Description
Technical field
The present invention relates to the technical field of underground coal mine ultra-thin coal seam mining conveyor tool, be particularly used for the new structure of a kind of intermediate channel of ultra-thin coal seam conveyer.
Background technology
The delivered downhole equipment intermediate channel that China uses mostly is cast welding integrative-structure, this intermediate channel is by the restriction of casting ledge height dimension and supporting requirement, the three supporting automated minings of machine are difficult to realize, more ultra-thin coal seam is rejected or adopts the mode of production of hand digging and explosion coal-falling, cause that coal production and the production efficiency of China's ultra-thin coal seam are relatively low, therefore the conveyer of existing cast welding intermediate channel structure has not adapted to the exploitation of the increasingly narrower and small ultra-thin coal seam in present space, it is impossible to realize the economic goal that ultra-thin coal seam is highly efficient and productive.
It is an object of the invention to provide a kind of conveyer for ultra-thin coal seam exploitation and intermediate channel thereof, to solve the problem that existing equipment height is unsuitable for ultra-thin coal seam exploitation, it is achieved the three supporting automated minings of machine, meet the requirement of ultra-thin coal seam work surface high-yield and high-efficiency.
The technical scheme is that a kind of conveyer and intermediate channel thereof,
Described intermediate channel includes: central slot, riser, closure plate, rail chair plate, clamp, base plate, end bent plate, lateral bending plate；
Described central slot is roller welding integrative-structure, including: " mountain " type ledge, forging termination, middle plate, " mountain " type ledge is overall rolling, with forging termination, middle plate welding fabrication；
Bent plate, lateral bending plate at the bottom of the left ledge side welding of central slot of described intermediate channel.
Described intermediate channel adopts riser to weld formation pin rail seat with rail chair plate, and reverse grip pin rail coordinates installation with pin rail seat；
Further, described riser is arranged and coordinates circular hole with reverse grip formula pin rail, and closure plate is welded on riser welds mating surface side with central slot, be positioned at above mating holes；
Further, intermediate channel riser welds with on the right side of intermediate channel cell body, ledge is concordant, and rail chair plate is relative with the riser mating holes center of circle to be welded on base plate, forms pin rail seat, and reverse grip formula pin rail is arranged in the middle of riser and rail chair plate；
Further, reverse grip formula pin rail connects with straight pin after being arranged on welding rail chair, U-shaped card is inserted fixed cylinder pin in clamp (9), it is achieved the location of reverse grip formula pin rail；
The present invention also provides for a kind of conveyer, and described conveyer is provided with the conveyer intermediate channel described in any of the above-described item.
The invention have the advantage that central slot adopts roller welding integrative-structure, the structure making intermediate channel is more compact, reduce intermediate channel height itself thus reducing conveyer complete machine height, pin rail seat adopts riser and rail chair plate split Welding Structure, both the coal-winning machine requirement of strength to it had been met, can reducing again overall supporting height, the use of reverse grip formula pin rail relieves conveyer and crosses the restriction to coal-winning machine height of coal space and scraper chain road, reduces coal-winning machine self fuselage height.Intermediate channel structure of the present invention can make the supporting accomplished of conveyer and the equipment such as ultrathin seam hydraulic support, coal-winning machine, meets the economic benefit requirement of ultra-thin coal seam work surface high-yield and high-efficiency.

Detailed description of the invention
Wherein: 1, " mountain " type ledge, 2, middle plate, 3, forging termination, 4, central slot, 5, base plate, 6, rail chair plate, 7, straight pin, 8, reverse grip pin rail, 9, clamp, 10, U-shaped card, 11, riser, 12, closure plate, 13, end bent plate, 14, lateral bending plate.
The present invention provides a kind of conveyer intermediate channel, as it is shown in figure 1, central slot 4 is roller welding integrative-structure, including: " mountain " type ledge 1, forging termination 3, middle plate 2, " mountain " type ledge 1 is overall rolled structure, adopts solder technology to be welded into central slot with forging termination 3, middle plate 2.
Riser 11 shown in Fig. 2 is concordant with ledge on the right side of intermediate channel cell body 4 to be welded on base plate 5, riser 11 arranges two groups of mating holes, often group mating holes is made up of a circular hole and a slotted hole, rail chair plate 6 is provided with identical one group mating holes (as shown in Figure 4, Figure 5), during welding, the center of circle is welded on base plate 5 by riser 11 and the rail chair plate 6 circular hole center of circle, forms pin rail seat.Closure plate 12 is welded on riser 11 and welds mating surface side with central slot 4, is positioned at above mating holes.
Reverse grip formula pin rail 8 is arranged in the middle of riser 11 and rail chair plate 6, is attached with straight pin 7, clamp 9 is provided with and coordinates circular hole with U-shaped card 10, inserted in clamp 9 by U-shaped card 10, utilizes closure plate 12 and U-shaped card 10 to fix reverse grip formula pin rail.This structure replaces traditional casting rail chair, makes rail chair intensity be protected, and reduces the package size with coal-winning machine.
Bent plate, lateral bending plate at the bottom of the left ledge side welding of central slot as shown in Figure 1, simple in construction, replace the shovel board ledge of conventional cast, it is achieved the function shoveled coal.
