Description

(54) DEVICE FOR MAINTENANCE OF BUILDINGS WHEN FIRE FIELD is installed in a vertical position. The column 2 consists of the lower section 4 installed in the supporting posts 5 of the car platform I, the upper section 6 and the intermediate sections 7. A cable 8 system is attached to one of the intermediate sections 7 and serves to ensure the stable position of the column 2. The lower ends of the cables 8 mounted on tensioning devices 9 installed on the Yu outriggers with which vehicle I. is equipped. 93 installation of tensioning devices on special vehicles (not shown), which can be installed at a considerable distance from vehicle I, which improves ychivost column 2 and provides greater mobility of the entire device. All sections of column 2 are advanced by means of cable II stored through a system of rollers 12 and 13 fixed on each section. A cap 14 is attached to the upper section 6, which has the ability to rotate about the vertical axis of the section 6. The cap is rotated by means of the tS mechanism. To The head 14 with the help of the hinge 16 is attached a horizontal console 17 supported by the cable end 18. The console 17 is equipped with guides, which with the help of the rope 19, bending around the block 20 and winding onto the barred bar 21, the cart 22 having the clips 23, in which, at one end, the guides 2 are cables. The other ends of the cables are fixed on the drums of the winch 25 mounted on the plateplate vehicle l.Ha the trolley 22 is equipped with the block 26, which bends around the rope 27, which serves to raise and lower the cabin 28. The rope 27 bends around the block, 29 passes through the inside of the column sections 2 and) fepits on the drum lifting winch ZOR. Cab 28 is complete with a door and 31 lowered by a transitional platform 32 and guides 33 in which cables 24 pass. The device is intended for maintaining the building 34, Lifting mechanism 35 serves to extend the telescopic column 2 and is mounted on the platform I, the MechanicsM 36 is intended to install the console 17 in a horizontal position. The operation of the device is carried out in the following manner. f74 In the event of a fire in a high-rise building 34, the device, mounted on a trag-sport facility I, is installed near the walls of the building, at a distance less than or equal to the console's outbreak 18. The MAZ-7310 may be used as a vehicle. The outriggers are pulled out and the platform of the vehicle I is aligned. Then, using the device 3, the telescopic column 2 is installed in a vertical position and sections 7 are pulled out by a lifting mechanism 35, and the tensioning winches 9 eject the cables 8 until the sections 7 are fully extended and fixed W T1H1M devices 9 tension guys and lock tensioning devices. When the sections 7 are extended, the winch 25 and the winder of the lifting mechanism ZO also etch the ropes, ensuring minimum tension for Bx. Then, the upper sections of the column 2 are extended to the required height and mekanizm 36 installed the console 17 in a horizontal position, fix it and turn the console 17 by the mechanism 15, set it above the building. After the cantilever 17 is installed in the desired position, the upper sections of the column are lowered, supporting the end of the cantilever to the roof of the building, which creates additional support for column 2. The rescuer rises in the cab 28 to the desired height, after which, moving the trolley 22 with a winch 21, the cab is served to the desired window opening. The rescuer fighter opens the doors 31, lets down the transitional platform 32 and enters the building, organizing the evacuation of people. When moving the carriage 22 along the cantilever 17, the winch 25 of the guided cables provides, by means of a special mechanism (for example, a torque limit clutch) constant tension of the cables 24, and when the cab 28 is fed to the building wall, the ropes are weakened, allowing the cab to be closer to the window window; The design of the device is reliable and convenient in operation. The device is universal and can be used regardless of the height of the building. Formula nzobot.en. I. A fire service device containing an outrigger vehicle. a telescopic column and a cabin with a mechanism for moving it, and for example, with one rope.

the lower ends of which are connected to the rods installed on the vehicle, characterized in that, with a chain of efficiency improvement, it has a rotatable arm mounted on the last stage of the telescopic column with a trolley on which the cab is suspended; ropes attached to the cart.

2. The device according to claim I, of gl and hr South of 8, so that the vehicle has winches installed on the outriggers, and the telescopic column is provided with cable-stayed extensions that are connected to the winches.

Claims (2)

Claim I. A device for servicing buildings in a fire, containing a vehicle with outriggers. telescopic column and cabin with a mechanism for its movement and guide ropes / 5 821397 A the lower ends of which are connected to the ba., Slaves mounted on the vehicle, characterized in that, in order to increase work efficiency, it has a pivot console mounted on the last 5 steps of the telescopic column with a trolley on which the cab is suspended while the upper ends of the guide ropes are fixed on the trolley. Yu 2. The device according to π. I, because of the fact that the vehicle has winches installed on the outriggers, and the telescopic column is equipped with cable-stayed braces that are connected to the winches and.
