Abstract

A height tracking device for a mechanical underwater arc cutting trolley comprises a fixed platform and a central post, the upper end of the central post is connected with the fixed platform which is connected with a port of a wire feeder, the lower end of the central post is a cylinder, an annular groove is formed in the external circumference of the cylinder, and one end of the annular groove is sequentially sleeved with a snap spring, a three-hole retaining clip, an oil-free lining and a spring from bottom to top; the oil-free lining and a middle hole of the three-hole retaining clip are coaxial, and the oil-free lining is in fastening connection with the three-hole retaining clip through a protruding shoulder arranged at one end and can be moved up and down to be installed on the outer circle of the central post in a sleeving mode; round holes are formed in the two ends of the three-hole retaining clip, a hollow conducting rod is installed in the round hole in one end in a close-fitting and penetrating mode, a fixing rod is installed in the round hole in the other hole in a close-fitting and penetrating mode, and the lower end of the hollow conducting rod is in threaded connection with a hollow conducting nozzle. The height tracking device is applied to arc cutting of an underwater automatic or semi-automatic mechanical trolley, is especially suitable for cutting a three-dimensional space workpiece, and is simple in structure, safe, reliable, convenient to operate and low in manufacturing cost, movement response is sensitive, and tracking adjustment is fast, convenient and accurate.

Description

technical field [0001] The invention relates to a height tracking device, in particular to a height tracking device for underwater cutting and welding. The invention belongs to the technical field of underwater arc cutting and welding materials. Background technique [0002] At present, when underwater workpieces are cut automatically or semi-automatically by submersibles or underwater robots, due to the unknown shape of the workpiece, it is difficult to control the distance between the cutting torch and the workpiece in real time, resulting in unstable arc length during cutting Or broken arc, arc extinguishing phenomenon, resulting in the failure of underwater cutting or poor cutting quality. Contents of the invention [0003] The purpose of the present invention is to provide a height tracking device that can be installed on an automatic or semi-automatic cutting trolley for underwater cutting in order to overcome the above-mentioned problem of unstable cutting torch he...
