If necessary or desirable, a spring or a counterweight that tends to lift the elevating passage 31 so as to offset the tendency of the elevating passage 31 to be heavy and lower is provided, or a mechanism that keeps the tension that winds the rope 38 around the winch 37 (constant). Means for providing an automatic tensioning device).
[0010]
As shown in FIG. 1, a telescopic passage 41 with a telescopic hood is provided at the tip of the elevation passage 31. The telescopic passage 41 is telescopically immersed in the lower or upper surface of the elevating passage 31 so as to protrude. For safety of passengers getting on and off, a step is formed between the upper surface of the elevating passage 31 and the upper surface of the telescopic passage 41. Is formed as small as possible. The length of extension and retraction of the telescopic passage 41 is determined so that it can sufficiently cope with a different length range depending on the partner ship, environmental conditions, and the like.
[0011]
As shown in FIG. 1, an extruding spring 46 is provided between a position below the floor of the elevating passage 31 and a position below the floor of the telescopic passage 41 so as to push the telescopic passage 41 forward (to the right in the drawing). The extruding spring 46 is formed so that there is not much difference in the pushing force between the compressed state and the extended state. In addition, a retracting device (not shown) is provided so that the extension spring 46 can be compressed and retracted toward the front (to the left in the drawing) of the telescopic passage 41. This retraction device may be manual or electric. The retracting device can be released, and when released, the telescopic passage 41 is always pushed forward by the force of the pushing spring 46.
[0012]
As shown in FIG. 1, a movable crossover plate 55 is provided on the upper surface of the distal end portion of the telescopic passage 41 so as to be rotatable in a plane around a rotation shaft 54. A ship side contact plate 56 is attached to the lower surface of the movable transfer plate 55. The width and the protruding length of the ship side contact plate 56 are such that when the ship passenger bridge is bridged over the partner ship 90, it can easily serve to guide the ship to a predetermined position relative to the partner ship 90. Has been determined. Further, a suitable cushion is attached to a surface of the ship side contact plate 56 which abuts on the ship side 96 of the counterpart ship 90 so as not to damage the painting or the like of the ship side 96.
[0013]
Further, as shown in FIG. 1, on both sides of the movable crossover plate 55, fitting portions 53 formed so as to fit with the projecting portions 92 provided on the partner ship 90 are provided. The projecting portion 92 of the partner ship 90 may be a structure such as a column at a port gate (an entrance / exit of the ship), and the fitting portion 53 is made to protrude from both sides of the movable crossover plate 55 so that the fitting portion 53 projects. When it is fitted to the projection 92 by a pin or the like, it is configured to be fixed with a pin or the like so that the mating ship 90 and the movable crossover plate 55 are integrated.
[0014]
Next, the operation of the embodiment shown in FIG. 1 will be described. When this marine passenger boarding bridge is not used, the retractable spring 41 is compressed by a retracting device (not shown) so that the telescopic passage 41 is retracted, and the rope 38 is wound by the winch 37 to move the elevating passage 31 to the uppermost position. lift. As a result, the tip of the movable crossing board 55 is retracted from the quay 16 to the land side, and the ship passenger boarding bridge does not hinder the shore of the ship.
[0015]
When a ship arrives at a shore and crosses the ship passenger boarding bridge to the other ship, first, in FIG. 1, the swivel drive unit 12 drives the swivel movable floor 23 to swivel in a required direction. The ship 90 is located almost above the port gate. Next, the rope 38 is unwound with the winch 37 and the elevating passage 31 is lowered, so that the lower surface of the movable crossover plate 55 is slightly higher than the upper surface of the deck of the partner ship 90. Next, the retracting device (not shown) that is retracting the telescopic passage 41 is loosened. Then, the telescopic passage 41 is pushed forward by the force of the pushing spring 46, and the ship side contact plate 56 on the lower surface of the movable crossover plate 55 contacts the ship side 96 of the other ship 90. At this time, if the direction of the ship side contact plate 56 and the direction of the ship side 96 do not match, the movable transfer plate 55 is naturally pushed around the rotation shaft 54 because the movable transfer plate 55 is pushed forward by the pushing spring 46. And the ship side contact plate 56 comes into contact with the ship side 96 exactly. In this state, the fitting portion 53 is protruded and fitted to the protrusion 92, the rope 38 is loosened, the connection between the turning drive device 12 and the turning movable floor 23 is disconnected, and the horizontal position of the ship passenger boarding bridge is released. I will be able to turn and raise freely. Thus, even if the position and angle of the counterpart ship 90 fluctuate slightly, the ship passenger boarding bridge follows the change, and a reliable bridge state is maintained to ensure safe getting on and off of passengers.
[0016]
When the passenger 90 leaves the port after the passengers get on and off, the fitting portion 53 is retracted into the movable crossover plate 55 to release the fitting with the projection 92 in FIG. Then, the telescopic passage 41 is drawn into the elevating passage 31, the rope 38 is wound by the winch 37, and the elevating passage 31 is lifted up about the elevating shaft 39. As a result, the passenger boarding bridge is completely separated from the partner ship 90 and does not hinder the movement of the partner ship 90.
[0017]
Next, a description will be given of an operation in which the ship passenger boarding bridge follows a change in the position and attitude of the partner ship 90. As shown in FIG. 2 (A), when the other ship 90 moves in the horizontal direction, or when the deck of the other ship 90 moves in the horizontal direction as a result of the roll or the lateral inclination, the telescopic passage 41 extends and retracts. Then, the movable crossing board 55 moves integrally with the deck of the counterpart ship 90, reliably maintaining the connection between the land side and the counterpart ship 90, and fulfills the function of a ship passenger boarding bridge. As shown in FIG. 2 (B), when the deck moves up and down due to the vertical movement of the partner ship 90, or the roll or the lateral inclination, the elevating passage 31 is raised about the elevating shaft 39, so that the ascending is performed. The passage 31, the telescopic passage 41, and the movable crossover plate 55 move up and down, and follow up and down movements of the partner ship 90.
[0018]
As shown in FIG. 2 (C), when the bow direction of the partner ship 90 swings right and left, the movable transfer plate 55 rotates about the rotation shaft 54 so that the movable transfer plate 55 moves relative to the partner ship 90. The relative position is unchanged, and the function of the marine passenger boarding bridge connecting the land and the partner ship 90 can be reliably maintained. In a small ferry boat or the like, the angle at which the bow and sway direction can swing left and right is relatively large as compared to a large ship, but in a conventional ship passenger boarding bridge, the response to the movement of the partner ship 90 as shown in FIG. However, the fitting portion was sometimes damaged. On the other hand, in the marine passenger boarding bridge according to the present invention, the movable crossing plate 55 rotates around the rotation shaft 54, thereby coping with the angle fluctuation of the partner ship 90. It should be noted that the swiveling of the swiveling movable floor 23 cannot cope with a change in the angle of the fitting portion with the boat.
[0019]
As shown in FIG. 2 (D), it was conventionally impossible to cope with the case where the other ship 90 moves back and forth, but in the ship passenger boarding bridge according to the present invention, the turning movable floor 23 turns and the angle is changed. In addition, by changing the angle and changing the angle by rotating the movable transfer plate 55 about the rotation shaft 54, it is possible to cope with the parallel movement without any problem.
[0020]
The movement of the bow line of the counterpart ship 90 changing the angle in the vertical direction is the same as the operation of the conventional one, but in the ship passenger boarding bridge according to the present invention, the ship side contact plate 56 of the movable crossing plate 55 Since it is in contact with the ship side 96 of the partner ship 90, it is possible to reliably prevent the ship passenger boarding bridge from coming off the partner ship 90.
[0021]
In the description of the above embodiment, as shown in FIG. 1B, a configuration in which the extruding spring 46 is provided as a means for pushing the telescopic passage 41 forward has been described. It is also possible to hang it on the boarding bridge and use the downward force of this weight as the pushing force of the telescopic passage 41 via the pulley and the rope. If the pushing-out spring 41 is used as the pushing-out means 41, it becomes compact, but if it is a weight type, it can be pushed out with a constant pushing-out force. Further, instead of or together with the winch 37, an elevating raising means for raising the elevating passage 31 by using a pulley and a rope to lower the weight of the weight (counter weight) may be provided. Further, the fitting means between the movable crossover plate 55 and the counterpart ship 90 may be concave on the ship side and convex on the boarding bridge side.
[0022]
The marine passenger boarding bridge according to the present invention is not limited to those described in the drawings and the description of the embodiments, and various changes can be made without departing from the gist of the present invention.
[0023]
【The invention's effect】
As described above, according to the present invention, the rotation provided at the distal end of the telescopic passage against the fluctuation of the position or posture of the counterpart vessel such as the change in the left-right angle or the back-and-forth movement, which was conventionally impossible. Since the movable crossover plate that can cope with such changes in angle and position, there is no danger of breakage or detachment of the fitting part with the partner ship, and it is possible to secure the connection securely and secure passenger safety. It can contribute to getting on and off.
