Existing bridge pier stud crack detection device

Abstract

The invention relates to the field of bridge detection devices. The invention particularly discloses an existing bridge pier stud crack detection device. The device comprises a first semi-arc support,a second semi-arc support, a first semi-arc guide rail and a second semi-arc guide rail, wherein the second semi-arc support is detachably connected with the first semi-arc support to form a circularring shape; the second semi-arc guide rail corresponds to the first semi-arc guide rail; the first semi-arc-shaped guide rail and the second semi-arc-shaped guide rail are fixedly connected with thefirst semi-arc-shaped support and the second semi-arc-shaped support respectively. Ultrasonic flaw detection devices and driving assemblies for driving the ultrasonic flaw detection devices to move along the rails are arranged on the first semi-arc-shaped guide rail and the second semi-arc-shaped guide rail, through driving of the vertical hydraulic cylinders, the vertical supporting connecting rods drive the first hinge connecting rods to move, and therefore the first idler wheels are pressed on the outer wall of the pier column. The device can automatically detect cracks on the outer side ofthe pier column, eliminates terrain limitation, and is higher in detection speed and large in detection area.

Description

technical field [0001] The invention relates to the technical field of bridge detection devices, and specifically discloses a crack detection device for existing bridge pier columns. Background technique [0002] The main symptoms of bridge diseases are increased deflection, surface damage, cracks, concrete carbonization, erosion and corrosion of steel bars, local structural damage of the structure, and man-made damage. Most of the diseases can be manifested in cracks, such as cracks due to increased deflection, surface cracks due to surface damage, cracks caused by corrosion of steel bars caused by carbonization of concrete, etc. The crack meter is mainly used to detect, record and measure concrete The width of cracks such as bridges, tunnels or piers. [0003] For large bridges, the scale of pier columns is often relatively large, and the detection speed of manual practical instruments is slow and the risk factor is high. Therefore, it is urgent to provide a detection dev...
