Abstract

The invention relates to the construction, in particular, to devices for erecting high-rise reinforced concrete structures using a mine hoist. The purpose of the invention is to expand the operational capabilities of the device. The goal is achieved by the fact that the device is equipped with a diaphragm of rigidity 3, suspended by t g to the top of the cus 5 frame, reinforced with truss girders 32. , and is located at the level of the stiffness diaphragm 3. The working platform 27 is attached to the stiffness diaphragm 3 and to the ring truss with 9 vertical bars. Ring truss 9 has elements for fastening an annular monorail with an electric hoist. 1 hp f-ly, 5 ill.

The invention relates to the field of construction, namely, devices for the construction of high-rise reinforced concrete structures using a mine hoist.

The purpose of the invention is to expand the operational capabilities of the device.

Figure 1 shows the device, the overall view; figure 2 is a view in plan on reinforced along with the tent and the ring farm; on fig.Z - section aa 25 in figure 1; figure 4 - section bb on ig.1; FIG. 3 is a diagram of the movement of the device through the mine hoist - ck.

Device frame 1T frame 1, 30 support-cam devices 2, diaphragm 3 of rigidity, reinforcing the lower frame and suspended on flexible bars 4 to the upper frame 5 of the frame 5, tent 6, to the reinforced S end of cy 7 which is suspended on flexible bars 8 ring truss 9, support frame 10 .with drives placed on it 11, elevator equipment .12 for lifting any-. 40, blocks of trucks 13 for lifting materials, cargo screws 14, carrying out kinematic connection of the frame with the support-rear frame, guides 15 support-transfer frame of the fixed frame, ensuring its stable position during lifting. The drive 11 includes gears 16 and the motor 17 ,. The frame is supported by cam-shaped devices 2, consisting of rocker arms 18, cams 19 ,. racks 20 and springs 21, to a mine hoist 22, consisting of racks 23, girders 24 and braces 25. To the ring truss 9 on the vertical, the working platform 27 is suspended from the square rims 26. The ring truss 9 consists of ring sections 28 and 29 that have elements 30 for

fastening of the monorail 31 with an electric hoist for moving loads on the working platform. The upper c-frame 5 is reinforced by trussed beams 32 with a device 33 for pre-stressing the frame beams. The diaphragm 3 stiffness has an outer ring 34 to which the tent 6 is attached, the ring truss 9 and the inside of the working platform 27 are suspended. The ring truss is also the base of the heat cap.

Device for lifting the working platform works as follows.

The cams 19 of the uprights 20 suspended from the ends of the rocker arms 18 of the support-cam devices 2 mounted on the frame, resting on the uprights 23 of the mine hoist 22, hold the frame 1 with the working platform 27 at a given height. When the motor 17 is switched on, the movement is transmitted to the gearboxes 16, which, together with the support frame, move upwards with the load screws 14 relative to the mine hoist 22 along the guide frames 15 of the support frame for a slight step S with a slight increase. Under the fixed frame, new posts 23 are installed and connected by bolts 24 and crossbars 25 of the mine hoist. After reversing the motor 17, the support frame is lowered onto the supports. racks 23 of the mine hoist and the frame 1 is moved upward by the lifting step S with a slight increase. The supporting cams 19, meeting the obstacles, in the form of bolts 24 and diagonals 25, are deflected and, after the passage of obstacles under the action of the springs 21, return to their original position. After reversing the motor, the frame is lowered onto

supports of the racks 23 of the mine hoist, after which the cycle is repeated.

The working platform may be suspended from the elements of the outer ring of the truss 9, the middle ring of section 29, the ring 34 of the stiffening diaphragm, or depending on the diameter of the building pipe for the elements of the corresponding I ring in separate section. Unused sections of the ring can be dismantled. With small output diameters of the building pipe for the device to go down to the place of dismantling, the working site can be hung directly to the elements of the top 5 of the frame.
