Abstract: Objective: The installation accuracy of the straddle monorail contact rails directly affects the safety and smoothness of the straddle monorail vehicle collector shoe passing through. Moreover, low installation accuracy can lead to arcing and increased carbon brush wear. Therefore, it is necessary to improve the installation quality of the straddle monorail contact rails, analyze the problems that occur during the installation process, and propose corresponding solution measures. Method: Based on the dynamic displacement of the collector shoe and the installation limits of the contact rails, as well as the technical requirements for steelaluminum composite conductive rails in CJ/T 4142012 Technical Requirements of AluminumSteel Conductor Rail for Urban Rail Transit and the product maintenance manual, multiple sets of onsite measurement data are obtained after the installation of straddle monorail contact rails for Wuhu Rail Transit Line 1 and Line 2. For the problems encountered during the installation of the contact rails, such as the interference between segmented insulators and turnouts and the excessive planar deviation between segmented insulators and contact rails, causes are analyzed and corresponding solutions are proposed. Result & Conclusion: The influence of segmented insulator clearance for switching turnouts of different radii is not fully considered during the design stage, thus the interference between segmented insulators and turnouts occurred. To address this issue, measures such as local adjustment of turnouts or adjustment of segmented insulator dimension in construction drawings can be adopted. Due to factors such as the manufacturing accuracy of steelaluminum composite rail and segmented insulators, the smoothness of track beam, the thermal expansion coefficient of different profiles, the ambient temperature and tightening torque, there may be excessive planar deviation between the surfaces of steelaluminum composite rail and segmental insulators after equipment installation. This problem can be solved by adjusting the tightening torque within the range required by the installation manual and performing local grinding in areas where adjustment is not possible.
