Abstract

The invention provides a scalable and visual large-stroke caliper which is provided with a main scale, a fixed clamp leg, a flexible clamp leg, a handheld scalable rod, a connecting rod, a hand cranking controller, horizontal angle and vertical angle fine adjusting knob mechanisms, a displayer, a wide-angle camera, a spring, a first steel strand connected with the hand cranking controller, a second steel strand connected with the horizontal angle fine adjusting knob mechanism, a third steel strand connected with the vertical angle fine adjusting knob mechanism, a transverse pin shaft for realizing relative longitudinal rotation of the connecting rod and the handheld scalable rod, a longitudinal pin shaft for realizing relative transverse rotation of the connecting rod and the main scale, afirst torsion spring which sleeves the transverse pin shaft and a second torsion spring which sleeves the longitudinal pin shaft. When the size of the high altitude structural component is measured,the caliper can extend to the surface of the measured component, the head of the caliper can moderately rotate to measure the component which cannot be seen, and the technician only requires to operate on the ground so that the caliper is safe and reliable, accurate in measurement result, easy to operate and low in measurement cost and solves the problem of danger caused by high altitude operation.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a scalable and visualized large-stroke caliper, which can be used in the field of civil engineering measurement, especially for ancient building engineering surveying and mapping. Background technique [0002] In the process of engineering measurement, some components are higher than the ground, such as roof truss components, especially some ancient buildings have many types of components, and the measurement is very complicated. Generally, ladders or mobile scaffolds are used for measurement, which is very dangerous due to high-altitude operations. Especially for components with circular or other irregular cross-sections, such as columns, purlins, beams and other components, the traditional measurement method has large data errors. Other optical measurement or oblique photography methods are accurate but the operation is cumbersome and the cost is high. . [0003] The inventor retriev...
