Description

Suspension balance for setting the product range, components of the suspension balance and construction method of the plant using the suspension balance

When constructing a plant, it is necessary to lift each product, such as the apparatus which comprises a plant, with a crane and to carry it in the plant building under construction, and to install.

As a method of the suspension point used when lifting a large weight product, the method of attaching a suspension piece to the product main body beforehand and hooking up the wire suspended by a crane to the part is known (a conventional method 1). In addition, as a setting method of the detachable suspension point, the eye bolt can be set on the product, and when lifting the product, a method of lifting the wire suspended from the crane by the crane with the eye bolt set on the main body of the product is lifted. It is known (prior method 2). Moreover, the method of using suspension balance is known as a means for ensuring the stability (horizontal) degree at the time of lifting a product. In this case, the product is lifted by hooking the wires to the suspension point set on the product body and the suspension point set on the suspension balance, and hanging the suspension balance in such a state with a crane.

In addition, there is also known a method in which a plurality of products are combined (modulated) into a crane in a plant building as a unit so that the positional relationship between the plurality of products is held in the same state as the final setting state. The larger the module, the greater the amount of steel used in the forced installation structure to hold the positional relationship of each product.

In addition, when composing modules by combining each product, the center of the lifted module changes according to the combination method of each product or by changing each product to be combined, and the necessity of changing the suspension point based on the change occurs. .

As a method of bringing products such as construction materials and the like into a predetermined installation position of a building with high accuracy without being influenced by external factors such as wind, a technique disclosed in JP-A-5-20773 is known. This is a wire supported by a crane to a plurality of suspension anvils attached to the suspension balance by means of a suspension device with a bridge that can travel the floor of the building, through a drive device in the horizontal two-dimensional direction and a drive device in the vertical direction. Lift the product by the crane for each suspension balance to support the bridge of suspension balance on the loading board of the building, and then run the suspension balance flat to reach the installation location of the product, and then install the product by the horizontal two-dimensional driving device. The product is placed in the position, and then the product is lowered by the up and down driving device to lower the product at the installation position. In such a prior art, since it lifts by one product unit, it cannot cope with the operation of carrying out collectively lifting the several product requested | required in order to accelerate the construction of a plant as a group. In order to enable such a response, when lifting a plurality of products as a module, it is difficult to predict the center position of the module, the posture becomes unstable, and the relative positional relationship of each product is easily shifted.

The present invention relates to a suspension balance used in the construction of a plant and a method of using the same.

Is achieved by.

That is, the wire supported from the crane is suspended over the suspension anvil, the first balance is suspended, the second balance is suspended from the first balance, the plurality of products are suspended from the plurality of places of the second balance, and suspended in the horizontal two-dimensional direction. As the points are distributed and suspended in a plurality of products, the function of maintaining the relative positions of the plurality of products can be maintained without shifting them, and the suspension points are dispersed even if the center of the whole product is unexpectedly shifted. Instability can be suppressed. In addition, a plurality of products can be brought into the building by crane at the set position of the product group while maintaining the relative positional relationship set in advance, and the first balance brought into the building is supported by the building and is more stable than the crane. In the stable state, the support state of the product line is stabilized, and then the second balance is lowered to obtain the action of positioning the product line at the set position, and the plurality of products are collectively placed without shifting the set position of the plurality of products. Therefore, it is possible to obtain the effect that can be brought into the set position quickly, contributing to shortening the construction period of the plant construction.

The second object is a frame of a suspension balance consisting of a plurality of legs and beams bolted to the plurality of legs, a plurality of suspension anvils mounted on the frame, an inner surface that includes the frame, and the leg portion; Between a pair of holding plates and a pair of holding plates which sandwich a horizontal frame constituting the suspension balance from both sides, or a self-supporting suspension balance frame having a brace attached to the beam by another bolt and placed obliquely near the connection portion of the beam. It can achieve with the suspension anvil provided with the slide means which consists of the fastening means equipped with the suspension means, and the suspension piece attached to the said slide means.

That is, according to the self-supporting suspension 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 provided with a plurality of legs, and the load applied to the frame by self-supporting. The strength of the frame is reinforced by the brace so that it can withstand the stability of the frame, and can be applied to the frame of the first balance in the invention for achieving the first object of lifting up a plurality of products collectively. According to the suspension anvil of the present invention, by loosening the fastening means, the clamping state of the horizontal frame constituting the suspension balance by the pair of holding plates is released, and the slide means is continuously moved along the frame. Slide to the position necessary to stabilize the attitude of the suspension cargo in relation to the center of the suspension cargo. And then tighten the fastening means to reproduce the clamping state of the horizontal frame constituting the suspension balance by the pair of holding plates, thereby obtaining the effect of stabilizing the suspension balance and the suspension posture of the suspension cargo in a desired posture. It is possible to obtain an effect that can cope with a change in the overall center of the product line when the product is deformed or the arrangement of the product is changed when the plurality of products are collectively lifted by the action. It is very suitable as a suspension anvil in the invention for achieving this.

In order to achieve the third object, the invention provides a module in a state in which the positions of a plurality of products are arranged in a mutual positional relationship at a setting position or in a positional relationship close to the setting position as one module, and the second balance from the first balance. The first balance is suspended by a crane while the plurality of places of the balance are supported so as to be movable upward and downward, and the plurality of places of the module are suspended from the plurality of places distributed in the horizontal two-dimensional direction of the second balance, maintaining the mutual positional relationship.

The construction method of the plant using the suspension balance to install the product line in the installation position .

According to this construction method, a plurality of products can be collectively brought to the installation position of the product as a group of modules, and at that time, the modules are suspended at the suspension point position distributed in the horizontal two-dimensional direction. It is easy to install because there is little misalignment of the setting position and the inclination of the whole up and down direction along the center of the module is not easily generated, and the module is lowered to the installation position by supporting the suspension balance in the building. This promoted action can be obtained, and the effect of shortening the construction work period of the plant can be obtained by the action.

The products of various units such as the large apparatus 1, the pipe 2, the valve 3, the operating stand 4, the support 5, etc. constituting the plant have a positional relationship where they are installed, that is, a set positional relationship. Is pre-arranged.

The products of various groups are connected so that the relative positions of the products of various groups in the set position relationship are not shifted.

In this way, a plurality of products are used as the module A to form a group of products.

Suspension balance for lifting this module A is provided with the following structures.

That is, the suspension balance is largely divided into a combination of the first balance 12 and the second balance 11.

The first balance 12 has four steel support pillars as the legs 32 as shown in Figs.

Each leg 32 is connected to all four sides by the upper beam 33 and the lower beam 34 made of steel.

The connecting means bolts the fixing anvil 36 welded to the leg 32, as shown in FIG. 3, so that the leg 32 and the upper and lower beams 33 and 34 are resolvable. And a fastening means by the nut 41 to the upper beam and the lower beam.

In this way, the frame of the first balance 12 is configured by connecting four legs 32 and eight beams 33 and 34 in total up and down with a fastening means.

At the corners where the legs 32 and the beams 33 and 34 intersect, a bracket 80 welded and fixed to the legs 32 is provided, for example, as shown in FIG.

Each bracket 80 facing diagonally is connected by the brace 35 by the rod 81 and the turnbuckle 82 as shown in FIG. 2, and gives tension to the rod 81 by rotating the turnbuckle 82. Thus, the frame of the first balance 12 composed of the legs 32 and the beams 33 and 34 is reinforced so as not to be displaced.

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

In the case where the module A is protruded from side to side as shown in Fig. 1, as shown in Fig. 15C, the brace 35 is not employed on the side of the first balance 12, and the corner is Reinforcement is performed by fastening the anvil 83 to the upper and lower beams 33 and 34 and the legs 32 by means of fastening by bolts and nuts.

In the case where the corner anvil 83 is adopted, the fixed anvil is not adopted to the place of employment, but the legs 32 and the upper and lower beams 33 and 34 are fastened by the corner anvil 83 and the bolts and nuts. ) Also achieves the connection function.

The reason why the rod 81 and the turnbuckle 82 are used as the brace 35 and the inclined beam made of steel is not used is to reduce the weight of the suspension balance and facilitate the removal of the suspension balance.

In this way, the frame of the first balance 12 has a plurality of legs 32 connected to each of the upper and lower beams 33 and 34, and the reinforcement is performed so that the frame of the first balance 12 can stand in the suspended state of the module A. It consists of a frame.

The upper beam 33 of the first balance 12 is provided with a total of eight suspension anvils 31 in one beam 33 as shown in FIGS. 2 and 15.

Each suspension anvil 31 is composed of a slide means and a suspension piece 51.

As shown in Figs. 4 and 5, the slide means is provided with two holding plates 52 for holding the upper beam 33 and two upper and lower portions of the upper beam 33 between the two holding plates 52. It consists of the fastening means which consists of the both-threaded bolt 53 and each nut 54 screwed to the both-threaded bolt 53. As shown in FIG.

The slider means can loosen the fastening means, thereby reducing the friction between the holding plate 52 and the upper beam 33, thereby sliding the upper beam 33, and by tightening the fastening means, the holding plate 52 can be moved to the upper beam ( It can be fixed so as not to slide by pressing on 33).

In this slide means, the flange portion of the suspension piece 51 is inserted between the upper beam 33 and the both-thread bolt 53.

The second balance 11 is combined with the first balance 12 as described above to form a suspension 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 are connected and fixed in a blade shape in a horizontal plane.

As shown in Fig. 15, the plurality of suspension pieces 84 are fixed to the lower surface of the frame, so that the suspension pieces 84 are arranged in a horizontal two-dimensional direction.

The second balance 11 is suspended and supported by four chain blocks 42 suspended and attached to four suspension pieces 85 attached to the upper beam of the first balance 12. ) Is combined.

Specifically, the second balance 11 is suspended and supported over the suspension piece 87 in which the wire 86 which is released from the four chain blocks 42 and which can be wound is attached to the upper surface of the frame of the second balance 11.

To this end, when the four chain blocks 42 are actuated to release the wires 86, the second balance 11 is lowered. When the four chains blocks 42 are actuated to wind the wires 86, the second balance 11 is lowered. 11 rises.

In this way, the four chain blocks 42 are employed as the vertical movement driving device between the second balance 11 and the first balance 12.

In addition, if the amount of winding or discharging the wires from the four chain blocks 42 is different from each other, the inclination attitude of the second balance 11 in the vertical direction is changed, and the inclination attitude of the module A, which is the suspension cargo, is changed to the suspension cargo. In the case where it is located on the setting surface, the relative relationship between the setting surface and the suspended cargo can be controlled from the horizontal to the inclined posture or from the inclined to the horizontal posture.

Such suspension balance is used as follows.

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

The products of various groups such as the large apparatus 1, the piping 2, the valve 3, the operating stand 4, the support 5, etc. constituting the nuclear power plant are arranged in advance in the set position relationship at which they are finally installed. do.

Suspension points such as suspension pieces are attached to the elements of each product.

Moreover, the cylindrical sleeve member 72 is temporarily fixed to the lower part of the leg 71 of the operation mount 4 by spot welding etc. as shown in FIG.

On the other hand, the suspension balance which combined the 2nd balance 11 with the 1st balance 12 is prepared, and each chain block 88 is suspended on each suspension piece 84 of the 2nd balance 11, and the 1st balance Let (12) be independent.

The wire 89 released from each chain block 88 spans each suspension piece attached to each product.

In some cases, the wire 89 is wound around the product constituting the module A. FIG.

Thereafter, each chain block 88 is scanned to give an appropriate tension to each wire 89, so that the relative positional relationship of each product constituting the module A is considered so as not to deviate significantly from the set position.

And when considering that the relative positional relationship of each product which comprises the module A does not deviate largely from a setting position, if necessary, a structure is used to connect these products, and a deviation is prevented.

As described above, the case where a plurality of products are used as a module A and a group of products, and the attachment of the module A to the suspension balance are performed at a place where work is easy, such as an assembly plant in a factory or a nuclear power plant construction site.

Then, it carries to the position which can be lifted by the crane 90 installed adjacent to the building 92 which is during construction of a nuclear power plant.

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

Thereafter, the suspension anvil 31 is changed by sliding the suspension anvil 31 along the upper beam 33 in consideration of the overall center of the module A to raise the position of the suspension anvil 31 when the module A is lifted. Adjust the position so that it is not inclined and fix it again at the adjustment position.

The wire 93 supported by the crane 90 is supported by the crane 90 to some extent so that the suspension balance does not float over the eight suspension anvils 31 of the first balance 12.

In this state, each chain block 42 is scanned and the wire 86 is wound to lift the second balance 11 to suspend and float the module A.

At this time, even if a worker may work under the suspension balance, the suspension balance is supported by the crane 90 to some extent so that safety can be sufficiently secured.

Subsequently, the crane A is suspended and suspended for each suspension balance by the crane 90, and as shown in FIG. 7 above the building 92 of the nuclear power plant during construction in which the ceiling is still open by the turning function of the crane 90. Lift up

The descent then begins to descend into the location in the building 92 where the module A is set.

When the descent is completed, the legs 32 of the first balance 12 are located on the floor of the building 92 and stand free as shown in FIG.

In this state, the module A is suspended and suspended by the suspension balance.

The floor 21 of this building 92 is equipped with the foundation 61 and the buried anvil 22 before descent.

When the crane 90 is quickly engaged in the next work, the wire 93 is separated from the suspension anvil 31 of the first balance 12, and the first balance 12 is self-supporting as shown in FIG. ) To the bottom 21.

For this reason, the leg 32 of the first balance 12 is used as a supporting means from the building 92.

If the crane 90 does not need to be engaged quickly in the next work, the load is applied to the crane 90 to the extent that the first balance 12 is not injured or the wire 93 is not loaded. 90) and the suspension anvil 31 to secure enough safety.

Next, the second block 11 is lowered by operating the chain block 42 to release the wire 86 to lift the product constituting the module A into the base 61 and the buried anvil 22.

Since the module A supports the places distributed in the planar two-dimensional direction from the same distributed position from the start of the loading of the module A to the descent, the relative positions of the products constituting the module A are prevented from shifting. In order to suppress this, the quantity of the connection structure to be employed can be reduced, and the suspension load is reduced by that, and more products can be carried in as a package A.

When the module A is inclined in the vertical direction when the module A is lowered, the winding or release amount of the wire 86 from each chain block 42 is changed relatively, and the attitude is controlled by the initial setting posture. do.

In the case where the relative positional relationship of each product constituting the module A is shifted, the winding of the wire 89 or the amount of release of the wire 89 from each chain block 88 is changed relatively immediately before the end of the dropping of the module A. Correct the position to the initial setting position.

After correcting these positions and postures, the device 1 is completely supported on the base 61, or each product is placed in a set position and mounted.

The legs 32 of the operating stand 4 are lifted into the air by the position and posture of the front not corrected correctly or by the error of the precision of the building floor, or by the adjustment of the position within the building 92 of the operating stand 4. When floating, the operation mount 4 is suspended and supported by the chain block 88, and the sleeve member 72 temporarily fixed to the leg 71 is slid downward by releasing the temporary fixing as shown in FIG. The bottom end of the sleeve member 72 is positioned in the buried anvil 22.

Thereafter, as shown in FIG. 11, the upper end and the leg 71 of the sleeve member 72 and the lower end of the sleeve member 72 and the buried anvil 22 are connected and fixed with main welding, respectively. On the bottom 21).

Wire 86 from chain block 88 is drawn from the suspension point of each product to separate each product that constitutes module A from the suspension balance.

After completing the installation of each product of the module (A), loosen the turnbuckles 82 of the braces 35, and then the braces 35, the legs 32 and the legs 32, and the upper and lower sides of the first balance 12, respectively. The bolts and nuts 41 and 54, which are the fastening means of the beams 33 and 34, are loosened, and the corner anvils 83 are removed to disassemble the first balance 12.

In the course of the mounting and disassembly work, the construction of the building 92 is in progress, and when the ceiling of the installation site is completed or under construction, the components of the disassembled first balance 12 are carried out to the outside through the building 92 to be rebuilt. It is assembled and reused.

When the second balance 11 is also assembled using a bolt and a nut, the second balance 11 is similarly disassembled, taken out, reassembled, and reused.

If an assembly method that cannot be easily disassembled is used, it is divided and taken out.

In the state where there is no ceiling of the mounting place, only the lower beam 34 that interferes with the module A when lifting the suspension balance is separated from the bridge 32 by the crane 90 and the first and second respective balances 11 , 12) are collectively lifted up and taken out of the building, and the first balance 12 is assembled by attaching the lower beam 34 to the legs 32 and reused together with the second balance.

In the situation after the suspension balance is taken out of the building 92 and dismantled, it is as shown in FIG.

In another embodiment of the present invention, as shown in Fig. 14, it can be applied to the situation where both side walls 23 of the building 92 are completed in strength.

The supporting member 24 is fixed to both side walls 23 of the building 92 facing each other at a position higher than the module A using anchor bolts or the like.

On the other hand, the first balance 12 extends to a position where the upper beam 33 can be loaded on the support member 24 at the same time due to the deformation of the leg 32 as the support means to the building 92 as compared to the previous example. .

The extension portion is used as a support means for the building 92.

Since there is no leg 32 as in the previous example, of course, in the present example, there is no lower beam 34, the weight is reduced, and thus many products can be carried in as one module A.

Other than that is the same as the previous example.

Also in the construction method of a nuclear power plant, it is similar to the previous example, and if it explains another point, it is as follows.

That is, each product, such as each device 1 constituting the nuclear power plant, is modularized as in the previous example and suspended with a suspension balance composed of the first balance 12 and the second balance 11. It is lifted up by the crane 90 and descends between both side walls 23 of the building 92.

During the descent, both ends of the upper beam 33 of the first balance 12 are loaded on the backing member 24 and supported from the building 92.

This situation is shown in Fig. 14, and according to that situation module A is still in the air.

Thereafter, as in the previous example, the module A is dropped to install each product constituting the module A.

After the installation is completed, the first balance 12 and the second balance 11 are lifted by the crane 90 in a state where the respective products constituting the second balance 11 and the module A are disconnected. Lift it up and demolish it outside of the building 92 for reuse.

In this demolition, since the 1st balance 12 does not have the lower beam 32 which interferes with the module A at the time of pulling, the disassembly operation is not accompanied with respect to the frame of a suspension balance at all, and the demolition operation is accelerated. .

When the ceiling is made according to the progress of the construction of the building 92, the first balance 12 and the second balance 11 are divided and removed to the outside of the building through the building.

Other contents are the same as the previous example also in the construction method.

In any embodiment, it is universally applicable to the installation of a product family having various center positions, and the setting position of the product family is precisely secured, and the installation structure (structure) member of the plant required for the module method in the conventional method is required. A decrease in quantity can be obtained.

In addition, according to the construction method of the plant using the suspension balance according to the embodiment of the present invention, the relative positional relationship between the products constituting the module does not easily shift even though the quantity of the installation structure (structural) member of the plant is reduced. We can perform installation promptly and can shorten construction period of construction.
