Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and more specifically, to a pothole treatment device for highway maintenance. Background Technology

[0002] Potholes are a common problem affecting road performance and driving safety. If the potholes are not properly pre-treated before repair, the repair material will not adhere well to the original road surface, which will lead to premature damage to the repair area, recurrence of the problem, and increase the cost of road maintenance.

[0003] In existing technologies, the pretreatment of road potholes mainly relies on traditional cutting equipment for grooving operations. However, in actual operation, traditional equipment uses a single-axis cutting machine, which can only achieve cutting in one direction and cannot perform multi-angle, conformal cutting according to the actual shape of the pothole. This results in irregular, rough, and even uneven edges on the potholes. These irregular edges significantly reduce the effective bonding area between the repair material and the original road surface, seriously affecting the overall strength and service life of the repair layer. Based on the above problems, we propose a road maintenance pothole treatment device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a road maintenance pothole treatment device to solve the problem that the irregular groove edges of traditional treatment devices result in insufficient bonding area between the repair material and the original road surface, affecting the quality and life of pothole repair.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a road maintenance pothole treatment device, including a traveling component and a grinding component; the traveling component includes a traveling trolley, a slide is provided on one side of the traveling trolley, a lifting support plate that moves up and down along the slide is provided on the surface of the slide, a cylinder is provided in the middle of the slide, and the output end of the cylinder is connected to the lifting support plate; the grinding component includes a longitudinal displacement mechanism provided at the bottom of the lifting support plate, a transverse displacement mechanism provided at the bottom of the longitudinal displacement mechanism, a motor provided at the bottom of the transverse displacement mechanism, a rotating shaft provided at the bottom output end of the motor, a grinding head provided at the bottom of the rotating shaft, a beveled surface and a flat surface sequentially provided on the grinding head, a spiral groove continuously spirally wound around the outer periphery of the beveled surface and the top of the grinding head is provided with a material collection groove, and the material collection groove is connected to the top of the spiral groove; The diameter of the grinding head gradually decreases from top to bottom. When the grinding head contacts the side wall of the road pothole, the inclined part makes the edge of the pothole form a regular inclined surface, and when the flat part contacts the side wall of the road pothole, it makes the edge of the pothole form a regular horizontal surface, so that the cross-section of the pothole is a step shape that is narrow at the top and wide at the bottom.

[0006] Preferably, it also includes a waste collection assembly, which includes a collection box disposed on the top of the lifting pallet, a negative pressure pump disposed on one side of the collection box and connected to the collection box, a material conveying pipe disposed on the top of the collection box, a suction hood disposed on the surface of the rotating shaft, the suction hood being located above the grinding head, and the top of the suction hood being connected to the bottom of the material conveying pipe.

[0007] Preferably, the suction hood is connected to the rotating shaft via a rotating bushing, the conveying pipe is made of corrugated pipe, and the collection box and the lifting pallet are detachably connected.

[0008] Preferably, the lifting plate is provided with a slide block on the side near the slide frame, the surface of the slide frame is provided with a slide groove that mates with the slide block, and a pusher is provided on the top of the slide frame.

[0009] Preferably, the spiral direction of the spiral groove is adapted to the rotation direction of the grinding head body.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a grinding component with a grinding head that has a beveled surface and a flat surface in sequence, and the diameter of the grinding head gradually decreases from top to bottom. When the grinding head contacts the side wall of the pothole, the beveled surface forms a regular inclined surface at the edge of the pothole, and the flat surface forms a regular horizontal surface at the edge of the pothole. Ultimately, the pothole cross-section is stepped, narrower at the top and wider at the bottom, which greatly increases the bonding area between the repair material and the original road surface, effectively reducing the probability of peeling or falling off in the repaired area after the road is opened to traffic. At the same time, the grinding process can efficiently remove loose particles, burrs and irregular protrusions from the edge of the pothole, making the edge smoother and more regular, providing a flat interface for subsequent material filling, ensuring a smooth transition between the repair layer and the original road surface, and reducing stress concentration and early damage caused by uneven edges after the road is opened to traffic.

[0011] 2. This utility model also incorporates a waste collection component. By designing a spiral groove on the surface of the grinding head, when the grinding head rotates, the spiral groove can push the waste generated during grinding, such as asphalt debris and sand particles, upwards along the spiral trajectory through the spiral propulsion action. This achieves directional transportation and centralized cleaning of waste, preventing waste from accumulating in the pit and affecting subsequent repair work. At the same time, combined with the negative pressure adsorption of the waste collection component, the grinding waste can be efficiently transported upwards and collected centrally, preventing waste residue from affecting the repair quality and reducing pollution at the construction site.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments: This utility model relates to a road maintenance pothole treatment device, including a traveling component 1 and a grinding component 2. The traveling component 1 includes a traveling trolley 101, a slide 102 fixedly connected to one side of the traveling trolley 101, a lifting plate 103 slidably connected to the surface of the slide 102 and moving up and down along the slide 102, and a cylinder 104 fixedly connected to the middle of the slide 102, with the output end of the cylinder 104 connected to the lifting plate 103. The traveling trolley 101 is used to carry the device to move, realize the position adjustment of the equipment on the road, and facilitate alignment with different potholes. The slide 102 provides support and guide structure for the lifting plate 103 to move up and down. The lifting plate 103 is used to carry the grinding component 2 and the waste collection component 3. It is driven by the cylinder 104 to move up and down, adjust the insertion depth of the grinding head 205 to adapt to potholes of different depths, and the cylinder 104 provides power to drive the lifting plate 103 to move up and down along the slide 102 and control the lifting action of the grinding head 205.The grinding assembly 2 includes a longitudinal displacement mechanism 201 fixedly connected to the bottom of the lifting pallet 103. A transverse displacement mechanism 202 is fixedly connected to the bottom of the longitudinal displacement mechanism 201. A motor 203 is fixedly connected to the bottom of the transverse displacement mechanism 202. A rotating shaft 204 is fixedly connected to the bottom output end of the motor 203. A grinding head 205 is fixedly connected to the bottom of the rotating shaft 204. The grinding head 205 has a series of inclined surfaces 2051 and flat surfaces 2052. A spiral groove 2053 is continuously spirally wound around the outer periphery of the inclined surfaces 2051 and flat surfaces 2052. A material collection groove 2054 is formed at the top of the grinding head 205, and the material collection groove 2054 communicates with the top of the spiral groove 2053. Mechanism 201 is used to adjust the longitudinal horizontal position of the grinding assembly 2, so that the grinding head 205 is aligned with the longitudinal position of the pothole. Lateral displacement mechanism 202 is used to adjust the lateral horizontal position of the grinding assembly 2, so that the grinding head 205 is precisely aligned with the pothole. Motor 203 provides power to drive the rotating shaft 204 and grinding head 205 to rotate at high speed, realizing the grinding function. The rotating shaft 204 transmits the power of motor 203, driving the grinding head 205 to rotate. The grinding head 205 directly grinds the sidewall of the pothole, forming a regular stepped cross-section at the edge of the pothole. When the inclined surface 2051 contacts the sidewall of the pothole, it grinds the edge of the pothole on an inclined surface, forming a regular inclined edge, increasing the bonding area between the repair material and the original road surface. When the face part 2052 contacts the side wall of the pit, the edge of the pit is horizontally ground to form a regular horizontal edge. Combined with the beveled face part 2051, the pit cross-section is stepped, narrower at the top and wider at the bottom. The spiral groove 2053 is continuously spirally wound around the outer periphery of the beveled face part 2051 and the flat face part 2052. The rotational force of the grinding head 205 transports the grinding waste upwards along the groove to the collection trough 2054. The collection trough 2054 is connected to the top of the spiral groove 2053, collecting the waste transported by the spiral groove 2053, facilitating subsequent collection by the waste collection component 3. This utility model designs a grinding component 2 in which the grinding head 205 is sequentially provided with beveled face part 2051 and flat face part 2052. The diameter gradually decreases from top to bottom. When the grinding head 205 contacts the sidewall of the pothole, the inclined part 2051 creates a regular inclined surface at the edge of the pothole, while the flat part 2052 creates a regular horizontal surface at the edge of the pothole. Ultimately, this results in a stepped cross-section that is narrower at the top and wider at the bottom, significantly increasing the bonding area between the repair material and the original road surface. This effectively reduces the probability of peeling or detachment of the repaired area after traffic has resumed. Simultaneously, the grinding process efficiently removes loose particles, burrs, and irregular protrusions from the pothole edge, making the edge smoother and more regular. This provides a flat interface for subsequent material filling, ensuring a smooth transition between the repair layer and the original road surface, and reducing stress concentration and early damage caused by uneven edges after traffic has resumed.

[0015] Specifically, it also includes a waste collection assembly 3, which includes a collection box 301 snapped onto the top of the lifting pallet 103. A negative pressure pump 302 is fixedly connected to one side of the collection box 301 and is connected to the collection box 301. A conveying pipe 303 is inserted into the top of the collection box 301. A suction hood 304 is installed on the surface of the rotating shaft 204. The suction hood 304 is located above the grinding head 205, and its top is connected to the bottom of the conveying pipe 303. The collection box 301 is used to store grinding waste collected from the pit and is a waste storage container. The negative pressure pump 302 creates a negative pressure environment inside the collection box 301, providing suction to draw the waste from the suction hood 304 through the conveying pipe 303 into the collection box 301. The conveying pipe 303 connects the suction hood 304 and the collection box 301. As a waste conveying channel, the suction hood 304 is installed above the grinding head 205 to collect the waste discharged from the collection trough 2054. The waste is then guided into the conveying pipe 303 by the suction of the negative pressure pump 302. This utility model also designs a waste collection component 3, which has a spiral groove 2053 on the surface of the grinding head 205. When the grinding head 205 rotates, the spiral groove 2053 can push the waste generated by grinding, such as asphalt debris and sand particles, upward along the spiral trajectory by means of the spiral propulsion, thereby realizing the directional conveying and centralized cleaning of waste, and avoiding the accumulation of waste in the pit and affecting subsequent repair work. At the same time, combined with the negative pressure adsorption of the waste collection component 3, the grinding waste can be efficiently conveyed upward and collected, avoiding the waste residue from affecting the repair quality, and reducing pollution at the construction site.

[0016] More specifically, the suction hood 304 is connected to the rotating shaft 204 via a rotating bushing. The rotating bushing connects the suction hood 304 to the rotating shaft 204 but does not rotate with the rotating shaft 204, ensuring that the suction hood 304 remains fixed when the grinding head 205 rotates, thus stably collecting waste. The conveying pipe 303 is made of corrugated pipe, which is extensible and adapts to the up and down movement of the lifting pallet 103, preventing the conveying pipe 303 from being pulled and damaged due to position changes. The collection box 301 is detachably connected to the lifting pallet 103, making it easy to disassemble the collection box 301 and clean the waste stored inside, thus improving operational convenience.

[0017] It is worth noting that a slide block is fixedly connected to the side of the lifting pallet 103 near the slide frame 102. The surface of the slide frame 102 is provided with a slide groove that mates with the slide block. A pusher 105 is fixedly installed on the top of the slide frame 102. The slide block mates with the slide groove on the slide frame 102 to provide guidance for the up and down movement of the lifting pallet 103 and ensure the stability of the movement. The slide groove mates with the slide block to limit the movement trajectory of the lifting pallet 103 and ensure that it moves vertically along the slide frame 102. The pusher 105 makes it convenient for the operator to push the traveling trolley 101 to adjust the position of the equipment and improve the mobility of the equipment.

[0018] It is worth mentioning that the spiral direction of the spiral groove 2053 is adapted to the rotation direction of the grinding head 205 body. This ensures that when the grinding head 205 rotates, the spiral groove 2053 can effectively push the waste upward, realize the directional conveying of waste, and improve the waste collection efficiency.

[0019] Working Principle: This embodiment provides a road maintenance pothole treatment device. In use, the hand-operated frame 105 is pushed to move the device to the side of the pothole. The horizontal position of the grinding head 205 is adjusted by the longitudinal displacement mechanism 201 and the lateral displacement mechanism 202 to align it with the pothole. The cylinder 104 is activated, driving the lifting plate 103 to move downwards along the slide 102, allowing the grinding head 205 to extend into the pothole. The extension and retraction of the cylinder 104 is controlled according to the pothole depth. The motor 203 is then started to drive... The grinding head 205 rotates at high speed, and the inclined surface 2051 and the flat surface 2052 of the grinding head 205 grind the side wall of the pit, so that the edge of the pit forms a regular stepped cross section. During the rotation, the spiral groove 2053 conveys the waste generated by grinding upward along the groove to the collection trough 2054. The negative pressure pump 302 is started to form a negative pressure in the collection box 301, and the suction hood 304 sucks the waste in the collection trough 2054 into the collection box 301 for storage through the conveying pipe 303.

[0020] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
