Description

[Detailed description of the invention] The present invention relates to a cargo handling device for heavy and long cylindrical bodies such as pipes, and is capable of safely and conveniently handling cylindrical bodies in narrow spaces such as ships and within the range of movement of cranes and other cargo handling equipment. The purpose is to provide a device that can be easily used.

In conventional cargo handling of the cylindrical body 1, for example, when loading it into a ship, there is a deck 21 above the hold 20 as shown in FIGS. 7 to 10, so cargo handling to both sides 22 of the hold 20 is difficult. , as shown in Figure 10, transverse cargo handling was being carried out by input.

Similarly, in warehouses and the like, cargo handling in places where the range of movement of cranes and the like is limited has been carried out manually by horizontal transport.

That is, as a conventional method for loading and unloading cargo into the side 22 of the hold 20, as shown in FIG.
are placed on the dunnage 24 as shown in FIG. 8, the wire rope 23 is loosened, and both ends of the cylindrical body 1 placed in parallel on the dunnage 24 are fixed with pawls 25 so as not to roll. Remove the wire rope 23.

Next, when trying to send out the cylindrical body 1 horizontally, first, as shown in FIG.
After installing a pawl 25a on the cylindrical body 1b adjacent to the cylindrical body 1b to prevent transfer, the pawl 25 at the outer end is removed, and the cylindrical body 1a is manually rolled onto the side 22 of the hold 20, as shown in FIG. This series of operations is carried out at 1 of cylindrical body 1.
The cross-transfer cargo handling is completed piece by piece.

The conventional loading and unloading of the cylindrical body 1 on board a ship as described above is time-consuming and extremely tiring for the workers, and during the rolling work of the cylindrical body 1, which is a heavy load, the rolling cylindrical body 1 may be accidentally touched. This is an extremely dangerous operation that can lead to personal injury, and there has been a desire for a cargo handling device that does not have these drawbacks and can be operated safely and easily.

The present invention meets the above-mentioned demands, and its configuration will be explained below with reference to the drawings.

In the embodiment shown in FIG. 1, there is a short pedestal 3 above the pedestal 2, which is supported at its center by a support 4 projecting from the pedestal 2 and a horizontal support shaft 5. The pedestal 3 is rotatably supported at a distance from the pedestal 2.
A short guide plate 6 is pivotally attached to each end of the pedestal 3 via a hinge 7 so as to be rotatable in a direction perpendicular to the longitudinal direction of the pedestal 3.

The length of the guide plate 6 is such that the pedestal 3 is inclined to one side,
At the position where the descending end (the right end in the illustrated example) comes into contact with the receiving pedestal 2, the rising end (in the illustrated example, the left end) becomes a supporting plate for the receiving pedestal 2, and has a length that hangs below the rising end. The tip of the hanging guide plate 6 is brought into contact with the cradle 2 and locks the pedestal 3 in its inclined position so as not to rotate.

In addition, it is preferable that the tip of the guide plate 6 is made gradually thinner so as not to hinder the transfer of the cylindrical body, which will be described later.

On the upper surface of the receiving pedestal 2, a rotating shaft 8 is rotatably supported and extended in a bearing 9 over substantially the entire length below the pedestal 3 in the longitudinal direction. , each 2
The claws 10 of the wooden pair are at a predetermined angle (for example, about 120 degrees) in the circumferential direction, and both sets are in the same phase position,
The two claws 10, which are installed perpendicularly to the axis of the rotating shaft 8, and which are closer to the same end, are attached to the cylindrical body 1 to be placed, respectively.
They are planted at a pitch approximately equal to the diameter of.

In the illustrated example, among the claws 10 on the near side, the left claw 10a and the right claw 10b are planted parallel to each other, and the claw 1 on the opposite side
0, the left claw 10c and the right claw 10d are planted parallel to each other, and the claw 10a.

The set of claws 10b and the sets of claws 10c and 10d are planted at an angle of approximately 120 degrees, and the claws 10a and 10c1 and the claws 10b and 10d are planted at a pitch approximately equal to the diameter of the cylindrical body 1. It is set up.

In the illustrated example, the claws 10a and 10b are both closer to the ends, but the claws 10a and 10b or the claws 10b and 10c may be closer to the ends.

Furthermore, notches 11 are provided on both side edges of the pedestal 3 at positions where the four pawls 10 are rotatably inserted when the pivot shaft 8 rotates to project them onto the upper surface of the pedestal 3. 2 each on the left and right
Notched individually.

Note that the upper end of the support column 4 is set to a height that does not protrude from the upper surface of the rotating and tilting pedestal 3.

Next, the functions and effects of the present invention will be described.

First, as shown in FIG. 7, in the cargo handling range of a crane or the like at the bottom of the hold 20 or on the dunnage 24 where the cylindrical bodies 1 are to be loaded onto the ship, a receiving frame 2 is placed in a second position in a direction perpendicular to the cylindrical bodies 1 to be arranged. As shown in the figure, two pieces are placed in parallel.

Next, as shown in FIG. 1, the pedestal 3 is tilted toward the side 22 side (right side in the illustrated example) of the cargo hold 20 where cargo is to be handled, and the guide plate 6 on the opposite side (left side in the illustrated example) is made to hang upright, and its lower end is brought into contact with the upper surface of the pedestal 2 to maintain the inclined posture of the pedestal 3.

Next, as shown in FIG. 2, the rotating shaft 8 is rotated so that the claw 10b on the lower end side of the inclination is in a nearly upright position and protrudes above the upper surface of the pedestal 3 within the notch 11.

At this time, the claw 10a at the other end on the same side also takes a nearly upright position, and the claws 10c and 10d on the other side are hidden below the upper surface of the pedestal 3.

When the cylindrical body 1 is placed suspended on the cargo handling equipment in this position using a crane or the like and the wire rope is removed, the cylindrical body 1 rolls in the direction of inclination of the pedestal 3 and hits the claw 10b, as shown in FIG. It is stopped at the position of contact.

Next, insert the pipe 12 into the claw 10a at the other end that stands upright, and simultaneously rotate the rotation shaft 8 in the direction of arrow A as shown in FIG. , 10b gradually descend, and the tips of the waist claws 10c, 10d gradually rise.

If the angle between the pawls 10a, 10b and the pawls 10c, 10d is appropriately selected (this angle is about 120 degrees), the pawl 10b will drop from the top surface of the pedestal 3, and at the same time it will lose its pawl action. 10d protrudes above the upper surface of the pedestal 3, and the right end cylindrical body 1c is made freely removable, and at the same time, as shown in FIG. 4, the second cylindrical body 1d is stopped by a pawl 10d.

The cylindrical body 1c rolls to the right on the inclined pedestal 3 and the right guide plate 6, and rolls into the right side end of the hold.

Next, as shown in FIG. 5, when the vibrator 12 is rotated in the direction of arrow B, the rotation shaft 8 rotates in the opposite direction to the above, the tip of the claw 10d descends, and the tip of the claw 10b rises. The pawl of the cylindrical body 1d by the pawl 10d is released, and at the same time the pawl 10b is released from the pedestal 3.
In order to protrude above the surface, as shown in FIG. 6, all the cylindrical bodies 1, including the cylindrical body 1d, move along the inclined surface of the pedestal 3 and move to the right until the cylindrical body 1d is stopped by the pawl 10b.

Thereafter, by repeating the above-mentioned working steps, the rotation shaft 8 is repeatedly rotated left and right, and the cylindrical body 1 is safely traversed to the side of the ship's hold for loading and unloading.

When loading and unloading cargo to the left side, by reversing the inclination of the pedestal 3, it is possible to carry out traverse loading and unloading to the cargo hold side using the same working process as described above.

Since the present invention has the configuration described in the claims of the utility model registration, it can be used for cargo handling of cylindrical objects such as pipes and columns, even in narrow spaces such as the side of a ship's hold, and even outside the range of movement of a crane or the like. This is an excellent device that allows for safe and easy cross-feeding work, has a simple structure, and is easy to move.
