Description

[Technical Field]

[0001] This invention relates to the technical field of road repair equipment, and in particular to the technical field of a road repair device. [Background Technology]

[0002] With the rapid development of highway construction, asphalt pavement, due to its advantages such as good permeability and high structural strength, has become a commonly used pavement material for urban roads and expressways. As asphalt pavement becomes more widespread, its maintenance has become an important part of road maintenance work.

[0003] After prolonged use, asphalt pavements develop potholes, severely affecting their smoothness and driving safety. Without timely repair, this damage will worsen, expanding the affected area and shortening the pavement's lifespan. Repair is necessary. Currently, when using repair equipment to fix potholes on asphalt roads, repair material is typically added to the pothole. The equipment's rollers then roll back and forth over the pothole, compacting the material for repair. Since the amount of repair material added and the size of the pothole are determined by the operator's experience, the principle is generally to add more material than necessary. Insufficient material prevents the rollers from detaching from the original pavement, resulting in insufficient compaction and a shorter repair lifespan. Conversely, excessive material allows the rollers to detach from the pavement, ensuring proper compaction and extending the repair lifespan. This explains why small repairs often result in a slightly higher surface area than the original pavement, affecting driving comfort and wasting material. [Summary of the Invention]

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a road surface repair device that can improve the smoothness of the repaired road surface compared with the original road surface, improve driving comfort, and save raw materials.

The paving mechanism includes a support mechanism, and a material conveying mechanism is provided on the support mechanism. A flattening mechanism is provided below the output end of the material conveying mechanism.

When the screw I is rotated clockwise or counterclockwise, the two nuts I move towards each other or in opposite directions.

[0011] Preferably, the tiling mechanism includes two side plates, a front baffle, a rear baffle, several rollers, and a mounting mechanism.

[0032] Working process of this invention:

[0033] In the operation of this road repair device, the starter motor 222 drives the milling drum 223 to rotate and mill the damaged potholes on the road surface. The servo cylinder III 214 drives the mounting base 216 to rise and fall, which in turn drives the milling mechanism 22 to rise and fall, thus controlling and adjusting the depth of the milled potholes. The servo cylinder I53 drives the slide I52 to move back and forth, which in turn drives the road milling mechanism 2 to move back and forth, thus controlling and adjusting the milling amount in the forward and backward direction (the length direction of the milled pothole). The servo cylinder II 211 drives the slide II 213 to move left and right, which in turn drives the milling mechanism 22 to move, achieving... The milling amount of the road milling mechanism 2 in the left-right direction (milling pit width direction) is controlled and adjusted. After the pit is milled into the required rectangular shape, the motor 222 stops working, and the road milling mechanism 2 returns to the starting position. Then, the milled pit and its surrounding surface are cleaned manually. Then, the manual linear module II 302 is operated manually to drive the paving mechanism 32 to move left-right for position adjustment, so that the paving mechanism 32 corresponds to the milled pit. Then, the servo cylinder I53 drives the slide I52 to move forward, so that the paving mechanism 32 enters the front end above the milled pit. Then, the manual linear module I301 is operated manually to drive the paving mechanism 32 to move downward, so that the roller 32 4. Place the material on the original road surface, then start the linear vibrating feeder 312 to pour a certain amount of repair material into the hopper 311. The repair material in the hopper 311 falls from its output end into the conveying trough 3121 of the linear vibrating feeder 312. Under the action of vibration, it is dispersed and conveyed, and finally output from the output end of the conveying trough 3121. The repair material output from the conveying trough 3121 falls into the pit between the baffle frame formed by the two side plates 321, the front baffle 322 and the rear baffle 323. When the amount of repair material accumulated enters the baffle frame and exceeds the lower end of the telescopic plate 3223, the servo cylinder I53 is activated to drive the slide I52 to move backward. The paving mechanism 32 is slowly moved backward, and the telescopic plate 3223 scrapes the repair material to flatten it and lays it flat in the pit. After the material is laid, the linear vibrating feeder 312 stops working. The manual linear module I301 is manually operated to drive the paving mechanism 32 to move upward. Then, the servo cylinder IV43 is started to drive the corresponding swing arm 42 to rotate downward. The swing arm 42 drives the pressure roller 44 to press it on the original road surface. Then, the tractor is started to drive the road repair device to move back and forth. The pressure roller 44 rolls the laid repair material to compact it. After compaction is completed, the servo cylinder IV43 is started to drive the swing arm 42 to drive the pressure roller 44 back to the starting position.

[0034] Loosen the hand-tightening bolt 3226, and then adjust the height of the telescopic plate 3223 as needed. After the adjustment is completed, tighten the hand-tightening bolt 3226 to control and adjust the height of the laid repair material above the original road surface.

[0035] Rotating screw II326 clockwise or counterclockwise causes the two nuts II328 to move in opposite directions or towards each other. The two nuts II328 drive the corresponding side plates 321 to slide, which can be adjusted according to the width of the groove.

[0036] Rotating the screw I3133 clockwise or counterclockwise causes the two nuts I3132 to move toward or in opposite directions. The two nuts I3132 drive the corresponding baffles 3131 to rotate, so that the distance between the free ends of the two baffles 3131 can be adjusted according to the width of the groove.

[0037] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
