Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] A portable railway rail surface sand cleaner includes a chevron-shaped sand removal head 1 and a housing 2. The rear end of the chevron-shaped sand removal head 1 is detachably connected to the front end of the housing 2. The chevron-shaped sand removal head 1 is used to clean the accumulated sand on the railway rail surface. Two limit wheels 3 arranged in the front and rear are provided on both the left and right sides of the housing 2, and the limit wheels 3 are used to clamp the rail. Through its unique shape, the chevron-shaped sand removal head 1 can more effectively scrape off the accumulated sand, improving the efficiency and effect of sand cleaning. The housing 2, as the main structure of the entire sand cleaner, provides support and connection functions, ensuring stability and safety during operation. The detachable connection method between the chevron-shaped sand removal head 1 and the housing 2 makes the device easy to disassemble and assemble, facilitating carrying and replacement. The limit wheels 3 provided on both sides of the housing 2 can clamp the rail, effectively limiting the distance from the rail, enabling the sand cleaner to remain stable during sand cleaning, avoiding shaking or tipping over of the device during sand cleaning, and improving the safety and stability of operation.
[0025] A support wheel 4 is rotatably connected to the bottom end of the chevron-shaped sand removal head 1, and the rear ends on both sides of the chevron-shaped sand removal head 1 extend downward and fit against the outer side surface of the rail. The setting of the support wheel 4 enables the chevron-shaped sand removal head 1 to move more smoothly along the rail during the cleaning process and rotate as the sand cleaner moves. The design of the chevron-shaped sand removal head 1 fits against the outer side surface of the rail, ensuring the stable movement of the chevron-shaped sand removal head 1.
[0026] The front roller 5 and the rear roller 6 are respectively rotatably connected to the inner side wall of the housing 2 in the front-rear direction. A support body 7 is rotatably connected to the inner side wall of the housing 2. The support body 7 is located behind the front roller 6. A push rod 8 and a sleeve plate 9 are fixedly connected to the circumferential surface of the support body 7. The sleeve plate 9 is located behind the push rod 8, and a sliding rod 10 is slidably connected in the sleeve plate 9. The arrangement of the front roller 5 and the rear roller 6 further enhances the moving stability and flexibility of the sand cleaner on the rail, enabling the sand cleaner to move along the rail more easily. At the same time, it also helps to remove more stubborn accumulated sand. The operator pushes the push rod 8 forward on the rail surface to remove the accumulated sand, reducing the labor intensity of the manual sand cleaning workers.
[0027] Special-shaped grooves 11 and arc-shaped grooves 12 are formed on both the left and right sides of the sleeve plate 9. The special-shaped grooves 11 and the arc-shaped grooves 12 are communicated. The sliding rod 10 can slide in the special-shaped grooves 11 and the arc-shaped grooves 12. By sliding the sliding rod 10 in the special-shaped grooves 11 and the arc-shaped grooves 12 of the sleeve plate 9, the telescoping and fixing of the U-shaped clamp 18 are realized.
[0028] One end of the sliding rod 10 away from the sleeve plate 9 is fixedly connected with a first plate body 13. The first plate body 13 includes a first connecting plate 13.1 and a traction plate 13.2. A rotating shaft 14 is rotatably connected between the two first connecting plates 13.1. The rotating shaft 14 is rotatably connected with the traction plate 13.2. A second connecting plate 15 is provided at the rear side of the traction plate 13.2. A cavity 16 is formed at the end of the second connecting plate 15. The rear end of the traction plate 13.2 is slidably connected in the cavity 16 of the second connecting plate 15. A spring 17 is installed at the tail end of the traction plate 13.2. One end of the spring 17 away from the traction plate 13.2 is fixedly connected to the inner wall of the cavity 16. The rear end of the second connecting plate 15 is rotatably connected with a U-shaped clamp 18. Two U-shaped clamps 18 are arranged up and down. By controlling the push rod 8, the sliding rod 10 slides in the special-shaped grooves 11 and the arc-shaped grooves 12 of the sleeve plate 9. Through the elastic action of the first plate body 13, the second connecting plate 15 and the spring 17, the telescoping and fixing of the U-shaped clamp 18 are realized. The U-shaped clamp 18 is used to clamp the rail to ensure the stability of the sand cleaner during the cleaning process and prevent it from tipping over during the cleaning process.
[0029] A connecting rod 19 is slidably connected to the housing 2. The two ends of the connecting rod 19 extend downward to the outer side surface of the rail. The U-shaped clamp 18 is rotatably connected to the connecting rod 19. A limiting wheel 3 is fixedly connected to the bottom end of the connecting rod 19. The connecting rod 19 connects the U-shaped clamp 18 and the limiting wheel 3. By adjusting the opening and closing degree of the U-shaped clamp 18, the clamping of the limiting wheel 3 on the outer side surface of the rail is controlled.
[0030] A support 20 is fixedly connected to the outer rear end of the housing 2. A support plate 21 is fixedly connected to the inner side wall at the tail end of the housing 2. The support 20 is used to fix the entire sand cleaner, and the support plate 21 provides additional support force to enhance the stability of the structure.
[0031] During the sand removal operation, place the sand cleaner on the railway rail surface, keep the sliding rod 10 in the special-shaped groove 11, pull the push rod 8 backward, so that the sliding rod 10 enters the arc-shaped groove 12 to form a lock. Push the push rod 8 forward to drive the first plate body 13 to move forward and pull the second connecting plate 15, and then pull the U-shaped clamp 18 to contract inward and pull the connecting rod 19, driving the limiting wheel 3 to move toward the outer side wall of the rail, clamping on both sides of the rail. Then push the push rod 8 again, and the supporting wheel 4, the front roller 5 and the rear roller 6 move forward on the rail, and the herringbone sand removal head 1 is used to clean the accumulated sand on the railway rail surface. The accumulated sand falls outside the railway rail surface after passing through the side wall of the herringbone sand removal head 1.
[0032] After the sand removal operation is completed, push the push rod 8 forward, so that the sliding rod 10 is located in the special-shaped groove 11, drive the first plate body 13 to move backward and push the second connecting plate 15, and then push the U-shaped clamp 18 to open outward and push the connecting rod 19. After driving the limiting wheel 3 to move away from the outer side surface of the rail, then take the sand cleaner away from the railway rail surface.
[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
