A ring flange can be made on the retainer, and the gasket is made in the form of an annular clutch, covering the clamp and interacting with the annular flange. The connection can be provided with housings fixed on the cross, and boxes installed inside them with openings in opposite walls, inside which are installed annular elastic sleeves, and flanges are made at the inner end of the fixture, with which the annular sleeves interact, and in the back wall of each The housing has a hole. In addition, the connection can be provided with two bushings installed on both sides of the elastic sleeve and interacting with the rear body drain and flange, and it can also be equipped with power cylinders connected to one of the bushings and the box, and the box can be installed the body with the ability to move along the guides perpendicular to the axis of the cross, by means of a power cylinder mounted in the cross, and the guides are made on the side walls of the body. FIG. 1 shows the lower part of the column connected to the foundation by means of a cardan, side view} on A of FIG. 2 - cardan joint top view, top view; in fig. 3 cardan connection with the hydraulic connection of the pipe systems of the column and the foundation, axonometrics; in fig, this connection with a hydraulic connection, top view} in fig, 5 times cut A-A in fig; FIG. 6 is a section BB in FIG. 5; FIG. 7 is a cardan connection with a hydraulic connection (the second option), top view in FIG. 8, section B-B in FIG. 7, FIG. 9, section of the GTG in FIG. 7 (during installation of the box); Fig, 1 is the same in the working position of the box. The cardan joint (FIG. 1) consists of a cross 1 connecting the lower part of the oil producing column 2 with the foundation 3. On the lower part of column 2 there is a fork i, and on the foundation 3 there is a fork 5, the vertical stands of which have a pointed shape. The cross 1 (Fig. 2) along the X axis has bearings 7, each of which interacts with a trunnion 8, at the end of which a guide frame 9 is fixed, designed to facilitate the connection of the cross 1 with a fork 5 of the foundation 3. The trunnion 8 is made with an axial bore in which is placed the retainer 10 connected to the power cylinder 11.

The fixtures 10 are made with a central hole, and on the outer end of each latch 10 is fixed, for example on the thread, a head with an end sealing ring 16 interacting with the end surface of an oil pipeline 17 placed in a k or 5 plug. At the opposite end of the retainer 10, a flange 18 is fixed with bolts 19. On the outer surface of the retainer 10 there is a flange 20 with sealing rings 21, which is located in the cylinder formed by the trunnion 8, the retainer 10 and the flange 22, the flange 22 is fixed to the trunnion 8 with bolts 23, the trunnion 8 has channels 2 and 25 for supplying fluid under pressure from a power source (not shown), either along one or the other On the flange 20, stops 26 and 21 are placed on the inner surface of the trunnion 8 in the shoulder and on the end of the flange 22, limiting the axial movement of the latch 10. On the outer surface of the latch in there is a longitudinal groove 28, with which the pin 29 interacts, preventing the latch 10 from turning pins 8,
    In the first version of the cardan joint with the hydraulic connection of the column 2 with the foundation 3 (Fig.) To the inner end of the bearing 7 is fixed by bolts 30 sleeve 31, the free end of which is closed by a cover 32 with a cap 33. Elastic deformable sleeve is placed between the flange 18 and the end of the bearing 7 3, fixed at one end to the end face of the bearing 7. On the sleeve 31, there is installed a hydraulic cylinder 35, the rod of which is connected to the locking element ZB, which interacts with the stop 37, fixed by means of plates 38 to the inner surface (jwKcaTopa 10, In the sleeve) 31 a hole 39 is made, communicating its cavity with a pipe 0 fixed to the sleeve 31 by a flange. The second end of the pipe 0 is connected to the adjacent sleeve 31 of the cross t,
    In the second version of the cardan joint with the hydraulic connection of the column 2 with the foundation 3 (Fig.), The body 2 is fixed to the inner end of the bearing 7 with guides 3, made on its side surfaces, with an opening made in its rear wall and with an annular flange The SC, bolted kS to the front wall of housing 2. Inside housing 2, a jfe box is installed in the rails, in which two annular sleeves 47 and Ts8 with flanges and 50 are coaxially positioned, and the junction sleeve kj has a guide 51. elastic to 52 and w fabric 53 sleeve, and the length of the sleeve 53 is less than the sleeve 52.
    The gauge f) is fitted with hydraulic cylinders 5, interfacing with the flange 50 of the sleeve C7, which allows the size to be changed between the flanges 50 of the sleeves 7 and. At the inner end of the retainer 10 there is a flange, which is made in the form of a flange 55 with a guide sleeve 56 fixed on the end face of the retainer 10. The sleeve 56 interacts with the annular flange 4C,
    To the rear wall of the body k2, through the flange 57, the pipeline Tso is fixed, the second end of which is likewise connected to the rear wall,
    adjacent housing 2. Each box 46 is connected to the crosspiece 1 by means of a hydraulic cylinder 58 (Fig. 7, 9 and in). The guides 3 can be continued toward the hydraulic cylinder. 58 (figs. 7, 9 and 1P), by installing guides 59, one of which can be mounted on a hinge 60, which simplifies installation
    and dismantling box 46,
    To connect the oil column 2 with the foundation 3, a cross 1 is installed in the fork k of column 2, and the foundation 3 with fork 5 is installed at the bottom of the sea. The lowering is done, lines 2 with the crosspiece 1 in the sea, and the crosspiece 1 with its direction 9 frames is turned on pointed
    rack 6 forks 5.
    In the first embodiment (Fig. 3b), pressurized fluid is supplied to the channels 25 of the latches 10 located along the X axis. Each latch 10
    comes out of the axle 8 and is installed in the hole 12 of the rack 6 of the plug 5 of the foundation 3, squeezing the sleeve 3, and the sealing ring .16 pressed against the end surface of the pipeline
    17. After that, the hydraulic cylinder 35 push the locking element Zb. When the fluid in the channel 25 is depressed, the sleeve 3 presses the stop 3 to the blocking element 36. The cardan joint is ready for operation.
    The oil coming from the foundation 3 to the column 2 passes through the pipeline 1 (FIG. 3) to the retainer 10 (FIG. 5) and further to the sleeve 31,
    pipe 40, gets into the sleeve 31 of the adjacent latch 10, located along the axis Y, From latch 10, oil enters the pipeline 17 i plug 4, mounted on the column 2.
    LL of the connection of the cardan joint, the liquid under pressure is fed into the channel 24, after removing the blocking element 36 by the hydraulic cylinder 35. The latch 10 comes out of the hole 12 and the column 2 with the crosspiece 1 out of the plug 5 of the foundation 3.
