Abstract
It the utility model is related to a kind of high voltage isolator fingertip changer, including pneumatic cylinder, in horizontal first push rod in the cylinder rod top of pneumatic cylinder, in horizontal second push rod in the cylinder barrel top of pneumatic cylinder, the air inlet of pneumatic cylinder connects inflator by tracheae, and installs air bleeding valve and check valve successively from pneumatic cylinder to inflator direction on tracheae.The utility model changes fingertip conveniently, greatly reducing the workload of worker, time saving and energy saving.
Description
Technical field
It the utility model is related to a kind of disconnecting switch and change instrument, more particularly to high voltage isolator fingertip changer.
Background technology
It is the routine work in power industry staff's maintenance repair to change disconnecting switch fingertip, is become in 66,220kV etc.
In power station, if overheat condition occurs in the operation of disconnecting switch fingertip or reaches the replacing time limit, it is necessary to change.Isolate changing
During switching fingertip, fingertip spring tension is bigger, at fingertip and button contact base contact site, misplace up and down because of fingertip or
Fingertip degree of rising not enough is difficult to be installed in place fingertip, changes fingertip difficulty, can not possibly architecturally complete more to change jobs substantially, often
It will often be changed on disconnecting switch integral demounting to ground, cause worker workload to increase, waste time and energy.
The content of the invention
In order to solve the above-mentioned technical problem the utility model is, there is provided a kind of high voltage isolator fingertip changer, more
Change during disconnecting switch fingertip, without disconnecting switch is dismantled into road replaced on ground, change fingertip conveniently, it can greatly be reduced
The workload of worker, it is time saving and energy saving.
Technical solution of the present utility model is：
A kind of high voltage isolator fingertip changer, including pneumatic cylinder, in horizontal first push rod in the cylinder rod top of pneumatic cylinder,
In horizontal second push rod in the cylinder barrel top of pneumatic cylinder, the air inlet of pneumatic cylinder connects inflator by tracheae, and on tracheae by
Pneumatic cylinder installs air bleeding valve and check valve successively to inflator direction.
Further preferably, guide rod is vertically arranged in the first push rod lower surface, vertical guiding is provided with the second push rod
Hole, the guide rod pass through pilot hole, make the first push rod and the second push rod face arrangement up and down, prevent from deflecting.
Further preferably, rubber cushion blocks are set in the first putter action end upper surface, in the second putter action end following table
Face sets lower rubber cushion blocks, avoids the first push rod, the second push rod and power equipment rigid contact, protects power equipment.
The upper surface at the first described putter action end sets groove, and upper rubber cushion blocks are embedded in groove, upper rubber cushion blocks
Upper surface protrude from the upper surface of the first push rod；The lower surface at the second described putter action end sets groove, lower rubber blanket
In block insertion groove, the lower surface of lower rubber cushion blocks protrudes from the lower surface of the second push rod.
The beneficial effects of the utility model are：
1st, due in horizontal first push rod in the cylinder rod top of pneumatic cylinder, in horizontal second push rod in the cylinder barrel top of pneumatic cylinder,
When changing isolation switch contact, between the first push rod and the second push rod are inserted into the upper and lower plate of fingertip, pneumatic cylinder cylinder rod is released,
First push rod and the second push rod carry out top pressure, and then the fingertip bullet that will be connected with the upper and lower plate of fingertip to the upper and lower plate of fingertip respectively
Spring is pulled open, and the fingertip of corrupted on button contact base is easily removed and installs new fingertip, and whole Renewal process need not be by disconnecting switch
Road replaced on ground is dismantled, fingertip is changed conveniently, greatly reducing the workload of worker, it is time saving and energy saving.
2nd, because the air inlet of pneumatic cylinder connects inflator by tracheae, and from pneumatic cylinder to inflator direction on tracheae
Air bleeding valve and check valve are installed successively, during inflator is passed through compressed gas to pneumatic cylinder repeatedly, check valve prevents gas
Gas backstreaming in cylinder pressure, it ensure that the cylinder rod of pneumatic cylinder is persistently stretched out；Replacement operation opens air bleeding valve after terminating can be by gas
Middle compressed gas discharge, so as to which the first push rod and the second push rod be bounced back, and takes out between the upper and lower plate of fingertip in cylinder pressure,
Make fingertip recoil of spring, clamped new fingertip by the upper and lower plate of fingertip.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- pneumatic cylinders, the push rods of 2- first, the upper rubber cushion blocks of 3-, 4- guide rods, the push rods of 5- second, rubber blanket under 6-
Block, 7- pilot holes, 8- inflators, 9- air bleeding valves, 10- check valves.
Embodiment
As shown in figure 1, a kind of high voltage isolator fingertip changer, including pneumatic cylinder 1, on the cylinder rod top of pneumatic cylinder 1
Horizontal first push rod 2, groove is set in the motion end upper surface of the first push rod 2, upper rubber cushion blocks 3 are embedded in groove, upper rubber blanket
The upper surface of block 3 protrudes from the upper surface of the first push rod, guide rod 4 is welded vertically in the lower surface of the first push rod 2, in pneumatic cylinder 1
Horizontal second push rod 5 in cylinder barrel top, groove is set in the motion end lower surface of the second push rod 5, and lower rubber cushion blocks 6 are embedded in groove
Interior, the lower surface of lower rubber cushion blocks protrudes from the lower surface of the second push rod, and upper and lower rubber cushion blocks can avoid the first push rod, second
Push rod and power equipment rigid contact, power equipment is protected, while upper and lower rubber cushion blocks are embedded in push rod by groove, it is convenient
Change；Vertical pilot hole 7 is provided with the second push rod 5, the guide rod 4 passes through pilot hole 7, pushes away the first push rod and second
Bar up and down arrange by face, prevents from deflecting；The air inlet of pneumatic cylinder 1 connects inflator 8 by tracheae, and by pneumatic cylinder on tracheae
1 installs air bleeding valve 9 and check valve 10 successively to the direction of inflator 8.
When the operation of high voltage isolator fingertip fingertip is installed, the first push rod 2 and the second push rod 5 are inserted into fingertip first
Between upper and lower plate, compressed gas then is passed through into the cylinder barrel of pneumatic cylinder 1 using inflator 8, the cylinder rod of pneumatic cylinder 1 is upward
Release, the first push rod 2 and the second push rod 5 carry out top pressure to the upper and lower plate of fingertip respectively, and then will be connected with the upper and lower plate of fingertip
Fingertip spring be opened, then the fingertip of corrupted on button contact base is removed and new fingertip is installed, finally open air bleeding valve 9, will
First push rod 2 and the second push rod 5 bounce back, and are taken out between the upper and lower plate of fingertip, make fingertip recoil of spring, by fingertip,
