Abstract

The invention discloses a rotary drilling rig energy saving method and system and a rotary drilling rig. The method includes the steps that energy saving working modes input by a user are received; an engine control instruction, a hydraulic pump control instruction and a power head motor control instruction corresponding to the energy saving working modes are determined according to the energy saving working modes; the engine control instruction, the hydraulic pump control instruction and the power head motor control instruction are sent to an engine, a hydraulic pump and a power head motor respectively to control the engine, the hydraulic pump and the power head motor to work under working parameters corresponding to the energy saving working modes respectively. The energy saving working modes are set, each mode is considered from the engine-hydraulic pump-power head motor global view, the engine rotating speed, the pump displacement and the motor displacement are optimally set, and therefore optimization of power output of a power head and fuel consumption of the engine can be achieved.

Description

technical field [0001] The invention relates to the field of construction machinery energy saving, in particular to an energy saving method and system for a rotary drilling rig and the rotary drilling rig. Background technique [0002] In foundation engineering construction, rotary drilling rig is a large-scale foundation construction machinery equipment suitable for hole-forming operations in building foundation engineering, and is widely used in foundation construction projects such as municipal construction, highway bridges, and high-rise buildings. As the country and society continue to advocate the promotion of energy-saving and environmental protection technologies, rotary drilling rig users are also more and more concerned about the fuel consumption and fuel cost of the whole machine. [0003] At present, rotary drilling rigs generally adopt the power transmission form of "engine-hydraulic pump-multi-way valve-power head motor". The controlled constant power variable...
