Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to underground continuous walls, water blocking walls, earth retaining walls, foundations of structures, and the like, and particularly to those places where space is limited such as underground, or narrow places such as various buildings. The present invention relates to an attitude control device of an underground continuous wall construction machine for performing an operation at the same time.

[0002]

2. Description of the Related Art A conventional attitude control device for an underground continuous wall construction machine is as shown in FIGS. That is, in the figure, reference numeral 10 denotes an excavation drive unit, reference numeral 20 denotes an operation unit, and the excavation drive unit 10 incorporates a not-shown sludge pump, a drive motor for the cutter 12, and the like, and corrects a shift in the excavation direction by a guide flap 11a. 11 and a drum-shaped cutter 12 arranged below the excavation drive unit 1.
Numeral 0 is suspended by a wire 22a via a pulley (not shown) provided at the tip of a tiltable boom 21b erected obliquely forward from the lower frame 21a of the main body 21 of the operation unit 20, and The wire 22a is wound around the drum of the winch 22.

[0003] The boom 21b has an adjust cylinder 21 connecting the upper part and the lower frame 21a.
By expanding and contracting c, it tilts back and forth, so that the excavation drive unit 10 moves in the height direction at the same time as the horizontal direction in the figure.

[0004] In the figure, reference numeral 23 denotes a horizontal hose drum wound with a sludge hose 23a for discharging sludge from a sludge pump (not shown), and 24 a vertical hose wound with a hydraulic / electrical wiring hose or the like. The operation unit 20 includes a crawler as shown in FIG. 1 and a rail 26 and wheels 27 as shown in FIG.
And so on.

[0005]

However, the attitude control device of the conventional underground continuous wall construction machine is one-way adjustment, and when the excavation drive unit 10 is moved in the left-right direction in the figure, the height direction also changes. In addition, since the adjustment range is narrow, the position of the operation unit 20 with respect to the underground continuous wall has to be relatively accurately positioned from the beginning. Further, since the horizontal hose drum 23 for the drainage hose 23a is provided on the ceiling of the operation unit 20, it is difficult to design the height to be low.

The present invention has been made in view of the above-described circumstances, and has an outer frame provided on an upper portion of an operation unit, and a boring drive unit is suspended at a tip end of the outer frame by a wire via a pulley.
It is an object of the present invention to provide an attitude control device of an underground continuous wall construction machine which solves the conventional disadvantages by moving the outer frame up and down and back and forth by a vertically moving cylinder and a forward and backward moving cylinder.

[0007]

In order to achieve the above object, an attitude control apparatus according to the present invention comprises an excavating drive unit having a drum-shaped cutter and an operating unit, and a excavating drive unit connected between the excavating drive unit and a wire or chain.

A hydraulic device for driving the two cylinders is provided, and the operation unit is mounted on a self-propelled device such as a crawler type or a rail type.

Further, the attitude control device of the present invention is configured such that an excavation drive unit having a drum-shaped cutter and an operation unit are separated, and the excavation drive unit can be lifted and lowered between both parts by a hanging tool such as a wire or a chain. In addition, in the underground continuous wall construction machine connected by flexible hoses such as a drainage hose and a power supply hose, and the hoisting device and the hose are wound up by a drum and fed out, a plate arranged above the operation unit is provided. The excavation drive unit can be moved up and down by wires through pulleys at the front of the outer frame, and is suspended horizontally.The front of the operation unit is pivotally attached to the outer frame and the lower frame, respectively.
