Description

Technical Field

[0001] The invention relates to the field of mechanical installation, and in particular to an internally supported manipulator for transporting a high-speed motor stator. Background Art

[0002] As a high-speed motor, the magnetic levitation fan has a large motor power, a large stator volume, and a large weight, and requires a hoist to cooperate with the hoisting. From the stator core processing to the stator winding, and then to the installation into the motor housing, at least 6 hoists are required. The stator and the motor housing are connected by interference fit. During the assembly process, the motor housing needs to be heated before the stator is installed. At the same time, the space inside the motor housing is limited. After the stator is installed in the housing, the hoist needs to be removed from the inner hole. Therefore, this type of stator hoist must have the characteristics of compact structure and easy disassembly. The four-petal flange structure hoist currently used has the following disadvantages: 1. Disassembly and assembly takes a long time and the work efficiency is low; 2. Manual close-range operation is required. When disassembling the hoist, the operator needs to put his arm into the motor. Due to the high temperature and the sharp edges of the silicon steel sheets inside the stator, it is easy to get injured and the safety is poor. Summary of the invention

[0003] Technical purpose: In view of the shortcomings of existing high-speed motor stator lifting tools, the present invention discloses a high-speed motor stator handling internal support manipulator with simple structure, convenient stator loading and unloading, high safety, and remote operation and control.

[0006] A boss hole is provided at the top center of the elastic sleeve, and the pull rod passes through the boss hole and is connected to the connecting rod. The boss hole can enhance the bearing capacity of the overall structure; the side of the elastic sleeve is evenly divided into support plates, and in a natural state, the outer diameter of the elastic sleeve is smaller than the diameter of the inner ring of the stator; the thickness of the middle part of the support plate is greater than the thickness at both ends, and changes linearly, and a protruding bottom angle is provided at the bottom end of the support plate to support the lower end face of the stator during hoisting, so that the stator will not fall off due to the reduced friction between the inner wall and the elastic sleeve during hoisting, thereby ensuring the safety of hoisting.

[0007] Preferably, the slider is a conical slider, the taper of which is the same as the inclination of the lower end of the support plate, and is provided with a center hole and a pull rod connection, with the small end facing the inside of the elastic sleeve.

[0008] Preferably, a circular protrusion is provided at the bottom end of the pull rod to prevent the slider from falling off and improve the bearing capacity.

[0009] Preferably, the piston and the connecting rod can be fixedly connected or integrally formed, and the other end of the connecting rod is fixedly connected to the pull rod.

[0010] Preferably, there are two lifting ears, which are fixed symmetrically on the top of the elastic sleeve with respect to the bracket to ensure the stability of the lifting.

[0011] When the present invention is used, the lifting ear is connected to the lifting equipment, the high-speed motor stator lifting tool is controlled to the top of the stator, the lifting tool is dropped to the bottom of the stator inner hole, the pneumatic switch is started, the air valve is controlled to make the piston move upward, and the pull rod connected to it drives the slider upward. Due to the taper between the slider and the support plate, the support plate is pressed against the stator inner hole, and the protruding bottom angle of the support plate is located at the bottom end of the lower end surface of the stator. The lifting equipment is controlled to lift the stator to a suitable position, the air valve is controlled to make the piston move downward, drive the cone block to move downward, and the elastic sleeve is contracted. The lifting equipment is controlled to move out the high-speed motor stator lifting tool to complete the stator lifting.

[0012] Beneficial effects: The high-speed motor stator handling internal support manipulator provided by the present invention remotely controls the movement of the piston through a pneumatic switch, does not require close-range operation, has good safety, and a high degree of automation; there is no complicated structural disassembly and assembly, which improves work efficiency; the support plate of the spring sleeve is provided with a protruding bottom angle, which plays a lifting protection role, prevents the inner wall of the stator from slipping and falling out, and further improves safety.

[0019] A boss hole 9 is provided on the top of the elastic sleeve 3, and the upper end of the pull rod 2 passes through the boss hole 9 and is connected to the connecting rod 8. When the elastic sleeve 3 is in a natural state, the outer wall diameter is smaller than the inner hole diameter of the stator 13 to be hoisted; the side of the elastic sleeve 3 is evenly divided into support plates 10, the thickness of the middle part of the support plate 10 is greater than the thickness at both ends, and the thickness changes in a linear manner, and a protruding bottom angle 12 is provided on the side of the bottom of each support plate 10, which can support the lower end face of the stator 13 during hoisting to prevent it from falling off due to slipping of the inner wall of the stator 13, thereby ensuring the safety of hoisting.
