Problems solved by technology
At present, emergency escape descent devices for high-rise buildings generally convert the gravity of a person into a frictional resistance that is balanced with gravity through a friction damping mechanism to achieve a uniform descent of a person. Speed out of control, no stall protection mechanism is easy to cause accidental injury, inconvenient adjustment, short service life and other problems, the reliability of the slow descent device needs to be further improved

The invention relates to a centrifugal friction-type descent control device with frictional compensation and speed reduction protection, belonging to the field of high-rise building emergency escape equipment. The centrifugal friction-type descent control device comprises a descending device, a speed change device, a speed reduction protection device, a centrifugal friction speed limit device, a friction compensation device, an installation fixing device and a shell, wherein the descending device, the speed change device, the speed reduction protection device, the centrifugal friction speed limit device and the friction compensation device are all arranged in the shell; and the installation fixing device is connected with the shell. The descent control device provided by the invention is in a centrifugal friction-type structure, has the advantages of being compact in structure, simple to operate, high in reliability, high in stability and low in processing and manufacturing cost, and is suitable for being used for descending and escaping from the high-rise building at an emergency situation.
Description
technical field [0001] The invention belongs to the field of high-rise building emergency escape equipment. In particular, it relates to the structural design of the escape descent device. Background technique [0002] With the progress of society and the acceleration of urbanization, high-rise buildings have sprung up like mushrooms. At the same time, the potential safety hazards of high-rise buildings have gradually attracted people's attention. Aiming at the escape market of high-rise buildings, special escape equipment has appeared in the escape market, such as escape descent devices. It is a safety escape device that allows people to slowly descend along (with) ropes (belts) due to their own weight. At present, emergency escape descent devices for high-rise buildings generally convert the gravity of a person into a frictional resistance that is balanced with gravity through a friction damping mechanism to achieve a uniform descent of a person. The speed is out of con...
