[0037] like Figure 1 , Figure 2 As shown, the present invention provides a system for maintaining highway pavement, comprising:

[0038] A collection unit, detachably mounted at the front of the vehicle, comprising:

[0039] The first housing 4 is detachably connected to the front end of the vehicle, and the bottom of the first housing 4 is provided with multiple wheels 7;

[0040] Collection box 17 is located at the rear of the first housing 4;

[0041] The transport component has its bottom in contact with the road surface and its top connected to the top of the collection box 17;

[0042] An ice-breaking section, detachably disposed at the front end of the collecting section, the ice-breaking section comprising:

[0043] The second housing 1 is detachably connected to the head of the first housing 4;

[0044] Multiple icebreaker cones 8 are raised and lowered in front of the transport assembly and continuously inserted into or extended into the second housing 1;

[0045] Multiple ice-breaking needles 28 are raised and lowered between the ice-breaking cone 8 and the transport assembly and are continuously inserted into or extended from the second housing 1.

[0046] The system for maintaining highway pavement provided by this technical solution mainly consists of a transport vehicle, a collection unit detachably mounted at the front of the vehicle, and an ice-breaking unit detachably mounted at the front of the collection unit. The collection unit includes a first housing 4 detachably connected to the front of the vehicle, a collection box 17 located at the rear of the first housing 4, and a transport component for ice blocks. The ice-breaking unit includes a second housing 1 detachably connected to the front of the second housing 1, multiple ice-breaking cones 8 raised and lowered in front of the transport component, and multiple ice-breaking needles 28 raised and lowered between the ice-breaking cones 8 and the transport component. During the raising and lowering process, the ice-breaking cones 8 and ice-breaking needles 28 continuously insert into or extend from the second housing 1 to strike and break the ice on the road surface. The ice-breaking cones 8 perform the first breaking, and the ice-breaking needles 28 perform the second breaking. The bottom of the transport component contacts the road surface, and the top communicates with the top of the collection box 17 to transport the ice blocks on the road surface to the collection box 17. The bottom of the first housing 4 is provided with multiple wheels 7 to facilitate the movement of the collection unit.

[0047] The working process of the system for maintaining highway pavement provided by this technical solution is as follows: the movement of the vehicle directly or indirectly drives the collection unit and the ice breaking unit to move forward continuously. At the same time, the ice breaking cone 8 and the ice breaking needle 28 rise and fall continuously, breaking the ice on the road surface first and second time in sequence. The transport component continuously transports the broken ice blocks on the road surface to the collection box 17 for collection.

[0048] The present invention includes at least the following beneficial effects: the first housing 4 of the collection unit is detachably connected to the front end of the vehicle, and a collection box 17 is provided at the rear of the first housing 4. The bottom of the transport component of the collection unit is in contact with the road surface, and the top is connected to the top of the collection box 17. The second housing 1 of the ice-breaking unit is detachably connected to the head of the first housing 4. The ice-breaking needle 28 and ice-breaking cone 8 of the ice-breaking unit are sequentially raised and lowered in front of the transport component and continuously inserted into or extended into the second housing 1. During the vehicle's forward movement, the ice-breaking cone 8 and ice-breaking needle 28 strike the ice surface on the road surface in sequence, breaking the ice surface once and then twice. The ice-breaking process does not require manual striking, reducing manual labor. Moreover, multiple ice-breaking cones 8 and multiple ice-breaking needles 28 strike the ice multiple times simultaneously, resulting in a larger ice-breaking area and more thorough ice breaking, greatly improving ice-breaking efficiency. The second housing 1 is detachably connected to the first housing 4 and the vehicle, facilitating disassembly and assembly, and allowing for independent use of the vehicle and the collection unit.

[0049] In another technical solution, such as Figure 1 , Figure 2As shown, in the system for maintaining highway pavement, a horizontal first rotating shaft 12 is rotatably mounted inside the second housing 1. A first helical gear is mounted on the first rotating shaft 12. The second housing 1 also contains a support frame 13 and a pair of horizontal support plates 34. A vertical drive shaft 14 is rotatably mounted on the support frame 13. A drive gear 15 and a second helical gear 16 meshing with the first helical gear are mounted on the drive shaft 14. Part of the drive gear 15 has no teeth on its outer circumference. A vertical drive shaft 14 is rotatably mounted on the support plates 34. A straight support cylinder 33 is fitted with a driven gear 35 that meshes with the drive gear 15. A lifting screw 32 is movably inserted into the support cylinder 33 via a threaded structure. A horizontal lifting plate 31 is provided at the bottom of the lifting screw 32. The ice-breaking cone 8 or the ice-breaking needle 28 is provided at the bottom of the lifting plate 31. Two pairs of vertical limiting grooves 30 are provided on the inner wall of the second housing 1, corresponding to the two ends of a pair of support plates 34. The ends of the support plates 34 are movably inserted into their corresponding limiting grooves 30. A first rotating shaft 12 is rotatably mounted on the second housing 1 via a bearing structure. A drive shaft 14 is rotatably mounted on a support frame 13 via a bearing structure. The support cylinder 33 is rotatably mounted on the support plate 34 via a bearing structure. The first rotating shaft 12 can be driven to rotate by a drive motor on the second housing 1. The power source for the drive motor can be a mobile power source from the vehicle or a fixed power source for wiring, depending on the actual situation. The drive motor drives the first rotating shaft 12 to rotate, which in turn drives the first helical gear to rotate, thereby driving the second helical gear 16, the drive shaft 14, and the drive gear 15 to rotate. When the teeth of the drive gear 15 mesh with one of the driven gears 35 and drive that driven gear 35 to rotate, the other driven gear 35 disengages from the teeth of the drive gear 15. The support cylinder 33 corresponding to the driven gear 35 rotates, and under the restriction of the limiting slide groove 30, the lifting screw 32 corresponding to the driven gear 35 drives its corresponding lifting plate 31 to rise. At the same time, the lifting screw 32 corresponding to the other driven gear 35... The lifting plate 31 descends continuously under its own weight, striking the ice surface. The ice-breaking cone 8 and ice-breaking needle 28 are driven by their respective corresponding lifting plates 31, which alternately rise and fall, further breaking the ice surface or ice blocks, making the ice blocks more thoroughly broken and facilitating collection and transportation. The outer half of the drive gear 15 is equipped with gears and the other half is gearless, and it is located between two driven gears 35. When the drive gear 15 meshes with one of the driven gears 35, it disengages from the other driven gear 35, causing the two driven gears 35 to rotate alternately, thereby causing the two lifting plates 31 to rise and fall alternately. The limiting groove 30 prevents the lifting plate 31 from rotating with the lifting screw 32.

[0050] In another technical solution, such as Figure 1 , Figure 2 As shown, in the system for maintaining highway pavement, the transport component includes:

[0051] An ice scraper 24 is inclinedly disposed at the bottom of the first housing 4, and the bottom end of the ice scraper 24 contacts the road surface.

[0052] The transport chamber 19 is vertically arranged at the front end of the collection box 17. A receiving groove 21 is provided at the bottom inlet of the transport chamber 19. The top outlet of the transport chamber 19 is connected to the top of the collection box 17. A vertical transport screw 20 is rotatably arranged inside the transport chamber 19.

[0053] A rotating conveyor belt 22 is inclined, with its bottom positioned below the top of the ice-shoveling plate 24 and its top positioned above the top opening of the receiving trough 21. A transport screw 20 is driven to rotate by a transport motor 6 at the top of the first housing 4. As the vehicle moves forward, the ice-shoveling plate 24 scoops up ice fragments, which move along the plate and fall onto the conveyor belt 22. The conveyor belt 22 then transports the ice fragments into the receiving trough 21, and from there into the transport chamber 19 through its bottom inlet. Finally, the conveyor screw 20 transports the ice fragments to the top outlet of the transport chamber 19, where they enter the collection box 17. The conveyor belt 22 accelerates the transport of the ice.

[0054] In another technical solution, such as Figure 1 , Figure 2 As shown, in the system for maintaining highway pavement, a second rotating shaft 25 parallel to the first rotating shaft 12 is rotatably mounted at the bottom of the first housing 4. Both the second rotating shaft 25 and the first rotating shaft 12 are equipped with first synchronous pulleys, which are connected by a first synchronous belt 27. Multiple ice-turning plates 26, all perpendicular to the second rotating shaft 25, are mounted on the second rotating shaft 25. When the ice-turning plates 26 rotate around the second rotating shaft 25, they can slide tangentially with the upper surface of the ice-shoveling plate 24. Under the action of the first synchronous belt 27, the rotation of the first rotating shaft 12 drives the rotation of the second rotating shaft 25, which in turn drives each ice-turning plate 26 to rotate obliquely upwards along the ice-shoveling plate 24, further propelling the ice block rapidly upwards along the ice-shoveling plate 24.

[0055] In another technical solution, such as Figure 1 , Figure 2 As shown, in the system for maintaining highway pavement, a pair of rotating rollers 23 are rotatably mounted inside the first housing 4. The conveyor belt 22 is fitted onto the pair of rotating rollers 23. A second synchronous pulley is mounted on both the rotating roller 23 near the second rotating shaft 25 and the second rotating shaft 25. The two second synchronous pulleys are connected by a second synchronous belt. The rotating rollers 23 can be rotatably connected to the first housing 4 via a bearing structure. Under the connection of the second synchronous belt, the rotating roller 23 near the second rotating shaft 25 rotates synchronously with the second rotating shaft 25, thereby driving the conveyor belt 22 to rotate.

[0056] In another technical solution, such as Figure 1 , Figure 2 , Figure 3 As shown, in the system for maintaining highway pavement, the second rotating shaft 25 includes a horizontal shaft one and a horizontal shaft two rotatably mounted on the first housing 4. The first shaft one is provided with a first synchronous pulley. The first shaft one and the second shaft two are provided with opposing non-circular cavities. Connecting shafts with the same cross-sectional dimensions are movably inserted into the two cavities to connect the first shaft one and the second shaft two. The first synchronous pulley on the second rotating shaft 25 is composed of a connecting half-wheel 40 and a movable half-wheel 36. The connecting half-wheel 40 is sleeved on the second rotating shaft 25. The connecting half-wheel 40 is provided with a connecting groove 39 that is open at the top and one side. The movable half-wheel 36 is provided with a connecting plate 37. The connecting plate 37 is movably inserted into the connecting groove 39 and is connected and locked to the groove wall of the connecting groove 39 by a first screw 38. The first housing 4 is provided with an operation window for operating and installing the first synchronous pulley. The first screw 38 is removed, and the moving half-wheel 36 is moved to separate it from the connecting half-wheel 40. At this time, the first synchronous belt 27 is loosened. The first synchronous belt 27 is removed from the connecting half-wheel 40, and then the connecting shaft is moved so that one end is detached from shaft one. At this time, shaft one and shaft two are separated, that is, the second rotating shaft 25 is disconnected. Then, the first synchronous belt 27 is removed from the second rotating shaft 25, and the ice-breaking part is removed, allowing the collection part to be used independently, such as for snow shoveling. This structure facilitates the disassembly and assembly of the first synchronous belt 27. The non-circular cavity prevents relative rotation between the connecting shaft and shaft one and shaft two. The connecting groove 39 prevents excessive movement of the moving half-wheel 36 during installation.

[0057] In another technical solution, such as Figure 1 , Figure 2 As shown, in the system for maintaining highway pavement, a salt water storage tank 10 is located in front of the ice-breaking cone 8 on the second housing 1. Multiple spray nozzles 9 are located at the bottom of the storage tank 10. The top of the storage tank 10 is connected to the outlet at the bottom of the collection tank 17 via a delivery pipe. The salt water accelerates the melting of ice, facilitating de-icing of the road surface. After the salt water enters the collection tank 17 with the ice, the melted salt water flows from the outlet at the bottom of the collection tank 17 through the delivery pipe back into the storage tank 10 for secondary use. A filter screen is installed at the outlet to filter impurities.

[0058] In another technical solution, such as Figure 2As shown, in the system for maintaining highway pavement, the collection box 17 has a support frame inside, and a collection trough 18 with an open top rests on the support frame. The collection trough 18 has multiple drainage holes at its bottom and is lower than the top outlet of the transport chamber 19. Ice blocks enter the collection trough 18 of the collection box 17 from the top outlet of the transport chamber 19. Some of the ice melts into water, which is then retained in the collection box 17 through the drainage holes for recycling. When the collection trough 18 is full of ice blocks, it can be removed from the support frame inside the collection box 17 to replace it with an empty collection trough 18.

[0059] In another technical solution, in the system for maintaining highway pavement, the top of the storage tank is open and equipped with an openable cover. Inside the storage tank is a trough for holding salt particles, with a leakage hole at the bottom. The top of the trough is connected to the infusion pipeline. The trough is used to replenish salt, maintaining a certain concentration of brine.

[0060] In another technical solution, such as Figure 1 As shown, in the system for maintaining highway pavement, the infusion pipeline includes:

[0061] The first pipe 5 is disposed on the first housing 4, and one end of the first pipe 5 is connected to the liquid outlet at the bottom of the collection box 17.

[0062] The second pipe 11 is disposed on the second housing 1. One end of the second pipe 11 is connected to the top of the feed trough, and the other end is inserted into the other end of the first pipe 5. A sealing membrane is provided between the pipe walls of the first pipe 5 and the second pipe 11 to prevent water leakage. Inserting or removing the first pipe 5 and the second pipe 11 can connect or disconnect the infusion pipeline.

[0063] In another technical solution, such as Figure 1 As shown, in the system for maintaining highway pavement, the first housing 4 is provided with a connecting block 3, which has multiple horizontal connecting holes. The second housing 1 is provided with multiple horizontal connecting rods. Each connecting rod is inserted into its corresponding connecting hole and fixed by a second screw 2. The second screw 2 is inserted into the threaded holes corresponding to the connecting block 3 and the connecting rod to connect and fix them, making disassembly and assembly convenient.

[0064] The present invention also provides a road surface maintenance method, which adopts the system for maintaining highway road surfaces described in any of the above technical solutions, and includes the following steps:

[0065] Step 1: Install the collection unit at the front of the vehicle, then install the ice-breaking unit at the front of the collection unit, and then move the vehicle to the road maintenance and de-icing location.

[0066] Step 2: The ice-breaking cone 8 and ice-breaking needle 28 intermittently rise and fall to strike the ice surface on the road, breaking it into ice blocks. At the same time, the transport component continuously transports the ice blocks from the road surface to the collection box 17 for collection.

[0067] The following embodiments are provided for the system and method for maintaining highway pavements according to the present invention:

[0068] A road maintenance method employing a system for maintaining highway pavements includes the following steps:

[0069] Step 1: Connect the first housing 4 of the collection unit to the front end of the vehicle. Then, insert the connecting rod on the second housing 1 of the ice-breaking unit into its corresponding connecting hole. At the same time, insert the other end of the first pipe 5 into the second pipe 11. Install the second screw 2 to lock the connecting rod and the connecting block 3. Through the operation window on the first housing 4, splice the moving half wheel 36 and the connecting half wheel 40 into the first synchronous wheel. Then, put the first synchronous belt 27 on the first synchronous wheel. Then, move the connecting shaft so that both ends are inserted into the cavities of shaft one and shaft two to connect shaft one and shaft two. Then, move the vehicle to the road maintenance and de-icing position and fill the liquid storage tank 10 with salt water.

[0070] Step 2: The vehicle moves forward and the drive motor is started, driving the first rotating shaft 12 to rotate, indirectly causing the ice-breaking needle 28 to rise. At the same time, the ice-breaking cone 8 falls under its own weight to break the ice surface once, or indirectly causes the ice-breaking cone 8 to rise, while the ice-breaking needle 28 falls under its own weight to break the ice surface a second time. The rotation of the first rotating shaft 12 directly or indirectly drives the second rotating shaft 25 and the rotating roller 23 to rotate, causing the ice-turning plate 26 to rotate around the second rotating shaft 25 and continuously push the ice blocks onto the ice-shoveling plate 24, and move them onto the conveyor belt 22. The rotating conveyor belt 22 transports the ice blocks into the receiving trough 21 and into the transport screw 20. Then, the transport motor 6 is started to drive the transport screw 20 to rotate, continuously transporting the ice blocks at the bottom of the transport chamber 19 to the top outlet of the transport chamber 19 and into the collection tank 18. When the collection tank 18 is full of ice blocks, it can be replaced. At the same time, the brine remains in the collection box 17 and enters the storage tank 10 through the conveying pipe for recycling, thus performing de-icing and maintenance on the road surface.

[0072] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
