Description
Technical field
The application relates to a kind of wind turbine rotor locking framework.
Background technique
Wind turbine in the work is subjected to great wearing and tearing, therefore must not timing it is safeguarded and/or repairs.In these maintenance processes, need stop the rotation of wind turbine rotor and with locked rotor to the fixed position, so that wheel chain can not mesh when guaranteeing that the workman works.
EP 1291521A discloses a kind of existing mechanism of locked rotor as mentioned above that is used for.Here, the rotor disk locking device is installed to the air guide sleeve supporting mechanism, and rotor disk is installed to wheel hub thus.For locked rotor, the movable axis of rotor disk locking device can join in the cone shape hole of rotor disk.Therefore, when movable axis engaged, rotor was by wheel hub maintenance relatively.Particularly, as described in Figure 2, rotor locking device preferably includes cone shape hole 43, and air guide sleeve is provided with movable axis 41, and movable axis has tapered end, cooperating with the cone shape hole 43 of rotor disk, thereby has locked rotor disk.Diminished shaft and hole allow the misalignment between compensating shaft and the hole, and eliminate or reduce gap between axle and the hole.Preferably, air guide sleeve has and is positioned at the shifter that air guide sleeve is used for shifting axle.Arrange that in air guide sleeve this device makes workman's the locking and unlocking rotor safely.Shifter comprises manually operated runner 42 in this example, and it also can be used for regaining the axle of release rotor.Can not rotate in case rotor is locked, rotor disk just is fixed to the front portion of air guide sleeve by rotor disk fixing device 12.The rotor disk fixing device comprises a plurality of (for example 12) bolts (referring to Fig. 4 of EP 1291521A) that are positioned at the air guide sleeve front portion.Rotor can be by being fixed to the air guide sleeve front portion with these bolton to rotor locking device 5b.Behind these bolts, stud bolt and nut can be mounted to be fastenedly connected fastening.In case rotor disk is locked and suitably fixing, replaceable gear-box, main shaft and main bearing, and do not need to remove blade and/or wheel hub.
Yet prior art constructions is firm inadequately, can not be at the aerodynamic force of for example need be under strong wind sky situation handling the chain that is delivered to wind turbine during locked rotor.
The model utility content
The utility model relates generally to a kind of rotor locking device that locked rotor is prevented its rotation.
More specifically, the utility model relates to a kind of locked rotor system, and wherein main shaft is by with respect to the locking of main bearing housing, and this locking device is integrated on the main bearing housing.
The utility model provides a kind of locked rotor mechanism, be used for locked rotor in main bearing, bearing is positioned on the air guide sleeve bedframe, described locking framework comprises: the locking wheel disc, it is connected to the adpting flange of rotor at first end of rotor, locking device, it is integrated on the described main casing and comprises the locking cylinder that axially stretches out to the locking wheel disc from the main body of locking device, wherein said locking wheel disc comprises the hole that is used to receive the locking cylinder, and the locking cylinder is movable does and move vertically so that engage or throw off hole in the locking wheel disc.
Description of drawings
Fig. 1 is the schematic representation of wind turbine rotor locking framework of the present utility model.
Fig. 2 is the schematic representation of the wind turbine rotor locking framework of prior art.
Embodiment
In Fig. 1, main shaft 1 is arranged in main bearing 2, and main bearing 2 location also are fixed on the bedframe 3 of air guide sleeve.First end of main shaft 1 is connected to the wheel hub of wind turbine 4 by the adpting flange 5 of main shaft 1, and second section of main shaft 1 is connected to the gear-box (not shown).
According to the utility model, locking framework comprises locking wheel disc 6, and it is connected to adpting flange 5 by for example bolt 12.In addition, locking framework comprises the locking device 7 that is integrated in the main bearing 2.
Locking device 7 is included in the locking cylinder 8. locking wheel discs 6 that squeeze out from locking device 7 and comprises that preparation is used to receive the hole of locking cylinder 8 on the axial direction of locking wheel disc 6.Locking cylinder 8 can move and move along its axis so that engages or throw off the hole that locks in the wheel disc 6.Locking cylinder 8 comprises major diameter lock section 9 and minor diameter lock section 10.
Preferably, the action and its position of locking cylinder are manually controlled by screw rod 11, and described screw rod engages the main body of lock section 9 and locking device 7.
Advantage of the present utility model is locking device 7 very near the bedframe 3 of air guide sleeve and closely connection with it, so rotor can substantially directly be fixed on the very firm bedframe of structure 3.
Another advantage of the present utility model is to avoid with locked rotor for example to lock onto on the air guide sleeve substructure of part as the hypotaxis of pod body on more unsubstantial structure.
But also a kind of very firm structure can be provided, because the main bearing housing itself is exactly very solid structure.Therefore, can guarantee that locking framework of the present utility model can be in the face of the power from rotor.
As an alternative, the axial position of locking cylinder 8 can electronicly be controlled.
As an alternative, but the locking cylinder 8 the axial position pneumatic control.
As an alternative, but the locking cylinder 8 the axial position hydraulic control.
As another embodiment of the present utility model, the main bearing housing comprises two or more locking devices 7.This has guaranteed to be shared by the cylinder of each locking device from the power that acts on the cylinder of rotor, and can further alleviate the weight of each locking device.
