Abstract

The utility model discloses an antenna installation device, belonging to the field of design of railway vehicle structures and aiming at solving the problem of cracking of welding joints and connecting members, possibly existing in both an independent antenna installation device and an integral antenna installation device in the travelling process of a vehicle. The antenna installation device comprises brackets I and at least one bracket II, wherein the brackets I are fixed at two ends of a framework; the brackets II are used for installing antennas; installing holes of the brackets I are connected with installing holes of the brackets II through steel pipes; the antennas are arranged at the lower parts of the brackets II; and the brackets I and the steel pipes are connected through elastic sleeves. By means of the antenna installation device, the fatigue stress caused by railway distortion and end part deformation of the framework is effectively relieved, the installation heights of the antennas are adjustable, and the distance between the antennas and the railway surface is always kept at a required height value. The antenna installation device disclosed by the utility model is mainly suitable for steering racks of railway vehicles.

Description

A kind of antenna mounting device

Technical field

The utility model relates to a kind of antenna mounting device, belongs to rail vehicle structural design field, is mainly used on the rail vehicle truck.

Background technology

It is free-standing antenna mounting device that existing subway ATC antenna is installed a kind of typical structure, promptly an antenna mounting device respectively is set, and does not have bindiny mechanism between two erecting devices, be cantilever beam structure at the two ends, the left and right sides of framework, generally hang on the end of bogie, see shown in Figure 1.This device is subjected to coming from vertical, the vertical and horizontal vibration that bogie transmits in the vehicle operating process, under the effect of fatigue load, causes welded weld seam to crack, and destroys.

Another kind of typical structure is the integral type antenna mounting device, promptly on the basis of free-standing antenna mounting device, the antenna mounting device at two ends, the left and right sides is linked together by long steel pipe, see shown in Figure 2, design has been avoided because the weld cracking that cantilever beam structure causes like this, but this structure mostly is the Welding Structure of steel plate or steel plate and steel pipe, inside configuration is for being rigidly connected, when track distortion and the distortion of framework end, easily generation stress is concentrated between steel pipe and connecting plate crackle occurs, thereby can't finish the reliable installation of antenna.

Summary of the invention

In order to overcome weld seam and connector all may appear in existing free-standing antenna mounting device and integral type antenna mounting device in the vehicle operating process cracking problem, the utility model aims to provide a kind of antenna mounting device, this device can avoid additional fatigue stress to the welded influence of antenna mounting device, reliability height effectively.

To achieve these goals, the technical scheme that the utility model adopted is: described antenna mounting device, comprise support one and at least one support that is used to fix up an aerial wire two of being fixed on the framework two ends, the installing hole of described support one is connected by steel pipe with the installing hole of support two, and described antenna is installed in the bottom of support two; Be characterized in, be connected by spring-backed quill between described support one and the steel pipe.

Further, described support two is two, and two antennas are contained in the bottom of two supports two respectively, by long steel pipe mechanism is linked to be an integral body, two antennas at framework two ends are installed respectively, the weld cracking of having avoided cantilever beam structure to cause, and reduced the vertical vibration of antenna mounting device.

By on the basis of integral type antenna mounting device structure, the caoutchouc elasticity sleeve pipe is installed to flexibly connect, utilize the strain of rubber to eliminate the additional stress that curved in tracks and framework distortion are caused, can reduce welded fatigue stress, the useful life of improving structure greatly effectively like this.The performance of described spring-backed quill can design according to curved in tracks degree, framework deflection and corresponding fatigue load, draws the rigidity value that is complementary, and makes spring-backed quill bring into play the effect of its buffer shock-absorbing to greatest extent.

The bottom of described support two is connected with bent plate, and described antenna is fixed on the bottom of bent plate.Further,,, guarantee that the distance of antenna and rail level remains at the height value that needs, be provided with between the top of described support two and bent plate and highly regulate backing plate with the wearing and tearing of compensation wheel in order to regulate the setting height(from bottom) of antenna.

Compared with prior art, the beneficial effects of the utility model are: 1) alleviated the fatigue stress owing to track twists and the distortion of framework end causes effectively.

2) by long steel pipe mechanism is linked to be an integral body, two antennas at framework two ends are installed respectively, the weld cracking of having avoided cantilever beam structure to cause, and reduced the vertical vibration of antenna mounting device.

3) setting height(from bottom) of adjustable antenna with the wearing and tearing of compensation wheel, has guaranteed that the distance of antenna and rail level remains at the height value that needs.
