Description

Technical Field

[0001] The utility model belongs to the field of rail transit platform doors, and in particular relates to an integrated suspension device for rail transit platform doors. Background Art

[0002] Rail transit platform doors are generally divided into half-height platform doors and full-height platform doors. Half-height platform doors are usually fixed by lower support, while full-height platform doors are usually fixed by upper suspension. At present, the transmission mechanism of the full-height platform door system is generally a synchronous belt drive. The synchronous belt and the guide wheel are connected by a guide wheel connecting plate, and the guide wheel and the sliding door are connected by fasteners. During the transmission process, the synchronous belt transmits power to the guide wheel through the guide wheel connecting plate, and the guide wheel drives the sliding door to slide. However, with the previous synchronous belt transmission mechanism, the guide wheel connecting plate needs to be fixedly connected between the synchronous belt and the guide wheel by multiple bolts, and the guide wheel and the sliding door need to be connected by fasteners. The installation efficiency is low, and assembly errors are prone to occur during the process of multiple bolt connections, affecting the transmission effect. Summary of the invention

[0021] Further description is given below in conjunction with the accompanying drawings and specific implementation methods.

[0022] See also Figures 1 to 4 , an embodiment of an integrated suspension device for a rail transit platform door comprises a suspension bracket 1, a guide wheel bracket 2, a roller 3 and a guide wheel 4. The suspension bracket 1 and the guide wheel bracket 2 are both integrally formed of aluminum alloy, with a simple overall structure and high connection strength. A guide wheel bracket 2 is fixedly connected to the suspension bracket 1 through a connecting seat 6, one end of the connecting seat 6 is riveted to the suspension bracket 1 or the guide wheel bracket 2, and the other end is fixed to the guide wheel bracket 2 or the suspension bracket 1 by bolts. Two rollers 3 are located on both sides of the connecting seat 6, and are supported between the guide wheel bracket 2 and the suspension bracket 1 by roller shafts 5 respectively, for rolling cooperation with the upper end of the guide rail 16, and the roller shaft 5 is fixedly connected to the suspension bracket 1 or the guide wheel bracket 2, and can be fixed by riveting, bolting, or welding; a third strip-shaped mounting hole 7 is provided on the suspension bracket 1, and when the roller 3 and the guide rail 16 are installed and placed, the guide wheel 4 moves downward on the third mounting hole 7. After the installation is completed, the guide wheel 4 moves upward on the third mounting hole 7 to the bottom of the guide rail 16, and is fixed by bolts for rolling cooperation with the lower end of the guide rail 16.
