[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a grouting device for high-safety concrete mortar, including a concrete pump truck, a concrete grouting component, a lifting regulator and an automatic annular adjusting mechanism. The concrete pump truck includes a pump truck body 1 and a manipulator 2 installed on the pump truck body 1. The concrete grouting component is installed on the concrete pump truck and includes a concrete storage container 3, a pump body 4, a feeding pipe 5 and a spraying pipe 6. The concrete storage container 3 is installed on the pump truck body 1. The pump body 4 is installed on the concrete storage container 3 and the discharge end is connected to the feeding pipe 5. The feeding pipe 5 is distributed and fixed along the manipulator 2. The end of the feeding pipe 5 is connected to the spraying pipe 6. The lifting regulator is installed at the outer end of the manipulator 2 and the lower end is connected to the automatic annular adjusting mechanism. The automatic annular adjusting mechanism includes an installation ring 7, a rotating ring 8, an adjusting component 9, a reel 10, a traction rope 11 and a collar 12. The installation ring 7 is fixed to the lower end of the lifting regulator. The rotating ring 8 is rotatably arranged inside the installation ring 7. The adjusting component 9 is installed between the installation ring 7 and the rotating ring 8. Several groups of reels 10 are evenly installed on the inner wall of the rotating ring 8. All several groups of reels 10 are connected to the collar 12 through the traction rope 11. The collar 12 is fixed to the spraying pipe 6. Several groups of cameras 13 are evenly installed at the bottom of the installation ring 7. The several groups of cameras 13 are annularly distributed and the shooting ends face the end of the spraying pipe 6.

[0022] Further improved, as Figure 1 shown: Several groups of annular stretching grooves 14 are formed in the middle of the spraying pipe 6. The several groups of annular stretching grooves 14 are distributed in a stacked manner, which is convenient for adjustment processing.

[0023] Further improved, as Figure 2 shown: The adjusting assembly 9 includes an annular cable 15, an electromagnetic block 16 and a magnet 17. The annular cable 15 is annularly distributed inside the mounting ring 7. Several groups of electromagnetic blocks 16 are provided and the upper ends are connected to the annular cable 15. Several groups of magnets 17 are provided and evenly installed on the outer side of the rotating ring 8. The electromagnetic block 16 is located on one side of the magnet 17. When it is necessary to finely adjust the position of the winder 10 to meet the adjustment of the more comprehensive position of the spray pipe 6, the electromagnetic block 16 can be energized. The electromagnetic block 16 generates magnetism in the energized state and acts on the magnet 17. The magnet 17 moves in the direction away from the electromagnetic block 16, thereby driving the rotating ring 8 and the winder 10 to rotate synchronously.

[0024] Further improved, as Figure 3 shown: The opposite surfaces of the electromagnetic block 16 and the magnet 17 have the same magnetic poles in the energized state.

[0025] Further improved, as Figure 4 shown: The winder 10 includes a housing 18, a drive motor 19, a winding rod 20 and a locking device 21. The housing 18 is fixed to the inner wall of the rotating ring 8. The drive motor 19 is installed on the top of the housing 18 and the power output end is connected to the winding rod 20. The winding rod 20 is placed inside the housing 18. A through hole 22 is formed on the surface of the housing 18. The towing rope 11 passes through the through hole 22 and is connected to the winding rod 20. The locking device 21 is installed outside the through hole 22. The drive motor 19 drives the winding rod 20 to rotate. The winding rod 20 realizes the winding and unwinding adjustment of the towing rope during the rotation process. When the towing rope is in the winding state, it can tow the spray pipe 6 to move and adjust to this place, otherwise it returns to the reset position and is fixed by the locking device 21.

[0026] Further improved, as Figure 4As shown: the locking device 21 includes a motor 23, a rotating wheel 24, a toggle block 25, an arc-shaped pressure rod 27, a pressure rod 28 and a clamping plate 29. The motor 23 is installed above the through-hole 22 and the power output end is connected to the rotating wheel 24. The toggle block 25 has an arc-shaped structure and is installed on the edge of the rotating wheel 24. The arc-shaped pressure rod 27 is located below the rotating wheel 24 and its two ends are respectively rotatably connected to two groups of pressure rods 28. A positioning plate 30 is rotatably inserted in the middle of the pressure rod 28. The positioning plate 30 is fixed to the housing 18. The pressure rod 28 The outer end is in conflict with the outer wall of the clamping plate 29, and the two groups of clamping plates 29 are symmetrically arranged on both sides of the through-opening 22. When the traction rope 11 is wound up, the rotating wheel 24 is driven to rotate by the motor 23. During the rotation, the rotating wheel 24 drives the toggle block 25 to rotate synchronously, and gradually conflicts with the arc-shaped pressure rod 27 and tends to straighten in an arc shape. The end of the arc-shaped pressure rod 27 moves outward to push the pressure rod 28 to rotate around the positioning plate 20, and makes the outer end conflict with the clamping plate 29. The two groups of clamping plates 29 clamp the traction rope 11.

[0027] Specifically, the lifting regulator includes a vertical rod 31, an electric push rod 32, a connecting column 33 and a guide rod 34. The upper end of the vertical rod 31 is connected to the robot arm 2, the electric push rod 32 is fixed to the lower end of the vertical rod 31 and the lower end is connected to the connecting column 33, the guide rod 34 is respectively fixed on both sides of the electric push rod 32, and the lower end of the guide rod 34 is movably inserted into the connecting column 33. The connecting column 33 is pushed by the electric push rod 32 for longitudinal adjustment, thereby achieving the purpose of adjusting the height of the lower end of the automatic annular adjustment mechanism and the spray pipe 6.

[0028] During use: When it is necessary to grout the steel frame of the building, the staff can drive the concrete pump truck to the outside of the building, and drive the mechanical arm 2 to move the spray pipe 6 to the top of the steel frame, and push the connecting column 33 through the electric push rod 32 for longitudinal adjustment as needed, so as to achieve the purpose of adjusting the height of the lower end of the automatic annular adjustment mechanism and the spray pipe 6. After the adjustment is completed, the concrete is pumped out through the pump body 4 and poured into the concrete frame. During the grouting process, the driver can make targeted position adjustments through the grouting position image obtained by the camera 13. When it is necessary to move the spray pipe 6 to a certain position, the reel 10 at that position can be controlled to work, and the reel rod 20 can be driven to rotate by the driving motor 19. The reel rod 20 realizes the retraction and release adjustment of the traction rope during the rotation. When the traction rope is in the retraction state, the reel 10 can be controlled to rotate. When the traction rope 11 is in the rolled state, the spray tube 6 can be pulled to move there for adjustment, and vice versa to reset. When the traction rope 11 is wound up, the motor 23 drives the rotating wheel 24 to rotate. During the rotation, the rotating wheel 24 drives the toggle block 25 to rotate synchronously, and gradually contacts the arc pressure rod 27 to straighten in an arc shape. The end of the arc pressure rod 27 moves outward to push the pressure rod 28 to rotate around the positioning plate 20, and makes the outer end contact the clamping plate 29. The two sets of clamping plates 29 clamp the traction rope 11. In addition, when it is necessary to fine-tune the position of the reel 10 to meet the more comprehensive position adjustment of the spray tube 6, the electromagnetic block 16 can be energized. The electromagnetic block 16 generates magnetism when energized and acts on the magnet 17. The magnet 17 moves in the direction of the principle electromagnetic block 16, thereby driving the rotating ring 8 and the reel 10 to rotate synchronously.
