Bridge stacker for filling up a bulk material dump

The invention relates to a bridge spreader for filling up a bulk material dump, in particular one in cross section approximately trapezoidal dump, consisting of a bridge, which was laid on a in the HaIdenfuß area The track is moveable and the bridge girders spanning the dump and supported at the end by supports are a has the bulk material dumped on the dump storage device.

of various types, e.g. rigid storage conveyor bridges with movable Discharge belt conveyor or stacker, used which drive along a track along the stockpile and a liftable and lowerable belt boom to feed the stockpile exhibit. Portal storage devices are also known and bridge depositors, which have a storage belt on their bridge spanning the heap, which can be driven along the heap, possibly with a movable discharge and distribution belt downstream of it. the Known portal devices are occasionally also designed as combined input and output storage devices.

The high storage capacity required in most cases Due to the large cross-sections of the heaps, the heaps are extremely heavy, complex and expensive of storage devices. This is particularly true for the weaners, where the high weight of the far cantilevered webbing boom must be compensated for by a counterweight to be carried along as a dead load. Both Portal and bridge devices that are more tortuous in this regard there is in particular the disadvantage that the bulk material must be thrown from a great height onto the storage area. This leads to an often undesirable grain size reduction and not infrequently too strong dust development with considerable environmental nuisance.

The invention is primarily based on the object of providing a bridge spreader, in particular for <3as Aufschüirfcen of ülrapez-

7801141 05/13/76

heaps of large cross-sections, with which to create Throw the bulk material to be stored onto the dump from a low height of fall and without generating any significant amount of dust leaves.

This object was achieved according to the invention in that the The bridge girder can be raised and lowered together with its storage device, whereby it can be lifted on the supports is led.

In contrast to the known bridge settlers, according to the invention so the arrangement is made so that the existing of a rigid beam bridge girder together with the storage device arranged on it and can be lowered. This offers the possibility of the bulk material to be stored with the lowest possible drop height to throw the storage place or the dump, so that an undesirable grain size reduction and dust development during the storage process be avoided. The storage device arranged on the bridge girder can be of different types Be training. It preferably consists of at least one mounted on the liftable and lowerable bridge, Storage conveyor extending in the longitudinal direction of the bridge, in particular a storage belt. TJm the bulk material Distribute essentially over the entire width of the storage space and. Pile up a heap of the desired cross-section to be able to, the arrangement must be made in such a way that the bulk material fed in via the storage conveyor,

7601141 05/13/76

seen in the width of the dump, can be thrown at different places. This leaves; in various ways "accomplish. For example, the discharge can * he of the bulk material of δ em Einspeicherfördex using per se" known scrapers done. An arrangement is also advantageous in which the storage belt is followed by a distribution and discharge belt which can be moved in the longitudinal direction of the bridge and which is expediently reversible in its running direction. The bulk material supplied by the storage belt can therefore be distributed over the entire width of the pile via the distribution and discharge belt connected downstream of it. There is easily the possibility of throwing the bulk material to be stored, as is known per se, onto the dump in such a way that the greatest possible mixing and homogenizing effect is achieved.

According to the invention, there is also the possibility of using the storage device in this way or several storage belts and the like on the liftable and lowerable bridge girder to arrange that the bulk material to be stored is optional from one support or from the other support of the bridge or from both supports at the same time Bridge girders arranged storage device is supplied. This enables particularly large storage capacities reach. Furthermore, this arrangement offers the possibility of storing different bulk goods at the same time.

The supply of the bulk material to be stored to the on

7601141 05/13/76

Bridge girder arranged Sin storage device successful * expediently via a tripper car, -which the upper run of a stationary storage location belt over a belt loop so that the bulk material supplied in the upper run over the belt loop on the storage belt od.dglo of the bridge girder is thrown off. The storage bin belt can also be used to convey the from a discharge device bulk material removed from the dump can be used. With this arrangement there is at least one On the side of the liftable and lowerable bridge, one running on the track of the bridge lift and from the bridge lift Tripper cars taken along during the travel are provided. Preferably, the tripper car has on its Trolley a pivotable in the vertical plane The boom supported by the liftable and lowerable bridge, which supports the dropping and reversing drum of the tripper car wearing. The arrangement is made so that the boom of the tripper carriage of the lifting movement of the Bridge girder can follow.

According to a further essential feature of the invention is the bridge girder is pivotably mounted on the supports in the horizontal and / or vertical plane. Such storage of the liftable bridge girder allows in the event of any TJinaccuracies in the straight line of the bridge and / or inaccurate Rail laying with variable rail spacing or different height levels of the rails a corresponding one

The pivoting θ of the bridge girder relative to the supports, without that here bending and twisting forces in a bridge girder and are introduced into the supports via this. With this configuration of the bridge spreader, it can can even be used on uneven or sloping ground. There is a possibility of the rails on both sides to lay the stockpile at different heights. It is also possible to use the Einspeicher adjust the device from the horizontal position into an inclined position, if this is necessary for the implementation of the storage process or for other reasons. In the outward

Looking at this articulated mounting of the bridge girder, it is advisable to attach the bridge girder to one of the supports Support longitudinally immovable, while it is guided on the opposite support in the longitudinal direction is.

The guide of the bridge girder on the two supports is preferably designed as a slot guide, the guide slots can be provided either on the supports or at the ends of the bridge girder. For example, lets the arrangement meet in such a way that the supports each consist of two individual supports, e.g. round supports, between which the end of the bridge girder receiving guide slot is formed. The bridge girder advantageously has at one end a fork-shaped guide member, for example, which supports one of the two individual supports encompasses so that here a pivot bearing around this support

7601141 05/13/76

with simultaneous longitudinal and lateral support of the bridge girder is achieved. On the opposite side, the bridge girder can be in the slot of the bridge in both its Be guided displaceably in the longitudinal direction and in the vertical direction, expediently in such a way that it is at the same time within of the guide play Schwenkbe'wegungen in the horizontal plane and vertical plane can run.

In the case of the bridge dispenser according to the invention, each of the two is Supports via a carriage on at least one rail laid to the side of the stockpile in the stockpile base area, preferably on two parallel rails, supported and guided. It is recommended that the two carriages each to be provided with its own drive. A control device responding to the inclined position of the bridge girder can be used or the like. to control the straight running of the bridge via the travel drives. Also recommends it is a matter of arranging a separate lifting device for lifting and lowering the bridge girder on each support.

Further features of the invention emerge from the following description of the illustrated in the drawing Working examples. In the drawing show:

FIG. 5 is also a plan view which is modified in relation to the embodiment according to FIGS. 3 and 4. FIG Relocation of the bridge girder.

In the drawing, numeral 10 designates a trapezoidal cross-section stockpile bulk material, which is piled up in a storage bin bottom%. 11 On one long side of the heap 10, a stationary storage bin belt 12 is laid, via which the bulk material to be stored is fed; will.

In the stockpile base area are 10 on both sides of the stockpile two parallel rails 13 laid on which the bridge stacker 14 runs by means of driven running wheels. The bridge setter 14 is longitudinally sosLxt in l> sidsn directions Can be driven along the stockpile 10.

The bridge stacker 14 has trolleys 15 T * nd 16, which run on the rails 13 and are each provided with its own (not shown) drive. The trolleys 15 and 16 carry vertical supports 17, which in turn carry a bridge girder 18 spanning the heap 10 over its entire width. The bridge girder, which e.g. consists of a "Rigid truss is opposite the two Supports 17 can be raised and lowered in a vertical view. On

each carriage 15 »16 is a lifting device, here one Lifting winch 19 »arranged, the Vindenseil 20 over at the top Deflection rollers 21 mounted at the end of the supports 17 are deflected and attached to the relevant end of the bridge girder 18 is. By pulling out or pulling in at the same time of the two Vinden ropes 20 can thus be the bridge girder lowered in the approximately horizontal position in the direction of the storage space floor 11 or raised in the opposite direction will. If desired, the bridge girder 18 can also be inclined to the horizontal, what can be achieved by pulling in or pulling out the winch ropes differently.

A storage device is arranged on the liftable and lowerable bridge girder 18. In the embodiment shown, this consists of an infeed conveyor, here a EinspeicherbancL 22, the feed end of which is arranged at one end of the bridge girder 18 above its carriage 16, while its discharge end 24 lies in the middle area of the bridge girder. Below the storage belt 22 on the bridge girder 18 is a longitudinally movable distribution and discharge belt 25 which is reversible in the running direction and which, depending on the direction of travel, throws the bulk material to be stored either on its one turnaround 26 or on the opposite turnaround 27 onto the stockpile. With the aid of the storage conveyors 22, 25 consisting of the two belt conveyors, it is thus possible to carry ΛΛ ice on the storage area floor.

Fill up pes-shaped heap. Oa the bridge girder 18 together can be raised and lowered with the storage device, it is possible to store the bulk material with only a small amount Throwing height of fall onto the dump. It goes without saying that with increasing embankment, the heap of the bridge girders must be lifted with the storage device arranged thereon by means of the lifting devices 19. During the The bridge lifter can work with the help of the feeder of the trolleys assigned to the carriages 15 and 16 along move along the heap 10 to throw the bulk material in rows onto the heap.

The supply of the bulk material to be stored to the on The storage device arranged in the bridge girder 18 takes place, for example, by means of the stationary storage bin belt 12 with the switching on of a tripper car 28. As in particular Fig. 2 shows the tripper car has a Rails 13 running carriage 29 on which a boom 30 is supported with its lower end via a joint 31. The other end of the boom 30 is in a hinge coupled to the liftable and lowerable bridge girder 18. In the area of this end, a TJmlenk- and discharge roller 33 stored. The top belt 34- of the stationary Storage bin tape 12 is, as in Eig. 2 indicated by arrows, carried up in the tripper car and in the upper area deflected over the deflection and discharge roller 33, wherein the ein.zruspeichemde bulk material at this should 33 on the

7601141 05/13/76

Task end 23 of the storage belt 22 is dropped. Behind the deflection and discharge roller 33, the upper belt 3 ^ is returned and deflected via a deflection roller 35 into the normal horizontal course. The bulk material fed to the storage belt 22 is thrown onto the distribution and discharge belt and, depending on the direction of travel, thrown off at the turnaround 26 or 27. Since the belt 25 can be moved in the longitudinal direction of the bridge girder, the bulk material dump 10 can be built up over its entire width in this way. The pivotable in the vertical plane jib J> 0 of the conveyor belt carriage 28 is coupled via the joint 32 to the bridge girder that it can follow the lifting movement of the same while pivoting about the joint 51 on stock. In addition, de3? Tripper car 28 dragged along with the pahr movement of the bridge depositor.

From FIGS. 3 and 4, an expedient embodiment is shown for never relocating and! guiding the bridge girder 18 shown. The two standing on carriages 15 and 16 Supports consist of two spaced end supports 17 '? which, as shown in Fig. 2, appropriate at the head end at 17 "are connected. Between the two round supports 17 'on both sides of the heap is each a guide slot 36 for the engaging therein Bridge girders 18 are formed. The individual supports 17 'are designed here as fiundstützen. In the guide slots 36 the bridge girder 18 is guided in a liftable manner. At one end of the bridge girder there is a fork-shaped "PiTh-

* 7601141 05/13/76

attachment member 37 attached, which receives the individual support 17 'arranged here. The bridge girder 18 is guided -displaceably in the vertical direction via a guide member 37 on this individual support and is also supported in the direction of its longitudinal axis, the guide member receiving the individual support also forming a joint, the joint axis of which coincides with the longitudinal center axis of this individual support 17 '. As a result, the bridge girder 18 can execute pivoting movements in the horizontal plane about the longitudinal axis of the individual support 17 ^{1 encompassed by the guide member 37.} In addition, there is such play between the fork-shaped guide member 37 and the individual support 17 'assigned to it that the bridge girder 18 can also be articulated to a limited extent in the vertical plane with respect to this support.

The guide of the bridge girder 18 on the opposite side is designed as a floating bearing. The bridge girder is here in the vertical direction as well as in its longitudinal direction displaceable in the guide slot 36 between the individual supports 17 'led. Inside the in the guide slot Existing guide play, a pivoting movement of the bridge girder 18 in the horizontal plane is also possible. Besides that the bridge girder is pivotable at this end in the guide slot 36 in the vertical plane. Mt 38 are Designates wear-resistant sliding plates, which are attached at the end to the two side surfaces of the bridge girder

7601141 05/13/76

and with which the bridge girder is against the supports 17 ' can support.

According to FIG. 3, the bridge girder 18, seen in the horizontal plane, is at an angle of 90 ° with respect to the Arranged longitudinal axis of the heap. If the two carriages 15 ″ and 16 are not running precisely in synchronism, as indicated in FIG. 4, one of the two carriages advance in the direction of arrow P, the bridge girder 18 pivoting executes in the horizontal plane. The resulting changes in the distance between the two sides of the heap arranged supports are adjusted by a slight longitudinal displacement of the bridge girder balanced against the supports. When a predetermined inclination of the bridge girder is exceeded 18 comes a tactile or control element 39 into a stop against that individual support 17 'on the side of the bridge girder opposite the guide member 37 located. This sensing or control element 39 then controls the drive of the trailing or leading carriage in such a way that the synchronization is restored and the bridge girder is back in the normal position according to Fig. 3 is pivoted back.

As shown in FIGS. 3 and 4, two sensing or control elements 39 are provided at said end of the bridge girder 18, which, depending on the inclination of the bridge girder, come into abutment against the assigned support 17 'and thus the control process bring about. For the tactile or control elements known limit switches, angular incremental encoders or the like can be used. used

will. It is essential that the oblique position of the bridge girder opposite at least the support of one carriage to control the straight running of the bridge stacker is exploited.

D & the bridge girder 18 on the supports 17 of the two carriages is also pivotable in the vertical plane, it is not absolutely necessary that the rails 13 on both sides the stockpile 10 are laid at the same height level. Deviations in the height level of the rails in the course of the rail guidance can easily be compensated for without bending forces being introduced into the bridge girder. If the pairs of rails on both sides of the stockpile are not exactly laid horizontally, i.e. in the course the rail guide have a variable distance, so these irregularities can also be caused by longitudinal displacement of the bridge girder 18 relative to the support forming the floating bearing are compensated.

In Fig. 5 is a modified embodiment of the displacement and guidance of the bridge girder 18 is shown. The two carriages 15 and 16 each have only one vertical support 17, which is designed, for example, as a runner support is. The bridge girder 18 is provided at one end with a guide fork 40, which is located here Support 17 receives. This shift forms a floating bearing, in which the bridge girder 18 is displaceable in its longitudinal direction and in the longitudinal direction of the support 17 and

7601141 05/13/76

gieicli is pivotable about the longitudinal axis of the support 17 * In addition, the bridge girder 18 can execute joint movements in the 6 vertical plane. He is, moreover, s δ s two cheeks 6 guide fork 40 laterally supported. At the opposite; overlying earth, the bridge girder 18 has a

supported. The joint mobility in the vertical plane is

achieved by the existing in the guide recess 42 game. The guidance and storage of the shown in Fig. 5 3 Bridge girder 18 on the supports 17 of the two carriages therefore corresponds in its function to that according to the Figs. 3 and 4.

It goes without saying that the storage device arranged on the lifting bridge girder is of different design can be. For example, on the bridge girder 18, a substantially extending over its entire length Storage belt or some other bulk material conveyor can be arranged. The discharge of the bulk material This conveyor can be locked, e.g. by means of scrapers distributed over the length of the conveyor Create floor openings and the like. It is also possible to design the storage device in such a way that that the bulk material to be stored on the one hand from the side of the carriage 15 and on the other hand from the side of the

7601141 13.D5.76

Carriage 16 can be fed forth to the storage device of the bridge girder. In this case, two separate storage systems, for example one according to FIGS. 1 and 2, can be arranged on the bridge girder, one of which is charged with bulk material to be stored from one pile side and the other from the other pile side. Instead of the storage place "belt 12" arranged in the stockpile base area and the tripper car 28 connected to it, another conveying device can also be provided for loading the storage device arranged on the bridge girder.
