[0022] It is worth mentioning that, through the cooperation of mounting bracket 1, elevating gear 7, fixed frame 15, clamping seat 17, fixed part 23, positioning assembly and quick -connection assembly structure, the spray head of injection device can be conveniently and quickly assembled and fixed, and the position angle thereof can be moved and adjusted, the operation convenience is improved, the spray head can uniformly and continuously and stably spray concrete, the high -speed rail box girder is reinforced, the tediousness and error of manual adjustment are reduced, and the uniformity and quality of injection reinforcement are effectively guaranteed.

[0023] Through the setting of mounting bracket 1, elevating gear 7, linear module 14 and hydraulic push rod 16 and other multistage adjusting mechanisms, the flexible and accurate positioning of injection nozzle 25 in three-dimensional space is realized, the accuracy of concrete injection of sprayer is further improved, and the uniformity of concrete injection is guaranteed.The transmission rod 3 driven by the lifting motor 2 can control the height of the spray head, the linear module 14 adjusts the horizontal position, the hydraulic push rod 16 adjusts the injection angle, greatly improves the automation degree and operation precision of reinforcement construction, reduces the tediousness and error of manual adjustment, and effectively guarantees the uniformity and quality of injection reinforcement.

[0024] The positioning assembly comprises: a mounting baffle 10 movably installed in the inside of the elevating gear 7, and a clamping plate 11 connected to the surface of the mounting baffle 10; wherein the inside of the elevating gear 7 is embedded with an electromagnet 9 matched with the clamping plate 11, the outside of the clamping plate 11 is provided with a magnet block 12 matched with the electromagnet 9, and the inside of the elevating gear 7 is provided with a return spring 13 on one side of the mounting baffle 10.

[0025] Specifically, the lifting frame 7 is connected to the linear module 14, thereby driving the clamping seat 17 to lift, and the lifting frame 7 can further improve the stability of the adjustment of the spraying nozzle 25, facilitating the spraying nozzle 25 to spray and reinforce the concrete at different heights. The clamping plate 11 cooperates with the anti-loosening spring 5 to improve the stability of the lifting frame 7 on the transmission rod 3 and improve the safety of the working state of the lifting frame 7. The electromagnet 9 is electrically connected to the lifting motor 2. The lifting motor 2, the transmission rod 3, and the limiting rod 4 are used to support and adjust the height of the installed spraying nozzle 25. When the lifting motor 2 is driven, it is energized to generate a magnetic force opposite to the magnet block 12, forming a repulsive force that pushes the clamping plate 11 back to release the clamping effect. The installation baffle 10 cooperates with the return spring 13 to achieve self-locking when the lifting frame 7 is positioned. The positioning assembly is used to lock and fix the supporting height of the adjusted spraying nozzle 25, improving the supporting effect of the structure on the spraying nozzle 25.

[0026] The installation baffle 10, the clamping plate 11, the electromagnet 9, the magnet block 12, and the return spring 13 of the positioning assembly cooperate with the limiting rod 4 and the anti-loosening spring 5 to provide double positioning and buffering for the lifting frame 7.

The anti-loosening spring 5 continuously provides protection against falling, enhancing the safety of high-altitude work, preventing position slipping due to accidental loss of force, and ensuring smooth and controllable construction process.

[0027] The limiting rod 4 is symmetrically installed inside the mounting frame 1. One end of the clamping plate 11 is movably connected to the surface of the limiting rod 4. The limiting rod 4 has the anti-loosening spring 5 sleeved on its surface. The top end of the anti-loosening spring 5 is connected to the bottom of the lifting frame 7. The limiting guide rails 6 are connected to the inner walls of the mounting frame 1. The limiting guide grooves 8 are formed at both ends of the lifting frame 7 to slidably cooperate with the limiting guide rails 6. The lifting motor 2 is embedded inside the mounting frame 1 and connected to the transmission rod 3.

[0028] In addition, the mounting frame 1 installed on the spraying machine can facilitate the assembly of the spraying nozzle 25 and maintain the bearing position of the spraying nozzle 25. The limiting guide rails 6 and the limiting guide grooves 8 serve as guiding and limiting during the lifting process. The limiting rod 4 serves as guiding and limiting during the lifting of the lifting frame 7. The anti-loosening spring 5 acts on the lifting frame 7, effectively reducing the occurrence of the lifting frame 7 falling. The lifting motor 2 can be installed with a motor having a self-locking function, further improving the stability and safety of the structure.

[0029] The limiting guide rail 6 arranged in the mounting frame 1 is in sliding fit with the limiting guide groove on the lifting frame 7, guiding the lifting track, effectively resisting lateral force and torsion, enhancing the overall rigidity and vibration resistance of the structure. This design ensures smooth operation of the spray head during operation and movement, reduces shaking, and provides a solid mechanical foundation for continuous high-quality spraying construction.

[0030] The quick connection assembly comprises a connecting sleeve 19 connected to the bottom of the inner surface of the clamping seat 17, and a connecting baffle 21 movably mounted on the inner wall of the connecting sleeve 19. The surface of the connecting baffle 21 is connected with a positioning clamping column 20, and the inside of the connecting sleeve 19 is provided with a compression spring 22.

[0031] The clamping seat 17 is a structure for assembling the fixed part 23 and plays a role in angle adjustment of the spraying nozzle 25. The connecting baffle 21 is a structure for limiting and preventing the positioning clamping column 20 from falling off. The compression spring 22 acts on the connecting baffle 21 to clamp the positioning clamping column 20 in the positioning hole at the bottom of the quick mounting seat 24, realizing the quick mounting and positioning of the spraying nozzle 25. The positioning clamping column 20 cooperates with the compression spring 22 to keep the spraying nozzle 25 for spraying concrete reinforcement in a stable position.

[0032] One end of the compression spring 22 is connected to the inner surface of the positioning clamping column 20, and the end of the positioning clamping column 20 is movably inserted into the surface of the quick mounting seat 24. The surface of the clamping seat 17 is provided with a quick mounting slot 18, the quick mounting seat 24 is fixedly connected to the surface of the fixed part 23, and the quick mounting seat 24 is movably inserted into the inside of the quick mounting slot 18.

[0033] Further, the quick mounting slot 18 is a structure for cooperating with the quick mounting seat 24 for clamping, facilitating the quick mounting of the spraying nozzle 25. The hydraulic push rod 16 is movably mounted at the bottom of the fixed frame 15, and the extending end of the hydraulic push rod 16 is movably connected to the outer surface of the clamping seat 17. The surface of the spraying nozzle 25 is provided with the fixed part 23, facilitating the quick clamping of the spraying nozzle 25 on the clamping seat 17. The spraying nozzle 25 is externally connected with a spraying device for spraying concrete reinforcement of a high-speed railway box girder through a pipeline. The fixed frame 15 is a mounting structure for bearing the spraying nozzle 25, cooperating with the hydraulic push rod 16 to facilitate the angle adjustment and control of the mounted spraying nozzle 25. The clamping seat 17 is a connecting structure for supporting the spraying nozzle 25 in cooperation with the fixed part 23.

[0034] The quick mounting seat 24 cooperates with the quick mounting slot 18, and the quick connection assembly composed of the connecting sleeve 19, the positioning clamping column 20 and the compression spring 22 realizes the quick insertion and mechanical self-locking of the spraying nozzle 25. The operation of mounting and dismounting is simple, the locking is firm and reliable, the loosening or falling off of the nozzle caused by vibration during construction is avoided, and the stability and working efficiency of continuous operation of the equipment are significantly improved.

[0035] The spray nozzle 25 is quickly mounted into the quick-release slot 18 on the mounting base 17 via the quick-release bracket 24 on the surface of the fixing part 23. At this time, the compression spring 22 inside the connecting sleeve 19 acts on the connecting baffle 21, causing the positioning pin 20 to be locked at the bottom of the quick-release bracket 24, thus locking the position of the spray nozzle 25. Similarly, when disassembling, the positioning pin 20 is pushed back, and the quick-release bracket 24 can be pulled back with the spray nozzle 25 for disassembly.

[0036] During spraying, the linear module 14 can move and adjust the fixed frame 15, thereby driving the mounting base 17 to move and adjust its position. The hydraulic push rod 16 extends and pushes the bottom of the mounting base 17 to retract, so that the mounting base 17 moves around the fixed axis, which can adjust the angle of the installed spray nozzle 25.

[0037] The height of the connected lifting frame 7 is adjusted by driving the transmission rod 3 through the lifting motor 2. When the lifting motor 2 is driven, the electromagnet 9 is energized, generating a magnetic force opposite to that of the magnet block 12, forming a repulsive force, which releases the clamping effect of the clamping plate 11 on the limiting rod 4. After the adjustment is completed, the electromagnet 9 is de-energized, and the force of the return spring 13 on the mounting baffle 10 will clamp the clamping plate 11 onto the surface of the limiting rod 4, forming a self-locking effect.

[0038] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
