Description

Technical Field

[0001] This invention relates to the technical field of road repair equipment, specifically to a method for rapid repair of lightweight asphalt pavements. Background Technology

[0002] In Building Information Modeling (BIM), lightweighting utilizes techniques such as model panelization, cloud-based information processing, and logical simplification to streamline, transform, and reduce the model's geometric entities, information carrying capacity, and construction logic. Cracks have become one of the most significant early-stage defects in asphalt pavements, severely impacting their performance and service life.

[0003] Chinese invention patent CN110616627A, entitled "A Rapid Repair Device for Asphalt Pavement Cracks," describes a device that uses a drive motor to rotate an extrusion screw, which in turn causes an extrusion baffle to squeeze the storage cylinder. This allows the repair material to flow at a uniform speed within a heated spiral coil. If heating is required, the repair material can be heated via an electric heating element to heat the heat transfer medium. The uniform movement of the repair material, combined with the heat transfer through the heat transfer medium, effectively ensures a constant temperature for the repair material, thus allowing for precise temperature control and resulting in better repair performance for pavement cracks. This device is also applicable to a variety of repair materials.

[0004] The above-mentioned device has some shortcomings. It is not convenient to adjust the heated asphalt to the specified size. It is easy to cause the asphalt to be poured onto the crack, flattened, and then the excess asphalt to be manually cleaned up, which affects the efficiency of road repair. Therefore, a lightweight asphalt pavement rapid repair method that can solve the above problems is proposed. Summary of the Invention

Then, the adjustment plate is pulled to adjust the width of the asphalt block extruded from the outlet. After adjustment, the operating rod is released, and the operating rod, under the elastic force of the first spring, drives the limiting post to be inserted into the limiting hole. Then, the electric telescopic plate is started to adjust the thickness of the asphalt block extruded from the outlet. The extrusion component operates once to drive the cutting blade to cut the asphalt block into small pieces, which is convenient for repairing cracks and avoids the situation of asphalt overflowing and wasting when repairing cracks. This helps to improve the work efficiency of the repair staff.

[0022] (3) The extrusion assembly drives the extrusion plate to move backward through the first electric telescopic rod, and at the same time, the asphalt in the asphalt tank enters between the extrusion plate and the inner wall of the asphalt tank through the rectangular through hole. Then, the first electric telescopic rod drives the extrusion plate to extrude the asphalt, and the blocking plate blocks the rectangular through hole under the reverse force of the asphalt. The extension plate drives the limiting plate to extrude the third spring, and at the same time, the extension plate retracts into the receiving groove, which makes it easier to squeeze the asphalt out of the discharge port. At the same time, the extrusion plate drives the cutting blade to move up and down through the pull rope, which makes it easier to cut the asphalt block. This is beneficial to improving the working efficiency of the device, making it easier to adjust the size of the regular asphalt block, and improving the flexibility and applicability of the device.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 - Figure 7 As shown, the present invention is a method for rapid repair of lightweight asphalt pavement, comprising the following steps;

[0034] Step 1: First, use an electric saw to cut the cracks on the road surface into regular rectangles. Then clean the dust inside the cracks to ensure that the asphalt blocks adhere tightly to the road surface.

[0035] Step Two: Repair the cracks using an asphalt pavement rapid repair device. Adjust the outlet of the asphalt tank 3 on the rapid asphalt pavement rapid repair device to match the size of the crack, then place the asphalt block extruded from the asphalt tank 3 into the cut crack, and finally flatten the asphalt block on the road surface. This facilitates rapid repair of the crack and avoids the need for manual cleaning of excess asphalt after pouring it onto the crack and flattening it. This makes it easier to repair the road surface quickly and improves the efficiency of road repair work.

[0036] The rapid asphalt pavement repair device includes a base 1, on which an asphalt tank 3 is fixedly installed. The asphalt tank 3 contains boiled asphalt granules. A conveyor belt 2 is rotatably installed at the end of the base 1 away from the asphalt tank 3. The conveyor belt 2 facilitates the transport of the asphalt blocks extruded from the asphalt tank 3 to the crack. An adjustment component 5 is provided on the asphalt tank 3. The adjustment component 5 includes an adjustment plate 52. An adjustment through hole 51 is opened on the side of the asphalt tank 3 near the conveyor belt 2. A discharge port is opened on the side of the asphalt tank 3 near the conveyor belt 2. The adjustment through hole 51 is located on the inner walls on both sides of the discharge port. The adjustment plate 52 is slidably installed in the adjustment through hole 51 to facilitate the adjustment of the discharge port size. Support plates 53 are fixedly installed on both sides of the asphalt tank 3. An operating lever 54 is provided. A connecting plate 56 is fixedly installed on one end of the operating lever 54 near the adjusting plate 52. A first spring 55 is fixedly installed on the side of the connecting plate 56 near the operating lever 54. The first spring 55 serves to elastically reset the connecting plate 56, facilitating the insertion of the limiting post 57 into the limiting hole 59, thus stabilizing the position of the adjusting plate 52 within the adjusting through hole 51 and facilitating adjustment of the discharge port size. The limiting post 57 is fixedly installed on the side of the connecting plate 56 away from the first spring 55. A limiting hole 59 is provided on the adjusting plate 52, and the limiting post 57 inserted into the limiting hole 59 serves to stabilize the adjusting plate 52. The asphalt tank 3 is equipped with a cutting assembly 6 and an extrusion assembly 7. The first spring 55 is located away from the first spring 55. One end of the connecting plate 56 is fixedly installed on the support plate 53. The first spring 55 is nested on the outer surface of the operating rod 54. The operating rod 54 serves to limit and stabilize the first spring 55. There are multiple limiting holes 59. The limiting post 57 is inserted into the limiting hole 59. An electric telescopic plate 58 is fixedly installed on the inner wall of the adjusting through hole 51 away from the base 1. The electric telescopic plate 58 serves to adjust the thickness of the asphalt block. A heat dissipation rack 4 is fixedly installed on the side of the base 1 near the conveyor belt 2. A fan 8 is fixedly installed on the heat dissipation rack 4. The fan 8 facilitates the cooling of the extruded asphalt block, making it easy for workers to pick it up and place it into the treated crack. Two fixing blocks 9 are fixedly installed on the side of the heat dissipation rack 4 away from the asphalt tank 3. Two fixed blocks 9 are fixedly installed with second electric telescopic rods 10 on one side near the base 1. A cutting line 11 is fixedly installed between the two second electric telescopic rods 10. The second electric telescopic rods 10 drive the cutting line 11 to be flush with the conveyor belt 2. The asphalt block slides over the cutting line 11 under the drive of the conveyor belt 2, making it easy for the cutting line 11 to remove the asphalt block from the conveyor belt 2, and minimizing the situation where the asphalt block sticks to the conveyor belt 2. When using the device, first start the conveyor belt 2, then pour the asphalt into the asphalt tank 3 for heating, and then pull the operating rod 54, so that the operating rod 54 drives the connecting plate 56 to squeeze the first spring 55, so that the first spring 55 is in a compressed state. At the same time, the connecting plate 56 drives the limiting post 57 to be removed from the limiting hole 59.Then, pull the adjusting plate 52 to adjust the width of the extruded asphalt block at the outlet. After adjustment, release the operating rod 54, so that the operating rod 54, under the elastic force of the first spring 55, drives the limiting post 57 to be inserted into the limiting hole 59. Then, start the electric telescopic plate 58 to adjust the thickness of the extruded asphalt block at the outlet. The asphalt block is transported on the conveyor belt 2 past the fan 8 for heat dissipation and molding. Then, start the second electric telescopic rod 10, so that the second electric telescopic rod 10 drives the cutting line 11 to be flush with the conveyor belt 2. The asphalt block slides over the cutting line 11 under the drive of the conveyor belt 2, making it easy for the cutting line 11 to remove the asphalt block from the conveyor belt 2. The extrusion component 7 operates once to drive the cutting blade 66 to cut the asphalt block into small pieces, which is convenient for repairing cracks and minimizes the waste caused by asphalt overflow during crack repair, thus improving the work efficiency of the workers.

[0037] The extrusion assembly 7 includes an extrusion plate 73. A support column 71 is fixedly installed on the side of the base 1 away from the conveyor belt 2. A first electric telescopic rod 72 is fixedly installed on the side of the support column 71 close to the asphalt tank 3. The extrusion plate 73 is fixedly installed on the end of the first electric telescopic rod 72 away from the support column 71. The extrusion plate 73 is slidably installed inside the asphalt tank 3. The first electric telescopic rod 72 pushes the extrusion plate 73 to slide inside the asphalt tank 3, which facilitates the extrusion of asphalt from the outlet of the asphalt tank 3.

[0038] A leak-proof plate 76 is fixedly installed at the end of the extrusion plate 73 away from the base 1. The leak-proof plate 76 prevents asphalt from leaking from above the extrusion plate 73 during the extrusion process, thus forming asphalt blocks. A receiving groove 77 is provided on the leak-proof plate 76, and an extension plate 78 is slidably installed in the receiving groove 77. The extension plate 78 drives a limiting plate 79 to slide in the receiving groove 77. The limiting plate 79 is fixedly installed on the side of the extension plate 78 near the receiving groove 77, and the limiting plate 79 limits and stabilizes the extension plate. The function of 78 is as follows: A third spring 710 is fixedly installed on the side of the limiting plate 79 away from the extension plate 78. The third spring 710 plays the role of elastically resetting the extension plate 78. The end of the third spring 710 away from the limiting plate 79 is fixedly installed on the inner wall of the receiving groove 77. Rectangular through holes 74 are opened on the extrusion plate 73. There are multiple rectangular through holes 74. A baffle plate 75 is rotatably installed in the rectangular through holes 74. When the extrusion plate 73 is retracted, the asphalt in the asphalt tank 3 enters the extrusion plate 73 through the rectangular through holes 74. Between the inner walls of the asphalt tank 3, when the first electric telescopic rod 72 drives the extrusion plate 73 to extrude asphalt, the baffle plate 75 blocks the rectangular through hole 74 under the reverse force of the asphalt, thus preventing asphalt leakage. When using the device, firstly, start the first electric telescopic rod 72 to drive the extrusion plate 73 to move backward, and at the same time, let the asphalt in the asphalt tank 3 enter between the extrusion plate 73 and the inner wall of the asphalt tank 3 through the rectangular through hole 74. Then, the first electric telescopic rod 72 drives the extrusion plate 73 to extrude asphalt, and the baffle plate 75 blocks the rectangular through hole 74 under the reverse force of the asphalt. At the same time, the extrusion plate 73 drives the leak-proof plate 76 and the extension plate 78 to move towards the inner wall of the asphalt tank 3, so that the extension plate 78 is subjected to the reverse force to drive the limiting plate 79 to squeeze the third spring 710, so that the third spring 710 is in a compressed state. At the same time, the extension plate 78 retracts into the receiving groove 77, which facilitates the extrusion of asphalt from the discharge port. This facilitates the extrusion of asphalt, improves the working efficiency of the device, facilitates the adjustment of the size of the regular asphalt blocks, and improves the flexibility and applicability of the device.

[0039] The cutting assembly 6 includes a cutting blade 66. A fixing plate 61 is fixedly installed on the side of the asphalt tank 3 near the conveyor belt 2. A stabilizing rod 63 is slidably installed on the fixing plate 61, which serves to stabilize and balance the mounting plate 65. The mounting plate 65 is fixedly installed on the end of the stabilizing rod 63 near the base 1. The cutting blade 66 is fixedly installed on the side of the mounting plate 65 away from the stabilizing rod 63. A pull rope 62 and a second spring 64 are fixedly installed on the side of the mounting plate 65 near the stabilizing rod 63. The second spring 64 serves to elastically reset itself. The end of the second spring 64 away from the mounting plate 65 is fixedly installed on the fixing plate 61. The second spring 64 is nested on the outer surface of the stabilizing rod 63. The end of the pull rope 62 away from the mounting plate 65 slides through the asphalt tank 3, and the other end is fixedly installed on the extrusion plate 7. 3. The pull rope 62 facilitates the pulling of the mounting plate 65, driving the cutting blade 66 upward. The up-and-down movement of the cutting blade 66 facilitates the cutting of asphalt blocks. When using the device, when the first electric telescopic rod 72 drives the extrusion plate 73 to move backward, the extrusion plate 73 pulls the pull rope 62, which in turn drives the mounting plate 65 and the cutting blade 66 upward. At the same time, the mounting plate 65 compresses the second spring 64 and the stabilizing rod 63, causing the stabilizing rod 63 to slide on the fixed plate 61. Simultaneously, the second spring 64 is in a compressed state. Then, when the extrusion plate 73 extrudes the asphalt, the cutting blade 66 also falls. When the extrusion plate 73 presses against the inner wall of the asphalt tank 3, the cutting blade 66 cuts the asphalt block into pieces, facilitating the repair of road cracks and the cutting of asphalt blocks, thus improving the repair efficiency of the device.

[0040] The working principle of this invention is as follows: When using the device, the cracks on the road surface are first cut into regular rectangles using an electric saw. Then, the dust inside the cracks is cleaned to facilitate a tight fit between the asphalt blocks and the road surface. Next, the conveyor belt 2 is started, and asphalt is poured into the asphalt tank 3 for heating. Then, the operating lever 54 is pulled, causing the operating lever 54 to drive the connecting plate 56 to compress the first spring 55, putting the first spring 55 in a compressed state. At the same time, the connecting plate 56 causes the limiting post 57 to be removed from the limiting hole 59. Finally, the adjusting plate 52 is pulled to adjust the width of the asphalt blocks extruded from the discharge port. Adjust and release the operating lever 54 so that the operating lever 54, under the elastic force of the first spring 55, drives the limiting post 57 to be inserted into the limiting hole 59. Then, start the electric telescopic plate 58, and then start the first electric telescopic rod 72 to drive the extrusion plate 73 to move backward. At the same time, the asphalt in the asphalt tank 3 enters the space between the extrusion plate 73 and the inner wall of the asphalt tank 3 through the rectangular through hole 74. Then, the first electric telescopic rod 72 drives the extrusion plate 73 to extrude the asphalt. Under the reverse force of the asphalt, the blocking plate 75 blocks the rectangular through hole 74. At the same time, the extrusion plate 73 drives the leak-proof plate 76 and the extension plate 78 to move. The extension plate 78 is subjected to a reverse force against the inner wall of the asphalt tank 3, causing the limiting plate 79 to compress the third spring 710, thus compressing the third spring 710. Simultaneously, the extension plate 78 retracts into the receiving groove 77, facilitating the extrusion of asphalt from the outlet. The first electric telescopic rod 72 drives the extrusion plate 73 backward, pulling the pull rope 62. The pull rope 62 then drives the mounting plate 65 and the cutting blade 66 upward, causing the mounting plate 65 to compress the second spring 64 and the stabilizing rod 63. The stabilizing rod 63 slides on the fixed plate 61, while the second spring 64... 4 is in a compressed state. When the extrusion plate 73 extrudes the asphalt, the cutting blade 66 also falls. When the extrusion plate 73 extrudes the asphalt into the inner wall of the asphalt tank 3, the cutting blade 66 cuts the asphalt block into pieces. The asphalt blocks are transported on the conveyor belt 2 and pass through the fan 8 for heat dissipation and molding. Then, the second electric telescopic rod 10 is activated, so that the second electric telescopic rod 10 drives the cutting line 11 to be flush with the conveyor belt 2. The asphalt block slides over the cutting line 11 under the drive of the conveyor belt 2, so that the cutting line 11 can easily remove the asphalt block from the conveyor belt 2. Finally, the asphalt block is flattened on the road surface, which facilitates the rapid repair of cracks.

[0041] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
