Description

Technical Field

[0001] The utility model relates to the technical field of railway track equipment, in particular to a fixing structure for a curved railway track. Background Art

[0002] Steel mill molten iron trucks are specialized vehicles used to transport high-temperature molten iron (i.e., molten pig iron) in steel mills. During transportation, when heavy molten iron trucks negotiate curves, their bodies and wheels may be subject to lateral compressive forces, causing the trucks to move sideways. This friction is transmitted to the bolts and bushings securing the concrete sleepers. This compressive force can cause the bolts and bushings to deform or loosen, reducing the bolt's locking force.

[0003] Existing technologies for fixing bolt-to-cement concrete bushing connections in curved railway sections have several shortcomings. Damage and deformation of the bushings caused by prolonged stress remain common. Conventional repair methods include replacing the entire concrete sleeper, removing residual bushings, and securing the bolts with glue. However, these methods have limitations, and replacing the entire concrete is cumbersome and costly. Utility Model Content

The sleepers 5 are evenly distributed below the curved rail 1. The curved rail 1 is an I-shaped part. The curved rail 1 has an inner rail 13 and an outer rail 14.

After tightening the stop bolt 6, the fixing washer 11 is pressed downward by the limiting plate 12, causing the stop plate 8 to be pressed against the extrusion plate 7 and the lower rail 3, thereby securing the curved rail 1.

[0027] Furthermore, one end of the limiting plate 8 contacts and fits tightly with the outer side of the vertical iron 4. The thickness of the extrusion plate 7 is consistent with the thickness of the lower rail 3. The extrusion plate 7 contacts and fits tightly with the outer side of the lower rail 3.

[0028] Furthermore, the length of the connecting plate 9 is greater than the length of the sleeper 5 , and the width of the connecting plate 9 is greater than the width of the sleeper 5 .

[0029] Furthermore, two limit plates 8 are provided, one on the inside of the inner rail 13 and one on the outside of the outer rail 14. Two extrusion plates 7 are provided, one on the inside of the inner rail 13 and one on the outside of the outer rail 14.
