Abstract
The utility model provides a cooling bed skirting board hydraulic control device which comprises a solenoid directional valve, a double one-way throttle valve and a hydraulic lock. A brake valve is arranged at the front end of the hydraulic lock. A sequence valve is arranged between the hydraulic lock and the brake valve. A skirting board lifting device hydraulic cylinder is arranged at the front end of the brake valve. A one-way valve is arranged at the front end of a port P of the solenoid directional valve. An energy accumulator is arranged between the port P of the solenoid directional valve and the one-way valve. A first stop valve is arranged at the front end of the one-way valve. A port A of the solenoid directional valve is connected with the sequence valve. A second stop valve is arranged at the front end of a port T of the solenoid directional valve. The port T of the solenoid directional valve is connected with an overflow valve in the brake valve. The cooling bed skirting board hydraulic control device has the advantages that the energy accumulator can guarantee that the pressure at the port P of the solenoid directional valve is stable and not influenced by movements of other oil cylinders; the brake valve can be used for prompt braking to reduce impacts; and when the solenoid directional valve breaks down, the overflow valve in one side of the brake valve can be used for overflowing. The cooling bed skirting board hydraulic control device also has the advantages of being simple in structure, convenient to maintain, energy saving, high in production efficiency and the like.
Description
Technical field
The utility model belongs to the hydraulic control field, especially relates to a kind of cooling-bed apron plate hydraulic control device.
Background technique
In the online bar collecting area cooling bed device, the skirtboard lifting is the most difficult control, the zone that rate of fault is higher: because cooling-bed apron plate uses frequent, and velocity ratio higher (300mm/s), and be multi-cylinder synchronous (mechanical connection) this just require each oil cylinder misoperation can not occur, if an oil cylinder akinesia and other oil cylinder can move then can cause spindle to twist off or oil pipe burst.As shown in Figure 2, existing cooling-bed apron plate hydraulic control device exists inaccurate to the cooling-bed apron plate hydraulic control, oil cylinder easily occurs the technical problems such as misoperation occur.
Summary of the invention
Problem to be solved in the utility model provides a kind of cooling-bed apron plate hydraulic control device, especially is suitable for the control of line Bar Cooling Bed skirtboard lifting jar.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of cooling-bed apron plate hydraulic control device, comprise solenoid directional control valve, Double throttle check valve and hydraulic lock, described solenoid directional control valve front end is provided with Double throttle check valve, described Double throttle check valve front end is provided with hydraulic lock, described hydraulic lock front end is provided with brake valve, can fast braking, reduce to impact, and when selector valve breaks down, can be by the relief valve overflow of a side, be provided with the first sequence valve between described hydraulic lock and the brake valve, this sequence valve can be adjusted the back pressure of rodless cavity, make motion steadily, described brake valve front end is provided with skirtboard lowering or hoisting gear oil hydraulic cylinder, the P port front end of described solenoid directional control valve is provided with one-way valve, be provided with accumulator between the P port of described solenoid directional control valve and the one-way valve, described one-way valve front end is provided with the first stop valve, described the first stop valve links to each other with selector valve P mouth, the A port of described solenoid directional control valve links to each other with the second sequence valve, the T port front end of described solenoid directional control valve is provided with the second stop valve, and described the second stop valve links to each other with selector valve T mouth, and described selector valve T mouth links to each other with relief valve in the brake valve.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, accumulator can guarantee the pressure stability of the P port of solenoid directional control valve, and be not subjected to the impact of other cylinder action, sequence valve can be adjusted the back pressure of rodless cavity, make motion steadily, brake valve can fast braking, reduces to impact, and when selector valve breaks down, can be by the relief valve overflow of a side; Have simple in structure, easy to maintenance, energy saving, manufacturing efficiency advantages of higher.
