The setting of the collecting box 11 can facilitate the collection of waste generated during crack repair. At the same time, through the action of the buffer spring 15 and the connecting block 14, the collecting box 11 can be buffered and pushed, thereby maintaining the effect of contact with the wall.

[0056] In this embodiment, a movable groove 16 is opened on the front side of the mounting plate 4, and a threaded rod 17 is rotatably connected to the inner wall of the movable groove 16. The mounting block 5 is slidably connected to the inner wall of the movable groove 16, and the threaded rod 17 is threadedly connected to the mounting block 5. A first motor 18 is fixedly installed on one side of the mounting plate 4, and the output shaft of the first motor 18 is fixedly connected to the threaded rod 17. The output shaft of the first motor 18 drives the threaded rod 17 to rotate. The threaded rod 17 is threadedly connected to the mounting block 5, thereby driving the mounting block 5 to move, and then driving the glue injection gun 9 to move its position, so that the cracks in the wall can be automatically repaired and injected with glue.

[0057] In this embodiment, the stabilizing mechanism includes four inclined rods 38, which are slidably mounted on both sides of the fixed frame 37, and one end of each of the four inclined rods 38 is fixedly mounted with a fixed ring 39, and the load-bearing rope 36 is located in the fixed ring 39. The top of the fixed frame 37 is slidably connected to two moving rods 42, and the moving rods 42 are slidably connected to two movable blocks 43, and the movable blocks 43 are rotatably connected to the corresponding inclined rods 38, and the bottom of the moving rods 42 is fixedly mounted with a connecting seat 45, and the inner side of the fixed frame 37 is rotatably connected to a bidirectional screw 40, and the bidirectional screw 40 is A rotating block 41 is fixedly installed at one end, and the bidirectional screw 40 is threadedly connected to two connecting seats 45. The rotating rotating block 41 drives the bidirectional screw 40 to rotate. The bidirectional screw 40 is threadedly connected to the two connecting seats 45, thereby driving the two moving rods 42 to move in opposite directions. The moving rod 42 drives the inclined rod 38 to move through the movable block 43, thereby driving the four load-bearing ropes 36 to move away from each other, thereby increasing the angle between the load-bearing rope 36 and the hanging basket 1, and then making the force of the load-bearing rope 36 outward, so that the hanging basket 1 is more stable during hoisting.

[0058] Working principle: during operation, the worker hoists the person in the hanging basket 1 onto the high-altitude wall through the load-bearing rope 36, and detects the cracks in the wall through the ultrasonic detector 49. When repair is needed, the output shaft of the first motor 18 drives the threaded rod 17 to rotate, and the threaded rod 17 is connected with the mounting block 5 by a thread, so that the mounting block 5 can be driven to move, and then the glue injection gun 9 can be driven to move horizontally, so that the glue injection gun 9 can be aimed at the crack, and the first cylinder 6 switch is started. The piston of the first cylinder 6 drives the glue injection gun 9 on the fixed block 7 close to the crack, so that the glue injection box 2 automatically repairs the crack in the wall through the hose 10 and the glue injection gun 9. When the hanging basket 1 is moved up and down, the hanging basket 1 is supported by the rotating wheel 29, so that the hanging basket 1 can move and walk on the outside of the wall. The setting of the six fixed ribs 28 and the rotating wheel 29 can facilitate smooth movement when passing through the step position. At the same time, the moving push plate 33 drives the two push rods 34 to move, and the push rods 34 are connected with the support rods 26. The rotating connection can push the support rod 26 to move, thereby adjusting the support distance. The mounting seat 8 drives the scraper 21 to act on the wall through the top rod 20, and under the action of the top spring 22, the scraper 21 is in contact with the wall, so that the wall cracks can be scraped flat. The setting of the collecting box 11 can facilitate the collection of waste generated during crack repair. At the same time, through the action of the buffer spring 15 and the connecting block 14, the collecting box 11 can be buffered and pushed, thereby maintaining the effect of contact with the wall. When the hoisting height is high, the rotating block 41 is rotated, and the rotating rotating block 41 drives the bidirectional screw 40 to rotate. The bidirectional screw 40 is threadedly connected to the two connecting seats 45, thereby driving the two moving rods 42 to move in the opposite direction. The moving rod 42 drives the inclined rod 38 to move through the movable block 43, thereby driving the four load-bearing ropes 36 away from each other, thereby increasing the angle between the load-bearing rope 36 and the hanging basket 1, thereby making the force of the load-bearing rope 36 outward, thereby making the hanging basket 1 more stable during hoisting.

[0059] Embodiment 2

[0060] The difference between this embodiment and the first embodiment is that two positioning seats 46 are fixedly installed on both sides of the hanging basket 1, and bolts 47 are threadedly connected to the positioning seats 46. A lifting ring 48 is fixedly installed on the top of the bolt 47. The lifting ring 48 is connected to the corresponding load-bearing rope 36. The bolt 47 is threadedly connected to the positioning seat 46, so that the load-bearing rope 36 and the hanging basket 1 can be easily disassembled, and the angle of the hanging basket 1 can be slightly adjusted. All structures in this application can be selected according to the actual usage conditions. The accompanying drawings are all schematic structural diagrams, and the specific actual dimensions can be appropriately adjusted.
