Description

Suspension platform for evacuation from multi-storey buildings (options).

The invention relates to devices for evacuating people from high-rise buildings during a fire or other emergency situations using rescue lifts.

A device for evacuating from high-rise buildings and extinguishing a fire is known, which consists of a turntable located on a vehicle on which sealed hollow sections of a cylindrical shape are installed, which are a folding inverted cup, the upper section of which is made in the form of a rescue cabin, equipped with a folding ladder with a latch in the form of a closed oval gutter, along the lateral sides of which there are hoisting paths, the bottom of the rescue cabin and the connection platform us-rope winch. (See RF patent No. 2126281, CL A62B 1/20).

The disadvantages of this device are the complexity of the design, significant time spent on deployment and limited ability to lift to the required height.

Closest to the technical nature of the claimed invention is a Suspended platform for evacuation from high-rise buildings (See application No. 2006128960 IPC A62 B 1/20 E04G 3/16 from 08/09/2006).

The disadvantages of this suspension platform are:

1. The difficulty in bringing it into working condition.

2. The lack of structural rigidity, which leads to possible vibration of the platform and causes stress in the evacuated people.

3. The elementary opportunity to improve the design.

An object of the invention is to reduce the time to bring the suspension platform into working condition and to increase the rigidity of the structure for a safer evacuation of victims.

The task is ensured by the fact that the suspension platform for evacuation from multi-storey buildings, containing a working platform with sides, is equipped with a retractable gangway with raised sides.

The invention is illustrated by drawings:

figure 1 - General view of the suspension platform in working condition (option 1);

figure 2 - General view of the suspension platform in working condition (option 2);

Telescopic construction of the first two options (due to the repeatability of common parts and assemblies is not shown in the drawing) (option 3);

figure 3 - suspension platform with a retractable ladder with folding sides and a retractable ceiling with folding sides inoperative (option 4);

figure 4 - suspended platform with a retractable ladder with folding sides and a retractable ceiling with folding sides in working condition (option 4).

The suspension platform depicted in figure 1, contains the main platform with a platform 1 and sides 2. The side located above the exit to the sliding ladder is made with a sliding door. On the sides 2, guides 8 are installed for the movement of the retractable sides 4. The guides 8 are equipped with stops (not shown).

Retractable transition ladder 3 has a narrowing at the front edge. The folding sides 5 are fixed to the sliding sides 4 on hinges 6. The fastening of the folding sides 5 at point 7 forms a pentagon arch. The sides are fastened at point 7 by already known methods. For example, a pin or two is installed on one side, bushings (rings) on the other, the pin entering the sleeve creates a rigid mount. This way the sides are fixed on trucks.

The suspension platform is as follows.

A wheeled crane, such as the Pioneer, with a lifting capacity of 1000 kg or more, with a lifting height of 70 m or more and a suspension platform are constantly on the roof. If they are not there, then on alarm the helicopter delivers them to the roof of a burning building. The hanging platform is hung on hooks and lowered by cables to a window opening or balcony, from which people are to be evacuated.

The level of the working platform 1 should be on the same level with the window sill or balcony, from which people must be evacuated. Then the transition ladder 3 with the sides 4 is pulled out. The ladder, having a narrowing at the leading edge, enters the window opening and is fixed to the window sill in the form of a hook or clip. A sliding door, made on a sliding ladder and working on the principle of a sliding wardrobe door, opens and allows access to the transitional ladder. Next, a professional lifeguard lifts the folding sides 5 on the hinges 6 and fixes them together at point 7 by meshing with each other. As a result, a stable structure is formed in the shape of a pentagon arch. The height of the arch is sufficient for a convenient transition from the burning building to the rescue platform. The evacuated people move along a rigid, steady ladder to the work platform of the suspension platform. Then a professional lifeguard disassembles the retractable structure in the reverse order from the assembly. The sides are folded, the transitional ladder 3 with the sides 4 along the guides 8 is retracted to its original position.

The sides 5 can be open. That is, they have a frame design. The frame structure is sufficient for rigidity and at the same time allows, for example, to carry out repairs under the balcony and in other inaccessible places.

Victims are delivered to a safe place (on the roof of the building or on the ground). Fire extinguishing is carried out from the same suspension platform after the evacuation of people.

In Fig.2 the same device as in Fig.1, with the following differences. The main platform has a height of human growth. The sides 4 on the retractable ladder 3 also have a height of human growth. Only one retractable side 4 is provided with a folding side 5, fastened by a hinge joint 6. The size of the folding side 5 is equal to the size of the gangway 3. Gangway 3 with sides 4 follows the shape of the main platform. After the ladder 3 with the sides 4 is extended, the additional folding board 5 rises and fastens with the side of the ladder 4. The structure becomes rigid and stable. A quadrangular corridor forms. In this case, less time is spent on assembly.

Option 3

Any of the two platforms described above has a telescopic design. That is, inside the ladder with sides there is one or more identical ladders with sides, repeating the design of the first ladder. After the first ladder with the sides is extended, the second, then the third, is pulled out of it. Folding sides are connected, and a common rigid structure is formed. Prerequisite: the front edge of the last ladder must rest on a rigid support. For example, on a windowsill in a fire or bridge support when working under a bridge.

Platforms with telescopic retractable ladders will be indispensable for evacuation from hard-to-reach places. As well as the maintenance and repair of high bridges. You can easily, quickly and conveniently inspect the bridge from the inside without risk to personnel.

Option 4

The human-height suspended platform is equipped with a retractable ladder with folding sides and a retractable ceiling with folding sides in FIG. 3 inoperative, in FIG. 4 in operational condition.

The board of the main platform above the sliding ladder is made with a sliding door. At the bottom of the platform is a retractable transition ladder 3 with folding sides 5. The transition ladder has a narrowing at the front edge and a latch (not shown). In the upper part of the platform is a retractable ceiling 9 with folding sides 10. The retractable transition ladder 3 and the retractable ceiling 9 are the same in size and are equipped with a stopper that allows you to extend to the desired distance. Folding sides 5 are fixed on hinges 6. The hinges allow the sides 5 and 10 to open only 90 °, that is, they become vertical and do not deviate to more than 90 °. Folding sides 5 are equipped with pins 11 included in the sleeve (ring) 12.

The suspension platform is as follows.

A suspension platform for evacuation from multi-storey buildings is delivered to the roof of the building by helicopter. On tall buildings (30-50 floors and above) evacuation platforms are constantly located. Extinguishing water is taken from prepared tanks in case of fire.

The level of the transitional ladder 3 should be at the same level with the window sill of the window from which people need to be evacuated. Then the transition ladder 3 and the retractable ceiling 9 are pulled out. The ladder, having a narrowing at the leading edge, enters the window opening and is fixed to the window sill in the form of a hook or clip. A sliding door, made on a sliding ladder and working on the principle of a sliding wardrobe door, opens, allowing access to the transitional ladder. Next, a professional lifeguard lifts the folding sides 5 on the ramp 3 and opens the folding sides 10 on the retractable ceiling 9. The folding sides 5 and 10 are opposite each other and are fixed with pins 11 that are included in the rings 12. As a result, a stable quadrangular corridor is formed. The height of the corridor is sufficient for a convenient transition from the burning building to the rescue platform. Evacuated people move along a hard, stable corridor to the work platform of the suspension platform. Then a professional lifeguard disassembles the retractable structure in the reverse order from the assembly. The sides are folded, the transitional ladder 3 and the retractable ceiling 9 along the guides retracts to its original position. Victims are delivered to a safe place (on the roof of the building or on the ground). Fire extinguishing is carried out from the same suspension platform after the evacuation of people.

A rescue platform is available on any floor around the perimeter of a high-rise building.

Unlike ground-based evacuation equipment, suspended rescue platforms can be installed and operate several units simultaneously at a short distance from each other to more quickly eliminate fires and evacuate people, which ground fire-fighting equipment currently used cannot afford.
