Low-noise environment-friendly hydraulic power driven mechanical drilling equipment

Abstract

The invention relates to the technical field of mechanical drilling, and discloses low-noise environment-friendly hydraulic power driven mechanical drilling equipment which comprises a fixed cylinder, wherein a limiting noise reduction mechanism and an active noise reduction mechanism are arranged in the fixed cylinder; the limiting noise reduction mechanism comprises a hydraulic telescopic cylinder, a motor, a motor shaft, a drill bit, a first annular shell, a second annular shell, a third annular shell, a first fixing plate, a first fixing rod, a second fixing plate and a second fixing rod; the hydraulic telescopic cylinder is connected to the top end in the fixed cylinder through bolts, the motor is fixedly connected to the bottom of the hydraulic telescopic cylinder, and a motor shaft is rotationally connected to the bottom of the motor. The annular shells are arranged on the motor, the motor shaft and the drill bit, noise can be absorbed by round holes in the three annular shells, an annular plate and a curved elastic piece respectively, the noise can be reduced, meanwhile, the annular shells can limit the motor shaft and the drill bit, the situation that the motor shaft and the drill bit shake too much is avoided, and the overall vibration is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical drilling, in particular to low-noise and environment-friendly hydraulic power driven mechanical drilling equipment. Background technique [0002] With the advancement of science and technology, the productivity has also improved rapidly, and the advent of the information age has had a great impact on mechanized equipment, leading and changing the development direction of mechanical equipment.

AI Technical Summary

Problems solved by technology

[0004] However, in the existing hydraulic power-driven mechanical drilling equipment, the noise reduction and shock absorption methods are relatively simple during the drilling process, and the effects of noise reduction and shock absorption cannot be greatly improved. At the same time, during drilling, due to The connection between the vibration fixing bolt and the ground is easy to loosen, which will lead to safety accidents
