Description

Technical Field

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

[0002] In the repair and construction of municipal asphalt pavement, the main material usually used is asphalt. Other substances are added and mixed together to fill the cracks in the municipal asphalt pavement. After filling the cracks, the filler usually needs to be spread out. After the asphalt filler is spread out, it is usually required that the filler be higher than the ground by a certain thickness, generally 1 cm higher than the ground.

[0003] For example, the authorized announcement number "CN214939141U" describes a repair auxiliary device for municipal asphalt pavement repair. Although the device allows the scraper of the paving component to slide horizontally over the road surface by sliding along the groove, and then repeatedly moving the scraper to spread the sealant at the crack, replacing the manual spreading method by maintenance personnel using the back of a shovel, thus improving the efficiency of spreading the sealant, this device requires adjusting the adjustable pads first, and then measuring or visually adjusting the bottom of the scraper to be about 1 cm from the ground. This operation is cumbersome and complex, increasing the workload. At the same time, the length of the crack can sometimes be very long, and due to the limitations of the groove and guide hole, the device needs to be installed and adjusted multiple times, which greatly causes inconvenience and reduces work efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a repair auxiliary device for asphalt pavement repair.

Two first wheel frames are provided at the lower ends of the two front support legs, and first rollers are rotatably connected between adjacent first wheel frames. Rotating rolling components are provided at the lower ends of the two rear support legs. A second support plate is provided below the first support plate. Multiple scrapers are provided on the lower surface of the second support plate. Multiple mounting blocks are evenly distributed around the upper surface of the second support plate. Multiple clamping components are provided between the mounting blocks and the first support plate. Sliding devices are provided on the side surfaces of the mounting blocks on both the left and right sides. A pusher is provided on the rear side of the upper surface of the first support plate.

[0007] Preferably, the rotating and rolling assembly includes a second wheel frame, with a second roller rotatably connected between the inner walls on both sides of the second wheel frame. A first connecting shaft is provided on the upper surface of the second wheel frame. A rotating cavity is provided inside the lower part of the support leg. A rotating block is provided inside the rotating cavity. The upper end of the first connecting shaft passes through the lower end of the support leg and is connected to the lower surface of the rotating block.

[0008] Preferably, the clamping assembly includes a slide rod, the upper end of which is connected to the lower surface of the first support plate, the lower end of which slides through the mounting block and is provided with a limiting end block, and a spring is sleeved on the outside of the slide rod, the upper end of which is connected to the lower surface of the first support plate, and the lower end of which is connected to the upper surface of the mounting block.

[0009] Preferably, the sliding device includes a fixed block, which is disposed on the side surface of the mounting block. The fixed block is rotatably connected to a second connecting shaft. A third wheel frame is provided at the lower end of the second connecting shaft. A third roller is rotatably connected between the inner walls on both sides of the third wheel frame. The surface of the third roller is uniformly provided with anti-slip grooves in an annular shape.

[0010] Preferably, the lower surface of the mounting blocks on both the left and right sides is provided with a strip hole, and the opposing side surface of the two fixing blocks is provided with a fixing rod. The opposing ends of the two fixing rods pass through the strip hole and are threaded with nuts.

[0011] Preferably, the surface of the first support plate is provided with a first observation through hole, and the surface of the second support plate is provided with a plurality of second observation through holes, all of which are disposed between two adjacent scrapers.

[0012] The present invention proposes an auxiliary repair device for asphalt pavement repair, which has the following advantages: The sliding device sets the height difference between the bottom end of the sliding device and the bottom end of the scraper to about 1 cm in one go, eliminating the need to measure or visually estimate the distance between the bottom end of the scraper and the ground each time. This simplifies operation and reduces workload. The device can be moved by the first roller and the rotating rolling assembly, allowing the scraper to sweep horizontally over the road surface and spread the accumulated crack filler. Repeating this process multiple times can flatten the crack filler, eliminating the need for repeated installation and adjustment of the device, greatly improving convenience and work efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-3 An auxiliary device for asphalt pavement repair includes a first support plate 1. Support legs 2 are provided at the four corners of the lower surface of the first support plate 1. Two first wheel frames 3 are provided at the lower ends of the two front support legs 2. First rollers 4 are rotatably connected between the two adjacent first wheel frames 3. Rotating rolling components are provided at the lower ends of the two rear support legs 2. A second support plate 5 is provided below the first support plate 1. Multiple scrapers 6 are provided on the lower surface of the second support plate 5. Multiple mounting blocks 7 are evenly provided around the upper surface of the second support plate 5. Multiple clamping components are provided between the mounting blocks 7 and the first support plate 1. Sliding devices are provided on the side surfaces of the mounting blocks 7 on the left and right sides. A pusher 8 is provided on the rear side of the upper surface of the first support plate 1.

[0019] The rotating and rolling assembly includes a second wheel frame 9, with second rollers 10 rotatably connected between the inner walls of both sides of the second wheel frame 9. A first connecting shaft 11 is provided on the upper surface of the second wheel frame 9. A rotating cavity 12 is provided inside the lower part of the support leg 2, and a rotating block 13 is provided inside the rotating cavity 12. The upper end of the first connecting shaft 11 passes through the lower end of the support leg 2 and connects to the lower surface of the rotating block 13. The rotating and rolling assembly can be adjusted by controlling the pusher 8 to make the rotating block 13 rotate within the rotating cavity 12, thereby driving the first connecting shaft 11 and the second wheel frame 9 to rotate, and further driving the second rollers 10 to rotate. This allows the device to be adjusted to accommodate the irregular direction of the cracks.

[0020] The clamping assembly includes a slide rod 14, the upper end of which is connected to the lower surface of the first support plate 1, the lower end of which slides through the mounting block 7 and is provided with a limiting end block 15, and a spring 16 is sleeved on the outside of the slide rod 14, the upper end of which is connected to the lower surface of the first support plate 1, and the lower end of which is connected to the upper surface of the mounting block 7.

[0021] The sliding device includes a fixed block 17, which is disposed on the side surface of the mounting block 7. A second connecting shaft 18 is rotatably connected to the fixed block 17. A third wheel frame 19 is provided at the lower end of the second connecting shaft 18. A third roller 20 is rotatably connected between the inner walls of both sides of the third wheel frame 19. Anti-slip grooves 21 are evenly distributed in a ring on the surface of the third roller 20. This sliding device ensures that the height difference between the bottom of the sliding device and the bottom of the scraper 6 is approximately 1 cm in a single operation, eliminating the need to measure or visually estimate the distance between the bottom of the scraper 6 and the ground each time. This simplifies operation and reduces workload.

[0022] The lower surfaces of the mounting blocks 7 on both the left and right sides are provided with strip holes 22, and the opposing surfaces of the two fixing blocks 17 are provided with fixing rods 23. The opposing ends of the two fixing rods 23 pass through the strip holes 22 and are threaded with nuts 24.

[0023] The surface of the first support plate 1 is provided with a first observation through hole 25, and the surface of the second support plate 5 is provided with multiple second observation through holes 26, all of which are located between two adjacent scraper plates 6. The location of road surface cracks can be observed through the first observation through hole 25 and the second observation through hole 26.

[0024] Working principle: First, the fixed support rod 23 is adjusted up and down along the strip hole 22 until the height difference between the bottom end of the sliding device and the bottom end of the scraper 6 is about 1cm. The nut 24 is then threadedly connected to the fixed support rod 23. Under the compression force of the spring 16, the mounting block 7 moves downward, which in turn drives the second support plate 5, scraper 6 and sliding device to move downward, so that the third roller 20 contacts the ground. During the repair operation, sufficient filler is first filled into the road crack. The filler should be at least 1.5cm higher than the road surface. Then, the scraper 6 is used to sweep horizontally over the road surface and spread the accumulated crack filler. This process is repeated multiple times to flatten the crack filler.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
