Description

Technical Field

[0001] This utility model relates to the field of railway track snow removal technology, and in particular to a railway track snow removal device. Background Technology

[0002] When railway tracks are covered with snow, it is often accompanied by severe weather such as low temperatures and strong winds. Some of the snow attached to the rails will freeze into ice, causing some of the snow to become ice that adheres to the surface of the rails and the inner and outer sides of the railway tracks, making it more difficult to remove. Therefore, snowplows are needed to remove snow from railway tracks. Snowplows are composed of wedge-shaped or V-shaped blades, suspension brackets, lifting cylinders, and independent walking wheels. They are pushed by manpower or motor vehicles. With the addition of a railway guidance system, they can travel on both roads and railways, pushing snow along the blade to one or both sides of the track. Due to their simple structure, high speed and efficiency, they are relatively universal.

[0003] Existing railway track snow removal devices, such as snowplows, can easily clog the discharge port when shoveling compacted or frozen snow, causing blockages inside the snowplow. Furthermore, because the discharge position is fixed, the direction and distance of snow throwing cannot be adjusted. When working alongside railways, if it is necessary to throw snow to different locations on both sides of the track, such as away from another track or a designated stacking point, the fixed channel cannot meet the flexible requirements. Snow may be thrown onto adjacent tracks that have just been cleared, or it may not be able to be thrown over high retaining walls, resulting in secondary cleaning. In view of this, we propose a railway track snow removal device. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] A railway track snow removal device, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a handcart 1, and a snowplow 2 is provided at the front end of the handcart 1. The snowplow 2 includes a bucket 201.

[0030] Centrifugal snow throwing component 3 is located on the back of bucket 201 and connected to the inside of bucket 201. It includes a transfer chamber 301, with a feed inlet 305 and a snow outlet 304 respectively opened on the top and one side of the transfer chamber 301.

[0031] An adjustable snow-throwing tube 4 is installed on the outer wall of the handcart 1. It includes a ring 401, a connecting frame 402 mounted on the outer wall of the ring 401, and is slidably connected to an adjusting component 403. A steel hoop 404 is fixed to the outer wall of the adjusting component 403. A flexible cylinder 405 is installed on one end of the inner wall of the steel hoop 404, and the other end of the flexible cylinder 405 is connected to a snow outlet 304 on one side of the transfer chamber 301. This application adds a centrifugal snow-throwing component 3 to the back of the snowplow 2, allowing the broken snow to enter the high-speed rotating centrifugal snow-throwing component 3 and be thrown out from the adjustable snow-throwing tube 4. This results in higher efficiency, less clogging, and because the adjustable snow-throwing tube 4 can adjust the position and pitch angle of the flexible cylinder 405's snow-throwing opening, it can roughly control the direction and distance of the snow-throwing, solving the problem of poor functionality in existing railway track snow removal devices such as snowplows.

[0032] Specifically, the width of the bucket 201 needs to be sufficient to enter the railway track, and the wheels of the handcart 1 also need to be sufficient to not overlap with the railway track, ensuring that it can be pushed smoothly and that the bucket 201 can penetrate deep into the railway track to shovel snow when pushed.

[0033] Specifically, the other end of the flexible cylinder 405 can be fixedly connected to the snow outlet 304 through steel hoops, flange connections, snap-fit ​​connections, etc., to ensure reliable connection and prevent snow leakage.

[0034] Preferably, the adjusting assembly 403 includes a sliding sleeve 4031 slidably connected to the outer wall of the ring 401. A damping plate 4032 is installed on the inner wall of the sliding sleeve 4031. The outer walls of the sliding sleeve 4031 and the damping plate 4032 are provided with threaded holes, and an adjusting bolt 4033 is threaded into the threaded holes. After loosening the adjusting bolt 4033, the sliding sleeve 4031 can be manually slid to change the horizontal orientation of the snow-throwing opening of the flexible cylinder 405, or the flexible cylinder 405 can be bent to change the pitch angle. After adjustment, the adjusting bolt 4033 is tightened so that its end abuts against the outer wall of the ring 401. The friction of the damping plate 4032 and the resistance of the adjusting bolt 4033 are used to lock it, thus achieving coarse control of the snow-throwing direction and distance.

[0035] Preferably, the snowplow 2 is provided with a feeding component 5, which includes a material box 501. The bottom of the material box 501 is connected to the discharge pipe 502 and the discharge pipe 502 is connected to the top inlet 305 of the transfer chamber 301.

[0036] Preferably, a spiral conveyor blade 503 is rotatably connected inside the discharge pipe 502, and the spiral conveyor blade 503 can be driven by a motor C504. The material box 501 can hold existing granular de-icing agent, and its bottom discharge pipe 502 is connected to the top of the centrifugal snow-throwing component 3. The spiral conveyor blade 503 is installed inside the pipe and is driven by a motor C504. It can quantitatively deliver the granular de-icing agent into the snow flow, so as to achieve preliminary mixing of snow and de-icing agent before throwing, enhance the melting effect, reduce the situation of snow clogging in the transfer chamber 301, and the spiral conveyor blade 503 can further prevent snow from entering the discharge pipe 502 and causing blockage of the discharge pipe 502. In order to reduce the damage of granular de-icing agent to the inner wall of the flexible cylinder 405, fine salt particles with finer particles are preferred.

[0037] Preferably, a spiral crushing bar 202 is rotatably connected to the inner wall of the bucket 201. The spiral crushing bar 202 can be driven by a motor A. The motor A 203 is located in the motor housing A 203. It can perform preliminary shearing and crushing of clumps or lightly compacted snow to prevent large snow clumps from blocking the subsequent passage.

[0038] Preferably, a centrifugal snow-throwing impeller 302 is rotatably connected to the inner wall of the transfer chamber 301. The centrifugal snow-throwing impeller 302 can be driven by a motor B, which is located in a motor housing B 303. The snow sent into the transfer chamber 301 is accelerated along the chamber wall by the high-speed rotating blades of the centrifugal snow-throwing impeller 302 under the action of strong centrifugal force, and finally thrown out from the snow outlet 304 at a high speed, reducing the chance of blockage and improving snow-throwing efficiency.

[0039] The working principle of the device in this application is as follows:

[0040] When in use, the operator pushes the handcart 1 to the starting point of the track to be cleaned and manually adjusts the adjustable snow thrower 4 according to the site conditions.

[0041] Loosen the adjusting bolt 4033 to allow the sliding sleeve 4031 and damping plate 4032 to slide on the ring 401, thereby driving the snow-throwing nozzle of the flexible cylinder 405 to rotate to the approximate direction. As the snow-throwing nozzle of the flexible cylinder 405 slides along the ring 401, its pitch angle is also adjusted synchronously. After the adjustment is completed, tighten the adjusting bolt 4033 and use the friction of the damping plate 4032 to lock the position.

[0042] The damping plate 4032 is an existing product and can be a rubber sheet, used to increase friction and allow the sliding sleeve 4031 to initially stop in the adjustment position.

[0043] The upper part of the material bin 501 is provided with a material bin inlet 6. If facing wet snow or thin ice, the feeding part 5 is required to open the material bin inlet 6, put an appropriate amount of granular de-icing agent into it, and then close the inlet.

[0044] Powered by an external power source, motors A and B are started sequentially via an external switch. The operator holds the handle of the handcart 1 and pushes it forward. The bucket 201 at the front end of the snowplow 2 cuts into the snow on the track and collects the snow into the bucket 201.

[0045] The electric motor A drives the spiral crusher 202 to rotate at high speed, which cuts and breaks up the shoveled snow clumps, making them easier to transport and throw.

[0046] After the pre-treated crushed snow enters the transfer chamber 301, the motor B drives the centrifugal snow-throwing impeller 302 to rotate at high speed. Under the action of strong centrifugal force, the snow is pressed tightly against the chamber wall and rotates faster. Finally, it is thrown out at high speed from the snow outlet 304 and enters the adjustable snow-throwing tube 4.

[0047] The centrifugal snow-throwing impeller 302 uses existing products, with blades designed to be curved backward relative to the direction of rotation, which is conducive to the smooth lifting and throwing of snow blocks. The blades also need to be treated for wear resistance.

[0048] The snow is guided by the flexible tube 405 and thrown out from the snow throwing port in a preset direction and angle, landing in the designated area outside the track.

[0049] During operation, if it is necessary to change the snow throwing point, such as to avoid obstacles or adjust the stacking position, the operator can stop moving at any time, loosen the adjusting bolt 4033 as described above, quickly adjust the direction of the snow outlet of the flexible cylinder 405, and then tighten it to continue the operation.

[0050] When needed, an external power supply is used to turn on motor C 504 via an external switch, driving the spiral conveyor blade 503 to rotate. The de-icing agent is transported from the material box 501 through the discharge pipe 502 to the inlet 305 of the transfer chamber 301, where it mixes with the snow flow and is thrown out together, enhancing the melting effect and reducing the situation of snow clogging in the transfer chamber 301. The spiral conveyor blade 503 can also further prevent snow from entering the discharge pipe 502 and causing blockage (motors A, B, and C 504 are all existing products and are all connected to an external power supply and an external switch).

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
