RAIL SPIKE

摘要

The proposed rail spike comprises a main pin (1) with a head (2) which grasps the flange (3) of the rail and a stop pin (4) with a head (5). The main pin (1) on the rear side of the head (2) is provided with a longitudinal guide groove (6) which extends beyond the boundaries of the body in a straight line through the head (2) and in a curved line on the middle section of its length. The stop pin (4) in cross-section matches the dimensions of the longitudinal guide groove (6) in the main pin (1) and has a pointed end (7). In the operating position, the main pin (1) is securely fixed in the sleeper (9) by the stop pin (4) whose pointed end (7) is driven into the body of the sleeper (9) along the curved line of the longitudinal guide groove (6) and has the effect of creating a reliable anchoring which prevents it from being pulled out.
