Description

Technical Field

[0001] This invention relates to the field of port safety technology, specifically to a safety protection device for containers and its usage. Background Technology

[0002] In the daily operation of port terminals, the loading, unloading, transportation and storage of containers is a complex and critical process. Due to the special characteristics of the port environment, such as space constraints, busy operations and diverse equipment, the safety management of containers faces many challenges. In the port terminal environment, operations are mostly carried out by a combination of automated mechanical equipment and manual labor. The following problems still exist in the current process of lifting and stacking containers: Severe weather conditions such as typhoons, storms, and blizzards frequently occur during operations, causing containers to tilt under stress, especially shorter containers. Without timely safety measures, this can lead to serious accidents, damaging cargo and severely impacting the port's economy. Especially in severe weather, it is difficult to rely solely on manpower to achieve 24 / 7 safety monitoring of all containers in a large port area. Furthermore, due to the uneven weight distribution of containers and their contents, they are not strictly at the geometric center of the container. Therefore, the container as a whole is prone to slight tilting during lifting, resulting in uneven stacking and increasing the risk of accidents.

[0003] In view of this, we propose a safety protection device for containers and its application to solve the existing problems. Summary of the Invention

[0004] The purpose of this invention is to provide a safety protection device for containers and its usage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safety protection device for a container and its usage, comprising a mobile security vehicle, an active locking device, a passive locking device, an oblique tie rod, and a vertical tie rod. The mobile security vehicle has universal drive wheels at each of its four bottom corners, a snap-fit ​​plate on one side of its upper part, and symmetrically distributed slide rails on the other side of its upper part. The bottom of the mobile security vehicle has a first servo drive component. The drive end of the first servo drive component is rotatably provided with a lead screw that penetrates the bottom of the mobile security vehicle. Multiple sets of clamping plates are slidably arranged between the lead screw and the slide rails. A position adjustment device is slidably arranged on the upper side of the middle part of the mobile security vehicle. A telescopic mechanism is fixedly arranged on the upper side of the position adjustment device, and a clamping device is installed at the top of the telescopic mechanism. A second radar detection device is installed on the top of the slide frame.

[0006] Preferably, the position adjustment device includes a lateral position adjustment mechanism and a longitudinal position adjustment mechanism. The lateral position adjustment mechanism is installed between the lateral side plates of the mobile security vehicle, and the longitudinal position adjustment mechanism is installed on the upper side of the lateral position adjustment mechanism. The bottom end of the telescopic mechanism is fixedly connected to the upper side of the longitudinal position adjustment mechanism.

[0007] Preferably, the clamping device includes a second servo drive assembly, a fixed clamping component, a movable clamping component, a magnetic gripper, and an angle adjustment mechanism. The angle adjustment mechanism is fixedly disposed at the top of the telescopic mechanism. The second servo drive assembly and the fixed clamping component are rotatably connected to the angle adjustment mechanism. The movable clamping component and the magnetic gripper are slidably disposed at the drive end of the second servo drive assembly.

[0008] Preferably, the active locking device includes an active locking frame, one end of which is fixedly provided with an active locking mechanism, and the other end is internally provided with four first positioning posts arranged in a rectangular pattern. A set of locking screws is rotatably arranged through and between the two ends of the active locking frame. One end of the set of locking screws extends out of the end of the active locking frame, and the other end of the locking screws is rotatably connected to the power output end of the active locking mechanism. The outer end of the active locking mechanism is fixedly equipped with a first radar detection device.

[0009] Preferably, the passive locking device includes a passive locking frame, one end of which has a set of connecting rods, and the inner side of one end of the passive locking frame has four second positioning posts arranged in a rectangular pattern, and the other end of the passive locking frame has connecting posts; The connecting rod has a threaded hole along its length, and in the assembled state, the threaded hole is threadedly connected to one end of the locking screw.

[0010] Preferably, both ends of the diagonal tie rod have a first sleeve, which, when assembled, is fitted onto the outer periphery of the connecting post.

[0011] Preferably, both ends of the vertical tie rod have a second sleeve, and the middle of the vertical tie rod has a strong magnetic sleeve. In the combined state, the second sleeve is fastened to the outer periphery of the connecting column, and the strong magnetic sleeve is fastened to the end of the connecting column.

[0012] To achieve the above objectives, a method of using a safety protection device for a container includes the following steps: Step 1: Before reinforcing the container, the active locking device and the passive locking device are locked between multiple sets of clamps, and the diagonal tie rod and the vertical tie rod are vertically locked onto the clamping plate; Step 2: During the inspection process, the second radar detection device of the mobile security vehicle detects the deviation of the container in real time. If the deviation exceeds the safe range, the second radar detection device issues an early warning and moves the mobile security vehicle to the side of the container to reinforce it. Step 3: After the position adjustment device drives the telescopic mechanism and the clamping device to move, it extends upward to clamp multiple active locking devices. After moving upward, the locking devices are inserted into the diagonal positions on one side of the four containers to lock them. Step 4: After the position adjustment device drives the telescopic mechanism and the clamping device to move, it extends upward to clamp multiple passive locking devices. After moving upward, the passive locking devices are inserted into the diagonal positions on one side of the four containers for locking. Step 5: After the position adjustment device drives the telescopic mechanism and the clamping device to move, it extends upward to clamp multiple diagonal tie rods and fastens them diagonally around the outer periphery of the two connecting columns along the container. The vertical tie rods are fastened to the ends of the three connecting columns along the shorter inner diagonal of the rhombus formed after the diagonal tie rods are fastened. Step 6: When reinforcing the container, in the combined state, multiple first radar detection devices detect and position each other, so that the active locking device begins to screw into the passive locking device for threaded connection and locking.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention uses a mobile security vehicle with radar detection function to detect whether the container is tilting or protruding. Then, the active locking device and the passive locking device work together to lock the container. At the same time, the diagonal tie rod and the vertical tie rod work together with the end of the passive locking device to fix and lock multiple containers together, thereby achieving the purpose of stabilizing and protecting the containers. This overcomes the safety disadvantages caused by uneven container stacking. This technical solution can save a lot of manpower, reduce safety risks, and achieve the effect of intelligent and automated container security protection. Attached Figure Description

[0022] like Figures 1 to 8As shown, the present invention proposes a container safety protection device and its usage, including a mobile security vehicle 1, an active locking device 2, a passive locking device 3, an oblique tie rod 4, and a vertical tie rod 5. The mobile security vehicle 1 has omnidirectional drive wheels 6 at each of its four bottom corners, a locking plate 7 on one side of its upper part, and symmetrically distributed sliding frames 8 on the other side of its upper part. Further, a second radar detection device 81 is installed on the top of the sliding frames 8. In use, according to the detection status and adjustment command of the second radar detection device 81, the omnidirectional drive wheels 6 work to move the mobile security vehicle 1 to the side of the container requiring reinforcement and protection. The bottom of the mobile security vehicle 1 has a first servo drive component 9, and the drive end of the first servo drive component 9 is rotatably equipped with a lead screw 10 that penetrates the bottom of the mobile security vehicle 1. Multiple sets of clamping plates 11 are slidably arranged between the sliding frame 8 and the chute frame 8. During use, the first servo drive unit 9 drives the lead screw 10 to synchronously raise and slide the multiple sets of clamping plates 11 to supply the active locking device 2 and the passive locking device 3 to the clamping device 14. A position adjustment device 12 is slidably arranged on the upper side of the middle of the mobile security vehicle 1. A telescopic mechanism 13 is fixedly arranged on the upper side of the position adjustment device 12, and the clamping device 14 is installed at the top of the telescopic mechanism 13. After the position adjustment device 12 on the mobile security vehicle 1 adjusts the position of the telescopic mechanism 13, the clamping device 14... The active locking device 2 is inserted on one side of the container, and the passive locking device 3 is inserted on the other side of the container and is threadedly connected and locked to the active locking device 2. The diagonal tie rod 4 and the vertical tie rod 5 are both sleeved on the end of the passive locking device 3 to tighten and lock the passive locking device 3, thereby locking the four containers at opposite corners into a whole. This technical solution can save a lot of manpower, reduce safety risks, and achieve the effect of intelligent and automated safety protection of containers.

[0023] Furthermore, the position adjustment device 12 includes a lateral position adjustment mechanism 1201 and a longitudinal position adjustment mechanism 1202. The lateral position adjustment mechanism 1201 is installed between the lateral side plates of the mobile security vehicle 1, and the longitudinal position adjustment mechanism 1202 is installed on the upper side of the lateral position adjustment mechanism 1201. The bottom end of the telescopic mechanism 13 is fixedly connected to the upper side of the longitudinal position adjustment mechanism 1202. In use, the lateral position adjustment mechanism 1201 drives the longitudinal position adjustment mechanism 1202 to slide back and forth in the lateral direction, while the longitudinal position adjustment mechanism 1202 slides back and forth in the longitudinal direction, thereby adjusting the position of the telescopic mechanism 13. This allows the telescopic mechanism 13 to drive the clamping device 14 to clamp the devices between different sets of clamping devices 14 and to clamp the different oblique pull rods 4 and vertical pull rods 5 of the snap-fit ​​plate 7.

[0024] Furthermore, the clamping device 14 includes a second servo drive assembly 1401, a fixed clamping member 1402, a movable clamping member 1403, a magnetic gripper 1404, and an angle adjustment mechanism 1405. The angle adjustment mechanism 1405 is fixedly mounted on the top of the telescopic mechanism 13. The second servo drive assembly 1401 and the fixed clamping member 1402 are rotatably connected to the angle adjustment mechanism 1405. The movable clamping member 1403 and the magnetic gripper 1404 are slidably mounted on the drive end of the second servo drive assembly 1401. In use, the second servo drive assembly 1401 drives the movable clamping member 1403 to slide and clamp the clamped device 14 between itself and the fixed clamping member 1402, and then moves it to the locking position. At this time, the angle adjustment mechanism 1405 rotates to finely adjust the angle of the locking device, thereby realizing automated and precise assembly and locking.

[0025] Furthermore, the active locking device 2 includes an active locking frame 21. An active locking mechanism 22 is fixedly installed at one end of the active locking frame 21, and four rectangularly distributed first positioning posts 23 are fixedly installed inside the other end. In use, the four rectangularly distributed first positioning posts 23 are inserted into the holes at the diagonal corners of the four containers. A set of locking screws 24 is rotatably installed between the two ends of the active locking frame 21. One end of the set of locking screws 24 extends out of the end of the active locking frame 21, and the other end of the locking screws 24 is rotatably connected to the power output end of the active locking mechanism 22. In use, the active locking mechanism 22 drives the set of locking screws 24 to rotate in the active locking frame 21 to achieve different degrees of connection and locking. The outer end of the active locking mechanism 22 is fixedly provided with a first radar detection device 15. In use, multiple first radar detection devices 15 detect and position each other, analyze the degree of deviation of one of the first radar detection devices 15, and then the active locking device 2 starts to screw into the passive locking device 3 for threaded connection and locking, so that the deviated first radar detection device 15 and other first radar detection devices 15 are restored to the same plane position as much as possible.

[0026] Furthermore, the passive locking device 3 includes a passive locking frame 31. One end of the passive locking frame 31 has a set of connecting rods 32. Further, threaded holes 16 are provided along the connecting rods 32. In the combined state, the threaded holes 16 are threadedly connected to one end of the locking screw 24. The inner side of one end of the passive locking frame 31 has four rectangularly distributed second positioning posts 33. In use, the four rectangularly distributed second positioning posts 33 are inserted into the holes at the four diagonal corners of the container to achieve positioning. The other end of the passive locking frame 31 has a connecting post 34. In use, one connecting post 34 is connected to another connecting post 34 through the diagonal tie rod 4 and the vertical tie rod 5 to form an overall locking structure and achieve the effect of locking the overall structure.

[0027] Furthermore, both ends of the diagonal tie rod 4 have a first sleeve 41. In the combined state, the diagonal tie rod 4 is placed diagonally along the container, and the first sleeve 41 at both ends of the diagonal tie rod 4 is fastened to the outer periphery of the connecting column 34.

[0028] Furthermore, both ends of the vertical tie rod 5 have a second sleeve 51, and the middle of the vertical tie rod 5 has a strong magnetic suction sleeve 52. When the diagonal tie rod 4 is connected, in the combined state, the second sleeves 51 at both ends of the vertical tie rod 5 are fastened to the outer periphery of the two vertically distributed connecting columns 34, and the strong magnetic suction sleeve 52 is fastened to the end of the connecting column 34 in the middle. Through the magnetic attraction, the vertical tie rod 5 is prevented from easily falling off, thus enhancing the stability of the structure.

[0029] To achieve the above objectives, a method of using a safety protection device for a container includes the following steps: Step 1: Before securing the container, the active locking device 2 and the passive locking device 3 are placed between multiple sets of clamping plates 11, and the diagonal tie rod 4 and the vertical tie rod 5 are vertically placed on the clamping plate 7; thus realizing the storage and supply of multiple locking devices. Step 2: During the inspection process, the second radar detection device 81 of the mobile security vehicle 1 detects the degree of deviation of the container in real time. The second radar detection device 81 inspects whether multiple containers are on the same plane in real time. If there is a deviation from the safe range, the second radar detection device 81 issues an early warning and moves the mobile security vehicle 1 to the side of the container to reinforce the container. Step 3: After the position adjustment device 12 drives the telescopic mechanism 13 and the clamping device 14 to move, they extend upward to clamp multiple active locking devices 2. After moving upward, the locking devices are inserted into the diagonal positions on one side of the four containers to lock them. Step 4: After the position adjustment device 12 moves the telescopic mechanism 13 and the clamping device 14, it extends upward to clamp multiple passive locking devices 3. After moving upward, the passive locking devices 3 are inserted into the diagonal positions on one side of the four containers for locking. Step 5: After the position adjustment device 12 moves the telescopic mechanism 13 and the clamping device 14, it extends upward to clamp multiple diagonal tie rods 4 and fastens them diagonally around the two connecting posts 34. The vertical tie rods 5 fasten along the shorter inner diagonal of the rhombus formed after the diagonal tie rods 4 are fastened to the ends of the three connecting posts 34. Step 6: When the container is being reinforced, multiple first radar detection devices 15 in the combined state detect and position each other, so that the active locking device 2 begins to screw into the passive locking device 3 for threaded connection and locking.

[0030] This invention utilizes a mobile security vehicle 1 equipped with radar detection to detect whether containers are tilting or protruding. Then, an active locking device 2 and a passive locking device 3 work together to lock the containers. Simultaneously, diagonal tie rods 4 and vertical tie rods 5 engage with the ends of the passive locking device 3, achieving a fixed connection and locking between multiple containers. This stabilizes and protects the containers, overcoming the safety risks caused by uneven container stacking. This technical solution saves significant manpower, reduces safety risks, and achieves intelligent and automated container security protection.

[0031] The above specific embodiments are merely several preferred embodiments of the present invention.
