Abstract
The invention provides an overtravel measuring device for a transmission rod of a circuit breaker. The overtravel measuring device comprises a circuit breaker body and a transmission rod, wherein the transmission rod is arranged in the circuit breaker body; a transmission sleeve is fixedly sleeved on the transmission rod; an annular baffle plate is arranged at one end of the transmission sleeve; a spring and a sliding sleeve are sequentially arranged on the transmission sleeve; the transmission sleeve is levelled with the outer end of the sliding sleeve; two ends of the spring respectively prop against the annular baffle plate and the sliding sleeve; a transmission sleeve limiting baffle plate is arranged at the other end of the transmission rod; and the sliding sleeve is connected with a transmission crank arm of the circuit breaker body. The overtravel measuring device for the transmission rod of the circuit breaker has the advantages of scientific design, strong practicability, convenience in measurement and capability of quickly adjusting the travel of the transmission rod.
Description
Technical field
The present invention relates to a kind of outrange measurement mechanism, specifically, related to a kind of isolating switch drive link over travel measurement mechanism.
Background technology
For preventing switch-on trip of vacuum circuit breaker and keep certain contact pressure in "on" position that often the drive link at breaker operation mechanism arranges over travel protection structure.The problem that the vacuum circuit breaker spring overtravel structure of using at present exists the over travel distance to see and to touch, over travel is measured apart from being inconvenient to, and generally when measuring, needs to adopt special measuring tool, measure respectively combined floodgate stroke value and separating brake stroke value, then subtract each other and draw over travel numerical value.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, thereby a kind of design science, practical, the isolating switch drive link over travel measurement mechanism of measuring convenient and rapid adjustment drive link stroke are provided.
To achieve these goals, the technical solution adopted in the present invention is: a kind of isolating switch drive link over travel measurement mechanism, comprise breaker body and be arranged on the interior drive link of described breaker body, fixed cover is equipped with drive socket on the described drive link, one end of described drive socket is provided with ring baffle, be disposed with spring and sliding sleeve on the described drive socket, described drive socket is concordant with described sliding sleeve outer end, the two ends of described spring are pushed up respectively and are located on described ring baffle and the described sliding sleeve, the other end of described drive link is provided with the drive socket postive stop baffle, and described sliding sleeve is connected with the transmission crank arm of described breaker body.
Based on above-mentioned, the other end of described drive link is provided with stop nut, and described stop nut is arranged on the described drive socket postive stop baffle outside.
The relative prior art of the present invention has outstanding substantive distinguishing features and significant progressive, specifically, the present invention has increased drive socket at original isolating switch drive link, one end of described drive socket is provided with ring baffle, arrange on the described drive link and be disposed with spring and sliding sleeve on the drive socket, at drive link the drive socket postive stop baffle is set, when described transmission crank arm is closed a floodgate or disconnected lock when work, described transmission crank arm drives described sliding sleeve, described drive socket and described drive link, after finishing combined floodgate or disconnected lock work, described drive socket and described drive link stop motion, described transmission crank arm drives described sliding sleeve and continues motion, compress described spring, the distance that described sliding sleeve leaves described drive socket postive stop baffle is the over travel distance of this isolating switch; It has design science, practical, the advantage of measuring convenient and rapid adjustment drive link stroke.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of isolating switch drive link over travel measurement mechanism, comprise breaker body 1 and the drive link 11 that is arranged in the described breaker body 1, fixed cover is equipped with drive socket 2 on the described drive link 11, one end of described drive socket 2 is provided with ring baffle, be disposed with spring 21 and sliding sleeve 3 on the described drive socket 2, described drive socket 2 is concordant with described sliding sleeve 3 outer ends, the two ends of described spring 21 are pushed up respectively and are located on described ring baffle and the described sliding sleeve 3, the other end of described drive link 11 is provided with drive socket postive stop baffle 12, described sliding sleeve 3 is connected with the transmission crank arm 4 of described breaker body, the other end of described drive link 11 is provided with stop nut, and described stop nut is arranged on described drive socket postive stop baffle 12 outsides.
Based on above-mentioned, an end of described drive socket 2 is provided with ring baffle, and described ring baffle and described drive socket 2 can be one-body molded.
Based on above-mentioned, described drive socket 2 is bolted on the described drive link 11, the convenient relative position of adjusting between the two.
Based on above-mentioned, when breaker closing or separating brake, described transmission crank arm 4 drives described sliding sleeve 3, and described sliding sleeve 3 drives described drive socket 2 by spring 21, and then drives described drive link 11 motions, finishes breaker closing or separating brake.
Based on above-mentioned, when closing a floodgate or separating brake action when finishing, described drive link 11 and 2 stop motions of described drive socket, described transmission crank arm 4 drives described sliding sleeve 3 and continues motion, the described spring 21 of described sliding sleeve 3 compressions, the distance that this moment, described sliding sleeve 3 left described drive socket postive stop baffle 12 is the over travel distance of this isolating switch; Apart from the over travel distance of adjusting this isolating switch, open described stop nut according to this, then mobile described drive socket 2 is fixed by bolts to the adjustment of finishing the over travel distance on the described drive link 11 to correct position.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
