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

Bilateral pin rail intermediate channel
Technical field
The invention belongs to 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
According to China's coal-mine coal seam thickness divide, in 0.8m-1.3m thickness be girdle, in the following thickness of 0.8m is ultra-thin coal seam.Thin and ultra-thin coal seam belongs to difficult mining coal seam, and approximately 6,000,000,000 tons of the explored recoverable reserves in this part coal seam account for 20% left and right 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 requires high to the machine height of fully-mechanized mining equipment, exploitation difficulty is large, and exploiting at present output is only 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 large fully-mechanized mining equipment of mistake coal amount has become solution ultra-thin coal seam mining problem.The drag conveyor of existing use, its intermediate channel is all provided with pin rail in baffle plate outside, and pin rail is between cell body and support push unit, for the walking of coal-winning machine driving wheel provides support.And in order to adapt to the exploitation of ultra-thin coal seam, all take biasing setting with the coal-winning machine that conveyer is supporting, namely the cut drive unit of conveyer and travel driving unit are arranged on to the side near shovel board, to reduce coal-winning machine fuselage height; Because coal mining machine roller was located in body far-end originally, the problem of thereupon bringing is that skew has occurred for coal-winning machine center of gravity and drag conveyor center of gravity, and further from the coal-winning machine driving wheel of advancing, coal-winning machine center of gravity lays respectively at coal-winning machine both sides with advancing to drive to support.When Walk Part of Shearer is when haulage shearer moves ahead, owing to being subject to the impact of centre-of gravity shift, driving wheel and scrapper conveyor pin rail usually occur not block, walking resistance is large, and operation is unstable, and long-play easily causes device damage, initiating failure, not only cost of production is high, and inefficiency.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of ultra-thin coal seam that adapts to and combines and adopt, and coal-winning machine operates steadily, the bilateral pin rail intermediate channel of not fragile, failure rate is low.
For solving the problems of the technologies described above, the present invention includes the shovel board ledge being connected, middle plate, base plate and baffle, described baffle outside is provided with rail chair, on rail chair, be connected with pin rail, shovel board ledge is provided with shovel board, its design feature is that shovel board ledge outside is provided with offset pins rail, described offset pins rail drives walking supporting track as coal-winning machine, it comprises Connection Block and the rail tooth of integral type, Connection Block is connected with cell body, is evenly provided with along its length multiple linearly aligned rail teeth that are on Connection Block.
Preferably described offset pins rail is monolateral supporting pin rail, and rail tooth is located at Connection Block outside, and its inner is connected with Connection Block.
More preferably described shovel board ledge helps external side to be provided with hangers, is provided with bracket and holder above shovel board, and Connection Block inner side is provided with respectively the plug-in type dop corresponding with hangers and bracket, on holder and Connection Block, is equipped with pin-and-hole; Offset pins rail is articulated in shovel board ledge by the dop of Connection Block inner side and helps external side, and Connection Block two ends and holder join, and connect by connecting pin.
Described holder is provided with 2 pin-and-holes, and one of them is prolate shape positioning hole.
Adopt after said structure, owing to being provided with pin rail in cell body both sides, the offset pins rail in shovel board ledge outside is positioned at coal-winning machine center of gravity bottom, is that coal-winning machine drives walking supporting track, and the pin rail of baffle side, for coal-winning machine walking provides guiding.The track of coal-winning machine both sides and intermediate channel both sides joins, not only can greatly reduce its machine height, for coal-winning machine gap bridge section provided coal space, and coal-winning machine center of gravity is more approaching with driving supporting point position, during work, coal-winning machine driving wheel can effectively be solved and pin rail does not block problem, coal-winning machine operates steadily reliably on scrapper conveyor, and failure rate is low, is difficult for causing device damage and initiating failure, cost of production is low, is also conducive to improve ultra-thin coal seam and combines the coal mining efficiency of adopting.
