Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bridge structure for a ship, and more particularly to a bridge structure suitable for a pilot or the like to monitor the vicinity of the water surface directly below the ship's side.

Generally, a bridge is installed as a superstructure on the upper deck of a ship, and it is possible to monitor the surroundings of the ship from this bridge, but in recent years, the automation of ship operation has progressed, and the wheelhouse has become smaller. In order to reduce hull resistance based on the wind pressure that the bridge receives and to reduce weight, the width of the bridge has become significantly narrower than the width of the ship. .

Therefore, as shown in Figure 1, a wing b is provided that extends sideways from the bridge a, and monitoring is carried out at the side end of the wing.However, if the wing b is long, it may receive wind pressure. Furthermore, if the wing b is short, there is a problem in that the vicinity of the water surface directly below the side C cannot be monitored.

The present invention attempts to solve these problems by providing a monitoring box on the bridge of a ship that can be moved to the side and extended only when monitoring the vicinity of the ship's side. without causing any problems,
It is an object of the present invention to provide a bridge structure for a ship that can be sufficiently monitored from the inside of the box to just below the side of the ship when monitoring the ship.

Therefore, the bridge structure for a ship according to the present invention includes a bridge as an upper structure provided on the upper deck of the hull, and the bridge has a width narrower than the width of the upper deck of the hull, The bridge is formed so that its centers are aligned with each other, and an elongated running platform is attached to the back of the upper part of the bridge that can selectively run toward port or starboard. A monitoring box that can travel in the same direction in synchronization with the traveling of the traveling platform is attached, and the box is provided with an entrance and exit communicating with the inside of the bridge and a monitoring window.

Further, in the ship bridge structure of the present invention, a plurality of support rollers that support the lower surface of the frame fixed along the lower surface of the traveling platform and a plurality of guide rollers that guide the side surface of the frame are arranged on the bridge, respectively. The box is characterized in that a traveling roller and a lateral displacement regulating roller, which are arranged in a row and engage with a rail along the traveling platform, are respectively attached to the lower part of the box.

Hereinafter, a bridge structure of a ship as an embodiment of the present invention will be explained with reference to the drawings. Fig. 2 is a perspective view showing its main parts, and Figs. 3 and 4 show its running platform and monitoring box. FIG.

As shown in Fig. 2, a bridge 3 as an upper structure is erected on the upper deck 1 of the hull via the stern deck 2, and the width of the bridge 3 is wider than the width of the upper deck 1 of the hull. They are also narrow and are formed so that the centers of their widths are aligned.

Therefore, the frontal wind pressure area of the bridge 3 is reduced, which reduces hull resistance based on wind pressure during navigation, reduces the burden on the main engine, and contributes to fuel savings.

However, the side surface 3a of the bridge 3 is significantly recessed inward than the side 1a, and the sea surface directly below the side 1a cannot be monitored from the cabin inside the bridge 3. Therefore, in the bridge structure of the present invention, the bridge 3 is provided with a running platform 4 that can selectively move toward the port side or the starboard side, and a monitoring box 4a that can move in the same direction in synchronization with the running of this running platform 4. There is.

The carriage 4 has an elongated shape in its running direction, and a box 4a located at the center of the carriage 4 in its neutral position in the left-right running direction has an entrance 6 that communicates with an entrance 5 of a cabin in the bridge 3. In addition, monitoring windows 7 and 8 are provided at the top of the box 4a.

A pair of frames 9 having a U-shaped cross section are fixed along the lower surface of the carriage 4, and a number of support rollers 10 supporting the lower surface of the lower bent edges 9a of these frames 9 are attached to the exposed deck 3b of the bridge 3. arranged in rows at the top.

(See Figures 3 and 4) Furthermore, on this exposed deck 3b,
As shown in FIGS. 2 and 4, a large number of guide rollers 11 that guide the side surfaces of each frame 9 are arranged in a row via brackets N1a, and as shown in FIGS. A stopper roller 1 for preventing its left end from tilting downward when it protrudes toward the port side as shown in figure 4'.
2, a support member 12 is attached to the port side portion on the exposed deck 3b.
Similarly, a stopper roller 13 for when the carriage 4 protrudes toward the starboard side is disposed via a support member 13a on the exposed deck 3b on the starboard side. The stopper rollers 12 and 13 engage with the upper surface of the lower bent edge 9a of the frame 9.

The means for regulating the limit of the protrusion of the carriage 4 in the side direction include a stopper plate 14.15 protruding from the upper part of each support member 12a, 13a, and a projection piece 14a protruding from the outer surface of the carriage 4. , 15a, and the traveling platform 4 is the second
When protruding toward the port side as indicated by the chain line 4' in the figure, the stopper plate 14 fixed to the support member 12 receives the protruding piece 14a of the carriage 4 to restrict the protrusion limit, and the carriage 4 is When protruding toward the starboard side, the protrusion limit is similarly regulated by receiving the protruding piece 15a of the carriage 4 with the stopper plate 15 of the support member 13a.

As a mechanism for guiding the movement of the monitoring box 4a, as shown in FIGS.
The running roller 16 and the lateral displacement regulating roller 1 that engage with b
7 are respectively attached to the lower part of the box 4a.

A rack and pinion system is used to drive and run the traveling platform 4, and the casing 18 on the exposed deck 3b
A pinion 19 rotated by a motor (not shown) installed inside the rack 20 attached to the running base 4
Although the driving platform 4 is driven to travel by engaging with the winch, the driving platform 4 may be driven to travel by a combination of a winch-operated wire and a pulley instead. good.

A rack and pinion system is used as a means for driving and running the monitoring box 4a, and as shown in FIGS. 2 and 4, a motor 21 installed inside the box 4a is used.
The pinion 22 rotated by the box 4a engages with the rack 23 attached to the carriage 4.
Drive running is performed.

The motor 21 in the box 4a is operated in synchronization with a motor (not shown) in the casing 18 by means of an appropriate electric circuit, so that when the traveling platform 4 starts traveling, for example, toward the port side. , when the box 4a also starts to travel in the port direction on the traveling platform 4, and the traveling platform 4 travels to the limit in the port direction and stops, the box 4a also travels to the limit in the port direction and stops. ing.

Also, when the traveling platform 4 travels toward the starboard side, the box 4a operates in synchronization with the traveling of the traveling platform 4 in the same manner as when traveling toward the port side described above.

Note that the limit of movement of the box 4a in the starboard direction is regulated by the lateral displacement regulating roller 17 coming into contact with the inside of the end frame 4c of the carriage 4.

Since the bridge structure of the ship of the present invention is configured as described above, for example, when the ship enters port, the pilot can easily transfer from the cabin in the bridge 3 to the monitoring box 4a through the entrances and exits 5 and 6. can box 4
By operating the control device (not shown) in box 4a,
By controlling the motor 21 inside the casing 18 and remotely controlling the motor inside the casing 18, the traveling base 4 and the box 4a can be selectively moved and projected toward the port side or the starboard side.

At this time, since the box 4a travels in synchronization with the travel of the traveling platform 4, compared to the case where the box 4a starts traveling after the traveling platform 4 completes traveling,
This has the advantage of shortening the time required to set the box 4a in the use position.

Then, from the monitoring windows 7 and 8 of the box 4a,
It is possible to sufficiently monitor areas near the water surface directly under the water.

In this way, when the pilot has monitored one side and then continues to monitor the other side, the pilot operates the control device while riding on the same box 4a to control the running platform. There is an advantage that the box 4a can be quickly moved along with the box 4a to the other side, and the monitoring work can be continued efficiently.

Furthermore, when the box 4a is not in use, the box 4a and the traveling platform 4 can be stored in a neutral position in the left-right travel direction as shown by the solid line in Fig. 2 to avoid wind damage. This can contribute to reducing hull resistance.

As described in detail above, according to the bridge structure for a ship according to the present invention, an elongated running platform is attached to the bridge in the running direction that can selectively run toward the port side or the starboard side. A monitoring box that can run in the same direction in synchronization with the movement of the traveling platform is installed along the bridge, and the box is equipped with an entrance and exit that communicates with the bridge and a monitoring window, so it cannot be used for monitoring at all times. The boxes and carriages are stored in neutral positions to reduce hull resistance caused by wind pressure, and when passing through narrow channels or entering or exiting port, the monitoring boxes and carriages are moved out to provide sufficient visibility for monitoring. This makes it possible to secure this.

Further, a plurality of support rollers that support the lower surface of the frame fixed along the lower surface of the traveling platform and a plurality of guide rollers that guide the side surfaces of the frame are respectively arranged in rows on the bridge, and Since the traveling rollers and the lateral displacement regulating rollers that engage with the rails along the platform are respectively attached to the lower part of the box, the advantage is that the box and the traveling platform can be driven extremely smoothly and safely. be.

Further, according to the ship bridge structure of the present invention, when a pilot on board a box on the bridge conducts surveillance on one side and then on the other side, the pilot, while remaining on the same box, without the need to transfer
Monitoring work can be carried out, and since the box and the traveling platform 4 on which it is mounted run in synchronization, the box can be quickly moved to the side, which allows for efficient monitoring work. There are advantages.
