Description

Technical Field

[0001] The invention relates to a gust and typhoon protection technology for large-scale machinery at a container terminal, and in particular to a wind protection device technology for large-scale machinery at a container terminal. Background Art

[0002] Large-scale machinery at container terminals, in gusty or typhoon environments, is braked and prevented from slipping by brakes, wheel clamps, rail clamps, iron wedges, large and small car anchors and other anti-skid devices equipped on the large-scale machinery itself, and inertial braking devices equipped on the walking mechanism, to prevent the large-scale machinery from moving in the direction of the large car. In order to prevent the large-scale machinery from moving horizontally and overturning under the action of gusts or typhoons, it is necessary to anchor the main body of the large-scale machinery to the ground through windproof cables or windproof rods. At present, even for large-scale container loading and unloading machinery configured in fully automated terminals, whether it is windproof rods or windproof cables, their operation still adopts manual anchoring by manually adjusting the hooks one by one. Not only does it take a long time to adjust one by one, it is time-consuming and labor-intensive, but it cannot be automated, which is extremely incompatible with the control requirements of fully automated terminals.

[0003] By changing the traditional manual operation mode and eliminating the need for manual intervention in adjusting the attachments one by one on site, the automated control of windproof rods and large-scale machinery can be achieved efficiently and accurately, thereby automatically completing the anchoring of windproof cables or windproof rods.

That is, the anchoring of the windproof pull rod is automatically completed.

[0045] When the anchoring of the large-scale machinery at the container terminal is released, the locking shaft telescopic motor 1000 is started, and the motor shaft 1009 drives the nut 1010 in the shaft hole to rotate, driving the telescopic screw shaft 1002 to move downward, and the lock of the locking shaft 700 drops vertically through the buffer coupling 500, and the locking hook anchor surface 705 is separated from the ground anchor seat lock body.

The lock shaft telescopic motor 1000 continues to work, driving the telescopic screw shaft 1002 to move downward, so that the guide pin 602 in the slide seat 600 on the lock shaft slides from c to d, and then to e, the lock of the lock shaft 700 rotates 90 degrees, the lock hook anchor surface 705 of the lock shaft 700 rotates out of the vertical projection area of ​​the anchor seat hook surface, and the lock shaft telescopic motor 1000 is turned off; then the lock shaft telescopic motor 1000 rotates in the opposite direction, so that the anchor lock shaft 700 retracts and rises to the initial position, and the lock shaft telescopic motor 1000 stops.
