Description

Technical Field

[0001] This utility model relates to the field of concrete curing equipment, and in particular to a curing device for preventing concrete cracks. Background Technology

[0002] Concrete curing involves artificially creating certain humidity and temperature conditions to allow freshly poured concrete to harden and increase its strength normally or at an accelerated pace. The gradual hardening and strength increase of concrete is a result of cement hydration, which requires specific temperature and humidity conditions.

[0003] After prolonged use, concrete pavements often develop cracks, necessitating maintenance and repair. Current methods typically involve manual filling and repair of these cracks, which is cumbersome and inconvenient. Existing technology CN216764735U relates to a maintenance device for preventing concrete cracking. The device includes a base, a motor mounted on its side, a lead screw connected to the motor's output, a movable seat threadedly connected to the center of the base, and a spraying mechanism for repairing concrete cracks at the top of the base. This device, comprising a motor, lead screw, spray plate, nozzle, movable seat, repair agent pump, and repair tank, enables spraying of concrete cracks. It allows for back-and-forth spraying, improving spraying effectiveness and work efficiency. The inclusion of casters, swivel casters, and a handle facilitates movement of the base in any direction. The use of lugs, rotating parts, pointers, and indicator needles facilitates alignment of the concrete cracks, further enhancing the spraying effect.

[0004] In the aforementioned document, cracks are repaired by spraying. However, since cracks vary in size, even though the nozzle is aligned with the crack, the repair agent often sprays outside the crack. Existing technology lacks the process of smoothing the road surface after repair. After grouting, manual scraping is required to smooth out the excess sealant, which is not only time-consuming but also wastes sealant and increases the workload of workers. To address these issues, a solution is proposed below. Utility Model Content

[0005] The purpose of this invention is to provide a curing device to prevent concrete cracks, thereby solving the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A curing device for preventing concrete cracking includes a base and a storage bin. The storage bin is mounted on top of the base, and a feed hopper is installed on the top of the storage bin. A discharge port is opened on the bottom side wall of the storage bin, and a discharge pipe is installed on the discharge port. A pump is mounted on the base, and one end of the discharge pipe is fixedly connected to the feed end of the pump. A connecting pipe is slidably arranged on the base, and a discharge pipe is installed on the discharge end of the pump. One end of the discharge pipe is fixedly connected to the top of the connecting pipe. The base also has a drive assembly for moving the connecting pipe. The bottom of the connecting pipe penetrates the base and is equipped with a spray head. A second connecting pipe is slidably arranged outside the first connecting pipe, and the bottom of the second connecting pipe also penetrates the base. Multiple scrapers are installed on the bottom side wall of the second connecting pipe. The base has a rotating assembly for rotating the second connecting pipe.

[0008] Preferably, the drive assembly includes an upright plate, a support plate, and a sliding plate. The upright plate is mounted on the base, and the support plate is mounted on the top of the upright plate. An electric telescopic rod is mounted on the top of the support plate. The movable end of the electric telescopic rod passes through the support plate and is fixedly connected to the top of the sliding plate. A connecting pipe is fixed to the side wall of the sliding plate. A sliding rod is also installed between the support plate and the base. A through hole is provided on the sliding plate. The sliding plate is slidably mounted on the sliding rod through the through hole, and the sliding plate achieves limited movement through the sliding rod.

[0009] Preferably, the rotating assembly includes a first pulley, a second pulley, a first belt, and a first drive motor. The first drive motor is mounted on a base, the first pulley is fixed on the output shaft of the first drive motor, a support ring is mounted on the base, the support ring is disposed outside the second connecting pipe, the second pulley is rotatably mounted on the support ring, multiple sliding grooves are formed on the outer wall of the second connecting pipe, multiple first sliders are fixed on the inner wall of the second pulley, the first sliders are slidably disposed in the sliding grooves, the second pulley drives the second connecting pipe to rotate through the first sliders, and the first pulley and the second pulley are connected by the first belt.

[0010] Preferably, the inner wall of the second connecting pipe is provided with an annular groove, and a plurality of second locking blocks are fixed on the outer wall of the first connecting pipe. The bottom of the second locking block is provided with a ball bearing. The second locking block is adapted to the annular groove, and the second connecting pipe is supported by the second locking block.

[0011] Preferably, the scraper includes a support strip and a rubber scraper. One end of the support strip is fixed to the side wall of the second connecting pipe. The support strip has a trapezoidal structure that is smaller at the top and larger at the bottom. The rubber scraper is slidably disposed on the support strip and is engaged with the support strip.

[0012] Preferably, the storage bin has an internal cavity, an electric heating plate is installed inside the cavity, and an observation window is provided vertically on the storage bin.

[0013] Beneficial effects: When repairing cracks, the drive assembly can be activated first, which raises and lowers the sliding plate. The sliding plate then raises and lowers the first connecting pipe, which in turn moves the bottom spray head deeper into the crack, making it easier to repair. During the raising and lowering process, the first connecting pipe also raises and lowers the second connecting pipe, which contacts the ground first. As the first connecting pipe continues to move, the second locking block on its outer wall contacts the bottom of the annular groove, pressing it down and allowing the scraper to contact the ground for subsequent leveling. When supplying material to repair cracks, the rotating assembly can rotate the second connecting pipe, which in turn rotates the scraper, allowing it to level the repair slurry. No further manual operation is required, reducing labor input and improving construction efficiency. Attached Figure Description

Detailed Implementation

[0020] See Figures 1 to 5 As shown, a curing device for preventing concrete cracks includes a base 1 and a storage box 2. The storage box 2 is installed on the top of the base 1, and a feed hopper 3 is installed on the top of the storage box 2. When it is necessary to cure and repair cracks in the concrete pavement, the repair agent or filler to be used for repair can be poured into the storage box 2 through the feed hopper 3. The storage box 2 stores the raw materials for subsequent use. The storage box 2 has a cavity inside, and an electric heating plate is installed in the cavity. By setting the electric heating plate inside the cavity, the storage box 2 can be heated by activating the electric heating plate, which can heat the raw materials and prevent them from solidifying. The storage box 2 also has a vertical observation window, which allows the use of raw materials in the storage box 2 to be observed.

[0021] A discharge port is provided on the bottom side wall of the storage box 2, and a discharge pipe 4 is installed on the discharge port. A pump 5 is installed on the base 1. One end of the discharge pipe 4 is fixedly connected to the inlet end of the pump 5. A connecting pipe 6 is slidably arranged on the base 1. A discharge pipe 7 is installed on the discharge end of the pump 5. One end of the discharge pipe 7 is fixedly connected to the top of the connecting pipe 6. The base 1 is also provided with a drive assembly 8 for moving the connecting pipe 6. When it is necessary to repair the crack, the drive assembly 8 can be started first. The drive assembly 8 drives the connecting pipe 6 to rise and fall. The bottom of the connecting pipe 6 passes through the base 1 and is equipped with a spray head 9. The connecting pipe 6 will drive the spray head 9 at the bottom to rise and fall, so that the spray head 9 can be located in the crack to repair the crack.

[0022] The drive assembly 8 includes a vertical plate 81, a support plate 82, and a sliding plate 83. The vertical plate 81 is mounted on the base 1, and the support plate 82 is mounted on the top of the vertical plate 81. An electric telescopic rod 84 is mounted on the top of the support plate 82. The movable end of the electric telescopic rod 84 passes through the support plate 82 and is fixedly connected to the top of the sliding plate 83. A connecting pipe 6 is fixed to the side wall of the sliding plate 83. A sliding rod 85 is also installed between the support plate 82 and the base 1. A through hole is provided on the sliding plate 83. The sliding plate 83 is slidably mounted on the sliding rod 85 through the through hole. When it is necessary to push the connecting pipe 6 to move up or down, the electric telescopic rod 84 can be activated first. The movable end of the electric telescopic rod 84 pushes the sliding plate 83 to slide on the sliding rod 85. The sliding plate 83 achieves limited movement through the sliding rod 85. During the movement, the sliding plate 83 will drive the connecting pipe 6 to move, and the connecting pipe 6 can drive the bottom spray head 9 to move up or down to the specified height.

[0023] Once the connecting pipe 6 and the spray head 9 have moved to the designated height, the material pump 5 will start. The material pump 5 will extract the raw material from the storage tank 2 through the discharge pipe 4 and discharge it into the discharge pipe 7. The discharge pipe 7 will transport the raw material to the connecting pipe 6. Finally, the raw material will enter the spray head 9 through the connecting pipe 6 and be sprayed out to fill the crack. The discharge pipe 7 adopts a flexible hose structure to facilitate the movement of the discharge pipe 7 and the connecting pipe together.

[0024] A second connecting pipe 10 is slidably mounted on the outside of the first connecting pipe 6. The bottom of the second connecting pipe 10 also penetrates the base 1. Multiple scrapers 11 are installed on the bottom side wall of the second connecting pipe 10. The inner wall of the second connecting pipe 10 is also provided with an annular groove 13. Multiple locking blocks 14 are fixed on the outer wall of the first connecting pipe 6. The bottom of the locking blocks 14 is provided with rotatable ball bearings. The locking blocks 14 are adapted to the annular groove 13. The second connecting pipe 10 is supported by the locking blocks 14. In the initial state, the first connecting pipe 6 and the spray head 9 are both located inside the second connecting pipe 10. When the first connecting pipe 6 is raised and lowered, the second connecting pipe 10 will contact the ground first. As the first connecting pipe 6 continues to move, the locking blocks 14 on the outer wall of the first connecting pipe 6 will contact the bottom of the annular groove 13. The locking blocks 14 are used to press the second connecting pipe 10 together, thereby making the scraper 11 contact the ground, which is convenient for subsequent leveling construction.

[0025] The base 1 is equipped with a rotating component 12 for driving the second connecting pipe 10 to rotate. When supplying material to repair cracks, the rotating component 12 can drive the second connecting pipe 10 to rotate. The rotation of the second connecting pipe 10 will drive the scraper 11 to rotate, so that the scraper 11 can scrape the repair slurry flat.

[0026] The rotating assembly 12 includes a first pulley 121, a second pulley 122, a first belt 123, and a first drive motor 124. The first drive motor 124 is mounted on the base 1. The first pulley 121 is fixed on the output shaft of the first drive motor 124. A support ring 125 is mounted on the base 1, and the support ring 125 is located outside the second connecting pipe 10. The second pulley 122 is rotatably mounted on the support ring 125. Multiple sliding grooves 126 are formed on the outer wall of the second connecting pipe 10. Multiple sliders 127 are fixed on the inner wall of the second pulley 122, and the sliders 127 are slidably mounted in the sliding grooves 126. The second pulley 122 drives the second connecting pipe 10 to rotate through the sliders 127. The first pulley 121 and the second pulley 122 are connected by the first belt 123. 3. To achieve the connection, when it is necessary to drive the second connecting pipe 10 to rotate, the first drive motor 124 can be started first. The first drive motor 124 can drive the first pulley 121 to rotate, which in turn drives the first belt 123 to transmit power. The first belt 123 can drive the second pulley 122 to rotate. The second pulley 122 is supported by the support ring 125. When the second connecting pipe 10 slides and rises through the first connecting pipe 6, the slider 127 of the second pulley 122 will slide in the groove 126. When the second pulley 122 rotates, it will drive the slider 127 to rotate in the groove 126. The slider 127 can push the second connecting pipe 10 to rotate, which in turn drives the scraper 11 to rotate.

[0027] The scraper 11 includes a support bar 111 and a rubber scraper 112. One end of the support bar 111 is fixed to the side wall of the connecting pipe 10. The support bar 111 adopts a trapezoidal structure with a smaller top and a larger bottom. The rubber scraper 112 is slidably mounted on the support bar 111. The rubber scraper 112 and the support bar 111 are engaged. By dividing the scraper 11 into the support bar 111 and the rubber scraper 112, the rubber scraper 112 is located at the bottom of the support bar 111. Since the rubber scraper 112 will contact and rotate with the ground during the leveling process, the rubber scraper 112 will wear after long-term use. Therefore, the above design allows the rubber scraper 112 to be disassembled and replaced, which facilitates better leveling.

[0028] The base 1 is also equipped with a battery and a protective box for protecting the battery. All drive components on the base 1 are powered by the battery.
