Abstract

The invention is suitable for the technical field of urban rail vehicles, and provides an apron board limiting device of a rail train and the rail train. The apron board limiting device of the rail train comprises a train body, an apron board and an apron board mounting piece; and one of the apron board and the apron board mounting piece is provided with an arc-shaped slide way part, the other one of the apron board and the apron board mounting piece is provided with a sliding piece, and the sliding piece is located in the arc-shaped slide way part and is in sliding fit with the arc-shaped slide way part to limit the apron board. According to the apron board limiting device of the rail train, the arc-shaped sliding way part is arranged on one of the apron board and the apron board mounting piece, the sliding piece is arranged on the other one of the apron board and the apron board mounting piece, and the sliding fit between the sliding piece and the arc-shaped sliding way part is used for replacing a safety lifting rope and limiting the limiting position of the apron board, so that the problem of abnormal sound caused by collision between the apron board limiting device and the apron board or the car roof is solved, and the risk that the apron board limiting device is tangled with foreign matter such as birds and plastic bags is reduced.

Description

technical field [0001] The invention belongs to the technical field of urban rail vehicles, and more particularly relates to a skirt plate limiting device of a rail train and a rail train. Background technique [0002] The contactless power supply urban rail vehicle is a 100% low-floor train with a design speed of 70Km / h. Large equipment such as traction equipment, non-contact power supply equipment and air-conditioning units of this kind of train are placed on the roof. In order to ensure aesthetics and reduce wind resistance, skirts on both sides of the train are set on the roof of this kind of train. plate. At the same time, in order to facilitate the maintenance of the roof equipment, the roof apron is generally designed to be reversible. When the train is running normally, the roof apron is in a fixed state. When the train enters the warehouse for maintenance, the roof apron can be opened to realize the roof. Normal inspection of equipment. [0003] See figure 1 and...
