Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for separately transporting, assembling, and installing a large condenser for a steam engine installed in a power plant, etc., and a condenser suitable for carrying out the above method. It concerns the structure of water vessels.

The large condenser is approximately 20m long, 10m wide, and approximately height
Since it is 20 meters long and weighs approximately 1,000 tons, it cannot be transported on public roads unless it is disassembled and transported from the manufacturing plant to the installation site.

Construction methods for divided transportation that have been commonly used in the past can be roughly divided into panel construction methods, block construction methods, and long block construction methods.

The panel construction method uses plates for condenser construction at the manufacturing factory.
This is a construction method in which pipe materials, shaped steel materials, etc. are processed into predetermined shapes, and then the plates, pipe materials, and shaped steel materials are sent as they are and welded and assembled on site. The major problem is that the on-site assembly and installation period will be longer.

The block construction method is a construction method in which the condenser is divided into several blocks at the manufacturing factory and then transported to the site and assembled. Since the blocks are constructed in separate sections, highly specialized techniques are required for on-site welding and assembly work. Furthermore, since large blocks are assembled within the manufacturing industry, there is a problem in that it prevents effective use of the area within the factory building and obstructs traffic within the factory.

In the long block construction method, the condenser is divided as appropriate in the height direction, and the condensers are divided along a plane perpendicular to the vertical division. This has the advantage that on-site welding assembly does not require highly specialized technology and the construction period is short, but since the long block-shaped condenser is assembled within the manufacturing factory, the area inside the factory building can be used effectively. It has the same problems as the block construction method in that it obstructs traffic within the factory. Moreover, since long blocks are assembled and transported,
Special consideration and skill are required for loading onto a transport vehicle, unloading from a transport vehicle, and transporting the product into the installation building. In other words, since long blocks are assembled and transported, if the cargo is handled carelessly without taking precautions such as placing it on a highly rigid pallet-like member or providing multiple lifting supports, the long blocks may be assembled and transported. There is a risk that excessive bending stress will be generated in the condenser assembled.

The present invention has been made in view of the above-mentioned circumstances, and when carrying out separate transportation and assembly of large condensers using the long block construction method, there is no need to make effective use of the area of the factory building, and there is no risk of interfering with traffic within the factory. Furthermore, there is no risk of excessive bending stress occurring during transportation of the condenser in a divided state, and the condenser can be safely and easily loaded onto a transportation vehicle and transported to the installation building. It is an object of the present invention to provide an installation method and a structure of a condenser suitable for implementing the above method.

In order to achieve the above object, the method according to the present invention sets the divided shape of the condenser in accordance with the divided transportation plan of the condenser, and selects the parts of the divided condenser at the installation site. A plurality of surface plates, which serve as base members of the condenser, are constructed for each divided part including the part in contact with the foundation, and when the divided condensers are assembled into one condenser, the above-mentioned A connecting member that determines the relative position of a plurality of surface plates is configured to be removable, and a rolling member is provided on the surface plate for supporting and transferring the load of the condenser divided parts assembled on the surface plate. and connecting the plurality of surface plates with the connecting member,
The condenser is assembled and fixed in a divided shape on top of it, the assembled condenser is divided according to the transportation plan, the aforementioned connecting member is removed, the divided condenser is pushed up together with the surface plate, and the aforementioned condenser is moved up. After being loaded onto a transport vehicle using rolling members, and unloaded after being escorted to a location near the condenser installation site,
The method is characterized in that the split-shaped condenser is integrally assembled and installed by being transferred onto the installation foundation by the rolling member, and by connecting a plurality of surface plates to each other by a connecting member.

In addition, the structure of the present invention includes a plurality of surface plates configured according to the divided shape of the condenser, and a plurality of surface plates described above, in order to safely and easily implement the above method and exhibit its effects. It is characterized by having a rolling member for transportation built into each of the plates, and a removable rolling member for coupling the plurality of surface plates to each other.

When a condenser is divided into an upper shell, a connecting shell, a shell body, a condensate reservoir, etc., the shell body is the largest in terms of weight and dimensions and is difficult to transport. This is a member that is installed on the foundation. Fig. 1 shows two long blocks obtained by vertically dividing the above-mentioned trunk body into vertical sections, and Fig. 2 shows the above-mentioned two long blocks assembled in an installed state.

For convenience of explanation, the two divided condenser body bodies are named long block 1 and long block 2, respectively.

A surface plate 3 for assembling the long blocks 1 and 2 described above is shown by a phantom line 3 in FIG. and the third
The figure shows a perspective view of one embodiment of the above-mentioned surface plate 3.

Two surface plates 3 are formed in order to place and assemble the long blocks 1 and 2 respectively. Third
The two surface plates 3 shown in the figure are shown in solid lines in relative positions when the long blocks 1 and 2 are assembled as shown in FIG.

Each surface plate 3 is formed into a frame shape by combining two vertical members 3a and five horizontal members 3b. Then, two surface plates 3 are arranged in a predetermined manner, and five connecting members 3c are spanned between them and detachably attached.

A large number of rolling members 4 are attached at regular intervals to the lower surface of the vertical member 3a of the surface plate. FIG. 3 shows the mounting position with imaginary lines, and FIG. 4 shows a partially cutaway perspective view. The rolling member in this embodiment includes 15 rollers 4b in a retainer 4a as shown in FIG.
It is constructed so that heavy objects can be transported while being circulated endlessly, and is fixed to the lower surface side of the vertical member 3a of the surface plate.

FIG. 5 shows an example of a work process for assembling a condenser in a divided state.

Choose as firm and horizontal ground as possible to set up a work area for assembly line work. This figure shows the process of arranging two long blocks 1 and 2 and assembling them separately as shown in Figure 2. A is the preparation stage, B is the middle stage of assembly, and C is the completion stage. However, it depicts the meaning of completion as a long block.

As shown in Figure A, two assembly plates 3 are placed, and five connecting members 3c are attached to temporarily connect them.

The body of the condenser is assembled vertically on the above-mentioned assembly plate 3 and on top of the assembly plate 3, respectively. For assembly, the components are not only placed on the surface plate 3, but also permanently fixed using means such as welding, bolts and nuts, etc.

As the assembly of the long block progresses, the surface plate 3 is sequentially moved to the right in the figure. At this time, it can be easily transferred by the rolling member 4 shown in FIG.

This figure B shows a state in which the side plate 6 of the trunk body has been assembled and the tube support plate 7 is suspended and fixed therein, and this figure C shows a state in which the thin tube 8 is inserted into the tube support plate 7 and the tube is nested. 9 is shown. After assembling the two long blocks 1 and 2 in this workshop, the connecting member 3c of the surface plate is removed and the two assembly surfaces 3 are separated. As a result, long blocks 1 and 2 can be transported separately.

After the long block is assembled on the surface plate 3 in the manner described above, it is moved further to the right from position C and moved onto the lift device.

FIG. 6A shows the long block 1 transferred onto the lift device 10 as described above on the surface plate 3 for assembly.
This shows the state in which they are pushed up together while remaining fixed.

After pushing up the long block in this way, as shown in Figure B, the transportation vehicle 11 is driven backwards as shown by arrow D, and the four lift cylinders 10a to 10d of the lift device 10 are lowered one after another to lift the long block. 1 onto the loading platform of the transportation vehicle 11.
In this case as well, since the rolling member is attached to the lower surface of the surface plate 3, it is possible to easily load the products. Figure C shows a state in which the long block 1 has been loaded onto the loading platform of the transportation vehicle 11. Loading of the long block 2 is also carried out in the same manner as above.

Figure 7 shows the work site where the condenser will be installed.
2 is a building, 13 is a turbine frame, and 14 is a building foundation. The imaginary line E indicates the temporary location of the long block outside the building, and the imaginary line H indicates the installation position of the condenser.

A retractable pedestal 15 is temporarily installed on the building foundation 14, and the long block 1 is pulled into the retractable pedestal 1 together with a surface plate 3 for assembly using a crane device 16 (only the hanging equipment is shown).
5. Hang it to the lower position above.

At this time, since the highly rigid surface plate 3 is fixed to the lower surface of the long block 1, there is no risk of applying excessive bending stress to the long block 1 even if no special consideration is given to slinging. Therefore, crane work at the installation site can be carried out cheaply and easily.

The long block 1 is carried from position F on the retractable stand 15 to the condenser installation position H as indicated by arrow G. At this time, since the surface plate 3 is fixed to the bottom surface of the long block 1, the retractable frame 1 which is a temporary structure
Even if the upper surface of the long block 5 is not strictly flat and is slightly bent, there is no risk of excessive bending stress being generated in the long block 1. Moreover, since this carrying-in operation can be carried out using the rolling member attached to the surface plate 3, carrying-in can be carried out quickly and easily.

As above, create two long blocks 1 and 2.
is carried to the condenser installation position H, and the two surface plates 3,
When the above-mentioned connecting member 3c (not shown) is attached to the long blocks 3 and connected, both surface plates are aligned in the correct relational position, and therefore the two long blocks 1,
2 come into contact with each other in the correct posture. Therefore, the welding assembly of the condenser in the existing pond can be performed easily, inexpensively, and with high precision. The surface plate 3 used for delivery was buried while still attached to the condenser, and will be used permanently as a foundation member.

As explained above, the method for transporting, assembling and installing a condenser in parts according to the present invention forms a surface plate for assembling the condenser in accordance with the divided shape of the condenser, and
A rolling member for transfer is incorporated into the lower surface of this surface plate for assembly, and while the surface plate is moved within the assembly factory, the condenser is assembled in a divided shape above it, and the condenser in the divided shape is assembled. Push up together with the assembly surface plate, load it onto a transportation vehicle using the above-mentioned transfer means, unload it near the condenser installation location, and then move it to the installation location using the above-mentioned transfer means and install it. Therefore, when transporting and assembling large condensers in parts using the long block construction method, there is no need to make effective use of the factory building area or obstruct traffic within the factory, and it is possible to transport the condensers in a divided state. There is no risk of generating excessive bending stress, and the product can be safely and easily loaded onto a transport vehicle and transported to the installation building. Furthermore, the method of the present invention described above can be applied to the divisional transportation and assembly of large condensers using the block construction method to obtain similar effects.
