Abstract
The utility model discloses an oil cylinder which can work via a rod cavity; the utility model comprises a cylinder body, a cylinder cover, an end cover, a cylinder bottom, a piston rod and a piston; the piston is fixed on the piston rod through a pad sheet at the end part of the piston rod, a pressing ring bolt and a circle screw, when the utility model is operated, the pressing ring bolt is pressed and not fractured, the service life of the oil cylinder is enhanced, and the utility model is suitable for the use on a cast steel slide water port.
Description
The utility model belongs to hydraulic element, is specifically related to the oil cylinder that a kind of On/Off waters the steel slide gate nozzle.
Before the utility model proposes, be used for the hydraulic jack on the slide gate nozzle with rod chamber work, its piston all is that the junk ring bolt by rod chamber one side is fixed on the piston rod.During work, bolt is subjected to bigger pulling force and ruptures easily.During maintenance, after piston rod all must being pulled out, just can finish.
The purpose of this utility model is, is fixed on the piston rod with the hydraulic cylinder piston of the rod chamber work junk ring bolt by the piston rod end, overcomes the deficiency of above-mentioned oil cylinder from face.
The oil cylinder that is used on the slide gate nozzle comprises cylinder body, cylinder bottom, cylinder cap, end cap, piston rod, piston, piston in combination Sealing, piston guide ring, and piston is by pad, the pressure ring of piston rod end, and junk ring bolt, round nut are fixed on the piston rod.Because adopt reverse bolt to connect, during piston rod chamber workpiece, bolt is stressed, thereby can not rupture, and improves the working life of oil cylinder greatly.After the overburdening fracture, piston still can be worked and be put in place.
Accompanying drawing, slide gate nozzle cylinder structure diagrammatic sketch.
1-piston rod, 2-end cap, 3-cylinder cap, 4-cylinder body, 5-piston, 6-piston in combination seal, 7-piston guide ring, 8-pad, 9-pressure ring, 10-bolt, 11-round nut, 12-cylinder bottom.
Embodiment:
The round nut 11 of piston rod 1 end is with pressure ring 9 location, and the bolt 10 on the pressure ring 9 is connected with piston 5 by pad 8.
Claims (1)
1, a kind of slide gate nozzle oil cylinder, it comprises cylinder body, cylinder bottom, cylinder cap.End cap, piston rod, piston, the piston in combination Sealing, the piston guide ring is characterized in that piston is fixed on the piston rod by pad, pressure ring, junk ring bolt, the round nut of piston rod end.
