Description

Technical Field

[0001] This utility model relates to the field of rail transit protection technology, and in particular to a railway steel railing with a safety net. Background Technology

[0002] With the rapid development of railway transportation, railways, as a vital transportation infrastructure, bear the ever-increasing transportation demands. The design of railway lines must not only ensure traffic safety but also guarantee their long-term operational stability and durability. Steel railings, as an important component of railway lines, directly relate to the railway's safety protection capabilities through their design and function. Traditional steel railing designs typically focus on structural stability but often neglect environmental factors, particularly the impact of changes in structural joints (such as bridge beam joints and roadbed joints) and temperature fluctuations along the railway line. Changes in railway structural joints are caused by various factors, especially in areas with large temperature differences, where railway foundation materials change due to thermal expansion and contraction, leading to displacement of structural joints.

[0003] Traditional fixed-structure steel railings fail to account for this change, resulting in an ineffective fit between the handrails and structural joints. When significant displacement occurs at the structural joints, the fixed-length steel pipe handrails cannot be adjusted, easily leading to deformation, cracks, or even breakage. This problem not only affects the railing's appearance and structural safety but also poses potential safety hazards to railway traffic. Furthermore, existing steel railings generally lack bottom safety protection measures, leaving unprotected areas between the railing and the railway foundation, creating safety hazards such as accidental falls of maintenance equipment and tools, trench covers, or slips and falls by maintenance personnel. While some existing designs attempt to address structural joint variations by adding adjustment devices or detachable connectors, these designs are typically highly complex, increasing the difficulty of construction and maintenance. Especially during long-term operation, the effects of structural joint displacement and temperature changes on connectors can lead to loosening, corrosion, or damage, reducing the railing's lifespan and stability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a railway steel railing with a safety net, which enables adaptive adjustment of the railing handrail when structural joints change. This effectively avoids deformation or breakage caused by structural joint displacement, thereby improving the durability and reliability of the steel railing and ensuring the overall safety of the railway line.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A railway steel railing with safety netting includes embedded steel plates, posts, and steel pipe handrails. The embedded steel plates are installed at pre-reserved installation positions on both sides of the railway line. The lower ends of the posts are installed on the embedded steel plates. Several steel pipe handrails are horizontally placed between adjacent posts. The steel pipe handrails are interrupted at corresponding positions of structural joints along the railway line and fitted with steel sleeves on their outer sides. The length of the steel sleeves is greater than the spacing of the structural joints. Both ends of the steel sleeves are connected to the steel pipe handrails, with one end using a bolt. The steel sleeve is fixed to the steel pipe handrail, with one end freely connected to the steel pipe handrail. The steel sleeve allows the steel pipe handrail to move relative to the handrail when the structural joint spacing changes. The safety net is located above the structural joint, with one side fixed to the connection between the column and the embedded steel plate and the steel pipe handrail by a fastener. The other side is movably disposed on a sliding groove at the connection between the adjacent column and the embedded steel plate and the steel pipe handrail. The sliding groove allows the safety net to move relative to the handrail when the structural joint spacing changes. The fastener and the sliding groove are detachable structures.

[0007] Preferably, the embedded steel plate is fixedly connected to the railway foundation by U-bolts. The bottom of the U-bolt is embedded in the railway foundation, and both ends of the U-bolt extend out of the surface of the railway foundation. Through holes are provided on the embedded steel plate, and the through holes are fitted onto the ends of the U-bolt and locked with screws.

[0008] Preferably, each of the pre-embedded steel plates is provided with two U-bolts, located on both sides of the column.

[0009] Preferably, the steel pipe handrail includes a top steel pipe handrail and multiple lower steel pipe handrails.

[0010] Preferably, the top steel pipe handrail is made of φ60 steel pipe, and the corresponding top steel sleeve is φ70 steel sleeve; the lower steel pipe handrail is made of φ34 steel pipe, and the corresponding lower steel sleeve is φ42 steel sleeve; and the bolts are M8 bolts.

[0011] Preferably, the spacing between the columns is 2 meters.

[0012] Preferably, the two ends of the steel sleeve are fixed with a closing ring, the closing ring including a ring body and a brush part, the brush part abutting against the steel pipe handrail through the bristles to prevent dust from entering the steel sleeve.

[0013] Preferably, the steel pipe handrail is provided with end caps at both ends.

[0014] Preferably, the embedded steel plate, column, steel pipe handrail and steel sleeve are all made of composite stainless steel.

[0015] Preferably, the steel pipe handrail and the upright are of the same color.

[0016] Compared with existing technologies, the advantages of this utility model are as follows: The railway steel railing with safety net, through the combination design of steel sleeves and steel pipe handrails, can adapt to the expansion and contraction deformation of the structural joints along the line due to temperature changes, avoiding the stress concentration, breakage, or deformation problems caused by thermal expansion and contraction of traditional continuous handrails, thus significantly improving the safety and service life of the railing. The pre-embedded steel plates are fixed to the railway foundation with U-bolts, and the U-bolts are pre-embedded inside the railway foundation, significantly enhancing the stability and bending resistance of the overall structure, effectively resisting high-frequency vibrations and external load impacts along the railway line. The closed rings at both ends of the steel sleeves are tightly fitted to the steel pipe handrails using brushes, preventing dust and rainwater from entering the sleeve, preventing sliding parts from failing due to impurities, and reducing maintenance costs. Furthermore, the steel pipe handrails use standardized dimensions and matching steel sleeves, combined with standard post spacing, enabling factory prefabrication and rapid on-site installation, reducing construction complexity and material waste, and balancing economy and reliability. The safety net uses steel wire mesh material, which can effectively prevent people or objects from falling, enhancing the safety of the railing. The safety net, in conjunction with the sliding groove, can move accordingly as the spacing of the structural joints changes, maintaining a stable protective effect. This enhances the adaptability and flexibility of the railing system, further improving the overall structural safety and economy. Simultaneously, the connection between the safety net and the posts and steel pipe handrails is detachable, allowing for easy removal when not needed, reducing the complexity of maintenance and replacement.

[0022] 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 belong to the present utility model.

[0023] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0024] like Figure 1-3 As shown, this embodiment discloses a railway steel railing with a safety net, including a pre-embedded steel plate 1, posts 2, and steel pipe handrails 3. The pre-embedded steel plate 1 is installed at pre-reserved installation positions on both sides of the railway line. The lower end of the post 2 is installed on the pre-embedded steel plate 1, and several steel pipe handrails 3 are horizontally placed between adjacent posts 2. The steel pipe handrails 3 are broken at the corresponding positions of the structural joints 5 along the railway line, and steel sleeves 4 are fitted on the outer side. The length of the steel sleeves 4 is greater than the spacing of the structural joints 5. When the structural joints 5 are displaced, the steel sleeves 4 can provide sufficient length to ensure the fit between the steel pipe handrails 3 and the structural joints 5. Both ends of the steel sleeve 4 are connected to the steel pipe handrail 3. One end is fixed to the steel pipe handrail 3 by bolts 6, while the other end is freely connected to the steel pipe handrail 3. This ensures a certain degree of freedom for the steel pipe handrail 3 when the structural joint 5 shifts, avoiding constraint stress between the steel pipe handrail 3 and the steel sleeve 4. The steel sleeve 4 allows the steel pipe handrail 3 to move relative to the structural joint spacing when it changes, ensuring that the steel pipe handrail 3 can adapt to changes in the structural joint, thereby avoiding excessive stress concentration and preventing deformation or breakage of the steel railing due to changes in the structural joint. Through this design, even when the structural joint along the railway line shifts due to temperature differences or structural changes, the railing can still maintain stability, ensuring the safety and durability of the railing structure. At the end of the foundation of a curved railway, to further ensure the free expansion and contraction of the steel pipe handrail 3, the steel sleeve 4 can be appropriately bent to adapt to the curved shape along the railway line, while reducing rigid constraints and improving the adaptability and stability of the overall railing structure.

[0025] like Figure 1As shown, safety net 10 is installed above structural joint 5. Safety net 10 can be made of wire mesh to seal the bottom of the steel railing, preventing objects or people from falling. One side of safety net 10 is fixed to the connection between the post 2 and the embedded steel plate 1 and steel pipe handrail 3 via fastener 11, ensuring the stability of the safety net. The other side is movably installed on a sliding groove 12 at the connection between the adjacent post 2 and the embedded steel plate 1 and steel pipe handrail 3. The sliding groove 12 is located at two corners on the other side of the rectangular safety net 10. The sliding groove 12 allows the safety net 10 to move relative to the structural joint 5 as the spacing changes, thus adapting to changes in the spacing of the structural joint 5 and ensuring that the safety net 10 always remains in a suitable position. Both the fastener 11 and the sliding groove 12 are detachable structures, allowing for flexible configuration of the fastener 11, sliding groove 12, and safety net 10 according to actual needs. If the safety net 10 is not required, the fastener 11 and sliding groove 12 can be removed, thus avoiding unnecessary costs and structural complexity.

[0026] Furthermore, the embedded steel plate 1 is fixedly connected to the railway foundation 8 by U-bolts 7. The bottom of the U-bolt 7 is embedded in the railway foundation 8, and both ends of the U-bolt 7 extend out of the surface of the railway foundation 8. Through holes are provided on the embedded steel plate 1, and the through holes are fitted onto the ends of the U-bolt 7 and locked with screws. This structure ensures that the embedded steel plate 1 is firmly connected to the railway foundation 8. The overall stability of the steel railing and the railway foundation 8 is enhanced by the cooperation of the U-bolts 7 and screws. Two U-bolts 7 are provided in each embedded steel plate 1 and are located on both sides of the column 2. This arrangement allows the column 2 to be more firmly fixed to the embedded steel plate 1, and also ensures a more secure connection between the column 2 and the railway foundation 8, thereby improving the load-bearing capacity of the steel railing.

[0027] In some embodiments, the steel pipe handrail 3 includes a top steel pipe handrail and multiple lower steel pipe handrails. The top steel pipe handrail uses φ60 steel pipes, and the corresponding top steel sleeve is a φ70 steel sleeve. The lower steel pipe handrails use φ34 steel pipes, and the corresponding lower steel sleeve is a φ42 steel sleeve. The bolts 6 are M8 bolts. This design of steel pipe handrails and steel sleeves of different sizes ensures that the steel pipe handrail 3 maintains good structural strength under various load conditions and can adapt to changes in the structural joints 5. The bolts 6 are used to fix the steel pipe handrail 3 and the steel sleeves 4, ensuring the stability of the steel pipe handrail 3. The spacing of the posts 2 is 2 meters. This spacing design takes into account the load-bearing requirements of the railway line structure and the steel railing, providing sufficient support and ensuring the stability of the railing.

[0028] In addition, both ends of the steel sleeve 4 are fixed with sealing rings 9, which include a ring body and a brush part. The brush part abuts against the steel pipe handrail 3 through its bristles, preventing dust from entering the steel sleeve 4 and ensuring that the relative movement between the steel pipe handrail 3 and the steel sleeve 4 is unimpeded, avoiding jamming problems caused by dust accumulation. The design of the sealing ring 9 not only ensures the sealing of the steel sleeve 4, but also prevents dust accumulation inside the steel sleeve 4, thereby reducing maintenance requirements and extending the service life of the steel railing. End caps are provided at both ends of the steel pipe handrail 3. The purpose of the end caps is to prevent rainwater from entering the steel pipe handrail 3, avoiding rainwater seepage and affecting the stability of the structure.

[0029] In this utility model, the steel railing posts 2 are connected to the embedded steel plates 1 and steel pipe handrails 3 using manual arc welding to ensure strong welds and improve the stability and durability of the overall structure. Simultaneously, to enhance the railing's corrosion resistance, all steel structural components, including the embedded steel plates 1, posts 2, steel pipe handrails 3, and steel sleeves 4, are made of composite stainless steel to meet the needs of long-term exposure to the outdoor environment along the railway line. To maintain the overall aesthetic appeal of the railing, it is recommended that the steel pipe handrails 3 and posts 2 use the same color, preferably "Ice Gray" color 77 / GY09 from the "Paint Film Color Standard Sample Card (GSB05-1426-2001)," to ensure the railing coordinates with the railway structure and creates a simple and elegant visual effect. The standard spacing of the railing posts 2 is set at 2.0m, but the end positions can be adjusted appropriately according to actual conditions to adapt to the specific layout of the railway structure. When arranging the posts 2, care should be taken to ensure that the spacing between the posts 2 at the ends is not too small, so as to ensure that the posts 2 are evenly distributed along the entire railway line, which not only meets the requirements of structural stability, but also ensures the aesthetic harmony of the overall appearance.

[0030] In summary, this utility model discloses a railway steel railing with a safety net. By employing a fixing method combining a pre-embedded steel plate 1 and U-bolts 7, the steel railing is securely installed along the railway line. The cooperative design of the steel pipe handrail 3 and the steel sleeve 4 not only allows the steel pipe handrail 3 to move relative to the structural joint 5 when changes occur, avoiding excessive stress concentration caused by structural joint variations, but also ensures the stability of the steel railing. In particular, the brush sections 9 at both ends of the steel sleeve 4, with bristles abutting against the steel pipe handrail 3, effectively prevent dust from entering the steel sleeve 4, avoiding jamming problems, while not affecting the relative movement between the steel sleeve 4 and the steel pipe handrail 3. The design of this utility model fully considers the challenges faced by railway steel railings in actual use, especially the problem of displacement of structural joints due to temperature differences or structural changes. Through the innovative combination of the steel pipe handrail 3, steel sleeve 4, and closing ring 9, the problem of traditional railing designs being unable to adapt to structural joint changes is solved, significantly improving the adaptability and stability of the steel railing, while reducing long-term maintenance costs. This technology not only has significant application value in actual railway engineering projects, but also provides the industry with a safer, more reliable, and durable solution. This technical solution is of great importance to the safety, stability, and service life of railway engineering. Its innovative design not only improves the performance of steel railings under complex environmental conditions, but also provides new ideas for the maintenance and management of railway lines, possessing broad prospects for industry promotion and economic benefits.
