For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0036] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0037] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0038] In the segmented production of the grooved wall section of a bulk carrier, in order to avoid the need for scaffolding during construction, reduce the construction difficulty and shorten the construction period, such as Figures 1-8 As shown, the present invention provides a trench wall work ladder. The trench wall work ladder comprises a climbing ladder 1, a straight ladder 2, a protective frame 3 and a fixing assembly 4.

[0039] The ladder 1 is tilted vertically and supported on the inclined surface of the triangular cabin segment 100. Two sets of guardrails 11 are spaced apart along the ladder 1's extension direction. A vertical ladder 2 is positioned at the top of the ladder 1 and is capable of rotating relative to the ladder 1. A protective frame 3 is fixed to the ladder 2, forming a climbing passage with the frame. A fixing assembly 4 is mounted on the frame 3 and is used to connect to the triangular cabin segment 100 and the tank wall segment 200 to secure the ladder 2.

[0040] During construction, the trench wall tooling ladder is hoisted onto the triangular cabin segment 100. The climbing ladder 1 corresponds to the inclined surface of the triangular cabin segment 100, and the straight ladder 2 corresponds to the straight section of the triangular cabin segment 100. The fixing component 4 is used to connect the protective frame 3 with the triangular cabin segment 100 and the trench wall segment 200, thereby fixing the protective frame 3. The staff only needs to use the climbing ladder 1 and the straight ladder 2 to carry out the docking construction of the triangular cabin segment 100 and the trench wall segment 200. In this way, there is no need to set up scaffolding during the construction process, which reduces the construction difficulty and shortens the construction period. In addition, by providing the protective frame 3 and the guardrail 11, it can play a role in safety protection during the process of personnel climbing construction.

[0041] In some embodiments, the fixing assembly 4 includes a first tie rod 41 and a first support rod 42. The first tie rod 41 is rotatably mounted on the protective frame 3. A plurality of first teeth 411 are provided on the end of the first tie rod 41 remote from the protective frame 3. The first tie rod 41 is connected to the triangular cabin segment 100 via the first teeth 411. The first end of the first support rod 42 is rotatably coupled to the first tie rod 41, while the second end of the first support rod 42 is rotatably coupled to the protective frame 3. The first support rod 42 provides support for the first tie rod 41. The first tie rod 41 is connected to the triangular cabin segment 100 via the first teeth 411, thereby connecting the protective frame 3 to the triangular cabin segment 100. To further enhance the stability of the connection between the first tie rod 41 and the triangular cabin segment 100, after the first tie rod 41 is connected to the triangular cabin segment 100, bolts are passed through the first tie rod 41 to further enhance stability and prevent safety accidents.

[0042] In some embodiments, a first slot 412 is defined on the first tie rod 41 along its extension direction, and a second slot 31 is defined on the protective frame 3 along its vertical direction. A first fastener is inserted into the first slot 412 and connected to the first end of the first support rod 42, while a second fastener is inserted into the second slot 31 and connected to the first tie rod 41. During the connection between the first tie rod 41 and the triangular cabin segment 100, the height of the first tie rod 41 and the position of the first support rod 42 relative to the first slot 412 need to be adjusted as needed, thereby adjusting the angle of the first tie rod 41. The second fastener is then used to lock the first tie rod 41 relative to the second slot 31, and the first fastener is used to lock the support rod relative to the first slot 412. In this manner, the position of the first tie rod 41 can be set for triangular cabin segments 100 of different heights, thereby improving adaptability.

[0043] In some embodiments, the fixing assembly 4 includes a second tie rod 44 and a third tie rod 43. Both the second tie rod 44 and the third tie rod 43 are rotatably connected to the protective frame 3. The second tie rod 44 is provided with a plurality of second teeth, and the third tie rod 43 is provided with a plurality of third teeth 431. The second tie rod 44 is connected to the triangular cabin segment 100 via the second teeth, and the third tie rod 43 is connected to the trough wall segment 200 via the third teeth 431. By providing the second tie rod 44 and the third tie rod 43, the trough wall tooling ladder can be further connected to the triangular cabin segment 100 and the trough wall segment 200, thereby fixing the trough wall tooling ladder from different angles, ensuring that the trough wall tooling ladder will not separate from the triangular cabin segment 100 and the trough wall segment 200 during construction, thereby ensuring construction safety.

[0044] In some embodiments, a plurality of stoppers 32 are fixedly mounted on one side of the protective frame 3 facing the tank wall section 200. The stoppers 32 are spaced apart along the extension direction of the protective frame 3. When the tank wall work ladder is placed, the stoppers 32 abut against the tank wall section 200, thereby spacing the protective frame 3 from the tank wall section 200 and forming a passage for a welding robot between the tank wall section 200 and the protective frame 3. This facilitates the use of the welding robot to perform welding operations at the welding locations between the tank wall section 200 and the triangular cabin segment 100.

[0045] In some embodiments, multiple horizontal work platforms 21 are spaced apart along the extension of the vertical ladder 2. The horizontal work platforms 21 are connected to the steps of the vertical ladder 2 and the protective frame 3. The horizontal work platforms 21 provide convenient places for workers to rest or place their belongings. They also facilitate operations such as welding on the horizontal work platforms 21.

[0046] In some embodiments, a movable cover 22 is pivotally mounted on the side of the horizontal work platform 21 facing the tank wall section 200. The movable cover 22 can be deployed or retracted. By pivoting the movable cover 22, workers can deploy it when they need to rest or place their belongings, ensuring that the horizontal work platform 21 has sufficient space for storing belongings and resting. When welding with a welding robot, the movable cover 22 needs to be pivoted and retracted to avoid interference with the welding robot.

[0047] In some embodiments, a plurality of support and discharge racks 13 are spaced apart along the extension direction of the ladder 1 on a side of the ladder 1 away from the slot wall section 200. Since welding wire needs to be supplied in real time during operation of the welding robot, the support and discharge racks 13 allow welding wire coils to be placed on the support and discharge racks 13, thereby providing the welding robot with a real-time supply of welding wire and ensuring smooth welding operations.

[0048] In some embodiments, multiple support platforms 14 are spaced apart along the extension direction of the ladder 1 on the side of the ladder 1 facing the tank wall section 200. The multiple support platforms 14 are rotatably connected to the ladder 1 and can be deployed to abut against or retract against the surface of the tank wall section 200. When manual operation is required, the support platforms 14 are rotated so that they overlap the surface of the tank wall section 200, and the operator can then step on the support platforms 14 to perform the operation. When the support platforms 14 are no longer needed, they can simply be rotated away from the wall surface, so that the wall surface does not interfere with the movement of the welding robot.

[0049] In some embodiments, an anti-slip part 12 is provided on the side of the ladder 1 facing the triangular cabin segment 100. Specifically, a plurality of anti-slip parts 12 are provided at intervals along the extension direction of the ladder 1. By providing the anti-slip part 12, the ladder 1 can be supported, and the friction between the ladder 1 and the triangular cabin segment 100 can be increased, thereby limiting the position of the ladder 1 on the triangular cabin segment 100. In this embodiment, in order to further facilitate the anti-slip part 12 to adapt to triangular cabin segments 100 with different slopes, the anti-slip part 12 is rotatably provided on the ladder 1. For triangular cabin segments 100 with different slopes, the angle of the anti-slip part 12 is adjusted to achieve the installation of the ladder 1. Furthermore, anti-slip rubber can be provided on the side of the anti-slip part 12 facing the triangular cabin segment 100 to further increase the friction and enhance the anti-slip effect.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
