Low-speed, reciprocating emergency escape ladder for high altitude

Abstract

The invention discloses a low-speed reciprocating high-altitude lifesaving ladder, aiming at realizing high-altitude multiple persons continuous salvation and controlling the sliding speed of a lifesaving rope. The solution is that a pivoted swing arms (14) are arranged on two side supporting boards (3) of the main framework of the high-altitude lifesaving ladder, connecting holes (18) on the pivoted swing arms (14) match with a main frame connector (36) which bears a fixed supporting part; the main frame body is in clamping transmission connection with a lifesaving rope (6) the carrying partof which is n-shaped through a pair of transmission mechanism in mirror symmetry on a positive and a negative pressure boards of a control part, slowly-locking devices (7) are respectively arranged on extended parts of the two end of the n-shaped lifesaving rope (6); a timing part is arranged on the transmission mechanism of the control part. The lifesaving ladder of the invention is compact, light, economical, practical, simple, feasible, and convenient for installation, is applicable for multiple persons escaping continuously when high building encounters fire or danger, can send the savingpersons from the window to the ground safely and quickly, and can ensure the persons to withdraw from the danger zone quickly.

Description

Technical field: [0001] The invention relates to a fire-fighting and high-altitude life-saving equipment, in particular to a high-altitude life-saving ladder capable of slow descent at high altitude and reciprocating rescue, which is suitable for standby in high-rise hotels, hotels, office buildings and places with high fire occurrence. Background technique: [0002] At present, in terms of life-saving in fire-fighting facilities, there is no ideal life-saving product that can replace the multi-million-dollar fire-fighting rescue vehicle. According to my current knowledge, the current self-developed high-altitude life-saving equipment is unsafe and inconvenient to use. Insufficiency, such as: the existing life-saving equipment, the coherence is not good in the rescue, can not achieve continuous rescue, it is very troublesome to rescue many people, after the rescue of the first person, the life-saving rope needs to be retracted to realize the rescue. Rescuing the next person,...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a slow-speed, reciprocating high-altitude life-saving ladder in order to solve the disadvantages of unsafe, inconvenient and fast, etc., in order to solve the problems that the above-mentioned prior art cannot realize high-altitude continuous rescue and the sliding speed of the life-saving rope cannot be controlled during rescue. It includes: the host body placed in the host frame, the load-bearing and fixed support part movably connected with the host frame, the support plates (3) on both sides of the host frame are equipped with movable swing arms (14), and the movable swing arms (14) The connecting hole (18) on the upper part is matched with the host connector (36) carrying the fixed support part; the host body is combined into a mirror image A pair of symmetrical transmission mechanisms are clamped and connected with the Z-shaped life-saving rope (6) on the load-bearing part, and the two ends of the Z-shaped life-saving rope (6) are respectively equipped with slow locks (7); There is a speed regulating part on the transmission mechanism of the control part
