[0042] In related technologies, when turnouts are trial-laid in the factory, the concrete turnout sleepers are leveled in advance using tooling, and then the turnouts are placed on the sleepers. Different products use different sleepers, and each time a new product is trial-laid, the entire turnout sleeper needs to be readjusted. In addition, the bottom of the turnout sleepers of some ballastless track beds is irregularly reinforced, and the bottom of the sleepers themselves is not flat, so the overall leveling is time-consuming and laborious, resulting in low efficiency of turnout trial-laying.

[0043] Based on the aforementioned technical problems, this application provides a turnout trial laying fixture, including a base, a crossbeam, and limiting components. During trial laying, the turnout, such as rail components, can be directly laid on the frame fixture, and the horizontal and vertical alignment of the turnout can be directly determined using the fixture frame. After the turnout trial laying is completed, the base plate is installed, eliminating the need for turnout sleepers for support. Therefore, the turnout trial laying fixture of this application solves the problem in related technologies where different products use different turnout sleepers, requiring overall readjustment during the trial laying of new products. This solves the problem of time-consuming and labor-intensive overall readjustment. Furthermore, the turnout trial laying fixture of this application replaces turnout sleepers, eliminating the need for repeated adjustment of the sleepers, saving trial laying time, and maximizing trial laying efficiency.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Reference Figure 1 and Figure 2As shown in the illustration, this application provides a turnout test-laying fixture 100, which can be applied to single turnouts or multiple turnouts. A single turnout is a type of railway turnout used to divide a track into two tracks. It typically consists of a main track and a branch track, and the direction of train travel is changed by moving the turnout's switch rail. A multiple turnout refers to a turnout system capable of dividing a track into multiple branch tracks. It can include double turnouts, triple turnouts, etc., depending on the number of branches. This embodiment does not limit this.

[0046] In the embodiments of this application, reference is made to Figure 1 and Figure 2 As shown, the turnout test laying fixture 100 may include a base 110, a crossbeam 120 and a limiting member 130. There are two bases 110, which are arranged opposite each other and both bases 110 extend along a first direction. The crossbeam 120 is disposed on the top of the base 110. The crossbeam 120 and the base 110 are slidably connected.

[0047] For example, the first direction can be referred to Figure 1 As indicated by the middle arrow in the X direction, two bases 110 are arranged opposite each other in the Y direction and extend along the X direction. For example, the base 110 can be a frame. For example, the frame can generally be made of steel, which has a large load-bearing capacity; for some lightweight applications, aluminum alloy can be used to reduce weight.

[0048] For example, the crossbeam 120 is disposed on top of the base 110, wherein the top of the base 110 can be understood as the top surface in the height direction of the base 110. For example, the crossbeam 120 may overlap the base 110. For example, the crossbeam 120 may generally be made of high-strength steel, such as carbon steel or alloy steel, which has good strength and durability and can withstand the weight of the turnout components and the stress generated during construction.

[0049] In the embodiments of this application, reference is made to Figure 1 As shown, there can be multiple crossbeams 120, which are spaced apart along a first direction and extend along a second direction. For example, the number of crossbeams 120 is not limited and can be arranged according to the actual product needs. The multiple crossbeams 120 can be spaced apart on the base 110.

[0050] Wherein, the first direction and the second direction intersect; for example, the second direction can be referred to... Figure 1 The direction indicated by the middle arrow Y. The first and second directions can be perpendicular, or there can be an angle between the first and second directions.

[0051] In this embodiment, the first direction and the second direction are perpendicular as an example. In this way, when installing the base 110 and the crossbeam 120, the base 110 is arranged longitudinally, which helps to provide good overall stability and can effectively bear the weight of the crossbeam 120 and the turnout. In addition, the longitudinal base 110 can distribute and bear the forces from different directions, ensuring the stability of the entire structure.

[0052] Furthermore, the horizontal arrangement of the crossbeams 120 on the base 110 serves several purposes. First, it helps to evenly distribute the load, reducing localized stress concentration, lowering the risk of structural deformation, and improving overall durability. Second, the horizontal arrangement of the crossbeams 120 provides a flat mounting surface, ensuring that all components of the turnout can be installed and adjusted in the correct positions. Third, the horizontal arrangement of the crossbeams 120 allows construction workers to operate on a relatively flat working surface, improving construction efficiency and safety. It also facilitates subsequent maintenance and repair work. Fourth, this design can adapt to different specifications and types of turnouts; by adjusting the spacing and position of the crossbeams 120, it can flexibly adapt to different construction needs. Fifth, the combination of the base 110 and the crossbeams 120 can typically adopt a modular design, facilitating transportation, assembly, and disassembly. This modular design helps to improve construction efficiency and reduce construction time.

[0053] In the embodiments of this application, reference is made to Figure 1 and Figure 2 As shown, the top of the crossbeam 120 is used to install the turnout 200. The top of the crossbeam 120 can be understood as the top surface in the height direction of the crossbeam 120. For example, the crossbeam 120 can be attached to the base 110.

[0054] Understandably, the turnout 200 is a key piece of equipment in the railway track system, used to guide trains from one track to another. It is a basic device for realizing the branching and intersection of railway lines and is widely used in stations, railway hubs and other places.

[0055] In the embodiments of this application, reference is made to Figure 2 and Figure 3 As shown, a limiting member 130 is provided at the connection between the crossbeam 120 and the turnout 200; the limiting member 130 is slidably connected to the crossbeam 120; the limiting member 130 is configured to fix the turnout 200.

[0056] For example, the limiting member 130 can be a limiting block. The limiting member 130 can be an elastic member, so that it can absorb a certain impact and vibration during the placement and adjustment of the turnout 200, and facilitate the assembly of the crossbeam 120 and the limiting member 130, reduce the direct stress and wear on the turnout 200 and the crossbeam 120, and extend the service life of the equipment.

[0057] For example, when the turnout 200 is placed on top of the crossbeam 120, the limiting member 130 is in a sliding state, sliding relative to the crossbeam 120 so that the limiting member 130 abuts against the turnout 200. When the position of the turnout 200 is fixed, the limiting member 130 is in a locked state, and the limiting member 130 is stationary relative to the crossbeam 120 to fix the turnout 200.

[0058] In this way, on the one hand, the sliding design allows the limiting member 130 to be flexibly adjusted in the sliding state to facilitate contact with specific parts of the turnout 200. This adjustability allows for precise positioning of the turnout 200 during installation, ensuring it is in the correct designed position. On the other hand, the sliding function of the limiting member 130 allows installers to make fine adjustments without moving the entire turnout 200, simplifying the installation process, reducing reliance on heavy equipment, and improving construction efficiency. Furthermore, once the position of the turnout 200 is determined, the limiting member 130 can switch from the sliding state to the locked state. At this time, the limiting member 130 is stationary relative to the crossbeam 120, providing a reliable fixing effect and preventing the turnout 200 from shifting due to vibration or other external forces during operation. By ensuring the precise and stable positioning of the turnout 200, the safety of the railway system can be significantly improved, and the potential safety risks caused by the displacement of the turnout 200 can be reduced. Furthermore, this design allows the limiting member 130 to adapt to different specifications and types of turnouts 200, providing greater flexibility. Moreover, since the turnout 200 can be firmly fixed, wear and failure caused by displacement or improper installation are reduced, thereby reducing maintenance and repair costs.

[0059] Therefore, the turnout trial laying fixture 100 provided in this embodiment solves the problem in related technologies that different products use different turnout sleepers, and the entire turnout needs to be readjusted when new products are trial laid. This solves the problem of time-consuming and labor-intensive overall leveling. At the same time, the turnout trial laying fixture 100 of this application replaces the turnout sleeper, eliminating the need to repeatedly adjust the turnout sleeper, saving trial laying time and maximizing trial laying efficiency.

[0060] In one possible implementation, refer to Figure 3 and Figure 4 As shown, the limiting member 130 may include a limiting part 131 and a limiting fastening part 132 connected to each other; the limiting part 131 is connected to the turnout 200. The top of the crossbeam 120 may be provided with a crossbeam groove 121, and the limiting fastening part 132 is slidably connected to the crossbeam groove 121.

[0061] For example, the limiting member 130 can be a "T" block.

[0062] Thus, on the one hand, the limiting part 131 is directly connected to the turnout 200 and is responsible for fixing the turnout 200 in a predetermined position. Its design needs to ensure that it can precisely match specific parts of the turnout 200 to provide effective support and fixation. On the other hand, the top of the crossbeam 120 is provided with a crossbeam groove 121, which can provide a sliding path for the limiting fastener 132. This design not only supports the sliding adjustment of the limiting part 130, but also provides additional fixing force in the locked state. Furthermore, the limiting fastener 132 is slidably connected to the crossbeam groove 121, allowing the limiting part 130 to be adjusted on the crossbeam 120. Through this sliding connection, the limiting fastener 132 can move flexibly during installation to facilitate the precise positioning of the turnout 200.

[0063] In addition, once the position of the turnout 200 is determined, the limiting fastener 132 can be fixed in the crossbeam groove 121 by a locking mechanism such as bolts or clamps. This fixing method provides reliable stability and prevents the turnout 200 from shifting due to vibration or other external forces during operation.

[0064] In one possible implementation, refer to Figure 4 As shown, the crossbeam groove 121 may include a first groove section 1211 and a second groove section 1212 that are interconnected. The first groove section 1211 is located near the turnout 200. The cross-sectional area of ​​the first groove section 1211 is smaller than the cross-sectional area of ​​the second groove section 1212. The first end of the limiting fastener 132 can extend into the second groove section 1212 and rotate within the second groove section 1212.

[0065] It should be noted that cross-sectional area refers to the area formed by the cut surface after an object is cut by a plane perpendicular to a specific direction. This plane is usually perpendicular to the length direction of the object.

[0066] This design has several advantages. First, the first groove segment 1211, positioned close to the turnout 200, provides a more precise limiting effect due to its smaller cross-sectional area. This ensures that the limiting member 130 provides more accurate support and positioning near the turnout 200. Second, the larger cross-sectional area of ​​the second groove segment 1212 allows the first end of the limiting fastener 132 to rotate within it, providing flexible adjustment capabilities. This allows the limiting member 130 to be fine-tuned during installation to achieve optimal positioning of the turnout 200. Furthermore, by allowing the limiting fastener 132 to rotate within the second groove segment 1212, it is possible to... A more robust locking mechanism is achieved. Once the position of the turnout 200 is determined, the limiting fastener 132 can be fixed in the appropriate position by rotation or other locking methods to ensure that the turnout 200 will not shift during operation. Furthermore, the installation process of the turnout 200 is simplified. Construction personnel can first insert the limiting fastener 132 into the second groove section 1212 for initial positioning, and then achieve precise adjustment by rotation and sliding, and finally lock the limiting component 130. In addition, by designing groove sections with different cross-sectional areas, stress concentration can be effectively reduced, and the service life of the crossbeam 120 and the limiting component 130 can be extended.

[0067] Therefore, through the design of the crossbeam groove 121, the installation and fixing of the limiting member 130 in this embodiment becomes more efficient and reliable, ensuring the installation quality of the turnout 200 and the safety of railway transportation.

[0068] In one possible implementation, the limiting part 131 may have a limiting through hole, the inner peripheral wall of the limiting through hole is provided with a limiting thread, the outer peripheral wall of the limiting fastening part 132 is provided with a fastening thread, and the limiting part 131 and the limiting fastening part 132 are screwed together by the limiting thread and the fastening thread.

[0069] In this way, the threaded connection allows for precise linear adjustment between the limiting part 131 and the limiting fastener 132. By rotating the limiting fastener 132, the position of the limiting member 130 can be finely adjusted to achieve precise positioning of the turnout 200; moreover, the threaded connection provides a reliable fixing method and also makes installation and disassembly easier.

[0070] In one possible implementation, refer to Figure 2 As shown, it may also include a base fastener 140; the base fastener 140 includes a fastening rotating part and a fastening connecting part that are connected to each other; the top of the base 110 may be provided with a base groove 111, and the fastening rotating part is slidably connected to the base groove 111.

[0071] Specifically, the end of the crossbeam 120 is provided with a crossbeam through hole, the inner peripheral wall of the crossbeam through hole is provided with a crossbeam thread, the outer peripheral of the fastening connection part is provided with a connecting thread, and the crossbeam 120 and the fastening connection part are screwed together by the crossbeam thread and the connecting thread.

[0072] For example, the base fastener 140 can be a "T" block.

[0073] In this way, the base fastener 140 is slidably connected to the base groove 111 via the fastening rotating part, allowing for position adjustment during installation. This design ensures a stable connection between the base 110 and the crossbeam 120, improving the overall structural stability. The fastening rotating part's design allows sliding within the base groove 111, enabling the base fastener 140 to be flexibly adjusted in position. Furthermore, the combination of threaded and sliding connections provides excellent vibration resistance, effectively resisting vibration and impact during railway operation and maintaining structural stability.

[0074] In one possible implementation, the base groove 111 may include a third groove segment and a fourth groove segment that are interconnected, with the third groove segment located close to the crossbeam 120; wherein the cross-sectional area of ​​the third groove segment may be smaller than the cross-sectional area of ​​the fourth groove segment; and the fastening rotating part is located in the fourth groove segment.

[0075] In this way, on the one hand, the third groove segment is located close to the crossbeam 120, and its smaller cross-sectional area provides a more precise limiting effect, which helps to initially position the base fastener 140 during installation and ensure its precise position close to the crossbeam 120; on the other hand, the larger cross-sectional area of ​​the fourth groove segment allows the fastener rotating part to rotate and slide within it, providing flexible adjustment capabilities, so that the base fastener 140 can be fine-tuned during installation to achieve the best fixing effect; furthermore, by designing groove segments with different cross-sectional areas, stress concentration can be effectively reduced, the vibration resistance of the structure can be enhanced, and the stability of the base 110 can be maintained.

[0076] In one possible implementation, refer to Figure 3 As shown, it may also include a crossbeam pad 150, with both sides of the crossbeam pad 150 abutting against the bottom of the crossbeam 120 and the top of the base 110 respectively along the height direction of the crossbeam pad 150.

[0077] For example, the beam pad 150 may be made of a high-strength material, such as steel, composite material or engineering material, to ensure its durability under pressure and vibration. The thickness and dimensions of the beam pad 150 may be designed according to specific engineering requirements to adapt to different loads and environmental conditions.

[0078] For example, the crossbeam pad 150 is disposed between the crossbeam 120 and the base 110 along its height direction, with its two ends abutting against the crossbeam 120 and the base 110 respectively, which helps to form a stable support structure.

[0079] In this way, on the one hand, the crossbeam pad 150 provides a uniform contact surface between the crossbeam 120 and the base 110, which helps to evenly distribute the load on the crossbeam 120 to the base 110, reducing local stress concentration and lowering the risk of structural deformation and damage; on the other hand, the crossbeam pad 150 can effectively buffer vibrations and impacts from train operation, reducing the direct impact on the crossbeam 120 and the base 110, extending the service life of the structure, and improving the overall operational stability; furthermore, the crossbeam pad 150 can compensate for errors in the installation process to a certain extent, providing a flat contact surface to ensure good connection between the crossbeam 120 and the base 110; and finally, by adding a support layer between the crossbeam 120 and the base 110, the crossbeam pad 150 improves the stability of the entire structure and prevents displacement caused by vibration or other external forces during operation. On the other hand, as an independent component, the crossbeam pad 150 can be replaced or maintained individually when needed without disassembling the entire structure, which simplifies maintenance work and reduces maintenance costs. Moreover, the design of the crossbeam pad 150 can be adjusted according to different engineering requirements to adapt to different track systems and environmental conditions, providing greater design flexibility.

[0080] In one possible implementation, refer to Figure 1 As shown, the turnout test laying fixture 100 can be a frame fixture. Along the first direction, adjacent crossbeams 120 are spaced apart and surround to form a crossbeam area 170. Each crossbeam area 170 is used to place the turnout sleeper 300 and the turnout sleeper pad 400. The turnout sleeper pad 400 is set at the connection between the turnout sleeper 300 and the turnout 200.

[0081] Among them, turnout sleeper 300 refers to the sleeper used to support and fix railway turnouts. Turnouts are a key component of the railway track system, used to allow trains to switch from one track to another. The function of the turnout sleeper is to provide a stable foundation, ensuring that the various components of the turnout (such as the switch rail, stock rail, and connectors) remain in the correct position and angle to guarantee the safe and smooth passage of trains through the turnout.

[0082] Compared to ordinary sleepers, turnout sleepers 300 typically have different lengths and shapes to accommodate the complex structure of the turnout 200. The material of the turnout sleeper 300 can be wood, concrete, or steel, depending on the design requirements and operating environment of the turnout 200. Due to the complex mechanical conditions at the turnout 200, the turnout sleeper 300 needs to possess high strength and durability.

[0083] In this embodiment, the turnout trial laying fixture 100 is a frame-type fixture. This frame-type fixture provides a stable structural platform that effectively supports the weight of the turnout 200 and the turnout sleeper 300. This stability helps maintain the precise position and shape of the turnout 200 during the trial laying process. Simultaneously, the frame-type fixture provides a safe working environment, reducing the risk of accidents caused by component displacement or instability during construction.

[0084] In this embodiment, each crossbeam area 170 is used to place the turnout sleeper 300 and the turnout sleeper pad 400. The design of the crossbeam area 170 provides a clear placement position for the turnout sleeper 300 and the turnout sleeper pad 400. Moreover, since the crossbeam area 170 provides a fixed reference position, it reduces installation errors caused by human factors and improves the overall reliability of the turnout 200 system.

[0085] In this embodiment, the turnout sleeper pad 400 is disposed at the connection between the turnout sleeper 300 and the turnout 200, which helps to disperse and buffer the stress generated during the operation of the turnout 200, reduce the direct impact on the structure, and extend the service life of the component.

[0086] In one possible implementation, refer to Figure 2 As shown, it may also include an elastic element 160, which is used to connect with the turnout sleeper 300 and the turnout 200 respectively.

[0087] For example, the elastic element 160 can be a spring bar; or, the elastic element 160 can be a spring or a sheet. In this embodiment, a spring bar is mainly used as an example for explanation. For example, the elastic element 160 can be a separate gasket, pad, or elastic element integrated into other structures.

[0088] Thus, on the one hand, the introduction of the elastic element 160 provides flexibility and buffering capacity for the connection between the turnout 200 and the turnout sleeper 300, absorbing and mitigating the dynamic loads and vibrations generated when the train passes, reducing the direct impact on the turnout 200 and the turnout sleeper 300, and lowering the risk of structural fatigue and damage. On the other hand, by absorbing vibrations, the elastic element 160 can also significantly reduce the noise generated when the train is running, improving the comfort of the railway environment. Furthermore, the buffering effect of the elastic element 160 helps to improve the smoothness of the train when passing through the turnout 200, reducing bumps and impacts caused by unevenness, and improving passenger comfort. Moreover, the elastic element 160 can be adjusted according to different turnout 200 designs and operating conditions to provide the best buffering effect, while also helping to disperse the stress on the turnout 200 and the turnout sleeper 300, preventing local stress concentration, and protecting the integrity of the structure.

[0089] In one possible implementation, a hydraulic device may also be included, configured to generate power using liquid pressure for raising the height of the forklift 300; or, it may be used to raise the height of the base 110 and the crossbeam 120.

[0090] Hydraulic systems utilize the pressure of a fluid (typically hydraulic oil) to generate power. A hydraulic pump pressurizes the fluid and transmits it through pipes to a hydraulic cylinder, which in turn moves a piston, thereby lifting the fork 300, crossbeam 120, or base 110. For example, a hydraulic system typically includes components such as a hydraulic pump, hydraulic cylinder, control valves, and a reservoir.

[0091] In this way, on the one hand, the hydraulic device can achieve precise height adjustment, which is suitable for the installation and commissioning process of turnout 200 that requires high-precision positioning; on the other hand, the hydraulic device can provide powerful force, which is suitable for lifting heavy structural components, such as turnout sleepers 300 and crossbeams 120, reducing the burden of manual operation; furthermore, the hydraulic device provides smooth power output, reducing the impact and vibration on the structure, protecting the integrity of the equipment, and can be integrated with automated control and remote operation to improve construction efficiency and safety.

[0092] Alternatively, the turnout test laying fixture 100 may also include a lifting device, which uses mechanical power to lift the height of the turnout sleeper 300, or it may be used to lift the height of the base 110 and the crossbeam 120.

[0093] The lifting device uses mechanical power (such as electric motor, gear transmission, screw jack, etc.) to lift the turnout sleeper 300, crossbeam 120 or base 110. It is usually portable or fixed and is suitable for different construction environments.

[0094] Thus, lifting devices are typically lightweight, easy to deploy and operate quickly on-site, and suitable for temporary or small-scale adjustment tasks. In addition, mechanical lifting devices are usually low-cost and have high reliability and durability, enabling them to work for extended periods in harsh environments.

[0095] It should be noted that in this embodiment, hydraulic devices and lifting devices can be used together, which not only simplifies the construction process and improves the safety and reliability of the system, ensuring the smooth operation of railway transportation, but also enables the installation and maintenance of turnouts to achieve higher efficiency and precision.

[0096] The operation steps of the turnout trial laying fixture in this embodiment are as follows:

[0097] Adjust the position of the crossbeam of the frame-type fixture according to the spacing between the turnout sleepers. For example, the position of the crossbeam on the base can be adjusted by sliding it through a limiting member.

[0098] The turnout sleepers and base plates are pre-placed in designated locations. For example, the designated locations can be pre-determined based on the turnout design drawings and engineering specifications. For instance, on a construction site, the designated locations are usually clearly marked using markers, coordinates, or other positioning tools.

[0099] Adjust the level and height of the crossbeam. For example, the level of the crossbeam can be adjusted by sliding the limiting member, or the height of the crossbeam can be adjusted by a hydraulic device or a lifting device.

[0100] Place small items such as spring clips and bolts;

[0101] Place the rails and frogs in their corresponding positions, and use limiting blocks to fix the rails in place. For example, the rails are the turnouts in this embodiment, and the frogs are components used to guide the train wheels from one track to another, usually installed at the intersection of two tracks.

[0102] Adjust the turnouts to ensure that the assembly and testing items such as track gauge and track spacing meet the requirements.

[0103] A hydraulic device, in conjunction with a turnout sleeper lifting fixture, is used to lift the turnout sleeper and its base plate as a whole. The base plate is then hung on the rail and secured, and the turnout sleeper is then fastened to the base plate. For example, a jack can be used to lift the turnout sleeper.

[0104] Fine-tuning the dimensions of the turnout sleepers during trial laying. Exemplary measuring tools may include laser rangefinders, steel rulers, feeler gauges, etc., but this embodiment is not limited to these.

[0105] The turnout trial laying fixture provided in this application includes a base, a crossbeam, and limiting components. During trial laying, the turnout, such as rail components, can be directly laid on the frame fixture, and the level and height of the turnout can be directly determined using the fixture frame. After the turnout trial laying is completed, the base plate is installed, eliminating the need for turnout sleepers for support. Therefore, the turnout trial laying fixture of this application solves the problem in related technologies where different products use different turnout sleepers, requiring overall readjustment during the trial laying of new products. This solves the problem of time-consuming and labor-intensive overall readjustment. Furthermore, the turnout trial laying fixture of this application replaces turnout sleepers, eliminating the need for repeated adjustment of the sleepers, saving trial laying time and maximizing trial laying efficiency.
