Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding, in particular to a welding cradle for H-shaped steel components. Background Art

[0002] The welding jig for H-shaped steel components, as a special process equipment, mainly bears the important responsibility of bearing weight and force, and is designed to facilitate the assembly and welding process of mechanical equipment. The design of the jig is flexible and changeable, and will be tailored according to the characteristics of different equipment and the specific requirements of the process. At present, the common welding jig for H-shaped steel components on the market usually adopts an L-shaped bracket design. This design can firmly support the H-shaped steel and ensure its stability during the welding process.

[0003] However, in actual applications, when it is necessary to weld connectors on the side of the H-beam, the existing frame design seems to be somewhat inadequate. Although it can effectively support the H-beam itself, it is difficult to provide effective auxiliary support for the connectors, which often leads to unstable position of the connectors during welding, thereby affecting welding quality and efficiency.

[0004] Therefore, we propose a welding frame for H-shaped steel members. Utility Model Content

[0005] The purpose of the utility model is to provide a tire frame for welding H-shaped steel components to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tire frame for welding H-shaped steel components, comprising: a base plate, an extension plate and a lifting and separation mechanism, the top end of the base plate is rotatably connected to a plurality of cylinders, the top end of the base plate is rotatably connected to a plurality of L-shaped brackets, one end of the plurality of L-shaped brackets is rotatably connected to a connecting rod, the output ends of the plurality of cylinders are rotatably connected to the connecting rod, one end of the plurality of L-shaped brackets is installed with an extension plate, the extension plate is installed with a holding head that can be equidistantly separated, and the extension plate is installed with a lifting and separation mechanism.

[0007] Preferably, the lifting and separation mechanism includes: a frame, a frame is fixedly connected to the top of the extension plate, a first threaded rod is rotatably connected inside the frame, a motor is rotatably installed inside the extension plate, the output end of the motor is fixedly connected to the first threaded rod, a T-shaped bracket is slidably connected to the inner wall of the frame, the T-shaped bracket and the first threaded rod, the interior of the T-shaped bracket is hollow, a middle fixed block is fixedly connected to the inner wall of the T-shaped bracket, moving blocks are equidistantly slidably connected on both sides of the fixed block inside the T-shaped bracket, a connecting rod group is rotatably connected between several moving blocks and the fixed blocks, an electric push rod is fixedly connected to one side of the T-shaped bracket, the output end of the electric push rod extends into the T-shaped bracket and is fixedly connected to one of the moving blocks, and the bottom ends of the moving block and the fixed block are fixedly connected to the supporting head.

[0008] Preferably, a placement groove is provided in the middle of the holding head, and a bolt is threadedly connected to one side of the holding head.

[0009] Preferably, the top end of the extension plate is fixedly connected to a lug plate, the middle portion of the lug plate is threadedly connected to a second threaded rod, and one end of the second threaded rod is rotatably connected to the fixed plate.

[0010] Preferably, an L-shaped embedded part is symmetrically fixedly connected to the bottom end of the base plate.

[0011] Preferably, H-shaped steel is placed on the top of several of the L-shaped brackets.

[0012] Preferably, a connecting piece is clamped inside the holding head.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Improved stability of the welding process: By adopting the rotating connection design of the cylinder and L-shaped bracket, the tire frame can flexibly adjust the height and position of the H-beam, thereby ensuring the stability of the H-beam during the welding process. In addition, the design of the holding head can firmly clamp the connecting parts, effectively preventing them from moving or deforming during the welding process, greatly improving the welding accuracy and stability.

[0015] Enhanced auxiliary support function: To address the problem of insufficient support for existing tire frames when welding connectors on the side of H-shaped steel, this technical solution achieves effective auxiliary support for the connectors by installing a lifting and separation mechanism on the extension plate. The first threaded rod is driven by a motor to rotate, and the T-shaped bracket can slide in the frame, and then the equidistant separation between the supporting heads is achieved through the movement of the connecting rod group to accommodate connectors of different sizes. This design not only improves the stability of the connectors during welding, but also reduces the difficulty of welding and improves work efficiency.

[0016] Flexible Adjustment and Strong Adaptability: The tire frame's structural design is flexible and adaptable, allowing it to be tailored to the specific characteristics of different equipment and process requirements. Components such as the cylinder, L-shaped bracket, gripping head, and lifting and separating mechanism can all be adjusted as needed to accommodate H-beams and connectors of varying sizes and shapes. This design makes the tire frame highly adaptable and capable of meeting diverse welding requirements.

[0017] Easy to operate, safe and reliable: Bolts secure the support head, ensuring its stability and facilitating its replacement and maintenance. The L-shaped embedded parts secure the tire frame securely to the ground or other foundation, preventing it from shifting or tipping due to vibration or external forces. Furthermore, the automated control of the motor and electric push rod makes operation simple and quick, reducing operational difficulty and labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Working principle:

[0027] First, the base plate 1 serves as the foundation for the entire tire frame and is securely fixed to the ground or other foundation via L-shaped embedded parts 13. Several cylinders 2 and L-shaped brackets 3, rotatably connected to the base plate 1, form the main structure of the tire frame. The telescopic movement of the cylinders 2 is connected to the L-shaped brackets 3 via connecting rods 4, enabling flexible adjustment of the height of the H-beam 14. This design allows the tire frame to accommodate H-beams 14 of varying sizes, ensuring stability during the welding process.

[0028] An extension plate 5 is mounted at one end of the L-shaped bracket 3, onto which are mounted equally spaced retaining heads 6. These are designed to securely hold the connector. A central slot 8 and bolts 9 on one side ensure secure gripping of workpieces of varying shapes and sizes, while also facilitating replacement and maintenance.

[0029] To provide effective auxiliary support for the connector, a lifting and separation mechanism 7 is also installed on the tire frame. This mechanism includes a frame 71, a first threaded rod 72, a motor 73, a T-shaped bracket 74, a central fixed block 75, a movable block 76, a connecting rod assembly 77, and an electric push rod 78. The motor 73 drives the first threaded rod 72 to rotate, causing the T-shaped bracket 74 to slide within the frame 71. The movement of the connecting rod assembly 77 changes the distance between the movable block 76 and the fixed block 75, thereby driving the support head 6 to achieve equidistant separation. This design allows the support head 6 to adapt to connectors of different sizes and provide effective auxiliary support.

[0030] In addition, an ear plate 10 and a second threaded rod 11 are fixed to the top of the extension plate 5. By adjusting the position of the second threaded rod 11, the fixing plate 12 can be flexibly adjusted, thereby further enhancing the stability and adaptability of the tire frame.

[0031] During welding, the H-beam 14 is first placed on top of the L-shaped bracket 3. The clamping head 6 securely grips the H-beam 14 and the connector by adjusting the cylinder 2 and the lifting and separating mechanism 7. Then, the motor 73 and electric push rod 78 control the lifting and separating movements of the clamping head 6, adjusting to different welding positions and angles, based on the welding process requirements. Throughout the welding process, the bracket provides stable support and auxiliary support, ensuring welding quality and efficiency.

[0032] In summary, the H-shaped steel 14 component welding frame effectively solves the problem of insufficient support of existing frames when welding connecting parts through its unique design and flexible working principle, improves the stability and efficiency of the welding process, and has high practical value and market prospects.
