Description

Technical Field

[0001] The invention relates to the technical field of rail maintenance, and in particular to a grinding device for high-speed rail grinding based on a CBN grinding wheel. Background Art

[0002] As a vital component of the railway transportation system, rails play a key role in carrying the weight of trains and guiding the direction of train travel. They directly bear the huge pressure and continuous friction caused by the high-speed operation of trains. During long-term use, rails will have defects such as wear and cracks. Wear is the most common problem. Due to long-term friction with the wheels, the surface of the rails will gradually become thinner, affecting its carrying capacity. The appearance of cracks may be due to stress concentration, material aging and other reasons. If not handled in time, the cracks will continue to expand, seriously threatening the safety of train operation. In addition, the rails may also deform, such as bending and twisting, which will cause bumps when the train is running and reduce the stability of operation. Therefore, regular grinding and maintenance are required to ensure the safety and stability of train operation.

[0003] At present, the devices used for rail grinding mainly include traditional grinding wheel grinding devices, PGM-48 rail grinding trains, RGH20C turnout grinding trains, etc. Traditional grinding wheel grinding devices, PGM-48 rail grinding trains, and RGH20C turnout grinding trains mostly use ordinary corundum abrasives.

[0004] When ordinary corundum abrasives are used to grind rails, the grinding edge of the grinding wheel is consumed quickly and easily blunted, resulting in a decrease in its cutting ability. The grinding tool needs to be replaced more frequently, which affects the efficiency of rail grinding. In addition, ordinary corundum abrasives will generate a large amount of dust in the process of grinding rails. In addition to the iron filings generated by grinding rails, these dusts also contain a large amount of abrasives, adhesive materials, etc., which is not only difficult to effectively recycle the iron filings, but also produce odors that pollute the construction environment. The generated dust and odors will affect the operator's vision and working environment, and even cause harm to the operator's health.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] The embodiment of the present application discloses a grinding device for high-speed grinding of rails based on a CBN grinding wheel.

[0034] Please refer to Figures 1 to 8 In one embodiment of the present application, a grinding device for high-speed grinding of rails based on a CBN grinding wheel includes a carrier 100, and the carrier 100 includes a base plate 101. The bottom of the base plate 101 is rotatably connected to a wheel axle 102 near its two ends, and the wheel axle 102 is fixedly connected to its two ends. A driving member 104 is fixedly connected to the base plate 101, and a driving gear 105 is fixedly connected to the output shaft of the driving member 104. A driven gear 106 is fixedly installed on one of the two wheel axles 102 corresponding to the driving gear 105, and the driving gear 105 is meshed with the driven gear 106.

[0035] During operation, the driving member 104 can drive the driving gear 105 to rotate, and the driving gear 105 can drive the axle 102 to rotate through the driven gear 106. After the axle 102 rotates, it will drive the carrier 100 as a whole to move on the rail 900 through the roller 103.

[0036] Please refer to Figures 1 to 8 In one embodiment of the present application, a plurality of lateral moving assemblies 200 are symmetrically installed on both sides of the carrier 100 corresponding to the rails 900, and the lateral moving assemblies 200 are each installed with a swinging assembly 300, and the swinging assembly 300 is each installed with a longitudinal moving assembly 400, and the longitudinal moving assembly 400 is installed with a grinding assembly 500, and the grinding assembly 500 is detachably connected to a CBN grinding wheel 600.

[0037] During operation, the carrier 100 can be used to drive the lateral moving assembly 200, the swing assembly 300, the longitudinal moving assembly 400, the grinding assembly 500 and the CBN grinding wheel 600 to move on the rail 900 as a whole. During the movement, the carrier 100 will drive the grinding assembly 500 and the CBN grinding wheel 600 to move along the rail 900, thereby providing a feed motion for the CBN grinding wheel 600 when grinding the rail 900, thereby ensuring stable and reliable grinding of the rail 900. The grinding assembly 500 and the CBN grinding wheel 600 can be controlled to grind the rail 900 at a set angle through the cooperation of the lateral moving assembly 200 and the swing assembly 300. The depth of grinding the rail 900 can be effectively controlled through the longitudinal moving assembly 400.

[0038] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the CBN grinding wheel 600 is a super-hard grinding wheel made of cubic boron nitride. Cubic boron nitride is a super-hard material synthesized by humans, which is second only to diamond in hardness and far higher than ordinary corundum and silicon carbide abrasives. Therefore, it has better cutting ability and service life, and can easily grind and maintain the rail 900. The iron filings generated during the grinding process are also of higher purity. This avoids frequent replacement of the grinding wheel, improves the efficiency of grinding the rail 900, and avoids the generation of a large amount of dust and odor. In addition, the iron filings generated during the grinding process can be effectively collected through the iron filing recovery component 700, which not only improves the recycling of iron filings, but also reduces the negative impact on the environment and protects the construction environment of the staff.

[0040] During operation, the first telescopic member 201 is used to extend and retract to drive the sliding frame 202 to move in the vertical direction of the rail 900. The position of the swing assembly 300 can be adjusted by controlling the movement of the sliding frame 202. This not only controls the depth of grinding the side of the rail 900 by the CBN grinding wheel 600 during operation, but also adjusts the position of the CBN grinding wheel 600 during loading, unloading or replacing the CBN grinding wheel 600 to facilitate disassembly and assembly operations.

[0041] Please refer to Figures 1 to 8In a specific embodiment of the present application, the first telescopic member 201 is configured as a linear motor. The linear motor has extremely high precision and speed during operation, and can achieve very high acceleration and fast response. Moreover, there is no mechanical contact, and linear motion is directly generated during operation without an intermediate transmission mechanism, which reduces friction and wear, and improves the reliability and life of the system. At the same time, the linear motor can be operated by remote control, buttons or automatic control systems during operation, and is easy to realize remote control and automatic control.

[0042] It is understandable that in other specific embodiments of the present application, the first telescopic member 201 can also be configured as a structure or device that can generate linear motion, such as an electric push rod, a ball screw, or a hydraulic cylinder.

[0043] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the swing assembly 300 includes a swing frame 301, the swing frame 301 is rotatably connected to the sliding frame 202, a second telescopic member 302 is hingedly connected to the swing frame 301 at a position away from the sliding frame 202, one end of the second telescopic member 302 away from the swing frame 301 is hingedly connected to a position on the sliding frame 202 away from the swing frame 301, and the longitudinal moving assembly 400 is installed on the swing frame 301.

[0044] During operation, the second telescopic member 302 is extended and retracted to drive the swing frame 301 to swing relative to the sliding frame 202, and the swing frame 301 drives the longitudinal moving component 400 to swing, so that the angle of the CBN grinding wheel 600 can be adjusted so that the CBN grinding wheel 600 can grind the inclined surface of the rail 900 during operation.

[0045] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the second telescopic member 302 is configured as a linear motor.

At the same time, the linear motor can be operated by remote control, buttons or automatic control systems during operation, and is easy to realize remote control and automatic control.

[0046] It is understandable that in other specific embodiments of the present application, the second telescopic member 302 may also be configured as a structure or device that can generate linear motion, such as an electric push rod, a ball screw, or a hydraulic cylinder.

[0047] Please refer to Figures 1 to 8In a specific embodiment of the present application, the longitudinal moving component 400 includes a servo motor 401 fixedly mounted on the swing frame 301, a sleeve 402 is screwed on the output shaft of the servo motor 401, the sleeve 402 is fixedly connected to the grinding component 500, a slider 403 is fixedly connected to the grinding component 500, a slide groove 404 is provided on the swing frame 301 corresponding to the slider 403, and the grinding component 500 and the swing frame 301 are slidably connected through the slider 403 and the slide groove 404.

The servo motor 401 has high control accuracy, good high-speed performance, strong overload resistance, fast dynamic response, low-speed stability, high reliability, long life, and energy saving and high efficiency. Therefore, the servo motor 401 can be used to accurately and reliably control the grinding assembly 500 to drive the CBN grinding wheel 600 to grind the rail 900.

[0049] Please refer to Figures 1 to 8 In a specific embodiment of the present application, a limiting post 405 is fixedly connected to the output shaft of the servo motor 401, and a spiral groove 406 is provided inside the sleeve 402 corresponding to the limiting post 405, and the limiting post 405 is slidably connected to the spiral groove 406. During operation, when the output shaft of the servo motor 401 rotates, the limiting post 405 will slide relatively inside the spiral groove 406, and the sleeve 402 will move along the axial direction of the servo motor 401.

[0050] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the grinding assembly 500 includes a grinding motor 501, a sleeve 402 is fixedly mounted on the end of the grinding motor 501, a slider 403 is fixedly connected to the side of the grinding motor 501, and a mounting frame 502 is detachably connected to the output shaft of the grinding motor 501 through a transmission connection, and a CBN grinding wheel 600 is detachably mounted on the mounting frame 502.

[0051] During operation, the grinding motor 501 can drive the mounting frame 502 to rotate, and the mounting frame 502 will drive the CBN grinding wheel 600 to rotate. Through the setting of the mounting frame 502, different types of grinding wheels can be replaced more conveniently and reliably to grind the rail 900.

[0052] Please refer to Figures 1 to 8In a specific embodiment of the present application, the CBN grinding wheel 600 includes an end grinding wheel 601 and a side grinding wheel 602. The abrasive of the end grinding wheel 601 is arranged on the end face of the grinding wheel, and the abrasive of the side grinding wheel 602 is arranged on the side face of the grinding wheel. The end grinding wheel 601 can be used to conveniently grind the top surface of the rail, and the side grinding wheel 602 can be used to conveniently grind the side of the rail. Configuring the CBN grinding wheel 600 as the end grinding wheel 601 and the side grinding wheel 602 can more conveniently grind the top surface and side of the rail according to the grinding requirements, thereby reducing the difficulty of adjusting the grinding assembly 500 and the CBN grinding wheel 600 by the lateral moving assembly 200, the swinging assembly 300, and the longitudinal moving assembly 400 during operation.

The chip recovery assembly 700 includes a fixed frame 701 symmetrically arranged on both sides of the carrier 100. A first mounting plate 703 is fixedly connected to the fixed frame 701 corresponding to the rail 900. Both ends of the first mounting plate 703 are rotatably connected to a first transmission shaft 704. A first transmission motor 705 is transmission-connected to one of the first transmission shafts 704. A first roller 706 made of a magnetic material is fixedly connected to the first transmission shaft 704.

[0054] During operation, the first transmission motor 705 can drive the first transmission shaft 704 to rotate, and after the first transmission shaft 704 rotates, it will drive the first roller 706 to rotate, and the first roller 706 will drive the first conveyor belt 707 to operate. During the operation of the first conveyor belt 707, when the first conveyor belt 707 rotates to the side close to the rail 900, the first magnetic plate 708 and the first roller 706 will adsorb iron filings on the surface of the first conveyor belt 707; when the first conveyor belt 707 rotates to the side away from the rail 900, the first magnetic isolation plate 709 will block the adsorption of iron filings by the first magnetic plate 708, and at the same time, the scraping box 710 will scrape the iron filings inside the scraping box 710, and at this time, the vacuum cleaner 800 will suck out the iron filings inside the scraping box 710 through the first vacuum hose 711. This can effectively collect iron filings, not only preventing them from entering the gaps between equipment and affecting operation and grinding accuracy, but also reducing fire risks, reducing the possibility of personal injury, and maintaining a safe working environment; it is also conducive to recycling as scrap iron, reducing resource waste, and facilitating subsequent cleanup work, saving manpower and time costs.

Moreover, there is no mechanical contact, and linear motion is directly generated during operation without an intermediate transmission mechanism, which reduces friction and wear, and improves the reliability and life of the system. At the same time, the linear motor can be operated by remote control, buttons or automated control systems during operation, and is easy to achieve remote control and automated control.

On the side of the interior away from the carrier 100, the second magnetic isolation plate 717 is located on the side of the second conveyor belt 715 close to the carrier 100, and the bottom of the carrier 100 is fixedly connected to a scraper 718 that is slidably connected to the second conveyor belt 715. A through hole 719 is opened on the carrier 100 corresponding to the scraper 718, and a second dust suction hose 720 is fixedly and sealedly connected to the corresponding through hole 719 on the carrier 100. The end of the second dust suction hose 720 away from the through hole 719 is also connected to the vacuum cleaner 800, and a second transmission motor 721 is transmission-connected to one of the second transmission shafts 713.

[0059] During operation, the second conveying motor 721 can be used to drive the second conveying shaft 713 to rotate, and the second conveying shaft 713 will drive the second roller 714 to rotate. The rotation of the second roller 714 will drive the second conveyor belt 715 to operate. During the operation of the second conveyor belt 715, when the second conveyor belt 715 runs to the side facing the ground, the second magnetic plate 716 will adsorb iron filings on the ground onto the second conveyor belt 715. When the second conveyor belt 715 runs to the side facing the carrier 100, the second magnetic isolation plate 717 will isolate the second magnetic plate 716 from adsorbing iron filings. At the same time, the scraper 718 will collect the iron filings near the through hole 719. At this time, the vacuum cleaner 800 will suck out the iron filings collected by the scraper 718 through the second vacuum hose 720, thereby further increasing the effect and range of sucking out the iron filings.

[0060] In a specific embodiment of the present application, the first conveyor belt 707 and the second conveyor belt 715 are made of flexible materials that do not isolate magnetism, such as rubber, woven fabric, etc. During operation, when the first conveyor belt 707 and the second conveyor belt 715 are close to the first magnetic plate 708 or the second magnetic plate 716, iron filings can be stably and reliably adsorbed; when the first conveyor belt 707 and the second conveyor belt 715 are close to the first magnetic isolation plate 709 and the second magnetic isolation plate 717, the adsorption of iron filings can be isolated in time.

[0061] Please refer to Figures 1 to 8In a specific embodiment of the present application, the vacuum cleaner 800 includes a dust box 801, which is fixedly mounted on the carrier 100, and a fan 802 is fixedly mounted on the outer end of the dust box 801 facing the carrier 100, and a first dust hose 711 and a second dust hose 720 are fixedly and sealedly connected to one end of the dust box 801 away from the fan 802, and a plurality of staggered partition plates 803 are fixedly connected to the interior of the dust box 801 at a position between the fan 802 and the first dust hose 711 and the second dust hose 720, and a magnet 804 is fixedly mounted on the interior of the dust box 801 below the partition plate 803, and a detachable drawer 805 is slidably connected to the interior of the dust box 801 at the upper part of the magnet 804.

[0062] During operation, the air inside the dust box 801 can be blown out by the fan 802, and negative pressure will be formed inside the dust box 801. The negative pressure inside the dust box 801 will suck the iron filings collected by the scraper box 710 and the scraper 718 into the dust box 801 through the first dust suction hose 711 and the second dust suction hose 720. After the iron filings enter the dust box 801, they will hit the partition plate 803. At the same time, the magnet 804 fixedly installed below the partition plate 803 will adsorb the iron filings inside the drawer 805. On the one hand, adsorbing the iron filings inside the drawer 805 facilitates centralized processing of the iron filings, which is more efficient and convenient for both recycling and disposal. On the other hand, adsorbing the iron filings inside the drawer 805 can keep the working environment clean and prevent the iron filings from scattering.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
