Abstract
The utility model relates to a level telescoping oil cylinder supporting mechanism, belonging to an oil cylinder supporting mechanism. The supporting mechanism is provided with a pedestal, shaft sleeves, a tugboat and a shaft. The tugboat is positioned on the shaft, and two ends of the shaft are connected with the shaft sleeves connected on the pedestal. The middle part of the tugboat is provided with an arc-shaped groove. The level telescoping oil cylinder is supported by the arc-shaped groove on the middle part of the tugboat, and the telescoping arm is uneasy to be distorted when the telescoping arm of the level telescoping oil cylinder stretches. The tugboat of the oil supporting mechanism is positioned on the tail of the moveable supporting leg, and when the moveable supporting leg extends, the oil cylinder always falls on the tugboat to make the moveable supporting leg in a stable telescoping, which ensures that the telescoping arm of the telescoping oil cylinder is not distorted, thereby ensuring the stable running of the level telescoping oil cylinder and improving the service life of the level telescoping oil cylinder.
Description
Technical field
The utility model relates to a kind of oil cylinder supporting mechanism, particularly a kind of horizontal telescopic oil cylinder supporting mechanism that is used for crane chassis movable supporting legs.
Background technology
Horizontal support legs is installed on Crane Truck Chassis, horizontal support legs has horizontal telescopic oil cylinder, when the telescopic boom in the horizontal telescopic oil cylinder stretches out, telescopic boom is carefully grown, and after horizontal support legs all stretched out, span was more than 4m between the telescopic oil cylinder fulcrum of two horizontal support legs, therefore make the telescopic boom distortion of horizontal support legs telescopic oil cylinder bigger, be out of shape when serious, influence the steadily flexible of horizontal support legs telescopic boom, telescopic oil cylinder is very easily damaged.
Summary of the invention
The purpose of this utility model is an on-deformable horizontal telescopic oil cylinder supporting mechanism in the time of will providing telescopic boom in a kind of horizontal telescopic oil cylinder to stretch out.
The purpose of this utility model is achieved in that this supporting mechanism has bearing, axle sleeve, tugboat and axle, and tugboat is installed on the axle, is connected with axle sleeve at two ends of axle, and axle sleeve is connected on the bearing, and the interposition of tugboat is equipped with deep-slotted chip breaker.
Beneficial effect: owing to adopted such scheme, tugboat is installed on the axle, two ends at axle are connected with axle sleeve, axle sleeve is connected on the bearing, the interposition of tugboat is equipped with deep-slotted chip breaker, horizontal telescopic oil cylinder tube is supported by the deep-slotted chip breaker of tugboat midway location, and is not yielding when the telescopic boom in the horizontal telescopic oil cylinder stretches out, and reached the purpose of this utility model.The tugboat of this oil cylinder supporting mechanism is installed in the movable supporting legs afterbody, when movable supporting legs stretches out, cylinder tube drops on the tugboat all the time, make movable supporting legs steadily flexible, the telescopic boom that has guaranteed telescopic oil cylinder is indeformable, therefore guaranteed the smooth running of horizontal telescopic oil cylinder, the service life of having improved horizontal telescopic oil cylinder.
