Description
Technical field
The present invention relates to a kind of switching-on/off device for pressure plates.
Background technology
The protection pressing plate is the more and frequent element that needs operation of transformer station's usage quantity; the operation that it usually need to drop into or withdraw from along with the state of main equipment; the input of so-called protection pressing plate refers to after in flakes its top and the bottom being communicated with, the operation of again top nut and lower nut being tightened.So-called withdrawing from of pressing plate of protection refers to first its top nut and lower nut be unclamped the operation that will open in flakes again.Traditional mode of operation is directly to tighten or unclamp lower nut on it with hand, has following shortcoming: to need to drop into or withdraw from protection pressing plate quantity many because of each operation, so waste time and energy; The strength that the operator uses is different, the motionless phenomenon of pine when normal appearance protection pressing plate need withdraw from; The protection pressing plate is when dropping into, and two nuts all will be tightened up and down, easily leak nutting and cause loose contact.
Summary of the invention
The object of the invention is to provide a kind of easy to operate switching-on/off device for pressure plates.
To achieve these goals, the present invention adopts following technical scheme: switching-on/off device for pressure plates, comprise housing, the upper and lower gear that is provided with travelling gear in the housing and is meshed with travelling gear respectively, the axle outer end of travelling gear is provided with turning handle, axle the inner of upper and lower gear is respectively equipped with upper and lower sleeve, distance between the upper and lower nut of the distance between the upper and lower sleeve and pressing plate equates, upper and lower sleeve is provided with the little wedged hole of outer imperial palace, and a perisporium is provided with the raised tooth of extending along the hole depth direction in the hole.
Described upper and lower sleeve rear end arranges quill shaft, quill shaft is partly docked by the coaxial outer section part of cover and the coaxial inner segment of cover and is formed, the outer end of overlapping coaxial outer section part is connected with the up/down sleeve, dock with the outer end of the coaxial inner segment part of cover the inner of overlapping coaxial outer section part, the outer section of quill shaft section diameter is greater than quill shaft inner segment section diameter, and the inner of the outer section part of quill shaft and the distance values between the housing are less than the numerical value of the precession degree of depth of the upper and lower nut of pressing plate; Square gear shaft inner hole is set in the gear shaft of upper and lower gear, and the quill shaft inner segment partly is provided with the square cylinder structure and is located in the gear shaft inner hole; The inner of quill shaft inner segment part is provided with regulating nut, and the cap body diameter of regulating nut is greater than the diameter of gear shaft inner hole; Between upper and lower sleeve and the upper and lower gear spring is set.
Be provided with support at the housing that is provided with upper and lower sleeve one side.
Described housing comprises front and rear panels, and fixed support is set between the front and rear panels, travelling gear is set between the front and rear panels, cogs and lower gear.
The present invention has following advantage: easy to carry when the protection switching-on/off device for pressure plates uses, flexible operation is reliable, saves the operating time of dropping into or withdrawing from the protection pressing plate; Use the protection switching-on/off device for pressure plates to drop into the protection pressing plate, compress strength basically identical, do not exist different operators because of the different phenomenons that are difficult to become flexible of strength; After using the protection switching-on/off device for pressure plates to drop into the protection pressing plate, it contacts up and down well, and the electric loop performance is unaffected; When using the protection switching-on/off device for pressure plates, support and the protection screen plane contact, stablize nonvoluntary swing during operation.
The outer section of quill shaft section diameter partly forms stop greater than the sleeve inner segment; can guarantee the upper and lower nut that when withdrawing from the protection pressing plate, do not come loose; when dropping into the protection pressing plate, be unlikely stubborn too tight, make different users aeration level and compression strength when operation manage consistent.Between upper and lower sleeve and the upper lower gear spring is set, when operation, can moves forward and backward along with the rotation of the upper and lower nut of protection pressing plate.Upper and lower sleeve is provided with the little wedged hole of outer imperial palace, is easy to block the upper lower nut of protection pressing plate during use.
