Description

Technical Field

[0001] This utility model relates to the technical field of steel structure processing equipment, specifically a large steel structure anti-tipping and overturning frame. Background Technology

[0002] Large steel structural components are widely used in construction, bridges, and machinery manufacturing. Their processing requires flipping operations to achieve welding, assembly, and inspection of different surfaces. Due to the large size, heavy weight, and complex structure of steel structural components, manual flipping is not only labor-intensive and inefficient but also poses a high safety risk. Traditional methods relying on lifting equipment for flipping are prone to positioning deviations and unstable flipping, seriously affecting processing quality and production progress. Therefore, there is an urgent need for a dedicated anti-tipping automatic flipping device to meet production requirements.

[0003] A search revealed Chinese patent publication number CN222857172U, "An Automatic Tilting Device for Steel Arch Frame Processing," which discloses a structure based on hydraulic cylinder lifting and a motor-driven arc-shaped rack plate to rotate the arc plate. While this improves upon some of the shortcomings of traditional electric hoists, it still has significant deficiencies. The device is designed only for a single steel arch frame and does not have multiple independent positioning and clamping units. It cannot simultaneously position and fix multiple key parts of multiple small or large steel structural components. When operating multiple batches or multiple components, the positioning, clamping, and rotating processes must be repeated for each group. It lacks a linkage design for the synchronous rotation of multiple workpieces and cannot meet the requirements for efficient and high-precision multi-component rotation processing. Therefore, a large steel structural component anti-tipping rotation frame is provided to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a large steel structure anti-tipping and overturning frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large steel structure anti-tipping and overturning frame, comprising: A tilting frame support mechanism includes a main support frame, and two sets of the main support frames are provided. A set of motor support frames is fixedly connected to one side of the main support frames that is far apart from each other. A steel structure component fixing mechanism is provided, wherein two sets of the steel structure component fixing mechanism are provided, and the steel structure component fixing mechanism is provided between the two sets of main support frames. The steel structure component fixing mechanism is used to fix the steel structure component to be flipped. A flipping synchronous drive mechanism is provided on the outside of the main support frame. The flipping synchronous drive mechanism is used to synchronously drive the two sets of steel structure fixing mechanisms to flip synchronously.

[0006] As a further embodiment of this utility model: the steel structure fixing mechanism includes a structural component fixing frame, the structural component fixing frame having several sets of positioning slots symmetrically opened on both sides, a set of central rotating shafts symmetrically fixedly connected to both sides of the structural component fixing frame near the main support frame, side connecting shafts symmetrically fixedly connected to both sides of the structural component fixing frame, and two sets of upper fixing blocks symmetrically fixedly connected to both sides of each set of positioning slots above the structural component fixing frame, an electric telescopic rod embedded in the inner side of the upper fixing block, and a clamping plate fixedly connected to the movable end of the electric telescopic rod.

[0008] As a further improvement of this utility model, the central pivots at both ends of each set of structural component fixing frames are rotatably connected to the inner side of a set of main support frames at corresponding positions.

[0009] As a further improvement of this utility model: the number of drive motors is set to two sets, and each set of drive motors is fixedly connected above a set of motor support frames.

[0010] As a further embodiment of this utility model: one side of the synchronous connecting plate is rotatably connected to the right-angle connecting arm, and the two ends of the other side of the synchronous connecting plate are respectively rotatably connected to a set of side connecting shafts.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1.

Each set of positioning slots is equipped with an independent upper fixing block, an electric telescopic rod, and a clamping plate, which can simultaneously and accurately position and clamp multiple key parts of multiple small steel structural components or large steel structural components. With the synchronous drive mechanism for flipping, the synchronous drive of the two sets of steel structural component fixing mechanisms can realize the synchronous flipping operation of multiple sets of workpieces. There is no need to perform positioning, fixing and flipping operations for each set, which greatly improves the flexibility of flipping operations of multiple batches or multiple parts of steel structural components, significantly reduces the overall operation time, and further optimizes the efficiency of the production process. 2. In this utility model, the steel structure components are automatically clamped and fixed by an electric telescopic rod, and synchronously rotated by a drive motor.

The embodiments of this utility model will be described below based on its overall structure.

[0016] Reference Figures 1 to 5 In this embodiment of the utility model, the anti-tipping and overturning frame for large steel structures includes: The tilting frame support mechanism 1 includes a main support frame 11. There are two sets of main support frames 11. A set of motor support frames 12 is fixedly connected to the side of the main support frames 11 that is far apart from each other. The steel structure component fixing mechanism 2 is provided in two sets. The steel structure component fixing mechanism 2 is located between the two sets of main support frames 11. The steel structure component fixing mechanism 2 is used to fix the steel structure component to be flipped. The flipping synchronous drive mechanism 3 is located on the outside of the main support frame 11. The flipping synchronous drive mechanism 3 is used to synchronously drive the two sets of steel structure fixing mechanisms 2 to flip synchronously.

[0017] The above scheme is adopted: the main support frame 11 provides basic support for the entire tilting frame, and the two sets of main support frames 11 together provide a support foundation for the installation and rotation of the steel structure fixing mechanism 2; the motor support frame 12 is used to install and fix the tilting synchronous drive mechanism 3 to ensure its stable operation; the steel structure fixing mechanism 2 can fix the steel structure to be tilted to prevent it from shifting during the tilting process; the tilting synchronous drive mechanism 3 synchronously drives the two sets of steel structure fixing mechanisms 2 to ensure that the tilting action of the two is consistent and to prevent the steel structure from overturning due to the asynchronous tilting of the two sets of fixing mechanisms on both sides.

[0018] The steel structure component fixing mechanism 2 includes a structural component fixing frame 21. Several sets of positioning slots 22 are symmetrically opened on both sides of the structural component fixing frame 21. A set of central rotating shafts 23 are symmetrically fixedly connected to both sides of the structural component fixing frame 21 near the main support frame 11. The central rotating shafts 23 at both ends of each set of structural component fixing frames 21 are rotatably connected to the inner side of a set of main support frames 11 at the corresponding position. Side connecting shafts 24 are symmetrically fixedly connected to both sides of the structural component fixing frame 21. Two sets of upper fixing blocks 25 are symmetrically fixedly connected to the upper fixing frame 21 on both sides of each set of positioning slots 22. An electric telescopic rod 26 is embedded in the inner side of the upper fixing block 25. A clamping plate 27 is fixedly connected to the movable end of the electric telescopic rod 26.

[0019] The above scheme is adopted as follows: the structural component fixing frame 21 serves as the main structure supporting the steel structural component to be flipped. The positioning slot 22 can initially position the edge or specific part of the steel structural component to assist in its accurate placement. The central rotating shaft 23 is rotatably connected to the inner side of the main support frame 11, so that the structural component fixing frame 21 can rotate around the central rotating shaft 23 as the fulcrum, providing a rotational basis for the flipping of the steel structural component. The side connecting shaft 24 is used to connect with the flipping synchronous drive mechanism 3 to receive the driving force to drive the structural component fixing frame 21 to rotate. The upper fixing block 25 provides an installation carrier for the electric telescopic rod 26. When the electric telescopic rod 26 extends and retracts, it drives the clamping plate 27 to move. By bringing the two sets of clamping plates 27 on both sides of the positioning slot 22 closer to each other, the steel structural component placed on the structural component fixing frame 21 can be clamped and fixed to prevent the steel structural component from loosening or falling off during the flipping process.

[0020] The flipping synchronous drive mechanism 3 includes a drive motor 31. There are two sets of drive motors 31. Each set of drive motors 31 is fixedly connected above a set of motor support frames 12. The movable end of the drive motor 31 is fixedly connected to a connecting shaft 32. One section of the connecting shaft 32 passes through the main support frame 11 and is fixedly connected to a right-angle connecting arm 33. The other end of the right-angle connecting arm 33 is rotatably connected to a synchronous connecting plate 34. One side of the synchronous connecting plate 34 is rotatably connected to the right-angle connecting arm 33, and the two ends of the other side of the synchronous connecting plate 34 are rotatably connected to a set of side connecting shafts 24.

[0021] The above scheme is adopted: the drive motor 31 is fixed on the motor support frame 12 as a power source. When its movable end rotates, it drives the connecting shaft 32 to rotate synchronously. The connecting shaft 32 transmits the driving force to the right-angle connecting arm 33, so that the right-angle connecting arm 33 rotates around the axis of the connecting shaft 32. When the right-angle connecting arm 33 rotates, it pushes or pulls the synchronous connecting plate 34. Since the synchronous connecting plate 34 is rotatably connected to the two sets of side connecting shafts 24 respectively, it can transmit the driving force synchronously to the two sets of structural component fixing frames 21, so as to drive the two sets of steel structural component fixing mechanisms 2 to rotate synchronously with their respective central rotating shafts 23 as fulcrums, ensuring that the two sets of fixing mechanisms move in unison during the rotation process, and avoiding the steel structural components from overturning due to uneven force.

[0022] The working principle of this utility model is as follows: At the start of the operation, the steel structure to be flipped is placed on the structural component fixing frame 21 of the two sets of steel structure fixing mechanisms 2. The positioning slots 22 on both sides of the structural component fixing frame 21 are used to initially position the edge or specific part of the steel structure to ensure that the steel structure is placed accurately. Then, the electric telescopic rod 26 embedded in the inner side of the upper fixing block 25 is activated. The movable end of the electric telescopic rod 26 drives the clamping plate 27 to move towards the steel structure. The two sets of clamping plates 27 on both sides of each set of positioning slots 22 approach each other and fit tightly against the surface of the steel structure to firmly clamp and fix the steel structure, so as to avoid loosening, falling off or displacement during the subsequent flipping process. After the steel structure is fixed, the two sets of drive motors 31 in the flipping synchronous drive mechanism 3 are started. The two sets of drive motors 31 are fixed on the motor support frame 12 on the outside of the main support frame 11. When working, the movable end of the drive motor 31 rotates synchronously and drives the connecting shaft 32 to rotate together. After the connecting shaft 32 passes through the main support frame 11, it transmits the driving force to the right-angle connecting arm 33 fixedly connected at its end, so that the right-angle connecting arm 33 swings synchronously around the axis of the connecting shaft 32. When the right-angle connecting arm 33 swings, it will simultaneously push or pull the synchronous connecting plate 34 that is rotatably connected to it. Since the other two ends of the synchronous connecting plate 34 are rotatably connected to the side connecting shafts 24 of the two sets of steel structure fixing mechanisms 2, the driving force is transmitted evenly and synchronously to the two sets of structural component fixing frames 21 through the synchronous connecting plate 34. At this time, the structural component fixing frames 21 rotate inside the main support frame 11 through the central rotating shafts 23 on both sides. The two sets of structural component fixing frames 21 achieve synchronous flipping with their respective central rotating shafts 23 as fulcrums, ensuring that the steel structure is subjected to balanced force on both sides and the flipping action is consistent, effectively preventing the overturning problem caused by asynchronous flipping on both sides. After flipping to the target angle, the drive motor 31 is turned off to complete the flipping operation of the steel structure.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
