Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of point machine include locking ferrum 1, actuating strut group 2,
Driving group 3, detection group 4 (left detection group 41, right detection group 42), automatic lid actuator 5 are (left
Automatic lid actuator 51, right automatic lid actuator 52), indication rod group 6, casing 7；Actuating strut group
2 at least a termination expose casing 7, be used for connecting point tongue or movable point frogs；Action
Bar group 2 includes actuating strut 21, lock dog frame 22, lock dog 23, actuating sleeve 24；Lock dog frame 22
Centre has fluting, fluting direction to be connection locking ferrum 1 and the direction of actuating strut 21；Indication rod
Group 6 and actuating strut 21 are arranged in parallel through casing 7, and indication rod group 6 exposes termination and action
Bar 21 exposes termination and is positioned at casing 7 homonymy；Indication rod group 6 is provided with breach, respectively correspondence
Left detection group 41 in detection group 4 and right detection group 42, when breach moves to corresponding left detection
During group 41 or right detection group 42, left detection group 41 or right detection group 42 just can enter expression
The gap position of bar group 6, the part of the most left detection group 41 or right detection group 42 is by table
Show that bar group 6 is blocked, it is impossible to motion puts in place；The left automatic lid actuator of corresponding automatic lid actuator 5
This is made display by the combining form that 51 or right automatic lid actuator 52 contact groups switch on and off.
Driving group 3 is arranged in above or below actuating strut group 2, and both length directions are parallel,
For the output motion of drive actions bar group 2 and power.
Installing lock dog 23 in the medial launder of lock dog frame 22, lock dog frame 22 and lock dog 23 pass through pin
Axle connects, and lock dog 23 can rotate in lock dog frame 22 groove around bearing pin, when lock dog 23 moves
During to locking ferrum 1 termination, lock dog 23 rotates, and coordinates with locking ferrum 1 end circular arc, makes
Make bar 21 can not reversely displacement, point machine realizes locking.
Actuating sleeve 24 clamping or be socketed on actuating strut 21, lock dog frame 22 is " U " type structure,
Lock dog frame 22 is connected formation neutral with actuating strut 21, and actuating sleeve 24 is positioned at lock dog frame 22 with dynamic
Make, in the neutral that bar 21 is formed, to slide in this neutral shift range；When actuating sleeve 24 moves,
Lock dog 23 can be made to promote lock dog frame 22 by bearing pin, so pushing action bar assembly 2 moves or
Lock dog 23 is made to be rotated into locking/unlocked position.The reciprocating part of driving group 3 snaps in driving
Set 24 or be fastenedly connected with actuating sleeve 24 or traverse of leaving a blank is connected.Driving group 3 drives actuating sleeve
24 move back and forth.
Actuating strut group 2 is provided with lock dog 23, and the side of lock dog 23 is close to locking ferrum 1.
Locking ferrum 1 and actuating strut group 2 are arranged in parallel.Locking ferrum 1 point can squeeze type and can not squeeze type.
Type locking ferrum 1 can be squeezed be fixed in casing 7 by flexible member, when squeezing of being subject to of locking ferrum 1 is de-
When power is more than setting value, there is enough elastic deformations in flexible member, and locking ferrum 1 is squeezing de-power
Being subjected to displacement under effect, the locking of point machine lost efficacy.Type locking ferrum 1 can be squeezed fix simultaneously
Structure is provided with shift detector, detects the misalignment of locking ferrum 1 in real time, work as locking
When the displacement of ferrum 1 exceedes setting value, the contact that shift detector is connected disconnects.Type can not be squeezed
Locking ferrum 1 is directly fixed in casing 7, is not provided with shift detector in its fixed structure.
Left detection group 41 is arranged in actuating strut group 2 and stretches out the position of end of a period, right detection group 42 cloth
Put and draw in, in actuating strut group 2, the position that motion ends；Left detection group 41 and right detection group 42 energy
Overall along being perpendicular to the direction slip that actuating strut 21 moves；The most left detection group 41,
Right detection group 42 contacts with actuating strut 21 or actuating sleeve 24；Left detection group 41 and a left side are opened automatically
Closing device 51 to coordinate, right detection group 42 and right automatic lid actuator 52 coordinate, according to actuating sleeve 24
Position make automatic lid actuator 5 connect different contact groups with the position of indication rod group 6, and then
The contact group being also turned on by left automatic lid actuator 51 and right automatic lid actuator 52 and disconnect
Various combination represents the different conditions residing for goat.
Direction in below describing is all on the basis of being facing perpendicularly to view.
In Fig. 1, lock dog 23 coordinates with locking ferrum 1 termination, and actuating sleeve 24 stops lock dog 23
Rotate counterclockwise.So lock dog 23 can not move upward, and then actuating strut group 2 can not be to
Upper motion, is blocked in this position.The most left detection group 41 is promoted compression bullet by actuating sleeve 24
Spring, entirety moves right and puts in place, and the rotating shaft of corresponding left automatic lid actuator 51 loses support,
Under the effect of its spring, offside contact has been connected in contact conversion.
In Fig. 3, actuating strut 21 has moved to intermediateness.From the beginning of Fig. 1 state, drive
Set 24 is driven up motion by driving group 3, and first actuating sleeve 24 loses and rotates lock dog 23
Restriction, and then promote lock dog 23 rotate unlock.Stop owing to lock dog 23 is blocked ferrum 1,
Turned position is limited, and actuating sleeve 24 just promotes lock dog 23 to move upward, and then pushing action bar
21 move upward.During actuating sleeve 24 moves upward, left detection group 41 promotes at spring
Lower to left movement, and then promote the axis of rotation of left automatic lid actuator 51, disconnection has turned on
Contact, until connect opposite side contact.This state, left detection group 41 and right detection group
42 all contact with actuating strut 21.
In Fig. 4, actuating strut 21 moves to another ultimate position and enters locking states.From Fig. 3
State starts, and driving group 3 promotes actuating sleeve 24 to continue up, until lock dog 23 moves
To the another one termination of locking ferrum 1, no longer being supported by locking ferrum 1, lock dog 23 is driving
Rotating counterclockwise under set 24 promotion, after turning over certain angle, actuating sleeve 24 continues up
Lock dog 23 is made not rotate clockwise.Actuating strut 21 is locked in another ultimate position.Drive
Dynamic set 24 promotes right detection group 42 compression spring during moving upward, and entirety moves right.
The rotating shaft of corresponding right automatic lid actuator 52 loses support, and under the effect of its spring, contact turns
Change, disconnect original contact and connected offside contact.
