Description

Technical Field

[0001] This utility model relates to the field of snow and ice removal equipment technology, and more specifically, to an ice-breaking device and an ice-breaking vehicle. Background Technology

[0002] Winter snow and ice accumulation on roads pose a significant threat to traffic. Current snow removal and ice-breaking methods mainly include chemical and mechanical methods. Chemical methods use de-icing agents to remove road ice; they are simple and quick, but they damage the environment and roads, and their de-icing effect is not ideal at low temperatures. Mechanical methods mainly utilize ice-breaking devices such as ice scrapers or snowplows to remove ice or snow, or use ice-breaking rollers to break up ice. Currently, mechanical methods are still the most commonly used method for snow and ice removal.

[0003] However, most ice-breaking devices using mechanical methods are difficult to control in terms of breaking force. Excessive force can damage the road surface, while insufficient force cannot effectively separate the ice or snow layer from the road surface, failing to cleanly remove accumulated ice or snow.

[0037] Winter snow and ice accumulation on roads pose a significant threat to traffic. Current snow removal and ice-breaking methods mainly include chemical and mechanical methods. Chemical methods use de-icing agents to remove road ice; they are simple and quick, but they damage the environment and roads, and their effectiveness is not ideal at low temperatures. Mechanical methods primarily utilize ice-breaking devices such as ice scrapers or snowplows to remove ice or snow, or ice-breaking rollers. Currently, mechanical methods are still the most common method for ice and snow removal. However, it is difficult to control the breaking force of most mechanical ice-breaking devices. Excessive force can damage the road surface, while insufficient force cannot effectively separate the ice or snow layer from the road surface, failing to completely remove the accumulated ice or snow.

[0038] Based on this, please refer to Figure 1 The ice-breaking device 1000 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. The ice-breaking device 1000 can prevent the ice-breaking component 100 from damaging the road surface during operation and can improve the quality and efficiency of ice and snow removal. The ice-breaking device 1000 can be applied to ice-breaking equipment such as ice-breaking vehicles. All ice-breaking equipment with this ice-breaking device 1000 has the same functions as described above, and will not be elaborated further here.

[0039] The ice-breaking vehicle provided in the embodiments of this utility model includes a vehicle body and an ice-breaking device 1000. The ice-breaking device 1000 is disposed on the vehicle body, and the vehicle body moves with the ice-breaking device 1000 to perform large-area de-icing or snow removal. Of course, the ice-breaking device 1000 can also be installed on other ice-breaking equipment, which is not limited here.

[0040] The ice-breaking device 1000 in this embodiment will be described in detail below.

[0041] Because the road conditions requiring de-icing and snow removal are quite complex, in order to adapt to various road conditions and ensure the quality of de-icing and snow removal without damaging the road surface. Figure 1This is a schematic diagram from a first-view perspective of the ice-breaking device 1000 provided in an embodiment of the present invention; Figure 3 This is a schematic diagram of the buffer component 200 provided in an embodiment of the present invention. Please refer to [link / reference]. Figure 1 and combined Figure 3 In this embodiment, the ice-breaking device 1000 includes an ice-breaking component 100, a buffer component 200, and a lifting component 300. The buffer component 200 is hinged to the ice-breaking component 100 and is elastic. The lifting component 300 is connected to the end of the buffer component 200 away from the ice-breaking component 100; the lifting component 300 can drive the buffer component 200 to move along the Z-axis. In this embodiment, the buffer component 200 includes a buffer housing 210, a sliding connecting seat 220, and a spring 230. One end of the spring 230 is connected to the buffer housing 210, and the other end of the spring 230 is connected to the sliding connecting seat 220. The sliding connecting seat 220 is slidably connected to the buffer housing 210, and the buffer housing 210 is hinged to the ice-breaking component 100. The lifting component 300 is connected to the side of the sliding connecting seat 220 away from the spring 230; the lifting component 300 can drive the sliding connecting seat 220 to move relative to the buffer housing 210 along the Z-axis.

[0042] By incorporating a flexible buffer component 200, during snow and ice removal operations, when the road surface is uneven, the buffer component 200 can buffer, dampen, and absorb energy to prevent damage to the road surface during the operation of the ice-breaking component 100. Furthermore, the buffer component 200 can also buffer vibrations when the lifting component 300 raises or lowers it. In addition, the buffer component 200 is hinged to the ice-breaking component 100, meaning the ice-breaking component 100 can swing around the hinge point, ensuring that the ice-breaking component 100 remains in contact with the ground during operation, improving the quality and efficiency of snow and ice removal. The lifting component 300 allows the ice-breaking component 100 to adjust its height according to the thickness of the snow or ice for better snow and ice removal.

[0043] To ensure the ice-breaking component 100 better conforms to the ground, Figure 2 This is a schematic diagram from a second perspective of the ice-breaking device 1000 provided in an embodiment of this utility model; please refer to... Figure 1 and Figure 2In this embodiment, the lifting assembly 300 includes a fixed frame 310, a lifting frame 320, a lifting drive component 330, a first hinge shaft 340, and a second hinge shaft 350. One end of the lifting drive component 330 is hinged to the fixed frame 310 via the first hinge shaft 340; the other end of the lifting drive component 330 is hinged to the lifting frame 320 via the second hinge shaft 350. The lifting drive component 330 is used to drive the lifting frame 320 to move relative to the fixed frame 310 along the Z-axis direction. The lifting frame 320 is connected to the buffer assembly 200. The axis of the first hinge shaft 340 is parallel to the Y-axis direction; the Y-axis direction is perpendicular to the Z-axis direction; the first hinge shaft 340 and the second hinge shaft 350 are arranged in parallel. In this embodiment, the Y-axis direction is the travel direction of the icebreaker. The fixed frame 310 can be used to fix and connect to the body of the icebreaker. By hinged to the lifting drive component 330 and the fixed frame 310 and the lifting frame 320 respectively, the lifting drive component 330 and the lifting frame 320 can swing around the floating center 400, which can drive the buffer component 200 to swing, thereby driving the ice breaking component 100 to swing as well. This allows the ice breaking component 100 to adapt to the lateral slope of the road surface, ensuring that the ice breaking component 100 always adheres to the ground and completely breaks up the compacted snow or ice on the ground.

[0044] In this embodiment, the lifting drive component 330 is a hydraulic cylinder. Specifically, the fixed end of the hydraulic cylinder is hinged to the fixed frame 310 via a first hinge shaft 340, and the telescopic end of the hydraulic cylinder is hinged to the lifting frame 320 via a second hinge shaft 350. Of course, the lifting drive component 330 can also be replaced by other drive mechanisms such as an electric push rod, which is not limited here.

[0045] To provide sufficient lifting force, the number of lifting components 300 and buffer components 200 in this embodiment is two. Of course, the number of lifting components 300 and buffer components 200 can also be one, three, four, etc., and is not limited here.

[0046] Please continue reading. Figure 1 and Figure 2In this embodiment, the lifting frame 320 has a groove 321 extending along the Z-axis. A first roller assembly 311 is provided on the fixed frame 310, cooperating with the groove 321. The axis of the first roller assembly 311 is parallel to the Y-axis. The first roller assembly 311 prevents the lifting frame 320 from tipping over along the Y-axis. Furthermore, in this embodiment, the lifting frame 320 has a groove 321 extending along the Z-axis. A second roller assembly 312 is provided on the fixed frame 310, cooperating with the groove 321. The axis of the second roller assembly 312 is parallel to the X-axis, which is perpendicular to both the Z-axis and Y-axis. The second roller assembly 312 prevents the lifting frame 320 from tipping over along the X-axis. Both the first roller assembly 311 and the second roller assembly 312 can be provided simultaneously, or they can be provided separately; this is not limited here. By setting up the first roller group 311 and the second roller group 312, the moving friction between the lifting frame 320 and the fixed frame 310 can be reduced, thereby increasing the service life of the ice-breaking device 1000. In this embodiment, the chute 321 is a U-shaped groove that runs vertically through the device. Both the first roller group 311 and the second roller group 312 in this embodiment include two rollers, spaced apart. Of course, the number of rollers in the first roller group 311 and the second roller group 312 can also be one, three, four, etc., and is not limited here.

[0047] Existing ice-breaking devices typically require two separate units for both thick and thin ice, necessitating significant installation space and inconvenient operation. Please refer to [link / reference needed]. Figure 1 and Figure 2 In this embodiment, the ice-breaking assembly 100 includes a roller frame 110, an ice-breaking drive component 120, a roller shaft 130, a blade holder 140, and an ice-breaking blade 150. The roller frame 110 is hinged to the buffer assembly 200. The roller shaft 130 is disposed on the roller frame 110, and the blade holder 140 is sleeved on the roller shaft 130, with the ice-breaking blade 150 disposed on the blade holder 140. The ice-breaking drive component 120 is driveably connected to the roller shaft 130. When breaking snow or ice thicker than 10 mm, the ice-breaking drive component 120 operates to drive the roller shaft 130 to rotate. When breaking snow or ice thinner than 10 mm, the ice-breaking drive component 120 does not operate. Specifically, in this embodiment, the ice-breaking drive component 120 is a hydraulic motor, and the ice-breaking drive component 120 is driveably connected to the roller shaft 130 through a transmission box. Of course, the ice-breaking drive component 120 can also be replaced with other drive components such as a motor, which is not limited here. The transmission box can be equipped with gear transmission, chain transmission, etc., and is not limited here. With the above design, the ice-breaking device 1000 in this embodiment can meet the needs of both thick ice breaking and thin ice breaking, without the need for multiple devices to work together, thus saving workspace.

[0048] Please see Figure 3In this embodiment, the buffer assembly 200 also includes a connecting shaft seat 240. The connecting shaft seat 240 is provided on the outer wall of the buffer housing 210 away from the sliding connecting seat 220. The ice-breaking assembly 100 is hinged to the buffer housing 210 through the connecting shaft seat 240. By providing the connecting shaft seat 240, the connection strength between the buffer housing 210 and the ice-breaking assembly 100 can be improved, and it is also easier for the buffer housing 210 and the ice-breaking assembly 100 to be hinged, thereby ensuring that the ice-breaking assembly 100 can swing around the hinge point, so that the ice-breaking assembly 100 always keeps in contact with the ground during operation, thereby improving the quality and efficiency of ice and snow removal.

[0049] Specifically, the buffer assembly 200 in this embodiment includes a buffer box 210, a sliding connecting seat 220, a spring 230, and a connecting shaft seat 240. One end of the buffer box 210 has an opening 211. The spring 230 is disposed inside the buffer box 210, with one end of the spring 230 connected to the side of the buffer box 210 away from the opening 211, and the other end of the spring 230 connected to the sliding connecting seat 220. The sliding connecting seat 220 can move along the Z-axis direction inside the buffer box 210 under the drive of the spring 230. The side of the sliding connecting seat 220 away from the spring 230 is connected to the lifting assembly 300. The outer wall of the buffer box 210 away from the opening 211 is provided with a connecting shaft seat 240, and the ice-breaking assembly 100 is hinged to the buffer box 210 through the connecting shaft seat 240. By designing the buffer housing 210 as a hollow structure and placing the sliding connecting seat 220 inside the buffer housing 210, the overall height of the buffer assembly 200 can be reduced, thereby reducing the overall height of the ice-breaking device 1000 and saving space. By providing an opening 211 at one end of the buffer housing 210, the sliding connecting seat 220 can easily move relative to the buffer housing 210 along the Z-axis direction under the action of the lifting assembly 300. Of course, the buffer assembly 200 can also be designed with other structural forms, such as sliding the sliding connecting seat 220 to the outer wall of the buffer housing 210. The buffer housing 210 does not need to be designed as a hollow structure, nor does it need an opening 211 to accommodate the sliding connecting seat 220. The structure of the buffer assembly 200 is not limited here, as long as it can achieve the effect of buffering, shock absorption, and energy dissipation, and is easy to hinge with the ice-breaking assembly 100.

[0050] Specifically, spring 230 is preloaded during assembly. When the lifting drive 330 pushes down the lifting frame 320, the maximum downward pressure is less than the preload of spring 230, ensuring that the ice-breaking assembly 100 has the pressure applied by the lifting drive 330 during operation, while spring 230 is not compressed in the initial working state. During ice-breaking operations, when the road surface is uneven, the ice-breaking assembly 100 is forced to compress spring 230 by the force of upward-protruding hard obstacles, causing the ice-breaking assembly 100 to move upward. After passing over the hard obstacle, spring 230 returns to its original position, and the ice-breaking assembly 100 returns to its original position. By setting a buffer box, damage to the road surface by the ice-breaking assembly 100 during operation can be prevented.

[0051] Please continue reading. Figure 3 To limit the range of vertical movement of the sliding connecting seat 220 along the Z-axis and ensure the stability of the floating buffer assembly 200, the buffer assembly 200 in this embodiment further includes a first limiting block 250. The first limiting block 250 is disposed in the buffer housing 210 and is located away from the connecting shaft seat 240. The first limiting block 250 can abut against the sliding connecting seat 220 to limit its movement along the Z-axis. And / or, the buffer assembly 200 further includes a second limiting block 260. The second limiting block 260 is disposed in the buffer housing 210 and is located close to the connecting shaft seat 240. The second limiting block 260 can abut against the sliding connecting seat 220 to limit its movement along the Z-axis. That is, when the sliding connecting seat 220 moves upward to the position of the first limiting block 250, the first limiting block 250 jams the sliding connecting seat 220, preventing it from moving further upward. When the sliding connecting seat 220 moves downward to the position of the second limiting block 260, the second limiting block 260 locks the sliding connecting seat 220, preventing it from moving further downward. The first limiting block 250 and the second limiting block 260 can be set simultaneously or separately, which is not limited here. The positions of the first limiting block 250 and the second limiting block 260 can also be adjusted up and down along the Z-axis according to actual usage requirements. Furthermore, setting the first limiting block 250 and the second limiting block 260 can also prevent the spring 230 from being over-compressed and causing failure.

[0052] Specifically, in this embodiment, the buffer box 210 has an opening 211 at one end and an installation chamber. A first limiting block 250 is disposed on the inner wall of the buffer box 210, located within the installation chamber, and is positioned close to the opening 211. A second limiting block 260 is disposed on the inner wall of the buffer box 210, located within the installation chamber, and is positioned away from the opening 211.

[0053] Please see Figure 3To reduce friction between the sliding connecting seat 220 and the buffer housing 210 during relative movement, the buffer assembly 200 in this embodiment also includes a self-lubricating slider 270, through which the sliding connecting seat 220 is slidably connected to the buffer housing 210. The self-lubricating slider 270 automatically provides lubrication during operation, reducing friction and wear, and extending the service life of the buffer assembly 200. Furthermore, since the self-lubricating slider 270 does not require external lubricant, it reduces the generation of contaminants and minimizes pollution. Traditional sliders require periodic addition of lubricating oil or grease, while the self-lubricating slider 270 does not require frequent lubrication, reducing maintenance frequency and costs. Additionally, a groove 321 or guide rail can be provided on the inner wall of the buffer housing 210, with the sliding connecting seat 220 sliding or rolling with the groove 321 or guide rail via a slider or rolling element, thereby reducing the relative friction between the sliding connecting seat 220 and the buffer housing 210. Of course, other moving structures can also be provided, and are not limited here.

[0054] To prevent the spring 230 from bending left or right when it extends and retracts along the Z-axis, please refer to the following: Figure 3 In this embodiment, the buffer assembly 200 further includes a first guide sleeve 280, which is connected to the buffer housing 210, and a spring 230 is sleeved on the first guide sleeve 280; and / or, the buffer assembly 200 further includes a second guide sleeve 290, which is connected to the side of the sliding connecting seat 220 away from the lifting assembly 300, and a spring 230 is sleeved on the second guide sleeve 290. The first guide sleeve 280 and the second guide sleeve 290 allow the spring 230 to extend and retract along the first guide sleeve 280 and the second guide sleeve 290. That is, the spring 230 can be compressed and reset under the action of the guide sleeve. Of course, a guide post can also be provided between the sliding connecting seat 220 and the inner bottom wall of the buffer housing 210.

[0055] The working principle of the ice-breaking device 1000 provided in this embodiment is as follows:

[0056] When it is necessary to break up compacted snow or ice thicker than 10mm, the ice-breaking drive unit 120 operates, rotating and driving the roller shaft 130 to rotate rapidly via the transmission box. The ice-breaking blade 150 then quickly strikes and breaks up the snow and ice. When it is necessary to break up compacted snow or thin ice thinner than 10mm, the ice-breaking drive unit 120 does not operate; that is, the ice-breaking drive unit 120 does not provide rotational power. The roller shaft 130 presses against the road surface, and the movement of vehicles drags the roller shaft 130 to rotate, cracking the thin ice on the road surface.

[0057] In summary, the ice-breaking device 1000 includes an ice-breaking component 100, a buffer component 200, and a lifting component 300. The buffer component 200 includes a buffer housing 210, a sliding connecting seat 220, and a spring 230. One end of the spring 230 is connected to the buffer housing 210, and the other end is connected to the sliding connecting seat 220. The sliding connecting seat 220 is slidably connected to the buffer housing 210, and the buffer housing 210 is hinged to the ice-breaking component 100. The lifting component 300 is connected to the side of the sliding connecting seat 220 away from the spring 230. The lifting component 300 can drive the sliding connecting seat 220 to move relative to the buffer housing 210 along the Z-axis. By providing the elastic buffer component 200, during snow and ice removal operations, when the road surface is uneven, the buffer component 200 can buffer, dampen, and absorb energy to prevent the ice-breaking component 100 from damaging the road surface during operation. Furthermore, the buffer component 200 can also act as a buffer and shock absorber when the lifting component 300 raises or lowers it. In addition, the buffer component 200 is hinged to the ice-breaking component 100, meaning the ice-breaking component 100 can swing around the hinge point, ensuring that the ice-breaking component 100 remains in contact with the ground during operation, improving the quality and efficiency of ice and snow removal. By incorporating the lifting component 300, the ice-breaking component 100 can adjust its height according to the thickness of the snow or ice for better ice and snow removal.
