Technical Field

[0001] This invention relates to the field of steel component welding technology, and in particular to a welding equipment for large steel components with a rust removal structure. Background Technology

[0002] A steel structure is a building skeleton made of steel, and it is a very mainstream building form nowadays. It is mainly supported by steel beams, steel columns, and steel trusses. The components are connected together by welding, bolts, or rivets. The advantages of steel structures are that steel is high-strength and lightweight, and construction can be fast while reducing construction costs. Before production, steel components need to be spliced ​​and connected by welding.

[0003] Currently, when welding steel structures using existing technologies, it is necessary to connect the sealing steel plate and the open part of the U-shaped steel structure together by welding. Due to the large size of the steel components, it is not easy to calibrate during welding, resulting in unevenness when the sealing steel plate and the open part of the U-shaped steel structure are connected. Therefore, this invention proposes a welding equipment for large steel components with a rust removal structure. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art where, when welding steel structures, the sealing steel plate and the open part of the U-shaped steel structure need to be connected together by welding. Due to the large size of the steel components, it is not easy to calibrate during welding, resulting in unevenness when the sealing steel plate and the open part of the U-shaped steel structure are connected.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a large steel component welding equipment with a rust removal structure, comprising a support mechanism, a feeding mechanism mounted on the support mechanism, and a supporting mechanism mounted on the support mechanism. The feeding mechanism is connected to the supporting mechanism for feeding and supporting the steel component. The support mechanism includes a supporting base plate, two partitions are fixedly connected to both sides of the upper surface of the supporting base plate, a processing chamber is provided between the partitions, two supporting rollers are rotatably mounted at both ends of the processing chamber, an arched bracket is fixedly connected to the upper surface of the partitions, and a mechanical welding arm is fixedly connected to the middle of one side of the supporting base plate.

[0006] In at least some embodiments, the feeding mechanism includes a lifting bracket located between a partition and an arched bracket. The inner wall of the lifting bracket is fixed with four evenly distributed slide rails. Side baffles are slidably installed in the slide rails, and two of the side baffles are located on both sides of the lifting bracket.

[0007] In at least some embodiments, a shaped bracket is rotatably mounted on one end of the side baffle, the shaped bracket is located at the four corners of the shaped bracket, and a rotating component is fixedly connected to the lower end of each shaped bracket. The shaped bracket is rotatably mounted on the outer wall of the support base plate through the rotating component.

[0008] In at least some embodiments, a connecting seat is fixedly connected to the inner side of the irregular bracket, an L-shaped connecting rod is rotatably installed in the connecting seat, one end of the L-shaped connecting rod is rotatably installed on the outer side wall of the lifting bracket, and connecting members are fixedly connected to both sides of the upper surface of the lifting bracket. An electric push rod output shaft is fixedly connected to one end of the connecting member, and the electric push rod is fixedly connected to the upper surface of the support base plate.

[0009] In at least some embodiments, the support mechanism includes an assembly plate fixed to the lower surface of the arched bracket, a transverse plate below the assembly plate, and two slide rails fixed to both sides of the upper surface of the transverse plate.

[0010] In at least some embodiments, the transverse plate is slidably mounted on the lower end of the assembly plate via a second slide rail, a support plate is fixedly connected to one end of the assembly plate, a rust removal laser device is fixedly connected to one side of the assembly plate, and a lower toothed plate is fixedly connected to the middle of the upper surface of the transverse plate.

[0011] In at least some embodiments, a lower mounting seat is fixedly connected to the other side of the assembly plate, and an upper mounting seat is provided above the lower mounting seat. The upper mounting seat is fixedly connected to one side surface of the arched bracket, and a driven gear and a transmission gear are respectively fixedly connected to the upper mounting seat and the lower mounting seat through a rotating shaft.

[0012] In at least some embodiments, sprockets are fixedly connected to the rotating shafts of the upper and lower mounting bases, chains are drivenly mounted on the two sprockets, the transmission gear and the lower gear plate are meshed together, the driven gear is meshed with an upper gear plate on one side, an extension plate is fixedly connected to one side of the upper gear plate, and the extension plate is fixedly connected to the outer wall of the arched bracket.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, the electric push rod can drive the lifting bracket to rise and fall along the partition through the connecting piece. The lifting bracket is slidably installed with side baffles through the No. 1 slide rail on the inner side wall. During the descent of the lifting bracket, the L-shaped connecting rod on its outer side is connected to the irregular bracket through the connecting seat, which can push the irregular bracket outward, so that the irregular bracket rotates around the rotating part, thereby dragging the two side baffles to move horizontally along the No. 1 slide rail, increasing the distance between the side baffles. Then the sealing steel plate will fall into the processing chamber, realizing the feeding of the sealing steel plate.

[0014] 2. In this invention, the assembly plate and the transverse plate descend simultaneously with the lowering of the lifting bracket. The assembly plate and the transverse plate move to both sides of the U-shaped steel structure, thus fixing both sides of the U-shaped steel structure. Rust removal is performed on the welded parts using a rust-removing laser on the surface of the assembly plate. At the same time, the driven gear on the upper mounting base meshes with the upper gear plate, which drives the transmission gear to rotate via the sprocket and chain. The transmission gear meshes with the lower gear plate, which pushes the transverse plate to move horizontally along the second slide rail. This moves the support plate at one end of the transverse plate into the U-shaped steel structure, thus supporting the sealing steel plate and connecting the sealing steel plate to the U-shaped steel structure. This prevents the sealing steel plate from bending due to gravity and improves the accuracy of steel structure welding. Attached Figure Description

Detailed Implementation

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0019] In existing technologies, the structure is a building skeleton made of steel, which is a very mainstream building form. It is mainly supported by steel beams, steel columns, and steel trusses, which are connected together by welding, bolts, or rivets. The advantages of steel structures are that steel is high-strength and lightweight, allowing for fast construction and reduced construction costs. Before production, steel components need to be spliced ​​together by welding. When welding the steel structure, the sealing steel plate and the open part of the U-shaped steel structure need to be connected by welding. Due to the large size of the steel components, it is not easy to calibrate during welding, which can lead to unevenness when the sealing steel plate and the open part of the U-shaped steel structure are connected.

[0020] Therefore, the objective of this invention is at least as follows: the U-shaped steel structure to be welded is placed in the processing chamber 105 of the support mechanism 100, and the steel plate to be sealed is placed in the feeding mechanism 200. The feeding mechanism 200 can drive the steel plate to be transported onto the U-shaped steel structure, and at the same time, the parts to be connected are derusted, thereby preparing for the subsequent welding of steel components. Meanwhile, the feeding mechanism 200 and the linkage support mechanism 300 can support and fix the transported steel plate to prevent bending due to gravity and improve the accuracy of steel structure welding.

[0021] Example, according to Figures 1-7 This invention provides a welding equipment for large steel components with a rust removal structure, including a support mechanism 100, a feeding mechanism 200 mounted on the support mechanism 100, and a supporting mechanism 300 mounted on the support mechanism 100. The feeding mechanism 200 is connected to the supporting mechanism 300 for feeding and supporting the steel component. Figure 2 As shown, the support mechanism 100 includes a support base plate 101. Two partitions 102 are fixedly connected to both sides of the upper surface of the support base plate 101. A processing chamber 105 is provided between the partitions 102. Two support rollers 103 are rotatably installed at both ends of the processing chamber 105. An arched bracket 104 is fixedly connected to the upper surface of the partitions 102. A mechanical welding arm 106 is fixedly connected to the middle of one side of the support base plate 101. During the steel structure welding process, the U-shaped steel structure support is pushed into the processing chamber 105, so that the workpiece moves horizontally within the processing chamber 105 through the support rollers 103.

[0022] like Figures 3-4As shown, the feeding mechanism 200 includes a lifting bracket 205, which is located between the partition plate 102 and the arched bracket 104. Four evenly distributed first slide rails 206 are fixedly connected to the inner wall of the lifting bracket 205. Side baffles 207 are slidably installed within the first slide rails 206. Two side baffles 207 are located on both sides of the lifting bracket 205. A shaped bracket 202 is rotatably installed at one end of each side baffle 207. The shaped brackets 202 are located at their four corners. A rotating component 201 is fixedly connected to the lower end of each shaped bracket 202. The shaped bracket 202 is rotatably installed on the outer wall of the support base plate 101 via the rotating component 201. A connecting seat 203 is fixedly connected to the inner side of the shaped bracket 202. An L-shaped connecting rod 204 is rotatably installed within the connecting seat 203. One end of the L-shaped connecting rod 204 is rotatably installed on the outer wall of the lifting bracket 205. Two... A connector 208 is fixedly connected to the side, and an output shaft of an electric push rod 209 is fixedly connected to one end of the connector 208. The electric push rod 209 is fixedly connected to the upper surface of the support base plate 101. The sealing steel plate that needs to be welded to the U-shaped steel structure support is placed on the side baffle 207. Activating the electric push rod 209, via the connector 208, can drive the lifting bracket 205 to rise and fall along the partition 102. The lifting bracket 205 is slidably mounted on the first slide rail 206 on the inner side wall. During the descent of the lifting bracket 205, the L-shaped connecting rod 204 on the outer side of the side baffle 207 is connected to the irregular bracket 202 through the connecting seat 203. This pushes the irregular bracket 202 outward, causing it to rotate around the rotating component 201. This drags the two side baffles 207 horizontally along the first slide rail 206, increasing the distance between the side baffles 207. Subsequently, the sealing steel plate will fall into the processing chamber 105, thus realizing the feeding of the sealing steel plate.

[0023] like Figures 6-7As shown, the support mechanism 300 includes an assembly plate 303, which is fixed to the lower surface of the arched bracket 104. A transverse plate 305 is provided below the assembly plate 303. Secondary slide rails 304 are fixed to both sides of the upper surface of the transverse plate 305. The transverse plate 305 is slidably mounted on the lower end of the assembly plate 303 via the secondary slide rails 304. A support plate 306 is fixed to one end of the assembly plate 303. A rust removal laser device 310 is fixed to one side of the assembly plate 303. A lower toothed plate 3 is fixed to the middle of the upper surface of the transverse plate 305. 07. A lower mounting base 311 is fixedly connected to the other side of the assembly plate 303. An upper mounting base 308 is provided above the lower mounting base 311. The upper mounting base 308 is fixedly connected to one side surface of the arched bracket 104. A driven gear 309 and a transmission gear 313 are respectively fixedly connected to the upper mounting base 308 and the lower mounting base 311 through a rotating shaft. A sprocket 312 is fixedly connected to the rotating shaft of both the upper mounting base 308 and the lower mounting base 311. A chain 314 is driven and mounted on the two sprockets 312. The transmission gear 313 and the lower gear plate 3... The driven gear 309 is meshed with an upper gear plate 302 on one side, and an extension plate 301 is fixedly connected to one side of the upper gear plate 302. The extension plate 301 is fixed to the outer wall of the arched bracket 104. As the lifting bracket 205 descends, the assembly plate 303 and the transverse plate 305 descend synchronously. The assembly plate 303 and the transverse plate 305 move to both sides of the U-shaped steel structure, thereby fixing both sides of the U-shaped steel structure. The welded parts are then derusted using a rust-removing laser instrument 310 on the surface of the assembly plate 303. Simultaneously, the driven gear 309 on the upper mounting base 308 meshes with the upper gear plate 302, which drives the transmission gear 313 to rotate via the sprocket 312 and chain 314. The transmission gear 313 meshes with the lower gear plate 307, which pushes the transverse plate 305 to move horizontally along the second slide rail 304, so that the support plate 306 at one end of the transverse plate 305 moves into the U-shaped steel structure, which can support the sealing steel plate and connect the sealing steel plate and the U-shaped steel structure together, preventing the sealing steel plate from bending due to gravity and improving the accuracy of steel structure welding.

[0024] The working principle of this invention is as follows: The sealing steel plate that needs to be welded to the U-shaped steel structure support is placed on the side baffle 207. Activating the electric push rod 209, via the connector 208, drives the lifting bracket 205 to rise and fall along the partition 102. The side baffle 207 is slidably mounted on the lifting bracket 205 via the first slide rail 206 on the inner wall. During the descent of the lifting bracket 205, its outer L-shaped connecting rod 204 is connected to the irregular bracket 202 via the connecting seat 203, thus pushing the irregular bracket 202 outwards. This causes the irregular bracket 202 to rotate around the rotating component 201, thereby dragging the two side baffles 207 horizontally along the first slide rail 206, increasing the distance between the side baffles 207. Subsequently, the sealing steel plate falls into the processing chamber 105, realizing the feeding of the sealing steel plate. Simultaneously with the descent of the lifting bracket 205... Simultaneously, the assembly plate 303 and the transverse plate 305 descend, moving to both sides of the U-shaped steel structure to fix them in place. The welding area is then rust-removed using a rust-removing laser instrument 310 on the surface of the assembly plate 303. Simultaneously, the driven gear 309 on the upper mounting base 308 meshes with the upper toothed plate 302, driving the transmission gear 313 to rotate via the sprocket 312 and chain 314. The transmission gear 313 meshes with the lower toothed plate 307, pushing the transverse plate 305 horizontally along the second slide rail 304. This moves the support plate 306 at one end of the transverse plate 305 into the U-shaped steel structure, supporting the sealing steel plate and connecting it to the U-shaped steel structure. This prevents the sealing steel plate from bending due to gravity and improves the accuracy of the steel structure welding.

[0025] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
