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 particularly discloses a mobile bridge deflection detector. The detector comprises a first track and a first detectionvehicle which are arranged on a pier, a second track and a second detection vehicle which are arranged on a footpath of a bridge deck, and a third track arranged on the lower end face of the bridge deck. The first track is in the height direction of a pier, the second track is in the width direction of a footpath, and the third track is in the width direction of a bridge floor. The first detection vehicle can climb upwards along the first track, and a datum plate is horizontally arranged on the first detection vehicle; the second detection vehicle can move along the second track; the second detection vehicle is provided with an extension frame bent downwards, the lower end of the extension frame is provided with a horizontal frame, the horizontal frame is provided with a third detection vehicle, the third detection vehicle can move along a third track, the bottom of the third detection vehicle is provided with a detection table, the bottom of the detection table is provided with a detector, and the detector can make contact with the upper end face 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...
