Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of charged for replacement insulator novel split-pin device, be applicable to the charged socket-clevis eye opening direction insulator spring catch vertical of winning, be implemented in and adopt the earth potential mode to change operation under the charged situation with line direction.
The utility model technical solution problem adopts following technical scheme:
The novel split-pin device of charged for replacement insulator comprises:
One nipper pliers, the first pincers handle middle and lower part of described nipper pliers vertically is fixedly connected with a cross bar, and described cross bar extends towards the second pincers handle place of described nipper pliers and the end of cross bar offers pin-and-hole;
One can be fixedly connected on the screw mandrel on insulating bar top, vertically is fixedly connected with curved crank on the described screw mandrel, offers the arc-shaped slot that passes for the described second pincers handle on the described crank.
Design feature of the present utility model also is: the pin-and-hole on the described cross bar be in the described first pincers handle and second clamp the handle pin joint under, offer groove on the crank of described arc, the A termination of described groove is bordering on the junction of described crank and described screw mandrel, and the B end of groove extends to the end of described crank; Described nipper pliers has two kinds of operating states, and under the jaw closed, described screw mandrel passes the pin-and-hole of described cross bar, and the described second pincers handle passes described groove and is in the A end place of groove; Jaw opens under the maximum rating, and described screw mandrel passes the pin-and-hole of described cross bar, and the described second pincers handle is in the B end place of groove.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Insulator spring catch split-pin device of the present utility model, the first pincers handle of nipper pliers is connected on the screw mandrel by cross bar, wire rod thread is connected in the top of insulating bar, on screw mandrel, vertically be fixedly connected with the crank of an arc, the second pincers handle of nipper pliers passes the groove of crank, when rotary screw rod, crank rotates and its groove impels the second pincers handle to open, can realize the folding of nipper pliers jaw, with clamping and take off the spring catch of insulator, because the jaw and the insulating bar of nipper pliers are in a straight line, and are applicable to the charged socket-clevis eye opening direction insulator spring catch vertical with line direction of winning, guarantee power network safety operation and power supply continued reliability.
Description of drawings:
Fig. 1 is the structural representation of the utility model split-pin device; Fig. 2 is that the A of Fig. 1 is to cutaway view.
Number in the figure: 1 first pincers handle, 2 cross bars, 3 second pincers handles, 4 screw mandrels, 5 cranks, 6 grooves.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Fig. 1,2, the split-pin device of present embodiment is applicable to the charged socket-clevis eye opening direction insulator spring catch vertical with line direction of winning, to change insulator.This split-pin device comprises:
A nipper pliers (or flat-nose pliers, the pincers handle is slim-lined construction), the first pincers handle, 1 middle and lower part at nipper pliers vertically is fixedly connected with a cross bar 2, cross bar is towards a side of the second pincers handle 3 of nipper pliers, and the end of cross bar offers pin-and-hole and passes for screw mandrel 4, but the lower end screw thread of screw mandrel 4 is fixed in the top of insulating bar, vertically is fixedly connected with curved crank 5 on described screw mandrel 4, offers the arc-shaped slot 6 that passes for the second pincers handle 3 on the described crank 5.
In specifically being provided with, pin-and-hole on the cross bar 2 be in the first pincers handle 1 and second clamp handle 3 pin joints under, promptly be in the centre of the first pincers handle and the second pincers handle, the arc-shaped slot of offering on the crank 5 has A, B two ends, the A termination is bordering on the junction of crank 5 and screw mandrel 4, and the B end of groove extends to the end of crank 5.Work Tipping Center mouth tonger has two states, and under the jaw closed, screw mandrel 4 passes the pin-and-hole of cross bar and is rotary with nut with slip-off preventing, but screw mandrel can rotate in pin-and-hole, and the second pincers handle 3 of nipper pliers passes groove 6 and is in the A end place of groove.Rotate insulating bar and drive screw mandrel 4 and rotate, crank 5 rotates simultaneously, impel second pincers handle 3 along the groove slide relative to B end place, this moment, jaw opened to maximum rating, insulating bar circles round behind the spring catch of jaw clamping insulator, impel the second pincers handle 3 along the groove slide relative to A end place, jaw is promptly closed to be clamped spring catch and it can be taken off.The jaw of the utility model insulating bar and nipper pliers opens and closes direction and can remain on the horizontal line, is applicable to the work of winning spring catch when changing the insulator operation vertical with line direction of socket-clevis eye opening direction.Solve alive circuit insulator earth potential and changed operation, prevent to swing to lack of standardization because of socket-clevis eye, or give inconvenience that the upkeep operation personnel bring because the W pin can't adopt the earth potential mode to change operation after resetting, equal potential working, interruption maintenance certainly will will be taked, reduce the equal potential working risk, strengthened the planned of maintenance.
