Road and bridge collapse deformation measuring device

Abstract

The invention relates to a road and bridge collapse deformation measuring device, comprising laser light reflecting plates and laser range finders. The front-back direction is defined as the X direction, the left-right direction is defined as the Y direction, and the up-down direction is defined as the Z direction. The laser light reflecting plates comprise a first reflector plate that is disposedperpendicular to a plane in which the X direction and the Y direction are located and is disposed obliquely to a plane in which the X direction and the Z direction are located. The laser light reflecting plate further comprises a second reflector plate that is disposed perpendicular to a plane in which the X direction and the Z direction are located and is disposed obliquely to a plane in which the X direction and the Y direction are located. The laser range finders comprises a first laser range finder corresponding to the first reflector plate and a second laser range finder corresponding tothe second reflector plate. The first laser range finder and the second laser range finder comprise laser emitting ends and laser receiving ends used for receiving the laser light reflected by the corresponding reflector plate. According to the road and bridge collapse deformation measuring device, the problems that the deformation measuring device in the prior art has many components and does not have a three-dimensional direction deformation measurement are solved.

Description

technical field [0001] The invention relates to a collapse deformation measurement device for road and bridge collapse deformation measurement. Background technique [0002] In order to ensure the safety of roads and bridges, it is necessary to monitor and measure the positions of roads and bridges that are prone to collapse and deformation, so as to avoid corresponding safety accidents. [0003] Chinese patent CN207763660U discloses "A Device for Measuring Bridge Deformation Using Lasers". The device for measuring bridge deformation includes a laser rangefinder. A light-transmitting mirror inclined at 45 degrees is set between the transmitting end of the ranging sensor and the receiving end of the laser ranging sensor. Both the horizontal scale and the horizontal scale are set on the pier. The horizontal scale includes several photosensitive elements, the transmitter of the laser ranging sensor, the receiving end of the laser ranging sensor, and the horizontal scale are co...
