Problems solved by technology
As the speed of trains increases, especially when the speed of high-speed trains exceeds 200Km / h, the original thread fastening method can no longer meet the needs of roof installation.
Moreover, the devices used to install satellite antennas in the prior art do not take into account the impact of wind resistance and braking on antennas and roof steel structures during the operation of high-speed rail transit vehicles.

Embodiment Construction
[0013] In order to make the technical solutions and advantages of the present utility model more clear, the technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model:
[0014] Such as figure 1 and image 3 The shown mounting device for the vehicle-mounted satellite antenna in rail transit includes a mounting clip 2 and a mounting frame body 8 , and the mounting clip 2 clamps the mounting frame body 8 . The installation clip 2 is threadedly connected with the satellite antenna. The mounting bracket body 8 is provided with a plurality of buffer assemblies 81 for buffering the movement of the vehicle body. The buffer assemblies 81 include buffer I1 and buffer II3 with the same internal structure. The way is respectively arranged on the front end and the rear end of the mounting frame body 8.
[0015] Further, such as figure 2 As s...

The invention discloses a rail transit vehicle-mounted satellite antenna installation device, which comprises a mounting clip, the mounting clip is connected with the satellite antenna, the mounting clip is connected with a mounting frame, and the mounting frame is provided with a plurality of The buffer assembly is used to buffer the movement of the vehicle body. The buffer assembly includes the buffer I and the buffer II with the same internal structure. end. This device adopts the clip-type connection method to clamp the installation frame body on the installation clip, and the satellite antenna is threaded with the installation clip. Using the clip-type connection, the bolts are changed from the main tangential force in the traditional mode to the size The average tangential force and axial force improve the practical life and fastening strength of bolts, and effectively alleviate the impact of wind resistance and braking on the antenna and roof steel structure of high-speed rail transit vehicles during operation.
Description
technical field [0001] The utility model relates to the installation field of rail traffic vehicle-mounted satellite antennas, in particular to a rail traffic vehicle-mounted satellite antenna installation device. Background technique [0002] The satellite antenna is used to reflect the satellite signal to the feed source and high frequency head at the focal point, it collects the signal from the satellite and performs impurity processing on the signal. At present, the known vehicle-mounted satellite antenna is installed on the steel structure at the top of the train roof, and is fastened with threads, and this connection mode is on the steel structure of the passenger vehicle. As the speed of the train increases, especially when the speed of the high-speed train exceeds 200Km / h, the original thread fastening method can no longer meet the needs of the roof installation. Moreover, the device for installing satellite antennas in the prior art does not take into account the i...
