Description

Technical Field

[0001] The present invention relates to the technical field of road and bridge maintenance equipment, and in particular to a deicing device for road and bridge maintenance and a use method thereof. Background Art

[0002] In the maintenance of roads and bridges, winter road icing is a major hidden danger that affects traffic safety. Timely and effective deicing operations are crucial to ensuring the normal use of roads and bridges. At present, there are various common methods for deicing roads and bridges, including manual deicing, mechanical crushing and deicing, and spreading snow-melting agents. Manual deicing is inefficient and labor-intensive, making it difficult to cope with large areas of icy roads. Mechanical crushing and deicing equipment often only has a single ice-breaking function, and the ice and snow after crushing are not cleaned thoroughly. In addition, the crushed parts are easily affected by the adhesion of ice and snow, which affects the operation effect. Simply spreading snow-melting agents for deicing is not only difficult to accurately control the amount used, but excessive use can also cause damage to the road structure and the surrounding environment. At the same time, it has limited effect on thicker ice layers.

[0003] However, the existing technology still has obvious shortcomings: First, most of the equipment functions are relatively simple or have poor coordination, and the mechanical crushing device lacks effective follow-up ice and snow cleaning and anti-freezing measures. The device that simply spreads snow-melting agents is difficult to remove the hard ice layer that has formed, resulting in incomplete de-icing effect and inability to prevent the road surface from refreezing in the long term. Secondly, for mechanical ice-breaking equipment, its core ice-crushing wheel is very easy to be adhered and covered by broken ice and snow debris during operation, which not only reduces the ice crushing efficiency, but also seriously affects the continuity of operation due to frequent shutdowns for cleaning. Furthermore, the existing snow-melting agent delivery mechanism mostly uses simple valve opening and closing or constant-speed rotating spreading discs, and the control of delivery amount and frequency is relatively extensive, making it difficult to achieve precise delivery on demand, which can easily cause waste of snow-melting agents and environmental pollution, and it is also impossible to accurately form a long-term anti-freeze protection layer on the road surface after clearing. For this purpose, a de-icing device for road and bridge maintenance is provided to solve the above problems. Summary of the Invention

[0011] Preferably, the guide rod is adapted to the guide through hole, and the guide rod slides up and down inside the guide through hole. The two ends of the support spring are respectively fixedly connected to the bottom of the guide through hole and the top of the ice-crushing guide push plate. When the support spring is naturally extended without being subjected to external force, the ice-crushing guide push plate fits tightly against the ground.

[0012] Preferably, the rotating shaft of the second drive motor and both ends of each group of cleaning brush wheels are provided with transmission gears. The rotating shaft of the second drive motor is connected to one group of cleaning brush wheels through a chain transmission, and each two groups of cleaning brush wheels are also connected through a link transmission. The inner side of the cleaning brush wheel is made of metal, and the outer side is wrapped with a brush that fits tightly with the supporting beam.

[0013] Preferably, the liquid inlet end of the liquid pump passes through a hose to the inner cavity of the de-icing liquid storage tank near the inner bottom wall, and the liquid outlet end of the liquid pump is connected to the flow equalizing plate through a hose. The de-icing liquid storage tank and the liquid pump are both fixedly connected above the main frame of the ice crushing truck.

[0014] The present invention also provides a method for using a deicing device for road and bridge maintenance. The specific deicing method is: Step 1: After the device is started, the first drive motor 12 starts to operate, and the gears and chains on its rotating shaft drive the ice crushing front wheel 14 to rotate, pushing the device forward. The ice crushing front wheel 14 crushes and breaks the ice layer on the surface of the road and bridge. At the same time, during the movement of the device, the ice crushing guide push plate 19 is kept in close contact with the ground under the elastic action of the support spring 110, and the ice and snow fragments crushed by the ice crushing front wheel 14 are steadily pushed to both sides of the road along its inclined surface, completing the preliminary cleaning; Step 2: While the ice-crushing front wheel 14 is working, the second drive motor 22 of the ice-crushing wheel cleaning mechanism 2 is started, and all the cleaning brush wheels 23 are driven to rotate synchronously through the chain and the transmission gear. The brush wrapped on the outside of the cleaning brush wheel 23 continuously brushes the surface of the ice-crushing front wheel 14 to remove the snow and ice chips adhering thereto, and prevent the accumulation from affecting the crushing effect. In order to further enhance the cleaning effect and prevent the wheel surface from freezing, the ice-crushing wheel flushing mechanism 3 is started intermittently, and the liquid pump 32 draws de-icing liquid from the de-icing liquid storage tank 31 and transports it to the flow equalizing plate 33. The liquid is sprayed onto the surface of the ice-crushing front wheel 14 and the ground area in front after the crushing process through the multiple groups of atomizing nozzles 34 thereon, so as to flush the residual crushed ice and assist in melting. Step 3: After the ice layer has been broken, preliminarily cleaned, and passed through the area sprayed with de-icing fluid, the de-icing agent dispensing mechanism 4 begins operation. Its third drive motor 46 drives the lower turntable 47 to rotate. When the lower discharge hole 48 on the lower turntable 47 overlaps with the upper discharge hole 45 at the bottom of the de-icing agent storage hopper 43, the de-icing agent particles fall into the guide tube 44 through the overlapping holes under the action of gravity and are finally spread on the treated clean road surface. By controlling the speed of the third drive motor 46 and adjusting the rate and timing of the hole overlap, the intermittent de-icing agent dispensing amount and frequency can be precisely controlled, thereby effectively preventing the re-freezing of road surface water or the rapid freezing of newly fallen snow. Step 4. During the entire operation of the device, if the road surface is uneven and causes the ice-crushing guide push plate 19 to be subjected to an upward force, the guide rod 18 will slide upward along the guide through hole 16 on the support beam 15, compressing the support spring 110, allowing the push plate to be lifted briefly. After passing the unevenness, the support spring 110 releases the elastic force, pushing the guide rod 18 and the ice-crushing guide push plate 19 to reset, so that they are close to the ground again, ensuring the continued effectiveness and adaptability of the ice pushing operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes a road ice crushing and clearing mechanism, an ice-crushing wheel sweeping mechanism, an ice-crushing wheel flushing mechanism, and a deicing agent delivery mechanism to achieve a complete process from ice crushing, wheel surface cleaning, assisted ice melting, to road surface anti-freezing and refreezing. This integrated design effectively overcomes the limitations of a single deicing method, significantly improving deicing efficiency and effectiveness, ensuring that road and bridge surfaces return to a safe state for traffic and preventing refreezing.

[0016] 2. The brush wheel of the present invention's ice-crushing wheel cleaning mechanism continuously removes accumulated snow and ice debris from the surface of the front ice-crushing wheel. Combined with the intermittent spraying and flushing of de-icing fluid by the ice-crushing wheel flushing mechanism, this dual-action cleanliness guaranteeing the cleanliness of the front ice-crushing wheel's working surface. This self-cleaning mechanism effectively prevents ice and snow from accumulating on the working components, ensuring that the core components of the ice-crushing device are always in efficient operation, guaranteeing the continuity and efficiency of ice-crushing operations.

[0017] 3. The de-icing agent dispensing mechanism of the present invention adopts a design in which a third drive motor drives the lower turntable to rotate and control the opening and closing. By adjusting the motor speed, the frequency and timing of the overlap of the lower and upper discharge holes can be precisely controlled, thereby achieving flexible and reliable adjustment of the de-icing agent dispensing amount and frequency, achieving the purpose of effectively preventing residual moisture or new snow on the road surface from freezing, and avoiding waste and pollution caused by excessive dispensing.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes an embodiment of the present invention based on its overall structure.

[0022] Example 1 like Figures 1 to 8 As shown, a deicing device for road and bridge maintenance includes: The road ice crushing and cleaning mechanism 1 is used to crush the ice on the surface of the road bridge and push it to both sides. The road ice crushing and cleaning mechanism 1 includes an ice crushing vehicle main frame 11. A first drive motor 12 is fixedly connected to the top of the ice crushing vehicle main frame 11. An auxiliary rear wheel 13 and an ice crushing front wheel 14 are rotatably connected to the bottom of the ice crushing vehicle main frame 11. Gears are fixedly connected to the rotating shaft of the first drive motor 12 and the outer side of the ice crushing front wheel 14. The rotating shaft of the first drive motor 12 and the ice crushing front wheel 14 are connected by a chain drive. The ice-crushing wheel cleaning mechanism 2 is arranged on the inner side of the road ice crushing and cleaning mechanism 1 near the ice-crushing front wheel 14. The ice-crushing wheel cleaning mechanism 2 is used to continuously clean the snow on the ice-crushing front wheel 14; The ice-crushing wheel flushing mechanism 3 is arranged above the road ice crushing and cleaning mechanism 1 and near the ice-crushing front wheel 14. The ice-crushing wheel flushing mechanism 3 is used to intermittently spray de-icing liquid on the ice-crushing front wheel 14 and the ground to flush the ice-crushing front wheel 14 to prevent snow or ice from adhering. It cooperates with the ice-crushing wheel cleaning mechanism 2 to enhance the cleaning effect of the ice-crushing front wheel 14; The snow-melting agent delivery mechanism 4 is arranged on the inner side of the road ice crushing and cleaning mechanism 1. The snow-melting agent delivery mechanism 4 is used to intermittently deliver snow-melting agent to the road surface after the crushed ice cleaning treatment to prevent snow accumulation or re-freezing of the road surface.

[0023] The above scheme is adopted: after the first drive motor 12 is started, its rotating shaft drives the ice-crushing front wheel 14 to rotate through the transmission action of gears and chains. The ice-crushing front wheel 14 breaks the ice layer on the surface of the road and bridge during the rotation process. The auxiliary rear wheel 13 cooperates with the ice-crushing front wheel 14 to realize the movement of the ice-crushing vehicle main frame 11, so that the device can continue to move forward. At the same time, the ice-crushing wheel cleaning mechanism 2 continues to clean the snow on the ice-crushing front wheel 14, and the ice-crushing wheel flushing mechanism 3 intermittently sprays deicing liquid to enhance the cleaning effect. The snow-melting agent delivery mechanism 4 intermittently delivers snow-melting agent to the treated road surface to prevent it from re-icing.

[0024] A supporting crossbeam 15 is fixedly connected to the top of the main frame 11 of the ice crushing vehicle, and two groups of guide through holes 16 are opened on the inner side of the supporting crossbeam 15. An ice crushing guide push plate 19 is provided below the supporting crossbeam 15 to push the crushed ice and snow to both sides. Two groups of guide rods 18 are fixedly connected to the top of the ice crushing guide push plate 19, and a support spring 110 is sleeved on the outer side of the guide rod 18. Several groups of positioning studs 111 are fixedly connected to the top of the main frame 11 of the ice crushing vehicle at equal intervals. The guide rods 18 are adapted to the guide through holes 16, and the guide rods 18 slide up and down inside the guide through holes 16. The two ends of the support spring 110 are respectively fixedly connected to the bottom of the guide through holes 16 and the top of the ice crushing guide push plate 19. When the support spring 110 is naturally extended without being subjected to external force, the ice crushing guide push plate 19 is in close contact with the ground.

[0025] The above scheme is adopted: during the operation of the device, the ice-crushing guide push plate 19 is tightly fitted with the ground under the elastic force of the support spring 110. When encountering an uneven road surface, the ice-crushing guide push plate 19 will be driven by the force of the ground to drive the guide rod 18 to slide up and down inside the guide through hole 16, and the support spring 110 will expand and contract accordingly, thereby adaptively adjusting the height of the ice-crushing guide push plate 19 to ensure that it always remains in contact with the ground, thereby stably pushing the ice and snow crushed by the road ice crushing and cleaning mechanism 1 to both sides.

[0026] The ice-crushing wheel cleaning mechanism 2 includes a fixed shell 21, a second drive motor 22 is embedded in the interior of the fixed shell 21, and several groups of cleaning brush wheels 23 are equidistantly connected to the inner side of the fixed shell 21. The rotating shaft of the second drive motor 22 and both ends of each group of cleaning brush wheels 23 are provided with transmission gears. The rotating shaft of the second drive motor 22 is connected to one group of cleaning brush wheels 23 through a chain transmission, and each two groups of cleaning brush wheels 23 are also connected through a link transmission. The inner side of the cleaning brush wheel 23 is made of metal, and the outer side is covered with a brush that fits tightly with the supporting beam 15.

[0027] The above solution is adopted: after the second drive motor 22 is started, its rotating shaft drives one group of cleaning brush wheels 23 to rotate through the transmission action of the chain and the transmission gear. Since every two groups of cleaning brush wheels 23 are connected by chain transmission, all cleaning brush wheels 23 rotate synchronously, and the brushes on the outer side of the cleaning brush wheel 23 are in close contact with the ice crushing front wheel 14. During the rotation process, the snow attached to the ice crushing front wheel 14 is continuously cleaned to prevent the accumulation of snow or the attachment of ice cubes from affecting the crushing effect of the ice crushing front wheel 14.

[0028] The ice-crushing wheel flushing mechanism 3 includes a de-icing liquid storage tank 31, a liquid pump 32 is provided on the side of the de-icing liquid storage tank 31, a flow equalizing plate 33 is fixedly connected to the inner side of the main frame 11 of the ice-crushing vehicle, and a plurality of groups of atomizing nozzles 34 are fixedly connected to the flow equalizing plate 33 at equal distances near the side of the ice-crushing front wheel 14. The liquid inlet end of the liquid pump 32 passes through a hose to the position of the inner cavity of the de-icing liquid storage tank 31 near the inner bottom wall, and the liquid outlet end of the liquid pump 32 is connected to the flow equalizing plate 33 through a hose. The de-icing liquid storage tank 31 and the liquid pump 32 are both fixedly connected above the main frame 11 of the ice-crushing vehicle.

[0029] The above scheme is adopted: after the liquid pump 32 is started, the de-icing liquid is extracted from the de-icing liquid storage tank 31 through the hose at the liquid inlet end, and the extracted de-icing liquid is transported to the flow equalizing plate 33 through the hose at the liquid outlet end of the liquid pump 32. The flow equalizing plate 33 evenly distributes the de-icing liquid to several groups of atomizing nozzles 34. The atomizing nozzles 34 atomize the de-icing liquid and spray it onto the ice-crushing front wheel 14 and the ground. On the one hand, it can flush the snow or ice attached to the ice-crushing front wheel 14 to prevent it from remaining. On the other hand, it cooperates with the cleaning brush wheel 23 of the ice-crushing wheel cleaning mechanism 2 to further enhance the cleaning effect of the ice-crushing front wheel 14. At the same time, the de-icing liquid sprayed on the ground also helps subsequent de-icing operations.

[0030] The de-icing agent dispensing mechanism 4 includes a positioning plate 41, two sets of locking nuts 42 are rotatably connected to the top of the positioning plate 41, a de-icing agent storage bucket 43 is fixedly connected to the inside of the positioning plate 41, a guide tube 44 is threadedly connected to the bottom of the de-icing agent storage bucket 43, an upper discharge hole 45 is opened on the inner bottom wall of the de-icing agent storage bucket 43 to penetrate to the bottom thereof, a third drive motor 46 is fixedly connected to the inner bottom wall of the de-icing agent storage bucket 43, a rotating shaft of the third drive motor 46 penetrates to the bottom of the de-icing agent storage bucket 43 and is fixedly connected to a lower turntable 47, and a hole is opened above the lower turntable 47 to fit the upper discharge hole 45. The lower discharge hole 48 and the lower turntable 47 fit together with the bottom of the snow-melting agent storage bucket 43. When it is necessary to fix or replace the snow-melting agent dispensing mechanism 4 above the main frame 11 of the ice crushing vehicle, it is only necessary to rotate the two sets of locking nuts 42 to remove the old snow-melting agent dispensing mechanism 4 from the top of the main frame 11 of the ice crushing vehicle and replace it with a new snow-melting agent dispensing mechanism 4. The positioning studs 111 are used to penetrate the positioning plate 41 and threadedly connect with the locking nuts 42. By tightening the two sets of locking nuts 42, the speed of the upper discharge hole 45 and the ice-crushing wheel flushing mechanism 3 can be adjusted by controlling the speed of the third drive motor 46.

[0031] The above solution is adopted: the snow-melting agent is pre-stored in the snow-melting agent storage bucket 43, and the third drive motor 46 drives the lower turntable 47 to rotate after it is started. When the lower discharge hole 48 on the lower turntable 47 rotates to coincide with the upper discharge hole 45 of the snow-melting agent storage bucket 43, the snow-melting agent in the snow-melting agent storage bucket 43 enters the guide tube 44 through the upper discharge hole 45 and the lower discharge hole 48 in turn, and is discharged onto the road surface after the crushed ice cleaning treatment through the guide tube 44. By controlling the speed of the third drive motor 46, the coincidence rate and timing of the lower discharge hole 48 and the upper discharge hole 45 can be changed, thereby achieving intermittent delivery of snow-melting agent. When it is necessary to fix or replace the snow-melting agent delivery mechanism 4, the locking nut 42 is rotated to separate it from the positioning stud 111, and the old mechanism can be removed. After replacing the new mechanism, the positioning stud 111 is made to pass through the positioning plate 41, and then the locking nut 42 is threadedly connected to the positioning stud 111 and tightened to achieve the fixation of the snow-melting agent delivery mechanism 4.

[0032] Example 2 like Figures 1 to 8 As shown, a method for using a de-icing device for road and bridge maintenance includes the following steps: step 1: after the device is started, the first drive motor 12 is operated, and the gear and chain on the rotating shaft drive the ice crushing front wheel 14 to rotate, pushing the device forward. The ice crushing front wheel 14 crushes and breaks the ice layer on the surface of the road and bridge. At the same time, during the movement of the device, the ice crushing guide push plate 19 is kept in close contact with the ground under the elastic action of the support spring 110, and the ice and snow fragments crushed by the ice crushing front wheel 14 are steadily pushed to both sides of the road along its inclined surface, completing the preliminary cleaning; Step 2: While the ice-crushing front wheel 14 is working, the second drive motor 22 of the ice-crushing wheel cleaning mechanism 2 is started, and all the cleaning brush wheels 23 are driven to rotate synchronously through the chain and the transmission gear. The brush wrapped on the outside of the cleaning brush wheel 23 continuously brushes the surface of the ice-crushing front wheel 14 to remove the snow and ice chips adhering thereto, and prevent the accumulation from affecting the crushing effect. In order to further enhance the cleaning effect and prevent the wheel surface from freezing, the ice-crushing wheel flushing mechanism 3 is started intermittently, and the liquid pump 32 draws de-icing liquid from the de-icing liquid storage tank 31 and transports it to the flow equalizing plate 33. The liquid is sprayed onto the surface of the ice-crushing front wheel 14 and the ground area in front after the crushing process through the multiple groups of atomizing nozzles 34 thereon, so as to flush the residual crushed ice and assist in melting. Step 3: After the ice layer has been broken, preliminarily cleaned, and passed through the area sprayed with de-icing fluid, the de-icing agent dispensing mechanism 4 begins operation. Its third drive motor 46 drives the lower turntable 47 to rotate. When the lower discharge hole 48 on the lower turntable 47 overlaps with the upper discharge hole 45 at the bottom of the de-icing agent storage hopper 43, the de-icing agent particles fall into the guide tube 44 through the overlapping holes under the action of gravity and are finally spread on the treated clean road surface. By controlling the speed of the third drive motor 46 and adjusting the rate and timing of the hole overlap, the intermittent de-icing agent dispensing amount and frequency can be precisely controlled, thereby effectively preventing the re-freezing of road surface water or the rapid freezing of newly fallen snow. Step 4. During the entire operation of the device, if the road surface is uneven and causes the ice-crushing guide push plate 19 to be subjected to an upward force, the guide rod 18 will slide upward along the guide through hole 16 on the support beam 15, compressing the support spring 110, allowing the push plate to be lifted briefly. After passing the unevenness, the support spring 110 releases the elastic force, pushing the guide rod 18 and the ice-crushing guide push plate 19 to reset, so that they are close to the ground again, ensuring the continued effectiveness and adaptability of the ice pushing operation.

[0033] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.

10. A method for using a deicing device for road and bridge maintenance, using the deicing device for road and bridge maintenance according to any one of claims 1 to 9, characterized in that: include: Step 1: After the device is started, the first drive motor (12) is operated, and the gear and chain on the rotating shaft drive the ice crushing front wheel (14) to rotate, pushing the device forward, and the ice crushing front wheel (14) crushes and breaks the ice layer on the surface of the road bridge. At the same time, during the movement of the device, the ice crushing guide push plate (19) is kept in close contact with the ground under the elastic action of the support spring (110), and the ice and snow fragments crushed by the ice crushing front wheel (14) are steadily pushed to both sides of the road along its inclined surface, completing the preliminary cleaning; Step 2: while the ice crushing front wheel (14) is working, the second drive motor (22) of the ice crushing wheel cleaning mechanism (2) is started, and all the cleaning brush wheels (23) are driven to rotate synchronously through the chain and the transmission gear. The brush wrapped on the outside of the cleaning brush wheel (23) continuously brushes the surface of the ice crushing front wheel (14) to remove the snow and ice debris adhering thereto, and prevent the accumulation from affecting the crushing effect. In order to further enhance the cleaning effect and prevent the wheel surface from freezing, the ice crushing wheel flushing mechanism (3) is started intermittently, and the liquid pump (32) draws deicing liquid from the deicing liquid storage tank (31) and transports it to the flow equalizing plate (33), and sprays it onto the surface of the ice crushing front wheel (14) and the ground area in front after the crushing process through the plurality of groups of atomizing nozzles (34) thereon, so as to flush the residual crushed ice and assist in melting; Step 3: After the ice layer is broken, preliminarily cleaned and passes through the area sprayed with de-icing liquid, the de-icing agent delivery mechanism (4) operates, and its third drive motor (46) drives the lower turntable (47) to rotate. When the lower discharge hole (48) on the lower turntable (47) coincides with the upper discharge hole (45) at the bottom of the de-icing agent storage bucket (43), the de-icing agent particles fall into the guide tube (44) through the coincident hole under the action of gravity and are finally spread on the treated clean road surface. By controlling the speed of the third drive motor (46), the rate and timing of the hole coincidence are adjusted to achieve precise control of the intermittent de-icing agent spreading amount and frequency, thereby effectively preventing the road surface water from refreezing or the newly fallen snow from freezing quickly. Step 4: During the entire operation of the device, if the road surface is uneven and causes the ice-crushing guide push plate (19) to be subjected to an upward force, the guide rod (18) will slide upward along the guide through hole (16) on the support beam (15), compressing the support spring (110) and allowing the push plate to be temporarily lifted. After the unevenness is passed, the support spring (110) releases the elastic force, pushing the guide rod (18) and the ice-crushing guide push plate (19) back to their original position, making them close to the ground again, thereby ensuring the continued effectiveness and adaptability of the ice-pushing operation.
