Technical Field

[0001] This utility model relates to a loading and unloading device, specifically a lifting port quick loading and unloading device, belonging to the field of mechanical structure design technology. Background Technology

[0002] During sea voyages, crew members need sufficient food and supplies to meet their basic living needs. To ensure the crew's normal work and life at sea, before setting sail, a large amount of food such as rice, vegetables, and milk, as well as some daily necessities, are loaded into the ship's hold; upon returning, a large number of items such as vegetable baskets and garbage are unloaded. The loading and unloading work is heavy and requires a lot of manpower.

[0003] Currently, the loading, unloading, and replenishment of food and other supplies all rely on manual labor by crew members inside the elevator shaft. This method has the following problems:

[0004] (1) Inefficient: Manual loading and unloading of supplies requires crew members to manually move and stack materials, which is time-consuming and labor-intensive; for example, during a 60-day voyage, it would take about 18 hours to load the required items if the crew worked non-stop.

[0005] (2) Unable to meet the requirements of modern voyage logistics support: Modern ships have increasingly higher requirements for loading, unloading and replenishment, requiring efficient, accurate and reliable replenishment of materials. In addition, the size and carrying capacity of modern ships are constantly increasing, requiring a larger amount of replenishment materials, while manual loading and unloading methods often cannot meet the needs of such large-scale replenishment.

[0021] Figure 1 This is a schematic diagram of the loading and unloading device of this utility model;

[0022] Among them: 1-motor, 2-drive sprocket, 4-hook, 5-materials, 6-protective cover, 7-lifting port, 8-transmission chain, 9-driven sprocket, 10-support frame. Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] This embodiment, taking into account the structural characteristics of ship elevators, provides a practical and efficient loading and unloading device to automate the loading and unloading of materials on board.

[0025] like Figure 1 As shown, the loading and unloading device includes: a motor 1, a chain drive mechanism, and a support frame 10. The chain drive mechanism includes a driving sprocket 2, a driven sprocket 9, and an annular transmission chain 8 wound around the driving sprocket 2 and the driven sprocket 9, respectively. The transmission chain 8 meshes with the driving sprocket 2 and the driven sprocket 9.

[0026] The support frame 10 includes three telescopic support rods. One end of each rod is connected to a three-dimensional support via a pin, arranged in a regular triangular pyramid shape (i.e., the three support rods are evenly distributed along the circumference of the three-dimensional support). The support rods can rotate around the pins to open at different angles as needed, so that their other ends can be supported on the upper deck. Each support rod end is connected to an anti-slip pad to prevent the support frame 10 from slipping. Due to the unevenness of the upper deck, the anti-slip pads are movably connected to the ends of the support rods and can adjust their posture according to the supported position to ensure that the support frame 10 can be reliably supported on the upper deck.

[0027] Motor 1 is fixed to the floor inside the cabin with screws and provides power to the chain drive mechanism. The drive shaft of motor 1 is rigidly connected to the drive sprocket 2. The motor can be controlled by both wireless and wired remote control and can achieve forward and reverse operation. The speed adjustment knob on motor 1 can adjust the motor speed within a certain range. The chain drive mechanism is set vertically, with the driven sprocket 9 suspended from the bottom of the three-dimensional support. The drive chain 8 passes through the lifting port 7 (to avoid affecting the escalator inside the lifting port, the drive chain 8 passes through the front and rear sides of the escalator inside the lifting port 7), thus enabling the loading and unloading of materials 5 without disassembling the escalator inside the lifting port 7.

[0028] The transmission chain 8 is provided with connecting parts (such as hooks 4) at equal intervals for hanging materials 5. The materials 5 are loaded / unloaded through the hooks 4. At the same time, the transmission chain 8 is provided with detachable spare links. The spare links are the same as the links that form the transmission chain 8. They are used to adjust the length of the transmission chain 8 or to replace damaged links in the transmission chain 8.

[0029] The workflow is as follows: After the device is assembled, when loading materials, two crew members take their positions on the upper deck and the cabin floor, respectively. The motor 1 is started, and the transmission chain 8 rotates counterclockwise at a certain speed under the drive of the motor 1. The crew member on the upper deck hangs the items to be loaded on the hook 4. The items descend with the transmission chain 8. When the items reach the cabin floor, the personnel on the cabin floor remove the items during the descent, thus completing the loading of the items. This process can be repeated continuously.

[0030] When unloading supplies, motor 1 is started, and the transmission chain 8 rotates clockwise at a certain speed under the drive of motor 1. The crew members on the cabin floor hang the items to be unloaded on hooks, and the items rise with the chain until they reach the upper deck. The personnel on the upper deck take down the items, thus completing the unloading of the items. This process can be repeated continuously.

[0031] In addition, to ensure the reliability of the loading / unloading process, a protective cover 6 (a canvas cover is used in this embodiment) is installed at the lifting port 7 to protect the lifting port 7, and the transmission chain 8 carrying the materials 5 passes through the protective cover 6.

[0032] In addition, storage bags are provided for storing small, scattered items. These small, scattered items are placed inside the storage bags, and the bags containing the items are hung on hook 4 during loading / unloading.

[0033] Using this device for mechanical loading and unloading of materials results in high efficiency (more than 80% higher than manual labor) and can reduce the physical labor intensity of crew members.

[0034] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
