Background technique
In all kinds of milling trains that existing steel-making enterprise uses, each frame all can use all kinds of oil cylinders, and such as supporting roller balancing cylinder, intermediate roll roller oil cylinder, work roll bending oil cylinder etc., these oil cylinders all can participate in the control of plate shape.Existing cylinder structure as shown in Figure 1, comprise end cap 1, sealing seat 3, v-seal 4, piston rod 5 and memorial archway piece 7, cylinder block and memorial archway piece 7 being integral structures, piston rod 5 is arranged in the cylinder block with seal ring 6 sealings, piston rod 5 tops link to each other with end cap 1 sealing with v-seal 4 by sealing seat 3, also be provided with dust-proof seal ring 2 between end cap 1 and the piston rod 5, end cap 1 is fixed on the cylinder block, and piston rod 5 tops are provided with dismounting tapped hole 8.
Because the restriction of field condition and device structure is overhauled at ordinary times when dismounting piston rod 5, is screwed into a lifting bolt usually in piston rod 5 tops dismounting tapped hole 8, stretches in the lifting bolt hole with loosening bar and slowly knocks out; Or, seek suspension centre (its suspension centre and oil cylinder piston bar center are out-of-line usually) in frame then and carry out the drawing dismounting by means of cucurbit.Before whole dismounting link, need the import and export oil pipe of oil cylinder to be removed be unloaded and drain the oil, but these oil cylinders (high-pressure system 210Kgf/cm
2) in seal ring 6, v-seal 4 cooperate quite tightly with cylinder body, cause dismounting difficulty, inefficiency, and when dismantling, can damage in-oil cylinder associated components.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of oil cylinder piston bar quick-release arrangement, and is simple in structure, can shorten the repair time, guarantee that the oil cylinder inner member can unexpected the damage and reduced maintenance cost, guaranteed repair quality.
The utility model is achieved in that a kind of oil cylinder piston bar quick-release arrangement, comprise handle, fixed bearing, setting sleeve, take out screw rod and joint, described fixed bearing is a hat, the fixed bearing base is provided with fixed hole, the fixed bearing center is provided with tapped hole, described taking-up screw rod passes the tapped hole at fixed bearing center, taking out the screw rod top links to each other with handle, taking out the screw rod bottom links to each other with joint, described setting sleeve is installed in the fixed bearing, setting sleeve and fixed bearing base are at regular intervals, and described taking-up screw flight rotation direction is opposite with the thread rotary orientation of joint.
Described fixed hole is the waist hole.
Annular is provided with five fixed holes on the described fixed bearing base, wherein four fixed holes be arranged in the cross position, another fixed hole departs from cross position 30 degree.
The utility model oil cylinder piston bar quick-release arrangement is simple in structure, and the rational deployment of five fixed holes can adapt to the oil cylinder demand of position, multiple hole; Take out the opposite threads of screw rod and joint, joint gets loose when preventing to dismantle piston rod; Can shorten the repair time, guarantee that the oil cylinder inner member can unexpected the damage and reduced maintenance cost, guaranteed repair quality.
