Under change technology contents, when being also considered as the enforceable category of this utility model.
As shown in Fig. 1-Fig. 7, this utility model is a kind of compressor blade locking device, and it includes locking plate 1 and at least one
Root drive shaft 2, a drive shaft 2 is provided with the tapered end 3 of at least one strip perpendicular to drive shaft 2, and described locking plate 1 is along water
Square to having the installing hole 11 equal with drive shaft 2 quantity, described locking plate 1 vertically has equal with tapered end 3 quantity
Through hole 12, described through hole 12 intersected with described installing hole 11.The position of described through hole 12 and the position of described tapered end 3
Corresponding, described drive shaft 2 is located in the installing hole 11 of locking plate 1, and described tapered end 3 is located in through hole 12.
As shown in Fig. 3 or Fig. 7, when described drive shaft 2 rotates, the two ends of tapered end 3 protrude from respectively locking plate 1 top surface and
Bottom surface, this is working condition.When blade 51 is connected with wheel disc 6, the two ends of described tapered end 3 all non-bulging in locking plate 1
Top surface and bottom surface, that is, tapered end 3 have work and inoperative two states.In order to allow tapered end 3 keep steady under two states
Calmly, under in working order, drive shaft 2 directly can be welded to ensure the position of tapered end 3 with locking plate 1, but so can reduce
Installation effectiveness, and when dismounting, damage is easily caused to locking plate 1 and drive shaft 2.Drive shaft 2 therefore described in the utility model and described
It is provided with lockable mechanism between locking plate 1, by the relative position of lockable mechanism fixed drive axle 2 and locking plate 1, permissible when being embodied as
Fixed charge method end plate on driving shaft 2, passes through end plate using pin and is finally located on locking plate 1.In the present embodiment as preferably
Scheme, as shown in figure 3, described lockable mechanism includes nut 4, the end of described drive shaft 2 is provided with the outer spiral shell with nut 4 cooperation
Stricture of vagina, described nut 4 threadeds the end in locking plate 1 for the rear top pressure with drive shaft 2, and further, described nut 4 passes through pad 41
Top pressure is in the end of locking plate 1.By the effect of frictional force, drive shaft 2 and locking plate 1 are locked.
In the present embodiment, in conjunction with Fig. 3, Fig. 5-Fig. 7, described tapered end 3 is provided with the first screw 31, and described drive shaft 2 sets
There is the second screw 21, after drive shaft 2 being penetrated the installing hole 11 of locking plate 1, using screw bolt passes the second screw 21 and first
Screw 31 is fixing with tapered end 3 by drive shaft 2.And the cooperation for the ease of drive shaft 2 and tapered end 3, in conjunction with Fig. 3 and Fig. 5, described drive
Moving axis 2 is provided with spacing hole 22, during installation, first described tapered end 3 is located in described spacing hole 22, then will be driven with bolt again
Moving axis 2 and tapered end 3 are fixing.In addition, it is also possible to directly weld tapered end 3 after drive shaft 2 being penetrated the installing hole 11 of locking plate 1
Connect on driving shaft 2.
In the present embodiment, as shown in Fig. 1 or Fig. 6, described drive shaft 2 is provided with two, and every drive shaft 2 is provided with two
Tapered end 3.
In conjunction with Fig. 1-Fig. 9, first two drive shafts 2 are respectively penetrated during installation in the installing hole 11 on locking plate 1, then adjust
The position of drive shaft 2, allows spacing hole 22 in the through hole 12 of locking plate 1, and tapered end 3 is inserted in drive shaft 2 spacing hole 22, rotates
Tapered end 3 is adjusted to horizontal level by drive shaft 2, and that is, the non-bulging top surface in locking plate 1 in tapered end two ends and bottom surface, will be locked by bolt
3 are fixedly connected with drive shaft 2.As shown in figure 9, when blade 51 is installed, first tapered end 3 is adjusted to horizontal level with blade 51
Together in the race of insertion wheel disc 6, the section of blade root 52 is substantially trapezoidal, and therefore blade 51 can be stuck in wheel disc by blade root 52
In 6, the radial position of blade 51 is limited.After blade root 52 is installed to specified location, rotates drive shaft 2, tapered end 3 is rotated 90
Degree makes it vertical with locking plate 1 upper surface, and that is, the two ends of tapered end 3 protrude the top surface with locking plate 1 and bottom surface, the tapered end end of protrusion respectively
In the race of the embedded wheel disc 6 in portion and in the mating groove of blade root 52, that is, as shown in figure 8, so embedded rear blade 51 is just by axial direction
It has been fixed on wheel disc 6, described axial direction refers to the axial direction of compressor, in fig. 8 i.e. above-below direction.Finally, by nut 4, pad
The end of piece 41 and drive shaft 2 is connected and top pressure is locked in the end of locking plate 1.For ensureing in long-play
The locking effect of situation lower nut 4, can increase a bent handle in nut 4 side, after nut 4 is tightened on driving shaft 2
After handle is bent insertion locking plate 1 on, handle can limit nut 4 and rotate, so ensure that drive shaft 2 in running not
Loosen.
In sum, this utility model compressor blade locking device, using simple, quick for installation, effectively overcomes existing
There are some practical problems in technology thus having very high value and using meaning.
Above-mentioned embodiment only illustrative principle of the present utility model and its effect are new not for limiting this practicality
Type.This utility model also has many aspects can be improving without prejudice on the premise of overall thought, for being familiar with this technology
Personage all can carry out modifications and changes to above-described embodiment without prejudice under spirit and the scope of the present utility model.Therefore,
Such as those of ordinary skill in the art is without departing from the spirit disclosed in this utility model and institute under technological thought
