Embodiment Construction

[0043] Such as figure 1 Shown: A sleeper manufactured in accordance with the principles of the present invention is shown generally at 1 and supports substantially mutually parallel railway rails 2 in a manner well known to those skilled in the art.

[0044] The sleeper 1 includes an outer shell shown by number 3, which is formed as a whole, and its surroundings are integrally covered on the inner core 4. During the manufacturing process, the outer shell 3 is welded and attached to the inner core 4 to form a whole, so There is no gap between the shell 3 and the inner core 4 . In this embodiment, the thickness of the shell 3 is 25.4 mm, and different thicknesses can also be selected according to needs.

[0045] The support area of ​​the rail 2 is formed on the backing plate 5 on the surface of the shell 3, the backing plate 5 is fixed on the sleeper 1 by the fastener 6, the traditional spike 7 passes through the hole in the backing plate 5 and is nailed into the railway sleep...

Abstract

The invention provided an integral coving rail bearing which include belly core and the cover. The cover is made of deformable compound material. It is fused to the core to form a integral body, so the life and the reliability of it has improved greatly and the cost of service has decreased.

Description

technical field [0001] The invention relates to a railway sleeper and a manufacturing method thereof. Background technique [0002] In the early days of railways, railway sleepers were all made of wood. The wooden ties are held in place by ballast stones, while the steel rails are attached to the ties with backing plates and large square nails. [0003] Due to the nature of the wooden sleeper material, it can accept and hold the spikes, so that the rail and backing plate securing system can be fixed to the sleeper, which is its main advantage. Wooden sleepers bend under load. The advantage of this curvature is that it helps provide a softer ride. More disadvantageously, wooden sleepers are susceptible to sun exposure and wind and rain erosion, and deteriorate and age, and have a short service life, so they must be replaced regularly, which further increases the cost of replacement and maintenance. Especially because forest resources are becoming increasingly scarce, it i...
