Parallel steel wire stay cable manned maintenance trolley

Abstract

The invention discloses a parallel steel wire stay cable manned maintenance trolley which comprises a manned maintenance vehicle and a lifting system connected with the manned maintenance vehicle, themanned maintenance vehicle comprises an outer protection unit and an inner platform unit; the outer protection unit and the inner platform unit can only be connected in a matched mode in the axial direction of a cable body in a relative sliding mode; the outer protection unit and the inner platform unit are each provided with a fixing unit capable of tightly holding the cable body; a climbing system used for driving the outer protection unit and the inner platform unit to relatively slide in the axial direction of the cable body is arranged between the outer protection unit and the inner platform unit, and a rotating body system used for driving the outer protection unit and the inner platform unit to rotate in the circumferential direction of the cable body is arranged between the outerprotection unit or the inner platform unit and the fixing unit. According to the parallel steel wire stay cable manned maintenance trolley, the parallel steel wire stay cable manned maintenance trolley can climb along the lifted direction through main traction, and can lift and rotate along the cable body through a self power system, so that the parallel steel wire stay cable manned maintenance trolley can pass through a narrow space between the adjacent cable bodies.

Description

technical field [0001] The invention belongs to the technical field of cable stays, and in particular relates to a trolley for manned maintenance of cable stays with parallel steel wires. Background technique [0002] Stayed cables are an important structural part of cable-stayed bridges and are also commonly used in other buildings or structures. Conventional maintenance and detection methods include: spider man, scaffolding or simple cable maintenance platform, as shown in CN2310087Y and CN204530513U. It is simple and fast to use the spider man to carry out inspection and repair work, but the operator has a high risk and low safety and reliability; using the erected scaffold to carry out the inspection and maintenance of cable stays requires a large amount of work and high cost. When used for cable-stayed bridges The normal traffic of the bridge will also be affected during cable inspection and maintenance; the simple cable maintenance equipment is generally installed at ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the existing problems, the invention relates to a manned overhaul vehicle with parallel steel cable stays, which has a compact structure. It can not only make it climb along the lift through the main traction, but also can lift and rotate along the cable body through its own power system. , so that through the narrow space between adjacent cable bodies, to solve the current technical problems of cable-stayed maintenance equipment such as large structure, low degree of automation, poor safety and reliability, high risk for operators, and limited use
