Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a 360° flipping device for opening and closing steel structure components. Background Technology

[0002] Welding of steel structural components involves four positions: flat welding, horizontal welding, vertical welding, and overhead welding. In large-scale welding processes, flat welding and horizontal welding are mostly used. To achieve flat welding and horizontal welding, an openable structure is generally adopted to facilitate the one-time hoisting and positioning of the components. At the same time, the components are rotated four times at 90°, 180°, 270°, and 360° using a rotating device.

[0003] In the prior art, such as the patent with publication number CN222831609U, a steel structure flipping device is disclosed, including a support base. The support base has placement through holes on both sides, and a connecting hole is opened on the outside of the placement through holes. Rotating rings are connected to both sides inside the support base. Two crossbars are connected between the two rotating rings. A connecting ring is connected to the inside of the connecting hole. A driving assembly is installed between the support base and the connecting ring. A clamping assembly for fixing the workpiece is installed inside the rotating ring.

[0004] The above structure drives the connecting ring to rotate through the teeth on the outside of the connecting ring. However, when four specified flips of 90°, 180°, 270° and 360° are required, the transition flips between different orientations are slow, resulting in low process efficiency. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an openable steel structure component 360° flipping device to solve the problem of slow transition flipping between different orientations and low process efficiency when four specified flips of 90°, 180°, 270° and 360° are required.

[0006] Based on the above objectives, this utility model provides a 360° rotating device for opening and closing steel structure components, including a platform, on which a fixed frame and a slide rail are fixedly installed, and multiple sets of movable frames are slidably installed on the slide rail. A main frame is rotatably installed on the fixed frame, and a secondary frame is rotatably installed on the movable frame.

[0007] The sub-frame has a hollow groove inside, and the main frame has a slot on one side. Both the hollow groove and the slot are provided with multiple sets of clamping structures. Multiple sets of connecting rods are fixedly installed between the sub-frame and the main frame.

[0008] A drive component is provided on one side of the main frame, which is used to drive the sub-frame and the main frame to rotate.

[0009] Preferably, the driving component includes a bearing seat fixedly mounted on a fixed frame, a turntable rotatably mounted on one side of the bearing seat, a geared motor fixedly mounted on the other side of the bearing seat, the output end of the geared motor connected to the turntable, a pin fixedly mounted on the outside of the turntable, and a guide post fixedly mounted on the pin.

[0010] A bearing rod is also fixedly installed on the fixed frame. A grooved wheel is rotatably installed at one end of the bearing rod. The grooved wheel is fixedly connected to the main frame. Both the grooved wheel and the turntable have arc-shaped grooves on their outer sides. Multiple sets of guide grooves corresponding to the guide columns are distributed around the inside of the grooved wheel.

[0011] Preferably, the clamping structure includes multiple sets of hydraulic cylinders fixedly installed inside the hollow groove and the slot, and the output ends of the multiple sets of hydraulic cylinders are all fixedly connected with rubber pads.

[0012] Preferably, a secondary rod is fixedly installed on the bearing rod, and a magnetic suction head is slidably installed inside the secondary rod, with the magnetic suction head corresponding to the turntable.

[0013] Preferably, the sub-frame is provided with at least two sets, and the connecting rod is provided with at least four sets, with the connecting rods being equidistantly distributed on the outside of the main frame.

[0014] Preferably, the sub-frame has multiple sets of adsorption heads distributed at equal intervals inside, and the movable frame has iron blocks corresponding to the adsorption heads distributed in a mirror image inside.

[0015] Preferably, a groove is provided on the other side of the main frame, an active rod is fixedly installed on the bearing seat, and a roller is movably installed at the top of the active rod, with the roller fitting into the groove.

[0016] The beneficial effects of this utility model are:

[0017] The steel structure component that needs to be flipped is placed in the hollow groove within multiple sets of sub-frames. The spacing between the multiple sets of sub-frames is adjusted. Then, the end of the steel structure component is installed in the slot within the main frame and clamped by the slot and the clamping structure within the hollow groove.

[0018] After the steel structure components are clamped, the driving component causes the main frame to rotate 90°, 180°, 270° and 360° in sequence. Under the action of the connecting rod, the main frame drives the sub-frame to rotate and flip simultaneously, thus enabling direct flipping in four directions. This solves the problem of slow transition flipping between different directions, and meets the requirements of flat welding and horizontal welding of welds in different parts. The flipping process is stable and the process efficiency is high. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a 360° rotating device for opening and closing steel structure components includes a platform 3, a fixed frame 1 and a slide rail 29 fixedly installed on the platform 3, multiple sets of movable frames 2 slidably installed on the slide rail 29, a main frame 5 rotatably installed on the fixed frame 1, and a secondary frame 4 rotatably installed on the movable frames 2.

[0027] The sub-frame 4 has a hollow groove 7 inside, and the main frame 5 has a slot 10 on one side. Both the hollow groove 7 and the slot 10 have multiple sets of clamping structures 8 inside. Multiple sets of connecting rods 6 are fixedly installed between the sub-frame 4 and the main frame 5.

[0028] A drive component 9 is provided on one side of the main frame 5. The drive component 9 is used to drive the sub-frame 4 and the main frame 5 to rotate.

[0029] In this embodiment, the steel structure component that needs to be flipped is placed in the hollow groove 7 within multiple sets of sub-frames 4, the spacing between the multiple sets of sub-frames 4 is adjusted, and then the end of the steel structure component is installed in the slot 10 within the main frame 5, and clamped by the slot 10 and the clamping structure 8 within the hollow groove 7.

[0030] After the steel structure components are clamped, the driving component 9 causes the main frame 5 to rotate 90°, 180°, 270° and 360° in sequence. Under the action of the connecting rod 6, the main frame 5 drives the secondary frame 4 to rotate and flip at the same time, so that it can directly flip in four directions, solving the problem of slow transition flipping between different directions.

[0031] As one implementation method, such as Figure 2 and Figure 3 As shown, the drive unit 9 includes a bearing seat 14 fixedly mounted on the fixed frame 1. A turntable 16 is rotatably mounted on one side of the bearing seat 14, and a geared motor 15 is fixedly mounted on the other side of the bearing seat 14. The output end of the geared motor 15 is connected to the turntable 16. A pin 17 is fixedly mounted on the outside of the turntable 16, and a guide post 18 is fixedly mounted on the pin 17.

[0032] A bearing rod 22 is also fixedly installed on the fixed frame 1. A grooved wheel 19 is rotatably installed at one end of the bearing rod 22. The grooved wheel 19 is fixedly connected to the main frame 5. Both the grooved wheel 19 and the turntable 16 have arc-shaped grooves 21 on their exteriors. Multiple sets of guide grooves 20 corresponding to the guide posts 18 are distributed around the inside of the grooved wheel 19.

[0033] In this embodiment, the turntable 16 is driven to rotate by the geared motor 15 inside the drive component 9. When the turntable 16 rotates, it fits against the arc groove 21 outside the grooved wheel 19. When the pin 17 on the turntable 16 rotates, the guide post 18 inserts into the guide groove 20 inside the grooved wheel 19, causing the grooved wheel 19 to rotate intermittently, so that the main frame 5 rotates 90°, 180°, 270° and 360° in sequence. Under the action of the connecting rod 6, the main frame 5 drives the sub-frame 4 to rotate and flip at the same time.

[0034] As one implementation method, such as Figure 4 As shown, the clamping structure 8 includes multiple sets of hydraulic cylinders 27 fixedly installed inside the hollow groove 7 and the slot 10, and the output ends of the multiple sets of hydraulic cylinders 27 are all fixedly connected with rubber pads 28.

[0035] In this embodiment, the end of the steel structure component is installed in the slot 10 inside the main frame 5, and is clamped by the slot 10 and the clamping structure 8 inside the hollow slot 7. The component is clamped by four hydraulic cylinders 27 in the upper, lower, left and right sides in the clamping structure 8, thereby improving the stable clamping effect of the steel structure component.

[0036] As one implementation method, such as Figure 2 and Figure 3 As shown, a secondary rod 23 is fixedly installed on the bearing rod 22, and a magnetic head 24 is slidably installed inside the secondary rod 23. The magnetic head 24 corresponds to the turntable 16.

[0037] In this embodiment, when the sub-frame 4 and the main frame 5 rotate to 90°, 180°, 270° and 360° respectively, and the turntable 16 stops rotating, the magnetic suction head 24 on the sub-rod 23 restricts the turntable 16, thereby improving the stability of the processing after flipping to the specified angle and preventing the sub-frame 4 and the main frame 5 from shaking.

[0038] As one implementation method, such as Figure 4 As shown, the sub-frame 4 is provided with at least two sets, and the connecting rods 6 are provided with at least four sets, and the connecting rods 6 are equidistantly distributed on the outside of the main frame 5.

[0039] The sub-frame 4 has multiple sets of adsorption heads 25 distributed at equal intervals inside, and the movable frame 2 has iron blocks 26 corresponding to the adsorption heads 25 distributed in a mirror image inside.

[0040] In this embodiment, when the multiple sets of sub-frames 4 rotate within the movable frame 2, the multiple sets of adsorption heads 25 provided within the sub-frames 4 adsorb each other and limit the movement when they rotate to 90°, 180°, 270° and 360° angles respectively, thus preventing insufficient clamping stability when processing steel structure components after flipping to the specified angle.

[0041] As one implementation method, such as Figure 1 , Figure 2 As shown, a groove 11 is provided on the other side of the main frame 5, and an active rod 12 is fixedly installed on the bearing seat 14. A roller 13 is movably installed on the top of the active rod 12, and the roller 13 fits into the groove 11.

[0042] In this embodiment, the main frame 5 rotates sequentially by 90°, 180°, 270° and 360°. Under the action of the connecting rod 6, the main frame 5 drives the sub-frame 4 to rotate and flip simultaneously. During the flipping, the groove 11 on one side of the main frame 5 is attached to the roller 13 by the active rod 12, which maintains the smooth rotation of the main frame 5 and the sub-frame 4.

[0043] Working principle: When in use, first place the steel structure component to be flipped in the hollow groove 7 in the multiple sets of sub-frames 4, adjust the spacing between the multiple sets of sub-frames 4, and then install the end of the steel structure component in the slot 10 in the main frame 5. It is clamped by the slot 10 and the clamping structure 8 in the hollow groove 7. The component is clamped by four hydraulic cylinders 27 in the clamping structure 8.

[0044] After the steel structure components are clamped, the turntable 16 is driven to rotate by the geared motor 15 inside the drive component 9. When the turntable 16 rotates, it fits against the arc groove 21 outside the grooved wheel 19. When the pin 17 on the turntable 16 rotates, the guide post 18 inserts into the guide slide groove 20 inside the grooved wheel 19, and drives the grooved wheel 19 to rotate intermittently, so that the main frame 5 rotates 90°, 180°, 270° and 360° in sequence. Under the action of the connecting rod 6, the main frame 5 drives the secondary frame 4 to rotate and flip at the same time.

[0045] During the rotation process, when the multiple sets of sub-frames 4 rotate within the movable frame 2, the multiple sets of adsorption heads 25 installed within the sub-frames 4 adsorb each other with the iron blocks 26 within the movable frame 2 when they rotate to angles of 90°, 180°, 270° and 360° respectively, thus limiting their position. At the same time, when the turntable 16 stops rotating, the magnetic adsorption head 24 on the sub-rod 23 restricts the turntable 16.

[0046] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
