Description

TECHNICAL FIELD

[0001] The utility model relates to the bridge wet joint welding fire pan for highway, municipal project uses, concretely relates to an improved bridge wet joint welding fire pan, mainly is used to collect the welding slag or spark generated in the bridge wet joint welding process, guarantees the use fire safety in the welding process, belongs to the building construction safety protection technical field. BACKGROUND

[0002] It is known that in the building construction process, welding steel bar, welding steel beam, welding formwork, welding scaffold and T beam etc. construction need special welding, in the process of welding, there will be molten metal, welding medicine splashing out, forming welding spark, if the welding work is completed on the ground, these splashing sparks have no big influence, but with the building heightening, especially high-rise building, welding spark falls from high altitude, will produce some thorny problems, first, the range of spark scattering is wider when welding from high altitude, and the spark can be blown away from the work point by wind, increase the possibility of fire, second, the spark falls on the low layer worker or passerby, causes scald, fire and other serious consequences, leads to possible work injury, third, the spark falls on the building construction equipment or construction tool, can damage the equipment or construction tool, the maintenance and protection requirement of equipment itself is higher, without fire pan to collect spark, can cause the surface of equipment to be burned by spark, increase the equipment failure rate, influence work progress, fourth, the spark falls on the combustible material, can cause fire, the spark generated in the welding process can scatter and splash to the combustible material around, such as wood, paint, cloth etc., if there is no fire pan to collect spark, the spark can fall to the ground or nearby building, cause fire, fifth, pollute the environment: the spark and the metal particle generated in welding can pollute the environment, especially without fire pan to collect, the scattered metal particle can spread in the air, even cause certain pollution to the environment below, sixth, poor cleanness, if the spark and splash after welding are not collected in time, can influence the cleanness of work environment, lead to the equipment and work surface not neat, further influence the safety of operation, seventh, reduce work efficiency, in order to avoid the accident caused by spark scattering, the worker can need to stop frequently to check, even suspend operation, this can prolong the operation time, reduce work efficiency, eighth, because many fire pans are used in high altitude, therefore, when installing, because there is no corresponding structure specially used for hoisting, when installing or disassembling, all rely on the direct installation and disassembly of construction personnel, for the heavy fire pan, at least two operators need to cooperate to install or disassemble the fire pan when installing and disassembling, time-consuming and laborious, there is also safety risk, ninth, because the traditional fire pan is the structure that the top is open and the bottom is closed,

[0003] Although it can be used to receive the welding slag sparks falling during welding, since the corresponding structure for facilitating subsequent cleaning of the welding slag sparks or convenient collection is not arranged on the fire receiving basin, the subsequent fire receiving basin is time-consuming and laborious when dumping the welding slag sparks, and the fire receiving basin needs to be cleaned multiple times. In short, it is often very inconvenient.

[0004] In recent years, with the rapid development of highway construction, in order to reduce the waste of land, the ratio of highway bridges and tunnels is increasing, and T-shaped beam bridges account for a large part in bridge design. However, bridge engineering is located in a forest area, and welding operations are prone to welding slag falling and fire hazard; the past fire receiving basin is not easy to install, has low practicality, is resisted by workers, is inconvenient to move, and most workers will not use the fire receiving basin due to various reasons such as inconvenience to carry and use, and safety accidents often occur.

There are 380 welding lines for bridge deck wet joints, and as many as 75,000 welding joints, which pose a fire hazard. During the welding process of the wet joint, due to the construction requirements of spot welding first and full welding later, the traditional fire receiving basin is blocked by the wet joint steel bars and cannot be moved with the welding work, making it difficult to use. Therefore, a sliding type fire receiving basin with this structure is designed to achieve efficient protection of the fire receiving basin for welding ignition.

[0006] After searching, the Chinese utility model patent with patent publication number CN211162520U discloses a fire receiving hopper, which comprises a length-adjustable supporting rod, a pair of pulleys fixed to opposite ends of the supporting rod and capable of being braked, the length of the supporting rod being adjusted to adapt to the width of the steel profile to be welded so that the pulleys are arranged on the top surface of the steel profile to be welded, and a fire receiving basin formed with a receiving space, opposite sides of the fire receiving basin being connected with hanging rods, the pair of hanging rods being connected to opposite ends of the supporting rod correspondingly, and the fire receiving basin being hung on the bottom of the steel profile to be welded. Although the above-mentioned design structure of the fire receiving hopper can solve the technical problem that the distance between the fire receiving basin and the welding point is too large, and the sparks generated during welding are easy to splash out of the fire receiving basin after the welding position is moved, which poses a safety hazard, the above-mentioned fire receiving hopper still has the problems of complex structure, large occupied area, and the need for a large operation space to realize the structure, small range of fire receiving and slag receiving, inconvenient operation, and the need for at least two operators to cooperate to use, in short, it is often very inconvenient.

[0062] The working principle is that before use, the improved fire pan for bridge wet joint welding with the above-mentioned design structure needs to be taken to the construction site for corresponding installation as a backup after being manufactured.

[0063] Before installation, the operator only needs to place the manufactured sliding fire pan with the design structure at the designated construction position by using corresponding handling equipment or directly by manual carrying or lifting, and then install it.

[0064] During installation, the operator only needs to firstly install the four prepared clamps (3) in twosymmetrically on the two ends of the two adjacent T-beams, specifically, the upper clamping plate (32) and the lower clamping plate (33) are clamped and connected on the flange of the end of one box girder wing plate (6), after stable and reliable installation, the upper clamping plate (32) and the lower clamping plate (33) are locked and fixed by the adjusting locking piece (34), and the same installation method is used to complete the installation of the other three clamps (3); then, after the installation of the four clamps (3) is completed and stable and reliable, one of the operators uses the prepared rope or lifting rope to connect the fire pan (1) for lifting and installing the fire pan (1), after the fire pan (1) is stably lifted by one of the operators through the lifting rope, the other operator passes two ropes (4) in twosymmetrically through the four pulley devices (2) arranged at the upper end opening of the fire pan (1), in the installation process, it is necessary to ensure that the fire pan (1) is safely and stably installed on the two ropes (4), then the two ropes (4) with the fire pan (1) are connected on the same axis and installed on the corresponding two clamps (3) on both sides of the two ends of the box girder wing plate (6), and the fire pan (1) is just clamped and located in the end T-beam wet joint in the middle of the two box girder wing plates (6), after stable and reliable installation and adjustment of the tension of the two ropes, the ends of the two ropes (4) are fixed by the locking clamp (8), after stable and reliable fixation, the installation of the utility model is completed, and the utility model can be used after the installation is completed.

[0065] Before use, the operator needs to first look at the position of the fire pan (1), and needs to ensure that the fire pan (1) is located directly below the T-beam wet joint to be welded, which plays a protective role and can also realize concentrated collection of spark welding slag (91) without leakage, prevents the spark welding slag (91) from falling out of the fire pan (1), during the above installation and use process, the two ropes (4) are used as component structures for stable and reliable displacement or walking suspension of the fire pan (1), after stable and reliable installation of the above fire pan (1), the fire pan (1) can be used normally.

[0066] In use, the operator only needs to use the prepared welding equipment (9) to weld the T-beam wet joint welding reinforcement (7) that needs to be welded. During the welding of the T-beam wet joint welding reinforcement (7), the inner side wall of one side of the fire receiving basin (1) can be pushed and pulled forward by using the rod-shaped reinforcement on site or other on-site construction tools as needed according to the actual situation, so as to realize the forward and backward movement of the fire receiving basin (1) at the same time, realize the time-saving and labor-saving welding operation of the T-beam wet joint welding reinforcement (7) at different positions, and realize the time-saving and labor-saving welding operation of the T-beam wet joint welding reinforcement (7) at different positions. During welding, the sparks and welding slag (91) move downward as free falling bodies due to the action of gravity and fall into the fire receiving basin (1). Since the inclined guide plate (12) is arranged in the fire receiving basin (1), the sparks and welding slag (91) can be effectively guided and concentrated in a safe area, reducing the probability of accidents. The sparks and welding slag (91) can be more effectively guided to the designated position, avoiding their scattering and splashing, reducing pollution to the working environment and potential fire risk, and realizing centralized and unified collection of the sparks and welding slag (91).

[0067] Finally, as time goes on, when all the welding construction is completed, one of the operators again uses the prepared corresponding rope or lifting rope to pass through the lifting ring (11) arranged on the fire receiving basin (1), lifts the fire receiving basin (1), and then the other operator removes the four clamps (3) installed on the box girder wing plate (6) respectively. When the clamp (3) is removed, the operator needs to loosen the adjusting lock (34) on the adjusting rod (31) first, so that the upper clamp plate (32) and the lower clamp plate (33) are separated from the flange at the end of the box girder wing plate (6), and then the upper clamp plate (32) and the lower clamp plate (33) are taken out and separated from the adjusting rod (31). Then, the operator opens each lock (8) respectively, and then pulls out the two lifting ropes (4) from the two ends of the fire receiving basin (1) to separate them from the fire receiving basin (1). At the same time, the operator recycles and arranges the two lifting ropes (4), and at the same time, the fire receiving basin (1) is lifted to the designated position by the lifting rope, and then the sparks and welding slag (91) in the fire receiving basin (1) are poured out. When pouring the sparks and welding slag (91), the operator only needs to open the opening and closing door (13) arranged at one end of the fire receiving basin (1) to quickly pour out the sparks and welding slag (91) in the fire receiving basin (1), so as to facilitate the cleaning of the sparks, welding slag and other residues, and easily clean the inside of the fire receiving basin (1), ensuring the cleanliness of the welding environment and the welding quality. The sparks and welding slag (91) are concentrated and poured out uniformly. After pouring is completed, the operator only needs to close the opening and closing door (13) and lock the door body (132) by the first limiting component (133),

[0068] Finally, the cleaned fire pan (1) is transported to the designated tool storage warehouse together with other components of the utility model for stacking storage, ready for next cycle turnover.

[0072] 2. The utility model sets a limiting assembly on the fire pan, which can realize the limiting function of the fire pan and the traction function of the fire pan, the limiting function realizes the limiting of the fire pan, can effectively avoid the displacement or inclination of the fire pan in high-altitude operation due to wind force, vibration or improper human operation, and the traction function can conveniently adjust the position of the fire pan, the operator can quickly move the fire pan to the required position through the traction function, and the high-altitude welding operation is more safe, reliable and efficient;

[0073] 3. The utility model can not only improve the position stability of the fire pan, ensure the effective collection of sparks and welding slag, and thus improve the safety and efficiency of the welding operation, but also reduce equipment wear and tear, improve the cleanliness of the operation environment, and reduce the risk of manual operation;

[0074] 4. The limiting assembly of the utility model can ensure that the fire pan always remains at the predetermined position, reduce the safety hazards caused by the deviation of the fire pan, avoid the splashing of sparks or welding slag to cause fire or injury, and also reduce the risk of accidents, solve the problem that the welding sparks may not be effectively collected when the fire pan is displaced, and even cause fire or injury, and the limiting assembly can ensure the accuracy of the position of the fire pan, thereby reducing the risk of accidents;

[0075] 5. The limiting component of this utility model also has a traction function, which enables convenient adjustment of the position of the fire basin.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

Avoid the trouble of frequent repositioning due to loosening or instability, thereby saving time and effort and improving work efficiency. The stability of the clamp makes the welding worker can spend less time adjusting the position of the fire pan, so as to focus more on the welding work itself;

[0085] 15、Since the upper end opening of the utility model discloses the fire pan is larger, it is convenient to place or receive the fire source, and the lower end is smaller, which helps to concentrate the flame or heat and improve the use efficiency. The hollow structure can effectively accommodate the burning material or other heat source, ensure the heat concentration and uniform distribution, which not only enhances the stability of the structure, but also improves the safety and operation convenience;

[0086] 16、The utility model discloses through setting the inclined deflector in the fire pan, effectively guides the welding slag and spark, can make these welding slag and spark concentrate to the safe area, reduces the probability of the accident occurrence.

Operators can easily clean the inside of the fire basin, ensuring a clean welding environment and welding quality;

[0089] 19. 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 can have 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;

[0090] 20. 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.
