Description

Technical Field

[0001] This invention relates to the field of container stacking safety protection technology, and in particular to an earthquake-resistant reinforcement device for container stacking yards. Background Technology

[0002] As a core hub in the container shipping chain, container yards play a crucial role in the centralized storage, temporary transshipment, and scheduling of containers. To maximize the use of space resources, container yards typically employ multi-layer stacking to store large numbers of containers. These stacked containers are numerous and have a large total mass, forming a dense stacking structure.

[0003] In existing technologies, container securing relies on a lock handle that rotates the lock head within the container corner fitting. Positioning is achieved through a locking mechanism between the bottom of the lock head and the inner wall of the corner fitting. However, because the lock handle is directly exposed to the external environment without any limiting or securing mechanisms, it is highly susceptible to accidental rotation when subjected to external factors such as wind or collisions with equipment. This can cause the lock head to disengage from the main hole in the corner fitting, creating a gap and resulting in loosening at the connection between the lock head and the container corner fitting. This loosening directly compromises the vertical stability of the connection between the container and the steel frame, and in severe cases, can lead to container shifting, tilting, or even tipping over, posing a significant safety hazard to operations in the storage yard.

[0004] Accordingly, this application proposes a seismic reinforcement device for container storage yards. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seismic reinforcement device for container storage yards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A container is placed on the placement steel frame. A connecting component and a reinforcement component are disposed on the placement steel frame. The connecting component includes a support fixedly connected to the side wall of the placement steel frame. A lock housing is installed on the top surface of the support. A lock head is rotatably connected inside the lock housing. A lock handle is fixedly connected to the lock head.

[0008] Preferably, the reinforcement component includes a groove formed in the side wall of the steel frame, a support column is fixedly connected to the side wall of the steel frame, a crank is rotatably connected to the support column, and an annular groove is formed in the crank groove.

[0009] Preferably, a limiting cavity is formed inside the slide groove, a sliding plate is slidably connected to the inner wall of the slide groove, a limiting block is fixedly connected to the bottom of the sliding plate, and the limiting block is slidably connected to the limiting cavity.

[0010] Preferably, a protruding rod is fixedly connected to the side of the sliding plate near the crank, the protruding rod slides in the annular groove, an iron chain is fixedly connected to the side wall of the sliding plate, and an iron hook is fixedly connected to the end of the iron chain away from the sliding plate.

[0011] Preferably, the interior of the lock handle is hollow, and a through groove is provided on the lock handle. A slide rod is slidably connected inside the lock handle, and a pull ring is fixedly connected to the top surface of the slide rod. A torsion spring is fixedly connected to the slide rod, and the end of the torsion spring away from the slide rod is fixedly connected to the lock handle.

[0012] Preferably, a hollow plate is fixedly connected to the side wall of the steel frame, a rotating shaft is rotatably connected to the side wall of the hollow plate, a rotating handle is fixedly connected to the side end of the rotating shaft, a threaded rod is rotatably connected inside the hollow plate, the threaded rod is fixedly connected to the rotating shaft, a sliding block is threadedly connected to the threaded rod, an insert rod is fixedly connected to the side wall of the sliding block, and a rectangular groove is formed on the insert rod.

[0013] Preferably, the seismic stabilizing component includes a support rod fixedly connected inside the groove, a buffer damper installed on the support rod, a connecting block fixedly connected to the buffer damper, a connecting rod hinged to the connecting block, a horizontal plate hinged to the end of the connecting rod away from the connecting block, a shock-absorbing spring installed on the bottom surface of the horizontal plate, and the shock-absorbing spring fixedly connected to the steel frame.

[0014] Preferably, the slide bar is inserted into the rectangular groove, and the insert rod is inserted into the through groove.

[0015] Preferably, the container is fixedly connected to a corner piece, which is divided into two groups, upper and lower. One group of corner pieces has a main hole on its bottom surface, through which the corner piece is inserted into a lock head. The other group of corner pieces has a through hole on its top surface, through which the containers are connected to each other.

[0016] Preferably, the sidewalls of the corner pieces are provided with elongated slots, and the iron hooks are inserted into the elongated slots.

[0017] The present invention has the following beneficial effects:

[0018] 1.

[0019] 2. By setting up a reinforcement component, the present invention drives the iron hook to firmly hook into the long slot of the corner piece at the bottom of the container, thereby limiting the container in the horizontal direction. At the same time, it works in concert with the connecting component to achieve bidirectional fixation of the container, further strengthening the connection strength between the container and the steel frame, and improving the container's anti-overturning ability when placed.

[0020] 3. This invention utilizes the shock-absorbing components, taking advantage of the elastic deformation of the shock-absorbing springs and the energy dissipation effect of the buffer damper, to achieve initial buffering of the impact force during the container placement stage. When encountering strong vibrations, the buffer damper can be compressed and dissipated through the linkage, quickly converting the vibration kinetic energy into heat energy and other forms of dissipation, stabilizing the container's posture, and reducing the impact of vibrations on the container and its internal cargo.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Example 1:

[0032] Reference Figures 1 to 8 An anti-seismic reinforcement device for a container stacking yard includes a steel frame 1, a groove 2 on the steel frame 1, an anti-seismic component 3 inside the groove 2, a container 4 placed on the steel frame 1, a connecting component 5 and a reinforcement component 6 on the steel frame 1, the connecting component 5 including a support 51 fixedly connected to the side wall of the steel frame 1, a lock housing 52 installed on the top surface of the support 51, a lock head 53 rotatably connected inside the lock housing 52, and a lock handle 54 fixedly connected to the lock head 53.

[0033] The interior of the lock handle 54 is hollow, and a through groove 55 is provided on the lock handle 54. A slide rod 56 is slidably connected inside the lock handle 54. A pull ring 58 is fixedly connected to the top surface of the slide rod 56. A torsion spring 57 is fixedly connected to the slide rod 56. The end of the torsion spring 57 away from the slide rod 56 is fixedly connected to the lock handle 54.

[0034] A hollow plate 59 is fixedly connected to the side wall of the steel frame 1. A rotating shaft 510 is rotatably connected to the side wall of the hollow plate 59. A rotating handle 511 is fixedly connected to the side end of the rotating shaft 510. A threaded rod 512 is rotatably connected inside the hollow plate 59. The threaded rod 512 is fixedly connected to the rotating rod. A sliding block 513 is threaded onto the threaded rod 512. An insert rod 514 is fixedly connected to the side wall of the sliding block 513. A rectangular groove 515 is formed on the insert rod 514. A sliding rod 56 is inserted into the rectangular groove 515, and the insert rod 514 is inserted into the through groove 55.

[0035] In this embodiment, firstly, the steel frame 1 is installed at the required location, such as the hardened ground of the storage yard, using expansion bolts and other fasteners to complete the positioning and fixing of the main body of the device. Then, the container 4 to be stacked is hoisted to the top of the steel frame 1 using a lifting device and slowly lowered to the bearing area of ​​the steel frame 1 (aligned with the horizontal plate 35). At this time, the image sensor preset on the steel frame 1 will identify the position of the bottom corner pieces 41 of the container 4 in real time, assisting the lifting device to accurately adjust the position of the container 4, ensuring that the main holes at the bottom of the four corner pieces 41 (lower group of corner pieces 41) of the container 4 are accurately aligned with the lock housing 52 on the side wall support 51 of the steel frame 1, and the corner pieces 41 are inserted into the lock housing 52 through the main holes.

[0036] After the container 4 is initially positioned, the staff turns the lock handle 54, which causes the lock head 53 inside the lock housing 52 to rotate synchronously, so that the lock head 53 engages with the inner wall groove of the main hole of the corner piece 41, thereby fixing the container 4 to the lock housing 52.

[0037] However, since the lock handle 54 is not limited, after long-term placement, external factors (such as wind or minor impacts) can easily cause the lock handle 54 to rotate, which in turn can loosen the connection between the lock head 53 and the corner piece 41, affecting the stability of the container 4. Therefore, the lock handle 54 needs to be locked and fixed by the connecting component 5.

[0038] Specifically, rotating the handle 511 drives the rotating shaft 510 to rotate, and the threaded rod 512 fixed to the rotating shaft 510 then rotates within the hollow plate 59. Since the top of the hollow plate 59 is open, it provides a limiting guide for the sliding block 513 connected to its internal threads. The sliding block 513 cannot rotate synchronously with the threaded rod 512, but only slides linearly along the inner wall of the hollow plate 59 towards the lock handle 54. When the sliding block 513 moves, the insert rod 514 fixedly connected to its side wall will move towards the lock handle 54 synchronously, so that the end of the insert rod 514 aligns with the through hole on the lock handle 54.

[0039] When the insertion rod 514 extends into the lock handle 54 through the through hole, the inclined end of the insertion rod 514 and the bottom of the slide rod 56 inside the lock handle 54 are arc-shaped. When they come into contact, the inclined surface of the insertion rod 514 applies an upward pushing force to the slide rod 56, causing the slide rod 56 to slide upward and compress the torsion spring 57. At this time, the insertion rod 514 continues to move along the bottom surface of the slide rod 56. As the sliding block 513 moves continuously, when the rectangular groove 515 on the insertion rod 514 is aligned with the bottom of the slide rod 56, the pushing force of the insertion rod 514 on the slide rod 56 disappears. Under the elastic reset action of the torsion spring 57, the slide rod 56 falls rapidly and gets stuck in the rectangular groove 515, thereby limiting the position of the insertion rod 514 and preventing the lock handle 54 from rotating unexpectedly under the influence of external factors such as wind impact and ground vibration, ensuring a stable connection between the lock head 53 and the corner fitting 41 of the container 4.

[0040] When it is necessary to release the limiting relationship between the insertion rod 514 and the lock handle 54, by pulling the handle at the top of the slide rod 56, the slide rod 56 is driven to slide upward and compress the torsion spring 57. At this time, the slide rod 56 gradually disengages from the rectangular groove 515 on the insertion rod 514. Then, the operator rotates the handle 511, which drives the threaded rod 512 to rotate in the opposite direction, drives the sliding block 513 to reset, and then drives the insertion rod 514 to slide out of the through groove 55 on the lock handle 54, thereby releasing the limiting constraint on the lock handle 54.

[0041] If two or more layers of containers 4 need to be stacked, first install the semi-automatic twist lock in the corner piece 41 (upper corner piece 41) at the bottom of the container 4 to be stacked. Then, use a lifting device to lift the container 4 directly above the container 4 that has been fixed in the steel frame 1, so that the semi-automatic twist lock at the bottom of the container 4 to be stacked is aligned with the through hole of the corner piece 41 (upper corner piece 41) at the top of the lower container 4. During the lowering process, the semi-automatic twist lock will automatically engage with the through hole of the lower corner piece 41, completing the vertical fixation of the two containers 4. When the container 4 is stacked to a high height, it can be fixed by using the long slots on the side wall of the corner piece 41, in conjunction with auxiliary equipment such as steel cables and tensioners, to further enhance the connection strength between the multi-layer containers 4 and improve the overall stacking stability.

[0042] Example 2:

[0043] Reference Figures 5-6 , Figure 7 This embodiment also has the following further features: the reinforcing component 6 includes a groove 61 formed on the side wall of the steel frame 1, a support column 62 is fixedly connected to the side wall of the steel frame 1, a crank 63 is rotatably connected to the support column 62, and an annular groove 64 is formed on the groove of the crank 63.

[0044] A limiting cavity 610 is provided inside the slide groove 61. A sliding plate 65 is slidably connected to the inner wall of the slide groove 61. A limiting block 69 is fixedly connected to the bottom of the sliding plate 65. The limiting block 69 is slidably connected to the limiting cavity 610.

[0045] A protruding rod 66 is fixedly connected to the side of the sliding plate 65 near the crank 63. The protruding rod 66 slides in the annular groove 64. An iron chain 67 is fixedly connected to the side wall of the sliding plate 65. An iron hook 68 is fixedly connected to the end of the iron chain 67 away from the sliding plate 65.

[0046] In this embodiment, after the worker completes the fixing operation of the lock handle 54, the iron hook 68 is hooked into the long slot hole on the side wall of the corner piece 41 to initially limit the horizontal displacement of the container 4 and prevent the container 4 from shifting laterally under subsequent operations or slight external forces.

[0047] At this time, as the sliding block 513 slides towards the lock handle 54, the position of the crank 63 hinged to it also changes synchronously: since the crank 63 is rotatably connected to the support column 62, when the sliding block 513 pushes the crank 63, the crank 63 will rotate around the hinge point with the support column 62 as the fulcrum. During the rotation of the crank 63, the annular groove 64 on its outer wall will move synchronously, and the protruding rod 66 that passes through the annular groove 64 will slide along the groove trajectory under the guidance of the annular groove 64; since the protruding rod 66 is fixedly connected to the sliding plate 65, and the limiting block 69 at the bottom of the sliding plate 65 is fitted into the limiting cavity 610 of the device (it can only move linearly back and forth along the limiting cavity 610), the sliding plate 65 will move along the groove 2 in the opposite direction to the sliding block 513. When the sliding plate 65 moves in the opposite direction, the chain connected to its side wall will drive the locking hook to move synchronously, so that the locking hook will tightly hook into the long slot on the side of the corner piece 41, and firmly lock the corner piece 41 of the container 4, further strengthening the connection strength between the container 4 and the steel frame 1, and restricting the displacement of the container 4 in both vertical and horizontal directions.

[0048] Example 3:

[0049] like Figure 1 , Figure 2 and Figure 4 As shown, compared to Embodiment 1 and Embodiment 2, in this embodiment, the seismic component 3 includes a support rod 31 fixedly connected inside the groove 2, a buffer damper 32 installed on the support rod 31, a connecting block 33 fixedly connected to the buffer damper 32, a connecting rod 34 hinged to the connecting block 33, a horizontal plate 35 hinged to the end of the connecting rod 34 away from the connecting block 33, a shock-absorbing spring 36 installed on the bottom surface of the horizontal plate 35, and the shock-absorbing spring 36 fixedly connected to the steel frame 1.

[0050] In this embodiment, when container 4 is hoisted and lowered, its bottom first contacts the horizontal plate 35. Its own weight will push the horizontal plate 35 to move slightly downward, simultaneously compressing the shock-absorbing spring 36 between the horizontal plate 35 and the steel frame 1. The shock-absorbing spring 36 absorbs the impact force of the lowering through elastic deformation, completing the buffering during the placement stage, and distributing the weight of container 4. In normal slight vibration scenarios, after the vibration is transmitted from the main body of the device to the shock-absorbing spring 36, the spring converts the kinetic energy of the slight vibration into elastic potential energy through the reciprocating elastic motion of compression and rebound, weakening the transmission of vibration to container 4. However, when encountering strong vibration, the large sway of container 4 will cause the horizontal plate 35 to move back and forth. If the horizontal plate 35 moves downward significantly, the connecting rod 3 hinged at its bottom will... 4 will swing inward into the groove 2 with the hinge point as the fulcrum, pushing the connecting block 33 at the other end of the connecting rod 34 to squeeze the buffer damper 32 on the support rod 31 in the groove 2. The buffer damper 32 converts the vibration kinetic energy into heat energy dissipation through the internal damping structure. At the same time, the rebound potential energy of the shock absorber spring 36 will cooperate with the reset structure of the buffer damper 32 to drive the horizontal plate 35, connecting rod 34, and connecting block 33 to reset smoothly, and also weaken the reciprocating oscillation of the spring rebound. After the external vibration disappears, the shock absorber spring 36 gradually releases its potential energy to make the horizontal plate 35 return to the initial bearing position, and the buffer damper 32 uses damping force to make the connecting rod 34 and connecting block 33 reset smoothly, finally making the container 4 return to a stable state, realizing the vibration protection of the container 4 in all scenarios.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
