Description
Technical field
The utility model relates to a kind of detection correcting controller that beam crane is gnawed of eliminating, and belongs to the control system technical field of beam crane.
Background technology
Beam crane is being born the linking task of each link of smelter, there is the phenomenon of gnawing in various degree in the hoisting crane of existing beam type weight-lifting equipment more than 75%, not only cause a large amount of economic losses and waste of human resource, and the seriousness of safety problem exposes to the open air undoubtedly especially, is badly in need of having the crane correction control method of application value.
Summary of the invention
The purpose of this utility model is to solve the problems of the technologies described above, and designs a kind of detection correcting controller that beam crane is gnawed of eliminating, and eliminates the problem that beam crane is gnawed.
The technical solution of the utility model: of the present utility modelly a kind ofly eliminate the detection correcting controller that beam crane gnaws and comprise the variable-frequency motor governor, its variable-frequency motor governor is divided into left machine governor and right machine governor, at road wheel before and after road wheel and the right side before and after the left side of beam crane the left front position transduser that detects distance between road wheel and the track is set, left back position transduser, right front position transduser and right back position transduser, left front position transduser, left back position transduser, right front position transduser be connected position transduser and be connected with central process unit, the output of central process unit and left machine governor be connected machine governor and be connected, the status signal of crane operation instruction is connected to central process unit.
Described left front position transduser, left back position transduser, right front position transduser and right back position transduser are mounted in the induction limit switch at road wheel outer rim place.
The sensitive surface of described induction limit switch is parallel with the wheel inner edge, and the distance of induction point and track is 3～5mm.
The beneficial effects of the utility model: the utility model has solved the following problem of gnawing:
● because the alignment error of two groups of speed governing systems causes poor the gnawing of causing of the speed of a motor vehicle.
● disperse because of the synchronous speed of four motors of cart and to cause poor the gnawing of causing of the speed of a motor vehicle.
● because the error of cart wheel diameter causes poor the gnawing of causing of the speed of a motor vehicle.
● because the height of foundation error of bar track causes asymmetric the gnawing of causing of body gravity.
● because of little truck position with hang thing and cause asymmetric the gnawing of causing of body gravity.
● because of gnawing that the adjustment of cart vehicle wheel component and reductor causes that resistance difference causes.
● because of gnawing that the adjustment of the brake clearance of large vehicle brake causes that resistance difference causes.
● because causing the friction between track and the wheel, certain reason changes gnawing of causing.
● because of gnawing that the car body physical dimension changes and causes.
● because of set of wheels and gnawing that the relative error (level, vertical) of car body causes.
● because of gauge the gnawing that (crooked, the Eight characters) cause that change.
Use the utility model can greatly prolong service life of road wheel, reduce the replacing frequency of track, for the safe operation of equipment provides guarantee.

Fig. 2 is installation site figure of the present utility model.
The specific embodiment
Fig. 2 is installation site figure of the present utility model: the utility model is 4 induction limit switches that distance between detection road wheel outer rim and the track is set in the outer rim of road wheel before and after road wheel and the right side before and after the left side of beam crane.
Fig. 1 is functional block diagram of the present utility model: the utility model provides a kind of detection correcting controller that beam crane is gnawed of eliminating, and hoisting crane traction drive motor is variable-frequency motor, is controlled by the variable-frequency motor governor.
Its variable-frequency motor governor is divided into left machine governor and right machine governor, at road wheel before and after road wheel and the right side before and after the left side of beam crane the left front position transduser that detects distance between road wheel and the track is set, left back position transduser, right front position transduser and right back position transduser, left front position transduser, left back position transduser, right front position transduser be connected position transduser and be connected with central process unit, the output of central process unit and left machine governor be connected machine governor and be connected, the status signal of crane operation instruction is connected to central process unit.
Described left front position transduser, left back position transduser, right front position transduser and right back position transduser are mounted in the induction limit switch at road wheel outer rim place.
Described induction limit switch is installed on the live axle bolster by mounting bracket, and its sensitive surface is parallel with the wheel inner edge, and the distance of induction point and track is 3～5mm.The distance of namely responding to the limit and track is sent during less than 3mm and is gnawed signal, and the distance of the induction limit and track is gnawed blackout during greater than 5mm.
At an axletree coder is installed, central process unit records the crane run location, gnaws the position.
The utility model is on the basis that does not change the electric and mechanical characteristics of former cart, a wheel sideslip respectively is installed at four jiaos of road wheel outer rims of car body place is detected the induction limit switch, car body sideslip status data is sent in the central process unit, crane walking states (working direction) signal feedback of operating order is to central process unit simultaneously, central process unit is according to the crane direction of travel, carry out sending the instruction of two groups of cargo motor rotating speeds of adjustment to left machine governor and right machine governor after the comprehensive treatment according to basic data and the car body sideslip status data of correction model to crane, the speed that changes two groups of cargo motors is poor, eliminates the purpose that wheel is gnawed thereby reach.
Judge for the model of guaranteeing to rectify a deviation car body sideslip data accuracy, correction process speed of response and avoid making the car body vibration because of the overshoot of correction process, establish sideslip discriminant function and correction intensity function in the correction model.During less than 5mm and greater than the judgement time, device then sends speed-regulating signal such as the distance that detects crane wheel rim and track when device, for avoiding adjusting excessive device with the intensity of adjustment time error correct.
For guaranteeing that avoiding being subjected to ambient interference to produce mistake gnaws signal, device is provided with to be gnawed the time of judgement, for correction overshoot device also is provided with the setting of correction intensity.For improving the integrated management to gnawing, the particular location that device can provide crane to gnaw with curve mode provides quantitative basis for adjusting wheel or track.
Be the error signal of avoiding gnawing, in the PLC program, set up 1 second time filtering function, namely gnaw signal and just work greater than 1 second signal.
Excessive for avoiding rectifying a deviation, the difference on the frequency of two groups of frequency converters progressively increases take 0.1H as basic point.
In like manner, also can adopt other detecting sensor part.
