Abstract
Description
Technical Field
[0001] This utility model relates to the field of road maintenance equipment technology, and in particular to a road crack repair device. Background Technology
[0002] With the continuous increase in traffic flow and the increasing vehicle load, roads inevitably develop cracks and other defects during long-term use. If road cracks are not treated in time, rainwater will seep into the road base, causing damage to the road structure, further aggravating road damage, and increasing road maintenance costs.
[0003] Existing crack filling and repair devices all require manual repair, and the filling location cannot be accurately positioned during the repair process, resulting in a large amount of asphalt waste. The flow rate of asphalt cannot be adjusted, and because the cracks on the road are of inconsistent sizes, while the nozzle size of the repair device is fixed, it is difficult to adjust the nozzle position when the crack location and depth are inconsistent.
[0004] The existing patent (publication number: CN221094789U) relates to the field of highway maintenance technology, and in particular to an asphalt road crack filling device. It includes a mobile trolley with an asphalt storage tank connected to its end face. A controller is connected to the side wall of the asphalt storage tank. An adjustable filling and grouting structure is connected to the end face of the mobile trolley and to the outlet of the asphalt storage tank. This invention, by setting an adjustable filling and grouting structure in the asphalt road crack filling device, utilizes a drive motor and an electric telescopic rod within the adjustable filling and grouting structure, and through a transmission structure, to adjust the position of one end of the auger connecting cavity relative to the ground. This design allows for multi-directional adjustment, making the outlet of the device more accurate in relation to the road crack, and thus making the filling more efficient. It solves the problem of inconvenient multi-directional adjustment, which leads to inaccurate positioning of the outlet of the device relative to the road crack.
[0005] To address the aforementioned problems, existing patents have provided solutions. However, the current method of crack filling typically involves spraying filling material onto the crack in the road using a spray gun. However, the sprayed filling material is difficult to penetrate into the crack and tends to accumulate around the crack opening and spread outwards, making it difficult to achieve a good crack filling and repair effect. At the same time, this inadequate filling method also reduces the utilization rate of the filling material, resulting in material waste.
[0006] Therefore, a road crack repair device is proposed. Utility Model Content

[0028] A road crack repair device includes a trolley 1, a repair component 2 is provided on the front side of the trolley 1, and a material supply component 3 for use with the repair component 2 is provided on the top of the trolley 1.
[0029] The seam repair assembly 2 includes two L-shaped frames 201, which are fixedly connected to the two sides of the front top of the trolley 1. A lifting air rod 202 is fixedly connected to the front bottom of the L-shaped frame 201. A fixed frame 203 is fixedly connected to the output end of the two lifting air rods 202.

The output rod of the compression cylinder 205 passes through the fixed frame 203 and is fixedly connected to a compression plate 206 that matches the internal size of the positioning filling frame 204.
[0030] In this embodiment: by setting up a trolley 1, a crack filling component 2, and a filler material supply component 3, the trolley 1 facilitates mobile crack filling work during use. The crack filling component 2 allows for precise positioning of the filler material when filling road cracks, concentrating the filler material at the crack location and preventing it from spreading to the surrounding area. It also applies pressure to the filler material, squeezing it into the interior of the crack, thereby effectively improving the crack filling and repair effect. Furthermore, by preventing the filler material from spreading to the surrounding area, the utilization rate of the filler material is improved, avoiding waste. The filler material supply component 3 allows for the storage of the filler material and the supply and delivery of the filler material into the crack filling component 2. It also allows for the stirring and heating of the stored filler material, thereby preventing the filler material from settling and solidifying.
[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the material supply component 3 includes a storage tank 301. The bottom of the front side of the storage tank 301 is connected to a material pump 302 via a pipe. The bottom of the material pump 302 is fixedly connected to the front side of the top of the trolley 1. The outlet of the material pump 302 is connected to a corrugated material conveying pipe 303. The other end of the corrugated material conveying pipe 303 is connected to the top of the rear side of the positioning filling frame 204.
[0032] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, multiple heating tubes 304 are fixedly connected to the four sides of the inner wall of the storage box 301.

The bottom of the stirring shaft 306 extends to the bottom of the inner cavity of the storage box 301. The top of the surface of the stirring shaft 306 is rotatably connected to the inner wall of the storage box 301 through a bearing. Multiple stirring blades 307 are fixedly connected to the surface of the stirring shaft 306.
[0033] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, a feeding pipe 308 is connected to the front side of the top of the storage box 301, and a sealing cap 309 is connected to the top of the surface of the feeding pipe 308 by a thread.
[0034] In this embodiment: by setting up a storage tank 301, a feed pump 302, a corrugated feed pipe 303, a heating pipe 304, a stirring motor 305, a stirring shaft 306, stirring blades 307, a feeding pipe 308, and a sealing cover 309, in use, the filler material is added into the storage tank 301 through the feeding pipe 308 and then the sealing cover 309 is closed. The storage tank 301 can store the filler material, and then the heating pipe 304 can heat the filler material inside the storage tank 301 to prevent the filler material from solidifying. Furthermore, the system can be activated by starting... The stirring motor 305 is activated, causing the output shaft of the stirring motor 305 to drive the stirring shaft 306 to rotate. The stirring shaft 306 will drive the stirring blade 307 to rotate. The rotation of the stirring blade 307 can stir the filling material and prevent the filling material from settling. Then, the feed pump 302 can be started to extract the filling material in the storage tank 301 through the pipeline and transfer it to the positioning filling frame 204 through the corrugated feed pipe 303, thereby achieving the effect of supplying and conveying the filling material in the positioning filling frame 204.
[0035] Specifically, such as Figure 1 , Figure 3 As shown, elastic pads 4 are fixedly connected around the bottom of the positioning filling frame 204. The elastic pads 4 are made of rubber.
[0036] Specifically, such as Figure 3 As shown, the top of the fixed frame 203 is provided with a through hole 5 for use with the extrusion cylinder 205, and the output rod of the extrusion cylinder 205 is slidably connected to the inner wall of the through hole 5.
[0037] In this embodiment: by setting the elastic pad 4, the positioning filling frame 204 can better fit with the ground, thereby improving the positioning effect of the positioning filling frame 204 on the filling material. By setting the through hole 5, the output rod of the extrusion cylinder 205 can pass through the fixed frame 203 for telescopic output.
[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, limit rods 6 are fixedly connected to both sides of the top of the extrusion plate 206, and the top of the limit rods 6 extends through to the top of the fixing frame 203.
[0039] Specifically, such as Figure 3 As shown, sliding holes 7 are provided on both sides of the top of the fixing frame 203 to cooperate with the limiting rod 6, and the surface of the limiting rod 6 is slidably connected to the inner wall of the sliding hole 7.
[0040] In this embodiment: by setting the limiting rod 6, the extrusion plate 206 can be guided and limited, so that the extrusion plate 206 can move up and down stably. By setting the sliding hole 7, the limiting rod 6 can follow the extrusion plate 206 up and down.
[0041] Working Principle: During use, the filler material is added to the storage tank 301 through the feeding pipe 308 and the sealing cover 309 is closed. The storage tank 301 stores the filler material. The heating pipe 304 heats the filler material inside the storage tank 301 to prevent condensation. The stirring motor 305 is activated, causing its output shaft to drive the stirring shaft 306, which in turn drives the stirring blades 307. The stirring blades 307 agitate the filler material, preventing sedimentation. The device is then moved to the area of the road requiring filling via the trolley 1, with the positioning filling frame 204 positioned above the road crack. The lifting air spring 202 is then activated, causing its output rod to move the fixing frame 203 and the positioning filling frame 204 downwards, allowing the positioning filling frame 204 to... After the elastic pad 4 is tightly attached to the ground, the material pump 302 can be started to extract the filling material from the storage tank 301 through the pipeline and transfer it to the positioning filling frame 204 through the corrugated material conveying pipe 303. The positioning filling frame 204 can position the filling material, so that the filling material is concentrated at the crack and cannot spread to the surrounding area. After a suitable amount of filling material is delivered into the positioning filling frame 204, the extrusion cylinder 205 can be started. The output rod of the extrusion cylinder 205 drives the extrusion plate 206 to move downward into the positioning filling frame 204 and apply pressure to the filling material. This can squeeze the filling material into the inside of the crack, thereby effectively improving the crack filling and repair effect. Moreover, the positioning filling frame 204 restricts the filling material, preventing it from spreading to the surrounding area, improving the utilization rate of the filling material and avoiding waste.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
