Description

[Detailed description of the invention] The present invention relates to a purge lifting device.

In general, the methods used for sea transportation include container ships, rush ships, barges, etc., and purge lines and purge integrators. Although the latter method is very advantageous in these respects, it requires a large amount of equipment costs for port facilities such as wharves, and therefore there are restrictions on the unit of cargo. In some cases, if the purge is left floating in the water for a long period of time in the port before or after departure, the contents may spill into the water due to damage to the purge due to wind or wave effects or other causes. There is a risk of pollution and damage to nearby coastlines.

In order to avoid this, methods such as making the purge itself have a structure that can withstand wind waves and collisions, or placing it in an enclosure while floating in the water to prevent spillage from leaking outside can be considered.

However, not only is it not economical to strengthen the barge itself or install a special enclosure, but it is also far from perfect in terms of safety, so the most advantageous and safest option is to move the purge itself to a suitable location on land. .

The present invention is based on this basic idea and aims to provide a device that can easily and safely carry out purge.

In order to achieve this purpose, in the present invention, a slope is formed on the land where the purge is docked, and running wheels are attached to the purge, and the purge with the running wheels is pulled by a traction device such as a winch on land or water. By pulling the purge from the front and rear directions and lifting it along the slope while restraining the purge from moving in the horizontal direction, the work can be easily carried out without using a large crane. The structure is designed to prevent the Purge from repeatedly rising rapidly and landing on the bottom due to waves rushing in when it first touches the slope or when it is about to leave the slope.

In other words, the anti-land side of the purge is made heavier, and a float is used to normally keep the purge horizontal, and when the purge lands on the bottom with a buoyancy damping device, the buoyancy is sufficiently reduced while it is floating, and the purge sinks, thereby preventing drooling. Even if the buoyancy increases as the boat gets deeper, the gravity is sufficiently greater to allow it to reach the bottom completely.
It is designed so that it cannot resurface even if a wave hits.

The invention will be further explained below with reference to embodiments shown in the accompanying drawings.

Figures 1a and 1c are overall explanatory diagrams of the purge landing device of the present invention, in which a barge 1 has running wheels 2 and 3 attached to the bottom, and pull rings 4 and 5 at the front and rear near the upper end of the barge 1. ing.

Wire ropes 6 and 7 are passed through the pull rings 4 and 5, respectively, to restrain horizontal movement of the barge 1, and the opposite end of the wire rope 6 is connected to a winch 8 installed on land.
The opposite end of the wire 7 is attached to a tensioning device (not shown).

The barge 1 further includes a float 9, and the side on which the float 9 is provided is made heavier, and the barge 1 normally remains horizontal due to the buoyancy of the float 9.

The float 9 also has a large diameter valve 10 and a drain valve 11, as shown in FIG.

In order to make the work easier, the land where the barge 1 is berthed, landed on the bottom, and landed is at least at a depth that allows the barge 1 to reach the bottom with its running wheels 2 and 3 without being completely submerged in water from the flat part 12 on land. A slope 14 is formed that continues below the water surface 13 to the bottom of the water.

Therefore, after landing on the bottom, the barge 1 can easily unload by winding up the wire rope 6 with the winch 8 and letting out the same length of wire rope 7, traveling along the slope 14 with the running wheels 2 and 3. The purge landing operation will be performed in the following steps:

First, in the state shown in FIG. 1a, the barge 1 floats on the water surface 13 and is pulled from the front and back by the wire ropes 6 and 7 passed through the pull rings 4 and 5, restraining its movement in the horizontal direction. There is.

In this state, fully open the large diameter valve 10 of the float 9 and
By filling the barge with water and eliminating its buoyancy, the barge 1 lands on the slope 14 as shown in FIG. 1b.

In that case, water is poured into float 9 to eliminate the buoyancy, but even if the force to sink is not enough during the process, barge 1 takes time to sink, so it is still floating, and slope 1
4, the barge 1 will not repeatedly collide with the slope 14 even if the water surface 13 rises and falls due to waves and the barge 1 moves up and down.

Then, barge 1 gradually sinks and loses sufficient buoyancy when it hits the bottom, so even if the water surface 13 goes up and down due to wave action, barge 1 calmly hits the bottom once on slope 14. .

Thereafter, as shown in FIG. 1C, while loosening the wire rope 7, wind up the wire rope 6 with the winch 8.
The barge 1 travels on a slope 14 with running wheels 2 and 3, is pulled up onto the water surface 13, and is landed on a flat section 12 connected to the slope 14.

Although not shown, the float 9 may be provided as a ballast tank in a part of the barge 1.

Further, instead of the wire ropes 6, 1, another tensioning means such as a chain may be used.

Furthermore, in order to further facilitate the bottoming of the slope 14 on which the barge 1 bottoms, the bottom landing portion may be formed into a horizontal portion 15 as shown in FIG.

In the device of the present invention, as described above, the purge is restrained from the front and back by ropes, so that the purge is not swayed horizontally when landing, and can be accurately and smoothly moved to the landing site.

Further, since the bottom of the purge on the opposite land side lands on the slope by the buoyancy damping device, the purge can be landed smoothly along the slope.

Therefore, the purge landing device of the present invention has the great effect of being less susceptible to the influence of waves when unloading purge from the sea, and less susceptible to the influence of currents when unloading purge from a river.

As described above, according to the present invention, the purge can be landed from the surface of the water very easily and simply, and there is no fear that the purge will be hit against the water bottom by waves during the operation, so the operation can be carried out safely and reliably. This provides various excellent effects such as eliminating the risk of water contamination due to spillage of contents.
