The existing construction technology for plugging external wall screw holes has low construction efficiency, poor plugging density, a high risk of leakage and moisture return, and high labor costs. Workers need to manually plug the screw holes one by one. The number is large and the workload is heavy, which limits the efficiency of the entire project.

[0003] Therefore, the known screw hole plugging methods have the above-mentioned various inconveniences and problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a safe and reliable plugging device for the screw holes of an external hanging scaffold.

[0015] The present invention will be further described below in conjunction with the embodiments and their accompanying drawings.

[0016] Embodiment 1

[0017] Now please refer to Figures 1-3 , the plugging device for the external hanging frame screw holes of the present invention includes a base 1 and a bracket 3.

[0018] A plurality of mounting holes 18 are provided around the base 1, and a roller 2 is rotatably mounted in each mounting hole 18.

[0019] A plurality of openings are provided on the bracket 3, and arc-shaped supporting pieces 12 are arranged on the openings. A groove 8 is provided at the central position of the bracket 3, and a first threaded shaft 9 is rotatably mounted up and down in the groove 8. The lower ends of the two first threaded shafts 9 are fixedly connected with first adjusting blocks 10; two horizontal plates 7 are slidably arranged on the surface of the bracket 3, and sliders 11 are fixedly arranged at the central positions of the two horizontal plates 7. The two grooves 8 respectively thread through the upper and lower sliders 11. The lower end of one end of each arc-shaped supporting piece 12 is fixedly connected with a connecting shaft 13, the lower end of the connecting shaft 13 is fixedly connected with a card 14, a corner is provided on the card 14, and the card 14 is clamped and fixed on the horizontal plate 7 through the corner. A rotating shaft 15 is rotatably mounted on the lower end of each card 14, one end of the rotating shaft 15 is fixedly connected with a scraping blade 25, and a cross groove 17 is provided at the other end of the rotating shaft 15; a water tank 4 is provided on each opening of the bracket 3, a water pipe 5 is fixedly installed in each water tank 4, a spray head 6 is rotatably installed on each opening, and each spray head 6 is communicated with the corresponding water pipe 5. The water pipe 5 is externally connected with a water tank, and the lower end of the spray head 6 faces one end of the arc-shaped supporting piece 12 close to the connecting shaft 13; fixing blocks 24 are fixedly installed at the upper and lower ends on one side of the bracket 3, and two second threaded shafts 21 are rotatably connected between the two fixing blocks 24. The two second threaded shafts 21 are connected up and down and are rotatably connected to each other. The lower end of one of the second threaded shafts 21 is fixedly installed with a second adjusting block 22, and the lower end of the other second threaded shaft 21 is fixedly connected with a third adjusting block 23. Moving blocks 20 are threadedly sleeved on the upper and lower second threaded shafts 21, motors 19 are fixedly installed on the two moving blocks 20, the driving ends of the two motors 19 are fixedly connected with a pushing roller 16, a plurality of rubber sheets are arranged around the surface of the pushing roller 16, and the cross section of the pushing roller 16 presents a star structure.

[0020] The plugging device for the screw holes of the external hanging scaffold of the present invention adjusts the distance between the upper and lower cross plates 7 according to the screw holes on the wall. The first adjusting block 10 can drive the first threaded shaft 9 to rotate. The first threaded shaft 9 threadedly passes through the slider 11. As the first threaded shaft 9 rotates, the slider 11 can be driven to move up and down in the groove 8, thereby driving the corresponding cross plate 7 to move and changing its height position. Then, according to the number of screw holes within the opening range, the corresponding number of arc-shaped supporting pieces 12 are selected for use. The arc-shaped supporting pieces 12 are clamped on the cross plate 7 through the connecting shaft 13 and the card 14. Thus, multiple arc-shaped supporting pieces 12 can be used as needed, and the arc-shaped supporting pieces 12 are arranged opposite to the screw holes on the outer wall.

[0021] Under the action of the water pump, the water tank sprays water through the water pipe 5 by the nozzle 6, thereby wetting the screw holes. Then, the precast concrete cones for sealing are placed on each arc-shaped supporting piece 12. The motor 19 is started. The plugging device for the screw holes of the external hanging scaffold of the present invention drives the rubber sheets on its surface to rotate with the rotation of the pushing roller 16. Under the pushing of each rubber sheet, the precast concrete cones are pushed into the corresponding screw holes. After the pushing is completed, the staff uses a rotating hand-held electric drill, inserts its driving end into the cross groove 17, and drives the scraping blade 25 at the other end to rotate through the rotating shaft 15, so as to clean and level the excess materials on the wall surface;

[0022] After plugging a batch of screw holes, the device is pushed through the installation hole 18 to plug the next batch of screw holes. The position of the pushing roller 16 can be adjusted up and down according to the position of the cross plate 7. The second adjusting block 22 drives the second threaded shaft 21 to rotate, so that the moving block 20 threaded through moves up and down, thereby changing the position of the pushing roller 16.

[0023] The above embodiments are only for illustrating the present invention, rather than limiting the present invention. Those skilled in the relevant technical fields can also make various transformations or changes without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by each claim.
