Technical Field

[0001] The present application relates to the technical field of transformer installation, and in particular to a fixing frame of a transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Transformers are basic equipment for power transmission and distribution and are widely used in industries, agriculture, transportation, urban communities and other fields.

[0003] The transformer needs to be installed on the electric pole through a fixing frame. The existing method is to install the fixing frame on the electric pole, then suspend it through lifting equipment, place the transformer on the bracket, and then perform the final fixation. Since the transformer has a certain weight, it is difficult to carry it manually, so when suspending it, the mounting holes between the fixing frame and the transformer must be connected, which requires the staff to cooperate with each other, which is difficult and has a low safety factor.

Positioning components 5 are provided on the front, rear, left and right sides of the transformer 2 on the fixing frame 1, and tightening components 6 are also provided between the multiple positioning components 5 and the fixing frame 1, and the multiple positioning components 5 are tightened in four directions of the transformer 2 by the tightening components 6.

[0020] Reference Figure 3 The positioning component 5 includes a positioning frame 51 fixed on the fixing frame 1 and a positioning plate 52 arranged on the positioning frame 51, and also includes a pull rope 53. The positioning plate 52 drives the pull rope 53 to be pressed against the side of the transformer 2 through the tightening component 6. The positioning component 5 also includes a guide rod 54 fixed on the positioning plate 52 and passing through the positioning frame 51, and a return spring 55 arranged between the positioning plate 52 and the positioning frame 51 and sleeved on the outer end of the guide rod 54. A U-shaped frame 56 is also fixed on the positioning plate 52, and the U-shaped frame 56 is also fixed on the fixing frame 1. The positioning frame 51 slides through it, one end of the pull rope 53 is connected to the U-shaped frame 56, and it also includes a guide seat 57 fixed on the fixing frame 1. The positioning frame 51 and the guide seat 57 are both provided with a guide wheel 58, the pull rope 53 is wound around the guide wheel 58, and the other end of the pull rope 53 is connected to the No. 1 screw sleeve 62 and the No. 2 screw sleeve 63. The positioning component 5 can achieve a rapid positioning effect when the transformer 2 is installed, and can quickly and safely cooperate with the lifting equipment. At the same time, it can also enhance the stability after the transformer 2 and the fixing frame 1 are installed.

[0021] Reference Figure 3 The tightening component 6 includes a bidirectional screw 61 installed in the fixing frame 1 and a No. 1 screw sleeve 62 fitted on one end of the bidirectional screw 61, and a No. 1 screw sleeve 62 fitted on the other end of the bidirectional screw 61. The positioning plate 52 moves toward the outside of the transformer 2 through the reset spring 55. A handwheel 64 is fixed at one end of the bidirectional screw 61. The No. 1 screw sleeve 62 and the No. 2 screw sleeve 63 move synchronously in opposite directions with the spiral of the bidirectional screw 61. The tightening component 6 can synchronize and link multiple positioning components 5, which has the advantages of convenient operation and high consistency.

[0022] Working principle: the connecting frame 3 and the connecting ring 4 are installed on the electric pole, and then the fixing frame 1 is fixed on the connecting frame 3 by bolts to form a complete fixing bracket. All the positioning components 5 are in the maximum open state. The transformer 2 is suspended above the fixing frame 1 by the lifting equipment, and then the bottom of the transformer 2 is close to the fixing frame 1. At this time, the lower part of the transformer 2 is located between multiple positioning components 5. The suspension staff roughly adjusts the position of the transformer 2, and then the installation staff turns the handwheel 64, and the handwheel 64 drives the bidirectional screw 61 to rotate. The No. 1 screw sleeve 62 and the No. 2 screw sleeve 63 are connected to the bidirectional screw. The spiral of the lever 61 moves outward synchronously, and the No. 1 screw sleeve 62 and the No. 2 screw sleeve 63 pull the multiple pull ropes 53 synchronously, and the positioning plate 52 is driven to move toward the transformer 2 under the action of the guide wheel 58. The multiple positioning plates 52 move toward the middle synchronously, and the transformer 2 in a suspended state is moved to just above the installation position of the fixed frame 1, and then the lifting equipment places the transformer 2 on the fixed frame 1. At this time, the transformer 2 is docked with the installation position on the fixed frame 1. The staff fixes the transformer 2 on the fixed frame 1 with bolts, and then tightens the positioning component 5 for the final time. The positioning component 5 plays a structural reinforcement role after the transformer 2 is installed.

[0023] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
