Description

Technical Field

[0001] This utility model specifically relates to an automatic flip-plate protective device for fire and slag collection in a fire-receiving basin, belonging to the technical field of fire-receiving basins. Background Technology

[0002] During welding construction in high-rise buildings, welding sparks fall from a great height, and these high-temperature sparks can easily pose a danger to the surrounding area. Therefore, to prevent welding sparks from splashing and falling during high-altitude welding, a spark-catching device needs to be installed below the welding area. This spark-catching device can receive welding sparks during component welding, avoiding burns to personnel caused by overlapping work at different levels, and preventing fire risks caused by falling sparks and welding slag. However, existing spark-catching devices are inconvenient to move. To address this, Chinese Patent Publication No. CN210451478U discloses an automatic flip-plate protective spark and slag catching device for a spark-catching basin. It includes a spark and slag catching device body and a protective flip plate set at the upper opening of the spark and slag catching device body. This structure is simple to install and disassemble, and can be reused multiple times. When in use, the protective flip plate at the upper perimeter will automatically rise to provide protection and prevent sparks or welding slag from falling out of the spark-catching basin. However, this slag catching device has poor adaptability to building welding positions and requires hoisting equipment for assistance, making operation relatively cumbersome. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes an automatic flip-plate protective device for receiving fire and slag in a fire basin. It employs a hanging and supporting method, making it adaptable to welding positions in various buildings, and is simple and convenient to operate.

[0004] This utility model relates to an automatic flip-plate protective device for receiving fire and slag in a fire-receiving basin, comprising:

[0005] A fire-receiving basin, which is a rectangular rectangular structure; a slag discharge device is provided at the bottom of the fire-receiving basin.

[0006] An elastic swing arm, which is fixed to both ends of the inner side of the fire basin along its length;

[0007] A flap is provided on the top surface of an elastic swing arm. One end of the flap is integrally formed with a folding part, and the other end of the flap is integrally formed with an extension part. The bottom of the flap and the folding part are movably embedded into the inside of the fire basin. The bottom and top surfaces of the extension part are integrally formed with a lower inward folding part and an upper inward folding part, respectively.

[0008] The end receiving basin is slidably disposed between extensions, and the top and bottom surfaces of the end receiving basin respectively abut against the lower inner fold and the upper inner fold; the end receiving basin near the fire receiving basin has a hollow structure, and an open slot is provided at the hollow end of the end receiving basin.

[0009] A support member is installed with an end receiving basin and is supported around the welded component.

[0010] In use, the flap is supported around the welded component by the support member, and the flap is pressed tightly against the bottom surface of the welded component. The flap is elastically supported by the elastic swing arm. When there is a crossover component at the welding position, the extension is snapped into the outside of the crossover component, so that the lower inner fold part elastically abuts against the crossover component. Then, the end receiving basin is snapped into the other side of the crossover component and installed with the lower inner fold part and the upper inner fold part. This allows the crossover component to be crossed, thereby receiving the sparks and slag around the welding position.

[0011] Furthermore, the support member is a support platform fixed to the bottom of the fire basin; the support platform includes a groove fixed to both sides of the bottom surface of the fire basin, a retaining seat is provided at the front end of the groove, and a right-angle retaining block is provided on the inner side of the retaining seat to engage with the column; one end of the right-angle retaining block near the retaining seat is fixed to a sliding shaft, the sliding shaft moves through the retaining seat, and a screw is screwed onto the retaining seat to tighten against the right-angle retaining block; in use, the groove is fixed to the fire basin, and the retaining seat is engaged with the vertical component. When the column is snapped together, the lower inner fold is pressed tightly against the column, achieving a tight grip between the lower inner fold and the column. Then, by rotating the screw, the screw pushes the right-angle locking block to press tightly against the column, and the corner of the right-angle locking block engages and limits the engagement with the outer edge of the column; thus achieving the snapping and tightening limit between the support platform and the column. Next, the end receiving basin is embedded into the lower inner fold and the upper inner fold, achieving a snap-fit ​​and covering of the outside of the column; thus, it can receive the spark welding slag at the welding position of the column and the horizontal component.

[0012] Furthermore, the elastic swing arm includes a seat plate fixed to the inner side of the fire basin, a swing rod hinged to the top of the seat plate, the bottom surface of the swing rod fixed to a hinge seat, a sliding rod hinged to the hinge seat, a force-bearing plate fixed to the sliding rod, a sliding disc provided below the force-bearing plate on the sliding rod, a spring body provided between the force-bearing plate and the sliding disc, a sliding groove provided on the seat plate, the sliding rod moving through the sliding groove and screwed with a limit nut; the sliding disc is pressed against the seat plate, and a limit bolt is screwed to the side of the sliding groove; the flip plate is installed with the swing rod. When the elastic swing arm is in use, when the flap is under force, the flap pushes the slide rod to slide along the sliding groove. At this time, due to the limiting of the sliding plate and the seat plate, the spring body between the sliding plate and the force plate is compressed, thus enabling the flap to be elastically tightened. When it is necessary to flip the flap outward to adapt to the corner position, the limiting bolt is screwed outward to disengage the slide rod from the sliding groove. At this time, the flap can be flipped freely, and due to the action of the limiting nut, the sliding plate and the spring body can be limited to prevent the sliding plate and the spring body from slipping.

[0013] Furthermore, a slide block is fixed to the back of the flip plate, and a long slide rail is provided on the swing rod. The slide block is movably engaged with the swing rod, and a sliding bolt is provided on the slide block. The sliding bolt is slidably installed in the long slide rail. During installation, the flip plate is slidably installed with the swing rod through the slide block, and the slide block and the long slide rail are slidably engaged through the sliding bolt.

[0014] Furthermore, the slag discharger is either a pull-out plate slidably disposed at the bottom of the fire-receiving basin, or a rotating flapper rolling at the bottom of the fire-receiving basin. One end of the rotating flapper extends movably beyond the fire-receiving basin and is fixed with a rotating crank. A locking bolt is rotatably disposed on the rotating crank, and the locking bolt is screwed into and limited by the fire-receiving basin. When the pull-out plate discharges slag, it can be pulled outward to discharge the cooled spark welding slag collected in the fire-receiving basin. After discharge, the pull-out plate is reset to receive welding slag. When the rotating flapper discharges slag, the locking bolt is rotated outward to disengage from the fire-receiving basin, and then the rotating crank is rotated to rotate the rotating flapper 90°. This discharges the cooled welding slag. After slag discharge, the rotating flapper is reset and locked by the locking bolt.

[0015] Furthermore, the bottom surface of the end receiving basin is provided with an arc-shaped deformation plate, the bottom of which is pressed against the top surface of the lower inner fold. The arc-shaped deformation plate can be deformed under force, thereby pressing the top surface of the end receiving basin tightly against the upper inner fold.

[0016] Furthermore, the support member is a hook hinged to both sides inside the fire basin. Before welding each horizontal steel component, the fire basin is placed on the bottom surface of the steel component and hooked to the steel component. During hooking, the flip plate is elastically tensioned to the bottom surface of the steel component to achieve stable hooking between the fire basin and the steel component. After welding is completed, the top flip plate is lifted to disengage the hook from the steel component.

[0017] Compared with the prior art, the automatic flip-plate protective fire and slag receiving device of this utility model uses hooks to hang the fire receiving basin, realizing horizontal welding of buildings. The support platform can support the fire receiving basin, realizing welding at the intersection of horizontal and vertical directions. It can adapt to the welding positions of various buildings, and is simple and convenient to operate, realizing the reception of spark welding slag. Attached Figure Description

[0025] Example 1:

[0026] like Figures 1 to 6 The automatic flip-plate protective device for receiving fire and slag in the fire-receiving basin shown includes...

[0027] Fire basin 1, which is a rectangular elongated structure; a slag remover is provided at the bottom of the fire basin 1.

[0028] Elastic swing arm 2, the elastic swing arm 2 is fixed to the inner two ends of the fire basin 1 along its length;

[0029] Flip plate 3 is disposed on the top surface of elastic swing arm 2. One end of flip plate 3 is integrally formed with folding part 4, and the other end of flip plate 3 is integrally formed with extension part 5. The bottom of flip plate 3 and folding part 4 are movably embedded into the inside of fire basin 1. The bottom surface and top surface of extension part 5 are integrally formed with lower inward folding part 6 and upper inward folding part 7, respectively.

[0030] The end receiving basin 8 is slidably disposed between the extension portions 5, and the top and bottom surfaces of the end receiving basin 8 respectively abut against the lower inner fold portion 6 and the upper inner fold portion 7; the end receiving basin 8 is hollow on the side near the fire receiving basin 1, and an open slot is provided in the hollow part of the end receiving basin 8; the open slot is the part that is recessed to the other side of the fire receiving basin 1.

[0031] A support member is installed with an end receiving basin 8 and is supported around the welded component.

[0032] In use, the flap 3 is supported around the welding component by the support member, and the flap 3 is pressed against the bottom surface of the welding component. The flap 3 is elastically supported by the elastic swing arm 2. When there is a crossover component at the welding position, the extension 5 is snapped into the outside of the crossover component, so that the lower inner fold 6 elastically abuts against the crossover component. Then, the end receiving basin 8 is snapped into the other side of the crossover component and installed with the lower inner fold 6 and the upper inner fold 7. This allows the crossover component to be crossed, thereby receiving the spark welding slag around the welding position.

[0033] The support is a support platform fixed to the bottom of the fire basin 1; the support platform includes a groove 9 fixed to both sides of the bottom surface of the fire basin 1, a retaining seat 10 is provided at the front end of the groove 9, and a right-angle retaining block 11 that engages with the column is provided on the inner side of the retaining seat 10; one end of the right-angle retaining block 11 near the retaining seat 10 is fixed to a sliding shaft, the sliding shaft moves through the retaining seat 10, and a screw 12 that is screwed onto the retaining seat 10 and tightens against the right-angle retaining block 11; in use, the groove 9 is fixed to the fire basin 1, and the retaining seat 10 is engaged with the column. When the support column of the component is engaged, the lower inner fold 6 is pressed against the column, thus achieving a tight grip between the lower inner fold 6 and the column. Then, by rotating the screw 12, the screw 12 pushes the right-angle locking block 11 to press against the column, and the corner of the right-angle locking block 11 engages and limits the engagement with the outer edge of the column. This achieves the engagement and tightening limit between the support platform and the column. Next, the end receiving basin 8 is embedded into the lower inner fold 6 and the upper inner fold 7 to achieve a locking and covering of the outside of the column, thereby receiving the spark welding slag at the welding position of the column and the transverse component.

[0034] The elastic swing arm 2 includes a seat plate 13 fixed to the inner side of the fire basin 1. A swing rod 14 is hinged to the top of the seat plate 13. The bottom surface of the swing rod 14 is fixed to a hinge seat 15. A slide rod 16 is hinged to the hinge seat 15. A force-bearing plate 17 is fixed to the slide rod 16. A sliding plate 18 is provided below the force-bearing plate 17 on the slide rod 16. A spring body 19 is provided between the force-bearing plate 17 and the sliding plate 18. A sliding groove 20 is provided on the seat plate 13. The slide rod 16 moves through the sliding groove 20 and is screwed with a limit nut 21. The sliding plate 18 is pressed against the seat plate 13. A limit bolt 22 is screwed to the side of the sliding groove 20. The flip plate 3 is installed with the swing rod 14. When the elastic swing arm 2 is in use, when the flap 3 is under force, the flap 3 pushes the slide rod 16 to slide along the sliding groove 20. At this time, due to the limiting of the sliding plate 18 and the seat plate 13, the spring body 19 between the sliding plate 18 and the force plate 17 is compressed; thus, the flap 3 can be elastically tightened. When it is necessary to flip the flap 3 outward to adapt to the corner position, the limiting bolt 22 is rotated outward to disengage the slide rod 16 from the sliding groove 20. At this time, the flap 3 can be flipped freely, and due to the action of the limiting nut 21, the sliding plate 18 and the spring body 19 can be limited to prevent the sliding plate 18 and the spring body 19 from slipping.

[0035] The flip plate 3 has a slide block fixed on its back. The swing rod 14 has a long slide rail 23. The slide block 24 is movably engaged with the swing rod 14. The slide block 24 is provided with a sliding bolt 25. The sliding bolt 25 is slidably installed in the long slide rail 23. During installation, the flip plate 3 is slidably installed with the swing rod 14 through the slide block 24, and the slide block 24 is slidably engaged with the long slide rail 23 through the sliding bolt 25.

[0036] The slag discharge device is either a pull-out plate slidably mounted on the bottom of the fire-receiving basin 1, or a rotating flap 3 rolled on the bottom of the fire-receiving basin 1. One end of the rotating flap 3 extends movably out of the fire-receiving basin 1 and is fixed with a rotating crank 26. A locking bolt 27 is rotatably mounted on the rotating crank 26, and the locking bolt 27 is screwed into and limited by the fire-receiving basin 1. When the pull-out plate discharges slag, it can be pulled outward to discharge the cooled spark welding slag collected in the fire-receiving basin 1. After discharge, the pull-out plate is reset to receive welding slag. When the rotating flap 3 discharges slag, the locking bolt 27 is rotated outward to disengage from the fire-receiving basin 1. Then, the rotating crank 26 is rotated to rotate the rotating flap 3 by 90°, thereby discharging the cooled welding slag. After discharge, the rotating flap 3 is reset and locked by the locking bolt 27.

[0037] The bottom surface of the end receiving basin 8 is provided with an arc-shaped deformation plate 28. The bottom of the arc-shaped deformation plate 28 is pressed against the top surface of the lower inner fold 6. The arc-shaped deformation plate 28 can be deformed under force, thereby pressing the top surface of the end receiving basin 8 tightly against the upper inner fold 7.

[0038] Example 2:

[0039] like Figure 6 As shown, the support is a hook 29 hinged to both sides inside the fire basin 1. Before welding each horizontal steel component, the fire basin 1 is placed on the bottom surface of the steel component and hooked to the steel component through the hook 29. When hooked, the flip plate 3 is elastically tensioned to the bottom surface of the steel component to achieve stable hooking of the fire basin 1 and the steel component. After the welding position is completed, the flip plate 3 is lifted to make the hook 29 detach from the steel component.
