Abstract
The invention discloses an improved switching-off part structure of a high-voltage vacuum breaker. One end of a first connecting plate is fixedly sheathed on a tripping semiaxis, and the other end of the first connecting plate is pivoted with a push plate; a pinch plate is sheathed on a fixed axis, one end of the pinch plate can just push against the tripping semiaxis, and the other end of the pinch plate is pivoted with one end of a second connecting plate; a crank arm is fixedly sheathed on a main axis, and one end of the crank arm is elastically pushed against the other end of the second connecting plate all the time; the tripping semiaxis, the fixed axis and the main axis can be positioned on the engine body in a rotating mode so as to push the push plate; the tripping semiaxis is caused to rotate by the first connecting plate, one end of the pinch plate is disconnected with the tripping semiaxis to swing downwards, and the other end of the pinch plate drives the second connecting plate to swing upwards therewith; as one end of the crank arm is elastically pushed against the other end of the second connecting plate all the time, one end of the crank arm swings upwards therewith so as to drive the main axis to rotate to finish the action of switching off. The invention needs lower switching-off tripping force (thrust needed by the push plate); the contact area of the second connecting plate and the crank arm is large, so that the second connecting plate and the crank arm have small possibility of slipping, and the reliability is relatively higher.
Description
Technical field
The present invention relates to a kind of high-pressure vacuum breaker, particularly a kind of separating brake portion structure-improved of high-pressure vacuum breaker.
Background technology
Referring to Fig. 2, the action of the separating brake of original high-pressure vacuum breaker realizes through following structure: bent plate 8 fixed covers are located on the dropout semiaxis 1, set firmly a release lever 9 on the bent plate; The buckle 2 one ends dropout semiaxis of just can conflicting, the buckle other end and second connecting plate, 7 one end fixed covers are located on the locating shaft 10, and the second connecting plate other end and the 3rd connecting plate 11 1 ends articulate; The connecting lever fixed cover is located on the main shaft 4; Connecting lever 3 one ends are elasticity the 3rd connecting plate other end of conflicting all the time, and dropout semiaxis, locating shaft and main shaft are rotatable to be positioned on the body, through stirring release lever the dropout semiaxis is rotated like this; Buckle one end breaks away from the dropout semiaxis and upwards swings and make the locating shaft rotation; The rotation of locating shaft makes the second connecting plate other end drive the upwards swing of the 3rd connecting plate, because connecting lever one end elasticity the 3rd connecting plate other end of conflicting all the time, connecting lever one end is upwards swing thereupon; Rotate thereby drive main shaft, accomplish the separating brake action with this.
The separating brake portion of this high-pressure vacuum breaker stirs through release lever and drives the rotation of dropout semiaxis, and its required tripping force (power of stirring that the dropout plate is required) is bigger; Contact area between the 3rd connecting plate and the connecting lever is less, skids easily, and reliability is relatively poor relatively.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of separating brake portion structure-improved of high-pressure vacuum breaker, the required brake-separating and tripping force of this separating brake portion is less, and reliability is higher.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of separating brake portion structure-improved of high-pressure vacuum breaker comprises dropout semiaxis, buckle, connecting lever and main shaft, and first connecting plate, one end fixed cover is located on the dropout semiaxis; The first connecting plate other end and push pedal one end articulate, and buckle is sheathed on the locating shaft, the buckle one end dropout semiaxis of just can conflicting; The buckle other end and second connecting plate, one end articulate, and the connecting lever fixed cover is located on the main shaft, and connecting lever one end is the elasticity second connecting plate other end of conflicting all the time; Dropout semiaxis, locating shaft and main shaft are rotatable to be positioned on the body, promotes push pedal like this, through first connecting plate dropout semiaxis is rotated; Buckle one end breaks away from the dropout semiaxis to lower swing, and the buckle other end drives the upwards swing thereupon of second connecting plate, because the connecting lever one end elasticity second connecting plate other end of conflicting all the time; Connecting lever one end is upwards swing thereupon, rotates thereby drive main shaft, accomplishes the separating brake action with this; Connecting lever one end forms crotch, and the second connecting plate other end just blocks stop in this crotch inwall, can prevent like this to skid between second connecting plate and connecting lever, and reliability is high.
Buckle is movably set on the locating shaft, drives locating shaft during the buckle swing and rotates.
The buckle fixed cover is located on the locating shaft, can not drive locating shaft during the buckle swing and rotate.
Useful technique effect of the present invention is: the present invention adopts push pedal to promote the structure that first connecting plate rotates the dropout semiaxis, and required brake-separating and tripping force (thrust that push pedal is required) is lower; Contact area between second connecting plate and the connecting lever is bigger, is difficult for skidding, and reliability is higher relatively.

Fig. 2 is the original technological sketch map that contrasts with the present invention.
Embodiment
Embodiment: a kind of separating brake portion structure-improved of high-pressure vacuum breaker comprises that dropout semiaxis 1, buckle 2, connecting lever 3 and main shaft 4, the first connecting plates 5 one end fixed covers are located on the dropout semiaxis 1; First connecting plate, 5 other ends and push pedal 6 one ends articulate, and buckle 2 is sheathed on the locating shaft 10, the buckle 2 one ends dropout semiaxis 1 of just can conflicting; Buckle 2 other ends and second connecting plate, 7 one ends articulate, and connecting lever 3 fixed covers are located on the main shaft 4, and connecting lever 3 one ends are elasticity second connecting plate, 7 other ends of conflicting all the time; Dropout semiaxis 1, locating shaft 14 and main shaft 4 rotatable being positioned on the body promote push pedal 6 like this, through first connecting plate 5 dropout semiaxis 1 are rotated; Buckle 2 one ends break away from dropout semiaxis 1 to lower swing; Buckle 2 other ends drive the upwards swing thereupon of second connecting plate 7, because connecting lever 3 one ends elasticity second connecting plate, 7 other ends of conflicting all the time, connecting lever 3 one ends are upwards swing thereupon; Rotate thereby drive main shaft 4, accomplish the separating brake action with this;
Connecting lever 3 one ends form crotch 12, the second connecting plates 7 other ends and just block stop in these crotch 12 inwalls, can prevent that like this 3 of second connecting plate 7 and connecting levers from skidding, and reliability is high.
