Description

Technical Field

[0001] This utility model relates to wind power operation and maintenance equipment, and in particular to a lifting wave compensation trestle. Background Technology

[0002] When replenishment vessels operate at sea, they are subject to significant swaying due to wind, waves, and tides. When replenishment vessels provide services to offshore wind power plants or fixed platforms, they are constantly in a state of heave and swaying, posing a great risk to personnel working at sea and during transfers. Safe and stable docking of replenishment vessels with platforms is a very important safeguard to ensure the safety of personnel working at sea and during transfers.

[0003] In existing technologies, active wave compensation can be achieved by using trestle docks with wave compensation features. However, due to the significant height difference between the supply vessel and the offshore wind turbine or fixed platform, the wave compensation trestle can only be docked by increasing the pitch angle of the trestle. There are still significant safety hazards for personnel walking on the trestle with a large slope, especially in rainy or snowy weather. Furthermore, the wave compensation process requires frequent angle adjustments, making the operation complicated and the docking efficiency low.

[0004] It is evident that existing technologies suffer from low docking efficiency and significant safety risks when connecting trestle bridges with floating bodies or fixed platforms at sea. Utility Model Content

[0005] This invention provides a lifting wave-compensating pier, which solves the problems of low docking efficiency and high safety risks of existing piers with floating bodies and fixed platforms at sea.

[0006] This utility model provides a lifting wave-compensated trestle, including a lifting component, a wave compensation component, and a trestle component; the trestle component is connected to the lifting component through the wave compensation component, so as to lift and lower under the drive of the lifting component; the wave compensation component is used to drive the trestle component to swing around the wave compensation component, so that at least a part of the trestle component is parallel to the horizontal plane.

[0007] The lifting assembly includes a lifting drive unit, a transmission gear, a fixed rack, a transmission rack, and a lifting platform. Both the fixed rack and the transmission rack extend along the lifting direction of the lifting assembly. The fixed rack is fixedly installed on the deck of the ship and meshes with the first side of the transmission gear. The transmission rack meshes with the second side of the transmission gear opposite to the first side. The lifting drive unit connects to and drives the transmission gear to move along the fixed rack, and drives the transmission rack to move between a first position and a second position.

[0008] The bottom of the lifting platform is connected to the end of the transmission rack away from the lifting drive unit, and the wave compensation component is installed on the top surface of the lifting platform.

[0009] This invention utilizes a lifting mechanism to adjust the height of the pier according to real-time sea conditions, ensuring the pier remains relatively level with the operating platform of the floating body or fixed platform. This avoids personnel having to walk on piers with steep inclines, reducing safety hazards during offshore operations. Furthermore, the lifting mechanism employs a gear and rack system, ensuring smooth and rapid lifting and improving the efficiency of docking the pier with the floating body or fixed platform.

[0010] Optionally, the length of the transmission rack is greater than the length of the fixed rack.

[0011] This embodiment of the utility model uses the above-described structure to form a stroke amplification structure, which increases the lifting stroke of the lifting component, making the lifting function of the lifting wave compensation trestle applicable to a wider height range.

[0012] Optionally, the lifting assembly may also include a mounting wall; the mounting wall is vertically mounted on the deck of the vessel, and a fixing rack is fixed to the mounting wall.

[0013] This embodiment of the utility model uses a mounting wall to fix the rack, which has the advantages of simple installation and convenient maintenance.

[0014] Optionally, the wave compensation assembly includes a compensation platform and multiple drive cylinders.

[0015] The compensation platform and the lifting platform are arranged face to face, and multiple drive cylinders are supported between the compensation platform and the lifting platform to drive the compensation platform to generate an angle with the horizontal plane; wherein, at least some of the multiple drive cylinders are arranged crosswise.

[0016] The trestle assembly is installed on the surface of the compensation platform away from the lifting assembly to follow the swing of the compensation platform.

[0017] This embodiment of the invention utilizes multiple drive cylinders supported between a compensation platform and a lifting platform to adjust the tilt angle of the compensation platform relative to the horizontal plane, thereby compensating for the impact of ocean waves and ensuring that the compensation platform remains relatively level. The staggered arrangement of at least some of the drive cylinders enhances the stability of the compensation platform during tilt adjustment, preventing violent shaking.

[0018] Optionally, the top surface of the lifting platform is provided with a first base, a second base and a third base, and the bottom surface of the compensation platform is provided with a first mounting part, a second mounting part and a third mounting part.

[0025] Optionally, the trestle assembly also includes a base, which is rotatably connected to the wave compensation assembly. A rotation drive unit is connected to the base to drive the base to rotate around a rotation axis, and the bottom of the cylinder is mounted on the base.

[0026] Optionally, the trestle assembly also includes a telescopic rod. The trestle body includes a first trestle segment and a second trestle segment.

[0027] This utility model embodiment achieves the pitching of the second trestle section by extending and retracting the telescopic rods of the diagonal bracing on the cylinder and the second trestle section, which improves the flexibility of trestle operations at sea and enriches the application scenarios of the lifting wave compensation trestle.

This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0040] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0042] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0043] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0045] Please see Figure 1 and Figure 2 This utility model provides a lifting wave-compensated trestle 1, including a lifting assembly, a wave compensation assembly 12, and a trestle assembly 13. The trestle assembly 13 is connected to the lifting assembly via the wave compensation assembly 12, so as to lift and lower under the drive of the lifting assembly. The wave compensation assembly 12 is used to drive the trestle assembly 13 to swing around the wave compensation assembly 12, so that at least a portion of the trestle assembly 13 is parallel to the horizontal plane.

[0046] like Figure 2As shown, the lifting assembly includes a lifting drive unit 111, a transmission gear 112, a fixed rack 113, a transmission rack 114, and a lifting platform 115. Both the fixed rack 113 and the transmission rack 114 extend along the lifting direction of the lifting assembly (or can be understood as a direction perpendicular to the sea level). The fixed rack 113 is fixedly installed on the deck of the ship and meshes with the first side of the transmission gear 112. The transmission rack 114 meshes with the second side of the transmission gear 112 opposite to the first side. The lifting drive unit 111 connects to and drives the transmission gear 112 to move along the fixed rack 113, and drives the transmission rack 114 to move between a first position and a second position.

[0047] The bottom of the lifting platform 115 is connected to the end of the transmission rack 114 away from the lifting drive unit 111, and the wave compensation component 12 is installed on the top surface of the lifting platform 115. The first position corresponds to the lowest position of the lifting platform 115, and the second position corresponds to the highest position of the lifting platform 115.

[0048] This invention, through the installation of a lifting assembly (including a lifting drive unit 111, a transmission gear 112, a fixed rack 113, a transmission rack 114, and a lifting platform 115), enables the pier to adjust its height according to real-time sea conditions. This keeps the pier relatively level with the operating platform of the floating body or fixed platform, preventing personnel from walking on piers with steep inclines and reducing safety hazards during offshore operations. Furthermore, the lifting assembly of this invention uses a gear and rack mechanism, ensuring smooth and rapid lifting and improving the efficiency of docking the offshore pier with the floating body or fixed platform.

[0049] The lifting drive unit 111 can be a motor, hydraulic cylinder, pneumatic cylinder, etc. As long as it is an actuator that can drive the gear to rotate, it does not deviate from the scope of this utility model embodiment.

[0050] In one implementation, such as Figure 1 and Figure 2 As shown, the lifting assembly also includes a mounting wall 116. The mounting wall 116 is vertically installed on the deck of the ship, and the fixed rack 113 is fixed to the mounting wall 116. The form of the mounting wall 116 is not limited; it can be a plate structure or a box structure, enclosing the lifting drive unit 111, the transmission gear 112, the fixed rack 113, and the transmission rack 114 within the space formed by the box structure. This utility model does not limit this. The embodiment of this utility model uses a mounting wall to install the fixed rack, which has the advantages of simple installation and convenient maintenance.

[0051] Those skilled in the art will understand that the number of lifting drive unit 111, transmission gear 112, fixed rack 113, and transmission rack 114 is not limited; there may be one or more. In one embodiment, such as... Figure 1As shown, the number of lifting drive unit 111, transmission gear 112, fixed rack 113, and transmission rack 114 are all three. Furthermore, the installation direction of the transmission gear 112 is not limited; the installation directions of the multiple transmission gears 112 can be the same or different. For example, in one embodiment, such as... Figure 1 As shown, the axial direction of some transmission gears 112 is parallel to the extension direction of the trestle body 130, and the axial direction of some transmission gears 112 is perpendicular to the extension direction of the trestle body 130.

[0052] In one implementation, such as Figure 1 and Figure 2 As shown, the length of the transmission rack 114 is greater than the length of the fixed rack 113. This embodiment of the invention employs the above structure to form a stroke amplification structure, increasing the lifting stroke of the lifting assembly, thus making the lifting function of the lifting wave-compensating trestle 1 applicable to a wider height range.

[0053] Furthermore, in one implementation, such as Figure 2 As shown, the wave compensation assembly 12 includes a compensation platform 121 and multiple drive cylinders (e.g., first drive cylinder 122a, second drive cylinder 122b, third drive cylinder 122c, fourth drive cylinder 122d, fifth drive cylinder 122e, and sixth drive cylinder 122f).

[0054] The compensation platform 121 and the lifting platform 115 are arranged facing each other. Multiple drive cylinders are supported between the compensation platform 121 and the lifting platform 115 to drive the compensation platform 121 to tilt at an angle with the horizontal plane. At least some of the drive cylinders are arranged crosswise. The gantry assembly 13 is installed on the surface of the compensation platform 121 away from the lifting assembly to swing with the compensation platform 121.

[0055] In one embodiment, the wave compensation assembly 12 further includes a platform base 120, which is mounted on the top surface of the lifting platform 115 and is positioned face-to-face with the compensation platform 121. Multiple drive cylinders are supported on the lifting platform 115 via the platform base 120.

[0056] This embodiment of the invention utilizes multiple drive cylinders supported between the compensation platform 121 and the lifting platform 115 to adjust the tilt angle of the compensation platform 121 relative to the horizontal plane, thereby compensating for the impact of ocean waves and ensuring that the compensation platform 121 remains in a relatively horizontal state. The staggered arrangement of at least some of the drive cylinders enhances the stability of the compensation platform 121 during tilt adjustment, preventing violent shaking of the compensation platform 121.

[0057] For details, please see Figure 1In one embodiment, the top surface of the lifting platform 115 is provided with a first base 123, a second base 124 and a third base 125, and the bottom surface of the compensation platform 121 is provided with a first mounting part 126, a second mounting part 127 and a third mounting part 128.

[0058] The first base 123, the second base 124 and the third base 125 are arranged at intervals, and the first mounting part 126, the second mounting part 127 and the third mounting part 128 are arranged at intervals.

[0059] Please combine Figure 1 and Figure 2 Understandably, the multiple drive cylinders include a first drive cylinder 122a, a second drive cylinder 122b, a third drive cylinder 122c, a fourth drive cylinder 122d, a fifth drive cylinder 122e, and a sixth drive cylinder 122f.

[0060] The first drive cylinder 122a is supported and connected at both ends to the first mounting part 126 and the first base 123, and the sixth drive cylinder 122f is supported and connected at both ends to the third mounting part 128 and the third base 125.

[0061] The first end of the second drive cylinder 122b is connected to the first mounting part 126, and the second end of the second drive cylinder 122b is connected to the second base 124. The first end of the third drive cylinder 122c is connected to the second mounting part 127, and the second end of the third drive cylinder 122c is connected to the first base 123. The first end of the fourth drive cylinder 122d is connected to the second mounting part 127, and the second end of the fourth drive cylinder 122d is connected to the third base 125. The first end of the fifth drive cylinder 122e is connected to the third mounting part 128, and the second end of the fifth drive cylinder 122e is connected to the second base 124.

[0062] Those skilled in the art will understand that the driving cylinder can be a hydraulic cylinder or an electric cylinder, etc., which has a reciprocating force.

[0063] Furthermore, in one implementation, such as Figure 2 As shown, the trestle assembly 13 includes a cylindrical body 134, a trestle main body 130, and a rotation drive unit 135. The bottom end of the cylindrical body 134 is rotatably connected to the wave compensation assembly 12, for example, to the compensation platform 121 of the wave compensation assembly 12. The trestle main body 130 is connected to the top end of the cylindrical body 134 and forms a T-shaped structure. The rotation drive unit 135 is used to drive the cylindrical body 134 and the trestle main body 130 to rotate about the rotation axis of the cylindrical body 134. The rotation axis of the cylindrical body 134 can be, for example, the axis of rotation of the cylindrical body 134.

[0064] Those skilled in the art will understand that the rotary drive unit 135 may be, for example, a hydraulic motor, a rotary motor, etc.

[0065] Furthermore, in one embodiment, the trestle assembly 13 further includes a base 136, which is rotatably connected to the wave compensation assembly 12, for example, rotatably connected to the compensation platform 121. A rotation drive unit 135 is connected to the base 136 to drive the base 136 to rotate around the aforementioned rotation axis. The bottom of the cylinder 134 is mounted on the base 136.

[0066] In one implementation, such as Figure 2 As shown, the trestle assembly 13 also includes a telescopic rod 137. The trestle body 130 includes a first trestle section 131 and a second trestle section 132. The first end of the first trestle section 131 is connected to the top of the cylinder 134. The first end of the second trestle section 132 is rotatably connected to the first end of the first trestle section 131. The first end of the telescopic rod 137 is connected to the side wall of the cylinder 134, and the second end of the telescopic rod 137 is connected to the non-end portion of the second trestle section 132 (which can be understood as the portion of the second trestle section 132 other than the end portion), so that the second trestle section 132 moves around the first end of the first trestle section 131 in a direction closer to or further away from the cylinder 134 under the drive of the telescopic rod 137. In one embodiment, the first end of the second trestle section 132 is rotatably connected to the first end of the first trestle section 131 via a pivot 1301. The first trestle section 131 can serve as a waiting platform for operators to stand and wait for the lifting wave-compensating trestle of this embodiment to be properly adjusted.

[0067] This utility model embodiment achieves the pitching of the second trestle section 132 by extending and retracting the telescopic rod 137 that is diagonally supported on the cylinder 134 and the second trestle section 132, which improves the flexibility of the trestle in marine operations and enriches the application scenarios of the lifting wave compensation trestle 1.

[0068] In one implementation, such as Figure 2 As shown, the trestle assembly 13 also includes a telescopic gear 138 and a telescopic rack 139. The telescopic gear 138 is located on the second trestle section 132. The trestle body 130 also includes a telescopic trestle section 133, and the telescopic rack 139 is located on the telescopic trestle section 133. The telescopic trestle section 133 is connected to the second trestle section 132 via the telescopic rack 139 and the telescopic gear 138, and can move towards or away from the second trestle section 132 under the drive of the telescopic gear 138. The telescopic gear 138 can be driven, for example, by an electric motor, a hydraulic motor, or a cylinder. In other alternative embodiments, it can also be manually driven by a rocker arm.

[0069] This utility model embodiment uses telescopic gear 138 and telescopic rack 139 to allow the telescopic trestle section 133 to extend or retract relative to the second trestle section 132, making the length of the trestle flexible and adaptable, further improving the flexibility of trestle operations at sea and enriching the application scenarios of the lifting wave compensation trestle 1.

[0070] In one implementation, such as Figure 2 As shown, a hoisting winch 14 is provided at the end of the trestle body 130 away from the cylinder 134 for hoisting goods.
