[0002] Steel structure is a structure composed of steel materials, and is one of the main building structure types. The structure is mainly composed of members such as steel beams, steel columns, steel trusses and the like made of shaped steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welding, bolts or rivets are usually used to connect between each member or part. Because the self weight is relatively light, and the construction is simple, the steel structure is widely used in fields such as large workshops, venues, super high-rise buildings, and bridges. The steel structure is prone to rust, and generally needs to be rusted, galvanized or painted, and needs to be maintained regularly.

[0045] After the steel structure 3 is accurately placed on the bearing assembly, the two turnover assemblies move the two clamping assemblies and make the two clamping assemblies clamp the steel structure 3, in the process of moving the two clamping assemblies, the two lifting assemblies also move synchronously, when the two clamping assemblies support and clamp the steel structure 3, the two lifting assemblies will open the bearing assembly because the distance of movement reaches, so that the bearing assembly loses the supporting force of the two lifting assemblies, so that the bearing assembly will descend and will not contact the bottom of the steel structure 3.

[0046] After the two clamping assemblies clamp the steel structure 3 completely, the two turnover assemblies will overturn the two clamping assemblies by 180°, so that the clamped steel structure 3 will be turned over. After the steel structure 3 is turned over, the two turnover assemblies will retract the two clamping assemblies to reset, and at the same time, the two lifting assemblies will also retreat to reset. In this way, the bearing assembly will complete the reset before the two clamping assemblies are separated from the steel structure 3, and support the steel structure 3 again.

[0068] When the servo motor 14 is started, the rotating disc 502 connected with the output shaft will rotate, and the rotating disc 502 will rotate in the rotating groove of the fixed plate 501 and be limited by the second sliding groove matched with the limiting strip 13, so that the stability of the rotating disc 502 can be ensured, and the deviation of the rotating disc 502 can be avoided.

[0069] A plurality of fixing holes are formed in the side of the rotating disc 502 close to the mounting disc 401, and a supporting rod 15 is fixedly installed in each fixing hole. The connecting end of each supporting rod 15 is fixedly installed with the mounting disc 401.

[0070] The supporting rod 15 will be fixedly installed in the fixing hole of the rotating disc 502, and after the supporting end is connected with the mounting disc 401, the stability and supporting force of the mounting disc 401 will be increased.

[0071] Working principle: When the staff starts to use the device to place the steel structure 3 on the supporting plate 701 for machining, when one side of the groove machining is completed, the staff needs to turn over the steel structure 3, and simultaneously starts the two oil cylinders 503, so that the output ends of the two oil cylinders 503 push the mounting disc 401 to move forward, so that the clamping base 402 also moves towards the direction of the steel structure 3.

[0072] After the second pushing block 10 contacts with the steel structure 3, the second pushing block 10 will be extruded to move backward with the continuous pushing of the oil cylinder 503, and the first pushing block 9 fixedly installed on one side of the second pushing block 10 will move, and the first pushing block 9 will move backward. The first pushing block 9 cooperates with the first sliding groove and the inclined surface of the two sliding blocks 403 to drive the two sliding blocks 403. Because the opposite surfaces of the two sliding blocks 403 are outwardly inclined, when the first pushing block 9 moves, it will push the inclined surface of the sliding block 403, so as to extrude the two sliding blocks 403 outward, so that the two sliding blocks 403 move towards each other. The two clamping blocks 404 will move closer to each other due to the approaching of the two sliding blocks 403, so that the two clamping blocks 404 approach each other to clamp and fix the two sides of the steel structure 3. The more forceful the abutment between the steel structure 3 and the second pushing block 10, the greater the clamping force of the two clamping blocks 404 on the steel structure 3.

[0073] When the two clamping blocks 404 are not fully clamped in support of the steel structure 3, that is, when the mounting disc 401 moves towards the steel structure 3, the third pushing block 17 will also move in the same direction, so that the third pushing block 17 will drive the fourth pushing block 18 to move, and the fourth pushing block 18 will push the fifth pushing block 19. When the fifth pushing block 19 moves, the roller 21 will move, and the roller 21 will move along the inner wall of the pushing groove 20. When the fifth pushing block 19 continuously moves with the roller 21, it will push the pushing groove 20 due to the inclined inner wall of the pushing groove 20, so that the support block 703 as the carrier of the pushing groove 20 will be pushed, so that the two support blocks 703 will move away from each other due to the pushing of the fifth pushing block 19 and the roller 21.

[0074] When the two support blocks 703 move away from each other, the two second lifting plates 803 will be pulled to the two sides, so that the first lifting plate 802 hinged to the two second lifting plates 803 will be lowered in height, and the lowering of the height of the first lifting plate 802 will press the lifting spring 801, so that the support force of the two support blocks 703, the lifting spring 801 and the first lifting plate 802 on the limiting plate 702 will disappear, so that the limiting plate 702 will bring the support plate 701 to descend from the support hole 35 to the inside of the movable groove 6, and when the two support blocks 703 move away from each other, the connecting column 32 will be pushed to move inside the spring sleeve 31, and the reset spring 33 inside will be compressed, so that the reset spring 33 remains in a compressed state.

[0075] At this time, although there is no support of the support block 703, the clamping block 404 will maintain support for the steel structure 3. When the output end of the oil cylinder 503 is pushed to the set length, the clamping block 404 will maintain support for the steel structure 3, and the clamping on both sides will limit the position of the steel structure 3, so that the steel structure 3 remains in the slotted position.

[0076] At the same time that the third pushing block 17 pushes the fourth pushing block 18, the connecting plate 24 is fixedly connected with the third pushing block 17, so it will move together with the third pushing block 17, so as to pull the clamping plate 25 to move together. When the clamping plate 25 moves, it will move out of the clamping groove 30 of the rotating disc 502, so that the rotating disc 502 will lose the limit and can rotate.

[0077] After the rotating disc 502 can rotate, the staff can open two servo motors 14 at the same time, and the two servo motors 14 can rotate the output shaft by 180° according to the setting, so that the rotating disc 502 also rotates by 180°. The rotating disc 502 rotates to drive the mounting disc 401, the clamping base 402, the sliding block 403 and the clamping block 404 to rotate together. Finally, since the steel structure 3 is clamped and fixed by the clamping block 404, it also rotates by 180°, so that the steel structure 3 is turned over.

[0078] After the steel structure 3 is turned over, the staff drives the output end of the two oil cylinders 503 to retract, so that the mounting disc 401 moves away from the steel structure 3. After the mounting disc 401 moves, the clamping base 402 also moves, so that the second pushing block 10 gradually separates from the steel structure 3. When the steel structure 3 is completely separated, the steel structure 3 is only supported by the clamping block 404. The pushing spring 12 pushes the first pushing block 9 outward, and the first pushing block 9 pushes the two sliding blocks 403 to move away from each other, so that the two clamping blocks 404 gradually move away from the steel structure 3.

[0079] During the retraction of the oil cylinder 503, when the clamping block 404 has not separated from the steel structure 3, the third pushing block 17 moves with the mounting disc 401, so that the fourth pushing block 18 pulls the fifth pushing block 19 to move together, so that the fifth pushing block 19 and the roller 21 move together towards the direction of the adjacent pushing groove 20. Since the length of the inclined surface of the pushing groove 20 is short, after the fifth pushing block 19 and the roller 21 move a certain distance, they directly change from being in contact with the support block 703 to being in contact with the inner wall of the pushing groove 20. When the fifth pushing block 19 and the roller 21 directly enter the inside of the pushing groove 20, the two support blocks 703 lose the outward pushing force, so that the return spring 33 expands to push the connecting column 32, which pushes the support block 703, so that the support block 703 returns to the original position.

[0080] When the two support blocks 703 are reset, the two support blocks 703 move towards each other. During the movement, the lifting spring 801 lifts the first lifting plate 802, so that the first lifting plate 802 lifts the limiting plate 702. As the two support blocks 703 gradually return to the initial position, the lifting spring 801 cooperates with the first lifting plate 802 to gradually lift the limiting plate 702 completely, and finally the limiting plate 702 can be placed on the two support blocks 703, so that the support plate 701 supports the steel structure 3 through the support hole 35.

[0081] With the movement of the third pushing block 17, the connecting plate 24 will push the clamping plate 25 to move together. Since the rotating disc 502 only rotates 180°, the symmetrical clamping grooves 30 on the rotating disc 502 will be replaced in position. Thus, the movement of the connecting plate 24 pushing the clamping plate 25 will make the clamping plate 25 enter the clamping groove 30 of the rotating disc 502, so that the rotating disc 502 will be limited in position.

[0082] Because the length of the clamping block 404 is set, only after the supporting block 703 resets to push the limiting plate 702 and the supporting plate 701, it will be completely separated from the steel structure 3, avoiding the steel structure 3 from being separated too early and not being supported.

[0083] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, combinations, and alterations can be made to the embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
