The distance between the axes of the hinges of the thrust rod 15 is equal to the distance between the axes of the hinges of the thrust rod 16 and the distance between the axes of the hinges of the thrust rod 17. The node formed by two movable blocks 9, the frames 10 of which are interconnected t gami 15 and 16, are a deforming articulated parallelogram. In the embodiment (FIG. 4 or 9, each mobile unit is connected to two other mobile units by means of four horizontal horns t 15 and 16. Two rods 15-16 pass along one side of the 0-0 plane of symmetry of the rack, and the other two t 15-16 g - on the other side of this plane of symmetry.Movable blocks 9 are connected in pairs by means of two horizontal bars: lower 16 and upper 15. Each bar is connected by two ball joints with two movable blocks 9. In each embodiment. of the invention, the frame 10 of one of the movable blocks 9 is connected to the deck at coupling towers 18. This coupling tow 18 is connected at one end to the rakes of the movable block 9 by means of a hinge joint, and at the other end is also hingedly connected to the deck of the platform. At least one of the hinged joints is a ball joint hinge. Preferably, the coupling rod ha 18 is parallel to the thrust rods 15-17.The hinge joint, which pulls the 18 ha cable to the frame 10 of block 9, is remote from the plane of the stand. Each mobile unit 9 is equipped with additional guiding elements 19 and 20, which span the rack 3 and can guide the frame 10 of the block relative to the 0-0 symmetry plane of the block and, accordingly, the rack. These additional guide elements 19, the number of which is at least two, are conjugated with the guide track 6, parallel to the plane of symmetry of the 0-0 struts 3. The guide elements 20, the number of which is equal to at least two, are conjugate with the opposite guide track 7. Two additional guide elements 19 are coupled with track b and are located one above the other. The two directions of the xyx element 20, which are associated with track 7, are also located one above the other. In each movable block 9. there is at least one guiding element 21 coupled with the lateral direction on the track 8 of the respective support. This track 8 is perpendicular to the 0-0 plane of symmetry of the pillars 3 and cremalier. Preferably, at least two such guiding elements are mounted on the frame of one movable block. 2 The guiding elements 19-21 can, for example, be a slider or rollers. .

The deck 1 is connected to the movable blocks 9 through the suspension assembly, which includes the articulated links 22 and 23. The suspension bridge of the deck 1 contains at least two bars 24, which are directly or via intermediate elements connected to the movable blocks 9 and the deck 1. A line of vertical force passing through a hinge link 22 or 23 ka; each block 9 from the hinge suspension system and through the plane of symmetry 0-0 rack, is located at a greater distance from the K-K axis of the support than the point N applied force kremalyery (instead of the location of the equal vertical forces acting on the cremallera). In this connection, the tilting moment tends to rotate each movable block 9 around an axis, a perpendicular 0-0 pillar symmetry plane that passes through the longitudinal axis of the K-K opo. The magnitude of this moment depends on the distance d between the hinge: - connection 22 or 23 and vertical line passing through point N. In the embodiments (Figures 1-4), the deck hinge suspension system includes two rods 24, the kgs of which are vertically adjacent to the post 3. The longitudinal axis of each pole and the larnar axis 22 and 23 are located in the plane of slime 0-0 both racks. Each ha 24 is connected to the frame 10 of the block by means of the specified articulation 22, which is a ball joint and includes an axis, which is included in the structure rigidly fixed on the frame 10. It is connected to the deck 1 by means of a ball joint 25 consisting of an axis connected to the coupling part, fixed on the first pole 1. The longitudinal axis of symmetry MK., the rod passing through the axes of the hinge links 22 and 25 is located at a greater distance from the support than the plane of symmetry GG, cremalier 4 and 5 (the plane, the perpendicular on the surface of the teeth to Emaler and passing through their middle part. The torsion block 9 is affected by overturns. An instant, the magnitude of which depends on the transmitted force and on the distance d between the axis of M-M symmetry of the string 24 and the mentioned longitudinal plane of symmetry. rotate block 9 around an axis parallel to the longitudinal plane of symmetry of GG. In the embodiment (Fig. 5), the suspension assembly contains at least one ring 26. It is connected to the movable blocks 9 by means of hinged links 22 or 23, each of which is located in the plane immetrii 0-0 bar. The ring 26 is connected to (at least) two vertical rods, which pivotally connect it either to the blocks 9, or to the deck 1, or to another ring. In the embodiment (FIGS. 5 and 6), the ti of the suspender 24 is pivotally connected to the frame 10 or ring 26, which covers the support 2. This ring is connected to the blocks 9 by means of two tons of 24, and with deck 1. The hinged joints of t g 24 on the ring 26 are diametrically opposed. Swivels 24 and 27 on the ring 26 are located on diameters perpendicular to each other. In the embodiment (Figs. 7 and 8), the ring 26 is mounted above the blocks 9 and rests on the blocks 9 either by means of two articulated ball joints (links) 23 or through two strands of the suspension 24 each of which is hinged to the frame of the block 9 by means of a 22 t hinge with a ring 26. The hinge links 23 and the gi 24 are located symmetrically with respect to the plane of symmetry of the O-0 racks. The suspensions of the suspension unit 27 are pivotally connected to the ring 26 and deck 1. They are located symmetrically with respect to the K-K axis of opolet or at a right angle to the tent supports 23 or t g 24. In the embodiment (Fig. 9, the device contains three blocks 9, located around support 2, and the hinge suspension system comprises two rings 26 and 28. The ring 26 is connected to three blocks 9 by means of m t 24 suspension assemblies, whose hinge connections are in the 0-0 plane of symmetry. with ring 26 and located at an angle of 120 ° relative to each other. Ring 26 and the ring 28 is interconnected by two tons of g 27 located symmetrically with respect to the axis of the support 2. The ring 28 is connected to deck 1 with two hinges of 29 g. The hinges of g 27 on the ring 28 and the hinges of g 29 on the same ring are located on two diameters perpendicular to each other. The hinges of m 27 on the ring 26 are located on a diameter parallel to the chord connecting the hinges of two of the m g 24 on the same ring 26. In the embodiment (figure 10, each of the m g of the suspension node 24 is connected by a ball joint to a rectangular arm including a hanger. s 30 and 31, mounted on a shaft 32 located horizontally but in brackets fixed on lap 1. Both shafts 32 are parallel to each other and at an equal distance from the K – K axis, supports 2 and t r 24. Rods 31 of both levers parallel to each other. They are connected to each other by a pivotally horizontal bar 33. Such a hinge system, t g 24 with two levers, balances the forces between the two blocks 9. The device operates as follows. Gears 11 and 12 are simultaneously rotated in order to move the frame 10 of the block. Longitudinally 3. When deck 1 is floating and supports 2 are raised, the connecting rods 24 are exhausted. There are some efforts. As soon as OOE 2 is installed on the seabed, and the platform rises above ground level, the gigs 24 experience the force in the opposite direction. The tilting moments acting on the frames of the moving blocks of a single support create a force passing through the hinge joints 22 or 23. These tilting moments are quenched with the help of stop bars 15-17. Ta in the embodiment shown in Figures 1-3, when the deck 1 is pressed against the supports 2, the upper thrust 15 is tensile and the lower thrust 16 operates in compression. And n turn, when the loosened 2 is raised relative to the deck, the upper thrust ha 15 is working on compression and the lower thrust ha 16 on stretching. Due to the presence of hinges on the thrust rods 15-17 and on the coupling rod 18, each block 9 follows southward, the horizontal movements of its support 2. The coupling rod 18 does not allow the blocks 9 to rotate. The guide elements of the runners 21 facilitate the alignment of the gears 11 and 12 with respect to the rack rails 4 and 5. The guide elements 19 and 20 come into operation in the event of an imbalance in the torque balancing of the drive gears 11 and 12. The interaction between the gears 11 and the rack slats of the cremallerae 4 is balanced by the interaction between the gears 12 and the rack slats of the creamer 5. The equality of these interactions ensures the centering of each self-propelled unit relative to the corresponding rack 3. The hinge mechanism of the hanger assembly and containing one or two rings 26, 28, the movable block 9 provides the possibility of vibration following the oscillation misvoey support. This avoids overloading the gears 11 and 12 in the event that the platform is in a stationary operating state and the brakes are clamped or wedged. The lifting device can be used on supports whose racks have only one rack. It is only important that the points of application of force between the suspension unit and the blocks 9 are located in the planes of symmetry of the struts. The proposed device has a high reliability.
