Abstract

The invention provides a distance measuring device for amplifying pier sinking displacement, which comprises a scale, a laser emitting assembly and a reflection assembly, wherein the scale is vertically arranged on the side surface of a pier; the laser emitting assembly comprises a laser emitter and a fixing piece. The laser emitter is arranged under the scale and obliquely fixed to the side faceof the pier through the fixing piece. The reflection assembly comprises a horizontal adjusting mechanism, telescopic mechanisms and reflecting mirrors. The number of the telescopic mechanisms is an odd number, and when the number of the telescopic mechanisms is larger than or equal to three, the multiple telescopic mechanisms are vertically arranged on the horizontal adjusting mechanism at intervals. Each telescopic mechanism comprises two telescopic single pieces which are symmetrically arranged; the reflecting mirror is vertically installed at the top end of each telescopic mechanism, the height of the corresponding reflecting mirror is adjusted through the action of a telescopic single piece, the reflecting mirrors are used for reflecting laser emitted by the laser emitters to the scale, amplification of pier sinking displacement is achieved, measurement errors are reduced, and the measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of bridge pier displacement ranging, in particular to a distance measuring device for amplifying the sinking displacement of bridge piers. Background technique [0002] Piers are the intermediate support structures of multi-span bridges, used to transfer dead loads and vehicle live loads to the foundations. In order to ensure the safety of the bridge pier supporting the bridge body, it is necessary to measure the sinking displacement of the bridge pier regularly to check whether the sinking displacement of the bridge pier occurs. However, most of the existing measurement equipment uses laser light to directly irradiate the bridge pier for measurement. Since the subsidence displacement of the pier is small, the error of the measured subsidence displacement of the pier is relatively large. [0003] To sum up, there is an urgent need for a ranging device for amplifying the sinking displacement of bridge piers ...
