针对液压支架抬底机构现有技术的缺陷和不足,设计一种新型液压支架抬底机构。通过抬底千斤顶下端与推杆铰接在一起的设计,可消除抬底千斤顶与液压支架推杆之间的摩擦和磨损问题、及消除抬底千斤顶与推杆之间中介物的摩擦和磨损问题,从而提高液压支架抬底机构的使用寿命。
In view of the defects and deficiencies of the prior art of the hydraulic support mechanism, a new hydraulic support mechanism is designed. The design of the lower end of jacking jack hinged together with the push rod can eliminate the problem of friction and wear between jacking jack and hydraulic supporter push rod and eliminate the friction and wear of the mediator between jacking jack and push rod, Thus increasing the service life of hydraulic support lift mechanism.
