支撑掩护式支架改造成掩护式支架的方法

Method to Transform Standing Shield Hydraulic Supports Shield Hydraulic Supports

为了降低生产成本,采用局部补强、近似等强度的设计原理,将支撑掩护式支架改造成掩护式支架,改造后的支架完全具备掩护式液压支架在强度方面和运行轨迹方面的要求,同时也达到了减轻支架自身的目标。

In order to reduce the expense production , by using the design principle such as locally supllying strength and approximately equi - strength, standing shield hydraulic support can be revamped as efficieatly shield hydraulic support. It not only satisified the requirement for strength and operation locus of shield hydrau- lic support, but also reach the weight of itself.
