Description

Specification

Technical Field of the Invention The hanging balance for 'product group setting', the components of the hanging balance, and the method of constructing the plant using the hanging balance

The present invention relates to a hanging balance used for constructing a plant and a method of using the same. Background art

When constructing a plant, it is necessary to suspend each product such as the equipment that composes the plant with a crane, carry it into the plant building under construction, and install it. As a method of lifting points used when lifting heavy products, there is a known method in which a hanging repiece is attached to the product body in advance, and a wire hung with a crane is hung on that part. Yes (conventional method 1). Also, as a method of setting the detachable hanging point, make it possible to set the eyebolt on the product, and when lifting the product, hang the wire suspended by the crane on the eyebolt with the eyebolt set on the product body. Thus, a method of lifting is known (conventional method 2). It is also known to use a lifting balance as a means to ensure stability (horizontal) when lifting products. In this case, the product can be lifted by hanging a wire between the suspension point set on the product body and the suspension point provided on the suspension balance, and lifting the suspension balance in such a state from the crane.

In addition, multiple products are combined (modulated) via a steel frame structure so that the positional relationship between the products is maintained in the same way as the final setting state. Know how to hang it in the crane However, as the size of the module increases, the amount of steel frames used in the steel frame structure to maintain the positional relationship between products increases.

In addition, when a module is constructed by combining each product, the center of gravity of the module to be lifted changes depending on the combination of each product or each product to be combined changes. It is necessary to change the hanging point.

A technique described in Japanese Utility Model Laid-Open No. 5-20773 is known as a method for accurately transporting products such as construction materials to a predetermined installation position of a building without being affected by external factors such as wind. In this method, the product is supported on a hanging balance with legs that can travel on the floor of the building via a two-dimensional horizontal driving device and a vertical driving device, and a plurality of hanging brackets attached to the hanging balance. Hang the wire supported by the lane, lift the product together with the suspended balance in the crane, hang it on the floor of the building, support the legs of the suspended balance on the floor, and then move the suspended ceiling horizontally to reach the product installation position. Thereafter, the product is positioned at the installation position of the product by a horizontal two-dimensional drive, and then the product is lowered by the upward and downward drive to drop the product to the installation position. In such a conventional technique, since the lifting is performed in units of one product, it is not possible to cope with the work of lifting a plurality of products required for accelerating the construction of a plant as a group. Also, when multiple products are lifted as a module to enable this, the center of gravity of the module is difficult to predict, the lifting posture becomes unstable, and the relative positional relationship between the products is disrupted. Cheap. Disclosure of the invention

A first object of the present invention is to integrate a plurality of products without breaking the relative positional relationship as much as possible. The purpose of the present invention is to provide a suspending balance suitable for being suspended on a universe and collectively suspending it.The second purpose is to provide components suitable for constructing the suspending balance. Another object of the present invention is to provide a method for constructing a plant using the hanging balance.

The first object is to provide a first balance which can be freely supported by a universe of stars, a plurality of suspension fittings mounted on the first balance, and a group of products which are supported by the first balance to be vertically movable.

And a plurality of hanging pieces dispersed and attached to the second balance at least in the two-dimensional horizontal direction.

That is, the wire supported by the crane is hung on the hanging bracket, the first balance is suspended, the second balance is suspended from the first balance, and a plurality of products are suspended from a plurality of positions of the second balance. Since multiple products are hung in a two-dimensional horizontal direction, they can maintain the relative positions of multiple products without collapsing.In addition, the center of gravity of the entire product group is unexpectedly shifted. Even though the suspension points are dispersed, the effect of suppressing the instability of the suspension posture of the product group due to the change in the center of gravity can be obtained, and multiple products can be bundled together while maintaining the preset relative positional relationship as much as possible. The first balance suspended in the building at the set position of the product group with a crane is supported by the star and is in a more stable state than that supported by the crane. After the product group is in a stable support state And lowering the second balance for work can be obtained to put a product group the set position, collectively a plurality of product without losing the setting positions of a plurality of products Can be quickly suspended at the set position, which contributes to shortening the plant construction period.

The second object is to provide a hanging balance frame including a plurality of legs, a beam connected to the plurality of legs by bolts, a plurality of hanging hardware provided on the frame, and the frame. A horizontal frame constituting a free-standing hanging balance frame or a hanging balance provided with a brace attached by another bolt and crossed obliquely in the vicinity of the joint between the leg and the beam in the plane including Slide means comprising a pair of hold plates sandwiching the arm from both sides, fastening means provided between the pair of hold plates, and a suspension piece attached to the slide means. It can be achieved by hanging metal fittings.

That is, according to the self-standing hanging balance frame of the present invention, it corresponds to the frame of the first balance in the invention for achieving the first object, and the frame is self-standing with a plurality of legs and is self-standing. As a result, the strength of the frame is reinforced by the brace so that it can withstand the load applied to the frame, the stabilizing effect of the frame is obtained, and the first object of the invention for achieving the first object of hanging a plurality of products together is The effect of being applicable to the frame of the balance is obtained. According to the hanging bracket of the present invention, the clamping state of the horizontal frame constituting the hanging balance by the pair of hold plates is released by loosening the fastening means. The sliding means is continuously slid along the frame and positioned at the position necessary to stabilize the suspended load posture in relation to the center of gravity of the suspended load. After that, by tightening the tightening means, the holding state of the pair of hold plates against the horizontal frame constituting the hanging balance is reproduced, and the hanging posture of the hanging balance and the suspended load is stabilized to a desired posture. Is obtained, and by its operation, multiple products can be suspended The lifting metal according to the invention for achieving the first object has the effect of being able to cope with a change in the center of gravity of the entire product group due to a change in the product or a change in the arrangement of the product when the product is raised. invented for achieving the suitable and is _t third purpose is the one product group in a state disposed in the mutual positional relationship or similar positional relationship to the set position in the set position the positions of a plurality of products A plurality of portions of the second balance from the first balance are vertically movably supported, and a plurality of portions of the module are suspended from a plurality of portions of the second balance dispersed in the two-dimensional horizontal direction. While maintaining the mutual positional relationship, the module is lifted by suspending the first balance with a crane, carried into a building above an installation position, and the first balance is loaded into the building. Les Then, a hanging balance was used in which the module was moved to the module installation position by lowering a plurality of locations of the second balance, and the product group was installed in the installation position. This is the method of plant construction.

According to this construction method, a plurality of products can be collectively carried as a group of modules to the installation position of the products in the building, and at that time, the modules are suspended at hanging point positions dispersed horizontally and two-dimensionally. Therefore, the relative setting position of each product is less likely to collapse, and the overall module is less likely to tilt in the vertical direction due to the center of gravity of the module. And the module is lowered to the installation position, so that the effect of further facilitating the installation and cleaning is obtained, and the effect of shortening the construction period of the plant is obtained.

Various single products such as large equipment 1, piping 2, valves 3, operation base 4, and sabot 5 constituting the plant are arranged in advance in the positional relationship where those products are installed, that is, the set positional relationship. .

The individual products are linked together so that the relative positions of the individual products in the set positional relationship do not collapse.

In this way, a plurality of products are set as a group of products as a module A. The hanging balance for hanging the module A has the following configuration.

That is, the suspension balance is roughly composed of a combination of the first balance 12 and the second balance 11.

The first balance 12 has four steel columns as legs 32, as shown in FIGS.

Each leg 32 is connected to four surrounding surfaces by an upper beam 33 made of steel and a lower beam 34 as well.

As shown in Fig. 3, each connecting part is a stop welded to the leg 32 so that the leg 32 and each upper f-beam 33, 34 can be disassembled. The bracket 36 is connected to the upper beam and the lower beam by the fastening means using the bolt 'nut 41'.

As described above, the frame of the first balance 12 is configured by connecting the four legs 32 and the eight beams 33, 34 in total by the fastening means.

At the corner where the leg 32 and each beam 33, 3 intersect, a bracket 80 welded and fixed to the leg 32 is provided as shown in Fig. 3, for example.

Each bracket 80 facing each other diagonally, as shown in Fig. 2, The head 8 1 is connected to the brace 35 by a turnbuckle 82 to provide tension by rotating the turnbuckle 82 to the mouth 81, and the first is composed of a leg 32 and beams 33, 34. The frame of the balance 12 is reinforced so that it does not collapse.

The rod 81 of the brace 35 is detachably connected to the bracket 80 by fastening means using bolts 54 as shown in FIG.

If the module A appears to protrude from side to side as shown in Fig. 1, the side of the first balance 12 will have a brass surface as shown in Fig. 15 (c). No adoption will be made, and the corner fitting 83 will be fastened to the upper and lower beams 33, 34 and the leg 32 by fastening means using bolts and nuts to reinforce it.

When the corner bracket 83 is adopted, the fastener is not used at the place where the corner bracket 83 is adopted, and the leg 32 and each of the upper and lower beams 33, 3 are fastened by the corner bracket 83 and the bolts and nuts. Also has the function of connection with 4.

The reason why the rod 81 and the turnbuckle 82 are not used as the braces 35 and the oblique beams made of steel are not used is to reduce the weight of the hanging balance and to facilitate removal of the hanging balance.

As described above, the frame of the first balance 12 is provided with the plurality of legs 32 connected by the upper and lower beams 33, 34, and is reinforced, so that the module A is free standing with the module A suspended. It has a self-supporting frame that can be used.

As shown in Fig. 2 and Fig. 15, the upper beam 33 of the first balance 1 2 is equipped with eight hanging brackets 31 each of two on the beam 33.

Each hanging bracket 31 includes a sliding means and a hanging piece 51.

As shown in Figs. 4 and 5, the sliding means is composed of two hold plates 52 sandwiching the upper beam 33, and an upper beam between the two hold plates 52. It comprises a double-screw bolt 53 provided two by two above and below 33, and a fastening means composed of each nut 54 screwed to the double-screw bolt 53.

By loosening the fastening means, the friction between the hold plate 52 and the upper beam 33 is reduced and the upper beam 33 can be slid, and the hold plate 52 is tightened by the fastening means. It can be fixed to the upper beam 33 by crimping so as not to slide.

In this slide means, the flange portion of the suspension piece 51 is sandwiched between the upper beam 33 and the two screw bolts 53.

The second balance 11 is combined with the first balance 12 as described above to form a hanging balance. The combination and the configuration of the second balance 11 are as follows.

As shown in FIG. 15, the second balance 11 has a frame in which five steel beams 91 in a horizontal plane are connected and fixed in the shape of a star. As shown in FIG. 15, a plurality of suspension re-pieces 84 are fixed to the lower surface of the frame, and the suspension pieces 84 are dispersed and arranged in the horizontal two-dimensional direction.

Such a second balance 11 is composed of four chain blocks suspended from four suspension pieces 8 5 attached to the upper beam of the first balance 1 2.

It is suspended and supported by 4 2 and combined with the first balance 12.

Specifically, a wire 86, which can be unwound from four chain blocks 42, is wound around a hanging piece 87 attached to the upper surface of the frame of the second balance 111, and the second balance 111 is suspended. To support.

For this reason, when the four chain blocks 4 2 are operated and the wire 86 is paid out, the second balance 11 is lowered, and the four chain blocks 4 2 are obtained. The second balance 11 rises when the wire 18 6 is wound up by operating the wire.

As described above, the four chain blocks 42 are employed as a vertical drive device employed between the second balance 11 and the first balance 12. In addition, if the amount of winding or unreeling of the wire from the four chain blocks 42 is made different from each other, the vertical balance posture of the second balance i 1 is changed and the load is lifted. The module A can be controlled from the horizontal position to the inclined position or from the inclined position to the horizontal position in consideration of the relative relationship between the setting surface and the suspended load when the suspended load arrives at the setting surface.

Such a suspended balance is used as follows.

The purpose of use is described below by taking the construction of a nuclear power plant as an example.

Various single products such as large equipment 1, pipes 2, valves 3, operation frames 4, and supports 5 that make up a nuclear power plant are pre-arranged in the set positional relationship where they are finally installed .

Attach hanging points, such as hanging pieces, to key points of each product.

Further, as shown in FIG. 9, a cylindrical sleeve member 72 is temporarily fixed to the lower part of the leg 71 of the operation base 4 by spot welding or the like.

On the other hand, a hanging balance in which the second balance 11 is combined with the first balance 12 is prepared, and each chain block 8 8 is hung on each hanging piece 8 4 of the second balance 11 1 to prepare the first balance. Let the balance 1 2 stand alone.

The wire 89 pulled out from each chain block 88 is hung over each hanging piece attached to each product.

In some cases, wire 89 is wrapped around the product comprising module A.

After that, scan each chain block 8 8 for each wire 8 9 Consideration should be given so that the relative positions of the products that make up module A do not significantly deviate from the set positions.

In addition, when considering the relative positional relationship between the products that make up module A so that they do not significantly deviate from the set position, if necessary, use a structure to connect those products to each other to prevent collapse. I do.

In this way, a plurality of products can be grouped into a group of products as module A, and module A can be attached to a hanging balance in an easy-to-work place such as an assembly yard in a factory or a nuclear power plant construction site. Do with.

Thereafter, the container is transported to a position where it can be lifted by the crane 90 installed adjacent to the building 92 in the middle of the construction of the nuclear power plant.

If it is in a position where it can be lifted by the crane 90 without being transported, the transport is omitted.

After that, taking into account the center of gravity of the module A as a whole, the hanging bracket 31 is changed by sliding along the upper beam 33 to change the position of the hanging bracket 31 when the module A is suspended. Adjust the position so that A does not tilt, and fix it again at the adjustment position.

The wire 93 supported by the crane 90 is wrapped around the eight hanging brackets 31 of the first balance 12 to support a load of the crane 90 so that the lifting balance does not float.

In this state, by scanning each chain block 42 and winding the wire 86, the second balance 11 is lifted, and the module A is lifted and floated.

In this case, even if an operator may work under the hanging balance, the crane 90 supports the hanging balance to some extent, in which case the safety is low. We can secure enough.

Thereafter, the module A is lifted and suspended by the crane 90, and the ceiling function is still open by the swivel function of the crane 90. Bring like.

After that, it is suspended from the building 92 where the module A is set.

After the suspension, as shown in Fig. 1, the legs 32 of the first balance 12 arrive at the floor of the building 92 and become independent.

In this state, module A is suspended by the suspension balance. The floor 21 of the building 92 is provided with a foundation 61 and an embedded metal 22 before being suspended.

If the crane 90 is to be engaged in the next work sooner, remove the wire 93 from the hanging bracket 31 of the first balance 12 and remove the first balance 12 as shown in FIG. Be independent and supported by the floor 2 1 of the building 9 2.

Therefore, the legs 3 2 of the first balance 12 are used as support means from the building 92.

If it is not necessary for crane 90 to be engaged in the next task quickly, force to bear load on crane 90 to the extent that first balance 12 does not float, and wire 9 3 not to bear load Is secured between the crane 90 and the hanging bracket 31 to ensure safety more than enough.

Next, by operating the chain block 4 2 and paying out the wire 86, the second balance 11 is lowered, and the product constituting the module A is laid on the base 6 1 ゃ.

From the start of suspension of module A to suspension of module A, module A is supported from the same dispersed position in the two-dimensionally dispersed locations on the plane. The relative positions of the products that make up module A are suppressed from collapsing, and the amount of connection structures used to suppress the collapsing can be reduced, and the lifting load is reduced accordingly. Many products can be suspended as module A.

If the entire module A is vertically inclined when the module A is suspended, the winding or unwinding amount of the wire 86 from each chain block 42 is changed relatively to the initial state. Control the posture to the set posture of.

If the relative positional relationship between the products that make up module A is broken, just before the module A is suspended and unrolled, winding or unwinding of the wire 89 from each chain block 88 will be performed. The position is corrected to the initial set position by relatively changing the amount.

After correcting these positions and postures, install the product 1 completely on the foundation 61 by placing each product on the set position.

When the position and posture of the tip are not correct, or the accuracy of the floor of the building is inaccurate, or the position of the legs 3 2 of the operation base 4 is suspended in the air due to the position adjustment in the building 9 2 Is to suspend the operation base 4 by the chain block 88 and release the temporary fixing of the sleeve member 72 temporarily fixed to the leg 71 as shown in FIG. Then, the lower end of the sleeve member # 2 is attached to the embedded metal piece 22 by sliding downward.

After that, as shown in Fig. 11, the upper end of the sleeve member 72 and the leg 71 are connected and the lower end of the sleeve member 72 and the embedded metal member 22 are connected and fixed by main welding. It is installed on the floor 21 of the building 92 as shown in FIG.

The wire 86 from the chain block 88 is detached from the hanging point of each product to separate each product constituting module A from the hanging balance. After the installation of each product of module A, loosen the turnbuckle 82 of the brace 35 and then the brace 35 of the first balance 12 and the leg 32, and the leg 32 and the upper and lower beams 3 Loosen the bolts and nuts 41 and 54, which are the means for fastening to the pieces 3 and 34, and remove the corner fitting 83 to disassemble the first balance 12.

During the installation and disassembly work, if the construction of the building 92 progresses and the ceiling at the installation site is completed or is under construction, the disassembled first ceiling 12 components will pass through the building 92. Transported to the outside for reassembly and reuse. If the second balance 11 is also assembled using a bolt / nut, it is similarly disassembled, carried out, and reassembled and reused.

If an assembly method that cannot be easily disassembled is used, separate and transport.

If there is no ceiling at the installation location, only the lower beam 3 4 that interferes with the module A when lifting the lifting balance is removed from the leg 32, and the first and second balances 1 1 1 and 2 are lifted together and carried out of the building. The first balance 1 2 is reused together with the second balance with the lower beam 3 4 attached to the legs 32.

The situation after removing the suspended balance out of the building 92 and removing it is as shown in Fig. 13.

In another embodiment of the present invention, as shown in FIG. 14, the present invention can be applied to a case where both side walls 23 of a building 92 are completely completed in strength.

A receiving member 24 is fixed to a location higher than the module A on the side walls 23 facing each other of the building 92 using an anchor bolt or the like.

On the other hand, the first balance 1 2 can place the upper beam 3 3 on the two receiving members 24 at the same time instead of the legs 3 2 as support means for the building 9 2 as compared with the previous example. Extended to the position.

The extension is used as support for the building 92.

Since there are no legs 32 as in the previous example, there is no lower beam 34 in this example, so the weight is reduced, so that many products can be suspended as one module A.

Others are the same as the previous example.

The construction method of the nuclear power plant is similar to the previous example, and the differences are as follows.

In other words, each product such as each device 1 constituting the nuclear power plant is similar to the previous example, and the different points are as follows.

That is, each product such as each device 1 constituting the nuclear power plant is made into a module A as before, and is suspended by a hanging balance composed of the first balance 12 and the second balance 11 as before. The balance is suspended at the crane 90 and suspended between the side walls 23 of the building 92.

While being suspended, both ends of the upper beam 33 of the first balance 12 are received by the receiving member 24 and supported by the building 92.

This situation is shown in Figure 14, where module A is still floating.

After that, remove the module A as in the previous example and install the products that make up the module A.

After the installation is completed, the first balance 12 and the second balance 11 are cleaned 9 with the connection between the second balance 11 and the products constituting the module A being disconnected. Lift it at 0 and remove it outside the building 9 2 for reuse.

In this removal, the first balance 12 does not have the lower beam 32 that interferes with the module A at the time of lifting, so that the frame of the hanging balance does not require any disassembly work, and the removal work is speeded up. If the ceiling is made due to the progress of the construction of the building 92, the first balance 12 'and the second balance 11 are divided and removed through the building to the outside of the building.

Other details are the same as in the previous example in the construction method.

In any of the embodiments, the present invention can be universally applied to the installation of a product group having various center-of-gravity positions. This has the effect of reducing the amount of material of the main frame structure (structure) that was required for the construction.

According to the method of constructing a plant using a hanging balance according to the embodiment of the present invention, the product between the products constituting the module is reduced despite the fact that the amount of the main frame structure (structure) member is reduced. The relative positional relationship does not collapse, the installation can be performed quickly, and the construction period can be shortened.
