The number of landing door electrical contacts 9 generally corresponds to the number of floors of the house, one for one, and there are n floors of the house, and there are generally n landing door electrical contacts, and thus there is one landing door electrical contact 9 for each floor.
The detection device for door lock disconnection detection is used for detecting whether a door lock loop of an elevator landing door of elevator equipment is disconnected, and comprises a machine room operation device and a car roof operation device. The machine room operating device is installed in the machine room, and the car top operating device is installed on a door lock contact of an elevator floor.
The machine room operating device is used for being electrically connected in series in a safety loop of the elevator equipment, and comprises a first probe (not shown), an electric bell 13, a normally open switch 14 and a second probe (not shown). One end of the first probe is used as a contact for detection, the other end of the first probe is electrically connected with one end of the second probe after being electrically connected in series with the electric bell 13 and the normally open switch 14, and the other end of the second probe is used as a contact for detection. Therefore, the whole machine room operating device can be electrically connected in series in the safety loop at any time through the first probe and the second probe so as to carry out subsequent detection operation.
The normally open switch 14 may be one of a button switch and a relay switch, as long as the machine room operating device is in an off state in a non-detection state. By operating the normally open switch 14, the normally open switch 14 is closed when the door lock open inspection detection device detects the door lock open inspection. The first probe, the electric bell, the normally open switch and the second probe can be electrically connected by adopting a flexible lead.
The car top operating device is used for being connected in parallel with the landing door corresponding to the floor where the elevator is located after the machine room operating device is electrically bridged on the safety loop.

Detection device for elevator layer door lock disconnection inspection needs two elevator maintenance personal to cooperate when detecting, and one elevator maintenance personal is located inside the computer lab, and another elevator maintenance personal is located the car top of elevator. The elevator maintenance personnel who is located elevator machine room inside at first closes normally open switch 14 to utilize first probe and second probe short circuit with the safety circuit, therefore trigger electric bell 13 and send the sound, the elevator maintenance personnel who is located elevator car top hears the sound that electric bell 13 sent this moment, press the maintenance button on elevator car top, maintenance button control elevator's car reciprocates in the well, when arriving the layer door that awaits measuring, loosen maintenance button, the car of elevator stops the operation, utilize third probe and fourth probe to this layer door lock circuit cross-over, if the lock circuit is normal, then emitting diode 15 can not change, if the break-off trouble appears in the lock circuit, then emitting diode 15 sends light, and help elevator maintenance personnel to lock the fault point fast.
The utility model discloses loaded down with trivial details in the detection process to elevator lock, need the successive layer point by point to carry out the problem that detects elevator layer door lock, make the safety circuit short circuit in the computer lab respectively through two maintenance personal, the mode that makes cross-over connection elevator layer door lock return circuit on the sedan-chair top carries out the detection of lock, it is complicated to have solved the detection method, the problem of overlength consuming time, and whether the door lock contact return circuit switches on through emitting diode comes reaction, it is more directly perceived on the one hand, more quick locking fault point, on the other hand has reduced the potential safety hazard of elevator in maintenance process. The utility model discloses a detection device is used in elevator layer door lock disconnection inspection through computer lab operating means and sedan-chair top operating means, has realized the quick inspection to elevator layer door lock return circuit, can improve the efficiency of inspection, improves the security of inspection.
For traditional lock disconnection inspection (traditional inspection mode needs going of elevator maintenance personal successive layer point by point to look into, the fault detection to the lock disconnection is comparatively loaded down with trivial details, in-process at the inspection need be at the computer lab with the safety circuit short circuit, check the cross-over connection of lock contact again, every operation one deck of elevator is with the safety circuit of short circuit once, and cross-over connection lock contact, the meeting switches on elevator safety circuit, the elevator has certain safety risk, the while inspection still needs to consume a large amount of time, especially to the high-rise elevator on twenty thirty layers, the problem that inspection efficiency is low is more obvious), the utility model discloses an elevator layer door lock disconnection inspection is with detection device's advantage lies in: through computer lab operating means and sedan-chair top operating means, realized the quick inspection to elevator layer door lock circuit, can improve the efficiency of inspection, improve the security of inspection.
It should be noted that, after the door lock loop is short-circuited, although a loop is provided for the safety loop, the passing current of the light emitting diode 15 is only 1 to 2mA, so that the current for driving the elevator to run cannot be reached, the problem of danger generated during the operation of the elevator cannot be worried about, and the potential safety hazard is reduced.
The third probe, the light emitting diode 15, the adjustable resistor 16 and the fourth probe can also be electrically connected by flexible wires. The flexible lead is convenient for detection of maintenance personnel due to the flexibility of the flexible lead.
In other embodiments, the adjustable resistor 16 may not be provided, but in this case the ceiling operating device loses its adjustable function, so it is preferable to provide the adjustable resistor 16. The elevator maintenance personnel can adjust the resistance value of the adjustable resistor 16 according to the voltage of the safety loop, and the situation that the detection equipment is damaged and potential safety hazards are increased due to the fact that the voltage of the safety loop is too large and the light-emitting diode 7 is broken down by too large current is avoided.
Consequently, elevator layer door lock disconnection detection device accessible adjustable resistance 16 for the inspection adapts to the lock return circuit of different voltage, prevents that emitting diode 15 from being punctured, has enlarged the application scope of this device on the one hand, and on the other hand has prolonged the life of this device, and this device is through two elevator maintenance personnel complex modes, and the duties of each division have broken through traditional inspection mode, make actual product inspection mode simple, and is efficient, save time, improve the security, easy operation's advantage.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
