Problems solved by technology

[0004] The existing semi-height safety door driving guide generally adopts linear ball slide rail, and its balls and slide rails are made of carbon steel, which is easy to rust in harsh environments and cause safety door failure
At the same time, its installation accuracy requirements are strict, maintenance costs are high, running resistance is relatively large, and maintenance is inconvenient, etc., which also bring uncertain factors to the running stability of the half-height safety door.

Abstract

The invention relates to the field of rail transit platform gates, and provides a rolling wheel sliding rail driving device of a rail transit platform gate. The rolling wheel sliding rail driving device of the rail transit platform gate comprises a power mechanism, rolling wheel sliding blocks, a U-shaped sliding rail and a toothed belt driving mechanism. The power mechanism comprises a sliding block support, a motor support and a driving motor, wherein the motor support is fixedly connected with the sliding block support, and the driving motor is installed on the motor support. Each rolling wheel sliding block comprises a sliding block body, concentric rolling wheels, an eccentric rolling wheel and dust-preventing scraping plates, wherein the concentric rolling wheels and the eccentric rolling wheel are installed on the sliding block body and matched with the U-shaped sliding rail, and the dust-preventing scraping plates are installed on the two sides of the sliding block body. The U-shaped sliding rail is installed on the sliding gate. The toothed belt driving mechanism is connected with the U-shaped sliding rail, and comprises a toothed belt, a toothed belt clamping end and a toothed belt adjusting end. According to the rolling wheel sliding rail driving device of the rail transit platform gate, big rolling wheels move instead of small rolling balls, and therefore the running resistance is reduced, and the running stability is improved. Meanwhile, the rolling wheel sliding rail driving device of the rail transit platform gate further has the advantages of being quiet, being free of noise, pollution and maintenance, and being easy to install and adjust. The service life of the platform gate is prolonged.

Description

technical field [0001] The invention relates to the field of rail transit platform doors, in particular to a roller slide rail driving device for a half-height safety door of a rail transit platform. Background technique [0002] With the continuous acceleration of China's urbanization process, the rapid advancement of urbanization, especially the expansion of large cities, has brought about the demand for urban transportation. Urban rail transit has the characteristics of safety, comfort, speed, environmental protection, and large transportation volume, so it has become an inevitable trend for the sustainable development of major cities. [0003] As an important part of urban rail transit equipment, platform doors bring a safe and comfortable experience to people's travel. Due to the characteristics of urban rail transit, half-height safety doors are generally installed on ground platforms or elevated platforms, in a semi-open open-air environment, and the weather environm...
