Roller is arranged on by fixing axle at the concave spherical surface outlet edge of spring leaf.
In above technical scheme, fuse tube lower end is connected by dropout springboard with lower static contact, among dropout springboard with
The bottom plate for being fixedly mounted on porcelain vase lower end is hinged, and main spring and pair are installed respectively between dropout springboard both ends and bottom plate
Spring, main spring are fitted between dropout springboard upper surface and bottom plate lower surface, and auxiliary spring both ends are hooked in dropout and jumped respectively
In the dog hole of plate and bottom plate, in the extension mortar of the dropout springboard end of fuse tube lower end hanging sleeve.
In above technical scheme, hand is grabbed by shipping and reselling on another market installation on the robotic arm, is grabbed to install between mechanical arm in hand and is turned round
Spring.
The utility model has the advantages that the concave spherical surface outlet edge in upper static contact spring leaf sets rolling trip gear,
When closing a floodgate or opening a sluice gate, the spherical moving contact of fuse tube enters or left the concave spherical surface of spring leaf by pincushion roller, and reduction is opened a sluice gate
Thrust, achievable three-phase synchronous are opened a sluice gate, and avoid generation from opening a sluice gate hard arc and power network and equipment are caused damage.
