Anti-falling structure for racking I-shaped steel and hydraulic support

The anti-falling structure comprises a connecting piece and a blocking piece, the connecting piece is arranged in the vertical direction and detachably connected with the front end of a top beam of the hydraulic support, the blocking piece is arranged in the horizontal direction, and the two ends of the blocking piece are the connecting end and the free end respectively. The connecting end of the blocking piece is connected with the top end of the connecting piece, the free end of the blocking piece plays a role in blocking the upper frame I-shaped steel located above the hydraulic support, the limiting blocking device is simple in structure, low in cost and convenient and fast to install, the upper frame I-shaped steel can be effectively limited and blocked, sliding of the upper frame I-shaped steel is avoided, potential safety hazards are eliminated, and the working efficiency is improved. And the racking time of the racking I-shaped steel can be shortened, and the construction efficiency is improved. 本实用新型
