Embodiment
A support insulator failure detector as shown in Figure 1 and Figure 2, comprises bearing structure, hoisting gear, rotational structure three funtion parts.In order to improve overall intensity, all structures are all that titanium alloy is made, and make the utility model overall weight be only 9KG like this, and a liter weight can reach 150KG, and good rigidly, indeformable.Wherein bearing structure is the framework that underframe crosspiece 2 and underframe are indulged shelves 1 and surrounded.Two foundation frame crosspieces 2 and two foundation framves are indulged shelves 1 and just can be surrounded framework under normal circumstances.But for needing the situation detecting heavier support insulator, also can additionally arrange underframe crosspiece 2, extra underframe crosspiece 2 quantity arranged is not limit, but can not have influence on rotational structure.Described hoisting gear is arranged on two underframe crosspieces 2, comprise through underframe crosspiece 2 and and the screw mandrel 7 that is threaded of underframe crosspiece 2, be fixed on bottom described screw mandrel 7 on support bar 8, described screw mandrel 7 top is provided with rotation hand wheel 5.By such structure, when whole device is placed on underground, rotate rotation hand wheel 5, because support bar 8 supports on the ground, can not rotate, the underframe crosspiece 2 be therefore threaded with screw mandrel 7 just by screw mandrel 7 to having lifted.If operated by two people, need the rotation hand wheel 5 of both sides to rotate, if the words of one man operation need the rotation hand wheel 5 of taking turns flow rotation both sides simultaneously.Wall scroll shape support bar 8 can make device carry out work in hogwallow, complicated landform, is more suitable for working-yard.Also can install rubber protection pad additional in support bar 8 bottom in some occasions, reduce the wearing and tearing of support bar 8
Described rotational structure comprises rotational structure and guide frame.
As shown in Figure 3, described rotational structure comprises a movable block 15 be erected on bearing structure, through a rotation axis 3 in the middle of described movable block 15, described rotation axis 3 front end is fixed with a swivel arm 4, swivel arm 4 is fixed with a fixed block 16 away from rotation axis 3 position, fixed block 16 just in time mates mutually with the mounting hole on support insulator enamel, guarantees that fixed orifice can be stuck on mounting hole, so just can guarantee can not deviate from when rotating.A pressing handwheel 17 is provided with above described rotation axis 3, described guide frame comprises angle sheave holder 11, described angle sheave holder 11 connects at least two transfer arms be parallel to each other 12 by fixing handwheel 10, and described transfer arm 12 front end is provided with angle sheave 13.The friction force of angle sheave 13 is strong, flexible rotation.Described hoisting gear also comprises location guide 6, and described location guide 6 length is not shorter than screw mandrel 7 length, and its one end is fixed on support bar 8, and be arranged in parallel with screw mandrel 7.Location guide 6 quantity is two and divides to be located at screw mandrel 7 left and right sides.The movable block 15 of described rotational structure is fixed on bearing structure by the rotary screw 9 at two ends, and the angle sheave holder 11 in guide frame is directly fixed on two foundation framves indulges between shelves 1.Described angle sheave 13 for axle, is surrounded by one deck rubber gasket outside described angle sheave 13 with transfer arm 12.Described underframe is indulged in the middle part of shelves 1 and is provided with bent axle 19, is provided with fine grinding hand and lifts rod 18 in the middle part of described bent axle 19.Only need holding fine grinding hand during carrying the utility model, to lift rod 18 liftable, indulges in the middle part of shelves 1, therefore exert a force as laborsaving here because bent axle 19 is in underframe.Described underframe crosspiece 2 and underframe are indulged shelves 1 upper end and are flushed, and the thickness of underframe crosspiece 2 adds the thickness of support bar 8 just in time for the thickness of shelves 1 indulged by underframe.With a handles 14 on described rotation hand wheel 5.
Comprise the following steps during the use of the utility model support insulator failure detector:
Step 1: rotate rotation hand wheel 5 and make bearing structure be in extreme lower position; Rotational structure is set to the position farthest away from guide frame, spacing between two transfer arms 12 is set to maximum;
Step 2: lift support insulator failure detector, confines a support insulator by bearing structure;
Step 3: the movable block 15 of adjustment rotational structure and swivel arm 4, be inserted into the flange of support insulator by the fixed block 16 of rotational structure; Adjustment transfer arm 12 position, makes the angle sheave 13 of two transfer arms 12 just in time block the other end of support insulator;
Step 4: the rotation hand wheel 5 rotating both sides, lifts whole bearing structure, thus by unsettled for the support insulator be fixed on rotational structure;
Step 5: by rotary motion arm 4, makes support insulator carry out the circumferential movement that can't harm; Thus support insulator is adjusted to arbitrary angle and detect a flaw;
Step 6: fall support insulator after flaw detection, gets back to original position, withdrawing device, completes flaw detection work.
Wherein when one man operation, described step 5 is by fixing by pressing handwheel 17 position rotating back prop insulator after rotary motion arm 4.
Compared to the prior art, prior art, when carrying out flaw detection preliminary work, needs the support insulator that tiles, and makes spacing between two at more than 100mm, and add wooden unit feet bottom every support insulator, in order to avoid support insulator rolls.This process is according to previous experiences, and the tiling completing 10 support insulators needs 2 people to spend 16min.In flaw detection process, need take out wooden unit, rotate in a circumferential direction to coordinate crank detection test to support insulator, its process is: get wooden unit, lift, rotate, set level, cushioning wooden unit, and the consumption of 1 support insulator is 2 people 1.4min.Spent on 10 support insulators cooperation man-hour is 2 people 30min.
Adopt after the utility model, pure cooperation man-hour that the distance not needing to guarantee between support insulator only needs 1 people to carry out 1 support insulator is 1 people 1min, and pure cooperation man-hour of 10 support insulators is 1 people 10min.Time is original 1/3, coordinates personnel amount can reduce to 1 people from 2 original people.
According to statistics, for the newly-built transformer station of 218kV, post insulator quantum count is 449 disconnector support insulators containing bus grounding switch, lightning arrester, loose mail arrival, according to previous experiences, the flaw detection cooperating completing this electric substation needed for 2 people 15 days=30 work days, according to calculating, needed for 1 people 5 days=5 work day after adopting this device, if labour cost is by 180 yuan/day, then 1 newly-built 218kV transformer station can save labour cost 25*180=5000 unit.
If the power transformation branch office production task of a year is arranged by 4 newly-built 218kV transformer stations, so within 1 year, can reduce expenses 18000 yuan.And the utility model applied range, the use of the various model support insulator of 35kV, 110kV, 218kV can be met completely, and durable in use.At the trial, flaw detection professional know from experience: the utility model left-hand seat is very fast, for flaw detection work provides good condition, makes determining defects more comfortable.
