Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-deformation welding, specifically to an anti-deformation welding device for steel structures. Background Technology
[0002] During steel structure construction, steel beams are usually connected to the foundation or other frame structures through structural plates. During the welding process, steel structures are prone to deformation. Welding deformation refers to the changes in shape and size of the workpiece being welded due to the effect of an uneven temperature field. The changes that change with temperature are called instantaneous welding deformation, and the changes when the workpiece is completely cooled to its initial temperature are called residual welding deformation.
[0003] For example, Chinese utility model patent CN216680929U discloses a deformation prevention device for steel structure welding, belonging to the field of steel structure welding equipment. This device includes a lower deformation prevention clamp, with a steel structure body mounted on its upper end. A lower left fixing block is fixedly connected to the left end of the lower deformation prevention clamp, and a sleeve is fixedly connected to the upper end of the lower left fixing block. A rotating block is rotatably connected to the upper end of the sleeve, and a threaded hole is drilled at the upper end of the rotating block. The threaded hole communicates with the sleeve, and a sliding tube is inserted into the threaded hole. The sliding tube passes through the threaded hole and slides against the inner wall of the sleeve. The outer end of the sliding tube is threaded, and the thread matches the threaded hole. This allows the deformation prevention device for steel structure welding to have a good adjustment effect. Adjustment is made according to the steel structure being subjected to deformation prevention operations, making the device suitable for most steel structures and improving its applicability.
[0004] However, the existing devices have the following shortcomings in actual use: when the devices perform clamping operations by using threaded blocks and slots, there is a certain gap between the slots, which means they can only be used to fix and clamp steel structures of a specific size, thus reducing the range of applications for clamping steel structures. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a steel structure anti-deformation welding device that facilitates clamping and anti-deformation operations on steel structures of different sizes and thicknesses, thereby improving the device's application range and convenience, and enhancing its practicality.
[0006] This utility model discloses a steel structure anti-deformation welding device, which includes a welding table, a lower clamping plate and two upper clamping plates. The lower clamping plate is fixedly installed on the top of the welding table, and the steel structure to be welded is clamped between the top of each upper clamping plate and the lower clamping plate. Each upper clamping plate is provided with a clamping mechanism at its top.
[0007] The clamping mechanism includes a pressure plate, the bottom of which is tightly fitted to the top of the upper clamping plate. Two fixed plates are symmetrically fixed to the top of the pressure plate, and a rotating shaft is rotatably mounted between the two fixed plates. A connecting plate is rotatably mounted on the rotating shaft, and a sliding plate is fixedly mounted to the top of the connecting plate. A screw is screwed onto the sliding plate, and the bottom of the screw is rotatably connected to the top of the welding table. A limit mechanism is provided on the outer wall of the pressure plate. This steel structure anti-deformation welding device moves the sliding plate longitudinally while rotating the screw, and simultaneously moves the connecting plate, moving the steel structure to be welded to the top of the lower clamping plate. As the connecting plate moves, the pressure plate is simultaneously brought into contact with the top of the upper clamping plate by the rotation shaft and the fixed plates. The limit mechanism limits the top of the pressure plate, thus stably clamping the steel structure between the lower and upper clamping plates. This device is suitable for clamping and preventing deformation of steel structures of different sizes and thicknesses, improving its application range, convenience, and practicality.
[0008] Preferably, the limiting mechanism includes a movable plate, which is screwed onto the outer wall of the screw. A limiting plate is fixedly installed on the outer wall of the movable plate. The inner side wall of the top of the limiting plate is in contact with the top of the pressure plate. The movable plate and the limiting plate are moved synchronously by rotating the screw. The bottom end of the limiting plate is in contact with the top of the pressure plate, thereby limiting the rotating pressure plate.
[0009] Preferably, a support platform is rotatably mounted on the bottom area of the outer side wall of the screw, and the bottom end of the support platform is fixedly connected to the top end of the welding table. By installing the support platform, the bottom area of the screw during rotation is supported, thereby improving the stability of the screw during rotation.
[0010] Preferably, the bottom end of each of the upper clamping plates is fixedly connected to the top of the welding table by multiple springs. By installing the springs, it is easy for the upper clamping plates to return to their initial state.
[0011] Preferably, the top ends of the two upper clamping plates are fixedly connected by two reinforcing ribs. By installing the reinforcing ribs, the connection effect of each upper clamping plate when fixing the steel structure is improved.
[0012] Preferably, a limiting groove is provided at the bottom end of the lower clamping plate, and a lower base plate is fixedly installed at the bottom end of the limiting plate. The limiting groove and the top end of the lower base plate are tightly fitted together. By installing the lower base plate, the limiting plate for sliding operation is limited.
[0013] Preferably, two 17s are fixedly installed on the top of the welding table. By installing the 17s, it is convenient to adjust the height of the two pressure plates simultaneously.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This steel structure anti-deformation welding device, by rotating the screw, simultaneously drives the sliding plate to move longitudinally. Simultaneously, the sliding plate moves the connecting plate, moving the steel structure to be welded to the top of the lower clamping plate. Simultaneously, the connecting plate, through the transmission of the rotating shaft and the fixed plate, simultaneously drives the pressure plate to contact the top of the upper clamping plate. A limiting mechanism limits the top of the pressure plate, thus stably clamping the steel structure between the lower and upper clamping plates. This facilitates clamping and anti-deformation operations for steel structures of different sizes and thicknesses, improving the device's application range, convenience, and practicality.

Detailed Implementation
[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0021] This utility model discloses a steel structure anti-deformation welding device, which includes a welding table 1, a lower clamping plate 2 and two upper clamping plates 3. The lower clamping plate 2 is fixedly installed on the top of the welding table 1. The steel structure to be welded is clamped between the top of each upper clamping plate 3 and the lower clamping plate 2. Each upper clamping plate 3 is provided with a clamping mechanism at its top.
[0022] The clamping mechanism includes a pressure plate 4, the bottom end of which is tightly fitted to the top end of the upper clamping plate 3. Two fixing plates 5 are symmetrically fixedly installed on the top end of the pressure plate 4. A rotating shaft 6 is rotatably installed between the two fixing plates 5. A connecting plate 7 is rotatably installed on the rotating shaft 6. A sliding plate 8 is fixedly installed on the top end of the connecting plate 7. A screw 9 is screwed onto the sliding plate 8. The bottom end of the screw 9 is rotatably connected to the top end of the welding table 1. A limiting mechanism is provided on the outer wall of the pressure plate 4. The limiting mechanism includes a moving plate 10, which is screwed onto the outer wall of the screw 9. A limiting plate 11 is fixedly installed on the outer wall of the moving plate 10. The inner side wall of the top of the limiting plate 11 is in contact with the top of the pressure plate 4. The bottom area of the outer side wall of the screw 9 is rotatably mounted with a support platform 13. The bottom end of the support platform 13 is fixedly connected to the top of the welding table 1. The bottom end of each upper clamping plate 3 is fixedly connected to the top of the welding table 1 by multiple springs 14. The top ends of the two upper clamping plates 3 are fixedly connected by two reinforcing ribs 15. The bottom end of the lower clamping plate 2 is provided with a limiting groove 12. The bottom end of the limiting plate 11 is fixedly mounted with a lower base plate 16. The limiting groove 12 is tightly fitted with the top of the lower base plate 16. The top of the welding table 1 is fixedly mounted with two 17s.
[0023] like Figures 1 to 4 As shown, this utility model discloses a steel structure anti-deformation welding device. During operation, a support platform 13 supports the bottom area of the rotating screw 9, improving its stability. The installation 17 facilitates simultaneous height adjustment of the two pressure plates 4. Simultaneously, rotating the screw 9 drives the sliding plate 8 longitudinally. The bottom end of the limiting plate 11 abuts against the top end of the pressure plate 4, limiting its movement. The movement of the sliding plate 8 also simultaneously moves the connecting plate 7, allowing the screw to be welded to the desired position. The welded steel structure moves to the top of the lower clamping plate 2. As the connecting plate 7 moves, the pressure plate 4 is simultaneously driven to contact the top of the upper clamping plate 3 under the transmission of the rotating shaft 6 and the fixing plate 5. By installing reinforcing ribs 15, the connection effect of each upper clamping plate 3 when fixing the steel structure is improved. The top of the pressure plate 4 is limited by the limiting mechanism, so that the steel structure is stably clamped between the lower clamping plate 2 and the upper clamping plate 3. The lower clamping plate 2 and the upper clamping plate 3 provide anti-deformation support for the steel structure. By installing springs 14, it is easy for the upper clamping plate 3 to return to its initial state.
[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
