Hanging basket for detecting and maintaining anchor mooring heads of boom and stay cable of bridge

Abstract

The invention discloses a hanging basket for detecting and maintaining anchor mooring heads of a boom and a stay cable of a bridge. The hanging basket mainly comprises a detecting platform, a suspension structure (comprising suspension belts, a suspension frame and a suspension arm), a supporting structure (comprising a supporting frame, a counterweight platform seat and a counterweight arranged on the counterweight platform seat) and a walking structure (comprising walking wheels and a track), wherein the detecting platform, the suspension structure, the supporting structure and the walking structure are sequentially connected; the detecting platform, the suspension frame, the suspension arm and the supporting frame are all of cube structures; the suspension belts are high-strength steel wire ropes; the value of a tension force of the suspension belts can be regulated through a chain block. According to the hanging basket disclosed by the invention, an assembling mode is adopted, components are light and convenient, transportation is convenient, disassembling and assembling are convenient and quick, and a dedicated hoisting device is not needed during disassembling and assembling; the hanging basket is mainly applied to the fields of detecting and maintaining construction of an anchor mooring head of the stay cable of a cable-stayed bridge and an anchor mooring head of the boom of a boom arch bridge, and the like. When the traffic flow on the bridge is larger, the detecting and maintaining construction time is longer, or the adoption of a bridge detecting operation vehicle is difficult, the hanging basket disclosed by the invention has the advantages of quickness in disassembling and assembling, good controllability, high safety and low cost.

Description

technical field [0001] The invention relates to the detection and maintenance field of anchor heads of cable-stayed cables of cable-stayed bridges, lower anchor heads of suspension rods of mid-mounted and lower-mounted arch bridges, and specifically relates to a method for detecting and maintaining bridge suspension rods and lower anchor heads of cable-stayed cables. Hanging basket for the anchor head. Background technique [0002] Cable-stayed bridges, medium-supported and under-supported hanger arch bridges, because of their small main load-bearing components, large spanning capacity, less restrictions on the clearance under the bridge and the elevation of the bridge deck, beautiful appearance, mature technology, and moderate construction costs , Many large and medium-sized cities and highways in our country are built more. The stay cables of the cable-stayed bridge and the suspenders of the arch bridge are the support system of the roadway of this type of bridge. If ther...

Problems solved by technology

However, in many cases, the inspection vehicle cannot be used, for example: (1) the sidewalks of urban bridges are wide, and the extension length of the boom of most inspection vehicles is less than 3 meters, which cannot be used; , the inspection vehicle cannot extend the arm to work; (3) cable-stayed bridges and boom arch bridges on expressways are mostly equipped with maintenance passages or sidewalks, and anti-throwing nets are installed, and the inspection vehicle’s large arm cannot be crossed to perform arm extension work; (4) In addition , the inspection vehicle needs to occupy 1 to 1.5 lanes during the operation. For the inspection of bridges with narrow bridge deck and large traffic flow, it will have a greater impact on the traffic on the bridge; Usually it is only 1-2 meters, and bridge operation vehicles cannot drive in; ⑹The sidewalks on urban bridges are relatively wide, usually 2-5m, but there are usually lighting pipelines under the sidewalks, and the cover plates above them for pedestrians are relatively strong. Low, unable to meet the inspection vehicle driving on it (the total weight of the inspection vehicle is more than 20 tons, and the rear axle is more than 12 tons, which greatly exceeds the carrying capacity of the sidewalk board); Large, especially when the inspection or repair period is long
