[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change AC voltage, current, and impedance. It has wide applications in power transmission, electronic equipment, and industrial fields.

[0003] During transformer winding assembly, due to the limited spacing between adjacent windings, they are often tied together with ropes and then lifted by an overhead crane. This process requires workers to repeatedly tie and untie the ropes, resulting in low efficiency. Therefore, this application proposes a lifting tool for transformer winding assembly to solve this problem. Summary of the Invention

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0018] Please see Figure 1-4 This application provides a technical solution for a lifting tool for assembling transformer windings: a lifting tool for assembling transformer windings includes a support beam 1, a lifting ring 2 is provided on the upper surface of the support beam 1, and the support beam 1 is connected to two support arms 8 through two adjustable groups 3.

[0019] There are two lifting rings 2. The adjustment group 3 is located on the outer side of the support beam 1. The support arm 8 consists of a long rod and a support plate. The support plate is located at the bottom of the long rod and is used to support the winding.

[0020] Adjustable side stops 9 are provided on both sides of the support arm 8.

[0021] The adjustable side stop assembly 9 includes a side stop 10, a mounting base 11, a movable plate 12, a connecting rod plate 13, a support plate 14, a screw 15, and a handwheel 16. Mounting bases 11 are provided on both sides of the support arm 8. The side stop 10 is hinged to one side of the mounting base 11. The support plate 14 is provided on the outer side of the side stop 10. The screw 15 is rotatably connected to one side of the support arm 8. The movable plate 12 is threadedly connected to the outer side of the screw 15. The handwheel 16 is provided at the other end of the screw 15. The connecting rod plates 13 are rotatably connected to both sides of the movable plate 12. The connecting rod plates 13 are hinged to the support plate 14.

[0022] Furthermore, the movable plate 12 is in the shape of an "I", and the two side baffles 10, the mounting base 11, the connecting rod plate 13 and the support plate 14 are symmetrically arranged about the movable plate 12.

[0023] The side baffle 10 is designed to limit the winding. The support plate 14 is designed to facilitate the movement of the side baffle 10 by the connecting rod plate 13. The connecting rod plate 13 is designed to transmit the power output by the moving plate 12. The screw 15 and handwheel 16 are designed to adjust the position of the moving plate 12, thereby adjusting the angle of the two side baffles 10, which facilitates the side baffles 10 to limit windings of different sizes.

[0024] With this configuration, by turning the handwheel 16, the screw 15 is rotated, causing the moving plate 12 to move closer to or further away from the support arm 8. The moving plate 12 then drives the connecting rod plate 13, the support plate 14, and the side baffle 10 to rotate around the hinge point between the side baffle 10 and the mounting base 11, changing the angle of the side baffle 10 to facilitate the limiting of windings of different sizes.

[0025] Furthermore, the adjustable distance group 3 includes a movable hole 4, a limiting groove 5, a limiting block 6, and a connecting seat 7. Two movable holes 4 are opened on the support beam 1. At least two limiting grooves 5 are provided at the bottom of the movable hole 4. The connecting seat 7 is slidably connected in the movable hole 4. The bottom of the connecting seat 7 passes through the movable hole 4 and is connected to the support arm 8. Limiting blocks 6 are provided on both sides of the connecting seat 7. The limiting blocks 6 are placed in the limiting grooves 5.

[0026] The movable hole 4 is designed to facilitate the movement of the limit block 6 within the movable hole 4. The limit block 6 and the limit groove 5 are designed to facilitate the adjustment of the position of the support arm 8.

[0027] When it is necessary to adjust the distance between the two support arms 8, lift the support arm 8 upwards so that the limiting block 6 moves out of the limiting groove 5, move the support arm 8 laterally, adjust the position of the limiting block 6 in the movable hole 4 until it is aligned with the other limiting groove 5, and then put it down so that the support arm 8 can be used to hoist windings of different sizes.

[0028] Furthermore, the limiting groove 5 is semi-circular, and the limiting block 6 is a cylinder, so that the limiting block 6 can be placed in the limiting groove 5, and when the winding is removed, the support arm 8 can be pulled outward to rotate the support arm 8 around the limiting block 6, so as to remove the support arm 8.

[0029] Furthermore, the movable hole 4 includes a horizontal hole and a vertical hole. The horizontal hole extends through the front and rear of the support beam 1, and the vertical hole is located at the bottom of the horizontal hole.

[0030] When in use: When adjusting the distance between the two support arms 8 according to the size of the winding, lift the support arm 8 upward so that the limit block 6 moves out of the limit groove 5, move the support arm 8 laterally, adjust the position of the limit block 6 in the movable hole 4 until it is aligned with the other limit groove 5, and then put it down. Repeat the above operation to adjust the position of the other support arm 8.

[0031] The lifting ring 2 on the support beam 1 is hoisted by the overhead crane, and the two support arms 8 are placed above the winding. Then, the support arms 8 are gently pulled outward and slowly lowered by the overhead crane. After the support plate contacts the bottom of the winding, the support arms 8 are released, so that the support plate on the lower surface of the support arm 8 contacts the bottom of the winding. Then, by turning the handwheel 16, the screw 15 is rotated, so that the moving plate 12 is moved away from the support arm 8. The moving plate 12 drives the connecting rod plate 13, the support plate 14 and the side baffle 10 to rotate around the hinge point between the side baffle 10 and the mounting base 11, changing the angle of the side baffle 10, so that the side baffle 10 contacts the winding, and the overhead crane lifts it.

[0032] When removing the winding, the support arm 8 can be pulled outward to rotate around the limit block 6, so as to remove the support arm 8.

[0033] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
