Flexible monorail turnout beam

Abstract

The invention discloses a flexible monorail turnout beam comprising a traveling plate (1), a beam frame (2) and a supporting plate (3). A rubber plate (4) is laid on the traveling plate (1); the traveling plate (1) is arranged on the beam frame (2); the supporting plate (3) is arranged at the bottom of the beam frame (2); the traveling plate (1) comprises a plurality of traveling plate units; eachtraveling plate unit comprises fingertips (101), finger seams (102) and steps (105); the fingertips (101) and the finger seams (102) are matched in shape; the fingertips (101) and the finger seams (102) of the front and rear traveling plate units are in lapping connection in a mutually-crossing mode and can rotate relatively. According to the flexible monorail turnout beam, the fingertips and thefinger seams of the traveling plate cross, so that while the smoothness and coherence of the upper traveling surface of the flexible turnout beam is guaranteed, impact on a passing train is reduced,slipping is prevented, vibration is absorbed, and safety and comfortableness are improved when the train passes a turnout in a high speed.

Description

technical field [0001] The invention belongs to the technical field of rail transit straddle type single track turnout, and more specifically relates to a flexible single track turnout beam. Background technique [0002] Straddle monorail is an important part of rail transit. Only one train straddles the rail, supported, stabilized and guided by a single track. For crowded cities, the straddle-type monorail 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, the operating speed is equivalent to that of the subway, and the transportation volume is close to Type B Subway trains are especially suitable for cities with medium traffic volume, complex terrain and geology, and hope to control urban rail construction costs and landscapes. The straddle monorail can well solve the problem of traffic congestion and can well adapt to the traffic conditions of modern c...

Problems solved by technology

At present, the types of turnouts designed, manufactured and applied in the field of straddle-mounted single track turnouts in rail transit mainly include articulated turnouts and joint-flexible turnouts, which occupy a large space; among them, articulated turnouts include broken-line and flexible, and broken-line When the joint type turnout is turned, the turnout beam forms a broken line shape in front of the turning point, and the multi-segment broken line is used to fit the curve. The disadvantage is that a sharp point is formed at the joint junction, the turnout line shape is not smooth, and a large impact will be generated when the train is running. , especially when driving at high speed; when the flexible joint type turnout turns, each joint can be bent into a curved line, and the transition between the joints is smooth. Coordination, curve smoothness is not easy to maintain

In summary, the existing turnout girders cannot simultaneously meet the requirements of multi-opening butt joints of single-line girders and smooth line shape of girders
