In the embodiment of, low cost succinct at another, as the connection mode of Fig. 1, multiple road wheels 5 on same track 6 are connected with same frequency converter 23, then in the present embodiment, each road wheel 5 on same track 6 respectively installs a reductor 21, each reductor 21 respectively connects a motor 22, and multiple motors 22 of same track 6 are all connected to a frequency converter 23.
Further, road wheel correcting controller provided by the utility model also comprises telltale 7, controller 3 is also connected with telltale 7, telltale 7 is for the relative position of the wheel rim and track 6 surface that show each road wheel 5, telltale 7 also being gnawed rail for showing, critically being gnawed that rail, walking are normal, the status information such as distance, the two groups of deviation rectification speed in left and right of the wheel rim distance track left and right side, both sides of road wheel, and correction adjustment controling parameters value during display correction.
Below for the walking arrangement of 4 road wheels, road wheel correcting controller provided by the utility model is illustrated, but is not used in restriction of the present utility model:
At the wheel rim of four road wheels 5, a relative position detecting device 1 is respectively installed, the installation site of the relative position detecting device 1 of each installation is kept to be positioned in the geometric centre of road wheel 5, the line of centers of one group of metal inductive switch after installation overlaps with the wheel rim line of centers of road wheel 5, the line of centers of one group of metal inductive switch after installation also with the dead in line of track 6, one group of metal inductive switch is made up of detection head k1, k2, k3, k4, k5, k6, k7, k8, k9 arranged together.In normal walking, detection head k4, k5, k6 overlap with orbital plane; When road wheel 5 is partial to the left side, detection head k6, k7, k8 arrive in orbital plane; When road wheel 5 is partial to the right, detection head k2, k3, k4 arrive orbital plane.In addition, four relative position detecting devices 1 are all connected with controller 3.
If desired more precisely detect the degree that wanders off of each road wheel 5, one group of metal inductive switch is increased to 15 detection heads from 9 detection heads, even more; The accuracy of detection of each detection head is even higher to 3mm.Each installation reductor 21 on four road wheels 5, each reductor 21 respectively connects a motor 22, and two motors 22 on front track 6 are connected on same reductor 21, and two motors 22 on rear track 6 are connected on same reductor 21.380V source of AC all received by two reductors 21, and the signal input part of two frequency converters 23 is all connected to the signal output part of controller 3, then controller 3 controls the output frequency of two reductors 21.The signal input part of controller 3 is also connected with the signal output part of operator's station 4, thus operator's station 4 exports corrective control signal to controller 3.
Based on road wheel 5 correcting controller of above-mentioned citing, when detecting that four road wheels 5 are partial to the left side of direction of travel, i.e. detection head k6, k7, k8 reaches in orbital plane, controller 3 sends the first correction instruction, the speed of travel of the road wheel 5 on the left side is accelerated, the head of walking arrangement is turned to the right fine motion, the relative position of continuous detect lines travelling wheel 5 simultaneously, when the front end of direction of travel is just being walked or more to the right, the detection head k2 of the left front end of direction of travel, k3, when k4 reaches in orbital plane, controller 3 sends the second correction instruction, reduce the speed of travel of left line travelling wheel 5, make the right road wheel 5 speed accelerate and slightly faster than the road wheel 5 on the left side, the afterbody of walking arrangement is moved to the right, just walk, thus make walking arrangement entirety with track 6 center shaft to parallel, reach the movement slightly to the right of walking arrangement entirety, walk positive object.
Constantly repeat above correction process, " " walking of type, until four road wheels 5 are all in the geometric center lines of track 6, namely detection head k4, k5, k6's S of detecting device overlap with the orbital plane of track 6 to make walking arrangement carry out being similar to.When road wheel 5 occurring and being partial to the right, contrary with above adjustment direction, four road wheels 5 finally can be made equally to be all in the geometric center lines of track 6.
By above-mentioned when detect wander off signal time, regulating module 2 controls moving with different speed respectively of both sides road wheel 5 on track 6, realizes correction.
The utility model implements the technical scheme provided, and at least has following technique effect or advantage:
By being installed on relative position detection components on road wheel and regulating module, under the control of the controller, whether relative position detection components detect lines travelling wheel wanders off, when detecting that road wheel wanders off, regulating module adjustment road wheel relative position in orbit, road wheel is made to be on track centerline, rail gnawed by the wheel rim and the track that eliminate road wheel, and then the wheel loss that " gnawing rail " phenomenon can be avoided to cause and track loss, thus improve the service life of road wheel and track, and then wheel rim also can be avoided to gnaw thin rear bevelling, lose guide function and the generation of the great industrial accident plunged off the tracks, ensure that long-term safety is produced.
