DETAILED DESCRIPTION

[0025] To make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0026] The existing inclined ladder adopts a fixed form in which the upper and lower end ladder feet are connected with the hull structure, and there is no support at other positions. The vibration of the inclined ladder handrail position will increase with the increase of the inclined ladder, and a support structure needs to be added to reduce the vibration.

[0027] The embodiments of the present application provide a climbing ladder, which improves the stability of the inclined ladder and further reduces the vibration of the inclined ladder.

[0028] The following will be described in connection with the drawings in the specification Figures 1-8 The climbing ladder will be described in detail.

[0029] The present application provides a climbing ladder, which comprises: a support frame 1 comprising a first support rod 11, a second support rod 12 and a plurality of support plates 13, the first support rod 11 and the second support rod 12 are arranged in parallel, and each support plate 13 is arranged uniformly in the length direction of the first support rod 11 and the second support rod 12; a handrail frame 2 arranged on the support frame 1, comprising a first handrail 21 and a second handrail 22, the first handrail 21 is arranged on the first support rod 11, and the second handrail 22 is arranged on the second support rod 12; a fixing assembly 3, which is detachably connected with the support frame 1 and fixedly connected with a first target position and a second target position; and a reinforcing assembly 4, which is detachably connected with the handrail frame 2 and fixedly connected with a third target position and a fourth target position.

[0030] Specifically, the climbing ladder comprises a support frame 1, a handrail frame 2, a fixing assembly 3 and a reinforcing assembly 4. The support frame 1 comprises a first support rod 11, a second support rod 12 and a plurality of support plates 13. The first support rod 11 and the second support rod 12 are arranged in parallel. Each support plate 13 is arranged uniformly in the length direction of the first support rod 11 and the second support rod 12, forming a continuous rigid frame, which can disperse the dynamic load of the ladder body and suppress resonance. The handrail frame 2 is arranged on the support frame 1. The handrail frame 2 comprises a first handrail 21 and a second handrail 22. The first handrail 21 is arranged on the first support rod 11, and the second handrail 22 is arranged on the second support rod 12, forming a closed force ring to avoid lateral distortion caused by vibration. The fixing assembly 3 is detachably connected with the support frame 1 and fixedly connected with a first target position and a second target position. The support frame 1 can be detachably connected with the first target position and the second target position, respectively. The reinforcing assembly 4 is detachably connected with the handrail frame 2 and fixedly connected with a third target position and a fourth target position. The handrail frame 2 is connected with the third target position and the fourth target position, respectively, to form multi-point constraint, directly absorbing vibration energy and suppressing high-order vibration mode. The fixing assembly 3 and the reinforcing assembly 4 cooperate to further reduce the swing amplitude of the ladder.

[0031] Further, the first target position is a top support platform of the fixed ladder, the second target position is a bottom support platform of the fixed ladder, and the top support platform is higher than the bottom support platform. The third target position is a fixed bar arranged on the top support platform, and the fourth target position is a fixed bar arranged on the bottom support platform.

[0032] In some optional embodiments, the fixing assembly 3 comprises a plurality of fixing components 31. At least one fixing component 31 is detachably connected with the first support rod 11 and fixedly connected with the first target position. At least one fixing component 31 is detachably connected with the first support rod 11 and fixedly connected with the second target position. At least one fixing component 31 is detachably connected with the second support rod 12 and fixedly connected with the first target position. At least one fixing component 31 is detachably connected with the second support rod 12 and fixedly connected with the second target position.

[0033] Specifically, the at least one fixed component 31 is detachably connected with the first support rod 11 and fixedly connected with the top support platform, the at least one fixed component 31 is detachably connected with the first support rod 11 and fixedly connected with the bottom support platform, the at least one fixed component 31 is detachably connected with the second support rod 12 and fixedly connected with the top support platform, and the at least one fixed component 31 is detachably connected with the second support rod 12 and fixedly connected with the bottom support platform, so that the support frame 1 is detachably connected with the top support platform and the bottom support platform respectively, and the ladder can be conveniently installed or transferred in a narrow space without welding or permanent modification. The fixed component 31 is connected to the first target position and the second target position on the first support rod 11 and the second support rod 12 respectively, forming a quadrilateral fixed structure of “double-rod double-anchor”, which greatly reduces the risk of ladder body shaking and transverse displacement compared with the traditional inclined ladder which is only fixed at two ends. The first support rod 11 and the second support rod 12 are symmetrically fixed, which can resist the torque generated by the ship rolling or personnel climbing, and avoid the inclination of the inclined ladder caused by unilateral force. The multiple fixed components 31 transmit the vibration of the inclined ladder to different anchor points, disperse the energy through the ship structure, and suppress the resonance amplification effect. The first support rod 11 and the second support rod 12 are independently connected to the first target position and the second target position, dispersing the load of the inclined ladder to multiple anchor points, reducing stress concentration at a single connection point, and prolonging the service life.

[0034] In some optional embodiments, a bolt assembly 32 is further included, each fixed component 31 includes a first fixed plate 311, a first positioning plate 312, and the bolt assembly 32, the first fixed plate 311 is arranged on the first positioning plate 312, the first positioning plate 312 is arranged at the first target position or the second target position, and the bolt assembly 32 connects the first fixed plate 311 and the first support rod 11 or the second support rod 12.

[0035] Specifically, the first positioning plate 312 is fixed at the first target position or the second target position in advance, providing a reference mounting surface to ensure the centering of the ladder body and the anchor point. The first fixed plate 311 is connected with the first support rod 11 or the second support rod 12 through the bolt assembly 32, forming a rigid node to avoid micro-motion wear caused by traditional welding or simple binding. The axial locking force of the bolt assembly 32 directly transmits the load of the ladder body to the first positioning plate 312, significantly improving the ability of the node to resist transverse shear (such as ship rolling) and longitudinal tension (such as personnel climbing impact). The bolt assembly 32 serves as a universal connector, allowing quick disassembly with tools, without the need for professional welding or cutting, making it suitable for frequent moving scenarios.

[0036] In some optional embodiments, the first positioning plate 312 is welded with the first target position or the second target position, or the first positioning plate 312 is connected with the first target position or the second target position through a positioning element.

[0037] Specifically, the first positioning plate 312 is welded with the first target position or the second target position, so that the first positioning plate 312 is fused with the first target position or the second target position as a whole, eliminating the risk of micro-motion wear or looseness of the bolt assembly 32 connection, especially suitable for long-term fixation and high-vibration environment. After welding, the whole anti-corrosion treatment such as hot-dip galvanizing and anti-rust paint spraying can be carried out to avoid the gap corrosion problem at the connection of the bolt assembly 32, thereby prolonging the service life of the inclined ladder in a humid and salt spray environment. The first positioning plate 312 is welded with the first target position or the second target position, without the risk of bolt looseness, and is basically maintenance-free, suitable for occasions where frequent maintenance is difficult. The first positioning plate 312 is connected with the first target position or the second target position through the positioning element, avoiding the thermal influence of welding on the hull such as deformation and coating damage.

[0038] In some optional embodiments, the positioning element is a bolt fastener.

[0039] In some optional embodiments, the reinforcing assembly 4 includes a plurality of reinforcing components 41, at least one reinforcing component 41 is fixedly connected with the first handrail 21 and the third target position; at least one reinforcing component 41 is fixedly connected with the second handrail 22 and the fourth target position; at least one reinforcing component 41 is fixedly connected with the first handrail 21 and the third target position; and at least one reinforcing component 41 is fixedly connected with the second handrail 22 and the fourth target position.

[0040] Specifically, the first target position is a top support platform of the fixed inclined ladder, the second target position is a bottom support platform of the fixed inclined ladder, and the top support platform is higher than the bottom support platform. The third target position is a fixed bar arranged on the top support platform, and the fixed bar is provided with two, which are a first fixed bar 51 and a second fixed bar 52, and the first fixed bar 51 and the second fixed bar 52 are respectively located on both sides of the support frame 1. At least one reinforcing component 41 is fixedly connected with the first handrail 21 and one of the fixed bars, and at least one reinforcing component 41 is fixedly connected with the second handrail 22 and the other fixed bar. The fourth target position is a fixed bar arranged on the bottom support platform, and the fixed bar is provided with two, which are a third fixed bar 61 and a fourth fixed bar 62, and the third fixed bar 61 and the fourth fixed bar 62 are respectively located on both sides of the support frame 1. At least one reinforcing component 41 is fixedly connected with the first handrail 21 and one of the fixed bars, and at least one reinforcing component 41 is fixedly connected with the second handrail 22 and the other fixed bar.

[0041] Further, the fixing component 31 at the top of the first handrail 21 and the second handrail 22 mainly bears tensile force to prevent the inclined ladder from tilting backward. The fixing component 31 at the bottom of the first handrail 21 and the second handrail 22 mainly bears compressive force to prevent the inclined ladder from slipping. The reinforcing assembly 4 is detachably connected with the handrail frame 2 and fixedly connected with the third target position and the fourth target position. The handrail frame 2 is connected with the third target position and the fourth target position to form multi-point constraint, directly absorbing vibration energy, especially inhibiting high-order vibration mode. The fixing assembly 3 and the reinforcing assembly 4 cooperate to further reduce the swing amplitude of the inclined ladder.

[0042] In some optional embodiments, the reinforcing component 41 includes a second fixing plate 411, a third fixing plate 412, a limiting ring 413 and a fixing bolt 414. The fixing bolt 414 connects the second fixing plate 411 and the third fixing plate 412. The second fixing plate 411 is connected with the third target position and the fourth target position. The limiting ring 413 is connected with the first handrail 21 or the second handrail 22 and the third fixing plate 412.

[0043] Specifically, the second fixing plate 411 and the third fixing plate 412 form an adjustable clamping structure through the fixing bolt 414.

[0044] In some optional embodiments, the second fixing plate 411 is uniformly provided with a plurality of second through holes in the length direction of the second fixing plate 411. The third fixing plate 412 is uniformly provided with a plurality of third through holes in the length direction of the third fixing plate 412.

[0045] Specifically, the longitudinal adjustment and angle compensation are realized through the array of the plurality of through holes on the second fixing plate 411 and the third fixing plate 412.

[0046] In some optional embodiments, the second through hole of the second fixing plate 411 extends in the length direction of the second fixing plate 411.
