Flexible monorail turnout with high switch crossing speed

Abstract

The invention discloses a flexible monorail turnout with a high switch crossing speed, and belongs to the technical field of monorail turnouts. A positive wire rail beam, a positive fixed end and a lateral fixed end are arranged in a monorail line, a flexible beam body is arranged between the positive wire rail beam and the fixed end to communicate the positive wire rail beam with the fixed end, afixing device and a damping support device are arranged on the flexible beam body to effectively realize accurate connection and stable support of the flexible beam body, a guided vehicle, a guide rail and a driving device are matched to guide the flexible beam body in bending and abutting joint, and further smooth crossover of a train at the monorail turnout is realized. According to the flexible monorail turnout, smoothness of the turnout beam is effectively improved, interference and impact of the monorail train during beam replacement in a turnout zone are decreased, crossover comfort andsafety of the monorail train are greatly improved, the crossover speed and the efficiency of the monorail train are effectively increased, the crossover cost of the monorail train is reduced, and application of monorail transportation is promoted.

Description

technical field [0001] The invention belongs to the technical field of single track turnouts, and in particular relates to a high-speed flexible single track turnout. Background technique [0002] With the continuous development of the economy, the urban population is becoming more and more dense. The traffic problems caused by road congestion not only affect the normal life of urban residents, but also cause certain pollution to the environment. The emergence of straddle-type monorail traffic has greatly alleviated the problem of traffic congestion. It not only has the advantages of climbing steep slopes, turning sharp turns, low noise, and comfortable rides, but also the construction cost is only about 1 / 3 of the subway, and the operating speed is similar to that of the subway. Quite, so it is better adapted to the traffic conditions of modern cities. After decades of development, straddle-type monorail traffic has become an important means of transportation for urban peop...

Problems solved by technology

[0004] At present, the types of turnouts designed, manufactured and applied in the field of straddle-mounted single track turnouts in rail transit mainly include pivot type turnouts, joint type turnouts, and beam-changing type turnouts. Among them, there is no smooth transition between pivot type turnouts and track beams. It is not suitable for use on the main line; the structure of the beam-changing turnout is more complicated, the operation control is more complicated, and the accuracy is difficult to achieve, and its application is subject to certain restrictions; Although the turnout beam forms a broken line in front of the turning point during the turning point, and the multi-segment broken line is used to fit the curve, which
