Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] combined with Figures 1 to 6 , a trip-proof vacuum circuit breaker electric chassis vehicle, including a static vehicle frame 1 and a moving vehicle frame 2 slidingly arranged on the static vehicle frame 1, and a front and rear screw 3 is horizontally arranged on the static vehicle frame 1, so that The front end of the screw 3 is fixed on the static frame 1; the moving frame 2 is fixed with a sliding sleeve 4, and the sliding sleeve 4 is screwed on the screw 3, so that the screw 3 rotates to drive the moving frame 2 Movement on the static frame 1; the end of the screw 3 is hinged with a tongue 5, and the lower end surface of the tongue 5 is limited on the moving frame 2, so that when the screw 3 rotates, the tongue 5 is relative to the moving frame 2 keep a fixed angle; it also includes a first runner 6, the first runner 6 is...

Abstract

The invention relates to a tripping-preventable vacuum circuit breaker electric chassis. The tripping-preventable vacuum circuit breaker electric chassis comprises a fixed frame and a moving frame which is slidingly arranged on the fixed frame; a screw rod drives the moving frame to move on the fixed frame; the tail end of the screw rod is hinged to a tongue sheet; the lower end surface of the tongue sheet is limited on the moving frame, so that the tongue sheet can maintain a fixed angle relative to the moving frame when the screw rod rotates; the tripping-preventable vacuum circuit breaker electric chassis further comprises a first rotation wheel and a second rotation wheel; the second rotation wheel rotates so as to drive a third pull rod hinged on a second connection lug to move, so that a switch S9 is pulled to move in a linkage manner; and the first rotation wheel rotates so as to drive a first pull rod hinged on a first connection lug to move, so that a switch S8 is pulled to move in a linkage manner. Based on the cushioning effect of the rotation wheels and the pull rods, the sensitivity of the switch S8 and the switch S9 switch to vibration is greatly reduced, and therefore, the stability of an automation system can be improved, and tripping situations can be greatly reduced.

Description

technical field [0001] The invention relates to an electric chassis vehicle for a vacuum circuit breaker. Background technique [0002] In order to make the mid-mounted vacuum circuit breaker more convenient to realize the automatic and intelligent remote control functions of pushing (pushing from the breaking position into the opening position and locking) and withdrawing (pushing from the passing position into the breaking position and locking) and intelligent remote control, an electric Chassis car, this kind of electric chassis car is equipped with a screw motor to drive the screw to rotate to drive the moving frame to separate or close relative to the static frame, so as to realize the push in and out of the vacuum circuit breaker. [0003] The S8 switch and the S9 switch are the most basic switches in the vacuum circuit breaker. The S8 switch and the S9 switch in the prior art are directly connected with the fittings on the screw by a hard connection structure, which m...
