DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a cargo handling device,
For example, the present invention relates to a cargo handling device suitable for ships and plants having vertical and narrow loading / unloading ports and loading / unloading routes.

[0002]

2. Description of the Related Art Conventionally, cargo handling work in a place having a vertical loading / unloading port and loading / unloading route has been performed mainly by temporarily installing a hoist, and hoisting and hoisting a load by the hoist.

[0003]

By the way, in a place having a vertical loading / unloading port and loading / unloading route, when a hoist is temporarily installed to carry out lifting and lowering of luggage, if the loading / unloading port and route are narrow, However, there is a possibility that the luggage may swing around due to the shaking of the hull or the like and the influence of the wind, and the luggage may come into contact with the structure around the loading / unloading port and the loading / unloading route, which is a problem in terms of safety and luggage protection. In addition, it takes time and labor to install and transfer the hoist, which causes a problem in labor saving and speeding up of the work. The present invention seeks to solve such problems.

[0004]

SUMMARY OF THE INVENTION In a cargo handling apparatus according to the present invention, a support base, a winding drum rotatably attached to the support base and driven to rotate by a motor, and a hoist attached to the support base are provided. , A transport cage hung on the hoist, a pair of left and right guide wires wound on the winding drum, and weights that are attached to the lower end portions of the guide wires and can be installed on the floor surface. A predetermined tension is applied to each of the guide wires by adjusting the torque of the motor, and the guide wires form an elevating guide track of the transport cage, which is a means for solving the problem.

Further, in the cargo handling apparatus of the present invention, a wheel and a stopper are attached to the support frame to solve the problem.

In the cargo handling apparatus of the present invention, the weight connected to the pair of left and right guide wires is installed on the floor surface by using the winding drum rotatably attached to the support frame, and a predetermined tension is applied to the guide wires. The load is loaded and unloaded by raising and lowering the transport cage using this guide wire as a guide track for raising and lowering the transport cage. The raising and lowering of the transport cage is operated by the hoist fixed to the support base,
The lifting and lowering of the weight and the tension adjustment 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 in place by a tosper,
It can be used by moving to various loading / unloading ports.

BEST MODE FOR CARRYING OUT THE INVENTION A cargo handling apparatus as an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view thereof.

In this embodiment, a ship such as a submersible vessel in which narrow carry-in / carry-out ports are vertically arranged over a plurality of stages, and each carry-in / carry-out port is connected to form a vertical and narrow carry-in / carry-out path. Reference numeral 101 indicates a deck, reference numeral 102 indicates a middle deck, and reference numeral 103 indicates a floor surface. While the loading / unloading port 104 is formed on the deck 101,
The loading / unloading port 10 is vertically below the loading / unloading port 104 on the central deck 102.
5 are formed. A support frame 9 is arranged so as to surround the carry-in / out port 104 on the deck 101.

The support pedestal 9 has a main body 90 formed by four pillars in a substantially square shape in a plan view, four leg members 91 hung vertically at each of four corners of the main body 90, and the main body 90. It is composed of a pair of left and right columns 92 planted in the central portion, and stoppers 10 and wheels 11 are attached to the lower ends of the leg members 91, respectively. Therefore, the support base 9 can be easily moved to any place on the deck 101 and can be fixed to that place (by operating the stopper 10).
The motor 3 is attached to one of the columns 92. Further, the take-up drum 2 whose base end (the left end in FIG. 1) is connected to the rotation shaft of the motor 3 is rotatably supported at the other end by the other end 92 (the right end in FIG. 1). There is.

A pair of left and right guide wires 1 are wound around the winding drum 2, and each guide wire 1
A weight (weight) 5 is attached to the lower end of the. Therefore, the weight 5 can be moved up and down by rotating the winding drum 2 using the motor 3 as a drive source. Then, the weight 5 is placed on the floor 103,
Moreover, 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 is applied form the guide rail for the elevator cage 6. Reference numeral 6 indicates a transportation cage capable of accommodating transportation luggage, and on both left and right side surfaces of the transportation cage 6,
A pair of guide rollers 7 rolling on the guide wire 1 are attached. Further, a hoist 4 for raising and lowering the transport cage 6 is attached to a support base 9.
Reference numeral 93 indicates a mounting member for supporting the hoist 4. Further, reference numeral 8 indicates a pulley with a hook suspended from the wire 41 of the hoist 4.

At the four corners above the transport cage 6, a hanging wire that can be engaged with and disengaged from a pulley 8 with a hook of the hoist 4.
61 are attached respectively. In the above 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 a track are given tension, and the guide rollers 7 roll along the two left and right guide wires 1 that are in tension when tension is applied when the transport cage 6 is moved up and down. Therefore, it is possible to prevent the transport cage 6 from rolling laterally when the transport cage 6 is moved up and down, and it is possible to safely carry in and out the luggage in the narrow space.

The ascending / descending speed of the transport cage 6 is adjusted by operating the hoist 4. Also, two guide wires 1
Finely adjust the torque of the motor 3 so that the weight 5 does not sway or skid, and the two guide wires 1 have a tension force that can prevent the transport cage 6 from rolling. , Its tension is adjusted. The support base 9 includes a main body 90, leg members 91, and columns 92.
Since each is made of a columnar member, it is formed into a lightweight yet highly rigid structure, and the wheels (casters) 11 are attached to the lower end portions of the leg members 91, respectively, so that they can be easily moved. Can be made. In addition, the stoppers 10 attached to the lower ends of the leg members 91, respectively.
Thus, the support base 9 can be fixed at a predetermined position, so that the support base 9 can be prevented from slipping and shaking, and the cargo handling work can be secured.

[0014]

As described in detail above, according to the cargo handling apparatus of the present invention, the following effects and advantages can be obtained. (1) The guide rail of the transport cage is formed by a pair of left and right guide wires that are wound around the take-up drum on the support rack, and the support rack is movable, so installation and installation of a cargo handling device for vertical loading and unloading Removal is extremely easy. (2) Since the transport cage is guided by the track formed by a pair of left and right guide wires when moving up and down, it does not sway during elevating and lowering. Also, there is no risk that the structure around the route will come into contact with the luggage. (3) By the above (1) and (2), labor saving of work, improvement of safety,
The working time can be shortened, and it is particularly effective for loading and unloading of ships and structures having a narrow loading / unloading passage or loading / unloading entrance.
