[CN202111057131.X] Self-generating wind pressure electromagnetic combined impact self-rotating air hammer and use method thereof
[CN202111057131.X] A self-generating wind pressure electromagnetic combined impact self-rotating air hammer and its use method Title: A self-generating wind pressure electromagnetic combined impact self-rotating air hammer and its use method Application number: CN202111057131.X Applicant: Southwest Petroleum University Application Date: 2021-9-9 Patent Type: Invention Application The present invention provides a self-generating wind pressure electromagnetic combined impact self-rotating air hammer and its use method. It includes a power component, a component, a piston, a power component, a bit, the power generation assembly includes an upper joint, an intermediate joint, a turbine, a turbine shaft, an insulating square box, a generator, an elastic pad, and a positioning block. The upper joint and the intermediate joint are connected by threads, and the two positioning blocks are installed inside the intermediate joint. The insulating square box is located in the square cavity formed by the two positioning blocks. The bottom of the insulating square box is an elastic pad, and the upper part of the elastic pad is an installed generator, the turbine and the generator are connected by a turbine shaft. The invention makes the drill bit receive greater impact force to assist rock breaking, and the hybrid stepping motor type rotating assembly provides greater torque to rotate the drill bit, reduces the energy loss when high-pressure gas is used as rotating power, and accurately controls the angle of rotation of the drill bit.
