Improvement of ZF9000/18/35 Hydraulic Support Repair Process
In view of the unreasonable position of the top beam and the fixed valve seat of the rear connecting rod encountered in the repair process of the ZF9000/18/35 hydraulic support used in the underground mine of Shuozhou Coal and Electricity Tiefeng Coal Industry Company,the height and number of some steel pipe clamps are unreasonable,there is a weak link in the base,and the front frame retaining pin seat is unreasonable.The direction of the hydraulic system of the support is analyzed,and the scheme of changing the position of the valve seat,welding the steel pipe clamp,welding the reinforcing bar in the weak position of the base and replacing the retaining pin seat is designed and formulated,and the field construction and effect analysis are carried out.The practice shows that the assembly efficiency is improved by 20%,the overall pipeline layout is more neat and reasonable,and the weak links of the main reinforcement outside the base are effectively strengthened.
