Description

Technical Field

[0001] This invention relates to a fire collection basin for welding wet joints of bridges in highway and municipal projects. Specifically, it relates to a multifunctional fire collection basin for welding wet joints of bridges, mainly used to collect welding slag or sparks generated during the welding process of wet joints of bridges, ensuring fire safety during the welding process, and 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 can 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 scattered sparks, workers may need to frequently stop for inspection, or even suspend work, which will prolong the operation time and reduce work efficiency; eighth, because many fire basins are used at height, there is no corresponding structure for lifting them during installation. Installation and dismantling rely on construction workers. For heavy fire-catching basins, at least two operators are needed to install or dismantle them, which is time-consuming, labor-intensive, and poses safety risks. Furthermore, traditional fire-catching basins are enclosed on all sides, open at the top, and closed at the bottom. While they can catch welding slag and sparks, they lack features for easy cleaning and collection, making emptying the basin time-consuming and laborious, requiring multiple cleanings. Finally, some existing fire-catching basins are too deep, while others are too shallow. During high-altitude operations, strong winds can cause welding sparks and slag to scatter everywhere, making the process 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 invention 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 fire-receiving bucket design can solve the technical problem in the prior art where the distance between the fire-receiving basin and the welding point is too large, and welding sparks easily splatter outside the fire-receiving basin after the welding position is moved, posing a safety hazard, the aforementioned fire-receiving bucket also suffers from complex structure, large footprint, requires a large operating space, has a small fire-receiving and slag-receiving range, is very inconvenient to operate, and requires at least two operators to cooperate in its use; in short, it is often very inconvenient.

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

[0007] To address the numerous defects and shortcomings of the aforementioned background technology, this invention has made improvements and innovations. The purpose of this invention is to solve the problem of low moving efficiency of traditional fire-receiving basins during the welding process of wet joints in bridge construction. These basins cannot move quickly with the welding operation, leading to fire hazards caused by falling welding sparks. This invention achieves efficient protection against welding sparks by installing fixed devices at both ends of the wet joint span in bridge construction, hanging and tightening steel wire ropes, and installing pulleys at the four corners of the upper end of the fire-receiving basin, which moves along the steel wire ropes. Simultaneously, the fire-receiving basin is equipped with a limiting component, which can both limit the position of the fire-receiving basin and provide 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 the basin to the desired location, making high-altitude welding operations safer, more reliable, and more efficient.

[0008] Another objective of this invention is to effectively divert welding slag and sparks by incorporating a flow guide plate, preventing them from directly contacting other components within the fire basin. This reduces the risk of equipment damage due to slag accumulation or excessive temperature, thereby extending the service life of the fire basin and other related equipment. Furthermore, the effective diversion of slag and sparks results in a cleaner welding area, promoting a better working environment for operators and preventing slag buildup from affecting welding quality, thus improving work efficiency. Simultaneously, the concentration of slag and sparks in the area diverted by the flow guide plate makes cleaning easier, allowing for quick removal of slag and maintaining a clean and efficient work area. The opening and closing door design of this invention allows the fire basin to be easily opened and closed, facilitating the removal of slag, sparks, and other residues. Operators can easily clean the inside of the fire basin, ensuring a clean welding environment and high-quality welding.

[0009] Another objective of this invention is to prevent injury from flying debris by incorporating a protective guide component: During welding, sparks, slag, and other materials may fly out. The lifting protective guide component can effectively block flying slag, reducing the risk of injury to operators; furthermore, the protective guide component can prevent the leakage of high-temperature gases and flames from the fire pit, reducing safety hazards caused by fire, especially in high-temperature and high-risk working environments.

[0010] Another objective of this invention is to provide wheels (15) under the fire basin (1), so that the fire basin can be easily moved between different positions, avoiding the problem that the fire basin is heavy and inconvenient to move, making it flexible and convenient to use, and minimizing the labor intensity of the operators.

[0011] Another objective of this invention is that the symmetrical arrangement of lifting rings on either side of the upper opening of the fire basin facilitates its lifting, handling, and positioning. This ensures uniform force distribution during lifting, preventing tilting or swaying due to uneven lifting and thus improving stability. It also helps to precisely control the hanging position of the fire basin, ensuring its balance and stability during lifting, reducing human error, and preventing tilting or swaying, 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.

The four corners of the bottom of the fire basin (1) are also connected to the traveling wheels (15).

[0063] The beneficial effects of this invention compared to the prior art are:

[0064] 1. This invention features a novel design and simple construction. 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 can cause fire hazards caused by falling welding sparks. This invention sets up fixed devices at both ends of the wet joint of the bridge construction, hangs steel wire ropes and tightens them, and sets pulleys at the four corners of the fire basins so that they can move on the steel wire ropes. This achieves efficient protection of the fire basins against welding sparks. This invention can complete the welding of a section of T-beam wet joint reinforcement with one installation, which solves the time and construction efficiency costs caused by the traditional method of installing, disassembling or moving fire basins multiple times.

[0065] 2. This invention 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.

[0066] 3. This invention 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;

[0067] 4. The limiting component of the present invention 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, and may even cause fire or injury. The limiting component can ensure the accuracy of the fire basin position, thereby reducing the risk of accidents.

[0068] 5. The limiting component of the present invention 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 located below the welding area, avoiding the inability to collect sparks or affect the welding quality due to an unsuitable position of the fire basin.

[0069] 6. The present invention achieves continuous positioning by setting the limiting component, integrating 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 splashed sparks and avoid splashed sparks from polluting the surrounding environment or causing accidents.

[0070] 7. The use of the limiting component of this invention also reduces frequent adjustments and maintenance. The limiting component can prevent the fire basin from being frequently adjusted or collided, reduce equipment damage or overuse caused by improper fire basin position, reduce maintenance costs, reduce equipment wear, and extend the service life of the fire basin and its components.

[0071] 8. This invention, with its symmetrically arranged lifting rings at the upper opening of the fire basin, facilitates the lifting, handling, and positioning of the fire basin. 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 suspension 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.

[0072] 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.

[0073] 10. This invention can prevent welding slag accumulation: If welding slag is not properly handled, 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.

[0074] 11. This invention can adapt to different welding scenarios. Through the installation of pulleys, the welding 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.

[0075] 12. In this invention, before welding the reinforcing bars, the clamps are used to clamp the flanges at both ends of the small box girder, and a 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.

[0076] 13. This invention features a clamp for holding the steel wire rope of the fire-receiving basin, preventing slippage or loosening. The clamp firmly holds the 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.

[0077] 14. Fixtures improve safety. The fixing function of the fixtures prevents the fire-receiving basin from accidentally falling during operation, avoiding potential dangers to workers or equipment and improving overall operational safety. By fixing the wire rope with the fixtures, operators can easily control the height, angle, and direction of the fire-receiving basin as needed, making it better suited for welding operations. This avoids the trouble of frequent repositioning due to loosening or instability, thus saving time and effort and improving work efficiency. The stability of the fixtures allows welders to spend less time adjusting the position of the fire-receiving basin, thus focusing more on the welding work itself.

[0078] 15. Because the upper opening of the fire basin of the present invention 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 internal hollow 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.

[0079] 16. This invention effectively guides welding slag and sparks by setting an inclined guide plate inside the fire-receiving basin, enabling these welding slag and sparks to be concentrated in a safe area, reducing the probability of accidents; it can more effectively guide welding slag and sparks to designated locations, preventing them from scattering and splashing, reducing pollution to the working environment and potential fire risks.

[0080] 17. The guide plate of the present invention effectively diverts welding slag and sparks, preventing them from directly contacting other components in the fire basin, reducing the risk of equipment damage due to welding slag accumulation or excessive temperature, thereby extending the service life of the fire basin and other related equipment. Moreover, after the welding slag and sparks are effectively guided, the welding area is cleaner, which is conducive to maintaining a good working environment for operators, avoiding the impact of welding quality due to welding slag accumulation, and improving work efficiency. At the same time, the welding slag and sparks are concentrated in the area after being diverted by the guide plate, making cleaning more convenient, enabling quick cleaning of welding slag, and maintaining the cleanliness and efficient operation of the work area.

[0081] 18. The opening and closing door design of this invention allows the fire basin to be easily opened and closed, facilitating the cleaning of welding slag, sparks, and other residues. Operators can easily clean the inside of the fire basin, ensuring a clean welding environment and welding quality;

[0082] 19. The exterior of the present invention is coated with anti-rust paint and waterproof layer, which can prevent rusting and extend the service life of the entire fire basin. It is environmentally friendly 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 and underground construction environments. It can effectively play a safety reminder role, improve visibility, make it easy for people to identify, and increase safety in construction and life.

[0083] 20. This invention, by incorporating a protective guide component, can prevent injury from flying debris: During welding, sparks, slag, and other materials may fly out. The lifting protective guide component can effectively block the flying slag, reducing the risk of injury to operators; furthermore, the protective guide component can prevent the leakage of high-temperature gases and flames from the fire pit, reducing safety hazards caused by fire, especially in high-temperature and high-risk working environments.

[0084] 21. The fire basin (1) of the present invention is also provided with a traveling wheel (15) below, so that the fire basin can be easily moved between different positions, avoiding the problem that the fire basin is heavy and inconvenient to move. It is flexible and convenient to use, and minimizes the labor intensity of the operator.

[0085] 22. Since the suspension rope (4) used in this invention is made of fire-resistant and wear-resistant material, 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;

[0086] 23. The suspension rope of this invention is made of fire-resistant and wear-resistant material, which can extend its 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 suspension rope and reduce the need for frequent replacement of the suspension rope. The fire-resistant suspension rope can not only resist high temperature, but also often 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 suspension rope being damaged by high temperature. Attached Figure Description

[0139] Limiting connecting plate 511 is symmetrically connected to the outer side of the connecting plate below pulley connecting seat 21;

[0140] The limiting connecting seat 512 has one end rotatably connected between two limiting connecting plates 511 via a rotating shaft.

[0144] One end of the traction rope 53 is connected to the connecting ring in the middle of the connecting rod 52;

[0145] 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.

[0146] Furthermore, the pulley device 2 includes:

[0148] Pulley 22 is rotatably connected to the upper inner part of pulley connecting seat 21 via a connecting shaft; wherein,

[0149] The pulley connecting seat 21 includes a "[" shaped connecting plate and "∧" shaped side plates symmetrically connected to both ends of the connecting plate;

[0150] The pulley 22 has an inwardly recessed rope groove circumferentially arranged in the middle.

[0151] In this invention, pulley 22 is a finished pulley with a diameter of 80mm and a thickness of 23mm. Pulley 22 is welded to the four corners of the opening of the fire basin 1 via 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.

[0152] Furthermore, such as Figure 17 and Figure 18 As shown, the clamp 3 includes:

[0153] Adjusting rod 31;

[0154] Upper clamping plate 32 is sleeved above adjusting rod 31;

[0155] The lower clamping plate 33 is sleeved below the adjusting rod 31;

[0156] 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.

[0157] Specifically, such as Figure 17 and Figure 18 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;

[0158] 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;

[0159] The lower clamping plate 33 and the upper clamping plate 32 have the same shape, structure and size;

[0160] 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.

[0161] In this invention, 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 wet joint 6 of the T-beam. A hanging rope connection hole is provided at the lower end of the adjusting rod 31.

[0162] Before using the above-mentioned multifunctional bridge wet joint welding fire basin, the already manufactured fire basin of this design structure needs to be taken to the construction site for corresponding installation as a backup.

[0163] 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.

[0164] 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 and install the fire basin 1. One operator holds the fire basin 1 securely with the hoisting rope, while another operator... The operator then symmetrically passes 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 of the present invention is completed and it can be used after the installation is completed.

[0165] Before using this invention, 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 measure 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 process, 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.

[0166] In use, the operator only needs to use the pre-prepared welding equipment 9 to weld the reinforcing bars 7 of the wet joint of the T-beam. During the welding of the reinforcing bars 7 of the wet joint of the T-beam, when it is necessary to move the fire-receiving pan 1, the operator only needs to pull the traction rope 53, the limit wheel 513 disengages from the wire rope torsion spring 514, and moves the fire-receiving pan 1 forward; release the traction rope 53, the torsion spring 514 resets, and the limit wheel 513 pushes the wire rope upward to restrict the position of the fire-receiving pan 1, preventing it from slipping easily. Finally, after the position is fixed, the hook 54 is fastened to the existing steel reinforcement at the wet joint of the T-beam. The welding process is repeated on the ribs until all welding work is completed. Therefore, because this invention incorporates a limiting component, it can both limit the position of the welding basin and pull it. The limiting function effectively prevents the basin from shifting or tilting due to wind, vibration, or improper human operation during high-altitude work. The pulling 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 displacement and preventing fires or injuries from sparks or welding slag. It also reduces accident risks, addressing the issue of ineffective spark collection during basin displacement, which could lead to fires or injuries. The limiting component ensures precise basin positioning, thus reducing the risk of accidents. Furthermore, the pulling function allows for convenient adjustment of the basin's position, enabling operators to quickly move it to the desired location during high-altitude work. The manual operation steps of frequently adjusting the fire basin are reduced, saving time and improving work efficiency. The position of the fire basin can be easily adjusted 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. The limiting component can simultaneously drive the fire basin 1 to move back and forth, realizing the welding operation of the steel bars 7 of the wet joint of the T beam at different positions in a time-saving and labor-saving manner. During welding, the sparks and slag 91 fall freely downwards due to gravity and fall into the fire basin 1, realizing the centralized and unified collection of the sparks and slag 91.

[0167] 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 31. The section rod 31 is removed and separated. 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 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 the fire basin 1 is cleaned and repaired, the cleaned fire basin 1, together with the other components of the present invention, is transported to the designated tool storage warehouse for stacking and storage for the next cycle of use.

[0168] Throughout the entire implementation process described above, operators can prepare multiple fire-receiving basins of the present invention for installation and use, depending on the actual construction project requirements or the number of welders.

[0169] Example 2

[0170] Example 2 is the same as Example 1, except that, as Figures 1 to 4 As shown, it also includes a guide plate 12 disposed above the inner bottom plate of the fire-receiving basin 1. The guide plate 12 is inclined along the length of the inner bottom plate of the fire-receiving basin 1, and the guide plate 12 and the fire-receiving basin 1 are either a separate structure or an integrally formed structure. In the separate structure, one end of the guide plate 12 rests on the inner wall above one side of the wide side of the fire-receiving basin 1, and the other end of the guide plate 12 rests on the inner wall at the bottom of the other side of the wide side of the fire-receiving basin 1.

[0171] The integrated structure is that the guide plate 12 and the inner walls of the fire basin 1 are welded together as a whole.

[0172] In this invention, the guide plate 12 is a wedge-shaped plate, and the guide plate 12 is inclined downward from the limiting component 5 end to the opening and closing door 13 end.

[0173] When the above structure is in use, the welding slag 91 falls freely downwards due to gravity and into the fire-receiving basin 1. Because the fire-receiving basin 1 is equipped with an inclined guide plate 12, the welding slag and sparks can be effectively guided and concentrated in a safe area, reducing the probability of accidents. It can also more effectively guide the welding slag and sparks to a designated location, preventing them from scattering and reducing pollution to the working environment and potential fire risks.

[0174] Other specific uses are the same as in Examples 1 and 2, and will not be repeated here.

[0175] Example 3

[0176] This embodiment 3 is the same as embodiments 1 and 2, except that it also includes an opening and closing door 13, which is installed on the fire-receiving basin 1 near the lower end of the guide plate 12; the opening and closing door 13 includes:

[0177] Connecting shaft 131 is connected to both sides of one end of the fire basin 1 and is used to install door 132;

[0178] Door body 132 is rotatably mounted on connecting shaft 131;

[0179] The limiting component 133 consists of two limiting pins symmetrically arranged on the side plate of the fire basin 1 and two limiting brackets symmetrically arranged on the door body 132. The limiting pins are rotated and engaged on the limiting brackets to lock and fix the door body 132. Door guide openings are also provided at both ends of the upper part of the door body 132.

[0180] A push-pull handle 134 is attached to the outer wall of the door 132 to facilitate opening the door 132.

[0181] In this embodiment 3, after welding is completed, the operator can quickly empty the spark slag 91 in the receiving basin 1 by opening and closing the door 13. This facilitates the cleaning of slag, sparks, and other residues, ensuring a clean welding environment and high welding quality. The slag 91 can be centrally and uniformly poured out. After pouring, the operator simply closes the door 13 and locks the door 132 using the limiting component 133. This design facilitates the cleaning of slag, sparks, and other residues, ensuring a clean welding environment and high welding quality. It also allows for the centralized collection of spark slag 91.

[0182] Finally, the cleaned fire basin 1, along with the other components of the present invention, is transported to the designated tool storage warehouse for stacking and storage, in preparation for the next cycle of use.

[0183] Example 4

[0184] This embodiment 4 is the same as the other embodiments, except that, as Figures 19 to 24 As shown, it also includes a protective guide assembly 14 disposed on the fire-receiving basin 1, the protective guide assembly 14 comprising:

[0185] Guide telescopic component 141 is symmetrically connected to the three side panels and the door body 132 respectively;

[0186] The first protective guide plate 142 is respectively fitted inside the wing plate above the three side plates, and the first protective guide plate 142 and the corresponding guide telescopic member 141 below are detachably installed together, and the first protective guide plate 142 and the guide telescopic member 141 are telescopically coupled.

[0187] The second protective guide plate 143 is located inside the door body 132, and the two sides of the second protective guide plate 143 are detachably installed together with the corresponding guide telescopic component 141 below through the door body guide opening via connecting blocks, and the second protective guide plate 143 and the guide telescopic component 141 are in telescopic cooperation.

[0188] Limiting and tightening parts 144 are threadedly connected to the middle of the wing plates of the three side plates and the middle of the upper part of the door body 132 respectively;

[0189] The limiting and tightening member 144 is used to limit the extension of each of the first protective guide plates 142 and the second protective guide plates 143, preventing them from falling downwards.

[0190] In this invention, the top center of the first protective guide plate 142 and the second protective guide plate 143 is also connected to a C-shaped handle; the upper center of the first protective guide plate 142 and the second protective guide plate 143 is also provided with a tightening and limiting hole.

[0191] In this embodiment 4, the first protective guide plate 142 and the second protective guide plate 143 are located on the outside of the pulley device 2.

[0192] In use, this invention, by incorporating a protective guide component, can prevent injury from flying debris: During welding, sparks, slag, and other substances may fly out. The lifting protective guide component can effectively block the flying slag, reducing the risk of injury to operators; furthermore, the protective guide component can prevent the leakage of high-temperature gases and flames from the fire pit, reducing safety hazards caused by fire, especially in high-temperature and high-risk working environments.

[0193] Other specific installation and usage are the same as in Examples 1 to 4, and will not be repeated here.

[0194] Example 5

[0195] This embodiment 5 is the same as the other embodiments, except that, as Figure 25 and Figure 26 As shown, the first protective guide plate 142 and the second protective guide plate 143 are located inside the pulley device 2, or the first protective guide plate 142 and the second protective guide plate 143 are flush with the top side wall of the fire receiving basin. This ensures that during welding operations, the sparks and welding slag 91 that splash down from all sides will first pass through the first protective guide plate 142 and the second protective guide plate and finally enter the fire receiving basin 1 of the present invention. This prevents the possibility of the sparks and welding slag 91 splashing out from all sides of the fire receiving basin 1, further solving the risk that the sparks and welding slag 91 may be exposed on all sides during the falling process. This further achieves safety and reliability, improves the practicality and safety of the fire receiving basin, and meets the building standards requirements for civilized and safe construction.

[0196] Example 6

[0197] This embodiment 6 is the same as other embodiments, except that the fire basin 1 is 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.

[0198] In this invention, the fire basin 1 is made by cutting and welding a 2mm thin steel plate. The upper opening is 600*800mm, the lower basin bottom is 450x550mm, and the height is 300mm. The fire basin 1 has an overall structure with an open upper end 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.

[0199] When the above-mentioned design structure is in use, the larger opening at the top of the fire basin facilitates the placement or reception of fire sources, while the smaller opening at the bottom helps to concentrate the flames or heat, improving efficiency. The hollow internal structure can effectively accommodate combustibles or other heat sources, ensuring concentrated and even heat distribution. This design not only enhances the stability of the structure but also improves safety and ease of operation.

[0200] Other specific installation and usage details are the same as in other embodiments, and will not be repeated here.

[0201] Example 7

[0202] This embodiment 7 is the same as other embodiments, except that the two ends of the suspension rope 4 are fixed with locking clips 8 after passing through the suspension rope connection holes of the adjusting rod 31 on the same side.

[0203] The aforementioned design structure, when in use, features clamps to hold the steel wire rope of the fire-receiving basin, preventing slippage or loosening. These clamps securely hold the wire rope, preventing the basin from slipping or loosening due to vibration or changes in tension during welding. This ensures the fire-receiving basin remains in the correct position, effectively catching welding slag and sparks. The clamps also enhance safety, preventing the basin from accidentally falling during operation and avoiding potential hazards to workers or equipment, thus improving overall operational safety. By securing the wire rope with the clamps, operators can easily control the height, angle, and direction of the fire-receiving basin as needed, better facilitating the welding operation. This avoids the hassle of frequent repositioning due to loosening or instability, saving time and effort and improving work efficiency. The stability of the clamps allows welders to spend less time adjusting the position of the fire-receiving basin, allowing them to focus more on the welding work itself.

[0204] Example 8

[0205] This embodiment 8 is the same as other embodiments, except that, on any two opposite sides of the upper opening of the fire basin 1, there are also two symmetrically connected lifting rings 11, which are used to facilitate the installation and removal of the fire basin 1.

[0206] The aforementioned design, with its symmetrically placed lifting rings at the top opening of the fire basin, facilitates easy lifting, handling, and positioning. This ensures even force distribution during lifting, preventing tilting or swaying due to uneven lifting and thus improving stability. It also helps to precisely control the basin's suspension position, ensuring balance and stability during lifting, reducing human error, and preventing tilting or swaying, ensuring the basin remains in the intended 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.

[0207] Example 9

[0208] This embodiment 9 is the same as other embodiments, except that there are also walking wheels 15 connected to the four corners of the bottom of the fire basin 1.

[0209] In this invention, the hoisting 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.

[0210] When the above-mentioned design structure is in use, the fire-receiving basin 1 is also provided with a traveling wheel 15 below it, which allows the fire-receiving basin to be easily moved between different positions, avoiding the problem that the fire-receiving basin is heavy and inconvenient to move. It is flexible and convenient to use, and minimizes the labor intensity of the operator.

[0211] Example 10

[0212] This embodiment 10 is the same as other embodiments, except that the suspension rope 4 in this invention is a steel wire rope made using fire-resistant and wear-resistant methods.

[0213] In use, the suspension rope 4 is made of fire-resistant and wear-resistant material. Therefore, the rope 4, made of this material, has high temperature resistance and can withstand high temperatures for extended periods without damage. This ensures that even when the bottom of the fire pit is hot, the rope maintains its strength and stability, preventing breakage or deformation due to high temperatures, thus guaranteeing safety during use. Other specific installation and usage details are the same as in other embodiments and will not be repeated here.

[0214] Finally, it should be noted that the specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art.
