Description

Technical Field

[0001] This utility model relates to the field of road clearing technology, and more specifically, to a snow removal device for highway construction. Background Technology

[0002] In northern regions and high-altitude areas where snowfall is frequent in winter, snowfall becomes a major obstacle to construction. Snow not only covers the construction site, affecting the visibility of construction workers on the construction area and signs, but it can also freeze rapidly in low temperatures, making the road surface slippery. Therefore, it is necessary to install a snow removal device for highway construction. This device must have a strong snow removal capacity, be able to quickly remove large areas of snow, adapt to complex terrain, and flexibly move between various obstacles on the construction site, thereby creating a safe and efficient working environment for highway construction and ensuring the smooth progress of the project.

[0003] Existing highway construction snow removal equipment features a rotating drum with multiple sets of optimized blades. Retractable snow deflectors are installed on both sides of the rotating drum. Power is distributed from the engine to drive its high-speed rotation. The blades cut into the snow layer and push the snow into the equipment. Then, the power drives the spiral conveyor to rotate, and the spiral blades transport the snow to one side along a specific channel. Finally, the snow reaches the high-speed rotating snow-throwing impeller, which uses centrifugal force to throw the snow to one side of the road, completing the snow removal process.

[0004] However, during highway construction, the road width varies at different construction stages. When the roadbed is widened, the width of some sections narrows, while the width of some sections increases after the road base is laid. The fixed snow removal width of traditional snow removal devices cannot flexibly match these changes, affecting the surrounding construction. Secondly, the snow baffles of traditional snow removal devices have a fixed length and cannot be folded, resulting in them occupying too much space in narrow sections or when not in operation, affecting the transportation and storage of equipment. Utility Model Content

[0005] This utility model provides a snow removal device for highway construction, which solves the problem mentioned in the background art that the road surface width varies during the highway construction stage, and traditional snow removal devices have fixed snow removal widths and non-extendable and non-foldable snow barriers, which affect the surrounding construction and cause inconvenience in equipment transportation and storage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a snow removal device for highway construction, comprising a vehicle body, a snow cover at the front end of the vehicle body, a rotatable impeller rod inside the snow cover, a spray hood at the top of the snow cover, three snow baffles at both the left and right ends of the snow cover, an angle adjustment component on the snow cover for adjusting the snow baffles to different angles, a telescopic component on the snow cover connected to the snow baffles for extending and retracting the three snow baffles, and an angle adjustment component on the snow cover for driving the snow baffles to rotate.

[0007] Preferably, all three snow deflectors are connected by a sliding telescopic connection. The telescopic component includes a limiting block, which is installed on the snow deflector located in the middle and on the side of the snow deflector away from the snow cover. An expansion spring rod is installed inside the limiting block extending into the snow deflector. A pair of sliding rail seats are installed on the side of the snow deflector near the snow cover. A U-shaped slider is slidably connected in the pair of sliding rail seats. A moving block is installed at the end of the U-shaped slider away from the snow cover. One end of the moving block is located in the middle of the snow deflector away from the snow cover. A concave fixed seat is installed on the top of the snow cover. A roller is rotatably connected inside the fixed seat. A steel cable is installed inside the roller. A connecting block fixedly connected to the steel cable is installed in the middle of the U-shaped slider.

[0008] Preferably, an impact block is installed on the side of the snow shield away from the snow cover, and the side of the impact block facing away from the snow shield has a triangular structure.

[0009] Preferably, the angle adjustment assembly includes fixed blocks installed at both ends of the snow cover, a rotating rod rotatably connected to the fixed blocks installed on the snow baffle plate near the snow cover, an angle block installed on the top of the rotating rod, an adjustment block installed on the snow cover, the adjustment block having a semi-arc shape and multiple slots, an L-shaped support block installed on the top of the angle block, a rod inserted into one of the slots slidably connected to the horizontal end of the support block, and a compression spring sleeved below the rod.

[0010] Preferably, the insertion rod is located in the middle of the angle block, and a pull rod is installed at the end of the insertion rod away from the rotating rod.

[0011] Preferably, the top of the snow cover is equipped with a pair of U-shaped sliding blocks, and an adaptation block is connected inside the sliding blocks via a sliding rail. A spring adaptation rod that is slidably connected to the adaptation block is installed in the middle of the sliding blocks, and an adaptation wheel that passes through one end of a steel cable is installed on the top of the adaptation block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This invention, by setting up a snow removal device with a retractable component and an angle adjustment component, can flexibly adjust the snow removal width according to the changes in road width at different construction stages. When the road section becomes narrow due to roadbed widening, the snow baffle can be retracted or the angle can be adjusted inward to avoid affecting the surrounding unconstructed areas. After the road base is laid, the road section becomes wider, and the snow baffle can be extended or the angle can be adjusted outward to ensure that the snow in the construction area is completely cleared. This solves the problem that traditional fixed snow removal width devices cannot adapt to changes and greatly improves construction efficiency.

[0014] 2. This invention addresses the problem that traditional snow removal devices have fixed-length, non-foldable snow shields that occupy a lot of space in narrow sections or when not in operation. This device features a retractable and adjustable snow shield, which can be flexibly adjusted in narrow sections to reduce space occupation. When not in operation, the snow shield can be retracted and adjusted to a suitable angle, effectively reducing the overall size of the equipment, facilitating transportation and storage, and lowering transportation and storage costs.

[0023] 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.

[0024] like Figures 1-5 As shown, this utility model provides a snow removal device for highway construction, including a vehicle body 1. A snow cover 11 is installed at the front end of the vehicle body 1. A rotatable impeller rod 12 is installed inside the snow cover 11. The snow cover 11 has an arc-shaped structure, which facilitates the subsequent snow removal by the impeller rod 12, prevents snow from scattering, and improves snow removal efficiency. Its blades can break up the snow collected by the snow cover 11, disperse large pieces of snow, and use the thrust generated by rotation to push the snow in a designated direction, achieving efficient snow removal operation. A spray hood 13 is installed on the top of the snow cover 11. Three snow deflectors 14 are installed at both ends of the snow cover 11 to prevent snow pushed by the impeller rod 12 from splashing to both sides and guide the snow to the designated clearing area. The snow cover 11 is equipped with an angle adjustment component 3 for adjusting the snow deflectors 14 to different angles. The snow cover 11 is also equipped with a telescopic component 2, which is connected to the snow deflectors 14 and is used to extend and retract the three snow deflectors 14. The three snow deflectors 14 are all connected by a sliding telescopic connection. The telescopic component 2 includes a limiting block 21, which is installed on the snow deflector 14 located in the middle and the far side. On the side of the snow deflector 14 away from the snow cover 11, a limiting block 21 extends into the snow deflector 14 and is equipped with an expansion spring rod 22. When the steel cable 28 is relaxed, the expansion spring rod 22 pushes the limiting block 21 and the connected snow deflector 14 to extend. When the steel cable 28 is retracted, it can adapt to the retraction of the snow deflector 14, ensuring the smooth and stable extension and retraction of the snow deflector 14. A pair of sliding rail seats 23 are installed on the side of the snow deflector 14 near the snow cover 11. A U-shaped slider 24 is slidably connected in the pair of sliding rail seats 23. A moving block 25 is installed at the end of the U-shaped slider 24 away from the snow cover 11. The U-shaped slider 24 and the moving block 25 provide precise guidance for the extension and retraction of the snow deflector 14, ensuring that the snow deflector 14 runs smoothly and does not deviate during the extension and retraction process. One end of the moving block 25 is set in the middle of the snow deflector 14 away from the snow cover 11. A concave fixed seat 26 is installed on the top of the snow cover 11. A roller 27 is rotatably connected inside the fixed seat 26. A motor for driving the roller 27 to rotate is installed on the top of the fixed seat 26. A steel rope 28 is installed inside the roller 27. A connecting block 281 fixedly connected to the steel rope 28 is installed in the middle of the U-shaped slider 24.

[0025] It should be noted that when the snow deflector 14 needs to be extended to increase the snow removal width, the motor starts and drives the roller 27 to rotate. The rotation of the roller 27 causes the steel rope 28 wound inside it to loosen. At this time, the expansion spring rod 22, which was originally restricted by the steel rope 28, begins to extend due to the reduction of the tension of the steel rope 28. The limiting block 21 extends into the snow deflector 14 and is connected to the expansion spring rod 22. The extension of the expansion spring rod 22 causes the limiting block 21 to move outward, thereby causing the snow deflector 14 in the middle connected to the limiting block 21 and the snow deflector 14 away from the snow cover 11 to extend. At the same time, the U-shaped slider 24 slides in the slide rail seat 23. As the steel rope 28 loosens, the U-shaped slider 24 moves away from the snow cover 11. The moving block 25 on the U-shaped slider 24 also moves accordingly, pushing the snow deflector 14 away from the snow cover 11 to extend. Finally, the three snow deflectors 14 are extended as a whole, increasing the snow removal width.

[0026] When it is necessary to retract the snow deflector 14 to reduce the snow removal width or facilitate transportation and storage, the motor rotates in the reverse direction, driving the roller 27 to rotate in the reverse direction. The steel rope 28 begins to wind around the roller 27, and the steel rope 28 generates tension on the connecting block 281, which in turn pulls the U-shaped slider 24 to slide in the slide rail seat 23 towards the snow cover 11. The movement of the U-shaped slider 24 drives the moving block 25 to move, pushing the snow deflector 14 away from the snow cover 11 towards the snow cover 11. At the same time, the expansion spring rod 22 is compressed. As the steel rope 28 continues to wind, the limiting block 21 is also pulled to move inward into the snow deflector 14, ultimately causing the three snow deflectors 14 to retract in sequence, reducing the snow removal width.

[0027] The retractable component 2 of this invention can flexibly adjust the snow removal width by controlling the extension and retraction of the snow baffle 14, so that it can match the road width requirements of different construction stages. This avoids the problem that the fixed snow removal width of traditional snow removal devices cannot adapt to changes and affect the surrounding construction, thus improving the applicability and construction efficiency of the snow removal device. Moreover, the snow baffle 14 of this device can be retracted through the retractable component 2, which effectively reduces the overall size of the equipment. It can be flexibly adjusted when working in narrow road sections, avoiding occupying too much space and affecting traffic. In the non-operating state, it facilitates the transportation and storage of the equipment, reduces transportation and storage costs, and also improves the mobility and flexibility of the equipment.

[0028] like Figure 2 As shown, an impact block 29 is installed on the side of the snow shield 14 away from the snow cover 11. The side of the impact block 29 facing away from the snow shield 14 has a triangular structure.

[0029] The triangular impact block 29 can effectively break up snow piles and divide them into smaller parts, improving the snow removal efficiency and effect of the snow removal device. Moreover, the impact block 29 bears the impact before the snow baffle 14 and the vehicle body 1, dispersing the impact force encountered during the snow removal process and reducing damage to the snow baffle 14 and the vehicle body 1.

[0030] like Figure 1 and Figure 6 As shown, the snow cover 11 is provided with an angle adjustment assembly 3 for driving the snow deflector 14 to rotate. The angle adjustment assembly 3 includes fixed blocks 31 installed at the left and right ends of the snow cover 11. A rotating rod 32 is installed on the snow deflector 14 near the snow cover 11 and is rotatably connected to the fixed block 31. An angle block 33 is installed on the top of the rotating rod 32. An adjustment block 34 is installed on the snow cover 11. The adjustment block 34 has a semi-arc shape and multiple slots. An L-shaped support block 35 is also installed on the top of the angle block 33. A rod 36 inserted into one of the slots is slidably connected to the horizontal end of the support block 35. A compression spring 37 is sleeved below the rod 36.

[0031] It should be noted that when adjusting the angle of the snow shield 14, first pull the insert rod 36 upwards, compressing the spring 37. The insert rod 36 is then pulled out of the socket of the adjusting block 34. Next, rotate the snow shield 14. The snow shield 14 rotates on the fixing block 31 via the rotating rod 32, and the angle block 33 at the top of the rotating rod 32 rotates accordingly. When the snow shield 14 is rotated to the appropriate angle, release the insert rod 36. Under the elastic force of the compression spring 37, the insert rod 36 is inserted downwards into the corresponding socket on the adjusting block 34, thereby fixing the angle block 33 and thus fixing the angle of the snow shield 14. Because the adjusting block 34 is semi-circular and has multiple sockets, the snow shield 14 can be adjusted to different angles according to actual needs to adapt to different snow removal conditions and construction site requirements.

[0032] By adjusting the angle of the snow baffle 14, the effective snow removal width of the snow removal device can be changed. When the width of the road section narrows due to roadbed widening construction, the snow baffle 14 can be adjusted inward to reduce the snow removal width and avoid the snow removal device affecting the surrounding unconstructed areas. When the road section width increases after the road base is laid, the snow baffle 14 can be adjusted outward to expand the snow removal width and ensure that the snow in the construction area can be completely cleared. In this way, the snow removal width can be flexibly matched according to the changes in road width at different construction stages, improving the adaptability and construction efficiency of the snow removal device.

[0033] like Figure 6 As shown, the insertion rod 36 is located in the middle of the angle block 33, and a pull rod 38 is installed at the end of the insertion rod 36 away from the rotating rod 32.

[0034] Since the point of application of the force of the insert rod 36 is in the middle of the angle block 33, the force on the snow deflector 14 is more balanced during rotation, avoiding the snow deflector 14 from rotating unevenly or getting stuck due to the offset of the point of application of the force, thus allowing for more precise adjustment and fixation of the angle of the snow deflector 14.

[0035] like Figure 7 As shown, a pair of U-shaped slides 311 are installed on the top of the snow cover 11. An adaptation block 312 is connected inside the slide 311 through a slide rail. A spring adaptation rod 313 that is slidably connected to the adaptation block 312 is installed in the middle of the slide 311. An adaptation wheel 314 that passes through one end of the steel rope 28 is installed on the top of the adaptation block 312.

[0036] When the steel rope 28 is subjected to tension or moves, it will drive the adapting wheel 314 to rotate. The adapting block 312 will slide inside the slide block 311 via the slide rail. The spring adapting rod 313 in the middle of the slide block 311 will play a certain role in buffering and resetting the sliding of the adapting block 312. When the tension of the steel rope 28 changes, the spring adapting rod 313 will compress or extend according to the force, so that the adapting block 312 can flexibly adjust its position within the slide block 311 to adapt to different states of the steel rope 28 and ensure the tension and movement stability of the steel rope 28.

[0037] Through the cooperation of the adapting wheel 314 with the adapting block 312, the slide 311 and the spring adapting rod 313, the changes in tension on the steel rope 28 can be effectively buffered, avoiding sudden slack or excessive tension in the steel rope 28, thereby ensuring the stability of the steel rope 28 during operation, reducing the risk of wear and breakage caused by uneven force on the steel rope 28, and extending the service life of the steel rope 28.

[0038] The working principle is as follows: This snow removal device, used in highway construction, operates by having the operator start the motor. The motor drives the roller 27 to rotate, causing the steel rope 28 wound around it to gradually loosen. The expansion spring rod 22, originally bound by the steel rope 28, begins to extend due to the reduced tension. This extension pushes the connected limiting block 21 to move outwards. The movement of the limiting block 21 causes the snow baffle 14, located in the middle and furthest from the snow cover 11, to extend synchronously. During this process, the snow baffle 14, close to the snow accumulation layer, extends outwards. On one side of the snow deflector 14 of the snow cover 11, a U-shaped slider 24 installed in a pair of slide rail seats 23 begins to slide away from the snow cover 11 along the slide rail as the steel cable 28 is loosened. The moving block 25 connected to the end of the U-shaped slider 24 moves accordingly, thereby pushing the snow deflector 14 away from the snow cover 11 to extend outward. Finally, the three snow deflectors 14 are extended outward as a whole, effectively increasing the snow removal width. When it is necessary to retract the snow deflector 14, the operator controls the motor to reverse and retract it according to the above operation to reduce the snow removal width.

[0039] The operator pulls the lever 38 at one end of the insert rod 36, compressing the spring 37. The insert rod 36 is pulled out of the socket of the adjusting block 34. The snow deflector 14 is rotated so that the rotating rod 32 drives the angle block 33 to rotate synchronously. After reaching the appropriate angle, the lever 38 is released, and the insert rod 36 is inserted into the corresponding socket under the action of the spring, fixing the angle of the snow deflector 14.
