ZTF11520/23/32型端头支架的改进

ZTF115 2 0 / 2 3/ 32型放顶煤端头支架因受转载机机尾安装条件和后输送机机头位置限制 ,放“三角煤”效果很差 ,远未达到设计要求 ,且端头架前每次替换套棚所使用的大量坑木无法回收 ,材料浪费严重。经过近三年时间的现场探索 ,提出了在尾梁上开设放煤窗口 ,由低位放煤改为中低位放煤 ,在端头架前增设活动顶梁的改进方案 ,达到了提高放“三角煤”煤量和安全可靠回收木抬棚的目的

Improvement of ZTF11520/23/32 End Support

ZTF11520/23/32 caving end support is affected by install condition of reloader end and place limit of conveyor head,"triangle caving" can′t get good result and designed demand,when head support replace shed,used wood can′t be retrieved,material is wasted.Through research about three years,this paper raises placing caving window on end beam,low caving changed,middle-low caving ,movable roof is established before head support,it gets purpose for improving "triangle caving" output and wood shed safely retrieved.
