    6. The device according to PP, 1-b, O TL and - tea due to the fact that the thrust bearing is equipped with rollers on which a longitudinal frame is installed,
    7. The device on PPL-B, about t of l and - tea. The fact that the thrust bearing and the thrust device are provided with lateral rails tapering to the point of contact with the front arm. . .
    8. The device according to nn.1-7s about tl and - that the transport trolley is equipped with a side console installed with the possibility of shifting The invention relates to a device for temporary fastening a drift or a tunnel near the bottom, the production of which is done by means of a cutting machine.
    The aim of the invention is to expand the technological capabilities of the device.
     Figure 1 shows the proposed device, a side view (the contours of the cutting edge mapp-shy itself are indicated by Enpuif.- dotted line); figure 2 is a top view; Fig. 3 shows a transport view, side view (the extended position is shown by a dashed line); in fig. 4 - the same plan view; in fig. 5 is a control circuit of the Lift Mechanism,
    Vruva machine 1 has a tracked undercarriage 2. Hard p§ 3 by two pillars 4 and 5 are rigidly connected to the iron machine 1. Line 6 marks the middle of the turning mechanism for the notch bar 7, having cutting heads 8 at its protruding end. 6 is a vertical axis around which a notch can be horizontally turned.
    The axles are perpendicular to the trolley axis, and the lifting mechanism is made of two pivotally connected levers, the lower one of which is pivotally mounted on the console and is additionally connected to the console and vefnim lever by means of hydrocylines, ars, and the rod cavity of the hydraulic cylinder connected to the upper arm, communicated with the piston cavity of the hydraulic cylinder connected to the console, and their other cavities communicated respectively with the pressure and discharge of the container.
    9, The device according to claim 8, characterized in that the temporary support frame is made with an opening and a device for hanging the permanent support upper support, and the upper arm is provided with a pin for installation in the temporary support hole.

    bar 7, the latter can be rotated in a vertical direction around the horizontal axis 9.
    The front end 10 of the rigid frame 3 reaches only the middle of the turning mechanism. On the rigid frame 3, the support of the feeding mechanism 11 is mounted for movement, moving towards the face 12 from position 11, in which it does not protrude beyond the front end 10 of the rigid frame 3, into position 11 indicated by solid lines. 10 of the rigid frame 3 is installed a pair of rollers 13. At the rear end of the support of the feeding mechanism 11 there is also a pair of rollers 14 which is moved between the flanges of the U-shaped longitudinal bars of the rigid frame 3.
    The pairs of rollers 13 and 14 are not enough to accommodate the large forces acting on the support of the feeding mechanism 11, therefore a thrust bearing 15 is provided, having rollers 16. Pa the resistant bearing 15 an operative of the feeding mechanism 11 runs into parts of its progress of filing. Thrust bearing 15 is installed
    five
    at the free end of the pivot lever 17 located in the middle 6 of the pivoting mechanism 18 on the axis 19. Approximately in the middle, the drive lever 17 rests on the stop fixture 20 mounted on the socle 21 of the air bar 7. I in an approximately horizontal or downward tipped position bar 7, the drive lever 17 abuts against the stop fixture 20, so that the thrust bearing 15 senses the support of the feed mechanism 11. The contact surface 22 of the stop fixture 20 is designed as an arc of a circle, the midpoint of which is lives on the axis 9 of rotation of the notch bar 7, so that the height of the thrust bearing 15 at all positions of the notch bar 7 in the lower region remains constant.
    The drive lever 17 is made in the form of a frame, i.e. There are a pair of drive arms that are connected by a crossbar -23, therefore thrust devices 20 are provided on both sides of the notch bar 7 and two thrust bearings 15 are made on the crossbar 23, and the thrust bearing 15 interacts with each longitudinal beam 24 by means of rollers 16.
    The thrust bearing 15 is equipped with two converging guides 25 to ensure proper feeding of the support of the feeding mechanism 11. The thrust bearing 20 also has tapering lateral guides 26.
    On the support of the feeding mechanism 11, the transport trolley 28 is mounted for movement on rollers 27 carrying the lifting mechanism 29. The possible position of the transport trolley 27 with the support of the feeding mechanism taken away is shown by dashed lines, in this position it can be used to chop the temporary support frame 30 Fig. 3), has a recess 31 in which the trunnion 32 of the lifting mechanism enters 29. After the lining of the lining, the support of the feeding mechanism 11 approaches the face 12, for which a system of ropes 33 is provided, which is controlled From the winch FOR, is guided along a swivel roller 35 mounted on a rigid frame 3 and secured in part 36 on a support of the feeder 11. A second system of ropes 37 serves to retract the support
    2139914
    of the feeder 11. In the position extended to the bottom of the slab, the transport trolley 27 is shown in solid lines. In this position, the temporary support 5 frame can be installed near the bottom.
    The lifting mechanism 29 consists of two swing arms 38 and. 39. The lower rocker; the lever 38 is mounted on the axis 40 on the console 41. The upper swing lever 39 is connected to the free end of the lower swing arm 38 by means of a hinge 42 and carries a support for the trunnion 32 at its free end time frame. On the lower swing arm 39 on the axis 43, a lifting cylinder 44 is pivotally fixed, the other end of which is pivotally fixed on the axis 45 to 20 arms 41. On the upper swing lever 39 on the axis 46 a second lifting cylinder 47 is pivotally fixed, which at point 48 is fixed on the lower swinging lever 38. Using lift SMHbix cylinders 44 and 47, the swing arms 38 and 39 are extended to positions 38 and 39.
    In order to ensure the successive extension of the rocking arms 38 and p 39, the following control is provided (Fig. 5). When lifting the lifting mechanism, the piston side 49 of the lifting 1p1linder 47 is connected with a pump. The rod side 50 of the lift cylinder 47 is constantly connected via a pipe 51 to the piston side 52 of the lift cylinder 44, while the rod side 53 of the lift cylinder 44 is connected to a reservoir. Thus, the piston in lift cylinder 44 moves only depending on the movement of the piston in lift cylinder 47. When retraction, on the contrary, the rod side 53 of lift cylinder 44 is connected to the pump, and the piston side of lift cylinder 47 is connected to the reservoir.
    The console 41 is mounted on the transport carriage 27 with the possibility of lateral movement along the guides 54 and can be moved in the transverse direction by means of a hydraulic cylinder 55 in order to install the temporary support frame in the middle of the roof.
    55 On the frame 30 of the temporary support, a hook 56 is provided on the side, on which the top 57 of the remaining support can be hung. Why are these top 35
