[0002] An existing patent (publication number: CN118619162A) discloses a motor repair lifting device. It includes a base, a repair workbench, a motor, and a protective support mechanism. The base has casters installed at its bottom corner, and a fixed frame is fixed to the right side of the base. Support plate one and support plate two are movably connected at their middle ends. A liner is fixed near the bottom of support plate one, and a lifting control mechanism is connected below the liner. A lifting mechanism is connected to the middle of the repair workbench, and the motor is located at the top center of the workbench. However, this device relies on the repair workbench on the base to lift the motor. When repairing a heavy motor, multiple operators are required to manually place the motor on the top of the workbench, increasing the operators' workload and affecting the equipment's efficiency. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a motor maintenance lifting device. This device utilizes two sets of rope wheels at the bottom of the motor hanger, driven by a motor to rotate the rope wheels, which lift the motor. Simultaneously, a first lead screw motor on the side of the equipment support drives the hanger lead screw to rotate, causing the hanger lead screw to move the rope wheels inside the crossbeam column to the maintenance platform for repair. When lifting and repairing heavy motors, no operator intervention is required, thus increasing the equipment's work efficiency.

[0004] The objective of this utility model is achieved through the following technical solution:

The motor hanger slides inside the guide rod of the crossbeam. The side of the motor hanger has a roller groove that matches the roller. The roller groove connects to the roller, which rotates inside the roller groove. The roller rotates on the upper part of the hanger crossbeam. The lower part of the motor hanger is fixedly connected to the suspension. The lower part of the suspension is fixedly connected to the rope wheel frame. The rope wheel frame matches the rope wheel and connects to the rope wheel. The rope wheel rotates inside the rope wheel frame. The side of the rope wheel frame is fixedly connected to the rope wheel motor. The inside of the rope wheel motor is fixedly connected to the rope wheel. The inside of the equipment support is fixedly connected to the lifting platform positioning frame. The front of the lifting platform has a lifting platform positioning groove.

[0006] The lifting platform positioning frame is adapted to the lifting platform positioning groove, the lifting platform positioning frame is connected to the lifting platform positioning groove, the lifting platform positioning groove slides on the side of the lifting platform positioning frame, the side of the lifting platform is fixedly connected to the central screw frame, and the side of the screw handle seat has a screw.

[0007] The screw is threaded inside the central screw frame. The side of the lifting platform has a lifting screw shaft groove, which is adapted to the lifting screw. The lifting screw shaft groove is connected to the lifting screw, and the lifting screw rotates inside the lifting screw shaft groove. The rear part of the lifting screw shaft groove is fixedly connected to the second screw motor. The second screw motor is fixedly connected to the lifting screw inside.

Beneficial effects

[0008] 1. During the use of this utility model motor repair lifting device, the two sets of rope wheels at the bottom of the motor hanger are driven by motors to rotate, so that the rope wheels lift the motor. Then, the first screw motor on the side of the equipment support drives the hanger screw to rotate, so that the hanger screw drives the rope wheel inside the crossbeam column to move to the repair platform for repair. When lifting and repairing a relatively heavy motor, there is no need for the operator to move it, thereby increasing the working efficiency of the equipment.

[0009] 2. During the use of this utility model motor repair lifting device, the motor is supported by two sets of repair platforms at the rear of the equipment bracket. The screw handle seats inside the two sets of lifting platforms drive the screw to rotate, so that the screw adjusts the distance between the two sets of repair platforms. This allows the equipment to adjust the distance according to the actual needs of the motor and facilitates the repair of some irregularly shaped motor parts at the bottom, thereby increasing the adaptability of the equipment.

[0010] 3. During the use of this utility model motor maintenance lifting device, the two sets of second lead screw motors on the side of the lifting platform jointly drive the internal lifting lead screw to rotate, so that the lifting lead screw drives the two sets of outer end support rods and inner end support rods to lift and raise the maintenance platform, so that the two motors work together to reduce the load of a single motor and thus increase the service life of the equipment.
