Light full-sealed underwater automatic welding wire feeder

Abstract

A light full-sealed underwater automatic welding wire feeder comprises a wire feeder box, a wire reel mechanism, a speed reduction transmission mechanism, a gear transmission mechanism, a wire pressing mechanism and a sealing motor with a sealed waterproof function, wherein the wire feeder box is provided with multiple interfaces, and the wire reel mechanism, the speed reduction transmission mechanism, the gear transmission mechanism, the wire pressing mechanism and the sealing motor are sealed and insulated in the wire feeder box. The interfaces on the wire feeder box include the gas way interface, the power cable interface and the welding gun interface. The inside-box gas pressure balanced with the outside-box water pressure is formed in the wire feeder box through protection gas injected into the wire feeder box through the gas way interface. The sealing motor, the speed reduction transmission mechanism and the gear transmission mechanism are sequentially connected. A pressure passageway is formed between the installed wire pressing mechanism and the installed gear transmission mechanism. A welding wire wound on the wire reel mechanism is pressed when passing through the pressure passageway and is conveyed to the welding gun interface of the wire feeder box. The light full-sealed underwater automatic welding wire feeder has the beneficial effects that the weight is small, the sealing performance is good, and the possibility that the device fails when working under water can be greatly reduced. The invention belongs to the technical field of underwater welding.

Description

Technical field [0001] The invention belongs to the technical field of underwater welding, and particularly relates to a lightweight and fully sealed underwater automatic welding wire feeder. Background technique [0002] With the rapid development of the national economy and marine technology, a large number of marine projects need to be constructed and maintained, and marine projects continue to advance to the deep sea. Therefore, there is an urgent need for underwater welding. As the key technology of marine engineering construction and transformation, underwater welding has been paid more and more attention. Scholars and scientific research institutions have taken underwater welding technology as a subject for research, and due to the complexity and uncertainty of the underwater environment, there is currently no complete The underwater robot welding system is used in underwater engineering welding, so the application demand for underwater welding is becoming more and more ur...

Problems solved by technology

However, these existing devices only seal the wire feeder box, and multiple sealing treatments are used in the process of sealing the wire feeder box. Multiple sealing treatments are equivalent to "serial connection", even if the reliability of a single sealing treatment is high, However, the reliability of multiple sealing treatments is often unsatisfactory, so there is a possibility of water seepage in the equipment, which will cause damage to the motor and malfunction of the equipment; moreover, once water seepage occurs in the equipment, the equipment will be damaged, and the repair is difficult and expensive.

Furthermore, the existing underwater wire feeding device is bulky and heavy, and the underwater operation is inconvenient.
