Description

one

The invention relates to land and underground rail transport, and more specifically to rail transport of open and underground mining enterprises,

A known transport system comprising a trolley comprising a body mounted on hrd wheels with side support lirami interacting at the place of unloading with supporting rollers and a movable head hinged to the body, track rails installed before and after the place of unloading, and a guide beam mounted in the discharge area 1.

A disadvantage of the known construction is the smooth opening of the bottom, which leads to a gradual sliding of the load over the surface of the bottom and the walls of the body, as well as to the closure of large pieces of cargo in the gradually increasing exhaust rtpoeMe. In this case, the bottom and the walls of the body are subject to intensive wear, especially when unloading large-scale abrasive goods, and the discharge capacity is limited by the slow speed of movement of the cargo.

Another disadvantage of the known construction is the large extent of the unloading area due to the device of smooth lowering and raising of the bottom and the presence of bottom movements due to uneven support of the driving wheels on the guide rail.

The purpose of the invention is to increase the efficiency of discharge and preservation

to trolleys.

The goal is achieved by the fact that the movable bottom consists of two flaps, the front of which overlaps the rear one with the follow-up rollers attached to

by means of brackets and contacting with support beams mounted at the place of unloading, each valve is connected to the body by means of a kinematic connection, including a cylinder with a rod installed in the working tank, provided with parallel-installed throttle and reverse valve, and the rails at the end unloading section have an inclined section towards the discharge.

The throttling cross section of the front flap may be larger than

30 back. Ha FIG. 1 shows the proposed system, a general view; in fig. 2 - the same at the beginning of unloading; in fig. 3 the same at the end of the discharge; in FIG. 4, section A-A in FIG. one; in FIG. 5, node T in FIG. 3. The transport system includes a trolley- 1, supporting rollers 2, support beams 3, track rails 4, side guiding beams 5 and a discharge mu 6. At the same time, each trolley 1 has a body 7 with side support skis 8, a front 9 and a rear 10 bottom flaps hinged to the end walls of the lower part of the body 7. Brackets 11 are installed on the lateral surface of the flaps .9 and 10 with following rollers 12 and the running wheels 13 are installed on the lower surface of the flaps 9 and 10. Each flap.9 and 10 of the bottom of the carriage 1 connected -. body 7 by means of a kinematic connection, comprising a rod 14 with a cylinder 15, mounted in the working tank 16 and having a connection between the working cavity of the cylinder 15 and the tank 16 by means of parallel-installed non-return valve 17 and throttles 18. The supporting beams 3 are interrupted in the discharge zone we b and rails 4 in ЖбйЭ; ® Раз р§з6чй6йми 6 6 inclined section 19 towards the discharge side and the lateral guide beams 5 .. The transport system works as follows. When the trolleys 1 move towards the unloading side, side support skis 8 of the body 7 roll onto the support rollers 2, and the following rollers 12 roll onto the support beams 3. Before unloading my arms, the rail 4 is interrupted and independent support of the body 7 is created on the support rollers 2 by means of side support skis 8, and folds 9 and 10 of the BOTTOM onto the support beams 3 by means of brackets 11 and followers, 12. & the unloading zone 6, the support baiJi ki 3 is interrupted, and in the moving trolley 1, the rollers 12 of the front flap 9 are released from the support to the support beam 3 and the load is transferred from the front flap, 9 to the rear flap 10 in the area of their flip-open. When the end section of the support beam 3 passes by the rollers 12 of the rear flap 10, simultaneous clearance from the bearing 9 and 10 of the bottom of the trolley 1 occurs. Since the follower rollers 12 are installed by means of the brackets 11 beyond the lateral dimensions of the leaf 9, the latter can move in the clearance between the support beams 3. Under the action of its own weight and weight, the flaps 9 and 10 simultaneously open and

Simultaneously with the opening of the valves 9 and 10, the rod 14 moves in the cylinder 15, from the working cavity of which, through the reverse clutch, the pan 17 and the throttle 18, the air passes to the tank 16. At the same time, the dynamic loads acting the flaps 9 and 10 and the body 7, as well as the accumulation of energy in the form of an increase in the air pressure in the tank 16. After the cargo has been removed from the cargo, the flaps 9 and 10 of the bottom are gradually closed under the action of compressed air passing through the throttle 18 into the cylinder cavity 15. At the same time, the increase in the throttle cross section. 18 in front of the hinge 9 compared to the throttle 18 of the rear flap 10 allows for the initial closing of the leaf 9 and then the flap 10. At the end of the unloading we 6, the running wheels 13 of the trolley 1 are oriented in the horizontal position using the lateral guide beams 5, and in the vertical flatness using the inclined section 19 of the track rails 4. In connection with the fact that the transport system enables the simultaneous and quick opening of the bottom flaps over the entire area of the body bottom, freedoms occur This means that the load falls out and thus creates conditions for the fast unloading of the trolleys with a negligible effect of the load on the cusps of the bottom and the body wall. Due to this, there is an increase in the productivity of train unloading, a reduction in the length of the unloading station and a decrease in wear of the walls and bottom, especially when unloading lumpy and abrasive goods. Claim 1. Transport system, mainly for quarrying, comprising a trolley including a body mounted on the running wheels with side support skis interacting at the unloading site with supporting rollers and a movable head hinged to the body, track rails mounted up to and after the place of unloading and the guide beam, mounted in the unloading zone, is necessary so that, in order to increase the efficiency of unloading and preservation of the trolley, the movable bottom with It consists of two wings, the front of which overlaps the rear, equipped with followers, attached to them by means of brackets and in contact with support beams mounted at the unloading site, each valve being connected to the body by means of a kinematic connection, including a cylinder with a rod installed in the working tank, provided with a parallel-installed throttle and non-return valve, and the track rails at the end of the unloading section have an inclined section towards the unloading side narrow. 2. The system according to claim 1, about tl and h ayu (t and the fact that the throughput cross section throttle front flap more than the back.
