4基本构造和工作原理

4.1堆料机

堆料机主要由悬臂部分、行走机构、液压系统、来料车、轨道部分、电缆坑、动力电缆卷盘、控制电缆卷盘、限位开关装置等组成。

4.1.1悬臂部分

悬臂架由两个变截面的工字型梁构成，横向用钢板连接成整体，工字型梁采用钢板焊接成型。

因运输限制，臂架厂内分段制造，现场焊接成整体。

悬臂架上面安装有胶带输送机，胶带机可随臂架上仰16°、下俯－16°，胶带机的传动采用电动滚筒。

张紧装置设在头部卸料点处，使胶带保持足够的张力。

张紧装置采用螺旋张紧。

胶带机上设有料流检测装置，当胶带机上无料时发出信号，堆料机停机，同时还没有打滑检测器、防跑偏等保护装置。

胶带机头、尾部设有清扫器。

头部卸料改向滚筒处设有可调挡板，现场可以根据实际落料情况调整挡板角度、位置来调整落料点。

悬臂前端垂吊两个料位探测仪。

随着堆料机一边往复运动，一边堆积物料，料堆逐渐升高，当料堆与探测仪接触时，探测仪发出信号，传回控制室，控制室启动变幅液压系统，通过油缸推动悬臂提升一个预先给定的高度。

两个探测仪，一个正常工作时使用，另一个用作极限保护。

悬臂尾部设有配重箱，箱内装有铸铁及混凝土配重块。

悬臂两侧设有走台，走台上铺设热浸锌钢格板，一直通到悬臂的前端，以备检修、巡视胶带机之用。

悬臂下部设有两处支撑胶点，一处是与行走机构的门架上部铰接，使臂架可绕铰点在垂直面内俯仰；另一处是通过关节轴承与液压缸的活塞杆端铰接，随着活塞杆在油缸中伸缩，实现臂架变幅运动。

液压缸尾部通过球铰铰接在门架的下部。

为了传递横向载荷，在门架上部铰点处，设有剪力支座。

在悬臂与三角形门架铰点处，设有角度限位开关，正常运行时，悬臂在－16°～＋16°之间运行；当换堆时，悬臂上升到最大角度16°。

4.1.2行走机构

行走机构由门架和行走驱动装置组成。

门架通过球铰与上部悬臂铰接，堆料臂的全部重量压在门架上。

门架下端两侧分别与一套驱动装置铰接（驱动装置共2套）。

每套驱动装置由一台4kw的电机驱动。

驱动装置实现软启动、延时制动。

门架下部设有平台，用来安装变幅机构的液压站。

行走驱动装置采用电机－制动器－减速器－车轮系统的传动形式，驱动系统的同步运行是靠结构刚性实现的。

车轮架的两端设置缓冲器和轨道清扫器。

在门架的横梁上吊装一套行走限位装置，所有行走限位开关均安装在吊杆上，随堆料机同步行走，以实现堆料机的限位。

（关于限位开关功能的详细说明参见图纸和电气说明书。

）

4.1.3来料车

堆料胶带机从来料车通过，将堆料胶带机运来的物料通过来料车卸到悬臂的胶带机上。

来料车由卸料斗、斜梁、立柱等组成。

卸料车悬挂在斜梁前端，使物料通过卸料车卸到悬臂的胶带面上。

斜梁由两根焊接工字型梁组成，横向通过4根大立柱支撑。

大立柱之间用工字型梁联接，工字型梁和斜梁之间又支撑4根小立柱。

这样可保证卸料车的整体稳定性。

工字型梁上安装有电气柜、控制室以及电缆卷盘。

斜梁上设有胶带机托辊，前端设有卸料改向滚筒，尾部设有防止空车时飘带的压辊。

大立柱下端装有四组车轮。

卸料改向滚筒处设有可调挡板，现场可以根据实际落料情况调整挡板角度、位置来调整落料点。

来料车的前端大立柱与行走机构的门架通过绞轴联接，使来料车能够随行走机构同步运行。

4.1.4液压系统

液压系统实现悬臂的变幅运动。

液压系统由液压站、油缸组成，液压站安装在三角形门架下部的平台上，而油站支撑在门架和悬臂之间。

4.1.5电缆卷盘

动力电缆卷盘由单排大直径卷盘、集电滑环、减速器及力矩堵转电机组成。

外界电源通过料场中部电缆坑由电缆通到卷盘上，再由卷盘通到堆料机配电柜。

控制电缆卷盘由单排大直径卷盘、集电滑环、减速器及力矩堵转电机组成。

主要功能是把堆料机的各种联系反映信号通过多芯电缆与中控室联系起来。

4.2取料机

侧式刮板取料机由刮板取料系统、卷扬提升系统、机架部分、固定端梁、摆动端梁、轨道系统、导料槽、动力电缆卷盘、控制电缆卷盘等部分组成。

4.2.1刮板取料系统

刮板取料系统是本机实现取料功能的主要部分。

驱动装置通过锁紧盘联接在驱动轴上，驱动轴上的链轮带动链条及固定在链条上的刮板在悬臂架的支承下循环运转，将物料刮取到料仓一侧。

驱动装置由电机、耦合器和减速器组成，减速器为直角轴全硬齿面空心轴减速器。

臂架为两个工字形板梁中间加交错连杆的结构，梁的上、下分别布置有支承链条的轨道导槽。

在改向链轮一端设有带塔形的张紧装置，可调节链条的松紧。

链条采用套筒滚子链。

4.2.2机架及行走端梁

机架和行走端梁的作用是支承整机重量并驱动取料机在料场内的轨道上往复运行，机架采用了箱形结构的刚性平台，行走端梁由车轮组、驱动装置和支承结构梁组成，其下部可在轨道上行走，上部与机架平台一侧用螺栓刚性连接（固定端梁）。

另一侧铰链（摆动端梁）。

两套驱动装置均设在固定端梁上，构成单侧双驱动形式。

驱动装置由电机和行星摆线减速器、电磁离合器、调车电机和直交轴减速器、制动器等组成。

在取料机进行取料工作行走时，取料电机驱动车轮组，此时电磁离合器处于通电状态，即合的位置。

当调车时，由调车电机驱动车轮组，此时电磁离合器处于断电状态，即脱开状态。

注意：

一套驱动装置的两个电机不能同时处于工作状态，启动其中一台电机，另一个电机必须首先停止运行，当设备调试好后取料量的调整依靠改变行走电机的频率来实现。

4.2.3卷扬提升系统

该系统是完成刮板取料系统变幅的机构，由支承架和电动葫芦、滑轮组等组成，并带有过载保护装置。

4.2.4链条润滑系统

本机在机架的一侧设有稀有润滑站，通过油管和给油指示器将润滑油滴在链条上保证两条道路正常工作。

在正常工作情况下，要求链条每工作三小时就需润滑一次，每次润滑5分钟，每次总油量为1.25升。

4.2.5导料槽

导料槽设计有可调溜板，可根据实际落料情况调节合适的角度，保证物料准确落在出料胶带机上，导料槽内设有耐磨衬板。

4.2.6电缆卷盘

a.动力电缆卷盘由单排大直径卷盘、集电滑环、减速器及力矩堵转电机组成。

外界电源通过料场中部电缆坑由电缆通到卷盘上，再由卷盘通到取料机配电柜。

b.控制电缆卷盘由单排大直径卷盘、集电滑环、减速器及力矩堵转电机组成。

主要功能是把堆料机的各种联系反映信号通过多芯电缆与中控室联系起来。

5．工作原理

取料机在混合料场中与堆料机配合使用，混合料场由多个相邻的料仓组成，储存数种不同的物料，堆料机在料仓的一侧堆积的物料由取料机在料仓的另一侧的轨道上往复运行，通过刮板取料机卸到导料槽内，通过导料槽送到出料胶带机上运出。

取料臂每取完一层物料后，按预定的指令下降相应的高度（既相应的物料深度）并在相应的取料运行速度下，将料逐层取出，直至该料仓物料全部取净。

这种取料过程使堆料机按一定方式堆积起的物料再次得到均化。

取料时操作人员按照中控室的指令将取料机调车到指定的料仓内（注意：

本机不可与堆料机在一个料仓内工作）。

借助行走限位装置正确识别本机所处的料仓编号。

当取料机按指令调入即将取料的料仓时限定了该料仓的左右两端的行走极限位置，取料机将在该极限位置内按程序做往复取料运行。

安装在电动葫芦上的编码器可以正确控制刮板臂的下降角度，保证取料机恒定的取料能力。

在保证恒定取料能力及确定的取料速度的情况下，为使刮板之间充入设计的最大容量的物料，悬臂及刮
