The utility model relates to a safety protection device for a top cover and a
machine pit lining, which aims at solving the problems that a traditional
safety net is complex in installation, poor in stability and easy to loosen and damage, and specifically comprises a foot plate and a traction mechanism, one side of the foot plate is fixed on the foundation pit lining through the traction mechanism, and the other side of the foot plate is lapped on an equipment top cover; the traction mechanism is composed of a C-shaped plate, a euphroe, a steel
wire rope and a fixing
assembly, the C-shaped plate is fixed to a foundation pit lining through a bolt set, the euphroe is connected with the steel
wire rope and adjusts the position of a foot plate, and the steel
wire rope is doubly locked through a heart-shaped ring and a steel wire
rope clamp. The foot plates adopt
modular design, clamping grooves are formed in the two ends and spliced to form an annular protection area, and reinforcing ribs and steel
wire mesh plates are arranged in the middle to enhance the
impact resistance. Through a
modular structure, dynamic adjustment and high-stability connection, rapid installation and stable protection are achieved, the device is adaptive to different unit sizes, the edge
falling risk is remarkably reduced, and the overhaul efficiency and safety are improved.
