Description

Technical Field

[0001] The utility model relates to the technical field of road surface repair equipment, in particular to an asphalt road crack repair device. Background Art

[0002] Asphalt pavement cracking during its service life is a common problem in countries around the world. The harm of pavement cracks lies in the continuous entry of moisture through the cracks, which softens the base layer and even the roadbed, resulting in a decrease in the bearing capacity of the pavement, and causing problems such as pumping, steps, and cracks, thereby accelerating pavement damage. The main causes of asphalt pavement cracking can be divided into two categories. One is structural damage cracks caused by the action of vehicle loads, generally referred to as load-type cracks, and the other is mainly cracks caused by temperature changes in the asphalt surface layer, including low-temperature shrinkage cracks and fatigue cracks, generally referred to as non-load-type cracks; when such cracks appear on the asphalt pavement, the pavement needs to be repaired to avoid continued damage to the road.

[0003] For example, the patent number CN219137347U is a road crack repair device, which includes a cart and a storage box, the storage box is fixedly installed on the upper surface of the cart, the upper surface of the storage box is fixedly equipped with a feed pipe, the lower surface of the cart is fixedly equipped with a discharge pipe, the lower surface of the cart is equipped with a sleeve, the inner wall of the sleeve is slidably connected with a sleeve rod, the bottom end of the sleeve rod is equipped with a mounting block, and the outer surface of the sleeve is sleeved with a spring. By setting the cart, storage box, feed pipe and discharge pipe, asphalt and other repair agents are added to the interior of the storage box through the feed pipe, and the cart is pushed to move on the road. When the cart moves, the asphalt and other repair agents in the storage box flow downward to cover the cracks. In the process of the cart moving, the pressure roller rolls closely against the road surface to flatten the asphalt and other repair agents to prevent the road surface from having poor flatness after repair, thereby achieving the road crack repair work.

[0004] However, the road crack repair device in the above technology still has the following problems:

[0005] Since the repair agent flows downward from the top and fills the cracks in the road, the repair agent may not be able to fill to the bottom of the cracks, resulting in incomplete crack filling and repair, which leads to poor water sealing effect of the cracks, weak adhesion of the cracks, and easy re-occurrence of cracks.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 - Figure 4 A device for repairing cracks in an asphalt road comprises a cart 1 and a storage box 2 mounted on the cart 1, a flattening roller 3 is mounted on the bottom of the cart 1 at one end away from the storage box 2, an observation port 101 is penetrated through the upper surface of the cart 1 near the end of the flattening roller 3, a pressure pump 4 is fixedly connected to the upper surface of the cart 1 on one side of the observation port 101, an extraction end of the pressure pump 4 is connected to an extraction pipe 5, the other end of the extraction pipe 5 penetrates the storage box 2 and is connected to the storage box 2, an output end of the pressure pump 4 is connected to an output pipe 6, a limiting ring 7 is fixedly connected to the inner wall of the observation port 101 near the storage box 2, and the other end of the output pipe 6 passes through the limiting ring 7 and is slidably connected to the limiting ring 7.

[0023] like Figure 1 - Figure 4 As shown, the asphalt road crack repair device in the utility model is similar in structure to the existing asphalt road crack repair device, such as a road crack repair device disclosed in the patent with publication number CN219137347U. The main improvement of the utility model is that the repair liquid can be poured into the deepest part of the road crack as much as possible, thereby improving the repair effect of the road crack. Figures 1 to 4As shown, when the asphalt road crack repair device of the utility model is in use, the output pipe 6 is passed through the limit ring 7, and the output port of the output pipe 6 is in contact with the surface of the road crack, and then the pressure pump 4 is started, and the pressure pump 4 extracts the road repair liquid in the storage box 2 through the extraction pipe 5, and then the extracted repair liquid is poured into the road crack through the output pipe 6, and at the same time, the pressure pump 4 provides high pressure to the repair liquid, so that the speed of the repair liquid rushing out of the output pipe 6 is increased, so that the repair liquid impacts the road crack below from the output pipe 6, so that the repair liquid is poured into the depth of the road crack as much as possible, and the repair effect of the road crack is improved. As the cart 1 continues to move forward, the flattening roller 3 can compact and smooth the repair liquid overflowing from the road crack, so that the repair appearance is smoother and more beautiful.

[0024] like Figure 1 - Figure 4 As shown, the extraction pipe 5 is L-shaped, one end of the extraction pipe 5 is sleeved with the extraction end of the pressure pump 4 and is fixedly connected thereto, and the end of the extraction pipe 5 away from the pressure pump 4 passes through the storage box 2 and is located at the center of the bottom surface of the storage box 2. The extraction pipe 5 is arranged in an L shape, and the extraction port of the extraction pipe 5 is arranged at the center of the bottom surface of the storage box 2, so that the extraction pipe 5 can be extracted from the bottom center of the storage box 2, thereby preventing a little repair liquid from remaining in the storage box 2 and being unable to be extracted.

[0025] like Figure 1 - Figure 4 As shown, the output end of the booster pump 4 is connected with a hose 8, and the other end of the hose 8 is connected with the output pipe 6. The output end of the booster pump 4 is connected with the output pipe 6 through the hose 8, so that after the output pipe 6 is inserted into the limit ring 7, it can be moved up and down slightly, so that the bottom of the output pipe 6 can be attached to the road crack.

[0026] like Figure 1 - Figure 4 As shown, both ends of the hose 8 are fixedly connected and communicated with an internal threaded member 9, and the two internal threaded members 9 are respectively threadedly connected with the output end of the booster pump 4 and the output pipe 6. The internal threaded member 9 is connected with the output pipe 6 and the booster pump 4, so that the hose 8 can be replaced easily after being broken during long-term use.

[0027] like Figure 1 - Figure 4As shown, the outer wall of the output pipe 6 near one end of the hose 8 is fixedly connected with a positioning ring 10, and the side of the positioning ring 10 near the storage box 2 is connected with a telescopic assembly, and the other side of the telescopic assembly is connected to the cart 1. When the bottom of the output pipe 6 comes into contact with the road crack, since the crack is mostly not flat, the output pipe 6 will vibrate slightly up and down. At this time, the output pipe 6 can always fit the bottom crack through the positioning ring 10 and the telescopic assembly, thereby improving the crack repair effect.

[0028] like Figure 2 and Figure 4 As shown, the telescopic assembly includes a connecting plate 11 and a telescopic spring 12. The connecting plate 11 is fixedly connected to the side of the positioning ring 10 close to the storage box 2. The telescopic spring 12 is located between the cart 1 and the connecting plate 11, and the two ends of the telescopic spring 12 are respectively fixedly connected to the cart 1 and the connecting plate 11. The telescopic spring 12 always pulls the connecting plate 11 downward, thereby cooperating with the positioning ring 10 to pull the output pipe 6 downward, so that the bottom output port of the output pipe 6 always rests on the road crack, improving the stability when the repair liquid is poured into the crack.

[0029] like Figure 3 and Figure 4 As shown, a limit rod 13 is fixedly connected to the upper surface of the cart 1, and the other end of the limit rod 13 penetrates the telescopic spring 12 and the connecting plate 11, and is slidably connected to the connecting plate 11. When the telescopic spring 12 pulls the output tube 6 downward, the limit rod 13 penetrates the connecting plate 11, so that when the output tube 6 moves up and down, the telescopic spring 12 always maintains a vertical state, avoiding deformation and distortion, and improving the stability of the telescopic structure.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
