Abstract
The utility model relates to a station change error-proof locking device which is an electromechanical linkage an induction testing circuit, a signal amplifying circuit, and an AC/DC converting circuit is connected with a drive circuit in series. One end of a lever is provided with an armature, the other end of the lever is provided with a locking pin, the lower part of the armature is provided with an electromagnetic coil, and a spring is sheathed on the armature. When the armature approaches to the electromagnetic coil, the spring is in the state of energy storage. The utility model changes technological equipment and adds an error-proof locking device, so that the electric shock accident can be fundamentally avoided.
Description
The utility model belongs to a kind of door lock assembly.
In the electric operating personal injury, because pedaling to climb by mistake by mistake, operating personnel's mistake bumps, cause accounting for more than 70% of accident generation.When becoming on the platform operation such as the operating personnel on pedaling, if fail all to break the primary side high voltage source, electric shock accidents takes place very easily.Experience from the more than ten years, stop the generation of this type of accident, only the rules and regulations (i.e. " software ") with strictness can not tackle the problem at its root, have only from the angle of human engineering technology and start with, consider people, machine, three factors of environment simultaneously, writing an article on technical equipment (i.e. " hardware "), is the key point that solves this type of problem.
The purpose of this utility model provides a kind of station change error-proof blocking device, and it can fundamentally stop on the change platform electric shock accidents to take place.
The purpose of this utility model is achieved in that it is the lock of dynamo-electric interlock, comprises control circuit and mechanical lock two parts.
1, the annexation of control circuit:
Induction testing circuit, signal amplification circuit, the straight translation circuit of friendship and drive circuit series connection, wherein drive circuit is formed by driving warning circuit and driving the lock pin circuit, and the two is the relation of " non-", drives the lock pin circuit and is made up of electromagnetic coil and triode;
2, the structure of mechanical lock:
One end of lever is an armature, and the other end is a lock pin, and the bottom of armature is an electromagnetic coil, is with spring on the armature, armature is when the electromagnetic coil, and spring is the energy storage state, is the pin door bolt below the lock pin, and pin has latched block, at ordinary times, lock pin is stuck on the block of pin door bolt, and door is not opened.
Operating principle is: mechanical lock is installed on the wicket that becomes the platform fence, is in blocking at ordinary times, and promptly door is not opened.The induction probe portion is installed near the transformer primary side high tension terminal.When operating personnel all do not disconnect the high pressure of transformer one side, be that the transformer primary side is when having high pressure to exist, then respond to detection circuit and can induce voltage, after this signal amplified through amplifier, again through rectification, its output was a high level, enter the warning circuit in the drive circuit, warning circuit starts, and reminds operating personnel with chimes of doom, checks whether operational procedure is correct.Because driving warning circuit is " non-" relation with driving the lock pin circuit, warning circuit starts, and the lock bolt circuit does not start, and lock bolt is not moving, also is in blocking, and operating personnel can't enter the change platform, thereby avoid electric shock accidents to take place.
If operating personnel can not induce voltage on the induction detection circuit after the high pressure of transformer one side is all disconnected, and are low levels until the output of handing over straight translation circuit yet, at this moment drive warning circuit and do not start, and the lock pin circuit start, electromagnetic coil gets, generate an electromagnetic field, armature is descending, near electromagnetic coil, and the other end of lever, lock pin is up, leave the block of lock bolt, lock bolt can be twitched, and operating personnel can open door.
The utility model compared with prior art, it is started with from technical equipment, increases anti-misoperation locking device, the generation of fundamentally stopping electric shock accidents.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is an electric theory diagram of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
Fig. 3 is a mechanical lock structure schematic diagram of the present utility model.
Referring to Fig. 1,2, the induction testing circuit is made up of probe M and FET V1 source follower, two amplifier A1, A2 form two-stage amplifier, the source electrode of V1 is connected on the input of A1, the diode D1 of amplifier A3 and the output that is connected on it forms the straight translation circuit of friendship, after its output circuit meets phase inverter F1, divide two-way, one the tunnel is the lock pin drive circuit, electromagnetic coil L1 is connected on the colelctor electrode of triode T1, and another road is the warning drive circuit, the base stage of the output termination triode T2 of phase inverter F2, the collector connecting relay J1 of T2, its node connects language chip.
Referring to Fig. 3, an end of lever 6 is an armature 5, and the other end is a lock pin 7, and the bottom of armature is a circuit coil 3, is with spring 4 on the armature, and armature is when the electromagnetic coil, and spring is the energy storage state, is pin door bolt 2 below the lock pin, and pin has latched block 8.At ordinary times, lock pin is stuck on the block of pin door bolt, and promptly door is not opened.The 1st, base.
Operating principle is: when operating personnel all disconnect the high pressure of transformer one side, be that the transformer primary side is when having high pressure to exist, then respond to detection circuit and can induce voltage, this voltage is after V1 detects, the electrode utmost point is exported a voltage signal, this signal is through A1, be input to the A3 wave detector after the amplifier that A2 forms amplifies and carry out detection, be the direct current high level then at the B point, after F1 and F2 are anti-phase, the T2 conducting, relay J 1 adhesive, power supply is added to voice alarm circuit through the J1 contact, and loudspeaker send the chimes of doom of " have electric danger please don't be close " and remind operating personnel to check whether operation is correct.Because B point is high level, so F1 is output as low level, T1 can not conducting, and no current passes through among the electromagnetic coil L1, and armature 5 is failure to actuate, and stopping bar 7 is in blocking, and lock bolt 2 can not be opened, and operating personnel can't enter the change platform, thereby avoid the electric shock accidents generation.
After if operating personnel all disconnect the high pressure of transformer one side, can not induce voltage in the detection, V1 is output as low level, is low level also at the B point behind A1, A2, A3, and then F1 is output as high level, the T1 conducting, have electric current to pass through among the electromagnetic coil L1, armature 5 moves downward, and drives stopping bar and moves upward, this moment, lock bolt 2 can paddling, and operating personnel can open door.In this case, because F1 is output as high level, so F2 is output as low level, the T2 conducting, J1 is failure to actuate, and the voice alarm circuit non-transformer does not produce audio alert.
