Embodiment

[0027] like Figure 1-9 As shown in the figure, the steel tube emptying detection equipment specially used for concrete-filled steel tube arch bridges. The detection equipment includes a mobile component 1 and a detection component 2. The mobile component 1 is fixed on the side of the bridge, and the detection component 2 is set on the bridge frame. The mobile component 1 and the detection component 2 There is a telescopic structure 3 between, the bridge frame is composed of two arch frames, a vertical support frame and a horizontal frame, wherein the middle of the arch frame is concave and protrudes on both sides. The railings and supporting piles are also used to fix the arch frame, and there are two groups of moving components 1, detection components 2 and telescopic structures 3, and two groups of moving components 1, detection components 2 and telescopic structures 3 are respectively located on both sides of the bridge , which enables the device to detect two arches at th...

Abstract

The invention relates to the technical field of bridges, and particularly discloses a steel tube void detection device special for a concrete filled steel tube arch bridge, the steel tube void detection device comprises a moving assembly and a detection assembly, and a telescopic structure is arranged between the moving assembly and the detection assembly. The detection assembly on the arch-shaped frame slides through the telescopic shaft in a sliding mode, a wheel in the detection assembly rotates to enable a hammer in the detection assembly to continuously knock a steel pipe, finally, whether the steel pipe is disengaged or not is judged through knocking sound, and a reciprocating structure is arranged in the detection assembly; one-way rotation of the hammer is changed into two-way reciprocating rotation through the reciprocating structure, so that the internal space is saved, the power consumed by the hammer is reduced, the energy-saving effect is achieved, the equipment can span a bridge cross frame through splicing and air cylinder modes, the detection assembly can detect the whole bridge at a time, and the detection efficiency is improved. And the situation that the equipment cannot run due to the transverse frame is avoided.

Description

technical field [0001] The invention relates to the technical field of bridges, and specifically discloses a steel tube void detection device specially used for a concrete-filled steel tube arch bridge. Background technique [0002] The construction of span bridges requires the use of high-strength, light-weight and easy-to-construct engineering materials, and it is hoped that the structure has good ductility and recovery performance. The use of CFST composite materials in arch bridges can greatly reduce the self-weight of the bridge, and can also greatly reduce the weight of the bridge. Improve the dynamic performance of the structure, but due to the material properties, construction, stress and other factors of concrete and steel pipes, the phenomenon of concrete voids in the pipes often occurs. Therefore, the bearing capacity of the steel pipe arch is reduced, resulting in insufficient strength of the arch rib, and the bridge will collapse if the time is too long. SUMMA...
