Description

Technical Field

[0001] This utility model relates to the field of container technology, specifically to a container with top lifting lugs. Background Technology

[0002] Container lifting lugs are specialized load-bearing components on containers used for lifting, stacking, and securing. They are typically located at the top corners or sides of the container to facilitate safe handling by cranes, gantry cranes, and other equipment. Lifting lugs usually refer to the corner fittings of a container, namely the eight cast steel structural components at the top and bottom of the container. They are used for lifting, stacking, and securing, bearing the locking force of the spreader, and ensuring the stability of the container during transportation and loading / unloading. Corner fittings are defined as mandatory load-bearing components of a container and must meet specified dimensional, strength, and durability requirements. Lifting lugs have multiple functions, such as enabling vertical lifting and displacement of containers using cranes, gantry cranes, and other equipment; locking together multiple layers of stacked containers to prevent slippage or overturning; and securing the container in conjunction with lashing equipment (such as twist locks and tie rods) during ship, rail, or truck transportation.

[0003] A search revealed problems with existing container lifting lugs. On standard containers, corner brackets are used as lifting lugs; workers insert specialized lifting tools into these brackets to lift the container. However, in existing technologies, these corner brackets are often welded to the container. Over long-term use, the lifting lugs may deform or even break under heavy loads, requiring workers to remove the damaged lugs. Since lugs welded to the container are difficult to remove, subsequent reinstallation requires welding, making the process cumbersome. Therefore, based on the above research and existing technologies, a container with top lifting lugs is proposed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a container with top lifting lugs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A container with top lifting lugs includes: a container body, wherein a plurality of mounting slots are provided at the corners of the top and bottom surfaces of the container body, a support slot is provided on one side of the mounting slot, a corner fitting for lifting is installed inside the mounting slot, a locking hole for connecting a lifting device is reserved on the top surface of the corner fitting, and a connecting hole is reserved on three sides of the corner fitting; and two container doors are rotatably connected to one side of the container body.

[0007] The mounting component is disposed on the top surface of the mounting slot and is used to mount the corner piece.

[0008] Furthermore, the mounting assembly includes several mounting posts, all of which are fixedly mounted on the top surface of the mounting groove. A support plate is slidably connected to the outer circular wall of each mounting post, and a connecting ring is slidably connected to the outer circular wall of each mounting post. A spring is sleeved on the outer circular wall of each mounting post. A second connecting hole is opened on the bottom surface of the corner piece, and the support plate is slidably connected to the second connecting hole. A high-strength bolt is fixedly mounted on the inner bottom surface of the corner piece. Two positioning holes are opened on the top surface of the support plate, and the inner circular wall of the positioning holes is movably sleeved with the outer circular wall of the high-strength bolt. A nut is threaded onto the outer circular wall of the high-strength bolt.

[0009] Furthermore, the bottom surface of the mounting groove is provided with a plurality of positioning grooves, and the bottom surface of the corner piece is fixedly installed with a plurality of positioning posts, the outer circular wall surface of the positioning posts being movably connected to the inner circular wall surface of the positioning groove.

[0010] Furthermore, a magnet is magnetically attached to one side of the corner piece, a rope is fixedly attached to one end of the magnet, a limiting post is fixedly attached to the bottom surface of the support groove, an mounting block is fixedly attached to the top surface of the limiting post, a connecting plate is slidably connected to the outer circular wall of the limiting post, the lower end of the rope is fixedly connected to the top surface of the connecting plate, and a pressure sensor is fixedly attached to the bottom surface of the mounting block.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In one typical implementation of this application, please refer to Figures 1-5 A container with top lifting lugs includes a container body 1. Several mounting slots 3 are provided at the corners of the top and bottom surfaces of the container body 1. A support slot 8 is provided on one side of the inside of the mounting slot 3. An angle bracket 4 for lifting is installed inside the mounting slot 3. A locking hole 6 for connecting a lifting device is reserved on the top surface of the angle bracket 4. A connecting hole 5 is reserved on three sides of the angle bracket 4, through which a hand can be inserted into the inside of the angle bracket 4 for convenient subsequent installation. Two doors 2 are rotatably connected to one side of the container body 1 via hinges. Goods can be placed inside the container body 1 by rotating the doors 2. The mounting assembly is set on the top surface of the mounting slot 3 for mounting the angle bracket 4.

[0023] The mounting assembly includes several mounting posts 15, all of which are fixedly mounted on the top surface of the mounting groove 3. A support plate 14 is slidably connected to the outer circular wall of the mounting post 15, and a connecting ring 16 is slidably connected to the outer circular wall of the mounting post 15. A spring 17 is sleeved on the outer circular wall of the mounting post 15, with one end of the spring 17 fixedly connected to one end of the mounting post 15 and the other end of the spring 17 fixedly connected to the top surface of the connecting ring 16. A second connecting hole 13 is opened on the bottom surface of the corner piece 4, and the support plate 14 is slidably connected to the second connecting hole 13. A high-strength bolt 18 is fixedly installed on the inner bottom surface of the corner piece 4. Two positioning holes 19 are opened on the top surface of the support plate 14, and the inner circular wall of the positioning hole 19 is movably sleeved with the outer circular wall of the high-strength bolt 18. A nut is threadedly connected to the outer circular wall of the high-strength bolt 18.

[0024] The process involves placing the corner piece 4 on the mounting groove 3, allowing the support plate 14 to enter the interior of the corner piece 4. By moving the support plate 14 upward, the spring 17 is compressed. The worker then rotates the support plate 14 ninety degrees and releases it. The force of the spring 17 causes the support plate 14 to move downward, allowing the high-strength bolt 18 to enter the positioning hole 19 on the support plate 14. The high-strength bolt 18 is then locked with a nut, thus installing the corner piece 4 on the mounting groove 3. The corner piece 4 is easy to disassemble if damaged.

[0025] Preferably, using the corner bracket 4, the operator places the corner bracket 4 inside the mounting slot 3 on the container body 1, causing the support plate 14 on the mounting post 15 to enter the connecting hole 13 on the corner bracket 4. The operator moves the support plate 14 upward, causing the connecting ring 16 to move upward along the mounting post 15, while simultaneously compressing the spring 17. The operator moves the support plate 14 to a position higher than the high-strength bolts 18. The operator rotates the support plate 14 ninety degrees so that the support plate 14 is placed horizontally on the two high-strength bolts 18. The operator releases the support plate 14, and the force of the spring 17 causes the connecting ring 16 to move the support plate 14 downward along the mounting post 15. The support plate 14 moves downward, allowing the high-strength bolt 18 to enter the positioning hole 19 on the support plate 14. The worker places the nut on the high-strength bolt 18 and rotates the nut to lock the high-strength bolt 18, thereby locking the position of the corner piece 4 and achieving the installation effect of the corner piece 4. After long-term use, the corner piece 4 may deform. At this time, the worker rotates the nut to remove the nut from the high-strength bolt 18 and resets the support plate 14 to remove the damaged corner piece 4. This makes it convenient to install the corner piece 4 and also allows for quick disassembly. Compared with the existing technology of welding the corner piece 4 to the container body 1, it is more convenient and faster, and makes it easier for workers to use the corner piece 4 to lift the container body 1.

[0026] The bottom surface of the mounting groove 3 is provided with several positioning grooves 12, and the bottom surface of the corner piece 4 is fixedly installed with several positioning posts 11. The outer circular wall surface of the positioning post 11 is movably connected with the inner circular wall surface of the positioning groove 12. The corner piece 4 can be positioned by the cooperation of the positioning post 11 and the positioning groove 12.

[0027] Preferably, by using the corner piece 4, the operator places the corner piece 4 into the mounting groove 3 so that the positioning post 11 on the bottom of the corner piece 4 enters the positioning groove 12 on the mounting groove 3, thereby positioning the corner piece 4 and improving the installation accuracy of the corner piece 4.

[0028] A magnet 20 is magnetically attached to one side of the corner piece 4. A rope 22 is fixedly attached to one end of the magnet 20. A limiting post 25 is fixedly attached to the bottom surface of the support groove 8. An mounting block 23 is fixedly attached to the top surface of the limiting post 25. A connecting plate 10 is slidably connected to the outer circular wall of the limiting post 25. The lower end of the rope 22 is fixedly connected to the top surface of the connecting plate 10. A pressure sensor 24 is fixedly attached to the bottom surface of the mounting block 23.

[0029] When the corner piece 4 shakes and shifts, the corner piece 4 drives the rope 22 to move upward through the magnet 20. The upward movement of the rope 22 causes the connecting plate 10 to move upward. When the connecting plate 10 moves upward and comes into contact with the pressure sensor 24, the pressure sensor 24 will transmit a signal to the online platform to remind the staff.

[0030] Preferably, when the corner piece 4 is displaced due to excessive load, the corner piece 4 moves the rope 22 via the magnet 20. The rope 22 moves upward, causing the connecting plate 10 to move upward along the limiting post 25. When the connecting plate 10 moves upward and contacts the pressure sensor 24 on the bottom surface of the mounting block 23, the pressure sensor 24 senses the pressure. At this time, the pressure sensor 24 transmits the signal to the online platform, alerting the back-end staff to handle the damaged corner piece 4 in a timely manner.

[0031] The support groove 8 is connected to the support wheel 21 via a rotating shaft. Two limiting rings 9 are fixedly sleeved on the outer circular wall of the support wheel 21. The rope 22 can be guided by the cooperation of the limiting post 25 and the limiting rings 9.

[0032] Preferably, the support wheel 21 can guide the rope 22, which changes the direction of movement of the rope 22 from horizontal to vertical, thus changing the direction of the rope 22. The two limiting rings 9 on the support wheel 21 can restrict the rope 22, thereby achieving the effect of restricting the rope 22.

[0033] A rubber plate 7 is fixedly installed on the top surface of the corner piece 4, which can increase the friction between the two corner pieces 4.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
