Problems solved by technology

This method is more accurate in ellipticity measurement, but because the round pipe needs to be rotated, and the steel pipe is often heavy and difficult to rotate, it needs the cooperation of rotating machinery, and it can only be applied to the ellipticity measurement of straight steel pipes

Abstract

The invention relates to the field of steel structure construction, in particular to a large-diameter steel pipe inner diameter ovality measuring device. The device is characterized by comprising a circular tube inner diameter rod support part, a slide rail and measuring rod part with scales and a detachable drawing board (11), wherein the circular tube inner diameter rod support part comprises a rod support outer sleeve rod (1), a movable adjusting rod (2), a fastening knob (3) and a strip-shaped rod support jacking block (4); the slide rail and measuring rod part with scales comprises a movable adjusting slide block (5), a fastening knob (6), a slide rail (7) with scales, a movable measuring rod (8), a semicircular measuring rod end part jacking block (9), a pencil fixing clamp (10) and a detachable drawing board (11); the device simplifies the measurement process of the inner diameter ovality of the large-diameter steel pipe, the measurement data of the device is accurate, and the measurement error can be read in real time through the scales; and through the detachable drawing board, visual recording of measured data can be realized.

Description

technical field [0001] The invention relates to the field of steel structure construction, in particular to a device for measuring the ellipticity of the inner diameter of a large-diameter steel pipe. Background technique [0002] At present, the existing tools for measuring ovality in steel pipe factories mainly include calipers, rod gauges, and electronic caliper gauges. Calipers and rod gauges are hand-held measuring tools, which are widely used in steel pipe processing plants and pipe bending plants. These two measuring tools measure the outer diameter and inner diameter of round steel pipes respectively. The operation is simple but the measurement error is large, and the experience of the measuring personnel is relatively high. High, the measurement readings are relatively random, and it is impossible to form an intuitive record of the data; while the electronic caliper is a large-scale measuring equipment, generally only can measure straight steel pipes, the measuremen...
