High-altitude escape backpack and rope retractable descent control device thereof

Abstract

The invention discloses a high-altitude escape backpack and a rope retractable descent control device thereof. The high-altitude escape backpack comprises a fixing frame; a hub rotatably mounted on the fixing frame and used for winding a rope; and a fixing groove formed in the hub and used for fixing the end of the rope. A guide mechanism used for guiding the rope is further arranged on the fixing frame, the guide mechanism comprises a first roller set and a second roller set, and the first roller set and the second roller set are perpendicular to each other; the first roller set is composed of two first guide rollers arranged in parallel; and the second roller set is composed of two second guide rollers which are arranged in parallel, and the second guide rollers for the rope to be wound are rotationally sleeved with shaft sleeves. By arranging the first roller set and the second roller set, the rope is positioned to limit the rope outlet position, the balance of the descent control device is guaranteed, and therefore the safety is improved.

Description

technical field [0001] The invention belongs to the technical field of escape equipment, and in particular relates to a high-altitude escape backpack and a retractable rope descending device thereof. Background technique [0002] At present, the pace of urbanization is getting faster and faster, and the tension of urban land has led to more and more high-rise buildings. When disasters such as fires occur on high floors, people have limited ways to evacuate the accident site, and the risk factor is high. In this context, high-floor slow-descent escape equipment was born. However, the deceleration mechanism of the current slow-descent escape equipment has low reliability and poor slow-down effect, which makes the safety performance of the slow-descent escape equipment low. If it is possible to use would have extremely serious consequences. [0003] The existing slow-descent escape equipment does not limit the exit position of the rope, resulting in poor balance and low safety...
