Special trolley for replacing current transformer of armored switch cabinet

Abstract

The invention discloses a special trolley for replacing a current transformer of an armored switch cabinet. The trolley comprises a device frame body, a moving system, a supporting system and a lifting system, wherein stand columns are fixedly arranged at the two sides of the front end of a bottom frame correspondingly, the tops of the two stand columns are connected through a chain fixing plate,a transportation handle is fixedly arranged at the top of the rear end of the bottom frame, and anti-overturning components are arranged at the two sides of the bottom frame correspondingly; transportation rear wheels are arranged at the two sides of the bottom of the rear end of the bottom frame, and pulley brakes are arranged on the transportation rear wheels; and the supporting system comprisesa stepped transition platform fixedly connected to a sliding plate, a connecting rod is rotationally connected to the front end of the stepped transition platform through a vertically-arranged firstrotating shaft, a supporting platform is fixed to the end of the connecting rod, a motor is fixed to the position, located at one side of the connecting rod, of the stepped transition platform, the motor is connected to the fixed end of an electric telescopic rod, and the extending end of the electric telescopic rod is rotationally connected to the connecting rod through a second rotating shaft. Through the rotary supporting system and the lifting system, the movement in the horizontal direction and the vertical direction can be automatically achieved.

Description

technical field [0001] The invention relates to the technical field of tools for replacing current transformers in armored switch cabinets, in particular to a special trolley for replacing current transformers in armored switch cabinets. Background technique [0002] At present, the traditional current transformer replacement tool cannot realize the lifting function and simultaneously rotate and move in the horizontal direction, and the flexibility is poor. The entire construction work takes a long time, and the corresponding power outage time is relatively long, which does not meet the current requirements for improving power supply reliability and improving customers' sense of gain in power usage. Therefore, the efficiency of construction work is low, the required power outage time is long, and the reliability requirements of power supply cannot be guaranteed. [0003] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides a...
