Embodiment 1
Refering to Fig. 1, Fig. 2 and Fig. 3, in the present embodiment, a kind of locking device is proposed, including locking pin 100 and driving group
Part 200.Drive component 200 drives locking pin 100 to move so that and locking pin 100 is inserted into corresponding rotatable parts 300, so as to
Realize the locking to rotatable parts 300.
When plant maintenance is overhauled, locking device causes the state of 300 remains stationary of rotatable parts, with safeguard work personnel
Safety.
As shown in Figure 1, locking pin 100 includes main body 110 and plunger 120, main body 110 is fixedly connected with plunger 120.Its
In, main body 110 and plunger 120 can be with integral structures.
Plunger 120 is corresponding with rotatable parts 300.When locking device carries out locking work, plunger 120 is inserted into rotatable parts
In 300, lock rotatable parts 300.
As shown in figure 3, the lock hole 310 of truncated cone-shaped can be designed on rotatable parts 300, the plunger 120 of locking pin 100 with
Lock hole 310 corresponds to.
In the present embodiment, plunger 120 is in prismatic table shape.
Wherein, the area of the upper surface of plunger 120 is less than the area of lower face.The lower face of plunger 120 and main body 110
Head is fixedly connected.
Under the driving of drive component 200, plunger 120 is gradually inserted since end face thereon to corresponding locking pin 100
In rotatable parts 300.Since plunger 120 is in prismatic table shape, with going deep into for plunger 120, plunger 120 finally with rotatable parts 300
Clamping, completes the locking to rotatable parts 300.
Again since plunger 120 uses prismatic table shape structure, plunger 120 is when locking rotatable parts 300, the seamed edge of plunger 120
It is in contact with the lock hole 310 of rotatable parts 300, the contact area between plunger 120 and lock hole 310 is small, can generally regard
For point contact.Contact area between plunger 120 and lock hole 310 is smaller, and in separation, frictional force between the two etc. is mutual
Active force also can be smaller, so that the two is more easily separated.
As shown in Fig. 2, drive component 200 includes fixed seat 210 and connector 220.
Connector 220 includes mounting head 221 and fixed link 222, is fixedly connected between mounting head 221 and fixed link 222.Together
When, fixed link 222 is fixed in fixed seat 210.
In the present embodiment, the tail portion of main body 110 is provided with blind hole 111, mounting head 221 be inserted into blind hole 111 and with it is blind
Hole 111 is slidably and sealingly connected with.
Wherein, the cross section of blind hole 111 is circle, and mounting head 221 and fixed link 222 are cylinder.Mounting head 221 with
The axial line of fixed link 222 is conllinear.Meanwhile the cross-sectional area of mounting head 221 is more than the cross-sectional area of fixed link 222.
As shown in figure 3, the schematic diagram for locking device.Wherein, locking device is by locking pin 100 and drive component 200
It is formed after installation connection.Wherein, fixed seat 210 is fixed in equipment, for example, when being locked to the rotor disk of wind-driven generator
When, fixed seat 210 is just fixed in the rack 400 of wind-driven generator.
As shown in figure 4, first annular seal space 230 is formed between mounting head 221 and blind hole 111.To realize to locking pin 100
Driving, is provided with the first pipeline 231 being connected with first annular seal space 230 on connector 220.Mounting head 221 and blind hole 111
Between be slidably and sealingly connected with, when fluid is injected into first annular seal space 230, the pressure in first annular seal space 230 can increase.Gu because
Reservation 210 is fixed in equipment, while the fixed link 222 of connector 220 is fixed in fixed seat 210, so locking pin 100 exists
It is moved to the left under the action of 230 internal pressure of first annular seal space relative to connector 220.During locking pin 100 is moved to the left,
Plunger 120 can be gradually inserted in lock hole 310, then complete the locking work to rotatable parts 300.
After the completion of Maintenance and Repair work, need that locking pin 100 is made to detach with rotatable parts 300.
With reference to Fig. 5, for this purpose, in the present embodiment, the opening of blind hole 111 is provided with and 111 fixed seal connection of blind hole
Sealing cover 130, fixed link 222 passes through and sealing cover 130 and is slidably and sealingly connected with sealing cover 130.Mounting head 221, fixed link
222nd, the second annular seal space 240 is formed between blind hole 111 and sealing cover 130.Wherein, it is provided on connector 220 and the second sealing
The second pipeline 241 that chamber 240 is connected.
When being detached to locking pin 100 with rotatable parts 300, first annular seal space 230 is sucked out by the first pipeline 231
Interior fluid, and pass through the second pipeline 241 and inject fluid into the second annular seal space 240.Since first annular seal space 230 and second is close
Seal the effect of pressure in chamber 240 so that locking pin 100 moves right, and realizes the separation of locking pin 100 and rotatable parts 300.
To ensure the leakproofness of 230 and second annular seal space 240 of first annular seal space, between mounting head 221 and blind hole 111,
Sealing element is may be provided between fixed link 222 and sealing cover 130.Wherein, sealing element can use sealing ring etc..
As shown in Fig. 3, Fig. 4 and Fig. 5, for ensure locking work reliability, prevent locking pin 100 in locking process with
Rotatable parts 300 detach, and in the present embodiment, the tail portion of main body 110 is provided with locating rod 140, is set in fixed seat 210 useful
In the anti-back bar 250 for withstanding locating rod 140.
Wherein, locating rod 140 and main body 110 can use be threadedly coupled.In this way convenient for the dismounting of locating rod 140 and more
It changes.
Installation through-hole can be provided in fixed seat 210, guide sleeve 260 is provided in installation through-hole.Wherein, anti-back bar
250 are located in guide sleeve 260.The locating rod 140 on locking pin 100 is withstood using anti-back bar 250, locking pin 100 is made to fix not
It is dynamic.
For ease of the installation of anti-back bar 250 and its adjusting of position, internal thread is provided on the inner wall of guide sleeve 260, it is right
The external screw thread to match with internal thread is provided on the anti-back bar 250 answered.Due to screw thread between anti-back bar 250 and guide sleeve 260
Connection, it is possible to the length in 250 screw-in guide sleeve 260 of anti-back bar be adjusted according to the position of locking pin 100, so that anti-back bar
The fixed effect of 250 pairs of locking pins 100 reaches best.
As shown in fig. 6, the both ends of anti-back bar 250 are respectively arranged with the first bar portion 251 and the second bar portion 252.
First bar portion 251 and the second bar portion 252 are both provided with external screw thread, meanwhile, the length of the first bar portion 251 is less than second
The length of bar portion 252.Wherein, the length of the first bar portion 251 and the second bar portion 252 should be configured as needed, specific as follows：
As shown in Figure 4 and Figure 6, when locking pin 100 performs locking work, the second bar portion 252 of anti-back bar 250 is screwed in
In guide sleeve 260, at this point, anti-back bar 250 can contact with locating rod 140 and withstand locating rod 140, locking pin 100 is made to fix not
It is dynamic.
As shown in Figure 5 and Figure 6, it when locking pin 100 is not carried out locking work, then does not need to limit locating rod 140
System, at this point it is possible to which the first bar portion 251 of anti-back bar 250 is screwed in guide sleeve 260, anti-back bar 250 does not connect with locating rod 140
It touches, the activity space of locking pin 100 is not limited by anti-back bar 250.
In the present embodiment, the displacement sensor for detecting 100 location information of locking pin is provided on locking device.Profit
