Specifically, the body 1 is made of aluminum alloy or stainless steel, the body 1 is in the shape of a long rod, a handle body for installing the rope supporting portion 3 extends leftwards from the top of the body 1, the friction shaft 32 is arranged at the upper end of the body 1, the bearing shaft 31 is arranged at the right lower side of the friction shaft 32, the rope protecting shaft 5 is arranged above the friction shaft 32, and the friction wheel 21 is fixedly arranged on the body 1 and arranged below the bearing shaft 31. The brake wheel 22 is connected to the body 1 through a rotating shaft and is arranged below the friction wheel 21. The rope threading clearance of the safety rope 6 is arranged between the friction wheel 21 and the braking wheel 22, the handle 23 and the braking wheel 22 are integrally formed, and the handle 23 and the braking wheel 22 are synchronously linked.
When the descender descends, the safety rope 6 pulls the braking pulley 22 to rotate clockwise, and as the braking pulley 22 rotates clockwise, the end of the braking pulley 22 makes the clamping force of the safety rope 6 on the friction pulley 21 larger, i.e. the friction force of the safety rope 6 between the friction pulley 21 and the braking pulley 22 is larger, and when the braking pulley 22 rotates to a certain angle in the clockwise direction, the safety rope 6 is finally clamped and fixed between the friction pulley 21 and the braking pulley 22.
The descender is hung at descender's waist through external instrument, needs to wind safety rope 6 before using and establishes the installation: firstly, the movable side plate is shifted to rotate to a preset angle, and then the safety rope 6 is sequentially wound on the bearing shaft 31 and the friction shaft 32 from top to bottom from one side of the body 1, passes through the bottom of the braking wheel 22 and is wound on the friction wheel 21; after the safety rope 6 is installed, the descender is closed, namely the movable side plate is stirred to coincide with the body 1, so that the safety rope 6 is fixed in the descender. Therefore, in use, the aerial braking of a descender is realized through the matching of the braking wheel 22 and the friction wheel 21, and the safety rope 6 is wound on the bearing shaft 31, the bearing shaft 31 bears about half of the weight of a human body, so that the load borne by the braking wheel 22 is reduced, the handle 23 is easy to control, the strength can be saved during descending, the descending is smooth, the bearing capacity of the device is improved, the braking can be more effectively carried out, and the braking is more convenient and safer.
To further illustrate the braking process, the friction wheel 21 has a first inclined surface 211 and a second inclined surface 212. The brake wheel 22 has an edge 221, and the edge 221 is disposed corresponding to the first inclined surface 211.
