摘要
超前支护替棚支架是煤矿井下液压支架技术的延伸和发展,主要用于解决煤矿井下受采动影响超前支护段顶板的维护问题。ZT9200/19/35超前支护替棚支架工阻大,结构简单、适应性强。采用四连杆机构,并且布置在两立柱中间,顶梁受力效果好,并能承受一定的水平力、侧向力。
Advance support for the shelf bracket is a coal mine hydraulic extension and development of stent technology is mainly used to address the impact of mining coal mine subject to paragraph ahead of supporting the roof of the maintenance issues. ZT9200/19/35 advance support for the shelf supports public resistance large, simple structure, strong adaptability. Use of four-bar linkage, and the two column layout in the middle of the top beams good effect, and can withstand a certain level of force, lateral force.
