[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A track maintenance inspection and flaw detection device includes a base plate 1, a hot air blower body 7 fixedly connected to the top of the base plate 1, flaw detection mechanisms 2 are provided on the front and rear sides of the left side of the base plate 1, a control module 6 is fixedly connected to the top of the base plate 1, a display screen 9 is provided on the top of the base plate 1, a blower mechanism 5 is provided on the front and rear sides of the right side of the base plate 1, and a scraping frame 14 is fixedly connected to the front and rear sides of the bottom of the base plate 1.

[0029] The blower mechanism 5 includes a fixed frame 501, a hollow frame 502, several exhaust nozzles 503 and three exhaust ports 504. The bottom of the fixed frame 501 is fixedly connected to the top of the hollow frame 502, the rear side of the hollow frame 502 is fixedly connected to the front side of the base plate 1, the side of the exhaust nozzle 503 near the hollow frame 502 is fixedly connected to the hollow frame 502, and the rear side of the exhaust port 504 is fixedly connected to the front side of the hollow frame 502. The exhaust port 504 is inclined.

[0030] In this embodiment: by contacting the anti-slip sleeves 21 of the four corner rollers 3 of the base plate 1 with the track, friction is increased. At this time, the wear-resistant soft rubber scraper frame 14 wraps around the track. The hot air blower body 7 is started, and hot air enters the hollow frame 502 through the double pipe 8 and is discharged from the exhaust nozzle 503 and the inclined exhaust port 504 to melt the ice and snow. The inclined design of the exhaust port 504 accelerates the melting and pushes the base plate 1 to move forward to the right. The scraper frame 14 can scrape off the water stains remaining on the track surface. The position of the flaw detector head 205 is adjusted by rotating the screw block 201. When working, it contacts the track for flaw detection. When not working, it can be moved into the protective sleeve 203 for protection. The number of flaw detections is... The data is wirelessly transmitted to the control module 6, and the results are analyzed and displayed on the screen 9. The baffle 17 blocks ice and snow to protect the flaw detection head 205. This device combines hot air snow melting and water scraping functions, which solves the problem proposed in the existing patent that the drive wheel can only be convenient to rotate in contact with the track surface when the track surface is dry. Especially when encountering icy and snowy weather during track maintenance, the drive wheel is prone to slippage, making it inconvenient to drive the fan to rotate through the pulley mechanism, thus affecting the rotation of the cleaning brush. Furthermore, the rotation of the cleaning brush is also difficult to completely remove the ice and debris attached to the track surface, affecting the accuracy of track flaw detection.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, the flaw detection mechanism 2 includes several screw blocks 201, fixing blocks 202, protective sleeves 203, threaded posts 204, and flaw detection heads 205. The right side of the fixing block 202 is fixedly connected to the left side of the base plate 1, the top of the protective sleeve 203 is fixedly connected to the bottom of the fixing block 202, the threaded post 204 is threadedly connected to the inside of the fixing block 202, the side of the screw block 201 near the threaded post 204 is fixedly connected to the threaded post 204, and the top of the flaw detection head 205 is fixedly connected to the bottom of the threaded post 204.

[0032] Specifically, such as Figure 1 and Figure 5 As shown, rollers 3 are provided at the four corners of the bottom of the base plate 1. A rotating shaft 19 is fixedly connected between the opposite sides of the front and rear rollers 3. A support block 20 is rotatably sleeved on the surface of the rotating shaft 19. There are two support blocks 20, and the top of the support block 20 is fixedly connected to the bottom of the base plate 1.

[0033] Specifically, such as Figure 1 and Figure 5 As shown, the surface of the roller 3 is fixedly fitted with an anti-slip sleeve 21.

[0034] In this embodiment: the threaded post 204 can be easily rotated by hand-held screw block 201. The threaded post 204 is connected to the inside of the fixed block 202 by threads. When the threaded post 204 is rotated, it can move up and down, thereby facilitating the up and down movement of the flaw detector head 205. The rotating shaft 19 and the support block 20 are movably connected, so the rotating shaft 19 and the roller 3 can be rotated at the same time, which facilitates the movement of the position of the base plate 1. The anti-slip sleeve 21 on the surface of the roller 3 contacts the track surface, which increases the friction and prevents the roller 3 from slipping.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, the output end of the hot air blower body 7 is fixedly connected to a double-pass pipe 8, and the side of the double-pass pipe 8 near the hollow frame 502 is fixedly connected to the hollow frame 502.

[0036] Specifically, such as Figure 1 and Figure 3 As shown, a bracket 22 is provided on the top of the scraping frame 14. The top of the bracket 22 is fixedly connected to the bottom of the base plate 1. A connecting frame 4 is fixedly connected to the surface of the scraping frame 14. An insert block 13 is fixedly connected to the top of the connecting frame 4. A slot 16 is provided inside the bracket 22. The insert block 13 is movably inserted into the slot 16. A pull ring 18 is fixedly connected to the surface of the connecting frame 4. The scraping frame 14 is made of wear-resistant soft rubber.

[0037] In this embodiment: the hot air generated when the hot air blower body 7 is working will be input into the hollow frame 502 through the double pipe 8, and then discharged through the exhaust nozzle 503 and exhaust port 504, blowing onto the track surface to melt the ice and snow on the track surface. The scraping frame 14 can scrape off the water stains left after the ice and snow melt, which is convenient for the subsequent flaw detection head 205 to detect flaws in the track. By inserting the plug 13 into the slot 16, the connecting frame 4 and the scraping frame 14 can be connected to the bracket 22.

[0038] Specifically, such as Figure 3 As shown, screws 15 are fixedly connected to the front and rear sides of the right side of the bracket 22. The bracket 22 has two threaded holes 12 inside. The left side of the screw 15 passes through the slot 16 and the insert 13 and is threadedly connected to the inside of the bracket 22.

[0039] Specifically, such as Figure 1 As shown, a support column 10 is fixedly connected to the top of the base plate 1, the bottom of the display screen 9 is fixedly connected to the top of the support column 10, a push rod 11 is fixedly connected to the top of the base plate 1, and baffles 17 are fixedly connected to the front and rear sides of the right side of the base plate 1.

[0040] In this embodiment: by removing screw 15, the insert 13 can be pulled out from inside slot 16 by holding pull ring 18, which facilitates the replacement of scraping frame 14. Support column 10 can stably support display screen 9 on top of base plate 1. By pushing push rod 11, roller 3 can be rotated, which facilitates the movement of base plate 1. Baffle 17 fixedly connected to the front and rear sides of right side of base plate 1 can prevent ice and snow from flying towards flaw detector head 205, thus avoiding ice and snow affecting the normal operation of flaw detector head 205.

[0041] Working principle: By pushing the push rod 11, the rollers 3 at the four corners of the bottom of the base plate 1 are used to move the base plate 1 until the anti-slip sleeve 21 on the surface of the roller 3 contacts the track surface. The anti-slip sleeve 21 increases the friction with the track, ensuring stability during movement. The rollers 3 are movably connected to the support block 20 through the rotating shaft 19, allowing the rollers 3 to rotate flexibly and adapt to changes in the track direction. When the base plate 1 reaches the designated position, the wear-resistant soft rubber scraping frame 14 contacts and wraps around the track. Then, the hot air blower body 7 is started. The hot air output by the hot air blower body 7 enters the hollow frame 502 through the double pipe 8. The exhaust nozzle 503 and the inclined exhaust port 504 on the hollow frame 502 discharge the hot air, melting the ice and snow on the track surface. The inclined design of the 4 allows the hot air to act more effectively on the track surface, accelerating the melting of ice and snow. Then, the push rod 11 is pushed, pushing the base plate 1 forward to the right. At this time, after the hot air melts the ice and snow, the scraping frame 14 further scrapes away the water stains on the track surface, creating good conditions for subsequent flaw detection work. The scraping frame 14 is movably inserted into the slot 16 of the bracket 22 through the insert block 13 on the connecting frame 4 and fixed by the screw 15, which facilitates installation and disassembly so that it can be replaced in time after wear. By rotating the screw block 201, the threaded column 204 is driven to rotate. Through the threaded connection between the threaded column 204 and the fixed block 202, the threaded column 204 can be moved up and down when it rotates, thereby adjusting the position of the flaw detection head 205. When it is necessary to align the track... When performing track flaw detection, the flaw detector head 205 is adjusted to a suitable height to contact the track. The right side of the fixing block 202 is fixed to the left side of the base plate 1, and the top of the protective sleeve 203 is connected to the bottom of the fixing block 202. When the flaw detector head 205 is not working, the threaded column 204 is rotated to move the flaw detector head 205 into the protective sleeve 203. The protective sleeve 203 can protect the flaw detector head 205 from accidental collisions. The data generated by the flaw detector head 205 during track flaw detection is transmitted to the control module 6 through mature wireless transmission technology. The control module 6 analyzes and processes the data and displays the flaw detection results in an intuitive form on the display screen 9. The display screen 9 is fixed to the top of the base plate 1 by the support column 10 for easy viewing by the operator. The right side of the base plate 1... The baffles 17, which are fixedly connected to the front and rear sides, can prevent ice and snow from flying towards the flaw detector head 205, thus avoiding the impact of ice and snow on the normal operation of the flaw detector head 205. The melting of ice and snow by hot air and the water scraping function of the scraping frame 14 ensure efficient and accurate completion of track flaw detection work under adverse weather conditions, ensuring the safe operation of the track. This solves the problem proposed in the existing patent that the drive wheel can only conveniently rotate in contact with the track surface when the track surface is dry. Especially when encountering icy and snowy weather during track maintenance, the drive wheel is prone to slippage, making it inconvenient to drive the fan to rotate through the pulley mechanism, thereby affecting the rotation of the cleaning brush. Furthermore, the rotation of the cleaning brush is also difficult to completely remove the ice residue attached to the track surface, affecting the accuracy of track flaw detection.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
