Description

[Detailed description of the invention] The present invention relates to a guide pipe fixing device that can easily and reliably attach and fix a guide pipe that is fixed upright in a pump chamber in order to install a pump. The upper end of the guide pipe is attached to the inner surface of the mounting bracket that can be inserted and clamped between the components of the pump chamber, which is constructed by stacking the wall pipe, adjustment ring, lid frame, lid, etc., in order and fixed to the upper part of the pump chamber. This invention relates to a device for fixing a guide pipe in a pump chamber, characterized in that it is constructed with a protruding holder capable of supporting and fixing the guide pipe.

For example, as shown in FIG. 1, when the pump 3 is installed and fixed on the pump mounting base 2 at the bottom of the pump chamber 1, a guide pipe is installed in the pump chamber 1 in order to raise and lower the pump 3 and guide it to a predetermined position. Therefore, conventionally, a support bar 5 or the like is passed between the upper end of the guide pipe 4 and the lid frame 6 or the adjustment ring 10 to hold the pipe 4 and the lid vertically. The support bar 5 was fixedly attached to the frame 6 by welding or anchor bolts, etc., but the support bar 5 was unstable, and workability such as positioning on the inner wall of the adjustment ring and drilling was poor, especially when attaching with anchor bolts. There were drawbacks such as high construction costs.

The guide pipe fixing device according to the present invention is a completely new technology that was developed in view of these drawbacks of the conventional technology. The guide pipe fixing device is constructed by protruding a protrusion that can support and fix the upper end of the guide pipe on the inside surface of the mounting bracket that can be fixed by using the guide pipe. It is designed so that it can be easily and securely fixed in the upright position.

One embodiment of the fixing device according to the present invention will be specifically explained with reference to the drawings. In FIGS. 2 to 4,
7 is a fixing device according to the present invention, and a mounting bracket 8
and a guide holder 9. For example, as shown in FIG. 5, this mounting bracket 8 includes a horizontal plate a whose outer periphery is formed into an arc shape, which can be inserted between the stacked adjustment ring 10 of the pump chamber 1 and the lid frame 6, and an adjustment It is composed of a vertically curved plate b that can be brought into close contact with the inner circumferential surface of the ring 10, and a vertical flat plate c that linearly connects both ends of the vertically curved plate b. Further, the holder 9 is a vertical flat plate c of the mounting bracket 8.
A bracket e is attached to the mounting plate d.
It is constructed by protruding a round rod f having a vertical axis through the .

When using the fixing device according to the present invention, as shown in FIGS. 4 and 5, the plate a of the mounting bracket 8 is inserted between the adjustment ring 10 and the lid frame 6 that constitute the pump chamber 1, and By inserting the ring bolt 12 that interconnects the oblique wall tube 11, the adjustment ring 10, and the lid frame 6 into the bolt hole g drilled in the mounting bracket 8, and screwing the nut 13 onto the upper end of the bolt 12. Then attach the mounting bracket 8 to the lid frame 6 and the ring 10.
The entire fixing device is thereby stably attached to the upper inner circumferential wall of the pump chamber 1, and then the holder 9 is attached to the open upper end of the guide pipe 4 that stands up in the pump chamber 1. By inserting the round rods f, the upper ends of the guide pipes 4 can be supported and fixed.

In the above embodiment, the mounting bracket 8 is inserted between the adjustment ring 10 and the lid frame 6, but this mounting bracket 8 is inserted between the adjustment ring 10 and the lid frame 6, but the mounting bracket 8 is inserted between other components such as the inclined wall pipe 11 and the lid when the ring 10 is not present. It is possible to insert and hold it between the frame 6 and the frame 6.

Since the fixing device according to the present invention has the above-described structure, it can be easily and stably installed on the upper side wall of the pump chamber, and furthermore, it can extremely easily and reliably support and fix the upper end of the guide pipe erected inside the pump chamber. It has the effect that it can be done.
