Abstract
The utility model provides a novel overload protection system of a cone crusher, which is characterized by comprising a hydraulic cylinder, an oil pipe and an overflow valve, wherein the hydraulic cylinder comprises a cylinder barrel, a piston and a piston rod; the piston rod passes through the top part of the cylinder barrel; the lower end of the piston rod is fixedly connected with the piston; the piston is movably sleeved in the cylinder barrel; the cylinder barrel is divided into a rod cavity and a rodless cavity by the piston; the rod cavity and the rodless cavity are communicated through the oil pipe; and the overflow valve is arranged on the oil pipe adjacent to the rodless cavity. The novel overload protection system of the cone crusher, provided by the utility model, has the advantages of reasonable structure and lower cost; and by arranging the overflow valve, the corresponding speed is faster when the overload pressure is released.
Description
Technical field
The utility model relates to a kind of overload protective device, the novel overload protective device of a kind of specifically gyratory crusher.
Background technology
Gyratory crusher is applicable to metallurgy, builds, builds the road, the fragmentation of raw material in chemistry and the silicate industry, is fit to broken medium hardness above various ores and rock, and gyratory crusher is when operation; Possibly have non-broken thing and infiltrate in the crusher chamber,, can cause major injury gyratory crusher like untimely eliminating; The present gyratory crusher pressure of accumulator when discharging overload that is widely used when infiltrating non-broken thing in the crusher chamber, supports that course increases in the hydraulic chamber of broken awl; Surpass the pressure of gas in the accumulator, cause accumulator to be compressed, this moment, oil flow to accumulator on one side from hydraulic chamber; Broken awl descends automatically, and non-broken thing is discharged.After fixing a breakdown, accumulator feeds back in the hydraulic chamber oil, and disintegrating machine just automatically reverts to the position of original operate as normal.But because accumulator air bag pressure in compression process can raise, stressed also possibly moment to occur excessive, and the protection to equipment during overload is not good.
The utility model content
The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and provides a kind of gyratory crusher novel overload protective device.
The utility model is the deficiency that solves the problems of the technologies described above; The technical scheme that is adopted is: the novel overload protective device of a kind of gyratory crusher is characterized in that: comprise hydraulic cylinder, oil pipe and overflow valve, said hydraulic cylinder comprises cylinder barrel, piston, piston rod; Piston rod is located in the cylinder barrel top; Piston-rod lower end is fixedly connected with piston, and piston is movably set in the cylinder barrel, and piston is divided into rod chamber and rodless cavity with cylinder barrel; Rod chamber and rodless cavity are communicated with through oil pipe, and overflow valve is arranged on the oil pipe near the rodless cavity place.
The utility model is rational in infrastructure, and cost is lower, and through the setting of overflow valve, corresponding speed is faster in the time of making the release overload pressure.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model hydraulic cylinder structure sketch map.
Mark among the figure: 1, hydraulic cylinder, 2, oil pipe, 3, overflow valve, 4, cylinder barrel, 5, piston, 6, piston rod, 7, rod chamber, 8, rodless cavity.
The specific embodiment
As shown in the figure: the novel overload protective device of a kind of gyratory crusher, comprise hydraulic cylinder 1, oil pipe 2 and overflow valve 3, said hydraulic cylinder 1 comprises cylinder barrel 4, piston 5, piston rod 6; Piston rod 6 is located in cylinder barrel 4 tops; Piston rod 6 lower ends are fixedly connected with piston 5, and piston 5 is movably set in the cylinder barrel 4, and piston 5 is divided into rod chamber 7 and rodless cavity 8 with cylinder barrel 4; Rod chamber 7 is communicated with through oil pipe 2 with rodless cavity 8, and overflow valve 3 is arranged on the oil pipe 2 near rodless cavity 8 places.When occurring the overload phenomenon in the course of work, overflow valve 3 is opened, and hydraulic oil gets into rodless cavity 8 from rod chamber 7, and oil inlet pipe need not design very thick, because the pipeline distance is shorter, resistance is little, so response speed is fast than alternate manner again.
