Abstract
The utility model discloses an electrohydraulic dual-purpose multichannel central revolving joint which comprises a central revolving joint part and a collector ring, wherein the central revolving joint part comprises a revolving body and a revolving shaft; the revolving shaft is inserted into the upper end of the revolving body, and protrudes out of the lower end of the revolving body; a plurality of channels are formed in the revolving shaft; the collector ring comprises a collector ring rotor and a collector ring stator; the upper end of the collector ring rotor is connected with a connecting seat; the upper end of the connecting seat is fixed at the lower end of the revolving body by a bolt; and the collector ring stator is connected with the revolving body by a fixed rod. With the adoption of the central revolving joint, hydraulic pipelines and electrical lines of fixed parts and rotating parts of a whole hydraulic system and an electrical system can be connected, and when the fixed parts and the rotating parts are in a counterrotating mode, the pipelines and the lines are free from interference, upper and lower oil ways and circuits are kept unblocked, and movements of each oil way and each circuit are not connected in series.
Description
Technical field
The utility model relates to the dual-purpose multichannel of a kind of electric liquid central authorities swivel coupling, being mainly used in the hydraulic system of self-propelled aerial working car, is to connect standing part and the hydraulic pipe line of rotating part and the link of electric wiring in whole hydraulic system and the electrical system.
Background technique
The self-propelled aerial working platform is a kind of staff of transporting and instrument carry out high-lift operation to specified position professional equipment, very high to safety requirement, need the data mode of car body up and down of monitoring constantly, and its up and down car body be need rotating, so just need be connected by central swivel coupling when hydraulic pipe line is connected upper body with lower body with electric wiring.Yet traditional hydraulic pressure central authorities swivel coupling can only provide the connection of top and the bottom hydraulic system pipeline, can not realize the connection of electrical system circuit.
Summary of the invention
The utility model can effectively solve the deficiencies in the prior art, and a kind of connection that both can be used for hydraulic system pipeline is provided, and can be used for the dual-purpose multichannel of the electric liquid central authorities swivel coupling of the connection of electrical system circuit again.
The technological scheme of the utility model the problems referred to above is: the dual-purpose multichannel of a kind of electric liquid central authorities swivel coupling, comprise central swivel coupling and collector ring, described central swivel coupling comprises solid of rotation and turning axle, described turning axle inserts from the solid of rotation upper end and stretches out the solid of rotation lower end, offers many passages on the turning axle; Described collector ring comprises collector ring rotor and collector ring stator, and collector ring rotor upper end is connected with connecting base, and in the solid of rotation lower end, the collector ring stator is connected with solid of rotation by fixing rod by bolt in the connecting base upper end.
Outstanding advantage of the present utility model is:
Hydraulic pipe line and the electric wiring that can connect standing part and rotating part in whole hydraulic system and the electrical system, and make when standing part is relative with rotating part to be rotated, pipeline and circuit can not interfere, and oil circuit and circuit keep unimpeded up and down, and each oil circuit and circuit operation are not connected.
Description of drawings

Be labeled as among the figure: solid of rotation 1, turning axle 2, collector ring rotor 3, collector ring stator 4, circlip for shaft 5, back-up ring 6, bearing pin 7, connecting base 8, hexagon head bolt 9, fixing rod 10, Allen bolt 11, seal ring 12, dust ring 13, O type circle 14, plug 15, O type circle 16.
Embodiment
Shown in Fig. 1-5, the dual-purpose multichannel of electric liquid described in the utility model central authorities swivel coupling is made up of solid of rotation 1, turning axle 2, collector ring rotor 3, collector ring stator 4 and connecting base 8.
Described turning axle 2 inserts solid of rotation 1 from solid of rotation 1 upper end, and stretches out solid of rotation 1 lower end, sets dust ring 13, O type circle 14, seal ring 12 between turning axle 2 and solid of rotation 1 mating face from top to bottom successively.
Described connecting base 8 usefulness hexagon head bolts 9 fixed-link are in turning axle 2 lower ends, described collector ring rotor 3 usefulness pins 7 are fixedly connected on connecting base 8 lower ends, described collector ring stator 4 is arranged at outside the collector ring rotor 3, and is fixedly connected on solid of rotation 1 lower end with Allen bolt 11 and fixing rod 10.
Because solid of rotation 1 is installed on the chassis of self-propelled aerial working car usually, turning axle 2 is installed on the revolving dial of self-propelled aerial working car usually, solid of rotation 1 and collector ring stator 4 are along with the chassis guarantees not rotate like this, going to pipeline, the circuit on chassis also guarantees not rotate, turning axle 2 and collector ring rotor then rotate along with revolving dial, and pipeline, the circuit gone to above the revolving dial are motionless relatively; In addition, the import of oil circuit and the outlet all be positioned at connecting base 8 above, the circuit import be positioned at the centre of turning axle 2 and outlet be positioned at connecting base 8 below, therefore, standing part is relative with rotating part when rotary, pipeline and circuit can not interfere, and oil circuit and circuit keep unimpeded up and down, and each oil circuit and circuit operation are not connected.
