Bridge crack measuring device for municipal bridge engineering

Abstract

The invention discloses a bridge crack measuring device for municipal bridge engineering. The structure of the device comprises a detector, a bracket, a controller, a guide rail, a transmission box, achassis and driving wheels; the upper end of the detector is horizontally fixed to the lower end of the bracket; the bracket is fixed to the bottom of the controller through a bolt; the pulley of thedetector is in clearance fit with the inner wall of the guide rail; the outer wall of the detector vertically penetrates the center of the inner wall of the chassis; the bottom of the transmission box is horizontally welded to the upper end of the outer wall of the chassis; and four driving wheels are provided and are vertically mounted at the bottom of the chassis through bolts. According to thebridge crack measuring device for municipal bridge engineering of the invention, a bridge surface can be accurately measured through the detector in the device. The improved bridge crack measuring device for municipal bridge engineering can automatically scan the bridge surface in all directions. The speed and accuracy of the measurement of the device can be automatically adjusted, and therefore,detection efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a bridge crack measuring device used in municipal bridge engineering, belonging to the field of measuring devices. Background technique [0002] The main symptoms of bridge diseases are increased deflection, surface damage, cracks, concrete carbonization, erosion and corrosion of steel bars, local structural damage of the structure, and man-made damage. Most of the diseases can be manifested in cracks, such as cracks due to increased deflection, surface cracks due to surface damage, cracks caused by corrosion of steel bars caused by carbonization of concrete, etc. The crack meter is mainly used to detect, record and measure concrete The width of cracks such as bridges, tunnels or piers. [0003] However, due to the long distance of the bridge in the existing technology, the speed of manual measurement using instruments is slow and not accurate enough, which consumes a lot of time.
