention, comprising a detection mechanism 400 , which comprises two connecting columns 401 relatively fixedly mounted on the lower surface of the support plate 107 , with balls 402 fixedly mounted on the lower surfaces of the two connecting columns 401 .

[0037] A crack detector 403 is fixedly mounted on the lower surface of the connecting column 401 , and two shooting assemblies 404 are relatively fixedly mounted on the lower surface of the supporting plate 107 .

[0038] As can be seen from the above, the ball 402 moves on the track driven by the moving mechanism 100, thereby moving the crack detector 403 to detect cracks on the track body 101. When a crack is detected, the signal is transmitted to the control server 204. The control server 204 controls the shooting component 404 to shoot the crack and store it in the storage unit of the control server 204 for the convenience of staff to view.

[0039] Embodiment 5: This is the fifth embodiment of the present invention. The marking mechanism 500 includes a telescopic cylinder 501 fixedly installed on both sides of the support plate 107. Fixed grooves 502 are fixedly installed on both sides of the support plate 107. The two telescopic cylinders 501 are respectively installed on the upper surfaces of the two fixed grooves 502. The output end of the telescopic cylinder 501 passes through the fixed groove 502, and a lifting plate 503 is fixedly connected to the end of the end. A fixing ring 504 is fixedly connected to one side of the lifting plate 503, and a marking sponge 505 is fixedly installed inside the fixing ring 504. The cleaning mechanism 300 includes two support columns 301 fixedly installed on the lower surface of the front end of the support plate 107. The lower ends of the two support columns 301 are fixedly installed with scraper grooves 302, and the scraper grooves 302 slide in conjunction with the track body 101.

[0040] The marking mechanism 500 further includes a moisture detector 506 fixedly connected to one side of the lifting plate 503 , and the moisture detector 506 is connected to the marking sponge 505 .

[0041] A marking box 507 is fixedly installed on the upper surface of the support plate 107, and discharge pipes 508 are fixedly connected on both sides of the marking box 507. One end of the discharge pipe 508 is connected to a material pump 509, and the material pump 509 is fixedly connected to the support plate 107. The discharge end of the material pump 509 is connected to a feeding pipe 510, and the discharge end of the feeding pipe 510 is movable through the support plate 107, and this end is fixedly connected to the marking sponge 505.

[0042] As can be seen from the above, the control server 204 starts the telescopic cylinder 501, pushing the lifting plate 503 to slide downward inside the fixed groove 502, thereby pushing the marking sponge 505 to slide downward. The marking sponge 505 absorbs a marking liquid with a striking color. The marking sponge 505 moves downward to the track body 101, presses the marking liquid onto the upper surface of the track body 101, and marks the cracks in the track body 101, making it convenient for the staff to find the cracks in the track body 101 and repair the cracks later.

[0043] When the moisture detector 506 detects that the moisture in the marking sponge 505 is less than the set value, the signal is transmitted to the control server 204. The control server 204 starts the material pump 509, draws out the marking liquid inside the marking box 507, and enters the marking sponge 505 through the feeding pipe 510 to replenish the marking liquid to the marking sponge 505.

[0044] The working principle of the present invention is as follows: the driving component 105 is started by the control server 204, driving the active wheel 104 to slide on the upper surface of the track body 101, thereby driving the support frame 103 and the driven wheel 102 to move, and then driving the bracket 106 and the support plate 107 to move, so that the track crack detection device can move slowly on the track body 101, and the detection device is driven to move forward as a whole by the moving mechanism 100, thereby pushing the scraper groove 302 to slide on the outer surface of the track body 101. The scraper groove 302 has a certain hardness and can clean up the garbage stuck on the outer surface of the track together, so that the garbage on the outer surface of the track can be cleaned up. At the same time, the vacuum cleaner 303 is started and the garbage is sucked into the recycling box 3 through the vacuum pipe 304. 05. The ball 402 moves on the track driven by the moving mechanism 100, thereby moving the crack detector 403 to detect cracks on the track body 101. When a crack is detected, the signal is transmitted to the control server 204. The control server 204 controls the shooting component 404 to shoot the crack and stores it in the storage unit of the control server 204. The control server 204 starts the telescopic cylinder 501 to push the lifting plate 503 to slide downward inside the fixed groove 502, thereby pushing the marking sponge 505 to slide downward. The marking sponge 505 absorbs a marking liquid with a striking color. The marking sponge 505 moves downward to the track body 101, presses the marking liquid onto the upper surface of the track body 101, and marks the cracks on the track body 101.

[0045] When the moisture detector 506 detects that the moisture in the marking sponge 505 is less than the set value, the signal is transmitted to the control server 204. The control server 204 starts the material pump 509, draws out the marking liquid inside the marking box 507, and enters the marking sponge 505 through the feeding pipe 510 to replenish the marking liquid to the marking sponge 505.
