Abstract

In a movable conveyor belt storage installation including a belt storage means (4), conveyor belt support structures (29) following the belt storage means (4), and a movable takeover car (7) including a deflection means (43) for the conveyor belt and a takeup chute (8) for taking over excavated material, the belt storage means (4) is comprised of at least two segments (13, 20, 22, 26) which are connected with one another so as to be pivotable about an axis extending transversely to the belt running direction and passing through the plane of the floor (31), wherein at least a portion of the support structures (29) are capable of being carried along in or on the takeover car (7).

Claims

1. A movable conveyor belt storage installation comprising

a belt storage means,

conveyor belt support structures following the belt storage means, and

a movable takeover car comprising a deflection means for a conveyor belt and a takeup chute for taking over excavated material, wherein

the belt storage means (4) is comprised of at least two segments (13, 20, 22, 26) which are connected with one another so as to be pivotable about an axis extending transversely to a conveyor belt running direction and passing through a plane of a floor (31), and

at least a portion of the support structures (29) are adaptable to being carried along in or on the takeover car (7).

2. A movable conveyor belt storage installation according to claim 1, wherein

a portion of the support structures (29) are mounted so as to be extractable along with the belt storage means (4), and

a major portion of the support structures (29) are mounted in the takeover car (7) so as to be liftable and lowerable in a height direction relative to the floor (31).

3. A belt storage means for an installation according to claim 1, wherein

the belt storage means (4) comprises a plurality of segments (13, 20, 22, 26),

at least two segments (13, 22, 26) are provided with crawler mechanisms (5),

the segments (13, 20, 22, 26) comprise frame beams (18) extending transversely to the conveyor belt running direction, and

releasable locking members (15) are provided for the pivotable connection of frame beams (18).

4. A belt storage means according to claim 3, wherein the releasable locking members (15) are comprised of pins or rods (14) which are displaceable in an axial direction in a manner as to axially immerse into, or emerge from, bearing eyes (17) mounted on bearing eye-carrying beams (21) of a neighboring segment (20).

5. A belt storage means according to claim 3, wherein at least one segment (22) comprises bearings for mounting reels (25) carrying additional conveyor belt.

6. A belt storage means according to claim 3, wherein

the segments (13, 20, 22, 26), in a box-shaped profile, each comprise traveling rails (19) for cars (23) having displaceable deflection pulleys (24) for stored conveyor belt, and wherein

the traveling rails (19) enter into mutual alignment upon locking of the locking members (15).

7. A belt storage means according to claim 3, wherein at least three segments (13, 20, 22, 26) are each equipped with at least one crawler mechanism (5).

8. A belt storage means according to claim 3, wherein

the segments (13, 20, 22, 26) each comprise two independently operable locking members (15) arranged outside a longitudinal center of the belt storage means or respective segment (13, 20, 22, 26), and

the segments (13, 20, 22, 26) are each connected with one another so as to be pivotable about a locked axis.

9. A belt storage means according to claim 3, wherein the locking members (15) are hydraulically actuatable pins (14).

10. A takeover car for an installation according to claim 1, comprising

a frame (38) and a chassis connected with the frame (38), and

a deflection pulley (43) for a conveyor belt running below a takeup chute (8), wherein

the frame (38) is configured as a portal frame (32) to articulately support at least one subframe for holding at least one of the support structures (29), a bearing of the deflection pulley (43), and the takeup chute (8).

11. A takeover car according to claim 10, wherein the subframe is suspendedly mounted on the portal frame (32).

12. A takeover car according to claim 10, wherein the subframe is connected with the portal frame (32) so as to be adjustable in a height direction relative to the portal frame (32).

13. A takeover car according to claim 10, wherein the subframe is connected with the portal frame (32) via at least two hydraulic cylinder piston units (30) and at least one further articulation (40) having at least two degrees of freedom of movement.

14. A takeover car according to claim 10, wherein the subframe comprises beams extending in a longitudinal direction of the takeover car (7) for accommodating the support structures (29).

15. A takeover car according to claim 10, wherein

a deposit for connection rods (28) for the support structures (29) is provided on the takeover car (7), and wherein

the connection rods (28) are connectable with two locking sites (46) of the support structures (29) via at least two screw bolts, which are offset in a longitudinal direction over the connection rods (28).

16. A takeover car according to claim 10, wherein the support structures (29) are mounted on the subframe via rollers so as to be displaceable in a longitudinal direction of the takeover car (7) or in a conveying direction.

17. A belt storage means for an installation according to claim 2, wherein

the belt storage means (4) comprises a plurality of segments (13, 20, 22, 26),

at least two segments (13, 22, 26) are provided with crawler mechanisms (5),

the segments (13, 20, 22, 26) comprise frame beams (18) extending transversely to the conveyor belt running direction, and

releasable locking members (15) are provided for the pivotable connection of frame beams (18).
