Further in conjunction with shown in Fig. 2-4, the jam plate 130 has a latched position and a unlocking position, when jam plate 130 is in
During latched position, it is inconsistent with lock shaft 121 so that fork 120 is locked in into first position or the second position, and jam plate 130 is in
During unlocking position, it is separated with lock shaft 121 so that fork 120 can be converted between first position, the second position；Wherein,
One elastic component 140 makes the permanent trend having to latched position rotation of jam plate 130.
Specifically, the jam plate 130 has adjacent the first lock seaming 131 and the second lock seaming 132, and fork 120 is in first
During position, the first lock seaming is 131 inconsistent with lock shaft 121, and when fork 120 is in the second position, second lockstitches a border 132 and lock shaft
121 is inconsistent, and under this two states, jam plate 130 is in latched position.It is in and releases when jam plate 130 rotates through certain angle
During lock position, lock shaft 121 can cross the first lock seaming 131, second and lockstitch a border 132 drift angles for connecting, so that fork 120 can be to
First position or the second position are rotated.
Preferably, first the 131, second lock seaming 132 of lock seaming is perpendicular, but is not limited thereto.Further, the present invention
In jam plate 130 it is in rectangular configuration, but it is not limited to rectangle, can also be arranged to other arbitrary shapes, and this is this area skill
Technology known to art personnel.
With continued reference to shown in Fig. 2, one end away from the second lock seaming 132 of jam plate 130 offers the pivoted hole in waist type
133, the 3rd connecting shaft 134 is arranged in pivoted hole 133 and is fixed in aforementioned brackets, and jam plate 130 can be around the 3rd connecting shaft
134 pivot, while arranging the pivoted hole 133 of waist type, make the limiter of speed 1 still can be with up rotation after braking.First elastic component
140 one end is fixed near one end of the second lock seaming 132, and the other end of the first elastic component 140 is fixed on by fixing axle 141
On support, and fixing axle 141 is located at the side of the second lock seaming 132, and the first elastic component 140 makes jam plate 130 permanent with to locking bit
Put the trend of rotation.In addition, the lower end of jam plate 130 is also convexly equipped with a conflict bar 135, for drive mechanism (referring to aftermentioned) phase
Coordinate, make fork 120 reset to drive jam plate 130 to rotate to unlocking position.
Further in conjunction with shown in Fig. 2-4, when limiter of speed 1 is not operating, jam plate 130 is in initial latched position, its first lock
Side 131 contradicts lock shaft 121 and fork 120 is locked in into first position, as shown in Figure 2.When limiter of speed 1 is braked, swing arm 103
Swing and promote push rod 110 to rotate clockwise, the conflict end 112 of push rod 110 promotes lock shaft 121, fork 120 is connected around second
Spindle 122 is rotated counterclockwise, i.e. moved from first position to the second position, while the second elastic component 150 is stretched；This mistake
Cheng Zhong, lock shaft 121 promotes the first lock seaming of jam plate 130 131 jam plate 130 is rotated counterclockwise around the 3rd connecting shaft 134, i.e., by
Latched position to unlocking position rotates, while the first elastic component 140 is stretched, as shown in Figure 3.When lock shaft 121 is moved to
When at the intersecting drift angle of first the 131, second lock seaming of lock seaming 132, this is a critical state (see Fig. 3) of jam plate 130, now slightly applies
Power can make lock shaft 121 cross the intersecting drift angles of first the 131, second lock seaming of lock seaming 132, make lock shaft 121 with the phase of jam plate 130
Depart from, the first elastic component 140 resets can pull jam plate 130 to recover to initial latched position, therefore the critical localisation is as locked
The unlocking position of plate 130.Jam plate 130 recovers after latched position, and its second lock seaming 132 can again contact at lock shaft 121, will put
Bar 120 be maintained at the second position and cannot return, as shown in Figure 4.The fork 120 of this position can push down the conflict on ratchet 102
Pin 104 makes it engage with ratchet 101, thus can prevent limiter of speed 1 from automatically reseting.
It is described to prevent the automatically reset device 100 of elevator speed limitor without machine room from also including on limiter of speed 1 in the present invention
Drive mechanism, it is used to driving jam plate 130 to be rotated from latched position to unlocking position, to release to the pendulum in the second position
The locking of bar 120, so that limiter of speed 1 can reset.
Further in conjunction with shown in Fig. 1-2, the drive mechanism is electric magnet 160, and electric magnet 160 is located at the bottom on limiter of speed 1
It is connected on seat 105 and with the control system located at switch board, operator are manipulated by cabinet and can make the action of electric magnet 160.
Specifically, electric magnet 160 includes a telescopic push rod 161, and the push rod 161 connects with the conflict bar 135 of the lower end of jam plate 130
Touch, when operational control cabinet make electric magnet 160 it is electric when, its release push rod 161 and promote contradict bar 135 so that jam plate 130 around
Second connecting shaft 122 to unlocking position rotates, and when conflict bar 135 rotates to the second linking arm 124 of contact, jam plate 130 rotates
To unlocking position, lock shaft 121 can cross the intersecting drift angles of first lock seaming the 131, second lock seaming 132 and go to the first lock seaming 131
Top, as shown in figure 5, now allowing the dead electricity of electric magnet 160, its push rod 161 to withdraw again, jam plate 130 is in the first elastic component 140
Latched position is pulled under effect, fork 120 then retracts first position by the second elastic component 150, and the first lock seaming 131 is contradicted again
Lock shaft 121 is so that limiter of speed 1 is resetted.
Understandably, drive mechanism is not limited to electric magnet 160.
The work for preventing the automatically reset device 100 of elevator speed limitor without machine room with reference to shown in Fig. 1-5, to the present invention
Illustrate as principle.
When 1 hypervelocity action of limiter of speed, its pendulum does centrifugal motion and pulls ratchet 102 to make its mesh ratchet gear 101, so as to
Rotate ratchet 101, ratchet 101 rotates and pulls swing arm 103 to rotate, swing arm 103 it is (as shown in Figure 1) swing and act on push rod
A points on 110 press section 113, promote push rod 110 to turn clockwise around the first connecting shaft 111, the conflict end 112 of push rod 110
Lock shaft 121 is promoted to make fork 120 around the rotate counterclockwise of the second connecting shaft 122, while the second elastic component 150 is stretched；This mistake
Cheng Zhong, lock shaft 121 promotes the first lock seaming 131 of jam plate 130 to make it around the rotate counterclockwise of the 3rd connecting shaft 134, and the first bullet
Property part 140 is stretched, as shown in Figure 3.When lock shaft 121 crosses the first lock seaming 132 intersecting drift angle of the 131, second lock seaming, its
Jam plate 130 is no longer bear against, now, the first elastic component 140 recovers deformation can retract initial latched position by jam plate 130, and make
Lock shaft 121 is withstood again in second lock seaming 132, fork 120 is locked to the second position and cannot be revert to original position, such as Fig. 4
It is shown.Now, fork 120 can contradict the conflict pin 104 on ratchet 102, make ratchet 102 by fork 120 push down and with ratchet 101
Engagement, makes ratchet 101 descending cannot rotate, and equivalent to limiter of speed SM set mode, therefore can prevent limiter of speed 1 from automatically reseting.
Further, since offer the pivoted hole 133 in waist hole on jam plate 130, therefore, make the limiter of speed 1 still can be with up
Rotate.Specifically, after limiter of speed 1 is braked, the spacing between ratchet 101 and fork 120 is minimum, as shown in figure 4, limiter of speed 1 is up
When be not enough to allow ratchet 102 (rotating clockwise) to pass through, but due to opening up the pivoted hole 133 of waist hole, ratchet 102 on jam plate 130
By promoting jam plate 130 it can be made to vacate enough spaces will pass through toward moving right, so as to realize the upper of limiter of speed 1
OK.
When limiter of speed 1 needs to reset, operator are manipulated by cabinet, obtain the electric magnet 160 on limiter of speed 1
Electricity, its push rod 161 stretches out and the conflict bar 135 of the lower end of pushing tow jam plate 130, so as to promote jam plate 130 to make it around the 3rd connecting shaft
134 rotate counterclockwises, when conflict bar 135 contacts at the second linking arm 124 of fork 120, lock shaft 121 goes just past first
The intersecting drift angles of the lock seaming 132 of lock seaming 131, second and turn to jam plate 130 the first lock seaming 131 top, as shown in figure 5, this
When operational control cabinet withdraw the push rod 161 of the dead electricity of electric magnet 160, electric magnet 160, jam plate 130 by recovery deformation the first bullet
Property part 140 be returned to latched position, fork 120 is returned to first position, and the first lock by the second elastic component 150 of recovery deformation
Side 131 contacts at lock shaft 121 and fork 120 is locked in into first position, as shown in Figure 2.Fork 120 is released to ratchet 102
Contradict, limiter of speed 1 is resetted, due to being operated in switch board so that limiter of speed resets, therefore can avoid entering
Entering the close limiter of speed 1 of hoistway carries out the danger of Manual reset operation.
To sum up, due to the present invention prevent the automatically reset device 100 of elevator speed limitor without machine room, its have fork 120,
Push rod 110 and jam plate 130, fork 120 is articulated in limiter of speed 1 and has first position and the second position, and one end of fork 120 is consolidated
Surely there is lock shaft 121；Push rod 110 is articulated in limiter of speed 1 and corresponding with fork 120, and push rod 110 is used to promote lock shaft 121
Fork 120 is set to be moved from first position to the second position；Jam plate 130 is rotatably connected at limiter of speed 1 and can with lock shaft 121
Discretely inconsistent, it is used to for fork 120 to be locked in first position or second.Therefore, during 1 hypervelocity action of limiter of speed, limit
Swing arm 103 on fast device 1 swings and acting on push rod 110 rotates it, push rod 110 promote lock shaft 121 so that fork 120 by
First position to the second position is moved, and during this, lock shaft 121 promotes jam plate 130 to rotate, when jam plate 130 rotates certain angle
It is separated with lock shaft 121 after degree, now jam plate 130 can reply initial position and contact at lock shaft 121 again, so as to put
Bar 120 is locked in the second position, and fork 120 cannot reset, ratchet 101 by when can be pushed down by fork 120 and nibble with ratchet 102
Close, so as to prevent limiter of speed 1 from automatically reseting, with advantages below：
First, can effective brake elevator, specifically, elevator overspeed descending cause the action of limiter of speed 1 lift safety tongs so as to make
During dynamic car, counterweight may proceed to, toward upthrow, throw to peak and fall down so as to pull car up to move due to inertia, due to
With the automatically reset device 100 of limiter of speed is prevented, now limiter of speed 1 can not reset, and lift car is descending to be still braked,
Therefore the descending passenger's personal injury for causing of car or elevator components can be prevented to damage, makes the safety of machine-roomless lift more
