Abstract
Description
Technical Field
[0001] The utility model relates to the field of building installation engineering, and particularly relates to a high-altitude welding reinforcement and fire isolation device for a belt corridor in a flammable and explosive area. Background Art
[0002] There are mechanical and electrical equipment, instruments and meters, storage tanks, pipelines, valves, and cables under the belt corridor in the flammable and explosive area. The media involved include coke oven gas, benzene volatile gas, steam, ammonia gas, etc., which is a key fire prevention area.
[0003] Due to the heavy corrosive environment where the corridor is located, most of the support components of the corridor are rusty, and some support components are severely rusty. To ensure the safe operation of the corridor, it is required to reinforce it. In addition, there is a large amount of dust during the operation of the corridor, so it is required to be enclosed. Therefore, the enclosure and reinforcement of the belt corridor in the flammable and explosive area are implemented together, and production is not stopped during the reinforcement and enclosure of the corridor.
[0004] The corridor is 16 to 23 meters high from the ground, and there are a large number of equipment, storage tanks, pipelines, valves, and cables below.

At the same time, there are sporadic gas leaks, benzene volatiles, and other released gases in the area, and there are risks such as high-altitude falls, object strikes, fires, explosions, burns, and poisoning. In particular, the risk of fire and explosion caused by gas leaks during hot work is extremely high.
[0005] When performing high-altitude welding operations in a flammable and explosive area, due to the high-temperature sparks, spatter, and harmful gases generated during the welding process, it is extremely easy to cause fire or explosion accidents, posing a serious threat to construction workers and on-site equipment. Traditional protective measures often have problems such as poor fixing effect and incomplete protection, and it is difficult to meet the safety requirements in complex environments.

[0037] The present utility model provides a high-altitude welding reinforcement fire isolation device for a belt corridor in an inflammable and explosive area, including:
[0038] The present utility model provides a high-altitude welding reinforcement fire isolation device for a belt corridor in an inflammable and explosive area. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , including:
[0039] A fire isolation device frame body assembly, the fire isolation device frame body assembly includes a column 1 and an upper crossbar 2, and the column 1 and the upper crossbar 2 are vertically welded to obtain an upper support;
[0040] An acrylic fiber fireproof cloth assembly, the acrylic fiber fireproof cloth assembly is fixed on the column 1;
[0041] A wire mesh assembly, the wire mesh assembly is arranged outside the acrylic fiber fireproof cloth assembly and fixed on the column 1;
[0042] A safety net, the safety net is arranged outside the wire mesh assembly and fixed on the column 1;
[0043] A gangplank, which is welded to the frame assembly of the fireproof isolation device to form a construction operation platform.
[0044] The utility model provides a fireproof isolation device for high-altitude welding reinforcement of a belt corridor in an inflammable and explosive area, which comprises a frame assembly of the fireproof isolation device, an acrylic fiber fireproof cloth assembly, a wire mesh assembly and a safety net.
[0045] The fireproof isolation device for high-altitude welding reinforcement of the belt corridor in the inflammable and explosive area according to the utility model isolates the hot work area from the equipment, storage tanks, pipelines, valves, cables and gas leakage areas below the corridor.
[0046] The frame assembly and the gangplank of the utility model construct a construction operation platform, solving the problems that scaffolding cannot be erected and the lifting vehicle cannot enter the construction site; the acrylic fiber fireproof cloth assembly plays the role of isolating the fire source, effectively preventing the welding sparks from splashing and the welding slag from falling, solving the fire and explosion risks brought by welding hot work; the wire mesh assembly and the safety net play a safety protection role for personnel falling and small tools falling, and also protect the acrylic fiber fireproof cloth from being smashed.
[0047] The utility model is light in weight, will not excessively increase the construction load, has sufficient strength and high safety, and has been proved in practice to fully meet the construction requirements for high-altitude welding reinforcement of the belt corridor in the inflammable and explosive area.
[0048] As Figure 5 shown, it shows the corridor closing device and the welding reinforcement area of the corridor, and Figure 6 compared with the device before reinforcement shown in Figure 5 , it is more secure. Since there are cables below the corridor and there is gas leakage in some equipment, storage tanks, pipelines and valves, fire and explosion prevention and control must be key points. To ensure construction safety, in
[0049] , the upper closed part of the corridor is a newly installed structure, and bolt and screw connections (welding is avoided) are planned to reduce the hot work risk (not considered as a key point). The lower support part of the corridor is a welded part, and a special fireproof isolation device is planned to be used for welding reinforcement to isolate the hot work area from the equipment, storage tanks, pipelines, valves, cables and gas leakage areas below the corridor, so as to solve the fire and explosion risks brought by welding hot work and the construction problems that scaffolding cannot be erected and the lifting vehicle cannot enter.
[0050] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4, the upper brackets are evenly arranged at intervals along the length direction of the aisle to be strengthened to obtain the overall upper brackets.
[0051] The utility model has strong practicability and is convenient for disassembly and erection. The welding reinforcement of the aisle is implemented in sections (each section is 10 meters long, along the length direction of the aisle). After the welding reinforcement of one section is completed, the fire isolation device is moved forward 10 meters, and then the welding reinforcement of another section is carried out.
[0052] The utility model can realize the high-altitude welding reinforcement operation of the belt aisle in the area where there are equipment, storage tanks, pipelines, valves, cables and flammable and explosive gas leakage below. It has high construction efficiency, low safety risk, less measure cost, and can be reused. It has novelty, practicability and originality, and has a good prospect of popularization and application.
[0053] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 , the frame assembly of the fire isolation device further includes a double-headed screw 3 and a lower cross bar 4;
[0054] Connect the overall upper brackets and the lower cross bar 4 through the double-headed screw 3.
[0055] Both ends of the double-headed bolt 3 have threads, and the middle is a screw rod that can be thick or thin, with high strength and stability. By rotating the cooperation of the threaded head and the nut, it can effectively prevent the loosening or falling off of the connecting parts, and can maintain the firmness of the connection even when subjected to a large external force.
[0056] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 , the frame assembly of the fire isolation device further includes a connecting piece 5 and a connecting plate 6;
[0057] Stack the connecting piece 5 and the connecting plate 6 vertically along the horizontal plane and weld them vertically to obtain the operation surface for welding reinforcement.
[0058] Vertical welding can ensure that the weld has higher resistance when subjected to forces in the vertical direction. This welding method makes the combination between the connecting piece 5 and the connecting plate 6 more compact, thereby improving the strength and stability of the overall structure. Vertical welding can reduce the stress concentration phenomenon at the weld and extend the service life of the structure. The operation surface after welding reinforcement is more stable, can withstand greater loads and impacts, and provides a safe working environment for workers. The stable structure reduces the accident risk caused by the loosening or failure of the structure and guarantees the safety of workers' lives.
[0059] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4, the operation surface of the welding reinforcement operation and the upper cross arm 2 are connected by bolts.
[0060] The bolt connection tightly connects the operation surface of the welding reinforcement operation and the upper cross arm together through the pre-tightening force, forming a stable structural system. This connection method can withstand large loads and impacts, ensuring the overall stability of the structure.
[0061] In some embodiments, both ends of the whole upper bracket extend beyond the aisle of the corridor by a predetermined distance. In one embodiment, this predetermined distance can be 65 mm.
[0062] Both ends of the whole upper bracket extending beyond the corridor aisle can more effectively disperse the loads borne by the structure. Enabling the bracket to bear more external pressure, improving the stability and safety of the overall structure. In areas with strong winds, reducing the direct impact of the wind on the corridor aisle and enhancing the wind resistance of the corridor. The extended parts at both ends of the bracket can serve as a wind pressure buffer zone, reducing the impact of wind pressure on the main structure of the corridor.
[0063] In some embodiments, the model of the double-headed screw 3 is M20×2100 mm.
[0064] In some embodiments, the material of the gangplank is hot-dip galvanized steel.
[0065] The hot-dip galvanized steel gangplank usually adopts a row of convex holes design, which not only reduces the self-weight of the gangplank, but also enhances the anti-slip performance, preventing workers from having accidents due to slipping during the operation. In addition, the row of convex holes design helps to prevent the gangplank from deforming, ensuring the stability of the structure.
[0066] In some embodiments, please refer to Figure 1 , Figure 7 and Figure 8 , the acrylic fiber fireproof cloth assembly, the wire mesh assembly, and the safety net are fixed on the column 1 by M16 bolts.
[0067] The M16 bolts have a high load-bearing capacity and tensile resistance, which can effectively ensure the firm connection between the fireproof cloth assembly, the wire mesh assembly, and the safety net and the column 1. This high-strength connection method makes the whole structure not easy to loosen or fall off when subjected to external forces, thus improving the stability and safety of the overall structure.
[0068] In some embodiments, the high-altitude welding reinforcement fireproof isolation device for the belt corridor in the inflammable and explosive area of the present utility model further includes a gas detection device arranged in the operation area for discharging harmful gases from the operation area.
[0069] The gas detection device can monitor the concentration of harmful gases in the operation area in real time, continuously monitor and discharge harmful gases, and can keep the air quality in the operation area at a good level, thus effectively avoiding the occurrence of safety accidents such as poisoning and asphyxiation.
