Embodiment Construction

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Therefore, the drawings and description are illustrative in nature, and are not used to limit the protection scope of the claims. In addition, in this specification, the drawings are not drawn to scale, and the same reference numerals denote the same parts.

[0034] According to the needs of the process, the stator 2 of the main motor for rough rolling is installed 800-1000mm below the ground 11, such as image 3 As shown, when installing t...

Abstract

The method for mounting a rotor of a large-sized synchronous motor includes steps of heightening a stator, laying a rail used for the rotor to penetrate through, mounting a guide limiting device of a rotor front bearing seat support on the rail, mounting limiting chain blocks and the like. The device for mounting the rotor of the large-sized synchronous motor comprises the rail, the rotor front bearing seat support, the guide limiting device of the rotor front bearing seat support, a positioning device and a drawing device. When a rotor of a roughing main motor is mounted according to the method and by the device, the motor rotor and the stator are less prone to collide with each other under the action of the guide limiting device and the positioning device, insulation loss caused by damages of coil insulation layers can be avoided, and mounting process is safe and reliable, so that motor mounting quality is guaranteed.

Description

Technical field [0001] The invention relates to a method and device for installing a rotor of a large synchronous motor, in particular to a method and device for installing a rotor of a large synchronous motor by a car crane in a closed workshop. Background technique [0002] At present, the main motor used for rough rolling in the steel rolling production workshop generally uses a synchronous motor, which has a relatively large power, usually above 4000KW. The main components of a synchronous motor include stator, rotor, bearing seat, base and end shield. The stator and rotor are usually delivered separately, each weighing more than 50 tons. Generally speaking, due to the insufficient lifting capacity of the bridge crane in the workshop, the bridge crane cannot be used to lift the stator and rotor when installing the motor. [0003] At present, there are two main methods for installing the stator and rotor of the main motor for rough rolling: one is to use H-shaped steel to desi...
