Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for mechanically performing rope pulling work and rope loosening work of mooring ropes of ships, especially large ships.

[0002]

[Prior art]

 At the time of berthing of the ship, as shown in FIG. 4, the ring-shaped tip of the mooring rope (mooring line) 19 dropped from the side of the ship 22 is picked up and pulled up to a predetermined mooring column 21 of the quay 20, and this is moored column. Tethering work to tie (hang) to 21 is performed. Further, when the ship leaves the shore, a net-releasing operation is performed in which the mooring ropes 19 are released from the mooring columns 21.

Conventionally, such rope-removing work and rope-releasing work have been performed manually.

[0004]

[Problems to be solved by the device]

 For this reason, it was necessary to mobilize a large number of workers for rope pulling and rope freeing of large ships such as cargo ships whose mooring ropes weigh several tons. In addition, the mobilized workers were not only required to perform a considerable amount of hard work, but were also extremely dangerous work that involved a fall accident into the sea.

[0005] Recently, in order to save labor in the rope-removing work, a dropped mooring rope has been pulled by a truck or the like and pulled up. However, there is an accident in which a pulling rope that connects the mooring rope and the truck is disconnected. There is still a problem in workability and safety because the truck itself is likely to occur and the weight of the mooring rope may pull it into the sea.

The present invention has been made in order to solve such a problem, and an object thereof is to provide a device capable of efficiently and safely performing rope-retrieval and rope-releasing work of a large ship with a very small number of personnel. And

[0007]

[Means for Solving the Problems]

 The rope catching and rope releasing device of the present invention which achieves the above-mentioned object is a mooring in which a toe space is expanded and contracted by a link mechanism 5 at the tip of the boom 3 of a construction vehicle 1 having a self-propelled traveling device 2 and an undulating boom 3. It is characterized in that a claw body 4 for gripping the rope is provided.

In this case, it is recommended that the self-propelled traveling device 2 is a wheel type and four-wheel drive.

[0009]

[Action]

 The device configured as described above can be freely moved on the quay by the self-propelled traveling device 2, and by combining the raising and lowering operation of the boom 3 from the driver's seat and the expansion / contraction operation of the pawls 4, the mooring rope is used. It is possible to freely perform operations such as lifting and lowering the mooring rope from a required position, or releasing the mooring rope that has been grasped.

[0010] Therefore, a series of rope-removing work such as moving to the dropping position of the mooring rope on the quay, pulling it up and pulling it up to a predetermined mooring column, and tying it up, and mooring ropes tied to the mooring column are performed. The rope-releasing work of grasping and releasing can be performed mechanically and safely by only one worker (driver).

Further, when the four-wheel drive is adopted for the self-propelled traveling device 2, slip is unlikely to occur during towing, and obstacles such as crane rails laid on the quay are easily overcome. In addition, the workability can be further improved by making it possible to move quickly and in a small turn.

【Example】

 FIG. 1 shows an example of a device embodying the present invention, in which 1 is a construction vehicle equipped with a self-propelled traveling device 2 and an undulating boom 3, and 4 is provided at the tip of the boom 3 via a link mechanism 5. It is a nail body that has been removed.

That is, the construction vehicle 1 is based on a power shovel, which is a type of excavator, and its traveling device 2 has wheels equipped with a mechanism that drives all four wheels from the original belt type. It has been changed to the expression one. A swivel base 6 is provided in the traveling device 2, and a vehicle body 9 including a driver's seat 7 and a driving power machine 8 is mounted on the swivel base 6. By driving the swivel base 6 from the driver's seat 7, the vehicle body 9 can be freely swiveled in both left and right directions by 360 °.

A hoisting boom 3 is attached to the swivel base 6. The up-and-down boom 3 is a main boom 3 having a shaft 10 mounted on an upper surface of a swivel base 6 so as to be vertically rotatable. ₁ And the main boom 3₁Sub-boom 3 with a shaft 11 attached to the upper end of the shaft so as to be rotatable in the vertical ₂ It consists of and. 12 is the main boom 3₁Hydraulic cylinder for ups and downs, 13 is a sub boom 3₂Is a hydraulic cylinder for undulation. Main boom 3₁And sub boom 3₂The operating angle of the hydraulic cylinders 12, 13 is controlled by operating the hydraulic cylinders 12, 13 from the driver's seat 7. As a result, the sub beam 3₂The tip position of the can be freely moved in the vertical direction or the front-back direction.

[0015] distal end portion of the sub-beam 3 _2, pawl member 4 having the structure between toe to scaling is attached by a link mechanism 5. As shown in FIGS. 2 and 3, this claw body 4 is composed of one lower claw 4 ₁ whose tip 4 ′ is bent upward and two upper claws 4 ₂ whose tip 4 ″ is bent downward. The lower claw 4 ₁ is fixed via a mounting plate 15 between the ends of the fixed rods 5a of the pair of link mechanisms 5, which are fixed to the opposite side surfaces of the auxiliary beam 3 _{2 by} a plurality of bolts 14, pawl 4 _2, the front and rear of the connecting rod 5b above the fixed rods 5a, between the tip of the rod 5c which is connected via a 5d, is mounted via a mounting plate 16.

[0016] Consolidated pin 17 between the rod 5b and the upper rod 5c of the rear, which is connected to the fixed rod 5a is operating rod 18 'of the hydraulic cylinder 18 disposed on the upper surface of the sub-beam 3 ₂ It is connected. The hydraulic cylinder 18 can be operated from the driver's seat 7. When the operating rod 18 'is expanded and contracted, the rod 5b of the link mechanism 5 swings back and forth, and with this movement, the tip portion of the rod 5c is moved. Makes a circular motion in the vertical direction. As a result, the gap L between the upper claws 4 ₂ provided at the tip of the rod 5c and the lower claw 4 ₁ provided at the tip of the fixed rod 5a can be freely expanded or contracted. The mooring rope 19 can be grasped and released.

The pawl member 4 having the above-described construction, by detaching the fixing bolt 14 of the fixing rods 5a, the sub-beam 3 can be removed from the ₂ easily, can replace the striking Chimento such as another excavator.

Further, the self-propelled traveling device 2 can be replaced with another traveling type such as a cover type if necessary.

[0019]

[Effect of device]

 As described above, since the device of the present invention has a structure in which the tip of a hoisting boom of a construction vehicle equipped with a self-propelled traveling device is provided with a claw body whose toes can freely expand and contract, it was dropped on the quay. A series of grabs the mooring rope, or straightens the hoisting boom to directly grab the mooring rope from the inside of the vessel, pulls it to the specified mooring column on the quay, and ties it up (hangs) on the mooring column. It is possible to mechanically perform the rope pulling work and the rope release work of picking up and releasing the mooring rope fixed to the mooring column.

Therefore, the number of personnel required for this type of work is only one driver, and the work can be performed safely and speedily.
