Description

Technical Field

[0001] This utility model belongs to the field of railway maintenance, specifically a rail cleaning device. Background Technology

[0002] During long-term use, railway tracks are affected by natural factors and train operation, and various debris will accumulate in different parts: loose debris such as fallen leaves and snow will accumulate on the top surface of the tracks; heavier particles such as sand and coal slag will accumulate in the gaps between the sleepers; and stubborn dirt such as oil and rust will easily adhere to the sides of the tracks and bolt connections.

[0003] Existing rail cleaning devices are significantly inadequate in addressing the need to clean various types and locations of debris. Most devices employ a single cleaning structure with uniformly long bristles, which, while effective at removing loose debris from the top surface of the rails, struggles to reach the deeper gaps between sleepers, leaving sand and gravel residue. Furthermore, traditional devices generally lack specialized cleaning structures for the rail sides and bolted connections, leaving stubborn contaminants such as oil and rust in these areas unremoved. This incomplete cleaning leads to sand and gravel accumulation in the sleeper gaps, affecting track drainage and accelerating sleeper corrosion; the oil and rust remaining on the rail sides alter the friction coefficient of the wheel-rail contact surface, impacting train braking performance. Utility Model Content

[0004] The purpose of this utility model is to provide a rail cleaning device to solve the problems of existing rail cleaning devices that do not thoroughly clean the gravel between sleepers and cannot clean the debris on the sides of the rails and at the bolts, resulting in low cleaning efficiency and affecting the railway maintenance effect.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] As attached Figure 1 To be continued Figure 3 As shown:

[0029] This utility model provides a railway track cleaning device, including a traction connection unit 1, a cleaning support unit 2, a main cleaning component 3, a height adjustment unit 4, an auxiliary cleaning component 5, and a rotary drive component 6. The traction connection unit 1 is used for fixed connection with a railway locomotive, including a traction frame 101 (made of Q345 steel), which is connected to the bottom mounting point of the locomotive by high-strength bolts. The lower surface of the middle part of the traction frame 101 is hinged to the cleaning support unit 2 by a hinge. The cleaning support unit 2 is an arc-shaped carbon steel cover with an opening facing downwards and fastened above the rail. The cover has reinforcing ribs on both sides to enhance rigidity. The main cleaning component 3 is a snow removal roller, which is rotatably connected to the inner wall of the cleaning support unit 2 by bearings at both ends. The outer circumference is covered with a wear-resistant nylon brush. The bristles on the inner side of the area corresponding to the gap between the sleepers are thickened to thoroughly clean the sand and gravel in the gaps. The height adjustment unit 4 has two sets, which are symmetrically fixed to the bottom of the traction frame 101 on both sides of the traction connection unit 1 by bolts. Each set includes a support plate 401 and a lifting drive component 402. The auxiliary cleaning component 5 has two sets, which are respectively fixed to the lower surface of the support plate 401 of the two sets of height adjustment units 4 by screws. Each set includes a cleaning roller brush 501 and a transmission unit 502 for cleaning the side of the rails and bolt connections. The rotary drive component 6 is fixed to the upper surface of the support plate 401 by a motor bracket. The output shaft is fixedly connected to the drive wheel of the transmission unit 502 by a coupling for driving the auxiliary cleaning component 5 to operate.

[0030] During operation, the workers first secure the traction frame 101 of the traction connection unit 1 to the mounting point at the bottom of the railway locomotive using bolts, ensuring the bolts are tight. Next, the lifting drive 402 of the height adjustment unit 4 is adjusted to ensure the cleaning roller brush 501 of the auxiliary cleaning component 5 adheres to the side of the rail (with moderate pressure to avoid excessive tightness and rail wear). The rotation drive 6 is activated, driving the cleaning roller brush 501 to rotate via the transmission unit 502. Then, the telescopic drive 102 of the traction connection unit 1 is adjusted to ensure the brush bristles of the main cleaning component 3 of the cleaning bearing unit 2 adhere to the top surface of the rail. As the locomotive travels at a suitable speed, the main cleaning component 3 rotates with the friction of the rail top surface, and the thickened bristles on the inner side penetrate into the gaps between the sleepers, sweeping sand and gravel to the track bed. Simultaneously, the auxiliary cleaning roller brush 501 cleans oil stains, rust, and debris from bolts on the side of the rail. This three-dimensional cleaning of the "top surface + gaps + sides" significantly reduces the debris residue rate compared to traditional devices that only clean the top surface, making it suitable for standard rails.

[0031] As attached Figure 1 To be continued Figure 3As shown: In one embodiment of this utility model, the traction connection unit 1 includes a traction frame 101, a telescopic drive component 102, a connecting plate 103, and a swing arm 104. One end of the traction frame 101 is connected to the railway locomotive by bolts, and the other end is hinged to the cleaning and bearing unit 2 by hinges. The telescopic drive component 102 is a double-acting hydraulic push rod, with two symmetrically hinged on both sides of the traction frame 101. The movable end is hinged to the connecting plate 103 by a pin. The swing arm 104 is a steel rod, with one end hinged to the outer wall of the cleaning and bearing unit 2 by a pin, and the other end hinged to the end of the connecting plate 103 by a pin. The telescopic drive component 102 can extend and retract to drive the swing arm 104 to rotate around the hinge point, adjusting the tilt angle of the cleaning and bearing unit 2 (to adapt to the height difference of the rail top surface).

[0032] During operation, if the operator detects a height difference on the top surface of the rail, a signal is sent to the telescopic drive unit 102 via the locomotive control panel: when the high-sweeping support unit 2 needs to be raised, the hydraulic push rod extends, pushing the connecting plate 103 upward, causing the swing arm 104 to rotate upward around the hinge point of the sweeping support unit 2, ensuring the brush bristles of the main sweeping component 3 remain in contact with the top surface of the rail; when the rail needs to be lowered, the hydraulic push rod shortens, and the swing arm 104 rotates downward. The linkage between the telescopic drive unit 102 and the swing arm 104 enables adjustment of the sweeping angle, preventing the brush bristles from being suspended or subjected to excessive pressure wear due to rail height differences, thus adapting to most railway sections.

[0033] As attached Figure 2 To be continued Figure 3 As shown: In one embodiment of this utility model, the sweeping support unit 2 is an arc-shaped metal cover (Q235 carbon steel material), with the opening facing downwards and fastened to the top of the rail. Ventilation holes are provided at both ends of the cover (to prevent debris from splashing and accumulating during sweeping). The main sweeping component 3 is a snow removal roller (steel roller core, surface anti-rust treatment), with both ends rotatably connected to the inner wall of the sweeping support unit 2 through bearings with dust covers (adapting to outdoor dusty environments). The outer circumference of the snow removal roller is wrapped with wear-resistant nylon bristles, and the inner bristles of the corresponding sleeper gap area are thicker than the outer bristles of the corresponding rail top surface area (to match the width of the sleeper gap). A metal lining is provided at the root of the thickened bristles to enhance the bending resistance.

[0034] During operation, the first step is for the worker to install the main cleaning component 3 by pressing the outer ring of the bearing into the bearing seat of the cleaning support unit 2, and then installing the roller shaft into the inner ring of the bearing. As the locomotive moves, the roller rotates due to friction with the top surface of the rail, and the outer bristles sweep away dust and thin snow from the top of the rail. The thickened bristles on the inner side penetrate deep into the gaps between the sleepers, hooking out accumulated sand and gravel, which then slides along the inner wall of the curved cover to the track bed. Ventilation holes prevent excessive air pressure inside the cover from causing debris to splash backwards. Through the thickened bristle design, the cleaning rate of the sleeper gaps is significantly improved, and the metal lining reduces the breakage rate of the bristles.

[0035] As attached Figure 1 To be continued Figure 2 As shown: In one embodiment of this utility model, the brush bristles are in contact with the top surface of the rail and the inner wall of the gap between the sleepers, and the bristle compression is moderate (to ensure uniform sweeping force); the arc-shaped inner wall of the sweeping bearing unit 2 is adapted to the outer periphery of the main sweeping component 3, and the distance between the inner wall and the top of the brush bristles is reasonable, forming a "U-shaped guide channel" to limit the splashing of debris during the sweeping process; the edge of the arc-shaped cover opening is provided with a rubber strip, and the gap with the side of the rail is small, further preventing debris from overflowing.

[0036] During operation, after installing the cleaning support unit 2, the staff checks the gap between the rubber strip at the opening of the arc-shaped cover and the side of the rail to ensure the gap is small. During cleaning, the debris swept up by the main cleaning component 3 moves upward along the arc-shaped inner wall. Because the distance between the inner wall and the bristles is small, the debris cannot splash outward and can only slide down along the guide channel to the track bed. The rubber strip blocks the fine dust leaking from the side, preventing contamination of the rail bolts. Through the cooperation of the arc-shaped cover and the rubber strip, the debris splashing rate is greatly reduced, reducing pollution to surrounding equipment and preventing debris from getting stuck in the roller bearings.

[0037] As attached Figure 2 To be continued Figure 3 As shown: In one embodiment of this utility model, the height adjustment unit 4 includes a support plate 401 and a lifting drive component 402. The lifting drive component 402 is an electric push rod, the fixed end of which is fixedly connected to the bottom of the traction frame 101 of the traction connection unit 1 by bolts, and the end of the push rod is hinged to the ear plate on the upper surface of the support plate 401 by a pin. The lower surface of the support plate 401 is provided with threaded holes for fixing the auxiliary cleaning component 5. Guide holes are provided on both sides of the support plate 401, through which guide rods (fixed to the traction frame 101) are inserted to prevent the support plate 401 from shifting when it is raised or lowered.

[0038] During operation, the staff first sets the stroke of the lifting drive component 402 according to the cleaning needs of the rail side via the locomotive control panel: when cleaning the lower part of the rail side, the push rod extends, driving the support plate 401 to descend, and the cleaning roller brush 501 of the auxiliary cleaning component 5 fits against the lower part of the rail; when cleaning the bolted joints, the push rod is adjusted to the appropriate stroke, and the support plate 401 is in the middle position; the guide rod limits the offset of the support plate 401, ensuring that the roller brush always fits against the rail. Precise adjustment via the electric push rod adapts to different cleaning areas (the entire range of the rail side), significantly improving efficiency compared to manual adjustment.

[0039] As attached Figure 2 To be continued Figure 3As shown: In one embodiment of this utility model, the auxiliary cleaning component 5 includes a cleaning roller brush 501 and a transmission unit 502. The axis of the cleaning roller brush 501 is perpendicular to the length direction of the rail. The roller core is made of nylon, and the bristles on the outer circumferential surface are made of a mixture of elastic metal wire and nylon filament with a reasonable bristle density. The transmission unit 502 is a synchronous belt pulley set. The driving wheel is fixed to the output shaft of the rotary drive component 6 through a coupling, and the driven wheel is fixed to the end of the roller core of the cleaning roller brush 501 through a key connection. The two sets of cleaning roller brushes 501 are respectively attached to both sides of the rail (with moderate attachment pressure). The bristles at the rail bolts are provided with avoidance grooves to prevent collision with the bolts.

[0040] During operation, the operator first activates the rotary drive unit 6. The output shaft drives the drive wheel of the transmission unit 502 to rotate, which in turn drives the driven wheel via a synchronous belt, thus driving the cleaning roller brush 501 to rotate. The metal wire bristles polish rust and oil stains on the side of the rails, while the nylon bristles sweep away dust and fine grit. The clearance groove avoids rail bolts, preventing the roller brush from getting stuck or the bolts from wearing out. The mixed material bristles achieve a high rust and oil stain removal rate, and the clearance groove design prevents bolt collision damage, adapting to the layout of railway bolts.

[0041] As attached Figure 2 To be continued Figure 3 As shown: In one embodiment of this utility model, the rotary drive component 6 is a geared motor, the housing of which is fixedly connected to the upper surface of the support plate 401 of the height adjustment unit 4 by bolts. The motor shaft end is provided with a keyway and is fixedly connected to the coupling by a flat key. The other end of the coupling is fixed to the drive wheel shaft of the transmission unit 502. The output speed of the rotary drive component 6 can be adjusted by a frequency converter: when cleaning rust, the speed is adjusted to a higher speed (to enhance the grinding force), and when cleaning dust, the speed is adjusted to a lower speed (to reduce dust rising). A rubber shock-absorbing pad is provided between the motor housing and the support plate 401 to reduce vibration transmission and avoid affecting the life of the synchronous belt of the transmission unit 502.

[0042] During operation, the operator first adjusts the rotation speed according to the type of debris being swept: if there is a lot of rust on the side of the rails, the speed of the rotary drive component 6 is set to a higher value via the frequency converter, and the cleaning roller brush 501 polishes at high speed, causing the rust to fall off quickly; if only dust needs to be swept away, the speed is set to a lower value, and the nylon bristles gently sweep, causing the dust to fall into the track bed with the rotation of the roller brush without being stirred up again; the shock-absorbing pad reduces vibration and extends the life of the synchronous belt. By adjusting the rotation speed, different debris sweeping needs can be met, improving the sweeping effect and the durability of the components.

[0043] As attached Figure 1 To be continued Figure 2As shown: In one embodiment of this utility model, the traction connection unit 1 has two telescopic drive members 102, symmetrically distributed on both sides of the traction frame 101. The cylinder of each telescopic drive member 102 is hinged to the ear plate of the traction frame 101 by a pin, and the movable end is hinged to the middle ear plate of the connecting plate 103 by a pin. The two telescopic drive members 102 telescopically extend and retract (with small synchronization error), and are linked and controlled by the locomotive PLC controller to avoid tilting of the sweeping bearing unit 2 due to unilateral extension and retraction. The cylinder of the telescopic drive member 102 is provided with a protective sleeve (waterproof material) to prevent outdoor rainwater and dust from entering the cylinder and extend the life of the seals.

[0044] During operation, the staff first checks the synchronicity of the two telescopic drive components 102: the telescopic drive component 102 extends to a suitable stroke, and the height difference between the two connecting plates 103 is checked to ensure the difference is small; if a deviation exists, it is calibrated via the controller; during outdoor rainy weather operations, the protective cover prevents rainwater from entering the cylinder, avoiding corrosion of the seals; when adjusting the angle of the sweeping support unit 2, the two telescopic drive components 102 extend or shorten synchronously, the sweeping support unit 2 tilts smoothly, and the bristles of the main sweeping component 3 always adhere evenly to the top surface of the rail. Through the dual-drive synchronous design, the stability of the sweeping angle adjustment is greatly improved, and the protective cover extends the life of the drive components.

[0045] Working principle: Activating the telescopic drive component 102 pushes the swing arm 104 to rotate the sweeping bearing unit 2 downwards, causing the outer bristles of the main sweeping component 3 to adhere to the top surface of the rail. Activating the lifting drive component 402 moves the support plate 401 downwards, causing the sweeping roller brush 501 to adhere to the side of the rail. As the railway locomotive moves slowly, the main sweeping component 3 rotates against the top surface of the rail as the locomotive moves, causing the thickened inner bristles to penetrate into the gaps between the sleepers, sweeping sand and gravel to the ballast area outside the rail. Simultaneously, activating the rotation drive component 6 drives the sweeping roller brush 501 to rotate at high speed through the transmission unit 502, cleaning rust, oil, and small debris from the side of the rail. Debris at bolt connections is peeled off by the roller brush bristles.

[0046] After the cleaning operation is completed, turn off the rotary drive 6 and start the telescopic drive 102 and the lifting drive 402 to drive the cleaning support unit 2, the main cleaning component 3 and the auxiliary cleaning component 5 to reset upwards, so as to prevent the device from colliding with the rails when it is not cleaning.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
