Description
Technical Field
[0001] This utility model relates to the field of railway bridge technology, and in particular to a railway bridge connection and fastening component that is easy to install. Background Technology
[0002] Railway bridge connection and fastening components are a series of parts used in the construction and maintenance of railway bridges to firmly connect various bridge components (such as beams, piers, and ancillary facilities). These components need to have sufficient strength and stability to withstand various external forces such as dynamic loads generated by train movement, wind loads in the natural environment, and expansion and contraction forces caused by temperature changes.
[0003] Existing fasteners for railway bridges are mostly mechanically fixed, which is not very effective in preventing breakage. They cannot be tightened instantly and require manual inspection of components for aging or rust, which is time-consuming and labor-intensive. Furthermore, workers need to repeatedly check the installation and installation to ensure that it is secure during operation, which is too cumbersome and cannot meet people's needs.
[0004] An existing patent (publication number: CN213740566U) discloses a fracture-resistant pneumatic fastener for railway bridges, including a support column, an air tank, and a housing. An air supply pipe is located on the left side of the housing, and an air valve is located below the air supply pipe. A fixing bracket is installed at the front end of the air tank via screws, and a pressure knob is located on the left side of the air tank. In this fracture-resistant pneumatic fastener for railway bridges, the air valve forms a rotating structure through the air supply pipe, and the air valve and air supply pipe are connected by a spiral, allowing for real-time control of the air volume and emergency braking. It is also convenient for easy disassembly and replacement. A baffle forms a sliding structure through the housing, and a baffle is fitted inside the housing. The baffle, forming a sliding structure, drives the movement of the upper support column, achieving precise control. The baffle also ensures good sealing inside the housing.
[0005] To address the aforementioned issues, existing patents offer solutions. However, the installation process of existing railway bridge connection and fastening components is often quite complex, making it difficult to quickly and accurately align the beams, resulting in low construction efficiency. Furthermore, the lack of effective basic connection structures to enhance the integrity and durability of beam connections makes it difficult to reliably guarantee the safety of the bridge structure during long-term use.
[0006] Therefore, a railway bridge connection fastening component that is easy to install is proposed. Utility Model Content

[0009] The pre-assembly mechanism includes a pre-assembly block, a connecting block, and a reinforcing bolt. The pre-assembly block is fixedly connected to the first beam on the side closest to the first beam. The left side of the connecting block is bolted to the right side of the pre-assembly block. The surface of the reinforcing bolt is fixedly connected to the inner wall of the connecting block.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:
[0028] An easy-to-install railway bridge connection fastening assembly includes a first beam 1, a second beam 3 disposed on the right side of the first beam 1, a pre-installation mechanism 2 bolted to the front and rear sides of the first beam 1, a pre-installation frame 4 bolted to the front and rear sides of the second beam 3, the surface of the pre-installation mechanism 2 being movably connected to the inner wall of the pre-installation frame 4, a pre-embedded rib 5 disposed on the inner wall of the first beam 1, and a pre-embedded base 6 disposed on the inner wall of the second beam 3;
[0029] The pre-assembly mechanism 2 includes a pre-assembly block 201, a connecting block 202, and a reinforcing bolt 203. The pre-assembly block 201 is fixedly connected to the first beam 1 on the side closest to the first beam 1. The left side of the connecting block 202 is bolted to the right side of the pre-assembly block 201. The surface of the reinforcing bolt 203 is fixedly connected to the inner wall of the connecting block 202. The surface of the connecting block 202 is movably connected to the inner wall of the pre-assembly frame 4.
[0030] In this embodiment: by setting up the pre-installation mechanism 2 and the pre-installation frame 4, the first beam 1 and the second beam 3 can be quickly aligned during installation through their movable connection, which facilitates construction operations and improves installation efficiency. The reinforcing bolts 203 enhance the tightness of the connection, effectively bearing the load generated during the operation of the railway bridge, ensuring the stability and reliability of the connection between the first beam 1 and the second beam 3, and reducing safety hazards caused by loose connections. By setting up the embedded reinforcement 5 and the embedded base 6, the embedded reinforcement 5 on the inner wall of the first beam 1 and the embedded base 6 on the inner wall of the second beam 3 provide a foundation for further reinforcement connections, increasing the integrity and durability of the connection between the first beam 1 and the second beam 3, meeting the needs of long-term use of railway bridges, and also helping to distribute and transfer loads, thereby improving the safety of the bridge structure.
[0031] Specifically, such as Figure 5 As shown, the inner wall of the pre-embedded base 6 is threaded with a knob 7, which is movably connected to the pre-embedded rib 5.
[0032] Specifically, such as Figure 5 As shown, a gasket 8 is provided on the top of the embedded rib 5, and the surface of the knob 7 is movably connected to the inner wall of the gasket 8.

The inner wall of the nut 10 is threadedly connected to the surface of the reinforcing bolt 203.
[0034] In this embodiment: the pre-embedded base 6 is movably connected to the pre-embedded reinforcement 5 through the knob 7. The knob 7, together with the washer 8, can fasten the pre-embedded reinforcement 5, which enhances the stability of the connection foundation between the first beam 1 and the second beam 3. The positioning block 9 on the inner wall of the pre-assembly frame 4 cooperates with the nut 10 to position and fasten the reinforcing bolt 203, which further improves the reliability of the connection between the pre-assembly mechanism 2 and the pre-assembly frame 4, ensuring that the connection part can stably bear various loads when the railway bridge is in operation.
[0035] Specifically, such as Figure 3 As shown, a limiting block 11 is bolted to the right side of the positioning block 9, and the surface of the limiting block 11 is movably connected to the inner wall of the pre-assembly frame 4.

[0037] In this embodiment: the positions of the limiting block 11 and the positioning block 9 are fixed to enhance the positioning effect of the positioning block 9 and prevent the positioning block 9 from shifting arbitrarily during use. The pre-installation groove 12 opened on the inner wall of the pre-installation frame 4 facilitates the movement of the connecting block 202 on the inner wall of the pre-installation frame 4 through the pre-installation groove 12. The installation groove 13 opened on the inner wall of the pre-installation frame 4 facilitates the movement of the reinforcing bolt 203 on the inner wall of the pre-installation frame 4 through the installation groove 13, making the connection between the first beam 1 and the second beam 3 more stable and improving the stability of the overall structure.

[0039] Specifically, such as Figure 3 As shown, a guide block 16 is bolted to the right side of the connecting block 202, and the surface of the guide block 16 is movably connected to the inner wall of the pre-assembly frame 4.
[0040] In this embodiment: the limiting groove 14 opened in the inner wall of the pre-assembly frame 4 facilitates the movable installation of the limiting block 11 in the inner wall of the pre-assembly frame 4 through the limiting groove 14; the countersunk hole 15 opened in the inner wall of the positioning block 9 facilitates the subsequent stable installation of the nut 10; the guide block 16 on the right side of the connecting block 202 can slide in the inner wall of the pre-assembly frame 4, playing a guiding role in the installation process, facilitating the smooth insertion of the pre-assembly mechanism 2 into the pre-assembly frame 4, and improving the convenience and accuracy of the installation.
[0041] Working principle: During the use of the first beam 1, the pre-installation mechanism 2 and pre-installation frame 4 enable the first beam 1 and the second beam 3 to be quickly aligned during installation through their movable connection, facilitating construction operations and improving installation efficiency. The reinforcing bolts 203 enhance the tightness of the connection, effectively bearing the load generated during the operation of the railway bridge, ensuring the stability and reliability of the connection between the first beam 1 and the second beam 3, and reducing safety hazards caused by loose connections. By setting the embedded reinforcement bars 5 and embedded bases 6, the embedded reinforcement bars 5 on the inner wall of the first beam 1 and the embedded bases 6 on the inner wall of the second beam 3 provide a foundation for further reinforcement connections, increasing the integrity and durability of the connection between the first beam 1 and the second beam 3, meeting the needs of long-term use of railway bridges, and also helping to distribute and transfer loads, improving the safety of the bridge structure.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
