Description

Fig. 3 the object of Fig. 2 seen from above and

F i g. 4 shows an alternative embodiment in a vertical section.

In the shaft opening of a twin pump station shown in FIG. I, there are upper mountings 4 and 5 of essentially straight guide tubes arranged in the corners of the opening 1 and rotated in relation to the lower guide brackets so that pumps 2 and 3 are lifted or lowering in a helical path around a vertical axis between a lower, pivoted position 10 and an upper, inwardly pivoted position 11 slide, so that the small opening 1 of the shaft is still sufficiently large. Optionally, this can be a pipe a guide device and the other pipe in a helical line around the The first-mentioned guide tube run, the guide devices for the pumps are marked with 6, 7 or 8, 9 designated.

The shaft 13 of the pump station (FIGS. 2 and 3) is closed at the top by a cover 18. Right away The upper brackets 4 and 5 are arranged under the cover 18 in two corners of the opening 1, which hold the somewhat flexible guide tubes of the guide device 6, 7 or 8, 9. the Brackets 4 and 5 are here in relation to the associated connecting piece 14 and 15 for the outlet flange 16 or 17 of the pump 2 or 3 rotated.

The pump 3 is shown with dash-dotted lines in the lower, outwardly pivoted position 10, which corresponds to the working position. The outlet flange 17 of the pump 3 lies on the pipe flange 19 of the connection piece IS. When the pump 3 is hoisted up, it slides with one Slide shoe 12 along the pipes of the guide device 8, 9 becomes the center of the shaft opening pivots and finally takes the upper one, shown with solid lines, inward to the middle directed position 11, in which the outlet flange 17 of the pump a certain angle to Connecting flange 19 of connecting piece 15 forms.

The guide devices according to FIG. 4 are inclined and converge upwards. Each guide device can, for example, consist of two tubes or an I-P fil carrier, T-profile carrier or the like exist and run completely straight over the entire length. Especially when the upper, narrower shaft part has a greater height, the guide device is expediently with Bucket kink or executed in a soft curve, the two guide devices can run parallel to each other in the upper part.

The sliding shoes 12 and the pipe connections of the pumps 2 and 3 are in a suitable manner and Way trained. The same applies to the lifting and lowering devices, which are known in the art and Way can be carried out and are also not shown in the drawing.
