Zusammenfassung:The invention discloses a horizontal scissor bottom lifting mechanism. A hydraulic support base comprises a left part and a right part. The left part and the right part are connected by a bridge board, and the gap between the left part and the right part is provided with a shifting rod. The horizontal scissor bottom lifting mechanism comprises two bottom lifting frames, the middles of the two bottom lifting frames are respectively hinged to the left part and the right part, the upper ends of the bottom lifting frames are connected by a bottom lifting jack, and the lower ends of the bottom lifting frames are arranged above the shifting rod. The horizontal scissor bottom lifting mechanism is disposed on the front portion of the bridge board and solves the problem that a thin coal seam bottomlifting mechanism is small and poor in bottom lifting effect. 本发明公开了种横向剪刀式抬底机构,液压支架底座包括左部和右部,左部与右部之间通过过桥板连接,左部与右部之间的空隙部位设有推移杆,横向剪刀式抬底机构包括两个抬底顶架,两个抬底顶架的中部分别与左部和右部铰接,抬底顶架的上端通过抬底千斤顶连接,抬底顶架的下端设于所述推移杆的上方。该横向剪刀式抬底机构布置在过桥板的前部。解决了薄煤
