Description

Technical Field

[0001] This application relates to the field of road construction, and more specifically, to a dynamic crack injection and repair device for asphalt pavement. Background Technology

[0002] After prolonged use, asphalt pavements are prone to cracking due to repeated vehicle traffic and temperature changes causing material shrinkage or expansion. When repairing these cracks, a crack grouting repair device is typically used. First, ground-penetrating radar is used to scan the pavement to generate a crack distribution map and determine the grouting hole locations. Second, vertical holes are drilled to the bottom of the base layer, and then pre-embedded guide pipes are inserted. Finally, grouting is initiated, and the grout penetrates the cracks under pressure, filling the voids and solidifying.

[0003] However, the existing dynamic crack grouting repair device for asphalt pavement still has the following shortcomings in use: When repairing cracks in existing asphalt pavement, multiple grouting holes need to be opened, and the distance between the grouting holes is mostly 10-20 cm. However, most existing crack grouting repair devices only have one output end, which cannot grout multiple grouting holes at the same time. The grouting holes need to be grouted one by one, which reduces the working efficiency of the crack grouting repair device. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a dynamic crack grouting repair device for asphalt pavement, which aims to improve the problem that most existing crack grouting repair devices only have one output end and cannot grout multiple grouting holes at the same time. They require grouting each grouting hole one by one, which reduces the working efficiency of the crack grouting repair device.

[0005] This application provides a dynamic crack grouting repair device for asphalt pavement, including a grouting device, an output mechanism for discharging grout at the output end of the grouting device, and an adjustment mechanism on one side of the grouting device;

[0006] The output mechanism includes a first pipe, one end of which is connected to the output end of the grouting device, and the other end of which is connected to a material conveying component. One side of the material conveying component is connected to multiple sets of second pipes, and one end of the first pipe is connected to an output head. The first pipe and the grouting device are detachably connected. When only one grouting hole needs to be grouted, the output mechanism can be replaced with a single output head. The length of the second pipe is sufficient for the output head to move left, right, up, and down.

[0007] In one specific implementation, vertical plates are connected to both sides of the feeding component, and a first horizontal plate and a second horizontal plate are connected between the two sets of vertical plates. A first slider is slidably connected to the outer surface of the first horizontal plate, and a second slider is slidably connected to the outer surface of the second horizontal plate.

[0008] In the above implementation process, by setting the first horizontal plate and the second horizontal plate, the first slider can slide on the outer surface of the first horizontal plate, and the second slider can slide on the outer surface of the second horizontal plate, limiting the sliding direction of the first slider and the second slider, so that the first slider and the second slider can only move horizontally.

[0009] In one specific implementation, a housing is connected to one side of one set of vertical plates, a motor is connected to the top of the housing, the output shaft of the motor passes through the housing and is connected to a screw, and the other end of the screw is rotatably connected inside the housing.

[0010] In the above implementation process, by setting up the motor, the output shaft of the motor can be controlled to rotate, which in turn drives the screw to rotate inside the housing.

[0011] In one specific implementation, the outer surface of the screw is threadedly connected to a threaded seat, which is slidably connected inside the housing.

[0012] In the above implementation process, by setting the screw, the threaded seat can be driven to move up and down inside the housing when the screw rotates.

[0013] In one specific implementation, a connecting plate is connected to one side of the threaded seat, and a track plate is connected to one end of the connecting plate.

[0014] In the above implementation process, by setting the threaded seat, the connecting plate can be driven to move up and down when the threaded seat moves up and down, and the track plate can be driven to move up and down.

[0015] In one specific implementation, multiple sets of sliding grooves are formed through one side of the track plate.

[0016] In the above implementation process, by setting the sliding groove, the first slider and the second slider can be driven to slide when the track plate moves up and down.

[0017] In one specific implementation, a U-shaped component is connected to one side of the first slider, the U-shaped component is connected to one side of the second slider, and a protrusion is connected inside the U-shaped component, the protrusion sliding inside the sliding groove.

[0018] In the above implementation process, by setting the protrusion, when the track plate moves up and down, the protrusion can be driven to slide inside the sliding groove, which can drive the U-shaped part to move left and right, drive the output head to move left and right, adjust the distance between multiple sets of output heads to adapt to different distances between grouting holes, and enable multiple sets of output heads to simultaneously grout multiple grouting holes, thereby improving the grouting efficiency of the grouting device.

[0019] In one specific implementation, the adjusting mechanism includes multiple sets of cylinders, each set of cylinders being connected to one side of the U-shaped component. The output end of each cylinder is connected to a movable component, which is sleeved on the outer surface of the second pipe.

[0020] In the above implementation process, by setting up the cylinder, the moving part can be driven to move up and down by controlling the cylinder, and the output head can be driven to move up and down. When cracks appear on the road surface, the insertion depth of different output heads can be adjusted.

[0021] In one specific implementation, the outer surface of the second pipe is provided with an external thread, and the inside of the output head is provided with an internal thread, wherein the external thread and the internal thread are threadedly connected.

[0022] In the above implementation process, by setting external and internal threads, it is possible to connect the external and internal threads, which facilitates the replacement of different models of output heads.

[0023] In one specific implementation, a through hole is provided at the bottom of the output head.

[0024] In the above implementation process, by setting through holes, different diameter through holes can be opened to make the output head belong to different models, and the output amount of the output head can be controlled. The output head with a larger through hole diameter is grouted by the grouting device and outputs more grout than the output head with a smaller diameter, which can adapt to the different grout amounts required inside different grouting holes.

[0025] Compared with the prior art, the beneficial effects of this application are as follows: By setting up the output mechanism and the adjustment mechanism, when the track plate is moved up and down by controlling the motor, the protrusion slides inside the sliding groove, the U-shaped part moves left and right, and the output head moves left and right. The distance between multiple sets of output heads can be adjusted to adapt to different distances between grouting holes. Multiple sets of output heads can be used to simultaneously grout multiple grouting holes, improving the grouting efficiency of the grouting device. Furthermore, by controlling the cylinder to move the moving part up and down, the output head can be moved up and down. When cracks appear in the road surface, the insertion depth of different output heads can be adjusted. By opening through holes of different diameters, the output heads can be of different models, and the output volume of the output heads can be controlled. The output head with a larger through hole diameter outputs more grout than the output head with a smaller diameter, which can adapt to the different grout volumes required inside different grouting holes. This solves the problem that most existing crack grouting repair devices only have one output end, which cannot grout multiple grouting holes at the same time and requires grouting each hole one by one, resulting in reduced working efficiency of the crack grouting repair device.

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] Please see Figure 1 This application provides a dynamic crack grouting repair device for asphalt pavement, including a grouting device 1.

[0038] Please see Figure 1 and Figure 2 The grouting device 1 is provided with an output mechanism 2 for outputting grout at its output end, and an adjustment mechanism 3 is provided on one side of the grouting device 1.

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The output mechanism 2 includes a first pipe 202. One end of the first pipe 202 is connected to the output end of the grouting device 1, and the other end of the first pipe 202 is connected to a material conveying component 201. One side of the material conveying component 201 is connected to multiple sets of second pipes 203. One end of the first pipe 202 is connected to an output head 204. The first pipe 202 and the grouting device 1 are detachably connected. When only one grouting hole needs to be grouted, the output mechanism 2 can be replaced with a single output head 204. The length of the second pipe 203 is sufficient for the output head 204 to move left, right, up and down.

[0040] In a specific configuration, vertical plates 206 are connected to both sides of the material conveyor 201. A first horizontal plate 207 and a second horizontal plate 208 are connected between the two sets of vertical plates 206. A first slider 2012 is slidably connected to the outer surface of the first horizontal plate 207, and a second slider 2013 is slidably connected to the outer surface of the second horizontal plate 208. The arrangement of the first horizontal plate 207 and the second horizontal plate 208 allows the first slider 2012 to slide on the outer surface of the first horizontal plate 207 and the second slider 2013 to slide on the outer surface of the second horizontal plate 208. This limits the sliding direction of the first slider 2012 and the second slider 2013, ensuring that the first slider 2012 and the second slider 2013 can only move horizontally.

[0041] In a specific configuration, one side of one set of vertical plates 206 is connected to a housing 209, and the top of the housing 209 is connected to a motor 2010. The output shaft of the motor 2010 passes through the housing 209 and is connected to a screw 2015. The other end of the screw 2015 is rotatably connected inside the housing 209. By configuring the motor 2010, the output shaft of the motor 2010 can be controlled to rotate, thereby driving the screw 2015 to rotate inside the housing 209.

[0042] In a specific configuration, the outer surface of the screw 2015 is threadedly connected to a threaded seat 2016, which is slidably connected inside the housing 209. The screw 2015 is configured such that when it rotates, the threaded seat 2016 moves up and down inside the housing 209.

[0043] In a specific configuration, a connecting plate 2017 is connected to one side of the threaded seat 2016, and a track plate 2011 is connected to one end of the connecting plate 2017. The threaded seat 2016 can move up and down, thereby driving the connecting plate 2017 to move up and down, and in turn, the track plate 2011 to move up and down.

[0044] In a specific configuration, multiple sets of sliding grooves 205 are provided through one side of the track plate 2011. The sliding grooves 205 enable the first slider 2012 and the second slider 2013 to slide when the track plate 2011 moves up and down.

[0045] In a specific configuration, a U-shaped component 2018 is connected to one side of the first slider 2012, and the U-shaped component 2018 is connected to one side of the second slider 2013. A protrusion 2014 is connected inside the U-shaped component 2018, and the protrusion 2014 slides inside the sliding groove 205. By setting the protrusion 2014, when the track plate 2011 moves up and down, the protrusion 2014 can be driven to slide inside the sliding groove 205, which can drive the U-shaped component 2018 to move left and right, and drive the output head 204 to move left and right. The distance between multiple sets of output heads 204 can be adjusted to adapt to different distances between grouting holes, and multiple sets of output heads 204 can be used to simultaneously grout multiple grouting holes, thereby improving the grouting efficiency of the grouting device 1.

[0046] In a specific configuration, the adjustment mechanism 3 includes multiple sets of cylinders 302, which are respectively connected to one side of the U-shaped part 2018. The output end of the cylinder 302 is connected to a moving part 301, which is sleeved on the outer surface of the second pipe 203. By controlling the cylinder 302, the moving part 301 can be moved up and down, which in turn moves the output head 204 up and down. This allows for adjustment of the insertion depth of different output heads 204 when cracks appear on the road surface.

[0047] In a specific configuration, the outer surface of the second pipe 203 is provided with an external thread 303, and the inside of the output head 204 is provided with an internal thread 304. The external thread 303 and the internal thread 304 are threadedly connected. The external thread 303 and the internal thread 304 are provided to facilitate the replacement of different models of output head 204.

[0048] In a specific configuration, a through hole 305 is provided at the bottom of the output head 204. By setting the through hole 305, different diameter through holes 305 can be opened to make the output head 204 belong to different models, and the output amount of the output head 204 can be controlled. The output head 204 with a larger diameter through hole 305 is grouted by the grouting device 1, and the output grout is more than that of the output head 204 with a smaller diameter, which can adapt to the different grout amounts required inside different grouting holes.

[0049] The working principle of this dynamic crack grouting repair device for asphalt pavement is as follows: When using the device, the motor 2010 drives the screw 2015 to rotate inside the housing 209, which in turn drives the threaded seat 2016 to move up and down inside the housing 209. When the connecting plate 2017 drives the track plate 2011 to move up and down, the protrusion 2014 slides inside the sliding groove 205, which in turn drives the U-shaped part 2018 to move left and right. This causes the first slider 2012 to slide on the outer surface of the first horizontal plate 207, and the second slider 2013 to slide on the outer surface of the second horizontal plate 208, thus driving the output head 204 to move left and right. The distance between multiple sets of output heads 204 can be adjusted to accommodate different distances between grouting holes, allowing multiple sets of output heads 204 to simultaneously grout multiple holes. The grouting device 1 improves grouting efficiency by controlling the cylinder 302 to move the moving part 301 up and down, which in turn moves the output head 204 up and down. When cracks appear in the road surface, the insertion depth of different output heads 204 can be adjusted. By opening through holes 305 of different diameters, the output heads 204 can be of different models, and the output amount of the output head 204 can be controlled. The output head 204 with a larger diameter through hole 305 outputs more grout through the grouting device 1 than the output head 204 with a smaller diameter. This can adapt to the different grout amounts required inside different grouting holes, thereby solving the problem that most existing crack grouting repair devices only have one output end and cannot grout multiple grouting holes at the same time. They need to grout each grouting hole one by one, which reduces the working efficiency of the crack grouting repair device.

[0050] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
