Wheel type rotating cantilever underwater pier detecting device and working method thereof

Abstract

The invention relates to a wheel type rotating cantilever underwater pier detecting device. The device comprises a wheel type guiding rail frame which sleeves the outside of a pier. A bracket which circumferentially moves along the wheel type guiding rail frame is arranged on the wheel type guiding rail frame. A lifting assembly is arranged on the bracket. The lifting assembly comprises a liftingrod. A detecting assembly is arranged on the lower end of the lifting rod. The invention further relates to a working method of the wheel type rotating cantilever underwater pier detecting device. Thewheel type rotating cantilever underwater pier detecting device and the working method thereof not only have the advantage of simple and reasonable structural design, but also can perform circumferential and all-round detection and detection of different depths on the pier, are efficient and convenient, and have a broad application prospect.

Description

technical field [0001] The invention relates to a wheeled rotating cantilever underwater pier detection device and a working method thereof. Background technique [0002] The underwater structure of the bridge is an important part of ensuring the normal and safe operation of the bridge structure. However, its service conditions and environment are more severe than those of the above-water part, such as high static stress and fatigue stress underwater, river erosion , scrubbing, wear, cavitation, freeze-thaw and erosion (chemical corrosion and electrochemical corrosion) in severe cold areas, ship collision, ice floes and earthquake attacks, environmental loads (such as bio-fouling) and working loads transmitted by bridge superstructures, etc. , all easily lead to various damage defects of the underwater structure of the bridge, and are not easy to be found. These damages and defects lead to the reduction of the bearing capacity and durability of the bridge, seriously endange...

[0002] The underwater structure of the bridge is an important part of ensuring the normal and safe operation of the bridge structure. However, its service conditions and environment are more severe than those of the above-water part, such as high static stress and fatigue stress underwater, river erosion , scrubbing, wear, cavitation, freeze-thaw and erosion (chemical corrosion and electrochemical corrosion) in severe cold areas, ship collision, ice floes and earthquake attacks, environmental loads (such as bio-fouling) and working loads transmitted by bridge superstructures, etc. , all easily lead to various damage defects in the underwater structure of the bridge, and are not easy to be found

These damages and defects lead to a reduction in the bearing capacity and durability of the bridge, seriously endangering the driving safety and the life of the bridge

[0003] There are many cases of damage to the underwater structure of domestic bridges, but because the structure itself is exposed below the water surface, regular bridge inspections cannot be involved, and the problems are not easy to be exposed; and when designing bridges, the substructure design has a large safety factor, which is often regarded as As a relatively safe part, its safety has not received due attention
