[0002] Against the backdrop of the booming development of the modern shipping industry, there is frequent movement of people and goods between ships and docks. As a key channel connecting ships and docks, the performance of ship gangways directly affects the efficiency and safety of port operations.

[0003] Traditional ship gangways generally have fixed angles and lengths, making them unsuitable for complex conditions such as varying ship drafts, tidal changes, and differences in berth height. When a ship's draft changes due to cargo loading and unloading, or when encountering high or low tides, gangways with fixed angles and lengths may become suspended or excessively tilted, increasing safety hazards for personnel embarking and disembarking, potentially hindering cargo transport, and severely impacting the continuity of port operations. Existing gangway adjustment methods mostly rely on manual assistance or complex on-site modifications, which are cumbersome and inefficient, failing to meet the demands of rapid loading and unloading and frequent operations.

[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides an adjustable-angle ship gangway, comprising:

[0027] The support assembly 100 includes a base 101, a bracket 102 fixedly connected to the end of the base 101, a frame 103 rotatably mounted to the end of the bracket 102, and a support member 104 fixedly connected to the side wall of the frame 103.

[0028] The gangway assembly 200 includes a fixing plate 201 fixedly connected to the end of the support member 104, an mounting plate 202 fixedly connected to the side wall of the fixing plate 201, a main hull plate 203 slidably connected to the end of the mounting plate 202, and an auxiliary hull plate 204 slidably inserted into the side wall of the end of the main hull plate 203. The main hull plate 203 and the auxiliary hull plate 204 are the same length as the mounting plate 202.

[0029] The base 101 serves as the fundamental load-bearing component of the entire gangway, providing a stable mounting surface for the device. The bracket 102 is vertically fixed to the end of the base 101, forming a robust vertical support structure. The frame 103 is rotatably mounted on the end of the bracket 102 via high-precision bearings, allowing for flexible rotation and ensuring smooth gangway angle adjustment. The support member 104 is fixedly connected to the side wall of the frame 103, supporting the gangway assembly 200. The fixing plate 201 is fixedly connected to the end of the support member 104, serving as the connection hub for the gangway assembly and ensuring a stable connection with the support assembly 100. The mounting plate 202 is fixed to the side wall of the fixing plate 201 and contains internal transmission components. The main hull plate 203 and the auxiliary hull plate 204 are the same length as the mounting plate 202, allowing for linear sliding along the length of the mounting plate 202 to adapt to different docking requirements.

[0030] Specifically, a timing belt 205 is rotatably mounted inside the mounting plate 202. The side wall of the timing belt 205 is provided with a rack structure, and a sliding member 206 is fixedly connected to the lower side wall of the main hull plate 203. The rack on the side wall of the timing belt 205 meshes with the rack on the side wall of the sliding member 206.

[0031] Driven by the synchronous belt 205 inside the mounting plate 202, the main hull plate 203 and the auxiliary hull plate 204 can slide linearly along the length of the mounting plate 202.

[0032] Furthermore, a motor 207 is bolted to the outside of the mounting plate 202, and the output shaft of the motor 207 is connected to the drive shaft of the synchronous belt 205 via a coupling.

[0033] The motor 207 is firmly connected to the outside of the mounting plate 202 by bolts, and its output shaft end is connected to the drive shaft of the synchronous belt 205 through a high-precision coupling, providing stable power for the rotation of the synchronous belt 205.

[0034] Furthermore, the side wall of the auxiliary hull plate 204 is threaded with a pin rod 208, the end of which is inserted into the positioning hole on the side wall of the main hull plate 203.

[0035] The pin 208 on the side wall of the auxiliary hull plate 204 is installed by a threaded connection. Its end can be precisely inserted into the positioning hole on the side wall of the main hull plate 203, so as to realize the stable splicing and disassembly of the main hull plate 203 and the auxiliary hull plate 204.

[0036] Preferably, a support base 105 is fixedly connected to the side wall of the base 101, and a turntable 106 is fixedly connected to the side wall of the frame 103. The end of the support base 105 is provided with an arc-shaped surface structure that cooperates with the side wall of the turntable 106.

[0037] The support base 105 has an arc-shaped surface structure at its end that works in conjunction with the side wall of the turntable 106. The two fit together to provide stable support for the rotation of the frame 103.

[0038] It should be noted that the support base 105 has a threaded connection to a push rod 107 on its side wall, and the end of the push rod 107 is inserted into the middle of the slot on the side wall of the turntable 106.

[0039] The top rod 107 is threaded to the side wall of the support base 105, and its end can be precisely inserted into the slot in the side wall of the turntable 106. By rotating the top rod 107, the rotation angle of the frame 103 can be precisely locked.

[0040] Preferably, a hydraulic rod 108 is hinged to the side wall of the base 101, and the end of the hydraulic rod 108 is hinged to the side wall of the turntable 106.

[0041] The hydraulic rod 108 is hinged at both ends to the side wall of the base 101 and the side wall of the turntable 106, respectively. Its extension and retraction are controlled by the hydraulic system to provide power support for the angle adjustment of the frame 103.

[0042] During use, angle adjustment is performed as follows: When the gangway angle needs to be adjusted, the hydraulic system is activated, and the hydraulic rod 108 begins to extend and retract. The extension and retraction of the hydraulic rod 108 causes the turntable 106 to rotate within the arc-shaped surface structure of the support base 105, thereby causing the frame 103 to rotate around the end of the bracket 102, thus adjusting the overall angle of the gangway. Once the angle is adjusted to the appropriate position, the top rod 107 is rotated so that its end inserts into the slot on the side wall of the turntable 106, locking the rotation angle of the frame 103 and ensuring the stability of the gangway during use.

[0043] Gangway length adjustment: Start motor 207. The output shaft of motor 207 drives synchronous belt 205 to rotate via coupling. Since the rack on the side wall of synchronous belt 205 meshes with the rack on the side wall of sliding member 206, the rotation of synchronous belt 205 drives main hull plate 203 to slide along the length direction of mounting plate 202. After main hull plate 203 slides to the appropriate position, pull out auxiliary hull plate 204 from the end side wall of main hull plate 203, so that auxiliary hull plate 204 and main hull plate 203 are spliced ​​to form a complete gangway. Then screw pin 208 into the side wall of auxiliary hull plate 204, so that its end is inserted into the positioning hole on the side wall of main hull plate 203, thus completing the adjustment and fixing of gangway length.

[0044] In summary, the cooperation of hydraulic rod 108 and push rod 107 allows for flexible adjustment of the gangway angle within a wide range, adapting to changes in ship draft and dock height, thus greatly improving the gangway's versatility and adaptability to various application scenarios. The main hull plate 203 is driven by a synchronous belt 205 and rack and pinion transmission, and the main hull plate 203 and auxiliary hull plate 204 are quickly connected and disassembled via pin rod 208. This makes gangway length adjustment simple and quick, allowing for rapid adjustment according to actual needs and improving work efficiency. The support assembly 100 uses high-strength steel and an optimized mechanical structure design, combined with high-precision bearings and mechanical connections, ensuring the stability and safety of the gangway during use. The synchronous belt drive system and pin locking structure of the gangway assembly 200 ensure the accuracy and reliability of gangway length adjustment, effectively preventing loosening or displacement during use.
