[Industrial applications]

 The present invention relates to a guide wire adjusting device for guiding the lifting and lowering of a pump in a manhole.

[0002]

[Prior art]

 The pump (manhole pump) installed in the manhole for pumping and sending water that has flowed into the manhole (manhole pump) is lifted from the bottom of the manhole or suspended on the bottom of the manhole for maintenance and various other needs. It will be done. In this type of manhole pump facility, it has been known that a pipe member is used as a guide member for guiding the up and down movement of the pump.

On the other hand, in this type of manhole pump facility, it has been tried to use a guide wire instead of the above-mentioned pipe material as a guide member for guiding the up and down movement of the pump. With this product, the guide member can be installed simply by performing a simple installation work by stretching the guide wire between the inner bottom of the manhole and the vicinity of the upper opening of the manhole, and when using pipe material as the guide member. It has the advantages that installation work is simpler and the price is lower than that of.

[0004]

[Problems to be solved by the device]

 By the way, when a guide wire is used as the guide member, what kind of structure is adopted to fix the lower end and the upper end of the guide wire in the manhole greatly affects the workability of the guide wire. .

The present invention has been made under the above circumstances, and an object of the present invention is to provide a guide wire adjusting device that can be suitably used for fixing the upper end portion of the guide wire.

[0006]

[Means for Solving the Problems]

 The guide wire adjusting device for a manhole pump according to the present invention has a base portion of a mounting member projecting into the manhole between the upper end of the concrete layer of the manhole wall and the lid receiving frame arranged on the concrete layer. It is inserted and fixed, and a wire holder is attached to the tip of this mounting member so that the height position can be changed. The wire holder guides the pump up and down in the manhole and the lower end is connected to the inner bottom of the manhole. The upper end of the guide wire is connected so that it can be connected.

[0007]

[Action]

 With this configuration, since the base of the mounting member is fixed by being sandwiched between the upper end of the manhole wall concrete layer of the manhole and the lid receiving frame arranged on the concrete layer, the mounting member is fixed. The member can be easily fixed in a short time. Also, by changing the height position of the wire holder attached to the tip of the mounting member, the length of the guide wire whose upper end is connected to the wire holder is adjusted.

【Example】

 FIG. 1 is a vertical sectional front view of a manhole in which a guide wire 9 is installed using a guide wire adjusting device A according to an embodiment of the present invention. Invert, 3 is a bend pipe, 4 is a pump (submersible pump), 5 is a pump pipe, 6 is a check valve, 7 is a discharge header pipe, 8 is a drain pipe, 11 is a water inlet pipe, and the pump 4 The discharge port of is connected to the discharge curved pipe 3. Further, an iron lid receiving frame 13 is arranged on the upper end portion of the body wall concrete layer 1, and a manhole lid 14 is attached to and detached from the lid receiving frame 13.

In such a manhole pump facility, the water flowing into the manhole from the inflow pipe 11 is sucked from the suction bell 4A of the pump 4 arranged in the recess 2A of the invert 2, and the discharge port and the discharge curve are discharged. The water is pumped to a predetermined height through the pipe 3 and the water pump 5, and then discharged through the discharge header pipe 7 and the drain pipe 8. In this manhole pump facility, the two pumps 4 are installed at positions where they do not interfere with each other, and the two pumps are operated simultaneously or separately during pumping and drainage.

Guide wires 9, 9 are individually stretched over the two pumps 4, 4 between the upper opening 12 of the manhole and the bottom of the manhole, for example, the invert 2. The guide wires 9, 9 are provided to guide the lifting and lowering of the pumps 4, 4.

2 and 3 show a mounting state of the guide wire adjusting device A according to the embodiment of the present invention, and FIG. 4 shows a mounting member 15 which will be described later. The guide wire adjusting device A includes a mounting member 15, a wire holder 16 and a connecting mechanism 17 for connecting both members. As shown in FIG. 4, the mounting member 15 has a substantially rectangular shape in plan view, and the base 19 having the long holes 18 and 18 at the corners is the upper end of the concrete wall 1 of the trunk wall as shown in FIG. It is sandwiched and fixed between the part and the lid receiving frame 13. In the illustrated example, a predetermined number of spacers 20 ... Are interposed between the base 19 and the lid receiving frame 13, and a mortar layer 21 is loaded around the spacers 20.

As shown in FIG. 2, the tip of the mounting member 15 projects into the manhole, and the wire holder 16 is attached to the tip of the manhole through the coupling mechanism 17. The connecting mechanism 17 cooperates with the bolt body 23 inserted into the hole 22 provided in the mounting member 15 and the head portion 23a of the bolt body 23 screwed into the bolt body 23 to sandwich the mounting member 15. The fixing nut 24 is attached, and the support nut 25 and the tightening nut 26 screwed into the bolt body 23 are provided.

The wire holder 16 includes a plate-shaped holder main body 28 having cylinders 27a, 27b, 27b at the top and left and right sides, and a bracket 29 protruding from the holder main body 28. A hole (not shown) formed in 29 is inserted into the bolt body 23, supported by a support nut 25, and fixed by a tightening nut 26.

In this embodiment, two pumps 4 are installed, and a guide wire 9 is stretched separately for each of the two pumps 4, 4. Therefore, the connecting mechanisms 17, 17 are attached to the tip of the attachment member 15 so as to be divided into the right and left, and the wire holders 16, 16 are attached to the respective connecting mechanisms 17, 17. Further, two bolt bodies 23, 23 are used for each coupling mechanism 17 to increase the suspension strength. The mounting member 15 is provided with hooks 31 and 32 for hooking the power supply cable, the pump sling 10, and the like, a reinforcing member 33, and the like. Further, the holder body 28 is also provided with a reinforcing material 34.

With the configuration described above, the guide wire adjusting device A has the base portion 19 of the mounting member 15 sandwiched between the upper end portion of the manhole wall concrete layer 1 of the manhole and the lid receiving frame 13 made of an iron frame. Since it is embedded and fixed, the fixing work can be performed easily. Further, when the height position of the holder main body 28 is changed by loosening the tightening nut 26 and turning the support nut 25 to the right or left, the distance between the holder main body 28 and the invert 2 at the bottom of the manhole is increased or decreased. Therefore, as shown in FIG. 2 and FIG. 3, from the upper end to the lower end (connected to the invert side) of the guide wire 9 whose upper end is passed through the cylinders 27a, 28b, 28b of the holder main body 28. It is possible to adjust the length of the steplessly.

Note that, in FIG. 3, the alternate long and short dash line C-C indicates the center line.
