Description

[Detailed explanation of the idea] The present invention relates to ship lifter equipment.

For example, when a dam is installed on a waterway, ships cannot pass through it using normal methods.

Therefore, it has been considered to install a counterweight-type lifting equipment in the dam and lift the ship from the upper waterway to the lower waterway, or from the lower waterway to the upper waterway, but with this type of lifting equipment, This method not only requires a heavy counterweight, but also has the problem that one vehicle can only lift or lower one ship at a time.

Therefore, the present invention provides a ship lifter equipment that eliminates such problems.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 is a dam installed between an upper waterway 2 and a lower waterway 3, and a partition wall 1c is provided between both side walls 1a and 1b of this dam 1. From the downstream end of the upper waterway 2 to the upstream end of the lower waterway 3, both waterways 2 and 3 are partitioned into two branch waterways 4a and 4b.

5a and 5b are a pair of vessels arranged on the lower waterway 3 side in each branch waterway 4a and 4b partitioned by the partition wall 1c, and the upstream end and downstream end of each vessel 5a and 5b are An opening/closing door 7.8 is provided at each end.

9 is a machine frame that supports each vessel 5a, 5b; 10 is a vessel lifting device disposed at the upper end of the partition wall 1c;
It has two sets of hoisting drums 11 and a wire rope 13 wound around a sheave 12 suspended from each hoisting drum 11 and supported by the machine frame 9. When one vessel 5a or 5b is hoisted by winding the wire rope 13, the wire rope 13 of the hoisting drum 11 of the other set is unwound so that the other vessel 5b or 5a is hoisted down. be.

Therefore, conventional balance weights are unnecessary.

15 is the end 2 of the upper channel 2 in each branch channel 4a, 4b.
A first gate provided in b, a notch 16 is formed at the center of the upper end of the gate 15, and the notch 16
A U-shaped frame 17 is provided.

When the vessels 5a, 5b are raised to the highest level, the ends of the vessels 5a, 5b are connected to the U-shaped frames 17, and the connection points are kept watertight. .

18 is a second gate provided at an appropriate distance upstream from each first gate 15 in each branch waterway 4a, 4b;
19 is a third gate provided downstream from the end 3a of the lower waterway 3 in each branch waterway 4a, 4b, and 20 is a third gate provided downstream from each third gate 19 in each branch waterway 4at4b. A fourth gate 21 provided at an appropriate distance is an opening/closing device for the gates 15 and 19.

22, 23.24 are the first and second gates 15.24, respectively.
18, between the end 3a of the lower waterway 3 and the third gate 19, and between the third and fourth gates 19 and 20, the water level adjustment device includes a communication passage 25, a valve 26, and a water pressure pump. 27.

28 is a ship 2 arranged on the bottom plate of vessels 5a and 5b.
Reference numeral 9 indicates a support board, and reference numeral 30 indicates a guide rail and vessel 5a fixed to both side walls 1a, lb and partition wall 1c.

5b and a guide roll that is in contact with each of the guide rails.

In this embodiment, the notch 16 of the first gate 15 is completely opened, but the notch 16 may be provided with an opening/closing door.

The operation of the above configuration will be explained.

First, as shown by the dashed line in Figure 2, one branch waterway 4
At step a, one vessel 5a is lowered to the lowest position and submerged in water, and the doors 7 and 8 of this submerged vessel 5a are folded down.

Along with this, the other vessel 5b in the other branch waterway 4b also rises to the highest level and is connected to the U-shaped frame 17 of the first gate 15.

Then, the opening/closing door 7 on the upstream side of the other vessel 5b is folded down.

Next, the third and fourth gates 1 in one branch waterway 4a
After adjusting the maximum water level A or the minimum water position between 9.20 and 20 to match the water level C of the lower waterway 3 using the water level adjustment device 24,
Open the gate 20 and move the ship 29 to the third and fourth gates 19.
．． After closing the fourth gate 20, the third and fourth gates 19 and 20 are opened by the water level adjusting device 24.
The water level between the ends 3a and 3 of the lower waterway 3 is set to the maximum water level A.
This corresponds to the maximum water position between the gate 19 and the gate 19.

Next, the third gate 19 is opened, the vessel 29 is placed between the end 3a of the lower waterway 3 and the third gate 19, and the vessel 29 is brought upward into the submerged vessel 5a as shown by the dashed line in FIG.

Next, both opening and closing doors 7 and 8 of the submerged vessel 5a are erected, and the third gate 19 is closed.

At the same time, in the other branch waterway 4b, in the same manner as in the above case, after making the maximum water level E or the bottom level between the first and second gates 15 and 18 coincide with the water level T of the upper waterway 2, (Note that the lower end of the notch 16 of the first gate 15 is located above the water level T), the second gate 18
is opened to bring the vessel 29 between the first and second gates 15.18, and then after closing the second gate 18, the water level between the first and second gates 15.18 is brought to the maximum water level. Then, the vessel 29 is brought onto the other vessel 5b through the notch 16, and the upstream opening/closing door 7 is erected.

Next, after lowering the water level between the first and second gates 15.18, the vessel lifting device 10 is operated to lower the submerged vessel 5a.
is raised, and the vessel 5b in the highest state is lowered.

In this case, since both vessels 5a and 5b are perfectly balanced, both vessels 5a and 5b can be moved up and down smoothly.

Further, the ships 29 in each of the vessels 5a and 5b are floating on water and resting on the board 28.

Therefore, there is no possibility that the ship 29 will move unexpectedly within each vessel 5a, 5b.

Next, when the submerged vessel 5a rises to the highest point as shown by the two-dot chain line in FIG. 2 and connects to the U-shaped frame 17, the first
, after setting the water level between the second gates 15 and 18 to the maximum water level H, the upstream opening/closing door 7 of this vessel 5a is brought down to move the vessel 29 inside the vessel 5a to the first and second gates 15 and 18.
bring between.

Next, after bringing the water level between the first and second gates 15 and 18 to the water level of the upper waterway 2, the second gate 18 is opened and the vessel 29
All you have to do is sail upstream.

When the vessel 5b is submerged in the other branch waterway 4b, the opening/closing door 7.8 of the vessel 5b is knocked down, the third gate 19 is opened, and the vessel 29 is placed between the third and fourth gates 19, 20. After the third gate 19 is closed, the water level between the third and fourth gates 19 and 20 is lowered to the lower waterway 3.
The water level may be set to 8, then the fourth gate 20 may be opened and the vessel 29 may be sailed downstream.

As described above, according to the ship lifter equipment of the present invention, a pair of vessels for storing ships is provided, and a vessel lifting device is provided which connects both vessels to each other and lowers the other vessel when one vessel is raised. Therefore, both vessels can be raised and lowered in a balanced manner.

Therefore, there is no need for a counterweight as in the conventional case.

It is also capable of raising and lowering Mikasa's ships at the same time, and serves as the equivalent of two ships.

Therefore, the equipment can be made more compact than conventional counterweight type equipment, and is highly economical.
