The present invention can be arranged on the left and right sides of elevator hoistways pit car position, be installed on lift car track.This
Invent and drive safety relay KA actions for trigger device, safety relay KA controls left electric cylinder 31 and right electric cylinder 32 flexible
Action, so as to control a left side to horizontally rotate plate weldment 2, left buffer 10,90 degree of rotations are done along left rotation shaft 4, the right side horizontally rotates
Plate weldment（It is not shown）With right buffer（It is not shown）It is as the same, pit overhaul space is increased when overhauling elevator is descending, is played
Protective effect.
Concrete operating principle is to act limit switch SSAQ, not operating in the conduction state in home, elevator is not transported
OK, contactless contactor KMY is in release conditions, the normally closed point conductings of contactless contactor KMY.Only need the foldable spats of lift car
Plate is acted, i.e. toe guard of elevator car step switch SSH1 is connected, toe guard of elevator car step switch SSH1 opened points closure, or elevator key
Spoon step switch SAF2 opened point action conductings, or first floor hall door step switch SAS1（Or other layers of hall door step switch) normally opened
Point action conducting, safety relay（KA）Action.
When safety relay KA is acted, the conducting of safety relay KA all opened points, normally closed point release, now not between
Power-off source PC-UPS to the left power by electric cylinder 31 and left electric cylinder 32, and left electric cylinder 31 and left electric cylinder 32 shrink, left horizontal turn
Dynamic plate weldment 2, the right rotary shaft for horizontally rotating plate weldment and corresponding buffer along respective phase side make 90 degree of rotations, work as arrival
Left electric cylinder action location switch SLZD and the action location switch ZLYD actions of right electric cylinders, left electric cylinder 31 and a left side during setting position
The stopping of electric cylinder 32 acts, and is maintained at 90 degree and stops off-position and puts.
Meanwhile when safety relay KA is acted, safety relay KA opened points conducting, time relay KT obtains electric meter
When, safety alarm HAJ obtains electric alarm, and safety alarm HAJ can be sound and light alarm, or be alarm bell or alarm lamp.When logical
Cross setting value time relay KT delays to disconnect, warning device HAJ dead electricity stop alarms.
When safety relay KA is acted, the normally closed points of safety relay KA disconnect, and cut off elevator normal operation signal, now
Safety relay KA opened points turn on, and elevator can enter to overhaul up-downgoing operation after turning inspection travel.Such as safety relay not
Action, elevator, which turns maintenance, can not then carry out inspection travel.
As shown in figure 4, during elevator normal operation（The present invention is not operating, and safety relay is also not operating, at toe guard of elevator car
In retrieving position), now the normally closed point conductings of safety relay KA, a left side stop stop device reset switch SSF2 and stop stop device with right
Reset switch SSF1 is turned on, and toe guard of elevator car reset switch SSH2 is normally closed point conducting.Now, safety return circuit of the invention is：
--- limit inferior switch SLDL --- the normally-closed contact KA9 of safety relay the 4th --- is left to stop stop device reset switch to access point A
SSF2 --- stops stop device reset switch SSF1 --- toe guard of elevator car reset switch SSH2 --- and picks out point B, then seal in electricity in the right side
Terraced safety return circuit, elevator safety loop connection, elevator can normal operation.
When overhauling elevator is run（Present invention action, safety relay KA adhesives, toe guard of elevator car are in withdrawal/act bit
Put), now the normally closed points of safety relay KA disconnect, and when the present invention acts in place, stop device step switch SSZ1 and a left side are stopped in the right side
Only stop device step switch SSZ2 is turned on, and stop device reset switch SSF2 is stopped on a left side and the right stop device reset switch SSF1 that stops breaks
Open, the second limit switch SLDT1 is reinstated.Now safety return circuit of the invention is：Access point A --- limit inferior switch SLDL ---
Stop stop device step switch SSZ1 and --- stop stop device step switch SSZ2 --- the second limit switch SLDT1 --- and pick out in a left side in the right side
Point B, elevator safety loop is sealed in, elevator safety loop connection, elevator can inspection travel；When maintenance goes downwards to the second limit switch
SLDT1, elevator stop downwards, and now elevator can only be run up by the second maintenance upstream switch SBPU2 maintenance to departing from the
Two limit switch SLDT1.
When overhauling elevator is run（If not operating, safety relay KA adhesives of the invention, toe guard of elevator car, which is in, to be withdrawn/moves
Make position), now the normally closed points of safety relay KA disconnect, and because the present invention is not operating in place, stop device step switch SSZ1 is stopped on the right side
Stop stop device step switch SSZ2 with a left side to disconnect, now only switched by promptly connecting power button in the maintenance of SBG and second
Row button switch SBPU2, promptly runs up, descending invalid, so as to ensure maintenance safety.
The up button switch SBPU2 of the up maintenance of button switch SBPU1 and second of first maintenance is the up button of maintenance
Auxiliary contact.
Reset switch above refers to the normally closed point to inductive switch, and step switch is the opened point to inductive switch.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Creative work can is needed to make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
