Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement repair technology, specifically to a rapid pavement repair device. Background Technology

[0002] Asphalt pavement is a road surface constructed by mixing mineral materials (such as crushed stone and sand) with asphalt binders (such as petroleum asphalt and modified asphalt). It is flexible and waterproof, and is widely used in highways and urban roads. During use, asphalt pavements may develop cracks or potholes, affecting their service life and road safety. Regular repairs of cracks and potholes are necessary.

[0003] For example, Chinese Patent 202021775013.3 discloses a device for repairing potholes in asphalt pavement, including a mobile cart, a material storage component, a melting component, a dust collection component, and a lifting and compaction component. The dust collection component includes a vacuum cleaner and a dust collection pipe. In use, when the mobile cart is located at one end of the pothole in the asphalt pavement, the vacuum cleaner is turned on to remove the dust from the pothole. When the blowtorch is aimed at the pothole, the blowtorch is turned on to melt the asphalt in the pothole. The asphalt is then discharged through the discharge pipe to repair the pothole. The compaction roller is then driven by a cylinder to compact the repaired asphalt. Because the melted asphalt has a high adhesion, it effectively improves the problem of poor repair results caused by cracks between the repaired asphalt pavement and the filler asphalt due to the low adhesion between the asphalt pavement and the filler asphalt.

[0004] In the aforementioned existing technologies, the width of the asphalt filling material for the repair device is generally fixed and needs to be manually adjusted to fill the gaps or potholes. Because the width of the asphalt filling material does not match the width of the gaps or potholes well, it is easy to cause incomplete filling or waste of raw materials. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To address the technical problem of incomplete filling or material overflow and waste caused by poor matching between the width of the asphalt filling material and the width of the gaps or potholes, this utility model provides a rapid road repair device. It enables the installation of a spreading mechanism within the discharge cylinder of a hot-melt container. This spreading mechanism, with its telescopic mechanism, sleeve, opening and closing mechanism, and unloading plate, forms an adjustable filling opening. The width of the filling opening is adjusted according to the width of the gaps or potholes, ensuring a proper fit. Furthermore, a flattening component smooths the filling area, improving filling quality and preventing material overflow and waste.

[0031] It should be noted that the road surface rapid repair device described in this utility model is used for, but not limited to, asphalt pavement. For ease of explanation, this utility model only uses the application of the road surface rapid repair device to asphalt pavement as an example for explanation. The principle of the road surface rapid repair device applied to other types of equipment is essentially the same as that applied to asphalt pavement, and will not be described in detail here.

[0032] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a rapid road repair device according to an embodiment of the present invention. The rapid road repair device includes a hot melt container 1 and a paving mechanism 2. The bottom of the hot melt container 1 is provided with a discharge cylinder 101 for discharging hot melt asphalt, which is used to discharge the hot melt asphalt from the discharge cylinder 101. The paving mechanism 2 includes a telescopic mechanism 21, a sleeve 22, an opening and closing mechanism 23, and a discharge plate 24. The telescopic mechanism 21 is installed on the hot melt container 1 and has a telescopic end connected to the sleeve 22, which is used to lift and lower the sleeve 22, the opening and closing mechanism 23, the discharge plate 24, and the paving piece 25 as a whole, so that they fit against the asphalt road surface to be repaired. The sleeve 22 is sleeved on the outside of the discharge cylinder 101, and the inner side of the sleeve 22 is provided with a sealing ring for sealing, forming a channel with the discharge cylinder 101 to guide the flow of hot melt asphalt. The opening and closing mechanism 23 is installed on the sleeve 22 and has a telescopic end connected to the unloading plate 24. It drives the unloading plate 24 to move relative to the sleeve 22, forming an adjustable-width filling port 201 at the bottom of the sleeve 22. It has a completely closed blocking state for the bottom of the sleeve 22, closing the filling port 201. During the movement, the filling port 201 of different widths is opened according to different moving positions.

[0033] Furthermore, the paving mechanism 2 also includes a paving component 25, which is installed on the sleeve along the repair movement direction for smoothing the asphalt pavement and scraping the hot melt asphalt filled into the gaps or potholes.

[0034] Specifically, under the extension and retraction action of the opening and closing mechanism 23, the unloading plate 24 is moved to adjust the width of the filling port 201 to match the width of the corresponding gap or pit. The hot-melted asphalt enters the sleeve 22 from the discharge cylinder 101 and flows to the filling port 201, finally filling the gap or pit.

[0035] Understandably, the hot melt container 1 can be a single container tank, into which hot melt asphalt is directly poured and then filled into the gaps or potholes of the asphalt pavement through the discharge cylinder 101 and the paving mechanism 2; alternatively, an existing container tank with a heating function that can directly heat the asphalt raw material to a hot melt state can be used, into which unheated asphalt is poured and heated to a hot melt state, and then filled into the gaps or potholes of the asphalt pavement through the discharge cylinder 101 and the paving mechanism 2.

[0036] In this embodiment, please refer to Figure 3 To heat the asphalt raw material to a molten state, the hot-melt container 1 includes an outer cylinder 11, a heating assembly 12, an inner cylinder 13, and a stirring mechanism 14. The inner cylinder 13 is located inside the outer cylinder 11 and serves as the portion for containing the asphalt. The top of the inner cylinder 13 has a feed inlet and a smoke outlet, used for feeding the asphalt raw material into the inner cylinder 13 and for discharging the smoke generated during hot melting, respectively. The heating assembly 12 is located between the inner cylinder 13 and the outer cylinder 11 and is used to heat the inner cylinder 13 to melt the asphalt. The stirring mechanism 14 is mounted on the outer cylinder 11 and has a rotatable stirring end 141 that is inserted into the inner cylinder 13. The stirring end 141 extends downward to the inner side of the sleeve 22 for stirring the hot-melt asphalt.

[0037] It is understandable that the specific structure of the above-mentioned hot melt container 1 is only one feasible structural composition for heating and melting asphalt. Other existing mature asphalt hot melt equipment can also be used, and no single limitation is made here.

[0038] It should be noted that the heating component 12 can be an electric heating tube, which is evenly distributed on the outside of the inner cylinder 13 to provide heating; the stirring mechanism 14 can be a drive motor and a stirring paddle, with the stirring paddle installed on the output shaft of the drive motor, and the stirring end being the stirring paddle. The drive motor drives the stirring paddle to rotate, stirring the asphalt material in the inner cylinder 13 in a hot melt state.

[0039] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3To lift and lower the sleeve 22, opening and closing mechanism 23, unloading plate 24, and paving piece 25 as a whole, and to press the unloading plate 24 and paving piece 25 onto the asphalt pavement, the telescopic mechanism 21 includes a lifting telescopic component 211 and an elastic component 212. At least one lifting telescopic component 211 is installed on the hot melt container 1, and the elastic component 212 is installed between the telescopic end of the lifting telescopic component 211 and the sleeve 22. By extending and retracting the lifting telescopic component 211, the sleeve 22 can be raised and lowered, thereby lifting and lowering the sleeve 22, opening and closing mechanism 23, unloading plate 24, and paving piece 25 as a whole. The elastic component 212, acting as an intermediate connector, provides elastic compression space and, under compression, provides a rebound force, allowing the unloading plate 24 and paving piece 25 to press onto the asphalt pavement.

[0040] Specifically, there are two lifting telescopic components 211, which provide a relatively balanced lifting action. The two lifting telescopic components 211 are arranged on both sides of the discharge cylinder 101, with their bottom ends being telescopic ends, and both are fixedly connected to the sleeve 22 to lift and lower the sleeve 22, so that the sleeve 22 extends and retracts relative to the discharge cylinder 101.

[0041] Understandably, the elastic element 212 can be an elastic element that provides elastic support and can be compressed and reset, such as a spring or an elastic rubber pad.

[0042] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 In order to control the opening width of the filling port 201, the opening and closing mechanism 23 includes a longitudinal telescopic member 231 and a connecting frame 232. At least one of the longitudinal telescopic members 231 is installed on the sleeve 22. The telescopic end of the longitudinal telescopic member 231 is connected to the connecting frame 232, and the other end of the connecting frame 232 is connected to the unloading plate 24. The longitudinal telescopic member 231 drives the connecting frame 232 and the unloading plate 24 to move together, moving radially along the sleeve 22, thereby controlling the width of the opening of the filling port 201.

[0043] Specifically, when there is only one longitudinal telescopic component 231, there is also only one corresponding unloading plate component 24. One unloading plate component 24 covers the bottom end of the entire sleeve 22. By moving the plate, the bottom space of the sleeve 22 is gradually opened, which is the filling port 201. When there are two longitudinal telescopic components 231, there are also two unloading plate components 24. The two unloading plate components 24 move closer to each other or move away from each other. When they are close together, the filling port 201 is closed. Conversely, the filling port 201 can be gradually opened.

[0044] Furthermore, for specific filling, the unloading plate 24 includes a first plate 241, a second plate 242, and an inclined plate 243. The top and bottom of the inclined plate 243 are connected to the first plate 241 and the second plate 242, respectively. The first plate 241 abuts against the bottom end of the sleeve 22, and the second plate 242 abuts against the ground. The first plate 241 blocks the bottom end of the sleeve 22, the second plate 242 controls the opening and closing degree of the filling port 201, and the inclined plate 243 guides the asphalt to flow to the filling port 201.

[0045] Furthermore, in order to trap excess asphalt within the discharge plate 24 during closure, there are two discharge plates 24, with the inclined surfaces of the two inclined plates 243 facing each other and both pointing towards the discharge cylinder 101. During clamping, the asphalt can be guided to move up the inclined surfaces, and finally, during closure, the amount of asphalt remaining in the gaps or pits is reduced.

[0046] In addition, the sleeve 22 is provided with an outer edge plate 221 that abuts against the top of the first plate 241 to cover the top of the unloading plate 24.

[0047] Correspondingly, there are two flattening pieces 25, which are arranged on both sides of the unloading plate 24 along the repair movement direction, and can cover the front and rear sides of the two unloading plate 24.

[0048] Understandably, the outer edge plate 221 and the flat piece 25 provide a basic fitting and shielding function during the movement of the unloading plate 24, and sealing strips can be set at their contact points to prevent asphalt from overflowing from the top or front and rear sides.

[0049] Furthermore, the flat component 25 is L-shaped and has a transparent plate 251. Through the transparent plate 251, it is possible to observe whether the filling is in place while the device is moving. If it is not in place, it can be moved repeatedly in this area to make it fill in place.

[0050] In one embodiment, please refer to Figure 1 To facilitate movement of the device, a moving mechanism 3 is also included. The moving mechanism 3 is mounted on the hot melt container 1 and has a moving end for moving the hot melt container 1. The moving mechanism 3 employs at least two wheels rotatably connected to the hot melt container 1 to provide movement functionality.

[0051] It is understandable that the moving mechanism 3 may also use wheels driven by a motor, and this is not the only limitation. Furthermore, when the moving mechanism 3 is not present, and the hot melt container 1 is used to directly pour the hot melt asphalt, the overall weight is lighter, and the hot melt container 1 and the spreading mechanism 2 can be moved together directly.

[0052] In one embodiment, please refer to Figure 1To facilitate manual movement of the device, a pusher 4 is included, which is mounted on the hot melt container 1 for manually pushing the entire device. Furthermore, the bottom of the pusher 4 is equipped with a support foot to provide support to the ground when not in use.

[0053] It should be noted that both the lifting telescopic component 211 and the longitudinal telescopic component 231 can be hydraulic push rods.

[0054] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail as follows: The unloading plate 24 and the paving piece 25 are lowered by the lifting telescopic component 211 to make them flat against the asphalt pavement. The width of the filling opening 201 is adjusted by the extension and retraction of the longitudinal telescopic component 231 to match the width of the gaps or potholes. The asphalt pavement filler is then put into the hot melt container 1 for hot melting. The hot melted asphalt is discharged through the discharge cylinder 101 into the sleeve 22, and then enters the gaps or potholes of the asphalt pavement through the filling opening 201. The device is pushed to move, and the paving piece 25 has a leveling effect. The transparent plate 251 is observed simultaneously until the gaps and potholes are filled in place, which can provide a fast repair effect. When the two unloading plates 24 move to the closed position, they also separate the excess hot melted asphalt from the ground to avoid waste caused by it remaining outside.

[0055] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
