Problems solved by technology

[0026] For the Philips silo with a diameter of more than 3m, the measurement error of this method is very large. The measurement error of the circumference of the Philips silo we need must be less than 5mm, so as to reduce the circumference manufacturing error of the spiral cylinder as much as possible.
[0027] At the same time, this method is only suitable for measuring absolutely circular Philips silos. For Philips silos with poor roundness, this method cannot be used, and it is also impossible for real-time measurement
[0028] In summary, in related technologies, the measurement method for Lipp silo not only cannot achieve real-time and dynamic measurement, but also is manual measurement, with low efficiency and high error

Abstract

The invention provides a circumference measurement method and device of a spiral tube. The circumference measurement device comprises a detection device, a signal transmission device, a first target object, a second target object and a controller. The detection device can detect the spiral length of the spiral tube during rotation and is connected with the controller. The signal transmission device can transmit a signal. The first target object and the second target object are arranged on the wall of the spiral tube, can rotate along with the spiral tube, and respectively reflect the signal. The controller can obtain the spiral length and the tube circumference of the spiral tube rotating for any circle according to the spiral length of the spiral tube detected by the detection device when the first target object and the second target object respectively reflect the signal. By means of the technical scheme, circumference parameters such as the circumference, the diameter and the circumference error of the spiral tube can be measured accurately in a real-time and online mode, so that timely adjustment can be performed on a manufacture device of the spiral tube, installation errors can be eliminated, and manufacture accuracy of the spiral tube can be improved.

Description

technical field [0001] The invention relates to the measurement field of a spiral cylinder, in particular to a method for measuring the circumference of a spiral cylinder and a circumference measuring device thereof. Background technique [0002] A typical spiral silo is the Lipp silo. The English name of the Lipp silo is LIPP Silo, sometimes called LIPP silo, LIPP silo, Lipp silo, LIPP tank, Lipp tank and so on. [0003] In 1968, German Lipp invented the use of SM-type special equipment to build a spiral double-layer curling steel silo (referred to as Lipp silo). In 1969, the first Philips steel silo was built in Germany. In 1972 Philips sold the worldwide license to build such silos to the Swiss Silo Systems Company. The company in turn sold building permits to silo engineering companies in sixty countries. In 1984, my country purchased the license to build Lipp silos. In April 1985, the first Lipp steel silo in China was built. [0004] Philips SM-type special equipm...
