[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-88133 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, a piping unit, which includes a base and a plurality of pipes supported by the base, is manufactured in advance in a factory and then installed in a predetermined location at a construction site. The pipes in the piping unit are connected to devices such as flow control valves that require maintenance such as replacement, and these devices are located inside the piping unit.

[0005] When performing maintenance on a device, the device must be disconnected from the piping and then removed from the piping unit. However, because the device is attached to the same rack as the piping to which it is connected, removing the device from the piping unit is time-consuming.

[0006] An object of the present disclosure is to easily remove equipment requiring maintenance from within a piping unit, compared to when the equipment is attached to the same frame as the piping. [Means for solving the problem]

[0007] The piping unit structure according to the first aspect is characterized by comprising a piping unit having a stand and a plurality of pipes supported by the stand, equipment that is arranged within the piping unit and is connected to the pipes provided in the piping unit and requires maintenance, and a support portion that supports the equipment so that the equipment can be freely taken in and out of the piping unit when it is disconnected from the pipes.

[0008] According to the above aspect, the support portion supports the equipment so that the equipment can be freely taken in and out of the piping unit. This makes it easier to remove the equipment from the piping unit than when the equipment requiring maintenance is attached to the same rack as the piping.

[0009] The piping unit structure according to the second aspect is characterized in that, in the piping unit structure described in the first aspect, the support portion comprises a plurality of column members extending vertically and a beam member spanning a pair of the column members and extending horizontally, and the equipment is placed on the beam members.

[0010] According to the above aspect, the support unit includes a plurality of vertically extending pillar members and a horizontally extending beam member that is suspended between a pair of pillar members. The equipment is placed on the beam members. By using a pillar-beam structure for the support unit, the support unit can support the equipment even if the equipment has a large mass.

[0011] A piping unit structure according to a third aspect is the piping unit structure according to the first or second aspect, characterized in that the device is a flow rate adjustment valve.

[0012] According to the above aspect, the flow rate adjustment valve is freely removable from the piping unit, which allows the flow rate adjustment valve to be easily removed from the piping unit for maintenance if a foreign object becomes caught in the flow rate adjustment valve. [Effects of the Invention]

[0013] According to the present disclosure, equipment requiring maintenance can be easily removed from within the piping unit compared to when the equipment is attached to the same frame as the piping. [Brief explanation of the drawings]

The pair of auxiliary angle members 56a extend toward the rear in the depth direction, with the other end of each auxiliary angle member 56a connected to the side surface of the angle member 54b. Furthermore, each of the pair of auxiliary angle members 56a has a pair of through holes 58 aligned in the depth direction.

[0026] The auxiliary angle member 56b is a steel member having an L-shaped cross section, and one auxiliary angle member 56b is provided. The auxiliary angle member 56b is arranged so as to span the pair of auxiliary angle members 56a, and both ends of the auxiliary angle member 56b are connected to the middle parts of the pair of auxiliary angle members 56a. The plurality of angle members are connected at their ends by welding or the like.

[0027] The mounting portions 48 are made of sheet metal with the thickness direction facing up and down, and are provided in plurality. The mounting portions 48 are connected by welding to the angle members 54b, 54c, and 54d arranged below in the vertical direction. The mounting portions 48 are rectangular when viewed from above, and each mounting portion 48 has a circular through-hole 48a formed therein. The piping unit 50 can be installed in a predetermined location at a construction site by fastening screws or the like (not shown) through the through-hole 48a to the floor surface.

[0028] -Plumbing 60, 64- As shown in FIGS. 1 and 2, the pipe 60 is disposed at the rear end of the base 52 in the depth direction and is supported by the base 52 using a support member (not shown). The pipe 60 extends from one side in the width direction (the left side in the figure) to the other side in the width direction (the right side in the figure). Specifically, the pipe 60 is U-shaped with an open bottom when viewed from the depth direction, and one end of the pipe 60 in the width direction faces outward in the width direction. Similarly, the other end of the pipe 60 in the width direction faces outward in the width direction. Furthermore, flange portions 60a are formed on both ends of the pipe 60 for connecting to other pipes. Note that mounting holes (not shown) are formed in the flange portions 60a.

[0029] One end of a branch pipe 62 branching off from the main flow path is connected to the other widthwise side of the pipe 60, and the other end of the branch pipe 62 faces outward in the widthwise direction. A flange 62a is formed at the other end of the branch pipe 62 for connection to another pipe. An attachment hole (not shown) is formed in the flange 62a.

[0030] As shown in FIGS. 1 and 2, the pipe 64 is disposed in the front portion of the base 52 in the depth direction and is supported by the base 52 using a support member (not shown). The pipe 64 extends from one side in the width direction (the left side in the figure) to the other side in the width direction (the right side in the figure). Specifically, the pipe 64 is U-shaped with an open bottom when viewed from the depth direction, and one end of the pipe 64 in the width direction faces outward in the width direction. Similarly, the other end of the pipe 64 in the width direction faces outward in the width direction. Furthermore, flange portions 64a are formed on both ends of the pipe 64 for connecting to other pipes. Note that mounting holes (not shown) are formed in the flange portions 64a.

[0031] -Plumbing 66, 68- 1 and 2, the pipe 66 extends in the width direction, is disposed in a central portion in the depth direction and in a lower portion in the up-down direction within the pedestal 52, and is supported by the pedestal 52 using a support member (not shown). Specifically, one end of the pipe 66 is disposed on one side (left side in the figure) of the pedestal 52 in the width direction, and the other end of the pipe 66 is disposed on the central portion in the width direction of the pedestal 52. Furthermore, flange portions 66a are formed on both ends of the pipe 66, respectively, for connecting to other pipes. Note that mounting holes (not shown) are formed in the flange portions 66a.

[0032] The pipe 68 extends in the width direction on the same line as the pipe 66, is disposed in a central portion in the depth direction and in a lower portion in the up-down direction within the pedestal 52, and is supported by the pedestal 52 using a support member (not shown). Specifically, one end of the pipe 68 is disposed in a portion on the other side in the width direction of the pedestal 52 (the right side in the figure), and the other end of the pipe 68 is disposed in the central portion in the width direction of the pedestal 52 and is separated in the width direction from the other end of the pipe 66. Furthermore, flange portions 68a are formed on both ends of the pipe 68, respectively, for connecting to other pipes. Note that mounting holes (not shown) are formed in the flange portions 68a.

[0033] In this way, an area is formed between the pipes 66 and 68, which is open on the front side in the depth direction and in which the flow rate control valve 10 mounted on the cart 30 described later is placed (see Figure 2).

[0034] [Flow control valve 10] The flow control valve 10 is a known automatic flow control valve, and as shown in Figure 3, includes a body 12 through which a fluid flows, and an actuator 14 disposed above the body 12. The flow control valve 10 further includes a plug 16 that extends vertically, is disposed between the actuator 14 and the body 12, and moves up and down due to the driving force of the actuator. The mass of this flow control valve 10 is large, for example, 60 kg or more. The flow control valve 10 is one example of such equipment.

[0035] The body 12 is disposed so as to extend in the width direction, and flange portions 12a for connecting to the pipes 66, 68 are formed at both ends of the body 12 in the width direction. The flange portions 12a are formed with mounting holes (not shown).

[0036] [Cart 30] As shown in Fig. 3, the bogie 30 has a rectangular shape when viewed from above, and includes angle members 32 extending in the vertical direction, angle members 34 extending in the width direction, angle members 36 extending in the depth direction, and rollers 38. In this way, the bogie 30 has a column-beam structure. The bogie 30 is an example of a support part.

[0037] The angle members 32 are steel members with an L-shaped cross section, and four of them are provided. The angle members 32 are arranged at the four corners of the carriage 30, which has a rectangular shape when viewed from above. The angle members 32 are an example of pillar members.

[0038] The angle members 34 are steel members with an L-shaped cross section, and four of them are provided. Each angle member 34 is arranged so as to span the upper or lower end of a pair of angle members 32 lined up in the width direction. The angle members 34 are an example of a beam member.

[0039] The angle members 36 are steel members with an L-shaped cross section, and four of them are provided. Each angle member 36 is arranged so as to span the upper or lower end of a pair of angle members 32 lined up in the depth direction. Furthermore, the angle member 36 arranged on the lower side in the vertical direction has a through hole 36a formed therein that overlaps with the through hole 58 (see FIG. 2) of the auxiliary angle member 56a when viewed from the width direction when the cart 30 is placed inside the piping unit 50 (see FIG. 1). The angle members 36 are an example of a beam member.

[0040] Rollers 38 are provided at the four corners of the carriage 30, and the rollers 38 allow the carriage 30 to move easily.

[0041] The flow rate control valve 10 described above is placed on the angle member 36 of the cart 30, and the flow rate control valve 10 is attached to the cart 30 by a fixing member (not shown), and by releasing the fixing member, the flow rate control valve 10 can be removed from the cart 30. In other words, the flow rate control valve 10 is detachably attached to the cart 30.

[0042] (action) Next, a description will be given of the operation of the piping unit structure 100. Specifically, a description will be given of the process of removing the flow rate control valve 10 arranged in the piping unit 50 from the inside of the piping unit 50.

[0043] When the flow control valve 10 mounted on the carriage 30 is placed in the piping unit 50, the carriage 30 is disposed between a pair of auxiliary angle members 56a, as shown in Fig. 1. Furthermore, a lock pin (not shown) is inserted into a through hole 36a (see Fig. 3) formed in the angle member 36 of the carriage 30 and a through hole 58 (see Fig. 2) formed in the auxiliary angle member 56a. In this way, the carriage 30 is attached to the piping unit 50.

[0044] Furthermore, one flange portion 12a formed on the body 12 of the flow control valve 10 is connected to the flange portion 66a of the pipe 66 using a connector not shown, and the other flange portion 12a is connected to the flange portion 68a of the pipe 68 using a connector not shown.

[0045] When removing the flow control valve 10 from the piping unit 50 for maintenance or the like from this state, first, the connection between the flange portion 12a formed on the body 12 and the flange portions 66a, 68a formed on the piping 66, 68 is released. Furthermore, the lock pin inserted into the through hole 58 of the auxiliary angle member 56a and the through hole 36a of the angle member 36 of the carriage 30 is removed.

[0046] In this state, as shown in FIG. 2, the cart 30 carrying the flow control valve 10 is moved toward the front in the depth direction, whereby the flow control valve 10 carried on the cart 30 is removed from inside the piping unit 50.

[0047] Furthermore, when the flow control valve 10 is placed on a transport cart, as shown in Figure 4, the cart 30 on which the flow control valve 10 is placed is moved below an upper frame 80a extending in the width direction and provided on a gantry crane 80.

[0048] Furthermore, a chain block 84 is attached to the upper end frame 80 a, and a nylon sling 88 wound around a chain 84 a of the chain block 84 is wound around the actuator 14 of the flow rate control valve 10 .

[0049] In this state, the flow rate control valve 10 is detached from the cart 30, and then the chain block 84 is used to lift the flow rate control valve 10 from the cart 30 and place it on a transport cart (not shown).Then, the standalone flow rate control valve 10 is subjected to maintenance.

[0050] On the other hand, when the flow rate control valve 10 is disposed inside the piping unit 50 and attached to the piping unit 50, the above-described steps are carried out in reverse order.

[0051] (summary) As explained above, in the piping unit structure 100, the cart 30 supports the flow control valve 10 so that the flow control valve 10 can be freely taken in and out of the piping unit 50. This makes it easier to remove the flow control valve 10 from the piping unit compared to when a flow control valve requiring maintenance is attached to the same frame as the piping.

[0052] Furthermore, in the piping unit structure 100, the carriage 30 is provided with a plurality of angle members 32 extending in the vertical direction, and angle members 34, 36 that are hung between the pair of angle members 32 and extend in the horizontal direction. The flow control valve 10 is placed on the angle members 36. In this way, the carriage 30 has a column and beam structure, so that the carriage 30 can support the flow control valve 10, which has a large mass.

[0053] Furthermore, in the piping unit structure 100, the flow rate control valve 10 can be freely inserted and removed from the piping unit 50. This allows the flow rate control valve 10 to be easily removed from the piping unit 50 for maintenance if a foreign object becomes caught in the flow rate control valve 10.

[0054] Although the present disclosure has been described in detail with respect to a specific embodiment, it will be apparent to those skilled in the art that the present disclosure is not limited to such an embodiment and that various other embodiments are possible within the scope of the present disclosure. For example, in the above embodiment, the carriage 30 having the rollers 38 moves easily, but the support part that supports the flow rate control valve 10 may be easily moved by providing a slide mechanism or the like.

[0055] Furthermore, in the above embodiment, the flow control valve 10 was used as an example of equipment, but any equipment that is connected to a pipe and requires maintenance may be used, such as a pump or equipment that includes a filter that requires replacement inside.
