The revolving part and the fixed part can relatively rotate for 360 degrees; the pipeline is not interfered; the upper oil channel and the lower oil channel are smooth; and the actions of all the oil channels are not linked in series.
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 machineries such as excavator, crane, land leveller, tower crane.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 large-sized machinery hydraulic central authorities swivel coupling that each oil circuit action is not connected.
The purpose of this utility model is achieved in that a kind of 5.5-7T with hydraulic pressure central authorities revolving body, comprises oil distribution seat, oil distribution shaft and end cap,
Described oil distribution shaft axially inserts in the oil distribution seat from the oil distribution seat front end, and the oil distribution shaft front end stretches out outside the oil distribution seat, and end cap is fixedly connected on the oil distribution seat rear end,
Described oil distribution shaft 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 oil distribution shaft is draining hole, center, and all the other seven peripheries that are distributed in draining hole, center are referred to as the working connection hole,
Corresponding to seven working connection holes on the oil distribution shaft, it is corresponding one by one with seven working connection holes of oil distribution shaft also to have seven main hydraulic fluid ports on the oil distribution seat.
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.Therefore be specially adapted to excavator, crane etc. and need rotating machinery.
