Vacuum arc-extinguishing chamber transfer conveying disc with limiting function fulfilled via abutment by elevating rotary cam

Abstract

The invention discloses a vacuum arc-extinguishing chamber transfer conveying disc with a limiting function fulfilled via abutment by an elevating rotary cam. The vacuum arc-extinguishing chamber transfer conveying disc comprises a transfer base disc; a middle portion of an upper end face of the transfer base disc is provided with a clamping device; the clamping device comprises a toothed ring, aplurality of circumferentially and evenly distributed toothed wheels and a plurality of threaded support rods; the toothed ring is pivoted on the upper end face of the transfer base disc, the toothedwheels are arranged in the toothed ring and are pivoted on the upper end face of the transfer base disc, the toothed wheels are engaged with the toothed ring, and a threaded hole that penetrates up and down is formed at a center of each toothed wheel; a threaded hole that penetrates up and down is formed at a part, positioned below the threaded hole of each toothed wheel, of the upper end face ofthe transfer base disc; a screw thread support rod runs through the toothed wheels and the transfer base disc and is connected onto the toothed wheels and the transfer base disc in a screwed manner; alimiting scam is fixed on an upper end face of the screw thread support rod. The vacuum arc-extinguishing chamber transfer conveying disc is simple in structure and convenient in operation and is suitable for vacuum arc-extinguishing chambers of different specifications, types of transfer conveying discs can be reduced, production costs can be reduced, economic benefits can be improved, and dailymanagement can be facilitated.

Description

technical field [0001] The invention relates to the detection technical field of a vacuum interrupter, in particular to a vacuum interrupter transfer and conveying tray with a lifting rotary cam abutting against a limit position. Background technique [0002] The vacuum interrupter is the core component of the medium and high voltage power switch. It has a wide variety of specifications. At present, most of the transfer trays of the vacuum interrupter transmission line are non-adjustable, which requires each interrupter to be equipped with a transfer tray. As a result, there are many kinds of transfer trays and difficulties in daily management. [0003] Therefore, it has become an urgent problem to be solved by people in the industry to develop a transfer transport tray that can be adapted to different specifications of the interrupter. Contents of the invention [0004] The purpose of the present invention is to address the deficiencies in the prior art, and provide a va...
