掩护式液压支架近似直线机构设计方法的探讨

Discussion on Design Method of Appro ximate Linear Mechanism of Shield-type Powered Support

根据掩护式液压支架在调高过程中要求顶梁前端有近似相等的端面距的特点,将近似直线机构设计方法引用到支架的主机构设计中去,以求简化设计。

As it is required that the roof bar should have approximately equivalent face distance when the shield-type powered support is adjusting the lift,and so an approximate linear unit is designed for the main mechanism of the support for the consideration of simplification.
