[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a novel adjustable welding slag smoke and fire prevention device, comprising a collecting cover 2, a fixing ring 2 14 is fixedly connected to the bottom of the collecting cover 2, a fixing ring 1 13 is fixedly connected to the top of the collecting cover 2, three pull rods 3 are fixedly connected to the top of the fixing ring 13, the other end of the pull rod 3 is fixedly connected to a mounting block 12, the external rotation of the mounting block 12 is connected to a bidirectional threaded rod 9, the external thread of the bidirectional threaded rod 9 is connected to two limit blocks 10, the top of the limit block 10 is fixedly connected to a clamping plate 7, the outer side of the bidirectional threaded rod 9 is threadedly connected to a fixing block 8, and a collecting component is installed at the bottom of the fixing ring 2 14.
[0029] Specifically, first, the tops of the two clamps 7 are fitted with the bottom of the concrete beam. At this time, the bidirectional threaded rod 9 is rotated, and the two limit blocks 10 are driven to move toward each other under the action of the bidirectional threaded rod 9, thereby driving the two clamps 7 to approach each other, and the concrete beam is clamped by the two clamps 7. At the same time, the fixing block 8 is twisted so that the fixing block 8 is pressed against one of the limit blocks 10, so that the clamp 7 is further clamped and fixed, and the device is fixed to the bottom of the concrete beam, so that the ignition device can adapt to concrete beams of different sizes, which can simplify the design and manufacturing process of the entire system, thereby reducing the complexity of design and production, and reducing costs and time. The function of the fixing block 8 is to squeeze the limit block 10 so that the surface of the clamp 7 is further fitted with the bottom of the concrete beam, making the device more stable.
[0030] Reference Figure 1 , Figure 2 and Figure 4 The collecting assembly includes three connecting rings 11, the outside of the connecting ring 11 is fixedly connected to the bottom of the fixing ring 14, the outside of the connecting ring 11 is slidably connected to the supporting rod 5 through the hook 6, and the other end of the supporting rod 5 is slidably connected to the collecting bucket 1 through the hook 6, and three hanging holes 4 are opened on the outside of the collecting bucket 1.
[0031] Specifically, when the collection bucket 1 needs to be installed, first, one end of the support rod 5 is connected to the fixing ring 2 14 and the other end is connected to the collection bucket 1 through the hook 6. In this way, the collection bucket 1 is fixed to the bottom of the collection cover 2 and placed vertically with the fixing ring 2 14, so that the welding slag can completely slide into the interior of the collection bucket 1. A small amount of water is added to the interior of the collection bucket 1. When the construction workers are welding, the generated welding slag is gathered to the interior of the collection bucket 1 through the collection cover 2, and then the welding slag is extinguished by the water inside the collection bucket 1. When the collection bucket 1 needs to be disassembled, the above steps are repeated, and the hook 6 is detached from the hanging hole 4 on the outside of the collection bucket 1 to complete the disassembly of the collection bucket 1. By disassembling and installing the collection bucket 1, the operator can easily remove it and pour the welding slag into a designated disposal container or trash can without performing additional operations.
[0032] Reference Figure 1 and Figure 2 The diameter of the fixing ring 1 13 is larger than that of the fixing ring 2 14 , and the three pull rods 3 are evenly distributed in a triangular shape.
[0033] Specifically, the collecting cover 2 is made to be larger at the top and smaller at the bottom, so that 100% of the splashing welding slag and fireworks splash onto the surface of the unfolded collecting cover 2 and then slide into the interior of the collecting barrel 1 .
[0034] Reference Figure 1 and Figure 2 , the collecting cover 2 is made of fireproof cloth.
[0035] Specifically, a 1.5m×1.5m×0.5mm thick silicone rubber coated fireproof cloth is used, and the fireproof performance reaches the A-level fireproof requirements, and it has good flexibility and good water resistance and corrosion resistance.
[0036] Reference Figure 3 The support rod 5 is made of HRB400Φ6mm steel bar.
[0037] Specifically, HRB400Φ6mm steel bars have high rigidity, are not easy to deform, are easy to weld, have low weight, high tensile strength and good durability.
[0038] Reference Figure 1 The second fixing ring 14 and the collecting barrel 1 are vertically distributed to each other, and the diameter of the second fixing ring 14 is smaller than the diameter of the barrel mouth of the collecting barrel 1.
[0039] Specifically, the welding slag is made to slide into the collecting bucket 1 more easily, thereby achieving the effect of wetting the welding slag fireworks.
[0040] Reference Figure 1 and Figure 2 The collecting barrel 1 is made of metal, and both ends of the supporting rod 5 are fixedly connected to the hook 6.
[0041] Specifically, the collecting barrel 1 adopts a stainless steel metal barrel with an outer diameter of 20 cm and a height of 20 cm. The metal barrel has good fire resistance and does not deform. It is easy to obtain materials at the construction site, and waste materials can be recycled to save resources. The support rod 5 is connected to the fixing ring 2 14 and the collecting barrel 1 through the hook 6. Under the self-locking function of the hook 6, the collecting barrel 1 can be disassembled.
[0042] Working principle: When using this device, first fit the top of the two clamps 7 with the bottom of the concrete beam. At this time, rotate the bidirectional threaded rod 9 to make the two limit blocks 10 approach each other, thereby driving the two clamps 7 to approach each other, and clamping the concrete beam through the two clamps 7. At the same time, twist the fixing block 8 so that the fixing block 8 presses against one of the limit blocks 10, so that the clamps 7 are further clamped and fixed, and the device is fixed to the bottom of the concrete beam, so that the fire connection device can adapt to concrete beams of different sizes, thereby increasing the flexibility and versatility of the fire connection device.
[0043] In addition, when it is necessary to install the collection bucket 1, first, one end of the support rod 5 is connected to the fixing ring 2 14 and the other end is connected to the collection bucket 1 through the hook 6. In this way, the collection bucket 1 is fixed to the bottom of the collection cover 2 and placed vertically with the fixing ring 2 14. A small amount of water is added to the inside of the collection bucket 1. When the construction workers are welding, the generated welding slag is gathered to the inside of the collection bucket 1 through the collection cover 2, and then the welding slag is extinguished by the water inside the collection bucket 1. When it is necessary to disassemble the collection bucket 1, the above steps are repeated, the hook 6 is detached from the collection bucket 1, and the disassembly of the collection bucket 1 is completed. The operator does not have to interrupt work due to the accumulation of welding slag, thereby improving work efficiency and productivity. The collection bucket 1 can effectively store the welding slag and waste generated during the welding process to prevent the welding slag from being scattered into the work area or the surrounding environment.
[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
