These components can include walls, floors, stairs, balconies, etc., and they are usually designed in a standardized manner to facilitate quick and efficient on-site installation.

[0003] In the modern construction industry, prefabricated buildings are widely used due to their advantages such as high efficiency, environmental protection and energy saving. However, these prefabricated components are prone to cracks during transportation, installation and use, which affects the structural integrity and appearance quality of the building. Traditional crack repair methods usually require manual operation, which is inefficient and difficult to guarantee the repair effect. Therefore, we need to propose a crack repair device for prefabricated building components. Utility Model Content

A rotating ring 20 is rotatably mounted on one side of the support plate 11, and a support rod 21 is rotatably mounted on the inner wall of the rotating ring 20. The trolley 1 serves as the base platform for the entire equipment. The bottom of the trolley 1 is equipped with wheels, making it easy for operators to move the equipment to a position next to large building components. The trolley 1 has a stable structure and can bear the weight of other components. The material cylinder 2 is used to store sealant. The top rod 9 is designed to be stable and reliable, ensuring the stability of the support plate 11. The collar 10 is used to enhance the connection stability between the top rod 9 and the support plate 11. The collar 10 has a simple and practical design, and is easy to install and disassemble. The material cylinder 2 is designed to be easy to disassemble and reinstall, making it convenient for operators to fill or replace sealant.

[0025] The base rod 7 has multiple through holes 22 on its outer side. Multiple auxiliary plates 23 are fixedly connected to the outer side of the base rod 7. Two auxiliary plates 23 have rotating rollers 24 rotatably mounted inside them. A pull rod 25 is fixedly connected to the outer side of the rotating roller 24. A pawl 26 is rotatably mounted inside the pull rod 25. A strong spring plate 27 is fixedly connected to the outer side of the base rod 7. Two auxiliary plates 23 have L-shaped claws 28 rotatably mounted inside them. Through the ratchet 26, the base rod 7 serves as a crucial support structure for the equipment.

[0026] The repair component includes a slurry pump 3, which is located on one side of the material cylinder 2. The drive end of the slurry pump 3 is connected to a pipe 4, and the end of the pipe 4 away from the slurry pump 3 is connected to a nozzle 5. The top and bottom of the nozzle 5 are fixedly connected to a cylinder shaft 6. With the arrangement of the repair component, the slurry pump 3 is the core part of the repair component. The slurry pump 3 is responsible for drawing sealant from the material cylinder 2 and delivering it to the nozzle 5 through the pipe 4. The slurry pump 3 has a strong drawing capacity, which can ensure the continuous and stable output of sealant. The cylinder shaft 6 enables the nozzle 5 to remain stable at different angles, ensuring that the sealant can be accurately sprayed into the gap and smoothed out.

[0027] Rotating rod 14 is slidably mounted on the outside of support plate 11. The ends of two sets of connecting rods 15 away from rotating rod 14 are rotatably mounted on one side of nozzle 5. The rotating rod 14 is set to achieve stable rotation. Rotating rod 14 pulls connecting rod 15 to rotate. The right ends of the two connecting rods 15 are rotatably connected to the top left side of nozzle 5. The rotating rod will drive connecting rod 15 and the top of nozzle 5 to move together, thereby achieving adjustment of the upper side of nozzle 5.

[0028] The second rotating shaft 17 is slidably set on the outside of the support plate 11. The ends of the two sets of connecting rods 19 away from the first rotating rod 14 are rotatably installed on one side of the nozzle 5. One end of the support rod 21 is fixedly connected to one side of the nozzle 5. The longitudinal angle of the nozzle 5 is changed by driving the second rotating shaft 17 and the second rotating rod 18 through the second motor 16. The rotating ring 20 restricts the sliding position of the support rod 21 and provides certain support for the middle part of the nozzle 5 by limiting the sliding distance of the support rod 21.

[0029] The outer side of the pawl 26 engages with the outer side of the spur 8, and the outer side of the L-shaped pawl 28 engages with the outer side of the spur 8. The arrangement of the pawl 26, the spur 8, and the L-shaped pawl 28 facilitates the adjustment of the height of the spur 8.

[0030] The bottom of the slurry pump 3 is fixedly connected to the top of the trolley 1. The top of the trolley 1 is fixedly connected to the clamp 31. With the clamp 31, when the bottom rod 7 is not in use, the bottom rod 7 can be placed in the clamp 31 for storage, providing storage space for the bottom rod 7.

[0031] A second button 30 is provided on the outer side of the bottom end of the base rod 7, and a first button 29 is provided on the outer side of the top end of the base rod 7. The second button 30 is electrically connected to the first motor 12, and the first button 29 is electrically connected to the second motor 16. Through the setting of the first button 29 and the second button 30, the second button 30 facilitates the operator to control the start of the first motor 12, and the first button 29 facilitates the operator to control the start of the second motor 16.

[0032] Working principle: When using this utility model, filler is poured into the cylinder 2, and then the device is moved to a suitable position next to the large building component. After moving it, the pull rod 25 is pressed repeatedly, causing the pull rod 25 to rotate around the roller 24. This causes the pawl 26 connected to the front of the pull rod 25 to slide downwards against the outside of the ratchet 8. At this time, due to the repeated up and down movement of the pull rod 25, and the fact that the outside of the ratchet 8 is a rod composed of multiple conical cylinders, the pawl 26 will be driven by the pull rod 25 to slide downwards at a node of the outer cylinder of the ratchet 8. Then, it will engage the next cylinder node of the ratchet 8, pushing the cylinder upwards. Simultaneously, the top of the L-shaped claw 28 will also slide synchronously with the pawl 26 and be stopped by the top spring of the strong spring plate 27, stopping the next cylinder node of the previously engaged cylinder. This fixes the length of the ratchet 8, allowing the operator to stably and quickly adjust the length of the ratchet 8 and the bottom rod 7 so that the nozzle 5 can reach the appropriate position of the large building component for filling and repair work.

[0033] When the height of the ratchet 8 needs to be adjusted, simply press the pull rod 25 downwards and the end with the L-shaped claw 28 facing outwards downwards to allow the ratchet 8 to slide slowly and retract into the base rod 7.

[0034] After the lengths of the base rod 7 and the ratchet 8 are adjusted, the operator can place the nozzle 5 close to the gap of the building component, start the slurry pump 3, and let the slurry pump 3 draw the sealant in the material cylinder 2 and spray it out through the pipe 4 and the nozzle 5 nozzle. With the sliding nozzle 5 on the surface of the gap, the cylinder shaft 6 smooths the sealant sprayed into the gap.

[0035] When it is necessary to repair gaps in building components at different locations and angles, pressing button 230 will start motor 12. Motor 12 drives rotating rod 14 and connecting rod 15 to rotate, causing connecting rod 15 to pull the top of nozzle 5 to move. Then, button 129 controls motor 216, which drives rotating shaft 217 and rotating rod 218 to rotate, causing rotating rod 218 to pull the bottom of nozzle 5 to move. The middle support rod 21 of nozzle 5 will slide inside the rotating ring 20 to maintain the stability of nozzle 5. As the angle of connecting rod 15 and connecting rod 219 changes, the longitudinal angle of nozzle 5 changes, allowing nozzle 5 to better fit gaps at different angles and positions for filling operations.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
