At present, the known loading and unloading machinery for loading and unloading large items on a ship can only move items one way at a time. For example, the most advanced machinery for loading and unloading containers is now used in large container terminals in the world. Its structure is as follows: There is a shore rail parallel to the shore, and a bracket with wheels is provided on the shore rail. The entire bracket can be moved along the shore rail. The upper part of the bracket is provided with a cantilever from the shore to the sky above the ship. A crane is set on the cantilever. The crane is towed by steel ropes or can use its own power to move back and forth along the cantilever. The crane is equipped with a complete set of lifting equipment such as electric hoisting, lifting machinery and spreaders. The crane is equipped with a console. Control cables and power supply cables, this kind of machinery is referred to as conventional shore bridge. When the conventional shore bridge is used to unload the cargo from the ship, the operator controls the crane to move above the cargo on the hold and lowers the spreader to lift the cargo, and then controls the crane to go to the shore. After dropping the cargo, the empty vehicle returns to the ship for the next Hoisting cargo is the opposite when loading cargo on a ship. Such loading and unloading machinery has no load and low efficiency during the return trip.

Therefore, providing an efficient ship unloader has become an urgent problem in the industry.

The overhead crane 4 is marked with a prominent mark, and the selection control button of the wireless remote control is marked with a corresponding mark. Such as the use of eye-catching colors or eye-catching numbers to distinguish different cranes 4.

Please refer to FIG. 5. In order to facilitate the overhead traveling of the overhead traveling vehicle 4 between the upper guide rail and the lower guide rail 30, the cross-sectional structure of the bracket 2 can be designed into an H shape or an inverted U shape.

Please refer to FIG. 1 to FIG. 6 together, and take an operation process of one of the cranes 4 as an example to introduce the use process of the present invention. When the cargo ship 7 docks at the dock 8, the cantilever 3 approaches the cargo The section of the ship 7 is rotated from the normal state perpendicular to the ground to the horizontal state. When the operator presses the selection control button with the same striking indication as the crane 4, the operator selects the crane 4 for operation, and then presses Press the down left or right button to make the overhead crane 4 run to the cargo to be lifted, then press the down button to lower the spreader 45 above the cargo. After positioning and docking, press the lift button to raise the spreader 45 with the cargo. To a certain height, then press the left or right button to move the overhead crane 4 to the dock 8 and press the lower button to place the cargo on the dock. After the spreader 45 and the cargo are undocked, the spreader is stowed and continues to press the left or right button to lift crane running guide rail 4 to 91, press the button to increase the elevating guide rail ⁹¹ carries a crown block 4 from the lower guide rail 30 moves together with the upper guide rail 30, then press the left or The right button moves the overhead crane 4 along the upper rail 30 to the lift rail 91 at the other end of the cantilever 3. Pressing the lower button causes the elevator rail 91 to carry the overhead crane 4 from the upper rail 30 to the lower rail 30 together, press again left 4 ugly right by the crane 4 to run over the next cargo lifting needs into the next movement cycle.

Similarly, if the container continuous ship unloader of the present invention is used in the reverse direction, the cargo on the dock 8 can be transported to the cargo ship 7.

In the same way, multiple operators can use a wireless remote control to remotely control multiple overhead cranes 4. For example, when unloading is needed, the operator No. 1 carrying the wireless remote control instructs the crane 4 on the dock 8 to fully close the spreader 45 and unload the crane 4 one by one through the upper rail of the cantilever 3. 30 is sent to the direction of cargo ship 7, and the operator 2 carrying the wireless remote control instructs the empty crane 4 to descend to the lower rail 30 of the cantilever 3 and instructs the crane 4 to lower the spreader 45 to lift the cargo from the cargo ship 7, and then The crane 4 that has hoisted the goods is sent to the dock 8 via the lower rail 30 of the cantilever 3, and the operator 3 instructs the sky After W truck 4 unloads the cargo on dock 8, the crane 4 is sent to the head 5 of the cantilever 3 for the operator No. 1; when loading to the cargo ship 7, the operator No. 3 instructs the dock 8 to be located on The crane 4 on the lower rail 30 of the cantilever 3 is loaded and sent to the cargo ship 7 via the lower rail 30 of the cantilever 3, and the operator 2 instructs the crane 4 to unload the cargo on the cargo ship 7. The operator 1 instructs After unloading, the crane 4 fully gathers the spreader 45 and returns to the shore via the upper guide rail 30 of the cantilever 3 for use by the operator No. 3. Operators can also assign their operational tasks in other ways they see fit.

As a preferred mode of the present invention, the overhead crane 4 runs on the upper guide rail 30 of the cantilever 3 when the crane 45 is fully loaded and fully retracted, and the overhead crane 4 runs on the lower guide rail 30 of the cantilever 3 when it is loaded.

In addition, the container continuous ship unloader of the present invention can be equipped with a computer safety monitoring system and a coordinated operation control system for safety supervision and coordinated scheduling of the loading and unloading process. Example 2

As another embodiment of the present invention, it is not necessary to layer the guide rails 30 on the basis of the first embodiment. As long as the guide rails 30 are looped into a loop on the same horizontal plane, the purpose of circulating operation can be achieved, which can save two End lifting device 9, reducing costs. Example 3

As another embodiment of the present invention, the guide rail 30 may be composed of a guide rail group consisting of one steel beam, three steel beams, or three or more steel beams 31, as long as the corresponding structure of the overhead crane 4 changes correspondingly according to the shape of the guide rail 4. .
