Description

Technical Field

[0001] The utility model relates to the technical field of transformer processing devices, in particular to a fixing tool for an inclined elevated seat. Background Art

[0002] At present, in the manufacturing process of large power transformers, in order to meet the insulation distance between the bushing and the bushing end, the transformer needs to adopt an installation method in which the bottom surface of the transformer riser is an inclined surface. However, as the voltage level of the transformer increases, the diameter and height of the riser become larger, and the mass of the riser becomes heavier. The larger the welding angle, the greater the eccentricity of the center of gravity of the riser. Once the riser is placed vertically and unstable, it is easy to cause rollover, posing a safety hazard. In addition, during transportation, or before being installed in the transformer, the riser needs to be installed inside the riser, and the current transformer must be placed stably to carry out the process.

[0005] Furthermore, the distance between the upper vertical plates at both ends is smaller than the distance between the lower vertical plates at both ends, and the upper vertical plates are located on the inner side surfaces of the lower vertical plates;

[0006] Furthermore, the upper base plate and the lower base plate are both circular structures, and the diameter of the upper base plate is smaller than the diameter of the lower base plate;

[0007] Furthermore, an upper reinforcing rib is welded between the inner side of the upper vertical plate and the upper base plate, and a lower reinforcing rib is welded between the outer side of the lower vertical plate and the lower base plate;

[0010] Furthermore, the inclination angle between two vertically adjacent positioning holes on the lower vertical plate is 1.5°.

[0011] The beneficial effect of the present invention is that after the lifting seat is assembled on the upper base plate, since the upper vertical plate and one end of the lower vertical plate are rotatably connected, a corresponding plurality of positioning holes are opened on the end surfaces of the other ends of the upper vertical plate and the lower vertical plate, and the upper vertical plate is connected to the lower vertical plate through positioning parts that cooperate with the positioning holes.

[0016] like Figures 1-4 As shown, the utility model is a fixing tool for an inclined elevated seat, comprising an upper base plate 1 and a lower base plate 2. Upper vertical plates 3 are provided at both ends of the bottom surface of the upper base plate 1, and lower vertical plates 4 are provided at both ends of the top surface of the lower base plate 2. The elevated seat (not shown in the figure) is assembled on the upper base plate 1, and the upper vertical plate 3 is rotatably connected to one end of the lower vertical plate 4. A plurality of corresponding positioning holes 5 are opened on the other end surfaces of the upper vertical plate 3 and the lower vertical plate 4. The upper vertical plate 3 is connected to the lower vertical plate 4 through a positioning piece 9 that cooperates with the positioning hole 5.

[0017] The distance width between the upper vertical plates 3 at both ends is smaller than the distance width between the lower vertical plates 4 at both ends, and the upper vertical plates 3 are located on the inner side of the lower vertical plates 4; the upper base plate 1 and the lower base plate 2 are both circular structures, and the diameter of the upper base plate 1 is smaller than the diameter of the lower base plate 2; an upper reinforcing rib 6 is welded between the inner side of the upper vertical plate 3 and the upper base plate 1, and a lower reinforcing rib 7 is welded between the outer side of the lower vertical plate 4 and the lower base plate 2.

[0018] A plurality of screw holes 8 are provided in a circumferential direction on the upper base plate 1 , and the raising seat and the upper base plate 1 are connected by the screw holes 8 and studs.

[0019] The positioning holes 5 on the upper vertical plate 3 are arranged in a horizontal direction. In this embodiment, a row of positioning holes 5 is provided on the upper vertical plate 3 , and the row is provided with three positioning holes 5 .

[0020] The positioning holes 5 on the lower vertical plate 4 are arranged in a vertical arc shape. There are three rows of positioning holes 5 on the lower vertical plate 4, and each row is provided with 4 positioning holes 5. The inclination angle between two vertically adjacent positioning holes 5 on the lower vertical plate 4 is 1.5°. Then the minimum inclination angle between the upper base plate 1 and the lower base plate 2 is 1.5°, and the maximum adjustment angle is 15°.

[0021] Figure 4 This is an assembly structure diagram when the inclination angle between the upper base plate 1 and the lower base plate 2 is 15°.

[0022] In the present invention, under normal conditions, the angle between the upper base plate 1 and the lower base plate 2 is 0°, and the lifting seat is assembled on the upper base plate 1. Since the upper vertical plate 3 is rotatably connected to one end of the lower vertical plate 4, the lifting seat can be adjusted to a vertical direction with this end as the rotation fulcrum. Subsequently, the positioning member 9 (bolts can be used) is inserted into the corresponding positioning hole 5 and tightened with a nut 10, so that the lifting seat can be placed stably in an upright position. It is suitable for lifting seats with different inclination angles and diameters, solves the problem of vertical and stable placement of the lifting seat during the installation of the current transformer and transportation, can prevent tipping, and has a wide range of applications.
