Technical field
The utility model relates to a kind of hydraulic cylinder travel control gear, relates in particular to a kind of stroke limit of oil hydraulic cylinder and control gear of action interlock realized in narrow space.
Background technique
At present, for the oil hydraulic cylinder of installing and using in narrow space,, so can not realize the order interlock technology of independently two-way overtravel protection and multi-cylinder because the limitation in space is difficult to be provided with the range controlling mechanism of oil hydraulic cylinder expanding-contracting action.If adopt the linear transducer control of oil hydraulic cylinder embedding structure, then its supporting soft, the hardware electrical system is very loaded down with trivial details again and cost is very high.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of oil hydraulic cylinder two-way travel control gear, is implemented in the stroke limit and action interlock of narrow space inner control oil hydraulic cylinder.
The utility model is achieved by the following technical solution: a kind of oil hydraulic cylinder two-way travel control gear, comprise oil hydraulic cylinder, the oil hydraulic cylinder inner chamber is to surround the seal chamber that forms by two end cap and cylinder barrel, piston is arranged in the hydraulic cylinder cavity, piston connects piston rod, piston rod stretches out from an end of oil hydraulic cylinder inner chamber, near in the chamber of piston rod external part cushion collar is arranged, and has oil circuit I to pass cylinder barrel on the cushion collar and is connected with outside oil circuit; The other end of oil hydraulic cylinder inner chamber has buffer cavity, has oil circuit II to be connected with outside oil circuit on the buffer cavity; The cascade column cap suitable with buffer cavity arranged on the described piston, and there is oilhole the position near buffer cavity on the described oil hydraulic cylinder internal chamber wall, connects stress pathway I in the oilhole, and stress pathway I connects pressure transducer I and external control circuit is connected; There is oilhole position near cushion collar on the described oil hydraulic cylinder internal chamber wall, connects stress pathway II in the oilhole, and stress pathway II connects pressure transducer II and external control circuit is connected.
Described stress pathway I and stress pathway II are flexible pipe.
Principle of the present utility model is, at the space-constrained adverse condition, by the original pooling feature in oil hydraulic cylinder inside, originate as signal with the significant variation in pressure of buffer stage, by the sensor acquisition signal, on pipeline, pressure relay is set the compensator or trimmer pressure signal is converted to the electrical switch signal away from the oil hydraulic cylinder installing space, then control corresponding solenoid valve on-off action in the oil hydraulic circuit, again by the deceleration of oil hydraulic circuit control oil hydraulic cylinder, stop and the order interlock.
The beneficial effects of the utility model are: gather the oil hydraulic cylinder compensator or trimmer pressure and set the electrical switch signal, realize the two-way reciprocating stroke control and the continuity reciprocation cycle of oil hydraulic cylinder in the narrow space, linear transducer travel control system than complex structure and cost costliness, have higher ease for operation and cost performance, simple in structure, reliable performance is convenient to promote and implement.
