Description

Technical Field

[0002] Reinforced concrete prefabricated components are a green and low-carbon construction method. In actual production, tiny holes will appear on the surface of the structure after demoulding. These tiny holes will not affect the performance of concrete structures such as walls, columns and composite floor slabs during actual use. However, the repair of wall panels plays an important role in purchasing and inspecting quality. At present, the repair method for prefabricated components mostly adopts manual repair method. The components that need to be repaired are cleaned with a brush and then repaired with cement mortar. The type of cement must be consistent with the original concrete.

[0048] Example 2

[0049] Reference Figure 1-Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0050] Specifically, the probe detection device 206 includes a support rod 206a, which is fixed to one side of the turntable 205. A mounting plate 206b is fixed to one side of the support rod 206a. A stabilizing block 206c is fixed to one side of the mounting plate 206b through a connecting plate. A probe 206d is inserted into the stabilizing block 206c. A spring 206e is fixed to one end of the probe 206d. One end of the spring 206e is fixed to the mounting plate 206b. A sensor 206f is provided on one side of the stabilizing block 206c. The sensor 206f is used to detect the moving stroke of the probe 206d.

[0051] There are multiple probes 206d and springs 206e, which are evenly distributed in a rectangular shape on the stabilizing block 206c. The probe 206d is brought into contact with the top of the prefabricated component and pressed downward. When part of the probe 206d enters the hole, the other probes 206d will move. As the mounting plate 206b continues to move, when the probe 206d that enters the hole contacts the inner wall of the hole, the part of the probe 206d will also move. In this way, the travel of the probe 206d into the hole can be detected by the sensor 206f, so as to judge the depth of the hole.

[0052] Specifically, a second screw conveyor 301 a is disposed in the powder storage box 301 , and the second screw conveyor 301 a is connected to the stirring box 303 .

[0053] The second screw conveyor 301 a is used to quantitatively convey the cement powder in the powder storage box 301 to the mixing box 303 .

[0054] Specifically, a connecting pipe 302a is fixed to one side of the water storage tank 302, one end of the connecting pipe 302a is connected to the mixing tank 303, a water pump 302b is arranged on the connecting pipe 302a, and a water flow detection sensor 302c is arranged in the connecting pipe 302a.

[0055] The connecting pipe 302a cooperates with the water pump 302b to transport the water in the water storage tank 302 to the mixing box 303, and the water flow rate is detected by the water flow detection sensor 302c, so that the water entering the mixing box 303 can be accurately controlled.

[0056] Specifically, a feeding pipe 303a is provided in the mixing box 303, and a feeding pump 303b is provided on one side of the mixing box 303, and the feeding pump 303b is connected to the feeding pipe 303a.

[0057] The feeding pipe 303 a is in communication with the first screw conveyor 304 inside the support block 203 . The feeding pipe 303 a and the feeding pump 303 b are arranged to convey the mixed cement slurry to the first screw conveyor 304 .

[0058] Specifically, a gear ring 205a is fixed to one side of the rotating disk 205, a motor 205b is fixed to the bottom of the supporting block 203, a gear 205c is fixed to the output shaft of the motor 205b, and the gear 205c is meshed with the gear ring 205a.

[0059] The motor 205b is used to drive the gear 205c to rotate, and drives the ring gear 205a to rotate through the gear 205c, so that the rotating disk 205 can be driven to rotate through the ring gear 205a.

[0060] Example 3

[0061] Reference Figure 1-Figure 8, which is the third embodiment of the present invention, and is based on the first two embodiments.

[0062] Specifically, the water flow monitoring device 208 includes a water tank 208a, which is disposed on the mechanical arm 202. A water pipe 208b is fixed to the outside of the mechanical arm 202, and one end of the water pipe 208b is connected to the water tank 208a.

[0063] There are four water pipes 208b, which are fixed in a ring shape around the outer side of the robotic arm 202. The water pipe 208b and the robotic arm 202 can be fixed by gluing. The water pipe 208b needs to fit the robotic arm 202. The top ends of two adjacent water pipes 208b are connected, and the bottom ends are connected to the water tank 208a. A delivery pump is provided in the water pipe 208b, which is used to deliver the water inside the water pipe 208b to the water pipe 208b. Then, after the water circulates in the water pipe 208b for one circle, it will flow back to the water tank 208a through the adjacent water pipe 208b. When the robotic arm 202 is stuck or jammed during the bending process, the bent water pipe 208b will hinder the normal flow of water. At this time, the water flow state sensor inside the water tank 208a detects that the robotic arm 202 is in a stuck state, so that the robotic arm 202 can be repaired in time.

[0064] The water tank 208a is fixed to the outer bottom of the robot arm 202 and can rotate along with the robot arm 202, thereby preventing the water pipe 208b from being pulled when the robot arm 202 rotates.

[0065] Specifically, the optical device 204 includes an illumination device 204a and a light sensing device 204b. The illumination device 204a emits strong light perpendicular to the prefabricated component, and the light sensing device 204b collects reflected light from the prefabricated component for data analysis.

[0067] Specifically, a positioning plate 103 a is fixed to one side of the support plate 103 , a scraper 103 b is fixed to one side of the positioning plate 103 a , and a brush 103 c is fixed to the bottom of the positioning plate 103 a .

[0068] The scraper 103b is inclined. When the support plate 103 moves, the scraper 103b can be driven to scrape the dust inside the slide rail 102, and the brush 103c can be used to clean the dust inside the slide rail 102, so as to avoid the slider 104 from getting stuck when moving in the slide rail 102.

[0069] When in use, the prefabricated component is first transported to the detection position through the cooperation of the support plate 103 and the slide rail 102 .

[0070] At this time, rotate the turntable 205, point the optical device 204 toward the prefabricated component, and then use the mechanical arm 202 to drive the optical device 204 to move on the surface of the prefabricated component, and use the optical device 204 to detect the holes on the surface of the prefabricated component. When holes are detected.

[0071] The probe detection device 206 is rotated to a position facing the surface of the prefabricated component by the turntable 205, and the probe detection device 206 is pressed against the surface of the prefabricated component. At this time, part of the probe 206d will enter the hole, and the probe 206d will not move in the stabilizing block 206c, while the probe 206d that has not entered the hole will move in the stabilizing block 206c. At this time, the moving trajectory of the probe 206d is detected by the sensor 206f, so that the depth of the hole can be known.

[0072] At the same time, part of the powder is conveyed to the mixing box 303 through the second screw conveyor 301a, and then part of the water is conveyed to the mixing box 303 through the connecting pipe 302a. At this time, the two are mixed through the mixing box 303, and then the mixed cement slurry is conveyed to the first screw conveyor 304 through the feeding pipe 303a. The cement slurry is conveyed to the nozzle 305 through the first screw conveyor 304, and the cement slurry is quantitatively sprayed into the hole through the nozzle 305 to complete the repair of the hole. If the holes on the four sides of the prefabricated component are to be repaired, more powder and less water are required to increase the viscosity of the cement slurry and prevent the cement slurry from flowing downward.

[0073] At this time, the scraper 402 is brought into contact with the surface of the prefabricated component through the rotating disk 205, and the scraper 402 is used to scrape off the excess cement slurry, and the scraped waste is sucked into the storage box 404 through the suction pipe 403 for storage.

[0074] Finally, the wedge-tip interference device 207 is attached to the surface of the prefabricated component and cooperated with the optical device 204 to detect whether the hole is repaired.

10. A method for repairing holes on the surface of an assembled prefabricated component, characterized in that: The repair device comprises any one of claims 1 to 9, and the repair method comprises: First, the prefabricated component is transported to the inspection position through the cooperation of the support plate (103) and the slide rail (102); At this time, the turntable (205) is rotated to direct the optical device (204) toward the prefabricated component, and then the mechanical arm (202) drives the optical device (204) to move on the surface of the prefabricated component, and the optical device (204) detects holes on the surface of the prefabricated component. When holes are detected; The probe detection device (206) is rotated to a position facing the surface of the prefabricated component by means of a rotating disk (205), and the probe detection device (206) is pressed against the surface of the prefabricated component. At this time, part of the probe (206d) will enter the hole, and the probe (206d) will not move in the stabilizing block (206c), while the probe (206d) that has not entered the hole will move in the stabilizing block (206c). At this time, the movement trajectory of the probe (206d) is detected by means of a sensor (206f), so that the depth of the hole can be known; At the same time, part of the powder is conveyed to the mixing box (303) through the second screw conveyor (301a), and then part of the water is conveyed to the mixing box (303) through the connecting pipe (302a). At this time, the two are mixed through the mixing box (303), and then the mixed cement slurry is conveyed to the first screw conveyor (304) through the feeding pipe (303a). The cement slurry is conveyed to the nozzle (305) through the first screw conveyor (304), and the cement slurry is quantitatively sprayed into the hole through the nozzle (305) to complete the repair of the hole. If the holes on the four sides of the prefabricated component are to be repaired, more powder and less water are required, so as to increase the viscosity of the cement slurry and prevent the cement slurry from flowing downward; At this time, the scraper (402) is brought into contact with the surface of the prefabricated component through the rotating disk (205), and the excess cement slurry is scraped off by the scraper (402), and the scraped waste is sucked into the storage box (404) through the suction pipe (403) for storage; Finally, the wedge-tip interference device (207) is attached to the surface of the prefabricated component and cooperated with the optical device (204) to detect whether the hole has been repaired.
