The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
Fig. 1 is the structure diagram of single tower machine.Fig. 2 is the connection mode sketch that a plurality of tower machines are formed network.As shown in the figure; during the work of the utility model normal cluster; the continual reception of the data collecting card of each unit comes to trolley travelling and rotating data; the software of native system goes out real-time tower seat in the plane by data computation and puts and the dolly amplitude; and these data are issued other tower machines of networking in the native system by wireless telecommunications system; meanwhile receive the data that other tower machines send; whether may occur disturbing by above data computation and bump mutually or near the protection zone of forbidding that fishhook (or big arm) is crossed over; as the street; the campus; railway; the expressway; during electrical network or the like; when perhaps fishhook is beyond the boundary; system sends instruction; earlier tower machine operation person is sent the acousto-optic early warning; until the electrical controller action of control tower machine, the continuation of this operation of automatic spacing, and reciprocal operation is not affected.
The utility model comprises following content to the Based Intelligent Control of this tower machine operation: 1, the left and right rotating parking of tower machine is spacing; 2, the action of tower machine trainstop; 3, horizontal arm type tower machine: dolly is to the deceleration and the parking of forward and backward operation; 4, luffing jib formula tower machine: big arm is bowed, the parking of elevation angle operation is spacing.
Be that example elaborates to the networking operation control process with 3 typical actual conditions below:
1. contour two tower machines revolution operation control
When two 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 5, the static or right-hand rotation of A right-hand rotation B; Minimum perpendicular distance between D1-two big arms is the dynamic change value; The safe early warning distance of D2-system input; The safety of D3-system input (outage of stopping) distance; The stopping distance (minimum safe distance) of D4-system input.
Whether system program at first decision height and mounting distance condition is set up, and continuously calculates the D1 value again and itself and D2, D3, D4 value are compared, and produces following several controls respectively:
When a, D2 〉=D1 〉=D3, right-hand rotation early warning operation is made by the system on the A tower machine: the right-hand rotation arrow that shows on the telltale is by green flavescence, and rings with the interruption of R.
When b, D1≤D3, the right-hand rotation alarm operation is made by the system on the A tower machine: the right-hand rotation arrow that shows on the telltale is red by xanthochromia, and with R continue ring, relay J 1 is opened by normally closed often becoming.
C, big arm are because inertia will continue to slide deceleration.As D1≤D4, the right-hand rotation brake operating is made by the system on the A tower machine: the right-hand rotation that shows on telltale indication arrow is for red, and with R continue ring, relay J 2 actions, the contact is opened by normally closed often becoming.
2. not contour two tower machines revolution operation control
Collision will occur between high tower fishhook 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. 5, it is low to establish the high B of A, and A changes the static or right-hand rotation of B; Minor increment between big arm of D1-B and A dolly is the dynamic change value; The safe early warning distance of D2-system input; The safety of D3-system input (outage of stopping) distance; The stopping distance (minimum safe distance) of D4-system input; L-B tower entity is the dynamic change value to the minor increment of A tower center of gyration; The actual dolly amplitude of RA-A tower.
Whether system program at first decision height and mounting distance condition is set up, and then relatively judges RA and L value as setting up, and continuously calculates the D1 value again and itself and D2, D3, D4 value is compared same a, b, the c item 1. of its control content when RA 〉=L.
Trolley travelling control 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 6, it is low to establish the high B of A, and the A dolly outwards moves; The distance of L1-high tower dolly along service direction to point of crossing is the dynamic change value; Dolly deceleration (broken height speed) early warning distance of L2-system input; The dolly safe stopping distance of L3-system input.
Whether system program at first decision height and mounting distance condition is set up, and whether is in crossing condition, if be in crossing condition, system program continuously calculates L1 value and its and L2, L3 value are compared, respectively several controls below the generation:
System does not have any control operation when a, L1＞L2.
When b, L1≤L2, the system on the A tower machine makes dolly and outwards moves deceleration-operation: the outside operation indication arrow that shows on the telltale is by green flavescence, and rings with the interruption of R, relay J 6 actions, and the contact is opened by normally closed often becoming.
When C, L1=L2, the system on the A tower machine makes dolly and outwards moves restriction operation: the outside operation indication arrow that shows on the telltale is red by xanthochromia, and with R continue ring, relay J 5 actions, the contact is opened by normally closed often becoming.
