Description

Technical Field

[0001] The invention relates to a floating platform connecting device and an installation method. Background Art

[0002] Floating platforms are often used in inland waters with large water level differences. Steel approach bridges are often used for ship-to-shore connections on floating platforms due to their low cost and adaptability to water levels. One end of the steel approach bridge is fixed to the bank and the other to the floating platform. As the water level fluctuates, the steel approach bridge undergoes angular displacement at the bank and, at the floating platform, both angular and lateral displacement. Therefore, the reserved supports on the bank and the floating platform are critical nodes of the steel approach bridge.

[0003] Traditional floating platforms are surrounded by limit piles to ensure vertical movement of the platform up and down, and to ensure that the horizontal projection position of the floating platform remains relatively unchanged, so as to ensure that the floating platform maintains a relatively constant position on the shore, facilitating the transportation of cargo. However, the traditional method of piling takes a long time, and the stability of the pile body is related to the hardness of the riverbed and the strength of the pile body, which is overall time-consuming and resource-intensive. Summary of the Invention

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and examples.

[0026] Refer to the attached Figure 1 -Attached Figure 6, a floating platform connection device, including a steel approach bridge 200 connected to the corbel 110 of the floating platform 100, and a limit seat 300 for connecting the steel approach bridge 200. The floating platform 100 can be connected to the limit seat 300 on the shore through the steel approach bridge 200 to ensure the relative stability of the position of the floating platform 100 and avoid drifting with the water flow; a second rotation joint 400 is provided between the steel approach bridge 200 and the limit seat 300, where the second rotation joint 400 includes a first mounting seat 410, a second mounting seat 430 and a rotating member 420 rotatably connected therebetween, the first mounting seat 410 and the steel approach bridge 200 are detachably fixed, and the second mounting seat 430 and the limit seat 300 are detachably fixed to ensure the normal deflection of the steel approach bridge 200 during the lifting and lowering process of the floating platform 100.

[0027] When the water level changes, the floating platform 100 changes with the water level. When the length of the steel approach bridge 200 remains unchanged, the floating platform 100 moves along the virtual circumference ( Figure 1 、 Figure 2 In order to ensure that the horizontal projection position of the floating platform 100 remains relatively unchanged while maintaining the strength of the connection structure, the stability of the connection between the steel approach bridge 200 and the floating platform 100 is ensured; a sliding joint 600 is installed on the surface of the corbel 110 of the floating platform 100, and a first rotating joint 500 is installed on the upper end of the sliding joint 600, which is connected to the first end of the steel approach bridge 200 through the first rotating joint 500; during the floating platform 100 floating process, during the vertical ascent of the floating platform 100 (ideal situation), the sliding joint 600 moves outward (toward the floating platform 100) to avoid the concentration of force on the local structure caused by the floating platform 100 floating, avoid damage to the materials at the connection between the floating platform 100 and the steel approach bridge 200, and ensure the long-term stability of the connection between the floating platform 100 and the steel approach bridge 200.

[0028] The sliding joint 600 here includes a sliding positioning seat 610 and a sliding element 620 that rotates with the sliding positioning seat 610. A sliding limit groove 111 is opened on the surface of the corbel 110 to limit the moving direction of the sliding element 620; the first rotating joint 500 includes a rotating positioning seat 510 and a rotating element 520. The rotating positioning seat 510 and the sliding positioning seat 610 are rotatably connected through the rotating element 520, and the top of the rotating positioning seat 510 is connected to the steel approach bridge 200 to ensure the stability of the connection structure.

[0029] Limit piles are driven into the four sides of the conventional floating platform 100 to ensure that the floating platform 100 can move vertically up and down, and to ensure that the horizontal projection position of the floating platform 100 remains relatively unchanged, so as to ensure that the floating platform 100 is in a relatively constant position on the shore, which is convenient for transporting goods. However, the conventional method of piling takes a long time, and the stability of the pile body is related to the hardness of the riverbed and the strength of the pile body, which is time-consuming and resource-intensive as a whole. In order to solve the above problems, a sliding control device 700 for controlling the position of the sliding joint 600 is installed on the surface of the bracket 110 of the floating platform 100, and a floating control device 900 is fixedly provided at the bottom of the floating platform 100. The sliding control device 700 is adjusted by the change of the floating control device 900. The bending state of the device 700 is used to drive the sliding joint 600 to move; specifically, during the floating process of the floating platform 100, the hydraulic oil in the floating control device 900 can be squeezed into the sliding control device 700 to control the sliding control device 700 to contract. During the contraction of the sliding control device 700, the sliding joint 600 and the first rotating joint 500 can be pulled to move in the outward direction (towards the floating platform 100). At this time, relative to pulling the floating platform 100 as a whole toward the steel approach bridge 200 by a predetermined distance, the horizontal deviation of the floating platform 100 during the floating process is offset, thereby ensuring the relative consistency of the overall horizontal projection surface of the floating platform 100 after floating, which is convenient for stable transportation of goods.

[0030] By adopting the above-mentioned structural design, there is no need to pile on the riverbed surface, which greatly reduces the initial construction cost and improves the connection and positioning efficiency of the floating platform 100; at the same time, the floating platform 100 can be pulled and limited from the bottom through the floating control device 900, and the floating platform 100 can be pulled and limited from the inclined top through the steel approach bridge 200, ensuring the stability of the floating position of the floating platform 100 on the river surface; in particular, the rising buoyancy of the floating platform 100 can be converted into a horizontal pulling force of the sliding control device 700, so that the floating platform 100 moves a predetermined distance toward the shore, so as to ensure the relative consistency of the horizontal projection position of the floating platform 100, ensure the accuracy of the docking position of other ships, and facilitate stable transportation of goods.

[0031] Specifically, the floating control device 900 includes an elastic first hydraulic control rod, and the sliding control device 700 includes an elastic second hydraulic control rod 740. After the floating platform 100 floats, the hydraulic oil in the first hydraulic control rod is squeezed into the second hydraulic control rod 740, and then the bending state of the sliding control device 700 is adjusted to drive the sliding joint 600 to move. By controlling the extension and retraction of the second hydraulic control rod 740, the sliding joint 600 can be pulled to different positions to complete displacement control.

[0032] Please refer to the attached Figure 6Specifically, a first control piston 910 is sealed and slides inside the first hydraulic control rod. A first telescopic end 920 is fixedly connected to the side wall of the first control piston 910. A first hydraulic control chamber 940 is formed between the bottom of the first control piston 910 and the interior of the first hydraulic control rod. The bottom of the first telescopic end 920 is fixed. During the raising and lowering of the floating platform 100, the first hydraulic control chamber 940 is controlled to change. A first elastic element 930 is provided between the first control piston 910 and the base end to control the reset of the first telescopic end 920. Hydraulic oil is contained in the first hydraulic control chamber 940, which is located at the bottom. During the overall buoyancy of the floating platform 100, the space in the first hydraulic control chamber 940 decreases, allowing the hydraulic oil inside to be squeezed into the second hydraulic control rod 740 to control the extension of the second hydraulic control rod 740, thereby pulling the sliding joint 600 toward the floating platform 100 from the outside, controlling the overall movement of the floating platform 100 toward the steel approach bridge 200, and completing the drive control.

[0033] Specifically, a second control piston 741 is sealed and sliding inside the second hydraulic control rod 740, and a second hydraulic control chamber 744 located at the bottom is formed between the second control piston 741 and the second hydraulic control rod 740, which also includes a second telescopic end 742 and a second elastic element 743 sleeved on the outside of the second telescopic end 742; the hydraulic oil squeezed into the floating control device 900 can enter the second hydraulic control chamber 744 to control the movement of the second control piston 741, and then control the extension of the second telescopic end 742. In the process of hydraulic oil reflux, the second control piston 741, the second telescopic end 742 and other structures can be controlled to reset through the second elastic element 743, thereby realizing automatic telescopic control.

[0034] By changing the installation position and installation structure of the second hydraulic control rod 740, the hydraulic oil can also be placed in a chamber opposite to the first hydraulic control chamber 940. During the process of extracting the oil in the second hydraulic control rod 740, the second hydraulic control rod 740 is reset under the action of the internal elasticity, thereby realizing the drive control of the position of the sliding joint 600.

[0035] In order to adapt to riverbeds of different water depths, an anchoring rope 921 is fixedly connected to the end of the first telescopic end 920, and an anchor claw is fixed to the bottom of the anchoring rope 921. By placing the anchor claw at the bottom of the riverbed, the stability of the overall structure of the floating platform 100 can be ensured. During the anchoring process, the anchoring rope 921 is kept in a taut state to ensure stable oil control.

[0036] Please refer to the attached Figure 4Specifically, the sliding control device 700 includes a first control rod 720 and a second control rod 730. The first ends of the first control rod 720 and the second control rod 730 are rotatably connected, the second end of the first control rod 720 is rotatably connected to the sliding joint 600, the second end of the second control rod 730 is rotatably connected to the surface of the corbel 110, and the second hydraulic control rod 740 is installed between the corbel 110 and the second control rod 730.

[0037] During the extension and retraction process of the second hydraulic control rod 740, the deflection angle of the second control rod 730 can be changed, thereby pulling the first control rod 720 to drive the sliding joint 600 to move as a whole, thereby realizing the drive control of horizontal sliding. Through the above structural design, compared with the direct drive of the sliding joint 600 by the single-design second hydraulic control rod 740, the overall drive path stroke is longer, the structure in the horizontal direction after the overall contraction is more compact, and the horizontal position control is more stable.

[0038] An elastic connection joint 710 is provided between the second end of the first control rod 720 and the sliding joint 600. The elastic connection joint 710 here can be an elastic telescopic rod with a guide structure. By providing the elastic connection joint 710, a buffer can be provided between the position control device 800 and the first control rod 720 to avoid rigid collision of the overall structure during movement, thereby improving the service life of the overall structure and reducing the probability of local impact damage; the elastic telescopic distance of the elastic connection joint 710 here is determined according to the requirements of the floating platform 100 for transporting goods.

[0039] A position control device 800 is installed at the upper end of the corbel 110, which drives the base end of the second hydraulic control rod 740 to move to different positions through the position control device 800. By controlling the second hydraulic control rod 740 to be in different positions, the bending state of the first control rod 720 and the second control rod 730 can be changed. Without adjusting the telescopic size of the second hydraulic control rod 740, the moving path of the sliding joint 600 can be adjusted, meeting the operational requirements under different river conditions and different cargo transportation conditions.

[0040] In order to avoid collision between the moving sliding joint 600 and related structures such as the positioning device 800 and to increase the range of movement of the sliding joint 600, the second hydraulic control rod 740 and the positioning device 800 and other structures here can be selected as two symmetrical groups, which are staggered with the moving path of the sliding joint 600. At the same time, by setting up two groups of the above structures, the stability of the extension and retraction of the overall structure can be ensured from both sides.

[0041] As a preferred position control method, the position control device 800 here includes a position control slider 810 that is slidably connected to the surface of the corbel 110. The surface of the corbel 110 is electrically controlled to rotate with a position control screw 820. The position control screw 820 passes through the position control slider 810 and is adapted to it. The position control screw 820 is continuously rotated by the motor. During the rotation process, the position control screw 820 can control the horizontal movement of the position control slider 810, thereby controlling the position control slider 810 to drive the second hydraulic control rod 740 to different positions. The base end of the second hydraulic control rod 740 here can be selectively rotatably installed inside the groove of the position control slider 810 to ensure that the second hydraulic control rod 740 can be smoothly adjusted and controlled. At the same time, after the hydraulic system of the floating control device 900 and the second hydraulic control rod 740 fails, the position of the sliding joint 600 can be auxiliary controlled by the position control device 800 to achieve adjustment of the position of the sliding joint 600, thereby ensuring the accurate position of the floating platform 100 structure on the horizontal projection plane.

[0042] A method for installing a floating platform connection device comprises the following steps:

[0043] S1. A floating control device 900 is fixed to the bottom of the floating platform 100, and the telescopic end of the floating control device 900 is fixed; specifically, the bottom is fixed to the fluke through an anchor rope 921, so that the anchor rope 921 is in a taut state.

[0044] S2. Control the sliding joint 600 to be in a predetermined position, connect the sliding control device 700 to the sliding joint 600, and then control the floating control device 900 and the sliding control device 700 to be in a conductive state; adjust the bending state of the sliding control device 700 through the changes of the floating control device 900 to drive the sliding joint 600 to move, so as to ensure that the horizontal projection position of the floating platform 100 remains relatively unchanged.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
