Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a support structure for an electric motor in a pump device.

[Conventional technology]

In the conventional pump device illustrated in FIGS. 8 to 10, a pump casing c is erected on a base d, and a pump portion b housed in the pump casing c is connected to an electric motor a directly connected to the pump casing c. It is connected. However, in the case of such a configuration, the electric motor a is connected to the pump casing c only at one end, and the other end is separated from the base d, so that the self-standing of the pump casing c is unstable, and mainly during transportation. Since vibration or the like acts on the above, there is a concern that stress concentrates on the connecting portion between the electric motor a and the pump casing c.

In order to assist the support of such a cantilever-supported motor, a height-adjustable support bolt e is erected on the base d,
When the electric motor a is connected to the pump casing c, the height of the support bolt e is adjusted so that the upper end portion abuts the lower surface of the electric motor a, whereby the support bolt e supports the electric motor a. ing.

With this configuration, the support bolt e erected on the base d partially bears the load of the electric motor a. Therefore, when the electric motor a is connected to the pump casing c, the electric motor a and the pump casing c are connected. It is possible to reduce the occurrence of stress in the place. Further, in the case of such a structure, when the pump casing c to which the pipe is connected is left attached to the base d and the pump portion b and the electric motor a are directly connected to each other for maintenance or the like, the pump casing c is detached from the pump casing c. The support bolt e can support the weight of the electric motor a and the pump portion b, and can be pulled out without being overwhelmed by the mutual fitting portion of the pump portion b and the pump casing c.

[Problems to be solved by the device]

However, when the electric motor a is removed from the pump casing c, the load of the electric motor a or the electric motor a and the pump portion b can be supported by the support bolt e, but since the support bolt e has a small support area, it is necessary to add a hand. is there.
In such an unstable state, it is necessary to manually separate the electric motor a or the electric motor a and the pump portion b from the pump casing c, and this work is not easy. That is, when the electric motor a and the pump portion b, which are still directly connected to each other as described above, are supported by the single support bolt e in a state where the electric motor a and the pump portion b are detached from the pump casing c, it is extremely unstable even if a human hand is added. This is unavoidable, especially when the weight of the electric motor a is considerably large, or when a control panel f or the like is arranged in the vicinity of the electric motor a as illustrated in FIGS. 11 and 12. Since the work is difficult, the electric motor a may be dropped from the support bolt e, and the electric motor a or the pump part b may be damaged, or an accident such as an injury to a worker may occur.

The present invention has been made to solve the above-described problems, and provides a support structure for an electric motor in a pump device that can reliably support the electric motor in a stable state removed from the pump casing. With the goal.

[Means for Solving the Problems]

According to the present invention, the base is provided with a height-adjustable support bolt for supporting the load of the electric motor in a state where the electric motor is connected to the pump casing, and the base is provided in the lateral direction with respect to the axial direction of the electric motor. A supporting tool that has an extending arm and supports the electric motor by the arm when the electric motor is detached from the pump casing is provided separately from the support bolt.

[Action]

As described above, in the present invention, since the base is provided with the supporting member for supporting the electric motor separately from the support bolt, when the electric motor is detached from the pump casing, the supporting member can support the electric motor. In this case, the support includes an arm extending laterally with respect to the axial direction of the electric motor,
The electric motor transferred to the support tool is supported by the arm portion of the support tool, so that the motor is reliably supported in a stable state without the need for human hands.

〔Example〕

The present invention will be described below with reference to an embodiment shown in the drawings.

In the pump device 6 shown in FIGS. 2 and 3, a pump casing 9 is fixed to an upper surface of one end of a base 10, and an electric motor 7 is detachably connected to the pump casing 9 at one end thereof. The pump casing 9 accommodates a pump portion 8 directly connected to the electric motor 7. When the electric motor 7 is removed from the pump casing 9, the pump portion 8 can also be removed from the pump casing 9 integrally with the electric motor 7. It is like this.

On the upper surface of the base 10, a support bolt 11 is provided which is located below the electric motor 7 and supports the electric motor 7 when the electric motor 7 is connected to the pump casing 9. As shown in FIGS. 3 and 4, the height of the support bolt 11 can be adjusted, and when the electric motor 7 is connected to the pump casing 9, the height is adjusted so that the upper end surface of the support bolt 11 is adjusted to the electric motor 7.
The lower surface of the electric motor 7 is brought into contact with the lower surface of the electric motor 7, thereby partially supporting the load of the electric motor 7 to support the electric motor 7.

Further, a support 1 that is located below the electric motor 7 and is separate from the support bolts 11 is attached to the upper surface of the base 10. As shown in FIG. 1, the support tool 1 includes a base portion 2 formed of a plate-like material and an arm portion 3 extending laterally at right angles to the axial direction of the electric motor 7, both of which are provided. It is connected by welding. In the illustrated example, the base portion 2 has a substantially U shape and the arm portion 3 has an arc shape, and is attached to the base 10 via a mounting bolt 4 penetrating the base portion 2.

The support 1 is attached to the base 10 by the attachment bolts 4 so that the arm 3 extends laterally below the electric motor 7. In this case, when the electric motor 7 connected to the pump casing 9 is supported by the support bolts 11 in a regular mounting state, the upper surface of the arm 3 of the support 1 and the electric motor 7 are supported.
An appropriate gap 12 is provided between the lower surface and the lower surface.

In the above-described embodiment, when the electric motor 7 and the pump portion 8 are connected to the pump casing 9 in the normal mounting state, the lower surface of the electric motor 7 is in contact with the top portion of the support bolt 11, and It is separated from the arm 3.

As shown in FIG. 4, when the electric motor 7 or the electric motor 7 and the pump portion 8 are removed from the pump casing 9 for maintenance or the like, as a general rule, the fitting between the pump casing 9 and the pump portion 8 is substantially disengaged. Until then, keep the support bolt 11 high and use the support bolt 11 to drive the electric motor 7
Alternatively, the electric motor 7 and the pump unit 8 are supported. When the pump casing 9 and the pump portion 8 are disengaged from each other, the fourth
As shown in the figure, the height of the support bolts 11 is lowered, and the electric motor 7 and the pump portion 8 are transferred to the support 1 so as to be supported.

Needless to say, the support 1 preferably supports the position corresponding to the center of gravity of the electric motor or the like when the electric motor 7 is supported. The support can be performed reliably and stably without human support, so that maintenance work can be performed safely and easily even under adverse conditions.

The electric motor 7 or the electric motor 7 and the pump unit 8 are carried to a desired place by a proper means and carried out a predetermined work when necessary for inspection, maintenance, repair, etc., and after the work is completed, the above-mentioned operation is performed. You can recover in almost the reverse procedure.

The present invention is not limited to the above-described embodiment. For example, the arm 3 of the support 1 is substantially U-shaped as shown in FIG. 5 and C-shaped as shown in FIG. As shown in FIG. 7, it may be a V-shape or the like, or may be an appropriate shape corresponding to the size and weight of the electric motor 7.

Besides, various modifications and applications are possible within the scope of the gist of the present invention.

[Effect of device]

As described above, according to the present invention, the support bolt is provided on the base and the support tool is provided separately from the support bolt.
The support bolts may support the electric motor when the electric motor is connected to the pump casing, and the support may support the electric motor when the electric motor is removed from the pump casing.

When the electric motor is supported by the support bolts, by adjusting the height of the support bolts and hitting the electric motor, it is possible to surely bear a part of the load of the electric motor by the support bolts. It is possible to prevent stress from concentrating on the connection points.

When the electric motor is removed from the pump casing, the electric motor can be transferred from the support bolt to the support and supported, and in this case, the support includes an arm portion extending laterally with respect to the axial direction of the electric motor. Therefore, the electric motor transferred to the support can be supported by this arm portion, and the electric motor can be reliably supported in a stable state without the need to put hands on the electric motor.

As a result, the work is facilitated, and it is possible to prevent accidents such as dropping the electric motor from the support bolts, damaging the electric motor or the pump portion, and injuring a worker.
