Description

Technical Field

[0001] This utility model relates to the technical field of rail grinding devices, specifically a rail grinding device for urban rail transit. Background Technology

[0002] Railway transportation is a land-based transportation network. Trains are pulled by locomotives and travel on rails, with the transmission of power through wheel hubs. This is called rail transport. The rails provide a smooth and hard medium for the train wheels to move along a fixed route. However, after prolonged use, railways inevitably develop rust, and the rails, exposed to the elements for extended periods, accumulate impurities and dust, reducing their smoothness and finish. Furthermore, existing rail grinding equipment is often designed for single rails, making it slow and inconvenient to use for rails with varying spacing. Utility Model Content

[0003] The purpose of this invention is to provide a rail grinding device for urban rail transit, so as to solve the problem mentioned in the background art that the grinding device cannot be used on rails with different spacings.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rail grinding device for urban rail transit, comprising a flatbed, sliding blocks slidably mounted on the outer surfaces of both ends of the flatbed, and wheels rotatably mounted on the outer surfaces of the sliding blocks, with the outer surfaces of the wheels in contact with the outer surfaces of the rails; a positioning motor fixedly mounted on the outer surface of the flatbed, with the output end of the positioning motor rotatably connected to the flatbed; a first screw rotatably mounted inside the flatbed, with the two ends of the first screw having opposite thread directions; the two ends of the first screw being threadedly connected to the sliding blocks respectively; a worm gear fixedly mounted on the outer surface of one end of the first screw; and a worm rotatably mounted inside the flatbed, with the worm connected to the positioning motor.

[0005] Preferably, a drive motor is fixedly installed on the side surface of the sliding block near the adjustment motor, and the output end of the drive motor is connected to the wheel.

[0006] By adopting the above technical solution, the rotation of the drive motor can drive the wheel to rotate, so that the wheel can rub against the rail to drive the grinding device to move slowly.

[0007] Preferably, sliders are slidably mounted on the outer surfaces of both ends of the flatbed, and a mounting cover is slidably mounted on the end of the slider closest to the rail. Screws are threaded onto the outer surface of the slider, and the screws of the slider are in contact with the outer surface of the mounting cover. A second screw is rotatably mounted on the outer surface of the flatbed, and the threads at both ends of the second screw rotate in opposite directions. Both ends of the second screw are threadedly connected to the slider.

[0008] By adopting the above technical solution, the distance and height between the mounting cover and the rail can be adjusted according to the height of the rail, so as to facilitate the grinding of rails with different distances and heights to remove rust.

[0009] Preferably, a grinding motor is fixedly mounted on the outer surface of the mounting cover, and the output end of the grinding motor penetrates through the outer surface of the mounting cover. A top grinding disc is fixedly mounted on the output end of the grinding motor, and the top grinding disc is located inside the mounting cover. The outer surface of the top grinding disc is in contact with the outer surface of the rail. A meshing mechanism is provided between the mounting cover and the grinding motor.

[0010] By adopting the above technical solution, the rotation of the mounting cover can drive the top grinding disc to rotate, so as to grind the top of the rail. At the same time, the mounting cover can wrap the rail, so that rust, dust and impurities will not fly around when the rail is being ground.

[0011] Preferably, the meshing mechanism includes: a main gear, which is fixedly installed at the output end of the grinding motor; auxiliary gears are rotatably installed on the outer surfaces of both ends of the mounting cover, and the auxiliary gears mesh with the main gear; a side grinding disc is fixedly installed at the output end of the auxiliary gear, and the outer surface of the side grinding disc is in contact with the outer surface of the rail.

[0012] By adopting the above technical solution, the rotation of the grinding motor can drive the main gear to rotate, causing the auxiliary gear meshing with the main gear to rotate together. The diameter difference between the auxiliary gear and the main gear allows the side grinding discs to rotate faster, thereby better cleaning and removing rust and impurities from the rail surface.

[0013] Preferably, a cleaning brush is fixedly installed on the outer surface of the mounting cover, and the outer surface of the cleaning brush is in contact with the outer surface of the rail. A through hole is opened on the outer surface of the mounting cover. A vacuum cleaner is fixedly installed on the outer surface of the flatbed, and the vacuum cleaner is connected to the through hole of the mounting cover. The mounting cover and the vacuum cleaner are connected by a corrugated hose.

[0014] Using the above technical solution, the cleaning brush can clean and remove the dust after the rail surface is polished. At the same time, the vacuum cleaner can also absorb and clean the air and the dust swept out during polishing, so that the dust generated during polishing will not be scattered everywhere, reducing the chance of dust being inhaled by workers during maintenance.

[0015] Preferably, an oiling brush is fixedly installed on the outer surface of the mounting cover away from the slider, and an electromagnetic oil storage can assembly is fixedly installed on the outer surface of the flat plate, and the electromagnetic oil storage can assembly is connected to the mounting cover.

[0016] By adopting the above technical solution, rust-preventive oil can be stored through an electromagnetic storage oil can assembly, and after the rail is polished, the rust-preventive oil can be released through the electromagnetic storage oil can assembly, so that the rust-preventive oil can be applied to the outer surface of the rail through an oiling brush, so that the rust-preventive oil can be applied after the rail is polished, reducing the chance of the rail rusting in the future.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the urban rail transit track grinding device:

[0018] 1. When maintaining and grinding the rails, simply rotate the worm gear by rotating the adjusting motor, which in turn rotates the worm wheel meshing with the worm gear. This worm wheel then drives the first screw to rotate, which in turn drives the sliding block to slide inside the flatbed. This allows the sliding block and the wheel to move together, and the wheel to fit against rails with different spacings. This allows the grinding device to travel and move on rails with different spacings, improving the practicality of the grinding device.

[0019] 2. After placing the grinding device on the surface of the rail, the second screw can be rotated to allow the slider to slide inside the flatbed, so that the mounting cover is positioned directly above the rail. Then, the distance between the mounting cover and the rail can be adjusted so that the mounting cover can be inserted into the rail and the top grinding disc can contact the surface of the rail. This allows for easy adjustment of the distance between the mounting cover and the top grinding disc, enabling grinding of rails with different spacing.

[0020] 3. When grinding the rails, simply start the grinding motor to rotate, which in turn drives the main gear to rotate. This causes the auxiliary gear, which meshes with the main gear, to rotate as well. The diameter difference between the auxiliary gear and the main gear accelerates the rotation speed of the side grinding discs. Combined with the use of the top grinding discs, this enhances the grinding effect on the rails. At the same time, a vacuum cleaner is used to absorb the dust generated during grinding inside the mounting cover, preventing the dust from spreading and being inhaled by the workers. This improves the grinding effect while also removing the dust generated during grinding. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-6This utility model provides a technical solution: a rail grinding device for urban rail transit, including a flatbed 1. Sliding blocks 2 are slidably installed on the outer surfaces of both ends of the flatbed 1, and wheels 3 are rotatably installed on the outer surfaces of the sliding blocks 2. The outer surfaces of the wheels 3 are in contact with the outer surfaces of the rails. A drive motor 4 is fixedly installed on the side surface of the sliding blocks 2 near the adjustment motor 6, and the output end of the drive motor 4 is connected to the wheel 3. The adjustment motor 6 is fixedly installed on the outer surface of the flatbed 1, and the output end of the adjustment motor 6 is rotatably connected to the flatbed 1. A first screw 5 is rotatably installed inside the flatbed 1, and the two ends of the first screw 5 have opposite thread directions. The two ends of the first screw 5 are respectively threadedly connected to the sliding blocks 2. A worm gear 8 is fixedly installed on the outer surface of one end of the first screw 5. A worm 7 is rotatably installed inside the flatbed 1, and the worm 7 is connected to the adjustment motor 6.

[0030] First, when using the grinding device, the adjusting motor 6 needs to be started. The rotation of the adjusting motor 6 drives the worm 7 to rotate, which in turn drives the worm wheel 8 that meshes with the worm 7 to rotate. The worm wheel 8 then drives the first screw 5 to rotate, allowing the sliding block 2 to slide on the surface of the flatbed 1. This adjusts the spacing of the wheels 3 according to the spacing of the rails, ensuring that the wheels 3 can be stably engaged with the side of the rails. This fixes the grinding device between rails with different spacings, improving its practicality. Then, the rotation of the drive motor 4 drives the wheels 3 to rotate slowly, allowing the grinding device to move along the rails for easy grinding of the rail surface, thus improving the overall practicality of the grinding device.

[0031] Slider 10 is slidably mounted on the outer surfaces of both ends of the flatbed 1, and mounting cover 11 is slidably mounted on the end of the slider 10 closest to the rail. Screws are threaded on the outer surface of the slider 10, and the screws of the slider 10 are in contact with the outer surface of the mounting cover 11. A second screw 9 is rotatably mounted on the outer surface of the flatbed 1, and the threads at both ends of the second screw 9 turn in opposite directions. Both ends of the second screw 9 are threadedly connected to the slider 10.

[0032] Secondly, after the grinding device is placed between the rails, the second screw 9 can be manually rotated to drive the slider 10 to rotate, allowing the slider 10 to slide on the surface of the flatbed 1, thereby driving the mounting cover 11 to rotate as well, so that the mounting cover 11 can be positioned above the rails. Then, the distance between the mounting cover 11 and the rails can be adjusted by tightening the screws, so as to facilitate grinding rails with different spacing and improve the practicality of the grinding device.

[0033] A grinding motor 12 is fixedly mounted on the outer surface of the mounting cover 11, and the output end of the grinding motor 12 passes through the outer surface of the mounting cover 11. A top grinding disc 13 is fixedly mounted on the output end of the grinding motor 12, and the top grinding disc 13 is located inside the mounting cover 11. The outer surface of the top grinding disc 13 is in contact with the outer surface of the rail. A meshing mechanism is provided between the mounting cover 11 and the grinding motor 12. The meshing mechanism includes: a main gear 14, which is fixedly mounted on the output end of the grinding motor 12; secondary gears 15 are rotatably mounted on the outer surfaces of both ends of the mounting cover 11, and the secondary gears 15 mesh with the main gear 14; a side grinding disc 16 is fixedly mounted on the output end of the secondary gear 15, and the outer surface of the side grinding disc 16 is in contact with the outer surface of the rail.

[0034] Once the position of the mounting cover 11 is adjusted, the grinding motor 12 can be started to drive the top grinding disc 13 to rotate, which in turn drives the main gear 14 to rotate. The rotation of the main gear 14 drives the auxiliary gear 15 to rotate, allowing the top grinding disc 13 and the side grinding disc 16 to rotate simultaneously. The rotation of the main gear 14 drives the diameter difference between the auxiliary gear 15, allowing the side grinding disc 16 to rotate faster. This allows the side grinding disc 16 to better grind the side of the rail, and the rails at both ends can be ground simultaneously, improving the grinding and cleaning effect and efficiency of the rail surface, and greatly enhancing the convenience and efficiency of the grinding device.

[0035] A cleaning brush 17 is fixedly installed on the outer surface of the mounting cover 11, and the outer surface of the cleaning brush 17 is in contact with the outer surface of the rail. A through hole is opened on the outer surface of the mounting cover 11. A vacuum cleaner 18 is fixedly installed on the outer surface of the flatbed 1, and the vacuum cleaner 18 is connected to the through hole of the mounting cover 11. A corrugated hose connects the mounting cover 11 and the vacuum cleaner 18. An oiling brush 19 is fixedly installed on the outer surface of the end of the mounting cover 11 away from the slider 10. An electromagnetic oil storage can assembly 20 is fixedly installed on the outer surface of the flatbed 1, and the electromagnetic oil storage can assembly 20 is connected to the mounting cover 11.

[0036] As the side grinding discs 16 and top grinding discs 13 grind the rails, a large amount of dust will be generated. At this time, with the start of the vacuum cleaner 18, the generated dust will be sucked into the vacuum cleaner 18 and the surface of the rails will be cleaned by the cleaning brush 17. This prevents the dust generated during the grinding of the rails from spreading around and being inhaled by the workers. After the grinding is completed, the rust-preventive oil will be released by the electromagnetic oil storage can assembly 20. The rust-preventive oil will enter the oiling brush 19 and be applied to the surface of the rails by the oiling brush 19. This greatly improves the practicality and safety of the grinding device.

[0037] Working principle: When grinding and finishing the rails, simply control the adjusting motor 6 to drive the worm gear 7 to rotate, causing the worm wheel 8 meshing with the worm gear 7 to rotate. This, in turn, drives the sliding block 2 to slide on the surface of the flatbed 1 via the first screw 5, allowing the position of the wheel 3 to be adjusted and engaged with the guide rail. Then, the rotation of the second screw 9 drives the slider 10 to slide inside the flatbed 1, moving the slider 10 and the mounting cover 11 above the rail. The distance between the mounting cover 11 and the rail can then be adjusted so that the top grinding disc 13 can fit against the surface of the rail. Finally, the drive motor 4 can be started to drive the car... The plate 1 moves along the outer surface of the rail, and then the rotation of the grinding motor 12 simultaneously drives the side grinding disc 16 and the top grinding disc 13 to rotate, allowing both rails to be ground and finished at the same time, ensuring the cleanliness of the rail surface. The dust generated during grinding is collected and absorbed by the vacuum cleaner 18, and the surface of the rail is cleaned by the cleaning brush 17. Then, the rust-preventive oil is released through the electromagnetic oil storage can assembly 20, and the rust-preventive oil is applied to the surface of the rail by the oiling brush 19 to improve the rust prevention effect of the rail, so that the grinding device can be used on rails with different spacing and to grind rails with different spacing.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
