摘要

本文介绍的研究材料旨在揭示解决电动桥式起重机制造过程中几何参数变形问题的现代方法。这个问题与工作中的安全要求密切相关。为解决这一问题,建议使用改进的技术,对桥式起重机和电动龙门起重机结构的几何参数进行大地测量监测。本文介绍了一种用于控制几何参数的激光镜面系统,该系统可以满足相当严格的要求。实验数据表明,这种方法是最可靠、最精确的方法之一。作者开发并使用了 "激光束-镜子 "系统装置,该装置应满足明确的方法要求。结果表明,垂直面上镜子的正确安装偏差会导致测量误差增大。研究是在激光反射镜装置的帮助下进行的。作为研究成果,并利用作者开发的程序,提出了一种用于固定激光束的矩形刻度。利用作者获得的成果,可以在允许值范围内确定测量精度。此外,还分析了工业企业桥式起重机结构几何参数的现有允许偏差。作者指出了现代现有方法的不足之处,并提出了新的大地测量设备及其实施方法。本文研究了所开发方法的准确性,这些方法可以确保和提高桥式起重机安全运行的保障。

Modern approaches to studying the accuracy of determination of deformation values in geodesic monitoring of crane equipment
The purpose of the research, the materials of which are presented in this paper, is to reveal modern approaches to combat the deformation of geometric parameters in the construction of electric overhead cranes. This issue is quite relevant in terms of compliance with safety requirements at work. To solve this issue, it is proposed to use the improved technique of geodetic monitoring of geometric parameters of constructions of overhead and electric gantry cranes. The paper describes a laser-mirror system for controlling geometric parameters, which allows considering fairly strict requirements. This method, as demonstrated by experimental data, is one of the most reliable and accurate. The authors developed and used the installations of the “Laser beam – mirror” system, which shall meet clear methodological requirements. It is shown that the deviation from the correct installation of the mirror in the vertical plane leads to an increase in measurement errors. The research was carried out with the help of a laser mirror device. As a result of the research and using the procedure developed by the authors, a rectangular scale for fixing the laser beam was proposed. The implementation of the results obtained by the authors will allow establishing the accuracy of measurements within the limits of permissible values. In addition, the existing permissible deviations of the geometric parameters of the constructions of overhead cranes at industrial enterprises were analysed. The authors identified the shortcomings of modern existing methods and proposed new geodetic equipment and methods of their implementation. The paper examines the accuracy of the developed methods that can ensure and increase the guarantee of safe operation of overhead cranes.
