An enlarged cross-sectional view of an embodiment of the float for the unloading hose according to the present invention.

The present invention relates to a pullout for an unloading hose used to connect a pipeline laid on the seabed to a marine hose connected to a vessel.

This type of float is typically fitted to the hoses constituting the hose line so that the buoys connected to the marine hoses and the unloading hose lines connecting the pipelines can flexibly respond without buckling, even if they receive waves. Catenary line is forming.

Floats of the above kind consist of two semi-annular hard floaters, each having a flotation material therein. The two returnable floats have protrusions and recesses hinged through the pins at one end thereof, and the tartan has a rectangular notch facing each other and spread through the pins. Around one of these pins is fitted a bearing member, which is connected to the other pin via a turtle butt, which is fixed to the other pin. The turnbuckle acts to keep the pins close to each other.

These conventional floats for unloading hoses have the drawback that not only the pins bend after years of use, but also the floats are released from the unloading hoses by opening the hull.

Numerous efforts have been made to address these shortcomings, but no one has produced satisfactory results. Accordingly, it is an object of the present invention to provide a float for unloading hose that can eliminate the above-mentioned drawbacks encountered in the prior art.

A feature of the present invention is that a pair of return hard supports, extending through one end of each return support, pins constituting a hinge that the return support is above, the other end of the return support One fixed female thread member in the notch, the other notch being formed by a pair of opposing notches formed in and extending through one of the notches, the pin having a width substantially equal to the width of one of the notches. Extending through and having a hook-shaped member for engaging with a pin having a width substantially equal to the width of the other notch, and a threaded portion opposed to each end of the apex, the bolt being screwed with the female screw member and the hump-shaped member; The end of the bolt is configured to prevent the pin from deviating from the black member when the bolt is secured to fit the float around the unloading hose. To provide a float for loading hoses group hump protruding into the shaped member.

Other objects and features of the present invention will be fully understood from the following detailed description with reference to the accompanying drawings.

FIG. 1 is a conventional float for unloading hose, each consisting of a set of return-phase hard supports a, b containing a flotation material therein. The buoys a, b have recesses and protrusions engaging their one ends a, b ₁ and are hinged to each other by pins p extending through the recesses and protrusions.

The buoys a, b are opposed to their other ends a ₂ , b _2, and have a rectangular notch c, d extending through the pins e, f respectively. Around one of the pins, for example, the pin e is fitted to the bearing member g connected to the hook i via the tunnel buckle h. The hook i engages with the other pin f.

The turnbuckle h pushes pin e so that these pins are close to each other. As a result, years of use not only bend pin e, but also hook i. So there is a risk that the float will deviate from the lowering hose.

The present invention provides a float for the unloading hose that can eliminate the above-mentioned drawbacks.

2 shows one embodiment of a float for the unloading hose. In Figure 2, reference numerals 1 and 2 refer to the hard flotation on return.

In return, the buoys 1, 2 have recesses 3 and 4 protrusions at one end thereof. This recess 3 and the protrusion 4 engage each other and have a cavity hole extending through the pin 5. Pin 5 mates with nut 6,6 at its end, respectively, and returning body 1, 2 is engaged with the hinge at its first end.

In return the buoys 1, 2 have rectangular notches 7,8 opposite each other. These notches 7,8 extend through pins 9,10, respectively, and they join nuts 11,12 at their respective ends.

For example, one of the pins 9 and 10 has a U-shaped member 13a having a width substantially the same as the width of the notch 7 in the pin 9 and opening toward the notch 8, and located on the notch 8 side other than the member 13a. The female screw member 13 constituted by the face plate 13c having the tapped holes 13b is engaged.

A hook-shaped member 14 having a width equivalent to the tip of the notch 8 is engaged with the pin 10. The hook-shaped member 14 is provided with the tab hole 14b in the outside, and is comprised from the face plate 14c and the hook part 14a arrange | positioned at the part of the hook part 14a which opposes the notch 7. As shown in FIG.

The tab holes 13b and 14b have threaded portions that are inclined oppositely.

In FIG. 2, reference numeral 15 denotes a bolt with threaded portions 15a, 15b inclined opposite its ends.

As shown in FIG. 3A, the threaded portions 15a, 15b of the bolt 15 are engaged with the tab holes 13b, 14b of the face plates 13c, 14c of the hook-shaped member 14 and the female screw member 13 simultaneously.

When the float is fitted around the unloading hose (not shown), it is moved into the female screw member 13 and the hook-shaped member 14 until the opposing cross-sections of the support bodies 1 and 2 come into contact with each other as shown in Fig. 3B. Reference numeral 16 designates a lock nut that holds the bolt 15 in its tightening position.

As shown in FIG. 3B, at the tightening position of the bolt 15, the cross section of the bolt 15 is in contact with the pin 10 or close to the pin 10, thereby preventing the pin 10 from being separated from the hook-shaped member 14 through the opening 14d.

In addition, the use of the U-shaped member 13a having a sufficiently long longitudinal direction allows the cross section of the bolt 15 disposed on the female screw member 13 to be moved without restricting the tightening action of the bolt 15.

The float for the unloading hose manufactured as described in accordance with the present invention is stressed because the force in the tensioning direction of the bolt 15 is distributed over the entire notched length of the pins 9 and 10 by the wide female thread member 13 and the hook 14 together. Deformation of the pins 9 and 10 due to concentration and the hook part of the hook is advantageously prevented, and even when the hook 14d is deformed in the direction in which the opening 14d of the hook 14 increases due to prolonged use, the cross section of the bolt protruding into the hook contacts the pin 10. Even if the hook opening 14d is located in the vicinity thereof and the deformation of the hook opening 14d increases, the cross section of the bolt protruding into the hook contacts the pin 10, and the hook opening 14d is positioned in the vicinity so that the hook opening 14d is substantially bent. Departure from 14d is prevented.

4a and 4b show another embodiment of a float according to the invention. In this embodiment, when the pin 15 is fixed so as to sandwich the float around the unloading hose (not shown), the front and rear ends of the oppositely inclined threads 15a and 15b of the bolt 15 are lower than the pins 9 and 10 as shown in Fig. 4b. Bolts 15 are arranged to contact with.

In the present embodiment, the tab holes 13b and 14b of the hook-shaped member 14 and the female screw member 13 are formed such that the bolt 15 does not contact the female screw member 13 and the hook-shaped member 14.

In the embodiments of FIGS. 4a, 4b and 5a, 5b, a long bolt 15 can be used regardless of the size of the float for the unloading hose.

As described above, the floating hose float not only effectively prevents deformation of the pins 9, 10 and the hook-shaped member 14, but also prevents the pin 10 from being detached from the hook-shaped member 14.
