【正文】 ehouse 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。 bucket height: 1 348 mm。 biggest walking speed: m / s。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。在回轉(zhuǎn)千斤頂?shù)尿?qū)動下 , 回轉(zhuǎn)臺帶動懸臂做水平方向的左右轉(zhuǎn)動 , 左、右方向的擺動角度均可達(dá)到 45176。 3. 6 行走機(jī)構(gòu) 行走機(jī)構(gòu)由軌道行走機(jī)構(gòu)和溜槽行走機(jī)構(gòu)組成。 可伸縮懸臂式裝煤機(jī)工作原理圖見圖 2。所謂倉房開采即是在采區(qū)內(nèi)先掘進(jìn)一倉體切眼 , 然后從工作面由里向外開幫挑頂 , 依次回出倉體內(nèi)的煤 , 回采工藝為 : 維修龍門口→打眼→裝藥→回棚→爆破→出煤→縮溜槽。 3) 裝煤機(jī)裝煤范圍比原來人工裝煤范圍大 , 提高了資源回收率 。 最大卸載高度 : 1 185 mm。 履帶板寬度 : 260 mm。機(jī)重 : 42 kN。 (4) 綜合配套性能好 , 機(jī)動靈活 , 適用性強(qiáng) ,可以與巷道中的其他設(shè)備 ( 如錨桿鉆機(jī)、鉆車、刮板輸送機(jī)、帶式輸送機(jī)及礦車 ) 配套使用。 (2) 電纜拖動防護(hù)問題 , 該機(jī)在運(yùn)行過程中將拖動電纜 , 目前只能設(shè)專人在機(jī)后拖動 , 尚未有更好的辦法。 (4) 裝煤機(jī)在使用過程中 , 發(fā)現(xiàn)該機(jī)的操作視線不好 , 鏟斗舉起時遮擋光線 , 燈泡電壓設(shè)計不合理 , 燈泡十分易損。 2) 鏟斗舉升后可以充當(dāng)支護(hù)工作平臺 , 便于頂板管理。如果溜子與皮帶的搭接關(guān)系處理不好 ,就會直接影響掘進(jìn)速度。 外 接油口壓力 : 16MPa。 爬坡能力 : 16176。 5) 機(jī)器在懸臂降落、自己行走、絞車動力、滾筒纏繩等方面仍有待完善。由于堆煤高度較高 , 扒煤機(jī)工作時 , 必須將吊臂伸起使吊臂頭靠近煤頂 , 才可實(shí)現(xiàn)完全裝煤。進(jìn)行裝煤工作前 , 先啟動乳化液泵站 , 將裝煤機(jī)開到靠近龍門口的合適位置 , 操作支撐固定機(jī)構(gòu)把機(jī)器固定好 , 即可以開始裝煤工作。溜槽行走機(jī)構(gòu)是為便于機(jī)器 工作時在溜槽上的移動而設(shè)計的。 3. 4 裝載機(jī)構(gòu) 裝載機(jī)構(gòu)由乳化液絞車與耙斗組成。 可伸縮懸臂式裝煤機(jī)主要由機(jī)架、懸臂、回轉(zhuǎn)機(jī)構(gòu)、行走機(jī)構(gòu)、支撐固定機(jī)構(gòu)、裝載機(jī)構(gòu)、液壓系統(tǒng)等幾部分組成 , 其外形結(jié)構(gòu)見圖 1。s attention, bucket raised at the block out light, the lamp voltage design unreasonable, the lamp is very fragile. (5) with coal in the course of operation at the scene and found the transport system must be open normally open to ensure normal production, otherwise affect production. 中文譯文 可伸縮懸臂式裝煤機(jī)的研制 可伸縮懸臂式裝煤機(jī)適用于倉房開采條件 , 主要可以提高倉房開采的資源回收率 , 減輕工人的勞動強(qiáng)度 , 增加現(xiàn)場作業(yè)的安全可靠性。 unloading the largest high: 1 185 mm。 characterized by the emulsion motor powered motor rated pressure of 12. 5M Pa, traction speed, traction 10 kN ~ 20 kN. Trailing bucket volume is cubic meters of coal loaded containers from the emulsion winch drag achieve reciprocating move
