发明名称 Boltless guardrail assembly for a railroad track
摘要 A railroad track is provided having a running rail and a guardrail which are spaced apart by self-locking separator blocks and mounted to base plates. The foot of the running rail fits within channels formed into each of the base plates, with an outward end of the foot secured within the channels by toe plates and an inward end of the foot secured within the channels by inward quick release fasteners. The guardrail is mounted atop the toe plates, outward from the running rail. Side brace plates and outward quick release fasteners are used to hold the guardrail against the separator blocks and on top of the toe plates. Vertical holes are formed into the foot of the guardrail, inward of the guardrail web and in the toe plate. The separator blocks each have a block extension which protrudes downward from the separator blocks through a respective one of the vertical holes in the guardrail foot and into one of the holes in the toe plate. The inward end of the separator blocks fit flush against the web of the running rail and directly underneath the running rail head. An outward end of the separator blocks fit flush against at least part of the web of the guardrail and along the top of the inward side of the foot of the guardrail. The separator blocks are secured between the guardrail and the running rail by the block extensions and web fit between the guardrail and the running rail.
