Description

Technical Field

[0001] The present application relates to the field of grouting technology, and more specifically, to a grouting device for highway bridge construction. Background Art

[0002] The grouting device for highway bridge construction is a device used in the process of highway bridge construction. It is used to inject slurry into designated parts of the bridge structure, such as gaps and holes in piers, abutments or bridge decks. It can effectively fill these spaces and enhance the stability and integrity of the structure. It mainly includes grouting pumps, grouting pipes and slurry storage containers, and each part cooperates with each other to complete the grouting work.

[0003] The nozzle position of traditional grouting equipment is difficult to adjust. When grouting at different locations, the equipment often needs to be frequently moved and adjusted, which not only consumes a lot of construction time but also makes flexibility and accuracy difficult to guarantee. Furthermore, during the grouting process, the mortar delivery efficiency is low. Due to the viscous resistance of mortar, conventional delivery methods cannot ensure continuous and uniform delivery. This results in slow grouting speed and inability to fully guarantee grouting density, which in turn affects the stability and durability of the engineering structure.

[0004] In view of this, the present application proposes a grouting device for highway bridge construction. Utility Model Content

The threaded conveying blade 13 utilizes the propulsion force of the spiral structure to efficiently grout, overcome the viscosity resistance of the mortar, make the mortar move forward continuously and at a uniform speed, improve the grouting speed, ensure the density, and enhance the stability and durability of the engineering structure.

[0022] A second electric telescopic rod 14 is fixedly connected to one end of the rotating rod 12. The second electric telescopic rod 14 passes through the fixed frame 11 and is rotatably connected to the fixed frame 11. The telescopic end of the second electric telescopic rod 14 is rotatably connected to the fixed pipe 4. When the nozzle position needs to be adjusted, the second electric telescopic rod 14 can respond quickly, driving the extension pipe 10 to move flexibly to adapt to different grouting points, reducing the number of equipment handling and adjustments, improving flexibility and accuracy, and saving construction time.

[0023] The interior of the connecting pipe 5 is fixedly connected to a support frame 6, and the upper part of the interior of the mortar barrel 1 is rotatably connected to a rotating shaft 7, and the lower end of the rotating shaft 7 passes through the support frame 6. The outer wall of the rotating shaft 7 is fixedly connected to a stirring blade 8, and the lower end of the rotating shaft 7 is fixedly connected to a first electric telescopic rod 9. The stirring blade 8 rotates to make the mortar composition stable and the texture uniform. It has good fluidity during subsequent grouting and can pass through the conveying pipeline smoothly to avoid blockage, thereby ensuring consistent mortar performance at the injection site, reducing construction defects such as grouting voids and uneven strength, and improving project quality.

[0024] A sealing box 15 is fixedly connected to one side of the interior of the fixed tube 4, and a first bevel gear 16 is rotatably connected to one side of the interior of the sealing box 15. A second bevel gear 17 is meshed above the first bevel gear 16. The telescopic end of the first electric telescopic rod 9 extends into the sealing box 15 and is fixedly connected to the second bevel gear 17. The telescopic end of the second electric telescopic rod 14 passes through the sealing box 15 and the first bevel gear 16 in sequence and is fixedly connected to the first bevel gear 16. The sealing box 15 protects the first bevel gear 16 and the second bevel gear 17, so that the mortar cannot enter the first bevel gear 16 and the second bevel gear 17 to avoid damage. The gear transmission grouting starting mechanism composed of the first electric telescopic rod 9, the first bevel gear 16 and the second bevel gear 17 is easy to operate, and the engagement is electrically controlled to reduce labor intensity and improve construction efficiency. The precise gear engagement ensures stable rotation transmission, laying the foundation for continuous and stable grouting operations and reducing the risk of interruption.

[0025] An injection port 2 is provided on one side of the upper end surface of the mortar barrel 1. A motor 3 is fixedly connected to the upper end surface of the mortar barrel 1. The output end of the motor 3 is fixedly connected to the rotating shaft 7. A limiting groove 19 is symmetrically provided on the inner wall of the fixed tube 4. A limiting strip 18 is symmetrically fixedly connected to the outer wall of the extension tube 10. The limiting strip 18 is located in the limiting groove 19, which plays a good limiting role, making the extension tube 10 more stable when moving.

[0026] Working Principle: During use, the worker injects mortar into the mortar barrel 1 through the injection port 2, moves the mortar barrel 1 to the designated position, and aligns one end of the extension tube 10 inside the fixed tube 4 with the location where grouting is required. First, start the motor 3, which drives the output end to rotate. The output end rotation drives the rotating shaft 7 and the stirring blade 8 to rotate synchronously. The stirring blade 8 rotates to fully and evenly mix the mortar.

[0027] During grouting, the first electric telescopic rod 9 is started first. The telescopic end of the first electric telescopic rod 9 moves to drive the second bevel gear 17 inside the sealing box 15 to move toward the first bevel gear 16 until the first bevel gear 16 is engaged with the second bevel gear 17. The rotation of the rotating shaft 7 drives the first electric telescopic rod 9 and the second bevel gear 17 to rotate synchronously. The rotation of the second bevel gear 17 drives the first bevel gear 16 and the telescopic end of the second electric telescopic rod 14 to rotate synchronously. The rotation of the telescopic end of the second electric telescopic rod 14 drives the second electric telescopic rod 14, the rotating rod 12 and the threaded conveying leaf 13 to rotate synchronously. The mortar then passes through the connecting pipe 5 and the support frame 6 and enters the fixed pipe 4. The mortar then passes through the sealing box 15 and the fixed frame 11 and enters the extension pipe 10. The sealing box 15 wraps the first bevel gear 16 and the second bevel gear 17 to protect the first bevel gear 16 and the second bevel gear 17, so that the mortar cannot enter the first bevel gear 16 and the second bevel gear 17 to avoid damage. The mortar then passes through the fixed frame 11 and enters the extension pipe 10. The threaded conveying blade 13 rotates to convey the mortar out of the extension pipe 10, thereby completing the grouting at the construction site.

[0028] When it is necessary to adjust the position of the nozzle of the extension tube 10, the staff starts the second electric telescopic rod 14, and the telescopic end of the second electric telescopic rod 14 is extended, thereby driving the fixed end of the second electric telescopic rod 14, the rotating rod 12 and the extension tube 10 to move, and the limiting strip 18 on the outer wall of the extension tube 10 slides in the limiting groove 19 on the inner wall of the fixed tube 4, and the nozzle end of the extension tube 10 extends out of the fixed tube 4 until the nozzle end moves to the specified position. After the grouting is completed, all electrical appliances are turned off.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
