Description

Technical Field

[0001] This utility model relates to the technical field of railway sand removal equipment, specifically a multi-functional track sand removal vehicle. Background Technology

[0002] In areas with strong winds and sandstorms, railways are frequently damaged, especially in Inner Mongolia and Xinjiang. During operation, sandstorms often bury the tracks, causing sand to accumulate and severely damage the roadbed. In these areas, sandstorms can bury rail connecting parts, sleepers, and track cores, affecting the normal operation and safety of the railway. Therefore, timely sand removal is essential.

[0003] Currently, railway sand removal work mainly adopts manual sweeping methods. When the sand accumulates to a certain extent, a large number of workers are organized to clear the accumulated sand from the tracks to both sides to ensure the normal operation of trains. Railway sand removal workers rush to the buried location and use shovels to remove the yellow sand burying the rails, sleepers, and connecting parts off the track, trying to lift the sand as high as possible and let the wind carry it away to prevent the sand from being blown back onto the track in a short time, until the sleepers and rail components are completely exposed from the sand. After the accumulated sand is cleared off the track, the yellow sand scattered on the rail surface also needs to be swept away with brooms. Sand is essential for ensuring good contact between train wheels and rails, guaranteeing safe train passage. However, manual cleaning methods suffer from drawbacks such as high labor intensity, poor working environment, long cleaning time, low efficiency, incomplete cleaning, and high costs. Furthermore, the tracks are prone to being buried again by sand after cleaning. The problem of large-scale sand accumulation and track burial on railway lines due to wind and sand is becoming increasingly serious. Large-scale sand accumulation can easily lead to track bed hardening, causing the tracks to lose elasticity, accelerating rail wear, reducing the lifespan of train equipment, and endangering train safety.

[0004] Therefore, in order to address the above problems, it is necessary to design a multi-functional railway sand cleaning vehicle that can integrate sand cleaning, sand collection, sand suction, and sand discharge to solve the above technical problems. Currently used sand cleaning vehicles do not have many sand cleaning devices specifically designed for railway tracks, and ordinary sand cleaning vehicles do not have complete functions. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional track sand cleaning vehicle that has a reasonable structural design, novel concept, convenient operation, easy processing, low processing and manufacturing cost, saves manpower, saves sand cleaning time, improves sand cleaning efficiency, and cleans sand more thoroughly. It is specifically used for cleaning sand on railway tracks in harsh environments and can integrate sand cleaning, sand collection, sand suction, and sand discharge.

[0006] This utility model discloses a multi-functional rail-mounted sand-clearing vehicle, comprising a vehicle body, wheels fixedly mounted on the bottom surface of the vehicle body, a control room located at the front end of the vehicle body, and control components installed in the control room; a sand-discharging auger mechanism fixedly mounted on the bottom surface of the vehicle body, a pneumatic sand-suction mechanism fixedly mounted on the surface of the vehicle body, a hydraulic pump station fixedly mounted on one side of the pneumatic sand-suction mechanism; the hydraulic pump station fixedly mounted on the surface of the vehicle body; a sand storage tank fixedly mounted on the surface of the vehicle body, a generator set fixedly connected to the side wall of the sand storage tank, and a conveying mechanism fixedly mounted on the sand storage tank.

[0007] The vehicle can run on the railway track surface. Operators operate the control components from the control room to control the operation of each device. The operation is convenient and quick. The entire device is powered by a generator set and is controlled by both a control panel and a wireless remote control to achieve forward, backward, up, down, stop, and emergency stop functions. It has comprehensive and diverse functions, achieving the goal of thoroughly cleaning sand from the railway track surface. It can improve sand removal efficiency, reduce the labor intensity of workers, and provide a solution for the industry to quickly clean sand from tracks. It has important research significance and application value for ensuring railway traffic safety.

[0008] The sand-discharging auger mechanism includes an auger, a housing, a sand-dredging plate, a hydraulic motor, a transmission chain, a centrifugal sand-throwing machine, and positioning wheels. The housing is fixedly installed on both sides of the bottom surface of the vehicle body, and the auger is connected between the two housings. The sand-dredging plate is fixedly connected to the auger. The auger is connected to the bottom end of the transmission chain, and the top end of the transmission chain is connected to a hydraulic motor. There are two hydraulic motors. Centrifugal sand-throwing machines are fixedly connected to the outer walls of both sides of the auger.

[0009] The sand-discharging auger mechanism is located on the bottom and front of the vehicle body. During vehicle operation, a hydraulic motor drives a transmission chain, which in turn drives the auger to rotate, discharging sand from the tracks and projecting it towards centrifugal sand-throwing machines. Centrifugal sand-throwing machines are fixedly connected to the outer walls of the auger on both sides, using centrifugal force to propel the sand particles transported by the auger up to 3 meters away at a specific speed and direction, thus achieving the function of discharging sand from the railway tracks and completing the initial sand-clearing operation. Two hydraulic motors are installed, and their forward and reverse rotation can be controlled to achieve various throwing operations. The sand-clearing function, in the absence of wind, uses two hydraulic motors rotating in opposite directions to simultaneously throw sand to both sides of the track. If there is wind on one side of the track, the two hydraulic motors can rotate forward or reverse simultaneously to clear sand on that side. Therefore, it can be used in open desert areas with strong winds and has a wide range of applications. The sand-clearing operation can be adjusted according to the specific wind direction. In case of emergency where the rails are buried by sand, it has the ability to quickly clear sand. By working together with the auger and the centrifugal sand thrower, it can quickly throw the sand inside and on both sides of the track to 2-3 meters to both sides of the track, allowing vehicles to pass through the buried track normally.

[0010] The pneumatic sand suction mechanism includes a high-pressure blower, a separator, a cyclone dust collector, a pipe, a suction nozzle, limit wheels, a hydraulic lift, and a support frame. The support frame is fixedly installed on the surface of the vehicle body. The high-pressure blower is fixedly installed on the surface of the support frame. The high-pressure blower is fixedly connected to the pipe. The cyclone dust collector is fixedly installed on the side wall of the pipe. The separator is fixedly connected to the surface of the cyclone dust collector. The surface of the hydraulic lift is connected to the hydraulic pump station. The suction nozzle is fixedly connected to the bottom surface of the hydraulic lift. Limit wheels are fixedly connected to the side wall of the suction nozzle.

[0011] A sand conveying device is fixedly installed on the bottom surface of the pneumatic sand suction mechanism.

[0012] The pneumatic sand suction mechanism further collects sand. Using a high-pressure blower as the power source, it sucks the yellow sand remaining on the track, especially the yellow sand on the rail bolts and sleepers, into the separator. After sand-air separation in the separator, the sand is transported to the sand storage box through the sand conveying device, and the gas separated from the separator flows into the atmosphere through a cyclone dust collector. The collection effect is good and can effectively clean the sand remaining in the track components.

[0013] A horizontal conveyor is fixedly connected to the side wall of the cyclone dust collector. A discharge port is provided on one side of the horizontal conveyor, and another horizontal conveyor is provided below the discharge port. The discharge port of the inclined conveyor extends to the surface of the sand storage box. The horizontal conveyor and the horizontal conveyor together form a sand conveying device.

[0014] The sand separated by the cyclone dust collector enters the horizontal conveyor. The sand in the horizontal conveyor enters the inclined conveyor through the discharge port. The collected sand can be transported to the sand storage box by the horizontal and inclined conveyors. It has a high degree of automation, saves time and labor, and is easy to operate.

[0015] The sand storage box is fixedly connected to two sides by a conveying mechanism. The conveying mechanism includes an upper rotating frame and a lower rotating frame. The upper rotating frame is hinged to the surface of the sand storage box, and the lower rotating frame is hinged to the inside of the sand storage box. Conveyors are fixedly installed inside the upper rotating frame and the lower rotating frame.

[0016] The conveying mechanism is located on the sand storage box. When the sand in the storage box reaches a certain amount, it can rotate along the storage box via the upper and lower rotating frames to discharge the sand stored in the storage box to a position 5-6 meters away from both sides of the track. When it is necessary to discharge sand, the upper and lower rotating frames can be opened. When not in use, the upper and lower rotating frames are located on both sides of the storage box, which meets the clearance requirements when railway vehicles are running and improves the safety of other railway vehicles.

[0017] The bottom surface of the vehicle body is fixedly equipped with a material-grabbing mechanism, which is located on both sides of the suction nozzle.

[0018] The material-grabbing mechanism is an auger structure installed at both the front and rear ends of the vehicle body. To improve the sand-grabbing efficiency of the pneumatic sand-absorbing device, a material-grabbing mechanism is added before the pneumatic sand-absorbing device. It can remove sand up to 1.2m deep and 70mm thick within the track, achieving all-round sand removal within the track. The sand can be transported to the pneumatic sand-absorbing device, where a high-pressure blower serves as the power source to suck the sand from the track into the separator. After sand-air separation in the separator, the sand is transported to the sand storage tank through the sand conveying device. The gas separated from the separator flows into the atmosphere through a cyclone dust collector, achieving good collection effect. The collected sand is then transported to the sand storage tank for storage through the sand conveying device.

[0019] The bottom surface of the hydraulic lift is fixedly connected to a rotary brush.

[0020] The rotating brush is installed in front of the material feeding mechanism and the pneumatic sand suction device. Its main function is to rotate the brush to loosen the sand. The material feeding mechanism can transport most of the sand in the track to the material box. The remaining sand is sucked into the sand box by the pneumatic sand suction device, which facilitates more efficient operation of the pneumatic sand suction device and further achieves the purpose of thoroughly cleaning the sand, realizing the operation of comprehensive sand cleaning of the track.

[0021] The beneficial effects of this utility model are:

[0022] 1) The vehicle body can run on the railway track surface. Operators operate the control components in the control room to control the operation of each device. The operation is convenient and quick. The entire device is powered by a generator set and is controlled by both a control panel and a wireless remote control to achieve forward, backward, up, down, stop, and emergency stop functions. It has comprehensive and diverse functions, achieving the goal of thoroughly cleaning sand from the railway track surface. It can improve sand cleaning efficiency, reduce the labor intensity of workers, and provide a solution for the industry to solve the problem of rapid track sand cleaning. It has important research significance and application value for ensuring railway traffic safety.

[0023] 2) The sand-discharging auger mechanism is located on the bottom and front of the car body. During car operation, a hydraulic motor drives a transmission chain, which in turn drives the auger to rotate. This displaces sand from the tracks and directs it towards centrifugal sand-throwing machines. Centrifugal sand-throwing machines are fixedly connected to the outer walls of the auger on both sides. Utilizing centrifugal force, these machines propel the sand from the auger up to a distance of 3 meters at a specific speed and direction, thus achieving the function of discharging sand from the railway tracks and completing the initial sand-clearing operation. Two hydraulic motors are installed, and their forward and reverse rotation can be controlled to achieve various functions. The sand-throwing function, in the absence of wind, uses two hydraulic motors rotating in opposite directions to simultaneously throw sand to both sides of the track. If there is wind on one side of the track, the two hydraulic motors can rotate forward or reverse simultaneously to achieve sand removal on that side. Therefore, it can be used in open desert areas with strong winds and has a wide range of applications. The sand-clearing operation can be adjusted according to the specific wind direction. In case of emergency where the rails are buried by sand, it has the ability to quickly clear sand. By working together with the auger and centrifugal sand thrower, it can quickly throw the sand inside and on both sides of the track to 2-3 meters to both sides of the track, allowing vehicles to pass through the buried track normally.

[0024] 3) The pneumatic sand suction mechanism can further collect sand. By using a high-pressure blower as the power source, the yellow sand left on the track, especially the yellow sand on the rail bolts and sleepers, is sucked into the separator. After sand-air separation in the separator, the sand is transported to the sand storage box through the sand conveying device, and the gas separated from the separator flows into the atmosphere through the cyclone dust collector. The collection effect is good and can achieve the function of cleaning the sand remaining in the track components.

[0025] 4) The sand separated by the cyclone dust collector enters the horizontal conveyor. The sand in the horizontal conveyor enters the inclined conveyor through the discharge port. The collected sand can be transported to the sand storage box by the horizontal conveyor and the inclined conveyor. It has a high degree of automation, saves time and labor, and is easy to operate.

[0026] 5) The conveying mechanism is located on the sand storage box. When the sand in the sand storage box reaches a certain amount, it can rotate along the sand storage box through the upper and lower rotating frames to discharge the sand stored in the sand storage box to a position 5-6 meters away from both sides of the track. When it is necessary to discharge sand, the upper and lower rotating frames can be opened. When not in use, the upper and lower rotating frames are located on both sides of the sand storage box to meet the clearance requirements when railway vehicles are running and improve the safety of other railway vehicles.

[0027] 6) The rotating brush is installed in front of the material feeding mechanism and the pneumatic sand suction device. Its main function is to rotate the brush to loosen the sand. The material feeding mechanism can transport most of the sand in the track to the material box. The remaining sand is sucked into the sand box by the pneumatic sand suction device, which makes the pneumatic sand suction device work more efficiently and further achieves the purpose of thoroughly cleaning the sand and realizing the operation of comprehensive sand cleaning of the track.

[0028] 7) The structure is rationally designed, innovative in concept, easy to operate, and readily processed. It boasts low manufacturing costs, saves manpower and time on sand removal, and improves sand removal efficiency, resulting in more thorough sand removal. Specifically designed for railway track sand removal in harsh environments, it integrates multiple functions including sand removal, collection, suction, and discharge. Its compact design, high degree of automation, safety, and environmental friendliness enhance sand removal efficiency and reduce worker labor intensity. Dual control via wireless remote control and visual operation provides convenience and flexibility, enabling forward, backward, upward, downward, stop, and emergency stop functions. This ensures that if one function fails, the other can continue to control the track. Visual operation allows real-time monitoring of sand collection and discharge, while wireless remote control allows for operation from within 100 meters of the track, ensuring high personnel safety.

If there is wind on one side of the track, the two hydraulic motors 16 can simultaneously rotate forward or reverse to achieve the function of sand removal on that side. A high-pressure blower 21 is used as the power source to suck up the remaining yellow sand on the track, especially the yellow sand on the rail bolts and sleepers, into the separator 22. After sand-air separation in the separator 22, the sand is transported to the sand storage box 8 through the sand conveying device 5, and the gas separated from the separator 22 flows into the atmosphere through the cyclone dust collector 23. The sand separated by the cyclone dust collector 23 enters the horizontal conveyor 27. The sand in the horizontal conveyor 27 enters the inclined conveyor 28 through the discharge port 2701. The collected sand is transported to the sand storage box 8 by the horizontal conveyor 27 and the inclined conveyor 28. When the sand in the sand storage box 8 reaches a certain amount, it can be rotated along the upper rotating frame 30 and the lower rotating frame 32 to discharge the sand stored in the sand storage box 8 to a position 5-6 meters away from both sides of the track through the conveyor 31. When it is necessary to discharge sand, the upper rotating frame 30 and the lower rotating frame 32 can be opened. When not in use, the upper rotating frame 30 and the lower rotating frame 32 are located on both sides of the sand storage box 8 to meet the clearance requirements when railway vehicles are running and improve the safety of other railway vehicles.

[0057] The material-grabbing mechanism 6 is an auger structure installed at both ends of the bottom of the car body 1. In order to improve the sand suction efficiency of the pneumatic sand suction device 4, the material-grabbing mechanism 6 is added before the pneumatic sand suction device. It can remove sand within 1.2m and 70mm thick in the track, achieving all-round sand removal in the track. The sand can be transported to the pneumatic sand suction device 4. The high-pressure blower 21 is the power source to suck the sand in the track into the separator 22. After sand and gas separation in the separator 22, the sand is transported to the sand storage box 8 through the sand conveying device 5. The gas separated from the separator 22 flows into the atmosphere through the cyclone dust collector 23, with good collection effect. The collected sand is then transported to the sand storage box 8 for storage through the sand conveying device 5.

[0058] The rotating brush 7 is installed in front of the material feeding mechanism 6 and the pneumatic sand suction device 4. Its main function is to rotate the rotating brush 7 to loosen the sand. The material feeding mechanism 6 can transport most of the sand in the track to the material box 8. The remaining sand is sucked into the sand box by the pneumatic sand suction device 4, which makes the pneumatic sand suction device 4 work more efficiently and further achieves the purpose of thoroughly cleaning the sand and realizing the operation of comprehensive sand cleaning of the track.
