Vibration reduction joint plate for straddle type monorail turnout

Abstract

The utility model discloses a vibration reduction joint plate for a straddle type monorail turnout, and aims to effectively improve the stability and comfort when a train passes through the turnout and ensure the driving comfort. A first straddle plate and a second straddle plate are arranged in parallel and span a beam seam; vibration reduction base plates and bases are arranged below the left side end and the right side end of the first straddle plate respectively, a concave long circular hole and a concave bolt hole are formed in the plate faces of the left side end and the right side end of the first straddle plate respectively, and a concave bolt hole and a concave long circular hole are formed in the plate faces of the left side end and the right side end of the second straddle platerespectively. The section of a base is in an L shape, the base is provided with a bearing plate and a boss with the longitudinal inner side protruding upwards, and the top face of the boss is flush with the plate face of the first straddle plate and the plate face of the second straddle plate. Each base is fixedly connected with a turnout beam on the same side, and the first straddle plate and the second straddle plate are fixedly installed on the corresponding bases through bolt assemblies penetrating through the inwards-concave oblong holes, the inwards-concave bolt holes and the installation holes in the vibration reduction base plate.

Description

technical field [0001] The invention relates to a straddle-type rail transit, in particular to a vibration-damping seam plate for a straddle-type single track switch. Background technique [0002] As an important type of urban rail transit, straddle-type monorail transit can be applied to urban passenger transportation with small, medium, and short, medium or long distances. In the turnout used for straddle monorail vehicles, the turnout is spliced ​​by multi-section turnout beams. Seam panels are installed. [0003] At present, finger joint plates are mainly used in the internodes of straddle single track turnout beams. Since the fingers of the finger joint plates are located at the beam joints, the fingers of the finger joint plates are prone to deformation under the action of loading and unloading of trains. , may cause fatigue damage. And when the adjacent turnout girder shrinks, the fingers of the finger joint plates are separated from each other, which is unfavorabl...

AI Technical Summary

Problems solved by technology

[0003] At present, the internodes of straddle-type single-track turnout beams mainly use finger joint plates. Since the fingers of the finger joint plates are located at the beam joints, the fingers of the finger joint plates are prone to deformation under the action of train loading and unloading. , may lead to fatigue damage

And when the adjacent turnout girder shrinks, the fingers of the finger joint plates will be separated from each other, which is not conducive to smooth driving
