[0002] In order to ensure the safe operation of vehicles, rail supports are installed on curves to protect the rails, prevent them from turning over, and ensure driving safety.

[0003] For example, patent CN 203346738 U discloses a heavy-duty rail support for curves. The support plates are extended at both ends to be flush with the side panels and bottom plate pads, increasing structural strength and reducing the camber of the rails in curved sections of railways by about one-third. The heavy-duty rail supports for curves are spaced 80-150mm apart, with a track gauge adjustment range of -4 to +8mm, greatly enhancing the stability of the line.

Rail height, in particular, requires frequent raising, and these raised rails require rail supports at the waist to ensure line safety. Current rail supports are unable to accommodate the large-scale height adjustments required, necessitating the development of a freely adjustable support suitable for small-radius mountainous lines.

[0038] In the curved rail support assembly provided by the present invention, the position of the rail support 3 on the mounting arm 1 can be adjusted according to the terrain requirements, so that the height of the rail support 3 meets the actual needs. Then, according to the size of the adjustment gap 3a between the rail support 3 and the sleeper 2, the corresponding number and thickness of adjustment shims 4 are placed, and the rail support 3 is supported at a preset height position by the adjustment shims 4. Then, the rail support 3 with the adjusted height is pressed against the adjustment shims 4 by the pressing portion 5, and the movement of the rail support 3 is restricted, so that the rail support 3 can stably support the rail 6. In this way, the height of the rail support 3 can be flexibly adjusted according to actual needs, and the rail support 3 can be ensured to stably support the rail 6, which has good practicality.

[0039] In one embodiment, see Figure 4The mounting arm 1 is a mounting screw 11, and the rail support 3 is provided with a mounting hole 3b for the mounting screw 11 to pass through; the pressing portion 5 includes a pressing nut 51, which is screwed on the mounting screw 11 and is located on the side of the mounting hole 3b away from the adjusting gasket 4.
