Description
Technical field
The present invention relates to a kind of rocker arm of coal mining machine, especially relate to a kind of rocker arm of coal mining machine that can convert drum rotation speed rapidly.
Background technology
At present in order to adapt to the different condition in coal seam, need the diameter of cylinder converting coal-winning machine in coal mining process, correspondingly, in order to the cylinder after making conversion diameter reaches best stressed and result of use, the rotating speed of this cylinder also needs conversion.Rocker arm of coal mining machine conventional in prior art only has a kind of drum rotation speed usually, in order to reach the object of conversion drum rotation speed, need disassemble the running part of rocking arm and change travelling gear, aforesaid operations process is more complicated, comparatively be difficult to ensure card installation accuracy, and easily pollute the lubrication portion of rocking arm.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of rocker arm of coal mining machine, and it can realize the conversion of drum rotation speed easily.
The present invention solves the problems of the technologies described above adopted technical scheme: rocker arm of coal mining machine at least comprises one and cuts two axle groups, one is cut three axle groups, first group of duplicate gear and second group of duplicate gear, above-mentioned duplicate gear is respectively the conjuncted of two kinds of different number of teeth gears, wherein first group of duplicate gear is connected with section two axle groups, second group of duplicate gear is connected with section three axle groups, and comprise a speed adjusting gear, this speed adjusting gear at least can comprise a shifting slide gear, a pull bar, one handles and a stopping means, shifting slide gear is connected with pull bar, can slide in section two axle groups, pull bar is connected with handle, handle is fixed on the diverse location of stopping means by stretching.Above-mentioned stopping means can be the spacing draw-in groove comprising 3 stopper slots.
Handle can be fixed in the diverse location of stopping means by stretching, by the stretching of speed adjusting gear handle, drive the stretching of pull bar, thus realize shifting slide gear position conversion, when shifting slide gear engages with first group of duplicate gear and second group of duplicate gear respectively, can produce different drum rotation speeds, when shifting slide gear does not engage with two groups of duplicate gears, drum rotation speed is zero.User can control to adjust the drum rotation speed of rocking arm according to the difference of diameter of cylinder or coal seam conditions by the handle of speed adjusting gear.
Use rocker arm of coal mining machine of the present invention, the conversion of Rocker drum rotating speed can be realized by the operation of speed adjusting gear, convenient to operation, practical.

Detailed description of the invention
Below, the embodiment realizing double speed rocker arm of coal mining machine of the present invention is described based on accompanying drawing.
Refer to Fig. 1-Fig. 3, at least comprise one in rocker arm of coal mining machine transmission system and cut two axle groups 1, one is cut three axle groups 2, first group of duplicate gear 3 and second group of duplicate gear 4, wherein first group of duplicate gear 3 is connected with section two axle groups 1, second group of duplicate gear 4 is connected with section three axle groups 2, first group of duplicate gear 3 is made up of the first pinion 5 and first gear 6, second group of duplicate gear 4 is made up of the second pinion 7 and second largest gear 8, this transmission system also comprises a speed adjusting gear 9, this speed adjusting gear at least comprises a shifting slide gear 10, a pull bar 11, one handles 12 and a spacing draw-in groove 13, shifting slide gear 10 is connected with section two axle groups 1, above-mentioned spacing draw-in groove 13 comprises 3 stopper slots 14, 15 and 16, and above-mentioned shifting slide gear 10 is connected by bearing pin with pull bar 11, pull bar 11 is connected with handle 12 by pin, handle 12 can be fixed in the different stopper slots of spacing draw-in groove by stretching, gear wheel 17 is installed and is cut in three axle groups 2.
Speed governing position shown in Fig. 2, handle 12 is stuck in stopper slot 2 15 position, and shifting slide gear 10 does not all engage with first group of duplicate gear 3 and second group of duplicate gear 4, rotating speed is isolation, the rotating speed of motor can not reach cylinder, and usually when shutting down and keep in repair, handle 12 is pulled to this state; When handle 12 is pulled to stopper slot 3 16 position, shifting slide gear 10 engages with second largest gear 8 in second group of duplicate gear 4, and motor speed effectively can reach cylinder, and cutting three axle groups 2 and cutting gearratio between two axle groups 1 is the gear ratio of gear wheel 17 and shifting slide gear 10; When handle 12 is pulled to stopper slot one 14 position, shifting slide gear 10 engages with first gear 6 in first group of duplicate gear 3, motor speed effectively can reach cylinder, cuts three axle groups 2 and cuts the gear ratio that gearratio between two axle groups 1 is the first pinion 5 in gear wheel 17 and first group of duplicate gear 3.
With reference to specific embodiment, although the present invention is illustrated in the specification and illustrated in the drawings, but should be appreciated that when not departing from the scope of the invention defined in claim, art personnel can make multiple change and the alternative wherein multiple parts of multiple equivalent.The present invention is not limited to accompanying drawing institute graphic other specific embodiment, and the specific embodiment as the preferred forms at present contemplated by enforcement the present invention described in manual, and intention of the present invention comprises all embodiments fallen in above-mentioned manual and appended right.
