[0002] Special equipment refers to boilers, pressure vessels (including gas cylinders, the same below), pressure pipelines, elevators, lifting machinery, passenger ropeways, large amusement facilities and special motor vehicles within the site (factory) that involve life safety and are relatively dangerous. Among them, boilers, pressure vessels (including gas cylinders) and pressure pipelines are pressure-bearing special equipment; elevators, lifting machinery, passenger ropeways and large amusement facilities are electromechanical special equipment.

[0003] At present, in the production process, the probe of the endoscope is often used to inspect the inside of the pressure pipeline. The probe positioning device positions and fixes the probe, and then loosely inserts it into the pipeline for inspection. However, most of the current probe positioning devices can only inspect straight pipes, and it is difficult to pass through the inner wall of the bent pipe smoothly, which increases the difficulty of inspecting the bent pipe.

[0004] To this end, we provide a portable special equipment inspection probe positioning device to solve the above problems. Utility Model Content
