Description

Technical Field

[0001] This utility model relates to a boiler-related technical field, specifically a welding device for boiler water-cooled wall components. Background Technology

[0002] The boiler water-cooled wall component welding device is a specialized piece of equipment for welding boiler water-cooled wall components, which can significantly improve welding efficiency and quality.

[0003] Chinese patent discloses a welding device for boiler water-cooled wall components (authorization announcement number CN 220547807 U). This patented technology utilizes the coordinated use of a first electric slide rail, a slider, a movable rod, a second electric slide rail, and a movable block. By turning on the switch of the first electric slide rail, the movable rod slides back and forth. Simultaneously, turning on the switch of the second electric slide rail drives the movable block to slide back and forth on one side of the movable rod, facilitating the adjustment of the welding head to any position and providing more comprehensive welding for water-cooled wall components. However, this patented technology lacks a device for adsorbing, fixing, and moving on a vertical water-cooled wall. The sliding adjustment method of the movable rod may also cause inconvenience for personnel in confined or special spaces. A method of rotating an electric welding machine should be added.

[0004] Therefore, those skilled in the art have provided a welding apparatus for boiler water-cooled wall components to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a welding device for boiler water-cooled wall components to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A welding device for boiler water-cooled wall components includes a welding torch, a rotating device, and a magnetic chuck device. The rotating device includes a first gear, a second gear, a third gear, a fourth gear, a motor, a motor cage, a first shaft, and a second shaft. The magnetic chuck device includes a car body, a roof bushing, a first wheel, a second wheel, an electromagnet, a first worm gear, a first worm, and a first micro motor. The welding torch is installed in the rotating device, and two identical magnetic chuck devices are symmetrically arranged on both sides of the rotating device.

[0008] As a further embodiment of this utility model: a second worm is installed at one end of the second micro motor, and a second worm wheel is installed above the second worm. The second worm wheel has the same structure as the first worm wheel, the first worm has the same structure as the second worm, the second micro motor has the same structure as the first micro motor, and the first wheel has the same structure as the second wheel.

[0009] As a further embodiment of this utility model: an electromagnet is installed at the center of the magnetic chuck device, a roof bushing is installed at the upper end of the electromagnet, two opening slots are arranged diagonally on the magnetic chuck device, and a first micro motor is installed in the opening slot near the first wheel. A first worm is installed at one end of the first micro motor, a first worm wheel is installed at the lower end of the first worm, and a first wheel is installed on the left side of the first worm wheel. A second micro motor is installed in the other opening slot on the magnetic chuck device near the second wheel.

[0010] As a further embodiment of this utility model: a motor and a motor cage are installed on the left end of the first gear, the motor is installed in the motor cage, the right end of the motor cage is rotatably connected to the first gear, the left end of the motor is fixedly connected to the motor cage, a first shaft is installed on the left end of the motor cage, the first shaft is fixedly connected to the motor cage, a second shaft is installed on the right end of the third gear, the left end of the first shaft is installed in the roof bushing on the left side of the rotating device, and the right end of the second shaft is installed in another roof bushing on the right side of the rotating device.

[0011] As a further embodiment of this utility model: a fourth gear is installed at the upper end of the cross bushing, a second gear is installed at the lower end of the cross bushing, and a welding torch is installed in the cross bushing. The welding torch is installed in the fourth gear, the cross bushing, and the second gear from top to bottom.

[0012] As a further embodiment of this utility model: the first gear meshes with the second gear, the second gear meshes with the third gear, the third gear meshes with the fourth gear, the second gear and the fourth gear are located on the right side of the first gear, a cross bushing is installed on the right side of the first gear, the first gear is rotatably connected to the cross bushing, the cross bushing is installed on the left side of the second shaft, and the cross bushing and the second shaft are rotatably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The magnetic trolley device used in this utility model can be manipulated by personnel to attach to and move along the vertical water-cooled wall of the boiler. Since the water-cooled wall is made of metal, mostly steel, magnetic attraction can be generated by energizing the electromagnet. The first and second micro motors control the first and second wheels, which are diagonally arranged, respectively, allowing the magnetic trolley device to move straight or turn. The structure inside the boiler is relatively cramped, with limited working space and poor air circulation for welders. The magnetic trolley device can save manpower and facilitate the adjustment of the welding torch position at any time.

[0015] 2. The rotating device used in this utility model allows the welding torch to rotate to a certain extent after being fixed to the water-cooled wall by the magnetic trolley device, thereby adjusting to a suitable welding angle. The motor rotates the first gear, causing the second and fourth gears to rotate around the first gear, which in turn causes the welding torch in the cross bushing to rotate around the first shaft. The third gear does not generate power but acts as an idler gear to increase the stability of the rotating device after installation. The rotational connection between the motor cage and the first gear prevents the first gear from rotating together with the first shaft. Attached Figure Description

[0027] A motor 205 and a motor cage 206 are installed on the left end of the first gear 201. The motor 205 is installed in the motor cage 206.

[0031] The magnetic trolley device 3 used in this utility model can be made to adhere to the water-cooled wall and move on the boiler water-cooled wall by personnel operating the magnetic trolley device 3 body or controller.

[0032] The rotating device 2 used in this utility model enables the welding torch 1 to rotate to a certain extent after being fixed to the water-cooled wall by the magnetic chuck device 3, thereby adjusting to a suitable welding angle. The motor 205 rotates the first gear 201, causing the second gear 202 and the fourth gear 204 to rotate around the first gear 201, thereby causing the welding torch 1 in the cross bushing 207 to rotate around the first shaft 208. The third gear 203 does not generate power but only acts as an idler gear to increase the stability of the rotating device 2 after installation. The rotational connection between the motor cage 206 and the first gear 201 can prevent the first gear 201 from rotating together with the first shaft 208.
