Accompanying drawing explanation
The present invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is the main circuit structure figure of trolley control circuit of the present invention.
Fig. 2 is the control circuit structure chart of trolley control circuit of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect,
Below in conjunction with being specifically illustrating, the present invention is expanded on further.
Shown in Fig. 1, Fig. 2, a kind of control circuit for concrete-liner chassis, including main circuit and control
Circuit, main circuit is constituted by with lower component: three-phase power line A1, B1, C1 pass through knife-like switch QF and power line
A2, B2, C2 are connected, and power line A2, B2, C2 are by catalyst KM1 or catalyst KM2 and hot relay
Device FR1 is connected, and catalyst KM1 and catalyst KM2 is connected in parallel, thermorelay FR1 and walking motor
M1 is connected, and power line A2, B2, C2 are connected with thermorelay FR2 also by catalyst KM3, hot relay
Device FR2 is connected with oil pump motor M2；Control circuit includes the first branch road and the second branch road, the first branch road with
Second branch circuit parallel connection connects, and the first branch road is thermorelay FR1 normally-closed contact and start button SB1, catalyst
KM2 normally-closed contact, catalyst KM1 coils connected in series and thermorelay FR1 normally-closed contact and start button SB2,
Catalyst KM1 normally-closed contact, catalyst KM2 coils connected in series, the second branch road is that thermorelay FR2 is normally closed to be touched
Point and stop button SB3, catalyst KM3 normally opened contact, catalyst KM3 coils connected in series and thermorelay FR2
Normally-closed contact and stop button SB3, start button SB4, catalyst KM3 coils connected in series.First branch road and
Serial fuse FU on two branch road buses.Parallel connection power supply display lamp HR1 on first branch road and the second branch road.First
Parallel contactor KM1 normally opened contact and display lamp HR2 branch road is gone back on branch road and the second branch road.First branch road and
Parallel contactor KM2 normally opened contact and display lamp HR3 branch road is gone back on second branch road.On catalyst KM3 coil
Display lamp HR4 in parallel.
During specific works, in main circuit, manual closing knife-like switch QF, three-phase power line A1, B1, C1 and electricity
Source line A2, B2, C2 connect, and catalyst KM1 controls walking motor M1 and rotates forward, and catalyst KM2 controls
