Problems solved by technology
However, this intelligent robot can only move up and down along the cable, and cannot solve the problems of too many nodes, relatively short rods, and complex angles of the spatial rod system, so it cannot be directly applied to the integrity evaluation of the rods of the spatial rod system.

The invention provides an in-service rod piece magnetic flux test system and control method. The test system comprises a test robot and a control computer, wherein the test robot is composed of two moving test ends and a three-axis linkage joint; each moving test end is provided with a pincerlike arm, a five-axis linkage joint, a driving wheel, a photoelectric sensor, a lithium battery, a wireless antenna, a gyroscope and a processor, and each pincerlike arm is provided with a sliding bearing and a magnetic flux sensor. The in-service rod piece magnetic flux test system provided by the invention has the following advantages that the magnetic flux can be continuously measured along the axial direction of the rod piece, the robot is capable of changing self shape and climbing to the next rod piece according to a program setting path when meeting the rod piece node, and an in-service rod piece magnetic flux test can be continuously finished under high-altitude and complex environment without human intervention.
Description
technical field [0001] The invention belongs to the technical field of detection of steel structure parts, and in particular relates to a magnetic flux testing system and control method of in-service rod parts. Background technique [0002] Spatial bar structures have been widely used in large-scale construction facilities such as stadiums, convention centers, railway stations and bridges. However, as the main load-bearing members of long-span spatial structures, once the rods are damaged, the safety of these structures will be reduced, and catastrophic continuous collapse of the structure may occur. Since the space bar system structure was proposed less than 30 years ago, the large-scale construction of space structures in my country has only been in the past 10 years. Therefore, a large number of built space bar system structures will face the problems of detection and reinforcement in the future. [0003] How to evaluate the integrity of the member and obtain the interna...
