Abstract
A kind of closing keeping device of primary cut-out hydraulic disk spring operating mechanism, it includes top board, latch, gripper shoe, upper reset spring, lower back-moving spring, push rod, regulation bolt, alignment pin, locating stop piece, it is characterized in that: top board and push rod are connected by latch, upper reset spring is positioned on push rod by alignment pin and locating stop piece, and gripper shoe matches with top board and push rod.The advantage that this utility model has closing keeping device simple in construction, parts machining difficulty is low, with low cost and safe and reliable.
Description
Technical field
This utility model relates to high-voltage switch gear technical field, a kind of primary cut-out hydraulic disk spring operating mechanism
Closing keeping device.
Background technology
Primary cut-out is the key component of electric power network, the reliability of its performance, to ensureing that power supply has decisive work
With.Operating mechanism as the driving means of chopper, directly drives the breaking-closing operating of chopper, its importance do not say and
Analogy.So, it is ensured that operating mechanism is reliable, stable operation is the most important thing in the work of electric power network system Construction.And chopper
During combined floodgate, if abnormal decompression occurs in hydraulic mechanism, may result in chopper and depart from closing position, this situation will be to electricity
Force system constitutes serious threat, not permitted when being Operation of Electric Systems.Existing operating mechanism closing keeping device, bag
Including hydraulic pressure to close a floodgate and machinery combined floodgate two ways, hydraulic pressure closes a floodgate and there is the processing request of part and cost is higher, structure ratio
More complicated, and the shortcoming that security reliability is inadequate.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, safe and reliable, when hydraulic mechanism decompression, still ensures that
Chopper is maintained at the closing keeping device of the primary cut-out hydraulic disk spring operating mechanism of "on" position.
This utility model be achieved in that it include top board, latch, gripper shoe, upper reset spring, lower back-moving spring,
Push rod, regulation bolt, alignment pin and locating stop piece, is characterized in that: top board and push rod are connected by latch, and upper reset spring passes through
Alignment pin and locating stop piece are positioned on push rod, and gripper shoe matches with top board and push rod.
It is low, with low cost that this utility model has closing keeping device simple in construction, parts machining difficulty, and safety
Advantage reliably.
Accompanying drawing explanation
Below in conjunction with accompanying drawing this utility model done under description:
The structural representation of the closing keeping device of Fig. 1 primary cut-out hydraulic disk spring operating mechanism.
Detailed description of the invention
As it is shown in figure 1, the closing keeping device of this primary cut-out hydraulic disk spring operating mechanism include top board 1, latch 3,
Gripper shoe 4, upper reset spring 5, lower back-moving spring 6, push rod 7, regulation bolt 8, alignment pin 9, locating stop piece 10, locating stop piece 11
Being connected by latch 3 with locating stop piece 12, top board 1 and push rod 7, upper reset spring 5 is fixed by alignment pin 13 and locating stop piece 12
Position is on push rod 7, and gripper shoe 4 matches with top board 1 and push rod 7.Latch 3 is inserted on top board 1 and push rod 7.Push rod 7 sets
It is equipped with and controls the upper reset spring 5 that push rod 7 moves down, the lower back-moving spring 6 that controlroof 1 resets.Top board pivot point is arranged on
On support.Push rod 7 is porose, and upper spring 5 is positioned by locating stop piece 10 and locating stop piece 11, and locating stop piece 10 upper end is by location
Pin 9 is fixed, and locating stop piece 11 lower end and top board upper-end contact, push rod 7 is through about 4 two holes of gripper shoe, and gripper shoe 4 is to top board
1 plays a supportive role, and gripper shoe 4 is fixed on the support of hydraulic mechanism, and the upper end of lower spring 6 contacts with the lower surface of gripper shoe 4,
Lower end is positioned by locating stop piece 12 and alignment pin 13, and top board 1 is fixed on the support of mechanism by pin joint, push rod 7 lower end
Having female thread, regulation bolt 8 to be connected with push rod 7 by this female thread, adjusting nut 8 can be according to practical situation regulation push rod
Length, adjusting nut 8 lower end contacts with the fixed cover of mechanism's disc spring upper end, and latch 3 plays the effect of a switch, and latch 3 is inserted
To top board 1 with the hole in push rod 7, then this utility model acts the effect kept of closing a floodgate, and extracts latch 3, then this device does not acts as
With；When mechanism's energy storage, after mechanism closes a floodgate, if there is decompression, push rod 7 is also upper to be moved, and push rod 7 withstands connecing of mechanism
Head, even if decompression state, push rod 7 Ye Nengshi mechanism is in combined floodgate hold mode.
