AI Technical Summary

Technical Problem

The existing cable-stayed cable installation guide auxiliary device has friction problems during the tensioning process, which leads to deviations in tension force measurement, affects the prestress distribution and stress uniformity of the cable, and exacerbates component wear, reducing the service life of the device.

Method used

The design employs a reducing pipe and a rotating wheel. The reducing pipe consists of a small diameter section, a reducing diameter section, and a large diameter section. The rotating wheel is set perpendicular to the large diameter section and is used for rolling connection with the anchor cup to reduce friction.

Benefits of technology

It significantly reduces friction, improves the accuracy of tension force measurement, ensures uniform distribution of prestress, extends the service life of the device, and reduces maintenance and replacement costs.

Abstract

The utility model relates to stay rope installation technical field discloses a kind of stay rope installation guiding auxiliary device, comprising: reducing pipe, it includes integrally formed small diameter section, reducing section and large diameter section, small diameter section is used to be inserted in embedded pipe, and large diameter section is located embedded pipe outside and is provided with multiple through holes;Multiple groups of rotating wheels are rotatably connected on large diameter section, rotating wheel is set through through hole, the axis of rotating wheel is vertically arranged with the axis of large diameter section, and rotating wheel is used to be connected with anchor cup rolling connection.The utility model is provided with multiple groups of rotating wheels outside the large diameter section of reducing pipe, so that anchor cup is connected with rotating wheel rolling connection in installation and tensioning process, instead of directly with guiding pad or embedded pipe inner wall sliding contact.Can significantly reduce the friction of stay rope in installation and tensioning process, so that actual tensioning force is closer to design tensioning force, to improve the prestress distribution accuracy and stress uniformity of stay rope, ensure the overall structural performance of cable-stayed bridge.
