Abstract
The utility model relates to a seven-channel hydraulic rotating connector with an electric brush, which comprises a rotating body (1) and a rotating shaft (2) and is characterized in that the rotating shaft (2) is composed of an upper pipeline connecting section (2.1) and a lower installation section (2.2). The lower installation section (2.2) is axial inserted into the rotating body (1) from the upper end of the rotating body (1), the electric brush (9) is arranged below the rotating shaft (2), and the electric brush (9) is fixed with the bottom of the rotating shaft (2) through an electric brush fixing pin (10). The upper pipeline connecting section (2.1) is exposed out of the rotating body (1), the rotating shaft (2) is axially provided with seven main oil way holes, and the rotating body (1) is radially provided with seven main oil ports to be communicated with the seven main oil way holes arranged on the rotating shaft (2) in one-to-one correspondence mode. The rotating angle of the seven-channel hydraulic rotating connector with the electric brush is large, pipelines cannot interfere with each other, and operation and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of seven passage hydraulic gyration joints of brushed; 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.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of angle of revolution bigger, can not interfere between the pipeline, and Operation and maintenance seven passage hydraulic gyration joints of brushed easily.
The purpose of the utility model is achieved in that
Seven passage hydraulic gyration joints of the utility model brushed 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, and rotating seal ring and O type circle I are housed in the annular groove between said solid of rotation and the following construction section; The below of said turning axle is provided with brush; Said brush is fixed on the brush locating stud, and said brush is fixed through the bottom of brush locating stud and turning axle, and the periphery of said brush is provided with lid; Said lid is through being bolted to the bottom of solid of rotation; Said turning axle axially offers seven working connection holes, and the open upper end in said seven working connection holes is distributed on the upper end circumferential surface of turning axle, and the bottom in said seven working connection holes is plugged with steel ball; 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 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; 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.
