Description

[Detailed Description of the Invention] This invention relates to a sand pumping device when one submersible sewage pump is shared by a plurality of sand settling basins.

A conventional sand lifting device of this type will be explained with reference to FIGS. 1 and 2. In these figures, 1,
2 is a settling basin, a drum 6 is provided on a traveling trolley 5 that runs on rails 4 of a support stand 3 built over these settling basins 1 and 2, and a wire rope 7 wound around this drum 6 is used to collect underwater sewage. A pump 8 is suspended, and a flexible hose 10 communicating with the discharge port of the pump 8 is wrapped around a drum 9 which is coaxially and integrally provided with the drum 6.

In such a conventional sand pumping device, after finishing sand pumping from the sand pumping state of one of the sand settling basins 1 shown in FIG. , the flexible hose 10 is wound up, the pump 8 is pulled up above the settling basin 1, the traveling trolley 5 is moved onto the other settling basin 2, and the wire rope 7 and the flexible hose 10 are removed from the drums 6 and 9. The pump 8 is lowered to the bottom of the sand settling basin 2,
Sand is being pumped.

However, in the conventional sand pumping device described above, since the traveling trolley 5 is provided with the wire rope 7 and the drums 6 and 9 for the flexible hose 10, the traveling trolley 5 is heavy, and the rails 4 supporting it are heavy. There was a problem that the support stand 3 and the like were also increased in size, resulting in high cost.

This idea separates a hoist for suspending a submersible sewage pump via a wire rope and a flexible hose processing means such as a winding device, and this processing means is installed at an appropriate location near the settling basin. The object of the present invention is to solve the above-mentioned conventional problems and provide a sand pumping device for a sand settling pond that can reduce the weight of the hoist and the rails that support it, and thereby reduce the cost.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 3 shows an embodiment of this invention. In FIG. 3, 11 and 12 are sand settling basins, and a hoist rail 13 extending above these settling basins 11 and 12
is fixed to a fixed member. Note that the hoist rail 13 is composed of an I-beam. A hoist 14 is movably supported by the hoist rail 13, and this hoist 14 is provided with a wire drum 15 that is rotated by an electric motor (not shown).
A submersible sewage pump 17 is suspended from 6. Both ends of a trolley traverse cable 18 are connected to one end of the hoist 14. The tensioning weight 21 of the trolley traversing cable 18 is supported by the roller 22 between the guide rollers 19 and 20.
is supported through. One end of a trolley traversing operating cable 23 is connected to the other end of the hoist 14, and this operating cable 23 is wound around an operating cable drum 25 of a winding device 24, which will be described later.

The winding device 24 has an operating cable drum 25 which is pivotally supported on a stand 27 installed near the outside of the sand settling basin 1, and this drum 25 is rotated by a manual winch 28. A hose winding drum 29 and a hose wire drum 30, which rotate separately, are integrally supported, and a flexible hose 31 communicating with the discharge port of the submersible sewage pump 17 is wound around the hose winding drum 29. It is equipped with
A weight wire rope 32 is wound around the hose wire drum 30, and a hose winding weight 33 is connected to the tip of the wire rope 32.
In addition, 34 and 35 in Fig. 3 are the trolley traverse operation cables 2.
3. With the guide roller of the weight wire rope 32,
These are supported by the fixed member 37, and 36 is an oscillating guide roller supported by the hoist 14, on which the flexible hose 31 is supported.

Next, the operation of the sand lifting device of one embodiment configured as described above will be explained. After finishing sand lifting from the sand lifting state of one of the sand settling basins 1 shown in FIG. 3, the wire rope 16 is wound around it by driving the wire drum 15 of the hoist 14.
The submersible sewage pump 17 is pulled up above the settling basin 1. At this time, the flexible hose 31 is wound around the hose winding drum 29 to prevent it from sagging. In addition, this is done by the hose winding weight 33.
This is done by applying a force in the direction of winding up the flexible hose 31 to the hose winding drum 29 via the weight wire rope 32 and the hose wire drum 30. Thereafter, the manual winch 28 is operated to rotate the operating cable drum 25, and the trolley traversing operating cable 23 and the trolley traversing cable 1 are wound around the operating cable drum 25.
8, move the hoist 14 onto the other settling basin 2 along the hoist rail 13, and
The wire rope 16 is let out from the wire drum 15 of No. 4, and the submersible sewage pump 17 is lowered to the bottom of the sand settling tank 2, and the flexible hose 31 is let out from the hose winding drum 29, and the sand pumping from the other sand settling tank 2 is carried out. Do this.

As explained above, the sand pumping device of this invention is
A hoist rail is provided above the plurality of settling basins, and a submersible sewage pump is suspended from the hoist running on the hoist rail via a wire rope so that it can be raised and lowered, and the flexible hose of the submersible sewage pump is disposed of. Since the winding device and fixed piping that are the means are installed near the sand settling basin separately from the hoist, the hoist does not have a flexible hose processing means, so it is lighter and smaller than a conventional traveling trolley. This has the effect of reducing the weight of the hoist rail, thereby reducing costs, and is particularly effective for use in small-scale sand settling ponds.
