A multifunctional drilling rig using power frequency power as power

Abstract

The invention discloses a multifunctional drill machine taking a power-frequency power supply as power. The multifunctional drill machine comprises an oil pump drive device connected to the power-frequency power supply and a drill machine hydraulic system. The oil pump drive device comprises a controller, a frequency converter, a variable frequency motor and an oil pump, wherein the controller and the frequency converter are both connected to the power-frequency power supply; and the frequency converter is used for receiving a variable frequency regulation signal sent from the controller and regulating the frequency of a working power supply of the variable frequency motor according to the variable frequency regulation signal so as to further change the rotating speed of the variable frequency motor and further change the output flow of the oil pump connected with the variable frequency motor. The multifunctional drill machine has the advantages of being subjected to soft start and soft stop, free of impact current and subjected to stepless speed regulation by changing the driving way of the oil pump, the working performance of the drill machine is remarkably improved in comparison with that of the prior art, the fault rate of the drill machine is low, and the drill machine is economic in running and low in energy consumption, realizes zero discharge and has the outstanding effects of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a drilling rig which integrates a long auger drilling rig, a rotary drilling rig and a hydraulic vibratory hammer and uses a power frequency power supply as power. Background technique [0002] At present, in the piling machinery industry, long auger drilling rigs, rotary drilling rigs, hydraulic vibratory hammers, etc. are commonly used several types. In the traditional piling machinery industry, diesel engines are mostly used as the power source for driving oil pumps, but Since the diesel engine uses diesel, diesel will produce a lot of exhaust gas when it is burned, and the diesel engine is a high-power system that consumes a lot of energy while generating power. Diesel engines are gradually unable to meet the demand. [0003] To sum up, how to reduce the consumption of energy and the failure rate of the machine, and how to achieve both economical and environmental effect...
