DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above circumstances, and is a wharf capable of carrying a bulking ship on each side, such as unloading work on one side and docking on the other side. It is an object of the present invention to provide a traverse swivel type traveling continuous unloader that can perform work and the like in parallel, and is therefore highly economical.

[0005]

To this end, the present invention provides a traveling continuous unloader installed on a wharf on both sides of which a loading vessel can berth, with a traverse drive mechanism mounted on a traveling gantry capable of traveling along the wharf. A swinging A frame that can be traversed through the swinging A frame, a hoisting boom that pivots the center portion on the swiveling A frame, has vertical loading sections and balance weights on both ends, and is driven up and down, and a boom hoisting angle on the hoisting boom. It is equipped with a fin conveyor that can cope with the increase in the number of the above, and the unloading of one side is performed at the position where the swing A frame is moved to the vicinity of either side on the traveling gantry.
It is characterized in that the end of the undulating boom on the balance weight side operates within a range not exceeding the quay line on the opposite side.

[0006]

According to this structure, the following actions are performed. (1) Since the turning mechanism pivotally supported on the traverse stand that can move to the left and right on the top surface of the traveling gantry, the overhang length on the cargo handling side and the overhang length on the balance weight side of the hoisting boom can be adjusted. Since each can be shortened, the entire structure of the unloader becomes compact, the weight is reduced, the equipment cost is reduced, and the economical efficiency is improved. (2) Since the flat position of the end of the undulating boom on the balance weight side is within the pier, the undulating boom is installed so that one ship on one side of the wharf can freely move to the other side while the other ship is unloading. It is possible to berth at. (3) Since the fin conveyor is provided on the hoisting boom, it is possible to eliminate the loss of the slip of the load from the conveyor due to the increase of the hoisting angle due to the shortening of the hoisting boom length.

It is a screw jack for opening and closing.

In such an apparatus, in order to unload the loading 09 of the loading vessel 01, in FIG. 1, the traverse table 1 is moved to the left full position on the traveling gantry 05, and is operated in the state shown by the solid line. I do. At that time, since the boom length of the hoisting boom 4 is shorter than that of the conventional one, the maximum hoisting angle of the boom at the time of unloading is also larger than that of the conventional one, so that the load on the conveyor boom 5a is easy to slip, 6 prevents the load from slipping and can reliably transfer the load to the chute 011 on the turning A frame 2 without loss. Further, since the relay conveyor 6a is provided, the load 09 of the short 011 can be conveyed to the above-ground conveyor 012. Then, when the loading of the loading vessel 01 is completed, the vertical unloading unit 08 is raised by the hoisting boom 4, turned 180 degrees by the turning A frame 2, and moved to the full right side position by the traverse stand 1 to lift the hoisting boom.

The piston 19 is extended, the square pin 16 is inserted into the square pin hole 20 on the right side by one pitch as shown by the chain line, and the proximal end side pin engaging / disengaging block 14 of the hydraulic cylinder 17 is inserted.
The operation of removing the square pin 16 from the square pin hole 20, shortening the piston 19 and inserting the piston 19 into the square pin hole 20 on the right side by one pitch is repeated. To move to the left, reverse the operation. That is, the hydraulic cylinder 17 and the like are moved by actuating like a worm. In addition, at that time, as shown in FIG. 2, the horizontal platform 1 to which the swivel A frame 2 and the like are attached suppresses the top surface from being lifted by the lift preventing rails 10 and the bottom surface to be a pin hole. Since it is restrained by the attached rail 19a, there is no fear that the turning A frame 2 and the like will fall. In addition,
In the present invention, the configuration of each part of the element is not limited to the above-mentioned embodiment, and any type may be applied and implemented.

According to the apparatus of this embodiment, the following effects can be obtained. (1) Since the turning mechanism pivotally supported on the traverse stand that can move to the left and right on the top surface of the traveling gantry, the overhang length on the cargo handling side and the overhang length on the balance weight side of the hoisting boom can be adjusted. Since each can be shortened, the overall structure of the unloader can be made compact and lightweight, the equipment cost can be reduced, and the economical efficiency can be improved. (2) Since the flat position of the end of the undulating boom on the balance weight side is within the pier, the undulating boom is installed so that one ship on one side of the wharf can freely move to the other side while the other ship is unloading. It is possible to berth at the shore, thus eliminating the waiting time of the bulk carrier and improving its economic efficiency. (3) Since the fin conveyor is installed on the hoisting boom (on the boom conveyor linked with the hoisting boom), the slipping and spilling of the load on the conveyor due to the increase of the hoisting angle of the hoisting boom 4 are prevented, and the A frame is surely provided. It is possible to send cargo to the side.
