no. 1 Embodiment

[0022] figure 1 It is a diagram showing a laser level detection system including: a rotating laser device 11 installed at a predetermined position on a flat ground via a tripod 10; a level detection device 20 mounted on the arm of a hydraulic excavator (construction vehicle) 12 13 ; and an operating device (remote operating device) 60 disposed in the cab 14 of the hydraulic excavator 12 . A bucket (work implement) 15 is swingably attached to a tip end of an arm 13 of the hydraulic excavator 12 , and the arm 13 is attached to a tip end portion of a boom 16 . Then, by driving the boom hydraulic cylinder 17 and the arm hydraulic cylinder (not shown), the boom 16 and the arm 13 are operated to move the bucket 15 up and down or back and forth, and by driving the bucket hydraulic cylinder (not shown) And make the bucket 15 swing.

[0023] The rotating laser device 11 emits laser light P and rotates the laser light P around a vertical axis J to form a reference plane.

no. 2 Embodiment

[0056] Figure 7 It is a figure which shows 2nd Example. In this second embodiment, a first level detection device 110 is provided on the rod 102 provided on the blade (working device) 101 of the bulldozer (construction vehicle) 100, On the rod 104 on the device) 103, the 2nd level detection device 120 is provided, and the 1st level detection device 110 is made of level detection device 21,31,41 equally with the 1st embodiment, and the 2nd level detection device is made of level The detection device 21', 31', 41' constitutes. The first level detection device and the second level detection device are separated from each other, the level detection devices 21, 31, 41 are spaced apart from each other in the vertical direction, and the level detection devices 21', 31', 41' are also mutually spaced from each other in the vertical direction. configured separately. Next, in the cab 100A of the bulldozer 100, the operating device 160 having the same structure as the operating device...

no. 3 Embodiment

[0061] Figure 8 The structure of the laser level detection system of the third embodiment is shown. In this third embodiment, the same operating device 301 as the operating device 60 of the first embodiment is disposed in the monitoring room 300. figure 1 ) operating device 60, and bulldozer 100 (refer to Figure 7 ) between the operating devices 160 of the operating device 160 to transmit and receive signals wirelessly, so that the light receiving positions of the light receiving parts of the level detecting devices of the level detecting devices 20, 110, 120 are displayed on the display part (not shown) of the operating device 301 , and the difference between the reference position of the light receiving part. In this way, the progress of each job site can be monitored remotely.

[0062] The operation device 301 is a device that is set as the master by a master / slave switch (not shown) and is set to a display mode by a mode switch (not shown) so that the difference is di...

Abstract

The invention provides a laser level detection system which is needless of changing the installing position of the level detection means even in the case where different leveling parts of different heights are leveled respectively. The system comprises: the rotational laser device for making the reference surface for rotating the laser beam around the axis as well as emitting the laser beam; the level detection means for detecting the height of the bucket of the shovel car by receiving the laser beam; and the operation device arranged in the driving room. The level detection means comprises: a plurality of level detection devices arranged in a vertical direction, each level detection device extends in vertical direction and provided with a light receiving part for receiving the laser beam, and outputs the data corresponding to the difference of reference light receiving position of the laser beam, the operation device receives the data and displays the difference by receiving the data.

Description

technical field [0001] The present invention relates to a laser level detection system. For example, a level detection device is installed on the arm of a bucket of a construction vehicle such as an excavator. The level detection device detects a laser as a reference, and the information of the level detection device is displayed on the on the display unit in the cab of the construction vehicle. Background technique [0002] Conventionally, there has been known a laser detection and operating device for construction machinery in which a level sensor (level sensor) is mounted on a rod extending upward from a blade of a bulldozer, and the laser light of a rotating laser device is received by the level sensor, Based on the light-receiving position of the level sensor, the deviation from the optimum height is displayed on a remote display (refer to Patent Document 1). [0003] In this laser detection and operation device for construction machinery, the height from the ground of...
