Position detection device and method for detecting position of excavator bucket

ANDERSEN KASPAR HARTWIG

A position detection device (2) for detecting a position of a bucket (4) of an excavator (6) having a cab (32) and one or more boom arms (8) is disclosed. The excavator (6) comprises a first boom (8) rotatably attached to the cab (32) by a mounting structure (12) rotatably attached to the cab (32) by a shaft (14) having a longitudinal axis (X) extending substantially vertically during normal use of the excavator (6). The bucket (4) is rotatably mounted to an arm (24) that is rotatably attached to a first boom (8) or to a second boom that is rotatably attached to the first boom (8). The cab (32) has a longitudinal axis (Y) and a transverse axis (X) extending perpendicular to the longitudinal axis. The mounting structure (12) is arranged and configured to allow rotation of the first boom (8) relative to the longitudinal axis (Z) of the shaft (14). The position detection device (2) comprises one or more antennas (20) arranged and configured to receive satellite signals from one or more satellites. The position detection device (2) comprises a sensor assembly (10) configured to detect an angular position (alpha) of the first boom (8) relative to a rotation about a longitudinal axis (Z) of the shaft (14).

公开了一种用于检测挖掘机(6)的铲斗(4)的位置的位置检测装置(2)，挖掘机具有驾驶室(32)和一个或多个动臂(8)。挖掘机(6)包括通过安装结构(12)可旋转地附接到驾驶室(32)的第一动臂(8)，该安装结构通过轴(14)可旋转地附接到驾驶室(32)，该轴具有在挖掘机(6)的正常使用期间基本上竖直延伸的纵向轴线(X)。铲斗(4)可旋转地安装到斗杆(24)，所述斗杆(24)可旋转地附接到第一动臂(8)或第二动臂，第二动臂可旋转地附接到第一动臂(8)。驾驶室(32)具有纵向轴线(Y)和垂直于纵向轴线延伸的横向轴线(X)。安装结构(12)被布置和构造成允许第一动臂(8)相对于轴(14)的纵向轴线(Z)旋转。位置检测装置(2)包括被布置和配置为从一个或多个卫星接收卫星信号的一个或多个天线(20)。位置检测装置(2)包括传感器组件(10)，传感器组件被配置为检测第一动臂(8)相对于围绕轴(14)的纵向轴线(Z)的旋转的角位置(α)。
