Problems solved by technology

[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 surface, and the light inside the hollow pier is not clear enough, there is a large uncertainty in the manual detection method, and because each The entrances of the bridge piers are of different sizes, and the diameters of the inner spaces of the bridge piers are also different, so there are certain difficulties for manual inspection

Embodiment 1

[0032] as attached figure 1 As shown in the figure, it is a structural schematic diagram of a top view of a bridge pier inner wall defect detection device provided in this embodiment. The device includes a motion control assembly 4, four telescopic support rods 3 are arranged on the outside of the motion control assembly 4, and rollers 2 are arranged on the outer ends of the telescopic support rods 3, and the rollers 2 are always attached to the inner wall 1 of the pier, and maintain The frictional force enables the whole device to slide up and down stably on the inner wall of the pier. The motion control component 4 communicates with the control center and receives work instructions from the control center to perform tasks.

[0033] An electric cylinder is arranged inside the telescopic support rod 3, and when subjected to the force of the inner wall 1 of the bridge pier, the electric cylinder will generate a pressing force of the same size to ensure that the telescopic supp...

Embodiment 2

[0040] as attached image 3 As shown, it is a flow chart of a method for detecting defects on the inner wall of a bridge pier provided in this embodiment, and the method specifically includes:

[0041]Step 1: Put the detection device into the detection port, and the whole device will automatically move to the inside. Every time a section is moved, the imaging component will perform a 360-degree data collection. The motion control component of the detection equipment executes the task after receiving the command from the control center. as attached figure 2 As shown, it is a schematic diagram of the working principle of the pier inner wall defect detection equipment used in the bridge pier inner wall defect detection method provided in this embodiment. The equipment enters from the entrance of the pier, moves downward and acquires image data, and moves downward when the equipment moves During the process, the imaging component rotates 360 degrees following the telescopic rod...

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...
