Description

one

The invention relates to the mounting of mine shafts.

Known suspended tunnel shelves, including multi-storey frame with one movable floor bottomhole formwork and mechanisms for moving the floor and formwork.

The purpose of the invention is to simplify the production of penetration and fastening of the barrel and reduce the weight of the shelf.

This is achieved by the fact that the mechanisms for moving the regiment are made in the form of air bellows, which are connected to the floor by means of telescopic racks, and with the bottom-hole formwork — with a team of forward-facing racks in the ropes, through which the telescopic and guide racks are equipped with locks and latches,

Fig, 1 shows the predagged shelves, the view (structural diagram); Fig. 2 is a longitudinal section through the movement mechanisms.

Suspended driving ass is made in the form of a frame consisting of two

The movable floors 1 and 2 and the upper movable floor 3. The upper floor 3 is mounted for movement vertically relative to the frame and pivotally around the horizontal axis with the help of mechanisms and moves 4 through telescopic racks 5 equipped with locks 6 and clamps 7. The upper floor 3 is connected with telescopic winter stands 5 with the help of hinges 8. Bottom formwork 9 is suspended on the ropes of the South through slip-board systems llj, the drives of which are intermixed with the mechanisms 4, which are connected to the guides and 13 and clamps 14. Upper pulleys 15

the polyspast systems 11 are mounted on the guide posts 12. To secure the shelf, there are spacers 16, which can be made of a set of rubber-cord cylinders. The spacers 16 are fixed on the vertical uprights 17 J connecting the 1 st and 2 nd regiments. The shelves are suspended in the barrel on the ropes 18. On the shelf can be installed drill boring MShSHNY and other non-5 1 bypass equipment for sinking, grab 19. The pop-up works as follows. With the help of winches that are located NOT the surface of the shelves is suspended in the place of the trunk, necessary for work, on hans 18. Rjpynna drifters, occupying with sealing the shootings, installs horizontally the top floor 3 (by injecting or discharging air from the cylinder, moving mechanism 4) and using aamxj and clamps 7 fix floor 3 in the desired position. For maneuvering the bottom-hole formwork 9, the locks 6 are softened and the locks 13 are closed, which prevents the transfer of force from the transfer mechanisms 4 to the upper floor 3 through the telescopic stands 5. Thus, the force on the formwork 9 is transmitted by the polyspath system 11 through the guide posts 12 and ropes 10. Then, with the help of locks 13 and lock 14, the formwork is fixed at the required height. The use of a lightweight suspension shelf allows you to simplify the work of the staff and speed up the penetration. Claims Suspended tunneling shelves, including a multi-storey frame with one movable floor, bottom-hole formwork, we move the floor and formwork, characterized in that, in order to improve the work on the penetration and fastening of the trunk and reduce the weight of the shelf, the transfer mechanism is designed as air bellows, which are connected to the floor by means of telescopic racks, and with the bottom-hole formwork - by means of guide racks and cableways through polyspast systems, and the telescopic and railways The ike are equipped with locks and fascators. -J9 1
