(54) AUTOMATIC TRAIL VEHICLE HITCH

This invention relates to a mining transport and relates to devices for automatically engaging and disengaging mine trolleys. - A known automatic coupling of a rail vehicle for trolleys, comprising a housing in which a release lever, a wedge and return springs of the wedge 1 are placed in a groove. However, with this design, the automatic clutch is operated and the wedge is unreliable in the uncoupled position. When the car collides, the lever may jump out of the recess and unwanted coupling will occur. Also known automatically; a rail vehicle hitch for trolleys containing the body located in it a locking member and a power cylinder for driving the support member connected by means of a flexible pipe with an additional power cylinder, the stem of which is located beyond the size of the trance, means for interacting with the stop. located outside of the vehicle 2.: And the -1-TH of the design does not reliably lock the coupler in the disengaged state, because when the trolleys collide or overturn them in the tipper, the rods of the cylinders can move, preparing; automatic coupling to premature coupling. The purpose of the invention is to increase the reliability of the automatic coupler in the position On the buffer by preventing its coupling with the adjacent coupling. This goal is achieved by the fact that the offered coupler is provided with a locking mechanism of a locking member located in the housing of the valve, by means of a flexible pipe with an additional power cylinder. FIG. 1 shows the described automatic coupling, the locking member of which is in a position ready for engagement with the adjacent automatic coupling {section A-A of FIG. 3). The dotted line shows the position of the locking member when the coupler is locked in the unlocked state (for operation of the Pa buffer); in fig. 2 is the same, the position of the locking member at the moment of the automatic coupling in FIG. 3 - the same automatic coupling with a pull-out on the locking power cylinder, the rod of which is engaged with the disengagement lever, is at the side. This position of the locking member corresponds to the position shown in dotted line in FIG. one; in fig. 4 the arrangement of the block of additional power cylinders on the car and stops for controlling the automatic coupling, being outside the vehicle; in fig. 5 — power cylinder block in FIG. b - interaction of rods with rollers of additional power cylinders with whiters; in fig. 7 consecutive positions of rods with rollers on stops,

An automatic hitch consists of a body I with a locking member located in it, including a wedge 2, a spring 3, and a disengagement lever 4.

Inside the spring 3 is a sylog. A disconnection cylinder 5 consisting of a piston 6, a ring 7, connected rigidly with a wedge 2. The nipple 8 located on the housing 1 is connected by a channel 9 of the rotocryole cavity, force c) 5 uncoupling. The housing has an opening 10 in which the power cylinder 11 of the locking is located, consisting of the housing 12, the piston 13, the spring 14, the rod 15 with the hook 16 and the nipple 17. The block 18 of FIG. 4) of the additional power cylinders is attached to the trolley 19 on any sheet of the body that stocks stand for the size of the trolley. Block 18 has an additional locking cylinder. It consists of a cylinder: 20 (Fig. 5), a piston 21, springs 22, 1 of the stem 23 with a roll "d 24. The additional actuator-i of the declination power cylinder consists of an IE 25, a piston 26, springs 27, rod 28 with roller 29. Housing 30 of block 18 is equipped with two channels 31 and 32, terminated with gipples 33 and 34, connected in no way by flexible pipes nipples 17 of locking power cylinder 11, 8 power q; un 5 uncoupling . . :

In places where it is necessary to disconnect-block the automatic couplings, 11-shafts 37 are installed with racks 39 fixed on them using gusset plates 38, on which the stops 40 and 41 are located. The sleeper 37 is equipped with wheels 42 to reduce the swinging amplitude of the trolleys. Autocoupling-works on the board. .Anti-clutch locking in uncoupled state for paQo-eta Per buffer.

When driving a trolley through the stops 40 and 41 of the roles. 24 and 29, run 5, they are in the sequence indicated in FIG. 7, act in the same sequence on pistons 26 and 21. Compressed air formed in cylinders 25 and 20 flows through channels 32 and 31. in flexible pipes 36 and 35 and acts first on piston b, throwing it to the extreme right position (Fig. 2), then. . piston 13, lowering it to the extreme

5 lower position. At the exit from the stops 40 and 41 in the Inverse sequence, the rollers 24 and 29 are returned to their original position by the action of the springs 22 and 27 and the compressed air. The compressed air expands, the pressure drops, releasing the piston b. The spring 3, acting on the wedge 2, moves it, and with it the rod 7, the piston 6 and the disengagement lever 4

5 lev. The latter rests on the rod 15 of the lock cylinder 11. At this moment, the roller 24 slides down from the stop 40, the pressure in the additional power cylinder 20 drops, releasing the piston 13 with the pulley 15, which under the action of the spring 14 starts to move upwards. The hook 16 is hooked onto the release lever 4. Springs 14 and 3 reliably fix this position.

The automatic coupler is locked in the disengaged state and the Cha buffer can work.

In places where you need to unlock the automatic coupling, i.e. bring her

with. Reverse required when locking the coupler, i.e. first, the piston 21 is actuated, which lowers the hook 16 down, releasing it from the engagement with the lever 4. Then it actuates.

fj em piston 26, retracting the lever 4 in the right, in the DSE stop, after which the roller 24, moving down from the stop, releases the hook 16, which is lifted upwards, opening the way for the lever 4 to the left. After that, the roller 29 slides off its stop, releasing the piston 6 by reducing the pressure. Spring 3 moves it together with the lever 4 to the left and the locking member takes up its original position. Auto coupling ready for

Automatic coupler operation when coupling cars.

When an automatic coupling collides, a wedge 2 of one automatic coupling acts on

5 the same wedge of the other automatic coupling, both wedges are set, compressing

spring 3 and moving the pistons 6. The protrusion of each automatic coupling enters the corresponding shed of another automatic coupling. The wedge 2 is squeezed by the springs 3 and the coupled state of the coupler is fixed.

Automatic coupling lock.

Sometimes there is a need to disconnect the trolley manually. To do this, it is enough to move the disengagement lever 4 to the right, and the wedge 2 releases the automatic lug. To manually lock the automatic coupler in the disengaged state, it is necessary to retract lever 4 to the right until it stops and press the roller 24, try to drown the rod 23, then first remove the lever 4 and then the roller.
