Abstract
The utility model relates to a seven-channel hydraulic rotary connector, which comprises a rotary piece (1) and a rotary shaft (2). The seven-channel hydraulic rotary connector is characterized in that the rotary shaft (2) consists of an upper pipeline connecting section (2.1) and a lower mounting section (2.2), the lower mounting section (2.2) is axially inserted into the rotary piece (1) from the upper end of the rotary piece (1), the upper pipeline connecting section (2.1) is exposed out of the rotary shaft (1), seven main oil channel holes are axially disposed on the rotary shaft (2), openings at upper ends of the seven main oil channel holes are distributed on the circumferential surface of the upper end of the rotary shaft (2), and seven main oil ports are radially disposed on the rotary piece (1) and used for being communicated with the seven main oil channel holes on the rotary shaft (2) in a one-to-one correspondence manner. The seven-channel hydraulic rotary connector is larger in rotation angle, avoids interference among pipelines, and is quite convenient in both operation and maintenance.
Description
Technical field
The utility model relates to a kind of seven passage hydraulic gyration joints, being mainly used in the hydraulic system of machineries such as large-tonnage excavator, hoist, grader, tower crane, is to connect standing part and the hydraulic pipe line of rotating part and the link of circuit in whole hydraulic system and the circuit.
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, the Operation and maintenance inconvenience, also interfere easily between the pipeline, cause the pipeline life-span shorter.
Summary of the invention
The purpose of this 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 easily.
The purpose of this utility model is achieved in that
The utility model seven passage hydraulic gyration joints, comprise solid of rotation and turning axle, described turning axle is made up of upper pipeline linkage section and following construction section, described construction section down inserts in the solid of rotation from the top axial of solid of rotation, described upper pipeline linkage section is exposed to solid of rotation, be provided with back-up ring and circlip for shaft between the lower end of the lower end of described solid of rotation and following construction section, rotating seal ring and O type circle I are housed in the annular groove between described solid of rotation and the following construction section, described turning axle axially offers seven working connection holes, the upper end open in described seven working connection holes is distributed on the upper end circumferential surface of turning axle, the bottom in described seven working connection holes is plugged with steel ball, the lower end port in described seven working connection holes is provided with screw plug, radially have on the described 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 effects of the utility model are:
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 can rotate 360 ° relatively with rotating part, the Operation and maintenance inconvenience just can not interfere between the pipeline, makes that the pipeline life-span is longer.And this swivel coupling provides multichannel oil circuit and multiplex circuit, makes excavator, loader can carry out the action of more complexity, has improved its applicability.
