针对薄煤层综采工作面液压支架抬底千斤顶机构行人踏板突出影响行人安全的问题,设计一种新型的薄煤层液压支架抬底机构。该液压支架抬底机构结构简单、可靠,抬底千斤顶顶部与行人踏板平齐设计,人行踏板为聚氨酯材料,有效地保证了综采工作面的作业环境和行人通道的安全。 Aiming at the problem of pedestrian safety that pedestrian pedal of hydraulic support jacking mechanism in thin coal seam fully mechanized coal mining face prominently affects pedestrian safety, a new type of hydraulic support lifting mechanism for thin coal seam is designed. The structure of the hydraulic support lifting mechanism is simple and reliable. The top of the lifting jack is designed flush with the pedestrian pedal. The pedal of the pedestrian is made of polyurethane material, which effectively ensures the working environment of the fully mechanized mining face and the safety of the pedestrian passage.
