Detailed Description
The following describes an elevator rescue device according to the present invention in further detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims.
Referring to fig. 1 and 2, an elevator rescue device is based on an integrated elevator control system, for example, the integrated elevator control system is a default system (equipped with NICE 3000-B4 type interface board), and is a rescue circuit for short-circuiting a safety loop in the integrated elevator control system, and a current inflow end of the rescue circuit is connected to a current outflow end K4-P09 at an emergency 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 (such as MCTC-MCB-C3) in the integrated elevator 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 rescue switch S1 is closed, the rescue circuit shorts the safety loop. When the elevator is in fault pause, the safety loop is in a disconnected state, and passengers press a rescue switch S1 arranged on an elevator control box to conduct a rescue circuit for short-circuiting the safety loop; at the moment, the elevator integrated control system controls the elevator to run to the door zone closest to the elevator, and then the elevator door is opened, namely the car door and the landing door are opened, so that passengers can safely evacuate. When the elevator arrives at the flat floor, the safety loop is disconnected, and the short circuit risk is prevented. Of course, it should be appreciated that the present invention provides an elevator rescue apparatus that can also be used in other elevator integrated control systems (e.g., foreign olys, express, flux, or domestic new-time systems, etc.).
Further, the rescue circuit further comprises a first relay KMS1, a second relay KMS2 and a third relay KMS 3; wherein, the first relay KMS1 (for example, a 24V dc relay) includes 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 (e.g. a 24V dc relay) includes a third coil and a second normally closed contact. One end of the first coil is connected with a signal position of an upper door area of a terminal row or a connector or an interface board of the elevator control cabinet, and the other end of the first coil is connected with an upper door area signal interface SCB-FL1 of a UCMP board in the elevator control cabinet; one end of the third coil is connected with a lower gate area signal position of the terminal block or the connector or the interface board, and the other end of the third coil is connected with a lower gate area 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 the K7-03 pin (upper door zone 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 the upper door zone signal interface SCB-FL1 of the UCMP board (e.g., MCTC-SCB-a 1); the current inflow end of the third coil is connected with a K7-04 pin (a lower door zone signal input point) of a connector of an 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. Persons skilled in the art will recognize that the pins K7-03 and K7-04 are connected to the output terminals of the upper gate area photoelectric switch and the lower gate area photoelectric switch, respectively. Referring to fig. 1 and 4, the current inflow end of the second coil is connected to the current outflow end 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 a rescue switch S1 through a first traveling 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 traveling 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 passengers encounter elevator faults, situations that the passengers forget to press the rescue switch S1 due to panic or press buttons in the elevator in a mess can occur, therefore, in a specific embodiment, the elevator rescue device further comprises a rescue prompting module, and when the safety loop is disconnected, the elevator integrated control system controls the rescue prompting module to prompt the passengers to press the rescue switch S1 in a voice broadcast mode.
The utility model discloses an elevator rescue device's safe line short circuit and the approximate theory of operation of disconnection as follows:
when the elevator breaks down, the safety loop is disconnected, the passenger presses the rescue switch S1, the rescue switch S1 is closed, the rescue circuit is connected, the safety loop is in short circuit, at the moment, the elevator integrated control system controls the elevator to move to the nearest door area, 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 electrified, the normally open contact of the second relay KMS2 is closed, and the safety loop is still short-circuited at the moment; meanwhile, the rescue switch S1 has a self-reset function, so that the rescue switch S1 is turned off after being reset; after the elevator moves to the door zone, the photoelectric switches of the upper door zone and the lower door zone are simultaneously shielded, 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 respectively output high level 24V to an upper door zone interface SCB-FL1 and a lower door zone interface SCB-FL2 of the UCMP board, at this time, 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, at this time, the rescue circuit is disconnected, the elevator can automatically open the door at the leveling position, the rescue is finished, the disconnected state of the safety circuit is kept, the fault of the safety circuit is reported, and no external call or internal call signal is responded.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, the changes are still within the scope of the present invention if they fall within the scope of the claims and their equivalents.
