Description

Technical Field

[0001] This utility model relates to the technical field of wall repair equipment, specifically an auxiliary device for repairing cracks in building structures. Background Technology

[0002] In the field of building maintenance and repair, crack repair during high-altitude operations has always been a challenging task. As building height increases, timely and effective crack repair becomes increasingly difficult. Especially in high-rise buildings or hard-to-reach areas, traditional crack repair methods often face numerous limitations.

[0003] Traditional high-altitude crack repair work typically relies on manual operation, which is not only inefficient but also poses significant safety hazards. The limited amount of repair material available at heights often fails to meet the needs of repairing large-area cracks, forcing work to be interrupted while waiting for replenishment. This necessitates the use of lifting mechanisms to move the repair materials, further reducing efficiency. Therefore, we propose an auxiliary device for building crack repair. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] An auxiliary device for repairing cracks in a building includes a mounting base 1. A U-shaped frame 2 is mounted on the top of the mounting base 1, with an opening directly below the U-shaped frame 2. Two hollow connecting seats 3 are symmetrically fixed on the top of the mounting base 1. A storage bin 4 is detachably installed between the two connecting seats 3. A winding roller 20 is rotatably mounted inside the U-shaped frame 2. A lifting rope 21 is mounted on the winding roller 20, and two connecting rings 210 are mounted on the movable end of the lifting rope 21. Two lifting rings 44 are symmetrically welded to the top of the storage bin 4, which are respectively connected to the two connecting rings 210. A drive motor 22 with an output shaft coaxially fixed to the winding roller 20 is mounted on the U-shaped frame 2. An air pump 5 is fixedly mounted on the top of the U-shaped frame 2. A first air supply pipe 51 is installed at the air outlet of the air pump 5. The first air supply pipe 51 communicates with the interior of one of the connecting seats 3. A discharge pipe 31 is installed on the other connecting seat 3, and a filler pipe 61 is installed on the discharge pipe 31. The design of the U-shaped frame 2 and the winding roller 20 allows for easy lifting and lowering of the storage bin 4 using the lifting rope 21 and lifting ring 44, facilitating the transport of repair materials to the crack. Simultaneously, by inflating the storage bin 4 with the air pump 5 and the first air supply pipe 51, the repair material is propelled out through the discharge pipe 31, thus repairing the crack. The entire device has a simple structure and is easy to operate, significantly improving the efficiency and quality of building crack repair.

[0027] In a preferred embodiment, the mounting base 1 has a coaxially integrally formed mounting tube 32 near the storage hopper 4. A threaded sleeve 33 is provided on the outer side of the mounting tube 32, and the inner ring wall of the threaded sleeve 33 is threadedly connected to the outer ring wall of the storage hopper 4. The design of the mounting tube 32 and the threaded sleeve 33 enables a detachable connection between the storage hopper 4 and the mounting base 1, facilitating the replacement and cleaning of the storage hopper 4. Simultaneously, the threaded connection ensures the stability and reliability of the connection.

[0028] In this preferred embodiment, the length of the storage bin 4 is equal to the distance between the two mounting pipes 32, and when the threaded sleeve 33 is tightened on the outer ring wall of the storage bin 4, the storage bin 4 and the two mounting pipes 32 are tightly fitted. This further ensures the stability and sealing of the storage bin 4 during installation and prevents leakage of repair materials.

[0029] In a preferred embodiment, a piston 45 that can move left and right is slidably installed inside the storage bin 4. The storage bin 4 has a feeding / discharging port 40 near the discharge pipe 31 and an air inlet 41 near the first air supply pipe 51. The piston 45, which can move left and right inside the storage bin 4, combined with the design of the feeding / discharging port 40 and the air inlet 41, enables convenient feeding and discharging of repair materials, improving the flexibility of the equipment.

[0030] In a preferred embodiment, a first sealing cap 42 and a second sealing cap 43 are threaded onto the discharge port 40 and the air inlet 41, respectively, and each sealing cap has a strip-shaped screw head integrally formed on its outer wall. This effectively prevents leakage of repair materials during transportation or storage, and the screw head design also facilitates the opening and closing of the sealing caps.

[0031] In a preferred embodiment, a limiting block 450 is fixedly connected to both the top and bottom of the piston 45, and a strip groove 46 is provided at both the top and bottom of the inner ring wall of the storage bin 4. The two limiting blocks 450 are slidably connected to the two strip grooves 46 respectively. This limits the range of movement of the piston 45, prevents the piston 45 from derailing or being damaged during movement, and improves the stability and durability of the equipment.

[0032] In a preferred embodiment, the air pump 5 has an electromagnetic three-way valve 50 installed at its outlet. One outlet of the electromagnetic three-way valve 50 is connected to the first air supply pipe 51, and the other outlet is connected to a second air supply pipe 52. An air blowing pipe 63 is installed at the end of the second air supply pipe 52 away from the air pump 5. This allows the air pump 5 to both inflate the storage hopper 4 to push repair material and blow air into the cracks through the second air supply pipe 52 to clean the cracks.

[0033] In a preferred embodiment, a separately provided mounting plate 6 is also included. A first external delivery pipe 60, communicating with the discharge pipe 31, is mounted on the mounting plate 6. A packing pipe 61 is mounted on the first external delivery pipe 60. A second external delivery pipe 62, communicating with the second air delivery pipe 52, is also mounted on the mounting plate 6. An air blowing pipe 63 is connected to the second external delivery pipe 62. The mounting plate 6 integrates the discharge pipe 31 and the second air delivery pipe 52, increasing convenience during use and effectively preventing pipe tangling.

[0034] In this preferred embodiment, a fixing hole is provided at each of the four corners of the mounting base 1, and the length of the opening is greater than the length of the storage bin 4. The fixing holes at the four corners of the mounting base 1 facilitate the fixing and installation of the equipment, while the length of the opening being greater than the length of the storage bin 4 ensures that the storage bin 4 is not restricted by the opening during lifting, thereby improving the practicality and stability of the equipment.

[0035] In this preferred embodiment, the length of the mounting tube 32 is greater than the length of the threaded sleeve 33, and the threaded sleeve 33 never disengages from the mounting tube 32 during use. This ensures that the mounting tube 32 or the threaded sleeve 33 itself will not be damaged due to excessive force when tightening or loosening the threaded sleeve 33, thus improving the durability and safety of the equipment.

[0036] When using the auxiliary device for repairing building cracks of this utility model:

[0037] First, secure the equipment to a suitable location for high-altitude operations using the fixing holes at the four corners of the mounting base 1, ensuring that the opening on the mounting base 1 is unobstructed below to guarantee equipment stability and prevent wobbling. Then, based on actual needs, utilize the design of the U-shaped frame 2 and the winding roller 20, along with the lifting rope 21 and lifting ring 44, to raise and lower the storage bin 4, adjusting it to a suitable height for easy delivery of repair materials to the crack.

[0038] Next, open the first sealing cover 42 on top of the storage silo 4, and add an appropriate amount of repair material into the storage silo 4 through the filling and discharging port 40. After adding the material, tighten the first sealing cover 42 again to ensure the airtightness of the storage silo 4 and prevent the repair material from leaking during transportation or storage.

[0039] Then, the storage bin 4 is raised and lowered and positioned between the two connecting seats 3. At this time, the two sealing covers inside the storage bin 4 are removed first, and then the threaded sleeves 33 on the two connecting seats 3 are tightened onto the outer wall of the storage bin 4.

[0040] When repair material needs to be injected into the crack, the air pump 5 is activated, and the air pump 5 inflates the storage hopper 4 through the first air supply pipe 51. As the air pressure increases, the repair material is propelled and discharged from the discharge pipe 31, entering the crack through the packing pipe 61 to repair the crack. During this process, the discharge speed of the repair material can be adjusted by controlling the air output of the air pump 5 to meet the repair needs of different cracks.

[0041] Meanwhile, this invention also includes an electromagnetic three-way valve 50 and a second air supply pipe 52, allowing the air pump 5 to simultaneously fill the storage hopper 4 with air and blow air into the cracks through the second air supply pipe 52. This allows the cracks to be cleaned by blowing air before the repair material is injected, removing debris and dust and improving the repair effect.

[0042] During the repair process, if the repair material in the storage bin 4 is exhausted, the storage bin 4 can be raised and lowered again to easily add more repair material. Meanwhile, since the storage bin 4 and the mounting base 1 are detachably connected via the mounting pipe 32 and threaded sleeve 33, the storage bin 4 can also be easily replaced or cleaned.

[0043] Furthermore, the design of the piston 45, which is slidably installed inside the storage bin 4, as well as the filling and discharging ports 40 and the air inlet 41, makes the feeding and discharging of repair materials more convenient. The limiting blocks 450 connected to the top and bottom of the piston 45 are slidably connected to the strip grooves 46 on the inner ring wall of the storage bin 4, which restricts the movement range of the piston 45 and prevents the piston 45 from derailing or being damaged during movement.

[0044] In summary, the building crack repair auxiliary device of this utility model, through its ingenious design, achieves efficient, convenient, and safe crack repair, greatly improving the efficiency and quality of building crack repair.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
