Abstract

The invention discloses a speed controller and relates to the technical field of high-rise building emergency escape equipment. The problems that in the prior art, the load borne by a speed controller is small, the rescue efficiency is low, or the size is large are solved. The speed controller comprises a mounting base, a shell, limiting check blocks, reset springs, a rope locking mechanism, a rope wheel, a mandrel, a speed limiting mechanism and a speed reduction mechanism. The actual descending speed of an escape device is reflected through the centrifugal force generated when a working steel wire rope of the high-rise building escape device is wounded on the rope wheel of the speed controller and rotates, the tension moment generated by descending of the escape device is balanced by friction moment generated by the speed reduction mechanism through the centrifugal force, when the descending speed of the escape device exceeds a specified limit speed, a centrifugal ratchet flail block of the speed limiting mechanism is unfolded under the action of centrifugal force and drives the rope locking mechanism to rotate, a gap between a rope clamp of the rope locking mechanism and the rope wheel is narrowed, the working steel wire rope is clamped, and accordingly the purpose of speed reduction and limiting is achieved.

Description

technical field [0001] The invention relates to the technical field of emergency escape equipment for high-rise buildings, in particular to a speed controller. Background technique [0002] At present, the speed controller of special equipment for high-rise escape mainly adopts mechanical methods such as friction damping, liquid damping and air damping to control the speed. The speed controller relying on frictional damping converts the gravity into a balanced resistance to realize the uniform descent of the escape special equipment. This kind of equipment can bear a small load, the rescue efficiency is low, and the friction coefficient decreases due to long-term use. Without a stall protection mechanism, the descending speed is out of control and dangerous; a speed controller with liquid damping or air damping is used to convert the potential energy of the escape device into the internal energy of liquid or air. This kind of equipment is generally bulky. Therefore, the spe...
