Description

  TECHNICAL FIELD The present invention relates to a swing control device for lifting an object and a method for suppressing a swing when lifting an object, which suppresses the movement of the wire when the object is lifted by a crane in water or on the water, sudden jumping, etc. Is.

  2. Description of the Related Art Conventionally, in the sea or the like, there is a case where an object is lifted using a crane (hoist) or the like in order to remove, move or collect the object. When lifting an object under the sea with a crane, although not shown, the object is provided in advance on a lifting hook attached to the tip of a lifting wire suspended from a crane mounted on a marine hoist ship. It was lifted by hanging a lifting ring.

  However, since the object to be lifted (hereinafter referred to as “the object to be suspended”) is in the sea, in the normal transparency of the sea, the lifting hook hooks the lifting ring or the like (hereinafter referred to as the “hanging state”). It is difficult to see from the sea. For this reason, there was a case where the suspended object was detached from the lifting hook for some reason and the crane was greatly shaken by the reaction, which was dangerous.

  In order to prevent such a situation, as a device for suppressing the swinging of the lifting hook, a device that is suppressed by connecting to a boom (arm-like structure) of a crane mounted on a hoist ship is known (Patent Document). 1). In addition, a method for measuring a shake and predicting and calculating a future shake is also known (see Patent Document 2).

  However, these methods can be expected to have a certain effect for a gentle, almost sinusoidal wave like a sea wave, but like a sudden detachment of a suspended object from a hanging hook. There was a problem that it was useless for a momentary vertical upward movement.

Furthermore, when a suspended object floating on the sea surface that is shaken by waves is lifted by a crane mounted on a hoisting ship that is also shaken by waves, the lifting hook is greatly shaken. In addition, since the floating suspended object is also greatly shaken, conventionally, a diver (diver) enters the sea and hooks the lifting hook on a lifting ring or the like (hereinafter referred to as “hanging work”). )), And then the lifting work was carried out, which was a dangerous work for divers and the work cost could not be ignored.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of an object suspension shaking suppression device 101 according to a first embodiment of the present invention.

  As shown in FIG. 1, the object lifting motion restraint device 101 is attached to the lifting wire 1, and the lifting wire 1 swings upward or downward in the lifting direction D <b> 1 or suddenly rises. It is a device for preventing exercise. Above the lifting wire 1 in FIG. 1, there is a crane (not shown) mounted on a marine hoist ship (not shown), and the lifting wire 1 is a boom of the crane (not shown). (Arm-like structure, not shown) suspended by a wire take-up device (or winch, not shown) of a crane (not shown) mounted on a hoist ship (not shown). Alternatively, the hoisting wire 1 is raised or lowered by being unwound to lift an object to be hung in the water.

  As shown in FIG. 1, the object suspension shaking suppression device 101 includes an underwater resistance member 2, a plurality (three in the case of FIG. 1) of the underwater resistance member attachment wires 3, and a plurality (of FIG. 1). In this case, the underwater resistance member mounting wire 3 'is provided below the three). In FIG. 1, reference numeral 4 is a lifting hook made of steel or the like attached to the lower end of the lifting wire 1.

  The underwater resistance member 2 is a plate-like member having a substantially circular planar shape, and is formed of a metal material, a synthetic resin material, or the like. A lifting wire first insertion hole 21 having a substantially circular cross-sectional shape is formed in a substantially central portion of the underwater resistance member 2. The underwater portion of the lifting wire 1 is inserted into the lifting wire first insertion hole 21 of the underwater resistance member 2. The underwater resistance member 2 is attached to the underwater portion of the lifting wire 1 by an underwater resistance member attachment wire 3, 3 ′, which will be described later, and is disposed in the water. Moreover, the underwater resistance member 2 has a surface (upper surface and lower surface) that is substantially perpendicular to the lifting direction D1 of the lifting wire 1, as shown in FIG.

  Examples of the metal-based material include metals such as steel and aluminum, alloys such as aluminum alloys, and fiber reinforced metal (FRM). Synthetic resin materials include plastics, fiber reinforced plastics (FRP), and the like. Among these, fiber reinforced plastics (FRP: Fiber Reinforced Plastics) include glass fiber reinforced plastics (GFRP), carbon fiber reinforced plastics, and the like. Alternatively, the underwater resistance member 2 is made of a sheet member made of a synthetic resin material, a cloth woven with a yarn made of a synthetic fiber, or a synthetic fiber so as to cover a framework formed of a metal material or a synthetic resin material. It may be a substantially plate-like member covered with the used nonwoven fabric.

  Further, a plurality (three in the case of FIG. 1) of the underwater resistance member mounting wires 3 are suspended from a first place P11 which is a place of a circumferential outer edge of the substantially circular plate-like underwater resistance member 2. It couple | bonds with the 2nd location P21 used as the position above the underwater resistance member 2 among the locations of the upper wire 1. FIG. In addition, a plurality (three in the case of FIG. 1) of the underwater resistance member mounting wires 3 ′ are provided at a first location P11 that is a location of a circumferential outer edge portion of the substantially circular plate-like underwater resistance member 2, and It couple | bonds with the 2nd location P22 used as the position below the underwater resistance member 2 among the locations of the lifting wire 1. FIG.

  With the configuration as described above, in FIG. 1, when an object under suspension (not shown) is to be lifted, the wire of a crane (not shown) mounted on a hoist ship (not shown) The hoisting wire 1 existing above FIG. 1 is taken up by a winding device (or winch, not shown). Thereby, the lifting wire 1 shown in FIG. 1 tends to rise upward in FIG.

  However, at this time, a substantially circular plate-like underwater resistance member 2 is attached to the lifting wire 1 so that its surface is substantially perpendicular to the lifting direction D1. For this reason, the underwater resistance member 2 receives resistance (hereinafter referred to as “underwater resistance”) from water. The value of the underwater resistance is approximately the product (V × A), where V is the value of the lifting speed of the lifting wire 1 and A is the surface area of the lifting wire 1 (for example, the upper surface). Proportional.

  Thus, in the state where the lifting wire 1 is rising and the underwater resistance member 2 receives resistance from water, the suspended object is detached from the lifting hook 4 for some reason, and the lifting wire 1 is rapidly raised. When attempting to do so, the wire ascending speed V of the underwater resistance member 2 (the value obtained by multiplying the proportional coefficient approximately V × A) rapidly increases, and the underwater resistance member. The underwater resistance value of No. 2 also increases abruptly, and the movement speed of the lifting wire 1 is suppressed to a very low speed. Therefore, the situation that a crane shakes greatly by the reaction of the movement of the hoisting wire which rises rapidly like the past does not arise.

  In addition, according to the object lifting motion restraint device 101, the lifting hook 4 at the lower end of the lifting wire 1 swings upward or downward in the lifting direction D1, or makes a sudden upward movement. Can also be prevented.

  If the underwater resistance member 2 is made of a transparent material, for example, transparent plastics, a steel frame with a transparent vinyl sheet attached, etc., the visibility from the sea is improved, and the accident prevention function is further improved. Can be increased.

  Further, a plurality of the above-mentioned underwater resistance members 2 may be installed so as to form a plurality of steps in the vertical vertical direction of the lifting wire 1. When the area value of one underwater resistance member 2 is appropriately set and the number (stage number) of the underwater resistance members is appropriately set, the underwater resistance force can be adjusted to an appropriate value.

  Moreover, you may make it provide the notch part (recessed part) of a hole and an outer edge part in the main body (plate-shaped part) of said underwater resistance member 2 suitably. If the number or area value of the holes or notches or the cross-sectional shape is appropriately set, the resistance in water can be adjusted to an appropriate value.

  Moreover, you may make it attach one or more parachute-like members to the upper surface or lower surface or both surfaces of the main body (plate-shaped part) of said underwater resistance member 2 suitably. If the number, area value, or cross-sectional shape of the parachute-like member is appropriately set, the underwater resistance can be adjusted to an appropriate value.

  FIG. 2 is a view showing a configuration of a variation example of the object suspension shaking suppression apparatus according to the first embodiment of the present invention, and FIG. 2A is a diagram illustrating the object suspension according to the first embodiment of the present invention. FIG. 2 (B) shows the configuration of the first variation example of the vibration suppression device, FIG. 2 (B) shows the configuration of the second variation example of the object suspension vibration suppression device according to the first embodiment of the present invention, and FIG. The structure of the 3rd modification of the shaking suppression apparatus at the time of object suspension which is 1st Example of invention is each shown.

  In FIG. 2A, the underwater resistance member 2A is a plate-like member having a curved surface that protrudes downward. Other configurations, that is, the attachment positions of the lifting wire first insertion hole 21A, the underwater resistance member attaching wires 3 and 3 'having a substantially circular cross-sectional shape, and the like are the same as those of the underwater resistance member 2 in FIG. In this underwater resistance member 2A, the projected area on the projection plane substantially parallel to the lifting direction D1 of the lifting wire 1 (that is, the projected area when viewed from a direction substantially perpendicular to the lifting direction D1 of the lifting wire 1). Hereinafter, “vertical projected area” is not zero (in the case of the underwater resistance member 2 in FIG. 1, since it is a substantially flat surface, the vertical projected area is almost zero). By setting this vertical projection area value to a value larger than a certain value (hereinafter referred to as “first area value”), a direction (hereinafter referred to as “substantially perpendicular” to the lifting direction D1 of the lifting wire 1). , "Wire vertical direction"), or a sudden movement is prevented. When the diver (diver) is in the water in the vicinity of the lifting wire 1 when the lifting wire 1 is lifted, in the object lifting motion suppression device 101 in FIG. However, there is a risk that the underwater resistance member 2 may move in a substantially horizontal direction or obliquely upward and collide with a diver. However, in the object suspension control apparatus of FIG. Since the underwater resistance force in the vertical direction of the wire also acts, the moving speed in the vertical direction of the wire is suppressed to a low speed. As a result, in the object suspension shaking suppression device having the configuration shown in FIG. 2A, an accident such as a collision with a diver can be prevented.

  In FIG. 2B, the underwater resistance member 2B is a plate-like member having a curved surface that protrudes upward. Other configurations, that is, the attachment positions of the first lifting wire 21B having a substantially circular cross-sectional shape, the underwater resistance member attachment wires 3 and 3 ', and the like are the same as those of the underwater resistance member 2 in FIG. In this underwater resistance member 2B, the projection area on the projection plane substantially parallel to the lifting direction D1 of the lifting wire 1 (that is, the projected area when viewed from a direction substantially perpendicular to the lifting direction D1 of the lifting wire 1). (Vertical projection area) is not zero. By setting the vertical projection area value to a value larger than a certain value (hereinafter referred to as “first area value”), the vertical projection area is substantially perpendicular to the lifting direction D1 of the lifting wire 1. Shaking in the vertical direction of the wire or sudden movement is prevented. When the diver (diver) is in the water in the vicinity of the lifting wire 1 when the lifting wire 1 is lifted, in the object lifting motion suppression device 101 in FIG. However, there is a risk of the underwater resistance member 2 moving in a zigzag shape substantially horizontally or obliquely upward and colliding with a diver. Since the underwater resistance force in the vertical direction of the wire also acts, the moving speed in the vertical direction of the wire is suppressed to a low speed. Thus, in the object suspension fluctuation suppressing device having the configuration shown in FIG. 2B, an accident such as a collision with a diver can be prevented.

  The configuration in FIG. 2C is the same as that in which both the underwater resistance member in FIG. 2A and the underwater resistance member in FIG. 2B are attached to the lifting wire 1. That is, the underwater resistance member 2C1 is a plate-like member having a curved surface that protrudes downward. The underwater resistance member 2C2 is a plate-like member having a curved surface that protrudes upward. The other configurations, that is, the mounting positions of the lifting wire first insertion holes 21C1 and 21C2 and the underwater resistance member mounting wires 3 and 3 ′ having a substantially circular cross-sectional shape are the same as in the case of the underwater resistance member 2 of FIG. is there. In these underwater resistance members 2C1 and 2C2, the projected area on the projection plane substantially parallel to the lifting direction D1 of the lifting wire 1 (that is, when viewed from a direction substantially perpendicular to the lifting direction D1 of the lifting wire 1). The projection area (vertical projection area) is not zero. By setting the value of the vertical projection area to a value larger than a certain value (hereinafter referred to as “first area value”), it is a direction that is substantially perpendicular to the lifting direction D1 of the lifting wire 1. Shaking in the vertical direction of the wire or sudden movement is prevented. When the diver (diver) is in the water in the vicinity of the lifting wire 1 when the lifting wire 1 is lifted, in the object lifting motion suppression device 101 in FIG. However, there is a risk of the underwater resistance member 2 moving in a zigzag shape in a substantially horizontal direction or obliquely upward and colliding with a diver. Since the underwater resistance force in the vertical direction of the wire also acts, the moving speed in the vertical direction of the wire is suppressed to a low speed. Thus, in the object suspension shaking suppression device having the configuration of FIG. 2C, an accident such as a collision with a diver can be prevented.

  As described above, in the object suspension fluctuation suppressing device 101 according to the first embodiment of the present invention, the structure is simple, and a sensor or the like for detecting a sudden fluctuation of the suspension hook 4 is not required. In addition, there is an advantage that a power device for driving other members or the like is not required so as to suppress a sudden fluctuation of the lifting wire 1 and that the attaching / detaching work to the lifting wire 1 is easy. It is correct.

  Hereinafter, an object suspension fluctuation suppressing apparatus 102 according to a second embodiment of the present invention will be described in detail with reference to FIG.

  As shown in FIG. 3, the object suspension fluctuation suppressing device 102 can float on the sea surface while being inserted into the suspension wire 11, and is suspended on the sea surface that is shaken by waves.

The lifting hook 14 at the lower end of the lifting wire 11 can be moved substantially in the vicinity of the suspended object (not shown) by pulling it near the object (not shown). In addition, the movement of the lifting hook 14 (being shaken) can be substantially interlocked with the movement of the suspended object (not shown, also being shaken) on the water surface. Thereby, there exists an effect that it becomes easy to hook the lifting hook 14 on the suspended object on the water surface.

  Further, a holding / moving member 16 having a substantially disk shape (a diameter value of the disk is a wire) is provided at a position of the lifting wire 11 (a position below the wire insertion member 12) which is an upper position of the lifting hook 14.
