Abstract
The utility model relates to a single-cogged-rack scraper conveyer used for exploiting a thin coal seam. The conveyer is characterized in that a shovel plate mechanism is arranged on one side of a coal face of a middle groove; a cogged rack is arranged on the shovel plate mechanism and comprises cogs and hooks; a coal cutter guide device is arranged on the side of a baffle ledge; the shovel plate mechanism comprises a shovel plate, a shovel plate ledge at the rear end of the shovel plate, suspension loops on the shovel plate ledge and cogged rack fixed bases on the shovel plate; the shovel plate is also provided with fixture blocks which are buckled with the hooks on the cogged rack; locating blocks on the cogged rack are buckled on the suspension loops on the shovel plate ledge. According to the utility model, the positioning mode of the cogged rack on the shovel plate mechanism is simple and effective, and disassembly and maintenance are facilitated. The cogged rack is arranged on the shovel plate close to a coal cutter, and a series of transmitting devices stretching across the upper end of the scraper conveyer are omitted, so that the height of the coal cutter is reduced and the scraper conveyer is suitable for thin coal seam. The coal cutter guiding device is arranged on the side of the baffle ledge, so that the travel guiding of the coal cutter is achieved, and the effect of balancing the coal cutter is realized.
Description
Technical field
The utility model relates to a kind of ultra-thin coal seam mining machines, illustrates further as being used for the single face rack rails drag conveyor of exploitation ultra-thin coal seam.
Background technology
Divide according to the China's coal-mine coal seam thickness, coal seam thickness is girdle below 1.3m, and wherein coal seam thickness is ultra-thin coal seam below 0.8m.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%, about 900,000,000 tons of reserves.The exploitation output of girdle only is 10% of gross reserves, and the yield of ultra-thin coal seam is lower.The exploitation forward comprehensive mechanization future development of present girdle, and the mining type of ultra-thin coal seam is mainly Pu Cai and big gun is adopted, energy recovery ratio and production efficiency are low.Its main cause is that existing fully-mechanized mining equipment can not satisfy ultra-thin coal seam to the requirement of mining height.
Existing drag conveyor and coal-winning machine matching method are at drag conveyor walking track or draw-gear and the guiding device that coal-winning machine comes and goes to be set, so that coal-winning machine comes and goes coal cutting.
The drag conveyor of at present girdle comprehensive mining use, its rack rails are arranged in the baffle plate outside of intermediate channel, i.e. old man's side.The running wheel of coal-winning machine also is arranged in old man's side, and the transmission of coal-winning machine just need to cause the fuselage height relatively high from the rib side to old man's side across arranging a series of transmission devices like this, is not suitable for the work plane of coal seam thickness below 0.8 meter and uses.Research and development fuselage height fully-mechanized mining equipment low, dependable performance has become the key that solves the ultra-thin coal seam mining problem.
The utility model content
In order to overcome above defective, the height of compression coal excavation apparatus, satisfy simultaneously the needs of coal work, the utility model discloses a kind of single face rack rails drag conveyor for the exploitation ultra-thin coal seam, to be arranged on rib one side for the draw-gear for the coal-winning machine walking, to cancel across a series of transmission devices in the drag conveyor upper end.
A kind of single face rack rails drag conveyor for the exploitation ultra-thin coal seam of the present utility model is arranged on the coal-winning machine below, and the front side is coal-face, and rear side is old man's side; Formed by head driving section 1, intermediate channel 7, tail driving section 2 and scraper chain, be furnished with shovel plate mechanism in intermediate channel 7 coal-faces one side, arrange waste rock board 3 in intermediate channel old man side; Intermediate channel is made of the baffle 8 of shovel board ledge 6 and baffle plate side.Be provided with rack rails 5 at shovel plate mechanism, for the coal-winning machine walking; Be provided with coal-winning machine guiding device 9 in the baffle side, be used to coal-winning machine walking guiding; Rack rails 5 comprises the riser 15 and locating piece 14 of panel and panel below, is provided with tooth 16 in a side of riser 15, and opposite side has hook 13; Shovel plate mechanism comprises the shovel board ledge 6 of shovel board 4 and shovel board rear end, the hangers 10 on the shovel board ledge, the rack rails holder 11 on the shovel board; Also be provided with fixture block 12 on the shovel board, with the hook 13 mutual buckles on the rack rails; The locating piece 14 of rack rails is fastened on the hangers 10 of shovel board ledge.
On the rack rails riser and on the rack rails holder pin-and-hole is set all, by pin or screw rack rails is fixed on the shovel board.
Beneficial effect:
Rack rails of the present utility model is by the mutual buckle of fixture block on hook and the shovel board, and the hangers of the locating piece of rack rails and shovel board ledge fastens, and so that rack rails is entered the location, its locate mode is simply effective, easy disassembly and maintenance.
The utility model cooperates the walking of coal-winning machine walking gear with rack rails, and rack rails is arranged near on the shovel board of coal-winning machine, has cancelled across a series of transmission devices in the drag conveyor upper end, has reduced the height of coal excavation apparatus, is more suitable for ultra-thin coal seam.
The utility model is provided with coal-winning machine guiding device 11 in the baffle side, is used for coal-winning machine walking guiding, can play the effect of balance coal-winning machine.
It is more approaching that coal-winning machine center of gravity and walking drive supporting point position, during work, can effectively solve the coal-winning machine driving wheel with the rack rails card bumps problem, and coal-winning machine operates steadily reliably at scrapper conveyor, is difficult for cause damage of equipment and initiating failure, is beneficial to raising coal mining efficient.
Description of drawings
Fig. 1 is drag conveyor structure chart of the present utility model;
Fig. 2 is the drag conveyor schematic cross-sectional view;
Fig. 3 is the utility model blade structure figure;
Fig. 4 is the utility model rack rails structure chart.
The specific embodiment
Preferred embodiment be that rack rails 5 and guiding device 9 are individual components, can be easily from intermediate channel 7 dismountings and installation, the rack rails that more renews after the damage gets final product, and needn't change whole intermediate channel, has saved cost of production, has improved production efficiency.
After rack rails 5 is dismantled, can supporting girdle and in the coal-winning machine of thick inclined to one side girdle use.Realized a machine polygamy, a tractor serves several purposes for coal production has been saved cost, has also made things convenient for the management of equipment.
As shown in the figure, complete single face rack rails and the guiding device installed again later of intermediate channel assembling.
The mounting method of rack rails is as follows:
At first rack rails is placed in parallel in shovel board ledge 6 outsides, then two locating pieces 14 on the rack rails panel is hung on the hangers 10 in the shovel board ledge outside, then with the fixture block 12 on the shovel board and the hook 13 mutual buckles on the rack rails 5,
