Description

Technical Field

[0001] This utility model relates to the field of filling devices, and in particular to a filling device for building reinforcement. Background Technology

[0002] Wall cracks are cracks that occur in the wall parts of a building structure. Existing concrete structures have developed cracks of varying degrees and styles during construction and use. The expansion of cracks will cause leakage in the structure, reduce the structure's stiffness, durability, and seismic performance. As the cracks develop further, they may threaten human life and property safety. Cracks are an important indicator of damage to concrete buildings. Cracks are generally linear and will continue to extend if not repaired, causing the cracks to become longer.

[0003] In existing technologies, when cracks appear on building walls, the usual method of filling and reinforcing them is to manually inject grout into the cracks using a handheld crack-reinforcing syringe. However, this filling device is inconvenient to operate on cracks in some interior walls because the cracks are located too high and are scattered. This means that manual filling and reinforcement requires the use of ladders or scaffolding to climb to higher positions, which is not only cumbersome but also poses safety hazards and reduces the efficiency of filling and reinforcing the building. Utility Model Content

[0004] The main objective of this invention is to provide a filling device for building reinforcement, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A filling device for building reinforcement includes a base, with casters fixedly installed at the four corners of the base's bottom surface. A filling mechanism is provided on the top surface of the base, comprising a vertical plate, a fixed plate, a material hopper, a pump body, a pressure valve, a delivery pipe, an injection nozzle, a lead screw, a drive motor, and an adjusting plate.

The lead screw is movably connected between the fixed plates via rotating rods at both ends, and the drive motor is fixedly connected to the lower fixed plate. The bottom surface of the fixed plate, the output end of the drive motor is fixedly connected to the rotating rod, the adjusting plate is movably connected to the lead screw through the connecting plate at the bottom right side and passes through the vertical plate, the material box is fixedly connected to the top surface of the base, and the pump body is fixedly connected to the right side of the material box, the input end of the pump body is fixedly connected to the discharge pipe at the bottom right side of the material box, and a pressure valve is also fixedly connected to the output end of the pump body, the right end of the pressure valve is fixedly connected to the conveying pipe, and the conveying pipe is fixedly connected to the adjusting plate through the pipe clamp, and the injection nozzle is fixedly connected to the top end of the conveying pipe.

[0008] Preferably, rotating rods are fixedly installed at the upper and lower ends of the lead screw, and the rotating rods are movably installed in the rotating holes. The drive motor is fixedly installed on the bottom surface of the lower fixing plate, and the output end of the drive motor is fixedly installed together with the rotating rod at the lower end.

[0009] Preferably, a connecting plate is fixedly installed on the bottom right side of the adjusting plate, and the connecting plate is movably installed in the vertical opening and passes through the vertical opening.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the filling mechanism uses wheels on the base to move the entire device to the area below the crack in the building wall, aligning the injection nozzle with the crack. The drive motor is activated, driving the output end to rotate the lead screw via a rotating rod. This causes the adjusting plate to move upwards along the lead screw via a connecting plate. During this movement, the material delivery pipe is moved via a pipe clamp until the injection nozzle at the top of the delivery pipe contacts the crack. Then, the pump is activated to extract the filling and reinforcement slurry from the hopper and deliver it to the delivery pipe. The pressure is adjusted by a pressure valve. Finally, the slurry is injected through the injection nozzle into the crack to fill it. This allows personnel to quickly reinforce and fill cracks in high-altitude building walls without climbing, making the operation simple and convenient. This not only avoids safety hazards but also improves work efficiency. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 - Figure 3 As shown, in this embodiment, in order to facilitate workers to complete the reinforcement and filling operation of cracks appearing on the top of the building wall without having to climb, thereby improving work efficiency, the specific operating principle of the filling mechanism 3 is as follows:

[0020] First, the entire device is moved to the location below the crack in the building wall using the casters 2 installed at the four corners of the base 1, aligning the injection nozzle 14 with the crack. Then, the drive motor 17, mounted on the bottom of the fixing plate 6 on the lower right side of the vertical plate 4, is activated. The drive motor 17 drives the rotating rods 16, mounted at both ends of the lead screw 15, to rotate within the rotating holes 7 on the top surface of the symmetrical fixing plates 6 on the right side of the vertical plate 4. The rotating rods 16 then drive the lead screw 15 to rotate between the symmetrical fixing plates 6. When the lead screw 15 rotates, the connecting plate 19 is threadedly connected to the lead screw 15 through the screw hole 20 on its top surface. Therefore, the connecting plate 19 moves upward along the lead screw 15 through the screw hole 20 and slides in the vertical opening 5 on the side wall of the vertical plate 4. This causes the adjusting plate 18 on the left side of the vertical plate 4 to move upward synchronously. During this movement, the upper end of the conveying pipe 13 is fixed to the adjusting plate 18 through the pipe clamp 21 installed at the top of the left side wall of the adjusting plate 18. Therefore, the adjusting plate 18 will... The feed pipe 13 is moved upward until the injection nozzle 14 installed at the top of the output end of the feed pipe 13 contacts or is inserted into the crack in the wall. Then, the pump body 11 installed on the top surface of the base 1 is turned on. The output end of the pump body 11 will extract the slurry for reinforcement and filling that has been pre-added into the material tank 8 through the feed port 9 on the top surface of the material tank 8 through the discharge pipe 10 installed at the bottom right side of the left material tank 8, and deliver it to the feed pipe 13 through the output end. When the pump body 11 delivers the slurry into the feed pipe 13, the pressure valve 12 installed on the output end of the pump body 11 can be used to control the flow. The pressure during conveying is adjusted to prevent excessive or insufficient pressure. Finally, the slurry is sprayed out through the injection nozzle 14 at the top of the conveying pipe 13 and injected into the crack to fill it. After completing the crack filling and reinforcement operation, the entire device can be moved directly to the next crack and the above operation is repeated until all wall top cracks are filled and reinforced. This allows personnel to quickly complete the reinforcement and filling operation of high-rise building wall top cracks without having to climb to a height. The operation is simple and convenient, which not only avoids safety hazards but also improves work efficiency.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
