Problems solved by technology

The current technology mostly adopts a horizontal extraction mechanism, and the operator operates horizontally in the front. In order to have sufficient horizontal depth to complete the extraction and push actions, the switch cabinet attachment requires longitudinal depth, especially in medium and high voltage switch cabinets. The withdrawable structure makes the longitudinal depth of the high-voltage switchgear larger and increases the volume of the cabinet

Abstract

The invention discloses an elevating linkage type drive device comprising a bracket with a vertical beam arranged in the middle, elevation mechanisms arranged at the two sides of the vertical beam of the bracket, and locking mechanisms for locking lower ends of two support arms tightly to prevent separation. Translation drive mechanisms include linkage pins, fan-shaped gear wheels, and racks; each linkage pin is fixedly arranged at one side of each carrying plate and extends horizontally; the fan-shaped gear wheels fixedly arranged at the bracket in a rotatable manner are provided with guiding slots matching the linkage pins; and the racks are engaged with the fan-shaped gear wheels and are fixedly connected with to-be-driven translation parts. According to the invention, actuator mechanisms are arranged at the liftable carrying plates, so that the height space is utilized fully and the actuating mechanisms are simplified. Moreover, with linkage of the elevation mechanisms and the translation drive mechanisms, synchronous driving of the to-be-driven translation parts is realized, so that overall designing can be realized conveniently and the usage security can be improved.

Description

technical field [0001] The invention relates to the technical field of dual-power switch equipment and a switch cabinet thereof, in particular to a lifting linkage driving device and a control method. Background technique [0002] In the known field of power distribution technology, the withdrawable mechanism has been widely used due to its characteristics of easy operation, convenient maintenance and replacement. The current technology mostly adopts a horizontal extraction mechanism, and the operator operates horizontally in front of the operator. In order to have sufficient horizontal depth to complete the extraction and push actions, the switch cabinet attachment requires longitudinal depth, especially in medium and high voltage switch cabinets. The extraction structure makes the longitudinal depth of the high-voltage switchgear larger and increases the volume of the cabinet. [0003] Now, the space required for power supply is getting smaller and smaller, but the load o...
