Abstract
Description
Technical Field
[0001] This utility model relates to a processing table, specifically to an assembly and welding table for the main housing of a nacelle transformer. Background Technology
[0002] A nacelle transformer, or simply nacelle transformer, is a transformer used in wind turbine generator sets. Installed inside the nacelle of a wind turbine generator set, the nacelle transformer converts the electrical energy generated by the wind turbine into a voltage level suitable for transmission to the power grid, thereby ensuring the stable operation of the power system.
[0003] The main housing of the engine room transformer has an opening at one end to allow for the installation of the iron core, windings and cooling components inside. The main housing of the engine room transformer is usually assembled and welded from multiple plate structures. Before this invention, the general welding platform lacked a suitable limiting and fixing structure, resulting in low assembly efficiency and low welding accuracy of the main housing of the engine room transformer. Utility Model Content
[0004] Based on the content in the background art, in order to achieve rapid assembly and limited fixing during welding of the main shell of the engine room transformer, this utility model provides an assembly and welding table for the main shell of the engine room transformer, which includes a base, equal-height support, stop bar, first bracket, second bracket, first slide groove, first baffle, support plate, second upper slide groove, second lower slide groove and second baffle.
[0005] Multiple equal-height supports are fixedly connected to the left and right sides of the top surface of the base, and a baffle is integrally connected to the outer side of the equal-height support, the height of the baffle protruding from the top surface of the equal-height support.
[0006] The first bracket and the second bracket are respectively located on the front and rear sides of the top surface of the base;
[0007] The first support consists of an upper crossbeam, a lower crossbeam, and two first columns. The two first columns are arranged opposite to each other and fixedly connected to the top surface of the base. At least one first sliding groove is fixedly connected to the inner side of the first column. The first sliding groove has a first sliding hole in the front and rear horizontal direction. Each first sliding groove has a corresponding first baffle passing through the first sliding hole. The first baffle is located inside the corresponding baffle.
[0008] The upper crossbeam is fixedly connected between the tops of the two first columns, and at least one support plate is fixedly connected to the bottom surface of the upper crossbeam. The lower crossbeam is fixedly connected between the lower parts of the two first columns.
[0009] The second support consists of two opposing second columns. The second columns are fixedly connected to the top surface of the base. A second upper sliding groove and a second lower sliding groove are fixedly connected to the side of the second column. The second upper sliding groove is located above the second lower sliding groove. The second upper sliding groove and the second lower sliding groove are each provided with a second sliding hole in the left and right horizontal directions. The second upper sliding groove and the second lower sliding groove are each provided with a corresponding second baffle passing through their second sliding hole.
[0010] The operating principle of the above-mentioned assembly and welding station is as follows:
[0011] The main casing of the engine room transformer is composed of a first side plate, a second side plate, a first bending plate, and a second bending plate;
[0012] First, place the second bending plate on the same height support, inside each stop bar, so that the front flange face of the second bending plate is in contact with the lower crossbeam. Then, insert the second baffle into the second sliding groove of the two second columns and make it fit with the rear bending face of the second bending plate. This will limit the second bending plate between the lower crossbeam and the second baffle.
[0013] When the first side plate is placed on the same height support on one side of the base, the front end of the first side plate is in contact with the corresponding first column, and the rear end of the first side plate is in contact with the inner rear end of the second bent plate. The first baffle is inserted into the first groove of the first column on this side and is in contact with the inner side of the first side plate, so that the first side plate can be limited between the corresponding baffle and the first baffle.
[0014] After limiting the second side plate to the same height support on the other side of the base in the same way, place the first bent plate on the support plate of the upper crossbeam and make the front flange face of the first bent plate fit with the upper crossbeam. Insert the second baffle into the second upper sliding groove of the two second columns and fit with the rear bending face of the first bent plate. This will limit the first bent plate between the upper crossbeam and the second baffle.
[0015] This allows for the rapid assembly and precise positioning of the various plates of the main housing of the engine room transformer on the assembly and welding table. This positioning and fixing prevents the plates from easily wobbling, improving welding precision. After assembly and welding, it also facilitates the welding of other auxiliary components, such as reinforcing ribs and mounting brackets, to the plates. Once all welding is complete, the first and second baffles can be removed, and the main housing of the engine room transformer can then be lifted off the assembly and welding table.
[0016] Preferably, multiple flexible pads are fixedly connected to the rear side of the upper crossbeam, the rear side of the lower crossbeam, and the rear side of the first column. The front flange face of the second bent plate, the front face of the first side plate, the front face of the second side plate, and the front flange face of the first bent plate are respectively in contact with the corresponding pads to avoid wear on the contact surfaces of the plate structures.
[0017] Furthermore, at least one support column is fixedly connected to the middle of the base to further support the middle of the second bent plate.
[0018] Furthermore, a limiting plate is fixedly connected to the end of the first baffle and the end of the second baffle, and a gripper is fixedly connected to the limiting plate to facilitate the staff to hold the first baffle and the second baffle.
[0019] Through the above technical solutions, this utility model has at least the following beneficial effects:
[0020] The assembly and welding table for the main housing of the nacelle transformer described in this application, through the coordinated design of structures such as the base, equal-height support, stop bar, first bracket, second bracket, first slide, first baffle, support plate, second slide and second baffle, can realize the rapid assembly and limiting fixation of multiple plate structures. After the limiting fixation, the plate structures of the nacelle transformer housing will not easily shake, thus improving the assembly and manufacturing efficiency and welding accuracy of the main housing of the nacelle transformer.

[0030] The first bracket and the second bracket are respectively located on the front and rear sides of the top surface of the base 1;
[0031] The first support consists of an upper crossbeam 11, a lower crossbeam 12 and two first columns 13.

Then, insert the second baffle 24 into the second sliding groove 23 of the two second columns 21 and make it fit with the rear bending surface of the second bending plate 34. This will limit the second bending plate 34 between the lower crossbeam 12 and the second baffle 24.
