Title:
DISPLAYER FOR ATTITUDE OF EXCAVATION SHOVEL FOR PNEUMATIC CAISSON
Document Type and Number:
Japanese Patent JPH01165823
Kind Code:
A
Abstract:
PURPOSE:To permit unmanned operations in a pneumatic caisson by a method in which sensors are attached to each moving part of an excavating shovel, and on the basis of output signals of the sensors, the moving amounts of each moving part are calculated and displayed in image form. CONSTITUTION:Sensors 12, 13, 15, 16, and 17 are attached to the frame 3, rotary frame 5, first boom 7, second boom 9, and bucket 10 of an excavating shovel 1 for pneumatic caisson, by which the moving amounts of them are detected. On the basis of output signals S1-S5 of the sensors 12, 13, 15, 16, and 17, the attitude of each moving part is calculated in an attitude arithmetic unit 20, converted into image signals in a display arithmetic unit 21, and displayed on a displayer 22.
