[0001] The utility model belongs to the technical field of steel structure welding auxiliary equipment, and in particular relates to a device for preventing welding deformation of a partition plate and a reinforcement ring. Background Art

[0002] In the production process of box girder steel structure, it is usually necessary to weld reinforcement rings on the inner side of some partitions with elliptical holes in the middle. Currently, workers usually weld them directly on one side of the partition. Since the partition is thin and has no stress release, the deformation is large when welding with the reinforcement ring (for example, the edge is warped), and it is difficult to correct after welding. In addition, during the welding process, it cannot be guaranteed that the reinforcement ring is in close contact with the inner wall of the partition during welding. Summary of the invention

[0003] The utility model aims to solve the problem that during the existing process of direct welding of the partition plate and the reinforcement ring by workers, the partition plate is greatly deformed and the reinforcement ring cannot be fixed. A device for preventing the partition plate and the reinforcement ring from being deformed during welding is provided. The partition plate is fixed above the operating platform by angle steel, and the reinforcement ring is fixed by multiple vertical plates and adjustment columns to avoid deformation or displacement during the welding process of the partition plate and the reinforcement ring.

[0010] Preferably, the adjusting member is a hydraulic cylinder, the telescopic end of which is fixedly connected to the bottom of the corresponding column, and the column is driven to rise and fall by the hydraulic cylinder.

[0011] Through the above technical solution, the beneficial effects of the utility model are:

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0019] like Figure 1-2 As shown, this embodiment provides a device for preventing welding deformation of the partition and the reinforcement ring, which is used to assist the partition 1 and the reinforcement ring 2 in welding and forming, and includes an operating platform 3, on which a partition 1 is arranged, a welding hole is arranged in the middle of the partition 1, and a reinforcement ring 2 is arranged in the welding hole, and the outer wall of the reinforcement ring 2 is in contact with the inner wall of the welding hole, which is beneficial for subsequent welding of the contact position, and two angle steels 4 are arranged above the partition 1, and the two angle steels 4 are respectively located on both sides of the welding hole, and both ends of each of the angle steels 4 extend out from above the partition 1 and are fixedly connected to the operating platform 3 by studs 5, and the overall fixation of the partition 1 on the operating platform 3 is realized by the angle steels 4 and the studs 5.

[0020] A plurality of vertical plates 6 are also fixedly arranged on the operating platform 3. The plurality of vertical plates 6 are arranged in a circumferential array inside the reinforcement ring 2 along the reinforcement ring 2, and an adjustment column 7 is threadedly penetrated on each of the vertical plates 6. One end of each of the adjustment columns 7 is vertically facing the inner wall of the reinforcement ring 2. The reinforcement ring 2 is fixed by placing the reinforcement ring 2 in the partition 1 and then rotating a plurality of adjustment columns 7 at a time so that their ends are pressed against the inner wall of the reinforcement ring 2.

[0021] A plurality of legs are arranged below the operating platform 3 to support the operating platform 3. Each of the legs includes a column 8 and a support column 9. The support column 9 is a hollow cylinder. The lower end of the column 8 extends into the support column 9. An adjusting member 10 is arranged in the support column 9. The adjusting member 10 is located directly below the corresponding column 8 and is used to realize the lifting and lowering adjustment of the column 8. The column 8 is driven to lift and lower in the support column 9 by the adjusting member 10. During this process, the movement of the column 8 is limited by the support column 9.

[0022] The adjusting member 10 is a jack, which has a simple structure, is economical and has a significant effect.

[0023] The adjusting member 10 is a hydraulic cylinder, and its telescopic end is fixedly connected to the bottom of the corresponding column 8, so it is easy to adjust.

[0024] When in use, first place the reinforcement ring 2 on the outside of multiple vertical plates 6 on the operating platform 3, then rotate multiple adjustment columns 7 to press against the inside of the reinforcement ring 2 to fix the reinforcement ring 2, then put the partition 1 on the outside of the reinforcement ring 2 and place it on the operating platform 3, and place two angle steels 4 above the two ends of the partition 1, and fix the angle steels 4 on the operating platform 3 through studs 5, so as to fix and limit the partition 1, and then start welding the position where the inner side of the partition 1 contacts the reinforcement ring 2. In this process, by fixing the reinforcement ring 2 and the partition 1, the movement of the two during the welding process is effectively avoided, and the limiting fixation of the partition 1 by the angle steel 4 greatly reduces the deformation of the partition 1 during the welding process, so that the partition after welding is flat and the deformation is small.

Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
