Embodiment

The technical solution of the utility model is described further with reference to figure and specific embodiment.

A kind of anti-short circuit detection of elevator belt loop of the door lock of the present utility model and control device by MCB electric life controllers (1), KMT hall door door locks contact (2), KMJ car door locks contact (3), KMM loop of the door lock safety relay (4), DZS door zone positions are opened Close (5), SMZ safety detection modules (6), SCD door-closing in-place switch (7) and SOD enablings location switch (8) composition.Such as Fig. 1 institutes Show,

The MCB electric life controllers (1) switch with the SMZ safety detection modules (6), the DZS doors zone position respectively (5), the SCD door-closing in-place switch (7), the SOD enablings location switch (8), the KMM loop of the door lock safety relay (4), the KMT hall doors door lock contact (2) is connected with the KMJ car door locks contact (3)；The MCB electric life controllers (1) are The processing of all signals of elevator and control centre；

The KMT hall doors door lock contact (2) is composed in series elevator door lock loop with KMJ car door locks contact (3), while respectively The high-voltage signal turned off or on to electric life controller transmission loop of the door lock；

The KMM loop of the door lock safety relay (4) gathers the KMT hall doors door lock contact (2) and the KMJ gates door Contact (3) loop high-voltage signal is locked, and loop of the door lock status signal is sent to electric life controller, while door is absorbed by its coil Induced electricity on lock loop circuit, at the same its contact series elevator work brake circuit in, if loop of the door lock safety after Electrical equipment is not operating, and elevator service brake can not be opened, and ensures elevator safety；

DZS doors zone position switch (5) is that elevator door zone position is identified, while to the SMZ safety detections Module provides loop signal；

The SMZ safety detection modules (6) receive the door lock detection trigger signal that electric life controller is sent and with DZS doors area Position switch signal is combined to bridge loop of the door lock；

The SCD door-closing in-place switch (7) judge whether elevator door lock loop is in closed mode, and to elevator controlling Device sends loop of the door lock door-closing in-place control signal；

The SOD enablings location switch (8) judges whether elevator door lock loop is in open mode, and to elevator controlling Device sends loop of the door lock enabling control signal in place.

When elevator be normally transported to certain layer arrive at a station enabling after, MCB electric life controllers first determine whether KMT hall doors door lock on controller All whether contact, KMJ car door locks contact loop high-voltage input signal and KMM loop of the door lock safety relay control inputs signal Disconnect, at the same with SOD enabling location switches control signal carry out logic judgment, if door-opened elevator location switch signal effectively and When KMT hall door door lock contacts and effective any one high input voltage signal of KMJ car door locks contact loop, electric life controller thinks door There is short circuit phenomenon in lock loop, forbid elevator to be again started up, if KMM loop of the door lock safety relay control input signals do not break Open, then think door lock safety relay exception, while forbid elevator to be again started up.

After elevator, which is normally transported to certain layer, arrives at a station enabling in place, above-mentioned each component actuation is normal, in SOD enabling location switches Under the premise of signal and DZS door zone position signals are effective, MCB electric life controllers export detection trigger signal and give SMZ safety detections Module, after bridging loop of the door lock by safety relay contact in SMZ safety detection modules, judge that KMJ car door locks loop is It is no normal, if SMZ safety detection modules act, KMT hall door door locks contact high pressure letter can also be received on MCB electric life controllers Number, then system thinks that KMJ car door locks loop has short circuit failure, forbids elevator to be again started up.

When elevator is in NOT gate zone position, automatic running pattern is re-powered or overhauled when turning automatic mode, is meeting elevator Under entry condition, first automatic triggering enabling signal (because elevator cage door is equipped with car door lock, ensures only to open MCB electric life controllers On the premise of KMJ car door locks contact), and judge whether KMJ car door locks contact loop is shorted, if working as MCB elevator controls After device processed sends enabling signal, KMJ car door locks contact does not disconnect, then system thinks that KMJ car door locks contact loop is present Short circuit failure, forbids elevator to be again started up, and can be just again started up after elevator detection is normal.

When elevator starts or run, MCB electric life controllers must gather SCD door-closing in-place switch control signal, KMM door locks Safety relay control signal, KMT hall door door lock contacts and KMJ car door locks contact loop high-voltage signal, to ensure that elevator is pacified Row for the national games, when controller detects above-mentioned abnormal signal, system is out of service immediately.

After elevator reaches certain layer of enabling, if MCB electric life controllers detect this layer of SOD enabling, signal is not operating in place, But other safety signals are normal (KMT, KMJ door lock contact loop and KMM door lock safety relays all disconnect after door-opened elevator), are System can automatically continuously export multiple switching gate signal, and such as SOD enablings, signal is still not operating in place, but other safety detection signals are still Normally, the MCB electric life controllers automatic shield floor layer instructs.If detecting door-opened elevator location switch signal effective When KMT hall door door lock contacts and also effective any one high input voltage signal of KMJ car door locks contact loop, electric life controller is thought There is short circuit phenomenon in loop of the door lock, forbid elevator to be again started up.

As shown in Fig. 2 electric life controller collection hall door and car door lock loop high-voltage input signal, and receive switch gate and arrive Position and independent loop of the door lock safety relay control signal carry out logic judgment, ensure elevator before starting every time to loop of the door lock Carry out Autonomous test, it is ensured that elevator safety operation.

The anti-short circuit detection of elevator belt loop of the door lock and control device are under elevator automatic running pattern before each run Loop of the door lock is all detected, it is ensured that elevator operation is safer, and simultaneity factor circuit structure is simple, and detection part uses Safety relay, ensure its product reliability, therefore can be used on various types of elevators.

Described above is only the utility model preferred embodiment.It should be pointed out that the ordinary skill for the art Member for, on the premise of the utility model technical principle is not departed from, some improvement and modification can also be made, these improve and Modification should also be considered as the scope of protection of the utility model.
