Abstract
The utility model relates to a vacuum circuit breaker, particularly a crank connecting rod type operating mechanism. The utility model is composed of a motor and a driving mechanism, wherein, one end of a crank is fixedly connected with a rotating shaft and the other end is hinged with a connecting rod in the driving mechanism the other end of the connecting rod is hinged with a swinging rod; the other end of the swinging rod is sheathed on a shaft sleeve; a ratchet pawl is connected with the middle part of the swinging rod; the ratchet pawl is matched with a ratchet wheel; the ratchet wheel can be connected with the rotating shaft of the breaker. The utility model has the advantages of long force arm, low energy consumption, smooth operation, low noise, etc.
Description
The utility model relates to air circuit, specifically a kind of link-type operating mechanism.
Motor-operating mechanism on the air circuit mainly is used as the electric switch-on energy storage device of circuit breaker, original mechanism adopts cam directly to promote ratchet and makes reciprocating cutter, so the arm of force is less, during work, need to drive with bigger power, energy consumption is than higher comparatively speaking, simultaneously during cam drive, because of speed very fast, noise can take place unavoidably, influence environment, in addition, the cam-type structure takes up space bigger.
The purpose of this utility model is that design is a kind of rational in infrastructure, the reliable electric operating mechanism of circuit-breaker of stable action.
The measure of being taked is to utilize the driving mechanism of a toggle as this operating mechanism for achieving the above object, wherein an end and the rotating shaft of crank are affixed, the other end and rod hinge connection, the other end and the fork of connecting rod are hinged, the other end of fork be enclosed within the concentric axle sleeve of ratchet on, connect a ratchet at the middle part of fork, this ratchet cooperates with tooth on the ratchet, ratchet can be connected with breaker rotating axis, for avoiding the ratchet reversing, on near the support the ratchet, utilize bearing pin that one retaining ratchet is installed, this retaining ratchet cooperates with ratchet.
The utility model has the advantages that owing to adopt toggle as driving mechanism, compare with original cam mechanism, increased power arm, under the constant prerequisite of identical resistance condition and total energy storage power, can significantly reduce the power output of motor, thus can energy savings; Secondly, the rotating speed of crank is less in this device, makes the entire mechanism running more steady, ratchet also greatly reduces the impulsive force of ratchet, makes the entire mechanism life-span long, and noise is little, in addition, this device takes up space less, makes dwindling of whole circuit breaker volume become possibility.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
As shown in the figure; Output at motor 5 connects gearbox 13, one end of crank 8 is fixed on the output revolving shaft 15 of gearbox, the other end of crank and connecting rod 7 are hinged, the other end of connecting rod utilizes bearing pin 14 and fork 6 to be hinged, utilize bearing pin 12 to connect a ratchet 4 at the middle part of fork, the other end of fork be enclosed within the concentric axle sleeve of ratchet 3 on, ratchet 3 is connected with breaker rotating axis 2, for avoiding the ratchet counter-rotating, utilize bearing pin to be connected retaining ratchet 1 with spring near the support the ratchet, ratchet 4 cooperates with ratchet respectively with 1.10 is block among the figure, and 11 is axle.
During work, motor is pressed the certain orientation rotation, drives crank by reduction gearing, drives fork by connecting rod again and swings back and forth by certain angle, drive the ratchet motion during fork swing, the every swing of fork once, ratchet just drives ratchet and turns over certain angle, simultaneously, the retaining ratchet prevents the ratchet counter-rotating, when ratchet rotates, just drive the breaker rotating axis rotation simultaneously, thereby reach the purpose of energy storage.
