Two pillarless mining height covering hydraulic supporter design
[Abstract]The main contents of this issue is the design of 2 pillar large mining height hydraulic support shield.
Hydraulic support is used to control the pressure of mining coal face structure. Outside mining face in the form of ballast in the hydraulic support. Hydraulic support plays an important role in today's mining work. Hydraulic support mainly from the top beam, shield beam, base, side guards, columns and various jack components. Designers should be observed support good performance, high strength, frame shift speed, safety and reliability principles.
In this design of hydraulic support, mainly in the top beam, shield beam, base, column and jack mechanical design part of the focus. Determine the size of the main components of hydraulic support structure with a common design, CAD software and then assembly drawing and part drawing. Finally, check the strength of the hydraulic support.
Upon completion of the design process, mainly the use of theoretical analysis.
