Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for producing sootblower frames. Background Technology

[0002] In the welding production process of sootblower frames, the positioning angle iron is a key positioning tool. Its core function is to accurately position the sootblower frame components to be welded through physical support and spatial constraints, thereby assisting welding operators in achieving precise alignment and welding of the components. Therefore, the installation and disassembly efficiency of the positioning angle iron directly determines the smoothness of the overall welding process and production efficiency.

[0003] However, existing positioning angle irons are fixed to the welding platform with bolts. When the positioning angle iron is fixed to the welding platform with bolts, adjusting its position requires using tools such as wrenches to tighten or loosen the bolts one by one. In large-scale welding operations, positioning angle irons need to be frequently replaced to adapt to the welding requirements of different parts. The existing connection method requires disassembling the bolts one by one. This connection method is not convenient for quickly adjusting the position of the positioning angle iron, thus reducing welding efficiency. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 7This utility model provides an embodiment of a welding device for producing a sootblower frame, comprising a welding platform 1 and a welding assembly 2. The welding assembly 2 consists of a welding torch and a gas cylinder. Positioning angle irons 3 are uniformly arranged on the top surface of the welding platform 1. A connecting assembly 4 is provided between the positioning angle irons 3 and the welding platform 1. A filter assembly 5 is provided above the welding platform 1. The connecting assembly 4 includes positioning holes 41 uniformly opened on the top surface of the welding platform 1 and through holes 42 uniformly opened on the bottom surface of the welding platform 1. Ring blocks 43 and springs 44 are uniformly arranged inside the welding platform 1. A pressing block 45 is fixedly connected to the end of the spring 44 away from the welding platform 1. The surface of the ring blocks 43 is provided with... The system includes a connecting groove 46, connecting grooves 47 on the surface of the annular block 43, symmetrical through grooves 48 on the surface of the positioning angle iron 3, symmetrical connecting posts 49 inside the positioning angle iron 3, snap-fit ​​blocks 411 fixedly connected to the bottom surface of each connecting post 49, positioning holes 41 and through holes 42 communicating with each other, annular blocks 43 fixedly connected between the inner wall surfaces of positioning holes 41 and flush with the top surface of the welding platform 1, springs 44 fixedly connected between the bottom inner wall surface of positioning holes 41 and the bottom surface of pressing blocks 45, pressing blocks 45 slidably connected inside positioning holes 41, connecting grooves 46 communicating with positioning holes 41, and connecting grooves 47 communicating with connecting grooves 46. The through slots 48 are all on the same horizontal line as the corresponding through slots 46 and positioning holes 41. The connecting posts 49 are all rotatably connected inside the through slots 48. The snap-fit ​​blocks 411 are adapted to the connecting slots 47. The number of snap-fit ​​blocks 411 at the bottom of a single connecting post 49 is the same as the number of connecting slots 47 on the surface of a single annular block 43. The snap-fit ​​blocks 411 are all slidably connected inside the positioning holes 41 through the connecting slots 47. The bottom of the snap-fit ​​blocks 411 abuts against the top surface of the pressing block 45. Before welding, the sootblower frame components to be welded are positioned using the positioning angle iron 3. During operation, the connecting posts 49 of the positioning angle iron 3 are aligned with the positioning holes 41 of the welding platform 1. The locking block 411 is inserted into the corresponding connecting slot 47. During this process, the locking block 411 presses down on the pressing block 45, and the compression spring 44 moves downward, so that the locking block 411 enters the positioning hole 41. Then, the connecting column 49 is rotated, so that the locking block 411 inside the positioning hole 41 rotates. At this time, the locking block 411 is no longer on the same horizontal line as the connecting slot 47. The bottom of the locking block 411 abuts against the top surface of the pressing block 45. Because the pressing block 45 is squeezed by the locking block 411, the compression spring 44 moves downward. The reaction force of the spring 44 makes the top of the locking block 411 fit tightly with the bottom surface of the annular block 43, thereby completing the fixing of the positioning angle iron 3.

[0024] Please see Figure 1 - Figure 7The filter assembly 5 includes four columns 51 fixedly connected to the four corners of the top surface of the welding platform 1. A mounting plate 52 is fixedly connected to the top surface of the four columns 51. A mounting groove 53 is formed in the center of the surface of the mounting plate 52. A connecting pipe 54 is fixedly connected inside the mounting plate 52. An activated carbon adsorption filter element 55 is placed inside the connecting pipe 54. An annular insertion groove 56 is formed on the top surface of the connecting pipe 54. A protective filter cover 57 is provided above the connecting pipe 54. A mounting frame 58 is fixedly connected between the inner wall surfaces of the protective filter cover 57. A cooling fan 59 is installed inside the mounting frame 58 and is driven by a motor. An annular insert plate 511 is fixedly connected to the bottom surface of the protective filter cover 57. A collection cover 512 is fixedly connected to the bottom surface of the mounting plate 52. The connecting pipe 54 is fixedly connected to the inner wall surface of the mounting groove 53, and the annular insert plate 511 is slidably connected to the inside of the annular insert groove 56. The connecting pipe 54 and the inside of the collection cover 512 are interconnected. The collection cover 512 is set directly above the welding platform 1. During the welding process, the cooling fan 59 is started to generate negative pressure. The welding fumes generated above the welding platform 1 are sucked into the inside of the connecting pipe 54 through the collection cover 512. The collection cover 512 can completely cover the welding area to ensure efficient collection of fumes. After the fumes enter the connecting pipe 54, they are filtered by the activated carbon adsorption filter element 55. Particulate matter and harmful gases are adsorbed on the surface of the activated carbon adsorption filter element 55, and the filtered air is discharged through the top of the protective filter cover 57, thereby reducing the health hazards of welding fumes to operators.

[0025] Working principle: Before welding, the positioning angle iron 3 is used to accurately position the sootblower frame component on the welding platform 1 according to its size and shape. During operation, the connecting post 49 at the bottom of the positioning angle iron 3 is aligned with the pre-set positioning hole 41 on the surface of the welding platform 1. At the same time, the snap-fit ​​block 411 at the bottom of the connecting post 49 is aligned with the connecting groove 47 on the surface of the annular block 43 and inserted. During this process, the snap-fit ​​block 411 will gradually press down the extrusion block 45 in the positioning hole 41, causing the spring 44 to be compressed and move downward, thereby providing sufficient space for the snap-fit ​​block 411 to enter. When the snap-fit ​​block 411 is fully inserted... After entering the positioning hole 41, rotate the connecting column 49 to make the locking block 411 deviate from the original position of the connecting groove 47. At this time, because the bottom of the locking block 411 is supported by the pressing block 45, and the pressing block 45 is pressed tightly against the locking block 411 due to the reaction force of the spring 44, the top of the locking block 411 and the bottom surface of the annular block 43 form a tight fit, thereby realizing the stable fixation of the positioning angle iron 3 on the welding platform 1. After the soot blower frame component is fixed by the positioning angle iron 3, the welding gun in the welding assembly 2 is used to weld the parts that need to be welded. During the welding process, in order to reduce the welding output... To mitigate the health risks of harmful gases and fumes to operators, the device is equipped with a filter assembly 5. During welding, the motor-driven cooling fan 59 inside the mounting bracket 58 is activated. The fan's rotation generates negative pressure, drawing in the welding fumes and harmful gases generated above the welding platform 1 through the collection hood 512. The fumes and gases then enter the connecting pipe 54 and are filtered and purified by the activated carbon adsorption filter element 55. The clean air is then discharged through the protective filter cover 57. The annular insert plate 511 at the bottom of the protective filter cover 57 is slidably connected to the annular insertion groove 56 at the top of the connecting pipe 54, ensuring the stable installation of the protective filter cover 57. With its ease of disassembly, it facilitates regular cleaning or replacement of the activated carbon adsorption filter element 55, thereby maintaining the air quality of the welding environment and ensuring the health and safety of operators. When it is necessary to change the position of the sootblower frame components, the position of the positioning angle iron 3 needs to be adjusted. At this time, the connecting column 49 is rotated in the opposite direction so that the snap-fit ​​block 411 and the connecting groove 47 are on the same horizontal line. At this time, the spring 44 returns to its original position and pushes the pressing block 45 upward, pushing the snap-fit ​​block 411 out of the positioning hole 41, thus completing the disassembly of the positioning angle iron 3. Then, the installation steps of the positioning angle iron 3 are repeated as needed to complete the installation of the positioning angle iron 3.
