Lock piece 231b is assembled, and is also convenient for that pull bar 231a or lock piece 231b are transported, changed or repaired.
The lock piece 231b of the present embodiment is threadedly coupled with the thread segment on the piston rod 12 of rotor lock rationed marketing 1.Work as piston
When thread segment on bar 12 is external screw thread, hole is threaded on lock piece 231b.When the thread segment on piston rod 12 is screwed hole
When, stud is set on lock piece 231b.Between lock piece 231b and rotor lock rationed marketing 1 by the way of being threadedly coupled, Neng Goushi
Now quick connection, lifts the versatility of provision for disengagement 2, also improves the efficiency of work of pulling pin.As shown in fig. 6, the present embodiment
Screwed hole 99 is provided with lock piece 231b, with the existing structure with the piston rod 12 of the rotor lock rationed marketing 1 shown in the present embodiment
Direct locking coordinates, it is not necessary to carries out structural modification to existing rotor lock rationed marketing 1, can realize lock piece 231b and piston rod
Quickly connected between 12.
The location-plate 232 of the present embodiment includes two or more free ends.Each free end and annular slab it
Between be provided with a hydraulic cylinder.As shown in Fig. 3, Fig. 5, when the provision for disengagement 2 of the present embodiment sets four hydraulic cylinders, this implementation
The location-plate 232 of example is cross, is positioned such that plate 232 on the premise of support transmission is met, and deadweight is relatively light, mitigates whole
The weight of individual provision for disengagement 2, facilitates carrying and installation.Criss-cross location-plate 232 includes four free ends, a free end
One end with a hydraulic cylinder is connected, and four hydraulic cylinders are distributed relative to the Central Symmetry of criss-cross location-plate 232, it is ensured that
Hydraulic cylinder applies driving force in a balanced way to location-plate 232, and then guarantee applies axial force in a balanced way to rotor lock rationed marketing 1 so that
The uniform force of rotor lock rationed marketing 1, unbalance loading, is not pulled out successfully from pin-and-hole.The free end of the location-plate 232 of the present embodiment
Quantity can according to the quantity of hydraulic cylinder come adaptability increase and decrease.Location-plate of the present utility model 232 can also be that a monoblock is justified
Shape plate or square plate.
As shown in Figure 8, Figure 9, the process that rotor lock rationed marketing 1 is extracted using the provision for disengagement 2 of the present embodiment is further described,
It is specific as follows:
The locking nut 14 of rotor lock rationed marketing 1 is disassembled first, then by the screw between blind flange 13 and stator 3
Disassemble, blind flange 13 is removed.
Then the annular slab of the provision for disengagement 2 of the present embodiment is placed on stator 3 and causes the through hole 211 on annular slab
Screwed hole with stator 3 aligns, and the screw that will be disassembled is threaded into hole again, by annular slab location and installation in stator 3
On.
Start hydraulic system 24, hydraulic cylinder extension is moved to adjust the position of location-plate 232, when lock piece 231b is moved to
During the position that can be connected with the piston rod 12 of rotor lock rationed marketing 1, stop hydraulic system 24.By lock piece 231b and piston rod
12 lockings are connected together.
Hydraulic system 24 is again started up, hydraulic cylinder stretches out motion with jacking location-plate 232.Location-plate 232 drives pull bar
231a and lock piece 231b simultaneously applies axial force by piston rod 12 to rotor lock rationed marketing 1 so that when hydraulic cylinder gradually stretches out, turn
Sub- stop pin 1 is also gradually extracted pin-and-hole.Until after rotor lock rationed marketing 1 is pulled out completely, stopping hydraulic system 24.
The provision for disengagement 2 of the utility model embodiment, is chosen portion 23 by the circumferential equally distributed drive pin of drive division 22,
Ensure the stress equalization in withdrawal process of rotor lock rationed marketing 1, it is to avoid rotor lock rationed marketing 1 rotor occurs because of unbalance stress, unbalance loading
The situation that stop pin 1 is damaged.Axial force is applied to rotor lock rationed marketing 1 by using drive division 22, it is not necessary to which extra manpower is just
Rotor lock rationed marketing 1 can be extracted, therefore use the mistake of the extraction rotor lock of provision for disengagement 2 rationed marketing 1 of the utility model embodiment
Journey is time saving and energy saving, reduces labour intensity.The provision for disengagement 2 of the utility model embodiment, can solve the corrosion of rotor lock rationed marketing 1
Under serious conditions, the problem that rotor lock rationed marketing 1 is removed cannot be manually realized, it is to avoid artificial sled dismounting mode of pulling causes generator to determine
The situation that sub 3 pin-and-hole end faces are damaged, the structure to generator plays a protective role, and saves construction cost.
The provision for disengagement 2 of the utility model embodiment can be not only used for pulling out rotor lock rationed marketing 1 as described above,
Can be used for pulling out other kinds of stop pin.When the provision for disengagement 2 of the present embodiment is used to extract other kinds of stop pin, tear open
The locking fit system that the pin of handler 2 is chosen between the lock piece 231b in portion 23 and the connecting portion of other kinds of stop pin can
Selected with the structure type of the connecting portion according to stop pin, for example can be threaded connection, claw connection, hasp connection or
The hinged mode of person realizes that locking coordinates.
Although being described to the utility model by reference to preferred embodiment, model of the present utility model is not being departed from
In the case of enclosing, various improvement can be carried out to it and part therein can be replaced with equivalent.Especially, as long as not depositing
