Detailed Description
The elevator rescue device provided by the invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Advantages and features of the invention will become more apparent from the following description and from the claims.
Referring to fig. 1 and fig. 2, an elevator rescue device is based on an elevator integrated control system, for example, the elevator integrated control system is a mohnak system (matched with NICE 3000-B4 type interface board), and is a rescue circuit for shorting a safety loop in the elevator integrated control system, wherein a current inflow end of the rescue circuit is connected with a current outflow end K4-P09 at a sudden stop button of a control cabinet in the safety loop; the current outflow end of the rescue circuit is connected with a safety detection interface X25 of a main control board (for example, MCTC-MCB-C3) in the elevator integrated control system; the rescue circuit is connected with a rescue switch S1, and the rescue switch S1 is arranged on the elevator control box; when the rescue switch S1 is closed, the rescue circuit shorts the safety circuit. When the elevator is in a halt state due to faults, the safety circuit is in an off state, and passengers turn on a rescue circuit for shorting the safety circuit by pressing a rescue switch S1 arranged on the elevator control box; at this time, the elevator integrated control system controls the elevator to travel to the nearest door zone, and then opens the elevator door, i.e., opens the car door and landing door, to allow passengers to evacuate safely. When the elevator reaches the flat floor, the safety loop is disconnected, and the risk of short circuit is prevented. Of course, it should be appreciated that the elevator rescue device provided by the present invention may also be used in other elevator integrated control systems (e.g., foreign austs, dashing, power systems, or domestic new time systems, etc.).
Further, the rescue circuit further comprises a first relay KMS1, a second relay KMS2 and a third relay KMS3; the first relay KMS1 (for example, a 24V direct current relay) comprises a first coil and a first normally-closed contact; the second relay KMS2 (for example, a 110V ac relay) includes a second coil and a normally open contact; the third relay KMS3 (for example, a 24V dc relay) includes a third coil and a second normally closed contact. One end of the first coil is connected to a terminal strip of the elevator control cabinet or an upper door zone signal of a connector or an interface board, and the other end of the first coil is connected with an upper door zone signal interface SCB-FL1 of a UCMP board in the elevator control cabinet; one end of the third coil is connected with a lower door zone signal of the terminal strip, the connector or the interface board, and the other end of the third coil is connected with a lower door zone signal interface SCB-FL2 of the UCMP board; for example, referring to fig. 2 and 3, the current inflow end of the first coil is connected to pin K7-03 (upper gate signal input point) of the connector of the interface board (e.g., MCTC-KCB-B4) of the elevator control cabinet, and the current outflow end of the first coil is connected to upper gate signal interface SCB-FL1 of the UCMP board (e.g., MCTC-SCB-A1); the current inflow end of the third coil is connected with a K7-04 pin (lower door zone signal input point) of a connector of the interface board of the elevator control cabinet, and the current outflow end of the third coil is connected with a lower door zone signal interface SCB-FL2 of the UCMP board. The related staff in the field can know that the K7-03 pin and the K7-04 pin are respectively connected with the output ends of the upper door zone photoelectric switch and the lower door zone photoelectric switch. Referring to fig. 1 and 4, the current inflow end of the second coil is connected to the current outflow ends K4-P09 at the emergency stop button of the control cabinet in the safety loop; the current outflow end of the second coil is connected with one end of the normally open contact; the current outflow end of the second coil is also connected with one end of the rescue switch S1 through a first following cable L1; the other end of the normally-open contact is connected with one end of the first normally-closed contact and one end of the second normally-closed contact; the other end of the rescue switch S1 is connected with the safety detection interface X25 through a second following cable L2, and the rescue switch S1 has a self-resetting function; the other ends of the first normally-closed contact and the second normally-closed contact are connected with a safety detection interface X25.
It should be appreciated that when a passenger encounters an elevator failure, a situation may occur in which the passenger forgets to press the rescue switch S1 or presses a button in the elevator in a messy manner, and therefore, in a specific embodiment, the elevator rescue apparatus further includes a rescue prompt module, and when the safety circuit is disconnected, the elevator integrated control system controls the rescue prompt module to voice broadcast to prompt the passenger to press the rescue switch S1.
The general working principle of shorting and disconnecting the safety line of the elevator rescue device is as follows:
When the elevator breaks down, the safety loop is disconnected, a passenger presses the rescue switch S1, the rescue switch S1 is closed, the rescue circuit is conducted, the safety loop is short-circuited, at the moment, the elevator integrated control system controls the elevator to run to a door zone closest to the elevator, and then the elevator door is opened to enable the passenger to safely evacuate.
Specifically, after the rescue switch S1 is closed, the second coil is energized, the normally open contact of the second relay KMS2 is closed, and the safety loop is still shorted at this time; meanwhile, the rescue switch S1 has a self-resetting function, so that the rescue switch S1 is disconnected after being reset; when the elevator moves to the door zone, the photoelectric switches of the upper door zone and the lower door zone are shielded at the same time, referring to fig. 3, when the photoelectric switches of the upper door zone and the lower door zone are shielded, K7-03 and K7-04 can output high level 24V to an upper door zone interface SCB-FL1 and a lower door zone interface SCB-FL2 of the UCMP board respectively, at the moment, the two ends of the first coil and the third coil are electrified, the first normally closed contact and the second normally closed contact are disconnected, the rescue circuit is disconnected, the elevator can automatically open a door at a flat floor position, rescue is finished, the state of the safety circuit disconnection is maintained, the safety circuit fault is reported, and any external calling signal and internal calling signal are not responded.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, it is within the scope of the appended claims and their equivalents to fall within the scope of the invention.
