Descent control device and escape device

Abstract

The invention discloses a descent control device and an escape device. The descent control device comprises a winder, a damper and a locking device, wherein the winder comprises a rope, a winding wheel for winding the rope and a volute spiral spring connected with the winding wheel; the damper is connected with the winding wheel; a plurality of teeth distributed along the circumference are arranged on the outer edges of the two sides of the winding wheel; and the locking device comprises a lock catch and a first transverse shaft. The rope of the winder is connected with an escape platform, andthe winding wheel is locked through buckling of the lock catch of the locking device and the teeth on the winding wheel, so that the escape platform is fixed, escape personnel can stand stably on theescape platform and then carry out unlocking operation, and the operation safety of the escape personnel is improved; and under the action of damping force of the damper, the winding wheel slowly releases the rope, so that the escape platform is guaranteed to stably descend, and the safety of the escape personnel is guaranteed. The descent control device and the escape device are used for the technical field of escape devices.

Description

technical field [0001] The invention relates to the technical field of escape devices, in particular to a descending device and an escape device. Background technique [0002] At present, the fire escape of high-rise buildings mainly relies on indoor stairs, but if the disaster occurs in the middle and lower sections of the building, it is difficult for the people on the upper floors to be evacuated effectively due to the influence of dense smoke. There are the following problems in the slow descent device for rope descent escape: the descent speed is manually controlled by the escape personnel, and the escape personnel are suspended in the air. It is difficult to do it by yourself. In order to solve the above problems, an escape platform between the floors of the balcony or the escape shaft can be used. Escapers stand on the escape platform and descend through the escape platform. However, how to realize the smooth descent of the escape platform and ensure the safety of th...
