Description

Structure assembly equipment and structure assembly method

The present invention relates to an assembly facility for a structure such as a container crane and a method for assembling the structure.

Generally, a container crane used for loading / unloading containers on a ship in a port or the like has a lower structure composed of steel structure legs and an upper structure provided on the lower structure. The superstructure includes a girder and a boom. The girder extends overhanging in the horizontal direction with respect to the lower structure. The boom is provided on the extension line of the girder. Further, the boom is provided so as to be able to tilt upward.

Such container cranes are assembled in a factory on the land, separate from the installation site.
Some container cranes have a height of 40 m, for example. If an attempt is made to assemble such a large container crane in a factory, a very large assembly crane facility is required in the factory. However, in terms of maintenance costs and installation costs, it is difficult to provide a large assembly crane facility in a factory.

Therefore, in the factory, the lower structure and the upper structure of the container crane are assembled separately. The upper structure is lifted using a large crane ship (floating crane) at the assembly plant and joined to the lower structure. Thus, a container crane is completed by joining an upper structure to a lower structure. Thereafter, the completed container crane is transported by being mounted on a barge or the like to a port or the like as an installation place. The container crane transported to the installation site is lifted again by a large crane ship and installed.

The boom 16 can be tilted upward. In the figure, reference numeral “18” denotes a machine room or an electric room.

Next, a container assembly facility (structure assembly facility) 20A for assembling the container crane 10 will be described.
FIG. 2 is a diagram illustrating the configuration of the container assembly facility 20A in this embodiment. FIG. 3 is a diagram illustrating a state in which the barge 23 is levitated in the container assembly facility 20A.
As illustrated in FIG. 2, the container assembly facility 20A includes a first floor (first region) F1 and a second floor (second region) F2 having different heights.

An assembly crane (crane) 22 is installed on the first floor F1. As the assembling crane 22, for example, a so-called jib crane including a turning portion 22b and a hoisting arm 22c on a column 22a can be used.

The second floor F2 is formed at a lower height than the first floor F1. The second floor F2 is formed by, for example, a concave pit 21 formed by excavating a part of the first floor F1 downward. The bottom surface 21b of the pit 21 is the second floor F2. The pits 21 forming the second floor F2 can communicate with a river, the sea, etc. via a sluice (not shown). Water can be introduced into the pit 21 from the outside by a pump (not shown) or the like, and water can be discharged to the outside.

On the second floor F2, a barge (conveyance unit, floating body) 23 which is a floating body capable of floating on the water surface is installed. As shown in FIG. 3, the barge 23 has a size and a buoyancy that can float on the water surface in a state where the container crane 10 in a completed state is mounted. The barge 23 can tow the external water area with a tow ship (not shown) in a state where the container crane 10 in a completed state is mounted. Thereby, the barge 23 can convey the completed container crane 10 to an external water area.

Next, an assembly method and an installation method of the container crane 10 in the container assembly facility 20A described above will be described with reference to FIG. FIG. 4 is a diagram showing the flow of the assembly method and the installation method of the container crane 10 in this embodiment.

First, as shown in FIG. 2, the container crane 10 is assembled on the barge 23 provided on the second floor F2 by the assembly crane 22 provided on the first floor F1 (assembly process: step S101).
At this time, the container crane 10 assembled on the barge 23 is fixed to the upper surface 23a of the barge 23 via a lashing material 25 such as a wire rope or a temporary steel angle material.

Next, the assembled container crane 10 is conveyed outside the second floor F2 by the barge 23 (conveying step: step S102).
At this time, as shown in FIG. 3, water is introduced into the pit 21 from the outside. Then, the barge 23 carrying the container crane 10 floats on the water. After the water surface in the pit 21 is at the same level as the external water area (not shown), a water gate (not shown) is opened to communicate the inside of the pit 21 with the external water area.
Thereafter, the barge 23 is pulled by a tow boat (not shown), and the container crane 10 is transported to a harbor near a predetermined installation location.

When the barge 23 carrying the container crane 10 is transported to the harbor near the installation location, the barge 23 is brought into contact with the quay. Then, the tying material 25 is unwound and the container crane 10 is released from being fixed to the barge 23 (installation step: step S103).
Next, the container crane 10 is moved from the barge 23 to the quay. At this time, the container crane 10 can be easily moved to the quay if a rail is installed on both the barge 23 and the quay. Thereafter, the container crane 10 is moved to a predetermined installation location. Thereby, the installation of the container crane 10 is completed.

Therefore, according to the container crane assembly facility 20A and the container crane 10 assembly method of the first embodiment described above, the assembly of the container crane 10 is assembled on the first floor F1 higher than the second floor F2. This can be carried out using the crane 22 for use. Therefore, it is possible to use a small crane having a small lifting lift for the assembling crane 22.
In addition, after the container crane 10 is assembled on the barge 23, the completed container crane 10 can be transported to the outside while being placed on the barge 23, so that the container crane 10 can be efficiently transported from the assembly to the container crane 10. be able to.
Furthermore, since the container crane 10 can be assembled without using a crane ship, it is not affected by the influence of the weather or the schedule of the crane ship side. Moreover, the assembly work of the container crane 10 can be smoothly advanced. Furthermore, the cost of renting a crane ship is unnecessary, and the cost can be reduced.
As a result, even a large container crane 10 can be assembled smoothly at low cost.

Here, the container ship assembling facility 20A can use an existing shipyard equipped with a pit 21 and an assembling crane 22. Thereby, equipment cost can be suppressed to the minimum. This also makes it possible to make effective use of shipyards with low operating rates and shipyards that are no longer used.

Further, the container crane 10 is assembled on the barge 23, and the container crane 10 in the completed state is transported on the barge 23 as it is, so that the container crane 10 can be efficiently transported from the assembly. It becomes possible.

In the first embodiment, a jib crane is used as the assembling crane 22. However, the present invention is not limited to this. FIG. 5 is a view showing a modified example of the container crane assembly facility 10A according to the first embodiment.
As shown in FIG. 5, a so-called portal crane can be used as the assembling crane 22. The portal crane in this modification includes

support columns

22d and 22d provided on both sides of the pit 21, and ceiling rails 22e installed on the

support columns

22d and 22d.

Next, a structure assembly facility and a structure assembly method according to the second embodiment of the present invention will be described. In the description of the second embodiment, components that are the same as those in the first embodiment are denoted by the same reference numerals in the drawing and description thereof is omitted. FIG. 6 is a view showing a method for assembling the container crane assembly facility 20B and the container crane 10 according to this embodiment.
As shown in FIG. 6, the container crane assembly facility (structure assembly facility) 20B has a first floor (first region) F11 and a second floor (second region) F12 having different heights.
An assembly crane 22 is installed on the first floor F11.
The second floor F12 is formed at a lower height than the first floor F11. In this embodiment, the first floor F11 is, for example, the ground surface. The second floor F12 can be formed by excavating the ground surface, for example.
An inclined surface Fs is formed between the second floor F12 and the first floor F11 so as to gradually increase from the second floor F12 toward the first floor F11.

In such a container crane assembly facility 20B, a cart 50 on which the container crane 10 can be mounted is used. The carriage 50 includes a base portion 51 on which the container crane 10 is mounted, and a plurality of wheels 52 provided on the lower surface of the base portion 51. The carriage 50 may be provided with a drive source so as to be able to run on its own, or may be driven by being pulled by another towing vehicle or the like.

Next, a method for assembling the container crane 10 in the container crane assembly facility 20B described above will be described. The assembly method of the container crane 10 in this embodiment has the assembly process (step S101), the conveyance process (step S102), and the installation process (step S103) shown in FIG. 4 as in the first embodiment. . Therefore, the description about the assembly method of the container crane 10 in the container crane assembly facility 20B will be described with reference to FIG.

First, the container crane 10 is assembled on the cart 50 provided on the second floor F12 by the assembly crane 22 provided on the first floor F11 (assembly process: step S101).
At this time, it is preferable that the container crane 10 assembled on the carriage 50 is fixed to the carriage 50 via the lashing material 25.

Next, the container crane 10 assembled on the carriage 50 is conveyed to the outside of the second floor F12 by the carriage 50 (conveying step: step S102). For this purpose, the carriage 50 on which the container crane 10 in a completed state is mounted is moved from the second floor F12 to the first floor F11 via the inclined surface Fs by a towing vehicle (not shown) or a winch.
Thereafter, the container crane 10 is placed on a barge or a transport ship from the first floor F11 and is transported to a port near the installation location of the container crane 10. At this time, the container crane 10 may be placed on a barge or a transport ship while being placed on the carriage 50, or only the container crane 10 may be placed on a barge or a transport ship.

When the container crane 10 is transported to the harbor near the installation site, the container crane 10 is moved from the barge or the transport ship to the quay. Thereafter, the container crane 10 is moved to a predetermined installation location along the rails laid on the quay (installation step: step S103). Thereby, the installation of the container crane 10 is completed.

Therefore, according to the container crane assembly facility 20B and the container crane 10 assembly method of the second embodiment described above, the assembly of the container crane 10 is assembled on the first floor F11 higher than the second floor F12. This can be carried out using the crane 22 for use. Therefore, as with the first embodiment, even a large container crane 10 can be assembled smoothly at low cost. *

Further, after the assembly of the container crane 10 is performed on the carriage 50, the completed container crane 10 can be transported to the outside while being mounted on the carriage 50 as it is. Therefore, the container crane 10 can be efficiently transported from assembling.

In the second embodiment, the first floor F11 is set at the ground level and the second floor F12 is set lower than that. However, the present invention is not limited to this. For example, the second floor F12 may be set to the same level as the ground surface, and the first floor F11 may be installed on a higher ground, a bank, or various structures. In this case, the inclined surface Fs is not provided, and the first floor F11 can be directly mounted on a barge or a transport ship. As a result, it is not necessary for the cart 50 on which the container crane 10 is mounted to climb the inclined surface Fs. Therefore, the completed container crane 10 can be transported more efficiently.

The present invention is not limited to the configuration of each of the embodiments described above, and the design can be changed without departing from the gist thereof.
For example, the configuration of the container crane 10 is not limited to the configuration of each embodiment described above.
Furthermore, in each said embodiment, although the container crane 10 was made into assembly object, it is not restricted to this. For example, the present invention can be similarly applied to various large structures installed in a harbor or the like.

Further, after the container

crane assembly facilities

20A and 20B are carried out, the container crane 10 may be transported to the installation place by any means.

The assembly of the structure is performed using a crane provided in the first region higher than the second region, and after the structure is assembled on the transport unit, the completed structure is placed on the transport unit. By carrying it outside, it is possible to carry out assembly work smoothly at low cost even with a large container crane.
