Between the first pin a of left end head station C and ground, order is in series with the normally opened contact J1-1 of the first relay J 1, the first normally closed contact ZJ2-1 of the relay ZJ2 that sneaks away, close and slip relay ZJ1, is parallel with to close in addition slips the first normally opened contact ZJ1-1 of relay ZJ1 with the normally opened contact J1-1 of the first relay J 1;
Between the second pin b of left end head station C and ground order be in series with the 3rd relay J 3 normally opened contact J3-1, relay ZJ2 sneaks away;
Between the first pin c of right-hand member head station D and ground, order is in series with the normally opened contact J2-1 of the second relay J 2, the second normally closed contact ZJ2-2 of the relay ZJ2 that sneaks away, close and slip relay ZJ1, is parallel with to close in addition slips the second normally opened contact ZJ1-2 of relay ZJ1 with the normally opened contact J2-1 of the second relay J 2;
Between the second pin d of right-hand member head station D and ground order be in series with the 4th relay J 4 normally opened contact J4-1, relay ZJ2 sneaks away.
On left telepilot A, comprise and sneak away switch and close the pass of shying away, and two switches are reset switch; On right telepilot B, also comprise and sneak away switch and close the pass of shying away, and two switches are reset switch; Left telepilot A is by the first relay J 1 in master controller M control left end head station C and the power on/off of the 3rd relay J 3; Right telepilot B is by the second relay J 2 in master controller M control right-hand member head station D and the power on/off of the 4th relay J 4; The relay ZJ2 and closing of sneaking away slips relay ZJ1 and is installed in coalcutter fuselage; The first relay J 1, the second relay J 2, the 3rd relay J 3, the 4th relay J 4 are slipped the power on/off of relay ZJ1 for controlling the relay ZJ2 and closing of sneaking away, thereby realize, the switching of coalcutter is slipped to remote control control.
What described master controller M adopted is that model is the PLC of FX2N, described the first relay J 1, the second relay J 2, the 3rd relay J 3, the 4th relay J 4, the relay ZJ2 that sneaks away, close slip relay ZJ1, close that to slip the model of button Is3 be JTX-2C.
In practical application, because need two coal mining drivers during coalcutter work, the length of coalcutter own is 15 meters of left and right, in order to work conveniently, hereby at left end head station C and right-hand member head station D the inside, all add relay, facilitate any one coal mining driver operation, strengthened security and shortened the crash time simultaneously.During working face extraction operation, coal mining driver stands in hydraulic support inner side observation coalcutter operation conditions and is prepared to stop at any time, in operation process, running into large spoil enters transporter or other emergency condition without fragmentation and need to take to stop while processing, coal mining driver only need by closing of bottom left telepilot A shy away close or right telepilot B close the pass of shying away, complete to close and slip shut-down operation.
While closing when shying away by closing of bottom left telepilot A, left telepilot A sends to close and slips signal, master controller M receives to close and slips signal by analyzing rear first relay J 1 of connecting of judgement, after the first relay J 1 energising, thereby the normally opened contact J1-1 of the first relay J 1 is closed to be connected to close and slips relay ZJ1, close and slip relay ZJ1 energising, close and slip the normally closed contact ZJ1-3 of relay ZJ1 and open, transporter controlled stop, in addition, thus close slip the first normally opened contact ZJ1-1 of relay ZJ1 closed form to close slip the self-insurance path of relay ZJ1;
While closing when shying away by closing of bottom right telepilot B, right telepilot B sends to close and slips signal, master controller M receives to close and slips signal by analyzing rear second relay J 2 of connecting of judgement, after the second relay J 2 energisings, thereby the normally opened contact J2-1 of the second relay J 2 is closed to be connected to close and slips relay ZJ1, close and slip relay ZJ1 energising, close and slip the normally closed contact ZJ1-3 of relay ZJ1 and open, transporter controlled stop, in addition, thus close slip the second normally opened contact ZJ1-2 of relay ZJ1 closed form to close slip the self-insurance path of relay ZJ1.
Complete and close the work of sneaking away during work hours, in the time of need to opening transporter, by the switch of sneaking away on left telepilot A or right telepilot B.
When by sneaking away during switch on bottom left telepilot A, left telepilot A sends the signal of sneaking away, master controller M connects the 3rd relay J 3 after receiving the signal post analysis judgement of sneaking away, the 3rd relay J 3 energisings, the normally opened contact J3-1 of the 3rd relay J 3 is closed, thereby connects the relay ZJ2 that sneaks away, the relay ZJ2 that sneaks away energising, thereby the first normally closed contact ZJ2-1 of the relay ZJ2 that sneaks away and the second normally closed contact ZJ2-2 open, close and slip relay ZJ1 power-off, the controlled unlatching of transporter;
When by sneaking away during switch on bottom right telepilot B, right telepilot B sends the signal of sneaking away, master controller M connects the 4th relay J 4 after receiving the signal post analysis judgement of sneaking away, the 4th relay J 4 energisings, the normally opened contact J4-1 of the 4th relay J 4 is closed, thereby connects the relay ZJ2 that sneaks away, the relay ZJ2 that sneaks away energising, thereby the first normally closed contact ZJ2-1 of the relay ZJ2 that sneaks away and the second normally closed contact ZJ2-2 open, close and slip relay ZJ1 power-off, the controlled unlatching of transporter.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
