Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an in-hold cargo handling device, and in particular, an in-hold cargo handling device used for transporting cargo carried into a cargo hold to a desired location and stacking or transshipping it. Regarding equipment.

[Prior Art] Cargo ships that transport frozen cargo and the like are generally equipped with cargo handling equipment such as an overhead crane in their holds.

However, because there are normally a number of columns, etc., arranged in an orderly manner within the hold, it has been difficult to handle cargo within the entire area of the hold using a single overhead crane.

For this reason, in the past, a large number of relatively small overhead cranes were installed within the hold within a range where they did not interfere with the supports, etc., thereby making it possible to handle cargo throughout the entire area within the hold.

[Problems to be Solved by the Invention] However, installing a large number of cargo handling devices in a hold increases the area occupied by the cargo handling devices, which has the drawback of limiting the amount of cargo that can be loaded.

As shown in Japanese Utility Model Application No. 60-117381, a girder is provided on the hatch coaming on the deck so that it can be moved back and forth, and a mast is installed on this girder so that it can be moved left and right and up and down. A cargo handling device equipped with a horizontally movable fork has been proposed, but the structure of moving the fork up and down by the entire height inside the hold increases the size and cost of the device.

Therefore, the present invention was devised to solve the problems of the conventional technology, and its purpose is to make it small enough to handle cargo within the entire range of the cargo hold, increase the amount of cargo loaded, and reduce costs. It is an object of the present invention to provide an in-ship cargo handling device that can reduce the amount of waste.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a girder that is hung across the center of the ceiling in the hold and runs in the ship's direction, and a girder that is approximately the same length as the girder. a shuttle beam formed in the girder and movably supported along the longitudinal direction at the bottom of the girder and extending to the ship's side; a trolley supported so as to be movable laterally along the shuttle beam; The present invention is characterized by comprising an elevator having a hanging beam which is horizontally rotatable and extends horizontally from one side of the elevator so as to be freely raised and lowered, and a hanging load member which is suspended from the hanging beam and supports a load.

[Function] The girder that runs in the ship's direction and the shuttle beam that extends in the ship's width direction prevent the trolley from interfering with the pillars, etc. that stand in the hold, and cover the entire area in the ship's ship and width directions near the ceiling inside the hold. It becomes possible to move freely over the period. Since the load suspended from the hanging beam of the elevator provided on the trolley via the hanging load member can be raised and lowered by raising and lowering the hanging beam, it is possible to easily carry out cargo handling operations throughout the entire area in the hold.

[Example] An example of the present invention will be described below in detail based on the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a hold of a cargo ship, the ceiling of which is covered with a deck 2, and a hatch 4 for carrying in and out cargo 3 is formed approximately in the center of the deck 2. There is no intermediate deck inside Craft 1, so it can be used widely. Inside the boat 1, there are pillars 5 for supporting the deck 2 from the bottom (not shown).
They are located on both sides of the ship and are spaced apart in the longitudinal direction.

A pair of rails 6 are provided on the inner side of the pillars 5 near the ceiling (deck 2) facing each other in the width direction of the ship.
is stretched continuously in the longitudinal direction, and a girder 8 having wheels 7 at both ends that roll on the respective rails 6 is stretched between both rails 6.

A rack 9 is attached to the side surface between the rails 6, and a pinion 10 that meshes with the rack 9 is rotatably supported at both ends of the girder 8 by a travel motor 11 and a rotating shaft 12. It is now ready to run.

The tops of two upper and lower guide grooves 14 and 15 formed on both sides of the shuttle beam 13, which has approximately the same length as the girder, are engaged with the guide groove 14 at both ends and the center of the girder 8. A support roller 16 is provided which extends and supports the beam 13 from the lower surface of the girder 8 along its longitudinal direction to the ship's side so as to be movable. The shuttle beam 13 passes between the struts 5 arranged at intervals in the ship's ship direction, and moves in one direction or the other in the ship width direction. In order to move the shuttle beam 13, a rack 17 is attached to the upper surface of the shuttle beam 13 along its longitudinal direction as shown in FIG. 2, and a pinion 18 that meshes with the rack 17 is attached to the girder 8. A moving motor 19 is installed.

A trolley 21 equipped with wheels 20 that engages with lower guide grooves 15 on both sides of the shuttle beam 13 is suspended and supported along the girder 8 so as to be freely traverseable, and a lift having a suspension beam 22 that can be freely raised and lowered is provided at the lower part of the trolley 21. 23 is attached so that it can freely rotate horizontally. The trolley 21 includes a traverse drive section 24 that drives traverse wheels 20 and a swing drive section 25 that drives the elevator 23 to swing.

A lifting guide 2 is provided on one side of the main body 26 of the elevator 23.
7 is mounted so as to be tiltable via a shaft 28, and the lifting guide 27 can be tilted by a cylinder 29. The cylinder 3 is installed in the lifting guide 27.
A lifting frame 30 that is lifted and lowered by the lift frame 1 is supported, and a hanging beam 22 is attached to the lifting frame 30 so as to extend horizontally. On the upper surface of the hanging beam 22, as shown in FIG. 4, there is a hanging load member 33 for hanging a load 32.
Pins 36 are attached to hang the hanging strings 35 at the four corners of the motsuko 34 constituting the. In addition,
A plurality of replacement holes 37 for pins 36 are formed on the upper surface of the hanging beam 22 so that the slackness of the hanging string 35 can be adjusted.

When carrying out cargo handling in the lower part of the boat 1, as shown in FIG. It is adapted to be hung with a hanging string 35. Auxiliary hanging cord 39 in this case
Similarly to the motsuko 34, the hanging load member 33 is configured.

Next, the operation of the device will be described. When carrying out cargo handling in the lower part of the boat 1, as shown in FIGS. 1 and 3, the auxiliary suspension cord 39 is tied to the suspension beam 22 of the elevator 23 and suspended, and the suspension cord 3 of the motsuko 34 wrapped around the cargo 32 is suspended.
5 on the hook 38 of the auxiliary hanging cord 39. The load 32 is lifted and lowered by raising and lowering the hanging beam 22, and the load 32 is moved by running the girder 8, extending the shuttle beam 13, moving the trolley 21 laterally, and turning the elevator 23. Since the loads 3 are stacked one by one across the entire range from the bottom of the boat 1, the auxiliary hanging cord 39 can be replaced with a shorter one each time one stack is stacked.

When the loads 32 are stacked up to a height where the hanging string 35 of the motsuko 34 reaches the pin 36 of the hanging beam 22, the hanging string 35 of the motsuko 34 is directly connected to the pin 36 of the hanging beam 22 without using the auxiliary hanging string 39.
Transport it by hooking it on. Since the hanging beam 22 can be moved up and down to near the ceiling inside the boat 1, it is possible to stack the cargo 32 sufficiently high.

As described above, although the hanging beam 22 is provided on the ceiling of the boat 1, cargo handling in the height direction can be easily carried out, and the structure differs from the conventional device in which the forks are raised and lowered by the entire height of the boat 1. It is possible to achieve simplification, reduction in size and weight, and reduction in cost.

Note that the driving means for driving the girder 8, extending the shuttle beam 13, and moving the trolley 21 horizontally are not limited to those in the embodiment. shuttle beam 1
3, guide grooves are provided on both sides of the girder 8, and wheels that engage with both guide grooves are provided on the shuttle beam 13, so that the shuttle beam 13 is suspended and supported. Good too. In order to prevent deflection of the shuttle beam 13, a large number of the wheels may be provided with narrower intervals.

In addition, in order to automatically and mechanically take up the slack in the suspension string 35 of the motsuko 34, a guide 40 is installed along the diagonal direction of the suspension beam 22 as shown in FIGS. 5 and 6.
The movable body 41 may be provided movably through the movable body 41, and a moving cylinder 42 may be connected to the movable body 41, respectively, and a hook 43 for hooking the suspension string 35 of the motsuko 34 may be attached to the movable body 41.

In addition, in order to assist with the lifting work, the elevator main body 2
A winch or the like may be attached to 6.

[Effects of the invention] In summary, the present invention provides the following excellent effects.

(1) A shuttle beam that extends and moves in the ship's width direction is installed on the girder that runs in the ship's direction, and an elevator that has a hanging beam that can be raised and lowered is installed on a trolley that is supported by the shuttle beam so that it can freely rotate. , the elevator can be freely moved over the entire area near the ceiling in the hold in the captain's direction and in the ship's width direction without interfering with the pillars and the like that stand in the hold.

(2) In addition, since cargo handling is carried out by suspending the load from the hanging load member suspended from the hanging beam of the elevator, unlike conventional cargo handling equipment in which the fork is moved up and down the entire height within the hold, the structure is simplified, It is possible to reduce the size and weight of the device, reduce the cost, and increase the amount of cargo that can be loaded.
