Device for controlling a container, particularly a bottom-unloading container
View Patent ↗Controlling a container, such as a spreader, is described for engaging, retaining, and moving containers, as well as for unloading containers, particularly bottom-unloading containers. A spreader includes a frame having mounted thereon twistlocks, an actuator, a movable engagement mechanism, and force transmission means connecting the actuator and the movable engagement mechanism. The actuator and the force transmission means are substantially disposed along the long sides of the frame, and the movable engagement mechanism is substantially disposed on the short sides of the frame. The actuator allows the movable engagement mechanism to move reciprocally primarily in a direction perpendicular to the plane of the frame. The spreader significantly expands the functionality of devices used for engaging, retaining, moving, and unloading containers, makes it possible to unload a bottom-unloading container, and also allows the automation, simplification, and acceleration of the unloading process of such a container.
1. A device for controlling a bottom dump-container and controlling batches thereof, comprising:
a frame having mounted thereon twistlocks, an actuator, a movable engagement mechanism having engagement means, and a force transmission means connecting the actuator and the movable engagement mechanism,
the actuator and the force transmission means being substantially disposed along long sides of the frame,
the movable engagement mechanism being substantially disposed on short sides of the frame, and
the actuator being configured to allow the movable engagement mechanism to move reciprocally primarily in a direction perpendicular to a plane of the frame so as to engage the engagement means with respective means of the hatches and control the hatches.
2. The device for controlling the container according to claim 1 , wherein the actuator is substantially disposed in a middle part of the frame.
3. The device for controlling the container according to claim 2 , wherein the actuator is a hydraulic drive comprising at least one hydraulic cylinder.
4. The device for controlling the container according to claim 1 , wherein the actuator is a hydraulic drive comprising at least one hydraulic cylinder.
5. The device for controlling the container according to claim 4 , further comprising a pressure generating device for the hydraulic drive.
6. The device for controlling the container according to claim 4 , further comprising a pressure supply means for the hydraulic drive.
7. The device for controlling the container according to claim 1 , wherein the force transmission means are a cable-block mechanism.
8. The device for controlling the container according to claim 7 , wherein the cable-block mechanism comprises a pulley block.
9. The device for controlling the container according to claim 1 , wherein the movable engagement mechanism comprises a rotary mechanism and an additional twistlock engaging a mating part of the container.
10. The device for controlling the container according to claim 9 , wherein the actuator and the force transfer means are configured to allow the additional twistlock to move rotatably.
11. A method for controlling a bottom-dump container and controlling hatches thereof, comprising:
providing a device having a frame having twistlocks mounted thereon, an actuator, a movable engagement mechanism having engagement means, and a force transmission means connecting the actuator and the movable engagement mechanism, the actuator and the force transmission means being substantially disposed along long sides of the frame, the movable engagement mechanism being substantially disposed on short sides of the frame; and
directing the actuator to allow the movable engagement mechanism to move reciprocally primarily in the direction perpendicular to a plane of the frame so as to engage the engagement means with respective means of the hatches and control the hatches.
12. The method for controlling the container according to claim 11 , wherein the actuator is substantially disposed in a middle part of the frame.
13. The method for controlling the container according to claim 12 , wherein the actuator is a hydraulic drive comprising at least one hydraulic cylinder.
14. The method for controlling the container according to claim 11 , wherein the actuator is a hydraulic drive comprising at least one hydraulic cylinder.
15. The method for controlling the container according to claim 14 , wherein the device further comprises a pressure generating device for the hydraulic drive.
16. The method for controlling the container according to claim 14 , wherein the device further comprises a pressure supply means for the hydraulic drive.
17. The method for controlling the container according to claim 11 , wherein the force transmission means are a cable-block mechanism.
18. The method for controlling the container according to claim 17 , wherein the cable-block mechanism comprises a pulley block.
19. The method for controlling the container according to claim 11 , wherein the movable engagement mechanism comprises a rotary mechanism and an additional twistlock engaging a mating part of the container.
20. The method for controlling the container according to claim 19 , wherein the actuator and the force transfer means are configured to allow the additional twistlock to move rotatably.
