Description

Quick recovery unit of emergency ladder

Technical Field

The utility model belongs to the outdoor field of fleing of saving oneself of building relates to a quick recovery unit of emergency ladder, especially relates to a quick recovery unit of emergency ladder that uses on the outdoor emergency ladder of aluminum alloy of installation on high-rise resident family and the high-rise public office space.

Background

Along with the continuous propulsion of urbanization process, high-rise building quantity is more and more, and high-rise building self number of piles is many, and the floor is higher, and inner structure is complicated for it is higher to realize the degree of difficulty of fleing from as early as possible after the conflagration takes place, and in addition high-rise building's the number of people of living is more, and when the conflagration flue gas stretchs, visibility receives the influence, and the degree of difficulty that the personnel of evacuating the very first time escaped from high-rise building promotes sharply. A plurality of fire cases show that the existing fire rescue means can not adapt to the development speed of high-rise buildings, and a novel outdoor escape system needs to be designed and developed according to the fire characteristics of the high-rise buildings and the technical conditions of fire-fighting escape equipment.

The outdoor escape system is not easy to be threatened by smoke and fire, and not only can be used for evacuating personnel, but also can be used for firefighters to ascend a high building for saving life. Structurally, the foldable solar energy building can be folded and contracted, and does not occupy effective indoor building area. In addition, the smoke invading the stairs can be blown away by wind quickly and is not influenced by the wind direction. Therefore, the air-permeable building has good ventilation diffusivity and economy, and can add a festoon to the exterior of the building when the modeling is well processed. Along with the development of economy, building height and structural variation are various, and indoor fire phenomenon takes place occasionally, and evacuation often accompanies the casualties in the building, so this outdoor escape system walks into masses 'field of vision, because of its have safety protection concurrently, trigger characteristics such as folding, convenient to use, appearance pleasing to the eye, bearing capacity are good, receive building developer's liking deeply, outdoor escape system market demand is huge.

Present outdoor escape system uses in the use, need to use the back with the activity frame bullet of emergency ladder, and people escape in emergency ladder inside when the conflagration breaks out, nevertheless because the emergency ladder is because the spring resumes the activity frame expansion that deformation brought, therefore the emergency ladder is when retrieving, has following problem: 1. because the tensioning force of the spring is too large, the movable outer frame of the escape ladder can be recovered by 7-8 persons with brute force at the same time, and the recovery of the escape ladder is inconvenient and wastes manpower. 2. The escape ladder recovered by manpower has the disadvantages that the buckle device in the escape ladder is difficult to install and the construction efficiency is low if the escape ladder cannot be recovered. 3. The recovery of emergency ladder often need carry out the operation at the high altitude, when the emergency ladder frame is retrieved to the manpower, has safe risk.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model discloses a solve above-mentioned recovery difficulty, extravagant manpower, the low, the high altitude construction of efficiency of construction that exist of current emergency ladder activity frame recovery in-process and have the risk scheduling problem, provide a quick recovery unit of emergency ladder, have retrieve convenient and fast, the high, high altitude construction factor of safety characteristics of efficiency of construction.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a quick recovery unit of emergency ladder, including the sliding guide who sets up the external screw thread and with sliding guide fixed connection's handle, the last activity of sliding guide cup joints the activity buckle that is arranged in joint escape system unsettled frame, and the fixed buckle that is arranged in joint escape system fixed frame is cup jointed to the handle of one side relative with the activity buckle.

Furthermore, a limiting gasket is fixedly mounted on the handle outside the fixed buckle. Has the advantages that: the limiting gasket is fixedly connected with the handle in a welding mode, and plays a role in limiting the position of the fixed buckle

Further, a nut is installed on the free end of the sliding guide rail through threads for locking. Has the advantages that: the nut at the free end of the sliding guide rail can prevent the movable buckle from slipping.

Furthermore, the clamping end of the movable buckle and the fixed buckle is in a shape of a rounded horn. Has the advantages that: the horn-shaped movable buckle of radius, fixed buckle can prevent with unsettled frame, fixed frame fish tail.

Further, the twisting end of the handle is fixedly provided with anti-skid grains. Has the advantages that: the anti-slip lines on the handle play a role in preventing the hands of the operator from slipping.

The beneficial effects of the utility model reside in that:

1. the utility model discloses a quick recovery unit of emergency ladder retrieves conveniently, only needs to wave the outer unsettled frame of emergency ladder just can be retrieved to the handle alone, has solved the problem that needs a large amount of manpowers to retrieve in the recovery process of escape system.

2. The utility model discloses a quick recovery unit of emergency ladder, the efficiency of construction is high, can be convenient after retrieving unsettled frame through this quick recovery unit twist the switch locking soon in opening the mechanism, and the high-efficient accurate swift installation of opening the mechanism on the emergency ladder of being convenient for can not appear because unsettled frame retrieves not in place, the fixed problem of opening the mechanism locking of being not convenient for.

3. The utility model discloses a quick recovery unit of emergency ladder for the emergency ladder can be indoor retrieve, even high altitude construction does not have the risk yet.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.
