Description

The proposed stopping - starting mechanism for d - lifts with two or more shaft outputs is used to set the course of the cage and any other output and to run the cage into or out of the cage, while the whole mechanism does not allow to let the cage into the cage. move so far at least. from the mine doors it remains open, does not allow also) during the course of the cage to open any of the doors, and after stopping the cage, it allows only the outside, against which the cage stopped.

In FIG. 1 and D depicts the installation of the stopping mechanism on a lift with four shaft drives, in two projections; FIG. G is the same, a partial side view (only the upper part of the lift is shown), FIG. 2, 2 and 2-component rod with round toothed racks, equipped with a flywheel and coupled with a toothed sector, carrying a lever, in three projections, With a slit of couplings and flywheel bushings, FIG. 3 and 3 locking device. for bolts of shakhtny: doors, in two projections,. 4 and 4 - a device for moving the rod from the inside of the cage in two projections, with a casing cut, FIG. 5 and 5 - stop-starting mechanism using the belt in BOJTA, in two projections.

The mechanism consists of rods 1, 2 (Fig. 1, 2), connected with the help of collapsible couplings 3 in one with the rod; on the rods x 1 of this rod there are round gear racks 5. Rod 1, 2, freely moving up and down, ce6g fixed with dowels / 4 handwheels 6, with treads, the last ones rotate in bushings of brackets 7 attached to the LuaxTbi frame; The nut 8 protects the handwheel from longitudinal movement. E1; 1I. Direction of movement of the push rod 1; 2 along its length, on the frame of the shaft, the pillars 9 with gantry rollers 10 are fastened, between which the bar passes. Per piece: ange 1, 2 by the number of outputs

the strips П, with holes 12, are reinforced, and these strips freely sit between two rings 13, which do not allow these strips. 11 move along the bar 1, 2, from the rotational

. These are held by the guides 14. Lastly, they go between two pillars 15 attached to the mine frame, so that when the rod rotates, the bars P remain in place (do not rotate with the bar), and when the bar moves 1, 2 up or down, bars 11 move with the bar as one piece. On the rod 1.2, against the intermediate outputs, in this case (Fig. 1), against the second and third, there are impactors 1.6 fixed, which can rotate together with the bolt 1, 2. In addition, against the upper and lower outputs, there are the still end drummers 17, which freely sit on the rod between two cylinders 18, prevent the strikers 17 from moving along the pole 1, 2, and from the rotational movement they are held by the uprights 19 with guide slots, so that when the rod is rotating 1, 2, end drummers 17 remain in place (do not rotate with shtanga) | and when this bar moves, the stubs move up or down with it as one. The spokes of the handwheel 6 are made projections ba (Fig. 2, 2, 2) with numbers of intermediate outputs marked on them; rotating the handwheels so that the desired number coincides with the arrow of pointer 7a, thereby substituting the drummer of the desired input, for example, the second one (Fig. 2), at the extreme outlets, as mentioned above, the impactors always stand under the impact cage, and therefore, when starting it up to these stops, the handwheel b does not rotate. Against the holes 12 (Fig. 1), with the middle position of the rod 1, 2, the bolt 20 of the hatching doors is located, the KOTOpbie can be pushed into the said apertures 12 of the way of rotating the knobs 21 of the door locks 21a, hingedly connected with the crank levers 22, the latter with its forks cover. chips 25 on bolts; located under the crossbars, of a known device, the locks 23 simultaneously with the beginning of opening the door wings, with their snaps B, enter the sockets 24 of the bolts 20 and lock them for the entire time the doors are opened; thus, bolt 20 cannot be moved with the door open and until this bolt is pushed into the hole 12 with its end, it is not possible to lift the lift cage into motion. On axis 26, located at the left end of each bolt in bearings, mounted on the frame, the levers 27 and 28 are seated (Fig. 3 and 3); the curved shoulder of the latter serves as a guide for the roller 29 mounted on the stand body 30; on the right shoulder of the hub 28 there is a counterweight 31. Approaching the desired stop, the lift cage with the roller 29 deflects the lever 28 and, at the same time, striking the lower part of the drummer, remains 1. At the same time, the roller 29 deflects the lever 28 to the maximum length and thereby removes the lever 27 sitting with it on the same axis from the slot 32 of the bolt 20. By turning the handle 21 of the door bolt, the bolt 20 slides into the hole 12, after which the shaft door is open. Passing through the intermediate stops, the cage, with its rollers, touches in turn all the levers 28 and, deflecting them, thereby removing the levers 27 from the sockets of the transomites 20 for a short time, however, opening the door will be impossible at this time. rod 1, 2 will be higher or lower than the bolt, depending on the direction of movement of the stand (hole 12 is opposite to the crossbar only during the stop of the stand). 27, being removed when the stand stops from the socket 32 of the transom, during - the course of the stand goes with its end back into this slot under the action of the load 31. To start the stand in turn, at the bottom of each exit are attached to the frame of the shaft rack 32, on which axes sectors 33 rotate. To these sectors, by means of a bolt 34, levers 35 with handles are attached. Sectors 33 have teeth, with which they engage with toothed round rails 5 rods 1.2. At the top

On the rod 1.2, there is also a rack and pinion 36, which engages with the gear 37, mounted on the axle, an oller 38. At the very end of the rod, there is another track 39, which is coupled with the toothed sector 40, mounted on one axle pugilistic core 41; a roller 42 mounted on the lever 43 of the shoe brake 44 can roll along the side / surface of the latter; this roller 42 is pressed tightly against the core 41 by means of a load 45. When the core is notched up, the brake pads clamp the brake pulley 46 and the mechanism is braked, and when the brake lever is deeply inserted, i.e. when the punching core is turned 60-90 one way or the other, the pads release the cheek and the mechanism is released. To the ends of the rod 1.2, a steel cable 47 is attached at the top and bottom, which is thrown over the rollers 48. Over the top edge of the upper door and to the bottom of the lower door, the ends of the cable are interconnected by a hinge chain 49. This chain runs vertically through the shaft and cage and to move the rod 1, 2 from inside the cage. For this purpose, inside the latter there is a gear wheel 50 (FIGS. 4 and 4) interlocking with the chain 49; To achieve better grip on the chain with the gear wheel and to prevent ek from slipping off, pressure rollers 51 are installed. . The chain 49 inside the cage from, ceiling to floor passes through the tube 54. When the cage moves, the gear wheel 50 remains constantly in engagement with the chain 49 and rotates into the idle; When the cage is started up, the handwheels are turned to inside from: 53 in one direction or another, thereby moving the rod 1.2 and starting the cage, move 6, respectively, upwards

or down. In order to facilitate the movement of the rod 1, 2, such a balance is balanced with a 54L load, securing it on a steel cable at the bottom of the shaft; in addition, the aforementioned load serves to tension the chain 49.

The lift is driven by an electric motor 55, with the help of: a) one pair of cylindrical gears 56 in an oil bath, a worm gear 57 (also in an oil bath) and a rope drum 58, mounted on a shaft of worm gear (Fig. 1; D , 1) or b); using a straight belt 59 and a cross belt 60, with a corresponding set of pulleys, at which the belt is transferred to an idler pulley by means of rail 36, segment 6-1, levers 62, b2a and conversion rod with forks 63 (Fig. 5 and 5). The rest of the mechanism consists of the last case of a gear | 57 in the gearbox 57 in the oil bath and the cable drum 58, mounted on the shaft of the worm wheel.

Instead of driving directly from the motor 55, the drive can also be carried out from the transmission.

Starting the cage during a turn is made from any stop, after all the doors are closed on the constipations, otherwise the bolt 20, being pushed into the holes 12, will not give the opportunity to move the bar 1, 2, and, therefore, to turn the cage into motion. First, rotate the handwheel b set against the pointer 7th number of the desired output, indicated on the protrusion of the spokes 6a handwheel; at the same time, the bar 1, 2 will turn and the drummer 16 will substitute the desired output for the cage. The drummers 17 of the upper and lower outlets, as already mentioned, are always under the impact of the cage. Therefore, when the lift cage is started up, the handwheel 6 is not rotated to the extreme stops. Then (if the launch takes place outside, i.e., the cage goes without a conductor), lift the lid 35 up or lower it, depending on

- 4 from the direction, the movement of the cage and, thereby, lower or raise the rod 1, 2. At this time, the round rail 36 at the top of the rod rotates the gear 3 /, -flanked on the axis of the JO controller and turns on the current, giving right or left move, i.e. the cage will move up or down. If the cage comes with a conductor, then the drummer of the desired exit is preliminarily installed, go into cage 1 and turn the handle Z1 to lock it from inside the door, after which the magician 53 located in the cage rotates; then the gear chole with 50 coupled with the chain 4U pot no bar 1, 2 and turn on the current - through the coitroller. At the same time, the toothed sector 4U with the punching core 41 will turn, lift up the lever 43 of the shoe torus 44, unlock the pulley 413, and the cage will begin to rise or touch. When the cage hits the drummer 1b or 17, it will put the rod 1 in the middle position, in which the axis of the controller turns off the motor current, and sector 40 also goes into the middle position, and the brake pads stop the pulley 4b and stand exactly against exit. In this position, the roller U, mounted on the cage housing 30, deflects the lever 28 to such a position that the lever 2 / comes out of the socket 32 and the crossbar 20 and releases the latter; then turn. By pressing the door lock handle 21, the bolt 20 is inserted into the opening of the door and the door can be opened. If the cage comes with a conductor, then after stopping the cage, it turns the handle 21 located on the inner side and freely opens the lift bar with only two shaft outlets, the rod 1, 2 is non-rotatable, since the end drummers 17 of the upper and lower ones the exit is always under the impact of the cage. In view of the fact that the bar 1, 2 does not rotate, and only the translational movement to the top and down is measured, instead of the round bars 5, 5 .., 36 and 39, flat racks are put, the need for arms must be removed. All the rest of the mechanism is similar to the above. Starting the lift cage with two ohmic outlets can be generated from the upper or lower blade after the mine belts are closed to constipation, in the opposite case, the crossbars 20, being rozunuty, as already indicated, hole 12, will not give the opportunity to move the bar 1 , 2, and, therefore, 1 to crate the cage per turn. Raising the lever 35 or lowering it, depending on the desired direction of movement of the cage, turn on the motor in the manner already described. The braking action, both when the cage is in motion and when it stops, is identical with the above-described Crate, approaches the upper or lower drummer, moves the bar 1, 2, turns off the current and stops, while the roller 29 deflects the lever 28 into such a position in which the lever 27 comes out of the crossbar socket 20 and the door can be opened. If the cage must be started up with a conductor, then, with the exception of the installation of the impactors, they act in the same way as when starting the cage of the hoist with a large number of mine exits. The subject of the patent. 1. A stopping mechanism for lifts with two or more mine exits, characterized by cumulative use, with many mine exits: a) for each of them above the mine doors - girders 20 with sockets 32, 24 and spikes 25 - for embracing their crankshaft arms 22 pivotally connected to the door handles 21, which, when rotated and the doors open, stop the cage, shift the said bolts 20, which can be closed using known

devices of locks 23 with snaps included in the aforementioned sockets 24, b) integral with circular gears 5, 36, 39 1, 2, equipped with intermediate 16 and end 17 strikers and connected with strips 11 having openings 12 for locking the rod 1, 2 beams 20 and not preventing rotation in them of the rod produced by the handwheels 6 in order to install the strikers 16 in the required positions for stopping the stand, from which the gear racks 5 of the rack engage with the toothed sectors 33 turned Levers 35 - with the whole production by displacing one of the rails 5 - move the rod 1, 2 and the rack 36, engaging the gear 37 and thereby actuate the controller 38 of the electric motor 55, and the rack 39 serves to rotate the gear sector 40 and the knuckle core 41 intended for turning loaded lever 43 and releasing the brake 46, c) shoulders 27, 28 fixed on axles connected to counterweights 31, x 26, placed in bearings attached to saddle posts, from which shoulders 27 sink into the above sockets 32, preventing the crossbars 20 from displacing and output and h with the latter — the rollers 29 of the stand, deflecting the shoulders 28 at the respective floors of the stand, and d) of the cable 47 connected to the rod 1, 2; the envelope at the top and bottom of the blocks 48 and connected to the hinge chain 49, interlocking with the gear wheel M 50 placed in the cages, which can be turned by the hand wheel 53 - in order to move the shtangi-1, 2 and actuate the electric motor 55, moreover cable 47 is secured by a counterweight 54R (FIGS. 1-4).

2. The modification, described in paragraph 1 of the mechanism, used in the case of the mine supplier only two outlets and characterized by the use of a non-revolving shtangi and only end drummers 17, where the round slats can be replaced with ordinary gear racks.
