Specifically, the utility model discloses a technical scheme be: the electric expansion device consists of a direct current motor, a reduction gear set and an execution part; a portable direct-current 24V bidirectional motor is adopted to simulate a direct-current 220V switch machine motor, and in order to realize that the circuit voltage 220V is constant, a divider resistor is connected in series in a circuit. The motor starts to rotate (position or reverse) in a specified direction after receiving a rotation command of the control circuit in the mechanical chamber, and drives the electric expansion piece to simulate the action of the action rod and the indication rod of the switch machine through the reduction gear set. The telescopic device is made of aluminum alloy, and two sides of the head of the telescopic device are respectively provided with a magnet for timely controlling 4 magnetic switches fixed on two sides of a movable path of the telescopic device. Switch-on and switch-off through magnetism switch react the switch position to two polarity holding relay's of control inhale or fall down and simulate goat automatic switch contact state, and then realize knowing with simulator position information transfer for the mechanical chamber. The switch is connected in series in the main starting circuit to simulate the safe contact of the switch machine, the starting power supply of the simulator can be cut off at any time, and the switch is used for simulating the blocked state in the turnout conversion process, the conversion is not in place and the locking state cannot be realized. The series switch in the indicating circuit simulates the switch positioning and reverse position shifting contactor, and can also be used for 'break indicating' test.
In practice, the electric telescopic device is also connected with a control circuit, which is shown in fig. 3-4.
The existing direct current electric switch machine of the railway can be divided into the following parts according to the combination form: four-wire system single-motor, four-wire system single-motor multi-motor, six-wire system double-motor single-motor, six-wire system double-motor multi-motor and so on. The working principle of the present invention will be described below by taking the single action of the four-wire system single unit as an example.
The simulator shown in fig. 1 and 3 positions the states of the devices: the electric expansion piece is pulled in, a positioning locking magnetic suction switch (DWSB) is switched on, a positioning magnetic suction switch (DWBS) is switched on, a reverse locking magnetic suction switch (FWSB) is switched off, a reverse magnetic suction switch (FWBS) is switched off, and a position relay (WZJ 1) and a position relay (WZJ 2) keep sucking.
Fig. 3 is a schematic circuit diagram of a four-wire standalone single-action simulator (corresponding to fig. 1, both are in a state when a turnout is positioned), at this time, a turnout in a mechanical chamber indicates that a power supply passes through X3 → K2 → positioning indicates that a magnetic attraction switch (DWBS) → WZJ2, group 5 front contact → rectifier diode (forward) → WZJ2 group 1 front contact → returns to the mechanical chamber through X1, and positioning indicates that a relay magnetically attracts DBJ ×.
When the switch is operated from the positioning to the reverse position, the switch control circuit outputs direct current 220V positive (DZ 220) through X2 → WZJ1 group 1 front contact → WZJ1 group 2 front contact → WZJ1 group 3 front contact → direct current 24V bidirectional motor 1-2 → WZJ1 group 4 front contact → position relay divider resistor R1 → switch K3 → through X4 back to the switch control circuit direct current 220V negative (DF 220). At the moment, the direct-current 24V bidirectional motor rotates forwards, and the telescopic device is controlled to extend out at the speed of 20mm/s through the reduction gear set. When the magnet leaves the positioning indication magnetic attraction switch (DWBS), the positioning indication magnetic attraction switch (DWBS) is switched from an on state to an off state, the positioning indication excitation circuit is switched off, and the positioning indication relay in the mechanical chamber is enabled to lose magnetism and fall DBJ ↓; the positioning locking magnetic suction switch (DWSB) is similarly disconnected, and preparation is made for the reverse steering positioning circuit. The expansion piece continues to extend until the locking magnet is close to the reverse locking magnetic attraction switch (FWSB) and the reverse shows the magnetic attraction switch FWBS, and the reverse locking magnetic attraction switch (FWSB) and the reverse shows that the magnetic attraction switch FWBS is rapidly turned from off to on. Because the switch-on of the reverse position locking magnetic suction switch (FWSB), two position relay pole switching circuits are formed: the positive voltage of the direct current 220V (DZ 220) returns to the negative voltage of the direct current 220V (DF 220) through X2 → WZJ1 group 1 front contact → WZJ1 group 2 front contact → flip latch magnetic attraction switch (FWSB) → WZJ1 coil 2-1 → WZJ2 coil 2-1 → voltage divider resistor R2 → K3 → through X4. The WZJ1 and WZJ2 rotating poles fall down, the power supply circuit of the direct current 24V bidirectional motor is cut off, the electric expansion piece stops extending movement, and the electric expansion piece is kept in a reverse locking state.
Turn-on flip indicates circuit: the turnout in the mechanical chamber indicates that the power supply passes through X3 → K1 → flip indicates that the magnetic attraction switch FWBS → WZJ2 rear contact of group 6 → rectifier diode (reverse) → WZJ2 rear contact of group 2 → returns to the mechanical chamber through X2, and the flip indicates that the relay is excited and attracted FBJ ≠ by magnetic attraction.
When the circuit is finished, the device is in a state of inverting each device as shown in fig. 2: the electric expansion piece extends out, the positioning locking magnetic attraction switch (DWSB) is switched off, the positioning indicates that the magnetic attraction switch (DWBS) is switched off, the reverse position locking magnetic attraction switch (FWSB) is switched on, the reverse position indicates that the magnetic attraction switch (FWBS) is switched on, and the position relay 1 (WZJ 1) and the position relay 2 (WZJ 2) keep falling.
The above contents do the utility model discloses the simulation switch turns to the theory of operation of counterpointing and locking from the location, turns to the theory of operation of location by counterpointing here the same, no longer gives unnecessary details.
In the figure 3, K1 and K2 simulate the contact functions of ZD6 series switch machine displacement contactors 01-02 and 03-04 respectively, and can be used for simulating the switch machine 'off representation' test. K3 simulates the function of ZD6 series switch machine safety contact 05-06, can cut off the action circuit of the simulator at any time, simulates the state that the switch is blocked and can not be switched to the bottom, and can realize the interlocking condition test that the idle 13 seconds has no position and represents the indoor switch-squeezing alarm.
The quick-acting magnetic attraction switch with stable contact is adopted in the stroke circuit, so that the phenomenon that the just-established turnout indication circuit is cut off due to the fact that the indication switch is cut off due to vibration after a common stroke switch is used for cutting off a starting power supply is avoided.
Fig. 4 is a schematic diagram of a six-wire dual-motor dual-action simulator circuit (composed of 4 independent simulators), which is added to fig. 3 in two aspects: the method comprises the steps that necessary interlocking conditions for checking the switching of a front movable switch machine to the right position of a rear movable switch machine circuit are needed, and the checking circuit is formed by connecting joint conditions of front movable switch simulator position relays 2 (WZJ 2) 1-4. And after all turnouts are switched in place, the position information of each turnout is connected in series to form a turnout indication excitation circuit. When any equipment fails, the turnout can be cut off to indicate an excitation circuit, so that the turnout indicates that the relay loses magnetism and falls down, and the 'failure-safety' principle is realized. The circuit schematic diagrams of other switch machine combination forms are similar, and are not described again.
In a word, the utility model discloses develop according to ZD6 series goat and control circuit theory of operation, give direct current 24V two-way motor work after with control circuit direct current 220V partial pressure during the operation, drive the expansion bend through reduction gear group and stretch out or draw in. The magnetic attraction switch is controlled by utilizing the magnet arranged on the head of the telescopic device to control the positioning reversal locking and representation of the two sides of the telescopic path, and the two polarity maintaining position relays are controlled to switch, so that firstly, the outdoor equipment state is reported to the mechanical room, secondly, the working circuit of the direct current motor and the position relay is cut off, thirdly, a circuit is built for the next switching, and fourthly, the polarities of the direct current motor and the rectifier diode are switched. Through structure and circuit optimization, the direct current electric switch can achieve the function consistent with that of a direct current electric switch of ZD6 series under the condition of no need of an additional power supply, and meets the requirements of various interlocking tests. The operation is convenient, and the wiring mode is completely consistent with that of the existing point switch; the power consumption is low, and the energy is saved and the environment is protected; small, lightly easily carry, reduce the human input, practice thrift construction cost.
