Novel suspension bridge main cable and suspension cable comprehensive construction tooling

Abstract

The invention provides a novel suspension bridge main cable and suspension cable comprehensive construction tooling, and relates to the field of bridge construction equipment. The tooling comprises a trolley frame walking along a main cable armrest steel wire rope, wherein the two sides of the trolley frame are connected with hanging baskets; a windlass for providing power for the trolley frame walking is arranged on the trolley frame; a press rod prying mechanism is respectively arranged at the front side of a walking wheel group arranged at the front part of the trolley frame and the back side of a walking wheel group arranged at the back part of the trolley frame; each press rod prying mechanism comprises two press rods arranged in a bilateral symmetry way; one end of each press rod is hinged onto the trolley frame; the hinging end of each press rod is also rotationally connected with a press wheel. The tooling is provided with the press rod prying mechanisms, so that the trolley frame can stride over affiliated object obstacles on a main cable through the press rod prying mechanisms; the construction difficulty is lowered; the overhauling efficiency is improved.

Description

technical field [0001] The invention relates to the field of bridge construction equipment, in particular to a novel composite construction tool for main cables and slings of a suspension bridge. Background technique [0002] Suspension bridge is one of the main forms of super-long-span bridges. Compared with other structural bridges, suspension bridges can use less materials to complete relatively large spans, and the bridge deck is relatively higher. Temporary piers need to be built, which can be built on the surface of turbulent water, so it has become one of the preferred structures for modern bridge construction. [0003] The main cable is the main load-bearing component of the suspension bridge, and is generally made of high tensile strength steel (steel wire, steel strand, steel cable, etc.). The anti-corrosion maintenance of components is very important. The height difference of the main cable from the main tower of the bridge to the bridge deck is generally more th...

Problems solved by technology

[0003] The main cable is the main load-bearing component of the suspension bridge, and is generally made of high tensile strength steel (steel wire, steel strand, steel cable, etc.). The anti-corrosion maintenance of components is very important. The height difference of the main cable from the main tower of the bridge to the bridge deck is generally more than 100 meters.

[0004] At present, a working vehicle that can travel along the main cable is usually used for auxiliary maintenance work, but the existing main cable working vehicle is limited by its structure, and it is difficult to safely avoid the cable clips, intake and exhaust hoods, temperature and humidity sensors and other accessories on the main cable. objects, which increases the difficulty of maintenance; in addition, it is difficult to correct the deviation of the center of gravity caused by the external force during the operation of the work vehicle, which brings inconvenience to the operation and affects the safety.
