The longitudinal, vertical and transverse positioning of the motor during assembly is achieved by 3 different positioning members, respectively, as shown in fig. 1 and 2.
(1) Longitudinal positioning of linear motor 5
The longitudinal positioning of the motor is achieved by means of a longitudinal traction stop 1 at the end of the suspension bracket arm 6. One side of the longitudinal traction stop seat 1 is fixed on the end part of the bracket arm 6 through 4M 10 hexagon socket screws, and the other side is fixed on the upper surface of the hanger of the linear motor 5 through four M10 hexagon screws. The longitudinal traction stop 1 is shown in fig. 3.
As shown in fig. 3, the traction stop seat is connected with the bracket arm 6 and the motor hanger through the support plate 1.4, so that the motor can be longitudinally positioned, the fixing bolt hole 1.1 in the drawing adopts a long groove type design, and the motor can be finely adjusted in the assembly process, so that the assembly is convenient. When the component is designed, two lightening holes 1.2 are formed in the reinforcing rib plate 1.3 to achieve the aim of lightening, and the triangular rib plate 4.2 is chamfered in the right-angle connection position of the reinforcing rib plate 1.3 and the supporting plate 1.4 to facilitate welding.
(2) The linear motor 5 is positioned transversely
The motor is transversely fixed by the transverse stop seats on two sides of a longitudinal beam, one end of each side of 4 total 8 transverse stop seats is fixed on the side surface of the longitudinal beam through screws, and the other end of each side of the 4 total 8 total transverse stop seats is fixed on the side surface of a hanger of the linear motor 5. In order to prevent the motor from being over-positioned in the longitudinal direction and the vertical height of the motor from being adjustable, the fixing holes of the transverse stop seat cannot be designed into a round shape, the vertical direction of the holes is an elongated slot, and the longitudinal dimension cannot limit the motor to be subjected to front and rear fine adjustment. After the motor is longitudinally positioned, the motor is transversely positioned. The stop can in fact also take up part of the motor's own weight and the vertical forces caused by the normal forces, thereby also protecting the vertical suspension bolts. The lateral stop 1 is shown in fig. 4.
Considering that the middle position of the suspension frame has fewer bearing devices, the structure form of the transverse stop seat is correspondingly adjusted, and the second transverse stop seat 4 is shown in fig. 5.
Compared with the transverse stop seat 1, the structure has the advantages that the corresponding structural change is carried out, but the transverse positioning effect is not influenced, the triangular rib plates 4.2 are added, and the strength and the stability of the structure are improved.
(3) Vertical positioning of linear motor 5
The motor is hung at the lower part of the longitudinal beam and the bracket arm 6 by 8 sets of hanging devices in the vertical direction. When the linear motor 5 is installed, vertical positioning is firstly carried out, and the 8 sets of hanging devices with adjustable heights are utilized to adjust the distance between the lower surface of the motor iron core and the upper surface of the F-rail aluminum cover plate to be 3mm in a car falling state.
The installation is shown in fig. 6, the vertical hanging device 2 of the linear motor 5 consists of an outer sleeve 2.3, an adjusting screw sleeve 2.2 and an adjusting screw 2.1, wherein the inner part of the outer sleeve 2.3 is provided with threads, the outer part of the adjusting screw sleeve 2.2 is provided with threads, the outer part of the adjusting screw 2.1 is provided with threads, the outer sleeve 2.3 penetrates through holes on the upper surfaces of the longitudinal beam and the bracket arm 6 during the specific installation, and the upper part of the vertical hanging device is fixed on the upper surfaces of the longitudinal beam and the bracket arm 6 through 4 uniformly distributed cross screws; the adjusting screw sleeve 2.2 is screwed in through the matching of the external screw thread and the internal screw thread of the outer sleeve 2.3, so that the height can be adjusted; the adjusting screw 2.1 is inserted from the inside of the adjusting screw sleeve 2.2 and screwed into the corresponding position of the hanger of the linear motor 5 through the external thread at the lower part to play a role in fixing the linear motor 5, and the height adjustment of the linear motor 5 is realized through the matching effect of the adjusting screw sleeve 2.2 and the adjusting screw 2.1.
The suspension frame is one of key components of the magnetic levitation train, has extremely important influence on the running safety, comfort and reliability of the train, and the linear motor 5 is taken as one of key components of the suspension frame, and has particularly important influence on the performance of the suspension frame. According to the invention, by adding the longitudinal positioning and transverse positioning devices, the longitudinal, vertical and transverse positioning of the linear motor 5 during assembly is respectively realized by 3 different positioning components, the positioning mode of the linear motor 5 is improved, and the traction power and braking capacity and efficiency of the magnetic levitation train, as well as the reliability, safety and usability of the vehicle are improved; and the longitudinal and transverse positioning of the linear motor 5 can be ensured, and the assembly, maintenance and repair of the linear motor 5 are facilitated.
