Large-diameter cylinder shell circumference measurement assistance device

Abstract

The present invention is an auxiliary device for measuring the circumference of a large-diameter cylinder joint, which includes a 7-shaped strut, a hanging pin is arranged at the end of the folded section of the strut, and a rotating pin is sleeved on the upper part of the straight section of the strut. Roller; the rotating roller is a cylindrical structure. The present invention can well solve the problem of measuring the circumference of the outer wall of a single-section tube in the link of the tower tube manufacturing group, and at the same time, it also meets the convenience of installation and disassembly, and can be operated quickly without being affected by the site and equipment, which improves the safety of operators factor, convenience, and measurement efficiency. The user only needs to hold the invention and a single person can complete the measurement of the circumference of the tower, without ladders or other tools, and the invention is convenient for measurement, and can stretch the tape around the established track and spread along the tower wall, and complete it at one time In this process, there is no need to repeatedly adjust the position of the tape measure.

Description

technical field [0001] The invention relates to an auxiliary device for measuring length, in particular to an auxiliary device for measuring the perimeter of a wind power tower. Background technique [0002] Wind power generation is an important form of wind energy utilization. Wind energy is a renewable, non-polluting, high-energy, and promising green energy. It is a strategic choice for countries all over the world to vigorously develop clean energy. In the manufacturing process of the wind power tower, after the single plate is rolled back into a circle, it is grouped into sections, and then the flange is assembled to form a complete section of the tower. During the pairing process of each section, it is necessary to measure the outer diameter perimeter of both ends to determine the amount of misalignment between each other and ensure that it does not exceed the requirements of the qualified specification. [0003] Usually the alignment process is carried out on the grou...

Problems solved by technology

[0003] Usually the alignment process is carried out on the ground. The only inconvenience of the traditional method for measuring the circumference of a single-section pipe with a diameter ranging from 3m to 5m is that when measuring the outer diameter circumference, the tape measure cannot be positioned at the top of the single-section pipe, and often the measurement personnel Tie the end of the tape measure to an iron block and throw it across the other side, while one person holds the tape measure and shakes it to the edge of the single-section pipe to measure. This method is not safe, and it is easy to damage the tape measure. The fixed edge size is not accurate.
