Main shaft lock construction.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of lock spindle of wind power generating set
Structure, including positioning disk, tapered sleeve, mechanical pins and installation bolt, which is characterized in that it is inserted with tapered sleeve in the positioning disk,
The tapered sleeve is fixed in positioning disk by multiple installation bolts；One end of the mechanical pins is inserted in the center of tapered sleeve, described
The first counterbore is offered on the end face of positioning disk, the bottom center of first counterbore offers pin hole, the end of the positioning disk
Multiple threaded holes being along the circumferential direction angularly distributed centered on pin hole are also provided on face.
Preferably, one end of the tapered sleeve is inserted in pin hole, and the other end of the tapered sleeve has been outwardly formed flange collar, described
Flange collar is inserted in the first counterbore.
Preferably, multiple the second counterbores being along the circumferential direction angularly distributed are offered in the end face outside of the flange collar,
The quantity of second counterbore is equal with the quantity of the first counterbore.
Preferably, the bottom center of each second counterbore offers a through-hole, each through-hole and each
Threaded hole is arranged concentrically.
Preferably, inserted with an installation bolt in each second counterbore, the end of thread of the installation bolt is worn
It crosses through-hole and is screwed into threaded hole, so that the tapered sleeve is fixed in positioning disk.
Preferably, the center of the tapered sleeve offers taper hole, and one end of the mechanical pins is formed with conehead, the conehead
The taper of taper and taper hole cooperates.
Compared with the prior art, the advantages of the utility model are: the utility model, which has, makes heart function by oneself, that is, work as machinery
When the axis of pin and the center line of tapered sleeve have large error, spindle lock function also can be easily realized, it is easy to operate and high-efficient；
Because the hardness number of mechanical pins is greater than the hardness number of tapered sleeve, it is ensured that when wear-out failure occurs for the two, failure must be tapered sleeve, and
Tapered sleeve is small-scale structure part, is bolted in the pin hole for being fixed on positioning disk by installation, so being easily changed, is substantially reduced more
Change this into, labor intensity is small.
Detailed description of the invention
Fig. 1 is the sectional structure chart of the utility model.
Specific embodiment
As shown in Figure 1, a kind of main shaft lock construction of wind power generating set, including positioning disk 1, tapered sleeve 2, mechanical pins 3 and peace
Fill bolt 4；Tapered sleeve 2 is inserted in positioning disk 1, tapered sleeve 2 is fixed in positioning disk 1 by multiple installation bolts 4；Mechanical pins
3 one end is inserted in the center of tapered sleeve 2, and the other end of mechanical pins 3 is fixed on pedestal 5 and has the function of horizontal extension；Positioning
Offer the first counterbore 11 on the end face of disk 1, the bottom center of the first counterbore 11 offers pin hole 12, on the end face of positioning disk 1
It is also provided with multiple threaded holes 13 being along the circumferential direction angularly distributed centered on pin hole 12；One end of tapered sleeve 2 is inserted in pin
In hole 12, the other end of tapered sleeve 2 has been outwardly formed flange collar 21, and flange collar 21 is inserted in the first counterbore 11, the outboard end of flange collar 21
Multiple the second counterbores 23 being along the circumferential direction angularly distributed, the quantity of the second counterbore 23 and the first counterbore 11 are offered on face
Quantity is equal, and the bottom center of each second counterbore 23 offers a through-hole 24, each through-hole 24 and each threaded hole 13
It is arranged concentrically；Inserted with an installation bolt 4 in each second counterbore 23, the end of thread for installing bolt 4 passes through through-hole 24
And be screwed into threaded hole 13, so that tapered sleeve 2 is fixed in positioning disk 1；The center of tapered sleeve 2 offers taper hole 22, mechanical pins 3
One end be formed with conehead 31, the taper of conehead 31 and the taper of taper hole 22 cooperate；The hardness number of conehead 31 is greater than taper hole
22 hardness number.
In use, the positioning disk 1 of the utility model to be arranged in the side of pedestal 5, and make the internal diameter of taper hole 22 larger
One end towards pedestal 5；Then rotational positioning disk 1 will so that the center line of tapered sleeve 2 and the center line of mechanical pins 3 substantially overlap
Mechanical pins 3 are stretched out, until conehead 31 is inserted into taper hole 22, because of the self-centering spy between the conical surface on conehead 31 and taper hole 22
Property, the center line of the center line and mechanical pins 3 that realize tapered sleeve 2 automatically is completely coincident, and then prevents positioning disk 1 from continuing to rotate,
To realize the locking of positioning disk 1；When needing to unlock, mechanical pins 3 are retracted into original position.
The lock spindle (or wind wheel lock) of wind power generating set mostly uses mechanical pins directly to contact with positioning disk pin hole greatly at present
Form, pin hole diameter be slightly larger than mechanical pins diameter, mechanical pins are inserted into positioning disk pin hole, realize the function of spindle lock
Energy；Because of the uncertainty in wind load direction, when lock spindle needs to act, positioning disk be not it is fixed, have
The phenomenon that swinging, this allows for mechanical pins and is not easy to be rapidly inserted into the pin hole of positioning disk, and troublesome in poeration and efficiency is lower,
In addition, will certainly occur to wear and fail under the action of wind load, both for big because of mechanical pins and positioning disk Long Term Contact
Part is not easy to replace, and replacement cost is high, large labor intensity；The utility model, which has, makes heart function, the i.e. axis when mechanical pins 3 by oneself
When the center line of line and tapered sleeve 2 has large error, spindle lock function also can be easily realized, it is easy to operate and high-efficient；Because of machine
The hardness number of tool pin 3 is greater than the hardness number of tapered sleeve 2, it is ensured that and when wear-out failure occurs for the two, failure must be tapered sleeve 2, and
Tapered sleeve 2 is small-scale structure part, is fastened in the pin hole of positioning disk 1 by installing bolt 4, so being easily changed, is dropped significantly
Low replacement cost, labor intensity are small.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to
It is so possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is replaced on an equal basis
It changes；And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
