Description

one

The invention relates to the field of construction and construction designed for the erection of multi-column tubular towers by the method of lifting and growing.

A device is known for erecting multi-column tubular towers using the podrash, iwatai method, which includes a bearing support, a lift, pushers with nozzles and a diaphragm. A disadvantage of the known device is that it is not possible to drive a structure from sections whose height is several times the stroke of the ram rod, which reduces labor productivity, complicates the process and does not ensure the stability of the assembly part of the structure.

The purpose of the invention is the provision of the possibility of erecting towers from sections whose height makes it possible to lift the stroke of the lift rod.

For this purpose, each pusher is made in the form of a rotary stand with a spherical support and stops that interact with a sleeve installed in the diaphragm, each sleeve being made with a turning part and an undercut.

FIG. 1 shows the device with the part of the tower being mounted; FIG. 2 - pusher, longitudinal section; in fig. 3 is a section along A-A in FIG. 2; in fig. 4 is a section along BB in FIG. 2

The device includes a carrier support 1, with which the frames 2 are rigidly connected with hydraulic jacks 3 mounted inside them, 5 of which are mounted on the rods 4, fixed from horizontal mixing in vertical U-shaped guides 6. On sliders 5 in spherical holders 7 pushers 8 are installed, the external ones are smaller than the internal ones.

diameter tubular struts 9. Pushers have a number of side stops 10, the pitch of which is equal to the course of the rods 4 of the hydraulic jacks 3. The total height of each pusher 8 is equal to the height of the racks 9.

The sleeves 11 together with the frame 12 form a movable diaphragm. Вг} locks contain a cage 13 with saddles for mounting racks 9 and turning parts 14 with grooves 15 for passing the stops 10 of the pushers 8. The sleeves 11 are enclosed by clamps 16 connected to a closed frame 12, having in the zone of each rack 9 pairs of bows 17 pockets 17, which are supported on rails 18, rigidly connected to a common support leg 1.

Between the rails 18 there are - brackets 19 with locking clamps 20. On the frames 2 there are fixed pillars 21 in the form of pairs of screws 22 - a nut 23, the screws 22 being connected to the Slider 5, and the nuts have drives synchronized with the hydraulic sleeves 3.

Moitage-Bashli: with the help of an on-line device Produced as follows.

In ISH10DN01M state, when the sliders 5 are in the lowest position, the pushers 8, which are alternately tilted from the vertical iC, are inserted into the column stands 9, which are connected with each other by welding to one another. -kami 24 and partially - spit-brass 25, forming the first Section of the Bash.n.i. Then IBO of all the sleeves. 11. The turning parts 14 are oriented in such a way that the stops 10 of the pushers 8 are opposite to the non-tilted sections and include hydrodrome-lifting 3 "and lifting. The rods 4 hydrodocs 3 push the section one step. At the same time, the nuts 23, synchronously rotated, rely on the pillars 26, VI1NTY 22 move after the sliders 5, and the BAS | MacI 17 crawls on the rails 18. After the hydraulic jack 3 is turned off, the tower is supported and rests through the sleeves 11, the sub 7 and sliders 5 on, you are 22 or hydraulic jack rods.

To rise to the next step for one of the uprights 9, the rotatable parts of the sleeve 14 EQ are removed from contact with the stops 10, turning successively not around the vertical axis until they coincide with the position of the undercut 15. Then lower the rod 4, the inapy of screws 22 and the slider 5 until the next row of stops 10 extends beyond the borders of the rotating part 14. The pusher 8 is turned again until the stops 10 exit beyond the limits of the notches 15 and this hydraulic jack 3 is set and the screws 22 are under load. All this time, the remaining hydrodoms 3 and screws 22 hold the assembled section of the lanyard with frame 12 at a new level. Oini-ica operations are successively carried out on each rack of the 9th section of the tower, after which they again lift it along with frame 12 onto the next step.

After | vystalki; vani assembly section to a predetermined height begin the installation of the subsequent section. To do this, one of the pushers 8 is completely withdrawn from the pillar 9 of the first section, deflected to the side on the stopper 7, put the pillar 9 of the next section on the pusher 8, align the pusher 8 and lift the second pillar 9 to contact the first, weld both racks. an annular seam 27. After installing in a similar manner the second II of the following racks 9, the assembly of the struts 24 and diagonals 25 begin at each next positioning post, forming the second section of the tower, which is pushed upwards. The cycle is then repeated until the tower is completed.

In the process of installation, all horizontal forces are perceived by the slider; mi 5 and through the U-Edge guides 6 and frames 2 are transmitted to the common carrier support 1.
