Filling scraper conveyor
Filling scraper conveyor
充填式刮板输送机
悬挂式固体瑱充刮板输达机,对于“三下”煤层开采的矿井龙为重要,通过固体填充替代了原来工作面留设的保安煤社,不仅能最大限度地提高煤炭资源的回收率,延长矿井的服务年限,滅少复杂的矸石提升环节和矸石对环境的污染,同时也避免了地面沉降塌陷的环境问题。
技术特征:
本刮板输送机主要有机头传动部、中部槽、卸料槽、伸缩机尾、刮板链等组成,具有以下特征:
1、整机弯曲性能好,垂直弯曲既要满足工作面高度的变化,又要适应液压支架移架时的降架和升架的高度变化,水平弯曲要满足液压支架移架时的推移步距的要求。
2、整机连接强度高,中部槽采用铸造槽帮和耐磨中板组焊形式,槽间采用锻造哑铃联接,满足了移架时的强度要求,减少了维修量,提高了使用寿命。
3、中部槽中板采用重叠搭接式的活动插板型式,两侧各有一个推移缸,通过推移缸控制活动插板的抽插,完成物料的填充。
4、刮板链采用中双或边双结构,圆环链采用高强度紫凑链,刮板选用高強度材料,并经整体调质加两端淬火的热处理工艺,然后又再两端堆焊耐磨层的型式,保证了刮板的强度、刚度和耐磨性,提高了刮板的使用寿命。
5、机尾是伸缩机尾,采用紧凑型液压涨紧、机械闭锁式伸缩机构,方便调整链条预紧力,保证链条处于适度张紧,使链条与链轮处于良好啮合状态,大大减少跳链和咬链事故的发生,有效提高链轮和链条的使用寿命。
Filling scraper conveyo
The suspended solid charging scraper conveyor is important for the mine dragon of "three down" coal seam mining. By replacing the original safety coal trap set on the working
face through solid filling, it can not only maximize the recovery rate of coal resources, extend the service life of the mine, eliminate complex gangue lifting links and the pollution
of gangue to the environment. At the same time, it also avoids the environmental problems of ground subsidence.
Technical features:
The scraper conveyor is mainly composed of the head drive part, the middle groove, the discharge groove, the telescopic tail, the scraper chain, etc., which has the following
characteristics:
1, the bending performance of the whole machine is good, vertical bending must meet the changes in the height of the working face, but also to adapt to the height of the
hydraulic support when moving the drop frame and lift frame changes, horizontal bending to meet the requirements of the hydraulic support when moving the step.
2, the whole machine connection strength is high, the middle groove adopts the casting groove and wear-resistant plate group welding form, the groove adopts the forged
dumbbell connection, which meets the strength requirements when moving the frame, reduces the maintenance amount, and improves the service life.
3, the middle slot plate adopts the overlapping lap type of movable insert plate type, and there is a pushing cylinder on both sides. Through the pushing cylinder, the pumping
of the movable insert plate is controlled to complete the filling of materials.
4, the scraper chain adopts double or double side structure, the ring chain adopts high-strength purple chain, the scraper adopts high-strength material, and the overall
tempering and quenching heat treatment process at both ends, and then the type of wear-resistant layer welding at both ends, to ensure the strength, stiffness and wear
resistance of the scraper, and improve the service life of the scraper.
5, the tail is telescopic tail, the use of compact hydraulic tightening, mechanical locking type telescopic mechanism, convenient to adjust the chain pretension, to ensure that
the chain is moderately tensioning, so that the chain and the sprocket are in a good mesh state, greatly reduce the occurrence of chain jumping and biting accidents, effectively
improve the service life of the sprocket and chain.
