DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cargo handling device,
For example, the present invention relates to a cargo handling device suitable for a ship or plant having a vertical and narrow carry-in / out port and a carry-in / out route.

[0002]

2. Description of the Related Art Conventionally, loading and unloading work in a place having a vertical loading / unloading entrance and a loading / unloading route is mainly performed by temporarily installing a hoist, and lifting and lowering the load by the hoist.

[0003]

However, when a hoist is temporarily installed in a place having a vertical loading / unloading port and a loading / unloading path to lift / hang a load, if the loading / unloading port and the path are narrow, The luggage may wander due to the sway of the hull, the wind, or the like, and the luggage may come into contact with the structure around the carry-in / out entrance and the carry-in / out route, which is problematic in terms of safety and luggage protection. Further, installation and transport of the hoist require time and labor, and there is a problem in labor saving and speeding up of the operation. The present invention seeks to solve such a problem.

[0004]

According to the present invention, there is provided a cargo handling apparatus, comprising: a support frame; a winding drum rotatably mounted on the support frame and rotated by a motor; and a hoist mounted on the support frame. , A transport cage suspended on the hoist, a pair of left and right guide wires wound on the winding drum, and weights attached to the lower ends of the guide wires and settable on the floor. A predetermined tension is given to each of the guide wires by adjusting the torque of the motor, and the guide wires form a guide track for elevating and lowering the transport cage, which is a means for solving the problem.

[0005] Further, in the present invention, in the above-mentioned cargo handling device, a wheel and a stopper are attached to the support base as a means for solving the problem.

In the cargo handling apparatus of the present invention, a weight connected to a pair of left and right guide wires is installed on a floor surface by using a winding drum rotatably mounted on a support base, and a predetermined tension is applied to the guide wires. The carrying wire is carried up and down by using the guide wire as an elevating guide track of the carrying cage to carry in / out the cargo. The lifting of the transport cage is operated by a hoist fixed to the support base,
The lifting of the weight and the adjustment of the tension of the guide wire are performed by adjusting the torque of the drive motor of the winding drum. Also, since the support base can be moved by wheels and can be fixed at a predetermined position by tosper,
It can be used by moving to various loading / unloading ports.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic perspective view of a cargo handling apparatus according to an embodiment of the present invention.

In this embodiment, a ship such as a submersible, in which narrow entrances and exits are provided in a plurality of stages in the vertical direction and which communicates with each entrance and exit to form a vertical and narrow entrance / exit route. Reference numeral 101 denotes a deck, reference numeral 102 denotes a middle deck, and reference numeral 103 denotes a floor surface. A loading / unloading entrance 104 is formed in the deck 101,
The loading / unloading port 10 is located vertically below the loading / unloading port 104 on the central deck 102.
5 are formed. A support base 9 is provided so as to surround the loading / unloading port 104 on the deck 101.

The support pedestal 9 includes a main body 90 formed of four pillars and having a substantially square shape in a plan view, four leg members 91 suspended at four corners of the main body 90, and a main body 90. Each of the leg members 91 has a lower end and a stopper 10 and a wheel 11 attached thereto. Therefore, the support base 9 can be easily moved to an arbitrary place on the deck 101, and can be fixed to the place (by operating the stopper 10).
The motor 3 is attached to one of the columns 92. Further, the winding drum 2 whose base end (the left end in FIG. 1) is connected to the rotating shaft of the motor 3 has its front end (the right end in FIG. 1) rotatably supported by the other support 92. I have.

A pair of left and right guide wires 1 are wound around the winding drum 2.
A weight (weight) 5 is attached to the lower end of the body. Therefore, the weight 5 can be raised and lowered by rotating the winding drum 2 using the motor 3 as a drive source. Then, the weight 5 is placed on the floor 103,
In addition, by finely adjusting the torque of the motor 3, the two guide wires 1 can be given a predetermined tension.

In this way, the two guide wires 1 to which a predetermined tension has been applied constitute the elevating guide trajectory of the transport cage 6. Reference numeral 6 denotes a transport cage capable of accommodating transported luggage.
A pair of guide rollers 7 that are in contact with the guide wire 1 are attached. Further, a hoist 4 for raising and lowering the transport cage 6 is attached to the support base 9.
Reference numeral 93 indicates a mounting member for supporting the hoist 4. Reference numeral 8 indicates a pulley with a hook suspended from the wire 41 of the hoist 4.

At the upper four corners of the transport cage 6, hanging wires detachable from the hooked pulley 8 of the hoist 4.
61 are attached respectively. In the above-described configuration, the hoist 4 can be operated to vertically move the transport cage 6 along the two guide wires 1.
The two guide wires 1 serving as orbits are provided with tension, and when the transport cage 6 moves up and down, the guide rollers 7 roll along the two right and left guide wires 1 which are provided with tension and are in tension. Therefore, it is possible to prevent the transport cage 6 from swaying when the transport cage 6 is moved up and down, and it is possible to safely carry in and out the load in a narrow space.

The lifting speed of the transport cage 6 is adjusted by operating the hoist 4. Also, two guide wires 1
Is to finely adjust the torque of the motor 3 so that the weight 5 does not wobble or slide, and the two guide wires 1 have a tension that can prevent the transfer cage 6 from rolling. The adjustment of the tension is performed. The support base 9 has a main body 90, a leg member 91 and a support 92.
Are made of a columnar member, so that they are formed in a lightweight but highly rigid structure, and wheels (casters) 11 are attached to the lower end of each leg member 91, so that they can be easily moved. Can be done. A stopper 10 attached to the lower end of each leg member 91 is also provided.
As a result, the support base 9 can be fixed at a predetermined position, so that the child can be prevented from skidding or shaking of the support base 9, and the safety of the cargo handling work can be ensured.

[0014]

As described above, according to the cargo handling apparatus of the present invention, the following effects and advantages can be obtained. (1) Since the guide track of the transport cage is formed by a pair of left and right guide wires wound on a take-up drum on the support stand, and the support stand is movable, the loading and unloading device for vertical loading and unloading is installed and installed. Removal is very easy. (2) The transport cage is guided on a track formed by a pair of left and right guidewires when ascending and descending, so it does not swing during ascending and descending, especially in cargo handling in buildings with narrow narrow entry / exit routes and entrances. Also, there is no possibility that the structure around the route will come into contact with the load. (3) According to the above (1) and (2), labor can be saved, safety can be improved,
The working time can be shortened, and it is particularly effective for cargo handling in ships and buildings having narrow carrying-in / out passages or carrying-in / out entrances.
