The swivel joint has the following beneficial effects that: the pressure of the swivel joint is maintained for a long time and the swivel joint is prevented from being damaged by oil pressure from single side during work; the fixed parts and rotating parts in the hydraulic systems and circuits can relatively rotate for 360 degrees; the actions of the oil circuits and the circuits are not cascaded; and the applicability of the hydraulic cranes is improved.
Description
Technical field
The utility model relates to a kind of swivel coupling of brushed, is mainly used in the all-hydraulic loop wheel machine of 900T level, belongs to technical field of engineering machinery.
Background technique
Two-part up and down of hydraulic pressure loop wheel machine are need be rotating, and this just exists the oil circuit of rotating part and standing part and the connectivity problem of circuit.The hydraulic gyration joint is made up of solid of rotation, turning axle and lid etc., and in use, the revolution lower bolster of solid of rotation and hydraulic pressure loop wheel machine 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.
Yet some swivel coupling had only one-sided hydraulic fluid port to carry out work in the past, 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.
And after the swivel coupling of brushed connected the hydraulic pipe line and circuit of standing part and rotating part in hydraulic system and the circuit in the past; Can not let standing part and rotating part rotate 360 ° relatively; Cause oil circuit upper and lower not smooth; Each oil circuit and circuit operation series connection cause the hydraulic pressure loop wheel machine can not carry out more complicated actions, have limited its applicability.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of permanent pressurize is provided, and prevents that swivel coupling work the time receives one-sided oil pressure and damages, and each oil circuit and circuit operation are not connected, and have improved the swivel coupling of the brushed of hydraulic pressure loop wheel machine applicability.
The purpose of the utility model is achieved in that
The swivel coupling of the utility model brushed comprises solid of rotation and turning axle, and insert in the solid of rotation from the top axial of solid of rotation the lower end of said turning axle; And the upper end of turning axle is exposed to solid of rotation, and the lower end of said turning axle is provided with baffle plate, and the below of said baffle plate is provided with brush; Said brush is provided with the brush alignment pin; Said brush connects through the lower ends of brush locating stud and turning axle, and the periphery of said brush is provided with lid, and said lid is through being bolted to the lower end of solid of rotation.
Seal ring, wear ring, rotating seal ring and dust ring are housed in the annular groove between said solid of rotation and the turning axle, and this rotating seal ring is made up of dust blowing ring and O type circle, and O type circle is fixed on the dust blowing ring, and the dust blowing ring is pressed on the turning axle.
Said turning axle axially offers eight working connection holes and draining hole, a center; The center of turning axle is located in draining hole, said center; The periphery in said eight working connection pore size distribution draining holes in the center; The termination, upper end in said eight working connection holes is all blocked with plug, radially have on the said solid of rotation eight main hydraulic fluid ports with turning axle on corresponding one by one being connected of eight working connection holes.
Compared with prior art, the beneficial effect of the utility model is:
The swivel coupling of this brushed 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; It is unimpeded that upper and lower oil circuit and circuit can keep; Each oil circuit and circuit operation are not connected, and make the hydraulic pressure loop wheel machine can carry out more complicated actions, have 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.
