[0001] The utility model relates to the technical field of power station equipment maintenance, in particular to an adjustable main transformer fan motor disassembly and maintenance device. Background Art

[0002] Currently, the disassembly of the main transformer fan motor relies on manual work, which is labor-intensive and has high safety risks.

[0003] 1. Comparative document CN113696149B discloses an aircraft generator disassembly and assembly device, and the protected claim is: "It includes a first moving mechanism, a second moving mechanism, a third rotation adjustment mechanism, a first rotation adjustment mechanism, a second rotation adjustment mechanism and a clamping mechanism connected in sequence, the first moving mechanism is used to drive the second moving mechanism to move along the first direction; the second moving mechanism is used to drive the third rotation adjustment mechanism to move along the second direction; the third rotation adjustment mechanism is used to drive the first rotation adjustment mechanism to rotate around the third direction; the first rotation adjustment mechanism is used to drive the second rotation adjustment mechanism to rotate around the first direction; the second rotation adjustment mechanism is used to drive the clamping mechanism to rotate around the second direction.

[0018] See also Figures 1 to 3 , an adjustable main transformer fan motor disassembly and maintenance device, comprising a motor clamp 1, wherein the two ends of the motor clamp 1 are respectively connected to a first clamp mounting bracket 2.1 and a second clamp mounting bracket 2.2, wherein the first clamp mounting bracket 2.1 is connected to a first rotating shaft 3.1, wherein the second clamp mounting bracket 2.2 is connected to a second rotating shaft 3.2, wherein the first rotating shaft 3.1 and the second rotating shaft 3.2 are respectively connected to a load-bearing bracket 4, wherein a positioning plate 5 and a crank handle 6 are provided at the right end of the second rotating shaft 3.2, wherein the load-bearing bracket 4 is assembled on a support beam 9 through a first bottom bracket 8.1, wherein a second bottom bracket 8.2 is provided between the two first bottom brackets 8.1, wherein a support base 10 is provided at the top of the second bottom bracket 8.2. The design of the utility model takes into consideration the convenience of operation and the applicability of the equipment, and can provide a safe and effective working platform for the disassembly and maintenance of the main transformer fan motor.

[0019] Preferably, the side wall of the load-bearing bracket 4 fixing the second rotating shaft 3.2 is provided with a positioning bracket 7, and the positioning plate 5 is provided with positioning holes 5.1 around the plate body, and the positioning plate 5 can be connected and fixed with the positioning bracket 7 through the step pin 11. The device is designed with the positioning plate 5 and the positioning bracket 7, which cooperate with each other to ensure the stable position of the motor during maintenance and prevent any unexpected movement.

[0020] Preferably, the load-bearing bracket 4 is connected to the rotating shaft 3 via a bearing seat 4.1, and the top of the load-bearing bracket 4 is connected to the bearing seat 4.1 via bolts. The utility model adopts a modular design, and in order to meet the needs of rapid disassembly and assembly, the modules are mostly connected by bolts.

[0021] Preferably, the two ends of the motor fixture 1 are connected to the first fixture mounting bracket 2.1 and the second fixture mounting bracket 2.2 by bolts, the middle section of the motor fixture 1 is arc-shaped, and rubber pads are provided on the inner walls of the motor fixture 1 and the fixture mounting bracket 2.

[0022] The working principle of this embodiment is as follows:

[0023] Its working principle is based on providing a variable position maintenance platform for the main transformer fan motor. Before use, the operator places the motor rotor horizontally on the motor fixture 1, which cooperates with the fixture mounting bracket 2 and can slide left and right along the horizontal axis to adapt to the size of the motor rotor and achieve fixation.

[0024] After the motor rotor is fixed, the operator activates the shaft 3 by rotating the crank 6 to drive the motor rotor to rotate. This rotation allows the motor rotor to flip from a horizontal position to a 90° vertical position for easy maintenance operations. When the required vertical maintenance position is reached, the positioning plate 5 and the positioning bracket 7 are locked using the step pin 11 to ensure that the motor is in a stable position during maintenance and prevent any unexpected movement.

[0025] After the maintenance is completed, the operator will remove the step pin 11 and rotate the crank 6 again to return the motor rotor to the initial horizontal position, ready for the next operation or maintenance. The design of this device takes into account the convenience of operation and the safety of the maintenance process, ensuring the stability of the motor and the safety of the operator during maintenance activities.
