Description

The present invention relates to an auxiliary tool for a hose to be attached to a curved portion bent in the middle of the hose.

Conventionally, water supply and drainage treatment using pipes has been performed in various fields such as civil engineering / equipment work and agriculture. In such water supply and drainage treatment, how to efficiently flow fluid including gas as well as liquid with low resistance when passing through the pipe is an important issue related to cost (energy cost, etc.) and working time. Met.

If the equipment related to water supply and drainage treatment is installed as permanent equipment, the best piping design will be done in advance even if it costs money. However, when the liquid in the tank is temporarily drained during maintenance of the water supply / drainage tank, for example, when a temporary temporary facility is used, an inexpensive and easy-to-use vinyl chloride hose is generally used. Water supply and drainage treatment is performed by the simple equipment that was used.

Due to the nature of the material, the vinyl chloride hose was soft and easy to bend. Therefore, when the liquid passes through the hose, it bends at a weak water pressure, and conversely, if the water pressure is strong, it cannot be bent at the place where it should be bent, and if it is forcibly bent, it breaks. Regardless of such a phenomenon, the hose is usually piped in a curved shape at a plurality of places.

At the location where the hose is bent, if the hose is bent beyond the permissible range, the hose is broken and the inside is crushed, which causes a disadvantage that the fluidity of the fluid flowing inside the hose is significantly reduced. Therefore, there is a problem that the work time of the water supply / drainage treatment is increased and the work efficiency is also lowered.

As a technique for solving such a problem caused by a broken or crushed hose, for example, as shown in Patent Document 1, a straight tube-shaped protector attached to the outer periphery of a curved hose has already been proposed. Such a protector is made of a straight pipe made of a flexible material, and has a plurality of notches substantially perpendicular to the length direction of the straight pipe, so that the protector is pushed into the outer circumference of a curved pipe hose while being inserted into a straight core rod. At that time, it was easy to bend along the shape of the curved tube hose and it was easy to install.

Japanese Unexamined Patent Publication No. 8-152095

However, in the case of the conventional technique described in Patent Document 1 described above, when the protector is attached to the outer circumference of the hose, the protector is inserted into one end of a separately prepared straight core rod, and the hose is forcibly inserted into this one end. There was a problem that it was necessary, a separate part was required, and the installation operation was troublesome.
Further, when a strong force is applied to the hose, the protector also bends together with the hose due to the notch, so that the inside of the hose may be crushed.

The present invention has been made by paying attention to the above-mentioned problems of the prior art, and can be easily and quickly attached to the curved portion of the hose due to the bending of the curved portion of the attached hose.

The engaging portion 31 extends so as to be elastically deformable from the outer peripheral side of the rib forming the outer shell of the upper cover half body 12, and the tip end 31a thereof is formed so as to protrude toward the inner peripheral side. By elastically deforming the engaging portion 31, the tip 31a gets over the rib at the end of the engaged portion 32 and engages with the engaged portion 32 by snap-fit from the direction intersecting the tubular axis direction. Further, on the rib extending at the center of the outer peripheral surface of the upper cover half body 12, projecting pieces 14 having small holes through which a fixing wire or the like is passed are provided at both ends and in the middle of the upper cover half body 12.

Next, the operation of the hose auxiliary tool 10 according to the present embodiment will be described.
In order to attach the hose auxiliary tool 10 to the curved portion A1 of the hose A, the cover halves 11 and 12 are brought close to each other from above and below with the curved portion A1 in between, and the positioning means 20 is used first to attach the hose auxiliary tool 10 to one side. A certain convex portion 21 is guided to a receiving portion 22 on the other side for positioning.

That is, with the curved portion A1 of the hose A placed on the inner peripheral side of the lower cover half body 11, the upper cover half body 12 is covered with the curved portion A1 and moved in the tubular axis direction to cover one end of the upper cover half body 12. The convex portion 21 on the side is guided to the receiving portion 22 on one end side of the lower cover half body 11. When the tip 21a of the convex portion 21 reaches the end of the inclined surface 22a of the receiving portion 22, it is positioned at that position without moving in any further direction.

With the convex portion 21 positioned on the receiving portion 22, the assembling means 30 then engages the engaging portion 31 on one side with the engaged portion 32 on the other side. That is, the other end side of the upper cover half body 12 is pressed against the other end side of the lower cover half body 11. Then, while the engaging portion 31 on the other end side of the upper cover half body 12 is elastically deformed, its tip 31a gets over the rib at the end of the engaged portion 32 on the lower cover half body 11 and is in the axial direction. It engages with the engaged portion 32 by snap fit from the direction intersecting with.

According to the positioning means 20, the cover halves 11 and 12 can be reliably positioned so as not to move with each other in one direction in the tubular axis direction by a simple configuration and operation. Further, according to the assembling means 30, it is possible to surely connect the cover halves 11 and 12 so as not to be easily disengaged in combination with the positioning by a simple configuration and operation.

Further, as shown in FIG. 10, since the outer peripheral surface of the lower cover half body 11 has a mounting means 40 for hooking on the upper end edge of the wall W on which the curved portion A1 of the hose A is placed, an auxiliary tool for the hose. The curved portion A1 of the hose A can be easily temporarily fixed via the 10 so as not to be displaced from the upper end edge of the wall W.

When the hose auxiliary tool 10 is attached to the curved portion A1 of the hose A, the rigidity of the hose auxiliary tool 10 regulates deformation such as bending of the curved portion A1 to a predetermined curvature or more, and inside the hose A. It is possible to prevent the flow space from being blocked. Therefore, the work efficiency of the water supply / drainage treatment in the piping route in which the hose A is partially curved can be improved, the work time can be shortened, and the cost can be reduced.

Further, since each of the cover halves 11 and 12 is formed in a semi-split cylinder shape in which a plurality of streaks intersect in a mesh shape, the weight can be reduced and the material cost can be reduced. In order to remove the hose auxiliary tool 10 from the hose A, the assembling means 30 may be disengaged by elastically deforming the cover halves 11 and 12 so as to widen the other ends. If both ends of the cover halves 11 and 12 are engaged with each other by snap-fitting, not only the configuration becomes complicated, but also the work of attaching / detaching the cover becomes troublesome.

Such an auxiliary tool 10 for a hose can be used for various water supply and drainage treatments, and is particularly suitable for water supply and drainage treatment as a temporary support by simple equipment. Specifically, for example, when the liquid in the tank is temporarily drained during maintenance of the water supply / drainage tank, when the drainage treatment is performed from the indoor equipment to the outside, when a large amount of liquid is supplied from the outdoor to the indoor equipment, or when the outdoor equipment is supplied. When the hose A is used as a simple facility, such as when water is supplied from one point to a plurality of points, it can be used for the curved portion A1 of the hose A.

As shown in FIG. 11, when it is desired to move a liquid such as water from a low point to a high point, a water absorption pump (not shown) is installed at the low point to suck up the liquid, and the liquid is sucked up at the point B through the hose A. Will be sent. At this time, when it is necessary to intentionally bend the hose A in the middle of arranging the hose A, if the curved portion A1 of the hose A is extremely bent and crushed, the flow rate decreases and the processing time becomes long. was there.

Therefore, by attaching the hose auxiliary tool 10 to the curved portion A1 of the hose A, it is possible to maintain an appropriate bending angle of the hose A. This makes it possible to avoid a decrease in concentration due to the need for unnecessary and appropriate monitoring of hose A and a decrease in labor productivity due to bending, and it is possible to eliminate the chronic labor shortage and labor for one individual. It is possible to promote the reduction of the burden, complete in time, meet the delivery date, reduce unnecessary accidents, and reduce the work cost.
