High-voltage coil operating platform

Abstract

The invention discloses a high-voltage coil operating platform. The high-voltage coil operating platform is characterized in that supporting devices which are composed of supporting frames and top beams are arranged at the upper front end and upper rear end of a quadrate bottom plate, wherein a motor case is embedded into the middle part of each top beam, and a double-axis AC motor is arranged inthe middle part of an inner chamber of the motor case, and steel ropes coil rotors of the double-axis AC motors; locking devices are arranged at the tail ends of the rotors of the double-axis AC motors; a motor switch is arranged upper right of the top beam at the front side; a bearing plate is arranged between the front supporting device and the rear supporting device, and the bearing plate is connected to the steel wire ropes through pulling blocks; spring pulley devices are fixed to the parts, close to the supporting frames, of the quadrate bearing plates through bolts; and wheels are fixedbelow a bottom plate through screws. The high-voltage coil operating platform has the beneficial effects that the bearing plate can up and down move smoothly through the spring pulley devices, and the frictional force between the bearing plates and the supporting frames can be extremely reduced; and harsh noise produced by the bearing plates moving up and down can be avoided.

Description

technical field [0001] The invention relates to the field of special equipment for electricians, in particular to a high-voltage coil operating platform. Background technique [0002] When the electrical industry produces large and medium-sized transformers and high-voltage transformers, the coils that have been wound are placed vertically, and manual operations are required when inserting the original iron core and insulation elements on it. Since the height of the coil is about 3 femtometers, workers need to use a liftable operating platform to complete the work. [0003] In the past similar operating platforms, the platform is rigidly connected to the four-corner columns through the platform lifting mechanism, and the motor drives the screw lifting mechanism to perform lifting movements to realize the lifting function of the platform. [0004] Since the four corners of this structure are all rigidly connected, over-positioning is serious, resulting in many insurmountable...

AI Technical Summary

Problems solved by technology

[0006] The difficulty of manufacturing increases the production cost of equipment;

[0007] 2) The resistance of platform lifting increases, which needs to be solved by increasing the power of the motor;

[0008] 3) The lead screw of the helical transmission pair driven up and down by the four corners of the platform is prone to mechanical vibration, thereby reducing the vibration of the helical transmission pair.

[0010] 4) During the lifting process of the platform, the whole platform will generate strong vibration and noise
