Abstract
Description
Technical Field
[0001] This application relates to the field of track maintenance equipment technology, and in particular to a snow removal and sand clearing device for tracks. Background Technology
[0002] The combined hazards of extreme snowfall and sandstorms in sandy areas (such as sand and snow compaction layers) pose an increasingly serious threat to the rail system, requiring solutions to multiple problems such as track compaction, ballast sand infiltration, and fastener aging.
[0003] Currently, railway snow removal mainly employs manual snow removal and heavy machinery. Manual snow removal often operates in the early morning, resulting in low efficiency (snow removal volume per person <2m). 3 While large snow removal equipment such as the GCX-1000 can improve efficiency, it suffers from drawbacks such as time-consuming loading and unloading of the upper and lower tracks and high purchase costs.
[0004] To address the problem of sand accumulation, existing solutions mostly employ passive protective measures such as isolation fences. However, in practical applications, periodic manual sand removal is still required, especially during seasons with frequent sandstorms. Traditional equipment is inefficient and dangerous in handling snow or sand accumulation. Utility Model Content
[0005] This application provides a snow and sand removal device for railway tracks, which can solve the technical problems of low efficiency and high danger in manual snow or sand removal in the prior art. The technical solution is as follows:
[0006] A snow and sand removal device for rails includes: a frame, a fuel engine, a bucket, a pusher wheel, a projectile impeller, and a handrail.
[0007] The vehicle frame includes a front wheel assembly and a rear wheel assembly at its bottom; a fuel engine mounted on the frame, having an output shaft connected to a drive shaft; a bucket located at the front end of the frame, having a left side plate, a right side plate, and an arc-shaped plate protruding towards the rear end of the frame between the left and right side plates. The left side plate, right side plate, and arc-shaped plate form a material-gathering cavity with an open front end. The middle of the arc-shaped plate has a projection cavity protruding towards the rear end of the frame. The cavity wall of the projection cavity is equipped with a discharge pipe communicating with the interior of the projection cavity. The discharge pipe is connected to a guide pipe at its end; the pusher wheel includes an axle, the two ends of which are rotatably connected to the left and right side plates respectively, the left half of the axle is connected to a first spiral blade, and the right half is connected to a second spiral blade, the first and second spiral blades rotating in opposite directions; the drive shaft meshes with the axle via a bevel gear set; the projectile impeller includes a bushing and projectile blades fixedly connected to the bushing, the projectile impeller being fixedly connected to the drive shaft via the bushing; and a handrail is fixedly connected to the rear end of the frame.
[0008] Optionally, the system also includes a sand-collecting shovel assembly, which comprises a left shovel and a right shovel, and a connecting rod connecting the left and right shovels. The left and right shovels are V-shaped. The left shovel includes a left upright plate and a left bottom plate located to the right of the left upright plate. The right shovel includes a right upright plate and a right bottom plate located to the left of the right upright plate. The distance between the front ends of the left and right upright plates is less than the spacing between the two rails of the track.
[0009] Optionally, the left half of the axle has two first helical blades, which together form a double-headed first helical blade; the right half of the axle has two second helical blades, which together form a double-headed second helical blade.
[0010] Optionally, each of the first helical blades has a plurality of first notches on its outer edge, and each of the second helical blades has a plurality of second notches on its outer edge.
[0011] Optionally, each of the first helical blades includes multiple left blade segments, and each of the second helical blades includes multiple right blade segments.
[0012] Optionally, the front wheel assembly includes two T-shaped track wheels arranged in pairs. Each T-shaped track wheel includes a column wheel and a flange connected to one end of the column wheel near the frame. The two column wheels are used to mount on two steel rails, and the flange is used to restrict the lateral movement of the column wheel.
[0013] Optionally, the rear wheel assembly includes a pair of triangular track wheels, each triangular track wheel including a drive wheel, two driven wheels, and a rubber track sleeved over the drive wheel and the two driven wheels, the drive wheel being drivenly connected to the drive shaft.
[0014] Optionally, the guide tubes are multiple, and the projection angles of the multiple guide tubes are not equal.
[0015] Optionally, the ejection cavity is cylindrical, and the centerline of the discharge pipe is tangent to the circle forming the ejection cavity.
[0016] The beneficial effects of the technical solutions provided in this application include at least the following:
[0017] A snow and sand removal device for rails includes: a frame, a fuel engine, a bucket, a pusher wheel, a throwing impeller, and a handle. Because the first helical blade on the left half of the axle and the second helical blade on the right half rotate in opposite directions, when the axle rotates, under the constraint of an arc-shaped plate, the first and second helical blades can break up snow or sand and push it towards the center or both ends of the bucket. When clearing snow or sand between two rails, the output shaft of the fuel engine transmits rotational motion to the drive shaft. The drive shaft drives the axle of the pusher wheel to rotate via a bevel gear set. The rotation direction of the first and second helical blades is set according to the rotation direction of the axle, enabling them to break up snow or sand and push it towards the center of the bucket during rotation. Since a throwing chamber is provided in the center of the bucket, and a throwing impeller is fixedly connected to the drive shaft, the drive shaft can simultaneously drive the throwing impeller to rotate, throwing the snow or sand in the throwing chamber through the discharge pipe. The snow and sand removal equipment for rails described in this application can break up the snow or sand between two rails and throw the snow or sand outside the rails, solving the technical problems of incomplete snow or sand removal and low efficiency in related technologies.

[0031] According to the embodiments of this application, refer to Figures 1 to 5 As shown, a snow removal and sand clearing device for rails includes: a frame 1, a fuel engine 10, a bucket 5, a pusher wheel 6, a projectile impeller 8, and a handrail 9.
[0032] Among them, reference Figure 1 As shown, a front wheel assembly 2 and a rear wheel assembly 3 are provided at the bottom of the frame 1. A fuel engine 10 is mounted on the frame 1 and has an output shaft, which is connected to a drive shaft 11.
[0033] In the embodiments of this application, "left" and "right" refer to the "left" and "right" determined with the observer as a reference when the observer's line of sight is the same as the direction of travel of the snow removal and sand clearing equipment. "Front" and "back" refer to the "front" and "back" when the observer's line of sight is the same as the direction of travel of the snow removal and sand clearing equipment. The direction of sight is the same as the observer's line of sight.
[0034] refer to Figure 2 and Figure 3 As shown, the bucket 5 is located at the front end of the frame 1 and has a left side plate 501, a right side plate 502, and an arc-shaped plate 503 that protrudes towards the rear end of the frame 1 between the left side plate 501 and the right side plate 502. The left side plate 501, the right side plate 502 and the arc-shaped plate 503 form a material gathering cavity with an opening at the front end. The middle part of the arc-shaped plate 503 has a throwing cavity 504 that protrudes towards the rear end of the frame 1. The cavity wall of the throwing cavity 504 is provided with a discharge pipe 505 that communicates with the inside of the throwing cavity 504. The end of the discharge pipe 505 is connected to a guide pipe 506.
[0035] refer to Figure 4 As shown, the pusher wheel 6 includes a wheel axle 601, with both ends of the wheel axle 601 rotatably connected to the left side plate 501 and the right side plate 502, respectively. The left half of the wheel axle 601 is connected to a first spiral blade 602, and the right half is connected to a second spiral blade 603. The first spiral blade 602 and the second spiral blade 603 rotate in opposite directions. The drive shaft 11 meshes with the wheel axle 601 through a bevel gear set 7.
[0036] refer to Figure 6 As shown, the projectile impeller 8 includes a bushing and projectile blades 801 fixedly connected to the bushing. The projectile impeller 8 is fixedly connected to the drive shaft 11 via the bushing. (Reference) Figure 1 As shown, the armrest 9 is fixedly connected to the rear end of the frame 1.
[0037] In the above embodiment, since the first spiral blade 602 on the left half of the wheel axle 601 and the second spiral blade 603 on the right half rotate in opposite directions, when the wheel axle 601 rotates, under the constraint of the arc plate 503, the first spiral blade 602 and the second spiral blade 603 can break up the snow or sand and push it to the middle of the bucket 5 or to both ends of the bucket 5. When clearing snow or sand between two rails, the output shaft of the fuel engine 10 transmits rotational motion to the drive shaft 11. The drive shaft 11 drives the axle 601 of the pusher wheel 6 to rotate via the bevel gear set 7. The rotation direction of the first spiral blade 602 and the second spiral blade 603 is set according to the rotation direction of the axle 601, so that the first spiral blade 602 and the second spiral blade 603 crush the snow or sand and push it towards the center of the bucket 5 when rotating. Since the center of the bucket 5 is provided with a throwing chamber 504, and a throwing wheel is fixedly connected to the drive shaft 11, the drive shaft 11 can simultaneously drive the throwing wheel to rotate, throwing the snow or sand in the throwing chamber 504 out through the discharge pipe 505. The snow and sand removal equipment for rails of this application can crush the snow or sand between two rails and throw the snow or sand outside the rails, solving the technical problems of incomplete snow or sand removal and low efficiency in related technologies.
[0038] refer to Figure 4 As shown, if the drive shaft 11 rotates counterclockwise and the wheel axle 601 rotates forward, then the first helical blade on the left half of the wheel axle 601 rotates to the right and the second helical blade on the right half of the wheel axle 601 rotates to the left. Under the constraint of the arc plate 503 of the bucket 5, the rotation of the first and second helical blades can push the snow or sand towards the middle of the bucket 5.
[0039] According to the embodiments of this application, refer to Figure 1 and Figure 5 As shown, the snow and sand removal equipment also includes a sand-collecting shovel assembly 4, which includes a left shovel 401 and a right shovel 402, as well as a connecting rod 403 connecting the left shovel 401 and the right shovel 402.

The right shovel 402 includes a right upright plate 4021 and a right bottom plate 4022 located to the left of the right upright plate 4021. The distance between the front end of the left upright plate 4011 and the front end of the right upright plate 4021 is less than the distance between the two rails of the track. With this design, snow or sand can be initially collected, thus facilitating the collection of snow or sand by the pusher wheel 6.
[0040] According to the embodiments of this application, refer to Figure 4As shown, in order to improve the working efficiency of the pusher wheel 6, the left half of the wheel shaft 601 has two first spiral blades 602, which together form a double-headed first spiral blade 602; the right half of the wheel shaft 601 has two second spiral blades 603, which together form a double-headed second spiral blade 603.

This improves the crushing efficiency of the first spiral blades 602 and the second spiral blades 603, making it easier to push snow or sand.
[0042] According to the embodiments of this application, refer to Figure 5 As shown, each first spiral blade 602 includes multiple left blade segments, and each second spiral blade 603 includes multiple right blade segments. Setting the first spiral blade 602 as multiple left blade segments and the second spiral blade 603 as multiple right-left blade segments facilitates manufacturing and increases the cutting edge of the spiral blades, thereby improving crushing efficiency.

In this case, a battery for powering the triangular track wheels can be installed on the frame 1, or a generator for powering the triangular track wheels can be installed on the frame 1, the generator being driven by a diesel engine.
[0045] According to the embodiments of this application, refer to Figure 2As shown, there are multiple guide tubes 506, and the projection angles of the multiple guide tubes 506 are not equal. For example, the guide tube 506 includes a connecting section connected to the discharge tube 505, and a projection section at a certain angle to the connecting section. The angle between the projection section and the connecting section can be 90°, 120°, 135°, etc.
[0046] According to an embodiment of this application, the ejection cavity 504 is cylindrical, and the centerline of the discharge pipe 505 is tangent to the circle forming the ejection cavity 504.
[0047] The implementation principle of this application is explained below with reference to specific operational steps:
[0048] The first step is to move the snow removal and sand clearing equipment used for the tracks to the middle of the two rails and then install the two T-shaped track wheels on the two rails respectively.
[0049] The second step is to start the fuel engine 10, and the drive shaft 11 rotates counterclockwise, which drives the wheel axle 601 of the pusher wheel 6 to roll forward and drive the ejector impeller 8 to rotate counterclockwise, while driving the triangular track wheel forward.
[0050] The third step involves the pusher wheel 6 breaking up the snow or sand and pushing it to the middle of the bucket 5.
