Abstract
The utility model relates to oil hydraulic cylinder technical field, particularly a kind of oil hydraulic cylinder with dust-proof cover, comprise cylinder body, piston rod and dust-proof cover, one end of dust-proof cover is fixed on cylinder body, the other end of dust-proof cover is fixing on the piston rod, also comprises compressed air gas source, dust-proof cover has exhaust check valve, compressed air gas source is blown in dust-proof cover by suction port, keeps dust-proof cover inside to be in barotropic state.The beneficial effects of the utility model are: when oil cylinder runs, no matter high-pressure air makes dust-proof cover, inner volume becomes large or diminishes, and remain barotropic state, clean high-pressure air is discharged from exhaust check valve, make dust cannot enter dust-proof cover inside, ensure that the normal operation of oil cylinder.
Description
Technical field
The utility model relates to oil hydraulic cylinder technical field, particularly a kind of oil hydraulic cylinder with dust-proof cover.
Background technique
In prior art, section hydraulic cylinder working environment very severe, except hot humid, also has the dust that a large amount of adhesion is high, the dust ring of a small amount of dust oil hydraulic cylinder itself just can be removed, but after adhesion amount acquires a certain degree, be attached to dust meeting worn piston bar and the Sealing of piston rod, cause seal failure, just need to arrange dust-proof cover, dust-proof cover does fore and aft motion along with piston rod, when piston rod stretches out, dust-proof cover internal capacity becomes large, air is entered by dust-proof cover ventilating hole, when piston rod is retracted, dust-proof cover internal capacity diminishes, air is got rid of by dust-proof cover ventilating hole, because dust is very large, when piston rod stretches out, air enters dust-proof cover inside by dust-proof cover ventilating hole, still have a small amount of dust and enter protective housing inside with air, and dust-proof cover is wrapped in piston rod, the adhesion condition of dust at piston rod cannot be seen intuitively, affect dust-proof effect
Model utility content
Technical problem to be solved in the utility model is: improve a kind of oil hydraulic cylinder with dust-proof cover, improves dust-proof effect.
The utility model solves the technological scheme that its technical problem adopts: a kind of oil hydraulic cylinder with dust-proof cover, comprise cylinder body, piston rod and dust-proof cover, one end of dust-proof cover is fixed on cylinder body, the other end of dust-proof cover is fixing on the piston rod, also comprise compressed air gas source, dust-proof cover has exhaust check valve, and compressed air gas source is blown in dust-proof cover by suction port, keeps dust-proof cover inside to be in barotropic state.
For reducing compressed-air actuated energy consumption, further restriction, compressed air gas source is connected with the control system of oil hydraulic cylinder, blows or stop blowing according to the piston rod working state control compressed air gas source of control system, only when piston rod stretches out, compressed air gas source is blown in dust-proof cover.
Further restriction, suction port is arranged on the cylinder head of cylinder body.
The beneficial effects of the utility model are: when oil cylinder runs, no matter high-pressure air makes dust-proof cover, inner volume becomes large or diminishes, and remain barotropic state, clean high-pressure air is discharged from exhaust check valve, make dust cannot enter dust-proof cover inside, ensure that the normal operation of oil cylinder.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the A place partial enlarged drawing of Fig. 1;
In figure, 1. cylinder body, 2. piston rod, 3. dust-proof cover, 4. exhaust check valve, 5. suction port.
Embodiment
As illustrated in fig. 1 and 2, a kind of oil hydraulic cylinder with dust-proof cover, comprise cylinder body 1, piston rod 2 and dust-proof cover 3, one end of dust-proof cover 3 is fixed on cylinder body 1 by anchor ear, the other end of dust-proof cover 3 is fixed on piston rod 2 by anchor ear, also comprise compressed air gas source, dust-proof cover 3 has exhaust check valve 4, compressed air gas source is blown in dust-proof cover 3 by suction port 5, dust-proof cover 3 inside is kept to be in barotropic state, clean high-pressure air is discharged from exhaust check valve 4, and dust cannot enter dust-proof cover inside, ensure that the normal operation of oil cylinder.
For saving the energy consumption of compressed air gas source, compressed air gas source is connected with the control system of oil hydraulic cylinder, blow according to the piston rod 2 working state control compressed air gas source of control system or stop blowing, dust-proof cover 3 inside is made to be in barotropic state, only when piston rod 2 stretches out, compressed air gas source is blown in dust-proof cover 3.When piston rod 2 is retracted, dust-proof cover 3 compresses, and produce malleation, the air of dust-proof cover inside is outwards vented by exhaust check valve 4, does not need compressed air gas source to blow to dust-proof cover inside.
Suction port 5 is arranged on the cylinder head of cylinder body 1, does not certainly also get rid of, and suction port can be set directly on dust-proof cover.
Claims (3)
