本発明は、シールドトンネルを築造するために使用する
機械のシールド掘進機の姿勢制御装置ｍ’に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an attitude control device m' for a shield excavator, which is a machine used to construct a shield tunnel.
（従来の技術）
シールド掘進機が機械式の場合には、掘進機本体の重心
位置は中央部より前部にあるため、このようなシールド
掘進機ではシールド本体が前傾し易く、その状態で掘進

の前部両側に、櫓状の姿勢制御板を突出固着させて姿勢
制御を行っている。(Prior art) When the shield tunneling machine is mechanical, the center of gravity of the machine body is located in the front part of the machine body. If the excavation continues, it will be difficult to construct a shield tunnel with a total length of 150,000 yen. For this reason, attitude control has conventionally been carried out by attaching oar-shaped attitude control plates protruding from both sides of the front side of the side bottom of the shell plate of the shield tunneling machine.

全破損させる問題点を有していた。(Problem to be Solved by the Invention) However, such a fixed attitude control plate can be used as a resistance plate when the shield tunneling machine needs to dig downward or horizontally. Not only does this interfere with its control and correction, but also when the shield excavation method is muddy water or earth pressure type, the shield (if the U wing is a closed type), it may cause damage to the inside of the vertical machine installed when the shield excavator is started. A gap was created between the entrance gasket and the shell plate of the shield tunneling machine, making it difficult to maintain normal mud water pressure and earth pressure, and the tunneling machine was propelled into the entrance gasket by the board. In some cases, the entrance gasket itself could be completely damaged.

The shell plate (2) is provided with an attitude control plate (5) having a surface that coincides with the surface of the shell plate (2), and the control plate (5) is set at an inclination angle with respect to the surface of the shell plate (2). Since the excavator (1) is adjustable and extends, it is possible to prevent the rolling of the excavator (1) by adjusting the projecting angle of the control plate (5) and to facilitate correction in the mi direction. This not only prevents unnecessary operation as a resistance plate, but also
It has the effect of preventing damage to the entrance buffkin when the shield gJ wing is completely sealed.
