Abstract
The utility model discloses a modified transmission structure between the chain wheel and driving wheel of high voltage breaker, wherein a transmission shaft is positioned on machine body; a driving wheel is fixedly sheathed on the transmission shaft; the periphery of the driving wheel is provided with an oblique tooth notch; a chain wheel is movably sheathed on the transmission shaft; one end of a pawl is rotationally and axially positioned on the chain wheel and the other end is abutted against the tooth notch; a positioning shaft is fixed on the machine body and can instantly contact and shift one end of the pawl when the high voltage vacuum breaker completes energy accumulation; therefore, when the pawl drives the driving wheel to contact the positioning shaft, the rotation of the chain wheel can make one end of the pawl be shifted by the positioning shaft and make the other end of the pawl off from the tooth notch to realize idle rotation with the driving wheel; after energy accumulation, when the pawl rotates along with the chain wheel to the positioning shaft, the pawl can be shifted by the positioning shaft all the time; after the accumulated energy is cleared, the tooth notch returns to initial position, and when the chain wheel drives the pawl to rotate to the tooth notch, the other end of the ratchet will be abutted against the tooth notch to drive the driving wheel to rotate again.
Description
Technical field
The utility model relates to a kind of high-pressure vacuum breaker, the driving structure improvement of particularly a kind of high-pressure vacuum breaker sprocket wheel and drive.
Background technology
Referring to Fig. 3, Fig. 4 and Fig. 5, the transmission of original high-pressure vacuum breaker sprocket wheel and drive realizes by following structure: power transmission shaft is rotatable to be positioned on the body, drive 3 fixed covers are located on the power transmission shaft 1, the drive peripheral radial has a groove, the drive two sides is respectively equipped with the identical bayonet socket of specification, two bayonet sockets communicate with groove and two bayonet sockets are positioned at groove within the drop shadow spread on drive two sides, be provided with an elastomer 7 in the groove, baffle plate 8 one end activities are arranged in the groove, described baffle plate one end both sides are respectively equipped with stuck point, but the proper stop of described stuck point is in the bayonet socket inwall, elastomer one end resilient abutment groove inwall, described baffle plate one end of elastomer other end resilient abutment, a side of the described baffle plate other end becomes the inclined-plane, and sprocket wheel 2 is movably set on the power transmission shaft, backing pin 9 axial restraints are positioned on the sprocket wheel, this backing pin just can be against non-inclined-plane one side of the baffle plate other end, when sprocket rotation to making backing pin just can be the time against the non-inclined-plane of baffle plate one side, backing pin drives drive and rotates; Locating shaft 6 is fixed on the body, locating piece 10 is movably set on the locating shaft, the locating piece other end just can be finished moment conflict drive surface in the high-pressure vacuum breaker energy storage, like this after backing pin drives drive with the rotation of sprocket wheel and turns to baffle plate inclined-plane one side contacts locating piece, the inclined-plane that locating piece prolongs the baffle plate other end is squeezed to baffle plate in the groove gradually: under the energy storage completion status, backing pin is passed on driving wheel periphery and drive continuing spinning; Back (being after the energy storage is made zero) baffle plate that closes a floodgate goes to initial position with drive, because elastomeric elastic force effect is ejected in the groove baffle plate other end, during the non-inclined-plane of backing pin conflict baffle plate one side, drives drive once more and rotates.
The drive mechanism number of spare parts of original sprocket wheel and drive is more, mechanism is comparatively complicated, and cost is higher, and because after the elastomer in the groove is subjected to the baffle plate extruding in the drive, Shi Erhui takes place that elastomer is stuck in the groove and the situation that baffle plate can't be ejected, and it is comparatively unreliable to use.
Summary of the invention
In order to remedy above deficiency, the utility model provides the driving structure improvement of a kind of high-pressure vacuum breaker sprocket wheel and drive, and this drive mechanism mechanism is simple, and cost is lower and use reliable.
The utility model for the technical scheme that solves its technical problem and adopt is:
The driving structure improvement of a kind of high-pressure vacuum breaker sprocket wheel and drive, comprise power transmission shaft, sprocket wheel and drive, power transmission shaft is rotatable to be positioned on the body, described drive is circular, the drive fixed cover is located on the power transmission shaft, the drive periphery forms an oblique teeth notch and forms ratchet, sprocket wheel is movably set on the power transmission shaft, be provided with a ratchet again, this ratchet one end rotatable shaft is to being positioned on the sprocket wheel, the ratchet other end just can prop up described teeth notch, and sprocket wheel can prop up described teeth notch by the ratchet other end and drive the drive rotation like this; Be provided with a locating shaft again, this locating shaft is fixed on the body, this locating shaft just can be finished the moment conflict and stir ratchet one end in the high-pressure vacuum breaker energy storage, when ratchet drives drive and goes to lucky conflict locating shaft like this (the lucky energy storage of vacuum circuit-breaker this moment is finished), the rotation of sprocket wheel impel ratchet one end be positioned the axle stir, the ratchet other end dallies with drive thereupon breaking away from described teeth notch: under the energy storage completion status, the ratchet axle that always is positioned during to locating shaft with sprocket rotation is stirred and is become disengaged position with the teeth notch, i.e. ratchet dallies with drive all the time under the energy storage completion status; Behind the vacuum breaker closing (being after energy storage is made zero), the teeth notch is returned to initial position, and when sprocket wheel drive ratchet went to the teeth notch, the ratchet other end just can prop up the teeth notch and drive the drive rotation once more like this.
The beneficial effects of the utility model are: drive of the present utility model forms the ratchet that contains a teeth notch, the ratchet rotatable shaft is to being positioned on the sprocket wheel, adopt ratchet and pawl arrangement to realize the transmission of sprocket wheel and drive, use reliably, simple in structure and cost is lower.
