Drawings
Fig. 1 shows an example of an electrical schematic diagram of an elevator safety protection device according to the invention.
Detailed Description
The structure and principle of such a device will be apparent to those skilled in the art from the following further description of the invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment provides an elevator safety protection device, including elevator control panel, prevent the maloperation socket and prevent the maloperation plug-in components, wherein, prevent that maloperation socket and elevator control panel signal link to each other, prevent that maloperation socket is equipped with the slot of N equidistant settings, prevent maloperation plug-in components and be equipped with N-1 contact pin, N-1 contact pin of preventing maloperation plug-in components can cooperate with arbitrary N-1 adjacent the slot simultaneously to switch over the operating condition of elevator control panel, N is more than or equal to 3 positive integer.
When the two contact pins are matched with the two adjacent slots, the elevator control panel is in a normal working state, and the elevator control panel can operate the elevator to work normally.
When the two contact pins are matched with the other two adjacent slots, the elevator control panel is in a maintenance state and cannot operate the elevator.
Thereby because the contact pin of preventing maloperation socket inserted normal condition just can not insert the contact pin of maintenance state, the interlocking function of preventing maloperation plug-in components has been realized, when the maintenance state, operating personnel will prevent maloperation plug-in components and insert in the slot of preventing two maintenance states of maloperation socket, make the elevator control panel can not operate the elevator, prevent that operating personnel or other people from causing the incident at the maloperation elevator during maintenance, effectively guaranteed the work safety during elevator maintenance.
For example, as shown in fig. 1, the anti-misoperation socket is added to the control cabinet of the conventional elevator, and a 3PIN terminal is used as three slots, when the anti-misoperation pins are inserted into the 1 st slot and the second slot, the elevator is in a normal working state, when the anti-misoperation pins are inserted into the 2 nd slot and the 3 rd slot, the elevator is in a maintenance state at the moment, because the anti-misoperation plug is 2PIN, the anti-misoperation plug can not be matched with the 2 nd slot and the 3 rd slot when being matched with the 1 st slot and the 2 nd slot, on the contrary, the anti-misoperation plug can not be matched with the 1 st slot and the 2 nd slot when being matched with the 2 nd slot and the 3 rd slot, can prevent operating personnel's maloperation like this, guarantee that the elevator can not have the state of all normally switching on under the maintenance state, guarantee installer's safety, this kind prevents that maloperation plug-in components operation is used also very conveniently by mistake of slow-witted formula.
In a preferred embodiment, also shown in connection with fig. 1, for three of the described slots, one of the slots is connected to one input port of the zener barrier AN40, the other slot is connected to the other input port of the zener barrier AN40 and then grounded and connected to the 501-terminal power supply negative terminal, and the output port of the zener barrier AN40 is connected to the I0 terminal of the elevator control board.
In addition, the elevator control panel of the elevator safety protection device is also provided with a plurality of ports, and each port is connected to each corresponding functional switch after being connected with the Zener safety barrier, such as an S32 door closing button, an S31 door opening button, an S7 fire switch and the like.
In addition, the elevator safety protection device also comprises a redundancy design of elevator safety protection, wherein the redundancy design of the elevator safety protection comprises various command input signal circuits, output signal circuits, a fault judgment circuit, a bypass standby circuit and the like of the elevator, and the command input signal circuits, the output signal circuits, the fault judgment circuit, the bypass standby circuit and the like are respectively connected to an input signal end, an output signal end, a fault judgment end and a bypass standby end of an elevator control panel.
In a preferred implementation mode, a program verification can be added to a circuit for inputting instruction maintenance and normal state detection, so that when normal and maintenance plug-ins are carried out, incoming signals are verified to ensure that maintenance and normal simultaneous connection cannot occur, two input signals are effective simultaneously, validity and accuracy of the input signals can be judged after verification, if errors exist, the input signals are judged to be in fault, fault alarm is output simultaneously, and therefore the purpose of ensuring safety is achieved.
The procedure verification procedure is as follows:
1) when the elevator has no shaft scale (the shaft self-learning is not performed), the Er18 fault is reported under the automatic state, and the elevator is forbidden to run.
2) When the elevator is detected in the factory, the hoistway will be self-learned, resulting in the factory having hoistway data, adding special parameter FX-46 (which is only authorized to be debugged using the factory code), setting FX-46 to 1234, clearing the existing hoistway data, and FX-46 automatically reverting to 0.
3) An I0 input point is additionally added to the control cabinet to be used as installation mode detection, the control cabinet is in short circuit with I0 or X5 during factory configuration, the elevator can only be overhauled and operated, the Er91 fault is reported automatically, operation is forbidden (no matter whether well scales are learned or not), and after installation is finished, the I0 short circuit plug-in elevator can be automatically operated only by removing the I0 short circuit plug-in elevator.
The above, only for the concrete implementation of this utility model, but the scope of protection of this utility model is not limited to this, and any person skilled in this technical field is in the technical scope of this utility model discloses, according to the technical scheme of this utility model and novel design add in equal replacement or change, all should be covered in the scope of protection of this utility model.
