[0002] The beacon antenna is an important part of the train communication system. It is responsible for receiving and sending signals to ensure the safe operation of the train. It is usually installed at the bottom of the train to communicate effectively with the ground base station. When installing, leave a certain amount of space under the antenna to reduce the interference of ground obstacles on the signal and ensure smooth airflow.

[0003] In order to improve the stability of the beacon antenna, it is necessary to consider the impact of the airflow generated by the train when it is running. Therefore, the installation design needs to take into account aerodynamics to reduce wind resistance and wind vibration. At the same time, the stability of the grounding braid is also crucial.

[0025] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0026] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0027] Reference Figure 1The present embodiment provides a beacon antenna connection device, including a fixing component 1, used to connect the beacon antenna to the train chassis; the fixing component 1 includes a stabilizing plate 11 fixedly arranged on both sides of the beacon antenna along the length direction of the train; and a shock absorbing component 2 is arranged between the beacon antenna and the train chassis, one side of the shock absorbing component 2 is connected to the stabilizing plate 11, and the other side is connected to the train chassis.

[0028] like Figure 1 , the beacon antenna is marked as X and the train underframe is marked as J.

[0029] The stabilizing plate 11 is fixed to both sides of the beacon antenna by bolts. The stabilizing plate 11 is preferably arranged on both sides parallel to the front and rear of the train, so as to play a certain role in blocking the train wind.

[0030] The train will generate various vibrations during operation, which may be transmitted to the beacon antenna, affecting its structural integrity and signal stability; the shock absorbing component 2 can reduce the impact of the vibration on the antenna.

[0031] As an optional embodiment, the stabilizing plate 11 is divided into a first section 111, a second section 112 and a third section 113 in sequence from the train chassis to the beacon antenna. The first section 111 is bent into an arc in a direction away from the beacon antenna, and an angle formed between the first section 111 and the second section 112 is greater than 90°.

[0032] like Figure 5 As shown, the stabilizing plate 11 is bent to form a first section 111, a second section 112 and a third section 113, thereby increasing the structural strength of the stabilizing plate 11. The stabilizing plate 11 is symmetrically arranged on both sides of the beacon antenna. The specific bending direction of the first section 111 is as follows: Figure 5 As shown, the outer angle formed between the first section 111 and the second section 112 needs to be greater than 90°, so that the wind from the front to the rear of the vehicle can be guided downward along the streamline when passing through the arc of the first section 111. Since related components are connected between the beacon antenna and the train chassis, not just the shock absorbing component 2, the direct impact of the wind on the connection of these components can be reduced by guiding the wind direction, thereby ensuring the stability of the connection and avoiding the generation of eddy currents.

[0033] As an optional embodiment, the third section 113 is bent toward the beacon antenna, and the angle formed between the second section 112 and the third section 113 is greater than or equal to 90°; and the tail end of the second section 112 is located directly below the beacon antenna.

[0034] The inner angle formed between the second section 112 and the third section 113 needs to be greater than or equal to 90°. In this case, the side close to the beacon antenna is the inner side, and the side relatively far from the beacon antenna is the outer side. When the angle between the second section 112 and the third section 113 is greater than or equal to 90°, the wind blowing toward the third section 113 will be guided downward along the curve. Considering that the beacon antenna will maintain a certain distance from the ground during actual installation, guiding the wind to the bottom of the beacon antenna can make the flow more unobstructed and, to a certain extent, avoid the connection between components. After the second section 112 is bent, its tail end can also be located directly below the beacon antenna, which can further play a certain supporting role, thereby supporting the beacon antenna.

[0035] The first section 111 , the second section 112 and the third section 113 are integrally formed to form the stabilizing plate 11 . The stability of the overall structure can be increased by bending the first section 111 and the third section 113 .

[0036] As an optional embodiment, the shock absorbing assembly 2 includes a spiral steel wire rope 21, two inner clamping plates 211 are symmetrically provided inside the spiral steel wire rope 21, and two outer clamping plates 212 are symmetrically provided outside the spiral steel wire rope 21; the inner clamping plates 211 and the outer clamping plates 212 are connected to each other correspondingly.

[0037] like Figure 1 , Figure 2 As shown, two spiral steel wire ropes 21 are symmetrically arranged, and the inner clamping plate 211 and the outer clamping plate 212 are connected one by one. The shock absorbing assembly 2 can reduce the influence of the train running vibration.

[0038] As an optional embodiment, a plurality of openings 213 are further provided on the inner clamping plate 211 and the outer clamping plate 212 ; and the openings 213 are used to clamp the spiral steel wire rope 21 .

[0039] like Figure 2 As shown, the constriction openings 213 between the inner clamping plates 211 and the outer clamping plates 212 correspond one to one, and the constriction openings 213 can clamp a single steel wire rope; the inner clamping plates 211 and the outer clamping plates 212 are preferably connected by bolts.

[0040] As an optional embodiment, one of the outer clamping plates 212 outside the spiral steel wire rope 21 is connected to the second section 112 .

[0041] As an optional embodiment, the outer wall of another outer clamping plate 212 outside the spiral steel wire rope 21 is connected to the plate frame 12; the plate frame 12 and the train chassis are fixedly connected by screws and nuts.

[0042] The plate frame 12 is connected between the two outer clamping plates 212, and the plate frame 12 is fixedly connected to the train underframe.

[0043] As an optional embodiment, a grounding braid 3 is connected between the beacon antenna and the train, both ends of the grounding braid 3 are connected to the beacon antenna or the train by bolts, and two gaskets 31 are arranged between the grounding braid 3 and the bolts.

[0044] Generally, a grounding braid 3 is connected between the train and the beacon antenna. The grounding braid 3 helps to reduce the electromagnetic interference generated by the beacon antenna when receiving and sending signals, and maintain the stability of the system.

[0045] As an optional embodiment, one side of the two gaskets 31 is configured to be tooth-shaped, and the two gaskets 31 are engaged with each other.

[0046] Two washers 31 are added between the bolt and the grounding braid 3 , and the contact surfaces of the two washers 31 are configured to be tooth-shaped and mesh with each other. This configuration can help to improve the connection stability of the grounding braid 3 .

[0047] Reference Figure 1 to Figure 6 This embodiment provides an installation method, including installing a beacon antenna at the center of a train bogie, and equipping each end of the train with a beacon antenna; positioning and installing a stabilizing plate at a predetermined position of the beacon antenna, and connecting the stabilizing plate to a shock absorbing assembly; connecting the train chassis to the shock absorbing assembly through a plate frame; after fixing the beacon antenna, completing the connection of the grounding pigtail and confirming that the connection is firm; after the installation is completed, performing a signal test to ensure that the beacon antenna is working properly.

[0048] like Figure 6 Shown is a diagram of the connection position between the beacon connection and the train bogie.

[0049] Installing the beacon antenna at the center of the train bogie, with one at each end, can help ensure uniformity and stability of signal coverage; after the connection is completed, signal debugging is required to ensure normal operation.

[0050] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
