Description

Technical Field

[0001] This utility model relates to the technical field of road surface repair auxiliary devices, specifically a road pothole repair device. Background Technology

[0002] With the rapid development of infrastructure construction in my country, public facilities are becoming more and more complete. Highway construction is the foundation of all construction, and the total length of highways in the country is also increasing day by day. Moreover, due to the aging of highways and the damage to the road surface caused by overloaded vehicles, potholes inevitably appear on the highways and need to be repaired.

[0003] Currently, when repairing potholes on the road, after cleaning the potholes and filling them with new repair material, the filling material needs to be leveled to make it flush with the original road surface, ensuring the comfort and safe passage of passing vehicles.

[0004] A search revealed a utility model patent in China with patent publication number CN222435020U, which discloses a road pothole repair device. The device is roughly described as including a rolling device and a hammering device connected to a vehicle frame. The hammering device includes a gantry frame fixedly connected to the vehicle frame, on which a lifting device electrically connected to a battery is mounted. During use, when the reciprocating screw of the lifting device rotates and drives the lifting plate upwards, the lifting plate, in conjunction with an electromagnet and armature, will drive the sleeve, pressure rod, and pressure plate, among other related components, upwards until the lifting plate reaches its highest point. At this point, the rubber pad contacts a pressure switch, triggering the switch. The pressure switch, when triggered, de-energizes the electromagnet, causing it to lose its magnetism. The armature then separates from the electromagnet, allowing the sleeve, pressure rod, and pressure plate to fall freely. The pressure plate then hammers downwards, leveling the material filling the dent without requiring adjustment of the pressure plate height to ensure the material isn't too high. While convenient, this device has some drawbacks. For example, it's difficult to shield the material as it impacts, causing it to scatter and potentially pollute or harm the surrounding environment and workers. Therefore, we propose a highway dent repair device. Utility Model Content

Multiple springs 1 are installed between the slider 11 and the sliding groove 10. A pressure plate 12 is detachably connected to the slider 11. The telescopic cylinders 9 are used to drive the sliding groove 10 and slider 11 to rise and fall, allowing the pressure plate 12 to level the newly repaired material. The springs 1 act as a buffer. The motor 5, threaded shaft 6, etc., are used to drive the movable plate 8 and pressure plate 12 to move, ensuring the pressure plate 12 performs a thorough leveling.

[0033] Two slots are provided on the slider 11, and two blocks 13 are fixedly connected to the pressure plate 12. The blocks 13 are adapted to the slots. A second slide groove is provided in the slot, and a second slider 14 is slidably connected in the slide groove. A second spring is provided between the second slider 14 and the slide groove. A control block 15 is fixedly connected to the second slider 14. The control block 15 passes through the slide groove through the control port. A limit groove is provided on the block 13, and the second slider 14 is located in the limit groove, which is used to facilitate the disassembly and replacement of the pressure plate 12, making it convenient for people to carry out maintenance.

[0034] Multiple stabilizing grooves are provided on the slider 11. Multiple stabilizing shafts 16 are fixedly connected in the groove 10.

Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. Furthermore, the telescopic cylinder 2, telescopic cylinder 9, and motor 5 are equipped with matching control switches. The installation position of the control switches can be selected according to actual usage requirements to facilitate operation and control by the operator.

[0039] In summary, the working principle and process of this road pothole repair device are as follows: First, place the device at the desired location and connect the motor 5 to the forward and reverse circuits according to the instruction manual. Then, when repairing potholes, first fill the area to be repaired with new repair material. Next, move the entire device so that the base 1 and the shielding frame 4 are above the repair position. Rotate and remove the lower limit rod 19, moving it out of the limit hole. Activate the telescopic cylinder 2, which lowers the shielding frame 4 to lock onto the repair position. Then, thread the limit rod 19 onto the support cylinder 17, allowing the limit plate to enter another limit hole for positioning. Finally, activate the motor 5 and the telescopic cylinder 9. The motor 5 will drive the threaded shaft... Rotating the threaded shaft 6 causes the moving block to slide on the two fixed shafts 7, thus allowing the pressure plate 12 to move within the shielding frame 4. The telescopic cylinder 9 causes the slide groove 10 and slider 11 to descend, making the pressure plate 12 fill the pits of the new repair material evenly. During this process, the spring 1 plays a role in avoiding rigid impact and providing buffer protection, which can ensure and improve the service life of each component. The shielding frame 4 can ensure the safety of the environment and people by preventing material from splashing. When it is necessary to maintain and disassemble the pressure plate 12, people can open the maintenance plate 20 and use the hand to slide the control block 15 to move the slider 14. The slider 14 compresses the spring 2, and the slider 14 can move out of the limit groove. In this way, people can remove the clip 13 and the pressure plate 12 for maintenance or replacement.

[0040] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
