DETAILED DESCRIPTION
[0020] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0021] like Figure 1-3 As shown, the utility model provides a technical solution: an automatic maintenance device for prefabricated beams, comprising a bracket body 1 and an outer rod 5, the outer side of the bracket body 1 penetrates and is fixedly connected with a reserved interface 2, the bottom end of the bracket body 1 is fixedly connected with a maintenance nozzle 3, the bottom end of the bracket body 1 is fixedly connected with an inner rod 4, the inner wall of the outer rod 5 penetrates and is rotatably connected with a rotating shaft 6, one end of the rotating shaft 6 located inside the outer rod 5 is fixedly connected with a gear 11, the outer surface of the inner rod 4 is fixedly connected with a rack 12, the rack 11 is meshed with the gear 12, the inner rod 4 is located inside the outer rod 5, and the movable block 9 is slidably connected to the inner wall of the movable groove 10, the outer surface of the end of the rotating shaft 6 located outside the outer rod 5 is provided with a fixed notch 7, the rotating shaft 6 is located inside the outer rod 5 A fixed turntable 8 is fixedly connected to the outer surface of one end of the outer side, a movable groove 10 is opened on the inner wall of the outer rod 5, a movable block 9 is fixedly connected to the outer surface of the inner rod 4, and a moving wheel 19 is fixedly connected to the bottom end of the bracket body 1. The staff rotates the handle 13, and the handle 13 rotates to drive the fixed turntable 8 to rotate, and the fixed turntable 8 rotates to drive the rotating shaft 6 to rotate, and the rotating shaft 6 rotates to drive the gear 11 to rotate, and the gear 11 rotates to drive the rack 12 to move up and down. When the rack 12 moves up and down, it drives the inner rod 4 to move up and down to the required height. When the inner rod 4 moves up and down, the movable block 9 moves inside the movable groove 10, and the movable groove 10 limits the movement of the movable block 9 to keep the inner rod 4 able to move vertically.
[0022] like Figure 4As shown, a fixed block 14 is fixed to the outer surface of the outer rod 5, and a rotating rod 15 is penetrated inside the fixed block 14 and rotatably connected thereto. A positive thread 16 is provided on the outer surface of one end of the rotating rod 15, and a negative thread 17 is provided on the outer surface of the other end of the rotating rod 15. The outer surfaces of the positive thread 16 and the negative thread 17 are penetrated and threadedly connected thereto by a fixed plug 18. The fixed plug 18 is located inside the fixed slot 7, and the cross-sectional dimension of the fixed plug 18 is the same as the cross-sectional dimension of the fixed slot 7. When the rotating rod 15 is rotated, the positive thread 16 and the negative thread 17 both start to rotate. At this time, the two fixed plugs 18 start to move in opposite or same directions. The fixed plug 18 is inserted into the fixed slot 7 to limit the rotating shaft 6.
[0023] Working principle: When in use, push the support body 1 to the prefabricated beam that needs to be maintained, and the moving wheel 19 rotates to drive the support body 1 to move. When the height of the support body 1 needs to be adjusted, the staff rotates the rotating rod 15. When the rotating rod 15 rotates, the positive thread 16 and the negative thread 17 both begin to rotate. At this time, the two fixed plugs 18 begin to move in opposite directions, and the fixed plugs 18 are separated from the inside of the fixed notch 7. The shaft 6 loses its limit, and the staff rotates the handle 13. The rotation of the handle 13 drives the fixed turntable 8 to rotate, and the rotation of the fixed turntable 8 drives the shaft 6 to rotate, and the shaft 6 rotates The gear 11 is driven to rotate, and the rotation of the gear 11 drives the rack 12 to move up and down. When the rack 12 moves up and down, it drives the inner rod 4 to move up and down to the required height. When the inner rod 4 moves up and down, the movable block 9 moves inside the movable groove 10, and the movable groove 10 limits the movement of the movable block 9. When the height of the bracket body 1 is appropriate, the maintenance nozzle 3 also reaches the appropriate height, and the rotating rod 15 is rotated in the opposite direction. The rotating rod 15 rotates the two fixed plug blocks 18 for relative movement. The fixed plug block 18 is inserted into the fixed groove 7 to limit the rotating shaft 6, thereby maintaining the height of the inner rod 4 without changing.
