Description

Technical Field

[0001] This utility model relates to rail trains, specifically to a mounting bracket for a rail train steering sensor. Background Technology

[0002] The causes of wheelset failures in rail trains are complex and varied, mainly including material fatigue, wear, thermal damage, corrosion, manufacturing defects, improper maintenance, overload, environmental factors, design problems, and human factors. Real-time monitoring of train operation status and accurate prediction of axle and bearing failures require the integration of advanced sensing technology, data analysis algorithms, and intelligent systems. Real-time monitoring of data such as axle temperature is crucial for promptly detecting potential hot axle hazards and preventing axle combustion accidents, ensuring safe train operation.

[0003] The sensor detection required for train bogies faces multiple technical challenges. First, the limited space around the axle boxes makes it difficult to install a sufficient number of sensors, and the high-voltage environment poses significant safety hazards to the power supply leads of wired sensors. Second, the severe vibrations during train operation, especially continuous low-frequency vibrations, severely test the sensors and their mounting brackets. Prolonged vibration can cause the mounting brackets to break, damaging expensive electronic components, and may even cause the devices to detach and fall onto the tracks, increasing the risk of train derailment and causing serious social and economic consequences. Furthermore, signal transmission from various systems within the train, the use of wireless devices by passengers, and the shielding effect of the metal materials on the mounting brackets all interfere with the data transmission of the wireless monitoring system. These issues have consistently been technical difficulties in bogie and axle box detection, and have significantly restricted the research and application of sensors on railcars.

[0004] Currently, most sensor mounting brackets have significant design flaws, failing to provide a safe and stable working environment for the sensors and easily causing the brackets to sway due to vibration. Therefore, there is an urgent need for a mounting bracket device specifically designed for bogie sensors, providing a reliable mounting foundation for the electronic components required for train axle box safety monitoring. Utility Model Content

[0005] This invention provides a mounting bracket for a rail train steering sensor. The mounting bracket is fixedly installed on a vertical frame at the top of the rail train bogie. The rail train steering sensor is mounted on the mounting bracket, and the rail train steering sensor includes a sensor body and at least one cable.

[0006] The mounting bracket is provided with an L-shaped metal frame cut and formed in one piece. The L-shaped metal frame has a horizontal base plate and a back plate vertically located at one end of the base plate.

[0007] The base plate is provided with multiple sensor mounting holes. Sensor mounting bolts pass through the sensor mounting holes from bottom to top and are threaded to the sensor body. An oval wire passage groove is provided at one end of the base plate away from the back plate. The cable passes through the wire passage groove downwards.

[0008] The back plate has four main unit mounting holes distributed at the four corners. A row of gasket mounting holes is provided on both the left and right sides of the back plate. Multiple bracket mounting bolts pass through the main unit mounting holes and the gasket mounting holes respectively and are connected to the vertical frame to fix the mounting bracket.

[0009] Furthermore, the sensor mounting holes are arranged in a 3-row × 2-column array to form a 6-counterhole structure.

[0010] Furthermore, the base plate is provided with oval cable tie holes on both sides, and cable ties are connected between the cable tie holes on both sides to fix the cables at the bottom of the base plate.

[0011] Furthermore, the base plate and the vertical frame are provided with anti-fall holes, and steel wire ropes or chains are connected between the anti-fall holes of the base plate and the vertical frame.

[0012] Furthermore, a shim for leveling the back plate is provided between the back plate and the vertical frame, and the shim is fitted onto the bracket mounting bolts.

[0013] Furthermore, the edges of both the cable tray and the mounting bracket are rounded chamfers.

[0014] The connection between the base plate and the back plate is provided with a rounded chamfer.

[0015] Furthermore, two weight-reducing waist-shaped holes are provided within the area enclosed by the main unit mounting holes.

[0016] The advantages of this utility model are:

[0017] 1) The L-shaped metal frame, cut and formed in one piece, ensures the stability of the mounting bracket and makes full use of the limited space at the top of the bogie to achieve compact installation of the sensor.

[0018] 2) The main unit mounting holes and gasket mounting holes distributed on the back plate enable the mounting bracket to be firmly fixed on the vertical frame, effectively resisting the severe vibration during train operation and ensuring the long-term stable operation of the sensor.

[0019] 3) The bottom plate has an oval-shaped cable tray at the end away from the back plate. The sensor cable can pass through the cable tray and be fixed at the bottom of the bracket, avoiding the problem of messy cables. Cable ties can also be used to fix the cable, ensuring the neatness and safety of the line.

[0020] 3) A steel wire rope or chain is installed between the mounting bracket and the vertical frame support to prevent falling. When the bolts fall due to vibration, the steel wire rope or chain can hold the mounting bracket to prevent it from falling. Attached Figure Description

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0031] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0032] This utility model provides a mounting bracket for a rail train steering sensor. The mounting bracket is fixedly installed on a vertical frame 1 at the top of the rail train bogie. The rail train steering sensor is installed on the mounting bracket 2. The rail train steering sensor includes a sensor body 11 and at least one cable 12.

[0033] Mounting bracket 2 features an L-shaped metal frame formed by one-piece cutting. The L-shaped metal frame has a horizontal base plate 21 and a back plate 22 perpendicularly located at one end of the base plate 21. The sensor mounting bracket 2 is machined from angle iron, ensuring the overall structure remains intact. The one-piece forming method eliminates structural breaks. Compared to existing sensor mounting brackets, this eliminates welding and bending processes, maximizing the integrity of the bracket and effectively preventing mechanical fatigue damage caused by welding and bending of reinforcing ribs. Eliminating bending processes avoids damage to the internal structure of the material, and the one-piece forming eliminates stress concentration points. To improve the corrosion resistance of the mounting bracket, the L-shaped metal frame can be galvanized to enhance its corrosion resistance and prevent damage due to corrosion during long-term use, thus ensuring the stability and reliability of the mounting bracket.

[0034] The base plate 21 is provided with multiple sensor mounting holes 8. The sensor mounting bolts pass through the sensor mounting holes 8 from bottom to top and are threaded to the sensor body 11. At the end of the base plate 21 away from the back plate 22, there is an oval wire passage groove 9, through which the cable 12 passes downward.

[0035] The back plate 22 has four main unit mounting holes 13 distributed at the four corners. A row of gasket mounting holes 5 is provided on both the left and right sides of the back plate 22. Multiple bracket mounting bolts 3 pass through the main unit mounting holes 13 and the gasket mounting holes 5, respectively, and are connected to the vertical frame 1 to fix the mounting bracket. This utility model patent addresses the significant low-frequency vibrations that occur during the operation of rail trains by using a four-point bolt fixing method, which is more in line with mechanical properties. While ensuring strength, it reduces the weight of the connecting parts, thus reducing the additional load on the bogie. The material is hard and has a long service life, which is more conducive to the normal operation of the sensor in severe vibration environments.

[0036] In an optional embodiment, the sensor mounting holes 8 are arranged in a 3-row × 2-column array to form a 6-counterhole structure, providing fixation for the railcar steering sensor.

[0037] In an optional embodiment, the base plate 21 is further provided with oval cable tie holes 10 on both sides, and cable ties are connected between the cable tie holes 10 on both sides to secure the cable 12 at the bottom of the base plate 21, thereby preventing the cable 12 from being damaged by pulling or vibration during installation and use. The use of cable ties not only provides additional fixing force, but also makes cable management neater and facilitates later maintenance and inspection.

[0038] In an optional embodiment, anti-fall holes 7 are provided on both sides of the base plate 21 and the vertical frame 1. A wire rope or chain is connected between the anti-fall holes 7 of the base plate 21 and the vertical frame 1. One end of the wire rope or chain is fixedly connected to a spring buckle, and the other end is connected to a fixing ring. Connecting the spring buckle and the fixing ring makes the two ends of the wire rope or chain connected together to form a closed loop, thereby flexibly connecting the mounting bracket 2 and the vertical frame 1. The significance of the anti-fall holes 7 is that when the mounting bolts loosen and fall due to the vibration of the rail train, the wire rope or chain can hold the mounting bracket 2, preventing the mounting bracket 2 from falling and causing an accident.

[0039] In an optional embodiment, if the back plate 22 cannot form a good fit with the vertical frame 1, a shim can be added between the back plate 22 and the vertical frame 1 for leveling the back plate 22. The shim is fitted onto the bracket mounting bolt 3, eliminating the gap between the back plate 22 and the vertical frame 1, ensuring a tight fit between the back plate 22 and the vertical frame 1, thereby improving the stability of the mounting bracket. The thickness of the shim can be selected according to the actual situation to ensure that the gap between the back plate 22 and the vertical frame 1 is completely eliminated.

[0040] In an optional embodiment, to improve the seismic performance of the mounting bracket, a shock-absorbing pad can be added between the base plate 21 and the vertical frame 1. The shock-absorbing pad can be made of elastic materials such as rubber and silicone, which have good seismic resistance, buffering and sound insulation effects, and can effectively reduce the impact of vibrations generated during train operation on the sensor and its mounting bracket, thus extending the service life of the sensor.

[0041] Furthermore, the mounting bracket of this utility model has advantages such as simple structure, convenient installation, and easy maintenance. The overall structure of the mounting bracket is compact, occupies little space, and can be easily installed on the top of the bogie of a railcar. At the same time, the connection between the various components of the mounting bracket is simple, easy to disassemble and replace, and reduces maintenance costs.

[0042] In an optional embodiment, the edges of the relief groove 12 and the mounting bracket are both rounded chamfers. The relief groove 12 has smooth edges, which can effectively prevent the cable from being scratched or worn during installation and use, thereby improving the service life of the cable. The mounting bracket has smooth edges, which can prevent scratches on installation workers.

[0043] The connection between the base plate 21 and the back plate 22 is provided with an inwardly rounded chamfer 6, which makes the base plate structure of the mounting bracket more compact and reduces the space occupied by the mounting bracket on the bogie.

[0044] In an optional embodiment, two vertical weight-reducing waist-shaped holes 4 are provided in the area enclosed by the main unit mounting hole 13. The weight-reducing waist-shaped holes 4 are provided to reduce the weight of the support while having better resistance to vibrations generated during train operation, thus reducing structural fatigue caused by long-term vibration.
