Abstract

The invention relates to the technical field of distance measurement, in particular to a point-line mileage measurement device, comprising: a driving wheel rolling on the surface to be measured, a decimal scale gear transmission group, an integer scale gear transmission group, a gear transmission group arranged on the decimal scale The decimal dial at the end of the group and the integer dial arranged at the end of the integer scale gear transmission shaft; the beginning end of the decimal scale gear transmission group and the beginning end of the integer scale gear transmission group are both coaxially arranged with the driving wheel, and the decimal dial has a There are n scale lines arranged in an array around its circumference, the radius of the driving wheel is r, the transmission ratio of the decimal scale gear transmission group is a, the transmission ratio of the integer scale gear group is b, and the integer scale has an array around its circumference. The t scale lines of the cloth can be calculated according to the pointer index on the integer dial and the pointer index on the decimal dial to calculate the length of the driving wheel. The invention is easy to operate, and one person can measure the length of longer builds.

Description

technical field [0001] The invention relates to the technical field of distance measurement, in particular to a measuring device for point-line measurement of a relatively long distance. Background technique [0002] At present, the common devices on the market to measure the straight-line distance between the two ends are usually: tape measure, steel ruler measurement, line-of-sight measurement, photoelectric measurement, etc.; the measurement accuracy is not high, and the reading data is easily affected by human factors. Cause measurement errors, photoelectric measurement needs to use optical and electronic technologies, and it is inconvenient to use. Especially for the high-precision measurement requirements of large-scale engineering structural parts, it is difficult for the above-mentioned measuring devices to meet the requirements. On the other hand, when measuring large-scale structural parts, two people are often required to be located at the two ends of the required...
