Snow removing and pushing all-in-one machine with barrier avoidance function

Abstract

The application discloses a barrier-avoiding snow pushing and stirring integrated machine for highway snow removal, which comprises a wave-shaped wheel, an elastic damping mechanism and a snow pushing mechanism. The wave-shaped wheel can be in contact with a highway guardrail. The snow pushing frame and the elastic damping mechanism are rotationally connected. The snow pushing frame can swing in the direction horizontal to the guardrail plate through the elastic damping mechanism. The elastic damping mechanism can push the snow pushing frame to the direction of the guardrail plate. When the A-shaped frame two slides on the mounting frame body, when the angle of the A-shaped frame one and the A-shaped frame two is fixed by the angle limiting assembly, the snow pushing frame and the mounting frame body are relatively fixed. The snow pushing mechanism comprises a barrier-avoiding snow pushing assembly. When the snow pushing mechanism rotates to the side close to the stirring frame, the barrier-avoiding snow pushing assembly is arranged between the stirring frame and the spiral stirring device. The application can avoid rigid collision with the guardrail when snow removal is performed under the highway guardrail, and meanwhile, sufficient snow removal can be ensured for the dead angle position.

Description

Technical Field

[0001] This invention relates to the field of highway snow removal equipment technology, and in particular to an obstacle-avoiding push-stirring integrated machine for highway snow removal. Background Technology

[0002] During winter snowfall, snow accumulation zones easily form on the inner and outer sides of W-shaped guardrails on highways and main roads. At the same time, due to the obstruction effect of the guardrails and posts, traditional snowplows and snow sweeping devices are difficult to clear the snow accumulation zones under the guardrails and the blind spots on the sides of the posts. Usually, manual work is required after the snowplows have passed. This process is inefficient and poses significant safety hazards to the cleaning personnel.

[0003] To address the specific needs of snow removal operations in the blind spots below guardrails, a snowplow with integrated pushing and stirring mechanism that can avoid obstacles has been developed. The snowplow is mounted on a vehicle, and as the vehicle travels along the guardrail, it pushes the snow inside the guardrail to the outside using snowplows. The spiral auger located on the outside of the guardrail then throws the snow onto the outside of the shoulder, thus completing the snow removal work on both the inside and outside of the guardrail in one go, improving snow removal efficiency.

[0004] Existing integrated snowplows and augers have snowplows that can reach under guardrails to shovel snow. The snowplows automatically avoid posts and then return to their original position to scrape the snow between the posts. However, because the snowplows and augers are connected by a rigid frame, the augers are moved to the other side of the guardrail by rotating the support frame. The positioning of the snowplows and augers relative to the guardrails is controlled by the driver's sense of touch. The support frame and snow removal device are located on the side of the vehicle, creating a natural blind spot. During operation, collisions between the snowplows, auger blades, and posts are very likely to occur. Impact loads can cause direct deformation and breakage. Although the snowplows have obstacle avoidance capabilities, if the contact point with the posts is not positioned correctly, impacts can still deform the snowplows.

[0005] Meanwhile, when vehicles are moving, the guardrails bend and shift slightly with the road, making it difficult for drivers to adjust the distance between the snowplow and the guardrail. Excessive distance makes it difficult to maintain proper working clearance, while insufficient distance significantly increases the risk of collision. Aligning the guardrail with the support frame is also challenging, resulting in inconsistent snow removal. Existing obstacle avoidance equipment only addresses uneven ground and protruding rocks by allowing longitudinal movement to avoid them, failing to handle lateral collisions or provide early warning. Therefore, providing a snow removal obstacle avoidance integrated snowplow and shovel machine for highways is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One objective of this invention is to provide an obstacle-avoiding push-stirring integrated machine for highway snow removal. This invention can avoid rigid collisions with the guardrail when clearing snow under the highway guardrail, while ensuring sufficient snow removal in blind spots.

[0007] According to an embodiment of the present invention, a road snow removal obstacle avoidance type snowplow and auger integrated machine includes a mounting frame, a snowplow frame, an auger frame, and a spiral auger device. The mounting frame is detachably connected to a vehicle. The snowplow frame is connected to the mounting frame. The spiral auger device is mounted on the auger frame. The auger frame is rotatably connected to the snowplow frame. During snow removal, the road guardrail is positioned between the snowplow frame and the spiral auger device. The machine also includes a wave-shaped wheel, an elastic damping mechanism, and a snowplow mechanism. The wave-shaped wheel is rotatably connected to the snowplow frame on the side near the auger frame. The wave-shaped wheel can contact the road guardrail. The wave-shaped wheel has protrusions and indentations that cooperate with the guardrail. When the vehicle is moving, the wave-shaped wheel is in contact with the guardrail to maintain the relative position between the snowplow assembly, the spiral auger device, and the guardrail. The elastic damping mechanism is disposed on the mounting frame. The snowplow frame and the elastic damping mechanism rotate... The snowplow frame is dynamically connected and can swing horizontally perpendicular to the guardrail via the elastic damping mechanism. The elastic damping mechanism can also push the snowplow frame towards the guardrail. The elastic damping mechanism includes an A-frame one, an A-frame two, and an angle-limiting component. The A-frame one is rotatably connected to the mounting frame, and the A-frame two is slidably connected to the mounting frame. The A-frame two slides on the mounting frame, allowing the A-frame one and A-frame two to rotate. When the angle between the A-frame one and A-frame two is fixed by the angle-limiting component, the snowplow frame and the mounting frame are relatively fixed. The snowplow mechanism is rotatably connected to the snowplow frame and includes an obstacle-avoiding snowplow component. When the snowplow mechanism rotates to a side closer to the auger frame, the obstacle-avoiding snowplow component is positioned between the auger frame and the spiral auger device.

[0008] Drive cylinder three is rotatably connected to the snowplow frame. The output end of drive cylinder three is rotatably connected to the auger frame. Drive cylinder three passes between A-frame one and the mounting frame. The output end of drive cylinder three can drive the auger frame to rotate.

[0009] The elastic damping mechanism also includes a horizontal track, a positioning platform, and a drive cylinder. The horizontal track is fixedly connected to the mounting frame, and the positioning platform is slidably connected to the horizontal track. The drive cylinder is installed on the mounting frame, and the output end of the drive cylinder is connected to the positioning platform. The A-frame is rotatably connected to the positioning platform. When clearing snow, the A-frame and the A-frame remain parallel to each other.

[0010] A shock-absorbing device is rotatably connected to the positioning platform, and the shock-absorbing device is rotatably connected to the A-frame 2. A pressure detection component is installed on the shock-absorbing device. The contact between the wave-shaped wheel and the guardrail prevents the snow-push mechanism from getting too close to the guardrail. The distance between the vehicle and the guardrail directly affects the pushing force of the shock-absorbing device on the A-frame 2. The pressure detection mechanism can then determine the distance between the vehicle and the guardrail, allowing the driver to adjust the driving direction based on the pressure reading.

[0011] The snow-pushing mechanism also includes an incline platform, a first connecting rod, a second drive cylinder, and a snow-pushing plate. The incline platform is mounted on the snow-pushing frame, and multiple first connecting rods are rotatably connected to the incline platform. The second drive cylinder is rotatably mounted on the snow-pushing frame, and the output end of the second drive cylinder is rotatably connected to one of the first connecting rods. The snow-pushing plate is rotatably connected to multiple first connecting rods. The obstacle-avoiding snow-pushing assembly is located on the side of the snow-pushing plate near the spiral auger device.

[0012] The obstacle avoidance and snow pushing assembly includes a second link, an obstacle avoidance snow plate, and a spring cylinder. Multiple second links are rotatably connected to the snow pushing plate, and the ends of multiple second links away from the snow pushing plate are rotatably connected to the obstacle avoidance snow plate. The spring cylinder is rotatably mounted on the snow pushing plate, and the output end of the spring cylinder is rotatably connected to one of the second links. The obstacle avoidance snow plate can rotate towards the snow pushing frame via the second link.

[0013] The obstacle avoidance snowboard and the snowplow are inclined toward the auger device. Multiple extrusion wheels are arranged on the side of the obstacle avoidance snowboard away from the snowplow frame, and these extrusion wheels can contact the pillar or obstacle. Traditional snowplows avoid pillars by rotating as a whole when in contact with them, but this rotation reduces the snow-pushing area and creates a large blind spot. The extrusion wheels, upon contacting the pillar, push the obstacle avoidance snowboard to rotate at an angle parallel to the snowplow, thus avoiding the obstacle without affecting the snow-pushing area. Furthermore, the blind spot is smaller when the obstacle avoidance snowboard slides along the pillar.

[0014] The snowplow is located near the obstacle avoidance snowboard, and a snow blowing pipe is provided on the side near the snowplow frame. The air outlet of the snow blowing pipe faces the obstacle avoidance snowboard. The snow blowing pipe is connected to the air supply device on the vehicle. When the obstacle avoidance snowboard rotates between the snowplow and the snowplow frame, the snow blowing pipe blows air onto the ground.

[0015] The tilting platform is vertically slidably connected to the snowplow frame, and the output end of the second drive cylinder is slidably and rotatably connected to the first connecting rod. When the first and second A-frames are parallel, the snowplow frame can sway. However, when the snowplow frame sways, it will also make a small range of longitudinal movement when moving horizontally. When the snowplow frame and the auger frame sway with the guardrail, the distance between the snowplow frame and the ground will also change. The longitudinal sliding of the tilting platform can prevent the gap between the snowplow blade and the ground from being too large, which would affect the snow removal effect, and can also prevent the snowplow blade from being squeezed against the ground and damaged.

[0016] The angle limiting assembly includes a limiting plate one and a limiting plate two. The limiting plate one is fixedly connected to the A-frame one. A stop bar one is provided on the mounting frame at a position corresponding to the limiting plate one. The limiting plate two is fixedly connected to the A-frame two. A stop bar two is provided on the positioning platform at a position corresponding to the limiting plate two. When the A-frame one rotates to the point where the limiting plate one contacts the stop bar one, and the A-frame two rotates to the point where the limiting plate two contacts the stop bar two, the A-frame one and the A-frame two are relatively fixed.

[0017] The beneficial effects of this invention are:

[0018] This invention, by setting up A-frame 1 and A-frame 2, when A-frame 1 and A-frame 2 are parallel, A-frame 1, A-frame 2, the mounting frame and the snowplow frame form a parallelogram. The snowplow frame can sway, and at the same time, the shock-absorbing device pushes A-frame 2, so that the wave wheel is in contact with the guardrail. The distance between the vehicle and the guardrail changes at any time when the vehicle is moving, so the distance between the mounting frame and the snowplow frame also changes. The shock-absorbing device buffers and pushes, keeping the distance between the snowplow mechanism and the guardrail relatively fixed. When the vehicle is moving, it will not cause hard collisions to the mounting frame, snowplow frame and auger frame, reducing the damage rate.

[0019] By setting up an obstacle avoidance snow-push assembly, the obstacle avoidance snow plate can rotate parallel to the column when it comes into contact with the column. It can rotate along the surface of the column and clear the snow near the column. In traditional snowplows, the snow-push plate rotates as a whole. This application sets up only a smaller obstacle avoidance snow plate to rotate, which can avoid the reduction of the snow-push area when the snow-push plate rotates as a whole. At the same time, the rotation method of the whole snow-push plate makes it easy for the snow-push plate to come into contact with the wave wheel, making it difficult to effectively avoid obstacles.

[0038] Example 1

[0039] A road snow removal obstacle avoidance push-stirring integrated machine, reference Figures 1-2 The system includes a mounting frame 100, a snowplow frame 101, an auger frame 103, and a spiral auger device 104. The mounting frame 100 is detachably connected to the vehicle. The snowplow frame 101 is connected to the mounting frame 100. The spiral auger device 104 is mounted on the auger frame 103. The auger frame 103 is rotatably connected to the snowplow frame 101. During snow removal, the highway guardrail is positioned between the snowplow frame 101 and the spiral auger device 104. The system also includes a wave-shaped wheel 200, an elastic damping mechanism, and a snowplowing mechanism. The wave-shaped wheel 200 is rotatably connected to the snowplow frame 101 on the side near the auger frame 103. The wave-shaped wheel 200 can contact the highway guardrail. (Reference) Figure 8 The wave-shaped wheel 200 has protrusions and recesses that mate with the guardrail. When the vehicle is moving, the wave-shaped wheel 200 fits against the guardrail to maintain the relative position between the snowplow assembly, the auger device 104, and the guardrail. An elastic damping mechanism is mounted on the mounting frame 100. The snowplow frame 101 and the elastic damping mechanism are rotatably connected. The snowplow frame 101 can swing horizontally perpendicular to the guardrail via the elastic damping mechanism, and the elastic damping mechanism can push the snowplow frame 101 towards the guardrail. (Reference) Figures 3-4 The elastic damping mechanism includes A-frame 1 201, A-frame 2 202, and a limiting component. A-frame 1 201 is rotatably connected to the mounting frame 100, and A-frame 2 202 is slidably connected to the mounting frame 100. (Reference) Figures 9-12When A-frame 202 slides on the mounting frame 100, it allows A-frame 1 201 and A-frame 202 to rotate. When the angle between A-frame 1 201 and A-frame 202 is fixed by the angle limiting component, the snowplow frame 101 and the mounting frame 100 are relatively fixed, and the snowplow mechanism is rotatably connected to the snowplow frame 101. (Reference) Figures 3-8 The snow-pushing mechanism includes an obstacle-avoiding snow-pushing component. When the snow-pushing mechanism rotates to the side close to the auger frame 103, the obstacle-avoiding snow-pushing component is positioned between the auger frame 103 and the spiral auger device 104. After the obstacle-avoiding snow-pushing component contacts the column, it avoids obstacles. The snow-pushing mechanism does not rotate as a whole, thus maintaining the snow-pushing area.

[0040] A drive cylinder 102 is rotatably connected to the snowplow frame 101, and the output end of the drive cylinder 102 is rotatably connected to the auger frame 103. (Reference) Figures 3-5 Drive cylinder 3 102 passes between A-frame 1 201 and the mounting frame 100. The output end of drive cylinder 3 102 can drive the auger frame 103 to rotate. By setting the structure of A-frame 1 201 and A-frame 2 202, drive cylinder 3 102 passes through the gap of A-frame 1 201, thereby making fuller use of the space. A-frame 1 201 and A-frame 2 202 are set in the middle of snowplow frame 101 to improve the force balance of snowplow frame 101 and auger frame 103 as much as possible, and to prevent snowplow frame 101 and auger frame 103 from tilting away from the mounting frame 100.

[0041] refer to Figure 4 The elastic damping mechanism also includes a horizontal track 203, a positioning platform 204, and a drive cylinder 205. The horizontal track 203 is fixedly connected to the mounting frame 100, and the positioning platform 204 is slidably connected to the horizontal track 203. The drive cylinder 205 is mounted on the mounting frame 100, and its output end is connected to the positioning platform 204. The A-frame 2 is rotatably connected to the positioning platform 204. During snow removal, the A-frame 1 and A-frame 2 remain parallel to each other. During snow removal, the drive cylinder 205 drives the positioning platform 204 to slide, so that the distance between the connection point of the A-frame 1 and the mounting frame 100, and the rotatable connection point of the A-frame 2 and the positioning platform 204, is the same as the distance between the connection points of the A-frame 1 and A-frame 2 on the snowplow frame 101, thus forming a parallelogram. The snowplow frame 101 can sway on the mounting frame 100. Figures 9-12After the snow removal is completed, the positioning platform 204 slides, and the distance between the connection positions of A-frame 1 201 and A-frame 2 202 on one side of the mounting frame 100 increases, changing the parallelogram structure. At this time, it is difficult to maintain balance between the mounting frame 100 and the snowplow frame 101. The snowplow frame 101 tilts under the weight of the auger frame 103, and at the same time, it drives A-frame 1 201 and A-frame 2 202 to rotate. When the positioning platform 204 slides to the position where the angle of A-frame 1 201 and A-frame 2 202 is limited by the angle limiting component, the relative angle of A-frame 1 201 and A-frame 2 202 is fixed and cannot rotate. At this time, the snowplow frame 101 is fixed and cannot shake.

[0042] A shock-absorbing device 206 is rotatably connected to the positioning platform 204, for reference. Figures 3-4 The shock absorber 206 is rotatably connected to the A-frame 2. The shock absorber 206 is equipped with a pressure detection component 207. When the vehicle approaches the guardrail, the shock absorber 206 is compressed and shortened, increasing the pressure. At the same time, when the shock absorber 206 is compressed, the wave wheel 200 is in contact with the guardrail, buffering the distance changes caused by the vehicle's movement. Through the contact between the wave wheel 200 and the guardrail, the snow-push mechanism will not get too close to the guardrail. The distance between the vehicle and the guardrail directly affects the pushing force of the shock absorber 206 on the A-frame 2. The pressure detection component can then determine the distance between the vehicle and the guardrail. The driver can adjust the driving direction by judging the pressure. When the pressure detected by the pressure detection component 207 is too high, the vehicle can be turned away from the guardrail, and vice versa. The driving direction can be adjusted by the magnitude of the pressure reading.

[0043] refer to Figures 10-12 The angle limiting assembly includes a first limiting plate 400 and a second limiting plate 402. The first limiting plate 400 is fixedly connected to the first A-frame 201. A first stop bar 401 is provided on the mounting frame 100 at a position corresponding to the first limiting plate 400. The second limiting plate 402 is fixedly connected to the second A-frame 202. A second stop bar 403 is provided on the positioning platform 204 at a position corresponding to the second limiting plate 402. When the first A-frame 201 rotates until the first limiting plate 400 contacts the first stop bar 401, and the second A-frame 202 rotates until the second limiting plate 402 contacts the second stop bar 403, the first A-frame 201 and the second A-frame 202 are relatively fixed. The first limiting plate 400 is located on the side of the first A-frame 201 closest to the second A-frame 202. (Reference) Figures 11-12When A-frame 1 201 rotates to the side close to A-frame 2 202, the limiting plate 1 400 contacts the stop bar 1 401. At this time, A-frame 1 201 cannot continue to rotate towards A-frame 2 202. The limiting plate 2 402 is set on the side of A-frame 2 202 close to A-frame 1 201. As the positioning platform 204 slides away from A-frame 1 201, the angle between A-frame 2 202 and the positioning platform 204 gradually decreases. When the limiting plate 2 402 contacts the stop bar 2 403, A-frame 2 202 cannot rotate. When neither A-frame 1 201 nor A-frame 2 202 can rotate, the snowplow 303 cannot move. At this time, the positioning platform 204 stops sliding, thus completing the positioning of the snowplow frame 101.

[0044] refer to Figures 5-8 The snow-pushing mechanism also includes an incline platform 300, a first connecting rod 301, a second driving cylinder 302, and a snow-pushing plate 303. The incline platform 300 is mounted on the snow-pushing frame 101, and multiple first connecting rods 301 are rotatably connected to the incline platform 300. In this application, two first connecting rods 301 are set to form a parallelogram, so that the snow-pushing plate 303 remains parallel when it rotates. The second driving cylinder 302 is rotatably mounted on the snow-pushing frame 101, and the output end of the second driving cylinder 302 is rotatably connected to one of the first connecting rods 301. The snow-pushing plate 303 is rotatably connected to multiple first connecting rods 301. The obstacle-avoiding snow-pushing component is set on the side of the snow-pushing plate 303 near the spiral auger device 104. When clearing snow, the snow-pushing plate 303 remains stationary, and only the obstacle-avoiding snow-pushing component avoids the column.

[0045] The obstacle avoidance and snow pushing assembly includes a second linkage 304, an obstacle avoidance snow plate 305, and a spring cylinder 306. Multiple second linkages 304 are rotatably connected to the snow pushing plate 303. (See reference...) Figures 5-8 Two connecting rods 304 are rotatably connected to a snow avoidance plate 305 at the ends away from the snowplow 303. A spring cylinder 306 is rotatably mounted on the snowplow 303. The output end of the spring cylinder 306 is rotatably connected to one of the connecting rods 304. The snow avoidance plate 305 can rotate towards the snowplow frame 101 via the connecting rods 304. When the snow avoidance plate 305 slides with the snowplow 303 and encounters an obstacle, it is pushed in the direction of the wave wheel 200. At this time, the snow avoidance plate 305 will rotate while maintaining parallelism and slide towards the snowplow 303. When the snow avoidance plate 305 moves to the side of the obstacle that is close to the snowplow 303, it can pass by the side of the obstacle, thus clearing the snow around the obstacle and avoiding it at the same time.

[0046] refer to Figure 3 and Figure 5The obstacle avoidance snowboard 305 and the snowplow 303 are inclined toward the spiral auger device 104. Multiple extrusion wheels 307 are provided on the side of the obstacle avoidance snowboard 305 away from the snowplow frame 101. The extrusion wheels 307 can contact the column or obstacle. The traditional snowplow 303 avoids the column by rotating as a whole when it contacts the column. However, the overall rotation of the snowplow 303 will reduce the snowplowing area and the blind spot range is also large. After the extrusion wheels 307 contact the column, they push the obstacle avoidance snowboard 305 to rotate at an angle parallel to the snowplow 303. This only avoids the obstacle and does not affect the snowplowing area. At the same time, the blind spot range is small when the obstacle avoidance snowboard 305 slides along the column.

[0047] A snow blower 308 is located on the side of the snowplow 303 near the obstacle avoidance snowplow 305 and close to the snowplow frame 101. (See reference) Figures 6-7 The air outlet of the snow blower pipe 308 faces the snow avoidance plate 305. The snow blower pipe 308 is connected to the air supply device on the vehicle. When the snow avoidance plate 305 rotates between the snowplow 303 and the snowplow frame 101, the snow blower pipe 308 blows air onto the ground. As the snow avoidance plate 305 rotates, it passes by the side of the pillar. When the snow avoidance plate 305 scrapes the side of the pillar, there are inevitably blind spots. The air supply through the snow blower pipe 308 can disperse the snow in the blind spots. It can also disperse snow that cannot be transported to the auger device 104, preventing it from accumulating and freezing. During normal snow removal, the snow blower pipe 308 can also maintain the blowing state to improve the secondary cleaning of snow that may not have been completely cleared.

[0048] The tilting platform 300 is vertically slidably connected to the snowplow frame 101. The output end of the second drive cylinder 302 is slidably and rotatably connected to the first connecting rod 301. When the first A-frame 201 and the second A-frame 202 are parallel, the snowplow frame 101 can sway. However, when the snowplow frame 101 sways, it will also move longitudinally in a small range when moving horizontally. When the snowplow frame 101 and the auger frame 103 sway with the guardrail, the distance between the snowplow frame 101 and the ground will also change. Setting the tilting platform 300 to slide longitudinally can avoid the gap between the snowplow plate 303 and the ground being too large, which would affect the snow removal effect. It can also avoid the snowplow plate 303 squeezing the ground and causing damage to the snowplow plate 303.

[0049] In this embodiment, a wave-shaped wheel 200 is installed on the snowplow frame 101 to contact the guardrail. The contact between the wave-shaped wheel 200 and the guardrail ensures the relative distance between the snowplow blade 303, the spiral auger device 104 and the guardrail. At the same time, through the elastic damping mechanism connected between the mounting frame 100 and the snowplow frame 101, when the distance between the vehicle and the guardrail changes during vehicle movement, the snowplow frame 101 shakes on the mounting frame 100 through A-frame 1 201 and A-frame 2 202, thereby buffering the deviation of the vehicle's driving direction and avoiding rigid impact between the snowplow frame 101 and the guardrail. Meanwhile, by maintaining the contact between the wave-shaped wheel 200 and the guardrail, the distance between the snowplow blade 303 and the guardrail will not be too far or too close during snow removal.

[0050] Working Principle: When A-frame 1 201 and A-frame 2 202 are parallel, they form two sides of a parallelogram, allowing the snowplow frame 101 to rotate on the mounting frame 100. Simultaneously, the damping device 206 pushes A-frame 202, giving the snowplow frame 101 a force towards the auger frame 103. This force causes the wave-shaped wheel 200 to contact the guardrail. When the wave-shaped wheel 200 contacts the guardrail, the distance between the snowplow blade 303 and the guardrail remains relatively fixed. When the distance between the vehicle and the guardrail changes, the rotation of A-frame 1 201 and A-frame 2 202 buffers the horizontal distance changes, ensuring that the contact between the wave-shaped wheel 200 and the guardrail is not affected. This avoids damage to the snow removal device caused by rigid contact and ensures efficient snow removal of the area below the guardrail. Furthermore, the tilting platform 300 vertically tilts the snowplow frame 101... The sliding mechanism and the movable shovel plate below the auger device 104 can counteract the longitudinal displacement of the snowplow frame 101 when A-frame 1 201 and A-frame 2 202 rotate. After snow removal is completed, the output end of the drive cylinder 1 205 extends to push the positioning platform 204 to slide on the horizontal track 203. A-frame 2 202 drives the snowplow frame 101 to move away from the auger frame 103, and A-frame 1 201 rotates to be close to A-frame 2 202. In the direction of 202, the mounting frame 100, A-frame 1 201, snowplow frame 101 and A-frame 2 202 form an irregular quadrilateral. When the limiting plate 1 400 contacts the stop bar 1 401 and the limiting plate 2 402 contacts the stop bar 2 403, A-frame 1 201 and A-frame 2 202 cannot rotate, and the snowplow frame 101 is also difficult to rotate, thus achieving the effect of fixing the snowplow frame 101. The output end of the drive cylinder 1 205 also stops moving.

[0051] Example 2

[0052] The shock absorber 206 can be replaced with an axial pushing device, such as a drive cylinder, and a pressure sensor can be installed at the connection position between the wave wheel 200 and the snowplow frame 101, or a distance sensor can be installed on the snowplow frame 101 near the guardrail to detect the distance between the snowplow frame and the guardrail. When the distance between the snowplow frame and the guardrail is detected to be too small or too large, the drive cylinder can be adjusted simultaneously to push the A-frame 202 to rotate, maintaining the contact between the wave wheel 200 and the guardrail. When the distance between the vehicle and the guardrail changes while the vehicle is moving, the distance between the snowplow frame 101 and the guardrail can be actively adjusted in real time through a closed-loop operation of detecting the distance change - pushing the A-frame 202 to rotate - the snowplow 303 to generate horizontal displacement - adjusting the distance to a suitable position. The range within which the drive cylinder can push the A-frame 202 to rotate while the driver is driving the vehicle is the allowable range of distance changes between the vehicle and the guardrail while the vehicle is moving.
