Description

Technical Field

[0001] This utility model belongs to the field of logistics and transportation, specifically a container unloading device. Background Technology

[0002] Container unloading equipment is mainly used for the automated or semi-automated unloading of container cargo. Through components such as robotic arms, it realizes the transfer of containers by lifting tools. Its core function is to replace manual handling with mechanical structures and realize cargo handling by using the lifting and movement of equipment. It is an indispensable key equipment in modern logistics and other scenarios.

[0003] Existing container unloading equipment involves aligning the spreader with the four corner locks on the top of the container, ensuring vertical alignment of the spreader and container and that all four locks are fully engaged, then lifting the spreader at a uniform speed to ensure slow and smooth movement and avoid sudden stops that could cause the container to sway.

[0004] Existing unloading devices are difficult to dynamically adjust and cannot flexibly match the spacing of different container insertion holes. They require frequent manual operation. During the disassembly process, each loading and unloading requires individual adjustment or disassembly of connecting parts, which leads to increased time and low efficiency when disassembling containers.

[0005] Therefore, this utility model provides a container unloading device. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A container unloading device according to this utility model includes a robotic arm; multiple chains are installed at the end of the robotic arm; hooks are fixedly connected to the bottom of the chains; a lifting ring is fastened to the end of the hook; a threaded rod connects between two lifting rings; a shackle is slidably connected to the middle of the threaded rod; a shackle ring is fixedly connected to the side wall of the shackle; a nut is threadedly connected to the middle of the threaded rod; two nuts are arranged on both sides of the shackle; by setting the shackle and the shackle ring on a threaded rod, the distance between the two pairs of shackles and shackle rings can be adjusted by adjusting the nuts. At this time, when the shackles and shackle rings are loading and unloading the container, the distance between the two shackle rings can remain fixed, eliminating the need to pull out the shackle rings individually each time. This design reduces the disassembly time between the shackle rings and the container.

[0008] Preferably, multiple limiting seats are slidably connected to the middle of the threaded rod; a pull rod is fixedly connected to the side wall of each limiting seat. By providing multiple pull rods at the threaded rod, the unloading ring and the container can be quickly disassembled, improving the unloading efficiency of the entire equipment.

[0009] Preferably, the pull rod is rotatably connected to multiple support rings in the middle; multiple elastic fabrics are connected between the support rings that are close to each other. The linkage structure between the pull rod and the support rings achieves uniform force distribution on the cargo, and the elastic fabrics form a flexible buffer layer between the support rings to prevent collisions. Combined with the quick disassembly and detachment of the shackles and detachment rings, the stability and flexibility of the loading and unloading process are improved.

[0010] Preferably, a protective sleeve is fixedly attached to the middle of the chain; multiple protective sleeves are provided on the chain. By fixing multiple protective sleeves to the middle of the chain, the contact points between the chain and the shackles and release rings can be protected, reducing wear and tear, allowing the chain, shackles, and release rings to last longer, and making unloading more stable.

[0011] Preferably, multiple protective sleeves that are close to each other are connected by rubber rings; the rubber rings are wrapped around the middle of the chain. The connection of multiple rubber rings through protective sleeves makes the container more stable when it is lifted or disassembled. The protective sleeves wrapping around the middle of the chain can protect the chain, reduce chain wear, and extend its service life.

[0012] Preferably, a magnet is fixedly attached to the center of the protective sleeve; multiple magnets are provided on the protective sleeve. By fixing multiple magnets to the center of the protective sleeve, the adsorption and fixation effect on the goods can be enhanced, reducing the risk of goods shaking and slipping during unloading, and improving the stability and safety of unloading.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The container unloading device described in this utility model sets the shackles and unloading rings on a threaded rod. The distance between the two pairs of shackles and unloading rings can be adjusted by adjusting the nut. At this time, when the shackles and unloading rings are loading and unloading the container, the distance between the two unloading rings can be kept fixed, and it is not necessary to pull out the unloading rings individually each time. This setting reduces the disassembly time between the unloading rings and the container.

[0015] 2. The container unloading device described in this utility model uses multiple protective sleeves fixed to the middle of the chain to protect the chain and the contact points of the shackles and unloading rings, reducing wear and tear, making the chain, shackles and unloading rings last longer, and making unloading more stable.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1As shown in the embodiment of this utility model, a container unloading device includes a robotic arm 7; multiple chains 16 are installed at the end of the robotic arm 7; hooks 13 are fixedly connected to the bottom of the chains 16; lifting rings 12 are fastened to the end of the hooks 13; a threaded rod 1 is connected between two lifting rings 12; a shackle 14 is slidably connected to the middle of the threaded rod 1; unloading rings 15 are fixedly connected to the side wall of the shackle 14; a nut 11 is threadedly connected to the middle of the threaded rod 1; two nuts 11 are arranged on both sides of the shackle 14; during operation, the robotic arm 7 is first installed in the carriage or on a fixed workbench, then the robotic arm 7 is moved to the side of the container to be loaded or unloaded, and then the end of the robotic arm 7 is controlled to descend, so that the unloading rings 15 are close to the insertion hole of the container. Then, by controlling the nuts 11 to rotate on the threaded rod 1, the position of the shackles 14 and unloading rings 15 on the threaded rod 1 can be adjusted so that the position of the two unloading rings 15 is aligned with the insertion hole of the container. Correspondingly, the unloading ring 15 can then be inserted into the container socket to connect the unloading ring 15 to the container. Then, the lifting of the robotic arm 7 is controlled. At this time, the pulling force can be transmitted to the threaded rod 1 through the chain 16, hook 13 and ring 12 to lift the container. Then, the position of the entire robotic arm 7 is moved to realize the container handling. After the robotic arm 7 moves to the corresponding position, the lowering of the end of the robotic arm 7 is controlled to make the container contact the unloading platform. Then, the unloading ring 15 is pulled out from the container socket, and the container can be unloaded. By setting the shackle 14 and the unloading ring 15 on a threaded rod 1, the distance between the two pairs of shackles 14 and unloading rings 15 can be adjusted by adjusting the nut 11. At this time, when the shackles 14 and unloading rings 15 are loading and unloading the container, the distance between the two unloading rings 15 can be kept fixed, and it is not necessary to pull out the unloading ring 15 individually each time. This setting reduces the disassembly time between the unloading ring 15 and the container.

[0026] like Figures 1 to 2 As shown, multiple limiting seats 21 are slidably connected to the middle of the threaded rod 1; a pull rod 2 is fixedly connected to the side wall of the limiting seat 21; during operation, by adding multiple limiting seats 21 and pull rod 2 to the middle of the threaded rod 1, the pull rod 2 can be pulled during the process of pulling the unloading ring 15 out of the container's insertion hole. At this time, the pull rod 2 transmits the pulling force to the limiting seat 21 and the threaded rod 1, and the unloading ring 15 can be pulled out from the container's insertion hole, realizing the rapid disassembly between the unloading ring 15 and the container; by providing multiple pull rods 2 at the threaded rod 1, the rapid disassembly between the unloading ring 15 and the container can be realized, improving the unloading efficiency of the entire equipment for containers.

[0027] like Figure 3As shown, multiple support rings 31 are rotatably connected to the middle of the pull rod 2; multiple elastic fabrics 3 are connected between the support rings 31 that are close to each other. During operation, the multiple support rings 31 rotatably connected to the middle of the pull rod 2 enhance the overall adaptability and stability. The multiple elastic fabrics 3 are connected between the support rings 31. At the same time, the cooperation of the shackles 14 and the unloading rings 15 enables quick and reliable connection and disassembly, reducing the time for container unloading operations. The linkage structure between the pull rod 2 and the support rings 31 ensures that the force on the cargo is evenly distributed. The elastic fabrics 3 form a flexible buffer layer between the support rings 31 to prevent collisions. Combined with the quick disassembly of the shackles 14 and the unloading rings 15, the stability and flexibility of the loading and unloading process are improved.

[0028] like Figure 4 As shown, a protective sleeve 4 is fixedly attached to the middle of the chain 16; multiple protective sleeves 4 are provided on the chain 16. During operation, the chain 16 is connected by shackles 14 and unloading rings 15. The multiple protective sleeves 4 fixed to the chain 16 can protect the chain 16 and the container during unloading, reducing wear and collision. By fixing multiple protective sleeves 4 to the middle of the chain 16, the contact points between the chain 16 and the shackles 14 and unloading rings 15 can be protected, reducing wear and making the chain 16, shackles 14 and unloading rings 15 last longer and unloading more stably.

[0029] like Figure 5 As shown, rubber rings 5 ​​connect the multiple adjacent protective sleeves 4; the rubber rings 5 ​​wrap around the middle of the chain 16. During operation, the adjacent protective sleeves 4 are connected by the rubber rings 5, and the rubber rings 5 ​​wrap around the middle of the chain 16. The protective sleeves 4 can protect the chain 16 during disassembly or hoisting, improving the stability and durability of the unloading device; the multiple rubber rings 5 ​​connected by the protective sleeves 4 can make the container more stable when being hoisted or disassembled. The protective sleeves 4 wrap around the middle of the chain 16, which can protect the chain 16, reduce wear on the chain 16, and extend its service life.

[0030] like Figure 6 As shown, a magnet 6 is fixedly attached to the middle of the protective sleeve 4; multiple magnets 6 are provided on the protective sleeve 4. During operation, multiple magnets 6 on the protective sleeve 4 are attracted to the surface of the container, providing a stable connection. Subsequently, with the cooperation of components such as the threaded rod 1 and the pull rod 2, the container can be safely unloaded. The elastic cloth 3 can play a buffering and protective role. By fixing multiple magnets 6 in the middle of the protective sleeve 4, the attraction and fixation effect on the cargo can be enhanced, reducing the risk of cargo shaking and slipping during unloading, and improving the stability and safety of unloading.

[0031] The working principle is as follows: First, the robotic arm 7 is installed in the vehicle compartment or on a fixed workbench. Then, the robotic arm 7 is moved to the side of the container to be loaded or unloaded. Next, the end of the robotic arm 7 is lowered so that the unloading ring 15 is close to the insertion hole of the container. Then, the nut 11 is rotated on the threaded rod 1 to move its position. At this time, the positions of the shackle 14 and the unloading ring 15 on the threaded rod 1 can be adjusted so that the positions of the two unloading rings 15 correspond to the insertion holes of the container. Then, the unloading ring 15 can be inserted into the container insertion hole to achieve the connection between the unloading ring 15 and the container. Then, the lifting of the robotic arm 7 is controlled. At this time, the pulling force is transmitted to the threaded rod 1 through the chain 16, hook 13, and lifting ring 12, which can lift the container. Then, the position of the entire robotic arm 7 is moved to realize the container handling. After the robotic arm 7 moves to the corresponding position, the lowering of the end of the robotic arm 7 is controlled so that the container contacts the unloading platform. Then, the unloading ring 15 is pulled out from the container's insertion hole, and the container can be unloaded. By adding multiple limit seats 21 and pull rods 2 in the middle of the threaded rod 1, the unloading ring 15 can be pulled out from the container's insertion hole. During the process, by pulling the lever 2, the pulling force is transmitted to the limit seat 21 and the threaded rod 1, and the unloading ring 15 can be pulled out from the container's insertion hole, realizing the quick disassembly of the unloading ring 15 from the container; the middle of the lever 2 is rotatably connected to multiple support rings 31, which enhances the overall adaptability and stability. Multiple elastic cloths 3 are connected between the support rings 31. At the same time, the cooperation of the shackle 14 and the unloading ring 15 realizes quick and reliable connection and disassembly, reducing the time of container unloading operations; the chain 16 is connected to the shackle 14 and the unloading ring 15. Multiple protective sleeves 4, fixed to the chain 16, can protect the chain 16 and the container during unloading, reducing wear and collision. The protective sleeves 4, which are close to each other, are connected by rubber rings 5. The rubber rings 5 ​​wrap around the middle of the chain 16. The protective sleeves 4 can protect the chain 16 during disassembly or hoisting, improving the stability and durability of the unloading device.
