Description

Technical Field

[0001] The utility model relates to the technical field of distance measuring wheels for communication engineering, and more specifically, to a distance measuring wheel for communication engineering with a calibration function. Background Art

[0002] In the existing technology, the distance measuring wheel for communication engineering is an important measuring tool, which plays a vital role in projects such as cable laying and optical fiber installation. However, there is a significant problem in the use of the existing distance measuring wheel, that is, it is impossible to effectively calibrate multiple distance measuring wheels. This calibration difficulty directly affects the measurement accuracy of the distance measuring wheel, which in turn has an adverse impact on the quality and efficiency of the entire communication project.

[0003] First, due to the shortcomings of the existing distance measuring wheels used in communication projects in terms of calibration, when multiple distance measuring wheels are needed for joint measurement in the project, it is difficult to ensure the consistency of the measurement data between these distance measuring wheels. Each distance measuring wheel may have deviations in its measurement results due to manufacturing errors, wear and tear, or environmental factors. Without effective calibration, this deviation will accumulate as the number of distance measuring wheels increases, eventually resulting in a large error between the overall measurement result and the actual distance, which seriously affects the measurement accuracy of key parameters such as line length and position in communication projects.

[0004] Secondly, the difficulty in calibrating the existing measuring wheels may also reduce the construction efficiency of the communication project. At the construction site, due to the inability to quickly and accurately calibrate multiple measuring wheels, engineers have to spend extra time and energy to repeatedly measure and calibrate to minimize errors. This not only increases the manpower cost of the project, but may also cause rework during the construction process due to inaccurate measurements, further extending the project cycle and affecting the progress and economic benefits of the entire communication project.

[0016] (III) Beneficial effects

[0018] 1. Through the design of the ranging wheel, synchronous belt, sensor, detection disc, fixed sleeve, pressure rod, pressure roller, clamping mechanism and fixing mechanism, the synchronous fixing and calibration of multiple ranging wheels are realized. The synchronous belt is engaged on two ranging wheels. By pushing the push rod, the position of the pressure rod is changed, so that the pressure roller presses on the synchronous belt, thereby tensioning the synchronous belt and the ranging wheel, and completing the synchronous calibration process of the synchronous wheel.
