Unit [8] is set fault and 220V AC motor [26] is not the parts of Liu worker CLG922 excavator, is that practice-training teaching arranges for convenience; Fault arranges unit [8] and is connected in the electric wiring that fault need be set; 220V AC motor [26] is the diesel motor of replaced C LG922 excavator, has reduced floor area in the function that realizes the driving generator, has also reduced the expense that engine is purchased.In addition, other each electrical equipment connects by the actual electric connection line of Liu worker CLG922 excavator, belongs to public technology, not in this narration.
Further referring to Fig. 4, the fault wiring region [33] that fault arranges unit [8] comprises lead [101] and [105], connecting terminal block [102] and [104], insulated wire [103], is placed in the upper strata of removable double-decked platform.Modal electric fault is circuit loose contact or open circuit, blown fuse, and for this reason, the circuit that needs is arranged fault disconnects, and receive respectively on the two winding line terminals at two ends.In actual being electrically connected of Liu worker CLG922 excavator, the lead that lead [101] and [105] are normally straight-through, but in teaching training apparatus, in order to impart knowledge to students conveniently, lead is disconnected, be used for fault is set, be described as follows:
In fault wiring region [33], receive respectively on two winding line terminals rows' [102] and [104] the terminal at the circuit two ends that needs arranged fault, lead [101] is divided into two-way from a winding line terminals [102]: the one tunnel is connected on another winding line terminals row's [104] the terminal with insulated wire [103] (dotting Fig. 4) from the upper strata of platform, another road is linked on the switching motherboard [42] of platform lower floor with real lead [106], be connected to behind the tandem tap [108] on another winding line terminals row's [104] the terminal, the terminal from another winding line terminals row [104] is connected on the relevant electrical equipment with true lead [105] again; On version, the insulated wire [103] that connects from the upper strata of platform is in parallel with the lower floor from platform with the branch road that the switch true lead [106], [107] and the switching motherboard [42] is in series.Like this, the insulated wire of platform topsides [103] just represents the route of line, and lead [106], [107] and switch [108] that whether circuit is really connected by platform lower floor determine, when switch [108] is connected, the lead of lower floor [106], [107] but the normal flow excess current, when switch [108] disconnected, the open wires of lower floor was finished the fault setting.On switch [108] and corresponding lead [101], [105], [106], [107], and on the insulated wire [103] the numbering mark is arranged, being convenient to teacher arranges fault and checks, and whether the student need open a way or wrong with the relevant lead of multimeter measurement according to phenomenon of the failure, judges the where is it fault by situation about detecting.
Only having drawn the switch of 4 leads among Fig. 4, is for its principle is described compactly, and the number of switches that arranges in the actual practical traning platform is set as required, and the cross connection of circuit can be set.The fault that can arrange on the Liu worker CLG922 excavator practical traning platform of having made has: can't start, full car does not have electricity, the swing arm lamp does not work, swing arm lamp and the vehicle frame lamp is being got lines crossed, loudspeaker do not ring, oil cut-off valve is obstructed, fuel level sensor does not show, wiper can not be worked.
Please referring to Fig. 5, the 220V AC motor is represented with electric symbol M 1, is the diesel motor of replaced C LG922 excavator, has reduced floor area in the function that realizes the driving generator, has also reduced the expense that engine is purchased; The 24V Dyn. represents that with electrical symbol G1 this Dyn. is actual to be threephase alternator, the DC voltage of output ripple behind three phase rectifier; The 24V battery pack is represented with electrical symbol BT1; Negative switch is represented with S3; Ignition switch represents that with SW ignition switch SW has two pairs of electrical contacts, represents with S1 and S2 respectively.The principle of power supply unit is described as follows:
When needing to use actual training device, the negative switch of closing earlier S3 after finishing using, in time disconnects negative switch S3, to avoid 24V battery pack BT1 discharge.SW is ignition switch, and position 0 is position of rest, and position 1 is the operation position, and position 2 is start bits.When SW places 2, contact S1 and S2 all connect, the coil of relay K J1 and KJ2 gets electronic work, the normally opened contact closure of KJ1 and KJ2, the 220V alternating current is added on the 220V AC motor M1 by the contact of KJ1 and KJ2, and M1 starts, and drives 24V Dyn. G1 running, the direct current that sends is given 24V battery pack BT1 charging by current-limiting resistance R, and to other unit power supply of actual training device; The voltage that sends when the 24V Dyn. just often exchanges from of 24V Dyn. inside and to take out voltage through commutation diode on phase line and the neutral line and be added to DC1, and the coil that generating detects relay K J3 gets electronic work, the normally opened contact closure of KJ3; When SW places 1, only contact S1 connects, relay K J1 coil gets electronic work, and the normally opened contact closure of KJ1 is because after starting successfully, the normally opened contact closure of KJ3, therefore, the 220V alternating current is added on the 220V AC motor M1 by the contact of KJ1, KJ3, and generator G1 is kept on the go, the direct current that sends is given 24V battery pack BT1 charging by current-limiting resistance R, and to other unit power supply of actual training device.If generator G1 breaks down in when operation, no-voltage output, KJ3 coil losing electricity and discharging then, the normally opened contact of KJ3 disconnects, 220V AC motor M1 dead electricity and stopping.When SW placed 0, contact S1 and S2 all disconnected, KJ1 coil no-voltage, and the normally opened contact of KJ1 can not be closed, thereby 220V AC motor M1 is in halted state.
