Abstract

The invention provides a measurement apparatus and belongs to the technical field of gas meter auxiliary equipment. The measurement apparatus comprises an angle measuring assembly and a positioning sleeve, wherein the angle measuring assembly comprises a support, a protractor and a connecting rod assembly, the protractor is installed on the support, the input end of the connecting rod assembly is in rotational connection with the positioning sleeve, and the output end of the connecting rod assembly is in rotational connection with the protractor; a first included angle is formed between the input end of the connecting rod assembly and the axis of a pipe joint, a second included angle is formed between the output end of the connecting rod assembly and the datum line of the protractor, and the first included angle and the second included angle are corresponding angles; and the positioning sleeve is used for sleeving the pipe joint and is parallel with the axis of the pipe joint. The measurement apparatus provided by the invention, when being used for measuring the inclination angle of the pipe joint, has the advantages of simple and rapid measurement operation and high angle measurement precision. Besides, repeated positioning operation is unnecessary, and the measurement efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gas meter auxiliary equipment, in particular to a measuring device. Background technique [0002] When measuring the angle or bending moment of a pipe or column, there are no perfect measurement tools, resulting in low measurement accuracy and low measurement efficiency, especially when measuring gas meter pipe joints. The gas meter pipe joint is connected with the gas meter casing by riveting or welding. According to the relevant national standard requirements of the gas meter, the bending moment of the pipe joint needs to be tested to judge its connection reliability. However, the bending moment test will cause the root of the gas meter pipe joint to deform and tilt, so it is necessary to measure the angle of the pipe joint after the bending moment test. The main tools used for general angle measurement are protractors or angle rulers, but when using these tools to directly measure the inclination angl...
