Problems solved by technology

Although most high-rise buildings are equipped with safe evacuation passages, in the event of explosions, fires and other emergencies, it is difficult to evacuate a large number of people gathered in the building in time, quickly eliminate dangers, and rescue trapped people. Therefore, building installation The use efficiency of the configured life-saving device is particularly important
[0003] At present, the existing life-saving devices suitable for the escape department of the building are preferably the slow-down device without power supply mechanical conduction, such as: the electric escape ladder outside the building, that is, the sprocket and chain are installed on the outside of the building against the wall. And the top-down chain conveyor line composed of matching folding ladders, relying on the weight of the escaping body to drive the sprocket to rotate, so as to achieve the purpose of descending and escaping from the outside of the building, but the problem is that the device is exposed to the outside of the building all the year round. Externally, the material used is all stainless steel, which is expensive and difficult to maintain. The fundamental problem is that the device can only convey escape personnel from top to bottom to meet the needs of escape, but cannot meet the requirements of lifesaving. Rescuers cannot pass through the device Arrive at the disaster site in time for disaster relief
Other life-saving devices include straight-type flexible life-saving slides, which are similar to slides and snake-shaped cylindrical life-saving slides. They are installed on the outer wall of each stair passage window from top to bottom, and each passage window corresponds to an escape hole. Users can escape the accident scene from the outside of the building through the life-saving slide, and control the descending speed through the change of the diameter of the slide, so as to achieve the purpose of safe and slow descent. Exposed on the outside of the building, it is easy to age, and it is still only for escape, not for lifesaving
Some car-type life-saving descent devices disclosed recently can meet the needs of transporting escape personnel and life-saving personnel up and down, but the number of personnel transported at a time is small, the efficiency is low, and the defects in structural design make it difficult to improve safety and operational reliability. Sufficient protection lays hidden dangers for safe use

Embodiment 1

[0043] The life-saving slow-descent device is attached figure 1 , 2 As shown, it is mainly composed of air damping slow-down mechanism I, rescue cabin II, layered braking mechanism III, lifesaving platform IV, platform moving mechanism V, balancer VI, empty storage mechanism VII, wheelchair lifting mechanism VIII, and steel rope guide An adjustment mechanism IX, a flexible lifesaving slideway X, a support chassis XI, and a solar battery XII are formed. The lifesaving platform IV is the supporting body of the overall support structure, surrounded by tempered glass, and its bottom plate is the supporting table; the flexible lifesaving slideway X is located at the protruding part of the front end of the lifesaving platform IV; the lifesaving cabin II is two symmetrical, located The front part of the lifesaving platform IV; the air damping slow-down mechanism I, the balancer VI, the empty storage mechanism VII, and the wheelchair lifting mechanism VIII are fixedly installed on th...

Embodiment 2

[0061] Such as image 3 Another kind of life-saving slow-descent device shown, its structure is basically similar to embodiment 1, the difference is in order to be able to overcome the hindrance of the parapet wall that is set for safety on the roof of a general building, so that the life-saving slow-descent device can extend Out of the building, the support base XI installed under the lifesaving platform is flush with the top surface of the safety protection wall, a foot ladder 111 is installed in the middle of the rear side of the support base XI, and the lifesaving platform IV passes through 43 track beams installed at the bottom Fall on the pulley block 44, the pulley block 44 is fixed on the upper part of the support chassis XI, and a platform moving mechanism V is installed on the side of the support chassis XI, and the hand wheel 54 of the shaking platform moving mechanism V can be seated on the pulley block 44. The rescue platform IV moves back and forth, stretches out...

Abstract

The invention relates to a life-saving slow descending device which mainly comprises an air damping slow descending mechanism, a life saving bin, a life saving platform, a steel rope, a steel rope guiding adjustment mechanism and a supporting underframe; the life saving platform is a supporting body with a bracket structure; a bottom plate of the life saving platform is a supporting table-board; the life saving platform is supported by the supporting underframe; the life saving bin is positioned at the front part of the life saving platform; the life saving bin has two paired bins; the life saving platform is provided with a balancer and a hollow bin receiving and releasing mechanism; the air damping slow descending mechanism, the balancer and the hollow bin receiving and releasing mechanism are fixedly arranged on the rear part of the life saving platform; and one side of the life saving platform is provided with a safety door with an in-and-out platform. The life-saving slow descending device has a reasonable structure, ensures the use safety and reliability, easy management of operation and maintenance and is suitable for crowds to escape.

Description

technical field [0001] The invention relates to a rescue tool, in particular to a slow-down device for rescue and escape of a high-rise building. technical background [0002] At present, with the rapid development of our country's economic construction, the tension of urban land makes urban buildings continue to develop into groups and super-high buildings. Their structures are becoming more and more complex, and the population density is increasing. It has become the focus of attention of architectural designers, residents and staff. Although most high-rise buildings are equipped with safe evacuation passages, in the event of explosions, fires and other emergencies, it is difficult to evacuate a large number of people gathered in the building in time, quickly eliminate dangers, and rescue trapped people. Therefore, building installation The use efficiency of the configured life-saving device is particularly important. [0003] At present, the existing life-saving devices...
