Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary loading and unloading, and specifically provides a goods loading and unloading auxiliary device for international trade. Background Art

[0002] International trade refers to the transaction of goods and services across national borders, generally composed of import trade and export trade, and can also be called import and export trade. In international trade, the loading and unloading equipment of goods plays a crucial role. As the core link of the logistics chain, the international trade goods loading and unloading equipment has a profound impact on the operation efficiency, cost control and sustainable development of global trade.

[0003] At present, the loading and unloading equipment for international trade goods mainly includes equipment such as cranes and forklifts, and containers are mostly used for transportation. However, the existing loading and unloading equipment in the prior art is difficult to load and unload heavy objects in containers, so manual labor is required when loading goods into containers. However, when encountering heavy objects, manual loading and unloading is extremely laborious and dangerous. Especially when the goods are stacked to a relatively high position, the difficulty of loading and unloading the goods increases sharply.

[0004] Combining the above problems, we will find that the existing goods loading and unloading equipment on the market is very difficult to avoid the above-mentioned problems simultaneously when in use. And even if it can be solved, it needs to be solved by cooperating with external tools, thus unable to achieve the desired effect. Therefore, we propose a goods loading and unloading auxiliary device for international trade. Summary of the Invention

[0015] Preferably, a rubber pad is fixedly installed on the surface of the arc-shaped convex block, and the surface of the rubber pad is in contact with the surface of the guide roller.

[0016] Preferably, the unlocking component is arranged in a cavity inside the support platform. The cavity is communicated with the groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. After stacking a part of the goods inside the container, the present invention squeezes and moves them to the side of the container, then places the goods on the conveyor belt, and drives the support platform to move upward through the hydraulic cylinder. The support platform pushes the bracket upward through the guide roller, so as to achieve the effect of lifting the goods and making the goods flush with the stacked goods. Then, the moving frame is pushed, so that the moving frame moves to the side of the goods inside the container, and when the moving frame moves in place, the braking and stopping assembly is automatically unlocked, so that the braking and stopping assembly no longer brakes the guide roller. Then, the goods are pushed, and the conveyor belt is slidably sleeved on the surface of the bracket, so that the conveyor belt rotates around the bracket when the goods are pushed, and the guide roller is used to prevent the conveyor belt from rubbing against the support platform, so that it is more labor-saving when unloading the goods, and thus the heavier goods can be easily stacked to a high place.

[0020] 2. The present invention supports the position of the cross plate through the unlocking assembly, and the cross plate supports the position of the arc-shaped convex block, so that the arc-shaped convex block tightly abuts against the guide roller, thereby preventing the guide roller from rotating. And through the anti-slip convex block contacting the guide roller, the guide roller plays a role in braking the conveyor belt, preventing the situation that the conveyor belt moves and the goods fall when the moving frame moves.

[0021] 3. When the moving frame is about to move in place, the top plate contacts the goods. Under the block of the goods, the top plate stops moving. Under the support of the top plate, the moving plate stops moving. The moving frame continues to move. When the moving frame moves in place, the cross plate separates from the inclined surface convex block, and the inclined surface convex block no longer supports the position of the cross plate, so as to achieve the effect of automatic unlocking and facilitate the unloading of the goods.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Please refer to Figures 1 - 8 , the present invention provides a technical solution: A cargo handling auxiliary device for international trade, including a base frame 1, a counterweight 2 is fixedly installed on the top of the base frame 1, a moving frame 3 is slidably connected to one side of the base frame 1, a first support assembly 4 is slidably connected inside the moving frame 3, and a lifting mechanism 5 is fixedly installed inside the moving frame 3. The lifting mechanism 5 is used in cooperation with the first support assembly 4;

[0033] The first support assembly 4 includes a bracket 41 slidably connected inside the moving frame 3, a conveyor belt 42 is slidably sleeved on the surface of the bracket 41, and a plurality of anti-slip bumps 43 are fixedly installed on the surface of the conveyor belt 42;

[0034] The lifting mechanism 5 includes a hydraulic cylinder 51 fixedly installed inside the moving frame 3. The telescopic end of the hydraulic cylinder 51 is fixedly connected with a support platform 52. The support platform 52 is slidably connected to the inner cavity of the moving frame 3. An arc-shaped groove 53 is formed on the surface of the support platform 52. A guide roller 54 is rotatably installed inside the arc-shaped groove 53. The surface of the guide roller 54 is attached to the surface of the conveyor belt 42. The guide roller 54 is used in cooperation with the anti-slip convex block 43. A braking component 55 is arranged inside the arc-shaped groove 53. The braking component 55 is used in cooperation with the guide roller 54. After stacking a part of the goods at the innermost side of the container, the extrusion is moved next to the container. Then the goods are placed on the conveyor belt 42, and the hydraulic cylinder 51 drives the support platform 52 to move upward. The support platform 52 pushes the support frame 41 upward through the guide roller 54, so as to achieve the effect of lifting the goods and making the goods flush with the stacked goods. Then the moving frame 3 is pushed to move the moving frame 3 to the side of the goods at the innermost side of the container. When the moving frame 3 is in place, the braking component 55 is automatically unlocked, so that the braking component 55 no longer brakes the guide roller 54. Then the goods are pushed, and the conveyor belt 42 is slidably sleeved on the surface of the support frame 41, so that the conveyor belt 42 rotates around the support frame 41 when the goods are pushed. And the guide roller 54 is used to prevent the conveyor belt 42 from rubbing against the support platform 52, so that it is more labor-saving when unloading the goods, and thus the heavier goods can be easily stacked to a higher place.

[0035] As a further limitation of the base frame 1 of the present invention, a slide rail 101 is fixedly installed on one side of the base frame 1. A slider 102 is fixedly installed at the bottom of the moving frame 3. The inner cavity of the slider 102 is slidably connected to the surface of the slide rail 101. By the inner cavity of the slider 102 being slidably connected to the surface of the slide rail 101, the moving frame 3 is more labor-saving when moving.

[0036] A first limiting block 44 is fixedly installed on the inner wall of the conveyor belt 42. A first limiting groove 45 is formed on the surface of the support frame 41. The inner cavity of the first limiting groove 45 is slidably connected to the surface of the first limiting block 44. By the inner cavity of the first limiting groove 45 being slidably connected to the surface of the first limiting block 44, the position of the conveyor belt 42 can be effectively stabilized, and the situation such as the deviation of the conveyor belt 42 affecting the position of the goods can be avoided.

[0037] A second support component 6 is fixedly installed on the surface of the base frame 1. The second support component 6 has the same structure as the first support component 4. By arranging the second support component 6 on the base frame 1, it is convenient to place the goods on the second support component 6, so as to transfer the goods to the first support component 4 through the second support component 6, so as to enter the goods from the outside of the container into the container.

[0038] A support block 46 is fixedly connected to the surface of the support 41. A support groove 47 is formed in the inner wall of the movable frame 3. The surface of the support block 46 is slidably connected to the inner cavity of the support groove 47. A positioning rod 48 is fixedly connected inside the support groove 47. One end of the positioning rod 48 penetrates through the support block 46 and is slidably connected to the support block 46. By sliding the surface of the support block 46 in the inner cavity of the support groove 47 and stabilizing the position of the support block 46 through the positioning rod 48, the position of the support 41 inside the movable frame 3 can be effectively stabilized, avoiding situations such as tilting and offset of the movable frame 3 that may cause the goods to fall.

[0039] The specific implementation of this embodiment is as follows: After stacking a part of the goods at the innermost side of the container, move the extrusion device to the side of the container and align the slide rail 101 with the container so that the movable frame 3 is located inside the container. Then place the goods on the second support assembly 6 and align the first support assembly 4 with the second support assembly 6, facilitating the transfer of the goods to the first support assembly 4. Then, drive the support platform 52 to move upward by the hydraulic cylinder 51. The support platform 52 pushes the support 41 upward through the guide rollers 54. Since the surface of the support block 46 is slidably connected to the inner cavity of the support groove 47 and the position of the support block 46 is stabilized by the positioning rod 48, the position of the support 41 can be made more stable, thereby achieving the effect of lifting the goods and making the goods level with the stacked goods. Then, push the movable frame 3. The movable frame 3 moves on the slide rail 101 through the slider 102, making it more labor-saving when the movable frame 3 moves. The anti-slip convex blocks 43 prevent the goods from slipping and falling off. When the movable frame 3 moves to the side of the innermost goods in the container, when the movable frame 3 reaches the designated position, the braking and stopping assembly 55 is automatically unlocked, so that the braking and stopping assembly 55 no longer brakes the guide rollers 54. Then, push the goods. The conveyor belt 42 is slidably sleeved on the surface of the support 41, and the surface of the first limit block 44 is slidably connected to the inner cavity of the first limit groove 45 to stabilize the position of the conveyor belt 42, enabling the conveyor belt 42 to rotate around the support 41 when the goods are pushed. The guide rollers 54 prevent the conveyor belt 42 from rubbing against the support platform 52, making it more labor-saving when unloading the goods, thus easily stacking heavier goods to a higher position. When unloading heavy goods at a higher position, the first support assembly 4 can also be lifted to a position level with the goods, placing the goods on the first support assembly 4 and then lowering the first support assembly 4. Subsequently, move the movable frame 3 outward from the container to facilitate the removal of the goods.

[0040] Embodiment 2: Please refer to Figures 1 - 8 , the present invention provides a technical solution: A goods loading and unloading auxiliary device for international trade. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0041] As a further limitation of the lifting mechanism 5 of the present invention, a connection block 5201 is fixedly installed on the surface of the support platform 52, and a connection frame 5202 is fixedly installed on the surface of the moving frame 3. The surface of the connection block 5201 is slidably connected to the inner cavity of the connection frame 5202; by slidingly connecting the inner cavity of the connection block 5201 to the surface of the connection frame 5202, the position of the support platform 52 can be effectively stabilized, avoiding the situation that the support platform 52 is tilted, offset, etc., which may cause damage to the hydraulic cylinder 51, and at the same time avoiding affecting the support effect of the support platform 52.

[0042] The braking component 55 includes a groove 5501 opened inside the arc-shaped groove 53. An arc-shaped convex block 5502 is slidably connected inside the groove 5501. The arc-shaped convex block 5502 is used in cooperation with the guide roller 54. The bottom of the arc-shaped convex block 5502 is fixedly connected to a cross plate 5503. An unlocking component 56 is arranged inside the support platform 52. The unlocking component 56 is used in cooperation with the cross plate 5503; by the unlocking component 56 to support the position of the cross plate 5503, and the cross plate 5503 to support the position of the arc-shaped convex block 5502, so that the arc-shaped convex block 5502 tightly abuts against the guide roller 54, thus avoiding the situation that the guide roller 54 rotates. And by the anti-slip convex block 43 contacting the guide roller 54, the guide roller 54 plays a role in braking the conveyor belt 42, avoiding the situation that the conveyor belt 42 moves when the moving frame 3 moves, resulting in the goods falling.

[0043] A rubber pad 5504 is fixedly installed on the surface of the arc-shaped convex block 5502. The surface of the rubber pad 5504 is attached to the surface of the guide roller 54; by installing the rubber pad 5504 on the surface of the arc-shaped convex block 5502 and making the rubber pad 5504 abut against the guide roller 54, the friction between the arc-shaped convex block 5502 and the guide roller 54 can be effectively increased, thus effectively improving the braking effect of the guide roller 54.

[0044] The specific implementation manner of this embodiment is as follows: during the movement of the moving frame 3, the unlocking component 56 supports the position of the cross plate 5503, and the cross plate 5503 supports the position of the arc-shaped convex block 5502, so that the arc-shaped convex block 5502 tightly abuts against the guide roller 54, and the friction between the arc-shaped convex block 5502 and the guide roller 54 is increased by the rubber pad 5504, so that the braking component 55 plays a role in braking the guide roller 54, avoiding the situation that the guide roller 54 rotates. And by the anti-slip convex block 43 contacting the guide roller 54, the guide roller 54 plays a role in braking the conveyor belt 42, avoiding the situation that the conveyor belt 42 moves when the moving frame 3 moves, resulting in the goods falling. Moreover, when the moving frame 3 moves in place, the unlocking component 56 no longer supports the position of the cross plate 5503, so that the cross plate 5503 and the arc-shaped convex block 5502 naturally fall inside the groove 5501, so that the arc-shaped convex block 5502 and the rubber pad 5504 are separated from the guide roller 54, so that the braking component 55 no longer plays a role in braking the guide roller 54, in order to push the goods off the first support component 4.

[0045] Embodiment 3: Please refer to Figures 1 - 8 , the present invention provides a technical solution: a cargo loading and unloading auxiliary device for international trade, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0046] As a further limitation of the unlocking component 56 of the present invention, a cavity 5601 is provided inside the support platform 52 of the unlocking component 56. The cavity 5601 communicates with the groove 5501. One end of the cross plate 5503 extends into the cavity 5601 and is slidably connected to the inner cavity of the cavity 5601. A moving plate 5602 is slidably connected inside the cavity 5601. A beveled convex block 5603 is fixedly installed on the surface of the moving plate 5602. The beveled convex block 5603 is used in cooperation with the cross plate 5503. One end of the moving plate 5602 penetrates through the support platform 52 and is slidably connected to the support platform 52. One end of the moving plate 5602 is fixedly connected to a top plate 5604. A spring 5607 is fixedly installed inside the cavity 5601. One end of the spring 5607 is fixedly connected to the other end of the moving plate 5602; when the moving frame 3 is about to move in place, the top plate 5604 contacts the goods. Under the blockage of the goods, the top plate 5604 stops moving. Under the support of the top plate 5604, the moving plate 5602 stops moving. The moving frame 3 continues to move. When the moving frame 3 moves in place, the cross plate 5503 separates from the beveled convex block 5603, and the beveled convex block 5603 no longer supports the position of the cross plate 5503, so as to achieve the function of automatic unlocking and facilitate the unloading of goods.

[0047] A second limit block 5605 is fixedly installed at the bottom of the moving plate 5602. A second limit groove 5606 is provided inside the cavity 5601. The inner cavity of the second limit groove 5606 is slidably connected to the surface of the second limit block 5605; by making the surface of the second limit block 5605 slidably connected to the inner cavity of the second limit groove 5606, the position of the moving plate 5602 is stabilized to prevent the moving plate 5602 from shifting or the like, which may affect the supporting position of the beveled convex block 5603.

[0048] The specific implementation manner of this embodiment is as follows: When the moving frame 3 is about to move into place, the top plate 5604 contacts the goods. Under the obstruction of the goods, the top plate 5604 stops moving. Under the support of the top plate 5604, the moving plate 5602 stops moving. The moving frame 3 continues to move. When the moving frame 3 moves into place, the moving plate 5602 slides inside the cavity 5601 and is slidably connected to the inner cavity of the second limiting groove 5606 through the surface of the second limiting block 5605 to stabilize the position of the moving plate 5602 and prevent the moving plate 5602 from shifting or the like, so that the cross plate 5503 slides on the surface of the inclined convex block 5603, and then the cross plate 5503 is separated from the inclined convex block 5603. The inclined convex block 5603 no longer supports the position of the cross plate 5503, so that the cross plate 5503 and the arc convex block 5502 move downward and no longer brake the guide roller 54, achieving the function of automatic unlocking and facilitating the unloading of goods.
