Description

Technical Field

[0001] This utility model relates to the field of railway column support technology, specifically a railway rigid crossbeam hanging column. Background Technology

[0002] In many engineering fields, corrosion prevention of metal structures has always been a major concern. During use, metal components are highly susceptible to corrosion due to environmental factors such as humid air and chemical media. This not only reduces the strength and service life of the metal structure but may also lead to safety hazards.

[0003] In practical applications, corrosion in the bolt-fastening area is a particularly prominent problem. During bolt tightening, the paint surface is easily damaged, exposing the metal substrate to the environment. When different metals or metals come into contact with electrolytes, a galvanic cell effect is formed, accelerating metal corrosion. Furthermore, existing protective measures are insufficient to effectively protect the bolt-fastening area, and subsequent inspection and maintenance are inconvenient. Additionally, in scenarios requiring components to be fixed to circular steel pipes, ordinary fixing methods cannot meet the fit requirements of the circular surface, resulting in insecure fixing and affecting the overall structural stability and safety. Therefore, this application provides a railway rigid crossbeam suspension column. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a railway rigid crossbeam suspension column, which solves the problem that existing technologies are prone to paint damage when tightening bolts, exposing the metal substrate, forming a galvanic effect that accelerates corrosion, and existing protective measures are ineffective in protecting this area.

[0005] The railway rigid crossbeam hanging column of this utility model includes a column for support, a connecting plate is provided on the top of the column, a support column is fixedly connected to the top of the connecting plate, and two symmetrically arranged angle steels are provided on the top of the support column. A fixing clamp is provided on the top of the angle steels for fixing the steel pipe frame. The fixing clamp includes a clamping plate, and the bottom of the clamping plate and the top of the angle steel are symmetrically provided with arc-shaped areas. The arc-shaped areas are adapted to the steel pipe frame, and arc-shaped pads are provided at the arc-shaped areas to support the bottom of the steel pipe frame. Both ends of the top of the clamping plate and the top of the angle steel have through holes and are equipped with locking devices to fix the steel pipe frame.

[0006] As a further improvement of this utility model, the locking component includes a screw, a nut, and a protective component. The protective component is sleeved on the shank of the screw, and one side of the protective component is in contact with the top of the clamping plate.

[0007] As a further improvement of this utility model, the nut is sleeved on the outside of the screw and located at the bottom of the angle steel. A protective plate is also provided between the top of the nut and the bottom of the angle steel to protect the paint surface at the bottom of the angle steel.

[0008] As a further improvement of this utility model, the protective component includes a gasket, there are at least two gaskets arranged symmetrically, and a combined area is formed between the two gaskets. One side of one of the combined areas is provided with a filling port arranged in a ring array, and an insertion groove is provided on the outer side of the filling port.

[0009] As a further improvement of this utility model, a squeezing block is provided at another combined area corresponding to the filling port, and the squeezing block is used to squeeze the inside of the filling port.

[0010] As a further improvement of this utility model, the outer side of the extrusion block is provided with a flange, which is adapted to the insertion groove for positioning the two combined areas.

[0011] As a further improvement of this utility model, the gasket has a plug-in interface in the middle, which is adapted to the screw and used to position the screw.

[0012] As a further improvement of this utility model, the column includes a column body, and a reinforcing block is provided on the outer side of the column body at the bottom of the connecting plate for reinforcing the connecting plate.

[0013] As a further improvement of this utility model, baffles are provided at both ends of the two angle steels, and the two baffles form a protective area to prevent birds from entering.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides reliable protection for bolt fastening areas by setting a compression washer in the bolt fastening area. When the bolt is tightened, the washer releases protective coating and forms a protective film in the bolt fastening area. This effectively prevents the problem of accelerated corrosion caused by the galvanic effect formed by paint damage, and provides reliable protection for the bolt fastening area. The protective gaskets and protective plates are designed for easy replacement. During later maintenance, they can be easily replaced simply by loosening the bolts, which greatly reduces maintenance difficulty and cost and improves maintenance efficiency. The arc-shaped area and arc-shaped pad design on the fixing clamp can be well adapted to the circular steel pipe frame and fit tightly against the surface of the steel pipe frame, realizing the firm fixation of special-shaped components and ensuring the stability and safety of the entire railway rigid crossbeam suspension column system.

[0017] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0018] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0019] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 When bolts are tightened, the paint surface is easily damaged, exposing the metal substrate and forming a galvanic cell effect that accelerates corrosion. Existing protective measures are difficult to effectively protect this area, which is not conducive to later replacement and maintenance, and increases the difficulty and cost of maintenance.

[0020] Ordinary fixing methods are difficult to meet the fitting requirements of special-shaped components such as round steel pipes, resulting in unstable fixing and affecting structural stability and safety. Based on this, this application provides a railway rigid crossbeam hanging column, including a column 4 for support, a connecting plate 5 on the top of the column 4, a support column 3 fixedly connected to the top of the connecting plate 5, two symmetrically arranged angle steels 7 on the top of the support column 3, and a fixing clamp 2 on the top of the angle steels 7 for fixing the steel pipe frame 1. The fixing clamp 2 includes a clamping plate 21. The bottom of the clamping plate 21 and the top of the angle steel 7 are symmetrically provided with arc-shaped areas. The arc-shaped areas are adapted to the steel pipe frame 1. Arc-shaped pads 22 are provided in the arc-shaped areas to support the bottom of the steel pipe frame 1. Both ends of the top of the clamping plate 21 and the top of the angle steel 7 are provided with through holes and are equipped with locking parts 6, which are used to fix the steel pipe frame 1.

[0021] In railway construction, the railway rigid beam suspension column plays a crucial role in supporting the steel pipe frame 1 above the railway. The railway rigid beam suspension column involved in this embodiment mainly includes a support column 4, which is rooted in the ground or a railway-specific foundation structure, providing stable support for the entire suspension column system. A connecting plate 5 is provided at the top of the column 4, tightly connecting the column 4 to the supporting column 3 above, ensuring effective force transmission. Two symmetrically arranged angle steels 7 are provided at the top of the supporting column 3. The angle steels 7 have good structural strength and stability, providing a reliable foundation for the subsequent fixing of the steel pipe frame 1. A fixing clamp 2 is provided at the top of the angle steels 7, which firmly fixes the steel pipe frame 1, ensuring its stability under various environmental conditions.

[0022] The column 4 is made of high-strength steel and is cylindrical in shape, which can evenly bear the pressure from above and the force of lateral wind. The bottom of the column 4 is specially treated with an anti-corrosion coating to prevent corrosion in moist soil environments. Additionally, reinforcing ribs can be added to the bottom of the column 4 to further enhance its stability. The connecting plate 5 is a square steel plate of moderate thickness, ensuring sufficient strength without being excessively heavy. The connecting plate 5 is securely connected to the top of the column 4 by welding. The support column 3 is also made of steel, and its shape is a square column 41. This shape allows for better connection and fit with the connecting plate 5 and the angle steel 7. The top of the support column 3 is connected to two symmetrically arranged angle steels 7 by bolts. The specifications and strength of the bolts have been precisely calculated and selected to ensure the firmness of the connection. The angle steel 7 is an equilateral angle steel, made of high-strength alloy steel, which has high strength and toughness. The surface of the angle steel 7 has undergone multi-metal co-infiltration anti-corrosion treatment, forming an alloy infiltration layer with good corrosion resistance, which can effectively resist the erosion of environmental factors such as humid air and rainwater, and extend the service life of the angle steel 7.

[0023] The fixing clamp 2 mainly consists of a clamping plate 21 and an arc-shaped pad 22. The clamping plate 21 is a steel plate with symmetrical arc-shaped areas on its bottom and the top of the angle steel 7. The curvature of these arc-shaped areas perfectly matches the outer diameter of the steel pipe frame 1, allowing it to fit tightly against the surface of the steel pipe frame 1. Arc-shaped pads 22, made of elastic materials such as rubber, are placed in these arc-shaped areas. These pads support the bottom of the steel pipe frame 1 and also act as buffers and shock absorbers, reducing vibration and wear when the steel pipe frame 1 is subjected to external forces. Through holes are provided at both ends of the top of the clamping plate 21 and the top of the angle steel 7 to ensure accurate installation of the locking element 6. The locking element 6 uses high-strength bolts and nuts 61. After the bolts pass through the through holes, tightening the nuts 61 tightly connects the clamping plate 21 and the angle steel 7, thus achieving a secure fixation of the steel pipe frame 1. The heads of the bolts and the surfaces of the nuts 61 are also treated with anti-corrosion coatings to prevent corrosion during long-term use and to ensure effective fixing.

[0024] In the bolt-tightening area, a special compression gasket 631 is used to prevent corrosion caused by the galvanic effect resulting from paint damage. This compression gasket 631 contains a protective coating. When the bolts are tightened, the gasket 631 is compressed, releasing the internal protective coating and forming a protective film in the bolt-tightening area. This effectively prevents the metal substrate from being exposed to the environment, reducing corrosion. Furthermore, the gasket 631 is very easy to replace. During later maintenance, simply loosening the bolts allows for easy replacement, significantly reducing maintenance difficulty and cost. Simultaneously, the arc-shaped design on the fixing clamp 2 effectively meets the fixing requirements with the circular steel pipe frame 1, ensuring that the steel pipe frame 1 does not shake or shift during fixing, thus guaranteeing the stability and safety of the entire railway rigid crossbeam suspension system.

[0025] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 The locking component 6 includes a screw 62, a nut 61, and a protective component 63. The protective component 63 is sleeved on the shaft of the screw 62, and one side of the protective component 63 is in contact with the top of the clamping plate 21.

[0026] Nut 61 is sleeved on the outside of screw 62 and located at the bottom of angle steel 7. A protective plate is also provided between the top of nut 61 and the bottom of angle steel 7 to protect the paint surface at the bottom of angle steel 7.

[0027] The protective component 63 includes a gasket 631. There are at least two gaskets 631 arranged symmetrically. A combined area 632 is formed between the two gaskets 631. A filling port 634 is arranged in a ring array on one side of one of the combined areas 632. A insertion groove 635 is provided on the outside of the filling port 634.

[0028] Another combination area 632 is provided with a squeezing block 636 corresponding to the filling port 634. The squeezing block 636 is used to squeeze the inside of the filling port 634.

[0029] The outer side of the extrusion block 636 is provided with a flange 637, which is adapted to the insertion groove 635 and is used for positioning the two combined areas 632.

[0030] The spacer 631 has a insertion interface 633 in the middle, which is adapted to the screw 62 and is used to position the screw 62.

[0031] The locking component 6 mainly consists of a screw 62, a nut 61, and a protective component 63. The nut 61 cooperates with the screw 62. By tightening the nut 61, the clamping plate 21 and the angle steel 7 can tightly clamp the steel pipe frame 1, ensuring that the steel pipe frame 1 will not loosen under various external forces. The protective component 63 is designed to prevent damage to the paint surface of the contact points between the screw 62, nut 61, clamping plate 21, and angle steel 7 during the locking process and subsequent use, thereby avoiding corrosion problems caused by the galvanic effect formed by paint damage.

[0032] A protective element 63 is fitted onto the shaft of the screw 62, with one side of the protective element 63 fitting snugly against the top of the clamping plate 21. The screw 62 is made of high-strength alloy steel, and its surface has undergone fine machining treatment, resulting in high smoothness and precision to ensure a good fit with the nut 61. The protective element 63, fitted onto the screw 62, effectively isolates the screw 62 from direct contact with the clamping plate 21, reducing potential damage to the paint surface of the clamping plate 21 caused by friction and wear during tightening.

[0033] Nut 61 is fitted onto the outside of screw 62 and located at the bottom of angle steel 7. Nut 61 is also made of high-strength alloy steel, and its threads precisely match the threads of screw 62 to ensure sufficient tightening force. A protective plate is provided between the top of nut 61 and the bottom of angle steel 7. The protective plate is usually made of rubber or plastic with a certain degree of elasticity and corrosion resistance. When nut 61 is tightened, the protective plate is compressed and fills the gap between nut 61 and the bottom of angle steel 7. This not only acts as a buffer, reducing the direct pressure of nut 61 on the painted surface of the bottom of angle steel 7, but also forms a sealing layer to prevent the ingress of corrosive media such as moisture and dust, thus effectively protecting the painted surface of the bottom of angle steel 7.

[0034] The protective component 63 includes at least two symmetrically arranged gaskets 631. These gaskets 631 are made of a material with a certain degree of elasticity and corrosion resistance, such as a rubber-plastic composite material. A combination area 632 is formed between the two gaskets 631. This combination design allows the protective component 63 to better adapt to the shape and size of the screw 62 and facilitates installation and removal.

[0035] One side of one of the assembly areas 632 has a ring-shaped array of filling ports 634, and an insertion groove 635 is provided on the outer side of the filling ports 634. The filling ports 634 are designed to accommodate protective coatings, which can be paints or other protective agents with good anti-corrosion properties. The insertion groove 635 is provided for positioning and mating with a structure on another gasket 631.

[0036] Another assembly area 632, corresponding to the filling port 634, is equipped with a compression block 636. The compression block 636 is used to compress the inside of the filling port 634. When the two gaskets 631 are assembled together and fitted onto the screw 62 and the nut 61 is tightened, the compression block 636 gradually moves towards the filling port 634 and compresses it. As the compression proceeds, the protective coating inside the filling port 634 is squeezed out and applied to the contact area between the screw 62 and the clamping plate 21 and the angle steel 7, forming a protective film and further enhancing the anti-corrosion effect.

[0037] The extrusion block 636 has a flange 637 on its outer side, which is adapted to the insertion groove 635 for positioning the two combined areas 632. The precise fit between the flange 637 and the insertion groove 635 ensures that the two gaskets 631 are accurately positioned during assembly, allowing the extrusion block 636 to be accurately aligned with the filling port 634, ensuring that the protective coating can be extruded smoothly and evenly.

[0038] The gasket 631 has a connector 633 in the middle, which is adapted to the screw 62 for positioning the screw 62. The size and shape of the connector 633 are precisely designed to fit tightly onto the screw 62, ensuring that the protective part 63 is stably positioned on the screw 62 and will not shift during use, thereby ensuring the stability and reliability of the protective effect.

[0039] The locking component 6 not only achieves a firm fastening effect, but also effectively prevents corrosion caused by paint damage. The protective component 63 and the protective plate provide all-round protection for the contact parts of the screw 62, nut 61 with the clamp 21 and angle steel 7, which greatly extends the service life of the entire structure, reduces the workload and cost of later maintenance, and improves the safety and reliability of railway facilities.

[0040] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The column 4 includes a column body 41, and a reinforcing block 42 is provided on the outer side of the column body 41 at the bottom of the connecting plate 5 to reinforce the connecting plate 5.

[0041] Two baffles 8 are provided at both ends of the two angle steels 7, and the two baffles 8 form a protective area to prevent birds from entering.

[0042] The column 4 includes a column body 41, which is usually made of high-strength steel to ensure that it can withstand various forces from the upper structure and the external environment. On the outside of the column body 41, at the bottom of the connecting plate 5, there is a reinforcing block 42. The reinforcing block 42 plays a crucial role, mainly used to reinforce the connecting plate 5.

[0043] When the railway rigid crossbeam suspension column is subjected to external forces such as wind and vibrations from train movement, the connecting plate 5 will be affected by complex forces. The presence of the reinforcing block 42 acts as a stable support for the connecting plate 5. The reinforcing block 42 is generally made of steel of the same or similar material as the column 41 and is firmly connected to the outside of the column 41 and the bottom of the connecting plate 5 by welding. Its shape is usually triangular, which has good stability and can effectively distribute the force borne by the connecting plate 5 to the column 41, preventing the connecting plate 5 from deforming or being damaged due to excessive local stress. When welding the reinforcing block 42, the welding process needs to be strictly controlled to ensure the welding quality, so that the reinforcing block 42 can fully exert its reinforcing function.

[0044] At both ends of the two symmetrically arranged angle steels 7 at the top of the support column 3, baffles 8 are installed. The two baffles 8 form a protective area, the main purpose of which is to prevent birds from entering. Bird activity is relatively frequent along railway lines. If birds enter the structure of the railway rigid beam suspension column, it may cause a series of problems.

[0045] Birds may nest on structures such as angle iron (7), and the nesting materials they use, such as twigs and grass, can affect the stability of the suspended column structure. For example, twigs may get stuck in critical connection points, affecting the tightness of bolts, or in windy weather, twigs may be blown by the wind, causing additional impact on the structure. In addition, bird droppings are corrosive, and if they accumulate on the suspended column structure over a long period of time, they can damage the protective coating on the steel surface, thereby accelerating the corrosion of the steel and shortening the service life of the suspended column.

[0046] The baffle 8 is typically made of lightweight and corrosion-resistant materials, such as aluminum alloy plates. Aluminum alloy plates offer advantages such as light weight, high strength, and corrosion resistance, adding minimal weight to the suspension column structure while maintaining good performance in long-term outdoor environments. The baffle 8 is fixed to both ends of the angle steel 7 using bolts or welding to ensure a secure connection. The protective area formed by the two baffles 8 effectively prevents birds from entering, ensuring the safe and stable operation of the railway rigid beam suspension column.

[0047] With the addition of column 4, reinforcing block 42, angle steel 7, and baffle 8, the structural stability and safety of the railway rigid crossbeam suspension column are further improved, enabling it to better adapt to the complex railway operating environment and reduce potential risks caused by structural damage and bird activity.

[0048] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
