Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge maintenance, in particular to a road and bridge crack reinforcement structure. Background Art

[0002] Road bridge crack reinforcement structures are a type of structural design used to repair and reinforce cracks in road bridges. These structures are usually made of high-strength materials and are designed to prevent cracks from expanding further and enhance the structural stability and load-bearing capacity of the bridge. Common reinforcement structures include steel plates, carbon fiber sheets, prestressed concrete beams, etc.

[0003] Traditional road bridge crack reinforcement structures typically include steel plates, carbon fiber composites, injection materials, prestressed steel cables, concrete patches, and support and anchor systems. These components work together to enhance the structural stability and load-bearing capacity of the bridge, repair cracks and extend the service life of the bridge. The steel plates provide additional support, the carbon fiber composites enhance tensile strength, the injection materials fill cracks and prevent penetration, the prestressed steel cables strengthen bending capacity, the concrete patches repair damaged areas, and the support and anchor systems stabilize the bridge structure.

[0004] However, the fixing mechanism of the traditional road bridge crack reinforcement structure cannot be extended or retracted, which limits the operational flexibility when dealing with large or complex cracks. For workers, this difficulty is more significant, especially when the cracks are located at high or difficult-to-reach locations. In actual operations, additional safety measures are required or special tools and equipment are used to meet this challenge, which increases the complexity and risk of the operation. Due to the fixed nature of the reinforcement structure, more time and effort are required to adjust and adapt to the shapes and sizes of different cracks. Therefore, a road bridge crack reinforcement structure is proposed to solve the above problems. Utility Model Content

[0033] Specifically, when using the road bridge crack reinforcement structure, first fix the two rubber washers 1. Then, by turning the handle 3, drive the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the sliding plate 11 to move on the outer wall of the first fixed column 9. Then, the movement of the sliding plate 11 drives the first connecting rod 12 to move through the threaded rod 10, which then drives the roller 13 to rotate. The rotation of the roller 13 drives the second connecting rod 14 and the rotating column 15 to rotate synchronously. The rotation of the rotating column 15 further drives the sliding plate 11 to connect the support, thereby achieving the telescopic effect of the structure.

The movement of the fourth connecting rod 20 drives the rotating ring 21 to rotate, thereby driving the first connecting plate 8 to rotate. The rotation of the first connecting plate 8 affects the movement of the bottom support plate 23, so that the support plate 23 pushes the push plate 24 at the bottom to move on the road surface.

[0038] Working principle: When using the road bridge crack reinforcement structure, first fix two of the rubber washers 1, then rotate the rotating handle 3 to drive the threaded rod 10 on one side to rotate, and then the rotation of the threaded rod 10 drives the sliding plate 11 to move, and the sliding plate 11 slides on the outer wall of the first fixed column 9, and the sliding plate 11 is moved by the threaded rod 10, and the first connecting rod 12 is driven to move, and then the movement of the first connecting rod 12 drives the roller 13 to rotate, and the rotation of the roller 13 drives the second connecting rod 14 of the outer wall to rotate together, and the rotation of the second connecting rod 14 drives the rotating column 15 to rotate together, and the rotation of the rotating column 15 drives the sliding plate 11 to connect and support, achieving a retractable effect, and then press the rotating handle 6 to make The downward movement of the rotating handle 6 drives the fixed rod 16 to move downward together, and the fixed rod 16 is forced to drive the fixed plate 18 downward together. At the same time, the spring 17 arranged on the outer wall of the fixed rod 16 drives the fixed rod 16 to reset, so as to facilitate the next operation. The force of the fixed plate 18 drives the fourth connecting rod 20 and the third connecting rod 19 to move in two opposite directions. The movement of the fourth connecting rod 20 drives the rotating ring 21 to rotate, and the rotation of the rotating ring 21 drives the first connecting plate 8 to rotate. The rotation of the first connecting plate 8 drives the bottom support plate 23 to move together.
