9- dustbands, 10- pallets, 11- spindle noses, 12- sealing rings, 13- nuts.
Specific embodiment
In conjunction with embodiment, attached drawing, the invention will be further described：
The specific embodiment of this hydraulic cylinder is described in detail referring to Figures 1 and 2.
A kind of hydraulic cylinder being used to support, the hydraulic cylinder can support vehicle and platform.By back cylinder cover 1, hydraulic fluid port A 2, piston
3rd, cylinder barrel 4, installation step 5, piston rod 6, hydraulic fluid port B 7, front end housing 8, dustband 9, pallet 10, spindle nose 11, sealing ring 12 and spiral shell
Mother 13 forms.Back cylinder cover 1 and front end housing 8 are located at the both ends of cylinder barrel 4 respectively, and piston 3 is located in cylinder barrel 4, piston rod 6 and piston 3
Contact, one end of piston rod 6 are mounted with spindle nose 11 by screw thread, and spindle nose 11 uses stainless steel material, makes 11 flexible rotating of spindle nose
Non-corrosive.Pallet 10 is connected by spherical hinge with spindle nose 11；Hydraulic fluid port A 2 and hydraulic fluid port B 7, wherein hydraulic fluid port A 2 are provided on cylinder barrel 4
Between back cylinder cover 1 and piston 3, hydraulic fluid port B 7 is equipped with erecting bed between front end housing 8 and piston 3 on 4 outer wall of cylinder barrel
Rank 5 is used to install supported body.
Piston 3 makes split type two pieces with piston rod 6, and piston 3 is fixed on by nut 13 on piston rod 6.Front end housing 8
With back cylinder cover 1 by being threadably mounted on cylinder barrel 4, piston 3 can only move between front end housing 8 and back cylinder cover 1.It is piston 3, preceding
Cylinder cap 8 and back cylinder cover 1 are equipped with sealing ring 12 and ensure that hydraulic oil will not be revealed.Front end housing 8 is equipped with dustband 9, is to protect
Shield sealing ring 12 is not destroyed by dust.
This hydraulic cylinder is fixed on by installation step 5 on vehicle and platform, past to hydraulic cylinder hydraulic fluid port A plus-pressures oily piston 3
Lower movement, piston rod 6, spindle nose 11 and pallet 10 move down together, until after pallet 10 contacts to earth, continue movement so as to change phase
Location platform height is answered, the adjustment each support hydraulic pressure cylinder piston rod extension elongation of platform can be with leveling vehicle and platform.To hydraulic pressure
Cylinder hydraulic fluid port B plus-pressures plug cock 3 up moves, and piston rod 6, spindle nose 11 and pallet 10 are withdrawn together.
It is constrained between spindle nose 11 and pallet 10 using spherical hinge, pallet 10 can be rotated around spindle nose 11 and solved due to ground not
It is flat that pallet 10 is caused to contact to earth unevenness.
This new hydraulic cylinder mainly solves the problems, such as that hydraulic cylinder bears lateral force by following two modes：
On the one hand, between piston 3 and piston rod 6 precision-fit is used using split structure between piston 3 and cylinder barrel 4,
Gap is less than 0.1mm, piston 3 is allowed to be come into full contact with cylinder barrel 4, so as to bear larger lateral force.Piston 3 uses wear-resistant material tin
Bronze and readily replaceable, intensity is less than cylinder barrel 4 (such as steel), so as to ensure that cylinder barrel 4 is not worn；And pass through nut 13
It is fixed on piston rod 6, it is readily replaceable.
On the other hand, 0.1mm is less than using precision-fit, gap between drive end bearing bracket 8 and piston rod 6, allows drive end bearing bracket 8 with living
Stopper rod 6 comes into full contact with, so as to bear larger lateral force.Simultaneously in 8 embedded seal ring 12 of drive end bearing bracket, prevent from revealing.Drive end bearing bracket 8
Using wear-resistant material tin bronze and readily replaceable, intensity is less than piston rod 6 (such as steel), so as to ensure piston rod 6 not by
It grinds away.Drive end bearing bracket 8 is readily replaceable by being threadably mounted on cylinder barrel 4.
This new hydraulic cylinder has been applied in support vehicle and platform, using showing：The device meets requirement, reliability
Height is not easy to leak, and maintainability is good, can be applied to other military projects and civilian grade product scopes, have and promote and apply well
Prospect.
