Abstract

A slipform paver includes a chassis 2 able to be adjusted in the heightwise direction and having a mounting unit 10 arranged on the chassis for fastening on an arrangement 8 for molding flowable material. The slipform paver is characterised in that the mounting unit 10 for fastening on the concrete mold 8 is mounted on the chassis 2 of the paver to be pivotable on an axis 14 extending in the direction of operation of the slipform paver. To produce parts of a structure whose orientation varies along their length, the concrete mold fastened 8 to the mounting unit is pivoted on the axis of pivot 14 by means of a pivoter unit 15 whereas the chassis of the paver maintains its orientation.

Claims

1. A slipform paver apparatus, comprising:

a chassis having a direction of operation;

left and right lifting columns configured to adjust the chassis in a heightwise direction;

a drive unit configured to cause the chassis to perform movements in translation and/or rotation;

a control unit configured to actuate the drive unit;

a mold including at least a mold upper part and two opposed mold side parts, the mold side parts being configured to extend down from the mold upper part toward a ground surface to bound a molded structure;

a mounting unit configured to mount the mold including the mold upper part and two opposed mold side parts for molding flowable material such that the mold upper part and two opposed mold side parts are movable with the mounting unit, the mounting unit being pivotably connected to the chassis for pivoting about an axis extending in the direction of operation; and

a pivoter unit connected to the mounting unit and configured to pivot the mounting unit about the axis extending in the direction of operation, so as to tilt the mounting unit independently of any adjustment of the lifting columns;

wherein the control unit is operably associated with the pivoter unit and configured to automatically actuate the pivoter unit to cause the mounting unit and the mold upper part and two opposed mold side parts to perform automatic pivoting movements about the axis relative to the chassis.

2. The apparatus of claim 1, wherein:

the control unit is configured such that the pivoter unit is actuated to cause the pivoting movements of the mounting unit to be performed in a preset movement process.

3. The apparatus of claim 1, wherein:

the pivoter unit includes a drive actuator selected from the group consisting of hydraulic, pneumatic and electric drive actuators.

4. The apparatus of claim 1, wherein:

the mounting unit includes a first fastener configured to cooperate with a complementary second fastener located on the mold.

5. A slipform paver apparatus, comprising:

a chassis having a direction of operation;

left and right lifting columns configured to adjust the chassis in a heightwise direction;

a mold including at least a mold upper part and two opposed mold side parts, each of the mold side parts extending down from the mold upper part toward a ground surface to define a surface of a molded structure;

a mounting unit configured to mount the mold including the mold upper part and two opposed mold side parts for molding flowable material such that the mold upper part and two opposed mold side parts are movable with the mounting unit, the mounting unit being pivotably connected to the chassis for pivoting about an axis extending in the direction of operation;

an actuator connected to the mounting unit and configured to pivot the mounting unit about the axis extending in the direction of operation, so as to tilt the mounting unit and the mold upper part and two opposed mold side parts independently of any adjustment of the lifting columns; and

a control unit operably associated with the actuator and configured to automatically actuate the actuator to cause the mounting unit and the mold upper part and two opposed mold side parts to perform automatic pivoting movements about the axis relative to the chassis.

6. The apparatus of claim 5, wherein:

the control unit is configured such that the actuator is actuated to cause pivoting movements of the mounting unit to be performed in a predetermined sequence.

7. The apparatus of claim 5, wherein:

the actuator is selected from the group consisting of hydraulic, pneumatic and electric drive actuators.

8. The apparatus of claim 5, wherein:

the mounting unit includes a first fastener configured to cooperate with a complementary second fastener located on the mold.

9. A method of molding a structure from a flowable material, comprising:

(a) providing a mold pivotably mounted on a chassis, the mold including at least a mold upper part and opposed mold side parts extending down toward a ground surface, so that the mold upper part and the opposed mold side parts are pivotable about an axis extending parallel to a direction of travel of the chassis, the chassis being supported by left and right lifting columns;

(b) moving the chassis across a ground surface in the direction of travel and continuously molding a continuous structure with the mold, an outer surface of the continuous structure being in part defined by the mold side parts; and

(c) during step (b), pivoting the mold upper part and the opposed mold side parts relative to the chassis about the axis and varying an orientation of the continuous structure relative to the ground surface, independently of an adjustment of the lifting columns.

10. A slipform paver apparatus, comprising:

a chassis having a direction of operation;

left and right lifting columns configured to adjust the chassis in a heightwise direction;

a drive unit configured to cause the chassis to perform movements in translation and/or rotation;

a control unit configured to actuate the drive unit;

a mold including a mold proper bounded by lateral plates extending downward from the mold proper;

a mounting unit configured to mount the mold for molding flowable material such that the entire mold proper is movable with the mounting unit, the mounting unit being pivotably connected to the chassis for pivoting about an axis extending in the direction of operation; and

a pivoter unit connected to the mounting unit and configured to pivot the mounting unit about the axis extending in the direction of operation, so as to tilt the mounting unit independently of an adjustment of the lifting columns;

wherein the control unit is operably associated with the pivoter unit and configured to automatically actuate the pivoter unit to cause the mounting unit and the entire mold proper to perform automatic pivoting movements about the axis relative to the chassis.

11. The apparatus of claim 10, wherein:
