Description

Technical Field

[0001] This utility model relates to the field of grouting equipment technology, specifically to a grouting equipment for repairing cracks in bridge abutments. Background Technology

[0002] In the field of bridge engineering, bridge abutments, as key components that bear the load of the superstructure and transfer it to the foundation, are subject to long-term effects such as vehicle dynamic loads, environmental erosion, and temperature changes, making them prone to cracking. Grouting is a common method for repairing cracks to ensure the safety of bridge structures. This technique involves injecting prepared grout into the cracks, filling the fissures, and allowing it to solidify, thereby restoring the integrity and load-bearing capacity of the abutment structure.

[0003] However, traditional equipment uses separate drive devices for grout mixing, crack cleaning, and grout delivery, which requires additional space and energy. After mixing, the grout must be transferred to the grouting equipment manually or by a transfer device, increasing the complexity and time cost of the construction process. In the crack cleaning stage, the separate cleaning equipment and the grouting equipment lack coordination, resulting in low construction efficiency. To address these issues, the inventors propose a bridge abutment crack repair grouting device to solve these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-4 As shown, this utility model provides a grouting device for repairing cracks in bridge abutments, including an installation plate 1. A container 2 is fixedly connected to the top of the installation plate 1. An agitator 3 is rotatably connected to the top of the inner wall of the container 2. A cleaner 4 is rotatably connected to one side of the bottom of the installation plate 1. A feeding cylinder 5 is fixedly connected to the bottom of the container 2. A spray pipe 8 communicating with the inside of the feeding cylinder 5 is fixedly connected to the end of the feeding cylinder 5 away from the cleaner 4. A spiral blade 6 is rotatably connected to one side of the inner wall of the feeding cylinder 5. The agitator 3, the cleaner 4, and the spiral blade 6 are connected by a transmission assembly 7.

[0018] The transmission assembly 7 includes a drive wheel 71. The top end of the agitator 3 shaft extends to the top end of the container 2 and is fixedly connected to the drive wheel 71. A rotating rod 72 is rotatably connected to one side of the container 2. A driven wheel 73 is fixedly connected to the top end of the rotating rod 72. The drive wheel 71 and the outer side of the driven wheel 73 are connected by a belt drive. A gear 74 is fixedly connected to the outer side of the bottom of the rotating rod 72. A rotating sleeve 75 is rotatably connected to the mounting plate 1. A gear 76 is fixedly connected to the outer side of the top of the rotating sleeve 75. The gear 76 meshes with the gear 74.

[0019] By adopting the above technical solution, when the agitator 3 rotates to agitate the slurry inside the container 2, it drives the drive wheel 71 to rotate. The drive wheel 71 and the driven wheel 73 are connected by a belt drive, which simultaneously drives the rotating rod 72 and gear 74 to rotate. Gear 74 meshes with gear 76, which in turn drives the cleaner 4 to rotate, thus achieving the cleaning operation of the gaps.

[0020] A bevel gear 77 is fixedly connected to the outside of the rotating rod 72 and above the gear 74. One end of the rotating shaft of the spiral blade 6 extends to the outside of the feeding cylinder 5 and is fixedly connected to a bevel gear 78. The bevel gear 77 and the bevel gear 78 are meshed together.

[0021] By adopting the above technical solution, when the rotating rod 72 rotates, it drives the bevel gear 77 to rotate. The bevel gear 77 meshes with the bevel gear 78, which in turn drives the spiral blade 6 to rotate, thereby realizing the directional conveying of the slurry inside the container cylinder 2.

[0022] A telescopic rod 9 is fixedly connected to the top center of the sweeper 4. The top of the telescopic rod 9 moves through the rotating sleeve 75. A key 10 is fixedly connected to the side of the telescopic rod 9. A key groove 11 is opened inside the rotating sleeve 75. The key 10 is slidably engaged in the key groove 11. An electric push rod 12 is fixedly installed on the top of the mounting plate 1 near the key groove 11. A connecting plate 13 is fixedly connected to the piston rod of the electric push rod 12. The top of the telescopic rod 9 is fixedly connected to the connecting plate 13.

[0023] By adopting the above technical solution, through the cooperation between key 10 and keyway 11, the telescopic rod 9 can move vertically while rotating with the rotating sleeve 75, and the distance between the sweeper 4 and the gap can be adjusted by the extension and retraction of the piston rod of the electric push rod 12.

[0024] Rollers 14 are rotatably connected to both sides of the mounting plate 1. A push handle 18 is fixedly connected to the top of the mounting plate 1 near the container cylinder 2. A reversing wheel 15 is rotatably connected to the bottom of the mounting plate 1 away from the rollers 14.

[0025] By adopting the above technical solution, the cooperation between the roller 14 and the push handle 18 facilitates better movement of the equipment, and by setting the reversing wheel 15, it is easier to change the direction of travel of the mounting plate 1.

[0026] An L-shaped plate 16 is fixedly connected to the top of the mounting plate 1, and a servo motor 17 is fixedly installed on the top of the L-shaped plate 16. The drive end of the servo motor 17 is fixedly connected to the stirrer 3.

[0027] By adopting the above technical solution and setting up a servo motor 17, the device can be driven.

[0028] The diameter of gear 1, 74, is larger than the diameter of gear 2, 76.

[0029] By adopting the above technical solution, and by setting the diameter of gear 1 74 to be larger than the diameter of gear 2 76, it is easier to control the transmission ratio between the rotating rod 72 and the sweeper 4, so that the equipment can operate more stably.

[0030] Working principle: When grouting the gaps in the bridge abutment, the servo motor 17 drives the agitator 3 to rotate, stirring the grout inside the container 2. At the same time, it drives the drive wheel 71 to rotate. The drive wheel 71 and the driven wheel 73 are connected by a belt drive, which drives the rotating rod 72 and gear 1 74 to rotate. Gear 1 74 meshes with gear 2 76, which in turn drives the cleaner 4 to rotate, thus cleaning the gaps.

[0031] At the same time, when the rotating rod 72 rotates, it drives the bevel gear 77 to rotate. The bevel gear 77 meshes with the bevel gear 78, which in turn drives the spiral blade 6 to rotate, thereby realizing the directional conveying of the slurry inside the container cylinder 2.

[0032] Furthermore, by utilizing the cooperation between key 10 and keyway 11, the telescopic rod 9 can move vertically while rotating with the rotating sleeve 75, and the distance between the sweeper 4 and the gap can be adjusted by extending and retracting the piston rod of the electric push rod 12.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
