Abstract
The invention discloses a kind of portable disconnecting switch fingertip changes instrument, including lower fingertip fixing device and upper fingertip fixing device, described lower fingertip fixing device includes base plate, baffle plate, transverse slat and lower push-rod；Upper fingertip fixing device includes fingertip fixed frame, connecting plate and is connected to the upper push-rod in the middle part of fingertip fixed frame；The upper end of the end of described connecting plate and baffle plate is hinged.When dismounting disconnecting switch fingertip, lower fingertip is put in the opening between base plate and transverse slat, base plate and transverse slat are positioned to lower fingertip and are fixed, upper fingertip is put in fingertip fixed frame, enforce upper push-rod and lower push-rod again, the pulling force that fingertip spring can be overcome breaks fingertip and lower fingertip into two with one's hands, so as to easily upper fingertip and lower fingertip being loaded onto or dismantling disconnecting switch, so that integrally pulling down without by disconnecting switch during maintenance fingertip, maintenance is more convenient, labor intensity is lower, work efficiency is higher.
Description
Technical field
The present invention relates to a kind of instrument, particularly to a kind of replacing instrument taking formula disconnecting switch fingertip.
Background technology
The Main Function of transformer station is that 110kV and 35kV high-tension electricity is converted to 10kV low tension, more defeated through distribution line
Deliver to huge numbers of families.Therefore, the reliability service of substation equipment, has vital work for vast customer electricity quality
With.Disconnecting switch is the important component part of transformer station, and its Main Function is insulating power supply and the change method of operation carries out back brake
Operation, ensures operating personnel's personal safety.
As " the obvious cut-off point " of converting equipment, disconnecting switch fingertip runs in various extreme climate environments can be constantly
Aging, easily the defects such as heating, loose contact occur, easily break down it is often necessary to carry out interruption maintenance.In prior art,
Maintenance to disconnecting switch fingertip needs to pull down whole disconnecting switch, disconnecting switch is transferred to other places and is keeped in repair,
Therefore in maintenance process, the fingertip of not only disconnecting switch to be dismounted, also wants integral disassembly, assembly disconnecting switch, working strength is larger, dimension
Repair that time-consuming, increased the power off time of grid equipment, have a strong impact on power supply reliability.
Content of the invention
In view of this, it is an object of the invention to provide a kind of portable disconnecting switch fingertip changes instrument, existing to solve
Maintenance high labor intensive, the maintenance problem that time-consuming of formula disconnecting switch fingertip is taken in technology.
The present invention portable disconnecting switch fingertip changes instrument, including lower fingertip fixing device and upper fingertip fixing device,
Described lower fingertip fixing device include base plate, the baffle plate being vertically fixed on base plate two ends, be fixed on two baffle plate upper ends transverse slat, with
And the lower push-rod being fixedly connected with base plate；
Described upper fingertip fixing device includes rectangle fingertip fixed frame, is connected to the company at fingertip fixed frame two ends
Plate and be connected to the upper push-rod in the middle part of fingertip fixed frame；
The upper end of the end of described connecting plate and baffle plate is hinged.
Further, the two ends of described fingertip fixed frame are articulated and connected with connecting plate.
Further, described connecting plate is provided with bar shaped adjustment hole, the jointed shaft of described connecting plate and baffle plate is located in adjustment hole.
Further, the back segment of described upper push-rod is hinged with L-shaped pull bar.
Beneficial effects of the present invention：
The present invention portable disconnecting switch fingertip changes instrument, when dismounting disconnecting switch fingertip, lower fingertip is put into bottom
In opening between plate and transverse slat, base plate and transverse slat are positioned to lower fingertip and are fixed, and upper fingertip is put into fingertip fixed frame
In, then enforce upper push-rod and lower push-rod, the pulling force of fingertip spring can be overcome to break fingertip and lower fingertip into two with one's hands, so as to light
Upper fingertip and lower fingertip are loaded onto or are dismantled disconnecting switch so that without will be overall for disconnecting switch during maintenance fingertip by loose ground
Pull down, maintenance is more convenient, labor intensity is lower, work efficiency is higher.
Brief description
Fig. 1 is the perspective view that the present invention portable disconnecting switch fingertip changes instrument.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As illustrated, the present embodiment portable disconnecting switch fingertip changes instrument, include lower fingertip fixing device and upper tactile
Refer to fixing device, described lower fingertip fixing device includes base plate 1, the baffle plate 2 being vertically fixed on base plate two ends, is fixed on two baffle plates
The transverse slat 3 of upper end and the lower push-rod 4 being fixedly connected with base plate；
Described upper fingertip fixing device includes rectangle fingertip fixed frame 5, is connected to the company at fingertip fixed frame two ends
Plate 6 and be connected to the upper push-rod 7 in the middle part of fingertip fixed frame；
The upper end of the end of described connecting plate 6 and baffle plate 2 is hinged.
The present embodiment portable disconnecting switch fingertip changes instrument, when dismounting disconnecting switch fingertip, lower fingertip is put into
In opening 8 between base plate and transverse slat, base plate and transverse slat are positioned to lower fingertip and are fixed, and upper fingertip is put into fingertip and fixes
In frame, then enforce upper push-rod and lower push-rod, the pulling force of fingertip spring can be overcome to break fingertip and lower fingertip into two with one's hands, so as to
Easily upper fingertip and lower fingertip are loaded onto or dismantle disconnecting switch so that maintenance fingertip during without disconnecting switch is whole
Body is pulled down, and maintenance is more convenient, labor intensity is lower, work efficiency is higher.
As the improvement to the present embodiment, the two ends of described fingertip fixed frame 5 and connecting plate 6 are articulated and connected, and this improvement makes to touch
Refer to fixed frame 5 can rotate, easier can put into fingertip in fingertip fixed frame, be conducive to improving work efficiency.
As the improvement to the present embodiment, described connecting plate is provided with bar shaped adjustment hole 9, described connecting plate and baffle plate hinged
Axle 10 is located in adjustment hole, and this improvement enables jointed shaft 10 to move along adjustment hole, makes the range of activity of fingertip fixed frame 5 more
Greatly, the fingertip that can preferably adapt to different model disconnecting switch is changed.
As the improvement to the present embodiment, the back segment of described upper push-rod 7 is hinged with L-shaped pull bar 11, changes fingertip mistake
Lower push-rod 4, after breaking upper fingertip and lower fingertip into two with one's hands, is caught on, at this moment operator no longer enforces by Cheng Zhong with L-shaped pull bar 11
Upper and lower push rod also can keep the aperture between fingertip and lower fingertip constant, so as to more easily carry out the dismounting of fingertip, fingertip
Dismounting is more laborsaving.
Finally illustrate, above example only in order to technical scheme to be described and unrestricted, although with reference to relatively
Good embodiment has been described in detail to the present invention, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent, the objective without deviating from technical solution of the present invention and scope, and it all should be covered at this
In the middle of the right of invention.
