[0010] Beneficial effects

[0011] This utility model provides a mounting bracket for an excitation generator, which has the following advantages:

[0012] The guide support platform slides within the lifting platform groove via a slider, providing axial guidance for the rotor and, in conjunction with the hoisting equipment, enabling the rotor to be smoothly inserted into the stator; the auxiliary support assembly can adjust the height of the auxiliary support platform to provide auxiliary support for the ends of the rotor after insertion, facilitating the subsequent installation of the front and rear end covers;

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2 This utility model provides a technical solution: an excitation generator mounting bracket, including a base plate 1, a platform 2 on the upper wall of the base plate 1, a lifting platform 3 on one side of the platform 2, and an auxiliary support assembly on the other side. The lifting platform 3 has a sliding groove 4 along its length, and a slider 5 is provided in the sliding groove 4. A guide support platform 6 is fixedly provided on the upper wall of the slider 5. The four corners of the lower wall of the lifting platform 3 are connected to the base plate 1 by two pairs of telescopic rods 7. The base plate 1 is provided with a lifting assembly connected to the lifting platform 3.

[0019] By adopting the above technical solution, the stator is fixed on the pad 2, and the hoisting equipment hoists the rotor to the guide support platform 6. The hoisting equipment pushes the guide support platform 6 to make the rotor move axially along the slide groove 4 to insert into the stator. The auxiliary support assembly can support the end of the rotor after insertion. Through the mutual linkage of the above components, the risk of collision can be effectively reduced and the installation accuracy can be improved.

[0020] In this embodiment, the lifting assembly includes a pair of supports 8 fixedly mounted on the upper wall of the base plate 1, a pair of pull rods 9 rotatably mounted between the pair of supports 8, a slide rail 10 provided on the upper wall of the base plate 1, a pair of slide tables 11 slidably mounted on the slide rail 10 and screwed to the pull rods 9, a pair of connecting rods 12 hinged to the upper wall of the slide table 11, and the upper end of the connecting rods 12 hinged to the lower wall of the lifting platform 3.

[0021] By adopting the above technical solution, rotating the handwheel of the pull rod 9 causes the slide table 11 to move along the slide rail 10, which in turn drives the lifting platform 3 to rise and fall through the connecting rod 12, adjusting the height of the guide support platform 6 to adapt to different assembly height requirements and ensuring that the rotor and stator axes are aligned.

[0022] In this embodiment, the auxiliary support assembly includes a horizontal plate 13 fixedly installed on the side wall of the pad 2. A longitudinally arranged screw 14 is screwed onto the horizontal plate 13. A handwheel is provided at the lower end of the screw 14, and an auxiliary support platform 15 is rotatably installed at the upper end. A pair of guide rods 16 are fixedly provided on the lower wall of the auxiliary support platform 15, and a guide hole is provided on the horizontal plate 13 for the guide rods 16 to pass through.

[0023] By adopting the above technical solution, the handwheel of screw 14 is rotated to adjust the height of auxiliary support platform 15 so that it can support the end of the rotor, and guide rod 16 ensures that the support platform can be raised and lowered stably.

[0024] In this embodiment, a handwheel is further provided at one end of the pull rod 9.

[0025] By adopting the above technical solution, the handwheel operation is convenient and the height of the lifting platform 3 can be adjusted quickly.

[0026] In this embodiment, the lower wall of the slider 5 is provided with a push handle 17.

[0027] By adopting the above technical solution, the operator holds the push handle 17 and, in conjunction with the hoisting equipment, pushes the slider 5 to move along the slide groove 4, thereby driving the guide support platform 6 and the rotor to move axially.

[0028] In this embodiment, the upper walls of both the guide support platform 6 and the auxiliary support platform 15 are provided with V-shaped grooves.

[0029] By adopting the above technical solution, the V-shaped grooves on the guide support platform 6 and the auxiliary support platform 15 fit the outer circle of the rotor, providing stable support.

[0030] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0031] Example: During installation, the stator is fixed above the pad 2. The pull screw 9 handwheel is turned, and the slide 11 moves along the slide rail 10. The lifting platform 3 is raised and lowered through the connecting rod 12. The height of the guide support platform 6 is adjusted so that the center of the V-groove of the guide support platform 6 is flush with the stator axis. The hoisting equipment lifts the rotor into the V-groove of the guide support platform 6, ensuring that the rotor axis is consistent with the guide direction. The screw 14 handwheel is turned to adjust the height of the auxiliary support platform 15 so that its V-groove can support the end of the rotor after insertion. The push handle 17 is pushed, and the hoisting equipment is used to smoothly insert the rotor into the stator along the slide groove 4 axis. After the rotor is fully inserted, the auxiliary support platform 15 is released, and the lifting platform 3 is lowered before proceeding with the installation of subsequent end caps and other components.
