The utility model comprises a motor, an electrical interlocking over-travel-limit switch and a rocker which are both symmetrically arranged on a fixed plate, a cam rotating disc, a locating piece, and a drive shaft, and is characterized in that the rocker is mounted on the locating piece, the locating piece and the motor are mounted on the fixed plate, the drive shaft is connected with the cam rotating disc which is formed by symmetrical action planes and is of pomfret shape, and a guide post is arranged on the rocker and is engaged and transmitted with the action planes which are arranged on the cam rotating disc. The utility model adopts the symmetrical design of the cam rotating disc, which solves the defect that because the rotating angles of the motor are larger in the original cam transmission structure, the switching time is longer between the major and the spare power supply circuit-breakers, thereby the whole performances and the service lives of the duplicate-supply automatic diverter switch are largely enhanced, and the market has a good prospect.
Description
Technical field
The utility model relates to the improvement of the mechanical interlocking transmission device of double power supply automatic switching switch, especially to the improvement of the mechanical interlocking transmission device cam drive mechanism of double power supply automatic switching switch.
Background technology
Produce at present, sell, the cam drive structure of mechanical interlocking transmission device in the double power supply automatic switching switch that uses, take guide pillar and the location hole fit structure on the rocking bar on the cam to realize main, auxiliaries-supply circuit-breaker separating brake and combined floodgate, as ZL00203798, though it is excessive and cost is high that this patent structure has solved former double power supply automatic switching switch volume, defectives such as complex structure, but also exist main, switching time between the auxiliaries-supply circuit-breaker is long and behind a breaker open operation and another breaker closing, the handle of circuit breaker all is in the defective of tensioned state, cause the spring easy damaged in the circuit breaker, useful life is short.
Summary of the invention
In view of the deficiency that prior art exists, the purpose of this utility model aims to provide the mechanical interlocking transmission device of the double power supply automatic switching switch that a kind of motor anglec of rotation is little, switch speed is fast.
Another purpose of the present utility model aims to provide a kind of operating mechanism of eliminating behind the breaker open operation to the mechanical interlocking transmission device of the double power supply automatic switching switch of handle compressing.
The utility model is finished as follows: the utility model comprises motor, be symmetricly set on electrical interlock travel switch on the fixed head and rocking bar, cam turntable, keeper, power transmission shaft, fixed head, described rocking bar is installed on the keeper, described keeper, motor are installed on the fixed head, described power transmission shaft is connected with cam turntable, described cam turntable is made up of the acting surface of symmetry, be provided with guide pillar on described rocking bar, this guide pillar cooperates transmission with acting surface on the cam turntable.
The symmetrical acting surface of above-mentioned cam turntable is made up of the upper and lower acting surface and the convex surface of groove, and its shape is prosperous fish shape.
The utility model compared with prior art, simple and ingenious structure, easy to process, the motor rotational angle dwindles when switching between the primary, spare power circuit breaker, service speed is fast, and cost is low, has improved the overall performance and the useful life of whole double power supply automatic switching switch greatly.

Embodiment
Accompanying drawing has been represented structure of the present utility model, in conjunction with the embodiments structure of the present utility model and principle thereof is further elaborated below again.Double power supply automatic switching switch is made up of the circuit breaker of two band annexes, the mechanical interlocking transmission device and controller three parts of the single drive of motor of a cover.Described mechanical interlocking transmission device comprises motor 1, is symmetricly set on electrical interlock travel switch 2 and rocking bar 3, cam turntable 4, keeper 5, power transmission shaft 7 on the fixed head 8, described rocking bar 3 is installed on the keeper 5, described keeper 5, motor 1 are installed on the fixed head 8, described power transmission shaft 7 is connected with cam turntable 4, described cam turntable 4 is made up of the acting surface of symmetry, be provided with guide pillar on described rocking bar 3, this guide pillar cooperates transmission with acting surface on the cam turntable 4.The symmetrical acting surface of described cam turntable is made up of the upper and lower acting surface 6,9 and the convex surface 11 of groove, and its shape is prosperous fish shape.Described guide pillar 10 is for being equipped with the guide pillar of ball bearing, to reduce the friction in the transmission.Thereby double power supply automatic switching switch cooperates transmission to drive rocking bar 3 rotations by the symmetrical acting surface on the cam turntable of prosperous fish shape with guide pillar, make circuit breaker be in button, separating brake, three kinds of different conditions of combined floodgate again.Adopt the design symmetry of cam turntable that the motor rotational angle is dwindled in the utility model, thereby shorten dramatically the switching time that reaches between the primary, spare power circuit breaker, simultaneously behind a breaker closing, rotation along with cam turntable 4, guide pillar on the rocking bar moves up to breaker open operation at following acting surface 9, when arriving peak, circuit breaker is in the state of detaining again, cam turntable 4 further rotates, guide pillar reduces gradually, make the handle of circuit breaker be in relaxation state, improved the useful life of circuit breaker greatly.How finishing circuit breaker in conjunction with concrete accompanying drawing sets forth in detail the utility model more below is in separating brake, combined floodgate respectively, buckles three kinds of different conditions again.
(1) as shown in Figure 2, when cam turntable 4 is rotated counterclockwise, the last acting surface of cam turntable 4 left side grooves drives left side rocking bar 3 by guide pillar 10 and is rotated down, finish the "on" position of primary power cource circuit breaker, convex surface and the right rocking bar 3 on cam turntable 4 the right contact simultaneously, make auxiliaries-supply circuit-breaker keep gate-dividing state; Finish interlocking by rotating disk 4 the right convex shapes, make auxiliaries-supply circuit-breaker can not be in the state (as shown in Figure 3) of combined floodgate again.
(2) when cam turntable 4 turns clockwise, the following acting surface of cam turntable 4 left side grooves drives left side rocking bar 3, finish the gate-dividing state of power circuit breaker commonly used, following acting surface and the right rocking bar 3 of cam turntable 4 the right grooves contact simultaneously, make auxiliaries-supply circuit-breaker keep gate-dividing state; Two following acting surfaces by cam turntable 4 left and right both sides grooves are finished interlocking, make primary, spare power circuit breaker can not be in the state (as shown in Figure 4) that closes a floodgate simultaneously again.
(3) when cam turntable 4 continues to turn clockwise, the last acting surface of cam turntable 4 the right grooves drives the right rocking bar 3 by guide pillar 10 and is rotated down, and finishes the "on" position of auxiliaries-supply circuit-breaker; At this moment cam turntable 4 is finished interlocking by the convex shape on the left side, makes the primary power cource circuit breaker can not be in the state (as shown in Figure 5) of combined floodgate again.
(4) be in the combined floodgate power supply state when a circuit breaker, when causing the dropout tripping operation because of the line fault face, the convex surface of cam turntable 4 clockwise or rotate counterclockwise with rocking bar on guide pillar main or back-up breaker detained when forming peak again and reset, then cam turntable 4 counterclockwise or clockwise rotate, the guide pillar on the last acting surface drive rocking bar closes a floodgate (as shown in Figure 6) to circuit breaker.
