Description

Technical Field

[0001] This invention relates to the field of highway construction technology, specifically to a crack repair device for highway engineering. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials into mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. However, as the pavement is used for a longer period of time, cracks and irregular potholes will appear on the asphalt pavement. If they are not repaired in time, the damaged area will expand rapidly and affect the safe passage of vehicles.

[0003] In related technologies, when filling cracks in highway pavements, a single gravity feeding or simple spiral pushing structure is usually used to transport the filling material. However, this makes it difficult to accurately match the actual volume requirements of the cracks, resulting in the filling material overflowing and causing material waste. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a crack repair device for highway engineering, which solves the problem in related technologies where the use of a single gravity feeding or simple spiral pushing structure to transport crack filling material results in material overflow and waste.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a crack repair device for highway engineering, comprising a base plate, a mixing tank fixed to the upper surface of the base plate, a heating plate sleeved on the outer wall of the mixing tank, and the lower surface of the heating plate fixed to the upper surface of the base plate, a motor fixed to the upper surface of the mixing tank, a mixing rod fixedly mounted at the output end of the motor, a cleaning component mounted on the outer wall of the bottom end of the mixing rod, and a fixing box fixed to the inner wall of the base plate, wherein the fixing box is connected to the mixing tank and the heating plate via a pipe. The inner wall of the fixing box is slidably fitted with a push-pull plate. A first elastic element is fixed between the lower surface of the push-pull plate and the inner wall of the fixing box.

The outer wall of the connecting plate is fixed to the outer wall of the hollow rod. A limit rod slides along the inner wall of the hollow rod. A fixing plate is fixed to the lower surface of the limit rod. A caulking assembly is provided on the lower surface of the base plate.

[0006] The above solution involves heating the mixing tank with a heating plate when repairing cracks. The material is then poured into the mixing tank, the motor is started to drive the mixing rod, and the equipment is pushed above the crack. At this point, the electric push rod is activated to push and pull the connecting plate, causing the connecting plate to move the hollow rod and the push-pull plate synchronously. When the push-pull plate reciprocates with the first elastic element, as it slides upwards, the sealant is pushed out and discharged through the left-side pipe of the fixed box. This method effectively controls the material output for sealing while preventing material waste.

[0007] Preferably, the caulking assembly includes a hopper, the upper surface of which is slidably connected to the lower surface of the base plate, the outer wall of which is fixedly connected to the outer wall of the fixing plate, and a support block is fixedly connected to the upper surface of the base plate.

[0008] Preferably, a handle is fixedly connected to the inner wall of the support block, a telescopic block is slidably connected to the lower outer wall of the base plate, a flattening roller is rotatably connected to the inner wall of the telescopic block, and a rotating rod is slidably connected to the inner wall of the support block.

[0009] Preferably, the outer wall of the rotating rod is rotatably connected to an elastic telescopic rod, the bottom outer wall of the elastic telescopic rod is rotatably connected to the inner wall of the base plate, and the outer wall of the rotating rod is rotatably connected to a push-pull rod, the outer wall of the push-pull rod being slidably connected to the inner wall of the base plate.

[0010] Preferably, a right-angle rod is fixedly connected to the lower surface of the push-pull rod, the outer wall of the right-angle rod is slidably connected to the inner wall of the base plate, the outer wall of the right-angle rod is slidably connected to the inner wall of the hopper, and an inclined block is fixedly connected to the outer wall of the right-angle rod, the inclined outer wall of the inclined block is slidably connected to the inner wall of the hopper.

[0011] Preferably, a sliding rod is slidably connected to the inner wall of the hopper, a guide block is fixedly connected to the outer wall of one end of the sliding rod, the outer wall of the guide block is slidably connected to the inner wall of the hopper, a fitting piece is fixedly connected to the lower surface of the guide block, and a fifth elastic element is fixedly connected between the outer wall of the other end of the sliding rod and the outer wall of the hopper.

[0012] Preferably, the cleaning component includes a hollow column, the inner wall of which is slidably connected to the outer wall of the stirring rod, a second elastic element is fixedly connected between the lower surface of the base plate and the inner wall of the hollow column, and a scraper is fixedly connected to the lower surface of the hollow column.

[0013] Preferably, a protrusion is fixedly connected to the lower surface of the scraper, a locking block is slidably connected to the inner wall of the stirring rod, and a fourth elastic element is fixedly connected between the outer wall of the locking block and the inner wall of the stirring rod.

[0014] Preferably, a support column is slidably connected to the inner wall of the push-pull rod, a third elastic element is fixedly connected between the outer wall of the support column and the inner wall of the push-pull rod, and a limit ring is fixedly connected to the inner wall of the hopper.

[0015] Preferably, the inner wall of the limiting ring is slidably connected to the outer wall of the hollow column, and the inner wall of the hollow column is slidably connected to the outer wall of the push-pull rod.

[0016] Working principle: When repairing cracks, the heating plate heats the mixing tank. Material is then poured in through the feed inlet, and the motor drives the mixing rod to stir the material. The caulking assembly is then lowered, allowing the push-pull plate to slide back and forth. As the push-pull plate slides downwards, it draws caulking material from the mixing tank into the fixed box. As it slides upwards, the caulking material is pushed out through the left-side pipe of the fixed box, ensuring stable material output and preventing waste. The electric push rod pushes and pulls the connecting plate, causing the hollow rod to slide synchronously. The hollow rod connects to the push-pull plate, enabling its reciprocating motion. A limit rod is fixed to the upper surface of the fixed plate, and the hollow rod slides on the outer wall of the limit rod. When the fixed plate is fully retracted, it locks the connecting plate, achieving rapid material discharge.

[0017] This invention provides a crack repair device for highway engineering. It has the following beneficial effects: 1. This invention uses a motor to drive a stirring rod to mix materials, while a heating plate heats the materials to maintain their fluidity. At this time, the electric push rod is activated to push the connecting plate to slide, which in turn drives the hollow rod and the push-pull plate to slide synchronously. The push-pull plate will pull out the sealant and discharge it. The fixed plate, together with the limiting rod, will limit the push-pull plate, which can accurately control the discharge amount of sealant to prevent material waste.

[0018] 2. In this invention, pressing the rotating rod drives the push-pull rod to slide, which in turn drives the right-angle rod to slide and simultaneously drives the inclined block to slide. The inclined block pushes the paving bucket to contact the ground, and the paving bucket controls the discharge of the caulking material into the crack and flattens it by the flattening roller.

[0019] 3. This invention compresses the fifth elastic element while pushing the guide block to slide, and the bonding piece will fit against the crack wall. When the diameter of the crack is adjusted, the fifth elastic element will push the guide block to adjust synchronously, which can make the guide block adjust in real time and achieve the effect of accurately discharging the filling material into different cracks.

[0020] 4. In this invention, the hollow column drives the scraper to contact the crack. At this time, the stirring rod will drive the hollow column to rotate, and the hollow column will drive the protrusion and scraper to clean the crack simultaneously, which can improve the quality of subsequent crack filling.

Detailed Implementation

[0023] The technical solution of the present invention will now be clearly and completely described 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.

[0024] Example 1: Please refer to the appendix. Figure 1 - Appendix Figure 4This invention provides a crack repair device for highway engineering, comprising a base plate 1, a mixing tank 2 fixed to the upper surface of the base plate 1, a heating plate 5 sleeved on the outer wall of the mixing tank 2, and the lower surface of the heating plate 5 fixed to the upper surface of the base plate 1, a motor 3 fixed to the upper surface of the mixing tank 2, a mixing rod 4 fixedly mounted at the output end of the motor 3, a cleaning component 14 mounted on the outer wall of the bottom end of the mixing rod 4, and a fixing box 6 fixed to the inner wall of the base plate 1, wherein the fixing box 6 is connected to the mixing tank 2 and the heating plate 5 via a pipe, and the inner wall of the fixing box 6 is slidable. A push-pull plate 7 is provided, and a first elastic element 13 is fixed between the lower surface of the push-pull plate 7 and the inner wall of the fixed box 6. A hollow rod 8 is fixed on the lower surface of the push-pull plate 7, and the outer wall of the hollow rod 8 slides on the inner wall of the fixed box 6. An electric push rod 9 is fixed on the lower surface of the fixed box 6, and a connecting plate 11 is fixed at the output end of the electric push rod 9. The outer wall of the connecting plate 11 is fixed on the outer wall of the hollow rod 8. A limit rod 10 slides on the inner wall of the hollow rod 8, and a fixed plate 12 is fixed on the lower surface of the limit rod 10. A caulking assembly 15 is provided on the lower surface of the base plate 1.

[0025] Specifically, when repairing cracks, the heating plate 5 is heated to heat the mixing tank 2. At this time, the material is poured in through the feed port on the upper side of the mixing tank 2 near the motor 3. Then, the motor 3 is started to drive the mixing rod 4 to mix the material. After the material is mixed, the bottom plate 1 is pushed to move above the crack. At this time, the crack filling component 15 is lowered to allow the push-pull plate 7 to slide back and forth. When the push-pull plate 7 slides back and forth in conjunction with the first elastic element 13; When the push-pull plate 7 is on the top wall inside the fixed box 6, the push-pull plate 7 will block the pipes on both sides of the upper side of the fixed box 6, so that the push-pull plate 7 can prevent the filling material inside the mixing barrel 2 from being discharged. When the push-pull plate 7 slides back and forth, since the pipes on both sides of the upper side of the fixed box 6 are connected to one-way valves, the push-pull plate 7 will draw the filling material from the inside of the mixing barrel 2 into the inside of the fixed box 6 when it slides down. When the push-pull plate 7 slides up, the filling material will be pushed out by the push-pull plate 7 and discharged into the left pipe of the fixed box 6. This can stably control the discharge for filling while preventing material waste. When the caulking assembly 15 is lowered, it locks the position of the fixing plate 12. At this time, the electric push rod 9 is activated to push and pull the connecting plate 11, causing the connecting plate 11 to drive the hollow rod 8 to slide synchronously. The hollow rod 8 is connected to the push-pull plate 7, which allows the push-pull plate 7 to achieve a reciprocating sliding effect. Since the upper surface of the fixing plate 12 is fixed with the limit rod 10, and the hollow rod 8 slides on the outer wall of the limit rod 10, the running trajectory of the hollow rod 8 can be controlled when adjusting the fixing plate 12. Moreover, when the fixing plate 12 is fully retracted, it can lock the connecting plate 11, which can achieve the effect of quickly controlling whether to discharge material.

[0026] Example 2: Please refer to the appendix. Figure 2 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 and attached Figure 8 The caulking assembly 15 includes a hopper 1510, the upper surface of which is slidably connected to the lower surface of the base plate 1. The outer wall of the hopper 1510 is fixedly connected to the outer wall of the fixing plate 12. A support block 1501 is fixedly connected to the upper surface of the base plate 1. A handle 1502 is fixedly connected to the inner wall of the support block 1501. A telescopic block 1503 is slidably connected to the lower outer wall of the base plate 1. A flattening roller 1504 is rotatably connected to the inner wall of the telescopic block 1503. A rotating rod 1505 is slidably connected to the inner wall of the support block 1501. An elastic telescopic rod 1506 is rotatably connected to the outer wall of the rotating rod 1505. The bottom outer wall of the elastic telescopic rod 1506 is rotatably connected to the inner wall of the base plate 1. A push-pull rod 1507 is rotatably connected to the outer wall of the rotating rod 1505. The outer wall of the push-pull rod 1507 is slidably connected to... A right-angle rod 1508 is fixedly connected to the lower surface of the push-pull rod 1507 on the inner wall of the base plate 1. The outer wall of the right-angle rod 1508 is slidably connected to the inner wall of the base plate 1 and the inner wall of the hopper 1510. An inclined block 1509 is fixedly connected to the outer wall of the right-angle rod 1508. The inclined outer wall of the inclined block 1509 is slidably connected to the inner wall of the hopper 1510. A sliding rod 1512 is slidably connected to the inner wall of the hopper 1510. A guide block 1511 is fixedly connected to the outer wall of one end of the sliding rod 1512. The outer wall of the guide block 1511 is slidably connected to the inner wall of the hopper 1510. A bonding piece 1514 is fixedly connected to the lower surface of the guide block 1511. A fifth elastic element 1513 is fixedly connected between the outer wall of the other end of the sliding rod 1512 and the outer wall of the hopper 1510.

[0027] Specifically, the construction worker pushes the handle 1502 to move the base plate 1. At this time, the flattening roller 1504 will drive the telescopic block 1503 to slide on the outer wall of the base plate 1, so that the flattening roller 1504 can fit with the ground, which can facilitate the flattening of the repair material. When it is necessary to fill the gap, press the rotating rod 1505. While the rotating rod 1505 slides on the inner wall of the support block 1501, it will squeeze the elastic telescopic rod 1506. After the rotating rod 1505 is fully pressed, the elastic telescopic rod 1506 will push the rotating rod 1505 and the push-pull rod 1507 to slide synchronously. Moreover, after pulling the rotating rod 1505, the elastic telescopic rod 1506 will push the rotating rod 1505 to reset. Sliding the push-pull rod 1507 will push the right-angle rod 1508 to slide on the inner wall of the base plate 1. At this time, the right-angle rod 1508 will pull the tilting block 1509 to slide synchronously. Since the tilting block 1509 is an inclined surface, the hopper 1510 slides down and contacts the ground. The hopper 1510 will also drive the fixing plate 12 to slide synchronously. The top of the tilting block 1509 is designed with a right angle, which allows the tilting block 1509 to lock the hopper 1510 to prevent the hopper 1510 from falling off. The right-angle rod 1508 will also lock the cleaning component 14. When the hopper 1510 contacts the ground, the sliding rod 1512 slides against the inner wall of the hopper 1510, compressing the fifth elastic element 1513. This causes the guide block 1511 to drive the bonding piece 1514 to contact the crack. At this time, when the base plate 1 moves, the bonding piece 1514 will slide along the crack wall, and the guide block 1511 will adjust in conjunction with the fifth elastic element 1513 and the bonding piece 1514, allowing the guide block 1511 to adjust in real time according to the diameter of the crack. At this time, the repair material is discharged to the upper surface of the hopper 1510 through the lower outlet of the fixing box 6. The guide block 1511 has a figure-eight design, which allows the repair material to be adjusted synchronously according to the sliding of the guide block 1511, enabling the repair material to be accurately put into the crack for repair.

[0028] Please see the appendix Figure 7 - Appendix Figure 9 The cleaning component 14 includes a hollow column 1401, the inner wall of which is slidably connected to the outer wall of the stirring rod 4. A second elastic element 1402 is fixedly connected between the lower surface of the base plate 1 and the inner wall of the hollow column 1401. A scraper 1405 is fixedly connected to the lower surface of the hollow column 1401, and a protrusion 1404 is fixedly connected to the lower surface of the scraper 1405. A locking block 1408 is slidably connected to the inner wall of the stirring rod 4, and the outer wall of the locking block 1408 is connected to the stirring rod 4. A fourth elastic element 1409 is fixedly connected between the inner walls of the push-pull rod 1507 and the inner wall of the push-pull rod 1507. A support column 1407 is slidably connected to the inner wall of the support column 1407 and the inner wall of the push-pull rod 1507. A third elastic element 1406 is fixedly connected between the outer wall of the support column 1407 and the inner wall of the push-pull rod 1507. A limit ring 1403 is fixedly connected to the inner wall of the hopper 1510. The inner wall of the limit ring 1403 is slidably connected to the outer wall of the hollow column 1401. The inner wall of the hollow column 1401 is slidably connected to the outer wall of the push-pull rod 1507.

[0029] Specifically, when the hopper 1510 slides into contact with the ground, the hopper 1510 will cause the limiting ring 1403 to slide on the outer wall of the hollow column 1401. Since the right-angle rod 1508 slides away from the hollow column 1401, the third elastic element 1406 installed on the inner wall of the right-angle rod 1508 will push the support column 1407 to lock the hollow column 1401. This allows the hollow column 1401 to limit the limiting ring 1403 while preventing the hollow column 1401 from falling off. When it is necessary to clean impurities from the cracks, the right-angle rod 1508 disengages the support column 1407 from the hollow column 1401, causing the second elastic element 1402 to push the hollow column 1401 to slide, and the locking block 1408 and the fourth elastic element 1409 to lock the hollow column 1401. This achieves the effect of quickly connecting the hollow column 1401 with the stirring rod 4, while the limiting ring 1403 limits the hollow column 1401. At this time, the stirring rod 4 rotates, which drives the hollow column 1401 to rotate synchronously. The hollow column 1401 then drives the scraper 1405 to rotate, causing the scraper 1405 to drive the convex... While the lifting block 1404 cleans the crack, the scraper block 1405 drives the ring-shaped scraper blades to rotate synchronously, achieving the effect of cleaning the crack wall. Due to the inclined design of the scraper blades, the scraped impurities are discharged into the interior of the hopper 1510 through the scraper block 1405 and the scraper blades. The bottom wall of the hopper 1510 is also inclined, so the impurities are discharged to both sides of the crack and do not come into contact with the flattening roller 1504, which can improve the repair quality. When the right-angle rod 1508 retracts, the hopper 1510 will drive the hollow column 1401 to retract synchronously and lock, achieving the effect of rapid reset.

[0030] The workflow involves controlling the heating plate 5 installed on the mixing tank 2 to heat up to the preset temperature. After the temperature of the heating plate 5 stabilizes, the sealant is poured into the mixing tank 2 through the feed inlet. At this time, the motor 3 is started, and the motor 3 drives the stirring rod 4 to rotate, which stirs and mixes the sealant in the mixing tank 2. After the materials are mixed, the construction workers push the base plate 1 to move it above the crack to be repaired by using the handle 1502, and press the rotating rod 1505 to slide on the inner wall of the support block 1501. At the same time, the elastic telescopic rod 1506 is squeezed to drive the rotating rod 1505 and the push-pull rod 1507 to slide synchronously. The push-pull rod 1507 drives the right-angle rod 1508 to slide on the inner wall of the base plate 1, so that the paving bucket 1510 contacts the ground, and the guide block 1511 will drive the bonding piece 1514 to contact the crack wall. When the electric push rod 9 is activated, the connecting plate 11 is pushed and pulled by the electric push rod 9. The connecting plate 11 drives the hollow rod 8 to slide along the outer wall of the limiting rod 10 and fix the limiting rod 10 to the upper surface of the fixed plate 12. This allows the push-pull plate 7 to achieve the effect of stably conveying the joint filling material. After the joint filling material falls into the hopper 1510, the figure-eight guide block 1511 will move along the crack, which can achieve the effect of accurately conveying the joint filling material. The flattening roller 1504 can flatten the joint filling material. The stirring rod 4 drives the hollow column 1401 to rotate, which in turn drives the scraper 1405 and the protruding block 1404 to rotate, thoroughly cleaning the impurities on the inner wall of the crack and ensuring the quality of subsequent repairs.
