Description

[Detailed description of the invention] The present invention relates to a floating trolley used when a structure such as a ship floating on the sea is pulled up to land or lowered from land to sea. The purpose of the present invention is to provide something that can perform the work and can sufficiently deal with the strength of the ground at the site of lifting and lowering.

Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, reference numeral 1 denotes a floating truck according to the present invention, and this truck 1 includes a truck body 3 having a ballast tank 2, and running wheels 4 provided at the bottom of the truck body 3. It consists of a fixing device 5 and a roller device 6 provided on the upper part of the truck body 3, and connecting devices 1 are provided on the front and rear surfaces and both left and right sides of the truck body 3.

The truck 1 can float and sink by pouring water into the ballast tank 2, and is made of steel or concrete.

The running wheels 4 can be ordinary wheels or low-pressure tires (iron wheels, etc. can be used. Usually, only the support shaft is provided at the bottom of the trolley body 3, and the appropriate wheels 4 are selected according to the usage environment. and install it.

The fixing device 5 can be raised and lowered around the horizontal axis, and is composed of a hook member or a regular rod-shaped member that can be held against the bottom surface of the structure.

Further, the roller device 6 has a large number of trochanters rotatably supported by support shafts arranged in parallel in the longitudinal direction of the truck body 3.

Note that instead of configuring the fixing device 5 to be able to be stored inside the truck body 3 as described above, the fixing device 5 and the roller device 6 may be provided on the truck body 3 in a removable manner.

Next, the effect will be explained.

Several trolleys 1 are used in combination as appropriate depending on the size and weight of the structure 8A8B to be lifted or lowered.

When a ship 8A floating on the sea is towed to land, it is advisable to arrange a plurality of units (three units in the drawing) in two rows in the longitudinal direction of the vessel 8A, as shown in FIG. 5, for example.

The bogies 1 are connected to each other on land, and are connected to each other by coupling devices 7 on the front and rear surfaces and both left and right sides of the bogie body 3,
This is floated on the sea, seawater is injected into the ballast tank 2, and it is submerged in the sea.

Next, the vessel 8A is moved and positioned above the truck 1.

In this case, the tip of the lobe 9, which is not connected to a land winch (not shown), is fixed to the truck 1 in advance.

The positioning may be performed by moving the ship 8A as described above, or by moving the truck 1 with a winch, or vice versa.In order to further facilitate positioning, the positioning may be performed by moving the ship 8A on the sea from the truck 1. It is desirable to set the pole 10 upright.

After completing the positioning in this way, the ballast tank 2
The seawater is drained to float the truck 1, and the fixing device 5 or the roller device 6 provided on the upper part of the truck body is pressed against the bottom surface of the ship 8A.

Seawater is poured into the ballast tank 2 by a support vessel 11 via a water injection hose 12.

If the ground at the salvage site is solid, the fixing device 5 is brought into pressure contact with the bottom of the ship, and if it is soft, the roller device 6 is brought into pressure contact.

FIG. 3 shows the case of lifting on solid ground 13. With the fixing device 5 in pressure contact with the bottom of the ship, the winch pulls the bogie 1 to the land side via the lobes 9, and continues pulling the bogie 1. The winch is hoisted so that the wheels 4 of the machine run on the salvaged ground 13.

In this way, the ship 8A is pulled up from the sea to land while being held on the trolley 1.

Figure 4 shows the case of lifting over soft ground 15.
In this case, the fixing device 5 is stored in the truck body 3 as shown by the imaginary line in FIG. 1, and the roller device 6 is brought into pressure contact with the bottom surface of the vessel 8A as the truck 1 floats.

In this state (FIG. 2), the winch is reeled in and the trolley 1 is pulled through the rope 9 to a position on the soft ground 15 where it can be salvaged.

Next, the tip of the lobe 9 is removed from the truck 1 and fixed to the ship 8A side.

Thereafter, when the winch is retracted and the ship 8A is pulled, the ship 8A moves on the roller device 6 of the truck 1 and is pulled up.

In this case, by sequentially sending the auxiliary cart IAY to the lower side of the salvage route of the ship 8A, as shown by the imaginary line in FIG. 4, it becomes possible to salvage the ship 2.1 to the destination location.

This auxiliary truck 1A can use another winch to send in a truck that has been cut off from the ship 8A as the ship 8A moves.

The reason for doing this is that if the salvaged ground 15 is soft, the running wheels 4 of the trolley 1 will be buried in the ground due to the weight of the ship 8A, making it impossible to run.

In such a case, the tip of the rope 9 may be fixed to the ship 8A from the beginning and the ship 8A may be pulled.

The above has explained the case of withdrawing from the sea to land, but conversely, when withdrawing from land to sea, the procedure is the reverse, and since it is self-evident that there is no need to explain it, details will be omitted.

Furthermore, even if the structure is something other than a ship 8B, its lifting and lowering can be carried out using the same procedure.

FIG. 6 shows the arrangement of the truck 1 with respect to a structure 8B other than a ship.

In this case, since the bottom surface shape of the structure 8B is rectangular, three carts 1 are interconnected vertically and horizontally to match the shape.

The present invention can be carried out as described above, and with such a floating trolley, it is extremely easy to lift up and lower structures between the sea and land, and it is also possible to carry out the work of lifting up and lowering structures between the sea and land. Since it can sufficiently cope with the situation, it becomes possible to carry out lifting and lowering operations not only at docks but also in a wide range of locations.

In addition, since connecting devices with other truck bodies are provided on the front and rear surfaces and both left and right sides of the truck body, a plurality of truck bodies can be connected in the front and rear and left and right directions depending on the size of the ship or the like.
