Detailed Description
The present invention will be further described with reference to the following specific examples.
The invention provides a double-piston symmetric hydraulic oil cylinder device, which comprises a seat plate frame connecting plate 3, a left and right tilting oil cylinder 5, a left and right tilting shaft 6, a left oil pipe 7 and a right oil pipe 8, wherein a connecting piece 4 vertically extends out of one side of the seat plate frame connecting plate, a round hole is formed in the middle of the connecting piece 4, the left and right tilting oil cylinder 5 is provided with a round hole, one end of the left and right tilting shaft 6 sequentially passes through the connecting piece and the round hole of the left and right tilting oil cylinder 5 and is fixed in the left and right tilting oil cylinder 5, the other end of the left and right tilting shaft 6 extends out of the round hole of the connecting piece 4; the outside both ends of controlling the hydro-cylinder 5 of inclining are the symmetry respectively and are set up left side oil pipe 7 and right side oil pipe 8, set up drive welding block 9, piston 10 in the hydro-cylinder 5 of inclining about, both sides are the symmetry respectively and are set up piston 10 in the hydro-cylinder 5 of inclining about, drive welding block 9 is connected with the one end of controlling the axle 6 that inclines. The left and right tilt cylinders 5 are provided with cylinder covers 11.
The right side oil pipe 8 is used for injecting oil into the right side cavity of the left and right tilting oil cylinders 5, meanwhile, the oil in the left side cavity of the left and right tilting oil cylinders 5 is discharged through the left side oil pipe 7, the double pistons 10 can move leftwards relative to the left and right tilting oil cylinders 5 under the action of hydraulic pressure, and the drive welding blocks 9 are pushed to rotate relatively to enable the seat plate to tilt leftwards around the left and right tilting shafts 6. Through 7 oiling of left side oil pipe to 5 left side intracavity of heeling hydro-cylinder, the oil of 5 right side intracavity of heeling hydro-cylinder goes out oil through right side oil pipe 8 simultaneously, and double piston 10 can move left relatively heeling hydro-cylinder 5 under hydraulic effect, promotes drive welding block 9 relative rotation and makes the 3 right inclinations of bedplate frame connecting plate round the axle 6 that heels about.
