Description

The invention relates to the mining industries, namely, mine construction, and is intended to expand the vertical shafts with their monolithic concrete lining.

The aim of the invention is to increase safety and reduce the complexity of work in the workings of variable cross section.

Figure 1 shows the tunnel complex in the trunk; FIG. 2 is a section A-A in FIG. one ; on fig.Z - section bb in figure 2; figure 4 - section bb In figure 2; figure 5 is a section of GT in figure 2; figure 6 - node I in figure 1; figure 7 is a view along arrow D of figure 6; on Fig section EE in figure 1, figure 9 - node II in figure 8; in FIG. 10, node III in FIG.

The tunnel complex includes the main (upper) multi-storey shelves 1. The additional multi-storey shelves 2, located inside the formwork 3. The shelves 1 are suspended on the rope 4 and have a spacer 5 and fenced openings 6.

Suspended shelves 1 are provided at the bottom with a circular monorail 7 for a rotator 8 and movably connected with it by means of telescopic vertical elements 9 of the trailed additional shelf 2, in which the bottom-hole bottom floor 10 is equipped with a safety fence 11 and can be equipped with

flap 12 over the entire cross-section of the flap to enable it to perform various works in the bottom of the trunk and retractable extension fingers (position fixtures) 13 for rigidly fixing the floor 10 in the trunk. Middle floor. 14, shelf 2 has a cantilever-extendable platform 15, which is extended beyond the contour of floor 14 into openings formed as a result of the deflection of the trunk rising from the vertical axis to perform the necessary tunneling works.

The design of the complex allows the shelf 2 to rotate, which allows the angular displacement of the void surpluses in the trunk to combine the axis of the advanced platform 15 with the direction of the location of the voids. At one end of the platform 15, support rollers 16 are mounted, which roll along guide rails 17 mounted on floor 14, the opposite end of platform 15 rests with its rails 18 on rollers 19 mounted directly on floor 14. Platform 15 is fixed in its original or extended position clamping screws 20 to floor 14.

The hitch is made in the form of rigidly mounted on mounts 21 formwork 3 guide sockets 22 with stops 23 and hanging brackets 24, the lower part of which is made in the form of a hook, and the top part - in the form of a curvilinear guide interacting with the descent or ascent of the shelf 1 s hinged on racks 25, shelf 1, earrings 26 with crossbars 27, spring-loaded in angular displacement and with the possibility of fixation at an angle of rotation of at least a c, using clamps 28, mounted on racks 25, shelf 1 (a) the second angle at which the hooking of the shackle 26 with retainer 28 can occur.

The tunnel complex operates as follows.

In the event that a person rising beyond the bounds of the trunk section leaves during the descent of the tunnel complex to the next stop of the trailing shelves 2, the rotator 8 is rotated by the angle at which the axis of the platform 15 coincides with the direction of the search. Thereafter, a rigid mounting of the tunnel complex with spacers 5 and t3 is carried out. Then, using rollers 16 and 19, the console 15 extends the console and fixes it in the working position with the clamping screw 20 relative to the floor 14. From the platform 15, preparatory work is carried out on the design of the support ring in the cross-section of the trunk. After completion of these works, platform 15 is pushed onto floor 14, the tunnel complex is freed from thrust and, using shelf 1, the formwork 3 is lowered and installed on the support crown. Again, they unfasten and center the equipment of the complex and conduct the concrete reinforcement of the trunk support. From the bottom-hole floor 10, lowered onto the ledges of the bottom of the barrel, drilling works, drilling, hole loading, etc. are performed. The execution of the flooring in the form of sectional sashes 12 allows you to open openings only at the place of work, making it safe for people to stay outside the open sections. Before blasting, the tunnel complex is set loose and moved upwards.

0 along the trunk to ensure the safety of equipment and people. When this occurs, the automatic disengagement of the regiment 1 with formwork 3 as follows. Shelves 1 lowered, cross member 27 earrings 26 at

5, moving along the curved guide bracket 24, turning, removes the link 26 from engagement with the hook of the bracket 24 and with the help of the clamp 28 keeps the link 14 of the shelf from engaging with the formwork. At this time, the shelves 1 are raised to the height required by the safety conditions. After blasting, the tunnel complex is lowered and the formwork 3 is automatically connected to the suspended regiment 1 in the reverse order of the above.

When lowering shelf 1, earring 26 with its lower arc enters socket 22 and is thus centered relative to

0 splints. The separation of the formwork 3 from the concrete lead by lifting the shelf 1 to its free suspension on the earrings 26.

Then formwork 3 and bottom-hole bottom floor of shelf 2 are installed on new ones

5 stoppages. When installing the bottom-hole floor 10 on the ledges of the bottom of the barrel, a complex is set up by telescopingly connecting the vertical elements 9 with the frame of the shelf 1.
