A retractable bridge detection arm and bridge detection platform

Abstract

The invention relates to the technical field of bridge detection, and discloses a retractable bridge detection arm and a bridge detection platform. The retractable bridge detection arm includes a flipping boom, a slewing frame, a flipping frame and a measuring arm; It is connected to the carrying platform on the pre-inspection bridge, and the other end is rotatably connected to the slewing frame; the turning frame is hinged to it along the central axis perpendicular to the rotation of the slewing frame; the first end of the measuring arm is slidingly connected to the turning frame, and the second end of the measuring arm The end is provided with a docking guide structure arranged along its sliding direction; the present invention can connect two sets of retractable bridge detection arms to the lower side of the pre-detection bridge to form a stable bridge detection arm. And the "simply supported beam" structure that can be adaptively adjusted not only reduces the vibration of the single cantilever-arranged measuring arm, but also ensures the detection effect of the corresponding sensor on the measuring arm, and greatly improves the accuracy and detection accuracy of bridge detection. efficiency.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a retractable bridge detection arm and a bridge detection platform. Background technique [0002] As an important part of road and railway transportation, bridges play a particularly important role in national economic construction. With the rapid development of the economy, the number of bridge constructions is increasing day by day. However, most bridges have also entered the maintenance period accordingly, so the demand for bridge inspections is increasing year by year. In the scope of bridge inspection, in addition to bridge deck inspection and bridge pier inspection, according to the requirements of the national standard, it is also necessary to inspect the bottom of the beam, that is, the bottom of the bridge deck, and inspect its cracks, voids, water seepage and other diseases. [0003] At present, bridge inspection vehicles (referred to as bridge inspection vehi...

Problems solved by technology

[0005] One of the purposes of the embodiments of the present invention is to provide a retractable bridge detection arm, which is used to solve the problem that the single-configured measurement arm on the existing bridge inspection vehicle is likely to generate high-amplitude vibrations due to the vibration conduction of the bridge deck, which directly affects The problem with the detection effect of the sensor
