Description

Technical Field

[0001] This utility model relates to the field of road repair technology, and in particular to a flexible asphalt road repair device. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials into mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. It is a widely used high-grade pavement in road construction. However, after long-term use, potholes will appear on the pavement, affecting road safety. Therefore, asphalt pavement repair devices are needed to repair the pavement.

[0003] A search revealed Chinese Patent Publication No. CN212477381U, which discloses an asphalt pavement repair device. The device includes a workbench with wheels, a material supply bucket mounted on the workbench, a force-applying handle fixedly installed at one end of the workbench, and a compaction roller located at the lower end of the workbench. Both ends of the compaction roller are rotatably connected to mounting rods. The mounting rods are vertically oriented and slide through the workbench. Mounting seats are fixedly installed on both sides of the workbench, and turntables are rotatably connected to the mounting seats. A first force transmission rod is fixedly connected horizontally to the upper end of the mounting rods, and a first compensation rod is formed along its length on the first force transmission rod. The device has a eccentrically mounted force transmission block on the turntable. The force transmission block is slidably connected to the compensation groove and rotatably connected to the compensation groove. When passing over a road surface that does not need repair, the turntable can be rotated to apply force to the first force transmission rod through the force transmission block, thereby causing the mounting rod to move upward and the compaction roller to leave the ground. At this time, the repair device can be smoothly pushed without affecting the unbroken ground. However, in actual use, since the outlet position remains unchanged when discharging asphalt, it is necessary to change the orientation of the worktable by pushing the action table so that the discharge port can face the pothole. The operation is cumbersome and reduces the practicality of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a flexible asphalt pavement repair device, which aims to improve the problem of the existing technology requiring constant adjustment of the action to align the discharge port with the pothole, resulting in a cumbersome operation process.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a flexible asphalt pavement repair device, comprising a mobile trolley, a fixed plate fixedly connected to the top of the mobile trolley, a storage cylinder fixedly connected to the top center of the fixed plate, a mixing assembly provided on the inner wall of the storage cylinder, a discharge pipe connected to the bottom right side of the storage cylinder, a control valve fixedly connected to the top of the outer wall of the discharge pipe, a spraying mechanism provided on the right side of the fixed plate, and a compaction mechanism provided on the left side of the outer wall of the mobile trolley; the spraying mechanism includes an infrared heating lamp, the outer left side of the infrared heating lamp fixedly connected to the right side of the outer wall of the fixed plate, a reserved groove opened on the top right side of the fixed plate, a conical hopper rotatably connected to the inner wall of the reserved groove, a conveying pipe connected to the bottom of the conical hopper, a uniform spray head connected to the bottom end of the conveying pipe, flow equalization plates fixedly connected to the front and rear sides of the inner wall of the uniform spray head, a rotating assembly provided on the outer wall of the conical hopper, and a leveling assembly provided at the bottom center of the mobile trolley.

[0006] Through the above technical solution: the mobile trolley carries all components to the location of the road surface to be repaired; the fixed plate provides installation support for other components; the mixing component in the storage cylinder mixes the material evenly to ensure the quality of the repair material; when discharge is required, the control valve is opened, and the material flows out from the discharge pipe into the conical hopper. Previously, the infrared heating lamp has heated the road surface to facilitate better material adhesion; the rotating component drives the conical hopper to rotate in the reserved groove, adjusting the discharge direction; the material flows through the conveying pipe to the uniform spray head; the uniform plate evenly sprinkles the material on the road surface; then, the leveling component flattens the sprinkled material; finally, as the mobile trolley continues to move to the appropriate position, the compaction mechanism compacts the flattened material, completing the road surface repair work.

[0007] As a further description of the above technical solution: The compaction mechanism includes two T-shaped blocks. The right sides of the outer walls of the two T-shaped blocks are fixedly connected to the front and rear sides of the outer wall of the mobile trolley, respectively. A compaction block is provided on the left side of the outer wall of the mobile trolley. T-shaped grooves are provided on the front and rear sides of the right side of the outer wall of the compaction block. The two compaction blocks are slidably connected to the corresponding T-shaped grooves. A motor is fixedly connected to the top left side of the fixed plate. A rotating disk is fixedly connected to the output end of the motor. A connecting rod is rotatably connected to the rear side of the left side of the outer wall of the rotating disk. The bottom end of the connecting rod is rotatably connected to the top of the compaction block.

[0008] Through the above technical solution: When the compaction mechanism is working, motor 1 is fixed to the top left side of the fixed plate. After starting, its output end drives the rotating disk to rotate. The connecting rod connected to the rear left side of the outer wall of the rotating disk will make a circular motion with the rotating disk because it is connected to the rotation of the rotating disk. At the same time, two T-blocks are fixed to the front and rear ends of the left side of the outer wall of the moving trolley, respectively. The compaction block is located on the left side of the outer wall of the moving trolley. The T-slots opened on the front and rear sides of its right end slide with the T-blocks. This fit restricts the movement direction of the compaction block, so that it can only move up and down. As the rotating disk rotates, the connecting rod converts the circular motion of the rotating disk into vertical motion, driving the compaction block to move up and down. Thus, the bottom of the compaction block continuously taps the asphalt material that has been flattened by the leveling component, making it more compact and improving the quality of the road surface repair.

[0009] As a further description of the above technical solution: The rotating assembly includes a toothed ring, the inner wall of which is fixedly connected to the top of the outer wall of the conical bucket. A toothed plate is slidably connected to the middle of the top of the fixed plate. A push rod is fixedly connected to the right side of the top of the fixed plate, and the rear end of the push rod is fixedly connected to the middle of the right side of the outer wall of the toothed plate.

[0010] The above technical solution works as follows: When it is necessary to adjust the direction of the conical bucket, the push rod is activated. The push rod is fixed on the top right side of the fixed plate. It drives the toothed plate connected to it to slide in the middle of the top of the fixed plate. The toothed plate and the toothed ring mesh with each other. The inner wall of the toothed ring is fixed to the top of the outer wall of the conical bucket. When the toothed plate slides, it drives the toothed ring to rotate through the meshing action, thereby driving the conical bucket to rotate in the reserved groove, thus realizing the adjustment of the discharge direction.

[0011] As a further description of the above technical solution: The leveling assembly includes two rotating sleeves. The tops of the two rotating sleeves are respectively fixedly connected to the front and rear sides of the bottom of the mobile trolley. The inner walls of the two rotating sleeves are rotatably connected to the same rotating plate. The bottom right side of the mobile trolley is fixedly connected to a rotating seat one. The inner wall of the rotating seat one is rotatably connected to a telescopic rod. The outer right side of the rotating plate is fixedly connected to a rotating seat two. The bottom of the outer wall of the telescopic rod is rotatably connected to the inner wall of the rotating seat two. The bottom of the rotating plate is fixedly connected to a rubber strip.

[0012] Through the above technical solution: when the leveling component is working, the telescopic rod extends and retracts. One end of the telescopic rod is rotatably connected to the rotating seat one, which is fixed on the right side of the bottom of the mobile trolley; the other end is rotatably connected to the rotating seat two, which is fixed on the right side of the outer wall of the rotating plate. The extension and retraction of the telescopic rod causes the rotating plate to rotate around the rotating sleeve. The rotating sleeve is fixed on the front and rear sides of the bottom of the mobile trolley. After the rotating plate is lowered, the bottom rubber strip contacts the road surface and moves with the mobile trolley to level the material.

[0013] As a further description of the above technical solution: The stirring assembly includes a rotating rod, the bottom end of which is rotatably connected to the bottom of the inner wall of the storage cylinder. Multiple stirring rods are fixedly connected to the upper and lower sides of the outer wall of the rotating rod. A second motor is fixedly connected to the top center of the moving trolley. The output end of the second motor passes through the fixed plate and is fixedly connected to the bottom end of the storage cylinder and the rotating rod.

[0014] Through the above technical solution: when the mixing component is working, motor 2 is fixed on the top side of the mobile trolley. When motor 2 is started, its output end rotates, and the power is transmitted to the bottom of the rotating rod through the fixed plate and the storage cylinder, which drives the rotating rod to rotate at the bottom of the inner wall of the storage cylinder. Multiple mixing rods fixed on the upper and lower sides of the outer wall of the rotating rod rotate accordingly, stirring the material in the storage cylinder, so that the material is evenly mixed and meets the requirements for road repair materials.

[0015] As a further description of the above technical solution: The top of the storage cylinder is rotatably connected to a protective cover. Two hooks are fixedly connected to the right side of the outer wall of the protective cover. Two fasteners are fixedly connected to the top right side of the outer wall of the storage cylinder. The two fasteners are respectively engaged with the corresponding hooks.

[0016] The above technical solution allows the protective cover on the top of the storage cylinder to be rotated and fixed by hooks and latches, opening or closing the protective cover to protect the material inside the storage cylinder.

[0017] As a further description of the above technical solution: A protective cover is provided on the outside of the storage cylinder. The bottom of the protective cover is fixedly connected to the top of the fixing plate. An observation port is provided on the front side of the outer wall of the protective cover.

[0018] The above technical solution involves fixing the bottom of the protective cover to the top of the fixed plate, covering the storage cylinder for protection, and providing an observation port on its front side for easy viewing of the condition inside the storage cylinder.

[0019] As a further description of the above technical solution: A limiting ring is fixedly connected to the middle of the outer wall of the conical bucket, and a limiting groove is opened in the middle of the inner wall of the reserved groove. The limiting ring is rotatably connected to the limiting groove.

[0020] The above technical solution involves a rotatable connection between the outer wall limiting ring of the conical bucket and the inner wall limiting groove of the reserved slot, which restricts the axial movement of the conical bucket while allowing it to rotate flexibly.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the road pit is heated by an infrared heating lamp, the material flow is controlled by a control valve, and the push rod drives the toothed plate and toothed ring to rotate the conical bucket. This allows the material conveying pipe and the uniform spraying head to be precisely aligned with the pits at different locations, eliminating the need for frequent adjustments to the trolley's orientation. At the same time, the telescopic rod drives the rotating plate to spread the asphalt, and the rubber strip protects the rotating plate. This effectively improves the problem of cumbersome operation of aligning the discharge port with the road pit in the prior art, simplifies the road repair process, and improves repair efficiency.

[0022] 2. In this utility model, a motor drives a rotating disk to rotate. The rotating disk is connected to the compaction block via a connecting rod. At the same time, the sliding fit between the T-shaped block and the T-shaped groove on the compaction block restricts the compaction block to only move up and down. When the rotating disk rotates, the circular motion is converted into the up and down motion of the compaction block, realizing continuous pounding on the flattened asphalt material, making the asphalt material tightly bonded, filling the gaps, significantly improving the smoothness and firmness of the repaired road surface, and improving the quality of road repair.

The right sides of the outer walls of the two T-blocks 301 are fixedly connected to the front and rear sides of the outer wall of the moving trolley 1, respectively. The left side of the outer wall of the moving trolley 1 is provided with a compaction block 302, which serves as a component for directly compacting the leveled asphalt pavement. It can effectively transmit force to the pavement, making the asphalt more compact. The front and rear sides of the right side of the outer wall of the compaction block 302 are provided with T-slots 303 for sliding engagement with the T-blocks 301, thereby restricting the compaction block 302 to move only along the direction determined by the T-blocks 301.

A motor 503 is fixedly connected to the top center of the moving trolley 1 as the power source of the stirring assembly 5, providing the necessary driving force for the entire stirring action. The output end of the motor 503 passes through the fixed plate 4 and is fixedly connected to the bottom end of the rotating rod 501 in the storage cylinder 8. Specifically, when the stirring assembly 5 is working, the motor 503 is fixed on the top side of the moving trolley 1. After starting, its output end rotates. Since the output end passes through the fixed plate 4 and the storage cylinder 8 and is fixed to the bottom of the rotating rod 501, it drives the rotating rod 501 to rotate at the bottom of the inner wall of the storage cylinder 8. The multiple stirring rods 502 fixed on the upper and lower sides of the outer wall of the rotating rod 501 rotate accordingly to stir the material in the storage cylinder 8 and ensure that the material is uniform.

The outer side of the storage cylinder 8 is also equipped with… A protective cover 12 surrounds the outside of the storage cylinder 8, protecting it from damage caused by external impacts. The bottom of the protective cover 12 is fixedly connected to the top of the fixing plate 4. An observation port 13 is provided on the front side of the outer wall of the protective cover 12. A limiting ring 14 is fixedly connected to the middle of the outer wall of the conical hopper 203, providing a limiting structure for the rotation of the conical hopper 203 and ensuring that it rotates within a specific range. A limiting groove 15 is provided in the middle of the inner wall of the reserved groove 202, which is used to cooperate with the limiting ring 14 to further limit the rotation range of the conical hopper 203 and ensure the stability of the rotation of the conical hopper 203. The limiting ring 14 and the limiting groove 15 are rotatably connected. Specifically, the protective cover 9 at the top of the storage cylinder 8 is engaged with the latch 11 via the hook 10, which can prevent foreign objects from entering the storage cylinder 8 and protect the material inside the cylinder. The protective cover 12 is fixed to the top of the fixing plate 4 and surrounds the storage cylinder 8. Its observation port 13 makes it easy to check the material condition. The limiting ring 14 of the conical hopper 203 is rotatably connected to the limiting groove 15 of the reserved groove 202, which ensures the rotational flexibility of the conical hopper 203 while restricting its up and down movement to ensure stable material discharge.

[0030] Working principle: When the mobile trolley 1 encounters a pothole while traveling on the road, the infrared heating lamp 201 is activated first. The infrared heating lamp 201 is fixed to the right side of the fixing plate 4 to heat the surface of the pothole and soften the road surface, preparing it for subsequent asphalt filling. As the trolley continues to move forward, the control valve 7 is opened. The control valve 7 is located at the top of the discharge pipe 6, controlling the outflow of material from the storage cylinder 8. The material flows from the storage cylinder 8 through the discharge pipe 6 into the conical hopper 203. The conical hopper 203 is located in the reserved groove 202 and is rotatable. The material then flows from the conveying pipe 204 at the bottom of the conical hopper 203 into the equalizing head 205. The equalizing plate 206 inside the equalizing head 205 evenly distributes the material, ensuring it is evenly sprinkled onto the road surface requiring repair. During this process, to adapt to potholes in different locations and avoid frequent adjustments to the orientation of the moving trolley 1, the push rod 2073 is activated. The push rod 2073 is fixed to the top right side of the fixed plate 4, causing the toothed plate 2072 to slide back and forth. The toothed plate 2072 engages with the toothed ring 2071. 2071 is fixed to the top of the outer wall of the conical hopper 203, thereby driving the conical hopper 203 to rotate within the reserved groove 202, which in turn causes the conveying pipe 204 and the uniform spray head 205 to swing back and forth, precisely aligning with the pits at different positions. As the trolley continues to move forward, the telescopic rod 2084 is activated. One end of the telescopic rod 2084 is connected to the rotating seat 1 2083, which is fixed to the bottom right side of the moving trolley 1; the other end is connected to the rotating seat 2085, which is fixed to the rotating plate 2. When the telescopic rod 2084 extends from the right side of the outer wall of 082, it drives the rotating plate 2082 to rotate along the connection point with the rotating sleeve 2081, so that the rotating plate 2082 is lowered into a vertical state. The moving trolley 1 continues to move, and the rotating plate 2082 flattens the asphalt on the road surface. The rubber strip 2086 at the bottom of the rotating plate 2082 plays a role in protecting the rotating plate 2082 and preventing damage to the rotating plate 2082 from road protrusions. The whole process is efficient and flexible, greatly simplifying the road repair operation. As the mobile trolley 1 continues to move, motor 304, mounted on the top left side of the fixed plate 4, starts. Motor 304 acts as a power source, its output driving the rotating disk 305 to rotate. A connecting rod 306 is rotatably connected to the rear left side of the outer wall of the rotating disk 305, and the bottom end of the connecting rod 306 is rotatably connected to the top of the compaction block 302. Simultaneously, two T-shaped blocks 301 are fixed to the front and rear ends of the left side of the mobile trolley 1, respectively. T-slots 303 on the front and rear right sides of the outer wall of the compaction block 302 slide in cooperation with the T-shaped blocks 301. This structural design plays a crucial guiding role, restricting the movement direction of the compaction block 302, allowing it to only move in one direction. As the rotating disk 305 rotates, due to its rotational connection with the connecting rod 306 and the compaction block 302, the circular motion of the rotating disk 305 is converted into the up-and-down motion of the compaction block 302 through the connecting rod 306. During the continuous rotation of the rotating disk 305, the compaction block 302 will continuously move up and down. At this time, the bottom of the compaction block 302 will continuously tap the asphalt material flattened by the rotating plate 2082. Through this regular tapping action, the asphalt material can be more tightly bonded, filling any gaps that may exist, thereby making the material more compacted and improving the smoothness and strength of the repaired road surface.
