[0003] With the rise of flat-land shipbuilding, horizontal transfer and launching from floating docks has become a new trend. However, when docking with a dock platform for ship transfer operations, there are strict requirements for the height difference between the floating dock and the dock platform. Existing total stations are commonly used to position and level the floating dock and the dock platform. However, for floating dock operators, using total stations requires repeated feedback of measurement results, which are then fed back to the loading control personnel by the ship operators. This results in delayed and interfering measurement results for the loading control personnel.

[0030] The following describes the implementation of the present application through specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present application from the disclosure herein. The present application may also be implemented or operated through various other specific implementations, and the details of the present application may be modified or altered based on different viewpoints and applications without departing from the spirit of the present application.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, the terms "first" and "second" are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0032] According to one aspect of the present application, a leveling auxiliary tool for docking a floating dock with a dock platform is provided, which is arranged on the floating dock or the dock platform. The leveling auxiliary tool specifically includes a ruler assembly 100 and an indicator assembly 200.

[0033] The scale assembly 100 is mounted on the dock platform and includes a first base 110 and a scale 120. The first base 110 is used to secure the scale 120. The scale 120 is provided with evenly spaced graduations, and the graduations extend perpendicularly to the dock platform surface, thereby marking the height above the dock platform. The indicator assembly 200 is located on the floating dock and includes a fixing bracket 210 and an indicator rod 220. The fixing bracket 210 is used to secure the indicator rod 220, ensuring that the indicator rod 220 is parallel to the dock surface and that the end of the indicator rod 220 points perpendicularly to the direction of the graduations on the scale 120.

[0034] The working principle of the leveling auxiliary tooling is that, by utilizing the mutual cooperation between the scale assembly 100 arranged on the dock platform and the indicator assembly 200 arranged on the floating dock, when the ship is transferred from the dock platform to the floating dock, the indicator rod 220 of the indicator assembly 200 can always point to the scale mark on the scale assembly 100, and according to the scale mark value pointed by the indicator rod 220, the height difference between the floating dock and the dock platform is fed back in real time, so as to quickly judge whether the floating dock and the dock platform meet the transfer conditions, and when the height difference between the floating dock and the dock platform exceeds the transfer conditions, the draft depth of the floating dock can be quickly adjusted until the scale mark on the scale 120 pointed by the indicator rod 220 is kept within the preset range.

[0035] In one embodiment, the first base 110 includes a first horizontal portion 111 and a first vertical portion 112. The first horizontal portion 111 is located on the dock platform and is used to support the first vertical portion 112. One end of the first vertical portion 112 is fixed to the surface of the first horizontal portion 111, and the other end thereof extends upward in a direction perpendicular to the surface of the first horizontal portion 111, thereby fixing the scale 120 on the first vertical portion 112 and also extending upward in a direction perpendicular to the surface of the first horizontal portion 111.

[0036] In one embodiment, the ruler assembly 100 further includes a second base 130 that is sleeved around the periphery of the first vertical portion 112 and movably connected to the first vertical portion 112. The second base 130 is used to support the ruler 120 and maintain a preset distance between the bottom of the ruler 120 and the surface of the dock platform. In other words, by adjusting the position of the second base 130 on the first vertical portion 112, the distance between the bottom of the ruler 120 and the surface of the dock platform can be adjusted, thereby freely controlling the actual distance between the zero point of the ruler 120 and the surface of the dock platform. This facilitates determining the height difference between the floating dock and the dock platform when the zero point on the ruler 120 is used as a leveling reference for the two platforms.

[0037] Preferably, the second base 130 includes a vertically connected support portion and a raised portion, and the support portion is provided with a through hole adapted to the first vertical portion 112. The scale 120 is located on the support portion between the first vertical portion 112 and the raised portion to provide support for the bottom of the scale 120. The design of the raised portion can also prevent the bottom of the scale 120 from sliding off the edge of the support portion.

[0038] Furthermore, the raised portion is provided with a plurality of notches, which can ensure that when the second base 130 supports the bottom of the scale 120, the raised portion will not completely block the scale marks at the bottom of the scale 120, so that the operator can observe the actual scale data at the bottom of the scale 120 through the notches.

[0039] Preferably, a slot and graduated markings are provided at the end of the first vertical portion 112 proximal to the first horizontal portion 111. The bottom of the second base 130 is movably connected to the first vertical portion 112 via bolts and nuts, thereby supporting the second base 130 and maintaining a predetermined distance between the bottom of the second base 130 and the surface of the dock platform. Adjusting the actual position of the bolts and nuts within the slots controls the height of the second base 130 from the dock platform surface.

[0040] In one embodiment, the fixed bracket 210 includes a second horizontal portion 211 and two second vertical portions 212 vertically arranged on the surface of the second horizontal portion 211. The two second vertical portions 212 are arranged in parallel and at intervals on the second horizontal portion 211 and are fixedly connected by a cross bar. The indicator rod 220 is fixed at the same height on the two second vertical portions 212, and the indicator rod 220 is kept level with the floating dock.

[0041] Preferably, the indicator rod 220 vertically passes through the two second vertical portions 212 so that the indicator rod 220 can maintain a preset distance from the surface of the floating dock.

[0042] On the other hand, the present application also provides a method for docking and leveling a floating dock and a dock platform, which includes using any of the above-mentioned auxiliary leveling tooling, and specifically may include the following steps:

[0043] First, install the indicator assembly 200 at the preset position of the floating dock, and install the scale assembly 100 at the preset position of the corresponding dock platform, and make the indicator rod 220 of the indicator assembly 200 point to the scale mark of the scale assembly 100. Among them, the installation position of the auxiliary tooling must at least correspond to the port and starboard sides of the floating dock. In other words, at least two sets of leveling auxiliary tooling are required, one for the preset position of the floating dock's port side and the corresponding left-hand dock platform, and the other for the preset position of the floating dock's starboard side and the corresponding starboard dock platform.

[0044] For example, in this embodiment, the first indicator assembly can be installed at a preset position on the port side of the floating dock, and the first scale assembly can be installed at a preset position on the dock platform corresponding to the port side, with the indicator rod 220 of the first indicator assembly pointing to the 0 scale mark of the first scale assembly. Then, the second indicator assembly can be installed at a preset position on the starboard side of the floating dock, and the second scale assembly can be installed at a preset position on the dock platform corresponding to the starboard side, with the indicator rod 220 of the second indicator assembly pointing to the 0 scale mark of the second scale assembly. By pointing the first indicator assembly on the port side and the second indicator assembly on the starboard side to the 0 scale marks of the corresponding scale assemblies, respectively, it can be ensured that the port and starboard sides of the floating dock always remain relatively level when docked with the dock platform.

[0045] Then, the floating dock loading personnel adjust the draft of the floating dock ballast tank according to the scale mark value pointed by the indicator rod 220 of the indicator assembly 200 until the floating dock and the dock platform meet the height difference requirement for ship transfer.

[0046] For example, in this embodiment, the floating dock maneuvering personnel can monitor the scale mark value of the indicator rod 220 pointing to the scale assembly 100 in real time based on the monitoring devices installed on the port and starboard sides of the floating dock. When the scale mark value of the indicator rod 220 pointing to the scale assembly 100 exceeds the transfer height difference range, the ballast tank draft can be appropriately adjusted. Specifically, when the scale mark value of the indicator rod 220 pointing to the scale assembly 100 is a positive value, it indicates that the floating dock surface baseline is higher than the dock platform baseline. In other words, the ballast pump can be adjusted to increase the draft of the floating dock, thereby aligning the floating dock surface baseline with the dock platform baseline. Conversely, when the scale mark value of the indicator rod 220 pointing to the scale assembly 100 is a negative value, it indicates that the floating dock surface baseline is lower than the dock platform baseline. In other words, the ballast pump can be adjusted to reduce the draft of the floating dock, thereby aligning the floating dock surface baseline with the dock platform baseline. That is to say, the transshipment task can only be carried out after the floating dock and the dock platform meet the height difference requirements for ship transshipment (the scale mark value of the indicator rod 220 pointing to the scale assembly 100 remains within the preset range) until the ship moves to the designated position of the floating dock and completes the landing.

[0047] The present application provides an auxiliary tooling and leveling method for docking and leveling a floating dock and a dock platform, comprising a ruler assembly 100 and an indicator assembly 200. By utilizing the mutual cooperation of the ruler assembly 100 arranged on the dock platform and the indicator assembly 200 arranged on the floating dock, when a ship is transferred from the dock platform to the floating dock, the indicator rod 220 of the indicator assembly 200 can always point to the scale mark on the ruler assembly 100, and according to the scale mark value pointed by the indicator rod 220, the height difference between the floating dock and the dock platform is fed back in real time, thereby quickly judging whether the floating dock and the dock platform meet the transfer conditions, and when the height difference between the floating dock and the dock platform exceeds the transfer conditions, the draft depth of the floating dock can be quickly adjusted so that the scale mark on the ruler pointed to by the indicator rod 220 remains within a preset range, thereby realizing convenient and fast leveling between the floating dock and the dock platform.

[0048] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
