Device for controlling blade position of vehicle with caterpillar track
专利汇可以提供Device for controlling blade position of vehicle with caterpillar track专利检索，专利查询，专利分析的服务。并且PURPOSE: To make it possible to control positions of a blade with a high degree of reliability by providing a light receiving device for receiving reference laser beams on the main body of a vehicle with caterpillar track.
CONSTITUTION: Reference laser beams 10 are emitted at a certain height, while a projecting unit of a floodlight projector 1 is being rotated. Upon receipt of the laser beams 10, a receiving device 2, provided on the body of a bulldozer Bu, outputs signals corresponding to a distance ▵h between the position at which the beams were received and the mounting position of the device 2 to controller, while detection signals θ, ϕ and set values are outputted to the controller from an inclination sensor of the body, an angle sensor 4 for sensing rotation angle of a frame 9 and a target height setting device respectively. The controller in turn determines a value L at each operation time to actuate and control a blade lifting mechanism based on the deviation between the measured value L and set value.
