Description

Technical Field

[0001] This application relates to the field of auxiliary equipment for building construction, and in particular to a fire basin for welding steel beams. Background Technology

[0002] In on-site welding construction of steel structures, welding is widely used to connect steel components. During welding, the melting of welding rods or wires produces a large amount of hot welding slag. When this slag falls from a height, it can easily burn workers below and may also ignite flammable materials such as safety nets and wooden formwork, posing a serious safety hazard.

[0003] Currently, fire-catching basins are commonly used as protective devices on construction sites to effectively collect and block falling welding slag. In practical applications, fire-catching basins are usually suspended directly below the welding point using wire binding to achieve temporary slag collection.

[0004] However, the wire binding method is prone to shaking when subjected to welding slag impact or wind load, increasing the risk of welding slag splashing out of the fire-collecting basin. Furthermore, when welding slag accumulates in the fire-collecting basin to a certain amount, it needs to be removed from the steel beam and transferred to a specific area for dumping and cleaning, causing welding operations to be interrupted and affecting overall construction efficiency. Summary of the Invention

[0005] To improve the connection stability of the fire-receiving basin and increase construction efficiency, this application provides a fire-receiving basin for welding steel beams.

[0006] This application provides a fire-receiving basin for welding steel beams, which adopts the following technical solution:

[0007] A fire-catching basin for welding steel beams includes a basin body, a support frame, a rotating base, a base plate connector, a fireproof bag, and a fixing component; The basin body includes a basin base and a bottom plate. The basin base is connected to the support frame, and the bottom plate is rotatably connected to the basin base. The rotating seat is rotatably connected to the support frame. The basin base is provided with a feed inlet, and the fireproof bag is connected to the feed inlet; the bottom plate connector is slidably disposed relative to the rotating seat; the fireproof bag is detachably connected to the basin base; The base plate connector is detachably connected to the base plate via the fastener; When the bottom plate connector drives the bottom plate to close the feed inlet, the bottom plate connector abuts against the rotating seat to restrict the bottom plate connector from sliding relative to the rotating seat towards the bottom plate, and is used to cooperate with the support frame and the basin seat to enclose the steel beam; With the bottom plate connector detached from the bottom plate, the bottom plate opens the feed port.

[0008] By adopting the above technical solution, the basin base is connected to the support frame, and the bottom plate connector is detachably connected to the bottom plate, so that the basin base, support frame and bottom plate connector can surround the steel beam on all four sides, thereby improving the stability of the connection between the fire basin and the steel beam.

[0009] Meanwhile, when the fire-collecting basin needs to be moved to the next welding station, after the base plate connector detaches from the base plate, the base plate opens the feed inlet under its own weight. This allows the welding slag collected on the base plate to enter the fireproof bag through the feed inlet, facilitating slag collection through the fireproof bag and reducing the possibility of welding operations being interrupted due to the disassembly of the entire fire-collecting basin from the steel beam and its relocation to a specific area for slag removal. Furthermore, during welding operations, the feed inlet of the base plate closes, and the welding slag generated from the steel beam welding falls into the basin base and accumulates on the base plate. This allows the welding slag to accumulate and dissipate heat on the base plate, reducing the possibility of high-temperature welding slag directly falling into the fireproof bag and damaging it.

[0010] Optionally, the fastener includes a hook and a buckle, the buckle being connected to the base plate, the hook being connected to the base plate connector, and the hook and the buckle being detachably connected.

[0011] By adopting the above technical solution, the buckle is connected to the base plate, the hook is connected to the base plate connector, and the hook and buckle are detachably engaged, which improves the efficiency of assembling and disassembling the base plate connector and the base plate.

[0012] Optionally, it also includes a fireproof bag connecting assembly; the fireproof bag connecting assembly includes a connecting seat and a locking member, and the opening of the fireproof bag is connected to the connecting seat; the basin base and the connecting seat are detachably connected by the locking member.

[0013] By adopting the above technical solution, the opening of the fireproof bag is connected to the connecting seat, and the connecting seat is then detachably connected to the basin base via a locking component, thereby allowing the fireproof bag to be detachably mounted on the basin base. When the fireproof bag is full of welding slag, the locking component enables quick assembly and disassembly of the fireproof bag, improving the efficiency of welding slag cleaning and the continuity of construction.

[0014] Optionally, the locking element includes a locking block, a limiting plate, an elastic element, and a trigger seat; The locking block is connected to the limiting plate, the limiting plate is slidably connected to the connecting seat, the elastic element is sleeved on the locking block, and the elastic element is disposed between the limiting plate and the connecting seat; the trigger seat is threadedly connected to the basin seat; the basin seat is provided with a connecting groove; The trigger seat abuts against and moves with the locking block, causing the locking block to insert into the connecting slot.

[0015] By adopting the above technical solution, the trigger seat and the basin seat are threadedly connected. When the trigger seat is rotated, it abuts against the locking block and pushes the locking block to move, causing the locking block to insert into the connecting groove on the basin seat, thereby locking the connecting seat to the basin seat. When the trigger seat is rotated out in the opposite direction, the elastic element drives the locking block to reset and disengage from the connecting groove, thus releasing the lock.

[0016] Optionally, the locking block is provided with a guide surface, and the trigger seat drives the locking block to move through the guide surface.

[0017] By adopting the above technical solution, when the trigger seat moves, it drives the locking block to move by pressing against the guide surface, thus converting the movement of the trigger seat into the movement of the locking block along the insertion direction.

[0018] Optionally, an operating lever is connected to the trigger seat.

[0019] By adopting the above technical solution, the operating lever makes it easier for construction personnel to rotate the trigger seat, thus improving the convenience of operation.

[0020] Optionally, the base plate connector includes a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate being rotatably connected, and the first connecting plate being detachably connected to the base plate; With the feed inlet closed by the base plate, the first connecting plate and the second connecting plate are misaligned, so that the first connecting plate is supported on the rotating seat by the second connecting plate.

[0021] By adopting the above technical solution, when the first connecting plate drives the bottom plate to close the feed port through the fixing component, the first connecting plate and the second connecting plate rotate relative to each other, so that the first connecting plate is supported on the rotating seat through the second connecting plate, thereby restricting the movement of the first connecting plate and reducing the possibility of the bottom plate opening when receiving welding slag.

[0022] Optionally, the base plate includes a first sealing plate and a second sealing plate; the first sealing plate and the second sealing plate are respectively rotatably connected to the basin seat; The bottom plate connector is detachably connected to the first sealing plate via the fixing member, and drives the first sealing plate to rotate, so that the first sealing plate drives the second sealing plate to close the feed port.

[0023] By adopting the above technical solution, the bottom plate connector drives the first sealing plate to rotate through the fixing component, and the first sealing plate then drives the second sealing plate to rotate, thereby enabling the first sealing plate and the second sealing plate to cooperate to close the feed port.

[0024] Optionally, the basin seat is further provided with a first positioning plate and a second positioning plate, wherein the first positioning plate is used to limit the rotation range of the first sealing plate and the second positioning plate is used to limit the rotation range of the second sealing plate.

[0025] By adopting the above technical solution, the first positioning plate restricts the rotation range of the first sealing plate, and the second positioning plate restricts the rotation range of the second sealing plate, so that welding slag can pass through the gap between the first sealing plate and the second sealing plate. At the same time, when the bottom plate connector drives the first sealing plate to rotate in the direction of closing the feed port, it can drive the second sealing plate to rotate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The basin base is connected to the support frame, and the base plate connector is detachably connected to the base plate. This allows the basin base, support frame, and base plate connector to enclose the steel beam on all four sides, thus improving the stability of the connection between the fire-receiving basin and the steel beam. Simultaneously, when the fire-receiving basin needs to be moved to the next welding station, the base plate connector detaches from the base plate, and the base plate opens its inlet under its own weight. This allows the welding slag collected on the base plate to enter the fireproof bag through the inlet, facilitating slag collection through the fireproof bag and reducing the possibility of welding operations being interrupted due to the need to disassemble the entire fire-receiving basin from the steel beam and move it to a specific area for slag removal. Furthermore, during welding operations, the base plate closes the inlet, and the welding slag generated from welding the steel beam falls into the basin base and accumulates on the base plate. This allows the welding slag to accumulate and cool on the base plate first, reducing the possibility of high-temperature welding slag directly falling into the fireproof bag and damaging it.

[0028] 2. By setting up a fireproof bag connecting assembly, the opening of the fireproof bag is connected to the connecting seat, and the connecting seat is then detachably connected to the basin base via a locking component, thereby allowing the fireproof bag to be detachably mounted on the basin base. When the fireproof bag is full of welding slag, the locking component enables quick disassembly and assembly of the fireproof bag, improving the efficiency of welding slag cleaning and the continuity of construction.

[0029] 3. By setting a first connecting plate and a second connecting plate, when the first connecting plate drives the base plate to close the feed port through the fixing component, the first connecting plate and the second connecting plate rotate relative to each other, so that the first connecting plate is supported on the rotating seat through the second connecting plate, thereby restricting the movement of the first connecting plate and reducing the possibility of the base plate opening when receiving welding slag.

[0038] The following combination Figures 1-7 This application will be described in further detail.

[0039] This application discloses a fire-receiving basin for welding steel beams, such as... Figure 1 and Figure 2 As shown, the fire-catching basin includes a basin body 1, a support frame 2, a rotating base 3, a base plate connector 4, a fireproof bag 5, a fixing component 6, and a fireproof bag connecting assembly 7. In this embodiment, the fireproof bag 5 is made of a high-temperature resistant material.

[0040] like Figure 2As shown, the basin body 1 includes a basin base 11 and a bottom plate 12. The basin base 11 is fixedly connected to the support frame 2. The support frame 2 is generally L-shaped and is used to support the basin body 1 on the steel beam 9. It cooperates with the basin base 11 and the bottom plate connector 4 to enclose the steel beam 9, so that the steel beam 9 passes through the structure enclosed by the support frame 2, the basin base 11, and the bottom plate connector 4 and is located above the basin base 11. The basin base 11 is used to catch the welding slag that falls during the welding of the steel beam 9. A feed inlet 111 is provided inside the basin base 11. The bottom plate 12 is rotatably connected to the basin base 11 and is used to close or open the feed inlet 111.

[0041] like Figure 1 and Figure 3 As shown, the rotating seat 3 is rotatably connected to the support frame 2. The base plate connector 4 includes a first connecting plate 41 and a second connecting plate 42, which are rotatably connected. The rotating seat 3 has a movable groove 31, through which the first connecting plate 41 passes, allowing it to slide relative to the rotating seat 3 along the movable groove 31.

[0042] like Figure 4 As shown, the base plate 12 includes a first sealing plate 121 and a second sealing plate 122, which are rotatably connected to the basin seat 11. A first positioning plate 113 and a second positioning plate 114 are also fixed on the basin seat 11. The first positioning plate 113 limits the rotation range of the first sealing plate 121, and the second positioning plate 114 limits the rotation range of the second sealing plate 122.

[0043] Furthermore, when the first sealing plate 121 and the second sealing plate 122 rotate under their own weight, the feed inlet 111 is opened. When the first sealing plate 121 rotates to abut against the first positioning plate 113, and the second sealing plate 122 rotates to abut against the second positioning plate 114, the end of the first sealing plate 121 away from the first positioning plate 113 is lower than the end of the second sealing plate 122 away from the second positioning plate 114. This allows the end of the first sealing plate 121 to abut against and lift the second sealing plate 122 as it rotates towards closing the feed inlet 111, causing the second sealing plate 122 to rotate synchronously. When the sides of the first sealing plate 121 and the second sealing plate 122 away from the feed inlet 111 are at the same height, the first sealing plate 121 and the second sealing plate 122 are joined together, thereby jointly sealing the feed inlet 111.

[0044] like Figure 1 and Figure 2 As shown, the fixing member 6 includes a hook 61 and a buckle 62. The buckle 62 is fixedly connected to the first sealing plate 121, and the hook 61 is fixedly connected to the first connecting plate 41. In this embodiment, the construction worker moves the base plate connecting member 4 so that the hook 61 hooks the buckle 62, thereby enabling the first sealing plate 121 to rotate through the base plate connecting member 4.

[0045] Furthermore, when the second connecting plate 42 is parallel to the first connecting plate 41, the second connecting plate 42 and the first connecting plate 41 can pass through the movable groove 31 together. After the bottom plate connector 4 drives the first sealing plate 121 and the second sealing plate 122 to splice and close the feed port 111, the second connecting plate 42 has passed through the rotating seat 3. At this time, rotating the second connecting plate 42 causes the second connecting plate 42 to rotate relative to the first connecting plate 41 and become misaligned with the first connecting plate 41. Due to the misalignment, the second connecting plate 42 cannot retract into the movable groove 31, thus abutting against and supporting itself on the rotating seat 3. Since the first connecting plate 41 is connected to the first sealing plate 121 via the hook 61 and the buckle 62, the first sealing plate 121 needs to move the first connecting plate 41 when it rotates in the direction of opening the feed port 111. The first connecting plate 41 is supported on the rotating seat 3 by the second connecting plate 42, thereby restricting the rotation of the first sealing plate 121 in the direction of opening the feed port 111 and reducing the possibility of the bottom plate 12 opening the feed port 111 when receiving welding slag.

[0046] like Figure 5 and Figure 6 As shown, the fireproof bag connecting assembly 7 includes a connecting seat 71 and a locking member 72. The opening of the fireproof bag 5 is fixedly connected to the connecting seat 71, and the basin seat 11 and the connecting seat 71 are detachably connected by the locking member 72.

[0047] Specifically, such as Figure 5 and Figure 7 As shown, the locking component 72 includes a locking block 721, a limiting plate 722, an elastic element 723, and a trigger seat 724. The locking block 721 is fixedly connected to the limiting plate 722, and the limiting plate 722 is slidably connected to the connecting seat 71. The elastic element 723 is sleeved on the locking block 721, and its two ends are fixedly connected to the limiting plate 722 and the connecting seat 71, respectively. Preferably, the elastic element 723 is a spring. The trigger seat 724 is threadedly connected to the basin seat 11, and the basin seat 11 is provided with a connecting groove 112. The locking block 721 is provided with a guide surface 7211, which is an inclined surface. An operating rod 8 is also fixedly connected to the trigger seat 724, which facilitates the rotation of the trigger seat 724 by the construction personnel, improving the convenience of operation.

[0048] In addition, such as Figure 4 As shown, a limiting step 711 is fixedly connected inside the connecting seat 71. When the connecting seat 71 and the basin seat 11 are installed, the limiting step 711 abuts against the end face of the basin seat 11, realizing the quick positioning of the connecting seat 71 and improving the convenience of installation.

[0049] After the connecting seat 71 is installed onto the basin seat 11, the fireproof bag 5 is connected to the feed inlet 111 of the basin seat 11 via the connecting seat 71, allowing the welding slag entering the basin seat 11 to fall into the fireproof bag 5 for collection. During the installation of the connecting seat 71 and the basin seat 11, after the limiting step 711 abuts against the end face of the basin seat 11, the construction personnel rotate the trigger seat 724 via the operating rod 8, causing the trigger seat 724 to move along the thread towards the fireproof bag 5. When the trigger seat 724 moves to abut against the guide surface 7211 and continues to move, the trigger seat 724 converts its own movement into the lateral movement of the locking block 721 through the inclined guide surface 7211, driving the locking block 721 to move towards the connecting groove 112 and insert into the connecting groove 112, thereby locking the connecting seat 71 onto the basin seat 11, realizing the connection between the fireproof bag 5 and the basin seat 11. When the fireproof bag 5 needs to be replaced, the construction worker rotates the trigger seat 724 in the opposite direction, causing the trigger seat 724 to move away from the fireproof bag 5. The elastic element 723 drives the locking block 721 to reset and disengage from the connecting groove 112, thereby releasing the lock between the connecting seat 71 and the basin seat 11, making it easier to replace the fireproof bag 5.

[0050] The implementation principle of a fire-receiving basin for welding steel beams in this application embodiment is as follows:

[0051] During installation, the steel beam 9 is inserted from the side where the bottom plate connector 4 is located and passed between the support frame 2 and the basin seat 11, so that the fire basin is placed on the steel beam 9 through the support frame 2.

[0052] Then, rotate the second connecting plate 42 to make it parallel to the first connecting plate 41. Next, the construction worker moves the base plate connector 4 so that the first connecting plate 41 and the second connecting plate 42 pass through the movable groove 31 and the hook 61 hooks the buckle 62.

[0053] After hook 61 hooks the buckle 62, the construction personnel move the base plate connector 4, so that the first connecting plate 41 drives the first sealing plate 121 to rotate in the direction of closing the feed inlet 111. The first sealing plate 121 abuts against and lifts the second sealing plate 122 so that they rotate synchronously to splice, thereby closing the feed inlet 111.

[0054] After the feed inlet 111 is closed, the second connecting plate 42 is rotated to make it misaligned with the first connecting plate 41, so that the first connecting plate 41 is supported on the rotating seat 3 through the second connecting plate 42, thereby locking the bottom plate 12 in the closed position. At this time, the support frame 2, the basin seat 11 and the bottom plate connecting piece 4 enclose the steel beam 9.

[0055] During welding operations, the first sealing plate 121 and the second sealing plate 122 close the feed inlet 111, and the welding slag produced by welding the steel beam 9 falls into the basin 11 and accumulates on the bottom plate 12. Because the welding slag first accumulates and cools down on the bottom plate 12, it only falls into the fireproof bag 5 after the feed inlet 111 is opened, thus reducing the possibility of high-temperature welding slag directly falling into the fireproof bag 5 and causing damage to the fireproof bag 5.

[0056] When it is necessary to change the welding station, the construction personnel rotate the second connecting plate 42 to restore it to parallel with the first connecting plate 41, so that the first connecting plate 41 resumes sliding along the movable groove 31; then adjust the position of the bottom plate connector 4 so that the hook 61 disengages from the buckle 62.

[0057] After hook 61 disengages from buckle 62, rotating seat 3, together with base plate connector 4, rotates around support frame 2, causing the enclosed structure formed by support frame 2, basin seat 11, and base plate connector 4 to open on the side where base plate connector 4 is located. Steel beam 9 can then be detached from this side, thereby moving the fire basin to the next welding station. At the same time, as hook 61 disengages from buckle 62, first sealing plate 121 and second sealing plate 122 rotate under their own weight and open feed port 111. Welding slag accumulated on base plate 12 falls into fireproof bag 5 through feed port 111 for collection. This allows for the cleaning of welding slag simply by replacing fireproof bag 5, reducing the possibility of welding operations being interrupted due to the overall disassembly and movement of the fire basin to a specific area for slag cleaning, and improving the continuity of welding operations.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
