[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a horizontal loading and unloading device for horizontal loading and unloading of containers. The present invention relates to a delivery device.

[0002]

[Prior art]

 Generally, a lift-on-lift-off method, that is, a method using a container crane is known as a container cargo handling method between the quay and the ship. However, this loading and unloading method requires not only horizontal movement of the container but also vertical movement of the container, which requires time for the vertical movement of the container. It is not suitable for high-speed cargo handling.

Under such circumstances, it is possible to adopt a horizontal container handling system. As the horizontal loading and unloading method for this container, generally known methods include a roll-on and roll-off method of loading or unloading a container with a container loaded on a chassis and a method of using a forklift.

[0004]

[Problems to be solved by the device]

 The conventional roll-on and roll-off methods have the following problems. That is, in the method of loading containers by loading containers on the chassis, it is necessary to mount a large number of chassis on a ship, and the transport efficiency is reduced because the number of containers to be transported is limited accordingly. Since one container is loaded on the table, the work time cannot be shortened so much.

On the other hand, even in the case of using a forklift, since a heavy container is transferred in a cantilever state, there is a limit to the number of containers that can be transferred, and as a result, the loading / unloading time of the container cannot be shortened as much as expected. There is a problem. For this reason, it is conceivable to load containers on the trolley body of the trolley in multiple stages and in multiple rows, and then load the containers onto the vessel by self-propelling the trolleys and unloading them. Therefore, when there is a difference in height between the quay and the ship deck and the movable ramp has an inclination angle, the driving force of the dolly becomes large, and in some cases, there is a problem that the vehicle cannot travel by itself. .

As a countermeasure for this, a traveling type delivery device having a stage that can be moved up and down is adopted. However, when a trolley with a large carrying weight is self-propelled on a lamp passed from the stage to the boat, the trolley weight is transferred to the boat. Will be received by the tire wheels arranged under the base of the traveling delivery device, and will become unstable due to an unbalanced load generated by the movement of the carriage, and in some cases the delivery device may fall over. There's a problem.

[0007]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned conventional problems. The delivery stage 9 is supported by a lifting device 10 on a base 8 of the delivery device so that the delivery stage 9 can be moved up and down. The supporting member 14 can be fixed, and the wheels 11 are vertically movably supported on the lower part of the base 8 through an upper / lower drive device, and the base 8 is moved up and down by the vertical drive device. In addition, it is a structure of a traveling type delivery device for horizontal cargo handling of a container configured such that the lower part of the base 8 is grounded when descending.

Further, by forming the overhanging portion 8d in the same direction as the method of moving the self-propelled carriage 1 on the base 8, the base 8 is grounded and stabilized, and the overhanging portion 8d causes the delivery device 3 to move. It is possible to prevent the occurrence of the overturning moment of the delivery device 3 when an unbalanced load is applied.

[0009]

[Work]

 The delivery device 3 is self-propelled on the quay 20 to a predetermined position, and at this predetermined position, the elevating device lowers the base 8 to ground it. Thereafter, the self-propelled carriages 1 loaded with the containers 2 in multiple stages and in multiple rows are loaded onto the delivery stage 9 by self-propelling. At this time, if the heights of the delivery stage 9 and the ship deck 6 are different, especially when the ship deck 6 is higher than the delivery stage 9, raise the delivery stage 9 first. The self-propelled carriage 1 is run toward the ship deck 6. As a result, not only the loading time of the container 2 can be shortened, but also when the weight of the self-propelled carriage 1 loaded with the container 2 acts on the delivery device 3, the entire bottom surface of the base 8 of the delivery device 3 is removed. It is grounded on the upper surface of the quay 20 to maintain stability.

[0010]

【Example】

 An embodiment of the container horizontal loading / unloading device according to the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view of a horizontal cargo handling device for containers using the delivery device 3 of the present invention, in which the ramp way 4b at the front of the delivery device 3 in which the movable ramp ways 4a and 4b are extended forward and backward. 5, a self-propelled cart 1 carrying containers 2 in multiple stages and multiple rows travels on the delivery device 3 to transport the containers 2 to a ship 5 and to arrange the containers 2 in parallel on a deck 6. It is designed to be efficiently mounted on the gantry 7.

As shown in FIGS. 2 to 4, the delivery device 3 supports a delivery stage 9 above a base 8 through a hydraulic cylinder 10, and further supports a wheel 11 so that the base 8 can be raised and lowered. I support you. As shown in FIG. 5, a hydraulic cylinder 10 as an elevating device is arranged on the base 8, and a chain wheel 12 is arranged at the upper end of a rod 10a of the hydraulic cylinder 10. A chain 13 having one end attached to the base 8 and the other end attached to the delivery stage 9 is wound around the chain wheel 12.

Therefore, the transfer stage 9 can be moved up and down with respect to the base 8 by operating the hydraulic cylinder 10. Further, the delivery stage 9 is supported above the base 8 via a support member 14, and the support member 14 is configured to be foldable according to the elevation of the delivery stage 9 and at a predetermined position. Is formed so that a stopper (not shown) works.

A movable ramp way 4a on the quay side and a movable ramp way 4b on the ship side are supported on the transfer stage 9 by a ramp support shaft 9a, and are driven so as to be elevated by hydraulic cylinders 15a, 15b. It is designed to form a bridge for ships. As shown in FIGS. 9 and 10, the base 8 has a central portion 8a located at a lower side, and side portions 8b and 8c thereof are bent upward to form lower portions of the side portions 8b and 8c. Rubber tire type wheels 11 are provided respectively.

In the central portion 8a of the base 8, a comb-shaped protrusion 8d is formed in the same direction as the moving direction of the self-propelled carriage 1. The overhanging portion 8d is a member for receiving an unbalanced load generated when the self-propelled carriage 1 loaded with the containers 2 moves on the delivery device 3, and this member prevents the delivery device 3 from generating an overturning moment. It is something you can do.

The wheel 11 is supported via a vertical drive device as shown in FIG. Specifically, the vertical drive device is rotatably supported by a support arm 16, and one end of the support arm 16 is rotatably supported by a support member 17 attached to a lower portion of the base 8, and the like. The end is connected to a hydraulic cylinder 18 attached to the base 8. Therefore, by operating the hydraulic cylinder 18, the base 8 can be raised and lowered within a small range.

A description will be given of a case where the container 2 is loaded on the deck 6 of the ship 5 in the container horizontal cargo handling / delivering device having the above structure. B) The delivery device 3 is moved to a predetermined position in advance, and the hydraulic cylinder 18 constituting the vertical drive device is operated to ground the truck main body 8. (B) Then, as shown in FIG. 7, the self-propelled carriages 1 loaded with the containers 2 in multiple stages and multiple rows are carried in from the movable ramp way 4a onto the delivery stage 9. At this time, the delivery stage 9 is descending.

(C) When the deck 6 of the ship 5 is higher than the delivery stage 9 as shown in FIG. 8, the hydraulic cylinder 18 is operated to raise the delivery stage 9. That is, the delivery stage 9 is raised until the delivery stage 9 is horizontal or slightly inclined toward the ship 5. D) Then, the self-propelled carriage 1 is self-propelled on the deck 6 of the ship 5 via the movable ramp way 4b. After that, the container 2 is lowered by an elevating device (not shown) provided on the self-propelled carriage 1, and is loaded on the container support base 7 as shown in FIG.

It should be noted that in this process, an unbalanced load acts on the delivery device 3 due to the weight of the self-propelled carriage 1 traveling on the movable ramp way 4a, but when the base 8 is inclined, it is provided in front of and behind the central portion 8a thereof. A certain overhanging portion 8d (unbalanced load receiver) comes into contact with the ground, and the falling moment does not act on the delivery device 3, so that the self-propelled carriage 1 can travel in a stable state.

The base 8 needs to be brought into contact with the ground at a predetermined position to be stabilized, but since a driving device for moving the wheels 11 up and down is used for this means, it can be easily grounded. .

[0020]

[Effect of device]

 The traveling type handing device 3 for horizontal cargo handling according to the present invention supports the handing stage 9 so as to be able to move up and down on the base 8 of the handing device via the elevating device 10, and can fix the both by a supporting member 14. At the same time, the wheels 11 are vertically movably supported on the lower part of the base 8 through a vertical drive device, and the base 8 is moved up and down by the vertical drive device. It is configured to be grounded.

Therefore, not only a large number of containers 2 can be handled at once, but also the self-propelled carriage 1 can be easily moved by raising and lowering the delivery stage 9. Further, since the self-propelled carriage 1 is made to travel with the base 8 of the delivery device 3 grounded, there is an effect that the delivery device 3 can have a stable structure.
