Description

Technical Field

[0001] The utility model belongs to the technical field of cable-stayed bridge construction, and more specifically, particularly relates to an auxiliary positioning device for a cable-stayed bridge cable guide tube. Background Art

[0002] Nowadays, the construction of various bridges has provided a lot of convenience for people. Among them, the cable-stayed bridge has realized the construction of longer distance bridges, which has greatly shortened people's travel time. When building a cable-stayed bridge, it is necessary to use a cable guide tube to drive one end of the cable to be transported to the top of the cable tower for fixation, so as to stabilize the bridge deck. In order to more conveniently fix the cable guide tube above the cable tower, an auxiliary positioning device for the cable guide tube of a cable-stayed bridge is needed. The existing auxiliary positioning device for the cable guide tube of a cable-stayed bridge is generally assisted by a tower crane. The cable guide tube is moved to the top of the cable tower through a hook, and then pushed to the steel frame outside the cable tower by the staff for welding.

[0003] For example, the existing application number: CN202321857432.5 discloses an auxiliary positioning device for a cable-stayed bridge cable guide tube, including a pair of positioning support structures and a connecting structure. The positioning support structure includes concentrically arranged inner fixings, outer fixings and a plurality of adjustment components. The adjustment components include a fixing frame arranged between the inner fixings and the outer fixings and an adjustment component screwed on the fixing frame. The support end of the adjustment component extends outward from the outer fixings and presses against the inner wall of the cable guide tube. The utility model uses two positioning support structures with the same structure to assist in the positioning and installation of the cable guide tube. Since each positioning support structure has a plurality of length-adjustable adjustment components, welding is completely unnecessary during use. By adjusting the support length of each adjustment component, it can be made concentric with the cable guide tube, thereby improving the installation accuracy of the positioning support structure and the cable guide tube, simplifying the installation steps, further improving the accuracy of the cable guide tube positioning, and providing a strong guarantee for the subsequent cable threading.

[0004] Based on the above, when the existing cable-stayed bridge cable guide auxiliary positioning device is in use, the rope pulls the hook to easily shake in the air, thereby causing the cable guide to shake, making it inconvenient for workers to perform positioning and affecting welding efficiency.
