Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a suspension structure for a portable submersible pump.
[0002]
[Prior art and its problems]
When installing the submersible pump for equipment in the pit and when lifting it from the pit, a suspension chain is generally used. In particular, in the case of submersible pumps for equipment equipped with a detachable device, a hanging chain is attached to the pump body, but in order to smoothly engage this pump body with the fixed part in the pit, Must be held vertically or slightly forward tilted.
[0003]
As shown in FIG. 6, the conventional hanging chain is a group of two chains 90a and 90b moored by eyebolts 80a and 80b standing in two directions on the upper surface 60 of the pump, into one hanging chain 90c. Thus, it has a reverse Y-shape, and this is lifted and lowered by a manual or automatic winding mechanism. However, the individual metal rings constituting the two chains 90a and 90b are formed by bending a metal wire cut into a certain length into a ring shape, and there are slight variations in the finished dimensions. Therefore, since the lengths of the chains 90a and 90b formed by connecting these metal rings are somewhat uneven, it is difficult to suspend the pump body vertically or slightly forwardly, and it is often an undesired direction. It may be difficult to attach and detach the pump body to the fixed part in the pit.
[0004]
Moreover, in the portable submersible pump, the above-described eyebolts or the like are not provided, and the weight is light, and the pump is often hung with a rope tied to the pump holder. However, the conventional lender does not have a function to stabilize the rope at a fixed position, so the pump's center of gravity is not fixed at the time of suspension, and the pump tilts in an unexpected direction. There is a risk that the rope will be untied or the rope will be broken.
[0005]
OBJECT OF THE INVENTION
An object of the present invention is to provide a suspension structure for a portable submersible pump that does not require an eyebolt or the like for mooring a chain and that can be lifted and lowered safely and easily with a rope stably. .
[0006]
[Structure of the invention]
In the hanging structure of the portable submersible pump according to the present invention, a handle having a space portion formed below the grip portion using the upper edge portion as a grip portion and leg portions guided from both ends thereof as fixing portions. Is fixed to the upper surface of the pump, and a plurality of through holes extending from the upper surface to the lower surface of the grip portion are provided for engaging the hanging rope, and the tip of the hanging rope introduced from one through hole The part is led out from the other through hole and fastened on the grip part.
[0007]
【Example】
The embodiment will be described below with reference to FIGS.
[0008]
1 is a handle used when carrying the pump. The upper edge portion is a grip portion 2, and bolt holes 4 and 4 are provided in the leg-like portions 3 and 3 guided from both ends thereof to form a fixing portion. The space portion 7 is formed below the grip portion 2 by being fixed to the pump upper surface 6 by the fasteners 5 and 5. Reference numerals 8 a and 8 b denote a plurality of through holes provided so as to communicate from the upper surface to the lower surface of the grip portion 2, and these through holes 8 a and 8 b are used for engaging the hanging rope 9. Then, the leading end portion of the hanging rope 9 introduced from one through hole 8a is led out from the other through hole 8b and fastened on the grip portion 2.
[0009]
[Action]
Since the balance when the pump is suspended is determined by the positions of the engaging holes 8a and 8b in the grip portion 2, it is possible to completely prevent the pump from being tilted in an unexpected direction. The lowered pump can be raised and lowered stably.
[0010]
【The invention's effect】
According to the suspension structure of the portable submersible pump of the present invention, there is an advantage that the pump can be lifted and lowered safely and easily with a rope without requiring an eyebolt or the like for mooring a chain.
