When winding the straight pile, the winding device drives the anti-corrosion tape to wind around the straight pile and rotate at the same time, and the lifting device drives the winding device to move upwards relative to the working platform, so that the anti-corrosion tape can be automatically wound on the straight pile from bottom to top, which greatly saves the labor and improves the construction efficiency.

[0009] In addition, the anti-corrosion construction platform provided by the embodiments of the present application also has the following additional technical features:

[0010] In some embodiments of the present application, the winding device comprises a base body, a moving ring and a driving device.

[0011] The base body is movably arranged on the working platform, and the lifting device is used to drive the base body to move up and down relative to the working platform.

[0012] The moving ring is rotatably arranged on the base body.

[0014] In the above technical solution, the dynamic ring is rotatably mounted on the base. After the dynamic ring is sleeved on the outside of the vertical pile, the dynamic ring is driven to rotate by the driving device, which drives the anti-corrosion tape to rotate around the vertical pile, thereby wrapping the anti-corrosion tape around the vertical pile. This winding method, which drives the anti-corrosion tape roll by rotating the dynamic ring, has a simple structure and is easy to implement.

[0015] In some embodiments of the present application, a guide ring is provided on the base;

Since the two half rings are detachable, and the two half rings and the base are also detachable, the half rings can be easily replaced when the diameter of the straight pile changes.

[0020] In some embodiments of the present application, the cross section of the semi-ring is L-shaped.

[0021] In the above technical solution, the cross section of the half ring is an L-shaped structure, which can achieve axial and radial limiting of the half ring, thereby improving the stability of the dynamic ring during rotation.

[0022] In some embodiments of the present application, the driving device includes a power unit and a first gear;

[0023] The first gear is rotatably disposed on the base, and the power unit is used to drive the first gear to rotate relative to the base;

[0024] The movable ring has a toothed portion meshing with the first gear.

[0025] In the above technical solution, the first gear meshes with the toothed portion of the dynamic ring, and the power unit drives the first gear to rotate, thereby causing the dynamic ring to rotate relative to the base. The overall structure of this driving device is relatively simple.

[0030] In some embodiments of the present application, the working platform comprises a plurality of platform units arranged circumferentially on the outer side of the straight pile.

[0031] Each two adjacent platform units are connected by a connecting piece.

[0032] In the above technical solution, the working platform comprises a plurality of platform units arranged circumferentially on the outer side of the straight pile, i.e. the plurality of platform units surround the straight pile, so that the straight pile limits the movement of the working platform on the water surface, thereby ensuring that the working platform has good stability on the water surface.

[0033] In some embodiments of the present application, the connecting piece is a telescopic structure.

[0034] In the above technical solution, the connecting piece is a telescopic structure. By extending or shortening the connecting piece, the gap between the two adjacent platform units can be changed, so as to adapt to straight piles of different diameters.

[0035] In some embodiments of the present application, a damping pad is arranged on the side of the platform unit facing the straight pile.

[0050] Embodiments

[0051] The embodiments of the present application provide an anti-corrosion construction platform 100, which is simple and compact in structure, easy to install and disassemble, can greatly save labor and improve construction efficiency. The specific structure of the anti-corrosion construction platform 100 will be described in detail below in combination with the drawings.

[0052] As shown in Figure 1 The anti-corrosion construction platform 100 includes a working platform 10, a wrapping device 20, and a lifting device 30. The working platform 10 is provided with a floating body 40. The wrapping device 20 is used to drive the anti-corrosion tape to rotate around the straight pile. The lifting device 30 is used to drive the wrapping device 20 to move up and down relative to the working platform 10.

[0053] The working platform 10 is provided with a floating body 40, so that the working platform 10 floats on the water surface, and the construction personnel can perform the wrapping work on the straight pile on the working platform 10. When wrapping the straight pile, the wrapping device 20 is used to drive the anti-corrosion tape to rotate around the straight pile, and at the same time, the lifting device 30 is used to drive the wrapping device 20 to move upwards relative to the working platform 10, so that the anti-corrosion tape can be automatically wrapped on the straight pile from bottom to top, greatly saving labor and improving construction efficiency.

[0054] Among them, as shown in Figure 2As shown, the working platform 10 includes a plurality of platform units 11 arranged circumferentially outside the straight piles, and every two adjacent platform units 11 are connected by a connecting member 12 .

[0055] Each adjacent platform unit 11 in the work platform 10 is connected by a connector 12, so that all platform units 11 form a whole. The multiple platform units 11 in the work platform 10 can surround the vertical piles, so that the vertical piles act to limit the movement of the entire work platform 10 on the water surface, ensuring that the work platform 10 has good stability on the water surface.

[0056] Optionally, the connector 12 is a telescopic structure. By extending or shortening the connector 12, the gap between two adjacent platform units 11 can be adjusted to accommodate vertical piles of varying diameters. Of course, the number of connectors 12 between each pair of adjacent platform units 11 can be one, two, or three. In other embodiments, the connector 12 can also have other structures, such as a single, non-telescopic rod.

[0057] The work platform 10 may include two, three, or four platform units 11. In this embodiment, there are four platform units 11. A gap exists between each pair of adjacent platform units 11. One end of a connector 12 is connected to one platform unit 11 via a rotating shaft, and the other end of the connector 12 is connected to another adjacent platform unit 11 via a rotating shaft.

[0058] When the gap between two adjacent platform units 11 increases due to the elongation of the connecting member 12, a safety iron net 13 can be placed in the gap to allow construction workers to walk.

[0059] Furthermore, a shock-absorbing pad 14 is provided on the side of the platform unit 11 facing the vertical pile. The shock-absorbing pad 14 can play a buffering role when the platform unit 11 moves slightly, thereby preventing the platform unit 11 from rigidly colliding with the vertical pile.

[0060] In this embodiment, the platform unit 11 is roughly rectangular in structure, and two right-angled sides of the platform unit 11 are connected by an inwardly concave arc side. The side where the arc side is located is the side of the platform unit 11 facing the straight pile, that is, the shock-absorbing pad 14 is fixed at the arc side of the platform unit 11.

[0061] For example, the shock-absorbing pads 14 are arc-shaped structures made of rubber. During the installation of the work platform 10 , the distance between the platform unit 11 and the vertical piles can be adjusted by increasing or decreasing the number of shock-absorbing pads 14 to stabilize the work platform 10 .

[0062] In this embodiment, the floating body 40 is a spherical structure, and a floating body 40 is correspondingly provided at the bottom of each platform unit 11 .

[0063] In addition, if Figure 1 As shown, in order to ensure the safety of construction workers on the working platform 10, a guardrail 15 is provided on the platform unit 11. Every two adjacent guardrails 15 are connected by a protective chain 16.

[0064] Furthermore, the work platform 10 is provided with a guide rail 17 for the up and down movement of the belt wrapping device 20. The guide rail 17 is detachably connected to the work platform 10. The guide rail 17 on the work platform 10 serves as a guide, ensuring that the work platform 10 has a defined motion trajectory. The detachable connection between the guide rail 17 and the work platform 10 facilitates installation and transportation.

[0065] Specifically, a guide rail base 18 is fixed to one platform unit 11 of the work platform 10, and a fixed angle iron 19 is provided between the guide rail base 18 and the platform unit 11 for reinforcement. The guide rail 17 is detachably connected to the guide rail base 18. Of course, the guide rail 17 and the guide rail base 18 can be detachably connected by plugging, bolting, etc.

[0066] In this embodiment, the guide rail 17 is composed of 17 fixed-length guide rails spliced ​​together to accommodate vertical piles of different heights. For example, the length of the guide rail 17 is 50 cm.

[0067] During installation, the three platform units 11 without the guide rail base 18 can be assembled first, and then the platform unit 11 with the guide rail base 18 can be connected last. After the four platform units 11 are assembled, the length of the connecting parts 12 and the number of shock-absorbing pads 14 are adjusted to ensure the stability and safety of the entire construction platform, and then the wrapping device 20 can be installed.

[0068] Furthermore, if Figure 3 As shown, the wrapping device 20 includes a base 21, a movable ring 22, and a drive device 23. The base 21 is movably mounted on the guide rail 17 of the work platform 10. The lifting device 30 is used to drive the base 21 to move up and down relative to the guide rail 17. The movable ring 22 is rotatably mounted on the base 21. The drive device 23 is used to drive the movable ring 22 to rotate relative to the base 21, thereby driving the anti-corrosion tape to rotate around the pile.

[0069] In the above structure, the movable ring 22 is rotatably mounted on the base 21. After the movable ring 22 is sleeved onto the outside of the vertical pile, the driving device 23 drives the movable ring 22 to rotate, thereby driving the anti-corrosion tape to rotate around the vertical pile, thereby wrapping the anti-corrosion tape around the vertical pile. This winding method, in which the rotation of the movable ring 22 drives the anti-corrosion tape roll, is simple in structure and easy to implement.

[0070] The movable ring 22 is provided with a mounting frame 222, and the anti-corrosion tape roll can be mounted on the mounting frame 222. When the movable ring 22 drives the anti-corrosion tape roll to rotate around the vertical pile, the anti-corrosion tape roll itself will rotate relative to the mounting frame 222, so that the anti-corrosion tape in the anti-corrosion tape roll is gradually withdrawn and wound onto the vertical pile.

[0071] Optionally, a guide ring 24 is provided on the base 21, and the movable ring 22 is rotatably sleeved on the outer side of the guide ring 24. The provision of the guide ring 24 can ensure the stability of the movable ring 22 during the rotation process.

[0072] In this embodiment, the guide ring 24 includes two half rings 241 , one end of one half ring 241 and one end of the other half ring 241 are both detachably connected to the base 21 , and the other end of one half ring 241 is detachably connected to the other end of the other half ring 241 .

[0073] The guide ring 24 comprises two half rings 241, which can be conveniently arranged outside the straight pile. Since the two half rings 241 are detachable from each other and from the base 21, the half rings 241 can be easily replaced when the diameter of the straight pile changes.

[0074] Exemplarily, the two half rings 241 are detachably connected to the base 21 via screws, and the two half rings 241 are detachably connected to each other via screws.

[0075] Optionally, the cross-section of the half-rings 241 is L-shaped. After the dynamic ring 22 is sleeved onto the two half-rings 241, it rests on the bottom structure of the half-rings 241. This structure provides axial and radial restraint for the half-rings 241, improving the stability of the dynamic ring 22 during rotation. In other embodiments, other structures can be used to achieve axial restraint for the dynamic ring 22. For example, a protrusion can be provided on the outer circumferential wall of the half-rings 241, and an annular groove can be provided on the inner circumferential wall of the dynamic ring 22. The protrusion can be engaged in the annular groove to provide axial restraint.

[0076] It should be noted that the movable ring 22 can also be composed of two half movable rings 22. When the diameter of the straight pile changes and the movable ring 22 needs to be replaced, the two half movable rings 22 can be separated from each other to remove the movable ring 22.

[0077] In this embodiment, the drive device 23 includes a power unit 231 and a first gear 232. The first gear 232 is rotatably mounted on the base 21. The power unit 231 is used to drive the first gear 232 to rotate relative to the base 21. The movable ring 22 has a toothed portion 221 that meshes with the first gear 232. The power unit 231 drives the first gear 232 to rotate, thereby rotating the movable ring 22 relative to the base 21. The overall structure of this drive device 23 is relatively simple.

[0078] Since the movable ring 22 has the toothed portion 221 meshing with the first gear 232 , the movable ring 22 can be regarded as a gear.

[0079] The power unit 231 includes a first motor 2311 and a first worm 2312. The motor is fixed to the base 21. The motor's output shaft is connected to the first worm 2312, which meshes with a first gear 232 (which can be considered a first worm wheel). When the first motor 2311 rotates the first worm 2312, the first gear 232 also rotates the dynamic ring 22.

[0080] Furthermore, the base 21 includes a first movable body 211 and a second movable body 212. The first movable body 211 is movably disposed on the work platform 10, and the lifting device 30 is used to drive the first movable body 211 to move up and down relative to the work platform 10. The movable ring 22 is rotatably disposed on the second movable body 212, and the second movable body 212 is movably disposed on the first movable body 211 along the radial direction of the movable ring 22.

[0081] Because the second movable body 212 is movably mounted on the first movable body 211, and the movable ring 22 is rotatably mounted on the second movable body 212, the position of the movable ring 22 can be changed by moving the second movable body 212 relative to the first movable body 211. When the diameter of the straight pile changes, the position of the movable ring 22 can be changed by changing the position of the second movable body 212, ensuring that the movable ring 22 is substantially concentric with the straight pile.

[0082] In this embodiment, the first movable body 211 and the second movable body 212 are both plate-like structures. The first movable body is provided with a through hole 2111 for the guide rail 17 to pass through. The guide ring 24, the first motor 2311 and the first gear 232 are all installed on the second movable body 212. That is, when the second movable body 212 moves relative to the first movable body 211, the guide ring 24, the moving ring 22, the first motor 2311 and the first gear 232 will all follow the second movable body 212 to move.

[0083] Furthermore, the first movable body 211 and the second movable body 212 are connected by a first telescopic rod 213. One end of the first telescopic rod 213 is fixedly connected to the first movable body 211, and the other end of the first telescopic rod 213 is fixedly connected to the second movable body 212. The second movable body 212 can be moved relative to the first movable body 211 by extending or contracting the first telescopic rod 213. The first telescopic rod 213 extends and contracts in the horizontal direction.

[0084] The number of the first telescopic rods 213 between the first movable body 211 and the second movable body 212 can be one, two, or three.

[0085] To improve the stability of the second movable body 212 during movement, in some embodiments of the present application, the first movable body 211 and the second movable body 212 are further connected by a second telescopic rod 214. A downwardly extending connecting rod 215 is fixed to the bottom of the first movable body 211. One end of the second telescopic rod 214 is hinged to the second movable body 212, and the other end of the second telescopic rod 214 is hinged to the bottom end of the connecting rod 215. The extension direction of the second telescopic rod 214 is arranged at an angle to the horizontal direction.

[0086] Of course, the number of the second telescopic rods 214 between the first movable body 211 and the second movable body 212 may also be one, two, or three.

[0087] The function of the lifting device 30 is to drive the winding device 20 to move up and down. The lifting device 30 can have various structures.

[0088] In this embodiment, combined with Figure 1 and Figure 4 The lifting device 30 includes a drive unit 31, a second gear 32, and a rack 33. The second gear 32 is rotatably mounted on the first movable body 211. The rack 33 is fixed to the guide rail 17. The second gear 32 meshes with the rack 33. The drive unit 31 is configured to drive the second gear 32 to rotate relative to the first movable body 211. When the drive unit 31 drives the second gear 32 to rotate, the first movable body 211 moves along the guide rail 17, thereby achieving the up and down movement of the entire belt wrapping device 20.

[0089] Exemplarily, the drive unit 31 includes a second motor 311, a second worm gear 312, and a second worm 313. The second motor 311 is fixed to the first movable body 211, and the second worm 313 is connected to the output shaft of the second motor 311. The second worm gear 312 is connected to the second gear 32 via a connecting shaft 314, and the second worm 313 meshes with the second worm gear 312. When the second motor 311 rotates and drives the second worm gear 313 to rotate, the second worm gear 312 also drives the second gear 32 to rotate, thereby achieving the up and down movement of the belt winding device 20.

[0090] In other embodiments, the lifting mechanism may also be other structures. For example, the lifting mechanism includes a motor, a roller and a rope. The roller is rotatably arranged on the top of the guide rail 17. The output shaft of the motor is connected to the roller. The rope is wound on the roller. The free end of the rope is connected to the first movable body 211. The motor drives the roller to rotate to retract and release the rope, thereby realizing the up and down movement of the winding device 20.

[0091] The anti-corrosion construction platform 100 provided in the embodiment of the present application realizes the automatic winding of anti-corrosion tape while ensuring the safety of anti-corrosion construction operations on water and at sea, greatly saving labor costs and improving construction efficiency. It can also be flexibly assembled according to different pile diameters for easy disassembly.

[0092] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
