Nondestructive testing robot for excavator

Abstract

The invention discloses a nondestructive testing robot for an excavator. The nondestructive testing robot for the excavator comprises a robot body and a testing system, and is characterized in that the robot body comprises six joint modules and two electromagnetic chuck modules, the joint modules include two I-shaped joint modules and four T-shaped joint modules, the four T-shaped joint modules are sequentially serially connected to form two end portions, the two I-shaped joint modules are movably connected with the two end portions respectively and are movably connected with the two electromagnetic chuck modules respectively, the testing system comprises an ultrasonic probe, a data acquisition unit and a remote controller, and the ultrasonic probe is connected with one of the electromagnetic chuck modules via a rotating shaft. The nondestructive testing robot for the excavator is excellent in movement performance, high in testing efficiency and applicable to nondestructive testing of ferromagnetic object surfaces, and has the advantages of safety, reliability and practicality.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an excavator non-destructive testing robot. Background technique [0002] At present, the amount of imported used excavators in my country accounts for more than 90% of the total excavator imports, and the quantity accounts for more than 35% of the total domestic sales. Such a huge number of old excavators will cause many problems such as environmental pollution and high energy consumption, the most serious of which is the huge hidden danger in production safety. Excavator inspection has become one of the important contents of import and export inspection and quarantine. One of the most important links in the inspection of excavators is the inspection of its structural parts. Due to the harsh working environment of the excavator, its structural parts are extremely prone to corrosion, and at the same time, it is prone to fatigue under the action of stress, which poses a great hid...

AI Technical Summary

Problems solved by technology

[0003] At present, the detection of old excavators is done manually, which has relatively large limitations and deficiencies, which are mainly reflected in: 1) The detection process is a kind of high-altitude operation, and there are huge potential safety hazards, such as falling, pinching, Hydraulic oil spray, etc.

2) The speed of manual detection is slow, and the consistency of detection cannot be guaranteed
