BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo handling apparatus, and more particularly to a cargo handling apparatus suitable for use in cargo handling work in a ship having a cargo room in which powder particles such as gravel are mounted.

[0002]

2. Description of the Related Art Conventionally, in ships carrying powdered and granular materials,
Some are equipped with a cargo handling device for unloading and unloading powdery or granular materials. This device is generally constituted by a crane device, and a grab bucket which is lifted and lowered by a crane cable is moved between a luggage compartment and a land facility to unload or unload it. Cranes are often installed on the hull before and after the luggage compartment along the center of the hull in order to balance the hull.

[0003]

However, in the conventional glove bucket type cargo handling device using a crane, since the grab bucket is moved up and down via a cable, a lot of time is required for hoisting the cable and the work efficiency is improved. It had the drawback of being very bad. In particular, there is a problem that the excavation by the grab bucket is unstable and the loading amount of the bucket is not constant. In addition, since the crane has props fixed to the hull, it is necessary to move the bucket over a wide range, and external factors due to the shaking of the hull also add, making it extremely difficult for the operator to move to the intended location, Not only was there a stability problem, but there was the risk of collision damage to the walls of the luggage compartment.

In view of the above conventional problems, the present invention is capable of performing a reliable operation according to the operator's intention while avoiding the influence of the sway of the hull and greatly improving the work efficiency. The purpose is to provide.

[0005]

In order to achieve the above object, a ship handling apparatus according to the present invention is a ship handling apparatus for carrying and transporting powdered particles and the like, which straddles a cargo room opening of the ship. A bridge is provided, and a hydraulic excavator main body is rotatably attached to the bridge to enable cargo handling by a bucket.

[0006] The second ship handling apparatus is a ship handling apparatus for carrying and transporting powdered particles and the like, and a bridge is provided across the cargo room opening of the ship, and the bridge is connected to the cargo room opening surface. It is possible to run along, and a hydraulic excavator main body is attached to the bridge so that it can be swung, and loading and unloading with buckets is possible.

Further, in the second ship handling apparatus,
A hopper was attached to the outer end of the bridge, and a conveyor was installed on the deck of the ship along the movement path of the hopper so that it could be carried out.

[0008] A fourth ship handling apparatus is a ship handling apparatus for carrying and carrying powdered particles and the like, wherein a bridge is provided across the cargo room opening of the ship, and the bridge extends along the cargo room opening surface. It is capable of traveling, and a traverse carriage is attached to this bridge, and a hydraulic excavator main body is pivotably attached to this traverse carriage so that cargo can be handled by a bucket.

Further, in this case, a hopper is attached to the traverse carriage, a belt conveyor is installed in the bridge, and the discharge end of the belt conveyor is made to face a transfer conveyor installed on a ship deck. be able to.

[0010]

According to the first aspect of the invention, the hydraulic excavator main body can be attached to the bridge attached to the opening of the cargo compartment of the ship, and the granular material in the cargo compartment can be unloaded by the bucket operation. Therefore, a so-called backhoe type unloading work device can be provided, and the bucket can be driven and operated at a location intended by the operator. Since the bucket does not use a cable as a medium, the bucket is not affected by the shaking of the hull, and the occurrence of an accident that damages the hull can be suppressed.

In the second aspect of the invention, since the bridge can be moved along the opening surface of the luggage compartment, the working range of the hydraulic excavator mounted on the bridging is greatly expanded, and the working machine has a wide arm even when the arm is short. A work area can be secured, and cargo can be handled by a small hydraulic excavator.

In the third structure, a hopper is attached to the outer end of the movable bridge, and a cargo is loaded into the hopper by the bucket. The hopper can move above the transport conveyor installed on the side of the deck. Conveyor transportation of goods can be realized,
Since the cargo is not spilled, the work efficiency can be improved.

In the fourth device configuration, since a traverse vehicle is further attached to the bridge which can move along the opening of the cargo handling room and the hydraulic excavator is mounted on the cart, the hydraulic excavator can be arranged in any so-called XY plane. You can move. As a result, the moving range is remarkably expanded, and a large amount of work can be performed by a small shovel. If the traverse truck is equipped with a hopper so that cargo can be loaded, and if it can be transported to the conveyor on the deck by the belt conveyor provided at the bridge, the hydraulic excavator body can be sufficiently handled as a small excavator. The cargo handling efficiency can be improved without increasing the weight.

As shown in these drawings, the cargo handling apparatus of the embodiment is installed in a ship 10, and is installed in an opening portion of a cargo room 12 that is formed in the ship 10 and in which a powdered material such as gravel is put. This is provided with traveling rails 16 laid on the deck along both sides of the luggage compartment opening 14, and a movable bridge 18 capable of traveling in the front-rear direction of the ship 10 with the traveling rail 16 as a guide track straddles the luggage compartment opening 14. It is installed in. The traveling bridge 18 is provided with traveling wheel portions 20 at both ends thereof. For example, the traveling bridge portion 18 is provided with wheels that are driven by a hydraulic motor with a planetary gear speed reduction mechanism as a power source, and can be arbitrarily moved along the traveling rail 16. As a drive system, a rack and pinion drive system or the like may be used.

A hydraulic excavator main body 22 is mounted at a substantially central portion of the moving bridge 18. The hydraulic excavator main body 22 has a structural state in which the traveling frame portion of a general hydraulic excavator is removed and the excavator main body 22 is attached to the moving bridge 18 in place of the traveling frame portion. That is, a drive source mounting portion 24 is rotatably mounted on the moving bridge 18, a multi-joint arm 26 having a proximal end pivotally attached to the drive source mounting portion 24 is attached, and a bucket 28 is provided at the tip of the arm 26. The bucket 28 can be moved to an arbitrary position in the vertical direction by the undulating drive of 26 so that the cargo handling work can be performed. This allows
The hydraulic excavator main body 22 operates the arm 26 and the bucket 28 by the operation of the operator in the operator's cab 30 formed in the drive source mounting portion 24, and the granular material in the luggage compartment 12 within the swing operation range of the drive source mounting portion 24. It is possible to unload cargo. Then, the movable bridge 18 is moved and moved with respect to the cargo room 12 in a wide range, whereby the cargo handling position is changed, and the shovel cargo handling in the entire area is enabled.

By the way, it is necessary to transport the powdered or granular material loaded by the hydraulic excavator main body 22 to the land side. Therefore, a transport conveyor 32 is installed on one side of the deck of the ship 10. This is a normal belt conveyor, which is installed longer than the length of the luggage compartment 12 and extends toward the bow side so that it can be supplied to the transportation equipment on the land side. A hopper 34 is attached to an end portion of the moving bridge 18 in order to transfer the cargo handling soil and the like by the hydraulic excavator main body 22 onto the transport conveyor 32.

The difference is that the hydraulic excavator main body 22 is mounted on the traverse vehicle 36. As a result, the hydraulic excavator main body 22 can be moved in the front-rear direction of the hull and in the width direction of the ship on the luggage compartment opening 14, and so-called XY plane movement is possible. As the hydraulic excavator main body 22 is made movable in a plane, the unloading goods are transferred to the ship-side transfer conveyor 32.
A traverse belt conveyor 38 is installed on the moving bridge 18 and a hopper 40 is attached to the traverse carriage 36 that moves along the conveyor 38 so as to be discharged. The hydraulic excavator main body 22 pays out to the hopper 40, and the traverse belt conveyor 38 conveys it to the ship side conveyor 32.
I am going to carry it to the side. Traverse belt conveyor 38
The discharge end of is located at the upper part of the ship-side transfer conveyor 32 and moves along with the bridge 18, but in order to ensure transfer, a chute 42 is attached to the end of the bridge 18 to transfer the conveyed product from the transverse conveyor 38. After being received by the chute 42, the chute 42 is made to drop on the ship-side transfer conveyor 32.

The second embodiment as described above is particularly effective when the width dimension of the luggage compartment 12 of the ship 10 is large. Further, the hydraulic excavator main body 22 of the bridge fixing type of the first embodiment
In the second embodiment, the excavation effective range is expanded, so that the work efficiency is increased.

In the above embodiment, the hydraulic excavator main body 22 can be moved by the moving bridge 18 or the traverse carriage 36. However, when the luggage compartment 12 is small, the bridge 1
