Description

Technical Field

[0001] The utility model relates to the technical field of elevator escape, in particular to an automatic alarm and anti-door-picking warning prompt device for an elevator. Background Art

[0002] Elevators have gradually become an important means of transportation for everyone to enter and exit buildings, but elevator failures can cause passengers to be trapped in the elevator car. For ordinary passengers, being trapped in the elevator car will make them feel particularly scared and they will want to escape from the car as soon as possible, so the trapped passengers will try to force open the elevator door to escape.

[0003] Elevators produced before 2003 had no anti-door prying restrictions, and passengers could easily pry open the elevator door from inside the car. This would cause passengers to fall into the elevator shaft through the gap between the door and the shaft wall, resulting in casualties. Utility Model Content

[0004] The utility model aims to provide an automatic alarm and anti-door prying warning prompt device for an elevator, which solves the problem in the prior art that elevators produced before 2003 have no anti-door prying restrictions, and passengers can easily pry open the elevator car door from the car, which will cause the passengers to fall into the elevator shaft through the gap between the car door and the shaft wall, causing casualties.

[0005] To achieve the above-mentioned purpose, the utility model provides an elevator automatic alarm and anti-door pickpocketing warning prompt device, including a control cabinet interface board, an SMQ elevator upper door area relay, an XMQ lower door area relay, a SW operation contactor auxiliary contact, a JX elevator maintenance relay, a BB voice player, a DH elevator car emergency telephone relay, an X1 terminal, an X3 terminal, an X9 terminal and an alarm unit, the SMQ elevator upper door area relay, the XMQ lower door area relay, the SW operation contactor auxiliary contact and the JX elevator maintenance relay are connected in sequence and are all connected to the control cabinet interface board, the X1 terminal is arranged between the control cabinet interface board and the SMQ elevator upper door area relay, the X3 terminal is arranged between the control cabinet interface board and the XMQ lower door area relay, the X9 terminal is arranged between the control cabinet interface board and the JX elevator maintenance relay, and the BB voice player is arranged on the DH elevator car emergency telephone relay.

[0006] Among them, the elevator automatic alarm and anti-door picking warning prompt device also includes an AN elevator car emergency rescue telephone button, and the AN elevator car emergency rescue telephone button is connected to the DH elevator car emergency telephone relay.

[0007] Among them, the models of the SMQ elevator upper door area relay, the XMQ lower door area relay, the JX elevator maintenance relay and the DH elevator car emergency telephone relay are all HH52P.

[0008] Among them, the working voltage of the SMQ elevator upper door area relay, the XMQ lower door area relay, the JX elevator maintenance relay and the DH elevator car emergency telephone relay are all DC24V.

[0009] Among them, the DH elevator car emergency telephone relay is connected to the SMQ elevator upper door area relay, the XMQ lower door area relay, the SW operation contactor auxiliary contact and the JX elevator maintenance relay.

[0010] The utility model is an automatic alarm and anti-pick door warning device for elevators. When the elevator fails during normal operation (non-maintenance state), the elevator car does not stop at the leveling area, the SMQ elevator upper door area relay, the XMQ lower door area relay and the JX elevator maintenance relay do not operate, and the elevator operation contactor is released. Then, the BB voice player is triggered through the normally closed contacts of the SMQ, XMQ, JX relays and the auxiliary contacts of the SW operation contactor to start broadcasting warning reminders, and at the same time, the DH elevator car emergency telephone relay is activated, and the normally open contacts of the DH elevator car emergency telephone relay are connected, and the emergency rescue telephone button in the elevator is dialed to obtain contact with the duty room. Therefore, when the elevator fails and people are trapped, the duty room of the property company can be automatically dialed to obtain contact with the duty personnel, and at the same time, the trapped passengers are reminded by voice not to try to save themselves. Thus, the safety of the trapped passengers is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS
