Abstract

The invention discloses a semi-high door provided with an idler wheel guide rail device. The semi-high door comprises a sliding door body, a guide rail (1) installed on the sliding door body, slide blocks (2) connected with the slide rail (1) and a driving device (3) which is used for driving the guide rail (1) and the slide blocks (2) to move oppositely; each slide block (2) comprises a shell (21), idler wheels which are installed on the shell (21) and are connected with the guide rail (1), and scraper plates (23) which are installed at the two sides of the shell (31); the driving device (3)comprises a motor (31) fixedly installed on a platform, a driving wheel (32) installed on the motor (31), tension wheels (33) which are installed on the platform and are located at the two sides of the driving wheel (32) respectively, and a belt (34) of which the two ends are fixedly installed at the two sides of a platform screen door. The friction damage of the slide blocks (2) and the slide rail (1) can be effectively reduced, the semi-high door has a good self-cleaning effect, and the service life of the platform screen door is prolonged.

Description

technical field [0001] The invention relates to the field of rail transit screen doors, in particular to a half-height door with a roller guide rail device. Background technique [0002] With the increasing population of big cities, road traffic is increasingly unable to meet the rapidly increasing traffic usage of people. The development of urban rail transit plays an important role in alleviating urban traffic congestion. Since the first subway was built in London in 1863, the subway, as an important means of urban rail transit, has been widely used in developed countries such as Europe and the United States, as well as domestic Beijing, Shanghai, Guangzhou, Shenzhen and other developed areas. [0003] As an important part of urban rail transit equipment, the screen door is in the open and closed operating state for a long time, so the design of the driving mechanism and guide rail structure that controls its motion has an important impact on the service life of the screen...
