Problems solved by technology

[0005] But this device still has several defects: 1 is that three telescopic guide rods are required to operate simultaneously, not only the structure is complicated, but also three people are needed to complete the large-diameter pipeline, which wastes manpower and material resources; 2 is the outer splint of its side rod fixing parts 51 It needs to be placed on the outside of the pipe wall to measure, which is okay for products that are still in the factory, but it cannot be measured for pipes that have been buried underground or installed in tunnels; 3 Especially for most cement pipes, the inner diameter is generally relatively large Rough, after a long time of use, the corners of the inner splint will be worn, and the wear is often uneven, resulting in unequal lengths of the inner splints on both sides of the telescopic rod, so that even after the telescopic side rod is vertical, the center of the guide slider will not It will not fall on the center of the pipe, and accurate measurement values ​​cannot be obtained

Embodiment 1

[0031] As shown in the figure, a measuring device for measuring the inner diameter of large-diameter electric power pipes is produced, which includes a chord 1, a chord wheel 2 and a chord height sliding rod 3, and the chord 1 and the chord height sliding rod 3 are straight and fixed in length. A long bar, the middle position of the chord 1 is provided with a vertical through hole 4, the chord height sliding bar 3 is passed through the vertical through hole 4, and the chord height sliding bar 3 can be placed in the vertical through hole 4 Smooth and free sliding, the chord wheel 2 is made by rollers, and the chord wheel 2 is provided with three, which are installed on the two ends of the chord 1 and the lower end of the chord height sliding bar 3 respectively; the upper end of the chord height sliding bar is set There is a rod cap, and the chord height sliding rod 4 is provided with a scale value. In this embodiment, the distance between the centers of the chord wheel 2 at the...

Embodiment 2

[0039] As shown in the figure, on the basis of Embodiment 1, the wheel bottom of the chord wheel 2 is made into a wide bottom to become a wide bottom chord wheel; in this embodiment, the wheels of the chord wheel 2 at both ends of the chord 1 are Bottom width 6 is made into 10cm; The chord wheel 2 wheel bottom width 6 on the described chord height sliding bar 3 in the middle is still made into the width of common roller; Can further ensure that three chord wheels are in large diameter when measuring like this On the same circular plane in the pipeline, once it deviates from the same plane, the wheel bottoms of the chord wheel 2 at both ends of the chord 1 will not be close to the inner wall of the pipeline at the same time, reminding the surveyors to adjust in time.

[0040] Further install bearing in the inside of described chord wheel 2, all install transverse shaft at the two ends of described chord bar 1 and the lower end of chord height slide bar 3, described bearing is in...

Abstract

A metering type electric power large-diameter pipeline inner diameter measuring device belongs to the technical field of electric power equipment measuring devices and comprises a chord member, a chord arc wheel and a chord height sliding rod, the chord member and the chord height sliding rod are straight long-strip rods, a vertical through hole is formed in the middle position of the chord member, the chord height sliding rod penetrates through the vertical through hole and can freely slide in the vertical through hole, and the three chord arc wheels are installed at the two ends of the chord member and the lower end of the chord height sliding rod respectively; scale values are arranged on the chord height sliding rod; the wheel bottom of the chord arc wheel is a wide bottom; spiral locking holes are dug in the chord members on the side edges of the vertical through holes, and spiral locking pins are arranged on the chord members; and a vertical positioning pipe is arranged on the upper side of the vertical through hole in the chord member. The beneficial effects are that the inner diameter of the large-diameter pipeline can be obtained through calculation only by measuring and reading the scale value on the chord height sliding rod, accurate measurement can be carried out by adopting the wide-bottom chord arc wheel, the measurement work can be completed by only one person, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of measuring devices for electric power equipment, in particular to a measuring device for measuring the inner diameter of large-diameter electric power pipelines. Background technique [0002] Metal supervision is the main measure to ensure the safety of electric power equipment. Metal supervision should implement the whole process of technical supervision and management of equipment selection, design, manufacture, installation, commissioning, trial production, operation, decommissioning, maintenance and technical transformation, and timely discover The problem is to take effective supervision measures, and the measurement of various pipelines is a basic work of metal supervision. In addition to the commonly used small-diameter wire pipes in power equipment, there are many large-diameter pipes with large diameters, especially large-diameter tunnel pipes, which are convenient for wiring construction of power...
