Cargo loading and unloading equipment is the core equipment for achieving efficient and safe loading and unloading of cargo in port logistics and maritime transportation. Its design directly affects ship turnaround efficiency, operating costs and cargo safety. However, existing technologies have some problems: the base size of existing cargo ship loading and unloading devices is fixed, and the device is prone to tipping over due to force imbalance when lifting heavy objects, which can damage the device and cargo, and even endanger the safety of workers. Therefore, we propose a cargo ship loading and unloading device. Utility Model Content

[0003] One objective of this invention is to provide a new technical solution for cargo ship loading and unloading devices.

[0019] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0020] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0022] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0023] like Figure 1-6 As shown, a cargo ship loading and unloading device includes a base 1 made of stainless steel. The main function of the base 1 is to support the entire device and ensure its stable operation.

[0024] Furthermore, a support rod 2 is fixedly connected to one side of the base 1. The support rod 2 is used to balance the supporting force of the base 1 and prevent the device from tipping over during movement. Both the base 1 and the support rod 2 are fixedly connected to casters 3. The casters 3 facilitate the movement of the device, allowing the device to be quickly moved to the work area.

[0025] Furthermore, a fixing rod 4 is rotatably connected to the base 1, and a fixing component 5 is provided on the base 1. The fixing component 5 is used to lock the fixing rod 4. The fixing component 5 includes a locking rod 51. A sliding groove is provided on the fixing rod 4, and the locking rod 51 is slidably connected in the sliding groove. A slot is provided on the base 1, and the locking rod 51 is engaged in the slot. A pull ring 52 is fixedly connected to one end of the locking rod 51.

[0026] Furthermore, a rotating groove is provided on the base 1, and a rotating wheel 53 is rotatably connected in the rotating groove. The locking rod 51 is slidably connected to the rotating wheel 53, and the locking rod 51 cannot be relative to the rotating wheel 53. A spring 54 is fixedly connected to the locking rod 51, and the spring 54 is fixedly connected to the rotating wheel 53.

[0027] Specifically, by pulling the pull ring 52, the locking rod 51 compresses the spring 54 and retracts into the groove of the fixing rod 4, so that the locking rod 51 is no longer stuck in the groove. At this time, the fixing rod 4 can be rotated to adjust the opening angle of the fixing rod 4. After the adjustment is completed, the pull ring 52 is released, and the locking rod 51 automatically engages in the groove through the rebound force of the spring 54 to fix the fixing rod 4. By adjusting the opening angle of the fixing rod 4, the contact range between the equipment and the ground can be expanded to form a more stable support base, avoiding the imbalance of force on the base 1 when loading and unloading goods, which could cause the equipment to tip over.

[0028] Furthermore, a telescopic rod 6 is movably connected to the fixed rod 4, a slide rail is provided on the fixed rod 4, the telescopic rod 6 is slidably connected in the slide rail, a positioning hole is provided in the inner wall of the slide rail, and a fixing hole corresponding to the positioning hole is provided on the telescopic rod 6.

[0029] Furthermore, a fixing pin 13 is movably connected inside the positioning hole, and a rotating rod 14 is rotatably connected inside the fixing pin 13. A knob 15 is fixedly connected to one end of the rotating rod 14, and a locking block 16 is fixedly connected to the other end of the rotating rod 14. A storage groove is opened inside the fixing pin 13, and the locking block 16 is rotatably connected inside the storage groove.

[0030] Specifically, by rotating the knob 15, the rotating rod 14 is driven to rotate, and the rotating rod 14 drives the locking block 16 to rotate, so that the locking block 16 is retracted into the storage slot. At this time, the locking block 16 no longer restricts the movement of the fixing pin 13. The fixing pin 13 is pulled out, and then the length of the telescopic rod 6 is adjusted. After the adjustment is completed, the fixing pin 13 is reinserted into the positioning hole and the fixing hole. Then, the knob 15 is rotated in the opposite direction so that the locking block 16 locks the fixing pin 13 again, that is, fixes the telescopic rod 6. By adjusting the length of the telescopic rod 6, when the device is loading and unloading heavy goods, the support range can be increased by extending the telescopic rod 6, the pressure can be distributed, and the equipment can be prevented from tipping over.

[0031] Furthermore, hydraulic rods 7 are fixedly connected to both the telescopic rod 6 and the base 1. The movable end of the hydraulic rod 7 is fixedly connected to the support seat 10. By controlling the extension and retraction of the hydraulic rod 7, the support seat 10 can be moved, thereby supporting the device and preventing the universal wheels 3 from contacting the ground and causing the device to move when it is working. At the same time, multiple sets of hydraulic rods 7 can be controlled independently, so that the device can adapt to uneven ground, ensuring that the base 1 remains level and preventing the device from tipping over when it is running.

[0032] Furthermore, a support column 11 is fixedly connected to the base 1, and a crossbeam 12 is fixedly connected to the support column 11. A hoisting assembly 8 is provided on one side of the crossbeam 12. The hoisting assembly 8 includes a hoisting seat 81. A slide rail is provided on one side of the crossbeam 12. The hoisting seat 81 is slidably connected in the slide rail. A first motor 82 is fixedly connected to one side of the hoisting seat 81. A pulley 83 is fixedly connected to the output end of the first motor 82. The pulley 83 is rotatably connected in the slide rail.

[0033] Furthermore, the hoisting assembly 8 also includes a second motor 84, which is fixedly connected to the hoisting base 81. The output end of the second motor 84 is fixedly connected to a rotating shaft 85, which is rotatably connected to the hoisting base 81. A steel cable 86 is wound around the rotating shaft 85, and a hook 87 is fixedly connected to one end of the steel cable 86.

[0034] Specifically, during cargo loading and unloading, the first motor 82 is started to drive the pulley 83 to rotate, moving the lifting platform 81 to the cargo location. Then, the second motor 84 is started to drive the rotating shaft 85 to rotate, causing the steel cable 86 to be wound or released, so that the hook 87 can lift the cargo. After that, the first motor 82 is started again to move the lifting platform 81 to transport the cargo to the designated location. The above-mentioned lifting operation is a mature existing technology, and it is believed that those skilled in the art are already very familiar with it, so it will not be described in detail here.

[0035] Furthermore, a balancing component 9 is provided on the other side of the crossbeam 12. The balancing component 9 includes a counterweight 91. An adjustment groove is provided on the other side of the crossbeam 12. The counterweight 91 is slidably connected in the adjustment groove. A lead screw 92 is rotatably connected in the adjustment groove. The lead screw 92 is threadedly connected to the counterweight 91. A third motor 93 is fixedly connected to the crossbeam 12. The lead screw 92 is fixedly connected to the output end of the third motor 93.

[0036] Specifically, after the third motor 93 starts, it drives the lead screw 92 to rotate. After the lead screw 92 rotates, the counterweight 91 will slide in the adjustment groove under its threaded engagement, thereby changing the position of the counterweight 91. This allows the device to adjust the position of the counterweight 91 according to the weight of the goods to be loaded or unloaded, thus preventing the device from tipping over due to heavy loads.

[0037] The aforementioned cargo ship loading and unloading device expands the contact range between the equipment and the ground by adjusting the opening angle of the device fixing rod 4 and the extension length of the telescopic rod 6, forming a more stable support base and preventing the base 1 from becoming unbalanced during loading and unloading, thus avoiding the device tipping over.

[0038] This utility model is equipped with a fixing component 5 and a fixing pin 13. By pulling the pull ring 52, the locking rod 51 compresses the spring 54 and retracts into the groove of the fixing rod 4, so that the locking rod 51 is no longer stuck in the groove. At this time, the fixing rod 4 can be rotated to adjust the opening angle of the fixing rod 4. After the adjustment is completed, the pull ring 52 is released, and the locking rod 51 automatically engages in the groove through the rebound force of the spring 54, fixing the fixing rod 4. By adjusting the opening angle of the fixing rod 4, the rotating rod 14 is driven to rotate by rotating the knob 15. The rotating rod 14 then drives the locking block 16 to rotate, so that the locking block 16 is retracted into the storage groove. At this time, the locking block 16 no longer restricts the movement of the fixing pin 13. The fixing pin 13 is pulled out, and then the length of the telescopic rod 6 is adjusted. After the adjustment is completed, the fixing pin 13 is reinserted into the positioning hole and the fixing hole. Then, the knob 15 is rotated in the opposite direction to make the locking block 16 lock the fixing pin 13 again, that is, fix the telescopic rod 6.

[0039] This utility model is equipped with a balancing component 9. After the third motor 93 is started, it drives the lead screw 92 to rotate. After the lead screw 92 rotates, the counterweight 91 will slide in the adjustment groove under its thread engagement, thereby changing the position of the counterweight 91. In this way, the device can adjust the position of the counterweight 91 according to the weight of the goods to be loaded or unloaded, thereby avoiding the device from tipping over due to heavy loading or unloading of goods.
