Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a container lifter used during a cargo handling work for delivering a container between a container quay chassis and a container ship.

[Prior art]

Conventionally, as shown in FIG. 9, when carrying out container loading between the chassis 2 of the container quay 1 and the container ship 3,
In order to enhance the cargo handling efficiency, a second trolley 6 is mounted on a support frame 5 horizontally provided at an intermediate height position inside a container crane 4 provided on the lane of the chassis 2.
In this case, it is good to handle the container in the hold of the container ship 3, but when handling the container 7 on the deck or when loading and unloading the container 7 on the deck, It was necessary to lift the container 7 to the upper side with the trolley 8 and then drop it onto the traverse carriage 9 above the support frame 5.

Therefore, there is a problem in that the cargo trolley 8 is lowered to the height of the transverse trolley 9 or transferred from the transverse trolley 9 to the second trolley 6, which results in poor cargo handling efficiency.

Therefore, in order to efficiently carry out cargo handling, the height of the support frame 5 and the second trolley 6 are adjusted by moving the support frame 5 up and down. However, it is also uneconomical because of the dynamic increase in size.

[Purpose of device]

The present invention has been made in order to solve the above-mentioned conventional problems, and it is possible to reduce the size and labor of the lifting device of the delivery platform that delivers the container without impairing the cargo handling function that can efficiently handle the container. The purpose is to provide a container lifter that can be designed.

[Constitution of device]

To achieve the above object, a container lifter of the present invention has an upper platform and a lower platform provided with a plurality of shift carriages in a guide structure supported on a lane of a chassis or supported by a container crane. A container delivery platform that can be positioned at an optimum height is provided, a spreader that can be moved up and down by a rope that passes through the upper platform is provided in the container delivery platform, and the spreader and the container are provided in the guide structure. It is characterized by installing a hoisting device that also functions as both lifting and lowering devices of the delivery platform.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
1 is a side view of a container lifter according to an embodiment of the present invention, FIG. 2 is a front view of FIG. 1, FIG. 3 is a side view of an enlarged main part of a delivery platform of FIG. 1, and FIG. FIG. 5 is a plan view and FIG. 5 is a front view of FIG.

First, as shown in FIGS. 1 and 2, the ship trolley 8 and the container are transferred within the vertical guide structure 10 which is self-supporting on the lane of the chassis 2 for the container or is supported by the container crane 4. We have a delivery platform 11 to do this delivery platform
11 is composed of an upper platform 12, a lower platform 13, a spreader 14 and a shift carriage 15, as shown in FIGS. 3, 4, and 5.

Next, the spreader 14 is suspended by a rope from the hoisting device 17 shown in FIG. 1 provided on the guide structure 10 via the upper platform 12, and also the shift carriage.
Numeral 15 is shiftable on the lower platform 13, and one unit or two units as in the present embodiment is provided.

Further, the upper platform 12 or the lower platform 13 can be vertically positioned and fixed at a plurality of positions of the guide structure 10 by a detachable connecting device 16, but the position of the delivery platform 11 is The hoisting device 17 of the spreader 14 also serves as a feeder.

That is, wind the spreader 14 to the limit,
After the connection guides 18 of the upper platform 12 and 14 are brought into close contact with each other, the connection device 16 with the guide structure 10 is released.

At this time, the upper platform 12 and the lower platform 13 are supported by the spreader 14.

After that, the delivery platform 11 is moved to the optimum position by the hoisting device 17, and is reconnected to the guide structure 10.

Next, the flow of the container 7 by the container lifter 20 will be described. First, in the case of unloading cargo, as shown in FIG. 6, the container 7 from the container ship 3 is placed on the shift carriage 15 from the ship trolley 8 and the shift carriage is 15 is shifted below the spreader 14 of the container lifter 20, where the ship trolley 8 moves to pick up the next container 7.

The spreader 14 of the container lifter 20 picks up the container 7, and the shift carriage 15 shifts to the position for receiving the container from the ship trolley 8 again.

On the other hand, the spreader 14 of the container lifter 20 places the container 7 on the chassis 2 waiting below and returns to the upper limit position again.

Further, in the case of loading and unloading, as shown in FIG. When placed, the shift cart 15 moves to the delivery position to the ship trolley 8, and the spreader 14 of the container lifter 20 again picks up the next container 7.

Then, the ship trolley 8 receives the container 7 from the shift carriage 15 and loads it on the container ship 3.

Next, a case of a dual cycle in which two shift carriages 15 for loading and unloading the container 7 into and from the container ship 3 by one reciprocating motion of the ship trolley 8 are provided will be described. As shown in, the ship trolley 8 places the container 7 picked up from the container ship 3 on the shift carriage 15A.

Shift trolley 15A is spreader 14 for container lifter 20
Moving down, the ship trolley 8 picks up the container 7 on the shift carriage 15B.

Then, the spreader 14 of the container lifter 20 picks up the container 7 on the shift carriage 15A and shifts to the shift carriage 15A.
Moves again to a position for receiving the container 7 from the ship trolley 8.

Next, the spreader 14 of the container lifter 20 puts the container 7 on the chassis 2 waiting at the lower side, receives another container 7 from the chassis 2 waiting next, and winds it up to the upper limit position.

Then, the shift carriage 15B moves below the rolled-up container 7, places the container 7 on the shift carriage 15B, and the shift carriage 15B moves to the delivery position to the ship trolley 8.
