Abstract
The utility model discloses a front multi-stage hydraulic oil cylinder for an improved type dumper. The front multi-stage hydraulic oil cylinder comprises a cylinder barrel, and a carriage hinged shaft is arranged on the cylinder barrel and connected with a carriage in a hinged mode. An inner sleeve and a plunger are installed in the cylinder barrel, and a frame hinged shaft is arranged at the lower end of the plunger and connected with a frame in a hinged mode. The frame hinged shaft comprises a frame hinged shaft sleeve. A frame hinged shaft body is arranged on the two sides of the frame hinged shaft sleeve and extends transversely. A frame hinged shaft fixing device is arranged between the frame hinged shaft and the head end of the plunger. The frame hinged shaft fixing device comprises a frame hinged shaft spherical gasket which is arranged between the plunger and the upper surface of the frame hinged shaft sleeve. A spherical matching surface is arranged between the frame hinged shaft spherical gasket and the frame hinged shaft sleeve. A shaft shoulder is arranged on the plunger, the upper surface of the frame hinged shaft spherical gasket is attached to the shaft shoulder, and an oil inlet is arranged at the bottom end of the plunger.
