Abstract
The invention relates to a hauling device for a thin seam shearer, in particular to a hauling part for a chain hauled shearer. The hauling part includes a head hauling part and a tail hauling part that are respectively mounted on a head rack and a tail rack of a scraper conveyer. The head hauling part and the tail hauling part both include a hauling motor, the hauling motor is connected to a decelerator fixed in a shroud through a shaft coupling, the decelerator is in connection with a chain wheel through a pin coupling, and a hauling chain positioned in a scraper conveyer chain channel is twined on the chain wheel. The hauling part provided by the invention is installed on the head rack and the tail rack of the scraper conveyer, and the part riding right over the scraper conveyer is only a hauling part omitted shear frame, thus reducing the thickness of the shearer on the scraper conveyer, and ensuring the coal space of the shearer. The hauling part for the chain hauled shearer provided by the invention solves the defects of high machine surface height, narrow and small coal space, complex structure and poor adaptability of existing thin seam electrically hauled shearers.
Description
Technical field
The present invention relates to the draw-gear of low seam mining machinery, be specially a kind of chain hauled shearer tractive unit.
Background technology
Along with the minimizing gradually of coal resources, the girdle coal resources that past difficulty is adopted and do not adopted, also more and more by the attention of people, want this type of resource of high efficiency exploitation, also more and more higher to the requirement of low seam mining machinery.First, low seam mining machinery machine height requires very low by the impact of coal seam thickness, and General Requirements is lower than 1 meter, secondly, coal space crossed by coal-winning machine can not be too narrow and small, cross that coal clear height is minimum is not less than 0.3 meter, otherwise, coal under adopting is difficult to transport away smoothly from work plane, scratch board conveyor its thickness 0.3 meter, so just require in the altitude range of 0.4 meter, design coal-winning machine frame, and traditional double drum electric haulage shearer internal construction is complicated, as shown in Figure 1, the fuselage of electrical haulage shearer comprises frame 3, frame 3 front end is provided with cylinder 1 and rocking arm 2, frame 3 is also provided with guiding tractive unit 4, electric control part and pumping plant etc., each piece volumes is all larger, time all in design and installation to low seam mining machinery, made coal space very narrow and small, by traditional mentality of designing, under ensureing the cutting capacity of coal-winning machine and driving power condition, be difficult in so little space (height of 0.4 meter) and design twin-roll electrical haulage shearer.Therefore the coal-winning machine design concept how broken traditions, in so little space, design the more advanced low seam mining machinery of performance, solution traditional double cylinder low seam mining machinery machine height is high, coal narrow space, baroque problem seem particularly urgent excessively.
Summary of the invention
There is to solve existing low seam electric traction coal mining machine the problem that machine height is high, cross coal narrow space, complex structure and adaptation difference in the present invention, provides a kind of chain hauled shearer tractive unit.
The present invention adopts following technical scheme to realize: a kind of chain hauled shearer tractive unit, comprise nose towing portion and tail tractive unit, on the headstock that nose towing portion and tail tractive unit are installed on scratch board conveyor respectively and aircraft tail shelf, nose towing portion and tail tractive unit all comprise traction electric machine, traction electric machine is connected with the reducer be fixed in cover cylinder by shaft coupling, reducer is connected with sprocket wheel by pin coupler, sprocket wheel is wound with the haulage chain being positioned at scratch board conveyor chain road.
Haulage chain is connected with drag hook with the cutting units of the coal-winning machine be located on scratch board conveyor, traction electric machine is connected with the high speed shaft of reducer by shaft coupling, by the reduction of speed of reducer, increase to turn round and to be connected with sprocket wheel with pin coupler afterwards, band movable sprocket rotates, sprocket wheel drives haulage chain movable in the chain road of scratch board conveyor, haulage chain is connected with winning machine cutting part drag hook, winning machine cutting part is just along with haulage chain is together in slippage on scratch board conveyor, realize the walking function of coal-winning machine like this, on the headstock that tractive unit provided by the invention is installed on scratch board conveyor and aircraft tail shelf, the part ridden over directly over scratch board conveyor is only that a coal-winning machine frame saving tractive unit is (as less in this frame thickness of Fig. 2, crossing coal clear height is 0.4 meter), which reduce the thickness of coal-winning machine on scratch board conveyor, what ensure that coal-winning machine crosses coal space.
The present invention is directed to the defect that existing low seam electric traction coal mining machine machine height is high, cross coal narrow space, complex structure, bad adaptability, after said structure design, this coal-winning machine is had, and volume is little, structure is simple, strong adaptability, the feature such as advanced in performance.
