Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating pier connected to a quay by a connecting bridge, and more particularly, to a mooring of a ship and a carrier used for unloading and moving passengers between the ship and the quay. It relates to a floating pier with equipment.

[0002]

2. Description of the Related Art Mooring facilities for carrying cargo by mooring and mooring ships include mooring piers, piers, and floating piers. Because these quays are made in consideration of safety during storm surges, they are high for small fishing boats and small ferry vessels and are not suitable for cargo handling work and passenger getting on and off. Due to the ebb and flow of the tide, the relative position between the mooring shore and the fishing boat or ferry,
In particular, since the height changes, there is a problem that the efficiency of cargo handling work is reduced in a fishing boat or the like, and that a trouble occurs when a passenger gets on or off a ferry boat or the like.

In addition, mooring piers and piers require large-scale marine work such as reclamation and construction of a firm quay, and thus cannot be easily constructed.

On the other hand, a floating pier in this mooring facility is constructed by mooring a floating body serving as a pier with a mooring pile or the like fixed to the sea floor and providing a connecting bridge between the pier and a large-scale marine work. Because it is not required, it is often used in fishing ports and harbors.

Since the floating pier follows the ebb and flow of the tide, the relative height between the mooring boat and the deck surface of the floating pier is maintained substantially constant regardless of the ebb and flow of the tide.
This is very advantageous for unloading work.

In addition, the crews of these small fishing boats and the like are of an aging age, and if the height difference is large when unloading the caught fish to the quay, the work becomes difficult. It is expected that a floating jetty that can maintain the height difference of the river approximately constant.

In the prior art, the transfer of luggage between the floating pier and the quay is carried out by human power using a trolley or the like, or by a vehicle for unloading and transporting a forklift or a truck entering the floating pier. It is carried out using a cargo handling device or a transport device such as a belt conveyor carried on a floating pier. Passengers on the ferry are moving on foot from the pier to the quay.

Further, in fishing ports, etc., due to the fact that pickling is carried out in the morning market held on the quay etc., unloading is concentrated and it is necessary to discharge efficiently in a short time. In short, cargo handling and transport are often performed over short distances.

[0009]

In the floating pier, however, the movement between the ship and the deck surface of the floating pier is easy without any change in the up and down because both rise and fall with the water surface. There is a change in elevation between the pier and the quay due to the ebb and flow of the tide, and the floating body of the floating pier moves by waves, which is not always easy.

[0010] For this reason, transportation by human power requires power and is inefficient in work efficiency. Moreover, it is difficult to secure human resources and the aging of fishermen is progressing. Improvement is desired.

[0011] In addition, the loading and unloading of the vehicle for unloading and occupying the work place on the narrow pier alone reduces the work efficiency. Work to lift to the loading platform, move the vehicle to the quay, and then unload, transport from the loading platform of the transport vehicle, or transfer the cargo to another large transport vehicle, etc. There is a problem that it is not reduced and the workability is poor.

Further, when using a conveyor such as a belt conveyor carried on a floating pier, if the conveying device is left as it is on the pier, the conveying surface of the conveying device is higher than the deck surface of the floating pier. As a result, a step is created between the deck surface and the transport surface, so that it is necessary to further lift the unloading cargo containing the landed fish etc. on the deck surface and to unload the cargo from the transport surface at the quay. Occurs.

[0013] The unloading and unloading of these boxes must be performed manually, and these boxes can weigh as much as 70 kg, resulting in heavy labor and severe work for aging fishermen. There is.

Further, since the transfer device carried on the deck of the floating pier is occupied exclusively, there is a problem that the workable area is reduced.

[0015] In addition, the unloading work is temporary, and after unloading, maintenance of the fishing gear and fishing gear is performed on the pier. Therefore, before and after the unloading work, the transfer device is moved from the quay to the floating pier or from the floating pier. Installation and removal work to move to the quay is required. In addition, it is necessary to secure a place for storing the transport device on the quay.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to reduce the amount of unloading and unloading a load to reduce labor during the unloading operation and to improve work efficiency. It is another object of the present invention to provide a floating pier with a transport device that can use the entire deck surface when unloading work is not performed.

[0017]

A floating pier with a transfer device according to the present invention is configured as follows.

1) A floating pier connected to a quay by a connecting bridge, wherein a transport device for placing and moving a load or a person on a transport surface is incorporated in a deck of a floating body forming the floating pier. In addition, at least at the time of transport, the transport surface of the transport device is formed to be substantially the same height as the deck surface of the floating body.

This transport device is formed by a belt conveyor, rollers, or the like, and has a transport surface substantially at the same level as the deck surface, and is incorporated in a floating deck.

The substantially same height, or substantially the same level, means that the load can be slid and moved laterally, and the load can be lifted up a little to move the load onto the transporting device at a slight angle. In addition, even if a vehicle or the like rides on the vehicle, it means that the vehicle is not so far as to be able to operate the vehicle without such discomfort.

The conveyor such as the belt conveyor and the rollers is installed in the deck of the floating body of the floating pier, and the conveying surface and the deck surface of the conveyor are substantially at the same level, so that the deck surface from the ship can be lowered. Since the height of unloading and unloading the load is small, and there is substantially no step between the deck surface and the transfer surface, the load can be moved on the transfer device by sliding and laterally moving the load. As a result, workability in cargo handling can be significantly improved, and labor can be reduced.

Even when the cargo handling operation is not performed, the transport surface is substantially the same height as the deck surface.
The entire deck surface can be used without obstructing traffic of people or vehicles.

In addition, this transporting device transports a load in a cargo handling operation, but is not limited to the load.
It may be a conveyor for moving passengers such as a tourist boat or an escalator for horizontal movement.

Even when the passenger is moved, since there is substantially no step with the deck surface, the passenger can be safely transferred to the transport surface, and can move together with baggage placed on the transport surface. In addition, when the passenger is not using the apparatus, the transport device can be stopped and the entire deck surface can be used, so that the vehicle does not become a hindrance, and the cargo handling work and the replenishment work for the ship can be performed efficiently.

The transport device incorporated in the deck has a transport surface substantially at the same height as the deck surface only during use.
When not in use, lower it a little and put a lid on it,
The surface after the lid may be formed so as to be flush with the deck surface. In particular, when a roller is used, it is easy to slip.

When the passenger is to be moved, it is preferable that the handrail is of a foldable type or a vertically movable type so that the handrail can be used on one side only during transportation.

2) In this floating pier with a transport device,
The transport device is formed by a belt conveyor or a roller.

As the transport device, in addition to the belt conveyor and the roller, a group of carts having the upper surface as a transport surface, a floating device by blowing out an air jet, and the like can be considered. Suitable for the transport device of the invention.

In the case of a belt conveyor, the belt conveyor is driven by an electric wire drawn from the quay, a driving force obtained by an engine for driving the belt conveyor, etc., to convey a load and to move a person. .

In the case of a roller, a load is placed on a freely rotating roller, and the load is conveyed by pushing or pulling the load with human power or a winch. When this roller is used, no special driving force is required, and the structure is simple, so that the cost is reduced.

3) In the floating pier with a transport device described above, a connecting portion between the connecting bridge and a floating body connected to the connecting bridge, or a bridge bridge between the floating bodies and the floating body, A connecting portion between the floating body connected to the bridge and the bridge has a plurality of transport rollers, and is provided with a telescopic roller device in which the transport surface of the rollers is formed to be extendable.

The use of the telescopic roller device can absorb the change in the vertical distance even at the connecting portion where the vertical distance is likely to change due to the movement of the floating body. By being pushed, it easily moves to the next transporting device, so in this connection part,
There is no need to transfer the load.

4) Further, in the floating pier with a transport device described above, a branch roller having a transport surface substantially at the same height as the deck surface of the floating body between the floating device and the mooring portion of the floating body. The device is provided and configured.

With this configuration, the unloading from the ship moored on the floating pier is placed on the branch roller device,
It can be easily moved and placed on the transfer device.

5) As a method of improving the existing floating pier to provide a floating pier with a transport device according to the present invention, in the case of a floating pier connected to a quay by a connecting bridge, luggage or persons are placed on the deck surface of the floating pier. And a method of raising the deck surface of the floating body so as to be substantially the same height as the transfer surface of the transfer device.

According to the method of improving the existing floating pier, the existing floating pier can be relatively easily changed to the floating pier with the transport device of the present invention.
