Description

Technical Field

[0001] This utility model relates to the technical field of building exterior wall repair devices, and in particular to a building exterior wall repair device. Background Technology

[0002] Over time, building exteriors are subjected to natural erosion from wind, sun, and rain. Ultraviolet radiation can cause exterior paint to fade and chalk, reducing its decorative and protective properties. Rainwater seepage can easily lead to cracks and hollow areas in the walls, and in severe cases, damage to the wall structure. Taking southern my country as an example, frequent rainy seasons result in varying degrees of leakage in the exterior walls of many buildings, with leakage areas reaching 30%-40%. In northern China, the freezing-thaw cycle in winter can cause the exterior wall insulation layer to crack and peel off, affecting the building's insulation performance and aesthetics. To extend the lifespan of buildings, regular repairs of the exterior walls are necessary.

[0003] Traditional exterior wall repairs often rely on manual labor, using tools such as rollers and trowels to apply repair materials to the damaged areas. The rollers pick up the repair fluid and apply it to the exterior wall surface. Since the roller bristles have limited capacity to absorb the repair fluid, the manual hand holds the roller and frequently picks up the repair fluid. This repair method is cumbersome, wastes a lot of time, and greatly reduces the efficiency of building repairs. Furthermore, the large-scale movement of the roller can cause the repair fluid to splash, resulting in large-scale pollution of the building floor. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a house exterior wall repair device that can automatically replenish repair fluid and prevents the repair fluid from splashing.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a base, a pump body, a roller brush assembly, and a material conveying assembly. The upper surface of the base is provided with a first placement frame and a second placement frame facing away from each other. The pump body is disposed between the first placement frame and the second placement frame. One end of the roller brush assembly is connected to the output end of the pump body through the first placement frame, and the other end of the roller brush assembly is matched with the upper limit of the first placement frame. One end of the material conveying assembly is connected to the input end of the pump body through the second placement frame, and the other end of the material conveying assembly is matched with the upper limit of the second placement frame.

[0006] Furthermore, the roller brush assembly includes a delivery pipe, a first telescopic pipe, a liquid outlet pipe, and a roller brush component. The delivery pipe, the first telescopic pipe, and the liquid outlet pipe are connected in sequence. One end of the delivery pipe passes through the first placement frame (which is connected to the output end of the pump body). The upper part of the liquid outlet pipe is provided with two branch pipes with opposite ports. Each branch pipe is rotatably connected to one end of the roller brush component.

[0007] Furthermore, the roller brush includes a cylinder, connecting pipes disposed at both ends of the cylinder, and brush bristles disposed on the outer wall of the cylinder. Each connecting pipe is rotatably connected to a corresponding branch pipe. A flow cavity for the flow of repair fluid is formed in the middle of the cylinder. Multiple infusion ports communicating with the flow cavity are equally spaced along the length direction on the outer wall of the cylinder.

[0008] Furthermore, the upper part of the first placement rack is formed with a first groove for guiding and engaging the liquid outlet pipe, and the outer peripheral wall of the liquid outlet pipe is provided with a first limiting ring, which engages with the upper part of the first placement rack.

[0009] Furthermore, a reinforcing plate is provided in the middle of the first placement rack, and a reserved groove is provided in the middle of the reinforcing plate to cooperate with the first telescopic tube guide. Both the reserved groove and the first slot are fixedly connected with rubber pads for increasing friction.

[0010] Furthermore, the material conveying assembly includes a feed pipe, a second telescopic pipe, and a suction pipe. One end of the feed pipe passes through the second placement plate and is connected to the input end of the pump body. The other end of the feed pipe is connected to one end of the second telescopic pipe, and the other end of the second telescopic pipe is connected to the suction pipe. The upper part of the suction pipe is limited and engaged with the second placement plate.

[0011] Furthermore, a second slot is formed on the upper part of the second placement frame, and a second limiting ring is formed on the material extraction tube to cooperate with the limiting of the second placement frame. The diameter of the second limiting ring is larger than the diameter of the second slot.

[0012] Furthermore, several casters are fixedly connected to the lower surface of the base.

[0013] The beneficial effects of this utility model are as follows: Because this utility model uses the pump body's own suction to stably transport the repair fluid from the storage container through the extraction pipe and inlet pipe to the delivery pipe, the stable delivery process ensures the timely supply of repair materials, avoiding the tedious steps of manually using a hand-held roller to frequently pick up the repair fluid, saving a significant amount of time and greatly improving the efficiency of house repairs. Furthermore, the roller does not require extensive movement, preventing the repair fluid from splashing and improving the cleanliness of the building floor. The first and second telescopic pipe structures increase the working range of the roller brush assembly and the material delivery assembly, facilitating workers to repair walls using the roller brush and to draw repair fluid from the storage container. The first rubber pad increases the friction between the rubber pad and the pipe placed in the slot, preventing the pipe from shaking or slipping in the slot, and also provides a certain buffering effect, protecting the pipe from being scratched by the slot.

Detailed Implementation

[0021] like Figures 1 to 6 As shown, in this embodiment, the present invention includes a base 1, a pump body 2, a roller brush assembly 3, and a material conveying assembly 4. A first placement frame 5 and a second placement frame 6 are disposed opposite to each other on the upper surface of the base 1. The pump body 2 is disposed between the first placement frame 5 and the second placement frame 6. One end of the roller brush assembly 3 is connected to the output end of the pump body 2 through the first placement frame 5, and the other end of the roller brush assembly 3 is engaged with the upper limit of the first placement frame 5. One end of the material conveying assembly 4 is connected to the input end of the pump body 2 through the second placement frame 6, and the other end of the material conveying assembly 4 is engaged with the upper limit of the second placement frame 6.

[0022] The pump body 2 uses its own suction to stably transport the repair fluid from the storage container through the extraction pipe 43 and the inlet pipe 41 to the delivery pipe 31. The stable delivery process ensures the timely supply of repair materials, avoids the tedious steps of frequently picking up repair fluid with a hand-held roller brush, saves a lot of time, greatly improves the efficiency of house repair, and the roller brush does not need to move a large range, so it will not cause the repair fluid to splash, thus improving the cleanliness of the building floor.

[0023] High-quality rubber casters 7 installed around the bottom of the base plate reduce wear and tear during frequent movement, lower maintenance costs, and extend the lifespan of the device. Excellent steering flexibility allows operators to easily maneuver the device in complex construction sites, navigating smoothly through narrow spaces or areas with many obstacles. When repairing the exterior walls of multi-story buildings, it can quickly reach the repair area along the building's perimeter, significantly shortening positioning time and improving construction efficiency. Compared to the traditional method of manually moving equipment to a designated location, it saves considerable manpower and time costs, enabling faster repair work and minimizing disruption to residents' lives.

[0024] In this embodiment, the roller brush assembly 3 includes a delivery pipe 31, a first telescopic pipe 32, a liquid outlet pipe 33, and a roller brush 34. The delivery pipe 31, the first telescopic pipe 32, and the liquid outlet pipe 33 are connected in sequence. One end of the delivery pipe 31 passes through the first placement frame 5 and communicates with the output end of the pump body 2. The upper part of the liquid outlet pipe 33 is provided with two branch pipes 35 with opposite ports. Each branch pipe 35 is rotatably connected to one end of the roller brush 34.

[0025] In this embodiment, the roller brush 34 includes a cylinder 341, connecting pipes 342 disposed at both ends of the cylinder 341, and bristles 343 disposed on the outer wall of the cylinder 341. Each connecting pipe 342 is rotatably connected to a corresponding branch pipe 35. A flow cavity 344 for the flow of repair fluid is formed in the middle of the cylinder 341. Multiple infusion ports 345 communicating with the flow cavity 344 are evenly spaced along the length of the outer wall of the cylinder 341. The bristles 343 are made of soft and elastic nylon material, which can evenly cover the wall surface when applying repair material without damaging the wall surface. Multiple infusion ports 345 are evenly distributed around the core of the inner tube of the connecting pipe 342. When the repair material enters the connecting pipe 342 through the branch pipe 35 and the connecting pipe 342, it will flow out through the infusion ports 345, wetting the bristles 343, thereby realizing the application and repair of the wall surface.

[0026] In this embodiment, the upper part of the first placement frame 5 has a first groove 51 for guiding and engaging the liquid outlet pipe 33. The outer peripheral wall of the liquid outlet pipe 33 is provided with a first limiting ring 36, which engages with the upper part of the first placement frame 5. The diameter of the first limiting ring 36 is larger than the diameter of the first groove 51. The first limiting ring 36 can effectively prevent the material extraction pipe 43 from coming out of the groove, ensuring the stability of the relevant pipelines of the roller assembly in the device.

[0027] In this embodiment, a reinforcing plate 52 is provided in the middle of the first placement rack 5. A reserved groove 53 is provided in the middle of the reinforcing plate 52 to cooperate with the first telescopic tube 32 guide. Both the reserved groove 53 and the first slot 51 are fixedly connected with rubber pads 54 for increasing friction.

[0028] The function of rubber pad 54 is to increase the friction between the rubber pad and the pipe placed in the slot, to prevent the pipe from shaking or slipping in the slot, and at the same time, it can also play a certain role in cushioning and protecting the pipe from being scratched by the slot.

[0029] In this embodiment, the material conveying assembly 4 includes an inlet pipe 41, a second telescopic pipe 42, and an extraction pipe 43. One end of the inlet pipe 41 passes through the second placement plate 6 and connects to the input end of the pump body 2. The other end of the inlet pipe 41 is connected to one end of the second telescopic pipe 42, and the other end of the second telescopic pipe 42 is connected to the extraction pipe 43. The upper part of the extraction pipe 43 is engaged with the second placement plate 6 for limiting. The extraction pipe 43 is used to insert into the storage container to extract repair material. The pump body 2 sucks in the repair material through the inlet pipe 41 and delivers it to the conveying pipe 31, thereby realizing the repair operation on the wall surface.

[0030] In this embodiment, a second slot 61 is formed on the upper part of the second placement frame 6, and a second limiting ring 44 is formed on the material extraction tube 43 to limit and cooperate with the second placement frame 6. The diameter of the second limiting ring 44 is larger than the diameter of the second slot 61. The diameter of the second limiting ring 44 is larger than the diameter of the second slot, and the second limiting ring 44 can effectively prevent the material extraction tube 43 from falling out of the slot, ensuring the stability of the material conveying assembly 4 in the device.

[0031] In this embodiment, a number of casters 7 are fixedly connected to the lower surface of the base 1.

[0032] The 7 casters are made of high-quality rubber, which has good wear resistance and steering flexibility. This design allows the device to be easily moved on the construction site, making it convenient for operators to flexibly adjust it according to the specific location of the exterior wall repair.

[0033] The working principle of this utility model:

[0034] The operator pushes the device to move on the construction site and adjusts it flexibly according to the specific location of the exterior wall repair. For example, when repairing the exterior wall of a multi-story building, it can quickly reach the repair area along the perimeter of the building. At the top bend of the second placement frame 6, the material conveying pipe assembly is connected through the second slot. The material extraction pipe 43 is used to insert into the storage container to extract the repair material. After the pump body 2 is started, it uses its own suction to transport the repair material sucked in by the material extraction pipe 43 from the storage container to the conveying pipe 31 through the feed pipe 41.

[0035] Pump body 2 outputs repair material from delivery pipe 31, which then enters outlet pipe 33 through first telescopic pipe 32. During use, the operator can quickly remove outlet pipe 33 from first placement rack 5. Repair material enters connecting pipe 342 through branch pipe 35 and connecting pipe 342. Multiple infusion ports 345 are evenly distributed around the core of the connecting pipe 342. Material flows out from infusion port 345, wetting the bristles 343 on the outer surface of cylinder 341. Repair liquid is continuously delivered to the bristles 343 on the outside of cylinder 341 through the pipeline. There is no need for frequent manual application of repair liquid. The operation steps are simple, time is saved, and the efficiency of house repair is effectively improved.

[0036] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
