[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 4 ,as well as Figure 7 , which is the first embodiment of the present invention, provides a bracket for vertical motor maintenance, the device includes a support assembly 100 for supporting, an adjustment assembly 200 arranged in the support assembly 100 for placing vertical motors of different sizes, and a power assembly 300 arranged on one side of the support assembly 100 for controlling the movement of the adjustment assembly 200. The support assembly 100 is used to longitudinally support the vertical motor, which facilitates the staff to enter the bottom of the vertical motor for maintenance and replacement, thereby ensuring the safety of the staff. At the same time, the movement of the adjustment assembly 200 and the power assembly 300 is coordinated to adapt to vertical motors of different models and sizes, thereby enhancing the practicality of the device.

[0031] Among them, the support assembly 100 includes a base plate 101, an upper plate 102 for being placed on the ground and arranged above the base plate 101, a vertical plate 103 for setting the adjustment assembly 200, and a vertical plate 103 arranged between the base plate 101 and the upper plate 102. The vertical plate 103 is provided with multiple groups for supporting a space for the staff to work and ensure the safety of the work, an entrance 104 opened between the base plate 101 and the upper plate 102 for the staff to enter the space supported by the vertical plate 103, and a cover plate 105 arranged above the upper plate 102 for protecting the adjustment assembly 200.

[0032] During use, when the vertical motor needs to be repaired, the bracket is transported to the designated position by a forklift, so that the bottom plate 101 is fully in contact with the ground to keep the bracket stable. When the vertical motor to be repaired is large, the vertical motor is placed on the cover plate 105 by a crane, and the staff enters the lower position of the vertical motor through the entrance 104 to repair and replace the vertical motor.

[0033] When the outer diameter of the vertical motor to be repaired is smaller than the inner diameter of the cover plate 105, the power assembly 300 is used to control the movement of the adjustment assembly 200 so that the adjustment assembly 200 can support the vertical motor to be repaired. At this time, the vertical motor is placed on the adjustment assembly 200 by a crane. At this time, the staff enters the lower position of the vertical motor through the entrance 104 to repair and replace the vertical motor. When the repair is completed, the vertical motor is removed by the crane, and the adjustment assembly 200 is adjusted to support the next vertical motor to be repaired by the power assembly 300. When all the repair work is completed, the adjustment assembly 200 is controlled by the power assembly 300 to return to the initial position, and the bracket is moved to the warehouse by a forklift. When needed, it can be moved by a forklift.

[0034] Example 2

[0035] Reference Figure 1-Figure 3 ,as well as Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it supports vertical motors of different sizes.

[0036] Compared with Example 1, further, the adjustment component 200 includes a rotating circle 201 rotatably arranged between the upper plate 102 and the cover plate 105, which is used to cooperate with the power component 300 to rotate. The rotating circle 201 is rotatably connected with the upper plate 102 and the cover plate 105, and an adjusting member 202 arranged on the rotating circle 201 is used to cooperate with the rotation of the rotating circle 201 to open or contract and support the vertical motor, and an abutment block 203 is arranged on the inner wall of the rotating circle 201, which is used to abut the adjusting member 202 to prevent the adjusting member 202 from over-contracting.

[0037] Among them, the adjusting member 202 includes a supporting block 202a arranged on the upper surface of the upper plate 102, which is used to support the vertical motor, a connecting wheel 202b arranged at one end of the supporting block 202a, which is used to cooperate with the first rack 202c to follow the rotation of the rotating circle 201 to drive the supporting block 202a to open or contract, a first rack 202c arranged on the inner wall of the rotating circle 201 and meshing with the connecting wheel 202b, a connecting shaft 202d arranged at the center of the connecting wheel 202b, which is used to cooperate with the first shaft hole 202e to enable the supporting block 202a to rotate, and at the same time connect the upper plate 102 and the cover plate 105 and fix the position of the cover plate 105, and a first shaft hole 202e opened on the connecting wheel 202b to cooperate with the connecting shaft 202d.

[0038] Among them, the overall shape of the support block 202a is arc-shaped, which fits the inner diameter curvature of the upper plate 102. When the vertical motor to be repaired does not need the support of the support block 202a, the support block 202a can be completely retracted into the upper plate 102 and the cover plate 105 to avoid affecting the maintenance of personnel.

[0039] During use, when the outer diameter of the vertical motor to be repaired is smaller than the inner diameter of the cover 105, the power assembly 300 is started to drive the rotating circle 201 to rotate. At this time, the first rack 202c drives the support block 202a to rotate toward the center of the cover 105 through the connecting wheel 202b, and rotates until it can support the vertical motor to be repaired. At this time, the power assembly 300 is stopped and the position state of the support block 202a is locked. When all the maintenance work is completed, the power assembly 300 is used to control the rotating circle 201 to reverse, driving the support block 202a to retract. When the support block 202a comes into contact with the abutment block 203, the support block 202a is completely retracted into the upper plate 102 and the cover 105.

[0040] The remaining structures are the same as those of Example 1.

[0041] Example 3

[0042] Reference Figure 1 , Figure 2 , Figure 4 , Figure 6 ,as well as Figure 7 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the adjusting component 200 is driven to move.

[0043] Compared with Example 2, further, the power component 300 includes a mounting frame 301 arranged on the cover plate 105, the driving member 302 is never installed, the driving member 302 is arranged in the mounting frame 301, and is used to drive the rotating circle 201 to rotate, and a movable member 303 is arranged on the mounting frame 301, and is used to facilitate the installation of the driving member 302.

[0044] Among them, the mounting frame 301 includes an upper mounting block 301a arranged on the cover plate 105, which is used to cooperate with the lower mounting block 301b to install and fix the driving member 302, and a lower mounting block 301b arranged on the upper plate 102. The upper mounting block 301a and the lower mounting block 301b are connected by bolts.

[0045] Among them, the driving member 302 includes a motor 302a arranged on the lower mounting block 301b, which is used to generate driving power. The motor 302a is connected to an external power supply, a threaded shaft 302b arranged on the upper mounting block 301a, which is used to cooperate with the rotation of the motor 302a, and a second rack 302c arranged on the outer wall of the rotating circle 201 to cooperate with the threaded shaft 302b, which is used to cooperate with the rotation of the threaded shaft 302b to drive the rotating circle 201 to rotate. At the same time, with the structural characteristics of the threaded shaft 302b, the engagement between the threaded shaft 302b and the second rack 302c has a self-locking effect, which can prevent the support block 202a from rotating due to external force, thereby improving the safety performance of the bracket, and a transmission belt 302d arranged on the output end of the motor 302a and one end of the threaded shaft 302b, which is used to transmit the power generated by the motor 302a to the threaded shaft 302b, thereby driving the threaded shaft 302b to rotate.

[0046] Among them, the movable part 303 includes a fixed block 303a arranged at the bottom of the motor 302a, which is used to install the motor 302a, an adjusting stud 303b arranged on the fixed block 303a, which is used to cooperate with the adjusting nut 303c to adjust the movement of the fixed block 303a, so as to facilitate the installation and disassembly of the motor 302a and match various models of motors 302a at the same time, thereby improving the adaptability and practicality of the bracket, an adjusting nut 303c arranged on the adjusting stud 303b, a limiting shaft 303d arranged on the fixed block 303a, which is used to cooperate with the second shaft hole 303e to make the movement of the fixed block 303a more stable, and a second shaft hole 303e opened on the lower mounting block 301b to cooperate with the adjusting stud 303b and the limiting shaft 303d.

[0047] The lower mounting block 301b is fixedly connected to a set of vertical plates 103 to increase the stability of the operation of the motor 302a.

[0048] During use, when the outer diameter of the vertical motor to be repaired is smaller than the inner diameter of the cover plate 105, the motor 302a is started to drive the threaded shaft 302b to rotate. At this time, the threaded shaft 302b generates a thrust on the second rack 302c, driving the rotating circle 201 to rotate, so that the support block 202a rotates and opens to support the vertical motor to be repaired. When the motor 302a needs to be maintained, the transmission belt 302d is removed, and the output end of the motor 302a is separated from the lower mounting block 301b by rotating the adjusting stud 303b. At this time, the motor 302a can be removed. When the maintenance of the motor 302a is completed, the motor 302a is installed on the fixed block 303a, and the adjusting stud 303b is rotated to make the fixed block 303a push the output end of the motor 302a into the lower mounting block 301b, and the threaded shaft 302b is reinstalled.

[0049] The remaining structure is the same as that of Example 2.
