    Designation: Large-wheeled wheeled excavator with telescopic bridge and portal-like loading system directly above the conveyor belt 5
    description
    The invention relates to a large bucket wheel excavator with telescopic bridge and portal-like loading system directly above the Strossenband. As a result, 10 is saved over all previous versions, a conveyor belt.
    Large-capacity wheeled excavators have been built for over 50 years with telescopic bridge and loading system. This combination has the advantage that all material transfers are always centered and when stepping forward and backward 15 of the bucket wheel excavator in operation no larger
    Material quantities can fall on the planum. The telescopic bridge also makes it possible that during normal block mining only the dredge system moves back and forth, while the loading system can remain at the same place for a long time. 20 As early as the 1950s, large-wheel excavators were involved
    Built intermediate bridge and loading system. Such a device is known from RASPER, "The bucket wheel excavator as a recovery device", TRANS TECH PUBLICATIONS, 1st edition, 1973, page 73, top picture in 2 views. With the loading system, the dredged material was first handed over to 25 railway wagons and later to conveyor systems. The
    The intermediate bridge here still has a constant length and is longitudinally displaceable in the central part of the bucket wheel excavator rotating with the bridge. Later, the large bucket wheel excavators were equipped with a short intermediate belt, which conveys the material laterally out of the substructure. 30 The bridge can be supported laterally.
    Further conveying to the conveyor belt system has been developed differently in Europe East and West. -2- 4 -2- 4 • · • ······································· * · ··············································································································································································································· Such a device is from KURTH: Series Conveyor Technology, band opencast mining equipment and universal excavator, Verlag Technik 6 Berlin, 1971, page 142, Figure 3.72. "Bucket wheel excavator SRs 2400.36 / 10.0 with loading device" known. At the end of the bridge, a swivel belt is connected, which gives up the material via a hopper car on the Strossenbandanlage. The hopper wagon requires 2 rails and makes the back of the belt difficult. In this embodiment, the 10 movements of the bucket wheel excavator must be partially corrected by adjusting the swivel belt.
    In the former Federal Republic of Germany, a connecting bridge with a telescope has been used, which is supported on the one hand on the side of the substructure of the bucket wheel excavator and on the other hand on a loading system 15 (FIG. 1). The loading system moves next to the conveyor belt. A short loading conveyor with feed feeds the material onto the conveyor belt via an attached loading chute. Since no hopper car is needed here, only one rear rail is required on the belt system. This facilitates the strap back. At the loading plant no corrections have to be made when only the dredger system is moving. All differences are compensated by the telescope.
    In all previous large bucket wheel excavators, the intermediate conveyor belt, which conveys the material laterally out of the substructure, is relatively short. In all previous Großschaufelradbaggem the loading system or the 25 support car is next to the Strossenband. In all cases, another conveyor belt is required as a bridge to the conveyor belt. This conveyor belt can be swiveled as well as raised and lowered. The material is fed to the conveyor belt via a hopper trolley that can be moved on rails.
    Alternatively, the other conveyor belt is equipped with a feed and can be raised and lowered. In these cases, a loading chute for the material feed is usually coupled to the end of the strip delivery on the Strossenband. 30 -3- * «« · · ·· «· • · t · t ·« · · · · · · · # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # * · «« »* · · ·
    This has the advantage that the Strossenband only needs to be equipped with a rear rail and can be moved easily. All versions show that the loading station next to the bumpers conveyor belt with additional conveyor belt is heavy and expensive.
    The invention has for its object to develop a comparison with the state of the art cost-effective loading without additional conveyor belt to Strossenband with which the material can be passed both on a movable on rails feed hopper car, as well as an attached loading chute on the Strossenband. With the combination of bucket wheel excavator, telescopic bridge and loading system, it must be ensured that the ramps can be bridged when operating with high and low gear.
    Further details and advantages of the subject invention will become apparent from the following description and the accompanying drawings of FIG. 2, in which a preferred embodiment is shown. The drawing shows a bucket wheel excavator system in a side view and additionally the landing gear in plan view.
    The material is released from the paddle wheel 1 by pivoting the superstructure from the block and passed over a chute on the laterally arranged conveyor belt. By this conveyor belt, the material is transported via the bucket wheel boom 2 to the center of rotation, where it falls through the turntable 3 in the substructure 4. The intermediate conveyor belt 5 conveys the material out of the substructure 4 and at the same time so high that the telescopic bridge 6 can be placed on the lower disc of the substructure 4. The intermediate conveyor belt 5 is longer than in all previous versions and has a larger discharge height. Both are important in this concept, because the discharge point of the telescopic bridge is located on the Strossenband far from the center of rotation of the excavator and because the discharge height of the loading system is relatively low because of the lack of a transfer. -4- • t • · • #
    Because of the highly eccentrically mounted telescopic bridge 6, the three chassis groups of the excavator are arranged differently than before. The control caterpillar groups 7 arranged one behind the other are only a little to the left of the pivoting center. The non-controllable caterpillar group 8 is shifted far to the right in the direction of the bridge support. The arrangement of the control crawlers 7 close to the center of rotation has a great advantage in terms of the excavator propulsion in the individual terraces. The arrangement of the group of compacts near the bridge support reduces the bending moment in the substructure from the bridge load. 10
    The telescopic bridge 6 is carried out in a proven manner and supported by two roller carriage 9 centrally above the loading system 10. The length compensation takes place via a telescopic carrier 11, which rolls on rails on the one hand within the bridge and on the other hand is coupled to the loading system 10 15.
    The incoming material falls from the drop on the telescopic support 11 through the turntable 12 and the portal-like base 13 directly to a movable on rails hopper trolley or attached to a portal loading chute 14. The loading chute 14 is coupled to adjust 20 height adjustable. The loading system 10 has a portal-like base 13 with two controllable beads 15 on the side of the Strossenbandes with rear rail and a non-controllable bead 16 on the opposite side. Track control is automatically performed during the procedure with the back rail as a reference. The automatic height adjustment of the 25 feed table also uses the rear rail as reference.
    The loading system carries on the side with the two controllable caterpillars 15, the cable drum for the power supply and the e-container 17. Around the center of the portal around a Ringlaufsteg is arranged, which allows the transition to the bridge in any position.
    In the described arrangement, a conveyor belt with the associated Zustellfunktionen completely eliminated. This saves weight as well as investment and operating costs. The installation is supported by a support of the bridge on the upper side of the bridge. * * * »• · · · · Λ * ···· ··» * ··· · · »· * -5-
