Abstract

PURPOSE:To remodel simply the prior spud system to a carriage system by mounting a spud lifting mechanism mounting spud keeper on the aft hull through link pieces to move the spud keeper fore and aft with a horizontal movement mechanism. CONSTITUTION:A spud keeper 24 is mounted on an aft hull 20 through a plurality of upper and lower sets of link pieces 21a, 21b. On the upper portion of the spud kepper 24 is mounted a spud lifting and lowering mechanism to move vertically the spud. Between the spud keeper 24 and the hulL 20 is provided a horizontally expansible cylinder 36 which can move fore and aft the spud keeper 24 through the link pieces 21a, 21b. Thus, a carriage system of the spud keeper can be simply employed and remolded on the aft portion of the prior spud system dredger hull 20.

Description

[Detailed Description of the Invention] Kibenmei uses a pump-type dredger to suction and dredge sediment from the bottom of the water during mulberry cultivation! Komeno Dredger Subadoni I: 1 t-ridge involved.

In general, dredgers that excavate, suck up, and transport earth and sand from the bottom of the water are equipped with a spud supported by the rocky part of the hull, and the spud is driven into the bottom of the water, and the hull is rotated back and forth in a fan shape around this spud. , proceeding along the hull while revising the position where the spuds were inserted, the dredging was carried out one by one.
”: I’m trying.

Conventionally, there are two types of methods for using this spud to prevent the ship from advancing while hitting the spud with a stroke allowance of λ: the so-called spud method and the 1/tridgenote method.

The spud method is shown in Figures 1 and 2 (this hull 1).
Attach spud keepers 28 and 211 on both sides of the 19 end of tJ.
Eh, support 1 spud 3a and 3L+ for this respectively? Then, use gun 1-lie 11 and winch 5 to raise and lower spuds 3a and 3b. Then, make a suitable turn (t'! Directly insert the spud 31+ on the side '4J, then pull out the spud 3a on the right side of V'.
Turn it.

(Sequentially move the spuds 3a and 31+ to turn the hull 1!). Since the spud had to be replaced every time the fan-shaped movement in one direction was performed, the quality of the spud was extremely poor.

On the other hand, in the Kittredge method, as shown in FIG. 3, a well 6 is bored in the cut end of the hull '1, and the Kittredge table 7 is supported within this well 6 so that it can be moved backwards from IYJ.
You can see Spud Keeper 8 on this Kittredge trolley 7;
The kittridge stand skewer 7 is placed in the well 6 using the hydraulic cylinder 'IO' installed in the hull '1.
), each time the spud '11 is driven into the water bottom and the U-hull 1 is turned around it, the hydraulic cylinder 'I O+: moves the carriage carriage 7 to the hull '1'. Move it to the credit side, and use the reaction force to move the hull 1 forward! - (Dredging is carried out sequentially, and when the Kittridge cart 7 reaches the end of the 1st part of the 1st part 6, the auxiliary spud 12 is driven in, and the spud 1 of the carriage part 117 is dredged.
Raise 1 from the bottom of the water with a gentle V, Kittredge trolley 7
Well 6 Q) Move to the front and spud '11
The F111 primary dredging is performed in the same manner as described above by driving in the F111 spud 12 again.

This Kittredge method is advantageous in terms of the ability to create a second work, as the replacement work for Spud is smaller and less extensive than the aforementioned Spud/'j method).

But 17. Previously, there were 13 pump dredgers in our country.
The most popular spud system was (splash and /V).Therefore, in recent years there has been an increasing number of requests to change the spud system to the =l'+-ridge system. (The previous modified Z5 required a lot of work and cost a lot of money.)

So Kittredge lfM (unit 1 equipped with only +4)

Fi: 1 as a whole becomes longer, especially when dredging in a bay facing the outside, there are large differences in wave forces such as countercurrent and wind power, which makes it necessary to strengthen the winch for the anthorn. There were problems with stability, and the cost of constructing barges was high.

The present invention has been developed in view of the above-mentioned problems, and it is possible to simply change the spud type dredger of 1) to the Kittredge type dredger at a small cost, and when the dredger 11:) is newly built. The purpose of this project is to provide a dredger spud Killeridge that is easier to manufacture and costs less per unit cost than the conventional Killeridge method. Has a spud keeper,
