Abstract

The invention discloses a fall-preventing device for ropes and round bars. The fall-preventing device comprises a body, a rotating arm, two connecting plates, a movable block and a pull ring, wherein a V-shaped through groove is formed in one end of the body; a strip sliding chute is formed in the other end of the body; the rotating arm is rotationally connected with the body at the middle position; the movable block is arranged between the rotating arm and the body and is positioned on one side of an opening of the V-shaped through groove; the two connecting plates are oppositely arranged on two sides of the body; one end of each connecting plate is rotationally connected with one end of the rotating arm; a spring is arranged at the rotationally-connecting part; the other end of each connecting plate is rotationally connected with the pull ring through a pin roll; and the pin roll penetrates through the strip sliding chute in the body. According to the fall-preventing device disclosed by the invention, due to the adoption of a cam type five-link mechanism, a brake torque is increased; by adopting a V-shaped through groove structure, the fall-preventing device is more suitable for fixing the ropes and the round bars; by adopting a rotary movable block structure, the size of the rotating arm and the size of an integral structure are reduced and meanwhile, the brake torque is increased; and by adopting a spring locking structure, the mechanism is always positioned in a locking state.

Description

technical field [0001] The invention relates to a safety device for working at heights, in particular to a fall arrest device for rope type and round bar type. Background technique [0002] The traditional high-altitude operation is that the staff wears a safety belt, and the other end of the safety belt is hung on the fixed fulcrum of the belt. The disadvantage is that the movement range of the staff is small. Present high-altitude operation is, the staff wears safety belt, and the other end of safety belt is hung on the fall arrester, and fall arrester is fixed on the guide rail, and guide rail is general profile or rope. The disadvantage of the anti-fall device using profiles as guide rails is that the guide rails are too heavy, which is not conducive to transportation and installation, resulting in high costs. The anti-falling device using the rope as the guide rail type has a cam-type four-bar linkage mechanism and a slider-type five-bar linkage mechanism. The disad...
