Rail transit beam high-place operation safety protection device

The invention provides a rail transit beam high-place operation safety protection device which comprises a rail beam erected on a pier, a plurality of protection units and a protection net, wherein the protection units are arranged on the rail beam at intervals, and the protection net is arranged in the area between the adjacent protection units on the side face of the rail beam. The protection unit comprises two locking mechanisms and a safety net fixing mechanism; the two locking mechanisms are oppositely arranged on the two sides of the horizontal extending direction of the rail beam in a spaced mode, abut against the outer surface of the rail beam and are detachably connected with the rail beam. The safety net fixing mechanisms are fixedly connected with the two locking mechanisms respectively, the parts, exceeding the width of the rail beam, of the safety net fixing mechanisms extend upwards in the direction away from the upper surface of the rail beam to form hanging parts of theprotection net, and the
