Detailed Implementation

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0019] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Please see the appendix Figure 1 - Appendix Figure 5The present invention discloses a welding device for I-beam steel structures, comprising a main body 1, the main body 1 including a grinding component 3 and a transmission component 7 connected to the grinding component 3. The grinding component 3 includes a rotating ring 31, and two vertical frames 32 are fixedly arranged on the top surface of the rotating ring 31. Lifting rods 33 are fixedly arranged inside the two vertical frames 32, and grinding heads 34 are welded to the top surface of the two lifting rods 33. The transmission component 7 includes a motor 71, a turntable 72 and a receiving ring 73. The motor 71 is fixedly connected to the turntable 72, and the motor 71 and the turntable 72 are rotatably connected through a rotating shaft. The receiving ring 73 is fixedly arranged on the turntable 72.

[0021] In Embodiment 1, a desktop component 2 is fixedly installed on the upper surface of the main body 1. The desktop component 2 includes a base 21. Collection grooves 22 are provided on both sides of the surface of the base 21. A middle groove 23 is provided in the middle of the base 21. Fixing blocks 24 are fixedly installed on both sides of the base 21. Telescopic rods 25 are fixedly connected to both sides of the fixing blocks 24. Push plates 26 are fixedly installed at the ends of the two telescopic rods 25. The length of the push plates 26 is the same as the length of the collection grooves 22. The grinding head 34 is telescopically set. A pull-out groove 4 is provided on the bottom surface of the base 21. A base 5 is slidably connected inside the pull-out groove 4. Specifically, the turntable 72 is driven to rotate by the motor 71, and the turntable 72 drives the receiving ring 73 to rotate. Since the receiving ring 73 is connected to the rotating ring 31, it drives the rotating ring 31 and the grinding assembly 3 on top to rotate at multiple angles. The grinding head 34 performs all-round grinding on the weld seams and surrounding areas of the steel structure. The metal dust generated during the grinding process slides down the inclined groove wall of the collection groove 22 under the action of the push plate 26 and falls into the collection frame 6 below. The collection frame 6 collects the dust, thereby realizing the flexible rotation grinding of the I-shaped steel structure. At the same time, it meets the integrated requirements of flexible rotation grinding, all-area dust control, and rapid dust removal and maintenance for on-site steel structure grinding.

[0022] In the second embodiment, a collection frame 6 is fixedly connected to both sides of the base 5, and the collection frame 6 corresponds to the collection groove 22. The receiving ring 73 is fixedly connected to the rotating ring 31. The height of the rotating ring 31 is flush with the base 21, and there is no gap between the rotating ring 31 and the base 21. A controller is fixedly installed on the front of the main body 1. The controller is electrically connected to the telescopic rod 25, the lifting rod 33 and the motor 71 respectively. Specifically, through the coordinated operation of the grinding component 3 and the transmission component 7, flexible rotation grinding of the I-beam steel structure is achieved. The rotating ring 31 and the receiving ring 73 are meshed and connected, and under the drive of the motor 71, they can rotate at multiple angles, driving the grinding head 34 to rotate in all directions. Grinding operations on welds in different parts can be completed without frequent adjustments to the placement of the steel structure, greatly improving grinding flexibility and efficiency. The lifting rod 33 can flexibly adjust the height of the grinding head 34, and the telescopic grinding head 34 can adapt to grinding welds of different depths, further expanding the equipment's adaptability range, especially suitable for operation needs in complex scenarios such as high altitudes and confined spaces.

[0023] Specifically, the combination of the collection trough 22 and the collection frame 6 enables comprehensive dust control. Metal dust generated during the grinding process slides into the collection frame 6 through the collection trough 22, effectively preventing dust diffusion and protecting the working environment and the health of operators. The pull-out base 5 design eliminates the need to disassemble multiple parts for dust cleaning. Dust removal can be completed simply by pulling out the base 5 or opening the sealing cover, achieving rapid dust removal and maintenance and improving work efficiency.

[0024] Specifically, the fixing mechanism of the desktop component 2 achieves stable fixation of the I-beam steel structure. The telescopic rod 25 can be flexibly adjusted according to the width of the steel structure. The push plate 26 is in full contact with the steel structure, and the anti-slip texture increases the friction, which can effectively prevent the steel structure from shifting during the grinding process and ensure the grinding accuracy. The push plate 26 is made of wear-resistant rubber material, which avoids scratching the surface of the steel structure and improves the processing quality. The setting of the guardrail further enhances the safety of operation and prevents operators from accidentally contacting the grinding head 34.

[0025] Specifically, the touch controller integrates the control functions of each component, making it easy to operate, highly automated, and reducing human error. The components are rationally designed, easy to disassemble and maintain, and have a long service life. It can meet the needs of diverse grinding scenarios on site and has high practicality and market application value.

[0026] Specifically, the vertical frame 32 is fixed vertically to the top surface of the rotating ring 31, and the two vertical frames 32 are symmetrically distributed on both sides of the central axis of the rotating ring 31; the lower end of the lifting rod 33 is fixedly connected to the inner wall of the vertical frame 32, the upper end of the lifting rod 33 extends to the outside of the vertical frame 32, and the grinding head 34 is welded to the upper end face of the lifting rod 33, with the grinding ends of the two grinding heads 34 arranged opposite each other.

[0027] Specifically, the collection troughs 22 are symmetrically opened on both sides of the upper surface of the base 21. The walls of the collection troughs 22 are inclined, and the bottom of the troughs is inclined downward towards the collection frame 6. The middle trough 23 runs through the upper and lower surfaces of the base 21. The inner diameter of the middle trough 23 is adapted to the outer diameter of the rotating ring 31. The fixing block 24 is vertically fixed to the upper surface of the base 21. The telescopic rod 25 is horizontally set. Its fixed end is welded to the side wall of the fixing block 24, and its telescopic end is fixedly connected to the side wall of the push plate 26.

[0028] Specifically, the pull-out groove 4 is horizontally opened along the length of the base 21, and the inner wall of the pull-out groove 4 is provided with a slide rail. The two sides of the base 5 slide in cooperation with the slide rail. The upper opening of the collection frame 6 corresponds vertically to the lower outlet of the collection groove 22. The side wall of the collection frame 6 is welded and fixed to the side wall of the base 5. The body of the motor 71 is fixedly connected to the upper surface of the turntable 72. The output shaft of the motor 71 is coaxially fixed to the center of the turntable 72. The receiving ring 73 is coaxially fixed to the top surface of the turntable 72. The top surface of the receiving ring 73 is fixedly connected to the bottom surface of the rotating ring 31.

[0029] Working principle: Firstly, when using this I-beam steel structure welding device for grinding, start the equipment via the controller. Based on the width of the I-beam steel structure, operate the controller to extend the telescopic rod 25, pushing the push plate 26 towards the steel structure until it makes tight contact with the flange plate. The anti-slip texture on the inner side of the push plate 26 increases friction, achieving stable fixation of the steel structure. After fixation, adjust the height of the lifting rod 33 via the controller according to the height and position of the weld. Using the scale markings on the surface of the lifting rod 33, adjust the grinding head 34 to a suitable height. Adjust the telescopic length of the grinding head 34 according to the weld depth to ensure precise alignment with the weld. The position is set by the controller to set the rotation speed of the grinding head 34 and the rotation mode of the rotating ring 31 to rotate at a constant speed or intermittently. The motor 71 and the grinding head 34 are started. The motor 71 drives the turntable 72 to rotate. The turntable 72 drives the receiving ring 73 to rotate. The receiving ring 73 meshes with the gear of the rotating ring 31 through the gear ring, driving the rotating ring 31 and the grinding assembly 3 on the top to rotate at multiple angles. The grinding head 34 performs all-round grinding on the weld seam and surrounding area of ​​the steel structure. The metal dust generated during the grinding process slides down the inclined groove wall of the collection groove 22 into the collection frame 6 below under the action of the push plate 26. The operator can observe the amount of dust collected in real time through the transparent observation window on the side of the collection frame 6. When fine grinding is required on welds in different parts, the rotation angle and speed of the rotating ring 31 can be adjusted by the controller, or the height of the lifting rod 33 and the extension length of the grinding head 34 can be adjusted to achieve precise grinding and ensure grinding quality. During the grinding process, the operator can monitor the equipment operating parameters through the display screen of the controller. If an emergency occurs, the emergency stop button can be pressed immediately to stop the equipment operation. Finally, after the grinding operation is completed, the grinding head 34 and motor 71 are turned off by the controller, the telescopic rod 25 is adjusted to retract, the push plate 26 is released, and the ground I-shaped steel structure is taken out. When the dust in the collection frame 6 accumulates to a certain amount, the handle at the front end of the base 5 can be pulled to pull the base 5 out along the slide rail of the pull-out groove 4, and the collection frame 6 can be taken out for cleaning. Alternatively, the collection frame 6 can be opened directly to discharge the dust. After cleaning, the collection frame 6 is put back in its original position, and the base 5 is pushed into the pull-out groove 4 to start the next operation. The entire operation process realizes the integration of flexible rotation grinding, full-area dust control and rapid dust cleaning and maintenance. It is convenient, safe and efficient to operate, and adaptable to I-shaped steel structures of different specifications and complex operation scenarios. At this point, the entire workflow is completed.
