Description

Cross track measuring ruler for measuring staggered pipelines Technical Field The invention relates to the technical field of measurement, in particular to a cross track measuring ruler for measuring staggered pipelines. Background In many practical application fields such as pipeline installation, civil engineering and equipment maintenance, it is often necessary to accurately measure the relative position between two pipes or other cylindrical members arranged in a staggered manner in space. The core requirement of the measurement work is concentrated on two key dimensions, namely the vertical distance and the horizontal distance between two pipelines, for example, when installing pipeline brackets and connecting branch pipes or carrying out new hole opening pipe arrangement operation near the existing pipelines, the two groups of distance data are rapidly and accurately acquired, and the two groups of distance data are key preconditions for guaranteeing construction precision and improving construction efficiency, and directly influence the connection quality and the overall construction progress of subsequent engineering. However, the technical means adopted for the measurement requirements in the current industry have significant limitations, and the dual requirements of modern engineering on the measurement efficiency and the measurement precision are difficult to meet: The traditional ruler combination measurement method is a common mode, and is usually carried out by adopting a steel tape and a ruler in combination with a square, but the method is complex in operation flow and easy to produce accumulated errors. The measurement personnel need to confirm the projection datum plane with the help of ruler and square first, and then pass through many times to chi, reading, benchmark transfer and calculation just can obtain the result, and whole process often needs many people to cooperate, and each time to chi calibration, reading record and benchmark transfer operation all can introduce human error, leads to final measured data's accuracy to be difficult to obtain effective guarantee. Meanwhile, the method essentially decomposes the measurement problem of the space dimension into two plane problems for indirect measurement, and cannot directly and synchronously read out the vertical and horizontal distances, so that not only is the step redundant, but also the measurement cannot be smoothly implemented due to the shielding of a pipeline, the restriction of objective conditions such as narrow field construction space and the like, and the reference points of the two measurements are not uniform easily caused by a step-by-step measurement mode, so that the measurement error is further amplified. Another type of common tools are large fixed rectangular devices or profiling models, and the tools have the common problems of huge volume and heavy weight, are inconvenient to carry and carry, and are difficult to adapt to complex and changeable construction sites with various environments. More critical is that the measurement range is usually fixed, can not be flexibly adjusted according to actual measurement requirements, can only adapt to pipeline measurement scenes with specific spacing, has extremely poor universality and is difficult to meet measurement requirements of different projects and different pipeline layouts. In addition, the rough estimation method is adopted in part of construction scenes, the method is completely dependent on visual experience of constructors to judge, the measurement accuracy is extremely low, the basic requirement of modern engineering on the measurement accuracy cannot be met at all, serious problems of pipeline interference, incapability of accurate butt joint and the like in subsequent installation operation are extremely easy to occur, reworking and correction are further caused, and unnecessary waste of labor, material resources and time cost is caused. In summary, the existing technical means for measuring the space distance of the staggered pipeline generally have the core defects of complicated measuring flow, low measuring efficiency, large accumulated error, incapability of guaranteeing measuring precision, poor tool adaptability, serious limitation by site conditions, incapability of intuitively and synchronously acquiring space bidirectional distance data and the like. Therefore, a special measuring tool with high integration degree, visual and simple operation and accurate and efficient measurement is urgently needed in the field so as to effectively solve the problem of measuring the space distance of the staggered pipeline which puzzles the construction site for a long time. Disclosure of Invention The invention aims to provide a cross track measuring ruler for measuring staggered pipelines, which aims to solve the problem that the conventional measuring method can not quickly, intuitively and accurately measure the vertical and horizontal distances between
