Description

Technical Field

[0001] This utility model relates to the field of railway rail transportation technology, specifically a high-speed rail 100-meter rail transport vehicle. Background Technology

[0002] In modern railway rail transportation, compared to 25m rails, 100m rails significantly reduce the time spent on manual disassembly and assembly and on-site welding. Compared to 500m rails, 100m rails also significantly reduce vehicle usage and subsequent maintenance costs. Therefore, from the perspective of loading, unloading and transportation advantages, 100m rails are currently the most widely used type of rail in railway rails.

[0003] However, existing rail transport train sets used for transporting 100-meter rails have relatively low technical requirements and are generally only suitable for conventional railway operations, failing to meet the requirements of high-speed operation on high-speed railway lines. For example, the "rail transport train set" disclosed in Chinese utility model patent CN214874786U has low requirements for rail stability, resulting in poor safety. If this transport train set is used for high-speed rail operations, whether at high speeds or during turns, the insufficient stability of the long rails on the train set, especially in the lateral direction without limit, makes it highly susceptible to lateral displacement between the rails, leading to rail tilting or even detachment and causing safety accidents. Utility Model Content

[0004] In view of this, this utility model proposes a high-speed rail 100-meter rail transport vehicle to solve the technical problem that the existing 100-meter rail transport vehicle has no lateral displacement of the rails when traveling at high speed and turning during high-speed rail operations, which makes the rails easy to tilt or even fall off, thus easily causing safety accidents.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a high-speed rail 100-meter rail transport vehicle, comprising:

[0007] The main body of the vehicle group includes several transport cars, a locking car, and several transport cars connected in sequence;

[0008] A support and limiting module is installed on the transport vehicle and includes at least one rail support component and at least one rail limiting component. The support and limiting modules on the transport vehicles located at both ends of the main body of the vehicle group have the rail limiting component installed on both sides of the rail support component. The support and limiting modules on the other transport vehicles have the rail limiting component installed on one side of the rail support component.

[0009] In some embodiments, the transport vehicle includes a first transport vehicle located at both ends of the main body of the vehicle group. The first transport vehicle is provided with a first support and limiting module. The first support and limiting module includes the rail limiting component, two rail support components and the rail limiting component arranged sequentially along the length of the rail.

[0010] In some embodiments, the transport vehicle includes a second transport vehicle located between the transport vehicles at both ends of the main body of the vehicle group and the locking vehicle. The second transport vehicle is provided with a second support and limiting module. The second support and limiting module includes the rail limiting component, two rail support components or two rail support components and rail limiting component arranged sequentially along the length of the rail.

[0011] In some embodiments, the rail support assembly includes a support frame, a rotating frame, and a placement platform. The placement platform is arranged in two layers, with the lower placement platform having its two sides fixedly connected to the support frame and the rotating frame, respectively, and the rotating frame being located on the side of the placement platform close to the central axis of the train body. One end of the upper placement platform is connected to the rotating frame via a transmission, and its other end overlaps with the support frame.

[0012] In some embodiments, the rotating frame includes a rotating shaft, a first sleeve, a second sleeve, and reinforcing ribs. The bottom of the rotating shaft is rotatably connected to the lower placement platform. The first sleeve and the second sleeve are sequentially sleeved onto the rotating shaft from bottom to top. The reinforcing ribs are evenly distributed outside the first sleeve. The second sleeve has an avoidance notch. The upper placement platform is connected to the rotating shaft through the avoidance notch.

[0013] In some embodiments, the rail support assembly further includes idlers, which are respectively disposed on two placement platforms for placing 100-meter rails.

[0014] In some embodiments, the rail support assembly further includes a fastening frame, which is spaced apart on one side of the rotating frame and coaxially arranged with the rotating frame.

[0015] In some embodiments, the rail limiting assembly includes a plurality of fixing blocks arranged in a certain pattern on one side of the rail support assembly, and each fixing block has a limiting plate on both sides of its top, and the gap between two limiting plates is used to limit the rail from shifting.

[0016] In some embodiments, the support and fixing module further includes a rail spacing assembly, which is disposed on top of the rail support assembly on the outer side of the first transport vehicle, for limiting lateral movement of the rails.

[0017] In some embodiments, the rail spacing assembly includes a mounting base and spacers. The two ends of the mounting base are fixed to the support frame and the rotating frame, respectively. One end of each of the spacers is fixed to the side of the mounting base facing the rail, and the other end of each of the spacers extends between each pair of adjacent rails.

[0018] Compared with the prior art, the beneficial effects of this utility model mainly include:

[0019] This utility model provides a high-speed rail transport vehicle for 100-meter sections of rail. By installing support and limiting modules on the transport vehicles at both ends of the vehicle body, and by providing rail limiting components on both sides of the rail support components within these modules, and further by installing support and limiting modules on the remaining transport vehicles, where rail limiting components are located on one side of the rail support components, this design effectively limits the lateral movement of the 100-meter rails placed on the vehicle body. This prevents rails from detaching when the transport vehicle turns on the high-speed rail line, thus improving safety. This design meets the requirements for high-speed travel and turning on high-speed rail lines, ensuring the rails are firmly locked and unlikely to detach, thereby guaranteeing the safety performance of the rail transport vehicle.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] This utility model addresses the technical problem that existing 100-meter rail transport vehicles cannot meet the operational requirements of high-speed railway lines, and that forced use could easily lead to safety accidents. It proposes a new 100-meter rail transport vehicle for high-speed railways.

[0035] like Figure 1-3 As shown, this utility model relates to a high-speed rail 100-meter rail transport vehicle, including a vehicle body 100 and a support and limiting module 200. The support and limiting module 200 is disposed on the vehicle body 100 and is used to support and laterally limit the 100-meter rail placed on the vehicle body 100.

[0036] The main body 100 of the train set includes a plurality of transport vehicles, a locking vehicle and a plurality of transport vehicles connected in sequence. The support and limiting module 200 is disposed on the transport vehicle and includes at least one rail support component 210 and at least one rail limiting component 220. The support and limiting modules 200 located at both ends of the main body 100 of the train set have the rail limiting component 220 disposed on both sides of the rail support component 210. The support and limiting modules 200 on the other transport vehicles have the rail limiting component 220 disposed on one side of the rail support component 210.

[0037] The high-speed rail transport vehicle provided by this utility model has support and limiting modules 200 installed on the transport vehicles at both ends of the main body 100 of the vehicle. Each support and limiting module 200 has rail limiting components 220 on both sides of the rail support component 210. Additionally, in the support and limiting modules installed on the remaining transport vehicles, a rail limiting component 220 is installed on one side of the rail support component 210. This configuration effectively limits the lateral movement of the 100-meter rail placed on the main body 100 of the vehicle, preventing rail detachment when the transport vehicle turns on the high-speed rail line, thus improving safety. This meets the requirements for high-speed travel and turning on high-speed rail lines, ensuring the rail is firmly locked and not easily detached, thereby guaranteeing the safety performance of the rail transport vehicle.

[0038] In one embodiment, the transport vehicle includes a first transport vehicle located at both ends of the main body 100 of the vehicle group. The first transport vehicle is equipped with a first support and limiting module. The first support and limiting module includes a rail limiting component 220, two rail support components 210, and the rail limiting component 220 arranged sequentially along the length of the rail. The first transport vehicle at this location is the generator car.

[0039] In one embodiment, the transport vehicle includes a second transport vehicle located between the transport vehicles at both ends of the main body 100 and the locking vehicle. The second transport vehicle is equipped with a second support and limiting module 200, which includes a rail limiting component 220, two rail support components 210, or two rail support components 210 and a rail limiting component 220 arranged sequentially along the length of the rail. The second transport vehicle at this location is the transport vehicle itself.

[0040] That is, in this embodiment, the main body 100 of the train set includes 2 generator cars, 1 locking car, and 5 transport cars, and the formation sequence is: generator car + transport car. 3+ Locking vehicle + Transport vehicle 2+ Generator Car. The generator car is mainly used for safety protection during rail transportation, preventing the rails from moving out of the designated area during transport. The transport car is used for loading and transporting 100-meter sections of rail, providing lateral restraint during transport and reducing longitudinal resistance when traversing curves. The locking car is mainly used for locking the rails during transport, restricting longitudinal movement of the rails on the main body 100 of the train set, and adopts rail locks from the National Railway T11 long-rail car. The generator car, locking car, and transport car are all composed of a flatcar 110 and a base 120. The base 120 is set on the flatcar 110 and connected to the flatcar 110 through a pin 130, which facilitates assembly and disassembly without changing the original structure of the flatcar.

[0041] In one embodiment, the main body 100 of the train set also includes an arc plate 140. Multiple arc plates 140 are evenly arranged on both sides of the flatcar 110 for unloading rails on superelevated sections of the work line. In superelevated sections, the rails may come into contact with or collide with the car body, causing damage to the car body of the flatcar 110. However, by setting up the arc plate 140, the rails will come into contact with the arc plate 140 during rail unloading without colliding with the car body, thereby protecting the safety of the flatcar 110.

[0042] In one embodiment, the main body 100 of the train also includes a baffle 150, which is disposed on the generator car on the side of the generator set 400 near the support and fixing module 200, and is used to protect personnel from injury or equipment damage caused by the back-and-forth movement due to the failure of the rail fixing.

[0043] In one embodiment, the generator car is equipped with two rail support assemblies 210, and each rail support assembly 210 has a rail limiting assembly 220 on one side; the transport car is equipped with two rail support assemblies 210, and one of the rail support assemblies 210 has a rail limiting assembly 220 on one side; the locking car is equipped with only one rail support assembly 210. That is, the 100-meter rail transport vehicle group in this embodiment uses a two-point support method to transport the rails, so that the rails on the vehicle always have a support point, preventing the vehicle from being unbalanced.

[0044] In one embodiment, such as Figure 4 and Figure 5 As shown, the rail support assembly 210 includes a support frame 211, a rotating frame 212, and a placement platform 213. The placement platform 213 is arranged in two layers, with the lower layer fixed on the base 120. The two sides of the lower layer are fixedly connected to the support frame 211 and the rotating frame 212, respectively, and the rotating frame 212 is located on the side of the placement platform 213 near the central axis of the train body 100. One end of the upper layer is connected to the rotating frame 212, and the other end overlaps with the support frame 211.

[0045] In this embodiment, the placement platform 213 is set with only two layers, which lowers the center of gravity of the main body 100 of the train after the rails are placed, which helps the transport train meet the requirements of high-speed travel and turning on the high-speed rail line and prevents the rails from slipping.

[0046] Furthermore, the rotating frame 212 includes a rotating shaft 2121, a first sleeve 2122, a second sleeve 2123, and reinforcing ribs 2124. The bottom of the rotating shaft 2121 is rotatably connected to the lower placement platform. The first sleeve 2122 and the second sleeve 2123 are sequentially sleeved on the rotating shaft 2121 from bottom to top. The reinforcing ribs 2124 are evenly arranged on the outside of the first sleeve 2122. The second sleeve 2123 has a clearance notch. The upper placement platform is connected to the rotating shaft 2121 through the clearance notch.

[0047] In one embodiment, the rail support assembly 210 further includes idler rollers 214, which are respectively disposed on two placement platforms 213 for placing 100-meter rails.

[0048] In one embodiment, the rail support assembly 210 further includes a fastening frame 215, which is spaced apart on one side of the rotating frame 212 and coaxially arranged with the rotating frame 212.

[0049] In this embodiment, since the rotating frame 212 is located on the side of the placement platform 213 near the central axis of the flat car 110, the upper placement platform 213 rotates from both sides towards the middle. In order to ensure the strength of the rotating frame 212 in the middle, we set a first sleeve 2122 and a second sleeve 2123 and a reinforcing rib 2124 on the outside of the rotating shaft 2121, which can effectively strengthen its structure.

[0050] In this embodiment, the height of the rail support assembly 210 can be adjusted by setting a pad at the bottom. The adjustable height range is 50mm higher than the original height to meet the vehicle selection requirements.

[0051] In one embodiment, such as Figure 6 As shown, the rail limiting component 220 includes a plurality of fixing blocks 221 arranged in a certain pattern on one side of the rail support component 210. Specifically, they are arranged according to their distance from the rail support component 210. Each fixing block 221 has a limiting plate 222 on both sides of its top. The gap between two limiting plates 222 is used to limit the rail from shifting.

[0052] In this embodiment, the rail limiting component 220 is installed on the transport vehicle by setting one rail fixing component 220 every other rail support component 210. Since there are two rail support components 210 on the transport vehicle, one end of the rail placed on the transport vehicle is fixed by the rail limiting component 220, while the other end is in a free state. This satisfies both the high-speed operation of the high-speed rail line and the turning requirement of a minimum curve radius of 600m, effectively reducing the bending stress of the rail when crossing curves. The rail limiting component 220 is installed on one side of each rail support component 210 on the generator car. This is because the generator car is located at both ends of the main body 100 of the train set, thus this embodiment can effectively fix the rail at both ends. The rail limiting component 220 is not installed on the locking car because the locking car already has a locking component, which is a locking frame for existing 100-meter transport rails, such as a double-row lock.

[0053] In one embodiment, in order to better fix the rails at both ends of the main body 100 of the train, the support limiting module 200 further includes a rail spacing component 230, which is disposed on the top of the rail support component 210 on the outer side of the generator car, and is used to restrict the lateral movement of the rails.

[0054] In one embodiment, such as Figure 7 As shown, the rail spacing assembly 230 includes a mounting base 231 and spacers 232. The two ends of the mounting base 231 are fixed to the support frame 211 and the rotating frame 212, respectively. One end of each spacer 232 is fixed to the side of the mounting base 231 facing the rail, and the other end of each spacer 232 extends between each two adjacent rails. In this embodiment, the rail spacing assembly 230 can prevent the rail from overturning in superelevation sections.

[0055] In one embodiment, the rail transport vehicle group further includes rail hoisting modules 300, with multiple rail hoisting modules 300 respectively disposed in the middle of the generator car, the transport car, and the locking car. Rail support components 210 are disposed on both sides of the rail hoisting modules 300. That is, rail hoisting modules 300 are disposed in the middle of the generator car, the transport car, and the locking car, with two rail support components 210 on the generator car and the transport car respectively disposed on both sides of the rail hoisting module 300, and the rail support components 210 and locking components on the locking car respectively disposed on both sides of the rail hoisting module 300.

[0056] It is understood that the rail hoisting module 300 can be any structural form capable of hoisting rails in the art, such as a hoisting frame, a crossbeam and an electric hoist. The hoisting frame is installed in the middle of the transport vehicle, the locking vehicle and the generator vehicle, the crossbeam is installed on the hoisting frame, and the electric hoist is installed on the crossbeam for hoisting rails.

[0057] In summary, this utility model provides a high-speed rail 100-meter rail transport vehicle group, which can load, hoist, unload and transport rails on high-speed rail lines, and can also operate on conventional railways, with a higher level of safety.

[0058] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
