Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cargo handling device used for stacking a large number of cargoes such as pallets and containers in multiple rows and in multiple stages.

[Prior art]

Cargoes such as pallets and containers are generally stacked in multiple rows and stacks due to storage space limitations, and forklift trucks are usually used to handle such cargo.

However, when this forklift truck is used, it requires a gap between each row of cargo for the forklift truck to move and handle the cargo, which not only requires more storage space than is necessary, but also requires more storage space than is necessary. Due to requirements such as maneuverability and safety, there will also be restrictions on the stacking of cargo. Therefore, there was a problem in that the storage space could not be used effectively. There was also a problem with operability in that it was impossible to take out a single piece of cargo from a large amount of stacked cargo.

[Purpose of the invention]

The present invention was made in order to solve the conventional problems associated with cargo handling using a forklift vehicle as described above, and its purpose is to: The purpose is to minimize the distance between each cargo row and to stack cargo in as many stages as possible, thereby making effective use of storage space.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention arranges a traveling trolley on a crossbeam of a portal crane, attaches a lifter frame that can move up and down to the traveling trolley, and attaches a guide extending downward to the lifter frame. Install the frame,
The present invention provides a cargo handling device suitable for cargo handling of multi-row and multi-tiered cargo, in which a claw wooden body is arranged that can move up and down along the guide frame and can extend and retract horizontally from the lower end of the guide frame.

The present invention provides a lifter frame that is movable up and down on a trolley that runs on a crossbeam of a portal crane, and this lifter frame has a claw wooden body that can project horizontally or laterally, that is, a flexible claw. It is distinctive in that it is equipped with a device.

The flexible claw wooden body used in the present invention is not always in a protruding state like a fork installed on a forklift vehicle, but is stored in a guide frame provided on the lifter frame when not handling cargo. , which has a protruding structure during cargo handling.

This claw tree body is like a shrimp or a shaft that bends and extends, and in the extended state it becomes rigid and can lift heavy cargo.

In a preferred embodiment of the claw wood body, claw units having a trapezoidal cross section are prepared, arranged so that the inclined surfaces of the claw units are in contact with each other, and connected by providing a hinge at the upper part.

Since the present invention is configured as described above, as long as there is a space in which the gate type crane can move, cargo can be closely spaced and loaded in multiple stages, and the cargo handling space can be used effectively. Can be done.

〔Example〕

Hereinafter, based on FIGS. 1 to 4, the multi-row according to the present invention,
An embodiment of a cargo handling device suitable for handling multi-level cargo will be described.

Fig. 1 shows the state in which cargo W loaded on a truck T is unloaded into a storage area, in which the trunk T can pass inside the portal crane 1, and multi-level cargo W can be arranged in double rows. It is structured as follows. A traveling trolley 2 is arranged on the upper crossbeam of the recessed crane 1, and a lifter frame 4 to which four guide frames 3 are attached so as to extend downward is attached to the traveling trolley 2 so as to be movable up and down. ing. As will be described later, a claw wooden body 5 is attached to the guide frame 3, which can extend and retract from its lower end in the horizontal direction.

To be more specific, the guide frame 3 has a box shape as shown in FIGS. 2 and 3, is erected at the four corners of the lifter frame 4, and has a direction changing section 6 formed at its lower end. An opening 7 is provided inside. A screw jack 8 rotated by a drive device (not shown) and a traveling nut 9 that moves up and down as the screw jack 8 rotates are disposed inside the nut.

As shown in FIG. 2, the claw wood body 5 has a trapezoidal first claw unit 10 having an inclination angle θ downward from the top, and a trapezoidal second claw unit unit 10 having an opposite inclination angle θ'. The claw unit bodies 11 are arranged alternately, the brackets 12 are made to protrude from the upper part, and the brackets 12 are connected with each other by pins 13 to form a hinge.

That is, the claw wood body 5 is configured to be bendable on the hinge side. The base portion 5a of the claw wooden body 5 is attached to the base portion of the traveling nut 9 by a pin 14, and is provided with a fitting portion 16 into which a lock pin 15, which will be described later, is fitted. Note that a contact plate 14 is provided on the inclined surface (side surface) of the claw unit 10.11 to increase withstand pressure.

As shown in FIG. 3, a support stand 17 is provided at the lower end of the guide frame 3, and a hydraulic piston 18 for actuating the lock pin 15 is provided on the support stand 17.

A support plate 19 is provided on the upper surface of the claw wooden body 5 to prevent the cargo W from coming into direct contact with the bracket 12 and pin 13 forming the hinge.

In the cargo handling device for multi-row, multi-tiered cargo, a case will now be explained in which the cargo W stacked in multiple stages is lifted.
First, the gantry crane 1 and traveling trolley 2 are operated to position the lifter frame 3 on the target cargo W. Thereafter, when the lifter frame 3 is lowered and the lower end of the guide frame 3 reaches a position slightly below the target cargo W, the screw jack 8 is rotated by a drive device (not shown).
Lower the traveling nut 9. At this time, the claw unit body 10 at the tip of the claw wood body 5 contacts the inner surface of the direction changing part 6, bends inward about the pin 14, that is, in the horizontal direction, protrudes from the opening 7, and It is inserted into the space between the cargo W provided in the vertical direction.

When the tracking nut 9 reaches the lower end of the guide frame 3 and the claw wooden body 6 is completely inserted into the lower part of the cargo W, the hydraulic piston 18 is actuated, the lock pin 15 is inserted into the fitting part 16, and the claw is inserted into the fitting part 16. The wooden body 6 is fixed and maintained in a laterally protruding state. Then, when the lifter frame 4 is raised, the cargo W is lifted. In addition, when loading cargo W, this operation may be performed in reverse.

In FIG. 3, a guide frame 3 is installed at the four corners of the lifter frame 4, and the claw wooden body 5 is
is configured to protrude inward. In this drawing, a pallet is depicted as the cargo W, and a box body 20 is formed of corrugated board at the bottom of the pallet, and the structure is such that a claw wooden body 5 can be inserted into the inside of this box body 20. ing.

Of course, the present invention is not limited to the above embodiments,
A hydraulic piston may be used to move the claw wooden body 6 up and down (various changes can be made without departing from the gist of the invention).

〔Effect of the invention〕

As is clear from the above description, according to the cargo handling device according to the present invention, not only can multiple stacks of cargo W be stacked upward more quickly because it uses a recessed crane, but also the cargo handling device according to the present invention can not only carry out multi-level stacking upward more quickly, but also have a hook for lifting the cargo W. The body 5 is not stored in the guide frame 3, which is set up in the vertical direction, but is made to protrude horizontally when in use, so that the distance between each row of cargo W can be kept to a minimum. This has the effect of making it possible to effectively utilize storage space.
