    专利说明:

    Detailed description of the exemplary embodiment shown The rotator 10 shown in the figures comprises a stator 20 and a rotor 30. The rotor 30 rotates about an axis of rotation A.
    The stator 20 comprises an upper stator part 20a which, when using the rotator 10, is normally coupled to a working arm (not shown) or other expedient support member.
    The rotor 30 is cylindrical in construction and is arranged inside the stator 20 as shown in the figures. The rotor 30 has a protruding lower part 30a which is normally connected to a work tool or other tool to be used at a working time.
    The rotator 10 shown here is a so-called wing rotator, which means that a number of wings are arranged around the periphery of the rotor for co-operation with a adapted inner shape of the stator, wherein a liquid pressure medium, for example hydraulic oil, is used to perform the desired rotation of the rotor . Such rotors are well known and are therefore only briefly described. It will be appreciated that the rotator can, of course, be constructed in many different ways as regards the achievement of the rotational drive.
    The rotator 10 shown further comprises a swivel device 50 which includes a swivel block 60, an outer swivel tube 70 and an inner swivel tube 80.
    Fig. 2 shows the structure and function of the swivel device 40 in more detail.
    The rotor 30 has a continuous one-hole hole 31 which has different diameter ledges 31 a-d. The hollow ledge 31d supports the outer swivel tube 70, the upper end of which projects into a recess in the lower part of the swivel block 60 as shown in Fig. 2.
    The hollow ledges 31b and 31o support the inner swivel tube 80, the upper end of which projects into a recess in the lower part of the swivel block 60 as shown in Fig. 2. A first communication channel 61 for a liquid medium, for example hydraulic oil, is arranged in the swivel block 60. 61 communicates with the center hole 81 of the inner swivel tube 80 so that the liquid medium can be further communicated via the hole 31 to a tool or tool. In the embodiment shown, a communication channel 21, which communicates with the channel 61, is arranged in the upper stator part 20a to provide pressure medium communication to the swivel device 50.
    A second communication channel 62 for a liquid medium, for example hydraulic oil, is arranged in the swivel block 60, the channel 62 communicating with a ring groove 65 which in turn communicates with a gap 100 between the outer diameter of the inner swivel tube 80 and the inner diameter of the outer swivel tube 70. The gap 100 in turn communicates with a gap 101 between the hollow ledge 31c and the outer diameter of the inner swivel tube 80, which gap 101 in turn communicates with a channel 35 eccentrically arranged in the rotor shaft 30 which terminates with a ring groove 36 in the lower part of the rotor shaft 30 so the medium can be forwarded to a tool or tool. In the embodiment shown, a communication channel 22 communicating with the channel 62 is provided in the upper stator part 20a to provide pressure medium communication to the swivel device 50.
    The swivel device according to the invention thus enables a two-channel pressure medium feed-through from a fixedly arranged pressure source to a tool or tool which is supported by the rotor of the rotator.
    The swivel block 60 has at its upper end a flange portion 66 which is arranged to enable screwing of the swivel block 60 to the upper stator part 20a as shown in the figures. Within the scope of the invention, it is also possible to design the flange portion 66 with such a thickness and outer diameter that the channels 21 and 22 in the upper stator part 20a can be replaced by extended channels 61 and 62 to provide the required flow communication. It is also possible to omit the flange portion 66 of the swivel block 60 and to arrange the fixed reading of the swivel block relative to the stator part 20a by means of, for example, a reading spring or locking ring.
    Furthermore, the outer swivel tube 70 can be integrated with the rotor 30 if desired.
    It is advantageous to provide the necessary seals in the form of external ring seals 69, 79, 89 which are located in external grooves in the swivel block 60, the outer swivel tube 70 and the inner swivel tube 80. Seals arranged in this way follow when disassembling the swivel device. l / lan can, for example, choose whether the inner swivel tube should be stationary or follow the rotation of the rotor by, for example, choosing fittings and seals.
    Fig. 1 illustrates how the swivel device 50 can be easily disassembled by detaching the swivel block 60 from its anchor relative to the upper stator part 20a, after which the swivel block 60, the outer swivel tube 70 and the inner swivel tube 80 can be picked up from the rotator through an opening in the upper stator part 20. This will make it clear that service measures and component replacements will be very easy to implement.
    The invention is thus not limited to what is shown and described, but modifications and variations are of course possible within the scope of the appended claims.
