Description
Technical field
The invention belongs to the safeguard protection instrument technical fields of traction elevator, and in particular to one kind has monitoring elevator car
The bidirectional speed limiter of compartment accidental movement function.
Background technique
Currently, there is no to electricity by the existing elevator standard GB788-2003 in China " elevator manufacture and installation technical specification of security "
The accidental movement of terraced carriage provides protection and requires, cause now elevator be in improper in brake and other components
Lead to that lift car accidental movement accident upward or downward occurs when opening layer door and hall door under state, passenger is be easy to cause to exist
The personal safety accident sheared when passing in and out elevator door.In order to solve this safety problem, national standard body's approval is certainly
Start No. 1 modification list of execution GB7588-2003 " elevator manufacture and installation technical specification of security " from July 1st, 2016, wherein
Most important modification content is the protection requirement increased to accidental movement of elevator cage, i.e., forcing to increase on all elevators prevents
Accidental movement of elevator cage protective device.According to current elevator mechanical & electrical technology, which is answered
It should be made of carriage accidental movement monitoring device and braking executive device two parts.
Single Description of Revision is modified for No. 1 for reply GB7588-2003 " elevator manufacture and installation technical specification of security ", at present
The broad form of brake actuator has description in Chinese Patent Application No. 201520597337.5 " gradual bidirectional rope gripper "
Prevent accidental movement of elevator cage brake protection mechanism.And in the prior art, accidental movement monitoring device is typically all by electricity
Sub- component and control panel are programmed to, i.e., by monitoring elevator cab door interlocking signal and door area inductor signal, pass through
The logic analysis of control panel, once signal occurs abnormal (accidental movement occurs in judgement), signal monitoring apparatus issues brake signal
Electric triggering arrestment mechanism is obtained to the electromagnet of brake actuator and implements braking, makes the rapid stop of the lift car of accidental movement.
However, the precondition that the monitoring device of above-mentioned monitoring accidental movement of elevator cage uses is that elevator is unable to power loss.Once elevator
Power loss, the monitoring device cannot then play a protective role.In addition, if braking executive device uses the control mode of power loss braking,
Although the accidental movement of lift car can be prevented, braking executive device is not in the case where accidental movement occurs for carriage, also
The elevator of power loss is braked, this braking is actually inevitably malfunction.It is multiple after braking executive device movement
Position is a fairly cumbersome thing, although the external braking executive device having can be accomplished to automatically reset to mechanical part,
It is required according to standard criterion, electric safety switch must carry out hand-reset.Therefore, the region bad in electric power thus supplied, braking
Executive device will be acted frequently, and maintenance personal will constantly carry out electrical reset, and lift car is be easy to cause to close people's
Accident.If braking executive device using electric braking control mode, can prevent the unexpected of lift car from moving to greatest extent
It is dynamic, avoid the trouble of above-mentioned described braking malfunction and frequent recovery.But in the event of a loss of power, the meaning that lift car occurs
Outer movement just can not be monitored and brake.

Specific embodiment
As depicted in figs. 1 and 2, the bidirectional speed limiter with monitoring accidental movement of elevator cage function of the present invention,
It is that progress structure is improved on the basis of the LD130 type bidirectional speed limiter of Foshan City power east elevator accessory Co., Ltd production.It should
Bidirectional speed limiter includes bracket 1 and the fifth wheel 2, ratchet 3, shift fork 31, the arrestment mechanism trigger assembly, four that are mounted on bracket 1
A block 5 and block interference component.Shift fork 31 and ratchet 3 are integrally formed and link with arrestment mechanism trigger assembly.Four blocks 5
The wherein one side for corresponding to the rotation axis of fifth wheel 2 equidistantly and waiting angles that fifth wheel 2 is set.The interference component is main
Be made of support 61, electromagnet 62 and electromagnetic core 63: support 61 is fixed on the side of shift fork 31；Electromagnet 62 is fixedly mounted
On support 61；Electromagnetic core is plugged in electromagnet 62 and passes through the hole on shift fork 31, and its motion profile and fifth wheel 2
Axis is parallel.Arrestment mechanism trigger assembly is mainly made of two brake arms 41 and two drag-lines 42: two brake arms 41 are distinguished
It is resiliently arranged on bracket 1 and is linked with dialling 31；One end of each drag-line is connect with one of brake arm 41, another
End triggering accidental movement of elevator cage arrestment mechanism.
1 course of work of the invention is as follows:
When lift car operates normally, electromagnet obtains electric and sucks electromagnetic core, makes the end side of electromagnetic core far from survey
Speed takes turns and keeps certain gap with the block on fifth wheel.
When elevator host brake, lock under brake power loss.If brake has enough brake force, traction steel
When having enough frictional force (non-slip) between cord and traction sheave, accidental movement will not occur for lift car.At this point, even if
Electromagnet power loss discharges electromagnetic core, and reset spring pushes electromagnetic core to fifth wheel, since electromagnetic core and block are in circle
There is no relative movements in circumferential direction, therefore bidirectional speed limiter can't trigger arrestment mechanism (such as rope brake, safety tongs, folder rail
Device etc.) movement.
When elevator host brake or when there is abnormal running, lock under brake power loss, electromagnet also power loss
Make electromagnetic core close to fifth wheel.At this point, if not having between elevator brake brake force deficiency or traction steel-cable and traction sheave
When enough frictional force (skiddings), accidental movement can occur for lift car.Governor rope is drawn by force under frictional force effect at this time
Dynamic fifth wheel rotation, and the rotation of fifth wheel drive block move in a circumferential direction and with electromagnetic core making contact, thus
It pushes shift fork rotation and rotates brake arm, to trigger arrestment mechanism movement by drag-line, realize accidental movement of elevator cage
Braking.
It should be noted that bidirectional speed limiter of the present invention, elevator car speed monitoring and operating principle and
LD130 type bidirectional speed limiter is the same, equally has uplink and downlink hypervelocity monitoring function, details are not described herein.And its carriage is surprisingly moved
Dynamic monitoring function is then Purely mechanical, is not limited by power grid and other conditions, is truly realized no matter which kind of reason causes
Accidental movement of elevator cage, instantaneous monitoring and braking executive device can be triggered, make the rapid stop of lift car.
In addition, the present invention can also pull drag-line, safety dress of the machinery triggering for uplink and downlink overspeed protection by brake arm
It sets, makes it have uplink and downlink hypervelocity monitoring function.
