Description
Technical field
The utility model relates to a kind of device that is used for reducing noise, specifically a kind of hammer drill noise reduction damping device.
Background technology
Hammer drill is mainly used in the cutter lane operation in mining and the tunnelling, also is the important tool in railway, water conservancy construction and the national defence stonework.Hammer drill carries out work by the impact grinding principle, and piston is done the high frequency reciprocating motion during work, constantly clashes into bit shank, form strong impact noise and vibrations, under the effect of impact force, drill bit crashes rock, causes secondary pulse noise and vibrations when digging into again.Is example with hammer drill when the excavation operation of down-hole, and recording its sound power level is 124dB (A), and vibration level is also very high.Strong noise vibroseis can cause operating personnel's noise deafness, can cause psychology and physiological multiple disease, reduces efficiency, harm such as overslaugh safety in production.
The utility model content
In order to solve hammer drill noise and shake big problem in use, the utility model proposes a kind of hammer drill noise reduction damping device, this device noise reduction height, resistance coefficient is little, and is in light weight, and volume is little, and is durable, and grease-proof and waterproof carries and easy to maintenance.
The technical scheme that its technical problem that solves the utility model adopts is: this hammer drill noise reduction damping device mainly comprises vibration absorbing handle, the soft sound insulation enclosure of body, air outlet sound absorber, septum pellucidum audio disc and air outlet tube terminal sound absorber; This hammer drill has a body that can produce operation power, and the top of body is provided with air outlet, is connected with the air outlet pipe on this air outlet, to make things convenient for the heat radiation of body; This body one end is connected with the handle that makes things convenient for holding operation, and the other end is connected with shaft-like rotary drill steel and drill bit, makes this machine can break the work of celt rock; The bottom of body is connected with the air leg that is used for supporting body; The outer cover of body is equipped with the soft sound insulation enclosure of body, the air outlet top is provided with the air outlet sound absorber, air outlet extends tuyere tube outside body, the terminal of air outlet pipe is equipped with the convenient air outlet tube terminal sound absorber of installing in addition, air outlet sound absorber and the acting in conjunction of air outlet tube terminal sound absorber, piston is made high frequency and is moved back and forth when reducing work, constantly clashes into the formed intense impact noise of bit shank; Handle is provided with damping spring, forms vibration absorbing handle, and the vibrations when effectively having cushioned body work are to the impact of human body, and the handled easily person grips and operates; The terminal of drill steel and drill bit joint are provided with the septum pellucidum audio disc, and this has not only effectively subdued drill bit rock is crashed the noise that is produced when digging into, and can see through the duty that the septum pellucidum audio disc is observed drill bit easily simultaneously.
The beneficial effects of the utility model are: this hammer drill noise reduction damping device noise reduction height, and resistance coefficient is little, and is in light weight, and volume is little, and is durable, and grease-proof and waterproof carries and easy to maintenance.
