Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions are used herein for the purpose of descripti...

Abstract

The invention relates to a walking robot and a method thereof for processing slot wedge loosening. The walking robot includes a vehicle body and a striking part, and the vehicle body is used for being adsorbed on an iron core of a stator and capable of moving relative to the stator. The striking part is disposed on the vehicle body and capable of moving in a radial direction of the stator relative to the vehicle body to pass through an insertion hole of a slot wedge. The striking part can also move in the axial direction of the stator relative to the vehicle body to strike a spacer within the insertion hole. The walking robot can directly enter the gap between the stator and a rotor and can move above a loose slot wedge. After the striking part is inserted into the insertion hole of the slot wedge, the striking part can strike the spacer along the axial direction of the stator to enable the spacer to move along the axial direction of the stator for a certain distance to realize tightening through expending in the slot wedge, thereby realizing an effect of fastening a coil. The loose slot wedge is processed through utilization of the walking robot to avoid waste of a lot of time and manpower caused by drawing through the rotor and handling of loosening by human power, thereby substantially raising the efficiency of inspection and repairing a motor.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a walking robot and a method for dealing with slot wedge loosening. Background technique [0002] The generator includes a stator and a rotor passing through the stator. The inner wall of the stator is covered with a coil. The generator is also provided with pads and slot wedges for pressing the coils. The pads are located between the coils and the slot wedges. After the generator has been running for a period of time, due to vibration, the block may move a certain distance relative to the slot wedge in the axial direction of the stator, causing the slot wedge to loosen, which will also cause the coil to loosen and affect the normal operation of the generator. When the staff overhauls the generator, they usually pull through the rotor first, then enter the stator bore, and test the slot wedges one by one. If the tested slot wedge is in a loose state, the staff will use tools ...
