Description

Chain conveyor for horizontal and vertical conveying The previous means of transport that were used for shaft conveyance in lignite mining were: rack conveyance, container conveyance or bucket elevator systems.

IniTebau were either long chain tracks leading up to a certain Slope of the roadway are usable, used, or it was done by excavators or Goods extracted from larger clearing machines were carried away by special small railways and when delivering the goods to higher-lying drainage points, elevators are used, where then mostly a reloading for the purpose of onward transport by chain rail took place.

In hard coal mining, where the hard coal is raised from the lawn hanging bank higher hanging benches, e.g. B. at washes, must be brought or where mountains and coal are carried off to high heaps, wide-span conveyor bridges are used with $ ettenbahnen, steep cable cars that pull up every single car, or also elevators.

Apart from the chain railways and small railways in open-cast mines, which do not allow vertical or steeply inclined conveyance at all, all these types of conveyance require that each wagon is brought to the destination by manual repositioning once or several times, so that the one on the bottom of the pit abandoned wagons can only reach their destination with the expenditure of numerous service teams, large losses of time, cumbersome, space-consuming systems and have to cover the same conveying path the other way round. A direct, uninterrupted transport in the case of shaft conveyance or deeper lying verticals. Mining sites in opencast mining is not possible, so that the above auxiliary devices must come into action here. to order transports from @ va4ge one after the other to enable right to vertical conveying paths.

There are now devices are already known that allow continuous transports of. To make vessels on chains, the conveying paths of which are both vertical run like a whale. It is Z. B. a conveyor system is known in which the bucket hangs freely between two ropes and in which the container is hung by hand in the vertical shaft and is also suspended on the upper floors. An automatic closing of horizontal to vertical path in the shaft as well as an automatic process on horizontal The train on the upper floors is not possible.

In a further such conveying device, a platform for receiving the conveying vessels hangs between two ropes. Each individual carriage is transferred to the platform during the vertical run by means of special, rather intricate feed devices. An uninterrupted, even inflow of the conveying vessels and such a drain on the. upper floors is also not possible. Finally, an arrangement is known in which a vessel attached to two chains is, both for whale-sized as well as vertical ones This means that conveying paths are always more forest-oriented The situation remains that various auxiliary chains are used to support the vessel, the latter migrating from one auxiliary chain to the other for support.

The object of the invention is now to create a simple type of conveyance that allows the trolley to be conveyed by means of a chain conveyor from the bottom of the pit over the day without having to reload the trolleys, regardless of whether the conveying path is used after- each other in horizontal, vertical or runs obliquely.

Combine conveyor cage, chain conveyor, elevator, feed and discharge station in this = innovation, since the wagons, at the Aufg -bestelle on the pit floor Lined up randomly by the tractor, automatically in a quiet, uninterrupted manner Wise start their 1iörderweg to roll automatically on the corridor or on the hanging bench, without the need for any other assistants. -At the new conveyor system four chains are used, between which platforms at regular intervals. to hang the trolley.

These platforms remain in all as a result of the arrangement described below Positions, be it with a vertical oller wa # g @ e- right chain run, always in a more horizontal position Location as long as they are in contact with the car.

In the case of shaft conveyance, the guide frame is in the vertical shaft expediently omitted so that the chains float freely with the car. It will A continuous guide rail is attached to prevent the load from swaying.

In the opencast mine, the vertical guide is given a: closed scaffolding, similar to that of freight elevators.

Fig. I shows the overall arrangement of such a system in an open-cast mine.

Fig. Z shows part of the side view, which depends on the amount of Promotion in several adjacent scaffolds can exist.

Fig. 3 shows the main drive of the chains, Fig. Q. the platform in the view from above, Fig. 5 the same in side view.

The gripper disks a for the two load chains II sit firmly on the countershaft c (Fig. i and 3).

The chain wheels b for the chains T that are always on the outside sit loosely on the shaft 4: They are loosely arranged because the chains I and II have the same speed, but the chain wheels a and b have different diameters. However, this only applies to smaller systems, e.g. B. in the form of the patent drawing, where the main support chain II consists of a link chain, but the chain I consists of a simple anchor chain.

With heavy loads and deep shafts, where both chains I and II are designed as long-link articulated chains and both have to carry the same Lasst, both gripper disks a and b are firmly connected to the motor shaft c.

The chains II should be around 2/3 of the total load for smaller systems wear the chains I only about 1/3. The gripper disks have a, so the main load to cope with the whole operation, while the sprockets b essentially only serve as chain guides.

Since the platforms d_ form a connection between the chains I and II, the chains I are replaced by the chains II in dragged along the horizontal conveying path. One of the two gripper disks a is adjustable by itself and is fixed by the pawl e so that readjustment can take place at any time (Fig. 3).

The platforms d run, when they are not floating freely, by means of the Rollers f on guard rails g (Fig. D. And 5).

On the discharge bridge (Fig. I) the rolling trolley runs onto the to Rail h leading to the destination and is fed back to the shaft after emptying.

The platforms d have drivers i on both sides, to which support the carriages (fig. 3, q. and 5).

The process of extraction is as follows: Be on the bottom of the pit approached the full wagons and supported themselves on a movable stop q (Fig. i).

On the four chain rollers k the increasing Coming platform d in a horizontal position on the upper edge of the bottom of the pit, the stop q switches itself off - automatically or by hand - the carriage rolls forward a bit, the platform sliding under the carriage and the driver i holding it in place.

The platform d slides across the floor over the four guide rollers m, with the carriage running on rails h on a slope, while the platform pivots empty between the panes a and b and on return to the shaft picks up the carriage returning on a slight slope. The four guide rollers n guide the platforms and carriages evenly back into -the- .schacht, while each carriage after @ -, i.e., passing the. four guide rollers o runs down the slope on the shaft bottom, the empty platform d swivels around the four larger deflection rollers p and when stepping out from under the floor on the guide rollers k takes the next car with it.

The speed of the chains should be about 0.2 m [sec. amount to the Distance between the platforms 3 to 5 m, depending on the depth: of the shaft.

Heads of up to 100 m are expected.

The platforms can also be used to transport heavy goods, from Trucks as well as trucks and passenger cars are used, with one Continuous operations would be disregarded as the long platforms pivot can not make. A motor vehicle z. B. would be on the lower part drive onto the immovable platform and after reaching the upper unloading point depart from the holding platform, which is returning the same way as it has come.
