Description

[Detailed Description of the Invention] The present invention relates to a self-propelled turning device for a shore ramp provided on a car carrier or the like.

Conventionally, the ship's rampway, which is used when transporting cars to and from transport ships, is taken out from its storage location and suspended with a rope fed out from a deck crane, and -i is connected to the tongue table installed in the ship's side opening, and other The end is slanted and spans over the quay, and cars run on this rampway.

However, it is necessary for the rampway to be sequentially rotated in its installation direction in response to changes in the loading and unloading of automobiles gathered near the quay.

In addition, the car carrier moves up and down due to the tidal difference, and the slope of the rampway changes, so in order to maintain the slope angle, the rampway must be moved in the same way as above.

However, due to changes in the loading and unloading of cars or the mooring equipment of the carrier ship, it takes a lot of manpower and time to turn and move the long ramp to the required position each time using the deck crane on the ship or the jib crane on the quay side. At the same time, the reach of the crane was often insufficient, reducing functionality and work efficiency when loading and unloading automobiles.

The present invention was developed in view of the above points, and it is possible to quickly and easily position a long rampway installation device that spans between a car carrier and a quay in response to changes in the direction of vehicles being carried in and out near the quay. To provide a self-propelled turning device for a shore rampway that can turn and move to.

Hereinafter, one implementation ψ11 of the present invention will be explained based on the drawings.

FIG. 1 is a cross-sectional view showing the entire system, and 1 shows the hull of a car carrier moored at a quay 2. Inside the cargo hold 3 of the hull 1, a multi-tiered car deck 4 is constructed using well-known technology. Ramp 5 installed between each deck 4 for moving cars up and down
This is provided.

Further, a rectangular opening 6 through which a car enters and exits is formed at a suitable location on at least one side of the hull 1, and a door 7 whose base end is connected to a hinge and can be opened and closed in the vertical direction is provided at the upper edge of this opening 6.
is attached to the lower edge of the opening 6, and a tongue table 10 is provided at the lower edge of the opening 6, the base end of which is supported by a bracket 8 that extends to the ship's side shell plate, and the other end of which is fitted with an engaging fitting 9. The tongue table 10 has a wire robe let out from a winch (not shown) or the like on the upper deck 11 and is secured to the side thereof so that it can be raised and lowered by the winch.

Further, a rampway 12 is removably connected to the tip of the tongue table 10 via an engaging fitting 9.

To explain the lathe @A of the rampway 12 that connects to the car carrier that has been intercepted as described above with reference to FIGS. The rampway 12 is made up of a body 13 and a striped steel plate 14 stretched over its upper surface, and one end of the rampway 12 is connected to a tongue table 10 via an engagement fitting 9, and the other end is connected to the frame 13 at the bottom of the striped steel plate 14. A plurality of motor-driven reduction gears 16 are provided on mounts 15 mounted at symmetrical positions on both ends in the width direction, and a sprocket wheel 18 is pivotally supported at the end of the drive shaft 17 of the reduction gears 16. .

Further, a plurality of rollers 21 and a sprocket wheel 22 supported by a horizontal shaft 20 are attached to the center of a rectangular support frame 19 installed in parallel with the motor-driven speed reducer 16. Sprocket wheel 18 on the machine 16 side and sprocket wheel 2 on the roller 21 side
A roller chain 23 is wound between the two.

Furthermore, as shown in FIG. 3, the roller lifting device B has an upright screw shaft 25 on the outer frame body 19a of the roller 21 which is pivotally supported in the center of the support frame 19.
is attached, and a guide hardware 26 is attached to the center of this screw shaft 25.
, and the above roller 21 is attached to the top of the screw shaft 25.
A fitting part 28 is provided for inserting a box spanner 27 used during lifting and lowering operations.

Further, a portable control box 24 for starting and stopping the rollers 21 is connected to the motor-driven speed reducer 16.

Power to the motor-driven speed reducer 16 is supplied from a predetermined power source of the car carrier through an electric wire cord running along the rampway.

The present invention has the above-described configuration, and when the rampway 12 spanning between the car carrier and the quay is self-propelled and turns in a desired direction, first, a plurality of When a box spanner 27 is inserted into the upper end fitting portion 28 of both screw shafts 25.25 erected outside the support frame 19 at the bottom of the rectangular frame 13 and rotated clockwise, both end screw shafts 25 , 25 are guide hardware 26, respectively.
A support frame 19 descends through the screw shaft 25 and is connected to the screw shaft 25.
Both rollers 2L21 supported on the horizontal shaft 20 are pushed down and ground on the quay wall 2, respectively.

Next, when the switch of the control box 24 connected to the driving prime mover installed adjacent to the roller 21, that is, the motor-driven reducer 16° 16 on both sides installed on the frame 15 at the bottom of the frame 13, is turned on, the above-mentioned deceleration occurs. machine 16,16
A sprocket wheel 18 attached to the 0-axis end and a sprocket wheel 2 pivotally supported on the side of the roller 2L21.
By the guiding force of the lobe chain 23q wound between the two rollers 2L21, both rollers 2L21 rotate at the same time, and the rampway 12 can be rotated by itself to the desired position.

In addition, when the work of transporting automobiles to the carrier ship via the rampway 12 is completed and the vehicle is stored on the ship, both motor 1 drive reducers 16, 16 are stopped, and the roller 21, 21 support frame 19
The screw shaft 25 connected to the screw shaft 25 is rotated clockwise and in the opposite direction using a box spanner 27 to raise the rollers 21 and 21, respectively, and then stored in a predetermined location on the ship using a deck crane.

A stopper (not shown) attached to the frame 13 is inserted into the upper part of the screw shafts 25, 25 to prevent the screw shaft 25 from moving up and down.

According to the present invention described in the above implementation section, the rampway that spans between the car carrier and the quay can be easily turned and moved according to the direction of loading and unloading of cars on the quay side. Since it is self-propelled and rotates while electrically operated by a motor-driven speed reducer, one-man control becomes more convenient, speeding up the turning function and improving work efficiency.
