Description
Technical Field
The invention belongs to the technical field of fire lifesaving appliances, and particularly relates to a locking mechanism of a high-rise fire lifesaving device.
Background
At present, as a large number of people rush into a large city, the urban environment is more crowded, and urban land resources are scarce, so that newly built buildings are higher and higher to relieve urban pressure. However, the fire escape system brings a series of safety problems such as fire fighting and escape, and in case of fire on the bottom floor, people on a high floor can only continue to walk to the upper floor until the people escape from the top of the building. Because the existing buildings are very high, the fire truck can not extinguish the fire of the high-rise floors, and if the fire fighting facilities of the floors cannot extinguish the fire, the fire is likely to go further upwards, and finally people who escape from the roofs are endangered.
At present, some buildings with few floors are provided with escape ropes, the bodies of people are sleeved in rope loops, then the people can automatically control the descending speed, and the people are descended from the top to the ground. In addition, for the old, the weak, the sick and the disabled and the people with high fear, the escape way by the rope on the bottom floor is very unsafe.
Therefore, a high-rise escape machine appears in the industry, a winding drum and a transmission mechanism are arranged to receive and release a rope, and then the receiving and releasing speed is controlled through a motor and a brake, so that a person can put down a frame body from the top of a building to the ground. However, there are many problems with existing escape engines.
Firstly, the frame body of the escape apparatus is suspended on the roof and can be easily bound on the frame body for healthy young people, but when the escape apparatus is used in a hospital place, the escape apparatus is difficult to operate for the old, particularly for the people with physical disabilities, and a patient needs to be placed and bound on the frame body by several people.
In addition, although the conventional escape apparatus is driven by a motor, there is a possibility that power cannot be supplied when an accident occurs in a building. Even if the escape machine is provided with the battery, the electric quantity of the battery is reduced after the battery is placed for a period of time, the battery cannot be used when an accident happens, and the battery is likely to lose effectiveness under the environmental action of a roof for a long year.
