Description

Technical Field

[0001] This utility model relates to the field of cargo loading technology, and in particular to a port cargo loading device. Background Technology

[0002] When loading powdered cargo onto ships at the port, the powdered cargo is often placed in tonnes, and then a crane is used to lift the tonnes. During lifting, the spreader is attached to the hook with a wire rope, and then the sling is passed through the sling of the tonne and attached to the hook at the bottom of the spreader. The crane can then lift the tonne to the cargo ship, and then the sling is removed from the hook at the bottom of the spreader to separate the sling from the tonne.

[0003] In common port cargo loading devices, the sling is passed through the sling of the ton bag, and the end of the sling is hooked onto the bottom hook of the spreader. The crane can then lift the ton bag to load the cargo onto the ship. After the ton bag is lifted onto the cargo ship, the end of the sling needs to be removed from the bottom hook of the spreader. After each ton bag is lifted onto the cargo ship, the crane operator must remove the end of the sling from the hook of the spreader one by one. This removal operation takes a long time. When lifting a large number of ton bags, the lifting efficiency needs to be improved. Therefore, this application provides a port cargo loading device to meet the needs. Utility Model Content

[0004] This utility model provides a port cargo loading device to solve the problem of needing to improve hoisting efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A port cargo loading device includes a spreader and slings, and further includes: The attachment mechanism includes multiple fixed plates and multiple guide sleeves fixed to the bottom of the lifting device. Fixed hooks are fixed to the sides of the fixed plates, and movable hooks are slidably connected to the inner walls of the guide sleeves. Hangers are provided at both ends of the sling. Two hangers on the same sling are respectively attached to the fixed hooks and the movable hooks. The ends of the multiple movable hooks are connected to a moving component, which is used for the displacement of the movable hooks within the guide sleeves.

[0006] Preferably, the end of the fixing hook away from the fixing plate is bent into a bent portion, and the bent portion curves upward.

[0007] Preferably, the movable hook has a hanging groove, and the hanging item is hung in the hanging groove.

[0008] Preferably, the inner wall of the hanging groove has a series of connected inclined surfaces and a flat surface, and the hanging piece is hung on the flat surface.

[0009] Preferably, a guide plate is fixed to the side of the hanger, and the guide plate is in contact with the inclined surface.

[0010] Preferably, the moving component includes a guide seat fixed to the bottom of the lifting device, a guide rod slidably connected inside the guide seat, a long rod fixed to the end of the guide rod, multiple movable hooks fixed to the side of the long rod away from the guide rod, and a spring fixed between the long rod and the guide seat, the spring being sleeved on the guide rod.

[0011] Preferably, the side of the hanger has a through groove, and the bent end of the sling hangs in the through groove.

[0012] Preferably, an arc-shaped plate is fixed to the side of the hanging piece corresponding to the through groove, the arc-shaped plate is in contact with the inner wall of the bend at the end of the sling, and the side of the arc-shaped plate is wound with a winding part.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting fixed hooks and movable hooks, one end of the sling is hung on the fixed hook, and the other end passes through the sling of the ton bag and is hung on the movable hook. After the ton bag is lifted onto the cargo ship, multiple movable hooks are moved simultaneously by the moving component, so that multiple hooks are separated from multiple ends of the sling at the same time. After separation, the spreader can be pulled upward, so that the spreader pulls the sling and the ton bag apart. There is no need to manually contact the connection between the sling and the spreader one by one, which greatly improves the lifting efficiency of the ton bag and is suitable for large-volume lifting.

[0014] By setting up a long rod and a guide rod, pulling the guide rod causes the long rod to move multiple movable hooks simultaneously, which can then connect one end of the sling to the lifting device, making it easy to use.

[0015] By setting up a hanging groove and a guide plate, when the movable hook moves, the inclined surface of the inner wall of the hanging groove squeezes the guide plate, causing the guide plate to drive the hanging part upward. Then the movable hook separates from the hanging part, and after separation, it can contact the connection between the sling end and the lifting device. Through the cooperation of the hanging groove and the guide plate, the hanging stability of the hanging part on the movable hook is improved, and when the movable hook separates from the hanging part, the jamming of the hanging part on the movable hook is reduced, so that the separation action of the hanging part from the movable hook is stable.

[0016] By incorporating an arc-shaped plate and a winding section, the arc-shaped plate increases the contact area between the sling bend and the hanger, thus preventing damage caused by excessive pressure at the connection point due to a small contact area. At the same time, the winding section prevents sharp edges on the sides of the arc-shaped plate from scratching the inner wall of the sling bend, extending the service life of the sling.

[0019] The following is a detailed description of a port cargo loading device provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0020] like Figures 1-6 As shown, an embodiment of this utility model provides a port cargo loading device, including a spreader 1 and a sling 2, and further including: a hooking mechanism 3, the hooking mechanism 3 including multiple fixed plates 4 and multiple guide sleeves 7 fixed to the bottom of the spreader 1, fixed hooks 5 fixed to the sides of the fixed plates 4, movable hooks 9 slidably connected to the inner walls of the guide sleeves 7, hanging parts 14 provided at both ends of the sling 2, two hanging parts 14 on the same sling 2 respectively hooking onto the fixed hooks 5 and the movable hooks 9, and the ends of the multiple movable hooks 9 are connected to a moving component, the moving component being used for movable hooking The displacement of hook 9 within guide sleeve 7; spreader 1 is the load-bearing component for lifting, receiving power from the crane and driving the lifting and lowering of the ton bag; sling 2 is used to connect spreader 1 and ton bag; fixed plate 4 provides a stable installation base for fixed hook 5, ensuring reliable connection at the fixed end; guide sleeve 7 restricts the movement trajectory of movable hook 9, ensuring smooth sliding; hanger 14 enables rapid connection of sling 2 with fixed hook 5 and movable hook 9; moving component can synchronously drive the displacement of multiple movable hooks 9, achieving batch unhooking without manual operation, significantly improving the efficiency of large-volume ton bagging in ports.

[0021] like Figure 3As shown in this embodiment, the end of the fixed hook 5 away from the fixed plate 4 is bent into a bent part 6. The bent part 6 is curved upward, and the curved part 6 forms an anti-detachment blocking structure. When the hanging part 14 at the end of the sling 2 is hung on the fixed hook 5, the bent part 6 can prevent the hanging part 14 from accidentally sliding off under the action of hoisting vibration or inertia, thus ensuring the safety of the fixed end connection.

[0022] like Figure 4 and Figure 5 As shown in this embodiment, the movable hook 9 has a hanging groove 10, and the hanging part 14 is hung in the hanging groove 10. The hanging groove 10 provides a precise hanging and positioning space for the hanging part 14, so that the hanging part 14 can be stably hung on the movable hook 9, and avoids the hanging part 14 from shifting due to shaking during the hoisting process.

[0023] like Figure 4 and Figure 5 As shown in this embodiment, the inner wall of the hanging groove 10 is provided with a series of inclined surfaces and a flat surface. The hanging part 14 is hung on the flat surface. The flat surface structure provides a stable bearing support surface for the hanging part 14, ensuring that the hanging part 14 is subjected to uniform force during hoisting. The inclined surface structure plays a guiding role when the hook is released. When the movable hook 9 moves, the inclined surface can squeeze the hanging part 14 to generate an upward displacement, so that the hanging part 14 can be smoothly released from the flat bearing surface, reducing the jamming phenomenon during release and ensuring smooth release action.

[0024] like Figure 4 As shown in this embodiment, a guide plate 15 is fixed to the side of the hanger 14. The guide plate 15 is in contact with the inclined surface and the inclined surface of the hanging groove 10. When the hook is released, the inclined surface applies a uniform upward force to the hanger 14 through the guide plate 15 to ensure that the hanger 14 separates from the hanging groove 10 along the preset trajectory.

[0025] like Figure 3 As shown in this embodiment, the moving component includes two guide seats 13 fixed to the bottom of the lifting device 1. A guide rod 12 is slidably connected inside the guide seat 13. A long rod 8 is fixed to the end of the guide rod 12. Multiple movable hooks 9 are fixed to the side of the long rod 8 away from the guide rod 12. A spring 11 is fixed between the long rod 8 and the guide seat 13. The spring 11 is sleeved on the guide rod 12. The guide seat 13 cooperates with the guide rod 12 to restrict the movement direction of the long rod 8 and ensure that the multiple movable hooks 9 slide synchronously and smoothly. After the spring 11 is unhooked, it can automatically drive the long rod 8 and the movable hooks 9 to reset, without the need for manual reset, making it more convenient to use.

[0026] like Figure 4 and Figure 6As shown in this embodiment, the side of the hanger 14 is provided with a through groove 16. The bent end of the sling 2 is hung in the through groove 16. The end of the sling 2 passes through the through groove 16 and is then connected to the sling 2 by sewing. The through groove 16 provides installation space for the bent end of the sling 2, so that the connection position between the sling 2 and the hanger 14 is stable and reliable.

[0027] like Figure 6 As shown in this embodiment, an arc-shaped plate 17 is fixed on the side of the hanger 14 corresponding to the through groove 16. The arc-shaped plate 17 is in contact with the inner wall of the bend at the end of the sling 2. A winding part 18 is wound around the side of the arc-shaped plate 17. The arc-shaped plate 17 is in contact with the inner wall of the bend of the sling 2, which can evenly distribute the force on the sling 2 to the arc surface, greatly reduce the pressure at the contact point, and prevent the sling 2 from being excessively worn or broken due to localized force concentration at the through groove 16. The winding part 18 eliminates the sharp edges of the side of the arc-shaped plate 17, preventing the sling 2 from being scratched by the edges during hoisting, and effectively extending the service life of the sling 2.

[0028] Working principle: Before hoisting, hang the hanging piece 14 at one end of the sling 2 on the fixed hook 5 at the bottom of the lifting device 1. The bent part 6 of the fixed hook 5 is tilted upward to prevent the hanging piece 14 from falling off accidentally. After passing the other end of the sling 2 through the sling of the ton bag, hang the hanging piece 14 at this end in the hanging groove 10 of the movable hook 9. The guide plate 15 on the side of the hanging piece 14 fits against the inclined surface of the inner wall of the hanging groove 10. The hanging piece 14 is hung on the plane of the hanging groove 10 to achieve a stable connection. The arc plate 17 at the through groove 16 on the hanger 14 fits against the inner wall of the bend of the sling 2, increasing the contact area to reduce pressure and prevent the sling 2 from breaking or being damaged at the through groove 16 after being stressed. The winding part 18 on the side of the arc plate 17 avoids sharp edges from scratching the sling 2 and extends the service life of the sling 2. After starting the crane and using the spreader 1 to lift the ton bag to the designated position on the cargo ship, pull the guide rod 12 of the moving component. The guide rod 12 slides in the guide seat 13 and drives the long rod 8 to move. The long rod 8 simultaneously pulls multiple movable hooks 9 to slide in the guide sleeve 7. The spring 11 is compressed by the long rod 8. When the movable hook 9 moves, the inclined surface of the inner wall of the hanging groove 10 presses the guide plate 15, causing the guide plate 15 to drive the hanging part 14 to move upward, so that the hanging part 14 is separated from the plane of the hanging groove 10, and finally the movable hook 9 and the hanging part 14 are separated. After the movable hook 9 separates from the hanger 14, pull the lifting device 1 upward. Through the cooperation of the fixed hook 5 and the hanger 14 at the other end of the sling 2, the sling 2 is pulled out from the sling of the ton bag. After being pulled out, it can be used for the subsequent lifting of the ton bag. After the movable hook 9 is separated from the hanging piece 14, the guide rod 12 can be released. After being released, the long rod 8 will drive the movable hook 9 back to its initial position under the elastic force of the spring 11.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
