Description

Technical Field

[0001] This utility model relates to the field of transponder installation technology, and in particular to a mounting bracket suitable for large-size transponders. Background Technology

[0002] A transponder is a device used to transmit information from the ground to a train. It is usually installed in the middle of the track and supported by a mounting bracket. It is a key ground device to ensure the safety of train operation.

[0003] Currently, most transponders adapted to 350km / h high-speed trains are standard-sized transponders with an effective reference area of ​​200mm × 390mm. However, with the development of 400km / h high-speed trains, at this speed, standard-sized transponders can only use short-format messages. In the 2022 CR450 transponder transmission system adaptability test under higher speed conditions, the CR400BF-J comprehensive test vehicle, during testing on the Puyang-Zhengzhou section of the Jinan-Zhengzhou High-Speed ​​Railway, showed that when the train speed increased to 400km / h, the average horizontal effective range of the ground transponder's message data was approximately 2059 bits, with a minimum of 1947 bits. This is insufficient for two complete messages, indicating a reduced data safety margin compared to operation at speeds below 350km / h.

[0004] The National Railway Administration's 2017 standard TB / T 3485-2017, "Technical Conditions for Transponder Transmission Systems," stipulates that the effective reference area of ​​a large-size transponder is 358mm × 488mm, and it can be compatible with both long and short format messages at speeds from 350km / h to 500km / h. Based on the standard, the horizontal effective range of a large-size transponder along the track direction can reach 800mm to 1200mm. When the train is running at 400km / h, it can receive 3 to 5 complete message data, which is equivalent to the information transmission capacity of a standard-size transponder at 250km / h, fully meeting the operational requirements at 400km / h.

[0005] The installation of transponders has stringent requirements to ensure their safe and stable operation throughout their life cycle. In order to meet the driving safety of high-speed trains with a speed of 400 km / h, a large-size transponder with an increased antenna range has been developed to increase the effective range of the transponder. Due to the increase in the size of the transponder, the existing standard-size transponder mounting brackets can no longer meet the installation and fixing requirements of the large-size transponder.

[0006] In view of the above, this utility model is hereby proposed. Summary of the Invention

[0007] The purpose of this utility model is to provide a mounting bracket suitable for large-size transponders. Its structure is simple, it can well meet the installation requirements of large-size transponders, and can ensure the stability of large-size transponders after installation, thereby solving the above-mentioned technical problems existing in the prior art.

[0008] The objective of this utility model is achieved through the following technical solution:

[0016] Two epoxy resin mounting pads are fixed to the support mounting holes on the top surface of the epoxy resin upper pad by two sets of pad bolt assemblies arranged in parallel and spaced apart. Each epoxy resin mounting pad is provided with mounting holes for mounting a large-size transponder.

[0017] Compared with the prior art, the mounting bracket for large-size transponders provided by this utility model has the following advantages:

[0018] The use of two enlarged brackets, along with two lower pressure plates and an epoxy resin upper and lower pad, along with multiple sets of bottom bolt assemblies, multiple sets of top bolt assemblies, and numerous bolts to secure each part, increases the size of the mounting bracket, making it suitable for installing and fixing large-sized transponders.
