At this point, shaft 500 is successively arranged in third axis hole, the second axis hole 312 and first shaft hole 211, the bulge loop of 500 one end of shaft
510 offset with the side of driving lever 400, and the other end of shaft 500 is matched with fastener 520, prevent shaft 500 and the to realize
One inner ring 210, the second inner ring 310 and driving lever 400 are detached from.
Referring to Fig. 1, one end of synchronous elastic component 600 is set on the first rotating wheel 200, and the other end is set to slotting
On pin 340, synchronous elastic component 600 is able to drive the second rotating wheel 300 and makees coaxial in the same direction turn with the rotation of the first rotating wheel 200
It is dynamic, remain that the first rotating wheel 200 and the second rotating wheel 300 have the tendency that synchronous rotation.Specifically, synchronous elastic component 600
It can be spring.Certainly, in other embodiments, synchronous elastic component 600 can also be tension spring, elastic string etc..
Specific in present embodiment, the first outer ring of the first rotating wheel 200 is fixed in one end of synchronous elastic component 600
On 220, and between two neighboring first spoke 230.Fixing piece is formed with for example, can protrude on the first outer ring 220
240, one end of synchronous elastic component 600 is indirectly secured on the first outer ring 220 by being fixed on realization on fixing piece 240.It is fixed
Part 240 includes interconnecting piece 241 and fixed part 242, and the protrusion of interconnecting piece 241 is formed on the inner wall of the first outer ring 220, fixed part
242 are located on interconnecting piece 241, and one end of synchronous elastic component 600 is fixed on fixed part 242.
One end of return springs 700 is set on driving lever 400, and the other end is set on pedestal 100.Synchronous elastic component
600 coefficient of elasticity is less than the coefficient of elasticity of return springs 700, therefore return springs 700 are deformed the external force of needs
It is bigger than the external force that synchronous elastic component 600 is deformed needs, when the first rotating wheel 200 drives the second rotating wheel 300 is synchronous to turn
It moves until driving lever 400 can not be made to rotate immediately when the second spoke 330 receives the blocking of telescopic rod 410 of electromagnet.Specifically,
Return springs 700 can be spring.Certainly, in other embodiments, return springs 700 can also be tension spring, bullet
Property rope etc..
Specific in present embodiment, the quantity of return springs 700 is two, and two elastic component return units are axisymmetric
It is set to the opposite sides of driving lever 400.Therefore, can be adapted for driving lever 400 to rotate forward or invert.Two return springs 700
Coefficient of elasticity having the same can be in the collective effect of two return springs 700 when driving lever 400 is without other external forces
It is lower to be in balance reset state.
Two action pieces 800 are axisymmetrically set to the opposite sides of pedestal 100, and one end of action piece 800 is set to
On driving lever 400, the other end with the arrestment mechanism of elevator for being connected.When action piece 800 is pulled with the rotation of driving lever 400
When, the arrestment mechanism that action piece 800 triggers elevator carries out stop.Specifically, action piece 800 can be drawstring, two drawstring axis
It is symmetrically located at the opposite sides of pedestal 100.
The above-mentioned detection device 10 for mechanical detection accidental movement of elevator cage has at least the following advantages:
It is mounted on computer room ground by pedestal 100, the first rotating wheel 200, the second rotating wheel 300 and driving lever 400 can be rotated
Ground is set on pedestal 100, and the carriage run up and down drives the positive/negative rotation of the first rotating wheel 200 by wirerope 20.
Referring to Fig. 1, when lift car leveling opening, 410 auto-extending of telescopic rod of electromagnet, and assume that it extend into phase
Between adjacent two the second spokes 330, and it is located in the range of the rotation covering of the second spoke 330, it is assumed that bolt 340 is also at two
Between first spoke 230.
If wirerope 20 drives the first rotating wheel 200 to rotate counterclockwise referring to Fig. 2, accidental movement occurs for carriage at this time
(rotating clockwise similarly), the first rotating wheel 200 pass through synchronous elastic component 600 and the second rotating wheel 300 are driven coaxially to rotate in same direction.
After first rotating wheel 200 and the second rotating wheel 300 turn an angle, the telescopic rod 410 of the second spoke 330 and electromagnet occurs
Collision.
Referring to Fig. 3, since the coefficient of elasticity of synchronous elastic component 600 is less than the coefficient of elasticity of return springs 700,
The force ratio that return springs 700 remain stationary driving lever 400 is larger, and the second rotating wheel 300 can not temporarily be such that driving lever 400 sends out
Raw rotation, prevents it from continuing to rotate by driving lever 400 instead.First rotating wheel 200 can only overcome the elastic force of synchronous elastic component 600 into
The rotation of one step.
Referring to Fig. 4, until bolt 340 collides with the first spoke 230, to drive the second rotating wheel 300 by force
It coaxially rotates in same direction, and then driving lever 400 is driven to rotate, the rotation of driving lever 400 is with pulling action part 800, and trigger action part 800 is another
The arrestment mechanism of the elevator of one end realizes carriage stop.
When carriage shutdown continues to walk ladder, the telescopic rod 410 of electromagnet retracts automatically, the first rotating wheel 200 and second turn
The arbitrarily rotation of driving wheel 300 not will drive the rotation of driving lever 400, and driving lever 400 can not obtain in movement, will not export elevator stopping letter
Number.Therefore it may be implemented to be not required to change old terraced control system and carry out detection accidental movement using mechanical system.
Particularly, when lift car leveling opening, the telescopic rod 410 of electromagnet is just tangent with the second spoke 330, i.e., directly
Into state shown in Fig. 2.At this time if the direction of carriage towards " telescopic rod 410 of the second spoke 330 shock electromagnet " occurs
Small-scale movement (not constituting accidental movement still), then the first rotating wheel 200 can only overcome synchronous elastic component 600 elastic force and list
Solely rotation, but since the moving distance is smaller, the first spoke 230 can not collide always with bolt 340, the second rotating wheel
300 remain motionless.Driving lever 400 and action piece 800 can not will be transferred in movement, so that the brake of elevator will not be made
Structure movement can effectively reduce the generation of malfunction, and the distance of carriage small range movement is only according to two first spokes 230
Angular distance specify.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
