Anti-collision fence convenient to maintain

The invention relates to the technical field of industrial automation, in particular to a crash barrier convenient to maintain, which comprises an intercepting assembly, a blocking piece, a buffer block arranged on the outer wall of the blocking piece, reinforcing rods arranged on the two sides of the blocking piece, and a buffer piece arranged on the outer wall of the blocking piece; the rotatable and telescopic roller is additionally arranged on the outer surface of the crash barrier, after the crash barrier is installed in the side direction of a vehicle, the vehicle can be guided to deviate, damage caused by vehicle collision is reduced, and meanwhile the risk of vehicle rollover is reduced; meanwhile, the device is independently arranged in a row, so that the crash barrier is more convenient to replace after being damaged by collision. Compared with the prior art, the anti-collision fence has the advantages that collision blocking occurs in a small range and does not affect too much collision, and even i
