Abstract
The utility model relates to an epicyclic transmission electric coal drill of a water injection type, which changes the past structural form that an output shaft and a driving shaft eccentrically drill holes. An epicyclic retarding mechanism is used for leading a rotor shaft, an epicyclic gear carrier and an output shaft to be on the same axial line, and radial vibration is effectively reduced. A water injection device is also arranged at a front cover, and water can enter a coal rock hole through a drill rod to eliminate dust pollution produced by drilling holes. The utility model not only can effectively relieve the vibration fatigue of workers and improve the quality of drilling holes, but also can overcome the dust pollution of drilling holes and improve working environment.
Description
Technical field
The utility model relates to a kind of electric coal drill, refers to a kind of Gear Planet Transmission water injection type electric coal drill especially.
Background technology
At present, at the employed trestle formula revolution of colliery scope of operation electric coal drill,, hole by output shaft drive drill bushing and drill bit usually by one-level or double reduction gear.Because the axis of output shaft and driving shaft is not in same axial location, eccentric throw is about 40 millimeters, under eccentric state, hole, its vibration causes drilling rod more radially amplitude to occur, make the aperture that is bored the irregular and serious phenomenon that trains off often occur, not only influence drilling quality, make troubles to follow-up work, the operating personnel is that the vibration and the eccentric resistance that overcome drilling rod must be paid big labour intensity.
When carrying out drilling in coal and rock in the down-hole, the gas in the coal petrography can be overflowed the fricative spark of drill bit and coal petrography, the danger of the gas explosion of hiding along boring.Drilling in coal and rock can cause dust pollution in addition, and harmful operating personnel's is healthy
The utility model content
The purpose of this utility model be exactly to provide a kind of can alleviate because of the off-centre of driving shaft and output shaft produce than large amplitude, can overcome the Gear Planet Transmission water injection type electric coal drill of the dust pollution that produces because of dry drilling again.
The utility model comprises casing, armature spindle, output shaft, motor, and its reducer is a planetary wheeling mechanism.Pinion frame and output shaft are one, the sun gear of the end of armature spindle and the engagement of the planetary gear on the pinion frame.Ring gear is fixed on the casing, planetary gear and ring gear engagement.Armature spindle, pinion frame and output shaft are on the same axis.On the protecgulum of casing front end water filling device is housed, the annular water tank in its pipeline and the protecgulum communicates, output shaft axially be processed with water injection hole, output shaft radially be processed with through hole, the two-port of through hole all communicates with annular water tank.Valve is housed on water filling device.
In order to prevent that water filling from entering electric coal drill inside, is equiped with sealed bearing on pinion frame, output shaft and the armature spindle.
Solve the eccentricity issues of electric coal drill driving shaft and output shaft by planetary gear speed reducing mechanism, armature spindle, pinion frame and output shaft are existed together on the axis, effectively reduced radial vibration, obviously alleviated operating personnel's labour intensity, guaranteed the drilling in coal and rock quality; By water filling device, effectively overcome the dust pollution that produces because of boring, further improve operating environment.
Description of drawings
Fig. 1 is the utility model partial structurtes schematic diagrames.
Reference numeral:
1 casing, 2 reducer bonnets, 3 ring gears, 4 annular water tanks, 5 output shafts, 6 water injection holes, 7 valves, 8 water filling devices, 9 through holes, 10 pinion frames, 11 sun gears, 12 sealed bearings, 13 planetary gears, 14 armature spindles, 15 motors, 16,17 sealing rings, 18 sealed bearings, 19 planetary wheeling mechanisms, 20 protecgulums, 21 sealed bearings
The specific embodiment
With reference to Fig. 1.The utility model comprises casing 1, armature spindle 14, motor 15.Its reducer is a planetary wheeling mechanism 19.Pinion frame 10 is an one with output shaft 5, and its two ends cooperate with sealed bearing 12,18 respectively.The front end of armature spindle is a sun gear 11, the planetary gear engagement on it and the pinion frame 10.Three planetary gears are equilateral triangle and are distributed in the sun gear circumference, also can be four planetary gears and are square profile at the sun gear circumference.Ring gear 3 is fixed on the casing.Armature spindle, pinion frame and output shaft go out on same axis.On the protecgulum 20 of casing front end, water filling device 8 is housed, valve 7 is housed on the water filling device.Annular water tank 4 in water filling device and the protecgulum communicates, output shaft axially be processed with water injection hole 6, output shaft radially be processed with through hole 9, the two-port of through hole all communicates with annular water tank.Sealed bearing 21 on the armature spindle, the outer ring of the sealed bearing 18 on the pinion frame cooperate with the reducer bonnet.
