Abstract

When an object detected by a distance measuring sensor is located in a monitoring region set in a blind spot of an operator, an obstacle determination section determines the detected object as an obstacle. Then, the obstacle determination section sets a monitoring region so that a region indicating a lower travelling body (2) is excluded according to a slewing angle detected by an angle sensor. Based on the slewing angle detected by the angle sensor, a stop control section determines a component, of at least one of the lower travelling body and an upper slewing body, which has a possibility that a construction machine collides with the obstacle when the component is operated, and stops operation of the determined component.

Claims9

Dependent claims

An obstacle detection device for a construction machine including a lower travelling body and an upper slewing body pivotally mounted on an upper portion of the lower travelling body, comprising:

an object detection unit provided on the upper slewing body and for detecting a three-dimensional position of an object located around the construction machine;
an angle detection unit for detecting a slewing angle of the upper slewing body with respect to the lower travelling body;
and
an obstacle determination section for setting a monitoring region around the construction machine so that a region indicating a component of the construction machine is excluded according to the detected slewing angle, and determining the object as an obstacle when the object detected by the object detection unit is located in the set monitoring region.
