Welding torch module for film-type water-cooled wall surfacing

Abstract

The invention discloses a welding torch module for film-type water-cooled wall surfacing. The welding torch module includes a front-and-back movement mechanism, a horizontal angle adjustment mechanism, a laser tracking mechanism, a servo swing mechanism, a vertical angle adjustment mechanism and a welding torch; the front-and-back movement mechanism includes an L-shaped mounting bracket and a moving plate; the horizontal angle adjusting mechanism is arranged on the moving plate, the horizontal angle adjusting mechanism includes a rotating plate with tooth lines and a hand wheel, the rotating plate is rotatably connected to the moving plate through a rotating shaft, and a gear in the hand wheel is in transmission connection with the tooth lines at the edge of the rotating plate; the laser tracking mechanism is fixed on the rotating plate through an adapter plate I, the laser tracking mechanism includes a driving device and a laser tracker, and the driving device drives the laser trackerto move to get close to or be far away from a workpiece to be welded; and the servo swing mechanism is fixed on an adapter plate II, the welding torch is fixed on the servo swing mechanism through the vertical angle adjustment mechanism, and the servo swing mechanism drives the welding torch to swing with respect to the workpiece to be welded leftwards or rightwards in the horizontal direction.

Description

technical field [0001] The invention relates to a welding torch module used for surfacing welding of a membrane type water cooling wall. Background technique [0002] The water wall is the main heating part of the boiler equipment. It is composed of several rows of steel pipes and distributed around the boiler furnace. The inside of the water wall is flowing water or steam, and the outside receives the heat of the flame of the boiler furnace. It mainly absorbs the radiant heat of the high-temperature combustion products in the furnace, and the working medium moves up in it, and evaporates when heated. [0003] High-temperature corrosion and wear of water-cooled wall tubes have always been a common and serious problem. High-temperature corrosion and wear of water-cooled wall tubes are related to the temperature of the working environment, sulfur content, flue gas and ash particle erosion. Surface surfacing welding can be used to protect the surface of the water cooling wall...

AI Technical Summary

Problems solved by technology

Surface surfacing welding can be used to protect the surface of the water cooling wall, that is, a layer of heat-resistant and corrosion-resistant materials is surfacing on the surface of the water cooling wall. On the one hand, surfacing welding has high labor cost, on the other hand, the welding efficiency is low
