ZZ5300/14/28型液压支架是支撑掩护式液压支架,现有一批该支架要在倾角大于20°的采煤工作面使用,由于原设计结构不能满足该大倾角采煤工作面的使用要求,笔者对该支架进行了改造设计,使其能够达到使用要求。1底调防倒、滑系统改造为防止液压支架在采煤工作面滑动,增加了底调千斤顶和底调梁,并对其连接的配套装置进行改造,底调千斤顶安装在底座内,活塞杆端与底座用卡板固定,液压缸底与底调梁中间位置连接,底调梁另一端与底座前段焊接耳板通过销轴连接。工作时,底调千
The ZZ5300 / 14/28 hydraulic support is a supporting hydraulic support, and the existing batch of support is to be used on the coal mining face whose dip angle is more than 20 °. Since the original design structure can not meet the requirements of the coal mining face with large dip angle, The author of the stent has been transformed to design, so that it can meet the requirements. 1 down-tilt prevention, sliding system transformation to prevent the hydraulic support sliding in the coal mining face, an increase of bottom jacking and bottom beam adjustment, and its connection to the matching device to be modified, bottom jack jack installed in the base, the piston rod end And the base is fixed with a card board, the bottom of the hydraulic cylinder is connected with the middle position of the bottom beam, and the other end of the bottom beam is connected with the welding ear plate of the front part of the base through a pin shaft. Work, the end of thousands
