It is provided with in the position that the body of rod 1 outer wall is corresponding with pulling force gear 12 and can move axially along the body of rod 1 and pulling force can be blocked
Gear 12 makes what it cannot rotate fixture block 25.Pulling force gear is coaxially connected with swinging handle.
Wherein:
1, the body of rod is made up of the little bar of more piece, the most totally 10 joint, and wherein a joint saves, according to reality headed by being periproct, a joint
Border situation determines body of rod length.Every a length of 1m of pole, hollow, in addition to head saves, other every poles are the ending identical straight-bars of diameter.
The top of first pole is relatively thin, and end is identical with other pole diameters.Rely on threaded between each joint；
2, first joint tail diameter is 4cm, and top diameter is 2.5cm, has screw thread, is used for placing one hands of spring tongs
Handle, place suitable with spring tongs length is provided with auxiliary wire-hanging hook；
3, the anti-skidding insulation sleeve of periproct and spool；
4, spring tongs is for changing the action direction of check bar, and can alleviate first joint end needs stress simultaneously, side
Just check bar operation is the biggest but also is engaged tight object.One handle of this pliers tail end has screw thread, is used for being screwed in first pole end, another
Handle has annular aperture, and being used for is draught line, and jaw is circular arc width mouth；
5, spool spool is used for being wound around draught line, and its rotating distance is opened for the tail end controlling spring tongs
Close, it is possible to pliers folding degree is carried out electrodeless regulation and reliably fixes；
6, stable support reduces strength suffered by check bar end, simultaneously works as supporting spring tongs and is at stable
And balanced action；
7, auxiliary stay hook is used for being wound around line, take-up, alleviates p-wire gravity suffered by check bar end with this and causes
Pulling force；
8, suture introducing needle is for when connecting each joint check bar, in advance by the draught line of tail end one by one through each pole bar
Body.
Utility model works process:
1, according to on-the-spot distance, such as 4.5m, choose the little bar of more piece and can connect into corresponding length, such as 5m length,
That includes first joint, each joint and three joints of centre of periproct；
2, first with suture introducing needle, draught line is fixed at spring tongs handle after each pole body, is then passing through screw thread
Joint test bar, and connect spring tongs；
3, object will be connect to be placed in spring jaw, and be placed stable firm；
4, line is being assisted on wire-hanging hook around loose circle；
5, lift check bar, when being connect after object puts in place, rotate spool, discharge the handle of spring tongs lentamente, directly
Decontrol completely to by folder object；
6, being displaced outwardly junction pole, the coiling on auxiliary wire-hanging hook is automatically releasable；
7, check bar is put down.
Process of taking out stitches is contrary with said process.
And in the process, as in figure 2 it is shown, when draught line 5 pulls downwards, the opening of spring tongs 2 gradually bite by
Folder thing, and now, along with draught line 5 moves down, lifter rack 11 engages downwards pulling force driving gear 12 and pulling force driving cog
Wheel 13 rotation, rotates counterclockwise exactly according to shown in Fig. 2, and then pulling force travelling gear 13 drives upper driving cog by chain 14
Wheel 15 and upper pinion rotate, and upper pinion drives upper transfer gear and driving gear 17 to rotate by upper driving chain 16,
Drive gear 17 to engage advance and retreat tooth bar 18 (left side in figure) backward mobile, and then drive two card chelas 19 to help to contract
Help spring tongs 2 to be clamped by gripped object, promote fixture block 25 to make it block pulling force driving gear 12 then up and prevent it from rotating,
And when needs release gripped object, slide downward fixture block 25, away from pulling force driving gear 12, then decontrols draught line 5,
Make lifter rack 11 upwards engage pulling force driving gear 12 and pulling force travelling gear 13 rotates, and then made by chain reaction
Tooth bar 18 of must retreating moves forward (right side in figure is moved), and then two card chelas 19 are flared out, unclamp by
While clamping thing, the front end of advance and retreat tooth bar 18 also can head on gripped object and move forward, and then completes actively to unload held
The process of thing, two card chelas 19 of whole process are further ensured that the clamping degree of gripped object, meanwhile, utilize fixture block to prevent from drawing
Moving gear 12 of advocating rotates and also further increases safety, because because draught line 5 needs to receive one during operation
The pulling force of individual tension, therefore, excessive once long-time use or gripped object, easily there is the danger broken in draught line 5,
And once break and will easily cause gripped object and drop, the most easily hurt operating personnel, and during dropping
Also other equipment of easily damage construction cause any property loss, and the equipment dropped itself once to break also be a loss, and
Have employed fixture block 25 by after fixing for pulling force driving gear 12, even if the unexpected fracture of draught line 5, two card chelas 19 also can still be protected
Hold clamped condition, do not have above-mentioned potential safety hazard, considerably increase the safety of construction, and on the other hand pressed from both sides when unloading
When holding thing, advance and retreat tooth bar 18 has the active thrust promoting forward gripped object, so narrow and small at some or circuit is more
Space in will significantly facilitate unloading gripped object, and without this mechanism, then in some slightly larger spaces or
It not that very complex environment has only to trip spring pliers 2 then slight jitter spring tongs 2 and utilizes spring tongs 2 to be moved
Move to suitable position, but when the space of narrow and small or complex circuit, do not shake spring tongs 2 space or
Person shakes spring tongs 2 can exist potential safety hazard, the most thus cannot deliver to gripped object accurately specify position, and adopt
With just solving this problem after the active offloading functions of advance and retreat tooth bar 18.
Using effect
The program is tested in Shenyang electrical test class of O&M branch, and comparing result is as follows:
A, primitive operation method
1, seat belt is checked, if having breakage or aging conditions；
2, fasten the safety belt, seat belt is tied up on the body of climbing person；
3, hanging safety belt, is enclosed within seat belt on sleeve pipe to be climbed；
4, bushing is climbed, operating specification posture during climbing；Highest point employee's health is positioned at horizontal plane 8m eminence；
5, singlehanded thick clamp, buttresses seat belt and grasps sleeve pipe on the other hand, and both legs climb tight sleeve pipe；
6, setting of casing, pine seat belt, according to normalizing posture setting of casing.
During wiring, although librarian use seat belt, but its health remains unchanged high-altitude how high for unsettled 8m, exist
Dangerous.Further, owing to process of the test needs personnel to climb the most up and down, so test period is longer, one need of a wiring
Want time half a day, not only have influence on when time test efficiency, have shadow also for total power failure duration and the operation to unit below
Ring.
B, use check bar
1, determine required check bar joint number according to practical situation, splice check bar；
2, check bar end will be put in by folder testing wire clamp；
3, check bar is lifted as corresponding site；
4, check bar is regained after pine bar
Using check bar wiring, it is possible to avoid personnel to climb, operating process is simple, without dangerous, it is possible to when shortening test
Between, improve test efficiency.
This utility model in view of the situation that causes injury to personnel, life to be on the hazard due to climbing sleeve pipe occurred,
By contrasting above-mentioned wiring process, employ check bar of the present utility model and 500kV transformator is carried out test wire connection, not only
Simple to operate, it is also possible to shorten test period, improve test efficiency, simultaneously it can be avoided that personnel's climbing is positioned at the appearance set in high-altitude
Pipe, protects testing crew personal safety.It alleviates 500kV transformer/reactor test difficulty, can complete connecing of test requirements document
Line, improves the efficiency of experiment.
