Technical Field
[0001] The utility model belongs to the technical direction of vertical pull rod fixers, and specifically relates to a vertical pull rod fixer. Background Art
[0002] The vertical pull rod is one of the important parts in the opening and closing process of the disconnector. The motor of the mechanism box drives the vertical connecting rod of the disconnector to rotate, and the vertical connecting rod is then transmitted to the interphase connecting rod on the frame to open and close the moving and static contacts of the knife switch, thereby realizing the opening and closing of the disconnector.
[0003] At present, the power output shaft of the motor is not directly connected to the vertical connecting rod by welding, but is connected by clamping the top of the motor output shaft and the tail end of the connecting rod. During the opening and closing operation, the vertical connecting rod and the clamp are prone to "slipping". When the motor power output shaft rotates, due to the slip between the vertical connecting rod and the clamp, the motor output power is normal, the output shaft rotates, but the vertical connecting rod does not rotate synchronously with the motor, and finally the knife switch is not opened and closed in place, or even cannot be opened and closed, posing a serious safety hazard. This phenomenon has become a problem that needs to be solved urgently by personnel in this field, so a vertical pull rod fixer is designed to suppress the slipping phenomenon, so that the vertical pull rod and the motor output shaft rotate synchronously, ensuring that the opening and closing are in place in one step.
