顿涅茨克煤炭科学研究所研制了一种工作面端头支架。这种支架由两个可移动的支架节组成,而一个支架节位于另一个支架节的内侧。每个支架节包括顶梁1(见图,从顺槽向工作面的视图)、立柱2、带铰接杠杆4的底座3和推移千斤5。千斤顶的端部与杠杆偏心铰接,并且一端与一个支架节的杠杆连接,而另一端则与另一个支架节的杠杆连接。与杠杆的连接是用拉杆6实现的。每个支架节的底座安有杠杆回转限制器。
Donetsk Institute of Coal Science has developed a face end bracket. This bracket consists of two movable bracket sections, while one bracket section is located inside the other bracket section. Each bracket section consists of a roof beam 1 (see figure, view from slot to working face), column 2, base 3 with hinged lever 4 and push-in 5. The end of the jack is hinged eccentrically to the lever, one end of which is connected to the lever of one stand node and the lever of the other stand node on the other end. The lever is connected with the lever 6 to achieve. The base of each bracket section is equipped with a lever slew limiter.
