Description

A kind of anchoring drilling machine of base plate with baffler
Technical field
The present invention relates to a kind of anchoring drilling machine, especially a kind of anchoring drilling machine of the base plate with baffler that is applicable to down-hole wet method borehole anchorage.
Technical background
Along with the fast development of China's economic construction, energy demand is very big, and coal resources are difficult to change as the main source of China's energy supply in the future for a long period of time, causes coal industry constantly towards mechanization, automation direction development.The most collieries of China are due to reasons such as coal petrography character, buried depth, crustal stress, and Floor Heave in Roadway destroys serious, affected tunnel and used safety, restricted the safety in production of mine, so jacking of floor management task arduousness.Present stage, China is suspension roof support for the main means of mine floor Reinforcement.At present, the domestic special development of anchoring device for baseboard of coal mine roadway seldom.And the wet method bore mode that now typical anchoring device is used is that the high pressure water that will have fixing water source to provide directly injects the hollow drill pipe of rotation, the gap of the mud mixture of formation by drilling rod and coal (rock) layer squeezed out.For the discharge in safety, rapid cleaning construction, the scientific research personnel has developed the base plate anchoring drilling machine that power is provided by pneumatic motor, has obtained effect very, but because pneumatic motor produces larger noise in the course of the work, add that the space, down-hole is little, environment is severe, and noise is easily struck a chord.Personnel's harm to the operation place is very large, and long-term work, can cause tinnitus, dizziness, weakness of limbs, absent minded, the symptoms such as mood irritability.Therefore, for down-hole provides a kind of base plate anchoring drilling machine that reduces noise, be the on-the-spot large problem solved of being badly in need of.
Summary of the invention
Technical problem: the objective of the invention is to realize the sound-deadening and noise-reducing of base plate anchoring drilling machine, a kind of mining industry baffler of simple in structure, safe and reliable, the working environment that improves down-hole for the staff is provided.
Technological scheme: the anchoring drilling machine of the base plate with baffler of the present invention, comprise the pneumatic motor that is fixed on connecting base one side, the base plate anchoring drilling machine head be connected with pneumatic motor, base plate anchoring drilling machine head is provided with takes out press pump, on connecting base, be connected with the pneumatic motor handrail through gas formula baffler connecting rod, the opposite side of connecting base is provided with air leg, the bottom of connecting base is provided with the operation arm, on described pneumatic motor, be set with pneumatic motor cartridge type baffler, described pneumatic motor handrail is provided with the aerodynamic noise baffler, described aerodynamic noise baffler comprises inside and outside double-layer barrel, be located at the mining silencing cotton in inside and outside double-layer barrel, in inside and outside double-layer barrel, be provided with many row's perforated plates, inside and outside double-layer barrel one end is provided with suction tude, the other end is provided with the diplopore outlet pipe, the motor air outlet of pneumatic motor is connected with the suction tude of aerodynamic noise baffler by the road with the press pump air outlet of taking out of taking out press pump, and above-mentioned two kinds of bafflers include the mining silencing cotton be located between inner/outer tube.
Described many row's perforated plates are 2-4 row; The aperture difference of described many row's perforated plates, front-seat aperture is less than rear round footpath; Described motor air outlet, take out the press pump air outlet and be provided with threeway with the pipeline that the aerodynamic noise baffler is connected.
Beneficial effect: for realizing the noise reduction of base plate anchoring drilling machine noise, the present invention divides two-part to the noise source noise reduction, to by motor gear mechanism engagement and pressurized air the time from the motor relief opening with take out when the press pump relief opening is discharged and produce the noise noise reduction.The noise produced when the motor relief opening with when taking out the press pump relief opening and discharging imports pneumatic motor noise damper inner chamber into by threeway respectively, and arrange perforated plate and the noise reduction of mining silencing cotton impedance complex formula by the gas inner chamber more, final motor and take out press pump gas and discharge by the diplopore exhaust pipe, guarantee the pneumatic working efficiency of base plate anchoring drilling machine; The source swirl gear gear engagement of another noise produces noise, by mining silencing cotton and the anti-combined type noise reduction of single row of perforations plate resistance, it is to take motor as the outside diffusion mode propagation of source point that the engagement of motor gear mechanism produces noise, in the motor outer ring, adds motor cartridge type baffler outwards to propagate by control noise.Many row's perforated plates of the present invention can make the aerodynamic noise baffler have good ventilatory effect, and the diplopore exhaust pipe can make pneumatic drilling machine better ventilate, and avoids the impact on base plate anchoring drilling machine working efficiency.Baffler is around being fixed on the motor periphery, and noise is directly eliminated out the time from the motor internal delivery, reaches better erasure effect.It is simple in structure, reliable operation, effect excellence, has improved underground work personnel's working environment, and major advantage has:
1. from rig exhaust sound and mechanical noise, start with, the noise source main to the base plate anchoring drilling machine carries out sound-deadening and noise-reducing, and structure is also comparatively convenient, and convenient the use, can also reach good sound-deadening and noise-reducing effect simultaneously;
2. adopt the downhole anti-explosion flame resistant material, in use can not produce danger;
3. adopt good ventilation device design, on the not impact of working efficiency of base plate anchoring drilling machine.
