[0001] The present invention relates to the technical field of ship fittings, and particularly to a bulwark handrail for the two-wing bulwarks of a cab. Background Art

[0002] During the shipbuilding and operation processes, the installation of handrails on the two-wing bulwarks of the navigating deck of a bulk carrier and the bulwarks of a Panama platform is of crucial importance. However, the current bulwark handrails face a series of problems. Due to the diversity of shipowner requirements and design styles, the handrail types are various and lack a unified standard. The common design of using φ42.4×3.5 galvanized welded steel pipes with RB20 round steel supports and backing plates not only consumes a large amount of materials, increases costs, but also has a huge welding workload during production, resulting in low production efficiency. In addition, traditional vertical supports are prone to catching hands, and it is inconvenient for crew members to grip them when the ship is bumping and swaying, posing a safety hazard. At the same time, in the humid ship navigation environment, the anti-slip and anti-corrosion performance of the handrails is poor, affecting the service life and safety of use. Summary of the Invention

Reserved installation components are arranged on the handrail and the bent connection segment. A cleaning component is slidably arranged on the handrail, and there are two cleaning components.

[0005] Further, the buffer base includes a hollow round seat. A connecting plate is fixedly installed on the outer wall of the hollow round seat. Installation holes are opened on the connecting plate. A through hole is opened at the top of the hollow round seat. The bottom end of the bent connection segment extends into the hollow round seat from the through hole. The inner diameter of the through hole is larger than the outer diameter of the bent connection segment. Upper and lower limit rings are fixedly sleeved on the outer wall of the bent connection segment. The outer diameters of the upper and lower limit rings are larger than the inner diameter of the through hole. The upper limit ring is located outside the hollow round seat, and the lower limit ring is located inside the hollow round seat. A buffer structure is installed inside the hollow round seat. There are six buffer structures, and they are circumferentially and arrayedly distributed around the bottom end of the bent connection segment.

[0006] Further, the buffer structure includes a curved surface push block, a telescopic rod, and a spring.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Embodiment 1 Please refer to Figures 1 - 8The present invention provides a technical solution: a bulwark handrail for the bulwarks of both wings of a cab, comprising a handrail 1, two ends of the handrail 1 are provided with an integrally formed curved connecting section 2, the bottom end of the curved connecting section 2 is connected with a buffer base 3, the handrail 1 and the curved connecting section 2 are provided with a reserved installation component 4, a cleaning component 5 is slidably provided on the handrail 1, and two cleaning components 5 are provided. The integrally formed handrail 1 and the curved connecting section 2 are provided to reduce the position required for welding during on-site construction, thereby reducing the difficulty of on-site work, and the curved connecting section 2 can avoid the problem of hand jamming relative to the directly connected right-angle section, and the buffer base 3 is provided for buffering. When the ship encounters severe shaking or turbulence, the impact force generated by the crew grasping the handrail 1 will be absorbed by the buffer base 3, avoiding excessive buffering. The handrail shakes too much, and the stability of the crew's grip is guaranteed. This design effectively reduces the damage to the crew caused by the shaking of the hull, and improves the safety of the handrail under extreme navigation conditions. A reserved installation component 4 is set for installing LED lighting, monitoring sensors, etc. Different functional modules can be inserted according to actual needs, such as an emergency call button module, an environmental monitoring sensor module (for monitoring temperature, humidity, and harmful gas concentrations). These modules can be connected to the ship's central control system through a built-in ship communication module to achieve data sharing and remote control, and provide support for the intelligent management of the ship. During the navigation of the ship, dust, salt, oil and other pollutants are easily attached to the surface of the handrail 1, affecting the appearance and performance. A cleaning component 5 is set to clean the handrail 1; The buffer base 3 includes a hollow round seat 301, a connecting plate 302 is fixedly installed on the outer wall of the hollow round seat 301, a mounting hole is provided on the connecting plate 302, a through hole 305 is provided on the top of the hollow round seat 301, the bottom end of the curved connecting section 2 extends into the hollow round seat 301 from the through hole 305, the inner diameter of the through hole 305 is larger than the outer diameter of the curved connecting section 2, an upper limit ring 303 and a lower limit ring 304 are fixedly sleeved on the outer wall of the curved connecting section 2, the outer diameters of the upper limit ring 303 and the lower limit ring 304 are larger than the inner diameter of the through hole 305, the upper limit ring 303 is located outside the hollow round seat 301, the lower limit ring 304 is located inside the hollow round seat 301, and a buffer structure 30 is installed inside the hollow round seat 301 6. Six buffer structures 306 are provided and are distributed in an array around the bottom end of the curved connection section 2. A connecting plate 302 is provided to fix the hollow round seat 301 to the bulwark. An upper limit ring 303 and a lower limit ring 304 are provided to connect the curved connection section 2 to the hollow round seat 301, so that the bottom end of the curved connection section 2 cannot be separated from the hollow round seat 301. The curved connection section 2 is buffered by the buffer structure 306, and the six buffer structures 306 can buffer the curved connection section 2 from multiple angles to ensure the buffer effect. Because the inner diameter of the through hole 305 is larger than the outer diameter of the curved connection section 2, the curved connection section 2 can be moved under force, and then the buffer structure 306 is triggered to buffer the impact. The buffer structure 306 includes a curved surface push block 3061, a telescopic rod 3062, and a spring 3063. One end of the telescopic rod 3062 is fixedly connected to the outer wall of the curved surface push block 3061, and the other end is fixedly connected to the inner wall of the hollow circular seat 301. The curved surface on the curved surface push block 3061 abuts against the outer wall of the bent connecting section 2. One end of the spring 3063 is fixedly connected to the outer wall of the curved surface push block 3061, and the other end is fixedly connected to the inner wall of the hollow circular seat 301. Among them, the spring 3063 serves as an elastic buffer to buffer the impact. The telescopic rod 3062 is provided to support and install the curved surface push block 3061, so that when the bent connecting section 2 is forced to move, it can push the curved surface push block 3061 to move. However, because the curved surface on the curved surface push block 3061 contacts the bent connecting section 2, when the bent connecting section 2 moves relative to the curved surface push block 3061, the friction force received is smaller, thereby reducing the wear rate of the curved surface push block 3061; The reserved installation component 4 includes a wire inlet / outlet 401 and an installation groove 402. The wire inlet / outlet 401 is opened on the bent connecting section 2, and the installation groove 402 is opened on the armrest 1. And the inside of the installation groove 402 is communicated with the inside of the armrest 1. The wire inlet / outlet 401 is communicated with the inside of the bent connecting section 2. An elastic clamping plate 403 is fixedly installed in the installation groove 402. The installation groove 402 is provided for installing electronic devices such as LED lighting lamps and monitoring sensors. The wire is led into the bent connecting section 2 and the armrest 1 through the wire inlet / outlet 401, so that the electronic devices installed in the installation groove 402 can be connected to the wire. The elastic clamping plate 403 is provided to clamp the electronic devices installed in the installation groove 402, so that when installing the electronic devices, the elastic clamping plate 403 can be used to first clamp the electronic devices, and then screws can be used to fix the electronic devices, which can effectively avoid the problem of the electronic devices shifting under force during installation; There are two groups of installation grooves 402. One group of installation grooves 402 is located on the front of the armrest 1, and the other group is located on the back of the installation groove 402. More installation grooves 402 are used to install more electronic devices, and the two groups of installation grooves 402 provided on the front and back of the armrest 1 can be used to install LED lighting lamps with different orientations; A transparent card board 6 is clamped in the installation groove 402. Both sides of the transparent card board 6 are provided with protrusions, and the protrusions are clamped into the gap between the elastic clamping plate 403 and the inner wall of the installation groove 402. Whether there are electronic devices installed in the installation groove 402 or not, the transparent card board 6 can be clamped into the installation groove 402 to protect the inside of the installation groove 402, which can effectively avoid rainwater, seawater, etc. from entering the installation groove 402. And the protrusions on both sides of the transparent card board 6 are clamped into the gap between the elastic clamping plate 403 and the inner wall of the installation groove 402, and the elasticity of the elastic clamping plate 403 can be used to reinforce the transparent card board 6, which can effectively avoid the transparent card board 6 falling off during the shaking of the ship; A buffer ring 8 is fixedly installed on the inner wall of the through hole 305. The inner diameter of the buffer ring 8 is larger than the diameter of the curved connecting section 2. When the curved connecting section 2 moves relative to the hollow round seat 301, the curved connecting section 2 is easy to collide with the inner wall of the through hole 305, and then collide with the rigid inner wall of the through hole 305, thereby making a loud noise. The buffer ring 8 can avoid the collision between the curved connecting section 2 and the inner wall of the through hole 305, thereby avoiding the emission of a loud noise. A ball 9 is provided at the bottom end of the curved connecting section 2. The ball 9 presses on the bottom inner wall of the hollow round seat 301 to avoid direct contact between the bottom of the curved connecting section 2 and the inner wall of the hollow round seat 301, thereby preventing the curved connecting section 2 from being in direct contact with the inner wall of the hollow round seat 301, thereby causing obvious wear between the curved connecting section 2 and the inner wall of the hollow round seat 301 when the curved connecting section 2 moves relative to the hollow round seat 301. A mounting groove is provided at the bottom of the hollow round seat 301, and an elastic washer 7 is fixedly installed in the mounting groove. The elastic washer 7 protrudes from the mounting groove. The elastic washer 7 is provided to increase the friction between the bulwark and the hollow round seat 301. During installation, the elastic washer 7 can be pressed and deformed, so that the friction between the hollow round seat 301 and the bulwark becomes larger, so that the hollow round seat 301 will not slide relative to the bulwark.

[0019] Working principle: when in use, align the two hollow round seats 301 with the positions to be installed, then put them down, first weld the fixing bolts at the positions where the connecting plate 302 is aligned, and then use nuts to fix the connecting plate 302, so as to complete the installation of the bulwark handrail. When the ship encounters severe shaking or turbulence, the impact force generated by the crew grasping the handrail 1 will be transmitted to the curved connecting section 2, so that the curved connecting section 2 finds relative movement. At this time, the curved connecting section 2 will push one or two curved surface push blocks 3061 to move, and then squeeze the spring 3063, and use the spring 3063 to buffer the impact force. After installing the bulwark handrail, the wire can be inserted from the wire inlet and outlet 401, and the transparent card plate 6 can be lifted up with a tool, and then the transparent card plate 6 can be removed, and the LED lighting or monitoring sensor can be installed in the installation groove 402, and then the transparent card plate 6 can be inserted. These electronic devices can be connected to the central control system of the ship through the built-in ship communication module to realize data sharing and remote control, so as to provide support for the intelligent management of the ship.
