The utility model content
The utility model provides a kind of excavator fast hydraulic pressure rotational connector, and it has solved following problem: fixed support is not generally designed in (1) existing hook inside, and only uses iron plate the sealing of hook outside weldings.Actual use and repeatedly after the fatigue test, the ratio that the connector hook appears corrupted is quite high repeatedly, had a strong impact on life of product and had the problem such as operational risk; (2) existing hydraulic quick connector install inconvenient, especially install connect more time-consuming, and the problem such as security performance is bad.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of excavator fast hydraulic pressure rotational connector, comprise housing, enclosure interior is provided with oil cylinder, the oil cylinder two ends are connected with housing with the oil cylinder axle by the assembling axle respectively, oil cylinder axle both sides are equipped with oil cylinder axle jump ring, connecting line is installed on the oil cylinder, housing one side is equipped with grapple, and housing top is provided with upper axis, and the bottom of housing is provided with fixedly tiger’s jaw, be connected with housing by the grapple axle on the grapple, the both sides of grapple axle are equipped with grapple axle jump ring, and assembling axle both sides are equipped with assembling axle jump ring, are provided with grease nipple on the grapple axle, the grapple front end is installed together by safe axle and housing, and the housing front end is provided with for the fixing safety pin of article hoisting.
Further, a kind of preferred version of the present utility model is: described safe axle is installed together by R type locating snap ring and housing.
Further, a kind of preferred version of the present utility model is: described upper axis is installed together by bolt and nut and housing.
Further, a kind of preferred version of the present utility model is: described connecting line is installed together by cassette joint and oil cylinder.
Further, a kind of preferred version of the present utility model is: the inside of described grapple is provided with main gusset plate and gripper shoe, described main gusset plate and grapple are fixed together, the junction of described gripper shoe one end and main gusset plate and grapple is fixed together, and the other end and the hook of described gripper shoe are fixed together.
Further, a kind of preferred version of the present utility model is: the two ends of described grapple axle are provided with grapple axle safety device.
The beneficial effects of the utility model:
Excavator of the present utility model fast hydraulic pressure rotational connector, main gusset plate and gripper shoe have been increased, described main gusset plate and grapple are fixed together, the junction of described gripper shoe one end and main gusset plate and grapple is fixed together, the other end and the hook of described gripper shoe are fixed together, make whole hook stressed comparatively balanced, reach the effect of reinforcing the hook main body and prolonging service life of connector.
Excavator of the present utility model is simple in structure with the fast hydraulic pressure rotational connector, oil pressure strength by excavator makes oil cylinder flexible, thereby catching bearing pin to keep stable can not fall down, adopt the artificial mode of changing compared to existing technology, install this quick connector after, only change between the supporting accessory of excavator and need 30 seconds, time saving and energy saving, also improved operating efficiency, increased in addition grapple axle safety device, its security performance is greatly improved.
