Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, specifically a flipping device for steel structure processing. Background Technology

[0002] In the field of steel structure processing, it is often necessary to flip over large and heavy steel sections. Taking building steel structures as an example, during welding or painting, the steel sections usually need to be flipped multiple times to complete processing operations on different sides. To meet this requirement, a flipping device with publication number CN105665895B uses multiple rotating wheels in conjunction with a roller assembly. A drive mechanism makes the rotating wheels rotate synchronously to achieve the flipping action of the steel sections. This structure can meet the flipping requirements of large and heavy steel sections and improves processing efficiency to a certain extent.

[0003] However, this design relies on precise synchronous control of multiple rotating wheels. If any one of these wheels fails, the entire flipping process may fail, affecting the stability and reliability of the flipping. Furthermore, this design has high requirements for the foundation, increasing installation and maintenance costs. Therefore, there is a need in the art for a more stable and cost-effective flipping device technology. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figs. 1 to 4 As shown, this embodiment provides a flipping device for steel structure processing, comprising: a base frame 1, the base frame 1 including feet 11, which are disposed at the bottom of a base plate 12 for supporting the steel structure; a base plate 12, which is disposed above the feet 11; guide rails 13, which are symmetrically disposed above the base plate 12; a sliding plate 14, which is disposed above the guide rails 13 and slidably connected to the guide rails 13; a lead screw 15, which is disposed above the base plate 12, one end of which is connected to the base frame 1 via a bearing, and the other end is connected to the output end of a first motor 16 and threadedly connected to the sliding plate 14; a support assembly 2 is provided on the base frame 1, and a clamping and flipping assembly 3 is rotatably connected to the support assembly 2 for clamping the H-beam; a flipping drive mechanism 4 is provided above the base frame 1, and the flipping drive mechanism 4 is rotatably connected to the clamping and flipping assembly 3 for driving the clamping and flipping assembly 3 to flip the H-beam.

[0030] In this embodiment, the second motor 41 in the flipping drive mechanism 4 starts, and after being reduced in speed and torque by the reducer 42, it drives the transmission rod 43 to rotate. The transmission rod drives the gripper cylinder 31, the arc-shaped clamping arm 32, etc., to rotate together, thereby realizing the flipping of the H-beam. Specifically, the base frame 1 also includes: a limiting plate 17, which is set at both ends of the guide rail 13 to limit the sliding plate 14 from going beyond the range of the guide rail 13 during movement; and a shock-absorbing pad 18, which is set at the bottom of the base plate 12 to reduce the vibration generated when the workpiece is flipped.

[0031] In this embodiment, the limiting plate 17 prevents the sliding plate 14 from exceeding its stroke, and the shock-absorbing pad 18 absorbs the vibration of the workpiece flipping, preventing the sliding plate 14 from disengaging from the guide rail 13 and reducing the vibration of the equipment operation.

[0032] Specifically, bolts are provided at the two corners of the base 11, and the levelness of the base frame 1 can be adjusted by rotating the bolts.

[0033] As a preferred implementation, bolts are provided at two opposite corners of the foot 11. The bolts are M16 and made of 35# steel. The height of the foot 11 can be adjusted by rotating the bolts to achieve the levelness adjustment of the base frame 1, ensuring that the equipment is installed stably.

[0034] Example 2:

[0035] Based on Example 1, a support component was added to provide a stable foundation for the clamping and reversing component.

[0036] Specifically, the support assembly 2 includes: a flange 21, which is fixedly connected to the flipping drive mechanism 4 and is used to provide stable support for clamping and flipping assembly 3; a bracket 23, which is fixedly connected above the base frame 1 and has a torque sensor 22 installed on it; and a control panel 24, which is fixedly installed above the sliding plate 14.

[0037] It should be noted that bracket 23 supports torque sensor 22, flange 21 provides support for clamping and tilting assembly 3, and control panel 24 receives and processes signals to ensure stable support of clamping and tilting assembly 3. This enables the reception, processing, and control of data from torque sensor 22, pressure sensor 33, etc., providing data support and a control basis for equipment operation. The torque sensor can be selected as model KR-803, and the pressure sensor can be selected as model STW06.

[0038] Specifically, the clamping and flipping assembly 3 includes: a clamping support 34, which is rotatably connected to the transmission rod 43; a gripper cylinder 31, which is disposed inside the clamping support 34 and has an arc-shaped clamping arm 32 hinged to its output end, which drives the arc-shaped clamping arm 32 to clamp the workpiece through telescopic movement; and a pressure sensor 33, which is disposed on the inner wall of the arc-shaped clamping arm 32, for monitoring the magnitude of the pressure applied during the clamping process.

[0039] As a preferred implementation, the gripper cylinder 31 extends and retracts to drive the arc-shaped clamping arm 32 to open and close to clamp the workpiece, and the pressure sensor 33 monitors the clamping pressure to achieve stable clamping of the H-beam and monitor the clamping pressure in real time.

[0040] Specifically, there are two sets of symmetrically arranged arc-shaped clamping arms 32.

[0041] It should be noted that each set of arc-shaped clamping arms is driven by a gripper cylinder to stably clamp the H-beam from both sides. The two sets of symmetrical arc-shaped clamping walls move synchronously under the action of the gripper cylinder to clamp the H-beam, thereby enhancing the clamping stability and reliability of the H-beam.

[0042] Specifically, the flipping drive mechanism 4 includes: a second motor 41, which is disposed above the base plate 12; and a transmission rod 43, which is connected to the second motor 41 through a reducer 42, and the other end is connected to a torque sensor 22 for detecting the rotation angle.

[0043] In this embodiment, the second motor 41 drives the transmission rod 43 to rotate after being reduced in speed and increased in torque by the reducer 42, thereby driving the clamping and flipping assembly 3 to flip, providing stable power for the flipping of the H-beam and achieving precise control of the flipping angle.

[0044] In operation, the operator first activates the first motor 16 to drive the lead screw 15, adjusting the sliding plate 14 along the guide rail 13 to a suitable position to accommodate the length of the H-beam. Simultaneously, the limiting plate 17 prevents the sliding plate 14 from exceeding the range of the guide rail 13 during movement. After the H-beam is hoisted onto the clamping and flipping assembly 3, the gripper cylinder 31 is activated. The gripper cylinder 31 drives the arc-shaped clamping arm 32 to clamp the H-beam through its telescopic movement. Simultaneously, the pressure sensor 33 on the inner wall of the arc-shaped clamping arm 32 monitors the pressure during clamping in real time and transmits the data to the control panel 24, allowing the operator to adjust the clamping force as needed. After activating the second motor 41, the second motor 41 transmits torque to the transmission rod 43 via the reducer 42. The transmission rod 43 then transmits the torque to the clamping and flipping assembly 3, thus achieving the flipping operation of the H-beam. During this process, the torque sensor 22 monitors the applied torque in real time and feeds the signal back to the control panel 24. The control panel 24 automatically adjusts the operating status of the second motor 41 based on the feedback signal from the torque sensor 22 to achieve precise control of the flipping process. Additionally, multiple sets of feet 11 under the base plate 12 can be adjusted to raise or lower the device to a suitable position. The shock-absorbing pads 18 at the bottom of the base plate 12 reduce vibrations generated during the flipping process.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
