Abstract
The utility model relates to a seven-channel hydraulic rotating joint, which comprises a rotating body (1) and a rotating shaft (2). The seven-channel hydraulic rotating joint is characterized in that: the rotating shaft (2) consists of an upper pipeline connecting section (2.1) and a lower mounting section (2.2), and is axially provided with seven main oil-way holes; openings in the upper ends of the seven main oil-way holes are distributed in a circumferential surface at the upper end of the rotating shaft (2); rotating sealing rings (5) and a dustproof ring (6) are arranged in an annular groove between the rotating body (1) and the lower mounting section (2.2); one side of the dustproof ring (6) contacts the rotating shaft (2), and upper and lower lips (6.1) are arranged on the side to form a dual-lip opening; and both the upper and lower lips (6.1) are closely attached to the outer wall of the rotating shaft (2). Dust difficultly enters the seven-channel hydraulic rotating joint, and oil difficultly leaks out of the seven-channel hydraulic rotating joint; the seven-channel hydraulic rotating joint has a large rotating angle, and is convenient to operate and maintain; and interference between pipelines is avoided.
Description
Technical field
The utility model relates to a kind of seven passage hydraulic gyration joints; 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 swivel coupling in the past is relatively poor with extraneous sealability; Extraneous dust creeps in the swivel coupling easily; Influenced the performance of swivel coupling, and the oil in the swivel coupling spills easily also, solid of rotation in the swivel coupling and turning axle 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, can not interfere between the pipeline, and Operation and maintenance seven passage hydraulic gyration joints easily.
The purpose of the utility model is achieved in that
The utility model seven passage hydraulic gyration joints 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; The side that this dust ring contacts with turning axle is provided with two lips up and down; Form the lips mouth, should be up and down two lips all be adjacent to the outer wall of turning axle, 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:
This seven passage hydraulic gyration joints 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 it makes lips degree of lip-rounding formula with dust ring; The one side that this dust ring contacts with turning axle is provided with two lips up and down, and the top and the turning axle of two lips fit tightly up and down, makes extraneous dust be difficult for creeping in the swivel coupling; And oil can not spill internally; Thereby guaranteed the performance of swivel coupling, need not often to oil, reduced working strength of workers.
