Technical Field

[0001] This utility model belongs to the field of road engineering equipment technology, and in particular relates to a partial road surface repair device. Background Technology

[0002] During road use, localized damage caused by vehicle loads, weather, or other factors requires timely repair to prevent further damage. After the road is filled with repair material, it needs to be flattened and compacted to ensure it adheres to the original road surface.

[0003] For example, patent number CN 211713600 U discloses a compaction device for local repair of asphalt concrete pavement, including an outer casing and a control lever arm. One end of the control lever arm is fixed to the end face of the outer casing, and the other end of the control lever arm is welded with a support frame. A diesel drive motor is installed in the middle of the upper end face of the outer casing. The output shaft of the diesel drive motor is fixed to the main pulley. A transmission belt is provided on the main pulley. The main pulley is connected to the auxiliary pulley through the transmission belt. A fixing rod is fixed on the front end face of the auxiliary pulley. A rotating sleeve is rotatably connected to the fixing rod. A connecting rod is installed inside the outer casing. A strip-shaped through hole is opened on the left side of the front end face of the connecting rod. The rotating sleeve is slidably connected in the strip-shaped through hole. A support rod is rotatably connected to the right end of the connecting rod. A pressure plate is installed on the other end of the support rod. Three rollers are installed on the lower end face of the outer casing.

[0004] In existing technologies, the addition of a compaction device makes the equipment more compact and practical, reducing resource waste and effectively compacting the road surface. However, the following problems still exist in its overall use: In existing technologies, the compaction time needs to be carefully controlled during road surface compaction; otherwise, undried asphalt will stick to the bottom of the compaction plate, affecting work efficiency. Secondly, the vibration generated during road surface compaction will shake dust into the compaction area, affecting the compaction effect. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a partial road surface repair device. By setting up a heat insulation cavity and a water tank, the interior of the compaction plate can be cooled, so that a temperature difference is formed between the surface of the compaction plate and the asphalt pavement, thereby reducing the temperature of the asphalt contact surface and preventing asphalt adhesion. By setting up an exhaust device, the surface of the asphalt to be compacted can be cleaned.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a partial road surface repair device, including a frame, a compaction box inside the frame, a liftable compaction plate slidably disposed at the bottom of the compaction box, a heat insulation cavity inside the compaction plate, multiple telescopic rods with cavities disposed on the end face of the compaction plate, a water tank disposed at the top of the telescopic rods, a cooling component disposed on the surface of the water tank, an exhaust device disposed on one side of the compaction box, and a movable plate rotatable in one direction disposed inside the exhaust device. The compaction plate arrangement allows for the regular, cyclical compaction of the asphalt pavement.

[0007] Preferably, a transmission rod is rotatably mounted inside the compaction box. Multiple short rods are mounted in the middle section of the transmission rod, and a long rod is rotatably mounted between two short rods. One end of the long rod is rotatably connected to the compaction plate. The transmission rod allows the compaction plate to rise and fall using centrifugal force.

[0008] Preferably, the top of the multiple telescopic rods is provided with multiple fixing blocks on the inner wall of the compaction box, the multiple fixing blocks are grouped in pairs, and the top of each group of fixing blocks is provided with an mounting plate, the top of the mounting plate being fixedly connected to the water tank.

[0009] Preferably, a first water pipe is provided inside the plurality of telescopic rods, one end of two of the first water pipes is fixedly connected to the inside of the heat insulation cavity, and the other end of the first water pipe is fixedly connected to the inside of the water tank.

[0010] Preferably, a circulation pump is provided on one side of the water tank on the inner wall of the compaction box, and a second water pipe is provided at each of the two output ports of the circulation pump, and multiple second water pipes are connected to the heat insulation cavity.

[0011] Preferably, a filter block is provided on one side of the exhaust component on the inner wall of the compaction chamber. The filter block can prevent soil and dust from entering the interior of the exhaust component and affecting its normal operation.

[0012] Preferably, the exhaust component has a baffle inside, which abuts against one side of the movable plate.

[0013] Preferably, the refrigeration assembly includes fan blades mounted on a transmission rod, and multiple refrigeration elements are disposed on one side of the fan blades on the surface of the water tank. The fan blades can dissipate heat from the refrigeration elements, improve air circulation within the compaction chamber, and enhance cooling efficiency.

[0014] Preferably, the bottom of the frame is provided with multiple wheels, and a push rod is provided on one side of the frame.

[0015] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0016] (1) By setting up a heat insulation cavity and a water tank, the water in the heat insulation cavity can be circulated and the water cooling can be used to cool the interior of the compaction plate, so that the surface of the compaction plate and the asphalt pavement form a temperature difference, thereby reducing the temperature of the asphalt contact surface and preventing asphalt from sticking.

[0017] (2) By setting an exhaust device, this utility model can clean the surface of the asphalt to be compacted, prevent dust and soil from falling onto the asphalt surface and affecting the compaction effect. By setting a filter block, it can prevent the compressed air from entering the exhaust device and causing the exhaust device to be blocked, thus ensuring the normal operation of the air blowing cleaning work.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0027] refer to Figure 1 , Figure 2 and Figure 3A partial road surface repair device includes a frame 1, a compaction box 2 inside the frame 1, a liftable compaction plate 3 slidably disposed at the bottom of the compaction box 2, a heat insulation cavity 4 inside the compaction plate 3, a plurality of telescopic rods 5 with cavities disposed on the end face of the compaction plate 3, a water tank 6 disposed at the top of the telescopic rods 5, a cooling component disposed on the surface of the water tank 6, an exhaust component 7 disposed on one side of the compaction box 2, and a movable plate 8 that can rotate in one direction disposed inside the exhaust component 7.

[0028] In this scheme, the compaction plate 3 can be set up to compact the asphalt ground in a regular and cyclical manner. The telescopic rods 5 are respectively placed at the four corners of the compaction plate 3. The telescopic rods 5 can limit the raising and lowering of the compaction plate 3. The inside of the telescopic rod 5 is hollow. The surface of the compaction plate 3 is provided with through holes, which are set corresponding to the telescopic rods 5. This arrangement allows the first water pipe 15 and the second water pipe to pass through the inside of the telescopic rod 5 and the compaction plate 3 to connect with the heat insulation cavity 4. This allows the water tank 6 and the circulation pump 16 to be connected through the first water pipe 15 and the second water pipe 17 to form a circular circulation, thereby allowing the water in the water tank 6 to replace the water in the heat insulation cavity 4 for cooling.

[0029] refer to Figure 2 and Figure 3 The compaction box 2 is equipped with a drive motor 9. A transmission rod 10 is mounted on the output shaft of the drive motor 9. Multiple short rods 11 are mounted in the middle section of the transmission rod 10. A long rod 12 is rotatably mounted between two short rods 11. One end of the long rod 12 is rotatably connected to the compaction plate 3. The transmission rod 10 can drive the short rods 11 and the long rod 12 to raise and lower the compaction plate 3.

[0030] In this scheme, when the drive motor 9 drives the transmission rod 10 to rotate, the transmission rod 10 will drive the two short rods 11 to rotate. The two short rods 11 will drive the middle long rod 12 to move. When the short rod 11 and the long rod 12 rotate to the highest point, the long rod 12 and the short rod 11 fold, so that the other end of the long rod 12 pulls the compaction plate 3 to rise. When the hinge of the long rod 12 and the short rod 11 is at the lowest point, the long rod 12 descends and pushes the compaction plate 3 to descend, compacting the asphalt pavement.

[0031] refer to Figure 2 and Figure 4 Multiple telescopic rods 5 are provided with multiple fixing blocks 13 on the inner wall of the compaction box 2. The multiple fixing blocks 13 are grouped in pairs. Each group of fixing blocks 13 is provided with a mounting plate 14 on its top. The mounting plate 14 is fixedly connected to the water tank 6. The multiple telescopic rods 5 are provided with first water pipes 15. One end of the two first water pipes 15 is fixedly connected to the inside of the heat insulation cavity 4, and the other end of the first water pipe 15 is fixedly connected to the inside of the water tank 6.

[0032] In this scheme, the number of telescopic rods 5 and fixed blocks 13 is equal, with four of each, forming pairs. The first water pipe 15 passes through the telescopic rods 5 and fixed blocks 13, and finally passes through the mounting plate 14 to connect with the bottom of the water tank 6, thus connecting the water tank 6 with the heat insulation cavity 4.

[0033] refer to Figure 4 A circulation pump 16 is installed on one side of the water tank 6 on the inner wall of the compaction box 2. A second water pipe 17 is installed at each of the two output ports of the circulation pump 16. Multiple second water pipes 17 are connected to the heat insulation cavity 4.

[0034] In this scheme, the second water pipe 17 passes through the mounting plate 14 and the fixing block 13 and is connected to the interior of the heat insulation cavity 4. The circulating pump 16 can make the water in the heat insulation cavity 4 flow, perform hot and cold exchange, and reduce the temperature in the heat insulation cavity 4.

[0035] refer to Figure 5 , Figure 6 and Figure 7 A filter block 18 is provided on one side of the exhaust component 7 on the inner wall of the compaction box 2, and a baffle 19 is provided inside the exhaust component 7, which abuts against one side of the movable plate 8.

[0036] In this design, one end of the exhaust component 7 is bent downwards with the air inlet pointing towards the ground. The filter block 18 prevents dirt and dust from entering the interior of the exhaust component 7 and affecting its normal operation.

[0037] refer to Figure 2 and Figure 3 The refrigeration assembly includes a fan blade 20 mounted on the transmission rod 10, and a plurality of refrigeration elements 21 are mounted on one side of the fan blade 20 on the surface of the water tank 6.

[0038] In this solution, the cooling component 21 is existing technology and will not be elaborated on further. Its main function is to dissipate heat from the water in the water tank 6 by fitting it to the water tank 6, and the fan blade 20 can promote the flow of gas and reduce the temperature inside the compaction box 2.

[0039] refer to Figure 1 The bottom of the frame 1 is provided with multiple wheels 22, and a push rod 23 is provided on one side of the frame 1.

[0040] In use, the staff pushes the push rod 23 to transport the compaction box 2 to the asphalt road surface, and then starts the drive motor 9. The output shaft of the drive motor 9 drives the transmission rod 10 to rotate. The transmission rod 10 drives the two short rods 11 to rotate. The two short rods 11 drive the middle long rod 12 to move. When the hinge between the short rod 11 and the long rod 12 rotates to the highest point, the long rod 12 and the short rod 11 fold, so that the other end of the long rod 12 pulls the compaction plate 3 to rise. When the hinge between the long rod 12 and the short rod 11 is at the lowest point, the long rod 12 descends and pushes the compaction plate 3 to descend, compacting the asphalt road surface.

[0041] During compaction, the fan blades 20 on the transmission rod 10 move with the transmission rod 10, dissipating heat from the cooling component 21 attached to the surface of the water tank 6. The cooling component 21 cools the water in the water tank 6 through heat exchange. Then, the circulation pump 16 is started, which makes the water in the insulation cavity 4 flow, exchanging heat between the water in the water tank 6 and lowering the temperature of the insulation cavity 4. After the temperature of the compaction plate 3 surface decreases, a temperature difference is formed between the compaction plate 3 and the asphalt surface. The low temperature at the bottom of the compaction plate 3 causes the asphalt surface to solidify, preventing the asphalt from sticking to the surface of the compaction plate 3.

[0042] During the operation of the compaction box 2, air will enter the compaction box 2 when the compaction plate 3 falls. When the compaction plate 3 moves up and down, it will compress the air in the compaction box 2, so that the air passes through the filter block 18 and enters the exhaust component 7. The exhaust component 7 blows air onto the road surface to carry out cleaning work.
