Anti-rotation piston movement auxiliary cylinder of a large marine application device

Abstract

The invention provides an anti-rotating piston kinematic pair barrel for a large-size marine application device. The anti-rotating piston kinematic pair barrel comprises a ducted barrel body, a work barrel body and a limiting barrel body. The end surface of the ducted barrel body, the end surface of the work barrel body and the end surface of the limiting barrel body are all provided with annular connection plates. The ducted barrel body, the work barrel body and the limiting barrel body are coaxially connected and fixed in sequence by fixing the annular connection plates through sets of bolts. A center guide shaft penetrates through the circle center position of the ducted barrel body and the circle center position of the limiting barrel body, and the ducted barrel body and the limiting barrel body are fixed through the center guide shaft. A plurality of limiting shock-absorbing seats uniformly distributed along a circumference are fixed to the end surface, close to one end of the work barrel body, of the limiting barrel body. According to the anti-rotating piston kinematic pair barrel for the large-size marine application device, the center guide shaft is used for positioning, so that the operation resistance of a work chamber piston can be well reduced; and accordingly, the piston can be better protected from colliding with the barrel bodies, and the reliability performance and the anti-corrosion performance of a piston kinematic pair in sea water are improved.
