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 of the drum rotation speed of conversion apace.
Background technology
At present in order to adapt to the different condition in coal seam, need be in the coal mining process diameter of cylinder of conversion coal-winning machine, correspondingly, reach best stressed and result of use in order to make the cylinder behind the conversion diameter, the rotating speed of this cylinder also needs conversion.Rocker arm of coal mining machine commonly used in the prior art has only a kind of drum rotation speed usually, in order to reach the purpose of conversion drum rotation speed, need disassemble the running part of rocking arm and change travelling gear, the aforesaid operations process is complicated, cannot say for sure to demonstrate,prove installation accuracy, and easily pollute the lubricated part of rocking arm.
Summary of the invention
Technical problem to be solved by this invention is, a kind of rocker arm of coal mining machine is provided, and it can realize the conversion of drum rotation speed easily.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: rocker arm of coal mining machine comprises that is at least cut two groups, one is cut three 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 groups, second group of duplicate gear is connected with section three groups, and comprise a speed adjusting gear, this speed adjusting gear can comprise a shifting slide gear at least, a pull bar, a handle and a stopping means, shifting slide gear is connected with pull bar, can on section two groups, slide, pull bar is connected with handle, and handle is fixed on the diverse location of stopping means by stretching.Above-mentioned stopping means can be the spacing draw-in groove that comprises 3 stopper slots.
Handle can be fixed in the diverse location of stopping means by stretching, stretching by the speed adjusting gear handle, drive the stretching of pull bar, thereby realize the shifting slide gear position conversion, when shifting slide gear meshes with first group of duplicate gear and second group of duplicate gear respectively, can produce different drum rotation speeds, when shifting slide gear and two groups of duplicate gears did not mesh, drum rotation speed was zero.The user can control to adjust rocking arm according to the difference or the coal seam conditions of diameter of cylinder by the handle of speed adjusting gear drum rotation speed.
Use rocker arm of coal mining machine of the present invention, can realize the conversion of rocking arm drum rotation speed by the operation of speed adjusting gear, convenient to operation, practical.

The specific embodiment
Below, realize the embodiment of double speed rocker arm of coal mining machine of the present invention based on description of drawings.
See also Fig. 1-Fig. 3, at least comprise in the rocker arm of coal mining machine transmission system that is cut two groups 1, one is cut three 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 groups 1, second group of duplicate gear 4 is connected with section three groups 2, first group of duplicate gear 3 is made up of first pinion 5 and first gear 6, second group of duplicate gear 4 is made up of second pinion 7 and second largest gear 8, this transmission system also comprises a speed adjusting gear 9, this speed adjusting gear comprises a shifting slide gear 10 at least, a pull bar 11, a handle 12 and a spacing draw-in groove 13, shifting slide gear 10 is connected with section two groups 1, above-mentioned spacing draw-in groove 13 comprises 3 stopper slots 14,15 and 16, and above-mentioned shifting slide gear 10 and pull bar 11 link to each other by bearing pin, pull bar 11 links to each other with handle 12 by pin, handle 12 can be fixed in the different stopper slots of spacing draw-in groove by stretching, and gear wheel 17 is installed and cut on three groups 2.
In speed governing shown in Figure 2 position, handle 12 is stuck in stopper slot 2 15 positions, shifting slide gear 10 and first group of duplicate gear 3 and second group of all not engagement of duplicate gear 4, rotating speed is an isolation, rotating speed of motor can not reach cylinder, and when shutting down and keep in repair, handle 12 is pulled to this state usually; When handle 12 is pulled to stopper slot 3 16 positions, second largest gear 8 engagements in shifting slide gear 10 and the second group of duplicate gear 4, motor speed can effectively reach cylinder, cuts three groups 2 and cuts that gearratio is the gear ratio of gear wheel 17 and shifting slide gear 10 between two groups 1; When handle 12 is pulled to stopper slot one 14 positions, first gear 6 engagements in shifting slide gear 10 and the first group of duplicate gear 3, motor speed can effectively reach cylinder, cuts three groups 2 and cuts two and organize the gear ratio that gearratio between 1 is first pinion 5 in gear wheel 17 and the first group of duplicate gear 3.
With reference to specific embodiment, although the present invention is illustrated in manual and accompanying drawing, but should be appreciated that affiliated technical field personnel can make multiple change and the alternative wherein multiple parts of multiple equivalent under the situation that does not break away from the scope of the invention defined in the claim.The present invention is not limited to graphic other specific embodiment of accompanying drawing institute, and the conduct described in the manual is at present for implementing the specific embodiment of the contemplated preferred forms of the present invention, and intention of the present invention comprises all embodiments that fall in above-mentioned manual and the appended claim scope.
