Container transport semi-trailer side guard

Abstract

The utility model provides a container transport semitrailer side guardrail relates to vehicle engineering field, the utility model discloses side guardrail main part, the utility model discloses when using when the side guardrail main part is installed in the chassis both sides of semitrailer through mounting frame contact bolt installs the water tank and oil tank etc. part installed to its side protection, if the side guardrail main part collides or scratches with other objects, will preferentially collide and scratch to the anti -collision net board, pushes to one end, drives piston rod to slide in the air cylinder inner wall one end, extrudes its inside air into the air bag inside, makes its air bag collision, the one side of anti -collision net board is buffered, and if a plurality of damper also will be buffered between support and anti -collision net board, to this to slow down the impact intensity and scratch situation that receives, to this avoids the side guardrail main part directly stressed and produces the possibility of deformation, weld point drop and even component fracture, improves the service life of side guardrail main part, reduces the frequency and cost of maintenance replacement.
