Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
Embodiment:
As Figure 1-3, a kind of clamping device installed for vacuum circuit breaker polar, comprise substrate 1, substrate 1 is rectangle, and its length and vacuum circuit-breaker adapt, and substrate 1 comprises the front installed surface and rear installed surface that are parallel to each other; The two ends of front installed surface are respectively provided with a clamping limb 2, two clamping limbs 2 and can do in opposite directions or contrary movement based on front installed surface; Rear installed surface is provided with the motor of driving two clamping limbs 2 movement; Front installed surface two ends are respectively provided with one for detecting the exploring block 3 of clamping limb 2, and exploring block 3 is in the outside of two clamping limbs 2.
Substrate 1 can be understood as a face wall, and its front installed surface and rear installed surface can install parts.The equipment connection that substrate itself also can be installed with other pole, but this is not content of the present utility model, so will not describe.
Two clamping limbs 2 can do in opposite directions or contrary movement based on front installed surface, and this is exactly the action clamping or unclamp vacuum circuit-breaker in fact.
The effect of exploring block 3 is that after ensureing that clamping limb arrives the extreme position at two ends, motor or cylinder stop driving.
Exploring block 3 meeting and control assembly, as the connection such as electromagnetically operated valve, PLC, these are all that those skilled in the art are accessible, are not described further.
After clamping vacuum circuit-breaker, also need to allow motor stop, the control mode of transducer can be adopted, also according to the different vacuum circuit-breaker models setting motor rotation time etc., can not be content of the present utility model, be not described further.
Wherein, front installed surface is provided with the power transmission shaft 4 of level, and the two ends of power transmission shaft are processed with the transmission external screw thread 41 of preset length, and the externally threaded rotation direction of the transmission at two ends is contrary, and clamping limb is provided with the screwed hole matched with transmission external screw thread; Rear installed surface is provided with drive motors 5, and the output shaft of drive motors is connected with power transmission shaft, and can drive drive axis.
Transmission external screw thread coordinates with screwed hole, just when drive axis, can drive clamping limb motion.
The externally threaded rotation direction of transmission at two ends is contrary, just can make two clamping limbs do based on front installed surface in opposite directions or contrary movement, namely clamp or unclamp the action of vacuum circuit-breaker.
