Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo-handling hose lifting device for hoisting a cargo-handling hose connecting a floating oil storage tank and quay-side cargo handling equipment using a counterweight.

As shown in FIG. 1, a floating oil storage tank 1 moored offshore of a quay 4 is connected to a cargo handling equipment (not shown) on the quay 4 side by a cargo handling hose 2.

In order to prevent the cargo-handling hose 2 from being bent excessively, the middle part of the cargo-handling hose 2 is conventionally held in a saddle 3, and one end of the suspension rope 12 is connected to the saddle 3 via a saddle-hanging hook 13. is locked. Furthermore, this suspension rope 12
is guided by pulleys 10° 11 of a pedestal 5 provided on the storage wall 4, and a counterweight 9 is locked to the other end of this hanging rope 12 hanging downward, so that the cargo handling hose 2 is lifted up. It is being

Note that a saddle guide pin 20 is attached to the saddle 3, and this guide pin 20 is guided by a saddle up and down guide 14 formed on the pedestal 5, so that it can move up and down.

Therefore, even if the floating oil storage tank 1 moves up and down due to tides, loading conditions, waves, etc., the cargo handling hose 2 is moved appropriately by the counterweight 9 via the saddle 3 at the end of this movement, and the cargo handling hose 2 is This prevents bending.

In FIG. 1, the reference numeral 6 indicates the quay side manifold r17, the oil storage tank side manifold, and 8 indicates the sea level.

By the way, in such a cargo-handling hose lifting device, the center of gravity of the cargo-handling hose 2 moves as the floating oil storage tank 1 moves, and the force acting on the suspension rope 12 fluctuates.

In other words, as shown by the solid line in FIG. 1, when the floating oil storage tank 1 is at the lowest position, the force acting on the suspension rope 12 is the largest; ,
When the floating oil storage tank 1 is at the highest position, the suspension line 1
The force acting on 2 is the smallest.

Since the weight of the counterweight 9 is constant in the conventional cargo-handling hose hoisting device as shown in Fig. ttSi, it cannot cope with the above-mentioned change in the force acting on the hanging rope 12 (tJ)J, and therefore the cargo-handling hose cannot be lifted. There is a problem that it cannot be hung properly.

The present invention aims to solve these problems, and an object of the present invention is to provide a cargo-handling hose hoisting device that can adjust the weight of the counterweight in accordance with fluctuations in the force acting on the hanging rope. shall be.

Therefore, the cargo handling hose hoisting device of the present invention includes a suspension rope that has one end anchored to the intermediate portion of the cargo handling hose that connects the floating oil storage tank and the quay side cargo handling equipment, a pulley that guides the suspension rope, and a pulley that guides the suspension rope. and a counterweight that is latched to the other end of the suspension rope hanging downward via the pulley, and is attached by engaging with the counterweight as the counterweight rises. A preliminary counterweight is placed on the weight support portion of the pedestal so as to be passed through the suspension rope once.

Hereinafter, a cargo handling hose lifting device as an embodiment of the present invention will be explained with reference to the drawings. FIG. 2 is a side view thereof;
FIG. 3 is an enlarged perspective view showing the counterweight and the preliminary counterweight, and in the figure, the same reference numerals as in FIG. 1 indicate almost the same parts.

As shown in FIG. 2, the floating oil storage tank 1 moored offshore of the quay 4 is connected to cargo handling equipment (not shown) on the quay 4 side by a cargo handling hose 2.

The middle part of the cargo handling hose 2 is held in a saddle 3, and one end of a suspension rope 12 is secured to the saddle 3 via a saddle lifting hook 13, and the suspension rope 12 is connected to a pulley of a pedestal 5 provided on a quay 4. You will be directed to 10.11.

A counterweight 17 is fixed to the other end of the hanging rope 12 hanging downward, and as the counterweight 17 rises, a plurality of (two in this embodiment) spare counters are added to the counterweight 17. (way) 15 and 16 are placed on the weight support parts i s and i 9 on the sides of the pedestal 5, respectively.

Furthermore, as shown in Figure 3, a preliminary counterway)
A hanging rope passing hole 21 is formed in 15 and 16, and the hanging rope 12 is inserted into this hanging rope passing hole 21, and the counterweight 17 is moved as the counterweight 17 rises.
16 and become one body, and when further raised, the preliminary counterweight 16 engages with the preliminary counterweight 15.

Note that a counterweight 17. is attached to the weight support portions 18.19. An aperture is formed to allow a preliminary counterweight 113.15 to pass through.

Further, in this embodiment, there are two spare counterweights, and as the counterweight 17 rises, a heavier spare counterweight is added. The weight and placement position can be selected appropriately.

Since the cargo handling hose lifting device of the present invention is configured as described above, when the counterweight 17 is raised, the preliminary counterweight 16 is first added to the counterweight 17, and then the preliminary counterweight 1 is added to the counterweight 17.
5 is added.

Conversely, when the counterweight 17 and the spare counterweight 16.15 are lowered from the state where they are engaged and integrated, the spare counterweight 15 first
is placed on the weight support section 18, and a preliminary counterweight 16 is placed on the weight support section 19.

Therefore, even if the floating oil storage tank 1 moves up and down due to tides, loading conditions, waves, etc., the cargo handling hose 2 will move up and down appropriately due to this up and down movement, and extreme bending of the cargo hose 2 will be prevented. , the counterweight 17 and the reserve counterweight depending on the force acting on the sling 12 which varies depending on the position of the floating tank 1) 16.
The weight according to 15 is adjusted.

That is, when the floating oil storage tank 1 is at the lowest position (solid line in FIG. 2) and the greatest force is applied to the suspension line 12, the counterweight 17 and the reserve counterweight)
16 and 15 are engaged and become one body, and the weight acting on the other end of the suspension rope 12 is the heaviest. On the other hand, floating oil storage tank 1
is at the highest position (imaginary line in FIG. 2) and the smallest force acts on the suspension rope 12, only the counterweight 17 is locked to the other end of the suspension rope 12, and this suspension rope The weight acting on the other end of 12 is the lightest.

As detailed above, according to the cargo-handling hose hoisting device of the present invention, the sling rope has one end anchored to the intermediate portion of the cargo-handling hose that connects the floating oil storage tank and the quay-side cargo handling equipment, and A guide pulley, a pedestal for supporting the pulley, and a counterweight that is latched to the other end of the suspension rope hanging downward via the pulley, and as the counterweight rises, the counterweight is suspended. It has a simple structure in which a spare counterweight that is added by engaging with the weight is inserted through the suspension rope and placed on the weight support part of the mount, and the counterweight is attached as the floating oil storage tank moves up and down. The weight of the counterweight is automatically adjusted in accordance with the varying force acting on the hanging rope, which has the advantage that the cargo hose can be suspended appropriately.
