Summary of the invention
To above deficiency; The purpose of this invention is to provide a kind of monitoring and protecting device of simple in structure, safe and reliable abnormal operation of elevator, when elevator door is in door opening state and slips car up or down; This device can trigger the elevator stopping device action; Thereby failure-free stop car avoids the elevator operation of opening the door the passenger is caused to shear injury.
The monitoring and protecting device of abnormal operation of elevator of the present invention comprises layer door guide rail bracket and car door rail frame, and said car door rail frame is provided with the car door rail that can supply gate to slide, and on the said layer door guide rail bracket switch is installed and re-packs; The side direction sunken inside towards gate that said switch re-packs is formed with the banded groove of beating; The said length direction of beating groove is consistent with the line of travel of gate, trigger switch is installed, on the gate when gate begins to open; The switch driving lever of trigger switch begins to get into to be beaten in the groove; In the process that gate is opened, the switch driving lever of trigger switch moves beating groove, when car moves up and down unusually in the process that gate is opened; The switch touch switch driving lever that re-packs triggers stopping device action stop car through trigger switch.
Being equipped with on the said car door rail frame can be along the gate link plate of car door rail slip, said gate link plate captive joint gate, trigger switch captive joint gate link plate.
Be fixedly connected with at least one support that re-packs on said switch re-packs, all supports that re-pack are fixedly mounted on the layer door guide rail bracket.
Said trigger switch is fixedly mounted on the switch bracket, said switch bracket captive joint gate.
Said trigger switch is fixedly mounted on the switch bracket, said switch bracket captive joint gate link plate.
Be connected through cable electrical between said trigger switch and the stopping device, said stopping device is wire holder, guide rail clamper or drg.
When car was in layer door position, the height of the switch driving lever of said trigger switch was consistent with the height of beating groove.
Beneficial effect of the present invention: on the layer door guide rail bracket of the present invention switch is installed and re-packs, the side towards gate that switch re-packs is provided with the banded groove of beating, and trigger switch is installed on the gate; When gate began to open, the switch driving lever of trigger switch begins to get into to be beaten in the groove, in the process that gate is opened; The switch driving lever of trigger switch moves beating groove, when car moves up and down unusually in the process that gate is opened, and the switch touch switch driving lever that re-packs; Trigger stopping device action stop car through trigger switch; Like this, directly the possible car that slips up and down unusually of various elevator door open modes is monitored, and trigger the stopping device action through simple physical construction; Thereby avoid the injury to the people, this device does not influence the normal operation of elevator simultaneously.
