Description

Technical Field

[0001] The invention relates to the technical field of permanent magnet motors, and in particular to a generator rotor reinforcement ring cutting auxiliary device. Background Art

[0002] The direct-drive permanent magnet wind turbine generator consists of key components such as the stator, rotor, fixed shaft, rotating shaft, and bearings. The rotor has a special structure to ensure its strength during transportation and assembly and reduce its deformation. A reinforcing ring structure is added to the outer circumference of the rotor to ensure strength. After the generator is assembled, the reinforcing ring on the rotor needs to be cut off. The reinforcing ring cutting process uses cutting machines, grinders and other equipment. The cutting and grinding process generates metal shavings and a large amount of dust, which seriously pollutes the surrounding environment. In order to protect the surrounding environment, the traditional practice is to build a temporary enclosed cutting room and perform the reinforcing ring cutting and grinding operations in the cutting room. This method occupies a large area of ​​land, and the construction of a temporary cutting room requires at least two people to operate at the same time. The labor intensity is high and the construction process wastes time.

[0025] The invention discloses a generator rotor reinforcement ring cutting auxiliary device to improve the reinforcement ring cutting efficiency.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 5 As shown, the present application also discloses a generator rotor reinforcement ring cutting auxiliary device, which is used to seal the rotor reinforcement ring in a space, and includes: a frame 1, a fireproof cloth 2 and a running wheel 3. Among them, the fireproof cloth 2 is fixedly mounted on the frame 1, and the fireproof cloth 2 can be covered on the outside of the rotor reinforcement ring and form a sealed space with the rotor 5; the bottom end of the frame 1 is provided with a running wheel 3. The frame 1 in the present application is the supporting base of the entire auxiliary device, and its size and specific material can be selected according to different needs. Preferably, a material with high lightness and light weight can be used, such as a stainless steel square tube. The above-mentioned fireproof cloth 2 is covered on the frame 1. When in use, the fireproof cloth 2 can be covered on the outside of the rotor reinforcement ring, so that a sealed space is formed between the fireproof cloth 2 installed on the frame 1 and the rotor 5. The use of the fireproof cloth 2 can resist the damage of metal sparks and iron filings generated by metal cutting, thereby playing a protective role. The above-mentioned universal wheel 3 can drive the auxiliary device to move at will and reduce the labor intensity of the operator.

[0028] In the present application, the use of the device can greatly reduce the problem of cutting flames and dust flying around during the cutting process of the wind turbine rotor reinforcement ring, and reduce the degree of pollution to the surrounding environment. Compared with the traditional form of an integrated temporary cutting room, the use of the device can save space and does not require temporary construction, thereby improving the efficiency of the reinforcement ring cutting.

[0029] In a specific embodiment, the frame 1 is an open box-shaped structure and can be matched with the outer side of the rotor 5. When in use, the frame 1 is placed on the outer side of the rotor 5, and the open end is sealed and fitted with the outer side of the rotor 5, so that the rotor reinforcement ring is sealed in the sealed space. The size and shape of the frame 1 can be set according to different needs and are all within the protection range. In order to achieve sealing, the fireproof cloth 2 and the rotor 5 can be connected by pasting or adsorption.

[0030] In a further embodiment, the fireproof cloth 2 has an opening for personnel to enter and exit the sealed space, and the fireproof cloth 2 at the opening can be sealed and detachably connected to the rotor 5. After the fireproof cloth 2 wraps the frame, a portion of the protective cloth 2 is extended and can move freely, thereby forming an opening. When it is necessary to enter the sealed space to cut the rotor reinforcement ring, the operator can enter through the opening of the protective cloth 2, and then fit this place with the rotor 5 to form a sealed space.

[0031] In a preferred embodiment, the fireproof cloth 2 at the opening is connected to the rotor 5 by magnet adsorption. This connection method is simple to operate and can ensure a sealing effect. However, other methods that can achieve a sealed connection are also within the scope of protection. Magnetic materials are pasted at intervals on the edge of the fireproof cloth 2.

[0032] In a further embodiment, the frame 1 includes: an upper end face and a lower end face, a side face and a connecting face. The upper end face and the lower end face are used to fit with the rotor 5, and both the upper end face and the lower end face are arc-shaped faces that can fit with the rotor 5; the side face connects the upper end face and the lower end face, and a groove 4 is provided on the side face to cooperate with the rotor reinforcement ring. The number of grooves 4 is not limited to 1, and can be set to 2, 3 or more according to the external structural characteristics of the rotor 5; the connecting face connects the upper end face, the lower end face and the side face, and the connecting face is an arc-shaped face. The generator rotor reinforcement ring cutting auxiliary device disclosed this time is an arc-shaped structure, preferably a structure concentric with the rotor 5, so as to reduce the space occupied by the frame 1.

[0033] In order to facilitate the movement of the generator rotor reinforcement ring cutting auxiliary device, in the present application, a walking wheel 3 is arranged at the bottom end of the frame 1, and the walking wheel 3 is arranged as a universal wheel to facilitate the operation of the device.
