Description

Technical Field

[0001] This utility model belongs to the technical field of asphalt pavement surface layer disease maintenance, and relates to a hot recycling maintenance vehicle, specifically a road hot recycling maintenance vehicle integrating multiple tools. Background Technology

[0002] Depending on the repair process, commonly used methods for repairing asphalt pavement surface defects include four types: patching, filling, spraying, and hot recycling. Patching is complex, requires many operators, and is expensive; filling is a temporary method for repairing potholes; spraying has poor durability; in contrast, hot recycling allows for the on-site recycling of old materials, reducing resource waste and providing reliable and durable repairs.

[0003] The existing hot recycling maintenance process for asphalt pavements mainly includes several stages: removal of old materials from the damaged area, loading of old materials, heating and recycling, laying of new mixture, and leveling and compaction. However, the automation level of existing equipment during hot recycling repair operations is not high. For example, demolition of damaged areas mainly relies on manual hand-held pneumatic picks, recycling of old materials mainly relies on manual hand-held shovels, and compaction of the new mixture also relies on manual hand-held plate compactors. The entire repair process suffers from excessive manual labor and inadequate execution of the process flow.

[0004] In summary, there is an urgent need for a hot recycling maintenance equipment capable of mechanized construction throughout the entire process. However, the challenge lies in the significant differences between the various construction stages within the process, making it difficult to meet all process requirements with a single tooling. Therefore, designing a road surface hot recycling maintenance vehicle that integrates multiple tools is a pressing issue that needs to be addressed in the field of road surface distress maintenance. Summary of the Invention

[0068] In this embodiment, the working process of the road surface hot recycling maintenance vehicle integrating multiple tools is as follows:

[0069] After the repair personnel drive the multi-tool road hot recycling maintenance vehicle close to the damaged area, they slowly move the vehicle so that the cab passes the damaged area and the damaged area is within the working range of the robotic arm assembly 4 mounted at the rear of the vehicle. The repair personnel then disembark to set up traffic warning signs and control the robotic arm assembly 4 from the rear of the vehicle using buttons and handles on a handheld control panel to complete the entire repair process.

[0070] Step 1: Use cutting fixture 10 to cut out a rectangular area around the diseased area, which is referred to as the cutting process.

[0071] Step 2: Use crushing equipment 13 to remove the old material in the rectangular defect area, which is referred to as the crushing process.

[0072] Step 3: Use the material collection tool 11 to collect the broken and dismantled old materials within the rectangular area; this is referred to as the material collection process.

[0073] Step 4: Use the feeding fixture 10 to evenly feed the new mixture into the rectangular area after the old material has been removed; this is referred to as the feeding process.

[0074] Step 5: Use compaction tool 14 to iron and compact the new mixture within the rectangular defect area, referred to as the compaction process.

[0075] Specifically, in step one, the hydraulic wrist 404 is accurately delivered to the cutting fixture 12 mounted on the cutting fixture support device 5 by controlling the planar rotating component 401, the upper arm 402, and the lower arm 403 of the robotic arm assembly 4. Then, the hydraulic wrist 404 grips the front support rod 1205 and the rear support rod 1206 of the cutting fixture 12. After the hydraulic wrist 404 firmly grips the cutting fixture 12, the robotic arm assembly 4, through the planar rotating component 401, the upper arm 402, the lower arm 403, and the hydraulic wrist 404, can move the cutting fixture 12 to any position in the damaged area, pressing the saw blade 1204 firmly onto the road surface and performing rolling cuts along a specific route, ultimately cutting out a rectangular area. After the cutting process is completed, the robotic arm assembly 4 returns the cutting fixture 12 to the cutting fixture support device 5.

[0076] Specifically, in step two, the hydraulic wrist 404 is accurately delivered to the crushing fixture 13 mounted on the crushing fixture support device 6 by controlling the planar rotating component 401, the upper arm 402, and the lower arm 403 of the robotic arm assembly 4. Then, the hydraulic wrist 404 grasps the quick-change head 15 on the crushing fixture 13, specifically the front support rod 1505 and the rear support rod 1506 of the quick-change head. After the hydraulic wrist 404 firmly grasps the crushing fixture 13, the robotic arm assembly 4, through the planar rotating component 401, the upper arm 402, the lower arm 403, and the hydraulic wrist 404, can move the crushing fixture 13 to any position within the rectangular defect area cut in step one. Utilizing the vibration and impact of the crushing blade 1302, it crushes along a specific route, ultimately removing the old material within the rectangular defect area. After the crushing process is completed, the robotic arm assembly 4 returns the crushing fixture 13 to the crushing fixture support device 6.

[0077] Specifically, in step three, the hydraulic wrist 404 is accurately delivered to the receiving fixture 11 mounted on the receiving fixture support device 9 by controlling the planar rotating component 401, the upper arm 402, and the lower arm 403 of the robotic arm assembly 4. Then, the hydraulic wrist 404 is controlled to grab the quick-change head 15 on the receiving fixture 11, specifically grabbing the front support rod 1505 and the rear support rod 1506 of the quick-change head. After the hydraulic wrist 404 firmly grabs the receiving fixture 11, the robotic arm assembly 4 can drive the receiving fixture 11 to any position in the rectangular damaged area of ​​the crushed old material in step two through the planar rotating component 401, the upper arm 402, the lower arm 403, and the hydraulic wrist 404. Then, the bottom surface of the receiving fixture 11 is pressed against the ground. Under the rotation of the scraping teeth 110203 of the scraping assembly 1102, the broken old material is scraped onto the belt 110303. Under the rotation of the belt 110303, the old material is sent to the storage box shell 110103. Next, by controlling the robotic arm assembly 4, the receiving fixture 11 is tilted at 45 degrees and sent to the inlet 302 of the hot recycling box of the hot recycling assembly 3. By controlling the unloading switch motor 1104 to drive the differential 1105 with differential lock, the cable on the cable shaft 1106 is loosened, and the unloading plate 11010303 rotates and opens under the action of gravity around the unloading plate ear plate 11010302, dumping the collected waste material into the hot recycling box 301 of the hot recycling assembly 3 for heating and recycling. Finally, after the entire material receiving process is completed, the material receiving fixture 11 is returned to the material receiving fixture support device 8 via the robotic arm assembly 4.

[0078] Specifically, in step four, the hydraulic wrist 404 is accurately delivered to the feeding fixture 10 mounted on the feeding fixture support device 8 by controlling the planar rotating component 401, the upper arm 402, and the lower arm 403 of the robotic arm assembly 4. Then, the hydraulic wrist 404 is controlled to grab the quick-change head 15 on the feeding fixture 10, specifically grabbing the front support rod 1505 and the rear support rod 1506 of the quick-change head. After the hydraulic wrist 404 firmly grabs the feeding fixture 10, the robotic arm assembly 4 can drive the feeding fixture 10 to move through the planar rotating component 401, the upper arm 402, the lower arm 403, and the hydraulic wrist 404, aligning the feeding fixture inlet 1002 of the feeding fixture 10 with the trapezoidal outlet 303 of the heat recycling box of the heat recycling assembly 3 to receive the heat repair material. After the hot repair material is received, the unloading baffle 1007 opens under the pull of the first hydraulic cylinder 1006, and the hot repair material in the screw feeder 1003 is then pushed to the unloading port 1005 for unloading by the screw feeder 1004. Then, the feeding fixture 10, driven by the robotic arm assembly 4, evenly delivers the hot repair material along a specific trajectory to the rectangular defect area after the old material was collected in step three. Finally, after the entire feeding process is completed, the robotic arm assembly 4 returns the feeding fixture 10 to the feeding fixture support device 8.

[0079] Specifically, in step five, the hydraulic wrist 404 is accurately delivered to the compaction fixture 14 resting on the compaction fixture support device 7 by controlling the planar rotating component 401, the upper arm 402, and the lower arm 403 of the robotic arm assembly 4. Then, the hydraulic wrist 404 is controlled to grab the quick-change head 15 on the compaction fixture 14, specifically grabbing the front support rod 1505 and the rear support rod 1506 of the quick-change head. After the hydraulic wrist 404 firmly grabs the compaction fixture 14, the robotic arm assembly 4 can drive the compaction fixture 14 to any position in the rectangular defect area after feeding in step four, pressing along a specific trajectory to complete the compaction process. The compaction process includes two stages: ironing and compaction. In the ironing stage, the compaction side plate 1404 unfolds to a flat surface around the hinge plate 1403 under the action of the second hydraulic cylinder 1405, ironing the heat repair material flat. In the compaction stage, the compaction side plate 1404 closes around the hinge plate 1403 under the action of the second hydraulic cylinder 1405, and compaction is performed using a standard compaction device. Finally, after the entire compaction process is completed, the compaction fixture 14 is returned to the compaction fixture support device 7 via the robotic arm assembly 4.

[0080] After completing the above five steps, the repair personnel can drive the integrated multi-tool road hot recycling maintenance vehicle to the next defect area to carry out repair work.
