The hydraulic support pushing jack for the half-cutting coal mining technology comprises a common foundation and two jack suites installed on the basis of the common foundation, oil ways of the two jack suites are independent of each other, and the two jack suites extend towards the two ends with the common foundation as the center and are arranged in a straight line. The far ends of the two sets of jack suites are connecting lugs, and the two ends of the common foundation are constituent members of the two sets of jack suites respectively. According to the hydraulic support pushing jack for the half-cutting coal mining technology, half-stroke pushing and sliding and full-stroke support pulling are achieved from the structural level, and the control precision is remarkably improved.

    本发明提供了一种用于半截割采煤工艺的液压支架推移千斤顶,包括共用基础和基于所述共用基础安装的两套千斤顶套件,两套千斤顶套件的油路彼此独立,两套千斤顶套件以所述共用基础为中心向两端延伸并呈一条直线设置,两套千斤顶套件的远端为连接耳,所述共用基础的两端分别为两套千斤顶套件的组成构件。该用于半截割采煤工艺的液压支架推移千斤顶从结构层面实现半行程推溜、全行程拉架,显著提高了控制精度。
