Abstract

The invention discloses an anti-rockfall device for a railway track in the field of tunnel rockfall prevention. The device comprises baffles, a track and a roadbed, the baffles are arranged on the two sides of the track at a tunnel portal, the baffles are rotatably connected to the roadbed through second rotating shafts fixedly connected with the baffles, and first gears are fixedly connected to the second rotating shafts; and the first gears are meshed with second gears, and the second gears are fixedly connected to first rotating shafts rotationally connected with a roadbed. The problem that in the prior art, rockfall cannot be effectively prevented under the condition that a groove is not formed in a mountain to install a baffle is solved.

Description

technical field [0001] The invention relates to the field of rockfall prevention in tunnels, in particular to a rockfall prevention device for railway tracks. Background technique [0002] In the prior art, for the prevention of rockfall at the railway entrance, the baffle plate is usually embedded on the mountain body through the card slot opened on the mountain body. Although this can have a certain anti-rockfall function, opening the groove on the mountain body will further cause the mountain body to fall. Looseness will increase the possibility of falling rocks. In addition, the general anti-falling stone slabs are usually huge and made of reinforced concrete. The cost is extremely high and it is very difficult to replace. If the railway to be protected is longer, the cost will be further increased. [0003] The baffles in the prior art are usually easy to accumulate gravel due to their relatively large size. In the long run, the burden on the baffles will be increased, ...
