Detailed description of the invention
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of crane cross track hangs the embodiment of automatic centering system, automatic centering system in this embodiment is arranged on the butt end place of main Car Track 1 detection bodies 3 when comprising use be arranged on when using secondary Car Track 2 butt end place tracking sensor module 4 and for receiving the detection signal sent when tracking sensor module contacts with detection bodies, and send adjusting microinching control signal to adjust the PLC of secondary car tracking position according to received detection signal to secondary car, detection bodies is herein angle bar, tracking sensor module 4 herein comprises left tracking sensor 42 and right tracking sensor 41, wherein, left, right tracking sensor lays respectively at the left and right sides of secondary Car Track 2, left tracking sensor 42 contacts backward PLC with right tracking sensor 41 with detection bodies and sends detection signal, PLC is according to a received left side, the detection signal that right tracking sensor sends sends adjusting microinching control signal to control secondary Car Track 2 adjusting microinching to the drive motor 7 of secondary Car Track, finally realize the automatic centering of main Car Track 1 and secondary Car Track 2.
As shown in Figure 5, corresponding with left tracking sensor in PLC left proximity switch S93 and the right proximity switch S94 corresponding with right tracking sensor is normal open switch.During use, left proximity switch S93 is closed when left tracking sensor proximity test body to be connected, and export gap on-off signal after PLC computing, control relay K01 does interval on-off action, then control contactor K10 action, makes secondary Car Track do adjusting microinching.Be provided with the secondary Car Track of the left tracking sensor corresponding with left proximity switch, during by the main Car Track that is fixed with detection bodies, when main Car Track and secondary Car Track centering, left proximity switch S93 disconnects, and controls secondary Car Track centering and moves stopping.Right proximity switch S94 is identical with the principle of work of left proximity switch S93, during use, right proximity switch S94 is closed when right tracking sensor proximity test body to be connected, PLC computing exports gap on-off signal, control relay K02 does interval on-off action, then control contactor K20, makes secondary Car Track do adjusting microinching.The secondary Car Track of the right tracking sensor corresponding with right proximity switch is housed, and by being installed with the main Car Track of detection bodies, when main Car Track and secondary Car Track centering, right proximity switch S94 disconnects, and controls secondary Car Track centering and moves stopping.
As shown in Figure 2, the automatic centering system that above-described embodiment provides is applied in crane cross track when hanging, when crossing rail centering, usually main Car Track is reached apart from secondary Car Track about 200mm, connect the centering select switch S0 of secondary Car Track 2, left tracking sensor 42 is connected with detection bodies 3, the left proximity switch S93 corresponding with left tracking sensor 42 connects, by PLC signal be converted into intermittency signal come control relay K01 do interval break-make, relay K 01 controls secondary Car Track 2 adjusting microinching, until secondary Car Track 2 and main Car Track 1 centering, as shown in Figure 3, left tracking sensor 42 departs from detection bodies 1, left proximity switch S93 disconnects.If secondary Car Track 2 does not have centering due to inertia, left side tracking stops.Start right rail excessively, as shown in Figure 4, right tracking sensor 41 is connected with detection bodies 1, the right proximity switch S94 corresponding with right tracking sensor 41 connects, by PLC, signal is converted into intermittency signal to carry out control relay K02 and do gap break-make, relay K 02 controls secondary Car Track 2 adjusting microinching tracking to the right, until centering.Then centering indicator lamp brightens, and centering completes.
In the above-described embodiments, for ease of introducing automatic centering system, detection bodies in automatic centering system is arranged on main Car Track, left and right tracking sensor is then arranged on secondary Car Track, in other embodiments, also detection bodies can be arranged on secondary Car Track, then left and right tracking sensor is then arranged on main Car Track, now, the control of PLC inside also needs to do corresponding adjustment, to realize the normal centering of main Car Track and secondary Car Track.
In above-described embodiment, left and right tracking sensor is installed with respectively in the left and right sides of secondary Car Track, in other embodiments, also can left tracking sensor be only set in the left side of secondary Car Track or only right tracking sensor be set on the right side of secondary Car Track, but so can only realize one-sided centering, the automatic adjustment center support system of regulated efficiency not as providing in above-described embodiment.
In above-described embodiment, detection bodies is angle bar, and in other embodiments, detection bodies also can adopt steel plate or other can touch tracking sensor and make the steel material member of tracking sensor output signal.
As shown in Figure 1, the embodiment that a kind of crane cross track hangs, rail bull ladle of crossing in this embodiment draws together the main Car Track 1 and secondary Car Track 2 that mutually dock, be provided with between main Car Track 1 and secondary Car Track 2 and automatic centering system is installed, this automatic centering system is identical with the structure of the automatic centering system shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, do not repeat them here, detection bodies 3 is fixedly mounted on the butt end of main Car Track 1, and tracking sensor module is arranged on the butt end of secondary Car Track 2.Main Car Track 1 is provided with main car drive motor 6, and secondary Car Track 2 is provided with secondary car drive motor 7, and wherein, main car drive motor 6 is all connected with the signal output part of PLC with secondary car drive motor 7.The motor push rod type anchor fitting 5 for both being fixed together after major and minor Car Track centering docking is also provided with between main Car Track 1 and secondary Car Track 2.After main Car Track 1 and the docking of secondary Car Track 2 centering, the rail cucurbit 8 excessively on main Car Track 1 is carried lifting article and moved rail to secondary Car Track 2 from main Car Track 1.
In the above-described embodiments, detection bodies is arranged on main Car Track, left and right tracking sensor is then arranged on secondary Car Track, in other embodiments, also detection bodies can be arranged on secondary Car Track, then left and right tracking sensor be arranged on main Car Track, now, the control of PLC inside also needs to do corresponding adjustment, to realize the normal centering of main Car Track and secondary Car Track.
In the above-described embodiments, for two hoisting cranes that will realize tracking, the hoisting crane being originally loaded with rail cucurbit or the weight that hoists is called main car, will waits for that the hoisting crane of rail was called secondary car.Because secondary car its inertia before realizing rail is less than main car, so above-mentioned two embodiments all realize adjusting the centering of main Car Track and secondary Car Track by controlling secondary Car Track adjusting microinching.Certainly, also can control main Car Track adjusting microinching to realize centering adjustment, but this adjustment mode not only regulated efficiency is low, simultaneously also more dangerous.
