2, the action of tower machine trainstop.
3, horizontal arm type tower machine: the deceleration of the forward and backward operation of travelling jack and parking.
4, luffing jib formula tower machine: big arm is bowed, the parking of elevation angle operation is spacing.
Networking operation control process of the present utility model:
Be that example elaborates to networking operation control process with 3 typical actual conditions below:
1., contour two tower machines revolution operation control
When two tower mounting distances during less than two big arm lengths sums, two big revolution of arms near the time must in time stop and brake in case of necessity, otherwise big arm collision case may take place.
As shown in Figure 6, the static or right-hand rotation of A right-hand rotation B
S 1Minimum perpendicular distance between-two big arms is the dynamic change value.
S 2The safe early warning distance of-keyboard input.
S 3The safety of-keyboard input (outage of stopping) distance.
S 4The stopping distance (minimum safe distance) of-keyboard input.
System program is decision height and the establishment of locating distance condition at first, continuously calculates S again 1Value and with itself and S 2, S 3, S 4Value compares, and produces following several controls respectively:
A.S 2〉=S 1〉=S 3The time, system program will send to A tower PLC.
Left-hand rotation early warning order 01.A tower PLC program receives 01 order and carries out immediately: P 2Output point 1.0 and P 3The point.4 are interrupted output DC24V+ voltage, read-out is turned right limit lamp L 1Be interrupted glittering; The R interruption is rung.
B.S 1≤ S 3The time, system program will send left-hand rotation limiting command 01 to A tower PLC.A tower PLC program receives 02 order and carries out immediately: P 2Output point 0.7 and 1.0 and P 3The point.4 reach.5 connect output DC24V+ voltage, relay J 1Meet electronic break contact (turn right and stop) and the read-out right-hand rotation restriction lamp L of doing 1Chang Liang; R Chang Ming.
C. big arm is because inertia will continue to slide deceleration.Work as S 1≤ S 4The time, system program will send left-hand rotation limiting command 00 to A tower PLC.Execution result is: when previous state (being the b state here) keeps, and P 2Output point ground 0.2 output DC24V+ voltage, relay J 3Connect and electronicly carry out rotary braking as break contact.
2., not contour intersection two tower machines revolution operation control
Collision will occur between high tower suspension hook cable wire and the big arm of low tower, guarantee that promptly the high tower dolly do not cross over the low big arm of tower.See Fig. 4: it is low to establish the high B of A, and A changes the static or right-hand rotation of B
S 1Minor increment between big arm of-B and A dolly is the dynamic change value.
S 2The safe early warning distance of-keyboard input.
S 3The safety of-keyboard input (outage of stopping) distance.
S 4The stopping distance (minimum safe distance) of-keyboard input.
L-B tower entity is the dynamic change value to the minor increment of A tower center of gyration.
The actual dolly range value of RA-A tower.
System program at first decision height and locating distance condition is set up not, then relatively judges RA and L value as setting up, and continuously calculates S when RA 〉=L again 1Value, and with itself and S 2, S 3, S 4Value compares, the same a.b.c. item 1. of subsequent control content.
As A, when the B tower turns round relatively, system program will be to S 1, S 2, S 3, S 4Value is done * 2 and is handled.
The control of trolley travelling when 3., the big arm of Low Towers intersects
Controlled target is that assurance high tower dolly (suspension hook) is not crossed over the low tower sky.
As shown in Figure 5, it is low to establish the high B of A, and the A dolly outwards moves
I 1-high tower dolly to the point of crossing distance, is dynamic value along service direction.
I 2Dolly deceleration (broken height speed) early warning distance that-keyboard is gone into.
I 3The dolly safe stopping distance of-keyboard input.
System program at first decision height and locating distance condition is set up not and whether is in crossing condition, and as being in crossing condition, system program will continuously calculate I 1Value, and with itself and I 2, I 3Value compares, and produces following several controls respectively;
A.I 1＞I 2The time, system program does not have any instruction and sends.
B.I 1≤ I 2System program will send dolly to A tower PLC and outwards move deceleration (changeing low speed at a high speed) order 21.A tower PLC program receives 21 orders and carries out immediately: P 2Output point 0.4 output DC24V+ voltage makes J 5The relay power action disconnects at a high speed outwards operation circuit, P simultaneously 3The point.0 reaches.5 are interrupted output DC24V+ voltage, make read-out outwards move restriction lamp L 3Be interrupted glittering; The R interruption is rung.
C.I 1During=I2, system program will send dolly to A tower PLC and outwards move restriction (parking) order 22.A tower PLC program receives 22 orders and carries out immediately: P 2Go out a little 0.4 and 0.3 and P 3The point.0 reaches.5 continue output DC24V+ voltage, relay J simultaneously 5Keep connecing electricity condition and J 4Connect electronic work, the disconnection dolly outwards moves circuit (parking) and read-out outwards moves restriction lamp L 3Lamp Chang Liang; R Chang Ming.
3., the main effect of reset switch
A. in the tower machine operational process, every collision once, system program just covers renewal with stock's initial setup data to system's real data, guarantees that all the time actual position is consistent with system data.
B. because of some shutdown of reason collision avoidance system or off-grid; And tower machine withdraw from use not, when opening collision avoidance system and normal networking work once more, big arm true bearing of tower machine and dolly position are not inconsistent the data in complete and the system program (data at that time of storing automatically during outage), and the initial collision of reset switch can solve.
