Description

Technical Field

[0001] This utility model relates to the field of snow and ice removal for railway tracks, and more particularly to a snow and ice removal mechanism for railway tracks. Background Technology

[0002] In recent years, with the rapid development of China's railways, railway tracks are inevitably affected by natural weather during operation. In particular, snowfall greatly affects travel because heavy snow can cover the tracks, and snow accumulation on the track surface can easily cause derailment, thus affecting the travel and safety of passengers.

[0003] Traditional railway snow removal and de-icing equipment typically consists of scrapers and brushes mounted on rolling stock. During operation, the stock moves slowly along the rails, the scrapers directly contact the rail surface, and mechanically remove the snow. The brushes are used to sweep away any remaining snow and loose ice. Heated de-icing devices, on the other hand, utilize heating elements to raise the temperature of the rail surface through heat conduction, thereby melting the ice.

[0004] While traditional mechanical snow removal devices can remove some snow, they are ineffective at clearing large, compacted snow piles. Due to the structural and power limitations of the scraper, multiple round trips are often required when dealing with thick snow, resulting in low efficiency and a tendency to miss snow in corners and edges, leading to incomplete clearing and slow de-icing speed. This fails to meet the needs of railways for rapid restoration of normal operation. Therefore, a snow and ice removal mechanism for railway tracks is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a snow removal and de-icing mechanism for railway tracks, aiming to improve the problem of incomplete cleaning when facing thick snow accumulation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A snow removal and de-icing mechanism for railway tracks includes a snowplow body, with anti-skid tires fixedly connected to the outside of the snowplow body, an ice-breaking component installed on the outside of the snowplow body, and a snow removal component installed on the outside of the snowplow body.

[0008] The ice-breaking assembly includes an electric push rod, which is externally mounted on the bottom of the snowplow body. A support frame is fixedly connected to the end of the electric push rod, and an ice-breaking blade is rotatably connected inside the support frame. A second drive motor is fixedly connected to the outside of the support frame, and the ice-breaking blade is rotatably connected to the output end of the second drive motor.

[0009] As a further description of the above technical solution:

[0010] The snow removal assembly includes a drive motor, which is installed on the outside of the snow removal vehicle body. A blower is fixedly connected to the output end of the drive motor, and a directional port is fixedly connected to the end of the blower.

[0011] As a further description of the above technical solution:

[0012] A motor mount is fixedly connected to the outside of the snowplow body, a drive motor three is fixedly connected inside the motor mount, a connecting rod is fixedly connected to the output end of the drive motor three, and a sweeping brush is fixedly connected to the end of the connecting rod.

[0013] As a further description of the above technical solution:

[0014] A protective plate is fixedly connected inside the support frame, and the ice-breaking blade is rotatably connected to the inside of the protective plate.

[0015] As a further description of the above technical solution:

[0016] The connecting rod is externally rotatably connected to the middle part of the snowplow body;

[0017] As a further description of the above technical solution:

[0018] A brine tank is fixedly connected to the outside of the snowplow body, a water pump is fixedly connected inside the brine tank, a water pipe is fixedly connected to the output end of the water pump, and a nozzle is fixedly connected inside the water pipe.

[0019] As a further description of the above technical solution:

[0020] The water pipe is fixedly connected to a fixing frame, and the fixing frame is fixedly connected to the outside of the snowplow body.

[0021] As a further description of the above technical solution:

[0022] A connecting block is fixedly connected to the outside of the snowplow body, and a baffle is fixedly connected to the outside of the connecting block.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, a baffle pushes the snow inside the rails to both sides for initial snow dispersion. Then, an electric push rod pushes an ice-breaking blade close to the ice layer on the rails, activating a second drive motor. This motor causes the ice-breaking blade to rotate at high speed, using its blade to cut and break the ice into small pieces for subsequent processing. A protective plate prevents ice fragments from splashing and damaging the equipment during the ice-breaking process.

[0025] 2. In this invention, starting the drive motor drives the blower, causing a large amount of air to be drawn in and compressed to generate a powerful airflow. This airflow is then blown out through a directional nozzle to effectively remove ice fragments previously broken by the icebreaker and accumulated snow from the rail surface. This blown-off snow and ice fragments are dispersed to both sides of the rails, away from the track area, preventing them from accumulating back on the rails and affecting subsequent operations and railway safety. Finally, industrial brine is sprayed to help melt the remaining ice and snow, lowering their melting point and making them easier to melt into water, thereby further improving the overall snow and ice removal efficiency.

[0033] 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.

[0034] Reference Figure 1 and Figure 3 The present invention provides an embodiment of a snow removal and de-icing mechanism for railway tracks, comprising a snowplow body 1, an anti-skid tire 3 fixedly connected to the outside of the snowplow body 1, an ice-breaking component installed on the outside of the snowplow body 1, and a snow removal component installed on the outside of the snowplow body 1; the ice-breaking component includes an electric push rod 13, the electric push rod 13 is externally installed at the bottom of the snowplow body 1, a support frame 14 is fixedly connected to the end of the electric push rod 13, an ice-breaking blade 4 is rotatably connected inside the support frame 14, a second drive motor 15 is fixedly connected to the outside of the support frame 14, and the ice-breaking blade 4 is rotatably connected to the output end of the second drive motor 15. The support frame 14 is internally fixedly connected to a protective plate 16. The ice-breaking blade 4 is externally rotatably connected to the inside of the protective plate 16. The position of the ice-breaking blade 4 is precisely controlled by the electric push rod 13, and the drive motor 15 drives the ice-breaking blade 4 to rotate at high speed. This can effectively break up ice layers of different thicknesses on the rails. Even thicker ice layers can be cut and broken, greatly improving the efficiency of ice breaking and laying a good foundation for subsequent snow and ice removal work. The protective plate 16 effectively prevents ice splashes from damaging the equipment during the ice breaking process, reduces the maintenance cost and failure rate of the equipment, ensures that the snow and ice removal mechanism can operate stably for a long time, and improves the service life and reliability of the entire equipment, enabling it to better meet the needs of snow and ice removal tasks on railway tracks. A brine tank 7 is fixedly connected to the exterior of the snowplow body 1. A water pump 6 is fixedly connected inside the brine tank 7. A water pipe 5 is fixedly connected to the output end of the water pump 6. A nozzle 11 is fixedly connected inside the water pipe 5. Industrial brine is transported along the water pipe 5. Since the nozzle 11 is fixedly connected inside the water pipe 5, when the brine flows to the nozzle 11, it is sprayed onto the surface of the rails. After being sprayed onto the snow and ice on the rails, it can penetrate into their interior, lowering their melting point. This makes the snow and ice, which are originally difficult to melt in low-temperature environments, easier to melt into water, further improving the overall snow removal and de-icing effect. This helps the rails to return to a good state of being free of snow and ice more quickly, ensuring the safety of railway transportation. The water pipe 5 is externally fixedly connected to a fixing bracket 12. The fixing bracket 12 is fixedly connected to the outside of the snowplow body 1, and the water pipe 5 is externally fixedly connected to the fixing bracket 12. The fixing bracket 12 is in turn firmly fixedly connected to the outside of the snowplow body 1. This structural design can ensure that the water pipe 5 remains stable throughout the entire process of the snowplow operation and the water pump 6 pumping water and spraying salt water, and will not be displaced or disconnected due to factors such as vehicle shaking and vibration.

[0035] Reference Figure 1 , Figure 2 and Figure 5The snow removal assembly includes a drive motor 10, which is mounted on the exterior of the snow removal vehicle body 1. A blower 8 is fixedly connected to the output end of the drive motor 10, and a directional nozzle 21 is fixedly connected to the end of the blower 8. Starting the drive motor 10 causes the blower 8 to begin operating. The blower 8, through the high-speed rotation of its internal impeller, draws in and accelerates the compression of surrounding air, generating a powerful airflow. This airflow is then directed out through the directional nozzle 21, whose design allows the airflow to precisely act on the rail surface. This blows snow and ice fragments broken by the ice-breaking assembly away from the rails, dispersing them to areas further away on both sides of the rails, preventing them from returning to the rails and affecting railway operation. A connecting block 9 is fixedly connected to the outside of the snowplow body 1, and a baffle 2 is fixedly connected to the outside of the connecting block 9. The baffle 2 maintains a certain gap and angle with the rail. As the vehicle moves forward, the baffle 2 can push the snow accumulated inside the rail to both sides of the rail, realizing the initial dispersion and clearing of the snow, and avoiding a large amount of snow accumulating in the center of the rail and affecting the subsequent snow removal operation.

[0036] Reference Figure 4 and Figure 5 The snowplow body 1 is externally fixedly connected to a motor mount 17, and internally fixedly connected to a drive motor 18. A connecting rod 19 is fixedly connected to the output end of the drive motor 18, and a cleaning brush 20 is fixedly connected to the end of the connecting rod 19. When the drive motor 18 drives the connecting rod 19 to rotate, the cleaning brush 20 also rotates. During rotation, the bristles of the cleaning brush 20 contact the rail surface. Utilizing the friction between the bristles and the rail, as well as the elasticity of the bristles themselves, the brush cleans the rail surface, removing snow, ice, and other debris that remain after the snowplowing by the front baffle 2 and the blowing by the blower 8. This further improves the cleanliness of the rail surface, minimizing the amount of snow and ice residue on the rails and providing a more reliable guarantee for the safe operation of the railway. The external rotatable connection of the connecting rod 19 to the middle of the snowplow body 1 effectively improves the overall quality and effect of snow removal and de-icing work, ensuring that the railway can be restored to a good condition suitable for normal train operation as soon as possible.

[0037] Working principle: When the snowplow body 1 moves forward on the rails, the baffle 2 pushes the snow inside the rails to both sides. When it encounters ice on the rails, the electric push rod 13 is activated, pushing the ice-breaking blade 4 closer to the ice on the rails. Then, the drive motor 2 15 is activated, driving the ice-breaking blade 4 to rotate at high speed. The blade of the ice-breaking blade 4 cuts and breaks the ice into small pieces. The drive motor 1 10 starts, driving the blower 8 to work. The blower 8 generates a strong airflow, which is blown out through the directional port 21, blowing the snow and broken ice off the rails, achieving initial removal. At the same time, the drive motor 3 18 starts, driving the connecting rod 19 to rotate, causing the sweeping brush 20 to rotate and sweep the rail surface, further cleaning the remaining snow and ice fragments, ensuring that the snow on the rail surface is completely removed. The water pump 6 is started to extract industrial brine from the brine tank 7 and deliver it to the nozzle 11 through the water pipe 5. The nozzle 11 sprays the industrial brine onto the rails. Because the freezing point of industrial brine is lower than that of water, it makes snow or ice melt more easily, further improving the snow removal and de-icing effect. The water pipe 5 is fixed to the outside of the snowplow body 1 by the fixing bracket 12 to ensure that the brine can be sprayed stably onto the rails. In addition, the industrial brine can slow down the freezing rate.
