Abstract
The utility model discloses an elevator safety controller, including the control motor just, the contactor 2JC of reversal, 1JC, normally closed travel switch 3TA2 and normally open contact 3JC3 back of connecting in parallel, one termination three phase current is one phase, the other end meets with contactor 2JC2 of the normally closed contact of 2JC, 2JC 2's the other end and normally closed safety control button 3TA 1's normally closed terminal connection, another termination relay 3JC of safety control button 3TA1 connects another phase of three phase current, the normally closed contact 3JC1 of relay 3JC connects between control button 2QA and contactor 2 JC. The utility model discloses ground feeding personnel's safety can be ensured, the occurence of failure is stopped.
Description
The utility model relates to a kind of safety governor of building hoist.
Existing elevator generally adopts pulley, utilizes winch folding and unfolding steel cable to realize the lifting of hanging basket, and the control of hanging basket lifting is by layer personnel control upstairs.In the actual use, often because misoperation, the charging personnel also do not walk out elevator basket, and upstairs the layer operation personnel just start winch, and hanging basket is risen, and accident such as cause casualties.
But the purpose of this utility model is to provide a kind of safety control hanging basket to rise, and stops the elevator safety governor that accident takes place.
Technical solution of the present utility model is:
A kind of elevator safety governor, comprise the contactless switch 2JC that control winch motor is just changeing, the contactless switch 1JC of control winch motor counter-rotating, it with the difference of prior art is: normally closed travel switch 3TA2 is with after the open contact 3JC3 of relay 3JC is in parallel, one termination three phase mains, one phase, the normally closed contact 2JC2 of the other end and contactless switch 2JC joins, normally closed contact 2JC2 the other end be connected with the normally closed binding post of normally closed safety control button 3TA1, connect another phase of three phase mains behind another relay termination 3JC of safety control button 3TA1, the normally closed contact 3JC1 of relay 3JC is connected between control button 2QA and the contactless switch 2JC.
Open contact one termination three phase mains one phase of safety control button 3TA1, the other end is connected to zero-power line with after electric bell is connected.
Only after ground charging personnel clicked the safety control button, upstairs layer personnel could connect hanging basket rising control circuit to the utility model, thereby can guarantee ground charging personnel's safety, and the accident of stopping takes place.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the circuit diagram of an embodiment of the utility model.
Fig. 2 is application example figure of the present utility model.
A kind of elevator safety governor 1 is installed on the bottom of elevator 12, it comprises contactless switch 2JC and hanging basket 8 rising control buttons 10 (2QA) that control winch motor 2 is just changeing, the contactless switch 1JC and the hanging basket 8 decline control buttons 9 (1QA) of 2 counter-rotatings of control winch motor, normally closed travel switch 5 (3TA2) is with after the open contact 3JC3 of relay 3JC is in parallel, one termination three phase mains, one phase, the normally closed contact 2JC2 of the other end and contactless switch 2JC joins, normally closed contact 2JC2 the other end be connected with the normally closed binding post of normally closed safety control button 3 (3TA1), connect another phase of three phase mains behind another relay termination 3JC of safety control button 3TA1, the normally closed contact 3JC1 of relay 3JC is connected between control button 10 (2QA) and the contactless switch 2JC.Also be connected to signal lamp 4 in the circuit.
Open contact one termination three phase mains one phase of safety control button 3 (3TA1), the other end is connected to zero-power line with after electric bell 6 is connected.Be still waiting to promote material 7, layer operation device 11 upstairs among the figure.
Principle of work of the present utility model is; Travel switch 5 (3TA2) is normally closed, when hanging basket 8 declines touch travel switch 5, its normally closed point disconnects, relay 3JC does not have electric current to pass through, and its normally closed contact 3JC1 disconnects, open contact 3JC2 closure, at this moment signal lamp 4 glimmers under starter R effect, no matter upstairs how the layer operation personnel press hanging basket rising button 10, because 3JC1 disconnects, contactless switch 2JC does not have electric current to pass through, its open contact is also opened, motor 2 can not start, and at this moment has only after charging personnel in ground put into hanging basket 8 to material 7 to be hoisted, when walking out hanging basket and clicking safety control button 3, electric bell is connected, the personnel of layer operation upstairs of announcement can promote materials handling, 3JC energising simultaneously, normally closed contact 3JC1 closure, upstairs the layer operation personnel get final product starter motor 2, realize to promote material, normal battle of the 3JC3 of relay 3JC, 3JC2 disconnects, and indicator lamp extinguishes.So just realized the safe in operation of elevator.
Claims (2)
1, a kind of elevator safety governor, comprise the contactless switch 2JC that control winch motor is just changeing, the contactless switch 1JC of control winch motor counter-rotating, it is characterized in that: normally closed travel switch 3TA2 is with after the open contact 3JC3 of relay 3JC is in parallel, one termination three phase mains, one phase, the normally closed contact 2JC2 of the other end and contactless switch 2JC joins, normally closed contact 2JC2 the other end be connected with the normally closed binding post of normally closed safety control button 3TA1, connect another phase of three phase mains behind another relay termination 3JC of safety control button 3TA1, the normally closed contact 3JC1 of relay 3JC is connected between control button 2QA and the contactless switch 2JC.
2, elevator safety governor according to claim 1 is characterized in that: open contact one termination three phase mains one phase of safety control button 3TA1, the other end is connected to zero-power line with after electric bell is connected.
