Abstract

PURPOSE:To freely operate a connecting section from the upper deck by forming recessed sections on the upper-deck section and bottom section of a pedestal ship, providing a pin section on one bottom recessed section of the pedestal ship and a hook section on the other bottom recessed section of the pedestal ship, and arranging a rotary operating member of the hook section in the upper deck recessed section CONSTITUTION:Water-tight recessed sections 6a, 6b are formed on the bottom section of a pedestal ship 7, a pin 15 is provided in one water-tight recessed section 6b and a hook 11 is provided in the other water-tight recessed section 6a. A recessed section 8 is formed on the corresponding upper deck section of the pedestal ship 7 provided with the hook 11, both recessed sections 8, 6a are connected with a tube section 9, a shaft 10 is arranged in the tube section 9 so that the rotary operation of the hook 11 can be freely driven by a rotary operating section 12 arranged in the recessed section 8 via the shaft 10, Accordingly, the hook pin connecting section below the draft line can be simply operated from the upper deck.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a coupling device for an assembly barge.

Conventional technology Traditionally, in the construction work of beaches, river banks, etc., small barges were connected using concave and convex joints or pin joints to assemble the barges.
Working machines such as hydraulic shovels and crenins are installed on the barge. However, when joints are made using a concave-convex joint or a pin joint, there is a gap between the barges, so the barges tend to swing independently due to the load. Therefore, a connection mechanism has been developed in which the sides of each barge are brought into close contact with each other and connected using bolts and nuts.

Problems to be Solved by the Invention However, when bolting the sides of each barge, a worker must enter the barge and fit it into the bolt hole of the opposing barge to make the joint. It had the drawback of requiring time and effort.

In order to solve these problems, the present invention is characterized in that the bottom of the joint part of the work barge can be easily connected from the upper surface of the deck using hooks and pins.

A foolproof way to solve problems Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

In an assembled barge that connects box-shaped barges to each other,
A long hole 3a is formed in the lower end of the joint plate 2a of one barge 1a, and a side plate 5a is provided around the inner surface of the long hole 3a with upper and lower reinforcing plates 4a and 4'a facing each other. A hook chamber 6a is provided, and a recess 8 is provided in the upper deck 7 facing one half-rested portion of the hook chamber 6a, and the center of the inner bottom surface of the recess 8 and the upper and lower reinforcing plates 4a are provided.
, 4/a, and a shaft pipe 9 is connected to the shaft hole of the upper reinforcing plate 4a and the recess 8, and an operating shaft 10 is connected to the shaft pipe 9.
is inserted and its lower end is pivotally supported in the shaft hole of the lower reinforcing plate 4'a, and the hook 11 is fixed to the operating shaft 10 in the hook chamber a. Fix the disc 12 and engage the handle at the front and rear positions of the disc 12 $1
3.13' is drilled and an engaging groove 13 is formed on one inner surface of the recess 8.
A lock groove 14 that communicates with the long hole 3a of the other barge 1b is provided at the lower end of the joint plate 2b of the other barge 1b.
A long hole 3b in the middle is opened, and a watertight pin chamber 6b is provided on the inner surface of the long hole 3b with upper and lower reinforcing plates 4b, 4'b facing each other and a side plate 5b surrounding the pin chamber 6b. The vertical pin 15 with which the hook 11 engages is attached to the upper and lower reinforcing plates 4b, 4.
'b. In addition, 16 in the figure
17 is a handle, 17 is a donut plate, 18.18' is an engaging protrusion, and 19 is a lid plate.

Functions and Effects The coupling device according to the present invention has a hook chamber 6a and a pin chamber 6b facing each other at the sides, bow, stern, etc. of the barge 1a and the barge 1b.
The joint plate 2a and the joint plate 2b on the outer surface of the barge 1a and the barge 1b are joined to form a joint plate 2a +
When the bolt hole at the upper end of 2b is connected with a bolt nut, the hook chamber 6a and the pin chamber 6b are automatically connected, and as shown in FIG.
The retaining protrusions 18 and 18' protruding from the lower surface of the donut plate 17 at the tip end of the handle 16 as shown in FIG. While rotating the operating shaft 10 with 16, the hook chamber a
The inner hook 11 is inserted into the opposing bottle chamber 6b, and the hook 11 is engaged with the vertical pin 15 to be linked, and then,
After the handle 16 is removed from the disc 12, a locking block piece is fitted into the locking groove 14 in the recess 8 and the engaging groove 13 of the disc 12 opposite to it. Therefore, by installing the coupling device according to the present invention at a position below the water line of the barge, the assembled barge can be connected extremely easily and its strength can be increased, and the above-mentioned remarkable effects can be achieved. It is.
