Description
Technical field
The utility model relates to the central revolving body of a kind of hydraulic pressure.Be mainly used in the whole hydraulic system of the medium-sized excavator of 8-13.5 ton.Be to connect the fluid pressure line of fixing in the whole hydraulic system with rotating part.
Background technology
Hydraulic crawler excavator, crane etc., two parts are need be rotating about it, and just there is the oil circuit connectivity problem of rotating part and standing part in this, and hydraulic pressure central authorities swivel coupling is exactly to be used for connecting the fluid pressure line of fixing in the whole hydraulic system with rotating part.Before the utility model is made, conventional hydraulic crawler excavator, crane etc., two-part revolution is to adopt the traction of monotubular formula oil cylinder about it, generally at 50～80 °, the angle of revolution is little for the anglec of rotation, the operating maintenance inconvenience, pipeline interferes easily, and pipeline is short application life.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of rotating part and standing part can rotate 360 ° of pipelines relatively and does not interfere, and upper and lower oil circuit is unimpeded, the eight passage hydraulic pressure central authorities revolving body that each oil circuit action is not connected.
The purpose of this utility model is achieved in that the central revolving body of a kind of eight passage hydraulic pressure, comprises revolving body, gyroaxis and end cap,
Described gyroaxis axially inserts in the revolving body from the revolving body front end, and the gyroaxis front end stretches out outside the revolving body, and end cap is fixedly connected on the revolving body rear end,
Described gyroaxis axially offers eight oil circuit holes that the depth is different to the back-end by front end, and wherein a center that is arranged in gyroaxis is draining hole, center, and all the other seven peripheries that are distributed in draining hole, center are the working connection hole,
Corresponding to seven working connection holes on the gyroaxis, it is corresponding one by one with seven working connection holes on the gyroaxis also to have seven main hydraulic fluid ports on the revolving body.
During use, the revolution lower platform of revolving body and hydraulic crawler excavator, crane machinery is fixed, and the revolution on the revolution upper mounting plate of gyroaxis upper mounting plate and hydraulic crawler excavator, crane machinery is supported and is connected.Hydralic hose is installed on respectively on each hydraulic fluid port of revolving body and gyroaxis.The upper mounting plate of hydraulic crawler excavator, crane machinery drives the gyroaxis rotation.The whole hydraulic system of the utility model is connected with upper and lower pipeline by revolving body, makes hydraulic crawler excavator, upper and lower two parts of crane machinery have 360 ° of relative gyrations, and pipeline does not interfere, and upper and lower oil circuit is unimpeded, and each oil circuit action is not connected.And this central swivel coupling can provide the oil circuit of eight passages, not only can be for running motor provide oil circuit, and can also shovel oil cylinder oil circuit is provided for pushing away figure on this basis, make the function of excavator more comprehensive.
