[0002] As a large-scale power equipment, the size and weight of the transformer are usually quite considerable. Especially in the power system, large transformers are widely used. The weight and size of these transformers make them difficult to move by conventional manpower or simple machinery. Therefore, a hanging device is needed to assist the installation of the transformer.
[0003] The current hanging device usually uses a hook to fix the transformer to be hung, and then drives the hoisting rope to be reeled in by a winch to hang the transformer. Since the hoisting rope does not limit the transformer when it is reeled in, the transformer is prone to shaking during the hanging and lifting process. In addition, the transformer lacks anti-falling measures during the hanging process. If the hoisting rope breaks, the transformer will fall, which will not only cause economic losses but also easily cause harm to personal safety. Utility Model Content

[0020] A movable plate 3 is slidably sleeved on the inverted L-shaped plate 2 to facilitate position limiting and avoid shaking. A hanging plate 4 is fitted at the bottom of the movable plate 3, and a hook is installed at the bottom of the hanging plate 4 to facilitate connecting the hanging ear of the transformer. A lifting plate 5 is provided above the movable plate 3, and a sliding rod 7 is connected between the hanging plate 4 and the lifting plate 5. A lifting rope 6 is connected to the lifting plate 5, and a winding assembly for winding up the lifting rope 6 is installed at the top of the inverted L-shaped plate 2;
[0021] The winding assembly includes a shell 19 installed on the top of an inverted L-shaped plate 2, a winding roller 20 is rotatably installed in the shell 19, and a motor 21 for controlling the rotation of the winding roller 20 is installed on the outside of the shell 19. A through hole for the suspension rope 6 to pass through is opened at the top of the inverted L-shaped plate 2, and the suspension rope 6 is installed on the winding roller 20.
[0022] A compression spring 8 connected between the movable plate 3 and the lifting plate 5 is sleeved on the slide bar 7, and the lifting plate 5 is supported by the tension of the compression spring 8. A groove 9 set along its height is provided on the side wall of the inverted L-shaped plate 2, and evenly distributed grids 10 are installed at the bottom of the groove 9. A cardboard groove connected to the groove 9 is provided in the movable plate 3, and a cardboard 11 is slidably installed in the cardboard groove, and a return spring 12 is installed between the cardboard 11 and the bottom of the cardboard groove.
[0023] A steering pulling mechanism is installed between the card plate 11 and the lifting plate 5, which is convenient for applying pulling force to the card plate 11 to compress the reset spring 12. The steering pulling mechanism includes a protrusion 13 installed on the top of the card plate 11, and a through groove for the protrusion 13 to move is provided at the top of the card plate groove. A steering wheel 14 is installed on the movable plate 3, and a hidden groove 22 connected to the through groove is opened on the top of the movable plate 3.

A pull rope 15 that bypasses the steering wheel 14 is connected to the bottom of the lifting plate 5, and the pull rope 15 is connected to the protrusion 13.
[0024] The working principle of the utility model is as follows: the hook at the bottom of the hanging plate 4 is connected to the hanging ear at the top of the transformer, and the motor 21 is started to drive the winding roller 20 to wind up the hanging rope 6, so that the transformer can be hung and lifted. During the lifting process, the movable plate 3 slides along the inverted L-shaped plate 2, so that the transformer will not shake during the hanging and lifting process. Starting the hydraulic cylinder 18 can make the inverted L-shaped plate 2 drive the moving seat 16 to slide along the guide groove 23, so as to adjust the position of the hanging transformer. The reaction force of the compression spring 12 is used to support the lifting plate 5, so that the hanging plate 4 is always in a position when the transformer is not hung. It keeps in fit with the bottom of the movable plate 3, and under the action of the steering wheel 14, the pull rope 15 applies tension to the protrusion 13, so that the card plate 11 is located in the card plate groove and compresses the reset spring 12. When the transformer is hung on the hanging plate 4, its gravity is balanced by the hanging rope 6. When the hanging rope 6 breaks, the lifting plate 5 will be quickly driven close to the movable plate 3 under the clamping of the weight of the transformer, so that the pull rope 15 is relaxed, causing the reset spring 12 to reset, and pushing the card plate 11 to extend into the groove 9 and engage with the grid 10 to limit the position, so that the transformer will not fall after the hanging rope 6 breaks.
[0025] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
