Description

Technical Field

[0001] This application relates to the field of tank container technology, and more particularly to a remote-controlled handrail and a tank container having the same. Background Technology

[0002] Tank containers are equipped with maintenance walkways on top to facilitate the inspection, maintenance, and operation of equipment on the tank top by staff. In existing technologies, the handrails accompanying these walkways are mostly fixed structures that cannot be folded for storage. During container transportation, stacking, and storage, these external fixed handrails occupy a large amount of space and are prone to collisions, deformation, and damage, affecting container transfer efficiency. Simultaneously, some foldable handrails have simple designs and cumbersome operation methods, requiring staff to manually disassemble and manipulate the handrails on the walkway, which is inconvenient for high-altitude operations and poses a high safety risk, failing to meet the needs of both transportation storage and operational safety. Therefore, a new technical solution is urgently needed to address at least one of these technical problems. Summary of the Invention

[0003] In view of the above shortcomings, one objective of this application is to provide a remote-controlled handrail that can be remotely controlled to fold and unfold, is easy to operate, occupies little space when stored, and has high operational safety. Another objective of this application is to provide a tank container equipped with a remotely foldable handrail, which can be folded and stored in the transport state and quickly unfolded for use in the maintenance state, adapting to the needs of tank container transshipment and high-altitude operations.

[0004] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted in this application is as follows: A remote-controlled handrail, comprising: Climbing ladders; Folding handrail components installed in walkway components; Remote control transmission components; A linkage component, which is connected to the folding armrest assembly; The control element is rotatably mounted on the ladder. By rotating the control element, the folding handrail assembly can be switched to a folded state or an open state via the remote control transmission element and the linkage element.

[0005] Furthermore, when the folding handrail assembly is in the open state, the connection point between the remote control transmission component and the linkage component is located below the walkway assembly.

[0006] Furthermore, the linkage component is a curved ring structure.

[0007] Furthermore, the linkage includes a linkage upper rod, a linkage tilting rod, a linkage bottom rod, a linkage direction-changing transition rod, and a linkage connecting rod connected in sequence, with the linkage tilting rod extending downward.

[0008] Furthermore, the folding handrail assembly includes a folding rotating side rod, which is rotatably connected to the walkway assembly.

[0009] Furthermore, the folding armrest assembly also includes multiple folding rotating rods and a first longitudinal rod, wherein the first longitudinal rod is rotatably connected to the folding rotating side rod and the folding rotating rod respectively.

[0010] Furthermore, the folding armrest assembly also includes a second longitudinal bar, which is rotatably connected to the folding rotating side bar and the folding rotating rod, respectively.

[0011] Furthermore, the remote control transmission component is provided with a first pivot structure and a second pivot structure at both ends.

[0012] Furthermore, the first pivot structure includes a pivot lug connected to the linkage member, a first pivot portion disposed at one end of the remote control transmission member, and a first pivot shaft inserted into the pivot lug and the first pivot portion, wherein the first pivot portion is pivotally connected to the pivot lug via the first pivot shaft.

[0013] Furthermore, the second pivot structure includes a second pivot portion connected to the other end of the remote control transmission member and a second pivot shaft connected to the control member, wherein the second pivot portion is pivotally connected to the control member via the second pivot shaft.

[0014] Furthermore, the control element has a trapezoidal structure.

[0015] This application also provides a tank container, including a tank body, a walkway assembly, and the remote-controlled handrail, wherein the walkway assembly is connected to the tank body.

[0016] Compared with traditional technical solutions, the beneficial effects of this application are: 1) This application sets up an independent remote control structure, which allows staff to remotely control the folding and unfolding of the handrails from the ladder, without having to climb the walkway to operate manually, thus avoiding the risks of working at heights, making the operation convenient and efficient, and greatly improving the safety of tank top maintenance operations; 2) The linkage is a curved ring structure and an integral structure that fits the overall assembly layout. It is easy for workers to grip when climbing, improving comfort and safety. At the same time, compared with existing technologies, there are fewer turning points and the transmission path is simpler. 3) A sunken bottom transmission layout is achieved by using a linkage tilting rod, linkage bottom rod, linkage direction-changing transition rod, and linkage connecting rod. This optimizes the power transmission arm, reduces the length of the remote control transmission components, and directly reduces the operating force required to rotate the control components while ensuring both the folded and open states. 4) The folding handrail assembly adopts a multi-bar connection structure, which has strong overall structural stability. When unfolded, it can form a reliable protective handrail. When folded, it fits the walkway layout and occupies very little space, effectively avoiding the problem of handrail damage during container transportation and stacking. 5) A linkage transmission structure is formed by remote control transmission components and linkage components. The transmission is precise and the operation is smooth. It can realize the rapid switching of the handrail state. The structure is simple and the failure rate is low. 6) The walkway components are equipped with bottom reinforcing bars and support components, with high overall load-bearing strength, which can provide a stable installation foundation for the folding handrail components and is suitable for the long-term outdoor transportation and use of tank containers.

[0019] The present application will now be further described with reference to the accompanying drawings.

[0020] In the accompanying drawings of the embodiments of this application, the same or similar reference numerals correspond to the same or similar components. In the description of this application, it should be understood that if terms such as "top", "bottom", "left", "right", "front", "rear", "inner", "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this application, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0021] Please refer to Figures 1-8 This application provides a remote-controlled handrail in one embodiment. The handrail is installed on the outside of a tank body of a tank container. The handrail includes a ladder 1, a folding handrail assembly 2, a linkage 3, a remote control transmission component 4, and an operating component 5. A walkway assembly 6 is installed on the top of the tank body. The folding handrail assembly 2 is mounted on the walkway assembly 6 and can be folded and unfolded with the operating action. The linkage 3 is fixedly connected to the folding handrail assembly 2 and is used to transmit transmission power. The remote control transmission component 4 is pivotally connected to the operating component 5 and the linkage 3 at both ends, forming a linkage transmission structure. The operating component 5 is rotatably mounted on the ladder 1. By rotating the operating component 5, the operator can synchronously drive the folding handrail assembly 2 via the remote control transmission component 4 and the linkage 3, switching between folding / folding and unfolding protective states. This application provides an independent remote control structure, allowing operators to remotely control the folding and unfolding of the handrail from the ladder 1 position without having to manually operate it from the walkway, avoiding the risks of working at heights, and providing convenient and efficient operation, significantly improving the safety of tank top maintenance operations.

[0022] Some tank container ladders are foldable, and the handrails open simultaneously with the ladder. However, most tank container ladders are fixed and cannot be folded, making it impossible to open the handrails. The technical solution of this application installs the control component 5 on the ladder 1 body, so that even if the ladder 1 cannot be folded, the handrails can be folded or opened remotely.

[0023] like Figures 1-8 As shown, when the folding handrail assembly 2 is fully opened, the connection point between the remote control transmission component 4 and the linkage component 3 is located below the walkway assembly 6, that is, the connection point between the remote control transmission component 4 and the linkage component 3 is located below the bottom surface of the walkway assembly 6, making it easier to operate.

[0024] like Figures 1-8As shown, the linkage 3 is a curved ring structure. The linkage is an integral structure that fits the overall assembly layout. It is easy for workers to grip when climbing, improving comfort and safety. At the same time, compared with the existing technology, there are fewer rotation points and the transmission path is simpler.

[0025] like Figures 1-8 As shown, the linkage 3 includes a linkage upper rod 301, a linkage tilting rod 302, a linkage bottom rod 303, a linkage direction-changing transition rod 304, and a linkage connecting rod 305 connected in sequence. The linkage tilting rod 302 extends downward, and the linkage bottom rod 403 is connected to the remote control transmission component 4. The linkage upper rod 301, linkage tilting rod 302, linkage bottom rod 303, linkage direction-changing transition rod 304, and linkage connecting rod 305 realize a sunken bottom transmission layout, optimize the transmission arm, reduce the length of the remote control transmission component, and directly reduce the operating force required to rotate the control component 5 while ensuring the folded and open states, thereby improving the torque transmission efficiency.

[0026] Furthermore, when the remote control armrest is in the open state, the control element 5 and the linkage base rod 303 form an angle α, which is an obtuse angle. When the control lever 5 is rotated, and the remote control armrest is in an intermediate state between the folded state and the open state, the control element 5 is perpendicular to the linkage base rod 303, making operation the least effort.

[0027] like Figures 1-8 As shown, the folding handrail assembly 2 includes a folding rotating side rod 21, multiple folding rotating rods 22, a first longitudinal rod 23, and a second longitudinal rod 24. The folding rotating side rod 21 is rotatably connected to the side wall of the walkway assembly 6, providing a rotation reference for the overall folding action. The first longitudinal rod 23 and the second longitudinal rod 24 are rotatably connected to the folding rotating side rod 21 and each folding rotating rod 22, respectively. The multiple rods are connected to form an integral protective frame. When unfolded, the structure is stable and can provide reliable protection for the staff on the walkway. When folded, the rods fit together, greatly reducing the space occupied.

[0028] like Figures 1-8 As shown, the remote control transmission component 4 has a first pivot structure and a second pivot structure at both ends, respectively, to achieve flexible pivoting cooperation at both ends and ensure that the transmission process is smooth and unimpeded. The first pivot structure includes a pivot ear plate 41, a first pivot part 42, and a first pivot shaft 43. The pivot ear plate 41 is fixedly connected to the linkage component 3. The first pivot part 42 is integrally disposed at one end of the remote control transmission component 4. The first pivot shaft 43 is inserted and assembled in the assembly hole of the pivot ear plate 41 and the first pivot part 42, so that the first pivot part 42 can rotate flexibly relative to the pivot ear plate 41, realizing the hinged cooperation between the remote control transmission component 4 and the linkage component 3. It is worth noting that the first pivot part 42 can also be omitted, and the upper end of the remote control transmission component 4 can be directly connected to the pivot ear plate 41.

[0029] like Figures 1-8 As shown, specifically, the remote control transmission component 4 is a cylindrical or flat rod-shaped structure.

[0030] like Figures 1-8 As shown, the second pivot structure includes a second pivot portion 44 and a second pivot shaft 45. The second pivot portion 44 is disposed at the other end of the remote control transmission component 4, and the second pivot shaft 45 is through-mounted in the second pivot portion 44, allowing the second pivot portion 44 to pivot flexibly relative to the operating component 5, thereby achieving a hinged connection between the remote control transmission component 4 and the operating component 5. The double-pivot structure at both ends ensures the flexibility and stability of the overall transmission. Specifically, the first pivot portion 42 is a U-shaped plate structure, and the second pivot portion 44 is a sleeve structure.

[0031] like Figures 1-8 As shown, the control component 5 has a trapezoidal structure, which makes it easier for workers to climb when used with the ladder 1. The control component 5 can also be a single-bar structure, which can be flexibly selected according to the actual installation space and usage requirements.

[0032] Please refer to Figures 2-3 This application also provides a tank container, including a tank body, a walkway assembly 6, and the aforementioned remote-controlled handrail. The walkway assembly 6 is fixedly connected to the outside of the tank body (not shown) for workers to walk and operate. The walkway assembly 6 includes a walkway slab 61 extending longitudinally along the tank body, a bottom reinforcing rod 62 fixedly disposed on the bottom side of the walkway slab 61, and at least one support member (not shown) disposed on the bottom side of the walkway slab 61. The lower end of the support member is fixedly connected to the outer wall of the tank body. The bottom reinforcing rod 62 enhances the overall structural strength of the walkway slab 61, and the support member 63 provides stable support for the walkway assembly 6. It has a strong load-bearing capacity, is not easily deformed, and is suitable for long-term outdoor operation conditions.

[0033] like Figure 2 and Figure 3 As shown, specifically, the outer side of the walkway slab 61 is provided with a folded edge, which is connected to a limiting plate 63. After the folding handrail assembly 2 is opened, the folding rotating edge rod 21 abuts against the limiting plate 63 to limit the movement, preventing the folding rotating edge rod 21 from rotating too much and avoiding the situation where the folding handrail assembly 2 folds in reverse, thus ensuring the stability and reliability of the handrail after it is unfolded.

[0034] like Figure 2 and Figure 3 As shown, specifically, the folding rotating edge rod 21 is rotatably connected to the folded edge, the bottom reinforcing rod 62 is connected to the support plate 64, the folding rotating rod 22 is rotatably connected to the support plate 64, the bottom reinforcing rod 62 is connected to at least one support plate 65, the first longitudinal rod 23 is located below the second longitudinal rod 24, and after folding, the first longitudinal rod 23 abuts against the support plate 65.

[0035] like Figure 2 and Figure 3 As shown, specifically, the bottom reinforcing rod 62 is a square tube or channel steel structure, the support member is a bent plate structure, the support member is detachably connected to the walkway plate, and at least one reinforcing ring is provided on the outer periphery of the tank body, and the support member is detachably connected to the reinforcing ring.

[0036] Specific working method: During the transfer and storage of tank containers, the staff rotates the control component 5 on the ground or ladder 1, which drives the linkage component 3 through the remote control transmission component 4. The linkage component 3 pulls the hinged rods of the folding handrail assembly 2 to rotate, so that the folding handrail assembly 2 is folded and stored in close contact with the walkway 61, reducing the overall space occupied and avoiding collision damage; when maintenance work needs to be carried out on the top of the tank, the control component 5 is rotated in the opposite direction, which drives the folding handrail assembly 2 to unfold and form a complete protective handrail, ensuring the safety of the staff working at height. The overall operation does not require climbing, is convenient and safe, and the state switching is efficient.
