Embodiment Construction

[0041] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0042] Such as figure 1As shown, the bridge bearing deformation and disease detection system includes a camera 1, a handheld computer 2, a telescopic support 3 and a foldable tripod 5 arranged on the side of the telescopic support 3. The handheld computer 2 is a touch-screen computer with an image analysis and processing system, which can accurately calculate the rotation angle and displacement of the bridge support. The handheld computer 2 is also equipped with a touch pen for operating the touch-screen.

[0043] The camera 1 comprises a camera working part, a signal transceiving device 1-4 arranged on the top of the camera 1, a base 1-3 at the bottom of the camera 1 and a spherical platform 1-2 arranged on the top of the base 1-3, the spherical platform 1 One end of -2 is fixed on the upper part of the base 1-3, and the other end is connected with the work...

Abstract

The invention relates to a bridge support deformation disease detection system. The bridge support deformation disease detection system comprises a camera, a handheld computer, a telescoping support and a tripod, and is characterized in that the camera comprises a camera working unit, a signal transmit-receive device, a pedestal and a spherical holder; the signal transmit-receive device is in wireless connection with the handheld computer to control the spherical holder to realize rotation of the camera; the working section of the camera working unit is circular, and comprises a fine definition spherical infrared lens which is arranged at the center of the working section and is provided with a CMOS image sensor, and a plurality of infrared LEDs at the edge of the working section; the camera is fixed on the telescoping support; the telescoping support comprises a support pedestal, a telescopic part, a driving mechanism and a control system; the control system is in wireless connection with the handheld computer; and the telescopic part comprises a plurality of telescopic aluminium magnesium compo pipes which are mutually telescoped. The bridge support deformation disease detection system can realize horizontal 360DEG and vertical +30DEG to -90DEG rotation of the camera, and can comprehensively detect bridge supports with different heights and in the narrow and small space.

Description

technical field [0001] The invention belongs to the field of highway engineering test and detection, and relates to a bridge support deformation and disease detection system, especially a detection process that can detect the displacement and corner defects of bridge supports in a narrow space and at different heights. The detection process is simple, easy to operate, A bridge bearing deformation and disease detection system with accurate detection results and high work efficiency. Background technique [0002] Bridge bearings are important structural components connecting the bridge superstructure and substructure. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the bridge superstructure to the bridge substructure, relieve the vibration of the bridge pier, and at the same time bear the horizontal displacement and rotation angle of the end of the bridge structure caused by the load. and deformation. [0003] However, due to ...
