Lifting dual power supply device with mechanical interlock

Abstract

The invention discloses an elevating type double-power-source supply device with mechanical interlocking. The elevating type double-power-source supply device comprises a bracket with a vertical beam arranged in the middle, elevation mechanisms arranged at two sides of the vertical beam of the bracket, and two groups of mechanical interlocking mechanisms. Limiting parts or are arranged at the two sides or end portions of carrying plates; and the rear side surfaces of the limiting parts are inclined surfaces with upper sides protruding forwardly. Abutting parts matching the limiting parts are formed at a handcart; the front side surfaces of the abutting parts are slope surfaces corresponding to the inclined surfaces. The limiting parts are connected directly with ground points of the elevation mechanisms by wires. According to the elevating type double-power-source supply device disclosed by 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. The mechanical interlocking mechanisms with high adaptability are independent of the actuator mechanism and can be loaded at different kinds of actuator mechanisms. With interlocking mechanisms like a gear and rack transmission mechanism, rotation of a spindle of one actuator mechanism is transformed into driving to a top rod and thus closing of the actuator mechanism at one side drives the top rod to be inserted into the space between transmission gear wheels inside another actuator mechanism and to be clamped tightly, so that the actuator mechanism at the other side can not carry out closing.

Description

technical field [0001] The invention relates to the technical field of dual-power switching equipment and a switchgear thereof, in particular to a lifting type dual-power supply device with mechanical interlocking. 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, ...

AI Technical Summary

Problems solved by technology

[0004] And in the prior art, the interlocking mechanism generally adopts the same rotating shaft to operate, so one of the two mechanical interlocking arms breaks down, causing the entire interlocking to fail, and the reliability is poor. In addition, the entire mechanical interlocking mechanism and the product form an integral body, causing installation, maintenance and other problems. Inconvenient, and the grounding protection of the existing power supply equipment is poor
