Embodiment approach
[0024] As an embodiment of the present invention, a support member 22 is slidably installed in the cavity 19, and the support member 22 includes a fixed plate 23 and a fixed shaft 24; five fixed plates 23 are provided; One end of 23 is welded on the outer surface of the fixed shaft 24 and is distributed in five equal parts; the supporting member can be inserted into the cavity 19 to support the regular hexagonal compression body 18 . During work, by sliding and inserting the corresponding support piece 22 into the cavity 19 in the regular hexagonal pressure-resistant body 18, when the profile is subjected to external pressure, the internal support piece 22 can effectively support the cavity 19. Strong support is provided to ensure the support strength of the regular hexagonal compression body 18, prolong the overall service life of the regular hexagonal compression body 18, and further enhance the overall support strength and compressive capacity of the profile.

Abstract
The invention belongs to the technical field of railway accessories, concretely to an aluminum alloy profile. The aluminum alloy profile comprises a profile top plate, an antistatic coating, a supporting head, a pressure bearing rod, a fixing head, a first pressure bearing plate, a mounting head, a mounting groove, a connecting groove and a bearing base, the aluminum alloy profile for the high-speed rail is jointly composed of the profile top plate, the antistatic coating, a buffer cavity and a second pressure bearing plate, and the profile top plate is fixedly mounted at the top of the aluminum alloy profile for the high-speed rail. Through the antistatic coating arranged on the upper surface of the profile top plate, static electricity generated during friction of the base material can be effectively avoided; profile can be preveneted from being damaged, the arranged pressure bearing rods can be used for carrying out pressure-resistant support on the profile top plate; the first connecting plate and the second connecting plate are convenient to connect, mount and use, the pressure bearing base further improves the overall pressure resistance, and the reinforcing ribs and the regular hexagonal pressure resistance bodies are combined, so that the overall compressive strength can be improved, and overall distortion and deformation can be prevented.
Description
technical field [0001] The invention belongs to the technical field of railway fittings, and in particular relates to an aluminum alloy profile, which is mainly suitable for high-speed rail tracks. Background technique [0002] With the continuous development of science and technology, high-speed rail has been widely used in various cities. At present, the bus bar of the overhead rigid suspension system of domestic urban rail transit is generally made of aluminum alloy profiles. The main function of the bus bar is to conduct current and clamp the contact wire. Therefore, there are certain requirements for the conductivity and mechanical properties of aluminum alloy. Reach tensile strength ≥ 215MPa, yield strength ≥ 160MPa, elongation ≥ 8%, at 20°C, volume resistivity < 0.0329Ω.m m2 / m (equivalent to volume conductivity IACS of 52.5%). Since the strength of general aluminum alloy is not as good as that of steel, continuous annealing treatment is required to improve its str...
