A subway vehicle air conditioning unit installation platform is characterized by comprising flat top plates on the two sides, vertical plates at the two ends, unit installation bases fixedly connectedto the flat top plates, a sealing frame, supplementary plates at the four corners and a frame below the flat top plates, wherein the frame comprises an end cross beam, two longitudinal beam assemblies, a plurality of cap-shaped cross beams, two Z-shaped beams and a small camber beam connected with a roof lower edge beam; the two longitudinal beams are the same in composition structure; longitudinal beams and transverse beams are connected through arc welding; the two Z-shaped beams are symmetrically arranged, and are positioned between the small camber beam and the cap-shaped cross beam; thesmall camber beam is connected to the Z-shaped beams; the two ends of the cap-shaped cross beams are connected with the longitudinal beams and the Z-shaped beams respectively; and the end cross beamsare welded to the longitudinal beams on the two sides. Compared with a unit platform where a small-opening unit is installed, the weight of the subway vehicle air conditioning unit installation platform is reduced by 10%, and the best installation and sealing effect and the best strength and rigidity requirements are achieved through the small weight of the unit platform.
Description
technical field [0001] The invention belongs to the technical field of car body structures of urban rail transit vehicles, and in particular relates to a platform structure of a subway car unit. Background technique [0002] With the rapid development of rail transit, the market demand for rail vehicles has increased significantly, and at the same time, air-conditioning units with various installation forms and structures have appeared. According to the summary of previous projects, the sealing structure between the roof-mounted air-conditioning unit and the vehicle is divided into air outlet sealing and integral sealing. According to the form of air outlet and return air, it can be divided into bottom air outlet and bottom return air, end air inlet and side return air, and end air inlet and bottom return air. [0003] The Los Angeles subway project requires that the air intake at the end, the return air outlet and the maintenance of the air conditioner are all at the lower...
