Introduction With the extension of the mine length of service, increase productivity, the mine39。中文 3300 字 翻譯部分 英文原文 Scalable cantilevered Development of Coal 1. abstract Scalable cantilever loaded coalmining conditions applicable to the Warehouse, the main increase Warehouse exploitation of resources recovery and reduce labor intensity of workers, to increase the safety and reliability of operations at the scene. Key words: scalable。s remaining recoverable reserves will be gradually reduced, the market petitiveness will continue to decline. In our country there are many old stateowned mine due to depleting resources, production of convergence of tension, conflict and so difficult to replace mine, a decline in production, lower benefits, the operating difficulties of the situation. In order to increase production to mitigate pressure on the operators to extend the mine life, most coal mines has increased the corners of coal, coalmining efforts. Against the mine in the coal mining corner, when the widespread use of coalmining law of the Warehouse to the characteristics of Jincheng Coal Industry Group under the Technology Center at the actual needs, through research and development applicable to the Warehouse under the conditions of exploitation of scalable with cantilevered Coal, 3. With the structure of coal Scalable cantilever loaded coal mainly by the rack, cantilever, Rotary, walking, supporting fixed, carrying bodies, hydraulic systems and other parts of position, its shape structure see Figure 1. 1 the crane 2 Doo 3 before the support of 4 emulsion winch 5 walking mechanism 6 Rotating bodies 7 control valve 8 support after 9 rack Figure 1 scalable with cantilevered structure of the coal – rack Rack is loaded coalbearing the main ponents, all ponents are installed in the rack. cantilever Cantilevered from an arm, two arms, threearm, twocylinder telescopic emulsion position, and between the turret connected with Pin. As threearm nested in the two arms, two nested in one arm arm, stretching emulsion in the secondary role of the cylinder, the cantilever stretching movements can be realized, stretching capacity of 3 670mm ~ 8 270mm. On the other hand, two fixed rotating platform of change in the role of Jack, the cantilever can achieve takeoff and landing movements, lifting capacity of: 1360 mm ~ 5 000mm. Rotary agencies Rotating bodies from the turret and fixed rack in the lower side of the two rotary jack in the rotating platform equipped with cantilever, winch and other parts of the emulsion. Rotary jack in the drive, the turret driven cantilever to do about the direction of rotation, left and right direction of the swing angle can reach 45 176。 2) by the winch, rake bucket with coal instead of the original artificial Huo coal, reducing the labor intensity of the workers。 bucket height: 1 348 mm。 climbing capacity: 16 176。 biggest walking speed: m / s。 裝煤機(jī) 。為了提高產(chǎn)量 , 緩 減經(jīng)營壓力 , 延長礦井使用壽命 , 大部分煤礦加大了對邊角煤、煤柱的開采力度。 3. 2 懸 臂 懸臂由一級(jí)臂、二級(jí)臂、三級(jí)臂、二級(jí)伸縮乳化液缸組成 , 與回轉(zhuǎn)臺(tái)之間用銷軸相連。在回轉(zhuǎn)千斤頂?shù)尿?qū)動(dòng)下 , 回轉(zhuǎn)臺(tái)帶動(dòng)懸臂做水平方向的左右轉(zhuǎn)動(dòng) , 左、右方向的擺動(dòng)角度均可達(dá)到 45176。 其特點(diǎn)是由乳化液馬達(dá)提供動(dòng)力 , 馬達(dá)額定工作壓力 12. 5M Pa
