Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

the utility model provides a railway protective fence, includes parallelogram fence body 7, fence body 7 is including the last frame 1 and the lower frame 2 that are parallel to each other and two side frames 3 that are parallel to each other, it articulates each other end to go up frame 1 and lower frame 2 and two side frames 3, goes up and is equipped with a plurality of fender rods 4 that are on a parallel with side frame 3 between frame 1 and the lower frame 2, the both ends of fender rod 4 are articulated with last frame 1 and lower frame 2 respectively. The upper frame 1 and the lower frame 2 adopt rectangular pipes of 40 × 60 × 2.0mm, the side frame 3 adopts square pipes of 80 × 2.5mm, the guard bar 4 adopts rectangular pipes of 20 × 30 × 1.5mm, the surface treatment of the fence body 7 adopts hot-dip galvanizing or multi-component alloy co-infiltration passivation treatment, and the fence body has high corrosion resistance and long service life.
