Description

Technical Field

[0001] The utility model relates to the technical field of substitute bogie design, in particular to a substitute bogie suitable for intercity trains. Background Art

[0002] Intercity trains, also known as intercity rail services, are passenger trains that run between adjacent major cities or city clusters. They typically cover a relatively short distance, have a short journey time, and pass through fewer cities. Intercity trains are short- and medium-distance passenger trains that serve only a few specific cities, primarily serving to strengthen connections between nearby cities and facilitate cross-city travel and cultural exchange within surrounding areas. While intercity trains are not as widely used as long-distance trains, with the rapid development of numerous city clusters in my country and the large-scale construction of numerous intercity railways, their importance in rail transportation is steadily increasing.

[0003] Taking the 160km intercity train as an example, as an important means of transportation connecting major cities and urban agglomerations, the 160km intercity train is of great significance for promoting regional economic development and personnel mobility. As a carrier for transporting or temporarily storing vehicle bodies during vehicle production, substitute bogies have become indispensable mechanical components for rail transit vehicle manufacturers in the process of vehicle assembly and continuous vehicle operation. Most of the substitute bogies commonly used in the existing technology are suitable for traditional Type A / Type B subway vehicles or locomotives. At present, the following measures can only be taken to operate the 160km intercity train:

[0004] 1. The 160km intercity train (each section weighs about 50 tons) uses the "substitute light-load bogies" used in traditional subway trains (each section weighs 20 to 30 tons) for turnover, which is obviously unsafe.

[0005] 2. The "substitute heavy-duty bogie" used for locomotives is used for operation. Due to structural differences, it cannot pass through curved track lines and can only circulate on straight lines, which is obviously inconvenient.

[0006] 3. The existing substitute bogies have no fixed connection to the vehicle body, which is obviously unsafe.

[0007] 4. Lifting the vehicle onto a flatbed trailer for transportation is obviously time-consuming, labor-intensive, and unsafe.

[0008] As can be seen, with the increasing popularity of 160km intercity EMUs, there is an urgent need to design an alternative bogie that matches the 160km intercity vehicle underframe structure, thereby achieving simple, efficient, and safe vehicle assembly and turnover operations. Utility Model Content

[0009] In response to the above technical problems, a replacement bogie suitable for intercity trains is provided. The technical means adopted by the utility model are as follows:

[0010] A substitute bogie suitable for intercity trains includes a supporting body, a rotating mechanism and a rotating beam. The bottom end of the supporting body is provided with multiple wheels. The rotating mechanism is installed above the supporting body. The rotating beam is connected above the rotating mechanism. The rotating beam is provided with a positioning hole connected to the intercity car body to be transported. The rotating mechanism can rotate relative to the supporting body.

[0011] Furthermore, the rotating mechanism includes a fixing portion and a rotating portion, and the fixing portion is mounted on a mounting seat of the supporting body by means of bolts.

[0012] Furthermore, the rotating part is a circular core disk, a rolling element is provided between the rotating part and the fixed part, and a rotating shaft for connecting to the crossbeam is provided on the upper surface of the circular core disk.

[0013] Furthermore, the outer diameter of the rotating part is smaller than the inner diameter of the fixing part, and the width of the supporting body is larger than the outer diameter of the fixing part.

[0014] Furthermore, there is one rotating shaft and it is arranged at the center of the circular core disk.

[0015] Furthermore, the rotating beam and the rotating shaft are mounted via bolts, and the fixing portion is connected to the mounting seat via a plurality of bolts arranged in a circumferential vertical direction.

[0016] Furthermore, the positioning hole is a positioning pin hole, and the rotating beam is connected to the vehicle body by bolts.

[0017] Furthermore, the left and right ends of the rotating beam are connected to the vehicle body, the width of the left and right ends of the rotating beam is greater than the width of the rotating beam body, and reinforcing rib structures are provided at the left and right ends of the rotating beam.

[0018] Furthermore, the supporting body is a frame, and its sides, ends and mounting seats are made of steel plates with a thickness of 20±10 mm. The frame formed by the sides, ends and mounting seats is a hollow structure.

[0019] Furthermore, a reinforcing rib device is provided at the bottom of the supporting body, and the reinforcing rib device includes a plurality of vertical plates arranged perpendicular to the bottom surface of the supporting body and a plurality of rib plates perpendicular to the vertical plates.

[0020] The utility model has the following advantages:

[0021] 1. This utility model is designed as a replacement bogie for intercity trains. After the car body is lowered onto the replacement bogie, a rotating mechanism enables the intercity train to navigate curved tracks. The rotating crossbeam of the replacement bogie is provided with locating pin holes at both ends, which are bolted to the car body, further improving safety.

[0022] 2. The utility model is suitable for setting a rotatable crossbeam structure on the substitute bogie of intercity trains. After the car body falls on the substitute bogie crossbeam, the crossbeam can rotate left and right, so the car body can pass through a curved line during its rotation on the track.

[0023] 3. This replacement bogie is fully compatible with the intercity train underframe structure. It allows for both vehicle movement and temporary storage along curved track lines. It also serves as a final assembly platform for fixed vehicle fixtures, enabling vehicle assembly and manufacturing, effectively reducing production costs. The replacement bogie eliminates the need to hoist the vehicle onto a flatbed trailer for transport, effectively improving turnover efficiency and saving production costs.
