Problems solved by technology

In addition, the detection values ​​of these sensors will contain noise caused by the operation of the attachment and the rotation operation.
Therefore, when judging whether the excavator exists on a flat terrain or an unstable terrain such as a slope, it is possible to make a wrong judgment.

Embodiment Construction

[0034] First, refer to figure 1 An excavator as a construction machine according to an embodiment of the present invention will be described. in addition, figure 1 It is a side view of the excavator of the embodiment of the present invention. exist figure 1 In the illustrated excavator, an upper revolving body 3 is mounted on an undercarriage 1 via a revolving mechanism 2 . A boom 4 is attached to the upper revolving body 3 . An arm 5 is attached to the tip of the boom 4 , and a bucket 6 is attached to the tip of the arm 5 . The boom 4 , the arm 5 , and the bucket 6 as working elements constitute an excavation attachment as an example of attachments. In addition, the attachments may be other attachments such as bottom excavation attachments, leveling attachments, and dredging attachments. In addition, boom 4 , arm 5 , and bucket 6 are hydraulically driven by boom cylinder 7 , arm cylinder 8 , and bucket cylinder 9 , respectively. In addition, a cab 10 is provided on the...

Abstract

The invention relates to an excavator capable of improving determination precision, thus preventing unstable state of the machine; the excavator comprises the following structures: a lower driving body (1); an upper rotary body (3) mounted on the lower driving body (1); an excavation attaching device arranged on the upper rotary body (3); an operation content detector (29) detecting operation content; a position finding device (M2) measuring position and direction of the machine; a posture detector (M3) used for detecting the posture of the excavation attaching device; an external operating device (30E) having a landscape gaining portion (33). According to the posture propelling of the excavation attaching device, the information obtained by the landscape information gaining portion (33) and related to the present shape of the ground of a working object, and the location of the excavator, the stable/unstable states of the excavator can be determined, thus providing basis for limiting excavator motions when the machine is unstable.

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2015-051370 filed on March 13, 2015 and Japanese Patent Application No. 2015-052619 filed on March 16, 2015. The entire contents of these Japanese applications are incorporated herein by reference. [0002] The present invention relates to an excavator provided with an attachment. Background technique [0003] Known excavators are known to determine whether they are in an uphill state or a downhill state based on the state from a hydraulic pump to a traveling device, the inclination angle of a vehicle, or the rotational speed of an engine driving a hydraulic pump during travel (refer to Patent Literature 1). [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 2-212674 [0005] However, the excavator described above uses an inclination sensor or the like in order to detect the state of the vehicle. In addition, the detection values ​​of these sensors contain ...
