Description

connects to brackets 6 with the help of r 7.

The rail 5 passes through the hollow rod of the piston 8 of the hydraulic cylinder 9. All hydraulic cylinders 9 are connected by a common hydraulic system and are hinged on the consoles 4. In the upper part of the rod there are movable stops 1O, in the lower part of the hydraulic cylinder - the same stops 11, which are ledges of rail 5 during lifting and nepexBaja slats. | Q

The hydraulic cylinders 12 provide for the radial movement of the sliding arms 4, for which a tooth 13 is attached to the rod of the hydraulic cylinder 12, which, when installed, the lock 14 on the rod to the right or left | 5 from the bottom of the tooth pushes the console forward or backward.

The tabs 15 with the springs 16 provide fixation of the radially extending consoles 4 in any cross-section of the tower- 20 of the cooling tower.

Movable mounting: the scaffolding 3 is equipped with built-in brackets 17, which can be extended with the help of a winch 18 depending on the location 25 of the cooling tower fencing. Screw device; 19, made in the form of lanyard, allows you to simultaneously change the slope of the columns 20

and 21 mobile scaffolds depending

о, т slope of the cooling tower frame elements.gQ

The four-star hinge, consisting of columns 20 and 21 and beams 22 and 23, provides simultaneous inclination of columns 20 and 21 on both sides of the limiting points.

: Structures of the cooling tower tower. A telfer 24. hooked to a girder of a 23 scaffold, provides installation of rails 5 and t g 7 in preparation for lifting or fixing the ring self-lifting platform, without stopping the operation of the boom crane 2. Radially retractable consoles may not be supplied with extension (see figs, 5 and 6). In this case, to the brackets 6 on the supporting structures of the structure are fixed

| Guides 25 that can roll over rollers 26 mounted on the ends of the arms 4.

The device works as follows.

Cooling Tower Frame Mounted 50

in the usual way using ground

tower or crawler crane to the level of reachability of the hook of this crane. On

the zero mark is assembled by a ring self-lifting platform 1 with rails, a boom crane 2 and mobile scaffolding 3 are installed on the platform 55. Radial-extension sliding dowels 4 are exposed according to the diameter of the cooling tower section at the installation site

: platform1. To the brackets 6, attached- 60

using the fingers, they visit the slats 5 and 7, connected to the extendable brackets 4. When oil is supplied to the lower cavity

cylinder 9, piston 8 moves upwards; The platform 1 hangs on the rail 5 with the help of the stops 11, and the stops 10 move upward by the stroke of the piston and at the end of its stroke abut the corresponding ledges of the rail 5. Then the oil is fed into the upper cavity of the hydraulic cylinder 9, which together with the ring platform 1 moves upwards relative to piston 8, which hangs with the help of stops 1O. on rail 5; Such a step motion with interception by movable stops 1O and 11 is carried out before the platform is lifted by the amount of the platform movement, i.e., by the height of the panels of the enclosing structures of the cooling tower towers.

After climbing to the desired height, the ring platform is suspended to the brackets 6, which are located higher than it, with the help of m t 7 and hangs on them.

The radial consoles are extended to the required reach of the periodic stroke of the hydraulic cylinders 12. At the same time, the hydraulic cylinder rod, equipped with a tooth 13, during forward movement, seizes the console 4 by the notch and moves it (depending on the desired direction) forward or backward. During the return stroke, the tooth is free to bleed.

The recognition of the movement of the cantilevers 4 in this case is determined by the position of the lock 14 relative to the end of the tooth 13 on the rod of the hydraulic cylinder 12 k, thus being adjusted. The latch 15 with the spring 16 fixes the console after the end of the extension-. The rigs 7 and rails 5 are located around the circumference of the cooling tower through one, therefore, a corresponding group of radial consoles 4 is pushed without load when the platform 1 hangs, or on rails 7 or on the rails 5. After the installation of the ring platform is completed, the next elevation of the jib crane 2 and mobile platforms 3 may be included in the installation of a cooling tower. The slope of the ledgers 3 is adjusted depending on the slope of the walls of the cooling tower with a screw device 19, and the departure of the scaffolding is controlled by a winch 1

The same device can be made to install not only inside but also outside the tower of the cooling tower.

In the case when the guides 25 are attached to the brackets 6, the arms 4 are extended to the required size automatically (during lifting the ring plate,

(form 1), since the rollers 26 at the end of the radially extending arms 4, rolling along the guides 25, move these arms in the radial direction.
