Embodiment 1

[0018] See attached figure 1 , 2 , 3, the automatic slow-down device includes a body 1, a rotating wheel 2, a damping body 3, a central shaft 4, an end cover 5, a counterweight 6 and a slow-down rope assembly. Slow down rope 71 is arranged in the rope groove 21 of rotating wheel 2, and one end of slow down rope 71 is connected with the people or object that need to descend slowly, and the other end is connected counterweight 6. Several grooves 22 are arranged on the circumference of one end of the rotating wheel 2 , and damping bodies 3 are arranged in the grooves 22 , and the damping bodies 3 can slide in the grooves 22 . The end cover 5 includes a front end cover 51 and a rear end cover 52 respectively disposed on the front end surface and the rear end surface of the body 1 . The central shaft 4 is installed in the rotating wheel 2, and the rotating wheel 2 is installed in the circular hole 11 of the body 1, and the rotating wheel 2 can rotate around the central shaft 4. ...

Embodiment 2

[0020] See attached Figure 4 , the present embodiment is different from the embodiment in that the round hole 11 of the body 1 is made of nylon and the shell of the body 1 is made of metal, and the rest are the same as in the first embodiment.

Abstract

The invention discloses an automatic slow-drop device which is suitable for the fields such as fire escape, overhead operation protection, physical training and the like. The automatic slow-drop device comprises a machine body, a rotary wheel, a damping body, a central shaft, an end cover, a counterweight part and a slow-drop rope assembly, wherein one end of the slow-drop rope is connected to a person or an object which needs to slowly drop, and the other end of the slow-drop rope is connected with the counterweight part; while the person or the object drops, the rotary wheel and the dampingbody are driven to rotate, the damping body generates reverse torque on the rotary wheel under action of the inner circle of the machine body, especially a wedge-shaped groove in the inner circle of the machine body, and the reverse torque is increased along with increase of drop speed of the person or the object; while the reverse torque is equal to torque generated by dead weight of the person or the object, the drop speed is not increased again, so that uniform-flow slow drop of the person or the object is realized. While the person or the object is still and moves upwards, the counterweight part can keep the slow-drop rope in a tightening state, so that the person or the object which needs to slowly drop is guaranteed to be under protection of the slow-drop device all the time.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a device that can instantly protect a person or object from moving or standing still in the air and automatically slow down, which is suitable for fire escape, high-altitude operation protection, rock climbing and physical training and other fields Background technique [0002] In production and life, it is often necessary for people to take the initiative to slow down and escape from high places when they are working at high places in the air or encounter disasters such as fires in high-rise buildings. Especially when working at high places (in the air), such as construction installation, rock climbing and physical training, etc., the position of the staff needs to be moved. In order to prevent the staff from falling or take the initiative to slow down the staff, the ground staff must use more complicated mechanisms. for protection. Such a protection method has poor security and high labo...
