Description

Technical Field

[0001] This utility model relates to the technical field of kiln welding and repair, and more specifically, to an adjustable-angle spray gun device for ceramic welding and repair in kilns. Background Technology

[0002] Ceramic welding repair technology is an advanced process for non-stop maintenance of high-temperature kilns (such as glass kilns and coke ovens) under hot conditions. The principle involves injecting a mixture of powdered refractory materials (such as silica or zirconium welding materials) and combustible metals (such as aluminum powder) into the damaged area of ​​the kiln through a welding torch. Under oxygen-assisted combustion, a vigorous oxidation reaction occurs (temperatures reach over 2000℃), generating a ceramic molten material that metallurgically bonds with the base material (such as silica bricks or AZS bricks), thereby repairing damage such as cavities and erosion on the kiln's inner wall. This technology can significantly extend the kiln's lifespan (by an average of 1-2 years) and reduce downtime losses, and is currently widely used in the glass and coking industries.

[0003] When repairing a kiln, workers need to hold a welding torch, aim one end at the repair location, and then spray the welding material onto the repair surface. This method of adjusting the angle of the spray torch is difficult to cover the complex structure of the kiln.

[0004] Based on this, the present invention provides an adjustable angle spray gun device for welding and repairing ceramics in kilns. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an adjustable-angle spray gun device for ceramic welding repair in kilns.

[0006] The adjustable-angle spray gun device for welding and repairing ceramics in kilns provided by this utility model adopts the following technical solution:

[0007] An adjustable-angle spray gun device for welding and repairing ceramics in kilns includes a movable base, an angle adjustment mechanism, and a spray gun. The angle adjustment mechanism is disposed on the top of the movable base, and the spray gun is disposed on the angle adjustment mechanism. The angle adjustment mechanism includes a pair of vertical bars, a driving component, and a rotating sleeve. The two vertical bars are disposed on the top of the movable base, the rotating sleeve is rotatably disposed between the two vertical bars, the spray gun is sleeved in the rotating sleeve, and the driving component is hinged between the movable base and the spray gun.

[0008] Preferably, the angle adjustment mechanism further includes a second driving component disposed on the outer surface of the rotating sleeve. A first gear is disposed on the output shaft of the second driving component, and a second gear is rotatably disposed on the side end of the rotating sleeve. The first gear and the second gear are meshed and connected, and the spray gun is inserted into the second gear.

[0009] Preferably, the top of the movable base is provided with a reciprocating moving mechanism for driving the spray gun to move back and forth.

[0010] Preferably, the reciprocating moving mechanism includes a pair of mounting plates disposed on the top of the moving base; a sliding rod is disposed between the two mounting plates, and a slider is slidably disposed between the two sliding rods; a lead screw is rotatably disposed between the two mounting plates, and a driving member for driving the lead screw to rotate is disposed on the side of the mounting plate; the slider is threadedly connected to the lead screw, and a mounting panel is disposed on the top of the slider; both vertical bars and the driving member are connected to the mounting panel.

[0011] Preferably, the drive component that drives the lead screw to rotate is a servo motor.

[0012] Preferably, the movable base includes a base plate and rollers disposed at the bottom of the base plate.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] The spray gun is moved up or down by a drive component, causing the rotating sleeve connected to the spray gun to rotate within two vertical bars, thus adjusting the spray gun's tilt angle (and height). A second drive component rotates gear one, which in turn rotates gear two, causing the spray gun to rotate, thus adjusting its horizontal angle. This structural design allows for continuous adjustment of the spray gun's pitch angle, enabling precise aiming at traditionally inaccessible areas such as the kiln top, side walls, and corners. The second drive component drives the gear set to rotate the spray gun, achieving 360° horizontal positioning.

[0023] Example 1

[0024] This utility model discloses an adjustable-angle spray gun device for welding and repairing ceramics in kilns. (Refer to...) Figures 1 to 4 An adjustable-angle spray gun device for welding and repairing ceramics in kilns includes a movable base 1, an angle adjustment mechanism 2, and a spray gun 3; the angle adjustment mechanism 2 is located on the top of the movable base 1, and the spray gun 3 is located on the angle adjustment mechanism 2.

[0025] like Figure 1 As shown, the movable base 1 includes a base plate and rollers disposed at the bottom of the base plate.

[0026] The angle adjustment mechanism 2 includes a pair of vertical bars 200, a drive component 201, and a rotating sleeve 202; the two vertical bars 200 are set on the top of the movable base 1, the rotating sleeve 202 is rotatably set between the two vertical bars 200, the spray gun 3 is sleeved in the rotating sleeve 202, and the drive component 201 is hinged between the movable base 1 and the spray gun 3. The drive component 201 is an electric actuator.

[0027] like Figure 1 and Figure 2 As shown, the angle adjustment mechanism 2 also includes a second drive component 203 disposed on the outer side of the rotating sleeve 202. The second drive component 203 is a motor. A first gear 204 is disposed on the output shaft of the second drive component 203. A second gear 205 is rotatably disposed on the side end of the rotating sleeve 202. The first gear 204 and the second gear 205 are meshed and connected. The spray gun 3 is inserted into the second gear 205.

[0028] Specifically, the spray gun 3 is pushed up or down by the drive component 201, thereby causing the rotating sleeve 202 connected to the spray gun 3 to rotate within the two vertical bars 200, thus completing the adjustment of the tilt angle of the spray gun 3 (and the adjustment of the position height of the spray gun 3). The gear 204 is driven to rotate by the drive component 203, which causes the gear 205 to rotate, thereby causing the spray gun 3 to rotate, thus completing the adjustment of the horizontal angle of the spray gun 3.

[0029] Through this structural design, the pitch angle of the spray gun 3 can be continuously adjusted, enabling the spray gun 3 to accurately point at parts that are traditionally difficult to reach, such as the top of the kiln, side walls, and corners. The drive component 203 drives the gear set to rotate the spray gun 3, achieving 360° horizontal positioning.

[0030] like Figure 3 As shown, the top of the movable base 1 is provided with a reciprocating moving mechanism 4, which is used to drive the spray gun 3 to move back and forth.

[0031] like Figure 3 As shown, the reciprocating moving mechanism 4 includes a pair of mounting plates 400 disposed on the top of the moving base 1; a slide bar is disposed between the two mounting plates 400, and a slider 401 is slidably disposed between the two slide bars; a lead screw 402 is rotatably disposed between the two mounting plates 400, and a driving component for driving the lead screw 402 to rotate is disposed on the side of the mounting plate 400; the slider 401 is threadedly connected to the lead screw 402, and a mounting panel 403 is disposed on the top of the slider 401, and the two vertical bars 200 and the driving component 201 are all connected to the mounting panel 403.

[0032] Specifically, the driving component that drives the lead screw 402 to rotate is a servo motor.

[0033] Specifically, the servo motor drives the lead screw 402 to rotate periodically in both directions, which causes the slider 401 to drive the mounting panel 403 to move back and forth, thereby completing the reciprocating movement of the spray gun 3 and performing linear welding at the weld point.
