Description

The invention relates to rescue devices and can be used to rescue and evacuate people in case of fire.

A rescue device is known, made in the form of an evacuation elastic hose with holes — windows installed on a rigid stationary multilevel frame frame for simultaneous evacuation from different levels of a building.

The disadvantages of this device are high inertia when installed in the working position; rigid fixing of the holes — windows in height, which complicates its use for evacuating people and cargo from uneven and unevenly arranged vertically equipment service platforms in the process shops; the danger of a fall-down of people and cargo through the internal cavity of an evacuation elastic hose that does not have horizontal platforms.

The closest in technical essence to the present invention is a scaffolding device comprising horizontal frame frames with platforms which are provided with side evacuation apertures and in the initial position of the device are adjacent to each other. To fold into an adjacent initial position and extend their height relative to each other by equal distances, these frame frames are hinged on them with reinforced rigid lever linkages of the type of pantograph, which are driven by an external power drive,

The disadvantages of this device include the high inertia of the installation to its original position with the help of a power screw low-speed self-braking nodular drive; availability of additional features

th source of actuation; the simultaneous advancement of all frame frames with equal intervals between them in height, which creates difficulties and danger of evacuation in case of unequal arrangement of equipment maintenance sites and by evacuation.

The aim of the invention is to increase the speed and the expansion of tactical possibilities when installing the rescue device in the working position without an additional external source of energy.

This goal is achieved by the fact that the rescue device contains a package located one above the other and connected by supporting pillars solid along the contour frame frames with platforms fixed on them with side evacuation elements, the sliding supporting pillars are made of an elastic material with an arcuate cross section C-shaped stoppers that interact with adjacent platforms containing frame frames.

FIG. 1 - 3 schematically shows a rescue device.

Elastic platforms in the form of diaphragm catchers 2 with varying degrees of elasticity are strengthened on the frame frames 1 closed along the contour. The elasticity of the diaphragm-catcher of the upper frame frame is greatest, and the lower one - the smallest. The frames 1 are interconnected by sliding support struts in the form of elastically -.- deformable elements 3, which are fixed on the frames evenly along the perimeter. In the assembled state of the proposed rescue device, the frame frames 1 are adjacent: to each other by blocking stops 4, which restrain the forces of elastic deformation of the elements 3. The blocking stops 4 hold the frame frames 1, being located in an adjacent-pair sequence, each frame is adjacent to an adjacent frame, and each pair of frame frames adjoins an adjacent pair of these frames (Fig. 1). Along the perimeter of the frame frames 1, the ring stoppers 4 can be installed uniformly or concentrated in the region of one of the elastically deformable elements 3, (1 - 3). The elastic diaphragm catchers 2 are equipped with side evacuation holes 5, the edges of which are interconnected by cable ladders or rescue hoses, as shown in FIG. 2 and 3.

The rescue device is used as follows.

Upon arrival at the site of a fire or accident, the operational unit lays down the rescue device at the base of a burning or damaged structure (Fig. 1), then, removing the required number of ring stoppers, adjusts the height of the rescue device so as to ensure complete and safe evacuation of people from dangerous areas (Figs, 2 and 3, the direction of the arrow e). When removing the ring stoppers, the elastically deformable elements 3, which are folded in, are released. When dispersed, the elements 3 form vertical rigid legs holding frame frames 1 with platforms in the form of diaphragm catchers 2. Presence of 2 side evacuation holes in the diaphragm catchers 2 5, the edges of which are interconnected by cable ladders or rescue sleeves 6, makes it possible to receive evacuees from any level within the overall height of the rescue device (Fig. 2). The place of installation of the ring stoppers 4 along the perimeter of the frame frames 1 can be installed on the inclined surfaces (Fig. 3).

After application, the rescue device is assembled to its original condition, the frame frames 1 close by bending the elements 3 with a transverse force and then installing the blocking stops 4, starting with the lower apart pair of frames. The assembled rescue device is placed in a storage place or taken away on auxiliary or special equipment of operational fire departments.

The proposed device is resistant to vertical dynamic loads due to the fact that the elastic deformable elements have a profile with an arcuate cross-section, which, straightening, forms vertical support legs that are longitudinally resistant to loads. Elastic tissue diaphragms, catchers of varying degrees of elasticity, decreasing from the upper diaphragm to the lower, effectively and smoothly absorb the kinetic energy of a falling human body, preventing re-tossing. The presence of lateral openings in the diaphragm catchers and the presence of passing rope ladders or rescue arms passing through these openings allows uniform evacuation of people from different height structures, lifting and transport and technological equipment.

The proposed rescue device is conveniently transported on auxiliary or special equipment of operational fire departments, quickly installed in a working position, simple and reliable in operation, has enhanced tactical capabilities in comparison with the prototype.
