Problems solved by technology
Using this method to implement lifesaving, the longer the cloth bag, the larger the volume, and it can only be used in a range with a small number of layers, otherwise one or two people cannot operate it
At present, some people in the market use the deceleration mechanism used in machinery as a life-saving device for high-rise buildings, but its structure is relatively complicated, and its production cost is high, and its volume is also large.

Embodiment 1
[0013] See Figure 1 ~ Figure 3 , The picture consists of a spindle (1) with a square head at one end, a 21-tooth internal tooth turntable (2) is fixed on the spindle (1), and a single head with double teeth is installed in the internal tooth turntable (2) The speed-limiting slider (3) of the main shaft (1) is equipped with a frame (4) outside the internally toothed turntable (2) on the main shaft (1). The frame is equipped with a pair of bearings (7) at both ends of the main shaft; A rope reel (5) etc. are installed at one end. When in use, as long as the heavy objects or personnel are tied to the lower end of the rope reel, the gravity can be used to implement the speed limit descent.

The present invention discloses a weight or staff speed-limiting falling device. It is characterized by that it comprises a main shaft whose one end is equipped with a square head component, on the main shaft an inner gear rotating disk is fixed, and in said inner gear rotating disk is equipped with a toothed speed-limiting slide block, a machine frame is mounted on the exterior of said inner gear rotating disk, and said machine frame is equipped with a pair of bearing at two ends of main sahft, a rope reel is mounted on another end of the main shaft. Said invention also provides its working priciple for implementing said goal.
Description
Technical field [0001] The invention relates to a mechanical speed-limiting device, in particular to a descender for automatic speed-limiting of heavy objects or persons. Background technique [0002] With the progress of society and the continuous development of science and technology, people's living standards have also been continuously improved. In the construction industry, the number of high-rise buildings in cities and towns is also increasing. Since the "September 11" incident occurred on September 11, 2001, fire protection and rescue of high-rise buildings have become an important issue. At present, when a fire occurs on the lower floors of high-rise buildings, the fire department can only use high-rise stairs to save people. The height of the stairs is extremely limited, and the speed of saving people is also slow, so it is not suitable for the current needs. With regard to the life-saving problems of high-level personnel, they can only carry out self-rescue under the e...
