Description

Technical Field

[0001] The utility model relates to the technical field of welding construction safety, in particular to a welding spark overflow prevention device for a profiled sheet roof fixing bracket. Background Art

[0002] The profiled sheet roof is widely used in the roof structure system of industrial factories. The common materials of the profiled sheet are metal or fiberglass. The roof panel is fixed on the bottom fixing bracket by bolts, etc., and the fixing bracket is fixed on the roof purlin by welding. In a specific production process environment, a large amount of corrosive media is generated, which seriously affects the safety and service life of the metal profiled sheet roof of the industrial factory, resulting in rust perforation of the metal profiled sheet roof. Therefore, it is necessary to replace the metal profiled sheet roof and its supporting fixing brackets.

[0003] During the cutting of the original fixing bracket and the welding construction of the new fixing bracket, a large amount of flying sparks will be generated. During the construction process, it should be avoided that the sparks affect the equipment, flammable substances, personnel, etc. below the construction area and pose safety hazards. Traditional protective measures usually arrange fire watchers in the welding area and equip fire extinguishers. The flammable substances and equipment are covered with fireproof cloth above, or a fireproof cloth is stretched and arranged at a high altitude below the hot work area. This kind of protective measure is time-consuming, laborious, material-consuming and has low economic benefits. There is also a method of installing a fire receiving basin below the hot work point to collect the flying sparks generated during the construction process. The currently common fire receiving basins are mainly suspended type, and the fire receiving basin is suspended below the hot work point through hanging parts. The installation is relatively inconvenient, and there is a certain distance between the hot work point and the fire receiving basin, so there is a risk of spark overflow. For the welding construction of the profiled sheet roof fixing bracket on the purlin, there are many hot work points and the distribution range is wide, and it is necessary to frequently disassemble and move the fire receiving basin. Therefore, this suspended type fire receiving basin is not suitable for the welding construction of the profiled sheet roof fixing bracket. Summary of the Invention

[0014] Figure 4 Schematic diagram of this anti-overflow device being disassembled from the upper flange plate of the roof purlin

[0015] Figure 5 Schematic diagram of the application of this anti-overflow device Specific implementation method

[0016] For example Figure 1 and Figure 2 As shown in and , this profiled sheet roof fixing bracket welded with a spark anti-overflow device includes a left open fire receiving groove 1, a right open fire receiving groove 2, a clamping plate 3 and a baffle 4. The two sides of the left open fire receiving groove 1 and the right open fire receiving groove 2 are hinged through a pin shaft 11. The clamping plate 3 is respectively arranged along the length direction at the opening edges of the left open fire receiving groove 1 and the right open fire receiving groove 2. The baffle 4 is respectively provided with limiting long grooves 41 and 42 at the middle and one side. The two sides of the left open fire receiving groove 1 are respectively provided with limiting rods 12. The baffle 4 is respectively arranged on the two sides of the left open fire receiving groove 1 and the right open fire receiving groove 2. And the pin shaft 11 penetrates into the middle limiting long groove 41 of the baffle 4, and the limiting rod 12 penetrates into the one-side limiting long groove 42 of the baffle 4. Nuts are respectively screwed onto the pin shaft 11 and the limiting rod 12.

[0017] Preferably, the left open fire receiving groove 1 and the right open fire receiving groove 2 respectively include a bottom plate and side plates arranged on three sides of the bottom plate. The clamping plate 3 is arranged at the opening edge of the bottom plate.

[0018] Preferably, fire extinguishing blankets 5 are respectively arranged on the fire receiving surfaces of the bottom plates of the left open fire receiving groove 1 and the right open fire receiving groove 2. The fire extinguishing blankets are used to receive the sparks generated during the welding process, avoid multiple rebounds and splashes of the sparks, and ensure that the sparks fall into the left open fire receiving groove and the right open fire receiving groove.

[0019] Preferably, light lifting chains 6 are arranged at intervals on the opening and closing top edges of the left open fire receiving groove 1 and the right open fire receiving groove 2. The light lifting chains are used to operate the opening and closing of the left open fire receiving groove and the right open fire receiving groove. Lifting the light lifting chain makes the left open fire receiving groove and the right open fire receiving groove close, and putting down the light lifting chain makes the left open fire receiving groove and the right open fire receiving groove open.

[0020] Such as Figure 3 、 Figure 4 and Figure 5As shown in the figure, the left open fire receiving groove 1 and the right open fire receiving groove 2 achieve the adjustment of the opening size of the lower clamping plate 3 by rotating in two directions, counterclockwise and clockwise. The left open fire receiving groove 1 and the right open fire receiving groove 2 can be clamped on the upper flange plates of different types of roof purlins 7 through the clamping plate 3. During the welding operation, this anti-overflow device is placed at the hot work point where the welding support is required through the lightweight lifting chain 6. The clamping plate 3 of the left open fire receiving groove 1 is inserted into the bottom surface of one side of the upper flange plate of the roof purlin 7, and the lightweight lifting chain 6 is slowly lowered, so that the clamping plate 4 of the right open fire receiving groove 2 is inserted into the bottom surface of the other side of the upper flange plate of the roof purlin 7, thereby reliably fixing this anti-overflow device at the hot work point. The position of the baffle 4 is adjusted through the limit long groove of the baffle 4 to close both sides of the left open fire receiving groove 1 and the right open fire receiving groove 2, so that the hot work point is enclosed within the left open fire receiving groove 1, the right open fire receiving groove 2 and the baffle 4, which can block the risk of welding sparks overflowing to the greatest extent. After this anti-overflow device is set up, the fixed support 8 on the upper flange plate of the roof purlin 7 can be welded. The welding sparks converge within the left open fire receiving groove 1, the right open fire receiving groove 2 and the baffle 4, achieving the purpose of preventing the overflow of welding sparks. After the fixed support at this place is welded, the lightweight lifting chain 6 is lifted to disengage the clamping plates 4 of the left open fire receiving groove 1 and the right open fire receiving groove 2 from the upper flange plate of the roof purlin 7, and then this anti-overflow device can be moved to the next hot work point to continue the welding operation of the fixed support.

[0021] This anti-overflow device has a simple structure, is lightweight and portable, and is easy to operate. After this anti-overflow device is placed at the welding operation position of the fixed support, the surrounding of the welding point is completely in a closed state, which can effectively block the risk of spark overflow. By setting a sliding baffle and rotatable left and right open fire receiving grooves, this anti-overflow device can be applied to welding operations of different forms of fixed supports and different forms of roof purlins, with strong applicability. Applying this anti-overflow device can greatly reduce the safety hazards caused by the splashing of welding sparks, improve the construction efficiency of welding operations, and reduce the construction cost of replacing the roof profiled sheet.
