Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further explained with reference to the accompanying drawings and the detailed description.

Examples

As shown in fig. 1 to 3, in the turnout heel end limiting device, a steel rail 1 is fixedly mounted on a base plate 2 through a fastener 3, the base plate 2 is connected with a sleeper 5 through a spike bolt 4, a limiting column 6 is fixedly connected to the upper surface of the base plate 2, and a slot matched with the limiting column 6 is formed in the rail bottom of the steel rail 1; two stop blocks 7 are symmetrically arranged on the base plate 2, the steel rail 1 is arranged between the two stop blocks 7, the fasteners 3 are arranged on the stop blocks 7, and the two ends of the base plate 2 are symmetrically provided with the jacking mechanisms 8.

The tight mechanism 8 in top includes front bezel 9, back plate 10 and locking bolt 11, 2 one end fixedly connected with of backing plate 2 front bezel 9, fixed mounting has on backing plate 2 back plate 10, the equal threaded connection in both ends of front bezel 9 has locking bolt 11, one locking bolt 11 simultaneously with front bezel 9 with back plate 10 threaded connection, locking bolt 11's tail end top is tight rail 1.

The back plate 10 is located between the stopper 7 and the front plate 9.

A plurality of reinforcing plates 12 are arranged on the rear plate 10 and the front plate 9, and the reinforcing plates 12 are fixedly arranged on the backing plate 2.

Both ends of the front plate 9 and the rear plate 10 extend out of the backing plate 2.

In this embodiment, the fastening member 3 includes a fastening bolt screwed to the stopper 7 and an anti-jump spring tightly pressed against the stopper 7 by the fastening bolt, and one side of the anti-jump spring tightly presses the rail 1.

The working process and principle are as follows: the rail anti-bouncing device is characterized in that a tie plate 2 is fixedly installed on a sleeper 5 by using a spike bolt 4, a steel rail 1 is embedded between two stop blocks 7 of the tie plate 2, a slot at the rail bottom of the steel rail 1 is matched with a limiting column 6, a fastener 3 is installed on the stop blocks 7, an anti-bouncing spring presses the steel rail 1 to prevent the steel rail 1 from bouncing, a locking bolt 11 is installed on a front plate 9 and a rear plate 10, and the end part of the locking bolt 11 is closely focused on the rail web of the steel rail 1.
