Cab side window for rail transit locomotive
The invention provides a cab side window for a rail transit locomotive. The cab side window comprises a bottom cross beam, a side window fixing frame, a glass supporting beam, a glass fixing frame, side window glass, a crank-connecting rod-sliding block mechanism and sliding rails. The length direction of the sliding rails is vertically arranged, the sliding rails are located in the center of the side window fixing frame in the width direction, the bottom ends of the sliding rails are fixedly connected to the bottom cross beam, and the top ends of the sliding rails are directly or indirectly connected to the side wall of a locomotive cab fixedly. A sliding block matched with the sliding rails is connected with the glass supporting beam. One end of a crank-connecting rod assembly is fixedly connected to the side window fixing frame, and the other end of the crank-connecting rod assembly and the sliding block are connected to form the crank-connecting rod-sliding block mechanism so as to support the sliding block to vertically move up and down in the sliding rails along with the side window glass. An existing crank-connecting rod mechanism which is eccentrically stressed is replaced with the crank-connecting rod-sliding block mechanism which is centrally stressed, the improved side window is balanced in stress, abrasion to an aluminum alloy window frame is reduced in the opening and closing processes of the side window, and the normal service life of the side window is prolonged.
