Description

Technical Field

[0001] This utility model relates to a fire collection basin for welding wet joints of bridges used in highway and municipal projects. Specifically, it relates to a sliding fire collection basin for welding wet joints of bridges, which is mainly used to collect welding slag or sparks generated during the welding process of wet joints of bridges, so as to ensure fire safety during the welding process. It belongs to the field of construction safety protection technology. Background Technology

[0002] As is well known, welding is essential in construction, including welding reinforcing bars, steel beams, formwork, scaffolding, and T-beams. During welding, molten metal and welding flux inevitably splatter, creating welding sparks. If welding is done on the ground, these sparks have little impact. However, as buildings rise, especially high-rises, welding sparks falling from heights present several challenges. First, welding at heights results in a wider area of ​​scattering sparks, and they may be blown away by the wind to areas far from the work site, increasing the risk of injury. Firstly, sparks increase the possibility of fire. Secondly, sparks falling on workers on lower floors or passersby can cause burns, fires, or other serious consequences, potentially leading to workplace injuries. Thirdly, sparks falling on construction equipment or tools can damage them. The equipment itself requires high levels of maintenance and protection, and the lack of a fire pit to collect sparks can cause burns to the equipment surface, increasing the equipment failure rate and affecting work progress. Fourthly, sparks falling on flammable materials can cause fires. Sparks generated during welding can scatter and splash onto surrounding flammable materials such as wood, paint, and fabric. Without a fire basin to collect sparks, they may fall to the ground or nearby buildings, causing a fire; fifth, environmental pollution: sparks and metal particles generated during welding may pollute the environment, especially without a fire basin, where scattered metal particles may spread in the air and even pollute the environment below; sixth, poor cleanliness: if welding sparks and spatter are not collected in time, they may affect the cleanliness of the working environment, resulting in unclean equipment and work surfaces, further affecting the safety of the operation; seventh, reduced work efficiency: to avoid accidents caused by falling sparks, workers may need to frequently stop to check, or even suspend work, which will prolong the working time and reduce work efficiency; eighth, because many fire basins are used at height, there is no special structure for lifting them during installation, so installation or dismantling relies on construction personnel to do it directly. For heavier fire basins, at least two operators are needed to install or dismantle them, which is time-consuming, labor-intensive, and poses safety risks. In short, it is often very inconvenient.

[0003] In recent years, with the rapid development of highway construction, the ratio of bridges to tunnels on highways has been increasing in order to reduce land waste, and T-beam bridges account for a large proportion of bridge designs. However, bridge projects are located in forest areas, where welding operations are prone to slag falling and posing a fire hazard. Traditional fire catchers are difficult to install, not very practical, and workers are reluctant to use them. They are also inconvenient to move, and most workers will avoid using them for various reasons such as carrying them inconveniently and preventing fires during use, which often leads to safety accidents.

[0004] This project, Section A of the East Third Ring Road, includes 7 bridges with a total of 108 spans, comprising 78 spans of small box girders and 30 spans of steel box girders. It also involves 456 precast small box girders and 30 precast steel box girders. There are 380 wet joints on the bridge deck, totaling 75,000 welded joints, posing a fire hazard. Due to the construction requirement of spot welding the reinforcing bars before full welding during the wet joint welding process, traditional fire-resistant basins are blocked by the reinforcing bars at the wet joints and cannot move with the welding work, making them unusable. Therefore, a sliding fire-resistant basin with a different structure was designed to achieve efficient protection against welding flames.

[0005] A search revealed that Chinese utility model patent CN211162520U discloses a fire-receiving bucket, comprising: an adjustable-length support rod; a pair of pulleys fixed to opposite ends of the support rod and capable of braking, wherein the pulleys are positioned on the top surface of the steel section to be welded by adjusting the length of the support rod to fit the width of the steel section to be welded; and a fire-receiving basin forming an accommodating space, wherein hanging rods are connected to opposite sides of the fire-receiving basin, and a pair of hanging rods are correspondingly connected to opposite ends of the support rod, and the fire-receiving basin is hung on the bottom of the steel section to be welded. While this design can solve the technical problem of excessive distance between the fire-receiving basin and the welding point in existing technologies, leading to welding sparks easily splashing outside the fire-receiving basin after the welding position is moved, posing a safety hazard, the fire-receiving bucket also suffers from complex structure, large footprint, requiring a large operating space, small fire and slag collection range, and inconvenient operation, requiring at least two operators to work together. In short, it is often very inconvenient.

[0006] Therefore, the key to solving the above-mentioned technical problems lies in developing a sliding fire-receiving basin for welding wet joints of bridges that is both safe and practical. Summary of the Invention

[0007] In view of the many defects and deficiencies existing in the above-mentioned background technology, this utility model has made improvements and innovations. The purpose of this invention is to solve the problem that the traditional fire-receiving basin is inefficient to move during the welding process of wet joints in bridges, and cannot move quickly with the welding operation, which causes the fire safety hazard caused by falling welding sparks. This utility model achieves efficient protection of welding sparks by setting fixed devices at both ends of the wet joint of the bridge construction, hanging steel wire ropes and tightening them, and setting pulleys at the four corners of the upper end of the fire-receiving basin so that it can move on the steel wire ropes.

[0008] Another objective of this invention is the provision of a limiting component on the fire-receiving basin. This limiting component not only limits the position of the fire-receiving basin but also allows for its traction. The limiting function effectively prevents the fire-receiving basin from shifting or tilting due to wind, vibration, or improper human operation during high-altitude operations. The traction function allows for convenient adjustment of the fire-receiving basin's position, enabling operators to quickly move it to the desired location. This makes high-altitude welding operations safer, more reliable, and more efficient.

[0009] Another objective of this invention is to facilitate the hoisting, handling, and positioning of the fire basin by symmetrically arranging lifting rings on either side of the upper opening of the fire basin. This ensures even force distribution during hoisting, preventing tilting or swaying due to uneven hoisting and thus improving stability during the hoisting process. It also helps to precisely control the suspension position of the fire basin, ensuring its balance and stability during hoisting, reducing human error, preventing tilting or swaying, and ensuring the fire basin remains in the predetermined position. The symmetrical design of the lifting rings simplifies the hoisting process. Operators can quickly and effectively lift and fix the fire basin in the appropriate position without complex adjustments and measurements, reducing operation time.

[0049] The two ends of the hoisting rope (4) are fixed by locking clips (8) after passing through the hoisting rope connection holes of the adjusting rod (31) on the same side; and hoisting rings (11) are symmetrically connected to each other on any opposite sides of the upper opening of the fire basin (1) for easy installation and removal of the fire basin (1).

[0050] The working principle is as follows: Before using the sliding fire basin for welding wet joints of bridges with the above-mentioned design structure, the fire basin of this design structure that has been manufactured needs to be taken to the construction site for corresponding installation as a backup.

[0051] Before installation, operators only need to move or hoist the already manufactured sliding fire basin of this design to the designated construction location using appropriate handling equipment or manually, and place it for installation.

[0052] During installation, the operator only needs to first install the four pre-prepared clamps (3) symmetrically in pairs at the ends of two adjacent T beams. Specifically, the upper clamp (32) and lower clamp (33) are snapped together and connected to the flange at the end of one of the box beam flanges (6). After the installation is secure and reliable, the upper clamp (32) and lower clamp (33) are locked and fixed with adjusting locking parts (34). The same installation method is used to complete the installation of the other three clamps (3). After the four clamps (3) are installed and secure, one of the operators uses a pre-prepared rope or hoisting rope to hoist the fire basin (1) and install it. After one operator smoothly hoists the fire basin (1) with the hoisting rope, another operator... Personnel then symmetrically pass the two suspension ropes (4) through the four pulley devices (2) set at the upper opening of the fire basin (1). During the installation process, it is necessary to ensure that the fire basin (1) is safely and stably installed on two of the suspension ropes (4). Then, the two suspension ropes (4) suspending the fire basin (1) are connected to the same axis and installed on the same side on the two corresponding clamps (3) at both ends of the box girder wing plate (6), so that the fire basin (1) is just locked and located in the wet joint of the end T beam in the middle of the two box girder wing plates (6). After the installation is stable and reliable and the tension of the two suspension ropes is adjusted, the ends of the two suspension ropes (4) are fixed with locking clamps (8). After the fixation is stable and reliable, the installation work of this utility model is completed. After the installation work is completed, it can be used.

[0053] Before using this utility model, the operator needs to first check the position of the fire basin (1) and ensure that the fire basin (1) is located directly below the steel bar (7) to be welded at the wet joint of the T beam to be welded. This serves as a protective function and also allows for the centralized collection of spark welding slag (91) without leakage, preventing the spark welding slag (91) from falling out of the fire basin (1). During the installation and use process, the two suspension ropes (4) are used as the component structure for the fire basin (1) to achieve stable and reliable displacement or walking suspension. After ensuring that the fire basin (1) is installed securely and reliably, the fire basin (1) can be used normally.

[0054] When in use, the operator only needs to use the pre-prepared welding equipment (9) to weld the T-beam wet joint welded steel bars (7) that need to be welded. During the welding of the above-mentioned T-beam wet joint welded steel bars (7), the operator can use the on-site bar-shaped steel bars or other on-site construction tools to push or pull or move the inner side wall of the fire basin (1) forward according to the actual needs, thereby simultaneously moving the fire basin (1) back and forth, so as to realize the welding operation of the T-beam wet joint welded steel bars (7) at different positions in a time-saving and labor-saving manner. During welding, the spark slag (91) falls freely downward due to the action of gravity and falls into the fire basin (1), so as to realize the centralized and unified collection of the spark slag (91).

[0055] Finally, as time goes on, after all the welding work is completed, one of the operators uses a pre-prepared rope or hoisting rope to pass through the hoisting ring (11) set on the fire basin (1) and lifts the fire basin (11). Then, another operator removes the four clamps (3) installed on the box girder flange (6). When removing the clamps (3), the operator first needs to loosen the adjusting locking part (34) located on the adjusting rod (31) to separate the upper clamp (32) and lower clamp (33) from the flange at the end of the box girder flange (6) and remove the upper clamp (32) and lower clamp (33) from the flange. Remove and separate the adjusting rod (31). Then, the operator opens each locking clamp (8) and pulls the two lifting ropes (4) from both ends of the fire basin (1) to separate them from the fire basin (1). At the same time, the operator collects and organizes the two lifting ropes (4). Then, the fire basin (1) is hoisted to the designated position by the hoisting rope. The spark welding slag (91) in the fire basin (1) is poured out. After cleaning and repairing the fire basin (1), the cleaned fire basin (1) together with the other parts of this utility model is transported to the designated tool storage warehouse for stacking and storage for the next recycling.

[0056] Throughout the entire implementation process described above, operators can prepare multiple fire-receiving basins of this utility model design for installation and use, depending on the actual construction project needs or the number of welders.

[0057] The beneficial effects of this utility model compared with the prior art are:

[0058] 1. This utility model has a novel design and simple structure. It solves the problem of low moving efficiency of traditional fire basins during the welding process of wet joints in bridges. The fire basins cannot move quickly with the welding operation, which causes the fire safety hazard caused by falling welding sparks. This utility model sets a fixed device at both ends of the wet joint of the bridge construction, hangs a steel wire rope and tightens it, and sets pulleys at the four corners of the fire basin to move on the steel wire rope. This achieves efficient protection of the welding sparks by the fire basin. This utility model can complete the welding work of a section of T-beam wet joint steel bars with one installation. It solves the time and construction efficiency costs caused by the traditional need to install, disassemble or move the fire basin multiple times.

[0059] 2. This utility model features a limiting component on the fire-receiving basin. This limiting component can both limit the position of the fire-receiving basin and pull it. The limiting function effectively prevents the fire-receiving basin from shifting or tilting due to wind, vibration, or improper human operation during high-altitude operations. The pulling function allows for convenient adjustment of the position of the fire-receiving basin, enabling operators to quickly move it to the desired location. This makes high-altitude welding operations safer, more reliable, and more efficient.

[0060] 3. This utility model can not only improve the positional stability of the fire-receiving basin and ensure the effective collection of sparks and welding slag, thereby improving the safety and efficiency of welding operations, but also reduce equipment wear, improve the cleanliness of the working environment, and reduce the risks of manual operation;

[0061] 4. The limiting component of this utility model can ensure that the fire basin is always kept in the predetermined position, reduce the safety hazards caused by the displacement of the fire basin, and prevent sparks or welding slag from splashing out and causing fire or injury; at the same time, it also reduces the risk of accidents and solves the problem that welding sparks may not be effectively collected when the fire basin is moved, which may even cause fire or injury. The limiting component can ensure the accuracy of the fire basin position, thereby reducing the risk of accidents.

[0062] 5. The limiting component of this utility model also has a traction function, which enables convenient adjustment of the position of the fire basin. When working at height, the operator can use the traction function to quickly move the fire basin to the required position, reducing the manual operation steps of frequently adjusting the fire basin, saving time and improving work efficiency; it can easily adjust the position of the fire basin to ensure that it is always below the welding area, avoiding the inability to collect sparks or affect the welding quality due to an unsuitable position of the fire basin.

[0063] 6. This utility model achieves continuous positioning due to the setting of the limiting component, which integrates the limiting and traction functions into one, so that the fire-receiving basin can always be kept in the correct position in the welding operation area, ensuring that the sparks and welding slag generated during the welding process can effectively fall into the fire-receiving basin, preventing the sparks from flying around, reducing the risk of fire, achieving precise spark collection, and ensuring that the fire-receiving basin can be precisely limited to the appropriate position, so as to maximize the collection of splashing sparks and avoid splashing sparks from polluting the surrounding environment or causing accidents.

[0064] 7. The use of the limiting component in this utility model also reduces frequent adjustments and maintenance. The limiting component can prevent the fire basin from being frequently adjusted or collided, reducing equipment damage or overuse caused by improper fire basin positioning, and lowering maintenance costs. It also reduces equipment wear and extends the service life of the fire basin and its components.

[0065] 8. This utility model features symmetrically arranged lifting rings at the upper opening of the fire basin, facilitating its lifting, handling, and positioning. This ensures even force distribution during lifting, preventing tilting or swaying due to uneven lifting, thus improving stability during the lifting process. It also helps to precisely control the hanging position of the fire basin, ensuring its balance and stability during lifting, reducing human error, preventing tilting or swaying, and ensuring the fire basin remains in the predetermined position. The symmetrical design of the lifting rings simplifies the lifting process. Operators can quickly and effectively lift and fix the fire basin in the appropriate position without complex adjustments and measurements, reducing operation time.

[0066] 9. Since pulleys are installed at the four corners of the fire-receiving basin and attached to the wire rope, the pulleys are used to move the fire-receiving basin to the hot work position as the welder works during the welding process. This can effectively catch welding slag and sparks. Guiding the pulleys of the fire-receiving basin to the appropriate position can catch welding slag and sparks in time, preventing them from scattering to unsafe places and reducing the risk of fire.

[0067] 10. This utility model can prevent welding slag accumulation: If welding slag is not properly treated, it is easy to accumulate in the working environment, increasing the risk of accidents. The pulley system can move continuously during the welding operation to prevent welding slag accumulation, thereby maintaining the cleanliness and safety of the workplace.

[0068] 11. This utility model can adapt to different welding scenarios. Through the installation of pulleys, the fire-receiving basin can be flexibly moved to different welding positions according to the different needs of the welding operation, meeting the operational requirements of different heights, angles, and directions. This flexibility allows welding operations to be carried out efficiently in various environments, ensuring the smooth completion of the welding process.

[0069] 12. In this utility model, before welding the reinforcing bars, the clamps are used to clamp the two end flanges of the small box girder, and the steel wire rope is passed through and tightened. The fire-receiving basin pulley is installed on the steel wire rope. During the welding process, as the welder works, the fire-receiving basin is moved to the position where the reinforcing bars are welded.

[0070] 13. This utility model features a clamp for holding the steel wire rope of the fire-receiving basin, preventing slippage or loosening. The clamp firmly holds the steel wire rope, preventing the fire-receiving basin from slipping or loosening due to vibration or changes in tension during welding. This ensures that the fire-receiving basin remains in the correct position, effectively catching welding slag and sparks.

[0071] 14. The clamp of this utility model can improve safety. The clamp's fixing function can prevent the fire-receiving basin from accidentally falling during operation, avoiding potential dangers to workers or equipment, and improving the overall safety of the operation. By fixing the steel wire rope with the clamp, the operator can easily control the height, angle, and direction of the fire-receiving basin as needed, so that it can better cooperate with the welding operation; it avoids the trouble of frequent repositioning due to loosening or instability, thereby saving time and energy and improving work efficiency; the stability of the clamp allows the welder to spend less time adjusting the position of the fire-receiving basin, thus focusing more on the welding work itself;

[0072] 15. Because the upper opening of the fire-receiving basin of this utility model is large, it is convenient to place or receive fire sources; the lower opening is smaller, which helps to concentrate flames or heat and improve the efficiency of use. The hollow internal structure can effectively accommodate combustibles or other heat sources, ensuring that the heat is concentrated and evenly distributed. This design not only enhances the stability of the structure, but also improves safety and ease of operation.

[0073] 16. Since the suspension rope (4) used in this utility model is made of fire-resistant and wear-resistant material, on the one hand, the suspension rope (4) made of fire-resistant and wear-resistant material has high temperature resistance and can withstand high heat for a long time without damage. In this way, even if the temperature at the bottom of the fire pit is high, the suspension rope can maintain its strength and stability, and avoid the suspension rope from breaking or deforming due to high temperature, thereby ensuring safety during use;

[0074] 17. The lifting rope made of fire-resistant and wear-resistant material is of great value for this invention. On the one hand, it can extend the service life. Compared with ordinary materials, fire-resistant materials have stronger durability and anti-aging ability. Especially when frequently exposed to high-temperature environments, it can significantly extend the service life of the lifting rope and reduce the need for frequent replacement of the lifting rope. The fire-resistant lifting rope can not only resist high temperature, but also has stronger tensile strength, which can effectively support the heavy fire pit and prevent accidents caused by insufficient material strength. When using the fire pit, users do not have to worry about the lifting rope being damaged by high temperature.

[0075] 18. All components of the utility model are coated with anti-rust paint and waterproof layer, which can prevent the fire basin from rusting and extend the service life of the entire fire basin. This achieves environmental protection and saves resources. At the same time, the exterior of the fire basin is coated with a self-luminous fluorescent material, which can clearly mark the location of the fire basin at night or in dark indoor or underground construction environments. This can effectively play a safety reminder role, improve visibility, make it easy for people to identify, increase safety in construction and life, and maximize the personal safety of construction personnel.

The pulley 22 is welded to the four corners of the opening of the fire basin 1 through the pulley connecting seat 21. The four pulley devices 2 are hung on the suspension rope 4 and are located at the bottom of the steel bars 7 to be welded at the wet joint of the T-beam.

[0113] Specifically, such as Figure 13 As shown, the pulley connecting seat 21 includes a "[" shaped connecting plate and "∧" shaped side plates symmetrically connected to both ends of the connecting plate;

[0114] The pulley 22 has an inwardly recessed rope groove circumferentially arranged in the middle.

[0115] Furthermore, such as Figure 14 and Figure 15 As shown, the clamp 3 includes:

[0116] Adjusting rod 31;

[0117] Upper clamping plate 32 is sleeved above adjusting rod 31;

[0118] The lower clamping plate 33 is sleeved below the adjusting rod 31;

[0119] Adjust the locking element 34, which is connected to the adjusting rods 31 at both ends of the upper clamping plate 32 and the lower clamping plate 33.

[0120] More specifically, such as Figure 14 and Figure 15 As shown, the adjusting rod 31 is a screw rod, and a rope connection hole is also provided through the lower end of the adjusting rod 31;

[0121] The upper clamping plate 32 is a square plate-shaped component, and a clamping plate connection port is provided through one corner of the upper clamping plate 32;

[0122] The lower clamping plate 33 and the upper clamping plate 32 have the same shape, structure and size;

[0123] The total number of the adjusting locking parts 34 is at least two, and the adjusting locking parts 34 are nuts adapted to the adjusting rod 31.

[0124] In this utility model, both the upper clamping plate 32 and the lower clamping plate 33 are made of 200x200mm steel sheets with a thickness of 3mm. A threaded adjusting rod 31 with a length of 500mm and a diameter of 20mm is passed through a hole in the middle of one corner. After being tightened with nuts at the top and bottom, it is clamped and fixed to the edge of the box girder wing plate 6. A hanging rope connection hole is provided at the lower end of the adjusting rod 31.

[0125] Furthermore, such as Figures 10 to 12 As shown, the fire basin 1 has a square or trapezoidal structure with an open top and a hollow interior, and the square or trapezoidal structure is larger at the top and smaller at the bottom.

[0126] The two ends of the hoisting rope 4 are fixed with locking clips 8 after passing through the hoisting rope connection holes of the adjusting rod 31 on the same side; and hoisting rings 11 are symmetrically connected to both sides of any opposite side at the upper opening of the fire basin 1 to facilitate the installation and removal of the fire basin 1.

[0127] In this utility model, the fire basin 1 is made of 2mm thin steel plate, cut and welded. The upper opening is 600*800mm, the lower basin bottom is 450x550mm, and the height is 300mm. The fire basin 1 is a square structure with an upper opening and a hollow interior. It is designed to be larger at the top and smaller at the bottom, and its shape is similar to a funnel.

[0128] In this utility model, the hanging rope 4 is a steel wire rope with a diameter of 5mm, which serves as the sliding track of the fire basin 1 and is connected to the clamp 3.

[0129] Meanwhile, the suspension rope 4 in this utility model is a steel wire rope made using fire-resistant and wear-resistant methods.

[0130] Before using the sliding fire basin for welding wet joints of bridges according to the above embodiment 1, the already manufactured fire basin of this design structure needs to be taken to the construction site for corresponding installation as a backup.

[0131] Before installation, operators only need to move or hoist the already manufactured sliding fire basin of this design to the designated construction location using appropriate handling equipment or manually, and place it for installation.

[0132] During installation, the operator first symmetrically installs the four pre-prepared clamps 3 in pairs at both ends of two adjacent T-beams. Specifically, the upper clamp 32 and lower clamp 33 are engaged and connected to the flange at the end of one of the box girder flanges 6. After the installation is secure and reliable, the upper clamp 32 and lower clamp 33 are locked in place using adjusting locking parts 34. The other three clamps 3 are installed in the same way. After the four clamps 3 are installed securely and reliably, one operator uses a pre-prepared rope or hoisting rope to hoist the fire basin 1 and install it. One operator holds the fire basin 1 securely with the hoisting rope, while another operator... The workers then symmetrically thread two suspension ropes 4 through the four pulley devices 2 located at the upper opening of the fire basin 1. During this installation process, it is necessary to ensure that the fire basin 1 is safely and stably installed on two of the suspension ropes 4. Then, the two suspension ropes 4 suspending the fire basin 1 are connected to the same axis and installed on the same side on the two corresponding clamps 3 at both ends of the box girder wing plate 6, so that the fire basin 1 is just locked and located in the wet joint of the end T beam in the middle of the two box girder wing plates 6. After the installation is stable and reliable and the tension of the two suspension ropes is adjusted, the ends of the two suspension ropes 4 are fixed with locking clamps 8. After the fixing is stable and reliable, the installation work of this utility model is completed. After the installation work is completed, it can be used.

[0133] Before using this utility model, the operator needs to first check the position of the fire basin 1, and ensure that the fire basin 1 is directly below the steel bar 7 to be welded at the wet joint of the T-beam. This serves as a protective function and also allows for the centralized collection of welding slag 91 without leakage, preventing the welding slag 91 from falling out of the fire basin 1. During the installation and use, the two suspension ropes 4 are used as structural components for the stable and reliable displacement or movement of the fire basin 1. After ensuring that the fire basin 1 is installed securely and reliably, it can be used normally.

[0134] In use, the operator only needs to use the pre-prepared welding equipment 9 to weld the T-beam wet joint welding steel bars 7. During the welding of the T-beam wet joint welding steel bars 7, the operator can use the on-site bar-shaped steel bars or other on-site construction tools to push or pull or move the inner side wall of the fire basin 1 forward as needed, thereby simultaneously moving the fire basin 1 back and forth. This allows for time-saving and labor-saving welding of the T-beam wet joint welding steel bars 7 at different locations. During welding, the spark slag 91 falls freely downwards due to gravity and falls into the fire basin 1, achieving centralized and unified collection of the spark slag 91.

[0135] Finally, as time progresses and all welding work is completed, one operator uses a pre-prepared rope or hoisting rope to lift the fire-receiving basin 1 through the hoisting ring 11 set on it. Then, another operator removes the four clamps 3 installed on the box girder flange 6. To remove the clamps 3, the operator first needs to loosen the adjusting locking element 34 located on the adjusting rod 31, thereby disengaging the upper clamp 32 and lower clamp 33 from the flange at the end of the box girder flange 6, and then remove the upper clamp 32 and lower clamp 33 from the adjusting rod. Remove and separate the rod 31. Then, the operator opens each locking clamp 8 and pulls the two lifting ropes 4 from both ends of the fire basin 1 to separate them. At the same time, the operator retrieves and organizes the two lifting ropes 4. Then, the fire basin 1 is hoisted to the designated position by the hoisting rope. The spark welding slag 91 in the fire basin 1 is then poured out. After cleaning and repairing the fire basin 1, the cleaned fire basin 1, together with the other components of this utility model, is transported to the designated tool storage warehouse for stacking and storage, for future recycling.

[0136] Throughout the entire implementation process described above, operators can prepare multiple fire-receiving basins of this utility model design for installation and use, depending on the actual construction project needs or the number of welders.

[0137] Example 2

[0138] This embodiment 2 is basically the same as embodiment 1, the only difference being that, Figure 5 and Figure 13 As shown, it also includes:

[0139] Limiting component 5 is symmetrically connected between two pulley devices 2 above one end of the fire basin 1.

[0140] Furthermore, the two suspension ropes 4 overlap with the limiting component 5.

[0141] Specifically, such as Figure 5 As shown, the limiting component 5 includes:

[0142] Limiting component 51 is connected to two pulley connecting seats 21 above one end of the fire basin 1;

[0143] Connecting rod 52, connecting rod 52 is connected between two limiting members 51;

[0144] The traction rope 53 has one end connected to the middle of the connecting rod 52;

[0145] Hook 54, hook 54 is connected to the other end of the traction rope 53;

[0146] The limiting component 5 is used to limit the range of motion of the pulley device 2 and prevent the fire basin 1 connected to it from exceeding the predetermined working area.

[0147] More specifically, such as Figure 5 and Figure 13 As shown, the limiting member 51 is connected to the outer side below the corresponding pulley connecting seat 21; the limiting member 51 includes:

[0148] Limiting connecting plate 511 is symmetrically connected to the outer side of the connecting plate below pulley connecting seat 21;

[0149] The limiting connecting seat 512 has one end rotatably connected between two limiting connecting plates 511 via a rotating shaft.

[0150] The limiting wheel 513 is rotatably connected to the other end of the limiting connecting seat 512, and the limiting wheel 513 has a limiting groove circumferentially provided in the middle.

[0151] Torsion spring 514, the middle part of torsion spring 514 is sleeved on the rotating shaft, one end of torsion spring 514 is in contact with the connecting plate below the pulley connecting seat 21, and the other end of torsion spring 514 is in contact with the middle part of the limiting connecting seat 512.

[0152] Furthermore, such as Figure 3 As shown, the connecting rod 52 is connected between two limiting connecting seats 512, and a connecting ring is provided in the middle of the connecting rod 52;

[0153] One end of the traction rope 53 is connected to the connecting ring in the middle of the connecting rod 52;

[0154] The hook 54 is used to hang the connected traction rope 53 on the steel bar 7 to be welded at the wet joint of the T beam.

[0155] The above-described design structure is used in the same way as in Embodiment 1. The only difference is that when it is necessary to move the fire-receiving basin 1, the operator only needs to pull the traction rope 53, the limiting wheel 513 disengages from the wire rope torsion spring 514, and moves the fire-receiving basin 1 forward; release the traction rope 53, the torsion spring 514 returns to its original position, and the limiting wheel 513 pushes upward against the wire rope, thereby restricting the position of the fire-receiving basin 1 and preventing it from easily slipping. Finally, after it is in position, the hook 54 is fastened to or hooked onto the existing steel bars of the T-beam. Other specific uses are the same as in Embodiment 1 and will not be repeated here. This invention features a limiting component on the fire-receiving basin. This component not only limits the position of the fire-receiving basin but also allows for its traction. The limiting function effectively prevents the basin from shifting or tilting due to wind, vibration, or improper human operation during high-altitude work. The traction function allows for easy adjustment of the basin's position, enabling operators to quickly move it to the desired location, making high-altitude welding operations safer, more reliable, and more efficient. The limiting component ensures the basin remains in the predetermined position, reducing safety hazards caused by basin misalignment and preventing fires or injuries from sparks or welding slag. It also reduces the risk of accidents, solving the problem that welding sparks may not be effectively collected when the fire basin is moved, which could even cause fires or injuries. The limiting component can ensure the accuracy of the fire basin's position, thereby reducing the risk of accidents. The limiting component also has a traction function, which allows for easy adjustment of the fire basin's position. When working at height, the operator can use the traction function to quickly move the fire basin to the required position, reducing the manual operation steps of frequently adjusting fire basin 1, saving time, and improving work efficiency. It can easily adjust the position of fire basin 1 to ensure that it is always below the welding area, avoiding the inability to collect sparks or affecting the welding quality due to an unsuitable position of fire basin 1.

[0156] Finally, it should be noted that the specific embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made to it.
