Description

Technical Field

[0001] This utility model relates to the technical field of welding workbench, specifically a welding workbench for end plate reinforcement plates of power equipment supports. Background Technology

[0002] Power equipment supports are generally welded together from a top plate, a support column, a bottom fixing plate, and reinforcing plates. After welding and grinding to remove weld slag and other defects, the steel supports are hot-dip galvanized as a whole. When used to support power equipment in power systems, they are generally used in substations to support surge arresters, current transformers, voltage transformers, insulators, GIS, etc. The bottom of these power equipment is connected to the steel pipe support via a base.

[0003] During the fabrication of the support column, the top plate and bottom fixing plate need to be welded to both ends of the column. Then, multiple reinforcing plates are welded circumferentially to the connection points between the column and the top plate and bottom fixing plate. When welding the end plates, the traditional workbench uses a pure steel beam support. However, raising the workbench by the support makes welding the end plates and reinforcing plates inconvenient and unstable. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content

Plate 16 and connecting plate 16 are fastened to side plate 8 by bolts to realize the connection and disassembly between pressure seat 10 and side plate 8. Left wheel 3 and right wheel 4 are respectively rotated and engaged with first semi-circular bearings 9 on both sides and pressure seat 10 through wheel axle 16. Second semi-circular bearing 18 is provided inside pressure seat 10. Second semi-circular bearing 18 is engaged with wheel axle 16 to ensure smooth rotation of left wheel 3 and right wheel 4, so that it can be easily rotated manually. The distance between left wheel 3 and right wheel 4 of the same support mechanism 2 does not exceed 5cm to ensure that the normal diameter support column will not fall between left wheel 3 and right wheel 4. An electric cylinder 11 is provided in the left frame 5 of one of the supports. The piston rod of electric cylinder 11 is provided with brake block 12, and brake block 12 is engaged with the corresponding left wheel 3.

[0020] like Figure 3As shown, the left frame 5 and the right frame 6 have the same structure and are both composed of a vertical plate 13, a horizontal plate 14 and a top plate 15. There are two vertical plates 13 and they are vertically connected to the bottom plate 7 respectively. Several horizontal bars are set between the vertical plates 13. The top of each vertical plate 13 is connected to the top plate 15. The piston rod of the electric cylinder 11 passes through the vertical plate 13 on the inner side of the corresponding left frame 5. The vertical plate 13 has a through hole to accommodate the piston rod of the electric cylinder 11. The left frame 5 and the right frame 6 with this structure can ensure the structural strength on the one hand and facilitate the installation of the electric cylinder 11 on the other hand.

[0021] Installation method and operating principle: First, weld two upright plates 13, several horizontal plates 14 and top plate 15 to obtain the left side frame 5 and the right side frame 6 respectively. Then, weld two side plates 8 between the left side frame 5 and the right side frame 6. Finally, weld the bottom plate 7 to the bottom of the left side frame 5, the right side frame 6 and the side plate 8 to obtain the bracket. Subsequently, a countersunk hole is made in the first semi-circular bearing 9, and the first semi-circular bearing 9 is installed in the slots of the side plate 8 by bolts and the countersunk hole. Then, the left wheel 3 and the right wheel 4 are supported in the corresponding first semi-circular bearing 9 by the wheel axle 16. Then, the pressure seat 10 with the second semi-circular bearing 18 is connected to the side plate 8 by the connecting plate 16 and bolts. At this time, the wheel axle 16 of the left wheel 3 and the right wheel 4 is clamped between the first semi-circular bearing 9 and the second semi-circular bearing 18, completing the assembly of the support mechanism 2. Finally, the base plate 7 of each support mechanism 2 is fastened to the upper surface of the base 1 by bolts. Then, the electric cylinder 11 is placed in the corresponding left frame 5 (this is not limited to the left frame 5, it can also be installed in the right frame 6), and the electric cylinder 11 is fastened to the outer upright plate 13 by bolts. After the piston rod of the electric cylinder 11 passes through the inner upright plate 13, the brake block 12 is inserted into the piston rod of the electric cylinder 11 and fastened by bolts to complete the installation. In use, the support column is horizontally supported on the left wheel 3 and right wheel 4 of each support mechanism 2 by the cooperation of the overhead crane and the electric hoist. Figure 4 As shown, the end plate is manually aligned and welded to one end of the support column. Then, a reinforcing plate is welded between the support column and the end plate. The manual welding position is generally at the top or side. When the support column needs to be rotated, it can be rotated directly. During welding, the piston rod of the electric cylinder 11 extends and the brake block 12 abuts against the surface of the corresponding left wheel 3 to prevent the support column from rotating. This utility model has a reasonable structure. Several support mechanisms 2 are provided on the upper surface of the base 1. Each support mechanism 2 has a left wheel 3 and a right wheel 4 installed within a bracket. With the support of the left wheel 3 and right wheel 4, the column can rotate when welding the end plate or reinforcing plate to the end of the support column, greatly improving convenience and reducing the difficulty of manual welding. Simultaneously, an electric cylinder 11 is installed within one of the brackets. The piston rod of the electric cylinder 11 cooperates with the left wheel 3 through the brake block 12, thereby preventing the support column from rolling during welding.
