FIG.

IS 22

The invention relates to a mine rail transport, in particular to bottom-discharge trolleys and a discharge system for unloading them on the go.

The purpose of the invention is to increase the efficiency of the discharge.

FIG. 1 shows a self-unloading, and a top view of the transport system; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 2; in fig. 4 shows a section B-B in FIG. I; in fig. 5 is a view of FIG. four.

The self-unloading transport system comprises a trolley 1 consisting of body 2 with lateral support skis 3, brackets 4 pivotally connected by means of axis 5 with buffer 6. To each bracket 4 a valve 7 is attached, closing the flaps 8, and a stop 9 contacting with a latch 10, hinged on the end wall 11 of the body 2. On the axis 12 of the latch 10, the deflecting lever 13 is rigidly fixed, and wheel brackets 14 are mounted in the brackets 4.

In addition, the self-unloading transport system contains a mine car unloading device, equipped with a sliding rail line 15 mounted on beams 16 above the unloading bunker 17, each thread of which is connected by means of a lever system 18 to the drive 19. The unloading device also contains a roller path 20, interoperable with side support skis 3 of trolleys 1 and mounted on deviating supports 21 interacting with cam pins 22 pivotally mounted by means of axles 23. Bottom echo cams 22 associated with movable Shar Nirni connecting rods 24. The arms 25 are in contact with cams 22 bases diverging supports 21 which are deflected about axes 26.

In addition, the unloading device contains double shoulders levers 27, mounted on the side rail 15, hinged by means of axles 28 and connected hingedly to mobile rods 24, as well as limit switches 29 and 30 in contact with the ski 31 installed under the locomotive buffer 32. For smooth lowering and smooth rolling of the wheel pairs 14 when opening and closing the shutters 8, the discharge device is equipped at the ends of the bunker with curvilinear guides 33 and 34, and the last two (right and left in the course of unloading) sections deviating the pores 21 of the roller track 20 are provided with deflecting arcs 35.

Self-unloading transport system operates as follows.

In the initial position of the self-unloading transport system for receiving the loaded train carriage structure rail track

15 is in the shifted position (at which the distance fur: the head of the rail-rail heads is equal to the width of the track), the deviating supports 21 with the roller path 20 are in a position where the axis of rotation of the rollers is horizontal. At the approach of loaded carriages, locomotive 32 by ski 31, mounted below the buffer, hits switch 29, which turns on drive 19, which actuates lever system 18, which shifts (if for any reason has not been shifted) rail track 15 to its initial position for the passage of the locomotive. Upon further movement of the locomotive 32, hitting its side walls with the ends of the double-arm levers 27, it deflects them relative to the axes 28, thereby affecting the moving ropes 24, moving them (in Fig. 1 to the left). The hinges 24, pivotally attached to the steering knuckles 22, turn them about the axes 23 so that the shoulders 25 of the knuckles 22 rise abutting the bases of the deflecting supports 21 and deflect them with respect to the axes 26 away from the axis of the track 15. In the formed passage between the deflected supports 21 on the track 15 passes the locomotive. Following the passage of the locomotive and alternately releasing out of the side walls of the double-arm levers 27, the deviating supports 21, turning (under their weight or under the action of, for example, special springs) relative to the axes 26, take the initial position (in which the rollers of the roller track 20 ts in a horizontal position) for rolling trolleys 1 with supporting skis 3 on a roller track 20. A trolley approaching roller track 20, rolling with its deflecting lever 13 on a roller path 20, rotates the axle 12 along with rigidly fixed latch 10 on it. The latter, rejecting it, disengages from the support 9 of the bracket 4. After the locomotive, with its wheel pairs, leaves the discharge hopper 17 (and the loaded trucks are above the bunker), it pushes the end switch with the ski 31 30, the actuators 19, which act on the lever system 18, are activated, the rail track 15 is moved apart.

To facilitate the separation of the track, the trolley, when harnessed by its supporting skis 3 onto the roller track 20, is raised so that the wheelsets do not touch the rails of the track. Upon further movement of the trolley and rolling of the lateral support skis 3 on the roller path 20, the brackets 4 together with the wheel pairs 14 smoothly descend along the curved rails 33, freeing the flaps 8, which, under their weight and weight, open and the contents of the trolleys freely spill out between by rail 15. With the further movement of the unloaded trolleys and the collision with the lowered doors 8 on the deflecting arcs 35, the doors will be raised. Further closing and pressing of the shutters 8 occurs when wheel pairs 14 run over curvilinear guides 34. At the same time, the brace 4, on which the wheel pairs 14 are mounted, when rotating about axis 5, with its valve 7, the partially closed shutters 8 are pressed until the flaps are not tightly closed, and the deflecting abutment 9 and the latch 10 (under their weight or under the action of, for example, a special spring) will take a position at which the abutment 9 will close. After the last train of the train is unloaded, and its flaps 8 and arm 4 are closed, the locomotive pulls the ski 31 on the switch, giving the command to turn on the drives 19 acting on the lever system 18, the track 5 will be shifted position).
