Description
Technical field
The present invention relates to elevator technology, in particular to a kind of lift appliance.
Background technique
In elevator device, carriage and counterweight are arranged among liftway, are carried out respectively by car guide rail and weight guide
Guiding is hung by the traction rope being wound around on driving host, by driving the driving force of host in liftway mutually to phase
Opposite direction moves in the vertical direction.
The riding comfort of operation elevator can be improved using roller guide shoe.In recent years, in order to improve elevator ride relax
Adaptive, it is more and more using the elevator of roller guide shoe.But for the elevator for being configured with roller guide shoe, carriage is opened in leveling
Door state, when passenger passes in and out, the case where carriage will appear up-down vibration.Its main cause is that passenger passes in and out carriage and causes to sedan-chair
The load change that compartment applies causes the traction rope for hanging carriage flexibly to stretch.In general, it is big in lifting height of lift, i.e.,
It is bigger that traction rope hangs length, and when carriage is in lower floor, the up-down vibration situation can be more obvious.
If carriage vibrates up and down, the passenger in carriage can strike fear into because carriage is rocked unstable, to drop
Low ride comfort.In addition, unbalance loading caused by passenger passes in and out can gradually lead to roller guide shoe under lift car leveling stationary state
Idler wheel generates permanent deformation, to influence the comfort of elevator ride.
Bring sense of insecurity is vibrated up and down in order to eliminate the carriage, has some solutions at present.
In a patent having disclosed (103261074 B of notification number CN, 2015 days for announcing September 9 days), disclose
One kind being used for the exemplary means used in elevator device.Including at least one friction member, resistance is optionally moved into
Buddhist nun position, in damping position, friction member can be used for damping the movement of lift car associated with the device.Solenoid promotees
Dynamic device has the armature for being positioned to be suitble to vertical shift.Armature is moved up when solenoid is motivated, and friction member is moved
Enter to damp position.When solenoid is unexcited, armature quality pushes armature on downward vertical direction, to cause to rub
Component removes damping position.
Its principle is to install one group of friction damping device additional except roller guide shoe, and in lift car leveling opening, passenger passes in and out sedan-chair
During compartment, pressed down on the guide rail of carriage by the frictional force by pressing against the power of friction member electromagnetic actuator
The up-down vibration of carriage processed.
Its main problem is: needing except roller guide shoe, friction damping device is in addition arranged, including for driving friction
Electromagnetic actuator and control device of component etc., it is very complicated in structure, obviously rise in cost；Secondly, the friction damping installed additional

When device fully opens, the cam mechanism cannot be all observed directly in stop side and carriage, be also difficult to certainly contact and
Operation, so that installation and maintenance are very inconvenient.
3. the first friction member and the second friction member can be crimped slidably when gate fully opens, generates and inhibit sedan-chair
The frictional force that compartment vibrates up and down.If having personnel's disengaging, (practical experience shows that this is one during door opens or closes
The very universal phenomenon of kind), the carriage up-down vibration generated is that the vibration absorber can not overcome.
4. the structure of the cam mechanism is difficult to adjust, due to being that gate pushes it in place when opening the door, cam mechanism is to gate
It opens the door and generates resistance.If Cam Design or installation site are inaccurate, may influence to open the door in place, and door aligning device opens the door and produces
Raw larger resistance.More seriously, it may cause the damage of the even entire door gear of door motor.
5. the structure of the cam mechanism is difficult to adjust, adaptability is poor, can not easily cope with different sill gaps, i.e.,
The car door sill project different from landing sill spacing.
It, can if spring aging or failure 6. the cam mechanism is resetted using modes such as springs when gate is closed
Cam mechanism restoration unfulfillment can be generated so that carriage run when and hoistway inner part have risk of collision.
7. the cam mechanism when being in storage position, looks up in the side of carriage lifting operation, leads after the reset
It to be partially still located at except carriage range, hoistway inner part may be generated when carriage is run and hook risk.
8. two ends in door gear enabling direction are arranged in the cam mechanism, so 1 can only be arranged or be arranged in pairs
Totally 2, scalability is poor.
9. the structure of the cam mechanism is still more complicated, not enough succinctly, higher cost.
