Abstract

The invention discloses a protecting rail, which comprises a straight section, two buffer sections, two opening sections and a support part, wherein the first opening section, the first buffer section, the straight section, the second buffer section and the second opening section are sequentially connected to form a whole, angles alpha are respectively formed between the first buffer section and the straight section as well as between the second buffer section and the straight section, angles beta are respectively formed between the first opening section and the first buffer section as well as between the second opening section and the second buffer section, each angle alpha is greater than or equal to 168 degrees and is smaller than or equal to 178 degrees, each angle beta is greater than or equal to 160 degrees and is smaller than or equal to 166 degrees, the support part comprises a first support rod and a second support rod, a first through thread hole is formed in the first support rod, a first inserting hole and a second inserting hole are respectively formed in the first opening section and the second opening section, a third inserting hole and a fourth inserting hole are formed in the straight section, the inner walls of the third inserting hole and the fourth inserting hole are respectively provided with internal threads, the free end of the first support rod is inserted into the first inserting hole, and the free end of the second support rod is inserted into the second inserting hole. The protecting rail has the advantage that the strength is further improved.

Description

technical field [0001] The invention relates to a switch rail, in particular to a guard rail. Background technique [0002] The guard rail is an important part of the fixed frog turnout. It is installed on both sides of the frog and is an important device to control the running direction of the wheels, prevent the wheels from impacting in the harmful space of the frog or climb up the tip of the frog core rail, and ensure driving safety. At present, the guard rails used in large quantities on railway turnouts are all machined from ordinary steel rails after being bent, and their surface hardness is not high and are easy to wear. Especially after the train speeds up, the wear speed of the guard rail is faster, which directly affects the service life and driving safety of the guard rail. In addition, the strength of the guard rail itself is not enough, and there is no corresponding mechanism that can enhance the strength of the guard rail in the prior art. Contents of the i...
