Abstract
The utility model discloses an interlocking safe control device of an elevator light curtain. The interlocking safe control device of the elevator light curtain comprises three relays, wherein the first relay K1 and the second relay K2 are output contacts and are connected in series, the third relay K3 is used for motoring whether the contacts of the K1 and the K2 have an adhesive phenomenon, and if the adhesive phenomenon exists, the third relay K3 is cut off. The output of the interlocking safe control device of the elevator light curtain adopts an interlocking method, and the risk of clamping a person caused by the adhesion of the output contacts of the relays is avoided.
Description
Technical field
The utility model relates to a kind of interlocking safety control setup of elevator light curtain.
Background technology
Whether normally the light curtain that uses at present mostly is a relay output, there is no to detect contact circuit, when the relay output contact goes wrong, can have certain risk.
The utility model content
The utility model purpose is the interlocking safety control setup that a kind of elevator light curtain is provided for the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
The interlocking safety control setup of a kind of elevator light curtain of the utility model comprises 3 relays, and wherein first, second relay K 1, K2 are output contact, by being connected in series; The 3rd relay K 3 is used for supervision K1, and whether the contact of K2 has adhesion phenomenon, and if any adhesion, the 3rd relay K 3 namely disconnects.
Described first, second relay K 1, K2 can also be for being connected in parallel.
The utility model will be exported the mode that adopts interlocking, can solve the folder people risk that produces because of the adhesion of relay output contact.
