Abstract
The invention relates to the field of a scraper conveyer for mining and concretely relates to a scraper conveyer pin rail. The scraper conveyer pin rail belongs to a key functional unit of a coal mine underground working face scraper conveyer and is an operation rail of a coal cutter. Along with continuous increasing of mining coal layer thickness and slant angle, novel requirements on a coal cutter tractive force are proposed. The existing coal cutter has a tractive force of more than 2000KN and needs a pin rail corresponding to the tractive force of the coal cutter. The scraper conveyer pin rail solves the above problem, through increasing of a pin rail pitch to 176mm, the pin rail tooth sectional area is increased so that a tractive force to the pin rail is improved, and through production technology improvement, an integral die forging molding technology is adopted so that material microstructure defects are reduced and pin rail strength is guaranteed.
Description
Technical field
The present invention relates to mine flight conveyer field, specifically relate to a kind of Integral die-forged 176 pitch drag conveyor pin rail.
Background technology
At present, in coal-mine integrated-mining equipment, coal-winning machine chainless haulage is with its stability, and load is uniform, and the tractive force born is large, adapts to high inclination-angle, and in use procedure, the advantage such as easy to maintenance, has become the mainstream model of comprehensive mechanical coal mining.Wherein the application of traction wheel pin rail type chainless haulage is the most extensive.The track that pin rail is walked as coal-winning machine, subjects the tractive force that traction motor for coal mining machine passes over.Constantly thickening along with present coal mining coal seam thickness, seam inclination is increasing, and therefore shearer haulage power is also increasing, and some coal mining tractive force is greater than 2000KN.The 125 pitch pin rails used now, the pin rail of 126 pitches, the pin rail of 147 pitches, 151 pitch pin rails, the pin rail of 172 pitches all cannot meet the requirement of exploitation now.So the pin rail adapting to larger shearer haulage power becomes the problem that present drag conveyor must solve.
Patent working content
The present invention is just to provide a kind of high strength scraper conveyer pin rail adapting to shearer haulage power and be greater than 2000KN.
In order to solve the problem, the present invention includes secondary rail plate, pin tooth and backbone plate, its design feature is secondary rail plate, pin tooth, and backbone plate is coupled together by contour forging technique, and each pin tooth is in pair, and on backbone plate, equidistant parallel is arranged, the spacing of adjacent pin tooth is 176mm.
After adopting said structure, secondary rail plate, pin tooth and backbone plate adopt Integral die-forged to link together, pin tooth in-orbit on plate equidistant 176mm arrange, pitch like this by increasing pin rail improves the supporting capacity of pin rail, reduce materials microstructure defect by the technique of Integral die-forged, the stability in the pin intensity of rail and use procedure can be improved like this, can meet by above 2 measures the requirement that present shearer haulage power is greater than 2000KN.
Accompanying drawing explanation
Below by drawings and Examples, the present invention is described further
Fig. 1 is top view of the present invention
Fig. 2 is Fig. 1 main TV structure schematic diagram of the present invention
Detailed description of the invention
In FIG, pin tooth 2 is arranged according to equal pitch 176mm, and the profile of tooth of pin tooth 2 draws by engaging with the traction wheel of coal-winning machine, ensures that pin rail and shearer haulage take turns correct engagement.The hole of backbone plate 3 is used to wear pin steady pin rail.
In fig. 2, secondary rail plate 1 is parallel with backbone plate 3, pin tooth 2 and secondary rail plate 1, and backbone plate 3 is arranged vertically, and adopts round-corner transition in its coupling part, reduces stress and concentrates.Secondary rail plate 1, pin tooth 2, backbone plate 3 is by Integral die-forged one-shot forming.
Claims (2)
1. the drag conveyor pin rail of Integral die-forged 176 pitch, comprise secondary rail plate (1), pin tooth (2), backbone plate (3), its feature is exactly secondary rail plate (1), backbone plate (3) and pin tooth (2) are linked into an integrated entity by Forging Technology, and each pin tooth (2) is equidistant being arranged on secondary rail plate (1) and backbone plate (3), and the distance between adjacent pin tooth is 176mm.
2. Integral die-forged 176 pitch pin rail according to claim 1, it is characterized in that the spacing between adjacent pin tooth is 176mm, pin tooth and rail plate all adopt round-corner transition, by Integral die-forged technological forming.
