Description

Technical Field

[0001] This utility model relates to the field of road de-icing technology, and in particular to a double-row wheel icebreaker. Background Technology

[0002] In northern winters, snowfall can accumulate to 30-40 cm. If snow removal is not timely during heavy snowfalls, vehicles will compact the snow on the road surface, causing ice to form. This ice makes the road slippery, reducing friction and increasing the risk of accidents, traffic jams, and even road closures, greatly inconveniencing travelers. Traditional de-icing operations typically involve manual removal of snow and ice using shovels and brooms, which is costly and inefficient. To achieve efficient and rapid snow removal, highway maintenance companies often use de-icing vehicles equipped with road-breaking devices.

[0003] Existing road icing devices typically consist of a single or a pair of icing rollers nearly the width of the road surface, equipped with ice-breaking spikes for piercing the ice. The device is mounted at the front of construction machinery, and the icing rollers crush the ice crust as the machinery moves forward. However, when traversing potholes, existing road icing devices often result in only part of the icing rollers contacting the ground, while the rest remains suspended. The icing roller in the pothole cannot make contact with the ground, preventing complete ice breaking; simultaneously, when the icing roller at the top of the pothole contacts the ground, its entire weight is applied to the protruding surface, causing the ice-breaking spikes to pierce the road surface and damage it. Utility Model Content

[0004] This invention addresses the problem that existing road ice-breaking devices, when traversing potholes, result in only part of the ice-breaking roller contacting the ground while the rest remains suspended. The ice-breaking roller in the pothole cannot contact the ice crust, thus failing to completely break up the ice, leading to incomplete ice breaking. Simultaneously, when the ice-breaking roller at the top of the pothole contacts the ground, its entire weight is applied to the protruding road surface, causing ice spikes to puncture and damage the road surface. Therefore, this invention provides a double-row wheel ice-breaking machine to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is:

[0006] A double-row wheel icebreaker includes a support frame, a connecting rod, a connecting frame, and ice-breaking wheels; the connecting rod is fixed on the support frame and is hinged to the connecting frame; two rows of ice-breaking devices are installed on the support frame, and each row of ice-breaking devices consists of multiple ice-breaking wheels that can float up and down independently.

[0007] It also includes a floating connection device or an elastic device. The ice-breaking wheel is floatingly connected to the support frame through the floating connection device or the elastic device inside the wheel body. Multiple crushing devices are evenly arranged on the circumferential direction of the ice-breaking wheel.

[0008] Furthermore, the support frame is provided with a connecting part, and multiple sets of floating connecting devices are installed at the lower end of the connecting part, with an ice-breaking wheel installed at the lower end of each set of floating connecting devices.

[0009] Furthermore, the floating connection device is a support arm hinged to the lower end of the connection part, and a torsion spring is provided on the connection part to give the support arm a downward rotation tendency.

[0010] Furthermore, the floating connection device is a damping rod or rubber block fixed to the lower end of the connection part.

[0011] Furthermore, the support frame is rotatably connected to two shafts, and each shaft is floatingly connected to multiple ice-breaking wheels via multiple sets of elastic devices.

[0012] Furthermore, the elastic device consists of multiple springs circumferentially and evenly installed between the rotating shaft and the ice-breaking wheel.

[0013] Furthermore, the support frame is provided with a counterweight beam, and multiple counterweight blocks are detachably installed on the counterweight beam.

[0014] Furthermore, the ice-breaking device in the ice-breaking wheel adopts an arc-shaped toothed blade.

[0015] Furthermore, the arc-shaped cutting edges of adjacent ice-breaking wheels rotate in opposite directions; the arc-shaped cutting edges of the ice-breaking wheel at the front end of the ice-breaking machine and the arc-shaped cutting edges of the ice-breaking wheel at the rear end of the ice-breaking machine rotate in opposite directions.

[0016] Furthermore, the ice-breaking device in the ice-breaking wheel adopts a pyramidal ice-breaking nail.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. A double-row wheel icebreaker, comprising multiple ice-breaking wheels, each capable of independently floating up and down. These wheels achieve their floating and pressure-applying action on the ground via a floating connection device or elastic mechanism. When traversing uneven surfaces, the ice-breaking wheel that passes over higher sections floats upwards, while the one that passes over lower sections floats downwards, ensuring equal pressure is applied to icy surfaces at varying heights. This allows the ice to be broken up at both higher and lower points in the uneven surface. Compared to traditional ice-breaking rollers, this icebreaker can effectively break up ice shells in potholes. Furthermore, the equal pressure applied to the ground by each ice-breaking wheel when traversing uneven surfaces avoids the damage to the road surface caused by excessive force on some ice-breaking wheels being suspended in the air, as is common with traditional ice-breaking devices.

[0019] 2. The icebreaker is equipped with a counterweight beam, on which multiple counterweight blocks are detachably mounted. By adding or removing counterweight blocks, the overall weight of the icebreaker is changed, thereby altering the crushing pressure between the ice-breaking wheel and the surface ice. The number of counterweight blocks is adjusted according to the thickness of the ice layer on the road surface, maximizing ice-breaking efficiency while ensuring no damage to the road surface.

[0020] 3. The ice-breaking wheel is equipped with arc-shaped toothed blades for breaking ice. Since the arc-shaped toothed blades on the ice-breaking wheel will slide along the direction of the toothed blades on the ice surface, the arc-shaped toothed blades on adjacent ice-breaking wheels are arranged in opposite directions so that the sliding along the direction of the toothed blades on adjacent ice-breaking wheels cancels each other out, thereby canceling out the lateral sliding generated by the construction machinery during the operation.

[0021] 4. The arc-shaped toothed blades of the ice-breaking wheel at the front and the arc-shaped toothed blades of the ice-breaking wheel at the rear of the ice-breaking machine rotate in opposite directions. When crushing the ice shell on the road surface, the cutting blades formed by the ice-breaking wheel at the front and the ice-breaking wheel at the rear of the ice-breaking machine intersect, making the cut ice shell on the road surface rhomboid. The ice-breaking wheel at the rear of the ice-breaking machine can more easily cut the ice shell and remove it from the road surface. Attached Figure Description

[0029] Specific implementation method one: See Figure 1-6As shown, a double-row wheel icebreaker, in this embodiment, includes a support frame 1, a connecting rod 2, a connecting frame 3, and ice-breaking wheels 401; the connecting rod 2 is fixed on the support frame 1, the connecting rod 2 is hinged to the connecting frame 3, and two rows of ice-breaking devices are installed on the support frame 1, each row of ice-breaking devices is composed of multiple ice-breaking wheels 401 that can float up and down independently;

[0030] It also includes a floating connection device 403 or an elastic device 406. The ice-breaking wheel 401 is floatingly connected to the support frame 1 through the floating connection device 403 or the elastic device 406 inside the wheel body. Multiple crushing devices are evenly arranged on the ice-breaking wheel 401 in the circumferential direction.

[0031] Furthermore, the connecting frame 3 is equipped with a lifting device for raising the support frame 1 away from the ground. The lifting device consists of a lifting arm and a telescopic rod. The lower end of the lifting arm is hinged to the connecting frame 3, the fixed end of the telescopic rod is hinged to the middle of the connecting frame 3, and the movable end of the telescopic rod is hinged to the middle of the lifting arm. The other end of the lifting arm is connected to the support frame 1 via a chain. When the telescopic rod extends, it drives the lifting arm to rotate upward, and the lifting arm, via the chain, drives the support frame 1 to move upward around the hinge point of the connecting rod 2, thereby raising the support frame 1 and the ice-breaking wheel 401 away from the ground, facilitating equipment transportation in a non-ice-breaking state. When the telescopic rod shortens, it drives the lifting arm to rotate downward, and the lifting arm, via the chain, drives the support frame 1 to move downward around the hinge point of the connecting rod 2, thereby lowering the support frame 1 and the ice-breaking wheel 401 and bringing the ice-breaking wheel 401 into contact with the ground to complete the ice-breaking operation.

[0032] Furthermore, the icebreaker is equipped with multiple ice-breaking wheels 401 for breaking ice. Each ice-breaking wheel 401 can float up and down independently. The ice-breaking wheel 401 achieves its up-and-down floating and applying pressure to the ground through a floating connection device 403 or an elastic device 406. When driving on potholes, the ice-breaking wheel 401 that passes over the higher parts of the road floats upward, and the ice-breaking wheel 401 that passes over the lower parts of the road floats downward, achieving equal pressure on the icy ground at different heights. This ensures that the ice surface at both the higher and lower parts of the potholes is broken by the ice-breaking wheel 401. Compared with traditional ice-breaking rollers, this icebreaker can break the ice shell at potholes. Moreover, when driving on potholes, each ice-breaking wheel 401 applies pressure to the ground, avoiding the damage to the road surface caused by excessive force when some ice-breaking wheels 401 are suspended in the air, as is common with traditional ice-breaking devices.

[0033] Specific Implementation Method Two: See Figure 1 and 3 As shown in Figure 4, the support frame 1 of this embodiment is provided with a connecting part 402. Multiple sets of floating connecting devices 403 are installed at the lower end of the connecting part 402, and an ice-breaking wheel 401 is installed at the lower end of each set of floating connecting devices 403.

[0034] Specific implementation method three: See Figure 1 and 3 As shown in Figure 4, the floating connection device 403 in this embodiment is a support arm hinged to the lower end of the connection part 402, and a torsion spring is provided on the connection part 402 to give the support arm a downward rotation tendency.

[0035] Furthermore, the ice-breaking wheel 401 is provided with a rotating shaft, which is rotatably connected to the lower end of the support arm. The torsion spring, through the support arm, causes the ice-breaking wheel 401 to have a downward tendency, applying pressure to the ice-breaking wheel 401 to keep it in contact with the road surface. As an alternative implementation, the torsion spring can be a spring installed between the support frame 1 and the support arm, pushing the support arm to rotate downward.

[0036] Detailed Implementation Method Four: See [link] Figure 1 and 3 As shown in Figure 4, the floating connection device 403 in this embodiment is a damping rod or rubber block fixed to the lower end of the connection part 402.

[0037] Furthermore, the floating connection device 403 achieves vertical floating connection via rubber blocks. The upper end of the floating connection device 403 is a fixed seat, which is fixedly connected to the connecting part 402 by bolts. The fixed seat is detachably fixed to the upper end of the rubber block by through bolts, and the lower end of the rubber block is detachably fixed to the axle seat by bolts. A rotating shaft is rotatably connected to the axle seat at the center of the ice-breaking wheel 401. When the ice-breaking wheel 401 contacts the ground, the rubber blocks in the floating connection device 403 all bend and deform upwards. When traveling to a pothole, the deformation of the rubber blocks returns to its original shape, driving the ice-breaking wheel 401 into the pothole to break the ice shell on the road surface. The connection using damping rods works similarly to the rubber blocks. When the ice-breaking wheel 401 contacts the ground, the damping rods in the floating connection device 403 all retract. When traveling to a pothole, the retracted damping rods extend, driving the ice-breaking wheel 401 into the pothole to break the ice shell on the road surface.

[0038] Specific implementation method five: See Figure 2 and 5 As shown in Figure 6, in this embodiment, the support frame 1 is rotatably connected to two rotating shafts 404, and each rotating shaft is floatingly connected to multiple ice-breaking wheels 401 through multiple sets of elastic devices 406.

[0039] Specific Implementation Method Six: See Figure Figure 2 and 5 As shown in Figure 6, the elastic device 406 in this embodiment consists of multiple springs that are circumferentially and evenly installed between the rotating shaft 404 and the ice-breaking wheel 401.

[0040] Furthermore, multiple circumferentially arranged elastic devices 406 are fixed at one end to the rotating shaft 404 and at the other end to the inner hub of the ice-breaking wheel 401, allowing each ice-breaking wheel 401 to float up and down relative to the rotating shaft 404 when subjected to different pressures. As an alternative implementation, the elastic device 406 is a damping rod.

[0041] Detailed implementation method seven: See Figure 1 and 3 As shown in Figure 4, the support frame 1 of this embodiment is provided with a counterweight beam 501, and a plurality of counterweight blocks 502 are detachably installed on the counterweight beam 501.

[0042] Furthermore, by adding or removing counterweights 502, the overall weight of the icebreaker is altered, thereby changing the crushing pressure between the ice-breaking wheel 401 and the surface ice. The number of counterweights 502 is adjusted according to the thickness of the ice layer on the road surface, maximizing ice-breaking efficiency while ensuring no damage to the road surface.

[0043] Detailed Implementation Method Eight: See also Figure 1 and 3 As shown in Figure 4, the ice-breaking device in the ice-breaking wheel 401 of this embodiment adopts an arc-shaped toothed blade.

[0044] Detailed implementation method nine: See Figure 1 and 3 As shown in Figure 4, in this embodiment, the arc-shaped teeth of adjacent ice-breaking wheels 401 rotate in opposite directions. The arc-shaped teeth of the ice-breaking wheel 401 at the front end of the ice-breaking machine and the arc-shaped teeth of the ice-breaking wheel 401 at the rear end of the ice-breaking machine rotate in opposite directions.

[0045] Detailed Implementation Method Ten: See [link] Figure 5-6 As shown, the ice-breaking device in the ice-breaking wheel 401 of this embodiment adopts a pyramidal ice-breaking nail.

[0046] Furthermore, since the arc-shaped cutting edges on the ice-breaking wheel 401 will slide along the direction of the cutting edges on the ice surface, the arc-shaped cutting edges on adjacent ice-breaking wheels 401 are arranged with opposite rotation directions. This causes the sliding along the direction of the cutting edges on adjacent ice-breaking wheels 401 to cancel each other out, thereby canceling out the lateral sliding generated by the construction machinery during operation. The arc-shaped cutting edges of the ice-breaking wheel 401 at the front end of the ice-breaking machine and the ice-breaking wheel 401 at the rear end of the ice-breaking machine are arranged with opposite rotation directions. When crushing the ice shell on the road surface, the cutting edges formed by the ice-breaking wheel 401 at the front end and the ice-breaking wheel 401 at the rear end of the ice-breaking machine intersect, making the cut ice shell on the road surface rhomboid. The ice-breaking wheel 401 at the rear end of the ice-breaking machine can more easily cut the ice shell and remove it from the road surface.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention 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 of the technical features.
