Hybrid power bulldozer and leveling system and leveling method thereof

Abstract

The invention discloses a hybrid power bulldozer and a leveling system and a leveling method thereof. The leveling system of the hybrid power bulldozer comprises a supporting frame, a working face, a laser emitter, a laser receiver and a controller, wherein the working face is arranged on the hybrid power bulldozer; the laser emitter which is provided with a laser head which can rotate and emit laser signals is arranged on the supporting frame; the laser receiver which is fixed relative to a bulldozer body of the hybrid power bulldozer is used for receiving the laser signals emitted from the laser emitter; the laser receiver sends the received laser signals to the controller and the controller outputs corresponding controlling signals to a lift controlling device of a perching knife of the hybrid power bulldozer according to the received laser signals. With a light plane formed by laser as a benchmark reference surface, the hybrid power bulldozer and the leveling system and the leveling method of the hybrid power bulldozer have the advantages of being not interfered by the cluster operation and other factors and ensuring the leveling effect consequently due to the fact that the benchmark reference surface is a stable plane which is located at a certain spatial height.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a hybrid bulldozer, a leveling system and a leveling method thereof. Background technique [0002] The power of the hybrid bulldozer comes from the motor instead of the engine directly. This design makes the hybrid bulldozer have the advantages of energy saving and environmental protection. It is widely used in the field of construction machinery, such as farmland basic construction, water conservancy and hydropower projects, road and railway construction , airport construction and municipal engineering technical fields. [0003] The leveling of the road surface after construction is an important indicator of the operating performance of the hybrid bulldozer. Therefore, the hybrid bulldozer needs to be leveled during operation, that is, the road surface after the blade operation is kept on the same plane. At present, the leveling of hybrid bulldozers is mainly real...

Problems solved by technology

[0006] First, since the GPS measurement is to receive the signal transmitted by the satellite, and then process the signal to obtain the point coordinates, when any factors that may affect the signal reception interfere, the measured point coordinates may produce errors

For the above reasons, this leveling method is not suitable for environments with narrow field of view and obstacles within the viewing angle, especially not suitable for working in old urban areas; it is also susceptible to interference from high-power radio transmission sources and high-voltage transmission lines, and is not suitable for large areas. Water areas, affecting the operation of hybrid tractors in such environments

[0007] First, with the digitization of the earth, the structure of the GPS three-dimensional control system is complex and the cost is high
