When the gantry 10 moves to the left side of the mobile frame, the two vertical parts of the gantry 10 correspond to the two cleaning units on the right side.
[0043] Specifically, a cleaning unit is provided in the lower end of the first frame 7 and the lower end of the second frame 9. The cleaning unit comprises two mounting frames 17 symmetrically arranged on both sides, and sponge strips 43 are fixed on the opposite end surfaces of the two mounting frames 17.
[0044] The front and rear ends of the mounting frame 17 are respectively slidably disposed in the two sliding frames 18. Specifically, a third sliding block 44 is fixed on the mounting frame 17, and the third sliding block 44 is slidably disposed in the sliding frame 18.
[0045] A second groove 41 is formed on opposite end surfaces of the two mounting frames 17 . The third spring 42 is located in the second groove 41 . Two ends of the third spring 42 are fixedly connected to the two mounting frames 17 , respectively.
[0046] The sliding frame 18 is elastically slidably connected in the vertical direction of the mobile frame. Specifically, vertical fixed columns 20 are fixed in the first frame body 7 and the second frame body 9, and the fixed columns 20 penetrate the sliding frame 18.

[0047] Connecting columns 28 are fixed to both the front and rear ends of the mounting frame 17. Guide components are provided on the inner walls of the mobile frames on both the front and rear sides of the cleaning unit. Specifically, the guide components include an inverted triangular limiting groove 15, and the limiting groove 15 is provided on the front and rear inner walls of the first frame 7 and the second frame 9. Two left-right symmetrically arranged wedge blocks 21 are fixed in the upper part of the limiting groove 15, and the inclined surfaces of the two wedge blocks 21 are arranged opposite to each other. A fixed shaft 22 is fixed in the limiting groove 15 below the wedge block 21.

Specifically, a torsion spring is sleeved on the fixed shaft 22, one end of the torsion spring is fixedly connected to the fixed shaft 22, and the other end of the torsion spring is fixedly connected to the rotating plate 16.
[0049] The lower ends of the two rotating plates 16 are in contact with each other, and the connecting column 28 is located in the lower end of the limiting groove 15 on one side thereof. Each limiting groove 15 has two connecting columns 28 symmetrically arranged in the lower end.
[0050] The connecting assembly includes two second slide slots 29 provided on the movable frame, and the two second slide slots 29 are arranged left and right. The second slide slot 29 is provided at the lower end of the connecting rod 6, and the length direction of the second slide slot 29 is parallel to the length direction of the fourth slide slot 55, and the length of the second slide slot 29 is less than the length of the fourth slide slot 55.
[0051] The first slider 23 is slidably engaged in the second slide groove 29, and the left end of the left first slider 23 is fixed with a second magnet 36. The right end of the right first slider 23 is fixed with a second magnet 36. In the initial state, the second magnet 36 on the left first slider 23 is magnetically attracted to the first magnet 35 on the left side of the second slider 37.
[0052] The left and right ends of the moving frame are both provided with a third groove 121 and a first groove 12. Specifically, the third groove 121 is provided on the first frame body 7, and the first groove 12 is provided on the second frame body 9.
[0053] The seventh roller 24 is rotatably connected in the third groove 121 , one end of the first pull rope 13 is fixedly connected to the first slider 23 , and the other end of the first pull rope 13 is fixedly connected to the sliding frame 18 below the seventh roller 24 after passing around the seventh roller 24 .
[0054] A second roller 27 is rotatably connected in the first groove 12, a fixed seat 26 is fixed on the mobile frame outside the first groove 12, the fixed seat 26 is located below the first slider 23, and a first roller 25 is rotatably connected in the fixed seat 26. One end of the second pull rope 14 is fixedly connected to the lower end of the first slider 23, and the other end of the second pull rope 14 is fixedly connected to the sliding frame 18 below the second roller 27 after passing through the lower end of the first roller 25 and the upper end of the second roller 27 in sequence.
[0055] The magnetic attraction between the fifth magnet 51 and the sixth magnet 52 is smaller than the magnetic attraction between the third magnet 38 and the fourth magnet 39. The magnetic attraction between the fifth magnet 51 and the sixth magnet 52 is greater than the elastic force of the two fourth springs 50. The magnetic attraction between the first magnet 35 and the second magnet 36 is greater than the sum of the elastic forces of the third spring 42 and the first spring 19.
[0056] Start the second motor 11, the second motor 11 drives the second lead screw 31 to rotate, and the second lead screw 31 drives the second slider 37 to move to the right. Since the magnetic attraction between the fifth magnet 51 and the sixth magnet 52 is smaller than the magnetic attraction between the third magnet 38 and the fourth magnet 39. Therefore, during the movement of the second slider 37 to the right, the fifth magnet 51 and the sixth magnet 52 on the left are separated first. During the movement of the second slider 37 to the right, since the magnetic attraction between the first magnet 35 and the second magnet 36 is greater than the sum of the elastic forces of the third spring 42 and the first spring 19, the second slider 37 will drive the first slider 23 to move synchronously to the right. During the movement of the first slider 23 to the right, the first slider 23 causes the two cleaning units on the left to move upward through the first pull rope 13 and the second pull rope 14.
[0057] like Figure 7 , Fig.11 and Fig.12 As shown, when the cleaning unit moves upward, the first spring 19 is compressed. Under the guiding action of the two rotating plates 16 and the two wedge blocks 21 on the two connecting columns 28 in the limiting groove 15, the two mounting frames 17 and the two sponge strips 43 move away from each other during the upward movement of the cleaning unit, and the third spring 42 is stretched. When the two connecting columns 28 in the limiting groove 15 are located above the two wedge blocks 21, the two mounting frames 17 approach each other and restore under the pulling force of the third spring 42. At this time, the sponge strips 43 on the left and right sides of the vertical part of the door frame 10 contact the rectangular rod 49 and the sliding teeth 48. At the same time, the space between the two connecting columns 28 and the two wedge blocks 21 corresponds. When the second slider 37 is blocked by the right side wall of the fourth slide groove 55, the first magnet 35 on the left is separated from the second magnet 36 on the left. Then, under the elastic force of the first spring 19, the cleaning unit is restored downward, and the sponge strip 43 can scrape off the impurities on the rectangular rod 49 and the sliding teeth 48. The connecting column 28 in the limit groove 15 can drive the rotating plate 16 to rotate during the downward movement. After the rotating plate 16 rotates, the connecting column 28 can move into the lower end of the limit groove 15. After the connecting column 28 can move into the lower end of the limit groove 15, the two rotating plates 16 rotate and restore.
[0058] When the second slider 37 moves to the right, the second slider 37 moves the slide plates 54 and the sliding teeth 48 on the left and right sides through the third pull rope 40 and the fourth pull rope 45, that is, the sliding teeth 48 and the slide bar on the right side move upward, and the slide bar and the sliding teeth 48 on the left side move downward. The fourth spring 50 undergoes elastic deformation. When the fifth magnet 51 is adsorbed with the sixth magnet 52 on the right side, the lower end of the sliding tooth 48 on the right side is flush with the lower end of the rectangular rod 49 on the right side, and the lower end of the sliding tooth 48 on the left side protrudes to the lower end of the rectangular rod 49 on the left side. Since the magnetic attraction of the fifth magnet 51 and the sixth magnet 52 is greater than the elastic force of the two fourth springs 50. Therefore, the sliding teeth 48 on the left and right sides can maintain the current state.
[0059] When the fifth magnet 51 is attracted to the sixth magnet 52 on the right side, as the second slider 37 continues to move to the right, the third magnet 38 on the left side is separated from the fourth magnet 39 on the left side, and the door frame 10 moves to the right side along with the second slider 37. During the movement of the door frame 10 to the right, the rectangular rod 49 and the lower end of the sliding tooth 48 on the right side of the door frame 10 can flatten the upper end surface of the precast concrete component 3, and the lower end of the sliding tooth 48 on the left side of the door frame 10 can roughen the upper end surface of the precast concrete component 3.
[0060] When the door frame 10 moves to the right end of the mobile frame, Fig.13 As shown, the first magnet 35 on the right side of the second slider 37 is magnetically attracted to the second magnet 36 on the right side of the first slider 23. The third magnet 38 on the right side is magnetically attracted to the fourth magnet 39 on the right side.
[0061] The first lead screw 4 is driven by the first motor 8 , thereby causing the moving frame and the portal frame 10 to move one station along the length direction of the precast concrete component 3 .
[0062] Then the second motor 11 is started, the second motor 11 drives the second lead screw 31 to rotate, and the second lead screw 31 drives the second slider 37 to move to the left.
