Abstract
The automatic limiting device for worm-gear propelling mechanism is a new type of propelling mechanism with movable parts in high-voltage switch equipment, and is rotated by means of worm-gear to drive pin, shifting plate, stopping wheel and tension spring to extend and reset so as to implement the propelling and automatic locking of mechanism. The device can accurately control the insertion depth and the contact area of the moving contact, ensures the use performance of the movable high-voltage switch equipment, can avoid the damage of a worm gear pair in the device, and brings convenience to the use and maintenance of a user.
Description
The utility model relates to a kind of automatic spacing device that is installed in the worm and gear propulsive mechanism on the withdraw-type high voltage switchgear.
In the withdraw-type high voltage switchgear, owing to advance the insertion depth of a moving contact of handcart in certain scope, could guarantee the performance of its high voltage switchgear.Do not have a kind of propulsive mechanism interlocking stopping means in the past, guaranteed to remove the propelling stroke of parts.
The utility model purpose is: a kind of worm and gear stopping means with stopping wheel, scotch that designs at solve going up problem just.
Accompanying drawing one of the present utility model is the front view of propulsive mechanism, accompanying drawing two is the end view of propulsive mechanism, it comprises stopping wheel 1, scotch 2 and dials plate 7 etc., its feature is put worm screw 5 external parts at stopping wheel 1, one scotch 2 is arranged under it, be fixed on the support by axle in the middle of the scotch 2, the lower end connects returning pull-spring 3 and dials plate 7, dials plate 7 and stretches out the pin 8 of putting worm gear 6 or sell 9 places.
Worm and gear propulsive mechanism automatic spacing device is installed in and can removes on the parts, and when propulsive mechanism during at initial position, stopping wheel 1, scotch 2 are in latched position, and extension spring 3 is extended, and connecting lever 4 is in the below at propulsive mechanism center; When rotary worm 5, worm gear 6, drive pin 8 and leave group plate 7, extension spring 3 this moment makes group plate 7 and scotch 2 change the position, but propulsive mechanism is in advanced state, and connecting lever 4 is in the top at propulsive mechanism center; When being rotated further worm screw 5, worm gear 6, pin 9 drives dials plate 7 and scotch 2, makes stopping wheel 1 and scotch 2 be in latched position again, and extension spring 3 is extended, and connecting lever 4 is in the below at propulsive mechanism center, has finished the propelling stroke that can remove parts.
This utility model is easy to use, reliable, rational in infrastructure, novel, not only can make moving contact insertion depth and contact area reach the regulation requirement, to guarantee the serviceability of high voltage switchgear, this device automatically locks owing to two extreme positions simultaneously, can avoid the damage of worm gear, for the user uses and maintenance brings convenience.
