Description

Technical Field

[0001] This application relates to the field of marine technology, and in particular to a platform and vessel with safety railings. Background Technology

[0002] The stairwells of chemical tankers and product tankers serve as important access routes for maintenance and observation. The deck surface is quite high above the bilge, and using a single platform without guardrails can easily cause fear among crew members. Improper operation could lead to a risk of falling from a height. To improve safety, unless otherwise specified, welded guardrails are added to the first-level platform, which are connected to the ladder or platform.

[0003] The stairwells of chemical tankers and product oil tankers serve as crucial access routes for maintenance and observation. Given the significant height of the deck above the bilge, using a single, unguarded platform can easily induce fear among crew members, and improper operation could lead to falls from heights. To improve safety, unless specifically required, welded guardrails are typically added to the first-level platform. These guardrails connect to the ladder or platform. The main problems with this type of guardrail include: 1. The guardrail connected to the elevator is lightweight and small in size, but it affects the passage of people and wastes platform space; 2. The guardrails connected to the platform do not affect the passage of people and make reasonable use of the platform space, but they are heavy and, without other support, are prone to damage to the platform. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a platform with safety railings. Based on the platform's own columns and railings, it is heightened upwards, providing ample operating space without obstructing personnel passage. The railings are welded to the upper deck and fastened to the platform, enhancing their stability. In special circumstances, the railings can be removed without damaging the platform's structure.

The platform body is equipped with a protective railing, which includes an upper handrail and a middle handrail. It is connected to the outside of the planar support frame by uprights. An entrance / exit is provided on one side of the platform body for connecting to an inclined ladder. A high guardrail is provided on the protective railing at one end of the planar support frame away from the support foot. It includes vertical bars and horizontal bars. The horizontal bars are provided on the upper handrail horizontal bars through the vertical bars. The top ends of at least two of the vertical bars are used to connect to the upper deck structure. A vertical ladder can be provided on the platform body corresponding to the high guardrail.

[0006] In some embodiments, the crossbar is disposed on the upper handrail crossbar via the vertical bar, including: The bottom of the vertical rod is clamped to the upper handrail crossbar via a clip-on connector.

[0007] In some embodiments, the vertical pole corresponds to the upright pole.

[0008] In some embodiments, the clip-on connector includes two opposing pressure plates, which are fastened together by bolts and nuts.

[0009] In some embodiments, the pressure plate is provided with a horizontal groove, a vertical groove is provided on one side of the horizontal groove, and a vertical opening is provided on the other side.

[0021] This invention provides a platform with safety railings. Based on the platform's own columns and railings, it is heightened upwards, providing ample operating space without obstructing personnel passage. The railings are welded to the upper deck and fastened to the platform, enhancing their stability. In special circumstances, the railings can be removed without damaging the platform's structure.

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] This invention provides a platform with safety railings, such as... Figure 1 As shown, it includes: The platform body 10 includes a platform pedal 11 and a support assembly 12. The support assembly 12 includes a planar support frame 13 and two diagonal supports 14.

[0024] The planar support frame 13 is a rectangular frame, and the platform step 11 is set on the planar support frame 13.

[0025] The planar support frame 13 has support feet 15 on both sides at one end for connecting to the bulkhead. Two diagonal supports 14 are connected at one end to the two sides of the bottom surface of the planar support frame 13 away from the support feet 15, and at the other end to the bulkhead. The diagonal supports 14 and the planar support frame 13, together with the bulkhead, form a triangular load-bearing structure. The triangular load-bearing structure has geometric stability and can effectively resist loads from multiple directions, preventing the platform body 10 from shaking or deforming when personnel walk or equipment is placed, significantly improving the overall structural rigidity and load-bearing safety of the platform.

[0026] The platform body 10 is equipped with a protective railing 20, which includes an upper handrail crossbar 21 and a middle crossbar 22, and is connected to the outside of the planar support frame 13 via uprights 23. An entrance 24 is provided on one side of the platform body 10, such as... Figure 2 As shown, it is used to connect the inclined ladder 51. The guardrail 20 is set around the platform body 10 to form a continuous safety protection boundary. The double-layer design of the upper handrail 21 and the middle handrail 22 provides reliable grip support for people of different heights, effectively reducing the risk of people falling. The opening of the entrance 24 ensures the continuity of the overall protection while providing a convenient passage for people to enter and exit the platform through the inclined ladder 51, taking into account both safety and passage efficiency.

[0027] A high guardrail 30, positioned around the end of the planar support frame 13 away from the support foot 15, is attached to the guardrail 20. It includes vertical bars 31 and horizontal bars 32. The horizontal bars 32 are connected to the upper handrail horizontal bar 21 via the vertical bars 31. The top ends of at least two vertical bars 31 are used to connect to the upper deck structure, such as... Figure 2 As shown, the vertical ladder 52 can be installed on the platform body 10 corresponding to the high guardrail 30. The high guardrail 30 further increases the protective height based on the guardrail 20, and is particularly suitable for the high-risk location of the area where the vertical ladder 52 is located. The top of the vertical bar 31 is connected to the upper deck structure to form a double-fixed support mode, making the high guardrail 30 a stable load-bearing component, effectively preventing people from accidentally falling from the top or side of the vertical ladder 52, and significantly improving the safety protection level of the area.

[0028] In some embodiments, the crossbar 32 is mounted on the upper handrail crossbar 21 via the vertical bar 31, such as... Figure 1 and Figure 3As shown, the vertical bar 31 is clamped to the upper handrail horizontal bar 21 at its bottom via a snap-fit ​​connector 40. The snap-fit ​​connector 40 secures the vertical bar 31 to the upper handrail horizontal bar 21 without requiring drilling or welding on the horizontal bar, thus avoiding damage to the original structural integrity of the guardrail 20. Installation only requires clamping and positioning, significantly simplifying the assembly process of the high guardrail 30 and improving on-site construction efficiency.

[0029] In some embodiments, the vertical bar 31 corresponds to the upright bar 23. The corresponding positions of the vertical bar 31 and the upright bar 23 enable the load transmitted by the high guardrail 30 to be directly transmitted to the planar support frame 13 in the vertical direction through the upright bar 23, thereby optimizing the force transmission path, reducing the additional bending moment generated on the guardrail system, and enhancing the overall structural performance.

[0030] In some embodiments, such as Figure 1 As shown, a pad 33 is provided at the top of the vertical rod 31, which connects to the upper deck structure. The pad 33 increases the contact area between the top of the vertical rod 31 and the upper deck structure, making the connection more stable and reliable. At the same time, it effectively disperses the concentrated stress at the top of the vertical rod 31, avoids local pressure damage to the deck structure, and extends the service life of the connection.

[0031] In some embodiments, the clip-on connector 40 includes two opposing pressure plates 41, which are fastened together by bolts 42 and nuts 43. The fastening method using two pressure plates 41 with bolts 42 and nuts 43 provides a secure connection with adjustable tightness, facilitating adaptive adjustments based on on-site installation errors. Furthermore, the bolted connection is highly standardized, easy to procure and replace, and reduces maintenance costs.

[0032] In some embodiments, such as Figure 4 As shown, the pressure plate 41 is provided with a horizontal groove 44, a vertical groove 45 is provided on one side of the horizontal groove 44, and a vertical opening 46 is provided on the other side. The horizontal groove 44 is used to cooperate with the upper handrail crossbar 21, the vertical groove 45 is used to cooperate with the bottom of the vertical bar 31, and the vertical opening 46 is used to cooperate with the top of the upright bar 23. The integrated design of the horizontal groove 44, the vertical groove 45, and the vertical opening 46 allows a single pressure plate 41 to simultaneously achieve three-way positioning cooperation with the upper handrail crossbar 21, the vertical bar 31, and the upright bar 23. During installation, the positions of each component are automatically aligned, reducing manual adjustment time. In addition, the groove structure provides mechanical limit to prevent slippage in the horizontal or vertical direction after connection, significantly improving connection accuracy and reliability.

[0033] In some embodiments, such as Figure 5As shown, the platform tread 11 has a grid structure. The grid structure of the platform tread 11 has a transparent mesh shape, which effectively reduces the overall weight of the platform and the load on the support components 12 while ensuring the load-bearing capacity of the tread. It also facilitates the timely discharge of liquids and debris, keeps the tread surface clean and dry, and reduces the risk of people slipping.

[0034] In some embodiments, such as Figure 5 and Figure 6 As shown, the grating structure includes multiple parallel, spaced square steel tubes 16, with one edge of each square steel tube 16 pointing vertically upwards. The arrangement of the square steel tubes 16 with their edges pointing vertically upwards creates a continuous raised anti-slip texture on the tread surface, increasing the friction between the shoe sole and the tread, maintaining good anti-slip performance even in wet or oily environments. Simultaneously, the cross-sectional shape of the square steel tubes 16 gives them a high flexural section modulus under load, resulting in good structural strength. The parallel, spaced arrangement facilitates standardized production and on-site assembly.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, a reinforcing connector 17 connects the diagonal support 14 and the planar support frame 13. The reinforcing connector 17 enhances the rigidity of the connection node between the diagonal support 14 and the planar support frame 13, making the force transmission of the triangular load-bearing structure smoother, avoiding deformation or damage at the node due to stress concentration, and further improving the structural stability and durability of the platform body 10 under dynamic loads.

[0036] In some embodiments, the safety railing platform of the present invention is used for the protection of the stairway from the oil tank cover to the first-level platform of the cargo hold. When this safety railing platform is applied to a specific stairway protection scenario from the oil tank cover to the first-level platform of the cargo hold, the arrangement of the high railing 30 with the inclined ladder 51 and vertical ladder 52 is mutually adapted, forming a complete safety protection system for this narrow stairway area. This not only meets the arrangement requirements within the limited space of the ship's cargo hold area but also ensures the safety of personnel moving up and down.

[0037] This invention provides a vessel equipped with a platform with safety railings as described in any of the above embodiments. By installing such a platform on the vessel, the stairwell area acquires standardized, detachable safety protection facilities, facilitating disassembly and maintenance according to inspection requirements during vessel operation, thereby improving the compliance and maintainability of the vessel's safety facilities.

[0038] The embodiments of the present invention employ a non-welded connection between the guardrail and the platform, facilitating disassembly without damaging the platform structure. The upper end connects to the deck surface, reducing the stress on the platform, providing ample operating space, and not obstructing passage. This enhances the stability of the guardrail, increases its operating space, and reduces platform stress through its connection to the deck. The bolted connection allows for disassembly without damaging the platform's structure.

[0039] The high guardrail 30 is connected to the upper deck structure via the top of the vertical bar 31, forming a support system that bears force from both ends simultaneously. This significantly improves the overall rigidity and anti-overturning capacity of the guardrail, effectively reducing the risk of deformation or collapse when personnel lean on it or when it is subjected to external impact, thus ensuring the safety of workers. The clip-on connector 40 uses a design with a pressure plate 41, horizontal grooves 44, vertical grooves 45, and vertical openings 46. This design eliminates the need for on-site welding or drilling when connecting the vertical bar 31 to the upper handrail horizontal bar 21 and upright bar 23, making installation and disassembly simple and quick, facilitating later maintenance and replacement, and avoiding damage to the structural performance of the platform body 10 caused by welding heat. The vertical bar 31 and upright bar 23 are correspondingly set, allowing the force on the high guardrail 30 to be directly transferred to the planar support frame 13 through the upright bar 23, optimizing the force transmission path and further enhancing the overall stability of the structure. The pad 33 increases the contact area between the top of the vertical bar 31 and the upper deck structure, making the connection more stable and reliable, while also dispersing local stress and preventing damage to the deck structure. The platform treads 11 adopt a grid structure, especially the square steel pipes 16 arranged with their edges pointing vertically upwards. This ensures the strength and load-bearing capacity of the treads while providing good anti-slip and drainage performance, and is also lightweight, which helps reduce the overall weight of the platform. A reinforcing connector 17 is provided between the diagonal support 14 and the planar support frame 13, further enhancing the stability of the triangular load-bearing structure and improving the platform's resistance to deformation under dynamic loads. The platform with safety railings of this invention is particularly suitable for ladder protection scenarios from the oil tank cover to the first-level platform of the cargo hold. The reasonable layout of the high railings 30, the diagonal ladders 51, and the vertical ladders 52 forms a complete safety protection system, satisfying both the convenience of personnel passage and ensuring the safety of operations in confined spaces.

[0040] The technical solutions described in the embodiments of this application can be combined arbitrarily without conflict.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
