Description
Technical field
This utility model relates to medium-voltage distribution technical field, is specifically related to a kind of valve driving device.
Background technology
Valve mechanism is one safety insulating device in switch cubicle, and the structure of valve mechanism generally comprises valve plate, and valve closes mechanism, valve driving device etc..
When can the switching on/off handcart of withdraw-type be in normal operating condition time, connected by loop, valve opens wide.When needs power-off or when keeping in repair, for support personnel's safety, former unlimited valve need to be closed, charged major loop static contact is isolated from the outside.Retreat to now by switching on/off handcart outside testing position or switch cubicle, depart from certain distance with the static contact on major loop, reach valve and close purpose.
Currently for specific switch cubicle, still following the mode that chain pulls upper and lower valve plate to open, due to chain can not back transfer thrust, so valve be only capable of rely on self-weight reset, directly result in valve heaviness, and there is unstability.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of safe and reliable Novel valve driving device.For this, this utility model provides techniques below scheme:
A kind of valve driving device, including bearing, switching on/off handcart, shift fork, first connecting rod, second connecting rod and turn shoulder bar, described first connecting rod one end is rotatably connected on bearing, the other end is hinged with one end of second connecting rod, the other end of described second connecting rod is hinged with shift fork, and described shift fork bottom and the one end turning shoulder bar are connected；Described bearing is provided with chute, and switching on/off handcart promotes the shift fork can first connecting rod, second connecting rod and turn shoulder bar and rotate to working position from test position in chute.
Adopting on the basis of technique scheme, this utility model also can adopt technical scheme further below:
Described bearing is arranged over spacing roller bearing at chute, moves spacing for switching on/off handcart, can prevent switching on/off handcart from offsetting up under reaction force acts upwards.
Described first connecting rod and described in turn shoulder bar opposite direction rotating.
Multiple described spacing roller bearings are mounted equidistant.
Described shift fork is Y shape shift fork.
Owing to adopting the technical solution of the utility model, the beneficial effects of the utility model are: this utility model device, simple in construction, and stability is high, it is easy to assemble.This utility model compares chain-type self-weight reset, is rotated up to working position or test position by quadric chain, and simple to operate, sensitivity and stability are all greatly improved.

Detailed description of the invention
As shown in the figure, a kind of valve driving device, including bearing 4, switching on/off handcart 9, shift fork 6, first connecting rod 3, second connecting rod 2 and turn shoulder bar 1, described first connecting rod 3 one end is rotationally connected on the carrier 4, the other end is hinged with one end of second connecting rod 2, the other end of described second connecting rod 2 is hinged with shift fork 6, and described shift fork 6 bottom and the one end turning shoulder bar 1 are connected；Described first connecting rod 3 and described in turn shoulder bar 1 opposite direction rotating.The structure of four link type, stability is high, it is not easy to malfunctioning.
Described shift fork 6 is Y shape shift fork 6.One end of the Y shape opening part of described shift fork 6 and one end of second connecting rod 2 are hinged, the bottom of described shift fork 6Y shape and turn one end of shoulder bar 1 and be fixed as overall, turn shoulder bar 1 and link with shift fork 6 described in namely.In the state of test position, when namely taking out switching on/off handcart 9, described in turn one end that shoulder bar 1 is not connected with described shift fork 6 beyond described bearing 4 edge.
Described bearing 4 is provided with chute 7, and switching on/off handcart 9 promotes the shift fork 6 can first connecting rod 3, second connecting rod 2 and turn shoulder bar 1 and rotate to working position from test position in chute 7.
Described bearing 4 is arranged over spacing roller bearing 8 at chute 7, moves spacing for switching on/off handcart 9, can prevent switching on/off handcart 9 from offsetting up under reaction force acts upwards.Multiple described spacing roller bearings 8 are mounted equidistant.Further increase stability and operable degree that switching on/off handcart 9 promotes.
