Abstract
Description
Technical Field
[0001] This application relates to the field of welding construction technology, and more specifically, to a steel structure welding slag collection device. Background Technology
[0002] With the gradual development and maturation of steel structure technology, steel structure bridges are increasingly being used in transportation bridge and road construction due to their significant advantages, and more and more steel structure bridges are being put into production. Welding is an indispensable process in steel structure production. However, during welding, spatter is generated, posing a safety hazard of burning other construction workers. Furthermore, the high-temperature spatter cools rapidly and adheres to the structural components after falling on them. Preventing the spatter from affecting construction safety is crucial, making the collection of spatter generated during steel structure welding particularly important. Utility Model Content
[0003] This application provides a steel structure welding slag collection device, which has a simple structure and can be quickly assembled with steel structure components to effectively collect welding slag generated during the welding process.
[0004] This application provides a steel structure welding slag collection device, which includes a collection tray and a first magnetic fixing member. The collection tray includes a base plate and multiple side plates. The multiple side plates are connected to at least two sides of the base plate, and at least one side of the base plate is not provided with a side plate to form an open side of the collection tray. The base plate has a notch on the open side for the collection tray to accommodate steel structure components. The first magnetic fixing member is provided at the bottom of the base plate and is located around the notch. The first magnetic fixing member is used to magnetically engage with the steel structure components to position the collection tray on the steel structure components.
[0005] In this design, the collection tray includes a base plate and side plates. The base plate has a notch, allowing the collection tray to be inserted into the steel structure component. A first magnetic fastener located around the notch on the base plate then magnetically connects and fixes the collection tray to the steel structure component. Since the steel structure component is made of iron, the magnetic force of the first magnetic fastener engages with the component, thus magnetically securing the collection tray to the steel structure. The collection tray is easy and quick to install and can be rapidly disassembled from the steel structure, improving welding efficiency. Furthermore, the side plates on the collection tray, connected to the base plate, effectively block welding slag spatter during welding, reducing the risk of burns to workers and enhancing safety. The spatter falls onto the base plate after being blocked by the side plates, completing the collection process. Workers do not need to collect the slag secondaryly, resulting in high construction efficiency.
[0006] In some embodiments, the first magnetic fastener is a permanent magnet, and there are multiple first magnetic fasteners, all of which are magnetically connected to the periphery of the steel structure component.
[0007] In the above technical solution, by using a permanent magnet as the first magnetic fixing component, compared with an electromagnet, the permanent magnet has a simpler structure and lower cost, and can better achieve magnetic connection with the steel structure component. Furthermore, by using multiple first magnetic fixing components to magnetically connect with the periphery of the steel structure component, the magnetic connection with the steel structure component has high stability.
[0008] In some embodiments, the base plate has recesses on both sides of the notch to form collection grooves, which are used to collect welding slag during the welding process.
[0009] In the above technical solution, by forming collection grooves on both sides of the notch of the base plate, the welding slag generated during the welding process falls onto the base plate or falls onto the base plate under the guidance of the side plate. The collection grooves can effectively collect the welding slag, allowing the welding slag accumulated on the base plate to move closer to the lower point of the collection groove, which is conducive to the concentrated collection of welding slag.
[0010] In some embodiments, a slag discharge port is provided at the center of the bottom of the collection tank, and a sealing cap is provided at the slag discharge port.
[0011] In the above technical solution, a slag discharge port is set at the bottom center of the collection tank, so that the welding slag collected by the collection plate can be discharged from the slag discharge port. During the welding process, the slag discharge port is sealed with a sealing cover. When it is necessary to discharge slag from the collection tank, the sealing cover can be opened and the collected welding slag can be discharged through the slag discharge port.
[0012] In some embodiments, the first magnetic fastener is mounted on the base plate by a guide assembly, the guide assembly including a guide cylinder and a guide post, the guide cylinder being fixedly connected to the bottom of the base plate, the guide post being closer to the notch than the guide cylinder, the guide cylinder having a guide cavity, at least a portion of the guide post being slidably disposed within the guide cavity, and the first magnetic fastener being fixedly connected to the end of the guide post away from the guide cylinder.
[0013] In the above technical solution, by setting the guide component, which includes a guide cylinder and a guide post, at least a portion of the guide post is slidably disposed in the guide cavity. Thus, after the first magnetic fastener is connected to the guide post, even if the size of the steel structure component changes, the first magnetic fastener can still actively approach the steel structure component and achieve magnetic connection with it by sliding the guide post relative to the guide cylinder. In other words, the setting of the guide component makes the position of the first magnetic fastener adjustable, which can adapt to the positioning and connection of more steel structure components of different sizes. It is only necessary to design the size of the notch to be slightly larger, and use the movement of the first magnetic fastener to adapt to steel structure components of different sizes.
[0014] In some embodiments, at least a portion of the opening of the notch is provided with a slag-blocking element, which includes two slag-blocking plates disposed opposite each other. The two slag-blocking plates are respectively disposed on opposite sides of the notch, one end of each slag-blocking plate is hinged to the opposite sides of the notch of the bottom plate, and the other end of the slag-blocking plate overlaps with the other end of the other slag-blocking plate. The two slag-blocking plates are in an inverted V shape. A spring is provided between each slag-blocking plate and the bottom plate, and the spring is used to provide support force to the slag-blocking plate.
[0015] In the above technical solution, the notch allows steel structural components to be inserted and magnetically connected to the collection tray. A slag-blocking component is installed at the notch location, effectively blocking at least a portion of the notch, requiring only the steel structural component to be avoided. This prevents welding slag from splashing out during welding, thus improving the collection efficiency of the collection tray. Specifically, two slag-blocking plates are positioned opposite each other on either side of the notch, with one end of each plate hinged to one side of the notch and the other end overlapping the other end of the other plate. A spring is installed between the slag-blocking plates and the base plate, providing support. This allows the two slag-blocking plates to partially block the welding slag from the notch. Furthermore, the inclined design of the slag-blocking plates guides the welding slag into the collection tank. When the collection tray needs to be inserted into the steel structure component, and the steel structure component comes into contact with the slag baffle, force is applied to continue squeezing the steel structure component towards the inside of the notch. This can push the two slag baffles apart on both sides. At this time, the spring accumulates elastic force. When the steel structure component is inserted into the corresponding position towards the inside of the notch, the steel structure component separates from the slag baffle, and the elastic force of the spring is reset, so that the two slag baffles fit together in an inverted V shape again, thereby achieving the purpose of blocking the welding slag.
[0016] In some embodiments, the slag baffle plate is spaced from the end of the notch away from the open side to form a clearance hole for the arrangement of steel structural members.
[0017] In the above technical solution, there is a gap between the slag baffle and the end of the gap away from the open side, that is, the slag baffle does not completely cover the gap, so the gap still has a clearance hole for the arrangement of steel structure components.
[0018] In some embodiments, a second magnetic fastener is provided between two adjacent side plates, and the magnetic properties of the second magnetic fasteners on the two adjacent side plates are opposite, so that the two adjacent side plates are magnetically connected.
[0019] In the above technical solution, by setting a second magnetic fastener between two adjacent side plates, that is, the two side plates are connected by the second magnetic fastener, the connection between the side plates is facilitated, and the assembly is convenient and quick.
[0020] In some embodiments, the side plate is hinged to the bottom plate, and the side plate has a vertical state and an unfolded state relative to the bottom plate. In the vertical state, the side plate is perpendicularly connected to the bottom plate, and in the unfolded state, the side plate and the bottom plate are coplanar.
[0021] In the above technical solution, the side plate and the bottom plate are hinged together, allowing them to rotate relative to each other. When the side plate and the bottom plate are in a vertical state, they are perpendicularly connected, making the collection tray suitable for collecting weld slag inserted into the welding points of the steel structure components. When the side plate and the bottom plate are in an unfolded state, they are coplanar, allowing the collection tray to be inserted into the lower part of the bottom of the steel structure component. This is suitable for welding larger areas, as the collection tray can be directly placed horizontally below the welding points of the steel structure component, enabling simultaneous collection of weld slag from multiple welding points. This provides a wider collection range, greater flexibility, and enhanced functionality.
[0022] In some embodiments, the bottom plate and the side plate have the same structure. The bottom plate includes a substrate and an asbestos cloth, the asbestos cloth is attached to the substrate and is located on the inner side of the collection tray.
[0023] In the above technical solution, the base plate and side plates adopt the same structure, which facilitates the rapid production and assembly of the collection tray. The base plate includes a base material and asbestos cloth. The base material provides strength, while the asbestos cloth is non-combustible and has high-temperature resistance. The collection tray can effectively block and collect welding slag, making the collection tray safer.

[0037] This application provides a steel structure welding slag collection device. Please refer to... Figures 1 to 5 The steel structure welding slag collection device 100 includes a collection tray 10 and a first magnetic fastener 20. The collection tray 10 includes a base plate 11 and a plurality of side plates 12. The plurality of side plates 12 are connected to at least two sides of the base plate 11, and at least one side of the base plate 11 is not provided with a side plate 12 to form an open side 13 of the collection tray 10. The base plate 11 is provided with a notch 111 on the open side 13. The notch 111 is used for the collection tray 10 to accommodate the steel structure component 200. The first magnetic fastener 20 is provided at the bottom of the base plate 11 and is located around the notch 111. The first magnetic fastener 20 is used to magnetically engage with the steel structure component 200 to position the collection tray 10 on the steel structure component 200.
[0038] In this design, the collection tray 10 includes a base plate 11 and a side plate 12. The base plate 11 has a notch 111, through which the collection tray 10 can be inserted into the steel structure component 200. Then, the first magnetic fastener 20 provided around the notch 111 of the base plate 11 is magnetically connected and fixed to the steel structure component 200. Since the steel structure component 200 is made of iron, the magnetic force of the first magnetic fastener 20 is used to magnetically engage with the steel structure component 200, thereby magnetically fixing the collection tray 10 to the steel structure component 200. The collection tray 10 is easy and quick to install and can be quickly disassembled from the steel structure component 200, improving welding efficiency. Furthermore, the side plate 12 on the collection tray 10 is connected to the base plate 11. The side plate 12 can effectively block the welding slag that splashes during the welding process, reducing the risk of burns to construction workers and making the process safer. After being blocked by the side plate 12, the splashed welding slag falls onto the base plate 11, completing the collection of welding slag. Construction workers do not need to collect the welding slag a second time, resulting in high construction efficiency.
[0039] In some embodiments, the first magnetic fastener 20 is a permanent magnet, and there are multiple first magnetic fasteners 20, all of which are magnetically connected to the periphery of the steel structure member 200. By using permanent magnets for the first magnetic fasteners 20, compared with electromagnets, permanent magnets have a simpler structure, lower cost, and can better achieve magnetic connection with the steel structure member 200. Furthermore, the magnetic connection with the steel structure member 200 is highly stable due to the multiple first magnetic fasteners 20.
[0040] In some embodiments, the base plate 11 has recessed collection grooves 112 on both sides of the notch 111, which are used to collect welding slag during the welding process. By forming collection grooves 112 on both sides of the notch 111 of the base plate 11, the welding slag generated during the welding process falls onto the base plate 11 or falls onto the base plate 11 under the guidance of the side plate 12. The collection grooves 112 can effectively collect the welding slag, allowing the welding slag accumulated on the base plate 11 to move closer to the lower point of the collection grooves 112, which is conducive to the concentrated collection of welding slag.
[0041] In some embodiments, a slag discharge port 113 is provided at the center of the bottom of the collecting tank 112, and a sealing cap is provided at the slag discharge port 113. By providing a slag discharge port 113 at the center of the bottom of the collecting tank 112, the welding slag collected by the collecting pan 10 can be discharged from the slag discharge port 113. During the welding process, the sealing cap is used to block the slag discharge port 113. When it is necessary to discharge slag from the collecting tank 112, the sealing cap can be opened to discharge the collected welding slag through the slag discharge port 113.
[0042] The sealing cap and the slag discharge port 113 can be connected by threads.
[0043] In some embodiments, the first magnetic fastener 20 is mounted on the base plate 11 via a guide assembly 30. The guide assembly 30 includes a guide cylinder 31 and a guide post 32. The guide cylinder 31 is fixedly connected to the bottom of the base plate 11. The guide post 32 is closer to the notch 111 than the guide cylinder 31. The guide cylinder 31 has a guide cavity. At least a portion of the guide post 32 is slidably disposed in the guide cavity. The first magnetic fastener 20 is fixedly connected to the end of the guide post 32 away from the guide cylinder 31. By setting the guide assembly 30, which includes a guide cylinder 31 and a guide post 32, at least a portion of the guide post 32 is slidably disposed in the guide cavity. Thus, after the first magnetic fixing member 20 is connected to the guide post 32, even if the size of the steel structure member 200 changes, the first magnetic fixing member 20 can still actively approach the steel structure member 200 and achieve magnetic connection with the steel structure member 200 by sliding the guide post 32 relative to the guide cylinder 31. In other words, the setting of the guide assembly 30 makes the position of the first magnetic fixing member 20 adjustable, which can adapt to the positioning and connection of more steel structure members 200 of different sizes. It is only necessary to design the size of the notch 111 to be slightly larger, and use the movement of the first magnetic fixing member 20 to adapt to steel structure members 200 of different sizes.
[0044] A limiting part is provided at the cavity opening of the guide cavity, and a blocking part is provided on the guide post 32. The blocking part and the limiting part cooperate to prevent the guide post 32 from separating from the guide cylinder 31, and they can only slide relative to each other.
[0045] In some embodiments, at least a portion of the opening of the notch 111 is provided with a slag-blocking member 40. The slag-blocking member 40 includes two opposing slag-blocking plates, which are respectively disposed on opposite sides of the notch 111. One end of each slag-blocking plate is hinged to the opposite sides of the notch 111 of the base plate 11, and the other end of each slag-blocking plate overlaps with the other end of the other slag-blocking plate. The two slag-blocking plates are in an inverted V-shape. A spring 41 is provided between each slag-blocking plate and the base plate 11 to provide support force to the slag-blocking plate. Since the notch 111 allows the steel structure member 200 to be inserted and magnetically connected to the collection tray 10, the slag-blocking member 40 can block at least a portion of the notch 111 by simply avoiding the steel structure member 200. This makes it less likely for welding slag generated during welding to splash out from the notch 111, thereby improving the slag collection effect of the collection tray 10. Specifically, two slag-blocking plates are positioned opposite each other on both sides of the notch 111, with one end of the slag-blocking plate hinged to one side of the notch 111 and the other end overlapping with the other end of the other slag-blocking plate. A spring 41 is provided between the slag-blocking plate and the base plate 11, which can provide support to the slag-blocking plate. This allows the two slag-blocking plates to block part of the welding slag in the notch 111. Furthermore, by using the inclined arrangement of the slag-blocking plates, the welding slag is guided into the collection tank 112. When the collecting tray 10 needs to be inserted into the steel structure component 200, and the steel structure component 200 contacts the slag-blocking plate, the steel structure component 200 is pressed further into the notch 111, which can push the two slag-blocking plates apart on both sides. At this time, the spring 41 accumulates elastic force. When the steel structure component 200 is inserted into the corresponding position into the notch 111, the steel structure component 200 separates from the slag-blocking plate, and the elastic force of the spring 41 is reset, so that the two slag-blocking plates are once again in an inverted V-shape, thereby achieving the blocking of welding slag.
[0046] In some embodiments, there is a gap between the slag baffle and the end of the notch 111 away from the open side 13 to form a clearance hole 114 for the steel structure member 200 to be arranged. The gap between the slag baffle and the end of the notch 111 away from the open side 13 means that the slag baffle does not completely cover the notch 111, so that the notch 111 still has a clearance hole 114 for the steel structure member 200 to be arranged.
[0047] At this time, the first magnetic fastener 20 is disposed around the clearance hole 114.
[0048] In some embodiments, a second magnetic fastener 50 is provided between two adjacent side plates 12. The magnetic properties of the second magnetic fasteners 50 on the two adjacent side plates 12 are opposite, so that the two adjacent side plates 12 are magnetically connected. By providing a second magnetic fastener 50 between two adjacent side plates 12, that is, by connecting the two side plates 12 through the second magnetic fastener 50, the connection between the side plates 12 is facilitated, and the assembly is convenient and quick.
[0049] In some embodiments, the side plate 12 is hinged to the bottom plate 11. The side plate 12 has a vertical state and an unfolded state relative to the bottom plate 11. In the vertical state, the side plate 12 is perpendicularly connected to the bottom plate 11. In the unfolded state, the side plate and the bottom plate 11 are coplanar. By hinged between the side plate 12 and the bottom plate 11, the side plate 12 and the bottom plate 11 can rotate relative to each other. When the side plate 12 and the bottom plate 11 are in the vertical state, the side plate 12 is perpendicularly connected to the bottom plate 11, so that the collection tray 10 can be adapted to collect weld slag inserted into the welding point of the steel structure member 200. When the side plate 12 and the bottom plate 11 are in the unfolded state, the side plate and the bottom plate 11 are coplanar. In this state, the collecting tray 10 can be inserted into the bottom side of the steel structure component 200. It is also suitable for welding of a large area. The collecting tray 10 can be directly placed horizontally below the welding point of the steel structure component 200. It can complete the synchronous collection of welding slag from multiple welding points, with a wider collection range, more flexible use, and stronger functionality.
[0050] In some embodiments, the base plate 11 and the side plates 12 have the same structure. The base plate 11 includes a substrate and asbestos cloth, with the asbestos cloth attached to the inner surface of the substrate and located on the inner surface of the collection tray 10. Using the same structure for the base plate 11 and the side plates 12 facilitates rapid production and assembly of the collection tray 10. The base plate 11, comprising a substrate and asbestos cloth, provides support. The base plate 11 and the side plates 12 contact the welding slag through the asbestos cloth on their inner surfaces. Since the asbestos cloth is non-combustible and has high-temperature resistance, the collection tray 10 can effectively block and collect the welding slag, thus enhancing the safety of the collection tray 10.
[0051] The substrate material can be of various types. For example, the substrate material can be plastic or non-magnetic metal, such as aluminum. The substrate material can be determined according to the actual situation.
[0052] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
