Specific embodiments

[0024] The following will describe the present utility model in detail with reference to the accompanying drawings.

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] A building crack vacuum treatment device, as Figures 1-5 shown, includes a base 1. A suction hole is provided in the middle of the base 1. Above the suction hole is provided a sealing cover 2. A groove is formed on the bottom surface of the sealing cover 2, and a rubber sealing ring 10 adapted to the specifications of the groove is fixedly installed on the bottom surface of the sealing cover 2; an air extraction hole 12 is provided on the sealing cover 2, and an air extraction pump 11 is correspondingly arranged outside the air extraction hole 12; a spraying tank 18 is provided inside the sealing cover 2, and a spray head 22 is connected below the spraying tank 18.

[0027] Through the settings of the air extraction pump 11, the air extraction hole 12 and the rubber sealing ring 10, the base 1 is covered on the crack. The rubber sealing ring 10 seals the periphery of the crack, and then the air extraction pump 11 is started, so that the air in the crack and inside the sealing cover 2 is discharged through the air extraction hole 12 to form a vacuum effect, and then the crack is sprayed and filled to prevent the phenomenon of cavities generated during filling, and improve the effect of crack treatment. Specifically, a sealing filler is assembled inside the spraying tank 18. Under vacuum conditions, the repair material can reach all positions of the crack well, and even reach some severely damaged areas, which is beneficial to a more complete repair. The through position of the crack and independent cracks can be detected in time. The device has its own adsorption function, which is convenient for on-site operation and repair work. In terms of modifying materials, since the nature and shape of the crack can be obtained, the selected materials only need to meet the requirements of filling the entire crack and having good cementing effect. In terms of on-site construction, mechanical automatic repair is adopted, which is beneficial to improving efficiency and the feasibility of convenient operation.

[0028] As another specific embodiment, chutes 13 are formed on the inner walls of the left and right sides of the sealing cover 2. A lead screw 14 sleeved on the output end of a motor is assembled in the chute 13. A slider 15 is slidably connected to the lead screw 14. A moving rod 16 is fixedly installed between the sliders 15. A moving trolley 17 is slidably connected to the outer wall of the moving rod 16. The injection tank 18 is fixedly installed on the bottom surface of the moving trolley 17. The sliders 15 and the moving trolley 17 can drive the nozzle 22 to move horizontally while injecting the sealing filler into the crack through the nozzle 22, improving the filling efficiency and ensuring the uniformity of filling.

[0029] As another specific embodiment, a fixed cylinder 19 is fixedly installed on the bottom surface of the injection tank 18. A connector 21 is assembled at the bottom of the fixed cylinder 19. A nozzle 22 communicated with the connector 21 is fixedly installed on the bottom surface of the connector 21. The connector 21 and the injection tank 18 are communicated through a connecting pipe 23. The position of the nozzle 22 can be fixed through the connector 21, and the injection tank 18 and the nozzle 22 can be communicated through the connecting pipe 23 to realize the transportation of the sealing injection filler.

[0030] As another specific embodiment, an infrared sensor 24 is fixedly installed on the bottom surface of the connector 21. The length and shape of the crack can be measured through the infrared sensor 24 and sensed. The sliders 15 and the moving trolley 17 move according to the actually measured values to ensure the filling accuracy.

[0031] As another specific embodiment, a plurality of suction cups 3 are provided at the bottom of the base 1. The suction cups 3 are adapted to the height of the rubber sealing ring 10. The plurality of suction cups 3 are evenly distributed around the suction holes. The device as a whole can be adsorbed on the ground or the wall. Further, the suction cups 3 include four.

[0032] As another specific embodiment, a fixed sleeve 4 opposite to and communicated with the suction cup 3 is fixedly installed on the top surface of the base 1. A sliding sleeve 6 with a suitable specification and capable of relative movement is assembled on the outer wall of the fixed sleeve 4. A connecting rod 8 is fixedly installed on the inner wall of the top surface of the sliding sleeve 6. A piston plate 9 located on the inner wall of the fixed sleeve 4 is fixedly installed at the bottom end of the connecting rod 8. Further, the suction cup 3 is arranged at the bottom of the piston plate 9. Through the relatively movable fixed sleeve 4 and sliding sleeve 6, the piston plate 9 can be driven to move, and then the suction cup 3 can move up and down to be adsorbed on the ground or the wall.

[0033] As another specific embodiment, a threaded groove 5 is formed on the outer wall of the fixed sleeve 4. A thread 7 with a suitable specification is assembled on the inner wall of the sliding sleeve 6. Thus, the positions of the fixed sleeve 4 and the sliding sleeve 6 are relatively fixed, preventing the suction cup 3 from becoming loose and ensuring the adsorption stability.

[0034] As another specific embodiment, an electric telescopic rod 20 is fixedly installed on the inner wall of the top surface of the fixed cylinder 19. The bottom end of the electric telescopic rod 20 is fixedly connected to a connector 21, and the connector 21 is slidably connected to the fixed cylinder 19. The electric telescopic rod 20 drives the spray head 22 to move downward, which also improves the stability of the movement of the spray head 22. The spray head 22 can move up and down. Starting from the bottom layer for filling, it ensures that each layer has sufficient support. The gradually increasing number of layers can improve the structural stability and prevent the filling material from falling due to gravity, resulting in voids or uneven density in the lower layer, which affects the filling effect and strength.

[0035] As another specific embodiment, a laser rangefinder is fixedly installed on the bottom surface of the connector 21. It can measure the depth of the crack.

[0036] As another specific embodiment, it further includes a controller 26, and the controller 26 is fixedly installed on one side of the sealing cover 2. It is convenient to control each component and improve the automation.

[0037] The working process of a building crack vacuum treatment device provided by this embodiment is as follows:

[0038] When the device needs to be used, first cover the base 1 on the crack, then adsorb the device on the wall or the ground through the piston plate 9 and the suction cup 3. The rubber sealing ring 10 seals the periphery of the crack, and then start the air pump 11, so as to discharge the air in the crack and the sealing cover 2 through the air extraction hole 12 to form a vacuum effect. The infrared sensor 24 and the laser rangefinder 25 respectively measure the shape and depth of the crack. The electric telescopic rod 20 first drives the spray head 22 to the bottom of the crack, and then the slider 15 and the mobile trolley 17 drive the spray head 22 to move horizontally while spraying the sealing filler on the crack through the spray head 22. After the bottom layer of the crack is sprayed, the electric telescopic rod 20 drives the spray head 22 to retract, and then spray the crack again, and so on until the crack is completely filled.
