It transmits the load of purlin to the main structure through the connection with steel beam or steel column. The structure of purlin support plate usually adopts a rectangular plate welded with a triangular plate. The installation is realized by opening mounting holes on the rectangular plate. In the process of processing purlin support plate, the right angle edge of the triangular plate is welded at the middle position of the rectangular plate by welding.

DETAILED DESCRIPTION

[0023] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to explain the present application but not to limit the scope of the present application.

[0025] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms “mounting”, “connection” should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] As Figures 1 to 10As shown, the embodiment of the present application provides a steel structure welding device for building engineering, which comprises a welding table 1, a feeding mechanism 2, a rotating table 3, a purlin support plate limiting mechanism 4 and a welding device 5. The feeding mechanism 2 is arranged on the welding table 1, and the rotating table 3 is rotatably arranged on the welding table 1. The purlin support plate limiting mechanism 4 is arranged on the rotating table 3, and the purlin support plate limiting mechanism 4 comprises a triangular plate limiting 41 component and two rectangular plate limiting insert plates 42. The rotating table 3 can rotate to move the two rectangular plate limiting insert plates 42 to the discharge end 23 of the feeding mechanism 2 respectively, so that the feeding mechanism 2 can transfer two rectangular plates 100 to the two rectangular plate limiting insert plates 42 respectively in turn, and transfer two triangular plates 200 to the triangular plate limiting 41 component, so that the two triangular plates 200 are in contact with the corresponding rectangular plates respectively. The welding device 5 is arranged on the welding table 1 and is used for welding the triangular plates and the rectangular plates 100 matched on the purlin support plate limiting mechanism 4.

[0027] When the steel structure welding device for building engineering provided by the present application is used, the rotating table 3 first drives one of the rectangular limiting insert plates and the triangular limiting component to correspond to the discharge end 23 of the feeding mechanism 2. The feeding mechanism 2 pushes a set of well-positioned purlin support plates into the triangular plate limiting 41 component and one of the rectangular plate limiting insert plates 42. The rotating table 3 rotates again to correspond to the discharge end 23 of the feeding mechanism 2 on the other side of the other rectangular limiting insert plate and the triangular limiting component. The feeding mechanism 2 pushes another set of well-positioned purlin support plates into the other side of the triangular plate limiting 41 component and the other rectangular plate limiting insert plate 42. In this way, the welding device 5 can simultaneously weld two purlin support plates, thereby improving the welding efficiency.

[0028] Through the arrangement of the rotating table 3, the feeding mechanism 2 and other structures, the combined purlin support plates can be pushed into the insert plates and the limiting mechanism. Through the arrangement of the rotating mechanism, the disc can be rotated to rotate the combined purlin support plates to the upper side. Then, another set of purlin support plates can be combined and pushed in. Subsequently, a welding mechanical arm can be used to automatically weld the two sets of combined purlin support plates, thereby realizing the rapid welding of the two sets of purlin support plates, greatly improving the welding efficiency and reducing the production cost.

[0029] In addition, through the arrangement of the rotating table 3 and the purlin support plate limiting mechanism 4, the rapid positioning and clamping of the purlin support plates can be realized, and the precision and stability of the welding are improved. At the same time, the design of the purlin support plate limiting mechanism 4 also enables the triangular plates 200 and the rectangular plates 100 to be stably matched together, avoiding problems such as displacement or misalignment during the welding process, and further ensuring the welding quality. Therefore, the steel structure welding device for building engineering provided by the present application has the advantages of simple structure, convenient operation, high welding efficiency, stable welding quality and the like, can meet the welding processing needs of a large number of purlin support plates, and has a wide application prospect.

[0030] In some possible embodiments, the rotating table 3 has a hollow part 31, and two rectangular plate limiting insertion plates 42 are arranged on the same side of the rotating table 3 and on opposite sides of the hollow part 31. The triangular plate limiting 41 assembly is at least partially arranged between the two rectangular plate limiting insertion plates 42, and the triangular plate limiting 41 assembly and the two rectangular plate limiting insertion plates 42 form triangular plate limiting 41 spaces therebetween, respectively. During rotation of the rotating table 3, the two triangular plate limiting 41 spaces are respectively communicated with the discharge end 23, so that the feeding mechanism 2 can sequentially transfer two triangular plates 200 into the two triangular plate limiting 41 spaces, respectively. The design of the triangular plate limiting 41 spaces cooperates with each other, so that the purlin supporting plate can be stably clamped, and problems such as slipping or mispositioning during the transfer process are avoided, further ensuring the accuracy and stability of welding. At the same time, the automatic operation of the feeding mechanism 2 greatly improves the welding efficiency and reduces the tediousness and errors of manual operation.

[0031] In some possible embodiments, the rectangular plate limiting insertion plate 42 has a T-shaped slot, and a strip-shaped slot of the T-shaped slot is communicated with the triangular plate limiting 41 space. In a state where the rectangular plate 100 is inserted into the T-shaped slot and the triangular plate 200 is inserted into the triangular plate limiting 41 space, a right-angle plate of the triangular plate 200 is attached to the rectangular plate 100. The design of the T-shaped slot not only facilitates the quick positioning and insertion of the rectangular plate 100, but also enhances the stability of the purlin supporting plate structure by the attachment of the right-angle plate. And the attachment of the triangular plate 200 and the rectangular plate 100 leaves a clearance space.

[0032] In some possible embodiments, the triangular plate limiting 41 assembly includes a limiting plate 411 and an auxiliary limiting mechanism 412. The limiting plate 411 is provided with inclined edges on both sides, respectively, and the two inclined edges form triangular plate limiting 41 spaces with the corresponding rectangular plate limiting insertion plates 42, respectively. The limiting plate 411 is provided with a first blocking rib 413 on one side in the thickness direction, the first blocking rib 413 protrudes from the corresponding inclined edge, the auxiliary limiting mechanism 412 is arranged on the side of the triangular plate 200 away from the first blocking rib 413, the auxiliary limiting mechanism 412 can protrude from or be away from the first blocking edge, and the auxiliary limiting mechanism 412 and the first blocking rib 413 can be respectively limited on both sides in the thickness direction of the triangular plate 200. The inclined edge of the triangular plate is attached to the inclined edge on one side of the limiting plate 411, one right-angle edge of the triangular plate is attached to the rectangular plate 100, and the other right-angle edge is pushed by the feeding mechanism 2.

[0033] This design makes the position of the triangular plate 200 in the limiting space more accurate, further enhancing the stability of the purlin support plate structure during assembly before welding. When the triangular plate 200 is sent into the limiting space, the auxiliary limiting mechanism 412 and the first blocking rib 413 can resist the two sides of the triangular plate 200, preventing the triangular plate 200 from falling out of the triangular plate limiting space 41. At the same time, the auxiliary limiting mechanism 412 is movable and can present a state of blocking the triangular plate 200 or a state of not blocking the triangular plate 200. When the welding is completed, the auxiliary limiting mechanism 412 can be switched to the state of not blocking.

[0034] In some possible embodiments, the auxiliary limiting mechanism 412 includes a first telescopic component 4121 and a second blocking rib 4122. The first telescopic component 4121 is arranged on the limiting plate 411, and the second blocking rib 4122 is arranged on the telescopic end of the first telescopic component 4121. The first telescopic component 4121 can be extended to make the second blocking rib 4122 extend beyond the hypotenuse, and the first telescopic component 4121 can be retracted to make the second blocking rib 4122 move away from the hypotenuse. Since the hypotenuse is inclined, the state switching between blocking and not blocking can be realized by horizontally moving the second blocking rib 4122.

[0035] Further, a sliding groove is arranged on the limiting plate 411, and a sliding block is arranged on the second blocking rib 4122, which is slidably arranged in the sliding groove.

[0036] In some possible embodiments, the triangular plate limiting assembly 41 includes a second telescopic component 414, and the limiting plate 411 is slidably connected to the rotating table 3. The second telescopic component 414 is arranged on the rotating table 3, and the second telescopic component 414 and the limiting plate 411 are connected to drive the limiting plate 411 to move to or deviate from the discharge end 23 of the feeding mechanism 2. When the purlin support plate is in the assembled state, the second telescopic component 414 drives the limiting plate 411 and the auxiliary limiting mechanism 412 to be positioned between the two rectangular plates 100, and the triangular plate 200 is positioned. After welding is completed, in order to facilitate the removal of the purlin support plate, the limiting plate 411 is moved to the side edge of the rectangular plate limiting slot 42, improving the convenience of welding and taking out.

[0037] In some possible embodiments, the feeding mechanism 2 has a pushing component 21 and a storage rack 22, the storage rack 22 has a triangular plate storage cavity 221 and a rectangular plate storage cavity 222, the pushing component 21 has an extendable rod 211 and a pushing plate 212 arranged at the end of the extendable rod 211. The extendable rod 211 is extended to push the triangular plate 200 in the triangular plate storage cavity 221 and the rectangular plate 100 in the rectangular plate storage cavity 222 by the pushing plate 212, so that the rectangular plate 100 is inserted into the rectangular plate limiting insertion plate 42, the triangular plate 200 is inserted into the triangular plate limiting 41 assembly, and the joint part of the triangular plate 200 and the rectangular plate 100 is exposed to the purlin support plate limiting mechanism 4. Through the arrangement of the pushing component 21, the triangular plate 200 and the rectangular plate 100 can be automatically pushed into the corresponding limiting space, without manual carrying and assembling, so that the work efficiency and safety are greatly improved. At the same time, the design of the storage rack 22 also makes the triangular plate 200 and the rectangular plate 100 be orderly stored, so that the triangular plate 200 and the rectangular plate 100 are convenient to take and manage.

[0038] In some possible embodiments, the triangular plate storage cavity 221 is located at the top of the rectangular plate storage cavity 222, so that the rectangular plate 100 is conveniently fed from bottom to top. The connecting seam connecting the triangular plate storage cavity 221 is arranged at the top of the rectangular plate storage cavity 222, so that the triangular plate 200 is pushed to fall on the rectangular plate 100 and be attached to the rectangular plate 100. The pushing plate 212 of the pushing component 21 includes a horizontal plate part 2121 and a vertical plate part 2122 perpendicular to the horizontal plate part 2121. When the pushing component 21 is extended, the horizontal plate part 2121 is located in the rectangular plate storage cavity 222 and abuts against the thickness end face of the rectangular plate, the vertical plate part 2122 penetrates through the connecting seam and is located in the triangular plate storage cavity 221 and abuts against the thickness end face of the triangular plate 200, so that the feeding process is more smooth.

[0039] In some possible implementation, the welding device for building engineering steel structure comprises a third telescopic component 6 and a fourth telescopic component 7. The third telescopic component 6 is arranged on the welding table 1, and the end of the third telescopic component 6 extends into the rectangular plate storage cavity 222, and the rectangular plates 100 in the rectangular plate storage cavity 222 are stacked in sequence along the telescopic direction of the third telescopic component 6. The fourth telescopic component 7 is arranged on the storage rack 22, and the end of the fourth telescopic component 7 extends into the triangular plate storage cavity 221, and the triangular plates 200 in the triangular plate storage cavity 221 are stacked in sequence along the telescopic direction of the fourth telescopic component 7. Such arrangement can realize automatic feeding, and further improve the automation degree of the welding device. The telescopic action of the third telescopic component 6 and the fourth telescopic component 7 can respectively push the rectangular plates 100 and the triangular plates 200 to move forward, so that the plates to be welded can be sequentially fed to the pushing component 21. When the pushing component 21 performs the pushing action, the rectangular plates 100 and the triangular plates 200 can be respectively pushed into the rectangular plate limiting plug-in plate 42 and the triangular plate limiting plug-in plate 41 assembly, and the preparation for assembling the purlin support plate is completed. The automatic feeding design not only improves the work efficiency, but also reduces the intervention of manual operation, thereby reducing the risk of operation failure, and ensuring the stability and reliability of the welding process.

[0040] Further, the rectangular plate storage cavity 222 is provided with a lower pushing plate 223, the triangular plate storage cavity 221 is provided with a side pushing plate 224, the ends of the third telescopic component 6 and the fourth telescopic component 7 are respectively connected with the lower pushing plate 223 and the side pushing plate 224, and the telescopic action of the third telescopic component 6 and the fourth telescopic component 7 can drive the rectangular plates 100 and the triangular plates to move to the discharge end 23 through the lower pushing plate 223 and the side pushing plate 224. The arrangement of the pushing plate and the side pushing plate 224 can improve the contact area with the rectangular plates 100 and the triangular plates 200, and improve the stable effect of pushing the rectangular plates 100 and the triangular plates 200.

[0041] In some possible embodiments, the device for welding steel structure of building engineering comprises a pushing mechanism 8 and two carriers 9. The carriers 9 are movably arranged in the hollow part 31, and a first reset spring 10 is connected between the carriers 9 and the rotating table 3. The rectangular plate limiting insert plate 42 is slidably connected to the carrier 9, the pushing piece 12 is slidably penetrated through the carrier 9, one end of the pushing piece 12 is connected to the rectangular plate limiting insert plate 42, and the other end of the pushing piece 12 is provided with a pushing matching part 13. The second reset spring 11 is arranged on the inner wall of the carrier 9 and the rectangular plate limiting insert plate 42. The pushing mechanism 8 is arranged on the welding table 1, and the pushing mechanism 8 acts on the pushing matching part 13 to make the corresponding rectangular plate limiting insert plate 42 move sideways and make the two rectangular plate limiting insert plates 42 move towards each other. The pushing matching part 13 comprises a first matching inclined surface 131, the pushing mechanism 8 comprises a fifth telescopic part 82 and a pushing block 81 arranged at one end of the fifth telescopic part 82, the fifth telescopic part 82 drives the pushing block 81 to ascend and descend, the pushing block 81 comprises a second matching inclined surface 811 and a downward pressing surface 812, and in the state that the pushing mechanism 8 extends downwards, the first matching inclined surface 131 of the pushing block 81 and the second matching inclined surface 811 are matched to push the rectangular plate limiting insert plate 42 to move sideways until the downward pressing surface 812 abuts against the rectangular plate limiting insert plate 42, so that the rectangular plate limiting insert plate 42 at the top moves downwards.

[0042] When it is needed to remove the purlin support plates after welding, the pushing mechanism 8 pushes the second matching inclined surface 811 through the first matching inclined surface 131 to drive one of the rectangular plate limiting insert plates 42 to move sideways, so that the triangular plates 200 of the two purlin support plates are misaligned. The pushing mechanism 8 continues to extend, the downward pressing surface 812 of the pushing block 81 continuously abuts against the rectangular plate limiting insert plate 42, so that the rectangular plate limiting insert plate 42 moves downwards against the elastic force of the first reset spring 10, thereby driving the carrier 9 to move downwards together, so that the two purlin support plates are close to each other, and then the operator can conveniently remove the two purlin support plates after welding at the same time. After the purlin support plates are removed, the rectangular plate limiting insert plate 42 of the pushing piece 12 is reset to the initial position after the side movement under the action of the first reset spring 10 and the second reset spring 11 in the pushing piece 12 and the inner wall of the carrier 9.

[0043] In addition, in order to further improve the automation degree and operation convenience of the welding device, some auxiliary mechanisms can be arranged. For example, a detection sensor for detecting whether the purlin support plate is assembled can be arranged on the welding table 1, and when the detection sensor detects that the purlin support plate is correctly assembled, the welding equipment 5 can be triggered to perform welding operation.
