Escape device for urgently evacuating personnel in public places and high-rise buildings

Abstract

The invention relates to an escape device for helping to quickly evacuate trapped personnel in public places and high-rise buildings when an emergency happens. The escape device is provided with a sliding friction block and a slide rail, wherein the sliding friction block comprises a central control shaft (13) and a peripheral umbrella-type folding and unfolding mechanism system; the lower end of the central control shaft is provided with a stringing ring (10); the body of the central control shaft is sleeved with four motion blocks; the motion blocks is connected with a peripheral friction plate (8) through the umbrella-type folding and unfolding connecting rod mechanism; a spring (9) is arranged below the second motion block; and the slide rail adopts a round pipe in sectional connection, the pipe is provided with a slot for positioning, and the tail end of the pipe is provided with a section of arc-shaped pipe. The escape device has the main characteristics that: a friction force which is in a certain proportion to the gravity of evacuees can be generated, so that the aim of reducing the speed is fulfilled, and the trapped personnel can safely escape and reach the ground; and the device has a simple structure and convenient operation, and is suitable for the public places and residential houses.

Description

technical field [0001] The invention relates to an escape device, in particular to an escape device for helping trapped people in public places and high-rise buildings to evacuate quickly when an emergency occurs. Background technique [0002] With the improvement of people's living standards, various buildings have sprung up, expanding people's living space. However, the relatively closed space has also brought many problems, one of which is the safe escape link: when the building When an internal emergency occurs and it is urgent to evacuate the trapped people, it is often difficult to complete the evacuation work smoothly. For example, when a fire broke out, the imperfection of existing fire protection measures and the limitations of escape methods have caused many tragedies. Although the fire department vigorously promotes the knowledge about fire escape, tragedies continue to occur due to the limitations of evacuation measures. [0003] The most common means of evacuat...

Problems solved by technology

Among them, emergency exits relying on the interior of the building are usually blocked by building users for anti-theft considerations, and it is difficult to play an effective role. Even if there is no blockage and blockage, stampede incidents will occur due to the panic of people; Complicated maintenance and testing must be done on a regular basis, and the installation can only be done after major changes to the building; the cost of the rope descent device is expensive, and there are still high requirements for the escape skills of the survivors

The above methods have their own disadvantages, and the functional requirements for rapid evacuation cannot be guaranteed.
