Rectangular track beam of high-speed rail and processing technology thereof

Abstract

The invention discloses a rectangular track beam of a high-speed rail and a processing technology thereof. The rectangular track beam of the high-speed rail and the processing technology solve the problem that a rectangular track beam, processed by the prior art, of a high-speed rail cannot meet the requirements on precision and size. The rectangular track beam of the high-speed rail comprises topplates, web plates and moving plates. The processing technology mainly comprises the following steps: firstly, processing grooves in the top plates, the web plates and the moving plates by a bevelingmachine; then welding the web plates, the top plates and the moving plates; correspondingly welding two moving plates with two web plates by penetration welding; corresponding welding the moving plates with corresponding reinforcing rib plates by CO2 protective welding; and finally corresponding welding the two web plates with two sides of the bottom surfaces of the top plates. The rectangular track beam of the high-speed rail and the technology are wonderful in conception, scientific and reasonable in design, and convenient in operation; the precision and the size requirements of the rectangular track beam of the high-speed rail can be effectively ensured; the processed rectangular track beam of the high-speed rail is high in precision, and the size meets the running requirements of a monorail suspended vehicle of the high-speed rail, and the monorail suspended vehicle of the high-speed rail can effectively safely stably run on the rectangular track beam of the high-speed rail.

Description

technical field [0001] The invention relates to an empty iron rectangular track beam and a processing technology thereof. Background technique [0002] The track is the main force-bearing component of the air rail monorail suspension vehicle when it is running. The locomotive is suspended by the wheels on the roof and walks on the track of the beam, so the accuracy of the track beam and the size of the track beam directly affect the effect of the air-rail operation. The process of making the track beam determines the accuracy and size of the track beam. The traditional processing technology cannot reach the precision and size required for the empty iron rectangular track beam. [0003] Therefore, an empty iron rectangular track beam and its processing technology are designed so that the processed empty iron rectangular track beam can meet its precision and size requirements.
