Abstract
A support oil cylinder of a wheel excavator consists of an air discharging bolt, an oil cylinder upper cover, a shaft-used retainer ring, an O-shaped ring, an oil cylinder outer sleeve, oil cylinder supports, an inner guiding ring, a safe seal ring, an outer guiding ring, a reinforcing seal ring, a dust-proof ring, a piston rod and a support bolt. The support oil cylinder of the wheel excavator is characterized in that the oil cylinder outer sleeve is cylindrical, the oil cylinder supports are arranged on two sides of the outside of the oil cylinder outer sleeve, the oil cylinder outer sleeve is connected with the oil cylinder supports through support bolts, the oil cylinder upper cover is arranged at one end of the oil cylinder outer sleeve, the air discharging bolt is arranged at the central position of the oil cylinder upper cover, the piston rod is arranged at the central axis position of the oil cylinder outer sleeve, and the dust-proof ring is arranged at the contact position between the end of the oil cylinder outer sleeve and the piston rod. The support oil cylinder of the wheel excavator has the advantages that the support oil cylinder of the wheel excavator is provided with the safe seal ring and the reinforcing seal ring so that the safety performance of the support oil cylinder is improved, the oil leakage phenomenon is avoided, and large economic loss is also avoided simultaneously.
Description
Technical field
The utility model relates to mechanical equipment technical field, a kind of wheel excavator support oil cylinder of more specifically saying so.
Background technique
Wheel excavator for stablizing of excavator, is usually opened the supporting leg of excavator in working order down, is used for strengthening the stability of excavator; At this moment the support oil cylinder of excavator just plays crucial effects, and the support oil cylinder of existing technology generally only is provided with one seal ring, in working order down; Oil leakage phenomenon usually takes place, in case leakage of oil takes place, excavator is tilted; And the generation security incident not only influences normal manufacturing operation, also can bring bigger economic loss.
Summary of the invention
For addressing the above problem; The utility model has designed a kind of wheel excavator support oil cylinder, and its technological scheme is: described wheel excavator support oil cylinder is made up of with ring washer, O type circle, oil cylinder overcoat, cylinder bracket, interior guide ring, security seal circle, outer guide ring, enhancing seal ring, dust ring, piston rod, support bracket bolt bleeder screw, oil cylinder loam cake, axle, and it is cylindric to it is characterized in that the oil cylinder overcoat is set to; The both sides external of oil cylinder overcoat is provided with cylinder bracket; The oil cylinder overcoat is connected through support bracket bolt with cylinder bracket, and an end of oil cylinder overcoat is provided with the oil cylinder loam cake, on the central position of oil cylinder loam cake bleeder screw is set; On the central axis position of oil cylinder overcoat piston rod is set; The end of oil cylinder overcoat and piston rod contacting point are provided with dust ring, and the inboard of dust ring is provided with the enhancing seal ring, and the inboard that strengthens seal ring is provided with outer guide ring; The inboard of outer guide ring is provided with the security seal circle; The inboard of security seal circle is provided with interior guide ring, and oil cylinder loam cake and oil cylinder overcoat contacting point are provided with O type circle, and oil cylinder loam cake and piston rod contacting point are provided with axle and use ring washer.
The utility model beneficial effect is that the wheel excavator support oil cylinder is designed with the security seal circle and strengthens seal ring, has improved the Safety performance of support oil cylinder, has avoided the generation of oil leakage phenomenon, simultaneously, has also avoided bigger economic loss.
