[0027] Embodiment 1
[0028] Please refer to Figure 1-4 , a frame bridge jacking railway turnout area line reinforcement device, which is used in the field of railway reinforcement, including:
[0029] The reinforcing steel plate 1 is arranged on the outer side of the rail. The reinforcing steel plate 1 clamped by the clamping assembly helps to increase the bearing capacity and stability of the outer side of the rail, thereby solving the problem that the outer side of the rail is subjected to greater force when the train passes through the railway switch area;
[0030] The clamping assembly is arranged outside the reinforcing steel plate 1 and the rail, and is used to fix the reinforcing steel plate 1 and reinforce the rail. The clamping assembly includes two first clamps 2 arranged on the inner side of the rail and two second clamps 3 arranged on the outer side of the reinforcing steel plate 1. The partial side surfaces of the two groups of first clamps 2 and the second clamps 3 pass through the bottom of the rail and fit together. The inner side of the first clamp 2 is provided with a clamping groove 4 for clamping the inner bottom of the rail, so that the first clamp 2 is in contact with the bottom of the rail, and the inner side of the second clamp 3 is provided with a special-shaped groove 5 for clamping the outer bottom of the rail and the bottom of the reinforcing steel plate 1. When in use, the reinforcing steel plate 1 is placed in contact with the outer side of the rail, and then the two groups of first clamps 2 and second clamps 3 are placed at the two ends of the reinforcing steel plate 1 accordingly, so that the first clamp 2 clamps the inner bottom of the rail, and the second clamp 3 clamps the outer bottom of the rail and the bottom of the reinforcing steel plate 1, so as to prevent the first clamp 2 and the second clamp 3 from shaking after being locked;
[0031] The first clamp 2 and the second clamp 3 are both provided with a through hole 6, and the same threaded rod 7 passes through the two through holes 6. The threaded rod 7 is located under the rail, and both ends of the threaded rod 7 are fixed by threading with matching first nuts 8, and the radius of the first nut 8 is larger than the radius of the through hole 6. Then the threaded rod 7 is passed through the through holes 6 on the first clamp 2 and the second clamp 3, and the first nuts 8 are threadedly connected at both ends of the threaded rod 7 for reinforcement. The first clamp 2, the second clamp 3 and the reinforcement steel plate 1 are tightly fixed to the rail through the coordinated use of the threaded rod 7 and the first nut 8, which not only helps to improve the bearing capacity and stability of the rail, but also facilitates dismantling for subsequent inspection and replacement of the rail.
[0032] Embodiment 2
[0033] Improvements based on Example 1:
[0034] Please refer to Figure 1-2 and Figure 4 A gasket 9 is provided between the first clamp 2, the second clamp 3 and the corresponding first nut 8. The two gaskets 9 are sleeved on the threaded rod 7. The gasket 9 is preferably made of rubber. The provision of the gasket 9 made of rubber helps to increase the friction between the first clamp 2, the second clamp 3 and the corresponding first nut 8, thereby making the first nut 8 less likely to loosen.
[0035] Both ends of the threaded rod 7 are threadedly connected with a second nut 10, and the second nut 10 is tightly attached to the first nut 8. By screwing the two nuts, the fixing effect of the first clamp 2, the second clamp 3 and the reinforced steel plate 1 is improved, making the overall structure more solid.
[0036] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them.
