Abstract

PURPOSE:To follow the variation of the draft and allow a quick separation of a pusher boat from a barge in an emergency by inserting a pin freely expanding/contracting by means of a hydraulic cylinder hole section vertically movable mounted on a post that is errected on a barge, from the broadside of a pusher boat. CONSTITUTION:A recessed section 2 that fits a pusher boat 10 is formed in the stern of a barge 1 and a post 3 is errected on the inside surface of the recessed section 2 and then a pin hole section 8 is provided so as to freely be moved vertically using a hydraulic cylinder mechanism 6 arranged in the post 3. A pin 15 capable of expanding/contracting using a hydraulic cylinder 17 is provided on the upper deck of a pusher boat 10 and inserted in the pin hole section 8. The variation of the draft line between the barge 1 and boat 10 can be absorbed in and followed by the hydraulic cylinder mechanism 7 inside the post 3. In an emergency, the pin 15 can be quickly withdrawn using the hydraulic cylinder mechanism 17 and both ships can be separated from each other immediately.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a coupling device between a purge boat and a pusher boat.

2. Description of the Related Art River-type purge vessels, which have been used in the United States and other countries, are gradually being used as ocean-going purge vessels in recent years. but,
There was a difficulty in the coupling mechanism between the purge boat and the purge boat, and there was no mechanism that could sufficiently respond to fluctuations in the water line of the purge boat and connect the purge boat and the purge boat with a simple mechanism yet firmly. Therefore, the applicant erected a pair of left and right guides in the concave part of the purge ship, installed the hydraulic cylinder downward, and fit the connecting fitting into the guide from the upper side of the pusher so that it could be guided vertically. We developed a connecting device that removably linked the lower end of the rod of a hydraulic cylinder with a bottle, and published a patent application No. 1 in 1980.
No. 55903).

Problems to be Solved by the Invention However, in the above-mentioned connecting device, the rod of the hydraulic cylinder on the purge ship side and the connecting fitting on the pusher side are connected with a pin, so that in the event of a disaster, the rod of the hydraulic cylinder on the purge ship side cannot be connected to the purge ship quickly. The drawback was that it was impossible to separate from the pusher.

Means for Solving the Problems In order to solve these problems, the present invention connects a seat with a pin hole to the lower end of the rod of a hydraulic cylinder in a post provided on the side of the purge vessel, and furthermore, a pusher A connecting pin is installed on the upper deck of the boat facing the strike plate so that it can be guided forward and backward using a hydraulic cylinder, and the coupling pin is fitted into the pin hole of the strike seat. It can fully respond to fluctuations in the water line, and in the event of an emergency, it can quickly release the connection and disconnect the purge boat and pusher boat.
It is characterized by being designed so that it can be separated and safety can be improved.

Hereinafter, the configuration of this Aoi Akira will be explained with reference to embodiment diagrams.

A support 3 is attached to the stern of the purge boat 1 by means of a mouth piece extending upward from the inner surface of the recess 2 provided for the pusher boat.
A hinge 5 is provided on the lower surface of the upper plate 4 of the support column 3 to pivot the push-down cylinder 6 downward, and a catch seat 8 is provided with a bottle hole 7 in the center position communicating from the front to the back. A twist 9 is provided on the top surface of the press-down cylinder 6.
A base plate 12 is installed on the upper deck 11 of the butcher boat 10, and a bottle hole is drilled in the side plate 13 whose gunwale protrudes upward, and a guide tube 14 is connected to the inner surface. A connecting pin 15 is fitted into the guide cylinder 14, a mounting bracket 16 is provided protruding from the rear upper surface of the base plate 12, an extrusion cylinder 17 is pivotally attached, and the tip of the rod 17' of the extrusion cylinder 17 is connected to the connecting pin 15. It is connected to the rear end with a hinge 18, and a connecting pin 15 is fitted into the pin hole 7 of the seat 8 of the support column 3.

action, effect Next, the effects of the present invention will be explained with reference to embodiment figures.

The coupling device according to the present invention has struts 3 erected at the front and back positions and the tip of the inner surface of a recessed portion 2 provided at the stern of a purge vessel 1, and a catch seat 8 that is moved up and down by a push-down cylinder 6 is fitted. let me,
A connecting pin 15 which can be fitted into the catch seat 8 is provided on the upper deck of the pusher boat 10 which is fitted into the recessed part 2 so as to be able to be moved back and forth by an extrusion cylinder 17.

After the pusher boat 10 is completely fitted into the concave portion 2 of the 4° purge boat 1, the bottle hole 7 of the catch seat 8 is adjusted by adjusting the length of the push-down cylinder 6 in the column 3 of the purge boat 1. The end of the connecting pin 15 of the pusher boat 10 is opposed to the tip, and then the end of the connecting pin 15 is fitted into the bottle hole 7 of the catch seat 8 while extending the rod 17' of the extrusion cylinder 17 of the pusher boat h10, and the purge boat is assembled. Even if the water line of barge 1, which connects 1 and Gnonyar Port IO at several points and navigates, changes due to cargo,
The rod 6' of the push-down cylinder 6 in each support column 3 can be freely adjusted with respect to the connecting pin 15 by expanding and contracting, and in the event that a purge boat IK danger occurs, each pusher boat 10 can be pushed out. The cylinders 17 are actuated at the same time to retract the connecting pin 15 from the catch seat 8, thereby quickly separating the pusher boat 10 from the sailboat 1 and improving safety during navigation. 0 that has various effects
