Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for transporting a plant unit, and more particularly, to a method for transporting a plant unit.
This invention relates to a method of transporting plant units, which is often adopted when constructing a plant in a relatively underdeveloped area.

[Conventional technology]

Generally, when constructing various plants in relatively underdeveloped land,
In order to reduce the amount of on-site construction work, equipment used in plants is pre-assembled into units, which are then transported to the site and installed. This unit was also formed as a purge because it needed to be transported by sea.

More specifically, as shown in Figs. 11 and 12, the plant unit 1 is constructed on a number of boards 2 placed on land (Fig. 11), and after being launched, it is towed or the first
As shown in Figure 2, it is loaded onto a transportation barge 3 and transported to the installation site as required.

By the way, such a plant unit 1 is usually a heavy structure, and therefore, careful work is required when launching it from the construction site, loading it onto the transportation barge 3, and furthermore, transporting it to the installation site after arriving at the site. In particular, it is almost impossible to lift up and transport the plant unit 1 to land after it has arrived at the site.Therefore, conventionally, a bay-shaped pond was generally dug on the coast of the installation site and the plant unit 1 was pulled into the pond and then transported. The method used is to refill the pond and install it. but,
According to this method, there is a risk of water intrusion into Planned Unit 1, and it requires a great deal of time and effort for digging and refilling the ground, resulting in longer construction times and higher construction costs. .

[Purpose of the invention]

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to shorten the installation period by hoisting and transporting large heavy structures to land after they arrive at the site. The goal is to reduce costs.

[Summary of the invention]

To achieve the above-mentioned object, the present invention comprises a transportation trolley in which a large number of wheels are disposed at the lower part of the vehicle body, and a plurality of pedestals each having a board mounted on the upper part thereof which can be moved up and down are arranged in the longitudinal direction. The method for transporting a plant unit is characterized in that at least two of the transport carts are arranged in parallel to form a group of carts, and the plant unit is supported and transferred by the group of carts.

〔Example〕

An embodiment of the method for transporting a plant unit according to the present invention will be described below with reference to FIGS. 1 to 10.

FIG. 1 is a side view of a transfer trolley 4 used in the plant unit transportation method of the present invention, and FIG. 2 is a plan view thereof.

The transfer trolley 4 is provided with a large number of wheels 6 at the bottom of a vehicle body 5,
A plurality of pedestals 7 are arranged at appropriate intervals in the longitudinal direction of the upper part.

This pedestal 7 is connected to a pedestal 8 as shown in FIGS. 3 and 4.
and a board 9 that can be moved up and down. In addition,
If the height for supporting the plant unit on the transfer carriage 4 by the board 9 or the like is sufficient, the pedestal 8 can be omitted.

To be more specific, the board 9 is a trapezoidal board 10. It consists of a chevron board 11, a wedge-shaped board 12, and a rectangular board 13. The trapezoid board 10 is assembled with bolts 14, and the chevron board 11 is assembled with bolts 15. Tighten these bolts 14 or bolts 15, Or, by loosening it, the upper surface of the rectangular board 13 can move up and down.

The transfer carts 4 configured in this way form a group of carts 16 in which at least two of them are parallel to each other, and are transferred to the plant unit 1.
(Figure 5).

Next, a specific transportation method will be explained.

As shown in FIG. 6, the plant unit 1 is constructed on pedestals 17 arranged in a plurality of rows on land at intervals l.

This pedestal 17 is constructed in the same manner as the pedestal 7 provided on the transfer carriage 4 described above.

The pedestals 17 are arranged so that the interval 1 is larger than the width W of the transfer carriage 4. By moving the transfer cart 4.4° to the lower part of the plant unit 1 constructed in this way and loosening the bolts of the pedestal 17, the plant unit 1 is moved to the pedestal 7 provided 4.4° above the transfer cart. It will be supported by

Transfer the plant unit 1 to the quay 20 in the above state,
It is loaded on the transportation barge 18 (FIG. 7). A similar pedestal 19 may be provided on the transportation barge 18 so that the plant unit 1 can be supported by this pedestal 19, but if necessary, the transportation cart 4 may be fixed to the transportation barge 18. Good too.

Thereafter, the transportation barge 18 is transported to the site, and the plant unit 1 is unloaded and transported to the installation site by performing the reverse operation of the loading procedure described above. That is, the transportation barge 18 transferred to the site is ballast-adjusted so that its deck 18' and the quay wall 20a are approximately at the same height, and the bolts of the cradle 19 are loosened to support the plant unit 1 on the transfer trolley 4a. .

Then, this transport trolley 4 is pulled ashore by a wire 21 wound around a winding device (not shown).
Figure 8).

The plant unit 1 landed ashore in this manner is transported to the installation site, and is installed on a previously provided foundation by loosening the bolts of the pedestal 7 on the transport trolley 4.

Note that conventional methods can be used to arrange the foundation and install the plant unit 1.

FIG. 9 shows an example of a method for mounting the plant unit 1 on the transportation barge 18.
The deck is filled with ballast water to keep the water deep, and the deck is 18°
The ballast water is discharged after the plant unit 1 is towed to the top. Of course, if the plant unit 1 is to be unloaded from the transport barge 18, the reverse procedure may be performed.

Furthermore, FIG. 10 shows one implementation when the plant unit 1 is unloaded, and a slope 23 is provided in advance on the quay 22, so that the transfer cart 4 can run on this slope 23. It has become. The plant unit 1 is then set on a transport trolley 4 that has been placed in advance, and is lifted onto land from there.

〔Effect of the invention〕

As explained above, according to the method for transporting a plant unit according to the present invention, a plant unit configured as a heavy structure can be easily landed, transported to an installation site, and installed, so that the plant unit requires relatively little development. This system not only shortens the construction period and costs for plant construction, but also allows the installation site to be selected on land, which eliminates the risk of water intrusion into plant unit 1, among other advantages. have
