The Vrub Rope Machine (Fig. 1-3) consists of a main frame 1 with shoes attached to it. The lifting screws 2 are fastened to the main frame, and the chain rollers 54, which serve to lift the upper moving part of the machine, are threaded.

The upper part of the machine consists of massive steel wheels 3 and 4, on the sides of which there are legs with holes for threaded bushings of the chain rollers 54. Between the legs of the circles, 3-4 tons of chain lifting rollers are supplied with ribs.

Inside circles 3 and 4 there are turning circles of 5-6 with massive flanges, as if embracing outside circles 3 and 4. On the outside of turning circles 5 and 6, ratchet wheels 7-7 are attached. Inner (15)

The turning circles 5-6 are connected by channels 8 around the ribs of the ethnh circles. The channels connecting the turntables 5-6 are strengthened by means of circular sectors, motor 3J and gearbox 32. To inner circles 5-6; . bolts with countersunk heads or grouse fasteners, bearings of the rotary frame 9-10 are fixed.

The pivoting frame serves to align the crust 33 of the spike 33 with the plane of the guide roller 15 of the lower branch of the rope when cutting the cut.

The swinging frame (phi: 1, 2, 3; 16 ,. 17, G6) consists of two steel bends 34, 35, terminated by shafts, which sit in bearings 9-10 of turntables. Both in the upper part and in the lower knee can be connected with channels. On the upper part of the frame is mounted an insertion device consisting of two tension screws U, which are included in their bearings in the bearing 12-12 and two supporting shaft 19-19. In the lower part of the pivoting frame, it is reinforced with bearings 16, transmitting the rotational movement of the pulley from the gearbox 32 through a series of cylindrical gears, a screw 36 and a worm gear 37.

Due to the cylindrical gear 75, planted loosely on the axis of the kohena raya 34, as well as the feces 16 with a groove for the worm 36 key, the rotational movement of the pulley 33 does not depend on its position both along the length of the tensioning device and when its plane is aligned with the plane of the lower guide roller 15. When the plane of the pulley 33 is aligned with the plane of the roller 15, the upper guide roller 13 follows the pulley 33, remaining parallel to itself all the time. This is achieved by a hinged arallogram; one link of which

rigidly connected with the axis of the swing frame and the poem has the same turning axis with it. In this way, simultaneous co-imemeHHe of the plane of the pulley and the upper guide roller, i.e., the approach of the upper branch of the rope to the lower, is achieved. To perform this operation, there is a screw 25 with two nuts 26, 27, one of which is with the right and the other with a left-hand thread. The nuts are directly connected by a chain with a swing frame. When the screw 25 is rotated, the peaks 26, 27 are moved along the screw and thus rotate (Figs. 19-22).

Both in the upper and in the lower front joints of the parallelogram there are openings of 100-150 L.M. For free passage of the rope with the cutters. The axis of the frame coincides with the axis of the rope of the lower branch and the axis of the upper hinge with the axis of the upper branch. The axle oscillation for different rope thicknesses does not affect the operation of the machine, because both the upper and lower guide rollers, due to the grooves and the gaskets, can be adjusted.

The cutting tool type consists of cutters 1 and 2 (Fig. 4-7), planted on a steel rope in a sequence of 1-2-1-2 ... in increments of 0.5 m. Each of them consists of two half-disk halves 61, 47 with broadening to the center and strengthened to the rope using split cartridge 62 and two nuts with a tapered thread 63, 64. The rope itself consists of individual segments, equal in length to any number of steps of the cutter with ends embedded in a cone and filled with lead. Both lengthening and shortening it as necessary is carried out quickly using a lock (Fig.) Consisting of a nut 45 and a split cartridge 46.

Due to the significant pulling force (up to 1.6 /) and other considerations, a special pin has been designed. consisting of a composite rim 57 and two washers 59 with grooves for the incisors (Fig. 10-11). The washers in the inclined planes of the pulley rim are seated freely — with a gap. The rope attaches to the open shayoi and presses them in the radial direction. The shoulders of the washer slide along inclined planes formed in the composite rim ;: sheave; and tightly grab the rope. It is as if a smaller wheel is being run-in over a larger wheel, and the friction of the inclined planes of the pulley on the shoulders of the washers creates a pulling force. The design completely eliminates rope slipping over the shoulders of the washers, thus achieving a longer service life. Due to the fact that the driven pulley does not transmit any pulling force and only serves to guide the pulling rope, it is an ordinary pulley design with jacks for incisors on the rim (Fig. 13-14).

The pivoting angle is produced by a ratchet of removable handles with a ratchet handle, and the handle is fixed to the stationary turntables 3, 4; reverse rotation is prevented by the pawl 24 locking the ratchet wheel 7.

The lifting mechanism (from the gearbox) 32 consists of the drive shaft 50 (Fig. 19-22), the chain cam wheel 51, the calibrated chain 52, the tension chain rollers 53, the cam threaded rollers 54 and the lifting screws 2. The machines can be lifted by hand through the black wheel and the worm wheel, connected to the cam threaded wheel (not shown).

The feed mechanism (from the gearbox) is ssuyit on two chain choles 60 and a calibrated chain 61.

The tensioning mechanism (from the gearbox) consists of an asterisk 65, a chain Gall 66, two zvezdochochek 67, 68, connected between sooya and sitting on the axis of the frame, a chain Gall 69, which transmits the rotational motion of an asterisk 70 the screw 11, the sprocket 71 and the chain 72 are transmitted to the second tension screw 11, the latter, rotating in the bearings of the pulley 12, move it along the guide shafts 19-19 and thereby tension the rope.

The pulley rotation mechanism (from the gearbox) consists of a cylindrical gear. 74, gear 75, which sits loosely on the axis of the wheel of the frame 34 and the cylindrical gear 76, which is wedged on the shaft 16 (Fig. 22). From the shaft 16, by means of the screw 36, which sits on the sliding key, the rotational movement is transmitted to the worm wheel 37, which is wedged on the hub of the pulley 33.

/ The cutting mechanism consists of an asterisk 38, a chain of Gall 39, an asterisk 40, which is rigidly fixed on the screw 25. The latter, rotating in the nuts 26 and 27, moves them along its base line. The nuts, being connected with a swivel frame by chains 43 and 44, enveloping segments 41 and rollers 42, rotate the frame in one direction or the other.

The driver, standing at the front of the control platform, preloads the rope. The tension of the rope, both preliminary and more efficiently, is indicated by a torque spring 30. noc.:ie of how the cut is reached to a certain desired depth, the driver turns off the feed forwards and turns on the notching mechanism; at the same time, the lower rope of the rope stops and goes idle. The upper branch, having clouded additional tension, straightens and follows the guide roller. In this way, the cut layer is cut. When the incision mechanism and the lifting mechanism are switched on single-time, the lower branch of the rope is cut. Thus, the combined activation of gears will allow, to some extent, to adapt the work of the rope to the formation hypsometry.

If the mine field is cut into pillars and in front of the clearing hole there is a ramp, then the tension mechanism — one drum drum.) Caustically settles in the nearest advanced slope, thus placing it on the platform is optional.

But such cases in the practice itself do not always have and can take place, therefore the machine is designed for the more unfavorable case, t, e.; L of a slight advance by drift faces — clearing 1: th (Fig. 23). The drive platform is located on the dash gate. As already described in the description of the machine, the upper and lower branches of the rope simultaneously produce two cuttings. And through some cares determined by practice;

jepoHTHO, after 0.5-1.0 m, cantilever cuts are made in the vertical or inclined to the normal of the formation. Has handed over ;; these cuts, the rope are returned to the initial level and again continue to work along the strike.

If there are large prochs in the coal body, rock loyk or collar soil or soil, the rope can be lifted using a lifting mechanism. The ropes from the feeder are sealed for sliding metal racks or for the clinch jacks inserted into specially drilled holes in the walls of the well.

With the initial hemming of the ropes along the entire length of the iiai, the cutting of the arms is strictly cut by hand on the keel. A straight line is 20–30 cm deep, in which both branches of the rope are laid.

The steeply dropping platform with the master unit is also installed on the upper drift, and the lower one is moving on rollers along the bottom hundred of the shelves of I-pads fixed to 1 HNT racks.

The steeper the fall, the greater the height of the landing can be designed, since for the operation of the rope there are created more favorable conditions in the sense of reducing the sag. Assuming that with a fall of 70-80 °, the height of the sub-floor can be about 60-70 m.

Breaking off trimmed consoles, if necessary, is carried out with either blade jacks or jackhammers, or wedges, or bales. Can be used for undercuts in the vertical plane along the strike hand coal saws.

Cleaning of soil thickness of 10-30 cm can be done behind the conveyor. If there is an exposure from above, this operation will not be time consuming for an electric (or pneumatic) jackhammer.

Fastening drift-proofless, from the side of the removable pole.

Fastening of the clearing is usual, but as it is, it maintains the care of the cleansing face.

Collapsible Othulla cages and console extension can be applied from: natural systems.

Coal can be delivered by conventional conveyors, but it is better to use easily moving self-loading conveyors of the TNP and other (their.

The amount of shtyb (and hence it can be assumed that the amount of ditch) with a cable notch will be less than with conventional cutting machines, since the height of the slit is less than 50% of the gnaw remains in the notches.

To control the mechanisms they are up to. be connected to a sound or light CHI localization.

The development system is conventional, but for a steep fall of thick seams, it is suggested to develop horizontal or oblique layers with extension along the strike.

In view of the fact that yaschina gives mainly piece material, rather than lumpy, gas recovery per unit volume will be very small and, thus, with the existing limits on ventilation, dictated by the rules of safe mining, mining can be significantly exalted
