Description

Technical Field

[0001] The utility model relates to the technical field of transformer installation, in particular to a hanging device for a transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. In the current transformer manufacturing process, each component of the transformer is usually manufactured separately first, and then the transformer is assembled. During the transformer assembly process, since the installation process of each component of the transformer is relatively complicated, the transformer is usually suspended by a hanging device, so that there is a distance between the bottom of the transformer and the ground, making the installation process of each component on the transformer more convenient.

[0003] In this regard, China's patent application number: CN202222046166.X discloses a hanging device for transformer installation, including a frame for installing other mechanisms to lift the transformer and limit the lifting range of the device, the frame is provided with a lifting mechanism for adjusting the hanging height of the device, and the lifting mechanism is provided with multiple sets of connecting mechanisms for connecting the transformer and the lifting mechanism. The utility model provides connection points by setting multiple sets of connecting mechanisms to connect the lifting ears above the transformer with the device, thereby fixing the transformer at multiple points to avoid shaking of the transformer during the lifting process.

[0004] The device can improve the stability of the transformer by setting up multiple sets of connecting mechanisms, but the connecting mechanisms can only pull the top of the transformer and cannot limit the bottom of the transformer. In addition, the middle part of the connecting mechanism is movable. During the hanging process of the transformer, the bottom is prone to shaking, causing the transformer to collide with the frame and even causing the device to topple over.

[0005] Therefore, in order to solve the above problems, a hanging device for a transformer is proposed. Utility Model Content

[0006] The utility model aims to provide a hanging device for a transformer, so as to solve the problem that the device in the prior art mentioned in the above background technology can improve the stability of the transformer by setting multiple groups of connecting mechanisms, but the connecting mechanism can only pull the top of the transformer and cannot limit the bottom of the transformer, and the middle part of the connecting mechanism is movable. During the hanging process of the transformer, the bottom end is prone to shaking, causing the transformer to collide with the frame, and even causing the device to tip over.

[0007] To achieve the above object, the utility model provides the following technical solution: a hanging device for a transformer, comprising: a base, a bracket is installed on the top surface of the base, and a hydraulic cylinder is installed on the inner side of the bracket;

By rotating the threaded rod, which is threadedly connected to the movable block, the rotation of the threaded rod can drive the movable block to slide on the guide rod, and the position of the movable block on the movable plate can be adjusted. This facilitates adjusting the position of the movable block according to the position of the lifting lugs at the top of the transformer, so that the movable block is located above the lifting lugs. Then, the threaded post is inserted through the lifting lugs at the top of the transformer, and the lifting rope passes through the lifting lugs. By rotating the rotating hand disc, the threaded post is screwed onto the bottom surface of the movable block, and the threaded post can be fixed on the movable block.
