Specific implementation mode
Now using the traction sheave of elevator host as common fixed pulley, carry out the fixed pulley driving described in the present invention will be described in detail
Device applies the concrete structure and operation principle in long-range jiggering deliverance apparatus.
As shown in Figure 1 to Figure 3, long-range jiggering deliverance apparatus of the present invention, mainly by the traction of an elevator host
Take turns 1, gear set, two ratchet mechanisms and two ratchet drive component compositions.
The gear set is made of a driven gear wheel 21 and two driver pinions 22, wherein：Driven gear wheel
21 are fixed on the side of the traction sheave 1 of elevator host and co-axial linkage.Two driver pinions 22 are arranged in driven
It is simultaneously engaged with driven gear wheel 21 both sides of gear wheel.
Each ratchet mechanism is made of a ratchet 41 and a detent 42, wherein：Ratchet 41 is fixed on
The side of one driver pinion 22 simultaneously passes through a 3 co-axial linkage of wrapping device, the correspondence of detent 42 ratchet 41
Setting.
Each ratchet drive component is mainly moved along a straight line group by 5, sprung returns of a resilient push component
Part 6 and a driving device composition.Resilient push component corresponds to a ratchet and is arranged and is pressed on the peripheral region of the ratchet.Elasticity
One end of linear reciprocating motion component is connect with resilient push component.Driving device is driving the sprung return to move along a straight line
Component acts.Wherein：
Each resilient push component 5 is mainly by 51, compressed springs 52 of a push rod housing and a push rod
53 compositions.51 one end open of push rod housing, other end closing.Compressed spring 52 is placed in push rod housing 51.Push rod 53, which is placed in, to be pushed away
In rod sleeve and one end stretches out outside push rod housing under the action of compressed spring and is pressed on the peripheral region of ratchet 41 always.
Each sprung return linear motion component 6 is mainly oriented to 61,62 and of resetting spring of cylinder body by one
One slide bar 63 forms.Cylinder body 61 is oriented to perpendicular to push rod housing 51 to be arranged.Resetting spring 62, which is set to, to be oriented in cylinder body 61.It is sliding
Bar 63 is slidably arranged in the guide cylinder body of 62 side of resetting spring, and one end stretch out in be oriented to cylinder body 61 it is outer and with
Push rod housing 51 is fixedly connected.
Each driving device is a traction rope 7, which connect with the other end of a slide bar 63.This
Outside, wherein a traction rope 7 is around being located on a sheave 8, the direction that this traction rope applies tractive force is made to be led with another
The direction of messenger is identical.Two traction ropes all extend to outside the Room.
The course of work of long-range jiggering deliverance apparatus of the present invention is as follows：
When elevator is in accidental conditions, two driver pinions do not engage with driven gear wheel.
When needing to carry out long-range jiggering uplink to lift car, so that the wrapping device on the left of Fig. 1 is acted makes left side ratchet
With the driven pinion coaxial linkage in left side, jiggering tractive force F1 then is applied to traction rope, then traction rope makes slide bar be oriented to
Sliding in cylinder body, the push rod being connect with slide bar push ratchet wheel, ratchet wheel to drive driver pinion and driven canine tooth rotation
It is dynamic, to make the traction sheave of elevator host be rotated synchronously with driven gear wheel and drive car uplink, then release jiggering traction
Power F1, then slide bar initial position is returned under the action of resetting spring, push rod compresses ratchet under the action of compressed spring, and stops
Pawl then limits the drawback movement of ratchet；Jiggering tractive force F1 is applied to traction rope again, then makes car uplink again.Pass through
Above repetitive operation, you can by the flat bed region above car jiggering to car, to smoothly expansion rescue.
When needing to carry out long-range jiggering downlink to lift car, then so that the wrapping device on the right side of Fig. 1 is acted makes right side spine
Then the driven pinion coaxial linkage of wheel and right side applies jiggering tractive force F2, you can by car jiggering to sedan-chair to traction rope
Flat bed region below compartment, to smoothly expansion rescue.
It should be noted that above-mentioned wrapping device can mechanically or electrically drive.Ratchet drive component
Driving device except using it is artificial apply tractive force in addition to, can also passing through other, mechanically or electrically device device is realized.
