Abstract
The invention discloses a middle trough with pin rails on two sides. The middle trough comprises an insertion board ledge, a middle plate, a bottom plate and a baffle ledge, which are connected into a whole. A rail support is arranged outside the baffle ledge, and a pin rail is connected to the rail support. An insertion board is arranged on the insertion board ledge. Offset pin rails are arranged outside the insertion board ledge, and form a coal mining machine driving traveling supporting rail. Each offset pin rail comprises a connecting seat and rail teeth, which are integrated. The connecting seats are connected with a trough body. A plurality of linearly arranged rail teeth are uniformly arranged along the length direction of each connecting seat on the connecting seat. The pin rails are arranged on the two sides of the trough body, the offset pin rails outside the insertion board ledge form the coal mining machine driving traveling supporting rail, and the pin rail outside the baffle ledge guides the traveling of a coal mining machine. The machine surface of the coal mining machine is low, and has a large coal delivery space, so that the problem of clamping between a driving wheel and the pin rail during the work of the coal mining machine can be effectively solved, the coal mining machine stably and reliably runs, and is low in failure rate, and improvement in the coal mining efficiency of fully-mechanized excavation of an extremely thin coal seam is facilitated.
Description
Technical field
The invention belongs to the The middle pan of scraper conveyor technical field, specifically relate to a kind of ultra-thin coal seam and combine the intermediate channel that adopts drag conveyor.
Background technology
Divide according to the China's coal-mine coal seam thickness, be in the girdle that is of 0.8m-1.3m thickness, be in the ultra-thin coal seam that is of the following thickness of 0.8m.Thin and ultra-thin coal seam belongs to difficult mining coal seam, and about 6,000,000,000 tons of the explored recoverable reserves in this part coal seam accounts for about 20% of national coal storage total amount, and ultra-thin coal seam reserves wherein account for 14% of difficult mining coal seam.Difficult mining coal seam is high to the machine height requirement of fully-mechanized mining equipment, and the exploitation difficulty is big, exploits output at present and is merely 10% of total output.In order to improve energy recovery ratio and production efficiency, design and produce the key that machine height is low, the big fully-mechanized mining equipment of mistake coal amount has become solution ultra-thin coal seam mining problem.The existing drag conveyor that uses, center groove all are provided with the pin rail in the baffle plate outside, and the pin rail is between cell body and support push unit, for the walking of coal-winning machine driving wheel provides support.And, all take biasing setting with the supporting coal-winning machine of conveyer in order to adapt to the exploitation of ultra-thin coal seam, just cut drive unit and the travel driving unit with conveyer is installed in the side near the shovel plate, so that reduce coal-winning machine fuselage height; Because coal mining machine roller was located in the body far-end originally, the problem of thereupon bringing is that skew has taken place for coal-winning machine center of gravity and drag conveyor center of gravity, and further from the coal-winning machine driving wheel of advancing, the coal-winning machine center of gravity drives support and lays respectively at the coal-winning machine both sides with advancing.When the coal-winning machine running part when haulage shearer moves ahead owing to receive the influence of centre-of gravity shift, driving wheel and scraper plate machine pin rail usually take place not block; Walking resistance is big, and operation is unstable, and long-play causes device damage easily; Initiating failure, not only cost of production is high, and inefficiency.
Summary of the invention
The technical problem that the present invention will solve provides a kind of adaptation ultra-thin coal seam and combines and to adopt, and coal-winning machine operates steadily, not fragile, bilateral pin rail intermediate channel that fault rate is low.
For solving the problems of the technologies described above; The present invention includes the shovel board slot group that fuses, middle plate, base plate and baffle plate ledge, the said baffle plate ledge outside is provided with rail chair, is connected with the pin rail on the rail chair; The shovel board slot is helped and is provided with the shovel plate; Its design feature is that the shovel board slot group outside is provided with the offset pins rail, and said offset pins rail drives the walking supporting track as coal-winning machine, and it comprises the Connection Block and the rail tooth of integral type; Connection Block is connected with cell body, and its length direction of Connection Block upper edge evenly is provided with a plurality of linearly aligned rail teeth that are.
Preferably said offset pins rail is monolateral supporting pin rail, and the rail tooth is located at the Connection Block outside, and its inner is connected with Connection Block.
The external side of more preferably said shovel board slot group of group is provided with hangers, is provided with bracket and holder above the shovel plate, and the Connection Block inboard is provided with corresponding with hangers and bracket respectively plug-in type dop, is equipped with pin-and-hole on holder and the Connection Block; The offset pins rail is articulated in the external side of shovel board slot group of group through the inboard dop of Connection Block, and Connection Block two ends and holder join, and connect through connecting pin.
Said holder is provided with 2 pin-and-holes, and one of them is the prolate shape positioning hole.
After adopting said structure, owing to be provided with the pin rail in the cell body both sides, the offset pins rail in the shovel board slot group outside is positioned at coal-winning machine center of gravity bottom, is that coal-winning machine drives the walking supporting track, and the pin rail of baffle plate ledge side is for the coal-winning machine walking provides guiding.The track of coal-winning machine both sides and intermediate channel both sides joins, and not only can reduce its machine height greatly, for coal-winning machine gap bridge section provided the coal space; And the coal-winning machine center of gravity is with to drive supporting point position more approaching, during work, can effectively solve the coal-winning machine driving wheel and the pin rail does not block problem; Coal-winning machine operates steadily on the scraper plate machine reliably, and fault rate is low, is difficult for causing device damage and initiating failure; Cost of production is low, also helps improving ultra-thin coal seam and combines the coal mining efficient of adopting.
