A kind of double-row stay cable lightning protection facility installation trolley and installation method thereof

Abstract

The invention discloses a double-row stayed-cable lightning-protection facility mounting trolley and further discloses a mounting method of the double-row stayed-cable lightning-protection facility mounting trolley. The double-row stayed-cable lightning-protection facility mounting trolley is used for conducting travelling operation on double-row stayed cables and comprises a trolley frame, a first connecting frame, a second connecting frame and a driving device. The trolley frame comprises a bottom plate, the first connecting frame is assembled on one side of the trolley frame, and two firstrollers are arranged on the first connecting frame. The second connecting frame is assembled on the other side of the trolley frame, and two second rollers are arranged on the second connecting frame.The driving device is used for driving a trolley to move along the stayed cables, and meanwhile the distance between the first rollers and the bottom plate is larger than that between the second rollers and the bottom plate. The double-row stayed-cable lightning-protection facility mounting trolley and the mounting method thereof are suitable for mounting operation of small-distance large-span double-row stayed-cable lightning-protection facilities of different angles, the construction quality can be ensured, the construction speed is increased, and the safety risk is greatly reduced.

Description

technical field [0001] The invention relates to the construction field of cable-stayed bridges, in particular to a trolley for installing double-row cable-stayed lightning protection facilities and an installation method thereof. Background technique [0002] A cable-stayed bridge is a bridge in which the girder is pulled on the tower column by several cable-stayed cables. A cable-stayed bridge is mainly composed of a foundation, a cable tower, a main girder, and a cable-stayed cable. The load on the main beam is transmitted to the main tower through the cable-stayed cable, and then to the bridge foundation from the main tower. The cable-stayed bridge is the main force-transmitting and load-bearing component of the cable-stayed bridge. The cable-stayed cable is composed of three parts: anchorages at both ends, cable force-transmitting parts in the middle and protective materials, which are called cable assemblies. Its materials include steel wire rope, thick steel bar, high...

AI Technical Summary

Problems solved by technology

[0006] (1) Install lightning protection facilities on the long-span double-row stay cables. Due to the large span of the stay cables, using traditional tower cranes and automobile cranes to install lightning protection facilities cannot meet the requirements in terms of space. At the same time, use cranes and baskets at high altitude operation, there is a great potential safety hazard;

[0007] (2) Install lightning protection facilities on the double-row stay cables with small spacing. Since the distance between the double-row stay cables is too small, it is impossible to install the stay cable inspection and maintenance robot, and the installation of lightning protection facilities is difficult to achieve

[0008] To sum up, at present, the installation of cable-stayed lightning protection facilities under the condition of small-spacing and large-span double-row cables is relatively difficult, which affects the construction progress and construction quality, and there are relatively large safety risks.
