Abstract

The invention discloses a measuring device for pipe circumference, and belongs to the technical field of measuring equipment for outer circumference of a large-diameter casting pipe. The measuring device comprises a supporting wheel located below the pipe and used for supporting the rotation of the pipe, a measuring roller arranged in contact with the outer wall at one end of the pipe, a first encoder installed on the measuring roller and used for measuring the rotation angle of the measuring roller, a second encoder connected with the pipe and used for measuring the rotation angle of the pipe, and a controller electrically connected with the first encoder and the second encoder. The measuring device for pipe circumference can solve the technical problem in the prior art that the manual measurement for the large-diameter pipe is time-consuming, laborious and inefficient, and can achieve the technical effects of high accuracy, time and labor saving, and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of measuring equipment for the outer circumference of a large-diameter cast pipe, and more specifically relates to a measuring device for the circumference of a pipe body. Background technique [0002] In the production of cast pipe, it is necessary to measure the outer circumference of the socket to ensure that the size is suitable for installation. The current measurement method is to manually measure with a soft ruler. For pipes with larger diameters (such as more than DN1500), manual measurement is extremely inconvenient. Contents of the invention [0003] The purpose of the present invention is to provide a pipe circumference measurement device to solve the technical problems of time-consuming, laborious and inefficient manual measurement of large-diameter pipes in the prior art. The technical effect of saving time and labor and improving efficiency. [0004] In order to achieve the above object, th...
