ABSTRACT
The article mainly elaborated the chock shield type hydraulic support design process .The design content includes:Chooses, the system design, the main spare part design,the main spare part examination and the hydraulic system design.
The largest working resistance 0f Chock shield ZZ12000/30/50 is 12000kN/shelf,chock shield major from some following basically partial compositions: top beam, base, hydraulic legs, prop, shield beam and four linkage mechanisms. The followings are introduced in this paper: components, working principle, functions, and types of the hydraulic support; The design of each structure piece is a point. The important structure, such as ex-beam, top-beam, base, hinged pin axis and so on, are analyzed. According to its failures, affecting factors and basic considerations, the design method of the strength and stiffness of the important structure is introduced. the force analysis and strength calculation are introduced.
Keywords:The hydraulic support,four-link mechanism, structure design ; strength analysis
