Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a positioning device suitable for a hanger, particularly a container hanger.

[Conventional technology]

As shown in Japanese Utility Model Application Publication No. 54-49374, a container hoist is used to lift a container by engaging twist lock pins of the hoist with four hanging points on the top surface of the container. In order to prevent the four twist lock bins from engaging with the four hanging points, a hanging tool positioning device is provided at four points of the hanging tool.

When alignment is required, the positioning device causes the flipper located directly above the hanging tool to project downward from the side of the hanging tool.
The container is accessible. When alignment is required, the flipper is raised and positioned directly above the hanging tool.

As shown in FIG. 1 of the above-mentioned publication, a rotating cylinder is used to move the flipper about 170 mm.
There is a rotating cylinder device that rotates the cylinder. Furthermore, as shown in FIGS. 2 and subsequent figures, there is a link system using parallelogram links and cylindrical links.

[Problem that the invention seeks to solve]

The rotating cylinder method described above uses a rotating cylinder and is therefore expensive.

The above-mentioned link method is relatively inexpensive, but since the flipper moves up and down almost vertically, the amount of lateral protrusion from the hanger is small.

There are three ways to use the flipper for alignment:

The first method is to raise and lower the hanger with the flipper protruding to the lowest position.

The second method is to protrude the flipper halfway, stop the flipper operation, then lower the lifting tool, and when the flipper hits the container, resume the lowering of the flipper and shorten the distance between the pair of flippers. This method involves moving the hanging device laterally and positioning it directly above the container.

The third method is to lower only the two flippers located upstream in the traveling direction of the trolley suspending the hanging equipment, and cause the trolley to collide with the two lowered flipper containers as the trolley travels. Next, the other two flippers are lowered to align the hanging tools.

However, the second method and the third method are difficult to perform with the devices of the two methods described above.

That is, in the rotary cylinder method, since the flipper rotates around the rotary cylinder, the flipper can thicken (protrude) laterally. Therefore, alignment is performed using the second method and the third method. You can, but
Since the output of the rotating cylinder is small, this method cannot be practically adopted. The more you try to increase the output of the rotating shilling, the more expensive it becomes.

Further, since the lateral protrusion is small in the link method, this second method cannot be practically adopted.

Furthermore, in the third method, it is sufficient if the two flippers lowered in advance hit the container at the same time.
Since the hanging device (trolley) is often positioned diagonally with respect to the container, one of the two flippers that is lowered often hits the container first. In this case 1. When the hanging tool skews, alignment cannot be performed until the skew stops, reducing cargo handling efficiency.

An object of the present invention is to provide an apparatus that is easy to align and is inexpensive.

[Means for solving problems]

The above object is to provide pinions having rotation centers in a direction parallel to each moon in the vicinity of two orthogonal corners of the main body of the hanging device, to attach a flipper to each pinion, and to This is achieved by providing a member having two racks that engage with each pinion so as to be movable up and down by a cylinder device installed in the main body. .

[For production]

When the cylinder device is actuated, the flipper rotates. Since a cylinder device can be used, the configuration can be made inexpensive.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Positioning devices are installed on the upper surface of each of the four corners of the main body l of the hanging tool. A twist lock pin (not shown) is provided at the bottom of the main body l, and guide rollers 3 are provided on the top surface for inserting the hoist into the ship.

Two flippers 11 are provided at each corner, and the flippers 11 are provided in orthogonal directions. Each flipper 11
is attached to a part of the pinion crest by bolts or welding, and this pinion hill is driven by a rack 13 to rotate the flipper 11. The rotating shaft of each pinion hill is not supported by a bladder 15 on the upper surface of the main body 1.

The rotation axis of each Binion hill is provided parallel to the side surface of the main body 1. Therefore, the rotations are orthogonal to each other. It is necessary for the rack 13 to drive two Binion hills at the same time, and as shown in the figure, the rack is constructed so as to be installed on two mutually orthogonal surfaces (i.e., on the outer surface of each moon of the L-shaped member). The rack 13 is provided vertically.

The end of the rack is connected to a hydraulic cylinder device (
9) is connected to the end of the rod. This causes the rack 13 to move vertically. A bracket 17 connects the rod and the rack 13.

The four points on the top, bottom, left and right of the back side of the rack 13 are guide rollers ρ.
is in contact with. The guide roller n is attached to a bracket B installed upright on the upper surface of the main body 1. Furthermore, two guide roller laths are provided that are in contact with the corners between the two rack surfaces of the rack 13. 5 is a bracket for that purpose. Note that the guide roller row and bracket B are not shown in FIGS. 1 and 2.

In this configuration, when the hydraulic cylinder device is operated to cause the rod to protrude, the rack 13 is raised and the flipper 11 is lowered as shown. Conversely, if you move the rod back,
The rack 13 descends, the flipper 11 rotates and rises,
It fits inside the main body 1.

Since a hydraulic cylinder device is used as a cantering source for the flipper 11, the driving force can be sufficiently increased, and the second method and the third method can be employed. Moreover, it can be made at low cost.

In addition, as shown in FIG. 4 (when the hanger is viewed from above, the distance from one end of the flipper to the other end of the flipper at the - corner is longer than that of the conventional case (11a - 11b)). This is larger than in the case of one flipper 11c (11A-ue).Therefore, when alignment is performed using the third method, early cage alignment can be performed.

That is, the above! When positioning is performed using the method of 43, it is rare for the flippers at the two left and right corners to collide with the container joint at the same time, and as shown in FIG. are often the first to collide. In this case, since the suspension swings due to the reaction force of the collision, alignment cannot be performed until the swing becomes small. However, in the present invention, since the distance between the ends of the pair of flippers is large, the end 11 of the flipper at the other corner (left side)
Since the container joint is located near d, that is, the container joint is likely to be located within the range of the four flippers,
This allows the shaking to subside quickly and alignment to occur quickly.

And since each side of the L-shaped member is provided with a rack,
- The two flippers at the corners can be driven by one device, making it inexpensive. The distance between the two flippers is determined by the distance from the corner of the L-shaped member to the center of the surface of the rack.

〔Effect of the invention〕

According to the present invention, two flippers can be driven by one device, the structure can be simplified, and a strong flipper can be obtained.
