Description

Technical Field

[0001] This application relates to the technical field of crack repair accessories, and in particular to a concrete crack repair accessory. Background Technology

[0002] Concrete cracks are physical structural changes caused by internal and external factors. Cracks are a major cause of reduced load-bearing capacity, durability, and waterproofing of concrete structures. If the cracks are not particularly severe and only cause water seepage, a caulking method can be used. First, chisel a V-shaped groove along the crack, remove debris, and rinse with water. Next, apply a layer of anti-water-repellent solution to the crack surface. After it dries completely, smooth the surface with a scraper, then spray with water to keep it moist. Next, mix polymer-modified cement mortar according to the specified ratio, embed it into the crack with a scraper, and smooth it out. After it hardens, water it for curing. If the cracking is more severe, chemical grouting is required. Because these cracks are usually through-cracks, a groove must first be cut, and the cement mortar filled into the crack. Then clean it with a wire brush, rinse with water, spray with polymer-modified cement mortar, and after curing, perform chemical grouting with a water-soluble polyurethane solution.

[0003] A search revealed Chinese Patent Publication No. CN109594788A, which discloses a concrete crack repair tool, comprising a cylinder, a nozzle, a pusher, a bolt pusher, and a nut cap. The nozzle is detachably connected to the cylinder, and a nut cap with a screw hole is located at the rear end of the cylinder. The pusher is housed within the cylinder, and the bolt pusher passes through the screw hole in the nut cap and is fixedly connected to the pusher. This design utilizes the rotational force of the bolt pusher to ensure more even and less strenuous injection of the repair agent. Furthermore, a larger amount of grout can be loaded into the cylinder at once, making repair more convenient and continuous, and ensuring a tighter and more solid bond between the injected grout and the crack pores. This repair tool is easy to operate, clean, use, and has low manufacturing costs, making it highly practical.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Currently, the common method for repairing concrete cracks involves workers pushing adhesive material from inside the cylinder into the crack for repair. However, the size and width of concrete cracks vary depending on the environment, requiring workers to replace the nozzle and repeatedly drive the bolt pusher to push the adhesive material into the crack. This increases the labor intensity of workers and reduces work efficiency. Summary of the Invention

[0018] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0019] This application discloses an auxiliary tool for repairing concrete cracks. For example... Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the device includes a housing 1, with a feed hopper 2 rotatably mounted on the upper end of the housing 1. A discharge pipe 3 is provided on the feed hopper 2. A turntable 4 is rotatably mounted on the housing 1. A circulation mechanism 5 is provided between the turntable 4 and the feed hopper 2. The circulation mechanism 5 includes a slide groove 501, which is located on the turntable 4. A fixing block 502 is slidably mounted within the slide groove 501. A fastening bolt is provided between the fixing block 502 and the turntable 4. By rotating the fastening bolt, the restriction between the fixing block 502 and the turntable 4 is released, facilitating the adjustment of the position of the fixing block 502 within the slide groove 501, and allowing the fixing block 502 to be adjusted to a preset position. After the fixing block 502 is adjusted to the preset position, the fastening bolt is rotated in the reverse direction, thereby fixing the position of the fixing block 502 and achieving the effect of arbitrarily adjusting the position of the fixing block 502. The fixing block 502 is provided with a mounting plate 503, and a universal ball 504 is provided between the fixing block 502 and the mounting plate 503. The fixing block 502 and the mounting plate 503 are connected by fixing bolts. By removing the fixing bolts, the fixing block 502 is separated from the mounting plate 503, releasing the restriction on the universal ball 504 and making it easy to remove the universal ball 504. A connecting rod 505 is fixedly installed on the universal ball 504.

[0020] Please see Figure 1 , Figure 6 , Figure 7A connecting plate 506 is fixedly installed at the end of the connecting rod 505 away from the universal ball 504. The lower end of the feed hopper 2 is rotatably connected to the inner wall of the box 1 via a rotating shaft 509. A fixing rod 508 is fixedly installed on the rotating shaft 509, and a sleeve 507 is rotatably installed on the fixing rod 508. The sleeve 507 is fixedly connected to the connecting plate 506. A motor 510 is provided at the power end of the turntable 4. The motor 510 drives the turntable 4 to rotate, achieving uniform rotation of the turntable 4. The turntable 4 drives the universal ball 504 to rotate accordingly. The connecting rod 505 and the connecting plate 506 move, and the connecting plate 506 drives the rotating shaft 509 to rotate through the sleeve 507. While the rotating shaft 509 rotates, it restricts the movement of the connecting plate 506, so that the universal ball 504 rotates. The motor 510 is fixedly installed on the housing 1. A protective shell 10 is installed on the housing 1. The protective shell 10 is located at one end of the motor 510. The protective shell 10 is fixedly connected to the housing 1 by fixing bolts. By removing the fixing bolts, the protective shell 10 can be removed, which facilitates the replacement and maintenance of the motor 510 and improves the service life of the device.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A rechargeable lithium battery 11 is installed on the housing 1 and is snapped into the housing 1. Multiple rechargeable lithium batteries 11 can be used interchangeably, enabling the device to be used for a long time, ensuring stable working efficiency, and avoiding the need for charging during operation, thus reducing the working time. A storage cylinder 6 is installed at the upper end of the feeding hopper 2. The storage cylinder 6 is connected to the housing 1 by a fixing mechanism 7. The fixing mechanism 7 includes two support plates 701. One end of the two support plates 701 is fixedly installed on the upper end of the housing 1, and the other end is connected by a fixing plate 702. The fixing plate 702 fixes the upper end of the two support plates 701, thereby ensuring the stability of the upper end. A limit ring 1 703 is set between the two support plates 701, and a limit ring 2 707 is set between the feeding hopper 2 and the limit ring 1 703. The limit ring 2 707 restricts the bottom of the storage cylinder 6, thereby ensuring the stability of the storage cylinder 6 and improving the stability of the device during use.

[0022] Please see Figure 2 , Figure 4Limiting ring 2 707 is fixedly connected to support plate 701. The inner wall of limiting ring 2 707 is slidably connected to storage cylinder 6. Limiting plate 704 is provided between limiting ring 1 703 and support plate 701. Limiting plate 704 restricts the movement of limiting ring 1 703, so that limiting ring 1 703 can only move in a specified direction, ensuring the stability of limiting ring 1 703. Limiting plate 704 is fixedly connected to support plate 701. Limiting groove 705 is provided on limiting ring 1 703 at the corresponding position of limiting plate 704. Limiting ring 1 703 is slidably connected to limiting plate 704. By pushing limiting ring 2 707 to move, the limiting ring... The second 707 pushes the upper part of the storage cylinder 6, thereby releasing the restriction on the storage cylinder 6. At this time, the storage cylinder 6 can be removed and replaced. The new storage cylinder 6 can be placed in the installation position, and the second 707 is driven to move in the opposite direction, so that the second 707 is fitted on the upper part of the storage cylinder 6, restricting and fixing the upper part of the storage cylinder 6, ensuring the stability of the device, and making the working process smoother. The lower end of the limiting plate 704 is provided with a baffle 706, which is fixedly connected to the support plate 701. The baffle 706 restricts the position of the limiting plate 704 and prevents the limiting plate 704 from falling and affecting the stability of the upper part of the storage cylinder 6.

[0023] Please see Figure 1 , Figure 8 The upper end of the fixed mechanism 7 is provided with a pushing mechanism 8, which includes a multi-stage electric telescopic rod 801. The multi-stage electric telescopic rod 801 is fixedly installed on the fixed plate 702 by fixing bolts. By removing the fixing bolts, the multi-stage electric telescopic rod 801 can be removed from the fixed plate 702, which facilitates the maintenance and replacement of the multi-stage electric telescopic rod 801 by the staff, thereby ensuring the normal operation of the device and improving its service life. The output end of the multi-stage electric telescopic rod 801 is fixedly installed with a fixed column 802. During operation, the multi-stage electric telescopic rod 801 drives the fixed column 802 to rotate, thereby moving the fixed column 802 along the specified direction and adjusting the fixed column 802 to the specified position.

[0024] Please see Figure 8A connecting mechanism 9 is provided between the pushing mechanism 8 and the storage cylinder 6. The connecting mechanism 9 includes a connecting column 901. One end of the connecting column 901 is mounted on and threadedly connected to the fixed column 802, and the other end is fixedly mounted with a connecting shaft 902. The direction of the connecting column 901 is restricted by the fixed column 802. A push plate 903 is slidably installed inside the storage cylinder 6. The push plate 903 is provided with a threaded groove 904. The connecting shaft 902 is threadedly connected to the threaded groove 904. When the storage cylinder 6 is dismantled, the connecting column 901 is driven during operation. When rotated, the connecting column 901 moves on the fixed column 802, and at the same time, the fixed column 802 drives the connecting shaft 902 to rotate accordingly. The connecting shaft 902 moves from the threaded groove 904, thereby releasing the fixation of the push plate 903 and releasing the restriction of the storage cylinder 6. During installation, by driving the connecting column 901 to rotate in the opposite direction, the connecting column 901 moves downward along the fixed column 802. At the same time, the connecting column 901 drives the connecting shaft 902 into the threaded groove 904 and connects with the threaded groove 904, thereby connecting the push plate 903 to the multi-stage electric telescopic rod 801.

[0025] The implementation principle of a concrete crack repair auxiliary tool according to this application embodiment is as follows: During the working process, the adhesive material is first poured into the storage cylinder 6, and then the limiting ring 703 is driven to move so that the length between the limiting ring 703 and the limiting ring 707 is greater than that of the storage cylinder 6; then, one end of the prepared storage cylinder 6 is passed through the limiting ring 707 and inserted into the feeding hopper 2, and the limiting ring 703 is lowered and placed on the storage cylinder 6. The limiting rings 703 and 707 restrict both ends of the storage cylinder 6 to ensure the stability of the storage cylinder 6. Then, the connecting column 901 is driven to rotate, and the connecting column 901 moves along the fixed... The column 802 moves, and the fixed column 802 drives the connecting shaft 902 to move into the threaded groove 904, connecting the connecting shaft 902 with the threaded groove 904. This connects the multi-stage electric telescopic rod 801 to the push plate 903, opening one side of the housing 1. Then, the fastening bolts rotate, releasing the fixing block 502 from the turntable 4. The fixed block 502 is then moved within the slide 501 and adjusted to a preset position, thus controlling the rotation of the discharge pipe 3. The position of the fixed block 502 within the slide 501 can be adjusted according to actual needs to control the rotation angle, facilitating the handling of mixed materials of different sizes. The concrete cracks are processed, increasing the applicability of the device. Then, the carrying case 1 aligns the discharge pipe 3 with the concrete crack and drives the motor 510. The motor 510 drives the turntable 4 to rotate, which in turn drives the fixed block 502 and mounting plate 503 to rotate, simultaneously driving the universal ball 504 to rotate. The universal ball 504 drives the connecting rod 505 and connecting plate 506 to rotate circumferentially. Simultaneously, the rotation of the connecting plate 506 drives the sleeve 507 to drive the rotating shaft 509 to rotate, achieving a cyclical oscillation of the rotating shaft 509. The cyclical oscillation of the rotating shaft 509 drives the feed hopper 2 to rotate accordingly. At the same time, the multi-stage electric telescopic rod 801 drives the push plate 903 in the storage cylinder. The material cylinder 6 moves inward, pushing the adhesive material in the storage cylinder 6 into the hopper 2 and flowing out from the discharge pipe 3. At the same time, the hopper 2 drives the discharge pipe 3 to rotate and fill the concrete cracks. When the storage cylinder 6 on the device is used up, the connecting column 901 is driven to rotate. The connecting column 901 rotates upward along the fixed column 802. While the connecting column 901 rotates, it drives the connecting shaft 902 to rotate as well, and rotates the connecting shaft 902 out of the threaded groove 904, thereby releasing the fixation between the connecting column 901 and the push plate 903. Then, the limit ring 703 is driven to move upward, releasing the restriction on the upper part of the storage cylinder 6. Then, the storage cylinder 6 can be directly pulled out for replacement.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
