Description

Technical Field

[0001] The invention relates to the technical field of transponder installation, and in particular to a mounting bracket suitable for large-size transponders. Background Art

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

[0003] At present, most of the balises adapted to 350km / h high-speed trains are standard-sized balises with an effective reference area of ​​200mm×390mm. With the development of 400km / h high-speed trains, standard-sized balises can only use short-format messages at this speed. In the CR450 higher-speed balise transmission system adaptability test conducted in 2022, the CR400BF-J comprehensive inspection vehicle was tested on the Puzheng section of the Jinan-Zhengzhou High-speed Railway. When the train speed was increased to 400km / h, the average horizontal range of the effective message data of the ground balise was about 2059bit, and the minimum was 1947bit, which did not meet the data volume of two complete messages. Its data safety margin was reduced compared to when running at speeds below 350km / h.

[0004] The TB / T 3485-2017 "Technical Conditions for Balise Transmission Systems" issued by the National Railway Administration in 2017 stipulates that the effective reference area of ​​a large-size balise is 358mm×488mm, which can be compatible with long-format or short-format messages at speeds of 350km / h to 500km / h. According to the standard, the horizontal range of a large-size balise along the line direction can reach 800mm to 1200mm. When the train runs at a speed of 400km / h, it can receive 3 to 5 complete message data, which is equivalent to the information transmission of a standard-size balise at a speed of 250km / h, and can fully meet the application requirements of a speed of 400km / h.

[0005] The installation of the transponder has strict installation requirements to ensure its safe and stable operation during its life cycle. In order to meet the driving safety of high-speed trains with a speed of 400km / h, a large-size transponder with an enlarged antenna range has been developed to increase the range of the transponder. Due to the increase in the size of the transponder, the mounting bracket of the existing standard-size transponder can no longer meet the installation and fixation requirements of the large-size transponder.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The purpose of the present invention is to provide a mounting bracket suitable for large-size transponders, which has a simple structure, can well meet the installation requirements of large-size transponders, can ensure the stability of the large-size transponders after installation, and thus solve the above-mentioned technical problems existing in the prior art.

[0008] The objective of the present invention is achieved through the following technical solutions:

[0009] A mounting bracket suitable for a large-size transponder, comprising:

[0010] two lower pressure plates, two enlarged brackets, an epoxy resin upper pad, a lower pad, two epoxy resin mounting pads, multiple bottom bolt assemblies, multiple top bolt assemblies, multiple bolts and two pad bolt assemblies; wherein,

[0011] The two lower pressing plates are arranged in parallel;

[0012] The bottom end of each enlarged bracket is fixed to a lower pressure plate by multiple sets of bottom bolt assemblies;

[0014] The middle position of the bottom of the epoxy resin upper pad is connected to the lower pad by a plurality of bolts;

[0015] A plurality of supporting and mounting holes are arranged on the top surface of the epoxy resin upper pad.

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

[0017] Compared with the prior art, the mounting bracket for large-size transponders provided by the present invention has the following beneficial effects:

[0018] By adopting two enlarged brackets, two lower pressure plates, an epoxy resin upper pad and a lower pad, and fixing the various parts through multiple groups of bottom bolt assemblies, multiple groups of top bolt assemblies and multiple bolts, the size of the mounting bracket is increased, which can adapt to the installation and fixation of large-size transponders; by adding the epoxy resin upper pad and the epoxy resin mounting pad, the stable placement of the large-size transponder can be guaranteed and the anti-interference ability is improved; by using multiple groups of bottom bolt assemblies, multiple groups of top bolt assemblies and multiple bolts, the stability of the installation can be guaranteed; by setting up two lower pressure plates, the stability and anti-interference ability of the large-size transponder can be guaranteed.

Each epoxy resin mounting pad 4 is provided with a mounting hole for mounting a large-size transponder.

[0046] See also Figure 6Preferably, in the above-mentioned mounting bracket, the epoxy resin upper pad 3 has a length of 500 mm, a width of 430 mm, and a thickness of 10-20 mm. The epoxy resin upper pad 3 of this size matches the large-sized transponder, can well support the installation of the large-sized transponder, and can improve the anti-interference ability of the large-sized transponder.

[0047] Preferably, in the above-mentioned mounting bracket, the multiple groups of bottom bolt assemblies have the same composition, and each group of bottom bolt assemblies is composed of a first hexagonal head bolt 6, a square washer 13, an anti-vibration washer 14 and an anti-rotation washer 15.
