Sliding hanging basket for repairing and cleaning stay cable sleeve of cable-stayed bridge

Abstract

The invention provides a sliding hanging basket for repairing and cleaning a stay cable sleeve of a cable-stayed bridge, belongs to the technical field of sliding hanging baskets, and aims to solve the problems of high mechanical cost investment and low working efficiency due to the fact that a tower crane needs to be rotated in a large range or the crane needs to be erected back and forth when existing hoisting equipment is matched with the hanging basket for repairing and cleaning. A main tower is arranged in the middle of the upper end face of the main beam, and six stay cables are connected between the front end face and the rear end face of the main tower and the upper end face of the main beam in a bilateral symmetry mode. Each stay cable is sleeved with a sleeve. Through cooperationof the sliding mechanism and the cable pulling mechanism, a worker located in the hanging basket body can repair and clean the stay cable sleeve at a short distance, due to the fact that a tower crane and a supporting crane do not need to be adopted, the mechanical cost investment is low, the work efficiency is high, it can be guaranteed that all parts of the stay cable sleeve are inspected, andthe work efficiency is improved. Therefore, damage, aging and omission of polluted parts of the stay cable sleeve are not easily caused.

Description

Technical field[0001]The invention belongs to the technical field of a sliding gondola, and more specifically, relates to a sliding gondola used for repairing and cleaning cable-stayed bridge cable casings.Background technique[0002]Cable-stayed bridge, also known as cable-stayed bridge, is a kind of bridge in which the main girder is directly pulled on the bridge tower with many cables. It is a combination of pressure-bearing towers, tensioned cables and bending beams. Structural system. It can be regarded as a multi-span elastically supported continuous beam with cables instead of buttresses. It can reduce the bending moment in the beam, reduce the building height, reduce the structural weight, and save materials. The cable-stayed bridge is mainly composed of pylons, main beams, and stayed cables.[0003]For example, application number: CN201611175961.1 The present invention relates to a wind-resistant and vibration-damping gondola for high-altitude operations, which includes sliding...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a sliding basket for the repair and cleaning of the cable-stayed casing of the cable-stayed bridge, to solve the current repair and cleaning of the cable-stayed casing due to the fact that the tower crane (or crane) It is completed with the hanging basket, and it needs to be repaired and cleaned according to the repaired and cleaned parts observed on the beam surface, and then the hoisting equipment is used to repair and clean the hanging basket. If the cleaning position is scattered, it is necessary to rotate the tower crane in a large range or support the crane back and forth, which leads to high mechanical cost and low work efficiency, and it is impossible to ensure that all parts of the cable-stayed protective casing are inspected, which is likely to cause damage to the cable-stayed protective casing. The damaged, aging and polluted parts of the pipe are missed, which greatly reduces the practicability of the hanging platform, and the disassembly of the existing hanging platform is time-consuming and laborious, which reduces the convenience of using the hanging platform
