The limiting seat 3 is arranged on the ship's side structure 100. The hanging beam 21 in the storage position can be abutted against the limiting seat 3 to avoid the side aisle 200. The limiting seat 3 can be fixedly connected to the ship's side structure 100 by bolts, and the limiting seat 3 can also be fixedly connected to the ship's side structure 100 by welding. The locking structure 5 is used to lock the hanging beam 21 in the storage position. The locking structure 5 includes a locking seat 51 and a locking pin 52. The locking pin 52 is movably arranged on the locking seat 51. The hanging beam 21 is provided with a locking ring 25, and the locking pin 52 can be inserted into the locking ring 25.

[0036] After the hoisting is completed, the hanging beam 21 swings from the working position to the storage position and abuts against the limiting seat 3, which can avoid affecting the normal use of the side aisle 200. By arranging the locking structure 5 on the limiting seat 3, it can further avoid the hanging beam 21 in the storage position from shaking and affecting the normal use of the side aisle 200. Manually or automatically operating the locking pin 52 can complete the locking and unlocking of the hanging beam 21. The operation is convenient, the structure is simple, and the cost is low.

[0037] Optionally, the locking pin 52 is slidably arranged on the locking seat 51. The locking pin 52 has a locking position and an unlocking position. The locking pin 52 can slide from the unlocking position to the locking position. The locking pin 52 in the locking position can be inserted into the locking ring 25, and the locking pin 52 in the unlocking position is not inserted into the locking ring 25. The locking pin 52 moves in a sliding manner, which can ensure the stable switching between the unlocking function and the locking function. The driving method is simple and can be directly operated manually or automatically by a cylinder.

[0038] Optionally, the locking pin 52 can rotate relative to the locking seat 51 to keep the locking pin 52 in the locking position. When the locking pin 52 rotates, it can be blocked by the stopper of the locking seat 51, so that the locking pin 52 is kept in the locking position. Optionally, the locking pin 52 is arranged on the locking seat 51 in the vertical direction, and the locking pin 52 can be kept in the unlocking position under the action of its own gravity. The structure is simple and the cost is low.

[0039] To avoid impact damage to the hanging beam 21 and the limit seat 3, optionally, a buffer block 31 is arranged on the limit seat 3, and the hanging beam 21 in the storage position can be in contact with the buffer block 31. By buffering the impact between the hanging beam 21 and the limit seat 3 through the buffer block 31, the service life of the hanging beam 21 and the limit seat 3 can be effectively extended.

The hanging beam 21 can swing between the working position and the storage position. Since the hanging beam 21 is rotatably arranged on the base 1, when hoisting goods, the hanging beam 21 swings from the storage position to the working position. After the hoisting is completed, the hanging beam 21 swings from the working position to the storage position and abuts against the limit seat 3 to avoid affecting the normal use of the side passage 200.

[0041] To avoid the hanging beam 21 shaking in the working position and affecting the hoisting operation, optionally, a first positioning hole is arranged on the base 1, a positioning pin 4 is inserted through the first positioning hole, a plurality of second positioning holes are arranged on the hanging beam 21, and the positioning pin 4 cooperates with any one of the plurality of second positioning holes. There are a plurality of working positions, and the plurality of working positions correspond to the plurality of second positioning holes one by one. Through the plurality of working positions, the hoisting operation of the hanging beam 21 at multiple angles relative to the ship's side can be realized, which can minimize the workload of manually handling goods and adapt to more usage scenarios. The positioning of the plurality of working positions of the hanging beam 21 is achieved by inserting the positioning pin 4 into the hole, which is simple, intuitive and convenient to operate.

[0042] Optionally, a driving motor is provided on the base 1, and the driving motor is used to drive the hanging beam 21 to rotate.

[0043] This embodiment also provides a side lifting device, including a hanging beam 21 and the above-mentioned limiting structure. After the lifting is completed, the hanging beam 21 swings from the working position to the storage position and abuts against the limiting seat 3, which can avoid affecting the normal use of the side aisle 200. By providing a locking structure 5 on the limiting seat 3, it can further prevent the hanging beam 21 in the storage position from shaking and affecting the normal use of the side aisle 200. Manually or automatically operating the locking pin 52 can complete the locking and unlocking of the hanging beam 21, with convenient operation, simple structure and low cost.

[0044] The side lifting device further includes a base 1 and a hanging component 2. The base 1 is arranged on the ship side structure 100.

[0045] Setting the base 1 on the ship side structure 100 facilitates the installation of the hanging component 2. Since the hanging beam 21 is rotatably arranged on the base 1, when lifting goods, the hanging beam 21 swings from the storage position to the working position, releasing the traction force of the towing rope 23. Under the action of the gravity of the hook 24, the towing rope 23 drives the hook 24 to descend. Since the towing rope 23 is wound around the pulley 22, the pulley 22 can reduce the movement resistance of the towing rope 23. Then, goods are loaded through the hook 24, the traction force of the towing rope 23 is applied, the towing rope 23 drives the hook 24 to rise, and then the goods are unloaded through the hook 24. The goods handling efficiency is high, time and labor are saved, the potential safety hazard is small. After the lifting is completed, the hanging beam 21 swings from the working position to the storage position and abuts against the limiting seat 3 to avoid affecting the normal use of the side aisle 200.

The reduction motor 27 is used to drive the drum of the winch 28 to rotate. One end of the towing rope 23 is wound around the drum, and the other end is connected to the hook 24. The output shaft of the reduction motor 27 drives the drum to rotate, and the release and tightening of the towing rope 23 are realized through the rotation of the drum. The winch 28 is located directly above the hanging beam 21, and the reduction motor 27 is located on one side of the winch 28, which is convenient for the reduction motor 27 to directly drive the drum of the winch 28 to rotate.

[0047] To facilitate the installation of the pulley 22, optionally, one end of the hanging beam 21 is rotatably connected to the base 1, and the other end is provided with a mounting bracket 26. The pulley 22 is rotatably arranged on the mounting bracket 26. The base 1 is provided with a connecting shaft 11, and the hanging beam 21 is in rotational cooperation with the connecting shaft 11.
