Description
Technical field
The utility model relates to a kind of multichannel hydraulic gyration joint, is mainly used in the hydraulic system of hoister in large tonnage, is the link that connects standing part and rotating part in the whole hydraulic system, belongs to technical field of engineering machinery.
Background technique
In the hydraulic system of hoister in large tonnage, two-part are need be rotating about it, control rotating part and the oil circuit of standing part and being connected of circuit through swivel coupling usually.Swivel coupling is made up of solid of rotation, turning axle and lid etc., and during use, the revolution lower bolster of solid of rotation and 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.
Yet generally at 50 ° to 80 °, its angle of revolution is less for the angle of swing of swivel coupling in the past, and Operation and maintenance are inconvenient, 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, and a kind of permanent pressurize is provided, and prevents that swivel coupling work the time receives one-sided oil pressure and damages, and the angle of revolution is big, and Operation and maintenance are multichannel hydraulic gyration joint easily.
The purpose of the utility model is achieved in that
The utility model multichannel hydraulic gyration joint 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, is provided with positioning plate between the upper end of said solid of rotation and the turning axle, and the lower end of said turning axle is fixed with baffle plate; The lower end of said solid of rotation is provided with end cap, and said end cap in the lower end of solid of rotation, is provided with O type circle I through screw between the lower end of said solid of rotation and the end cap; Dust ring and rotating seal ring are housed in the annular groove between said solid of rotation and the turning axle; This rotating seal ring is made up of dust blowing ring and O type circle III, and O type circle III is fixed on the dust blowing ring, and the dust blowing ring is pressed on the turning axle; Said turning axle axially offers draining hole, a center and seven working connection holes; The center of turning axle is located in draining hole, said center, the periphery in said seven working connection pore size distribution draining holes in the center, 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; The lower end port in said seven working connection holes is provided with screw plug, and the upper end port is provided with plug and O type circle II.
Compared with prior art, the beneficial effect of the utility model is:
This multichannel hydraulic gyration joint can connect the hydraulic pipe line of standing part and rotating part in the whole hydraulic system, and the solid of rotation of swivel coupling and turning axle can rotate 360 ° relatively, and Operation and maintenance are also comparatively convenient; Make that the pipeline life-span is longer, and rotating seal ring combines 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; The dust blowing ring plays the dust blowing effect; O type circle then provides pressure to the dust blowing ring, guarantees that the dust blowing ring is pressed on the turning axle, thereby can prevent effectively that swivel coupling is damaged greatly by one-sided oil pressure when working; And can long-acting pressurize, thereby have guaranteed the quality of swivel coupling.
