The invention relates to means and serves to salvation (evacuation of people from high-rise buildings in emergency situations (fire, emergency, earthquake).
Rescue operations in high-rise buildings are the following known methods:
a) using helicopters;
b) using the rescue and fire fighting vehicles;
b) using private funds;
g) by squat people from building on pneumatic rescue mats and stretch fabric (membrane).
Each method has its own scope. For example, the salvation of people using helicopters can be made in the conditions available to move the helicopter (sufficient visibility, lack EN route to various utilities, near emergency building should not be skyscrapers etc).
The use of individual means of salvation is designed for people who are physically fit, in addition in each room of the building should be personal salvation.
For salvation (evacuation) of people with high-rise buildings, the most widely used rescue machines and pneumatic mats.
For example, it is known inflatable rescue device containing chute formed of inflatable cylinders that are interconnected to prorenin the authorized material and two inflatable handrail (patent for useful model RU 109413 class. AV 1/00). This device serves for the evacuation of people from buildings of low height due to the limitation of the angle of installation of the device in a vertical plane with regard to the angle of friction and instability, which ultimately unsafe.
Also known mobile rope line to rescue people in case of fire with high-rise buildings (patent RU 2435620, CL AV 1/00).
The conveyor includes a lifting fire escape and troso-block closed system. The rope cling platform stretcher, belt, allowing you to move in space (the descent from the upper floors to the ground).
The disadvantages of this device include:
a) the complexity of the design; limited service area (the salvation of men is made specifically from one room);
b) the scattering process;
C) restriction on payload platform;
d) the inability to evacuate the people in the nearby area.
For the salvation of the people also known pneumatic rescue mats, stretch fabric (copyright certificate for invention №373006 CL A62b 1/22, ASU No. 552091 class. AV 1/00, ASU No. 1386210 class. AV 1/22, ASU No. 1729516 A1 class. AV 1/22, 1/00, patent RU 2150980 C1 CL AV 1/22, patent US 4068339 And class. AV 1/00, patent DE 3516676 A1 and others).
All these devices are "hopping" type (people with floors jump into them). With aktalnye device No. 373006, No. 1386210, No. 2150980, No. 1729518 ground (installed on the ground and jump people), and the device is no 552091 floating type (gas-filled shell is lifted and held the ropes for the required height and jumping man).
Pneumatic rescue mats are mnogoplatnye shell made of high strength synthetic materials. In working condition in the shells, with the help of remote fans, constantly maintain the specified air pressure, the excess of which is automatically reset by the valve system.
The main disadvantages of these devices is limited by the height of the squat from the point of view of security for people (some designs allow a height no higher than 3-4 floors, patent No. 552091).
Pneumatic mats allow you to save people from a height up to 20 m Interval of time between jumps is 8÷12 C.
To improve landing in some cases, the rescue device is carried out in a cascade of pillows (patent No. 1386210).
During the evacuation of people from a great height by using hopping means there is an element of risk and the likelihood of serious injury saving. It is connected with overcoming human psychological barrier (fear of heights).
Pneumatic mats are of limited use (up to ODA is divided by the height of knowledge), the elasticity of the mats has a specified amount, which is necessary to maintain the pressure by means of the fan. In addition, near the building can be small forms, fences, etc. and there is no possibility to place the Mat in the desired location, i.e. in this case, such a scheme evacuation is not suitable.
Rescue device according to the author's certificate No. 1729518 A1 class. AV 1/22, 1/00 package includes frame frames arranged one above the other, which reinforced elastic pad (membrane) in the form of a diaphragm-catching with varying degrees of elasticity.
The elasticity of the diaphragms of the upper skeleton frame the most, and the lower frame a frame is the smallest. Frames are interconnected by sliding the supporting poles in the form of elastically deformable elements with curved cross-section, which are mounted on the frames evenly along the perimeter.
Assembled frame premnote to each other and fixed collar barriers hindering the efforts of the elastic deformation of the support stands. The elastic diaphragm-catchers provided with side evacuation holes, the edges of which are connected to the cable ladder or rescue sleeves.
A disadvantage of this known device include:
a) the structural complexity in the choice of materials of the parts with the required physical and mechanical characteristics is depending on the height of the jump man its mass;
b) limiting the height of the frame construction of its stability (the unit may vary from the wind, from the fall of man, etc.);
C) the need for special mounting device to the ground;
g) instability of structures (tension of the diaphragms and their area are not regulated and if the fall of man hours bent from the forces of inertia).
Closest to the claimed object is the technical solution according to the patent RU No. 2414261 class. AV 21/00 "Mobile system for evacuation of people from high-rise buildings including car platform, which is equipped with the following equipment:
a) device with adaptations for the reception of the building and down the people;
b) a lifting mechanism aerodynamic type;
d) vertical beam, the top of which through blocks suspended on wire ropes cabin;
d) support frame to maintain the cantilever truss in the original position.
This solution has several disadvantages. The design is unstable, especially in windy weather or when the snowfall, as a device for receiving and descent of the people associated with car platform with flexible elements (cables) and kept at a certain height due to the aerodynamics, which creates a blade mechanism, and forces of aerodynamics must reg in order to vary depending on the conditions.
Console farm mobile set has the departure of a constant length, it requires the vehicle to the building for a specified distance, which is not always technically possible to perform (near the building, usually located flowerbeds, lawns, trees, ramps, fences etc).
The design is complicated to manufacture and use (manufacture blades with certain aerodynamic characteristics is possible in special plants).
Evacuation of people with this complex can be produced with only one room, for the evacuation of people from the adjacent premises of the mobile set you need to reinstall.
Efficiency is also reduced by the loss of time on the descent of the cabin with people and raising the cab to the place of the hearth, in addition, the cabin has a limited volume, which does not allow to evacuate more people in a short time.
In the present invention the task is to increase the efficiency of the process of evacuation of people from high-rise buildings through the application of new technical solutions.
This process equipment is located on the platform truck chassis and trailer included with the machine, and includes stabiliser telescopic design, mounted on retractable beams boxes.
At the ends of the racks placed n the gate levers, the arms each platform are interconnected by bridges of variable length. Moreover jumper levers located on the car platform, connected with jumper levers located on the platform of the trailer, through the device for the reception of people (membrane).
This device is made of a flexible membrane, which consists of three (minimum) shock absorbing grids having different elasticity and located one above the other. The greatest elasticity has an upper cushioning mesh, and the lowest bottom of the grid.
One of the jumper blocks swivel levers made in the form of reels wound with shock-absorbing grid, and each drum is fitted with ratchet mechanism and actuator rotation. In another block each jumper has hooks for attaching the membrane device for receiving people.
The tension of the membrane device for receiving the people in the longitudinal direction is performed by moving the trailer with the platform relative to the platform of the vehicle using the hydraulic cylinder telescopic beams, which connects the platform between them, and in the transverse direction using the rotary levers.
For lateral movement of the supporting pillars of technological equipment in relation to the longitudinal axis of the vehicle chassis and the trailer they have two identical mechanism, one of colorinterpolator on the platform of the car, and the other on the platform of the trailer, with each mechanism made in the form of fixed beams and girders of box section, in which is located the bearing rollers. On the ends of the box-section beams installed retractable support elements, with one vertical wall of the box is made in the form of a toothed rack meshing with a toothed wheel gear motor. In other words, the movement of the support pillars is using gear mechanical transmission roller guides.
Device for receiving people on the perimeter of the top grid membrane equipped with flashing lights, and size of the membrane is regulated and can reach 45÷55 m2while to the specified grid attached flexible ladder and platform of the vehicle and trailer to increase their sustainability equipped with support elements, for example, the outriggers.
The rotation of the levers supporting racks and nominate themselves racks is carried out, for example, by hydraulic cylinders. Height adjustable racks and independently from the profile of support or square (earth, asphalt), they are installed in the horizontal plane.
The invention is illustrated by drawings, where figure 1 (side view) and figure 2 (a view along arrow a figure 1, option 1) shows the operating position of the rescue of the machine; figure 3 is a section b - B figure 2; figure 4 is a view along arrows is e In figure 1; figure 5 is a view along arrow g of Fig 1; figure 6 - transport position of the machine and figure 7 is a view along arrow a figure 1 (the position of the machine when moving the support legs in the direction perpendicular to the longitudinal axis of the platform of the vehicle and the trailer, option 2).
Rescue machine for evacuation from high-rise buildings includes: vehicle 1 platform 2 and the trailer 3 platform 4 and the receiver 5 people in the form of membranes (set of shock-absorbing elastic nets) 6. On platforms 2 and 4 located equipment comprising a retractable support stand 7 (a pair of racks on the platform of the car 2) and 8 (a pair of racks on the platform of the trailer 3), the ends of which are mounted swing arms 9 and 10 and the drive rotation of the levers 11 (cylinder). The levers 9 of the uprights 7 are interconnected telescopic jumpers drum 12, with each drum set (wound) damping (elastic) grid 6, with each drum has a ratchet mechanism 13 with the turn knob 14. The reel 12 mounted one above the other in parallel.
The number of shock-absorbing nets selected three while their elasticity increases from the bottom up, i.e. the most elastic upper cushioning mesh. On the rim of the upper grid, the perimeter flashing beacons 15.
To the platform 2 of the vehicle 1 is adjacent, through the om telescopic beams 16, trailer 3 platform 4 and the anchor pull-out racks 8, which is identical to the racks 7, mounted on the platform 2 of the vehicle 1.
The levers 10 trailer 3 are also connected by a telescopic bridges 17 and provided with hooks 18 and the groove 19. To the upper portions of the levers 9 and 10 of the attached flexible ladder 20.
Legs 7 and 8 of technological equipment can move transversely, i.e. in the perpendicular direction with respect to the longitudinal axis of the platform of the vehicle and the trailer by means of two identical mechanisms 21, one of which is located on the platform 2, and the second on the platform 4. Each mechanism 21 consists of a fixed beam 22 in contact with the movable beam 23 box-section through the rollers 24, which are located in horizontal and vertical planes inside the box section. One of the vertical walls of the box beams 23 on the lower side is made in the form of a toothed rack 25 which is in contact with the toothed wheel 26, the gear motor 27. The box beam 23 is installed at least five horizontal rollers and three pairs of vertical, allowing you to ensure the reliability of the mechanism of transverse movement of the uprights 7 and 8. On the ends of the movable beam 23 is installed retractable support elements 28. To increase the vertical stability of the beam 23 has a lug 29, which groove is Alki 22.
In the transport position, the support legs 7 and 8 of the levers 9 and 10 are omitted (6).
The work of the rescue of the machine is as follows. Arriving on the scene, and considering the situation, the machine is located near the building where the accident occurred, i.e. require the evacuation of people. With the help of a hydraulic cylinder (not shown) of the telescopic beam 16 moves out of the trailer 3 to the desired length L.
Simultaneously with the moving cart 3 is the tension of the membrane (elastic cushioning mesh) 6, because one side of the mesh is attached by hooks 18 to the bridges 17 of the trailer 3 and the second end of the grid 6 is wound on the reel 12 of the levers 9 of the uprights 7 are located on the platform of the vehicle 1. Fixing cushioning mesh is performed using a ratcheting mechanism 13 (design and principle of its operation is well known). Then, in the vertical plane to throw the levers 9 and 10 with the help of hydraulic cylinders 11. Then put the outriggers 30 of the vehicle 1 and the outriggers 31 of the trailer 3.
Depending on what floor the accident occurred legs 7 and 8 of the levers 9 and 10 and nets 6 upwards, closer to the site of accident.
Each rack has an individual drive extension (not shown)that allows you to install shock-absorbing mesh 6 horizontally at any given height, regardless of the flatness of the reference area is key.
People on the instructions of the lifeguard jump on top of the grid 6 of the membrane. The grid is greatly deformed, thereby softens the blow. The deflection of the top grid (depends on the magnitude of elasticity)that people with upper mesh for secondary grid, which also extinguished kinetic energy. Finally, the average net also deforms by a small amount and communicates with the lower grid. Thus, there is a gradual damping of the kinetic energy of a man simultaneously on three grids 6, which ensures the safety of the jump.
Adjustable shock-absorbing nets 6 height allows to reduce the height of the fall of man, thereby to reduce the speed of falling, and to soften the blow in the grid.
Lateral deviation of the levers 9 and 10 can increase the area of the membrane (the area of the shock-absorbing nets 6 for landing people during evacuation. In addition, the rack 7 and 8 can slide in the direction perpendicular to the longitudinal axis of the platform 2 of the vehicle 1 and the platform 4 of the trailer 3, resulting in a device for taking people out of the building to be closer to the vertical wall of the building (Fig.7).
Extension support legs 7 and 8 with the membrane is produced through gears 25 and 26 driven by a gear motor 27, while the beam 23 is moved on the rollers 24 on the fixed beam 22. When the desired position is of the racks 7 and 8 in relation to the building of the extended supporting elements 28 (options shown in Fig.7). All this improves the stability of the machine.
The possibility of rotation of the levers 7 and 8 in the vertical plane allows the stretch shock-absorbing nets 6 across, i.e. to regulate their elasticity. The area of the shock-absorbing nets 6 device for receiving from a building of people during evacuation is adjustable depending on the height of 1 premises where the accident occurred. The area can reach 45÷55 PM working area, which can block the device with a membrane (nets), with a shift to the left and to the right from the longitudinal axis of the platform of the vehicle and trailer may reach 80÷85 m2. All this helps to reduce the risk to jumping a person from the premises of the building.
Device for receiving people membranes, consisting of three shock-absorbing nets allows to provide reliable and safe landing of the people.
Top mesh, having the greatest elasticity (elasticity) greatly dampens shock and does not contribute to the occurrence of strong fluctuations, i.e. persons under the action of reactive forces will not be kicked out of the grid.
The average grid is used for the primary mitigation impact and less elastic, i.e. more elastic than the top.
The lower grid is the least elastic and fully absorbs the kinetic energy of the fall of man.
The presence of the upper grid in its parameter flashing lights 15 ru is no more clearly focus the people during the evacuation, that is especially important in poor visibility.
Machine from the operating state is in the transport state in the following sequence. Trailer 3 removable outriggers 31 and he, with the help of hydraulic cylinder telescopic beams 16, is approaching the vehicle 1 by a given distance. Then go down the rack 7 and 8 of the levers 9 and 10, with these levers occupy a vertical position. Then use the rotary knob 14 working rotates the drum 12 and thereby winds up absorbing the grid 6, the ratchet mechanism 14 locks the drum in the desired position. And so all three grids skip out on the drums. Then we cleaned the outriggers 30 car down (take horizontal Polonia) levers 9 and 10 and rescue the machine is ready to move.
The proposed machine, compared with the prototype, quickly installed in its working position, has advanced technological capabilities and more efficient to use for evacuation of people, because it does not depends on the technical condition of the building and okolozemnoi territory (clutter on the site near the building etc).
In addition, and most importantly, significantly reduced the height of fall of persons by means of lifting devices for taking people to the required height.
Increases the safety of the landing of the people due to the large area of the membrane and drop what is the probability of emission of the people after the fall of the membrane due to the presence of three shock-absorbing elastic nets, located one above the other and having different elasticity.
