Embodiment Construction

[0027]The invention provides a cab side window for a rail transit locomotive, the side window includes 1-bottom beam, 2-card slot 1, 3-spring positioning block, 4-pretension spring, 5-side window fixing frame, 6 -Glass support beam, 7-glass fixed frame, 8-side window glass, 9-handle, 10-side window inner frame, 11-side window outer frame, 12-card slot two, 13-pull rod, 14-crank fixed plate, 15-crank, 16-connecting rod, 17-rail and 18-slider. The side window fixing frame and the bottom beam are all fixedly arranged on the floor or the side wall of the driver's cab; The width is adapted, and the height of the glass fixing frame is smaller than that of the side window fixing frame, so that the side window glass can slide up and down with the glass fixing frame and is set in the side window fixing frame; the glass support beam is horizontally arranged in the side window fixing frame and Used to support the glass fixing frame and the glass; the length direction of the slide rail i...

Abstract

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.

Description

technical field [0001] The invention relates to a driver's cab side window for rail transit locomotives, belonging to the technical field of locomotive windows. Background technique [0002] The side window of the cab is a main part of the locomotive cab. It is mainly used by the crew to observe the use status of the pantograph. It is used frequently and plays an important role in the safe operation of the locomotive. [0003] The side windows of the locomotive driver's cab currently in use use a crank-link mechanism, and the force on the entire window frame deviates from the center position, resulting in eccentric wear of the lower left corner and upper right corner of the side window. Such side windows of the driver's cab can basically meet the normal service life when the general locomotive depot is in operation. The severe eccentric wear in the upper right corner affects the normal use of the driver's cab side window. [0004] Patent 201020621003.4 relates to a side wi...
