JPS61196010A - Ship leaving and arriving device in pier - Google Patents

Abstract

PURPOSE:To decrease a departure and arrival expense and a time required for departure and arrival, by a method wherein the base end of a support plate which is expandable by means of oil pressure is pivotally secured in a horizontal pit, formed in the sea side of a pier, so that it can freely slew. CONSTITUTION:When a ship S comes alongside the pier, with a hydraulic pump 12 actuated, a piston rod 3 of a longitudinal hydraulic cylinder 4 is extended. The angle of the piston rod 3 is changed by operating the longitudinal cylinder 4 in the shape of a fan with the aid of a lateral hydraulic cylinder 8, and a beam is supported by means of rubber 5 of a support plate 6. The piston rod 3 is contracted as buffering is rendered effective with the progress of approach of the ship S, and the ship slowly comes alongside the pier.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to a departure and arrival device for a ship that can leave or berth with its own blade without the need for guidance from a tugboat or the like.

``Conventional technology'' Traditionally, when a ship departs from or arrives at a quay, the ship is moored to the quay and cannot change direction freely.
Particularly in the case of large ships, it was completely impossible for the ship to take off and land on its own. Therefore, in order to launch or land a ship, a large number of tugboats and other equipment were used to push the ship's belly and guide the ship separately, change direction, leave the berth, and berth.

``Problems to be Solved by the Invention'' However, this conventional method of taking off and landing requires the captain of a tugboat to be highly skilled, which increases the cost every time a ship takes off and lands. The drawback was that it took a considerable amount of time to ensure that the tugboats would not collide with each other even during a single landing.゛Means for Solving Problems'' The present invention aims to solve the above-mentioned problems.

At the landing and departure berth where ships come alongside, the base end of a hydraulically extendable support plate is pivotally attached in a horizontal hole pit provided on the sea surface side of the berth, allowing the ship to be pierced by other forces such as tugboats. To provide a device for launching and landing a ship at a quay, which is capable of taking off and landing at a quay with its own blade without having to borrow a ship, thereby reducing the cost of one launch and landing and the time required for launching and landing.

"Structure of the Invention" The present invention will be described below in detail based on illustrated embodiments.

Fig. 1 is a plan view of a ship launching and landing device at a quay according to the present invention, and Fig. 2 is a side view of the same. The base end of a vertical hydraulic cylinder 4, in which a piston rod 3 can be moved in and out, is pivotally mounted at the back of the horizontal hole pit 2. A receiving plate 6 having a rubber 5 fixed to its surface is movably pivoted to the tip of the piston rod 3. Further, a hook 7 for hanging a rope is provided on the upper part of the receiving plate 6. A horizontal hydraulic cylinder 8 is provided in the vicinity of the quay near the sea surface of the vertical hydraulic cylinder 4, and its base end is pivotally connected, and the tip of the piston rod 9 of the cylinder 8 is pivotally connected to the vertical hydraulic cylinder 4. Reference numeral 10.10 denotes a wheel, and the wheel 10.10 is provided near the front of the vertical hydraulic cylinder 4, and the rail t t , 1. I am supposed to be transferred to a higher rank. Each hydraulic cylinder 4.8 is operated by a hydraulic pump 12.

Several horizontal hole pits 2 in which the above-mentioned devices are installed are provided on the quay at predetermined intervals.

Note that the receiving plate 6 is
can operate forward, backward, left and right, but in addition to this, the ship S
The hydraulic cylinder may be moved up and down to suit the size of the object.

"Action of invention" Next, the operation of this invention will be explained.

When the ship S is about to berth, the hydraulic pump 12 is operated to extend the piston rod 3 of the vertical hydraulic cylinder 4, and the horizontal hydraulic cylinder 8 is moved while changing the amount of extension depending on the degree of inclination of the approaching ship S to the quay. As a result, the vertical hydraulic cylinders 4 are operated in a sector-like manner to change the angle of the piston rod 3, and the rubber 5 of each receiving plate 6 supports the hull of the ship reliably. Then, as the ship S approaches, the piston rod 3 is retracted while providing a buffer, and the ship slowly approaches the shore. In addition, when leaving the shore, the vertical hydraulic cylinder 4 moves the support plate 6, which supports the ship's torso with the rubber 5.
The piston rod 3 is pushed out by pushing the piston rod 3, and the amount and direction of the extension are changed to push the ship S toward the departure direction. The hook 7 engages a rope from the ship to ensure contact with the receiving plate 6.

``Effects of the Invention'' As described above, the present invention provides a system for swinging the base end of the receiving plate 6, which is extendable and retractable by hydraulic pressure, in the horizontal hole pit z provided on the sea surface side of the berth at the departure and arrival berth where ships dock. Since it is pivoted freely, the ship supported by the receiving plate 6 can be docked on the quay with its own blade without relying on other forces such as tugboats, and can leave and berth without relying on other forces such as tugboats. This has the effect of significantly reducing departure and arrival costs and departure and arrival times.
