Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel structure building technology, and in particular relates to a fire-resistant device for high-altitude welding of steel structures. Background Technology
[0002] In high-altitude welding operations on steel structures, specialized protective devices, through specific structural designs such as fire catchers, hangers, fixing mechanisms, and anti-spatter components, can effectively catch welding slag and sparks generated during the welding process, preventing them from falling and causing fires, burns to personnel, or damage to equipment below. These devices are characterized by easy installation and fixation, adaptability to complex high-altitude environments, and improved welding operation safety. They can intercept and collect spatter during high-altitude welding of steel structures, reducing safety hazards and ensuring the safe and orderly conduct of construction.
[0003] In high-altitude welding operations on steel structures, slag collection hoppers are crucial for preventing the risk of slag splashing. However, in practical applications, the slag-collecting material inside the hopper is easily affected by airflow in the high-altitude working environment, sometimes being blown away or shifted. Once the material detaches from the hopper, the slag directly contacts the metal hopper body, potentially damaging it due to high temperatures and reducing its lifespan. This can also pose safety hazards such as burns to personnel below or damage to equipment. Therefore, we need to design a slag-collecting device to prevent slag splashing during high-altitude welding of steel structures. This device should firmly lock the material in place, resist interference from high-altitude airflow, prevent its shifting or falling, and allow the slag to be buffered by the material, preventing direct impact on the metal hopper body. This extends the hopper's lifespan, reduces replacement costs, and ensures stable slag collection, eliminating safety hazards caused by material shifting and protecting personnel below.

[0025] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model.

In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.
[0026] The accompanying drawings in this specification are schematic diagrams used to illustrate the concept of this utility model, and schematically show the shapes of the various parts and their interrelationships. Please note that, in order to clearly show the structure of the components of the embodiments of this utility model, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.
[0027] Example 1: Figure 1 This invention illustrates a steel structure high-altitude welding splash-proof fire-catching device according to an embodiment of the present invention. It includes two symmetrical support columns 1. A crossbeam 2 is fixedly connected to one side of each support column 1 facing each other. A movable slide 3 is provided on the surface of the crossbeam 2. A fire-catching bucket 4 is fixedly connected to the bottom of the movable slide 3. L-shaped support plates 5 are bolted to both sides of the fire-catching bucket 4. The top of the fire-catching bucket 4 is bolted to the L-shaped support plates 5. L-shaped blocks 6 are provided on both sides of the fire-catching bucket 4. Multiple rectangular grooves 7 are formed in the inner cavity of the L-shaped blocks 6. Two symmetrical circular grooves 8 are formed on the top of the L-shaped blocks 6. The bottom of the inner cavity of the two circular grooves 8 is welded to the bottom end of a triangular block 12. Multiple rectangular grooves 7 have sliding blocks 9 slidably connected to their inner cavities. Two symmetrical connecting blocks 11 are provided on the top of the multiple sliding blocks 9. A crossbar 10 is fixedly connected to the top of the two sliding blocks 9. The two crossbars 10 are fixedly connected to the two ends of the connecting blocks 11. A triangular block 12 is provided on the top of the two connecting blocks 11. Multiple rectangular plates 13 are fixedly connected to the left and right sides of the two connecting blocks 11 and the triangular blocks 12 by bolts. A screw 14 is rotatably connected to the central axis at the top of the L-shaped block 6. The triangular block 12 moves on the surface of the screw 14. A connecting rod 15 is fixedly connected to the bottom of the side of the triangular block 12 away from the L-shaped block 6. Round blocks 18 are attached to the four corners of the bottom of the inner cavity of the fire-receiving bucket 4.
[0028] The above solution involves placing the fire-receiving cloth inside the fire-receiving hopper 4. Through the coordinated use of the screw 14, the fixed seat 16, and the upright rod 17, the upright rod 17 drives the round block 18 to press the four corners of the top of the fire-receiving cloth. This causes the sliding block 9 and the connecting block 11 to move in coordination with the triangular block 12 for adjustment. This solution has the advantages of locking the cloth inside the fire-receiving hopper, resisting interference from high-altitude airflow to prevent displacement and falling off, using the cloth to buffer the impact of welding slag, protecting the metal hopper body and extending its service life.
[0029] Example 2: Reference Figure 4 The front and rear ends of the connecting rod 15 are fixedly connected to two symmetrical fixed seats 16.
[0030] The above solution is adopted: by setting the fixed seat 16, the fixed seat 16 is connected to the connecting rod 15, the upright rod 17 and the round block 18 to provide reliable positioning and support for the fire receiving bucket 4, effectively limiting the displacement and shaking of the fire receiving bucket 4 caused by external forces such as wind, and ensuring the stability of the cloth fire receiving area.
[0031] Example 2: Reference Figure 5 A spring washer 19 is fitted on the surface of the screw 14. The screw 14 is fixedly connected to the triangular block 12 and the L-shaped block 6 by two nuts respectively. The spring washer 19 fits tightly with the L-shaped block 6, the triangular block 12 and the nuts.
[0032] The above solution is adopted: by setting the spring washer 19, the friction between the threads is increased, which further prevents the bolt from rotating and loosening. The spring washer has its own elasticity. After being compressed during installation, it continues to rebound, providing continuous axial tension to the screw 14 and the nut. The small displacement caused by wind load prevents the threaded connection from loosening.
[0033] Example 2: Reference Figure 5 A spring 20 is provided in the inner cavity of the rectangular groove 7. The two ends of the spring 20 are welded to the bottom of the inner cavity of the rectangular groove 7 and the bottom of the connecting block 11, respectively.
[0034] The above solution is adopted as follows: By setting the spring 20, when the triangular block 12 moves on the surface of the screw 14, the spring 20 can elastically deform. When the round block 18 presses the fire cloth, the triangular block 12 presses the connecting block 11 onto the top of the L-shaped block 6. Then, when the round block 18 releases the fire cloth, the triangular block 12 adjusts upward on the surface of the screw 14, the spring 20 can be reset, the triangular block 12 adjusts upward, and the round block 18 releases the pressure on the cloth, thus improving the stability of the triangular block 12 during adjustment.
[0035] Working Principle: When this utility model is in use, the steel structure high-altitude welding anti-splash fire-catching device consists of a support column 1 and a crossbeam 2 forming a stable frame. The movable slide 3 can slide along the crossbeam 2. The fire-catching hopper 4 is installed below the crossbeam 2 via the movable slide 3. First, the fire-catching cloth is laid into the inner cavity of the fire-catching hopper 4. Then, the screw 14 is rotated, and the threaded transmission of the screw 14 causes the triangular block 12 to move axially along the screw 14. The triangular block 12 drives the fixed seat 16 and the upright 17 to move down synchronously through the connecting rod 15. The upright 17 pushes the bottom round block 18 to precisely press the four corners of the fire-catching cloth. During this process... When the triangular block 12 moves down, its inclined surface contacts the connecting block 11, forcing the connecting block 11 to drive the sliding block 9 to slide along the rectangular groove 7 of the L-shaped block 6. The sliding block 9 moves to compress the spring 20. With the elastic deformation of the spring 20, the connecting block 11 is tightly attached to the top of the L-shaped block 6, realizing the top four corners of the fire-fighting cloth are locked by hard pressure clamping, resisting the interference of high air flow and preventing displacement. If the fire-fighting cloth needs to be replaced, the screw 14 is rotated in the opposite direction, the triangular block 12 moves up, the spring 20 rebounds and drives the connecting block 11 and the sliding block 9 to reset, and the round block 18 releases the pressure on the four corners of the cloth, so that it can be quickly replaced.
[0036] In summary, this steel structure high-altitude welding anti-splash fire-catching device, by placing the fire-catching cloth inside the fire-catching hopper 4, and through the coordinated use of the screw 14, the fixing seat 16 and the upright 17, causes the upright 17 to drive the round block 18 to press down the four corners of the top of the fire-catching cloth. Subsequently, the sliding block 9 and the connecting block 11 will adjust in coordination with the movement of the triangular block 12. It has the advantages of locking the cloth inside the fire-catching hopper, resisting interference from high-altitude airflow and preventing displacement and falling off, using the cloth to buffer the impact of welding slag, protecting the metal hopper body and extending its service life.
[0037] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
