[0001] The present invention relates to the technical field of shipbuilding, and in particular to a ship pier leveling method and a ship pier leveling system. Background Art

[0002] Ship docking refers to the process of a ship landing or lowering onto a dock pier after entering a dock. Ship docking is a key step in ship maintenance and construction, and its purpose is to provide stable and reliable support for the ship, facilitating subsequent construction or repair operations. During the docking process, the ship needs to adjust its posture and position to ensure that the hull is level after docking.

[0051] like Figure 1As shown, the present invention provides a method for leveling a ship pier, which includes: S1, arranging support frames 1 at positions on both sides of the bottom of the dock corresponding to the hull 100; S2, towing the hull 100 to the dock, draining the water in the dock, and allowing the hull 100 to fall onto the pier 200 and the support frame 1 at the bottom of the dock; S3, adjusting the height of the support frame 1 to make the hull 100 in a horizontal state; S4, arranging a pad in the gap between the hull 100 and the pier 200; S5, supporting a high-position support plate 2 between the two sides of the hull 100 and the bottom of the dock. In this embodiment, a support frame 1 is first set in the dock chamber. The support frame 1 is used to support the hull 100 together with the dock pier 200. The support frame 1 is set on both sides of the hull 100. Then the hull 100 is towed into the dock chamber and drained. The hull 100 will fall and land on the dock pier 200 at the bottom of the dock chamber and the support frames 1 on both sides, thereby completing the landing. Then, according to the actual landing situation of the hull 100, the height of the support frames 1 on both sides is adjusted to eliminate the height difference on both sides of the hull 100, so that The hull 100 is in a horizontal state; then, pads are stuffed into the gap created between the hull 100 and the dock 200 during the adjustment process, so that the hull 100 can always be stably pressed against the dock 200, preventing the hull 100 from continuing to fall or deflect during the subsequent construction and maintenance process. In addition, since high-position support plates 2 are also supported between the two sides of the hull 100 and the bottom of the dock chamber, the high-position support plates 2 can support both sides of the hull 100, further improving the stability of the hull 100 after leveling. This method of leveling a ship by pier does not require repeated adjustment using ballast water inside the hull 100. The adjustment method using the support frames 1 on both sides effectively improves the leveling efficiency and adjustment accuracy, thereby greatly improving the overall construction or maintenance speed of the ship.

[0052] Specifically, the ship pier leveling method can perform pier leveling on a complete ship after construction, and can also perform pier leveling on a half ship during construction; the support frame 1 and the high-position support plate 2 are both made of steel, and the high-position support plate 2 is supported on the upper half of both sides of the hull 100.

[0053] In order to improve the leveling accuracy of the hull 100, as Figure 1 and Figure 2 As shown, the bottom of the dock is provided with a first support group and a second support group on both sides of the corresponding hull 100, and the first support group and the second support group each include a plurality of support frames 1; the number of support frames 1 of the first support group and the support frames 1 of the second support group are the same and are provided in a one-to-one correspondence. Specifically, Figure 2The hull 100 is made transparent in order to clearly show the support frame 1 under the hull 100; the first support group and the second support group are symmetrically arranged at the bottom of the dock chamber with respect to the hull 100, and each support group includes a plurality of support frames 1 arranged at intervals along the length of the hull 100, so that the hull 100 can be supported at different positions to facilitate precise horizontal adjustment in the later stage.

[0054] Furthermore, step S3 includes: moving the lifting device 5 to the bottom of the support frame 1; starting the lifting device 5 to drive the support frame 1 to rise. In this embodiment, the lifting device 5 is used to drive the support frame 1 to rise as a whole, thereby driving the upper ipsilateral hull to rise for leveling.

[0055] It can be understood that when the hull 100 is leveled after landing on the pier, a lifting device 5 is provided under each support frame 1; all the support frames 1 in the first support group can be lifted synchronously under the drive of the lifting device 5, and the support frames 1 at a single or local position can also be lifted according to the actual situation on site, thereby greatly improving the flexibility of adjusting the posture of the hull 100.

[0056] The lifting device 5 can be selected according to actual needs, as long as it can drive the support frame 1 to lift, and is not limited here; for example, Figure 1 As shown, the lifting device 5 is a self-propelled modular transporter, which is also called a SPMT (Self-Propelled Modular Transporter) flatbed truck. It is a heavy-duty transport tool commonly used in this field. It is mainly composed of tires, a load-bearing platform hydraulic system and a control system. The load-bearing platform can be lifted upward under the drive of the hydraulic system to lift heavy objects. The control system of the self-propelled modular transporter can receive external signals, and the staff can control the movement of the self-propelled modular transporter by remote control; specifically, after the hull 100 is dropped to the pier, the staff controls the self-propelled modular transporter to move to the bottom of the support frame 1, and controls the load-bearing platform of the self-propelled modular transporter to lift according to the actual situation on site, thereby driving the support frame 1 to rise to achieve leveling of the hull 100.

[0057] Furthermore, after step S4, it also includes: setting a pad in the gap between the support frame 1 and the bottom surface of the dock; specifically, after the support frame 1 is lifted, there will be a height difference between the support frame 1 and the bottom surface of the dock, and the staff will fill the pad between the support frame 1 and the bottom surface of the dock, so that the support frame 1 can be stably supported, thereby facilitating the removal of the lifting equipment 5 under the support frame 1.

[0058] In order to improve the stability of the support frame 1 supporting the hull 100, before step S2, the following step is further included: a first support 3 having a first abutting plane is provided at a position corresponding to the support frame 1 on the hull 100, and the first abutting plane is made to face the bottom surface of the dock chamber. Specifically, Figure 1 As shown, a first support 3 is welded to the bottom of both sides of the hull 100. The side of the first support 3 facing the bottom of the dock is a plane, namely the first abutment plane. The first abutment plane is used to abut against the support frame 1 to avoid direct abutment between the support frame 1 and the inclined side of the hull 100, thereby preventing the support from being unstable.

[0059] In order to improve the stability of the high-position support plate 2 supporting the hull 100, step S5 includes: arranging second abutments 4 with second abutment planes on both sides of the hull 100, and making the second abutment planes face the bottom surface of the dock; arranging the high-position support plate 2 between the second abutment 4 and the bottom surface of the dock, so that the two ends of the high-position support plate 2 respectively abut against the bottom surface of the dock and the second abutment plane. Specifically, as Figure 1 As shown, second supports 4 are welded to the upper positions on both sides of the hull 100. The height of the second support 4 is higher than that of the first support 3. The side of the second support 4 facing the bottom of the dock is a plane, namely the second abutment plane. The second abutment plane is used to abut with the high-position support plate 2, thereby providing a force point for the high-position support plate 2; the high-position support plate 2 can play an auxiliary supporting role for the hull 100, thereby further improving the stability of the hull 100.

[0060] This embodiment also provides a ship pier leveling system, such as Figure 1 and Figure 2 As shown, the ship dock leveling system includes a first support group, a second support group, and a lifting device 5. The first and second support groups are symmetrically arranged on the bottom of the dock chamber with respect to the hull 100. Each of the first and second support groups includes multiple support frames 1 spaced along the length of the hull 100, which are configured to vertically abut against the hull 100. The lifting device 5 is capable of driving the support frames 1 upward. In this embodiment, the ship dock leveling system adopts the aforementioned ship dock leveling method, capable of adjusting the height of both sides of the hull 100 to eliminate the height difference between the two sides of the hull 100, thereby achieving leveling of the hull 100. This ship dock leveling system has a simple structure and is easy to operate, effectively improving leveling efficiency and adjustment accuracy.

[0061] Specifically, when the hull 100 is seated, the first support group and the second support group are symmetrical about the hull 100. The first support group and the second support group both include a plurality of support frames 1 spaced apart along the length direction of the hull 100. Each support frame 1 can be lifted under the drive of the lifting device 5. Therefore, the posture of the local position of the hull 100 can be adjusted according to the actual situation on site, which greatly improves the flexibility of adjustment.

[0062] like Figure 1 As shown, the ship pier leveling system also includes a high-position support plate 2, which is symmetrically arranged on both sides of the hull 100, with one end of the high-position support plate 2 resting on the bottom surface of the dock chamber, and the other end being used to rest vertically on the hull 100; specifically, when leveling the hull 100, the staff uses the lifting equipment 5 to drive the support frame 1 to rise, thereby adjusting the posture of the hull 100; when the hull 100 reaches the required horizontal state, the staff fills the space between the hull 100 and the dock 200, and between the support frame 1 and the bottom surface of the dock chamber, thereby ensuring the stability of the adjusted hull 100, and at the same time, the staff uses the high-position support plate 2 to support the high positions on both sides of the hull 100 to further improve the stability of the hull 100; then the lifting equipment 5 is removed to facilitate the horizontal adjustment of other hulls 100.

[0063] The structure of the support frame 1 can be set according to actual needs, as long as it can achieve reliable support for the hull 100 and can move vertically under the drive of the lifting device 5; for example, Figures 3 to 5 As shown, the support frame 1 includes legs 11 and a load-bearing beam 12. The load-bearing beam 12 is fixedly connected to the legs 11, and the legs 11 are used to support the bottom surface of the dock. One side of the load-bearing beam 12 is used to abut against the hull 100, and the other side of the load-bearing beam 12 abuts against the lifting device 5. Specifically, the support frame 1 is made of steel, and the load-bearing beam 12 is arranged in a horizontal rectangular frame and welded to the legs 11. Before the lifting device 5 drives the support frame 1 up and down, the legs 11 are supported on the bottom surface of the dock, and the load-bearing beam 12 abuts against the first support platform 3 welded on both sides of the hull 100. When the lifting device 5 is used to drive the support frame 1, the output end of the lifting device 5 abuts against the load-bearing beam 12, directly driving the load-bearing beam 12 to rise, thereby driving the support frame 1 as a whole to rise. After leveling is completed, the staff fills the gap between the legs 11 and the bottom surface of the dock with pads.

[0064] In this embodiment, the lifting device 5 is a self-propelled modular transport vehicle. Before performing the leveling operation, the staff remotely controls the lifting device 5 to move it to the bottom of the load-bearing beam 12 between the legs 11; and in order to increase the structural strength of the support frame 1, a reinforcing beam 13 is welded to the load-bearing beam 12, and the reinforcing beam 13 and the load-bearing beam 12 form a Japanese-shaped structure, thereby improving the load capacity of the support frame 1.

[0065] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
