Description

An easy-to-operate rapid positioning device for steel structures Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a quick positioning device for steel structures that is easy to operate. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. Welding is an important connection method for steel structures. A Chinese utility model patent, authorized publication number "CN222200315U," discloses a positioning device for steel structure processing, including a processing plate. A main adjustment box is fixedly connected to the bottom surface of the processing plate. A drive motor is fixedly installed on the right side of the main adjustment box via a square frame. The output end of the drive motor passes through the main adjustment box and is fixedly connected to a threaded rod. A square sliding plate is threadedly connected to the outer surface of the threaded rod.

[0003] The above technical solution utilizes the operation of a drive motor to rotate a threaded screw, which can move the movable support plate and the fixed frame left and right, achieving the effect of adjusting the position of the movable support plate. However, the above technical solution still has certain defects. When fixing and positioning the steel structure being processed, the steel structure usually has a long length. That is, the movable support plate, the clamping plate, the support plate, and the clamping strip fix and position two steel structures respectively. The long steel structure has a certain weight. When fixing the steel structure, the steel structures at both ends of the device will bend downward under the action of their own weight. During the bending process, it will put a burden on the device and easily cause deformation of the steel structure at the processing point, affecting the processing quality. Therefore, this utility model proposes a new solution. Summary of the Invention

[0035] Please refer to Figures 1-6. This utility model provides a technical solution: a quick positioning device for easy-to-operate steel structures, including a steel structure processing table 1. The surface of the steel structure processing table 1 is provided with a first sliding groove 2 and two second sliding grooves 3. A movable block 7 is slidably connected to the inner wall of the first sliding groove 2. A steel structure limiting component is set on the steel structure processing table 1. A steel structure support component is set on the steel structure processing table 1. The steel structure support component includes a connecting plate 8, which is fixedly connected to the right side of the movable block 7. The connecting plate 8 is "T" shaped. A first hydraulic rod 9 is fixedly connected inside the connecting plate 8. A fixed frame 10 is fixedly connected to the output end of the first hydraulic rod 9. Two second guide rods 11 are fixedly connected to the lower end of the fixed frame 10. Both second guide rods 11 are slidably connected to the connecting plate 8. A steel structure support roller shaft 12 is rotatably connected to the inner side of the fixed frame 10. Multiple first rollers 13 are rotatably connected to the surface of the steel structure support roller shaft 12.

[0036] The steel structure limiting assembly includes a second fixed frame 15, which is fixedly connected to the movable block 7. A rotating shaft 16 is rotatably connected inside the second fixed frame 15. The rotating shaft 16 is cylindrical, and a gear ring 17 is fixedly connected to the surface of the rotating shaft 16. A second drive motor 18 is fixedly connected to the upper end of the second fixed frame 15. A gear 19 is fixedly connected to the output end of the second drive motor 18, and the gear 19 meshes with the gear ring 17. A connecting bracket 20 is fixedly connected to the upper end of the rotating shaft 16. A second hydraulic rod 21 is fixedly connected inside the connecting bracket 20 and extends into the interior of the rotating shaft 16. A steel structure limiting plate 22 is fixedly connected to the output end of the second hydraulic rod 21. The steel structure limiting plate 22 is arc-shaped. There are two sets of the connecting bracket 20, the second hydraulic rod 21, and the steel structure limiting plate 22, which are symmetrically arranged on the upper and lower sides of the rotating shaft 16.

[0037] The number of the first hydraulic rod 9, the fixed frame 10, the second guide rod 11, the steel structure support roller shaft 12, and the first roller 13 are all four sets, which are symmetrically arranged on the corresponding connecting plate 8 and on the left and right sides of the steel structure processing table 1.

[0038] There are two movable blocks 7 and two connecting plates 8, which are symmetrically arranged on the surface of the corresponding movable blocks 7.

[0039] There are two sets of steel structure limiting components, which are symmetrically arranged on the corresponding movable blocks 7.

[0040] A first drive motor 4 is fixedly connected to the right side of the steel structure processing table 1. A bidirectional threaded rod 5 is fixedly connected to the output end of the first drive motor 4. The bidirectional threaded rod 5 is rotatably connected to the steel structure processing table 1. A first guide rod 6 is fixedly connected to the inner wall of each of the two second slide grooves 3. Two movable blocks 7 are respectively symmetrically threaded onto the surface of the bidirectional threaded rod 5. Both movable blocks 7 are slidably connected to the two first guide rods 6 and to the two second slide grooves 3.

[0041] The upper end of the steel structure processing table 1 is rotatably connected to multiple second rollers 14, which are divided into two groups and symmetrically arranged on the upper end of the steel structure processing table 1.

[0042] When using this device, the first drive motor 4 is started, and its output end drives the bidirectional threaded rod 5 to rotate. Since the two movable blocks 7 are respectively symmetrically threaded onto the bidirectional threaded rod 5 and slidably connected to the first guide rod 6 and sliding in the second slide groove 3, the rotation of the bidirectional threaded rod 5 drives the two movable blocks 7 to move relative to or away from each other along the first guide rod 6 and the second slide groove 3. During this process, the multiple second rollers 14 rotatably connected to the upper end of the steel structure processing table 1 play an important role. The second rollers 14 are divided into two groups of symmetrical arrangement, which provide support for the movable blocks 7 when they move, reduce the friction between the movable blocks 7 and the processing table, and make the movement smoother. At the same time, the second rollers 14 also play a guiding role, ensuring that the movable blocks 7 move along the predetermined track, ensuring the movement accuracy, and then accurately adjusting the distance between the two movable blocks 7 according to the length of the cylindrical steel structure, laying the foundation for subsequent support and limit operations.

[0043] When the movable block 7 moves to the appropriate position, the first hydraulic rod 9 is activated. The first hydraulic rod 9 is installed inside the connecting plate 8, and its output end pushes the fixed frame 10 upward. The second guide rod 11 at the lower end of the fixed frame 10 is slidably connected to the connecting plate 8 to ensure the stable lifting and lowering of the fixed frame 10. As the fixed frame 10 rises, the steel structure support roller 12 and the first roller 13 on its surface gradually approach and contact the cylindrical steel structure. The four sets of steel structure support rollers 12 are evenly distributed on the left and right sides of the steel structure processing table 1, and the support components work together to effectively share the weight of the steel structure and avoid bending deformation caused by its own weight. At the same time, when using the steel structure support roller 12 to support the steel structure, the second roller 14 provides auxiliary support to the connecting plate 8, reducing the degree of deformation of the connecting plate 8 and improving the stability during the support process.

[0044] The second hydraulic rod 21 is activated, pushing the arc-shaped steel structure limiting plate 22 closer to the steel structure; the two sets of limiting plates approach the steel structure from both above and below, tightly limiting the steel structure in the middle; the arc-shaped steel structure limiting plate 22 can better fit the shape of the cylindrical steel structure, providing a stable and reliable limiting effect, not only achieving precise positioning of the steel structure, but also effectively preventing displacement of the steel structure during processing, ensuring processing accuracy.

[0045] The second drive motor 18 is started, and the gear 19 at its output end meshes with the gear ring 17 on the rotating shaft 16, driving the rotating shaft 16 to rotate inside the second fixed frame 15. When the rotating shaft 16 rotates, the connecting bracket 20 rotates accordingly, and the second hydraulic rod 21 inside the connecting bracket 20 also rotates. When it is necessary to adjust the angle of the steel structure, the rotating shaft 16 is first rotated by the second drive motor 18 to rotate the connecting bracket 20 to a suitable angle. Since the connecting bracket 20, the second hydraulic rod 21 and the steel structure limiting plate 22 are all symmetrically arranged on the upper and lower sides of the rotating shaft 16, the steel structure support roller shaft 12 is always maintained to support the cylindrical steel structure during the angle adjustment process, ensuring that the steel structure will not lose support due to angle adjustment and fall or deform.

[0046] When adjusting the angle of the steel structure, the first roller 13 and the steel structure support roller 12 continue to play a key role. The first roller 13 can rotate freely on the steel structure support roller 12. During the rotation of the steel structure, the first roller 13 assists in supporting the steel structure, reduces the friction between the steel structure and the steel structure support roller 12, and at the same time plays a guiding role, ensuring that the steel structure remains stable during rotation and always provides a reliable support foundation for the cylindrical steel structure.

[0047] Furthermore, by moving the movable block 7 and by using the second roller 14 to provide auxiliary support and guidance during the movement of the movable block 7 and the connecting plate 8, the moving accuracy of the movable block 7 is ensured, thereby achieving precise adjustment of the position of the movable block 7. This lays a solid foundation for the subsequent precise support and limiting of the steel structure. The steel structure is also supported by multiple steel structure support rollers 12 and the first roller 13, which share the weight of the steel structure and effectively prevent bending deformation caused by the weight of the steel structure, thus ensuring the stability of the steel structure during processing.

[0048] Furthermore, the setting of the rotating shaft 16 and the steel structure limiting plate 22 facilitates the rapid positioning of the steel structure, effectively prevents displacement of the steel structure, ensures processing accuracy, and allows the steel structure to rotate around the rotating shaft 16 during the positioning process, making it easy to adjust the angle of the steel structure and facilitate the processing of the steel structure, thereby improving the practicality and convenience of the device and increasing processing efficiency.

[0049] The first drive motor 4 and the bidirectional threaded rod 5 facilitate the adjustment of the positions of the movable block 7 and the connecting plate 8. During the support process, the second roller 14 also provides auxiliary support to the connecting plate 8, enhancing stability. The entire support operation can be completed by activating the first hydraulic rod 9, which is simple to operate and provides reliable support. During the adjustment process, the steel structure support roller 12 and the first roller 13 continuously support the steel structure. The first roller 13 reduces friction and guides the steel structure, ensuring stable rotation. The operator can easily adjust the angle of the steel structure by controlling the second drive motor 18, which facilitates processing the steel structure at different angles and improves the practicality and processing efficiency of the device.

[0050] Structural Description: Steel Structure Processing Table 1: As the basic support structure of the entire device, the first slide groove 2 and the second slide groove 3 opened on its surface provide tracks for the movement of the movable block 7.

[0055] First guide rod 6: Fixed to the inner wall of the second slide groove 3, slidably connected to the movable block 7, playing a guiding role, ensuring that the movable block 7 moves along the predetermined direction, preventing it from deviating during the movement, and improving the accuracy of the movement of the movable block 7;

[0056] Movable block 7: Moves under the action of bidirectional threaded rod 5 and first guide rod 6. It is a key component connecting the steel structure support assembly and the steel structure limiting assembly. The adjustment of its position determines the position of subsequent support and limiting operations. It can be flexibly adjusted according to the length of the steel structure.

[0057] Connecting plate 8: Fixed to the right side of movable block 7, in the shape of "T", it provides an installation position for components such as the first hydraulic rod 9 and the fixed frame 10. At the same time, it is supported by the second roller 14 during movement to enhance stability.

[0058] First hydraulic rod 9: Installed inside the connecting plate 8, it pushes the fixed frame 10 up and down through the output end to realize the contact and separation of the steel structure support roller 12 and the first roller 13 with the steel structure. It is easy to operate and controls the lifting and lowering of the support structure.

[0059] Fixed frame 10: The lower end is connected to the second guide rod 11 to ensure smooth lifting and lowering, and the inner side is rotatably connected to the steel structure support roller shaft 12 to transmit the thrust of the first hydraulic rod 9 to the support roller shaft to provide support force for the steel structure;

[0060] The second guide rod 11 is slidably connected to the connecting plate 8 and plays a guiding role during the lifting and lowering of the fixed frame 10, ensuring that the fixed frame 10 lifts and lowers smoothly, preventing it from shaking, and improving the stability of the support structure.

[0061] Steel structure support roller 12: Rotatably connected to the inside of the fixed frame 10, the first roller 13 on the surface contacts the steel structure, and multiple support rollers share the weight of the steel structure to prevent the steel structure from bending and deforming due to its own weight, and continuously provide support when the angle of the steel structure is adjusted;

[0062] First roller 13: Rotates on the surface of the steel structure support roller 12, contacts the steel structure, reduces friction with the steel structure, and plays an auxiliary support and guiding role in the process of support and angle adjustment to ensure the stability of the steel structure;

[0063] The second roller 14 is divided into two groups and symmetrically arranged on the upper end of the steel structure processing table 1. It provides support when the movable block 7 and the connecting plate 8 move, reduces friction, plays a guiding role, ensures the accuracy of movement, and provides auxiliary support to the connecting plate 8 during the support process to enhance the overall stability.

[0064] The second fixed frame 15 is fixed on the movable block 7 and provides an installation position for components such as the rotating shaft 16 and the second drive motor 18. It is the supporting structure of the steel structure limit assembly.

[0065] Rotating shaft 16: Rotates inside the second fixed frame 15. It rotates by meshing with the gear 19 at the output end of the second drive motor 18 through the gear ring 17, which drives the connecting bracket 20, the second hydraulic rod 21 and the steel structure limiting plate 22 to rotate, so as to facilitate the adjustment of the angle of the steel structure.

[0066] Gear ring 17: Fixed on the surface of the rotating shaft 16, meshing with the gear 19 at the output end of the second drive motor 18, transmitting the power of the second drive motor 18 to the rotating shaft 16, thereby realizing the rotation of the rotating shaft 16;

[0067] The second drive motor 18 provides power to drive the gear 19 to rotate, which in turn drives the rotating shaft 16 to rotate. It is the power source for adjusting the angle of the steel structure, making it convenient for operators to control the angle of the steel structure.

[0068] Gear 19: meshes with gear ring 17 to transmit the rotational motion of the second drive motor 18 to the rotating shaft 16, ensuring effective power transmission and achieving stable rotation of the rotating shaft 16;

[0069] Connecting bracket 20: Fixed to the upper end of rotating shaft 16, with a second hydraulic rod 21 installed inside. It rotates along with rotating shaft 16, driving the second hydraulic rod 21 and steel structure limiting plate 22 to rotate and adjust the angle of the limiting plate.

[0070] The second hydraulic rod 21 extends into the inside of the rotating shaft 16, and its output end is connected to the steel structure limiting plate 22. By extending and retracting, it pushes the limiting plate closer to or away from the steel structure to achieve the limiting and positioning of the steel structure.

[0071] Steel structure limiting plate 22: It is arc-shaped and two sets are symmetrically arranged on the upper and lower sides of the rotating shaft 16. Under the push of the second hydraulic rod 21, it approaches the steel structure from the upper and lower directions, fits the shape of the steel structure, achieves precise positioning, and prevents the steel structure from shifting during processing.
