Put cat ladder 5.
In order to adapt to the transformer high-voltage bushing of different model, which is also equipped with
Multiple retainer plates 24 for selecting.Retainer plate 24 is annular in shape, so as to the outer ring edge with outer ring and inner ring, outer ring have with
The second location hole 25 that first positioning hole 12 on operation body panel 4 matches, so as to retainer plate 24 by with first positioning hole
12 and second the second bolt that matches of location hole 25 and be connected with operation body panel 4.24 internal diameter of retainer plate is used to match height
The spacer flanger of pressing sleeve pipe, then different retainer plates 24 are with different internal diameters, so as to the intermediate method from different bushings
Orchid matches.The inner ring edge of retainer plate 24 has several and the corresponding third location hole of screw hole on spacer flanger
26, so as to bushing by the third bolt that matches with the screw hole on in-between flange and third location hole 26 and with fixation
Circle 24 is connected.The spacer flanger of general high voltage casing can at least be connected there are four screw hole with third location hole 26.
Above-mentioned transformer high-voltage bushing upkeep operation frame can be by the wheel 2 that each 1 bottom of supporting leg is installed and easily
It is mobile.When needing mobile, the adjustable support foot 3 on 2 side of wheel, which need to be rotated to its supporting block 9, leaves working face（Ground）,
So as to operation frame can individually or drive transformer high-voltage bushing move.After reaching appointed place, adjustable support foot 3 is screwed off
Carrying bolt 8 and make supporting block 9 and working face（Ground）Rigid contact, firmness total and that entire operation frame can be increased,
It places operation frame to alter shifting or topple over, protects the bushing on operation frame and the work people for being overhauled, being tested on operation frame
Member.
When middle part, the lower part to bushing are overhauled and during test connection, fixed ladder 13 can be utilized without making
With ramp 16.And when the top to bushing is needed to be overhauled and during test connection, ramp 16 is risen with manpower, is made
In the locating slot 23 for obtaining 17 embedded operation body panel of second support bar, 4 side, and pass through the first crosspiece 19, the second crosspiece 20 and connect
Connecting bolt and fix ramp 16, be allowed to be fixedly connected with 4 phase of operation body panel, and without gap is shaken, at this time i.e. using solid
Fixed ladder 13 and ramp 16.After ramp 16, which rises, to be fixed, enough safe distances are kept with the insulator of bushing, until
Ramp 16 will not encounter insulator during rising, and avoid damage insulator.Staff is upward from fixed ladder 13 and ramp 16,
Its security insurance band can be fixed on the second cross bar 18 of ramp 16（After mobile and arrival job position）, made with increasing
The safety of industry（State Grid Corporation of China electric power safety working regulation 15.1.8 provides that the hook or rope of safety belt should hang over knot
On real firm component or aim on the steel wire rope of hanging safety belt.Forbid hanging on mobile or unstable object）.It is above-mentioned to climb
The design of ladder 5, strengthens the security reliability of staff and improves service work efficiency, avoid portion on high voltage bushings
During maintenance, the inconvenience and security risk that are worked using overlength double ladder are limited using the place of trolley or installation scaffold
It is cumbersome with it is inefficient.In cat ladder 5, connection bolt may be used M12 galvanized bolts, shearing resistance at least in more than 37000N,
It is fully able to bear the weight of staff and tool materials（The weight is no more than 100kg）.
Operation body panel 4 is matched with partial high pressure casing spacer flanger, and casing can be directly lifted on operation body panel 4,
Four 16mm first positioning holes 12 screw hole corresponding with bushing spacer flanger of operation body panel 4 is bolted.In addition
Design can be selected sequentially with major vendor, the matched several retainer plates 24 of model bushing shell for transformer spacer flanger.
To fix, rod piece made of a face right angle iron bar can be dismantled in operation body panel 4 three face（Dismantle two, both sides 12mm
It is bolted）, such bushing can be lifted on operation body panel 4 from side, it is in place after removal and installation again right angle iron bar
Rod piece（Partial high pressure casing does not need to retainer plate 24 can be directly in place；Need the casing of retainer plate 24 can be before in place, solid
Surely circle 24 is mounted on the spacer flanger lower part of bushing, is connected with, then in place）.4 three face of operation body panel is fixed,
Dismountable design on one side had not only improved bushing slinging work efficiency, but also increased the safety during bushing lifting
（Conventional high-tension sleeve hoisting method is bushing vertical rise and fall, this operating experience and casing to driving or hoistman
Vertically bind it is more demanding, casing sling after slightly tilt rise and fall difficulty and safety is just significantly greatly increased）.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement according to this, can not the scope of protection of the utility model be limited with this.
It is all according to the spirit of the present invention substantially equivalent change or modification for being made, should all cover the scope of protection of the utility model it
It is interior.
