Abstract

The invention provides a pantograph mounting platform and a metro vehicle. The pantograph mounting platform comprises a frame, a covering, a holder and a reinforcing beam. The frame is fixedly connected with a vehicle body. The covering is fixed on the frame. The holder is welded on the surface of the covering, opposite to the frame. The reinforcing beam is fixed on the surface of the covering, facing to the frame. The reinforcing beam matches with the holder in position. As the holder is welded on the covering of the pantograph mounting platform, making an opening on the covering is not needed. Therefore, rainwater is prevented from flowing into the pantograph mounting platform along the opening. Airtightness of the pantograph mounting platform is improved, and use reliability of the pantograph mounting platform is guaranteed.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a pantograph installation platform and a subway vehicle. Background technique [0002] The pantograph is an important part of the subway, and the pantograph is installed on the subway through the pantograph installation platform. [0003] Figure 1a Schematic diagram of the structure of the installation platform for the existing pantograph, Figure 1b for Figure 1a Partial sectional view of A-A. see Figure 1a and Figure 1b , the pantograph installation platform includes a frame 20 and a skin fixed on the frame 20 (not shown in the figure). Four openings 22 for installing a fixing seat (not shown in the figure) are opened on the skin, and the pantograph is installed on the above-mentioned fixing seat. The edge of the frame 20 is fixed with a reinforced angle steel 24, which is an L-shaped structure, and the right angle of the reinforced angle steel 2 protrudes from the frame 20, so ...
