Technical Field

[0001] This utility model belongs to the field of mechanical design and manufacturing technology, and in particular relates to a protective structure for container top operations. Background Technology

[0002] Container ship crew members often perform lashing and dismantling operations on top of containers that are tens of meters high. The working position is high, and if they are not careful, they can fall from the top of the container, which can cause serious injury or death. In recent years, there have been frequent accidents involving crew members falling from heights during lashing or dismantling operations on container ships, both domestically and internationally, causing great losses to the lives of crew members and their families.

[0003] The container roof and sides lack fixed fastening points, making it impossible to secure safety ropes. Crew members lack stable support for their hands and bodies while working, making it difficult to effectively ensure their safety. For example, some movable guardrails installed on containers are not strong enough and are easily damaged. Installation requires space and is cumbersome. Welded mesh panels or shaped perforated panels require more manpower, are more expensive, and are inconvenient to construct. Summary of the Invention

[0004] In response to the above situation, in order to overcome the shortcomings of existing technology in effectively securing safety ropes.

[0005] The technical solution adopted by this utility model is as follows: a protective structure for container top operation, including a ladder and a traction component set on the ladder, the traction component being used to assist the operator in traction; the ladder is provided with a fastening component.

[0006] Furthermore, the traction assembly includes a bracket, a support rod, a slider, and an auxiliary wheel. The bracket is fixed to the upper end of the ladder, the support rod is fixed to the side of the bracket, a groove is provided on the inner side of the support rod, the slider is slidably disposed inside the groove, a collar is fixedly connected to the lower end of the slider, the auxiliary wheel is rotatably disposed on the slider, a fall arrestor is sleeved on the collar, and a safety rope is connected to the lower end of the fall arrestor.

[0007] Furthermore, the fastening assembly includes a fixing block, a positioning post, and a pull ring. The fixing block is fixed to the side of the ladder body, and a positioning groove is provided on the fixing block. The positioning post is inserted into the positioning groove, the pull ring is fixed to the upper end of the positioning post, and a plurality of positioning holes are provided at the lower part of the positioning post.

[0008] Furthermore, the bracket is made of a square hollow frame welded together, and the lower end of the bracket is welded to the upper end of the ladder.

[0009] Furthermore, the slider is I-shaped, the inner side of the groove is T-shaped to match the upper end of the slider, and the lower end of the auxiliary wheel is in contact with the bottom end of the inner side of the groove.

[0010] Furthermore, the positioning post is a cuboid at the top and a cylinder at the bottom, and the positioning groove is adapted to the outer side of the positioning post.

[0011] Furthermore, the bottom of the ladder is provided with several casters, which are either locked or non-locked casters.

[0012] The beneficial effects of this utility model after adopting the above structure are as follows:

[0013] By linking the sliding grooves and I-shaped sliders within the bracket and support rod, the safety rope is slidably fixed, and the fall arrestor enhances the traction protection of the safety rope, thereby effectively protecting the personnel working on top of the container.

[0014] The ladder is connected to the container's top corner fittings via fixing blocks and positioning posts on the side of the ladder, and secured using the container's existing lifting holes, thereby enhancing the stability of the ladder and effectively improving the stability of auxiliary traction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0027] like Figure 1 As shown, a protective structure for container top operations includes a ladder 1 and a traction component disposed on the ladder 1, the traction component being used to assist in traction of the operator; a fastening component is provided on the ladder 1.

[0028] like Figure 2-3 As shown in Figure -5, the traction assembly includes a bracket 2, a support rod 3, a slider 4, and an auxiliary wheel 5. The bracket 2 is fixed to the upper end of the ladder 1, the support rod 3 is fixed to the side of the bracket 2, a groove is provided on the inner side of the support rod 3, the slider 4 is slidably disposed in the groove, a collar 6 is fixed to the lower end of the slider 4, the auxiliary wheel 5 is rotatably disposed on the slider 4, a fall arrestor 7 is sleeved on the collar 6, and a safety rope is connected to the lower end of the fall arrestor 7.

[0029] The bracket 2 is a square hollow frame welded together. The lower end of the bracket 2 is welded to the upper end of the ladder 1. The slider 4 is set in an I-shape. The inner side of the slide groove is set in a T-shape to match the upper end of the slider 4. The lower end of the auxiliary wheel 5 is in contact with the bottom end of the inner side of the slide groove. The auxiliary wheel 5 improves the stability of the slider 4 when sliding in the slide groove. In use, the operator is pulled by the safety rope. As the operator moves, the I-shaped slider 4 slides in the slide groove, which effectively fixes the sliding of the safety rope and increases the operator's working range. The fall arrestor 7 between the collar 6 and the safety rope strengthens the traction protection of the safety rope, thereby achieving effective protection for the operator working on the top of the container.

[0030] like Figure 2-4 As shown in -6-8, the fastening assembly includes a fixing block 8, a positioning post 9, and a pull ring 10. The fixing block 8 is fixed to the side of the ladder body 1. A positioning groove is provided on the fixing block 8. The positioning post 9 is inserted into the positioning groove. The pull ring 10 is fixed to the upper end of the positioning post 9. Several positioning holes are provided at the lower part of the positioning post 9.

[0031] The positioning post 9 is a cuboid at the top and a cylinder at the bottom. The positioning groove matches the outer side of the positioning post 9. The bottom of the ladder 1 is equipped with several casters, which are both locked and unlocked. Before operation, the fixing block 8 of the ladder 1 is moved to the top of the original lifting hole of the container. The positioning post 9 is inserted into the positioning groove and the lifting hole in sequence, and the positioning post 9 is fixed to the lifting hole with the fixing bolt. Then, the bottom of the ladder 1 is fixed by the locked casters. The original lifting hole of the container is used for fixing, which does not require damaging the container body, strengthens the stability of the ladder 1, and effectively improves the stability of auxiliary traction.
