Abstract
The utility model provides a breaker transmission rod over stroke measuring device which comprises a breaker body and a transmission rod arranged in the breaker body. The transmission rod is fixedly sleeved with a transmission sleeve. One end of the transmission sleeve is provided with an annular baffle plate. The transmission sleeve is orderly provided with a spring and a sliding sleeve. The transmission sleeve is aligned with an outer end part of the sliding sleeve. Two ends of the spring press the annular baffle plate and the sliding sleeve respectively. Another end of the transmission rod is provided with a transmission sleeve limit baffle plate. The sliding sleeve is connected with a transmission turn arm of the breaker body. The breaker transmission rod over stroke measuring device has the advantages of scientific design, strong practicability, convenient measurement and rapid adjustment of a transmission rod stroke.
Description
Technical field
The utility model relates to a kind of outrange measurement mechanism, specifically, has 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 purpose of this utility model 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 scheme that the utility model adopts 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 utility model has substantive distinguishing features and progress, specifically, the utility model 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 utility model.
Embodiment
Below by embodiment, the technical solution of the utility model 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 the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model 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 embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
