JPS5828019Y2 - Attitude control device for soil improvement processing machine - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an attitude control device for a soil improvement processing machine.

Conventional ground improvement equipment is shown in Figures 1 and 2.

That is, from the turret 2 erected on the hull 1, the ground improvement treatment machine 4
is suspended by a processing machine winch 5 so that it can be raised and lowered.

The processing machine 4 is held by a sub-reader 3 which can be moved up and down by a guide device 6 in the up and down direction.

Further, the sub-leader 3 is held by a guide device 7 that can be moved up and down the tower 2 (see FIG. 2).

In such a conventional device, it is difficult to correct the inclination caused by the penetration of the a-processor 4 into the ground.

(b) It is not possible to prevent an increase in the inclination angle due to the play required for raising and lowering the guide devices 6 and 7.

There were drawbacks such as.

Therefore, the purpose of this invention is to provide a device that controls the inclination of a processing machine that moves up and down, such as penetration and withdrawal. This allows the tilt of the machine to be controlled.

Embodiments of the present invention will be described in detail with reference to FIGS. 3 to 5.

Fig. 3 is a side view showing an embodiment of the attitude control device of the ground improvement device according to the present invention, and Figs. 4 and 5 are IV-IV in Fig. 3.
FIG.

This invention is a sub-noder 3 in the conventional ground improvement processing machine.
It is arranged in the guide device section between the and processing machine 4,
In Fig. 3, the upper part shows a link type movable guide device,
Reference numeral 8 indicates a four-link mechanism, and reference numeral 9 indicates a movement adjustment jack provided between the link connecting portions of the four-link mechanism 8.

A clamp 12, which is a slide movable guide, is attached to one end of the link 8, and the clamp 12 is held on a rail 13 of the sub-leader 3.

The lower part shows a telescopic movable guide device consisting of an inner and outer box.
The outer box is provided at the lower part of the sub-leader 3, and the inner box 10 is telescopically accommodated in the outer box, and is configured to extend and contract with respect to the sub-leader 3 by means of a horizontal movement adjustment jack 11.

A clamp 12 is attached to the tip of the inner box 10, and the clamp 12 is held on the rail 14 of the processing machine 4.

Although FIG. 3 shows a one-way control device, a right-angle control device may be added.

Each jack 9, 11 measures the inclination of the processor 4 or the hull 1 and its deviation from a predetermined reference position using an inclinometer, a displacement meter, an ultrasonic distance meter, or other means, and adjusts either one of them accordingly. , or both.

Two operating methods are selected as appropriate: a method in which the processor 4 is moved until it returns to the reference position, and a method in which a constant load is always applied to the guide portion.

Depending on the displacement and inclination of the processing machine 4 caused by various causes when the processing machine 4 penetrates and withdraws due to the vertical movement of the processing machine 4, either one or both of the movement amount adjustment jack 9 and the horizontal movement jack 11 is operated, and the sub-leader 3 or Force is transmitted to the processing machine 4 via the clamp 12, and the tilting of the processing machine 4 can be controlled.

In short, according to the present invention, the turret is vertically installed on the hull of the ship and is supported so that it can be raised and lowered via the sub-leader, and the stirring blade is attached to the bottom of the turret.
In a ground improvement treatment machine equipped with a digging blade, a movable sliding guide is slidably provided on the sub-leader or treatment machine, and between the guide and the sub-leader or treatment machine, the ground improvement treatment machine is moved in a horizontal plane according to the inclination displacement of the treatment machine or the hull. By providing a power operating means that operates in any direction, the inclination of the processing machine can be controlled and the operating rate of the processing machine can be improved.
