Specific Embodiments

[0028] The following will combine the accompanying drawings in the embodiments of the present invention Figure 1-8 , and clearly and completely describe the technical solutions 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 embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0029] A high-speed turnout assembly platform, (as shown in Figure 1 ) is composed of a horizontal height adjustment system 1, a cross beam 2, a fixed backing plate 3, and a fastening system 4; the horizontal height adjustment system 1 is used to adjust the height position and horizontal position of the cross beam 2; the bottom of the cross beam 2 is connected to the top end of the horizontal height adjustment system 1, and the fixed backing plate 3 is fixedly installed on the upper horizontal plane of the cross beam 2. The fixed backing plate 3 is used to set the high-speed turnout, and the fastening system 4 is arranged outside the fixed backing plate 3. The fastening system 4 is used to stably press and constrain the high-speed turnout.

[0030] It should be noted that: The horizontal height adjustment system 1 equipped on the platform can accurately adjust the height position and horizontal position of the cross beam 2. This function ensures the precise positioning of the turnout during the assembly process, enabling the geometric dimensions of each part of the assembled turnout to accurately meet the design requirements, improving the assembly accuracy and quality of the turnout. The cross beam 2, as the main support structure of the platform, is connected to the ground or foundation through the horizontal height adjustment system 1, providing stable support for the turnout. The fixed backing plate 3 further enhances the stability of the turnout during the assembly process, preventing the turnout from shifting or deforming during the assembly process. The fastening system 4 is arranged outside the fixed backing plate 3 and is used to stably press and constrain the high-speed turnout, not only improving the safety of the turnout during the assembly process, but also ensuring the stability and reliability of the turnout during subsequent use. The fast response and high efficiency of the fastening system 4 make the assembly process of the turnout more efficient and convenient. The platform adopts a modular design concept, that is, the horizontal height adjustment system 1, the cross beam 2, the fixed backing plate 3, and the fastening system 4 can exist independently and be combined for use, making the platform highly flexible and scalable, and can be quickly adjusted and optimized according to different turnout types and assembly requirements. The platform has a simple structure, low cost, convenient use and operation, can be reused, greatly reducing the cost investment during the turnout assembly process and improving economic benefits; at the same time, the reuse of the platform also helps to reduce resource waste and environmental pollution.

[0031] Preferably: (as shown in Figure 2 ) the horizontal height adjustment system 1 adjusts the horizontal position of the cross beam 2 through a horizontal bolt 11; the horizontal height adjustment system 1 adjusts the height position of the cross beam 2 through an adjustment gasket 12.

[0032] It should be noted that the design of the horizontal bolt 11 allows for fine adjustment, enabling precise control of the horizontal position of the crossbeam. The adjustment method of the horizontal bolt 11 is intuitive and easy to operate, without the need for complex tools or skills, and maintenance personnel can quickly get started to make adjustments for horizontal fine displacement. After adjustment, the adjustment method of the horizontal bolt 11 can maintain a stable fixed state, ensuring that the crossbeam will not undergo horizontal displacement during long-term use. The design of the adjusting shim 12 allows for addition or subtraction according to needs, so as to flexibly adjust the height position of the crossbeam. Different shim thicknesses can achieve different degrees of adjustment to meet various assembly requirements. If it is found during use that the height position of the crossbeam 2 needs to be adjusted, the adjusting shim 12 can be conveniently replaced or added or subtracted.

[0033] Preferably, the adjusting shim 12 is a rectangular stainless steel sheet, and the specifications of the adjusting shim 12 are 200mm * 75mm * specification thickness, where the specification thickness is 0.5mm, 1mm, 2mm.

[0034] It should be noted that the stainless steel material of the adjusting shim 12 has excellent corrosion resistance and can be used for a long time in harsh environments such as humidity, acid and alkali without being prone to rust or corrosion, thus extending the service life of the adjusting shim 12 and reducing the replacement frequency and maintenance cost caused by corrosion. Stainless steel has high mechanical strength and can withstand large pressures and shear forces, ensuring that it will not deform or be damaged when adjusting the height position of the crossbeam, guaranteeing the accuracy and stability of the adjustment. The rectangular size design of 200mm * 75mm is reasonable, which is not only convenient for processing and manufacturing, but also convenient for installation and replacement; at the same time, this size is also applicable to various types of turnout assembly platforms, with good versatility. Three specification thicknesses of 0.5mm, 1mm, and 2mm are provided, and can be flexibly selected according to actual needs to achieve precise adjustment of the height position of the crossbeam. This design makes the adjusting shim 12 more flexible and variable when dealing with different assembly requirements. By adding or subtracting adjusting shims 12 with different thicknesses, precise adjustment of the height position of the crossbeam can be achieved. This adjustment method is simple and intuitive, easy to operate, and has high adjustment accuracy, which can meet the strict requirements during the turnout assembly process. After installation, the adjusting shim 12 can maintain a stable supporting state, ensuring that the crossbeam will not undergo height position changes during long-term use. This stability is crucial for ensuring the assembly quality of the turnout and subsequent use safety. Compared with other materials or complex-structured adjusting devices, the cost of the stainless steel adjusting shim 12 is relatively low, and its standardized production and versatility further reduce the procurement and replacement costs.

[0035] Furthermore, the horizontal height adjustment system 1 includes a base 13, support rails 14, and fasteners 15. The bottom of the base 13 is fixedly installed on the ground. On the upper plane of the base 13, there are two parallel support rails 14 spaced apart. The support rails 14 are respectively constrained and fixed in position by two sets of fasteners 15. An adjusting gasket 12 is inserted between the top surface of the support rail 14 and the bottom surface of the crossbeam 2. A horizontal bolt 11 is installed between the vertical side of the web of the support rail 14 and the vertically arranged welded connection plate 21 at the bottom of the crossbeam 2.

[0036] It should be noted that: The bottom of the base 13 is fixedly installed on the ground, providing a stable foundation for the entire adjustment system and ensuring the stability of the system during use. There are two parallel support rails 14 spaced apart on the upper plane of the base 13. This double-rail design enhances the support capacity, enabling the crossbeam 2 to remain stable when subjected to external forces and not prone to tilting or deformation. The support rails 14 are respectively constrained and fixed in position by two sets of fasteners 15. This design not only ensures the stability of the support rails 14 but also facilitates disassembly and adjustment when needed. An adjusting gasket 12 is inserted between the top surface of the support rail 14 and the bottom surface of the crossbeam 2. By replacing adjusting gaskets of different thicknesses, the height position of the crossbeam 2 can be flexibly adjusted to meet different assembly requirements. A horizontal bolt 11 is installed between the vertical side of the web of the support rail 14 and the vertically arranged welded connection plate 21 at the bottom of the crossbeam 2. By rotating the horizontal bolt 11, the horizontal position of the crossbeam 2 can be adjusted to ensure the precise assembly of the turnout. The design of the adjusting gasket 12 and the horizontal bolt 11 makes the maintenance and inspection of the system relatively simple. When adjustment or replacement is required, only the corresponding fasteners or bolts need to be loosened for operation. Components such as the base 13, support rails 14, fasteners 15, adjusting gasket 12, and horizontal bolt 11 can all be produced in a standardized manner, which not only reduces the manufacturing cost but also facilitates subsequent repair and replacement. By precisely adjusting the height position and horizontal position of the crossbeam 2, the assembly accuracy of the turnout can be significantly improved, ensuring the stability and safety of the turnout during subsequent use. This adjustment system can adapt to the assembly requirements of different types of turnouts. By adjusting the thickness of the adjusting gasket 12 and the position of the horizontal bolt 11, various complex assembly scenarios can be flexibly handled.

[0037] Furthermore, the base 13 is directly cast and fixedly connected to the ground, or the base 13 is installed in the foundation of the turnout laying site using anchor bolts.

[0038] It should be noted that: The direct casting connection method has strong structural stability, high construction efficiency, and good durability. The connection method using anchor bolts is flexible in installation, convenient for disassembly and repair, has strong bearing capacity, and high adaptability.

[0039] Furthermore: (such as Figure 3 、 Figure 4As shown in the figure, the crossbeam 2 is composed of a welded connecting plate 21, connecting angle steels 22, left and right channel steels 23, a middle channel steel 24, a screw rod 25, a nut I 26, and a gasket 27. A middle channel steel 24 with a downward opening is arranged between the left and right channel steels 23 with inward openings and symmetric left and right. The screw rod 25 horizontally penetrates through the horizontal center lines of the left and right channel steels 23 and the middle channel steel 24. The gasket 27 is used to adapt and adjust the gap between the middle channel steel 24 and the vertical sides of the left and right channel steels 23. The nut I 26 is screwed onto the protruding end of the screw rod 25, and a gasket 27 is placed on the inner side of the nut I 26 to fasten and connect the left and right channel steels 23 and the middle channel steel 24 into an integrated crossbeam main body. The same connecting angle steel 22 is fixedly connected to the bottoms of the left and right channel steels 23. The connecting angle steel 22 is used to ensure the flatness of the crossbeam 2. The welded connecting plate 21 vertically welded and fixedly connected to the bottom of the crossbeam 2 is provided with a horizontally penetrating threaded hole. The threaded hole is screwed and fitted with a horizontal bolt 11. The end of the rod body of the horizontal bolt 11 abuts against the vertical side of the web of the support rail 14 to finely adjust the horizontal position of the crossbeam 2.

[0040] It should be noted that: The crossbeam 2 is composed of left and right channel steels 23 with inward openings and symmetric left and right and a middle channel steel 24 with a downward opening. This design enhances the section modulus and bending resistance of the crossbeam, enabling it to bear greater loads without being easily deformed. The left and right channel steels 23 and the middle channel steel 24 are fastened and connected into an integrated crossbeam main body through the screw rod 25 and the nut I 26, forming a stable crossbeam main body structure. The gasket 27 is used to adapt and adjust the gap between the middle channel steel 24 and the vertical sides of the left and right channel steels 23, ensuring the close fit between components and improving the overall stability of the crossbeam. The use of the gasket 27 also facilitates fine adjustment during the assembly process to compensate for manufacturing and installation errors. By rotating the horizontal bolt 11, the horizontal position of the crossbeam 2 can be finely adjusted to closely abut against the vertical side of the web of the support rail 14, ensuring the precise position of the crossbeam in the horizontal direction. The components of the crossbeam 2 adopt a modular design, which is convenient for processing, transportation, and on-site assembly. The connection method between components is simple and reliable, reducing the assembly difficulty and cost. The design of the connecting angle steel 22 helps to ensure the flatness of the crossbeam 2 and prevent it from being distorted or deformed during use. Each component of the crossbeam 2 adopts high-precision processes during processing to ensure its dimensional accuracy and shape accuracy. During the assembly process, through precise measurement and adjustment, the assembly accuracy and overall performance of the crossbeam can be further improved. The component design of the crossbeam 2 is convenient for inspection and maintenance. When a component is damaged or worn, it can be easily replaced or repaired. The crossbeam 2 is made of high-quality steel, undergoes anti-corrosion treatment and surface coating, and has good corrosion resistance and durability. Under normal use conditions, the crossbeam 2 can maintain stable performance and service life for a long time.

[0041] Furthermore: The crossbeam 2 located at the turnout position reserves a turnout switch electro-signal interface.

[0042] It should be noted that: reserved interfaces are provided to reduce on-site workload, standardized interfaces are used to facilitate quick connection. It is compatible with a variety of signal equipment, allowing for flexible adjustment and expansion; professionally designed to ensure firm connection; reducing interference and guaranteeing signal transmission. It is easy to access and operate, with a modular design for easy replacement; it supports the access of intelligent devices to promote automation upgrades.

[0043] Furthermore: (as Figure 5 ) Located in the switch area of the high-speed turnout, the upper end surface of the fixed tie plate 3 is provided with a slide bed plate 31, a rail cant plate 32 and a limit block 33; the slide bed plate 31 is used for the switching slide of the switch point rail. (as Figure 6 ) Located in the fixed part of the high-speed turnout, the upper end surface of the fixed tie plate 3 is provided with a rail cant plate 32 and a limit block 33. The rail cant plate 32 is arranged below the installation position of the stock rail or guide rail. The limit block 33 is arranged on one side or both sides of the rail cant plate 32. Specifically, in the switch area of the high-speed turnout, it is sufficient to arrange the limit block 33 on one side of the rail cant plate 32. In the fixed part of the high-speed turnout, the limit block 33 is arranged on both sides of the rail cant plate 32. A fastening system 4 is provided outside the rail cant plate 32.

[0044] It should be noted that: the slide bed plate 31 is specifically designed for the switching slide of the switch point rail, its surface is smooth and wear-resistant, which can ensure that the point rail moves smoothly during the switching process, reduce the frictional resistance, and improve the switching efficiency. When the slide bed plate 31 is made of high-strength and wear-resistant materials, it can effectively reduce the wear between the point rail and the tie plate, and extend the service life of the point rail and the tie plate. The rail cant plate 32 is arranged below the installation position of the stock rail or guide rail to provide stable support for the track. The limit block 33 arranged on one side or both sides of the rail cant plate 32 can limit the lateral displacement of the track and prevent the rail components from shifting. The design of the rail cant plate 32 can adapt to the rail cant of different tracks to ensure the close fit between the rail components and the fixed tie plate, and improve the stability. The setting of the limit block 33 further enhances the stability of the track, prevents longitudinal or lateral displacement, facilitates the maintenance personnel to adjust the position of the rail components, and is convenient for quick positioning.

[0045] Furthermore: (as Figure 7 、 Figure 8As shown, the fastening system 4 is composed of a fixing plate 41, a movable wrench 42, a fastening head 43, a threaded rod 44, and a nut II 45. The bottom end of the fixing plate 41 is fixedly connected to the fixed backing plate 3 by welding, and the fixing plate 41 is inclined outward by 15° to 20° to prevent the rail components from colliding with the fastening system 4 during installation. The fixing plate 41, the movable wrench 42, and the fastening head 43 are sequentially connected by bolt bolting in a three-point fixing manner. One or more rail base slope adjustment holes 421 are provided at the connection position between the movable wrench 42 and the fastening head 43. The rail base slope adjustment holes 421 are used for the adaptive assembly of rail components with different rail base slopes. The front part of the fastening head 43 is of a hollow cylindrical 431 structure. The threaded rod 44 is inserted into the hollow hole of the hollow cylindrical 431 structure. The upper and lower nuts II 45 are used to adjust and lock the telescopic position of the rod body of the threaded rod 44. The bottom end of the rod body of the threaded rod 44 presses against the upper end face of the rail limb of the turnout rail component to lock the position of the rail component.

[0046] It should be noted that: The bottom end of the fixing plate 41 is fixedly connected to the fixed backing plate 3 by welding, ensuring a firm connection between the fastening system and the backing plate. The fixing plate 41 is inclined outward by 15° to 20°, and this design effectively prevents the rail components from colliding with the fastening system 4 during installation, improving the installation efficiency and safety. The fixing plate 41, the movable wrench 42, and the fastening head 43 are sequentially connected by bolt bolting in a three-point fixing manner, which enhances the overall stability of the fastening system and ensures that there will be no loosening or displacement during the fastening process. One or more rail base slope adjustment holes 421 are provided at the connection position between the movable wrench 42 and the fastening head 43, and this design enables the fastening system to adapt to the assembly requirements of rail components with different rail base slopes. By adjusting the relative position of the movable wrench 42 and the fastening head 43, the height and angle of the fastening head 43 can be conveniently changed to adapt to rail components with different rail base slopes. The front part of the fastening head 43 is of a hollow cylindrical 431 structure, and the threaded rod 44 is inserted into the hollow hole, and this design enables the threaded rod 44 to be telescopically adjusted. By using the upper and lower nuts II 45 to adjust and lock the telescopic position of the rod body, the extended length of the threaded rod 44 can be accurately controlled, thereby achieving precise locking of the position of the rail component. The bottom end of the rod body of the threaded rod 44 presses against the upper end face of the rail limb of the turnout rail component, and this design ensures that the rail component receives sufficient pressure during the fastening process, thereby improving the stability and reliability of the rail component. The fastening system 4 has a long service life and is more reliable, reducing the maintenance cost.

[0047] Furthermore, the fastening system 4 is arranged at intervals of three fixed pads 3. Arranging the fastening system 4 at intervals of three fixed pads 3 significantly reduces the number of fastening points compared to setting a fastening system for each pad, reduces the installation and maintenance workload, and improves the construction efficiency. The reduction in the number of fastening points enables the operator to more conveniently operate the fastening system during installation and maintenance. Arranging the fastening system at intervals can more reasonably distribute the fastening force, avoiding deformation or loosening of the pads caused by excessive or insufficient local fastening force. By arranging the fastening system at intervals, a more stable overall structure can be formed. The method of arranging the fastening system 4 at intervals of three fixed pads 3 has high flexibility and can adapt to the requirements of different turnout structures. During actual use, if it is found that the fastening effect in a certain area is not good or there are other problems, the fastening system 4 in this area can be conveniently adjusted. Arranging the fastening system at intervals reduces the number of fastening systems used, thereby reducing material consumption and costs.

[0048] The working principle of the present invention is as follows: The platform of the present invention is arranged at intervals of three sleeper spacings, and the specific size of the platform is close to the length of the sleepers at the turnout position where it is located. Electrical interface installation is reserved on the cross beam 2 at the switch position, and fixed pads 3 are customized according to the actual situation of the turnout on the platforms at different positions in sequence, and the fastening system 4 is installed. Before turnout assembly, the adaptability adjustment of the height position of the horizontal height adjustment system 1 of the cross beam 2 should be carried out by inserting adjusting shims 12 of different specifications; during the turnout assembly process, when the horizontal direction needs to be adjusted, the horizontal bolts 11 can be used for fine adjustment of the horizontal position of the cross beam 2.

[0049] It can be found from the above description that the fastening system of the present invention can achieve stable fastening of the turnout, and the disassembly is simple. Just loosen the nut II 45, which improves the turnout assembly efficiency.

[0050] The horizontal bolts 11 of the present invention can achieve fine adjustment of the horizontal position of the cross beam 2, and adjusting shims 12 of different specifications can achieve adjustment of the height position of the cross beam 2, so as to ensure that the height and horizontal position of the turnout are within the specified range.

[0051] The present invention is designed according to the actual situation of high-speed turnouts, effectively reducing the number of cross beams 2 of similar sleepers, reducing costs, reducing the assembly volume, and improving the assembly efficiency; the platform of the present invention is a turnout sleeperless structure, which can reduce the procurement of assembly sleepers and reduce the development cost of the assembly platform. The cross beam 2 of the present invention is mainly fixed by using channel steel, is detachably connected to the fixed pad 3, has a light weight, a small adjustment resistance, a modular design, is easy to inspect and maintain, has good durability, can be reused and reduces costs.

[0052] It should be understood that although this specification is described in accordance with one embodiment, it does not mean that this embodiment only contains an independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in this embodiment can also be appropriately arranged and combined to form other embodiments that can be understood by those skilled in the art.
