Description

Technical Field

[0001] This invention relates to the field of semi-submersible vessel guide positioning pile technology, specifically a semi-submersible vessel guide positioning pile. Background Technology

[0002] Positioning piles are construction positioning devices made primarily of steel pipes or concrete. They are industrial products used for on-site positioning before building construction, mainly applied in yacht marinas, building construction, and bridge construction. Their foundation structure requires at least four positioning points to guide the construction layout, and the stability of the pile body is ensured through bearing capacity calculations.

[0003] Patent publication number CN214084675U describes a semi-submersible vessel guide positioning pile, comprising a vertical main support pipe, with inclined support pipes connected to both ends of the vertical main support pipe at its middle section. The other ends of the inclined support pipes are connected to bottom sealing plates. An I-beam is mounted on the front of the vertical main support pipe, with bolt holes on its side. Anti-collision buffer pads are embedded inside the I-beam, and their sides are fixed to the I-beam using bolts that align with the bolt holes. A horizontal support pipe is connected to the middle of the inclined support pipe at one end, and the other end of the horizontal support pipe is connected to the vertical main support pipe. A forklift-assisted shifting beam is installed between the two horizontal support pipes. The addition of horizontal support pipes between the inclined and vertical main support pipes makes the structure more robust. During installation and use, only the bottom sealing plates of the vertical main support pipe and the two inclined support pipes need to be welded, reducing the amount of welding work.

[0004] However, during semi-submersible vessel transport operations, the main deck needs to be submerged underwater. Therefore, cylindrical positioning stakes need to be installed on the deck in advance to assist operators in accurately positioning the cargo during the loading process. Over time, the bolts of these semi-submersible vessel positioning stakes are prone to rusting and loosening due to prolonged immersion in seawater, which reduces the stability of the positioning stakes and poses a safety risk for subsequent use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a semi-submersible vessel guide positioning pile, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a semi-submersible vessel guide positioning pile, including an installation plate, a positioning column fixedly installed on the upper side of the installation plate, an installation opening on the outer wall of the installation plate, a protective device to prevent water erosion provided on the upper side of the installation plate, and a fixing device to prevent movement after installation provided on the upper side of the installation plate. The protective device includes a screw, a motor, a protective plate, an air box, a push rod, a connecting plate, a push plate, a sealing gasket, and an air pipe. The motor is fixed to the side wall of the mounting plate, the end of the screw is fixed to the output end of the motor, and the end of the screw away from the motor is rotatably mounted on the top inner side of the mounting plate. The protective plate is slidably mounted on the outer wall of the mounting plate and is threadedly connected to the outer wall of the screw. When the motor starts, the motor rotates the screw, thereby driving the protective plate to move towards the installed bolt.

[0007] According to the above technical solution, the air box is fixedly installed on the front side of the mounting plate, the push rod passes through the front side of the air box and is slidably connected at the passage, the connecting plate is fixedly installed on the front side of the push rod, and the connecting plate is fixedly installed on the front side of the protective plate.

[0008] According to the above technical solution, the push plate is fixedly installed on the rear side of the push rod, the sealing gasket is fixedly installed on the inner wall of the installation port, the rear side of the air pipe is fixedly installed on the front side of the sealing gasket, and the front side of the air pipe is fixedly installed on the rear side of the air box. When the protective plate moves, the connecting plate drives the push rod to move as well, so that the push plate pushes the gas in the air box into the air pipe, thereby expanding the sealing gasket in the installation port.

[0009] According to the above technical solution, a fixing device to prevent movement after installation is provided on the upper side of the mounting plate. The fixing device includes a hollow plate, a clamping plate, a tension spring, a pressing block, a fixing plate, a moving column, a U-shaped block, a roller, and a compression spring. The hollow plate is fixedly installed on the upper side of the mounting plate. The clamping plate is slidably connected to the inner wall of the hollow plate. The tension spring is fixedly installed between the two clamping plates. The pressing block is fixedly installed on the inner wall of the protective plate. When the protective plate moves, it will drive the pressing block to press against the clamping plate, so that the two clamping plates move closer to each other and the tension spring is under pressure. When the pressing block no longer presses against the clamping plate, the tension spring is no longer under force and the tension spring will reset the two clamping plates.

[0010] According to the above technical solution, the fixing plate is fixedly installed on the inner wall of the protective plate, the moving column passes through the outer wall of the fixing plate and is slidably connected at the penetration point, the U-shaped block is fixedly installed on the lower side of the moving column, and the roller is rotatably connected to the inner wall of the U-shaped block.

[0011] According to the above technical solution, the upper side of the compression spring is fixedly installed on the lower side of the fixing plate, and the lower side of the compression spring is fixedly installed on the upper side of the U-shaped block. During the process of the protective plate moving towards the installed bolt, the roller under the U-shaped block will squeeze the installed bolt, thereby squeezing the compression spring, which can make the moving column move upward. When the protective plate moves backward, the roller will no longer squeeze the installed bolt, and the compression spring will reset the U-shaped block.

[0012] According to the above technical solution, a stabilizing device to enhance the stability of the device is provided on the upper side of the mounting plate. The stabilizing device includes a support plate, a rotating column, a limiting plate, a limiting hole, a support foot, and a torsion spring. The support plate is fixedly installed on the upper side of the mounting plate, and the rotating column passes through the outer wall of the support plate and is rotatably connected at the through-hole.

[0013] According to the above technical solution, the limiting plate passes through the left side of the hollow plate and is slidably connected at the through point. The right side of the limiting plate is fixedly installed on the left side of the clamping plate. The limiting hole is opened on the outer wall of the rotating column, and the left side of the limiting plate is attached to the limiting hole.

[0014] According to the above technical solution, the support foot is fixedly connected to the outer wall of the rotating column, the rear side of the torsion spring is fixedly installed on the front side of the support foot, and the front side of the torsion spring is fixedly installed on the rear side of the support plate. When the two clamping plates approach each other, the limiting plate disengages from the limiting hole on the rotating column, so that the torsion spring is no longer under pressure, the rotating column rotates counterclockwise, and the support foot rotates counterclockwise downward. When the limiting plate is in the limiting hole of the rotating column, the torsion spring is under force, so that the support foot returns to its original position.

[0015] This invention provides a semi-submersible vessel guide positioning stake. It has the following beneficial effects: 1. This invention, by setting up a protective device, uses a motor to drive the screw to rotate, thereby enabling the protective plate to shield and protect the bolts after installation, preventing them from corroding and loosening due to seawater erosion. This solves the problem of loose bolts causing the positioning pile to shake. Furthermore, a sealing gasket is set at the installation port. By pushing the push plate in the air box with a push rod, gas is quickly flowed from the air pipe into the sealing gasket, causing the gasket to expand and tightly adhere to the inner wall of the installation port and the outer wall of the bolt. This isolates the bolt and the installation port from contact with seawater, preventing oxidation and rust, and thus achieving the effect of preventing seawater from corroding the bolts.

[0016] 2. This invention, through the setting of a fixing device, allows the pressing block to move backward and press against the clamping plate in the hollow plate after the bolt is installed. This brings the two clamping plates closer together and fixes the bolt, preventing it from loosening due to vibration, impact, or other factors, thus ensuring connection safety. Furthermore, during the protective plate's movement towards the bolt, the roller under the U-shaped block presses against the top of the installed bolt, thereby compressing the spring force and driving the moving column upward to press the top of the bolt firmly. This helps prevent the bolt from shifting vertically after installation, which could lead to poor installation stability.

[0017] 3. This invention, by setting up a stabilizing device and limiting the rotating column with a limiting plate, allows the limiting plate to disengage from the limiting hole of the rotating column when the clamping plate moves toward the bolt after installation. This causes the torsion spring to be no longer under force, enabling the support foot to rotate counterclockwise downwards. This allows the support foot to provide oblique support to the positioning pile, improving the stability of the mounting plate and preventing the mounting plate from collapsing due to severe shaking.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 One embodiment of the present invention is: a semi-submersible vessel guide positioning pile, including an installation plate 1, a positioning column 2 fixedly installed on the upper side of the installation plate 1, an installation opening 3 opened on the outer wall of the installation plate 1, a protective device to prevent water erosion provided on the upper side of the installation plate 1, and a fixing device to prevent movement after installation provided on the upper side of the installation plate 1. The protective device includes a screw 41, a motor 42, a protective plate 43, an air box 44, a push rod 45, a connecting plate 46, a push plate 47, a sealing gasket 48, and an air pipe 49. The motor 42 is fixed to the side wall of the mounting plate 1. The end of the screw 41 is fixed to the output end of the motor 42. The end of the screw 41 away from the motor 42 is rotatably mounted on the inner top of the mounting plate 1. The protective plate 43 is slidably mounted on the outer wall of the mounting plate 1 and is threadedly connected to the outer wall of the screw 41. After the bolt is installed, the motor 42 starts, thereby driving the screw 41 to rotate, which in turn moves the protective plate 43 toward the installed bolt. The air box 44 is fixedly mounted. The push rod 45 is installed on the front side of the mounting plate 1 and passes through the front side of the air box 44, with a sliding connection at the passage. The connecting plate 46 is fixedly installed on the front side of the push rod 45 and the protective plate 43. The push plate 47 is fixedly installed on the rear side of the push rod 45. The sealing gasket 48 is fixedly installed on the inner wall of the mounting port 3. The rear side of the air pipe 49 is fixedly installed on the front side of the sealing gasket 48, and the front side of the air pipe 49 is fixedly installed on the rear side of the air box 44. During the movement of the protective plate 43, the connecting plate 46 drives the push rod 45 to move as well, so that the push plate 47 drives the gas in the air box 44 to push into the air pipe 49, which can cause the sealing gasket 48 to expand.

[0022] The motor 42 drives the screw 41 to rotate, thereby the protective plate 43 shields and protects the bolts after installation, preventing the bolts from corroding and loosening due to seawater erosion, thus solving the problem of loose bolts causing the positioning pile to shake. Furthermore, a sealing gasket 48 is provided at the installation port 3. By pushing the push plate 47 in the air box 44 through the push rod 45, gas is quickly flowed from the air pipe 49 into the sealing gasket 48, causing the sealing gasket 48 to expand and tightly fit the inner wall of the installation port 3 and the outer wall of the bolt. This isolates the bolt and the installation port 3 from seawater, preventing oxidation and rust, and thus preventing seawater from corroding the bolt.

[0023] In this embodiment, the device is first placed in a designated position, and the position is determined so that the mounting port 3 on the mounting plate 1 is aligned with the threaded hole on the deck. Then, bolts are installed on the mounting port 3 to fix the positioning post 2 on the mounting plate 1. After installation, the motor 42 is started. The motor 42 drives the screw 41 on the mounting plate 1 to rotate, thereby moving the protection plate 43 toward the installed bolt to protect the bolt. At the same time, the connecting plate 46 moves with the push rod 45 along with the protection plate 43, thereby pushing the push plate 47 toward the air pipe 49 to push the gas into the air pipe 49. The gas then enters the sealing gasket 48 on the mounting port 3, and the sealing gasket 48 expands to block seawater from the bolt installed on the mounting port 3. When the bolt needs to be disassembled, the motor 42 is started, causing the screw 41 to move the protective plate 43 away from the top of the bolt, exposing the bolt. As the protective plate 43 moves, the connecting plate 46 can also move, thereby causing the push rod 45 to drive the push plate 47 to reset. The gas in the sealing gasket 48 can be extracted through the air pipe 49, so that the sealing gasket 48 no longer squeezes the bolt, thus allowing the bolt to be disassembled.

[0024] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, a fixing device to prevent movement after installation is provided on the upper side of the mounting plate 1. The fixing device includes a hollow plate 51, a clamping plate 52, a tension spring 53, a pressing block 54, a fixing plate 55, a moving column 56, a U-shaped block 57, a roller 58, and a compression spring 59. The hollow plate 51 is fixedly installed on the upper side of the mounting plate 1. The clamping plate 52 is slidably connected to the inner wall of the hollow plate 51. The tension spring 53 is fixedly installed between the two clamping plates 52. The pressing block 54 is fixedly installed on the inner wall of the protective plate 43. During the process of the protective plate 43 moving towards the bolt after installation, the pressing block 54 will press against the clamping plate 52, and the tension spring 53 will be under pressure, so that the two clamping plates 52 move closer to each other. When the pressing block 54 no longer presses against the clamping plate 52, the tension spring 53 will release pressure. The two clamping plates 52 are reset. The fixing plate 55 is fixedly installed on the inner wall of the protective plate 43. The moving column 56 passes through the outer wall of the fixing plate 55 and is slidably connected at the penetration point. The U-shaped block 57 is fixedly installed on the lower side of the moving column 56. The roller 58 is rotatably connected to the inner wall of the U-shaped block 57. The upper side of the compression spring 59 is fixedly installed on the lower side of the fixing plate 55, and the lower side of the compression spring 59 is fixedly installed on the upper side of the U-shaped block 57. During the movement of the protective plate 43, the roller 58 under the U-shaped block 57 will squeeze the installed bolt. The compression spring 59 is under pressure, which makes the moving column 56 move upward. When the protective plate 43 moves backward to open the area where the bolt is located, the roller 58 no longer squeezes the installed bolt, the compression spring 59 is no longer under force, and the compression spring 59 will reset the U-shaped block 57.

[0025] After the bolts are installed, the pressing block 54 moves backward and presses against the clamping plate 52 in the hollow plate 51, so that the two clamping plates 52 come close to each other and fix the bolts. This helps to prevent the bolts from loosening on their own due to vibration, impact and other factors, and ensures the safety of the connection. Furthermore, during the process of the protective plate 43 moving towards the bolt for protection, the roller 58 under the U-shaped block 57 presses against the top of the bolt after installation, thereby compressing the force of the spring 59 to drive the moving column 56 upward, pressing the top of the bolt, which helps to prevent the bolt from becoming loose in the upper and lower positions after installation, resulting in poor installation stability.

[0026] A stabilizing device to enhance the stability of the device is provided on the upper side of the mounting plate 1. The stabilizing device includes a support plate 61, a rotating column 62, a limiting plate 63, a limiting hole 64, a support foot 65, and a torsion spring 66. The support plate 61 is fixedly installed on the upper side of the mounting plate 1. The rotating column 62 passes through the outer wall of the support plate 61 and is rotatably connected at the penetration point. The limiting plate 63 passes through the left side of the hollow plate 51 and is slidably connected at the penetration point. The right side of the limiting plate 63 is fixedly installed on the left side of the clamping plate 52. The limiting hole 64 is opened on the outer wall of the rotating column 62. The left side of the limiting plate 63 fits against the limiting hole 64. The foot 65 is fixed to the outer wall of the rotating column 62. The rear side of the torsion spring 66 is fixedly installed on the front side of the support foot 65, and the front side of the torsion spring 66 is fixedly installed on the rear side of the support plate 61. As the two clamping plates 52 approach each other, the clamping plates 52 will drive the limiting plate 63 to move to the right, which can disengage from the limiting hole 64 of the rotating column 62, so that the torsion spring 66 is no longer under force, the rotating column 62 can rotate counterclockwise, and the support foot 65 also rotates counterclockwise downward. When the limiting plate 63 is in the limiting hole 64 of the rotating column 62, the torsion spring 66 will reset the support foot 65.

[0027] By limiting the rotating column 62 with the limiting plate 63, when the clamping plate 52 moves toward the installed bolt, the limiting plate 63 disengages from the limiting hole 64 of the rotating column 62, so that the torsion spring 66 is no longer under force, and the support foot 65 can rotate counterclockwise downward, so that the support foot 65 provides oblique support to the positioning pile, improving the stability of the mounting plate 1 and avoiding the problem of the mounting plate 1 shaking and collapsing.

[0028] In this embodiment, when the protective plate 43 moves towards the installed bolt, the protective plate 43 will drive the pressing block 54 to press against the inclined surface of the clamping plate 52 in the hollow plate 51, causing the two sets of clamping plates 52 in the hollow plate 51 to move closer to each other, thereby compressing the tension spring 53. The two clamping plates 52 move closer to each other to clamp the bolt and prevent loosening. At the same time, the roller 58 under the U-shaped block 57 will press against the installed bolt, thereby causing the moving column 56 on the fixed plate 55 to move upward, and the compression spring 59 to be under force, which will fix the bolt under the roller 58 and prevent it from shifting up and down. When the motor 42 drives the screw 41 to rotate backward, the pressing block 54 driven by the protective plate 43 will no longer press against the clamping plate 52, thereby the tension spring 53 will no longer be under force, the tension spring 53 will reset the two clamping plates 52, the roller 58 under the U-shaped block 57 will no longer press against the installed bolt, the compression spring 59 will no longer be compressed, the moving column 56 will move downward, and the compression spring 59 will reset the U-shaped block 57.

[0029] As the two clamping plates 52 approach each other, the clamping plates 52 will drive the limiting plate 63 to move to the right, so that the limiting plate 63 will fall out of the limiting hole 64 in the rotating column 62, thereby releasing the limiting of the rotating column 62 on the support plate 61. The torsion spring 66 is no longer under the supporting force, causing the rotating column 62 to rotate counterclockwise, so that the support foot 65 also rotates counterclockwise downwards and contacts the deck, thereby enhancing stability.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
