Guard rail silent joint safety device for high-speed train
The invention discloses a guard rail silent joint method. After a guard rail is mounted, a pulley runs under a track of a branch rail (1) of the guard rail without noises; and it means that the pulley runs under the track of the branch rail (1) of the guard rail like running on the track without a joint. The track of the branch rail of the guard rail is vertically divided into two parts; a part, with the length of 3 cm, is removed from one part and the half part of the middle part of a guard rail main body is also removed so as to form a concave shape (2); the next section of the guard rail is made into a convex shape (3); and after the guard rails are connected with each other, an expansion joint (4) is formed; therefore, the pulley cannot roll into the expansion joint (4) during running under the branch rail of the guard rail so that no noise can be generated. The guard rail silent joint method disclosed by the invention is advantaged in that defects of the prior art are overcome, lives and properties of passengers are guaranteed, and time is also saved.
