FIG. 6 is a perspective view showing an example of the operation of removing the motor 32 from the gantry unit 1.

[0012] As shown in Figures 1 and 2, the mounting unit 1 comprises a mounting stand 4 having a plurality of pillars 16 each having an arrangement space 15 therein and a mounting portion 13 provided on the upper portion of the plurality of pillars 16, an object to be placed 32 to be placed in the arrangement space 15, and an object to be placed 9 to be placed on the mounting portion 13.

[0013] In this embodiment, the stand unit 1 will be described as an example of a fire pump unit having a motor, which is an example of the object to be placed 32, and a priming tank, which is an example of the object to be placed 9. In the following description, the stand unit 1 will be described as the fire pump unit 1, the object to be placed 32 as the motor 32, and the object to be placed 9 as the priming tank 9.

[0014] 1 to 3, the fire pump unit 1 includes a base 2, a first fixing member 3, a stand 4, a pump device 5, piping 6, a performance test device 7, a control panel 8, and a priming tank 9. The fire pump unit 1 is provided with a water discharge means such as a sprinkler or a fire hydrant on the secondary side.

[0015] The base 2 is fixed to an installation location where the fire pump unit 1 is installed. The base 2 is formed, for example, in a rectangular frame shape that is long in one direction. This one direction is, for example, the direction in which a pump 31 and a motor 32 (described later) of the pump device 5 are arranged, and is the axial direction of the main shaft of the motor 32.

[0016] 3, the base 2 has holes 11 in multiple locations, for example, four locations. The holes 11 are formed at locations on the upper surface of the base 2 where the support posts 16 are arranged. For example, one hole 11 is formed at each end in the width direction of the base 2 at one end in the longitudinal direction. In addition, one hole 11 is formed at each end in the width direction of the base 2 at the other end in the longitudinal direction.

[0017] The first fixing member 3 is, for example, a bolt, and fixes the mount 4 to the base 2 .

[0018] As shown in FIGS. 1 to 3, the mount 4 includes a mounting portion 13, a plurality of support columns 16, and a second fixing member . The mounting portion 13 is formed, for example, in a frame shape. The mounting portion 13 is formed so that the priming tank 9 can be placed thereon. The upper surface of the mounting portion 13 is a mounting surface on which the priming tank 9 can be placed.

[0019] The plurality of pillars 16 are formed in a shape extending in the vertical direction. A mounting portion 13 is provided on the upper portion, for example, the upper end portion, of the plurality of pillars 16. Inside the plurality of pillars 16 is an arrangement space 15 in which a motor 32 can be arranged. The plurality of pillars 16 is, for example, four pillars 16.

[0020] The four support columns 16 are arranged at intervals in the circumferential direction of the arrangement space 15. In this embodiment, the four support columns 16 are arranged, for example, at the corners of a rectangle. Two support columns 16 are fixed to both ends in the width direction of one end in the longitudinal direction of the base 2. The remaining two support columns 16 are fixed to both ends in the width direction of the other end in the longitudinal direction of the base 2. There is a gap between two adjacent support columns. 3, the support pillar 16 includes, for example, a base portion 17 and a support pillar body 18. The base portion 17 is placed on the upper surface of the base 2 and fixed to the base 2 by a first fixing member 3. The base portion 17 is formed, for example, in the shape of a flat plate having a hole 17a through which the bolt 3 can be inserted.

[0021] The support body 18 is formed, for example, in a shape extending in the vertical direction. The support body 18 has a height that allows the motor 32 to be arranged in the arrangement space 15 in a horizontal position. The support body 18 has, for example, a first vertical wall 20a and a second vertical wall 20b, and both the surface facing outward and the surface facing inward have two intersecting planes. Here, the outward side means the side outward from the arrangement space 15, and the inward side means the side toward the arrangement space 15. The support body 18 is formed, for example, from an angle material having an L-shaped cross section perpendicular to the longitudinal direction.

[0022] When the motor 32 is removed between two adjacent pillars 16 among the multiple pillars 16, the pillar 16 facing the motor 32 in the removal direction is configured so that at least the portion facing the motor 32 can be retracted relative to the motor 32.

[0023] In this embodiment, as an example of retraction, at least a facing portion that faces the motor 32 in the removal direction can be retracted from the motor 32 by being separated from the other portion of the gantry 4.

[0024] In this embodiment, the motor 32 is inserted into and removed from the arrangement space 15, for example, through a gap between two support columns 16 arranged at one end in the longitudinal direction of the base 2. One of the two support columns 16 faces the motor 32 in the passing direction.

[0025] The support pillar 16 facing the motor 32 in the passing direction is referred to as the detachable support pillar 16A. Of the multiple supports 16, the supports 16 other than the detachable support pillar 16A are formed so as to be able to stably support the priming tank 9 when the motor 32 is removed, even if all or a part of the detachable support pillar 16A is separated from the rack 4. In this embodiment, the priming tank 9 does not contain water when the motor 32 is removed.

[0026] The detachable column 16A is configured so that all or a part of it can be separated from the mount 4. In this embodiment, as shown in FIG. 3, the detachable column 16A is formed so as to be divisible into a plurality of parts. Among the divided parts, one including an opposing part is formed so as to be detachable from the other part of the detachable column 16A. Here, among the divided parts of the detachable column 16A, one including an opposing part is referred to as a detachable part 22. There may be one or more detachable parts 22. In this embodiment, the detachable column 16A is divided into two in the longitudinal direction, with the lower part being the detachable part 22 and the upper part being the other part 23.

[0027] The detachable part 22 includes a first pillar body 18a constituting a part of the pillar body 18, and a first end wall 24 provided at one end of the first pillar body 18a on the other part 23 side. The first end wall 24 is formed in a plate shape, for example, perpendicular to the longitudinal direction of the pillar 16. The first end wall 24 is formed in a rectangular shape with the first vertical wall 20a and the second vertical wall 20b disposed at the edge. As shown in FIG. 4, the first end wall 24 has a hole 24a penetrating the longitudinal direction of the pillar 16. The surface on the other part 23 side, which is the upper surface of the first end wall 24, is formed in a plane perpendicular to the longitudinal direction of the pillar 16. In addition, this surface becomes a plane perpendicular to the up-down direction when the detachable part 22 is fixed to the other part 23.

[0028] The other part 23 includes a second pillar body 18b constituting the other part of the pillar body 18, and a second end wall 25 provided at one end of the second pillar body 18b on the side of the detachable part 22. The second end wall 25 is formed, for example, in a rectangular plate shape similar to the first end wall 24. The second end wall 25 is formed with a hole 25a penetrating the longitudinal direction of the pillar 16. The lower surface of the second end wall 25 is formed in a plane perpendicular to the longitudinal direction of the pillar 16. In addition, the lower surface of the second end wall 25 is a plane perpendicular to the up-down direction. The lower surface of the second end wall 25 is in surface contact with the upper surface of the first end wall 24 when the detachable part 22 is fixed to the other part 23.

[0029] The second fixing member 14 detachably fixes the detachable part 22 to the other part 23. As shown in Fig. 4, the second fixing member 14 includes, for example, a bolt 26 and a nut 27. The bolt 26 fixes the detachable part 22 and the other part 23 in a position along the longitudinal direction of the support 16. Specifically, the bolt 26 is inserted through the hole 24a of the first end wall 24 and the hole 25a of the second end wall 25 in a position along the longitudinal direction of the support 16, and is screwed into the nut 27 to fix the detachable part 22 to the other part 23.

[0030] 1 to 3, the pump device 5 is placed on and fixed to the base 2. The pump device 5 includes a pump 31 and a motor 32. The pump 31 is disposed on the other end side of the stand 4 of the base 2, for example.

[0031] A cable 35 is connected to a terminal block 34 which is a part of the motor 32. The cable 35 is connected to a control panel 8. For example, the terminal block 34 which is a part of the motor 32 is disposed between the detachable support column 16A and the other support column 16 in the longitudinal direction of the base 2. When the motor 32 is inserted or removed from the arrangement space 15, the terminal block 34 faces the detachable support column 16A in the insertion / removal direction.

[0032] The piping 6 constitutes a flow path connecting the pump 31 and the priming tank 9, and a flow path on the secondary side of the pump 31. In addition, the flow path of the piping 6 connecting the priming tank 9 and the pump 31 has an orifice, and is formed so that a part of the water pressurized by the pump 31 can be throttled and released to the priming tank 9 in order to suppress a temperature rise in the pump 31.

[0033] The performance test device 7 is provided on the piping 6. The performance test device 7 is, for example, a piping equipped with a flow meter that is connected to the piping 6.

[0034] The control panel 8 is disposed on the side of the pedestal 4. The control panel 8 is fixed to the pedestal 4, for example.

[0035] Next, an example of the operation of removing the motor 32 from the arrangement space 15 of the pedestal 4 will be described with reference to Figs. 4 to 6. Note that before removing the motor 32, an operation of making the motor 32 in a state in which it can be removed is completed. Here, the state in which it can be removed is, for example, a state in which the motor 32 is disconnected from the pump 31 and the motor 32 is disconnected from the control panel 8.

[0036] The worker first removes the detachable portion 22 of the detachable column 16A from the other portion 23. The worker releases the fixation of the detachable column 16A and the base 2 by removing the first fixing member 3. Next, as shown in FIG. 4, the worker releases the fixation of the detachable portion 22 and the other portion 23 of the detachable column 16A by removing the second fixing member 14. The worker performs the work of removing the second fixing member 14 from the outside of the stand 4.

[0037] Next, the worker removes the detachable part 22 from the stand 4 by, for example, moving it outward along the horizontal direction as shown in Fig. 5. After removing the detachable part 22, the worker removes the motor 32 by passing it between the two support columns 16 arranged at one end in the longitudinal direction of the base 2 as shown in Fig. 6. In this manner, the removal work of the motor 32 is completed.

[0038] When installing the motor 32 in the arrangement space 15, the worker removes the detachable part 22 from the other part 23 as described above, and then moves and installs the motor 32 in the arrangement space 15 through between the two support columns 16 arranged at one end of the base 2 in the longitudinal direction. Next, when the motor 32 is installed in the arrangement space 15, the worker places the detachable part 22 below the other part 23. Next, the worker fixes the detachable part 22 and the other part 23 with the second fixing member 14. Next, the worker fixes the detachable support column 16A to the base 2 with the first fixing member 3. In this manner, the arrangement work of the motor 32 is completed.

[0039] In the fire pump unit 1 configured in this manner, the motor 32 can pass between the two columns 16 by removing the detachable portion 22 of the detachable column 16A. Therefore, the size of the stand 4 does not need to be increased to widen the space between the two columns 16 to allow the motor 32 to pass through. Furthermore, the motor 32 can be removed from the arrangement space 15 by simply removing the detachable portion 22 without removing the priming tank 9 from the mounting portion 13 and removing the stand 4 from the base 2, so that the efficiency of the work of removing the motor 32 from the arrangement space 15 can be improved. As a result, the efficiency of the maintenance work of the motor 32 performed by removing the motor 32 from the arrangement space 15 can be improved. Similarly, the efficiency of the work of installing the motor 32 in the arrangement space 15 can also be improved.

[0040] In this way, the fire pump unit 1 makes it possible to efficiently remove the motor 32 arranged inside the pedestal 4 while preventing the unit from becoming too large.

[0041] In addition, the end walls 24, 25 are exposed to the outside. Therefore, the second fixing member 14 that fixes the detachable part 22 and the other part 23 can be operated from the outside of the stand 4, making it easy to attach and detach the detachable part 22 to the other part 23.

[0042] Moreover, the first end wall 24 and the second end wall 25 abut against the support pillar 16 in the longitudinal direction. The bolt 26 of the second fixing member 14 is inserted through the holes 24a, 25a along the longitudinal direction of the support pillar 16. For this reason, when the detachable part 22 is fixed to the other part 23, the first end wall 24 and the second end wall 25 abut against each other in the vertical direction to support the detachable part 22. Therefore, the position of the detachable part 22 is unlikely to shift during the operation of fixing the detachable part 22 to the other part 23, and therefore the operation of fixing the detachable part 22 and the other part 23 with the second fixing member 14 can be easily performed.

[0043] In this way, according to the present embodiment, it is possible to provide the pedestal 4 and the fire pump unit 1 that enable the motor 32 to be removed from the pedestal 4 efficiently while preventing an increase in size.

[0044] The present invention is not limited to the above-described embodiment. For example, as shown in Fig. 7, a movement restricting portion 41 may be provided on one of the detachable portion 22 and the other portion 23. The movement restricting portion 41 restricts movement of the detachable portion 22 relative to the other portion 23 by contacting the other of the detachable portion 22 and the other portion 23 in a direction intersecting the longitudinal direction of the support 16, for example, in a direction perpendicular thereto. The movement restricting portion 41 contacts the other in at least one direction intersecting the longitudinal direction of the support 16.

[0045] The movement restricting portion 41 is provided, for example, on the other portion 23. The movement restricting portion 41 protrudes from the other portion 23 toward the detachable portion 22 in the longitudinal direction of the support 16. The movement restricting portion 41 abuts against the other portion 23 in a direction perpendicular to the longitudinal direction of the support 16, thereby restricting the movement of the detachable portion 22 beyond the position where the hole 24a and the hole 25a face each other.

[0046] In addition, the first surface 41a of the movement restricting portion 41 facing the detachable portion 22 has two planar portions that are aligned in the circumferential direction and intersect with each other. The first surface 41a has a first planar surface 41a1 and a second planar surface 41a2 that imitate the surfaces of the first vertical wall 20a and the second vertical wall 20b of the detachable portion 22 on the arrangement space 15 side. In other words, the second surface 22a facing the first surface 41a is formed as a surface that imitates the first surface 41a. In further other words, the second surface 22a has two planar portions that are aligned in the circumferential direction and intersect with each other. The first surface 41a and the second surface 22a are formed so that the hole 24a and the hole 25a face each other when they come into surface contact with each other.

[0047] In this way, the first surface 41a of the movement restricting portion 41 has two planar portions that are aligned circumferentially and intersect with each other, and the second surface 22a of the detachable portion 22 is formed into a surface that conforms to the first surface 41a, making it possible for the movement restricting portion 41 to align the detachable portion 22 with the other portion 23.

[0048] A rotation restricting portion may be provided on one of the detachable portion 22 and the other portion 23. The rotation restricting portion restricts rotation of the detachable portion 22 relative to the other portion 23 by abutting against the other of the detachable portion 22 and the other portion 23 in the circumferential direction.

[0049] In this embodiment, the movement restricting portion 41 also functions as a rotation restricting portion. That is, a corner portion 19 of the second surface 22a of the detachable portion 22 fits into a ridge portion 42 between two flat portions of the first surface 41a of the movement restricting portion 41, so that when the detachable portion 22 is rotated relative to the other portion 23, the corner portion 19 abuts against the ridge portion 42. As a result, the rotation of the detachable portion 22 relative to the other portion 23 is restricted. Note that the configuration of the rotation restricting portion is not limited to the movement restricting portion 41.

[0050] Such a movement restricting portion 41 is configured by fixing a member separate from the support 16 to the peripheral surface of the detachable portion 22 or the other portion 23, as shown in Fig. 7 for example. Alternatively, the movement restricting portion 41 is configured by fixing a member integral with or separate from the end walls 24, 25 of the detachable portion 22 or the other portion 23, as shown in Fig. 8 for example. Note that Fig. 8 shows a configuration in which the movement restricting portion 41 is formed integrally with the second end wall 25, as an example.

[0051] In the above example, the detachable part 22 and the other part 23 are fixed with the bolt 26 in a position along the longitudinal direction of the support 16, but the present invention is not limited to this example. In another example, the bolt 26 may fix the detachable part 22 and the other part 23 in a position along a direction intersecting the longitudinal direction of the support 16, for example, a direction perpendicular to the longitudinal direction of the support 16.

[0052] 9, a fixing plate member 52 having a hole 51 formed therethrough in a direction perpendicular to the longitudinal direction of the support 16 is fixed to the lower end of the other part 23, and a hole 53 is formed in the upper end of the detachable part 22 so as to penetrate in a direction perpendicular to the longitudinal direction of the support 16, and the detachable part 22 and the other part 23 may be fixed by passing a bolt 26 through the holes 51 and 53 and screwing the bolt 26 into a nut 27. Alternatively, the fixing plate member 52 may be fixed to the upper end of the detachable part 22, and the hole 53 may be formed in the lower end of the other part 23.

[0053] In the above example, the detachable column 16A is configured to be detachable from the base 4, but is not limited thereto. In another example, the detachable column 16A is configured to be detachable from the base 4, as shown in FIG.

[0054] In the above example, the pedestal 4 is described as having four columns 16, but is not limited thereto. The pedestal 4 may be configured to have two or three columns 16, or may be configured to have five or more columns 16.

[0055] In the above example, one of the multiple pillars 16 of the gantry 4 is the detachable pillar 16A, but the present invention is not limited to this. The gantry 4 may be configured to include multiple detachable pillars 16A.

[0056] In the above example, the fire pump unit 1 has been described as an example of the pedestal unit 1, but the present invention is not limited thereto. The pedestal unit 1 may be a pump unit other than the fire pump unit. For example, the pedestal unit 1 may be a pump unit that does not include the priming tank 9 and includes an accumulator placed on the placement portion 13. Alternatively, the fire pump unit 1 may be configured other than a pump unit.

[0057] In the above example, the detachable part 22 is detachable from the detachable column 16A, but the present invention is not limited to this. For example, the detachable column 16A may be bent to retreat to a position where it does not interfere with the motor 32. Alternatively, the detachable column 16A may be configured to be slidable with respect to the placement part 13 and the base 2, and may be configured to be movable to a position where it does not interfere with the motor 32. In this way, it is sufficient that the detachable column 16A or the detachable part 22 is retreatable.

[0058] The present invention is not limited to the above-mentioned embodiment, and can be modified in various ways without departing from the gist of the present invention. The embodiments may be combined as appropriate, and in that case, the combined effect can be obtained. Furthermore, the above-mentioned embodiment includes various inventions, and various inventions can be extracted by combinations selected from the multiple components disclosed. For example, if the problem can be solved and the effect can be obtained even if some components are deleted from all the components shown in the embodiment, the configuration from which the components are deleted can be extracted as an invention.
