Description

Technical Field

[0001] This utility model relates to an asphalt pavement repair device, belonging to the technical field of asphalt pavement maintenance. Background Technology

[0002] Asphalt pavement, also commonly known as asphalt concrete road or paved road, is a common type of flexible pavement. It is mainly composed of asphalt (a petroleum refining byproduct) and aggregates (such as sand, gravel, and crushed stone). Asphalt acts as a binder, holding the aggregates together to form a strong pavement. Asphalt roads are prone to cracking due to vehicle traffic and vibrations from construction, especially near construction sites. When cracks appear, asphalt is typically used to directly fill them to repair the pavement.

[0003] Typically, during road repair work, workers move a repair device carrying asphalt to the corresponding road crack, and then the asphalt is delivered to the crack through a pipeline for repair. However, due to the high viscosity of asphalt, on the one hand, the asphalt discharge rate is slow, making it difficult to discharge and reducing the efficiency of road repair; on the other hand, during long-term repair work, the asphalt is prone to solidifying and clogging the pipeline. Utility Model Content

[0004] The purpose of this invention is to provide an asphalt pavement repair device for repairing asphalt pavements, which can increase the discharge speed of asphalt from the discharge pipe and prevent asphalt from stagnating in the discharge pipe and causing blockage.

[0005] This utility model is achieved through the following technical solution.

[0006] An asphalt pavement repair device includes a repair container for containing repair materials and a discharge pipe connected to the repair container, the discharge pipe having a discharge port; the repair container is provided with a clearing mechanism, the clearing mechanism including a driving assembly and a clearing component, the clearing component being at least partially located inside the discharge pipe, the driving assembly for driving the clearing component to rotate axially around the discharge pipe, the clearing component, when rotating, pushing the repair materials inside the discharge pipe to move axially along the discharge pipe and be output from the discharge port.

[0007] As a further improvement of this utility model, the unblocking component includes an unblocking rod that is connected to the driving assembly and a spiral blade disposed on the outer surface of the unblocking rod and at least partially located in the discharge pipe. The unblocking rod is coaxially disposed with the discharge pipe. When the unblocking rod rotates, it drives the spiral blade to rotate, thereby pushing the repair material in the discharge pipe toward the discharge port.

[0008] As a further improvement of this utility model, the axial extension range of the spiral blades at least covers the entire discharge pipe.

[0009] As a further improvement of this utility model, the drive assembly includes a driver and a rotating shaft driven by the driver to rotate. The rotating shaft is rotatably installed inside the repair container and is connected to the unblocking component.

[0010] As a further improvement of this utility model, the repair container is provided with a stirring component, which is linked to the rotating shaft. When the rotating shaft rotates, it drives the stirring component to stir the repair material in the repair container.

[0011] As a further improvement of this utility model, the stirring component is arranged to extend radially along the rotating shaft.

[0012] As a further improvement of this utility model, the inside of the repair container is provided with a scraping component for contacting the inner wall of the repair container. The scraping component is linked to the rotating shaft, so that when the rotating shaft rotates, it drives the scraping component to scrape away the repair material adhering to the inner wall of the repair container.

[0013] As a further improvement of this utility model, the end of the scraper that contacts the repair container is fitted to the inner wall of the repair container.

[0014] As a further improvement of this utility model, the repair container is connected to a conveying pipe for conveying repair materials into the interior of the repair container.

[0015] As a further improvement of this utility model, the repair container includes a container body with an opening at the top and a top cover disposed on the container body, the drive assembly is disposed on the top cover, and the container body and the top cover are detachably connected.

[0016] The beneficial effects of this utility model are:

[0017] 1. By rotating the unblocking component located inside the discharge pipe, the asphalt inside the discharge pipe is pushed to move along the axial direction of the discharge pipe and output from the discharge port. This keeps the asphalt in a flowing state, which can improve the discharge speed of the asphalt, improve the efficiency of road repair work, and prevent asphalt from stagnating in the unblocking pipe and causing blockage of the discharge pipe.

[0018] 2. The rotation of the spiral blades generates axial thrust, forcing the high-viscosity asphalt through the discharge pipe, increasing the asphalt discharge speed and improving operational efficiency. Simultaneously, the rotation of the spiral blades agitates the asphalt material, preventing it from stagnating in the discharge pipe and causing blockages.

[0019] 3. Driven by a rotating shaft, it can simultaneously perform three functions: material mixing, pipe unblocking, and inner wall cleaning, reducing energy consumption. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0026] This embodiment provides an asphalt pavement repair device for filling potholes or cracks in asphalt pavements to repair them. (Refer to...) Figures 1-3 The device includes a repair container 1 for containing repair materials and a discharge pipe 2 connecting the repair container 1. The discharge pipe 2 has a discharge port 21. The repair container 1 is provided with a clearing mechanism, which includes a drive assembly 3 and a clearing component 4. The clearing component 4 is at least partially located inside the discharge pipe 2. The drive assembly is used to drive the clearing component to rotate about the axial direction of the discharge pipe 2. When the clearing component 4 rotates, it pushes the repair materials located inside the discharge pipe 2 to move along the axial direction of the discharge pipe 2 and be discharged from the discharge port 21. In this embodiment, the repair material refers to asphalt used to repair potholes and cracks in the road surface.

[0027] In this embodiment, the asphalt inside the discharge pipe 2 is pushed to move along the axial direction of the discharge pipe by the rotation of the unblocking component 4 located inside the discharge pipe 2 and output from the discharge port 21. This can improve the discharge speed of the asphalt, improve the efficiency of road repair work, and prevent the asphalt from stagnating in the unblocking pipe and causing blockage of the discharge pipe.

[0028] Specifically, refer to Figure 3 The unblocking component 4 includes an unblocking rod 41 connected to the drive assembly 3 and a spiral blade 42 disposed on the outer surface of the unblocking rod 41 and located inside the discharge pipe 2. The spiral blade 42 is an integrally formed structure welded to the outer surface of the unblocking rod 41. The unblocking rod 41 extends into the discharge pipe 2 and is coaxially arranged with the discharge pipe 2. When the unblocking rod 41 rotates, it drives the spiral blade 42 to rotate, thereby pushing the asphalt towards the discharge port 21. Specifically, when the drive assembly 3 is working, it drives the spiral blade 42 to rotate. The rotation of the spiral blade 42 generates axial thrust, allowing the high-viscosity asphalt to pass through the discharge pipe 2, increasing the discharge speed of the asphalt and thus improving work efficiency. At the same time, the rotation of the spiral blade 42 can agitate the asphalt material, preventing the asphalt from stagnating in the discharge pipe 2 and causing blockage.

[0029] It should be noted that, referring to Figure 3 The unblocking rod 41 rotates from right to left, and the spiral surface of the spiral blade 42 extends from right to left and tilts towards the discharge port 21. Therefore, when the unblocking rod 41 rotates under the drive of the drive assembly 3, the spiral blade 42 rotates and drives the asphalt to move along the axial direction of the discharge pipe 2 and towards the discharge port 21, and finally discharges it from the discharge port 21.

[0030] In addition, the spiral blade 42 extends along the axial direction to cover at least the entire discharge pipe 2. Preferably, the spiral blade 42 extends from the inside of the repair container 1 to the discharge port 21 of the discharge pipe 2. At the same time, the unblocking rod 41 also extends into the discharge port 21 of the discharge pipe 2, thereby achieving unblocking of the entire discharge pipe 2 without dead angles.

[0031] In this embodiment, refer to Figure 2 The drive assembly 3 includes a driver 31 and a rotating shaft 32 driven by the driver 31. The rotating shaft 32 is vertically arranged and rotatably installed inside the repair container 1. The rotating shaft 32 is connected to the unblocking component 4, and its lower end is connected to one end of the unblocking rod 41 and is coaxially arranged with the unblocking rod 41. The rotating shaft 32 is coaxially arranged with the repair container 1. When the drive assembly 3 is working, the driver 31 drives the rotating shaft 32 to rotate, which in turn drives the unblocking rod 41 to rotate synchronously, causing the spiral blades 42 installed on the outer surface of the unblocking rod 41 to rotate. When the spiral blades 42 rotate, they push the asphalt to move, thereby pushing the asphalt out of the discharge port 21. It should be noted that the driver 31 is installed on the surface of the repair container 1, and the rotating shaft 32 can be rotatably connected to the repair container 1 through bearings to ensure the stable rotation of the rotating shaft 32 on the repair container 1. Here, the driver 31 is set as a servo motor or a geared motor.

[0032] In this embodiment, since asphalt is mainly used for road repair, and asphalt tends to solidify after a certain period of time, when using this device for road repair, if there is a large amount of asphalt in the repair container 1, the asphalt may solidify inside the container, causing blockage of the discharge pipe 2. To solve this problem, a stirring component 5 is provided inside the repair container 1. The stirring component 5 is linked to the rotating shaft 32, so that when the rotating shaft 32 rotates, it drives the stirring component 5 to rotate to stir the asphalt in the repair container 1. Specifically, the stirring component 5 is connected to the rotating shaft 32. Therefore, when the rotating shaft 32 rotates, the stirring component 5 rotates synchronously under the drive of the rotating shaft 32 to achieve stirring of the asphalt in the repair container 1. Furthermore, to stir the asphalt more efficiently, the stirring component 5 extends radially along the rotating shaft 32, so that the stirring component 5 has a larger contact area with the asphalt, improving the stirring efficiency. In addition, the number of stirring components 5 can be set to one or more, and the specific number can be determined according to the volume of the repair container 1 to stir the asphalt more evenly and efficiently.

[0033] In this embodiment, the interior of the repair container 1 is equipped with a scraping component 6 for contacting the inner wall of the repair container 1. The scraping component 6 is linked to the rotating shaft 32, so that when the rotating shaft 32 rotates, it drives the scraping component 6 to rotate, thereby scraping away the asphalt adhering to the inner wall of the repair container 1, achieving cleaning of the inner wall of the repair container 1. The scraping component 6 can scrape away the asphalt adhering to the inner wall of the container, which can reduce asphalt waste, save costs, and reduce subsequent maintenance time. Furthermore, in order to scrape away the asphalt adhering to the inner wall of the repair container 1 more effectively, the end of the scraping component 6 that contacts the repair container 1 is fitted to the inner wall of the repair container 1, thereby enabling more effective scraping away of the asphalt adhering to the inner wall of the repair container 1.

[0034] It should be noted that the stirring component 5 and the scraping component 6 can be connected via the drive shaft 7, or the stirring component 5 and the scraping component 6 can be directly connected to the rotating shaft 32. When using the drive shaft 7 to connect the stirring component 5 and the scraping component 6, refer to... Figure 2 A connecting piece 8 is rotatably mounted on the rotating shaft 32. Both drive shafts 7 are connected to the connecting piece 8. The axis of the drive shaft 7 is parallel to the axis of the rotating shaft 32. The two drive shafts 7 are respectively connected to the stirring component 5 and the scraping component 6. This structure facilitates the installation of the stirring component 5 and the scraping component 6.

[0035] In this embodiment, the three functions of material mixing, pipe unblocking, and inner wall cleaning can be completed simultaneously under the drive of the rotating shaft, reducing energy consumption.

[0036] In this embodiment, the repair container 1 includes a container body 11 with an opening at the top and a top cover 12 disposed on the container body 11. The drive assembly 3 is disposed on the top cover 12, and the container body 11 and the top cover 12 are detachably connected. The two can be connected by bolts or buckles. Furthermore, the top cover 12 is provided with a mounting bracket, which is composed of multiple mounting plates 33. The drive unit 31 is mounted on the mounting bracket, so that the drive unit 31 and the top cover 12 form an integral unit. Therefore, when maintaining this device, the drive assembly 3, the stirring component 5, the scraping component 6, and the unblocking component 4 can be separated from the container body 11 by disassembling the top cover 12, making maintenance convenient.

[0037] In this embodiment, a delivery pipe 9 is connected to the repair container 1 for delivering asphalt into the interior of the repair container 1, that is, external asphalt can enter the repair container 1 through the delivery pipe.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
