    A pneumatically operated rotary power slip assembly which is mountable in a rotary drilling table. It includes a stationary housing having an annular opening therethrough adapted for mounting generally coaxially with the pipe opening in the rotary table. The stationary housing has a conduit therein for transmitting pressurized fluid. The assembly includes a rotary housing having an annular opening therethrough, which housing is adapted for mounting generally coaxially with the opening in the rotary table and for rotation therewith. The stationary housing is provided with a pair of inflatable annular seals which, together with the rotary housing, form two axially spaced apart annular ducts between said housings upon inflation of the seals. The rotary housing supports at least one generally radially extendable and retractable slip, which slip is arranged to engage a pipe inserted through the rotary housing in the radially inwardly extended position and for releasing the pipe in the radially outwardly retracted position. At least one pneumatic cylinder is mounted in the rotary housing and arranged for moving the slips radially inwardly and outwardly upon actuation thereof. Additional conduits are provided in the rotary housing for communicating with each of the aforesaid ducts and transmitting pressurized fluids to the pneumatic cylinder for operation of the aforesaid slips. The apparatus includes valve means for controlling alternate flow of fluids through the ducts to control operation of the pneumatic cylinder to move the slip radially inwardly and outwardly. There is thus provided a rotary power slip assembly which is removably inserted in a rotary drilling table wherein the pneumatic cylinder rotates with the slips such that the slips can be positioned in any position around the full circumference of the opening through the drilling table. The seal arrangement for transmitting fluid pressure to the pneumatic cylinder permits operation of the cylinder in any position, as aforesaid.

    (54) DEVICE FOR HOLDING THE PIPES ON THE TABLE OF THE DRILLING ROTOR
    base 5 of the rig. The rotary body consists of two rigidly connected elements 6 and 7 and is installed in the rotary table 8 of the rotor of the drilling rig with the help of the protrusion 9 In the rotary case there is a wedge 10 and associated with them through the steering unit 12. The element 6 The rotary body has two annular grooves 13 and 14, which communicate via channels 15. and 16, with working cavities of the control unit 12, Channels 17 and 18 are made in the fixed case, which serve to supply the working agent under pressure, which actuates the control unit 12, check valves 1E, 20 and elastic membranes 21, 22 are installed , corresponding to the annular grooves 13, 14 of the rotary body. Sealing elements 23, 24 prevent clogging of the annular gap between the stationary body 1 and the element 6 of the rotary body.
    The inverse 19, 20 (Fig. 6) have the same structures and contain the body 25 with the radial channel 26, the locking element 27 and the spring 28. The channels 17, 18 communicate with the cavities of the stationary body 1, which are covered respectively by elastic membranes 21, 22 k with the cavity 29 corresponding check valve :. The cavities of the annular grooves 13, 14 communicate with the cavity 30 of the corresponding non-return valve, through the pipe 31 through the elastic membranes 21, 22.
    The device works as follows.
    The pressure of the compressed air is transmitted through the channel 17 to the cavity 29 of the check valve 19. After that, the air pressure is transferred to the cavity j blocked by the elastic membrane 21. The membrane 21 expands radially inward to form an annular air channel with an annular groove 13 when the rotary body is in a stationary condition. As the air pressure increases above the pre-selected pressure produced by the spring 28, the locking element 27 begins to move to the right, so that the air pressure is then supplied through the cavity 30, and from there
    through pipe 31, channel 15 to the working cavity of the control unit 12, as a result of which, by means of a lever mechanism 11, the wedges 10 occupy an operating position.
    When a wedge 10 is to be withdrawn, the application of air pressure to the channel 15 is stopped and it begins to be supplied to the canal 16, as described earlier, with the result that the compressed air is supplied to the other working cavity of the control unit 12, as a result of which the wedge is diluted parties. When the air supply under pressure to the channels 17, 18 stops. C, the spring 28 feeds the locking element 27, to the left (Fig. 6); as a result, air is released. / from the working cavities of the control unit 12, as well as from the cavities j blocked by elastic membranes 21, 22.
