Description
Technical field
The present invention relates to a kind of switch, is especially a kind of earthed switch.
Background technology
In the traction distribution system of electric locomotive, earthed switch is typically fitted with, when will be to the traction distribution of locomotive
Overbottom pressure when system is keeped in repair, in will first making earthed switch close a floodgate to discharge traction distribution system, it is ensured that maintenance personal
Safety.The earthed switch being generally used in the traction distribution system of electric locomotive generally comprises base plate and is connected on base plate
Left plate and right plate, support plate and main shaft are provided between left plate and right plate, multiple static contacts are connected with support plate
Component, is connected with the moving contact for being engaged with multiple static contact components on main shaft, main shaft two ends reach left plate and the right side
The outside of side plate, is connected with swing arm on main shaft left end, extension spring, left side are provided between the upper end of swing arm and the lower end of left plate
Plate is provided with the first limited block and the second limited block for limiting swing arm hunting range, and main shaft right-hand member is connected with handle, by pulling
Fixed handle can control the folding between moving contact and static contact.Although the earthed switch of said structure has obtained widely should
With, but there is three below weak point in this earthed switch：1st, the pulling force of larger extension spring is overcome due to pulling handle, because
This, starting to pull when handle makes moving contact close a floodgate with static contact component larger power will be used, and make one to feel to pull handle conjunction
Lock is very laborious；2nd, because earthed switch is typically mounted in distribution box, the side of handle is only exposed towards outside, therefore, it is difficult to
It is to be in open a sluice gate state or "on" position to observe earthed switch from the outside；3rd, it is any because earthed switch does not have fixed structure
People can pull handle, therefore, often there is maloperation.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind when handle combined floodgate is pulled, and makes one to feel very laborsaving, and
Switching state can conveniently be observed, be prevented from the earthed switch of others' maloperation.
The technical solution of the present invention is to provide a kind of earthed switch, including base plate, handle and is connected on base plate
Left plate and right plate, support plate and main shaft are provided between left plate and right plate, multiple static contacts are connected with support plate
Component, is connected with the moving contact for being engaged with multiple static contact components on main shaft, main shaft two ends reach left plate and the right side
The outside of side plate, is connected with swing arm on main shaft left end, extension spring, left side are provided between the upper end of swing arm and the lower end of left plate
Plate is provided with the first limited block and the second limited block for limiting swing arm hunting range, wherein, also including panel, panel is by more
Individual pole is connected with right plate, and the centre of panel is provided with rotary shaft, and the two ends of rotary shaft are located at respectively the left and right sides of panel,
Handle is connected to the right-hand member of rotary shaft, and the left end of rotary shaft is connected with control panel, and control panel is provided with arc-shaped through-hole, arc-shaped through-hole
Inside it is placed with and stirs spring, the left and right two ends of control panel is connected to the left end cap and right end cap covered on arc-shaped through-hole, it is left
End cap is provided with deep-slotted chip breaker, and the right-hand member of main shaft is connected with shifting block, and the right-hand member of shifting block is connected with plate, and plate is provided with plate, inserts
Plate is inserted in arc-shaped through-hole through deep-slotted chip breaker, and the one end for stirring spring is withstood on plate, and the other end for stirring spring withstands on control
On disk, the periphery of control panel is provided with the first positive stop lug boss and the second positive stop lug boss for limiting control panel slewing area, panel
Left side is provided with spacer pin, and spacer pin is inserted between the first positive stop lug boss and the second positive stop lug boss, and indicator board is connected with shifting block, is referred to
Show that the periphery of plate is provided with the first instruction boss and second and indicates boss, panel is provided with peep hole, when moving contact and stationary contact
In when opening a sluice gate position, first indicates that boss is corresponding with peep hole to head assembly, when moving contact and static contact component are in combined floodgate
During position, second indicates that boss is corresponding with peep hole, and panel is provided with opens a sluice gate status lock and "on" position lock, opens a sluice gate status lock
It is provided with and opens a sluice gate lock core pole, "on" position is locked and is provided with combined floodgate lock core pole, the section for opening a sluice gate lock core pole and combined floodgate lock core pole is in
Semicircle, the periphery of control panel is provided with first and opens a sluice gate locked groove and the first combined floodgate locked groove, and the periphery of indicator board is provided with
Two open a sluice gate locked groove and the second combined floodgate locked groove, when moving contact and static contact component in open a sluice gate position when, first opens a sluice gate locked groove and the
Two open a sluice gate locked groove screws in for opening a sluice gate lock core pole, when moving contact and static contact component are in closing position, the first combined floodgate locked groove
It is used for the lock core pole screw-in that closes a floodgate with the second combined floodgate locked groove.
After using above structure, compared with prior art, earthed switch of the present invention has advantages below：1st, when pulling this
Bright handle is rotated when closing a floodgate, and what is driven first is that control panel is rotated, and at this moment stirring spring can be gradually compressed, and slowly increase bullet
Power, when the elastic force for stirring spring increases to certain numerical value, stirring spring can promote plate to rotate, and plate is rotated can pass through shifting block
Main shaft is driven to overcome the pulling force of extension spring to rotate, so that moving contact closes a floodgate with static contact component, by the above course of work,
With prior art when closing a floodgate, pulling handle will overcome the pulling force difference of larger extension spring, and what the present invention overcame first is to stir
