Abstract
The utility model relates to a hydraulic revolving joint. The hydraulic revolving joint comprises a revolving body (1) and a revolving shaft (2), and is characterized in that the bottom end of the revolving shaft (2) is axially inserted into the revolving body (1) from the top end of the revolving body (1); the top end of the revolving shaft (2) is exposed out of the revolving body (1); a flange (3) is arranged between the top end of the revolving body (1) and the revolving shaft (2); a rotary seal ring (5) and a dust-proof seal ring (6) are mounted in ring-shaped grooves between the revolving body (1) and the revolving shaft (2); an upper lip (6.1) and a lower lip (6.1) are arranged on the dust-proof seal ring (6) on the side in contact with the revolving shaft (2), so as to form a double-lip port; and both the upper and the lower lips (6.1) are clung to the outer wall of the revolving shaft (2). The hydraulic revolving joint has the advantages that dust is not liable to enter into the hydraulic revolving joint; oil is not liable to spill; the revolving angle is larger; interference between pipelines is avoided; and the operation and the maintenance are very convenient.
Description
Technical field
The utility model relates to a kind of hydraulic gyration joint; Be mainly used in the hydraulic system of machineries such as large-tonnage excavator, crane, land leveller, tower crane; Be to connect standing part and the fluid pressure line of rotating part and the connector of circuit in whole hydraulic system and the circuit, belong to technical field of engineering machinery.
Background technology
Hydraulic crawler excavator, loop wheel machine, loader etc., two parts are need be rotating about it, this just exists the oil circuit of rotating part and standing part and the connectivity problem of circuit.Swivel coupling is made up of revolving body, gyroaxis and lid etc.During use, the revolution lower platform of revolving body and hydraulic crawler excavator, crane machinery is fixed, and the installing plate on the gyroaxis supports with the revolution on the revolution upper mounting plate and is connected.Hydralic hose and electric wire are installed on respectively on each hydraulic fluid port and circuit of revolving body and gyroaxis, and the upper mounting plate of hydraulic machinery then drives the gyroaxis rotation.
After yet swivel coupling in the past connects the fluid pressure line and circuit of standing part and rotating part in hydraulic system and the circuit; Standing part and rotating part relative rotation angle are generally at 50 ° to 80 °; Its angle of revolution is less; Operation and maintenance are inconvenient, also interfere easily between the pipeline, cause the pipeline life-span shorter.
And swivel coupling in the past is relatively poor with extraneous sealing performance; Extraneous dust creeps in the swivel coupling easily; Influenced the performance of swivel coupling, and the oil in the swivel coupling spills easily also, revolving body in the swivel coupling and gyroaxis are relatively rotated also produced influence; Need often oil, increase working strength of workers.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of dust be difficult for to get into, and oil is difficult for spilling, and the angle of revolution is bigger, and Operation and maintenance hydraulic gyration joint easily.
The purpose of the utility model is achieved in that
The utility model hydraulic gyration joint; Comprise revolving body and gyroaxis, insert from the top axial of revolving body the bottom of said gyroaxis, and the top of said gyroaxis is exposed to revolving body; Be provided with flange between the top of said revolving body and the gyroaxis; Be provided with the water seal circle between the bottom surface of said flange and the top of gyroaxis, the bottom of said gyroaxis is provided with base plate, and said base plate is fixed through the bottom of bolt and packing ring and gyroaxis; Rotating seal ring and dust-proof seal ring are housed in the annular groove between said revolving body and the gyroaxis; The side that this dust-proof seal ring contacts with gyroaxis is provided with up and down two lips, forms the lips mouth, should be up and down two lips all be adjacent to the outer wall of gyroaxis.
Said gyroaxis axially offers four working connection holes; The open upper end in said four working connection holes is distributed on the upper end periphery of gyroaxis; The top port in said four working connection holes is provided with screw plug head and O type circle, radially have on the said revolving body four main hydraulic fluid ports with gyroaxis on corresponding one by one being connected of four working connection holes.
Compared with prior art, the beneficial effect of the utility model is:
This hydraulic gyration joint can connect the fluid pressure line and the circuit of standing part and rotating part in whole hydraulic system and the circuit, and makes standing part and rotating part can rotate 360 ° relatively, and Operation and maintenance are inconvenient; Just can not interfere between the pipeline; Make that the pipeline life-span is longer, and dust-proof seal ring is made lips degree of lip-rounding formula, two lips about the one side that this dust-proof seal ring contacts with gyroaxis is provided with; The top and the gyroaxis of two lips fit tightly up and down; Make extraneous dust be difficult for creeping in the swivel coupling, and oil can not spill internally, thereby guarantee the performance of swivel coupling; Need not often to oil, reduced working strength of workers.
