Description
Technical field
The utility model relates to a kind of seven passage hydraulic gyration joints of effectively pressurize; Be mainly used in the hydraulic system of machineries such as large-tonnage excavator, hoist, grader, tower crane; Be to connect standing part and the hydraulic pipe line of rotating part and the link of circuit in whole hydraulic system and the circuit, belong to technical field of engineering machinery.
Background technique
Hydraulic shovel, loop wheel machine, loader etc., two-part 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 solid of rotation, turning axle and lid etc.During use, the revolution lower bolster of solid of rotation and hydraulic shovel, hoist machinery is fixed, and the mounting plate on the turning axle 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 solid of rotation and turning axle, and the upper mounting plate of hydraulic machinery then drives the turning axle rotation.
After yet swivel coupling in the past connects the hydraulic pipe 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 some swivel coupling has only one-sided hydraulic fluid port to carry out work, can cause bigger pressure to swivel coupling is one-sided, and therefore common rotating seal ring can not effectively guarantee the swivel coupling pressure inside, thereby has influenced the quality of swivel coupling.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; A kind of permanent pressurize is provided, prevents that swivel coupling work the time receives one-sided oil pressure and damages, the angle of revolution is bigger; Can not interfere between the pipeline, and Operation and maintenance effective seven passage hydraulic gyration joints of pressurize easily.
The purpose of the utility model is achieved in that
The utility model is seven passage hydraulic gyration joints of pressurize effectively, comprise solid of rotation and turning axle, and said turning axle is made up of upper pipeline linkage section and following construction section; Said construction section down inserts in the solid of rotation from the top axial of solid of rotation; Said upper pipeline linkage section is exposed to solid of rotation, is provided with back-up ring and circlip for shaft between the lower end of the lower end of said solid of rotation and following construction section, in the annular groove between said solid of rotation and the following construction section rotating seal ring and dust ring is housed; This rotating seal ring is made up of dust blowing ring and O type circle; O type circle is fixed on the dust blowing ring, and the dust blowing ring is pressed on the turning axle, and said turning axle axially offers seven working connection holes; The open upper end in said seven working connection holes is distributed on the upper end circumferential surface of turning axle; The bottom in said seven working connection holes is plugged with steel ball, and the lower end port in said seven working connection holes is provided with screw plug, radially have on the said solid of rotation seven main hydraulic fluid ports with turning axle on corresponding one by one being connected of seven working connection holes.
Compared with prior art, the beneficial effect of the utility model is:
Seven passage hydraulic gyration joints of this effectively pressurize can connect the hydraulic pipe line and the circuit of standing part and rotating part in whole hydraulic system and the circuit; And make standing part and rotating part can rotate 360 ° relatively; Operation and maintenance are inconvenient; Just can not interfere between the pipeline, make that the pipeline life-span is longer.And this swivel coupling provides multichannel oil circuit and multiplex circuit, makes excavator, loader can carry out more complicated actions, has improved its applicability; And rotating seal ring is combined by dust blowing ring and elasticity O type circle; The O type circle of this combined type rotating seal ring is fixed on the dust blowing ring, and the dust blowing ring plays the dust blowing effect, and O type circle then provides pressure to the dust blowing ring; Guarantee that the dust blowing ring is pressed on the turning axle; Thereby can prevent effectively that swivel coupling work the time receives one-sided oil pressure big and damage, and can long-acting pressurize, thereby guarantee the quality of swivel coupling.
