For driving interface, the staircase structural model of 41 center section of driving gear shaft can be by driving component 40 in the first fagging 21 or second
Axially position is carried out on fagging 22.
Please continue to refer to Fig. 4, active adjustment gear 42 respectively with the first driven 32 and second driven adjusting tooth of adjustment gear
The intermeshing of wheel 52, and active adjustment gear 42, the number of teeth phase of the first driven 32 and second driven adjustment gear 52 of adjustment gear
Deng, the thread rotary orientation on screw thread and second end of thread 511 on first end of thread 311 on the contrary, in the present embodiment, the first screw thread
Screw thread on end 311 is right-hand thread, and the screw thread on second end of thread 511 is left-hand thread.
When frock is replaced in assembling, first, the second driven subassembly 50 is set to pass through 22 screw thread of second end of thread 511 and the second fagging
Coordinating, driving component 40 is completed by driving gear shaft 41 and its staircase structural model and the cooperation and positioning of the second fagging 22, the
One driven subassembly 30 passes through 21 thread fitting of first end of thread 311 and the first fagging.Then, by the first fagging 21 and the second fagging
22 is opposite, the second driven subassembly 50 is contacted positioning with 21 face of the first fagging by the second positioning ring 53, driving component 40
Corresponding aperture coordinates positioning on the other end and the first fagging 21, and the first positioning end 312 of the first driven subassembly 30 passes through the second fagging
22.Finally, the first positioning ring 33 of the first driven subassembly 30 is screwed on the first positioning end 312 of the first driven subassembly 30,
Until the first positioning ring 33 and 22 finished surface face of the second fagging are engaged, the assembling of frock is replaced in so far completion.
Next it is described as follows with reference to the course of work of replacement frocks of the Figure 11 to the embodiment of the present invention.
As shown in figure 11, by taking IGCT is pressed string device replacement as an example, the 3rd IGCT61 damage from top to bottom.First, unload
Fall the pressure assembling force on IGCT press fittings string 60, the front end of the first fagging 21 and the second fagging 22 of replacing frock is inserted into damage
In the notch of the radiator 62,63 of the adjacent upper and lower ends of IGCT61, then, spanner (not shown) and driving gear shaft 41 are used
On outer-hexagonal driving interface coordinate driving driving component 40 to rotate, and then promote the first driven subassembly 30 and the second driven subassembly
50 rotate together, and in the replacement frock location shown in Figure 11, the second fagging 22 is motionless, and the first fagging 21 will be to moving up
It is dynamic, so as to drive the device of radiator 62 and its top to move up 3mm or so.Then, maintenance personnel is by the IGCT61 of damage
Pull out and from location structure, and change normal IGCT, rotated backward using spanner driving driving component 40, make the first support
Plate 21 moves down, and radiator 62 and its device of top move down in drive, after upper radiator 62 is contacted with IGCT
Frock is replaced in extraction.Finally, press fitting load is applied to IGCT press fittings string 60.
It can be seen from the above that whole device replacement process can be quickly and easily accomplished under the operation of a maintenance personnel.Due to
It is electrically connected between radiator by soft busbar, and radiator is positioned with IGCT by location structure, so that in changer
It can ensure to replace during part when frock driving element moves up and keep stablizing, and in the opposite diode of IGCT press fitting strings
Press fitting string is not required to dismantle connection bolt of the soft busbar on press fitting string when moving freely 3 to 5mm upwards, substantially reduces workload.
It is appreciated that above-mentioned replacement process is equally applicable to diode press fitting string 70, details are not described herein.
To sum up, the press fitting string device of the embodiment of the present invention is replaced frock and is at least had the advantages that：
(1) agent structure for replacing frock is gear assembly and fagging, has succinct quick machine between fagging and press fitting string
Tool interface, makes full use of the design feature of press fitting string and radiator, and operating efficiency is high；
(2) both sides of driving component respectively set a driven subassembly, and three components are arranged into linear type, advantageously reduced
Fagging front end formation loaded torque pressure caused by the thread fitting, ensure user's operation and replace the work of frock
Safety, and replaced available for the device in long press fitting string；
Between (3) first driven subassemblies and the first fagging and the thread fitting between the second driven subassembly and the second fagging
Position is symmetrical, and so as to put use according to actual conditions both forward and reverse directions, operation is flexible；
Matched somebody with somebody between (4) first driven subassemblies and the first fagging and between the second driven subassembly and the second fagging using screw thread
Close, deadlock property based on thread fitting and can continuous moving characteristic so that fagging spacing can be stably held in maintenance personnel
It is easy to operation within the scope of needing；
(5) it is simple and compact for structure, device replacement can be rapidly completed under one man operation, is suitable for offshore wind farm and ship etc.
The small occasion of site space, while influence caused by production smaller.
