Abstract
The utility model discloses an interlocked-circuit short-circuit preventing device for controlled elevator door, comprising a circuit with the functions of signal reception and chronography. The utility model is characterized in that the signal input end of the circuit of the device is respectively connected with the hall door switch signal and the sedan door switch signal of the interlocked-circuit of the controlled elevator door; the circuit has the functions of discriminating the communicating time differences of the hall door switch and the sedan door switch. The circuit of the device mainly comprises a single-chip computer. The utility model has the following advantages: if the elevator is provided with the device, maintainers don't need to worry about accidents initiated because of forgetting to remove the short-circuit of the door interlock, the utility model is a good helper to the maintainer, and the interlocked-circuit short-circuit preventing device for controlled elevator door has the advantages of low cost and convenient installation, etc.
Description
Technical field
The utility model relates to the anti-short-circuit device in an elevator control cabinet gate interlock loop, belongs to the elevator field.
Background technology
At present, elevator is as a kind of vehicle of vertical transport, the inevitable frequent people and goods that has passes in and out car, if elevator causes system to think that loop of the door lock just often by mistake for a certain reason, inevitable startup by force, the people is clipped in produces shearing between gate and the Room door, make the people injured or dead.Annual man-hour of dying owing to this type of accident has generation, and promptly in a single day short circuit takes place gate interlock, even under the situation of opening the door, elevator in the same old way can mule carriage.This type of accident is serious accident, and account for the sizable ratio of elevator accident, and the accident gate interlock that the behavior of gate interlock short circuit mostly occurs in the machine room elevator control cabinet when taking place detects the loop, the reason of the improper short circuit of gate interlock mainly contains 3 aspects at present: 1, reason is equipment itself, early the old-fashioned elevator that still has a great deal of that dispatches from the factory still adopts all-in-one-piece door switch, so there is the possibility of adhesion of gate interlock contact or short circuit in this part elevator, but still have possibility on the long in the back control linkage line, or the gate interlock short circuit that on controller, causes because of other apparatus failure because of destruction of insulation short short circuit.Maloperation when 2, keeping in repair is when the maintenance elevator, sometimes for gate interlock in easy to operate or the interim short circuit electrical control cubicles of needs.Elevator is walked maintenance, but the maintainer need change between normal condition and inspecting state in order to keep in repair purpose sometimes, and forgotten gate interlock sometimes at this moment by short circuit, or after maintenance finishes, forgotten to take down the gate interlock shorting stub, and to leave away after directly forwarding elevator to automatic operation, this moment, elevator also can the normal switch door, but if if door is the folder people when a little, and system thinks that door has closed, inevitable startup by force, and Ci Shi elevator has just become " killing machine " who brings on a disaster at any time so.Because the interim short circuit during maintenance is necessary sometimes, thereby this situation also is difficult to eliminate fully.3, reason is the illegal operation of maintenance person, obstructed phenomenon when leading to sometimes sometimes owing to gate interlock.And when because gate interlock contacts when bad, elevator can not mule carriage, even oppressive, and some elevator reparing factories are in order to save trouble, and directly with elevator door interlocking short circuit in electrical control cubicles, and makes the elevator can mule carriage.Though this kind off-square method for maintaining is dangerous, can temporarily cover the fault of elevator door interlocking.
Summary of the invention
The purpose of this utility model is the problem that exists at above-mentioned elevator and design-calculated judges that to the electrical point of corresponding gate in the electrical control cubicles and Room door whether gate or Room door or two kinds of doors are by short circuit.If absolute synchronization on both times, then can judge at gate and Room door contact has short circuit, and makes elevator out of service.Because this device is irrelevant with the elevator master control system, so, become an independently safety system, therefore, more can not lose efficacy because of the master control board program confusion of control housing.
The purpose of this utility model is achieved in that a kind of elevator control cabinet gate interlock loop prevents short-circuit device, signal receives by having, the circuit of clocking capability is formed, it is characterized in that: the signal input part of the circuit of this device is connected with Room door switch signal, the gate switch signal in gate interlock loop in the elevator control cabinet respectively, and circuit has the function of differentiating Room door switch, gate switch turnon time difference.
Short-circuit device is prevented in above-mentioned elevator control cabinet gate interlock loop, and the circuit of this device mainly is made up of one-chip computer.
The utlity model has following advantage: elevator has been installed this device, and the maintainer does not again worry because of having forgotten the accident that the gate interlock shorting stub causes of dismantling.Having low cost, be convenient to advantages such as installation, is maintainer's " good assistant ".
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model schematic circuit diagram.
The specific embodiment
As shown in Figure 1, short-circuit device is prevented in a kind of elevator control cabinet gate interlock loop, signal receives by having, the circuit 2 of clocking capability is formed, it is characterized in that: the signal input part of the circuit 2 of this device is connected with Room door 3 on-off signals, the on-off signal of gate 4 in the elevator control cabinet 1 respectively, and circuit 2 has the Room of differentiation door 3 switches, the function of 4 switch connection time differences of gate.Circuit 2 mainly is made up of one-chip computer 5.The principle of work of this device is such, utilized gate and Room door at closing time, whose characteristic after whom earlier its contact conducting has, these characteristics are principle cores of this device, by the turn-off time respectively timing of the circuit in the device to switch gate and Room door, if two times are the same, loop short circuit then, otherwise loop short circuit not then.And the principle of other decision gate interlock system is not seen gate and the Room door characteristics at closing time contact conducting successively of utilizing.Elevator has been installed this device, and it is maintainer " good assistant " because of having forgotten the accident that the gate interlock shorting stub causes of dismantling that the maintainer does not again worry.This device has low cost, is convenient to advantages such as installation.
Claims (2)
1, the anti-short-circuit device in a kind of elevator control cabinet gate interlock loop, signal receives by having, the circuit (2) of clocking capability is formed, it is characterized in that: the signal input part of the circuit of this device (2) is connected with Room door (3) on-off signal, gate (4) on-off signal of elevator control cabinet (1) inside door interlock circuit respectively, and circuit (2) has the Room door (3) of differentiation switch, the function of gate (4) switch connection time difference.
