Under high-speed operation and severe climatic conditions, it is necessary to test the various performances of the contact network to ensure the normal operation of the train; during the construction process, especially for curved sections, it is necessary to use a level meter in conjunction with a tower ruler to measure and locate the installation angle of the section cable bracket, and then use a level meter in conjunction with a level ruler to measure whether the section cable bracket arm is intruding into the limit.

[0003] However, currently, the angle measurement and positioning are all performed by using an angle measuring ruler. During the measurement process, the measurement personnel need to hold the measuring ruler at both ends to measure, and the whole process is very cumbersome. Utility Model Content
