Example Embodiment

[0031] Example 1

[0032] Append figure 1 As shown, it is a schematic diagram of a top surface structure of a pair of bridge in this embodiment. The device includes a motion control assembly 4, and four telescopic support rods 3 are disposed outside, and the outer end portion of the telescopic support rod 3 is provided with a roller 2, and the roller 2 is always bonded to the inner wall of the bridge pier and remains corresponding. The friction is so that the entire device can slide up and down on the wall of the bridge pier. The motion control assembly 4 is connected to the control center communication, and the work instruction execution task is executed by the control center.

[0033] The inside of the telescopic support rod 3 is provided with a tube. When the force is protected by the inner wall 1 of the bridge, the tank generates the same size compact force to ensure that the scalable support rod 3 is always bonded to the inner wall of the bridge pier and the imaging assembly ...

Example Embodiment

[0039] Example 2

[0040] Append image 3 As shown, it is a process block diagram of a defect detection method of a pair of piers provided in this embodiment, and the method includes:

[0041]Step a: a detection from the detection device into the mouth, the entire interior of the device to automatically action, an action for each interval, imaging assembly 360 will be a collection of data. After tasks motion control component detecting device receives command and control center. Append figure 2 , The inner wall of one kind pier piers are provided in the inner wall defect detection method employed in the embodiment of the working principle of the defect detection apparatus schematic pier from the entrance into the device, down action and the acquired image data, mobile device downwardly process, the imaging assembly to follow the rod in a 360-degree rotation of the image acquisition.

[0042] During the downward action detecting apparatus, since every diameter of the inner horizonta...

Abstract

The invention discloses bridge pier inner wall defect detection equipment and method. The equipment comprises a motion control assembly, wherein a telescopic support rod and an imaging assembly are arranged outside the motion control assembly, and a roller is arranged at the end part of the telescopic support rod; and the imaging assembly can rotate by 360 degrees around the motion control assembly, and the imaging assembly and the motion control assembly are in communication connection with a control center. Through combination of a mechanical structure and electrical equipment, the equipment can be always attached to the inner wall of a bridge pier, corresponding friction force exists, and the imaging assembly and the inner wall of the bridge pier can be always kept at a preset distance while the equipment can stably slide up and down on the inner wall of the bridge pier; and therefore, the equipment can obtain clear image data required by inner wall defect detection more accurately.

Description

technical field [0001] The invention belongs to the technical field of bridge pier defect detection, and in particular relates to a bridge pier inner wall defect detection device and method. Background technique [0002] The pier is mainly composed of a top hat and a pier body. The abutment is mainly composed of a top hat and an abutment body. The function of the top hat is to transmit the large and concentrated force transmitted from the bridge span support to the pier body and platform body in a dispersed and even manner. [0003] Bridge piers are divided into two categories: gravity piers and light piers. There are also three types of piers: solid piers, hollow piers, and pile or column piers. Among them, the light piers are hollow piers, which look like gravity piers, but they are hollow and thin-walled piers. [0004] In the detection of internal crack defects of hollow pier, because the surface material of the inner wall of the pier is mostly smooth cement pouring s...
