Embodiment

[0026] This embodiment is basically as figure 1 Shown:

[0027] The mobile bridge deflection detector includes a first rail 4 , a second rail 10 and a third rail 12 ; and also includes a first inspection vehicle 5 , a second inspection vehicle 8 and a third inspection vehicle 14 .

[0028] combine Figure 7 , There are two first rails 4, which are pre-embedded on both sides of the pier 3 respectively, and the first rails 4 are in the shape of a rack. There are two first testing cars 5, the first testing car 5 is provided with a first motor and two first rollers 31, the first motor is a double output shaft motor, and the first roller 31 is coaxially fixed on the first motor on the output. The outer wall of the first roller 31 is gear-shaped, and it can mesh with the first track 4. Both sides of the two first detection vehicles 5 are connected by the first connecting frame 6 and fixedly connected by bolts, facing the first bridge in the middle of the bridge deck 1. A referen...

Abstract

The invention relates to the technical field of bridge engineering detection, and specifically discloses a mobile bridge deflection detector, including a first track and a first detection vehicle arranged on a bridge pier, a second track and a second detection vehicle arranged on a walkway on a bridge deck, and The third track arranged on the lower end surface of the bridge deck; the first track is along the pier height direction, the second track is along the walkway width direction, and the third track is along the bridge deck width direction; the first detection vehicle can be along the first track Climbing upwards, a reference plate is horizontally provided on the first testing car; the second testing car can move along the second track, and the second testing car is provided with a downwardly bent extension frame, and the lower end of the extension frame is set There is a horizontal frame, on which a third testing vehicle is arranged, the third testing vehicle can move along the third track, a testing platform is arranged at the bottom of the third testing vehicle, and a detector is arranged at the bottom of the testing platform, and the testing instrument Can be in contact with the upper end surface of the reference plate. The invention aims to solve the problem of inaccurate detection results.

Description

technical field [0001] The invention relates to the technical field of bridge engineering detection, and specifically discloses a mobile bridge deflection detector. Background technique [0002] A bridge generally includes a bridge deck and piers, and fences and walkways are provided on both sides of the bridge deck. Bridge deflection detection is the main detection item in the static and dynamic load test. Its function is to detect the degree of deformation of the bridge under a certain static load. The bridge needs to be tested after it is completed or used for a certain number of years. Since the deformation of bridges under load is generally small, the detection accuracy is very high, so a high-precision dial indicator is required for detection. During the inspection, the dial indicator is in contact with the bottom of the bridge for measurement. Due to the high height of the bridge, in order to facilitate the inspection, the inspector usually uses a long pole to push t...
