Abstract

PURPOSE:To enable a ship to safely sail through a narrow channel, and to satisfy a canal rule, by connecting the floor section and ceiling section around a steering unit with each other through a transparent member to form a capsule, and by elevatably arranging the capsule. CONSTITUTION:A transparent cylindrical member 8 for storing therein a capsule 6 is arranged in the attaching section of the capsule 6 in a steering cab 1, having the lower end extended to a ceiling liner 17 in an accommodation space below the steering cab 1. Racks 9 are attached to opposite side surfaces of the cylindrical member 8, and pinions 10 adapted to mesh with the racks 9, and gears 11 and motors 12 for rotating the pinions 10 are arranged below a floor surface 3 of the capsule 6. A cable 15 for sending signals to various equipments is extended from a space below a steering stand 14, and an excess length part of the cable 15 is stored in a cable storage 16. Further, if the capsule 6 is moved to a raised position, it is possible to see a point P even through loaded cargo 20 is left as it is. Thereby it is possible to safely sail the ship even through a narrow canal and to satisfy a canal rule.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a bridge structure for ships that can be raised as necessary to ensure visibility for ships passing through narrow passages such as canals. be.

[Conventional technology]

In modern cargo ships, the bridge is generally built at the rear of the ship, while in bulk carriers, for example, the bridge is located at the rear of the ship.
As shown in the figure, many have an upper deck configured to carry cargo such as containers or wood on a hatch cover.

[Problem that the invention seeks to solve]

As a result, the visibility from the wheelhouse l is obstructed by the cargo 2o, and when passing through the canal, the visibility conditions stipulated in the canal regulations (to be able to see through point P in Figure 6) are required. .

It was uneconomical to remove the cargo () or carry more paralast than necessary to ensure the safety of the aircraft.

[Means for solving problems]

The present invention has been made to solve these problems, and is characterized in that a capsule is formed by connecting the floor and ceiling parts around the steering device with a see-through body, and the capsule is provided so as to be movable up and down. It is said that

What is encapsulated is the area around the steering gear, and it is only necessary that it has the minimum equipment needed to maneuver the ship. The floor and ceiling are connected by a see-through material such as a transparent acrylic plate or glass plate.

Since this capsule is normally arranged in a steering room, it is desirable that the entire wall surface be formed of a transparent material.

However, the see-through body only needs to be used within a range where the driver can secure the field of vision, and therefore, for example, the lower half portion may be formed of a steel plate or the like. The capsule may be rectangular, cylindrical or elliptical. This capsule will have an entrance and exit, but will also have windows, ventilation holes, etc. as appropriate. As a means for raising and lowering the capsule, a rack and a binion may be used, or the capsule may be lifted with a wire or the like. In order to prevent the capsule from becoming unstable in the raised position, measures such as supporting the capsule by providing a pedestal or providing a frame on the bridge so that the capsule fits within it in the raised position Take the following steps.

There may be only one steering device inside the capsule, but one steering device may also be provided outside the capsule so that they can be switched between each other, so that the steering device outside the capsule is normally used.

The present invention can be widely used in ships that sometimes use narrow passages. Narrow roads can be of any type, including canals, rivers, waterways, and straits.

[Function] By raising the capsule containing the steering device, the driver's field of view can be secured and steering can be performed reliably.

〔Example〕

FIG. 1 is a side view showing an overview of the area around the bridge, which is an embodiment of the present invention, and FIG. 2 is a plan view thereof. Also,
FIG. 3 is a cross-sectional view taken along the line A-A in FIG. 1, and FIG. 4 is a cross-sectional view of the vicinity of the rack portion. Figure 5 shows a side view of the entire ship.

As shown in FIGS. 1 and 2, a capsule 6 is formed by connecting a floor 3 and a ceiling 4 around a steering device 2 in a wheelhouse 1 with a transparent body 5. As shown in FIGS. A sliding door 7 is attached to the back of the capsule 6.

A transparent cylindrical body 8 for accommodating the capsule is provided at the attachment site of the capsule 6 in the wheelhouse 1. The lower end of the cylindrical body 8 reaches the ceiling lining 17 of the living area below the wheelhouse 1. As shown in FIGS. 2 and 3, racks 9 are attached to approximately the center of both sides of the cylinder 8 in the longitudinal direction of the cylinder. A pinio/10 that meshes with the rack 9, a drive gear 11 that rotates the pinion 10, and a motor 12 are attached thereto. As shown in FIG. 4, a guide rail is attached parallel to the rack 9 to prevent the capsule 6 from moving laterally. A cable 15 for sending signals to each device extends from below the steering stand 14, and its excess length is stored in a cable locker 16 and further extends from there to connect to each device. The ceiling portion 4 of the capsule 6 has a flange 18 at its peripheral edge, and is configured so that when the capsule 6 is in the lowered position, the flange contacts the upper edge of the cylinder 8 via a waterproof gasket 19 to make it waterproof. .

〔Effect of the invention〕

When the capsule 6 is moved to the raised position, as shown in FIG.
It is possible to see through points, enable safe navigation in narrow passages, and satisfy canal regulations.
