Description

Technical Field

[0001] This invention relates to the field of ship support technology, and in particular to an adjustable lifting support device for ships. Background Technology

[0002] During the construction of marine engineering projects, temporary supports are frequently used during the assembly and installation of sections. The adjustable height and stability of the supports play a crucial role in the efficiency and safety of their use. Currently, the industry typically uses fixed-height piers during the assembly and installation of shipbuilding sections. This assembly and installation method results in inflexible use of piers, and the fixed height cannot meet the needs of various projects, requiring temporary elevation of the piers.

[0003] For example, a patent with publication number CN116971284A, entitled "A Pier Device for Pushing Steel Truss Bridge and Its Usage Method," published on October 31, 2023, relates to the field of bridge beam installation technology. It includes a working platform on which two pier systems are installed, with a walking machine between them. A distribution beam is installed on the top of the walking machine. The pier system comprises a bottom beam, a pier body, and a distribution beam (from bottom to top). The tops of the distribution beams are suitable for supporting the beam. This device solves the problem of manually adding or removing pads, allowing adjustment of the beam's height. However, although it solves the height adjustment problem, it was found that there is always a difference in height between the two pier systems, reducing stability. Summary of the Invention

[0020] like Figures 1 to 8 As shown, an adjustable lifting support device for ships includes a base 1, a lifting device 2 is provided in the middle of the base 1, a support 3 is provided on the lifting device 2, the lifting device 2 is used to adjust the lifting and lowering of the support 3, a limiting cylinder 6 is vertically provided above the support 3, the side wall of the limiting cylinder 6 is connected to the base 1 through multiple support frames arranged at equal angles, an adjusting column 4 is provided on the support 3 and passes through the limiting cylinder 6, a top column 5 is provided at the upper end of the adjusting column 4 for supporting the sections of the ship, a working platform 7 is connected to the support frame, the limiting cylinder 6 passes through the working platform 7, multiple receiving slots are opened at equal angles on the side wall of the adjusting column 4, the receiving slots are located above the working platform 7, a stop rod 25 is hinged in the receiving slot, the end of the stop rod 25 is hinged to the bottom of the receiving slot, a second drive telescopic rod 24 is provided above the stop rod 25 and hinged to the receiving slot, the telescopic end of the second drive telescopic rod 24 is hinged to the middle of the stop rod 25.

[0021] During the assembly of marine engineering products, in order to facilitate temporary support in sections and improve production efficiency, the jacking equipment 2 controls the adjustment of the piers 3 and the adjusting columns 4 to meet different jacking height requirements. Under the premise of ensuring safety, it is flexible to use and convenient to operate, which greatly improves production efficiency. When controlling the lifting and lowering of the adjusting column 4, the second drive telescopic rod 24 controls the rotation of the abutment rod 25. The lower end of the abutment rod 25 contacts the upper surface of the working platform 7, which helps to improve the stability of the jacking support device and also helps to reduce the probability of the adjusting column 4 tilting.

[0022] The adjusting column 4 has a lifting point 8 on its side wall, which is located above the working platform 7. The lifting point 8 is used for lifting and moving. A ladder 10 is provided on one side of the working platform 7. The ladder 10 is used for operators to climb onto the working platform 7. The lower end of the ladder 10 is connected to the base 1. The working platform 7 is surrounded by a guardrail 9. An opening door is provided on the guardrail 9, which is located above the ladder 10.

[0023] The regulating column 4 is equipped with multiple branch pipes, and two adjacent branch pipes are connected by flanges and bolts.

[0024] The lifting device 2 can be a drive cylinder, which facilitates the control of the lifting and lowering of the support 3 and the adjusting column 4 on the support 3.

[0025] Multiple inclined, visually perceptible pins 11 are provided at equal angles on the side wall of the limiting cylinder 6, through which the tilting support device can be observed.

[0026] The support frame includes an inclined support rod 12 for connecting the base 1 and the working platform 7, and a reinforcing rod 14 connected to the inclined support rod 12, with the other end of the reinforcing rod 14 connected to the limiting cylinder 6.

[0027] like Figures 3 to 8 As shown, to improve the stability of the lifting support device, an inclined support plate 13 is provided between two adjacent inclined support rods 12. The base 1 includes multiple extension support members arranged at equal angles. Each extension support member includes a side groove 19 formed on the side wall of the base 1. An extension plate 20 is slidably connected in the side groove 19. A driving member is provided on the base 1 to control the extension plate 20 to extend into and out of the side groove 19. An inclined groove 22 is formed on the upper surface of the extension plate 20. A first driving telescopic rod 23 is hinged to the bottom of the inclined groove 22. The telescopic end of the first driving telescopic rod 23 is inclined upward and points towards the limiting cylinder 6. A distance is provided between the first driving telescopic rod 23 and the limiting cylinder 6. When the inclined support plate 13 is placed and the adjusting column 4 moves upward, the driving component controls the extension plate 20 to extend out of the side groove 19, so that extension plates 20 extend on all four sides of the base 1, increasing the contact area between the lower end surface of the lifting support device and the ground. The lower end surface of the extension plate 20 is provided with an elastic pad. After the extension plate 20 extends, the first driving telescopic rod 23 extends. The telescopic end of the first driving telescopic rod 23 extends upward along the inclined groove 22. When the telescopic end of the first driving telescopic rod 23 contacts the inclined support plate 13 and extends against the inclined support plate 13, the inclination angle of the first driving telescopic rod 23 changes accordingly. The first driving telescopic rod 23 can easily support the inclined support plate 13, further improving the stability of the lifting support device.

[0028] The side groove 19 can be inclined, and when the extension plate 20 extends out of the side groove 19, the extension plate 20 extends out at an angle.

[0029] The drive mechanism facilitates control of the extension plate 20's extension. As the adjusting column 4 extends, the extension plate 20 extends a corresponding length; the higher the adjusting column 4 rises, the longer the extension plate 20 extends beyond the side groove 19. The drive mechanism includes a rack 15 located on the outer wall of the adjusting column 4. A gear 16 is meshed and driven on one side of the rack 15. The gear 16 is rotatably connected to the limiting cylinder 6 via a first rotating shaft 17. A traction rope 18 is wound on the first rotating shaft 17. One end of the traction rope 18 is connected to the outer wall of the first rotating shaft 17, and the other end of the traction rope 18 is connected to the extension plate. One end of the 20 is connected to the bottom of the side groove 19. The bottom of the side groove 19 is connected to the extension plate 20 through the traction spring 21. A through pipe for the traction rope 18 to pass through is provided in the support frame. A second through pipe is provided at the upper end of the opening of the side groove 19, which is connected to the first through pipe and is used for the traction rope 18 to pass through. The other end of the traction rope 18 extends out of the second through pipe and enters the side groove 19 to connect with the extension plate 20. When the adjusting column 4 moves upward, the rack 15 moves to drive the gear 16 to rotate. The first rotating shaft 17 winds up the traction rope 18, causing the extension plate 20 to extend out of the side groove 19.

[0030] The telescopic end of the first drive telescopic rod 23 is connected to a sliding plate 27. The sliding plate 27 is provided with an anti-slip rubber pad on the side facing the inclined support plate 13. The inclined support plate 13 is provided with a mating groove 26 that cooperates with the sliding plate 27. The anti-slip rubber pad extends into the mating groove 26 to facilitate the contact between the sliding plate 27 and the inclined support plate 13.

[0031] A locking element is provided on the abutment plate 27, and a locking rod is connected to the locking element. Multiple locking slots that cooperate with the locking rod are provided at equal intervals in the mating groove 26. The locking element controls the locking rod to be inserted into the locking slot to lock the abutment plate 27 onto the inclined support plate 13.
