Description
Technical field
The present invention relates to a kind of method of controlling maintenance depressed place smooth running.
Background technology
The maintenance depressed place, as the widespread use in the manufacturing of main equipment and maintenance of a kind of equipment, common have aircraft maintenance depressed place and a steamer maintenance depressed place.With the aircraft maintenance depressed place is example: the aircraft maintenance depressed place is the steel structure equipment that aircraft maintenance storehouse, airport is used for the repair and maintenance aircraft.According to the different model of maintenance aircraft, machine depressed place size is also inequality.According to the different parts of maintenance aircraft, the aircraft maintenance depressed place can be divided into head depressed place, fuselage depressed place, vertical fin depressed place, big wing depressed place etc.Be example now with maintenance Boeing-747 airframe depressed place: about 60 meters of fuselage depressed place total length, high about 25 meters, wide about 3 meters, heavily about 60 tons.Fuselage depressed place need are distinguished easy motion with vertical direction in the horizontal direction, prior art is: horizontal direction adopts two ends two motor gear retarders to be set respectively on roof truss rail road, four motor gear retarder synchro switch controls, vertical direction adopts both ends a motor gear retarder to be set respectively on hanger bracket, two motor gear retarders also adopt synchro switch control, in the normal operation of fuselage depressed place, when needing parallel motion, four running motors that require to make parallel motion on the roof truss rail road are worked simultaneously, speed is the same, make equally, finally make the same moved further in whole fuselage depressed place with four drive wheels of four motor gear retarder bonded assemblys rolling speed in orbit; Similarly, during the normal operation lifting moving of fuselage depressed place, require two motor gear retarders at both ends, fuselage depressed place to work simultaneously, guarantee that platform both ends, depressed place lifting moving speed is the same.But in fact the fuselage depressed place is usually moved asynchronously, and move in the fuselage depressed place asynchronously has a lot of reasons to cause: on the one hand, can not guarantee in the manufacturing that the rotating speed of each motor is definitely the same; On the other hand, the fuselage depressed place is formed by steel construction piece assembly unit weldering knot, make and can not guarantee that the two ends loading of fuselage depressed place is the same, and the original shape in fuselage depressed place just makes existing fuselage depressed place two ends loading that very big difference is arranged, this can make the heavy end of load move slowly, and the light end of loading moves soon; In addition, the level in fuselage depressed place and vertical shifting retarder assembly clearance also can not be the same with the gear wear degree, and the output speed that gap and wearing and tearing are big is slow; When transmission clutch locating dowel pin gets loose, though motor changeing, unpowered transmission, the fuselage depressed place is motionless; Moreover roof truss rail length is about 100 meters, also exist to install and the welding deformation problem, can skid when running into the rail place of the arch camber that makes progress slightly during the motor driven wheel moves, and makes an end that skids at wheel in the fuselage depressed place move slow even motionless; Simultaneously, certain electric elements has fault or motor gear retarder to be out of order, and all can make the asynchronous work in fuselage depressed place.Before the work of fuselage depressed place, it is synchronous to mix up the depressed place, after work a period of time, increases owing to above-mentioned multiple reason makes accumulated error, and asynchronous federation takes place.The asynchronous meeting in fuselage depressed place makes fuselage depressed place steel structure torsional deflection and damage or makes elevating screw seriously crooked, the lost of life.Asynchronous to make two ends, fuselage depressed place move offset distance big more, and the damage of fuselage depressed place is serious more.If untimely inspection and correction, consequence is serious.Now, the method for asynchronous problem is handled on the airport: the one, by people's visual inspection, find tangible asynchronous just correction.At this moment, the asynchronous deviation in fuselage depressed place has reached more than the 300-500 millimeter, and eyesight is poor slightly or careless, can't see to go wrong.The 2nd, the special messenger regularly climbs up the fuselage depressed place and measures relatively with chi.The 3rd, seriously asynchronous in the fuselage depressed place, draw through structure friction and to turn round and send ear-piercing cry, or the fuselage depressed place to be stuck, the excessive sky that causes of motor current is opened tripping operation, just proofreaies and correct processing.Generally the method for handling is, manually select switch is pulled the single action position, only starts the fuselage depressed place and moves a slow end motor, and mobile fuselage depressed place is to synchronous regime.Then, select switch is pulled the interlock position of normal operation, allow two ends motor normal operation together again.The 4th, at concentric on every end motor shaft of fuselage depressed place parallel motion and vertical shifting or on the output shaft of motor gear retarder A/B two-phase orthogonal pulses increment rotary encoder is installed.The number of turns that on behalf of S. A., the number of rotary encoder count pulse turn over by the pulse count of Programming of programmable controller contrast calculating two ends, fuselage depressed place coder, just can calculate whether the rotary shaft rotating speed at two ends, fuselage depressed place is the same.If different, just stop the motor that a fast end is moved in the fuselage depressed place, allow and move a slow end motor operations.When the count pulse number of two ends, fuselage depressed place coder is the same, just allow the two ends motor work together.So constantly relatively calculate the encoder pulse number at two ends, fuselage depressed place, the start-stop of two ends, regulating control fuselage depressed place motor is moved the purpose of syn work to reach the two ends, depressed place, yet under the situation of wheel slip, the method synchronized movement of also having no idea to make.So prior art exists not enough: a kind of method that can avoid the control maintenance depressed place smooth running of maloperation can not be provided.
Summary of the invention
