At present, plumb bobs are usually used for vertical correction or observed through theodolite or total station. Obvious; 2. Theodolite and total station can only observe a single vertical direction when they are in use, and cannot obtain accurate offset. The horizontal distance and elevation angle from the measurement point to the observed point need to be calculated, or can only be calculated. According to the experience of surveyors, and there is parallax limited by the maximum elevation angle of observation

Abstract

The invention belongs to the technical field of engineering detection, and particularly relates to a portable vertical calibrator, which comprises a light-emitting device and a reading light target matched with the light-emitting device, wherein the outer side of the light-emitting device is sleeved with a windproof cover, and a first bearing at the top of the light-emitting device is connected tothe top of the inner side of the windproof cover through a bearing assembly. According to the principle that the gravity center is vertically downward, the light-emitting device and the windproof cover are connected and provided with the vertically-crossed moving bearing to swing leftwards, rightwards, forwards and backwards, and finally vertical downward movement is achieved; a spotlight principle is applied, and condensation is realized by wirelessly and remotely controlling the movable convex mirror; the light-emitting device is powered by a storage battery and can be used as a balance weight of a real light-emitting device; the device has the characteristics of visual vertical deviation, simple structure, strong adaptability, rapidness, high efficiency and the like, and is large in vertical correction height, strong in flexibility, convenient to carry and strong in practicability.

Description

technical field [0001] The invention belongs to the technical field of engineering detection, in particular to a portable vertical calibrator. Background technique [0002] In the construction of engineering construction, vertical correction is required for vertical components or equipment during construction, installation or use to ensure the quality of the project. At present, plumb bobs are usually used for vertical correction or observed through theodolite or total station. Obvious; 2. Theodolite and total station can only observe a single vertical direction when they are in use, and cannot obtain accurate offset. The horizontal distance and elevation angle from the measurement point to the observed point need to be calculated, or can only be calculated. Based on the experience of surveyors, and there is parallax limited by the maximum elevation angle of observation. Contents of the invention [0003] The purpose of the present invention is to provide a new vertical ...
