Description
Technical Field
The utility model relates to a high-rise technical field who flees especially involves a high-rise escape device.
Background
In recent years, with the increase of economic strength of China, high-rise buildings such as bamboo shoots in spring after raining develop, and according to statistics, the high-rise buildings in the China are about 22 tens of thousands of buildings, the buildings with the height of 24-150 meters are generally called as high-rise buildings, and the buildings with the height of more than 150 meters are super high-rise buildings, wherein the proportion of the super high-rise buildings is only less than 1%, namely most urban people work and live in the high-rise buildings between 24 meters and 150 meters. Therefore, the research of reasonable and efficient rescue and escape equipment and schemes aiming at the range of high-rise buildings in case of fire is urgent and has great market prospect.
At present, the main high-rise fire escape measures at home and abroad are as follows:
1. personal descent control device
The descent control device is used as a reciprocating refuge self-rescue escape device, mainly comprises a rope and a safety belt or a protective sleeve, does not need other power, controls the descending speed of the descent control rope through a braking mechanism, ensures that a user always keeps a certain speed balance by means of self weight and safely descends to the ground slowly, and is an auxiliary safe evacuation product which is most widely applied in the current market. When the reciprocating descent control device works, the transmission gear is driven by the reciprocating descent control device through the rope, the transmission gear drives the brake hub to rotate at a high speed, the friction block of the wheel groove of the brake hub is thrown out, friction force is formed between the friction block and the shell, the gliding speed is controlled and kept uniform, and the user is guaranteed to safely descend to the ground.
2. Retractable escape slideway
The retractable slideway is made of wear-resistant and flame-retardant nylon materials and a high-strength metal ring framework, is folded and stored on a top floor or other floors of a high-rise building at ordinary times, is opened to release the materials to the ground in case of fire, fixes the tail end of the material to an anchoring point predetermined on the ground, and slides down to the ground after trapped people enter the ground in sequence. The principle is that the human body is kept to move at a constant speed in the descending process by the friction force between the human body and the slide way, and the human body can safely reach the ground.
3. Outdoor evacuation rescue capsule
The escape and rescue capsule is composed of one or more escape and rescue capsules which are folded and stored on a roof at ordinary times and a toothed rail installed on an outer wall. In case of fire, professionals use a winch installed on the roof to introduce the unfolded escape and rescue cabin into a sliding rail installed on the outer wall of a building, the escape and rescue cabin can be simultaneously butted with windows of walkways of a plurality of floors, trapped people in a high-rise building are delivered to the ground, and emergency rescue personnel such as firefighters and the like can be delivered into the building when the escape and rescue cabin ascends. Such facilities are far more complex than the first two, require a large one-time investment, need to be used and controlled by specially trained personnel, and require regular maintenance, maintenance and inspection, and the roof winches that power them must be reliably powered. The multi-person wheelchair has the advantages that a plurality of persons can be evacuated every time the wheelchair is operated in a reciprocating mode, the multi-person wheelchair is particularly suitable for evacuating disabled persons taking wheelchairs and other persons with inconvenient actions, and rescue workers can be conveyed to the upper portion when the wheelchair is operated upwards after the wheelchair is operated downwards to convey trapped persons to the ground.
4. High-rise slow-descending equipment
The high-rise slow-falling equipment is also a slow-falling device suitable for high-rise collective escape, and the principle of the slow-falling equipment is that power generated by a loaded lift car in the falling process is utilized to drive a control device arranged in a supporting body of a roof or a refuge layer, and the control device generates directional acting force for preventing the movement of a mechanism through a certain action, so that the whole system reaches a balanced state and realizes uniform slow falling to the ground. The slow descending equipment is mainly characterized in that external power is not needed, a mechanism system automatically realizes a balance state of uniform motion in operation, and the descending speed is within a specified range.
At present, the existing high-rise slow-descending equipment for a prototype is divided into two types, one type is slow descending realized by friction between rope wheels, and the other type is speed limiting principle by utilizing air damping.
However, in the above scheme:
1. the personal descent control device is used for individuals, but is not protected externally, is easy to have fear psychology, is not suitable for old, weak, sick and disabled people by considering psychological factors and high-altitude wind influence, and is only suitable for floors with lower equal ratio below 10 floors; and cannot pass through the disaster area.
2. The escape slideways are used in sequence and collectively, so people with different sizes and weights are difficult to ensure uniform speed, are easy to collide and trample, and are not suitable for hospitals and old people; the material is in contact with the outside for a long time, and the requirement on the service life of the material is high; cannot pass through the disaster area.
3. The outdoor escape capsule and the escape elevator need external power, and the general fire disaster is in a power failure state; if a non-electric power device (such as a diesel engine) is adopted, the whole system is very complex and the normal operation in real time is difficult to guarantee.
4. The high-rise slow-falling device is a domestic high-rise slow-falling device product, and a high-rise rotary wing type slow-falling escape capsule which is developed and produced by only Beijing Nuo Anzhou emergency slow-falling mechanical device company Limited is formed through type tests and verification and popularized to the market at the same time, has the defects of small load and low efficiency, and needs to be fixedly installed on a roof or a refuge layer for centralized evacuation of personnel; the equipment is complex and the transmission is precise; the equipment is expensive (200 w/table);
the existing high-rise building escape technology does not have escape equipment which simultaneously considers the collective escape, the height of a floor, the escape efficiency and the price easy to accept.
