Problems solved by technology

This scheme is unable to adapt to trains of different specifications used on the same line because its "bolt tongue" protruding amount is a fixed value; Therefore, the mechanism is not only impacted by the forward moving force of the vehicle, but also because the direction of movement changes at a right angle, so its wear and failure rate is bound to be large; in addition, the use of this mechanism must modify the platform surface, which is not easy to open in the existing used in the line
Another patented solution is to provide a gap adjustment device consisting of a frame, two pedals connected in a hinged shape, and a sliding mechanism driven by a hydraulic cylinder on the side of the platform near the track. Applicable to national railways but not to subways

Embodiment Construction

[0011] The embodiment in the figure is a gap eliminating mechanism composed of five layers of anti-stepping boards. The width of the mechanism is 50 mm when the anti-tread plate is fully retracted and 184 mm when fully extended. Assuming that the compartment door opening is 1300 millimeters, add 200 millimeters of parking accuracy error at both ends, and divide it into two because the mechanism is too narrow and too long, and the length of the mechanism is 850 millimeters. The height of the mechanism is 90 mm.

[0012] The power of the mechanism comes from a 550 geared motor (11) using a safe voltage. The 550 deceleration motor (11) is fixedly connected to the right-handed screw (8) through the frictional safety coupling (12) through the transmission flexible shaft C (13), and then through the transmission flexible shaft B (6) to the left-handed screw (4) It is fixedly connected, and power can also be transmitted to the next gap elimination mechanism through the transmission...

Abstract

The invention relates to a double-layer or multi-layer scalable foot-miss prevention plate mechanism for removing clearance between a rail transit carriage and a platform. The foot-miss prevention plates are overlaid and can move mutually. When a train arrives and stops stably, the foot-miss prevention plates are pushed forward until touching an outer casing of the carriage. When train doors are closed, the foot-miss prevention plates are withdrawn backward totally. The invention has the advantages of simple structure, low cost, easy maintenance and long service life and can totally put an end to passenger hurt accidents caused by the clearance between the carriages and the platform.

Description

technical field [0001] The invention relates to a mechanism for eliminating the gap between a rail transit carriage and a platform with a double-layer or multi-layer telescopic anti-stepping board, which belongs to the invention of an auxiliary facility of a rail transit station. Background technique [0002] In rail transit, the distance from the edge of the station platform to the center line of the track must meet the requirements of vehicles approaching the limit, and the station platform in the curved section must also widen the limit, plus the construction error in the civil engineering, so people in actual operation It can always be found that there is a large gap between the carriage and the platform after the vehicle has stopped; It is about 20 meters, so people, especially those located at both ends of the length of the carriage (when the carriage door faces the outside of the arc) or in the middle of the length of the carriage (when the carriage door faces the ins...
