Description
Affiliated technical field
The utility model relates to a kind of locomotive car wheel state robotization pick-up unit, relates in particular to the automatic online device for dynamically detecting of a kind of rail vehicles wheel tread flat and wheel out of round degree.
Background technology
Wheel is to being the critical piece of rolling stock traveling portion, and its state of the art quality directly relates to the riding quality of vehicle, influences train operating safety.At present, owing to many reasons, fault is more to cause the wheel of vehicle flat sliding, peel off etc., makes wheel out of round, and abrasion is not an arc surface but plane or almost plane form " flat wheel ", then influences train operating safety.And because uneven wearing and tearing are that same circumference radius everywhere is inconsistent with making wheel out of round, vehicle operating is not steady, influences the riding quality of vehicle.Therefore, need the scratch and the out-of-roundness of rolling stock be detected, so that the maintenance of vehicle.Existing about the online detection of dynamic of rolling stock wheel to flat sliding, the major technique that adopts has both at home and abroad: 1) electrical signal detection method: when train is run at high speed, wheel will break away from rail level when travelling to the scratch position, and one section duration of passage is arranged; The length of duration of passage is relevant with abrasive size; Measure the wheel duration of passage by electric signal, after simple the conversion, can draw the degree of wheel flat again.But it can't measure the wheel flat of no airborne under the low speed; Difficulty is installed, the short rails of several insulation must be set, and can have a strong impact on the driving order when installing; The life-span of short insulation rail, very unfavorable to line security, this was unallowed on the worker is engaged in rule far below gapless rail.2) sound detection method: roughly judge the size and the position of flat wheel by judging the scratch and the collision sound of rail.This kind mode is installed simply, can be used as the subsidiary scheme.Its shortcoming is can't overcome adjacent wheel to disturb, and the wheel that can only judge flat wheel place is right, and measuring accuracy is not high.3) acceleration detection method: according to the vibration principle, adopt acceleration transducer and wheel load sensor to wait and detect the vibration information that impact produced of flat wheel, and then discern, forecast with spectrum analysis method to rail.But affected by environment bigger, need to consider the factors such as position of the impact of the different speed of a motor vehicle, car weight, car body situation, sleeper railway roadbed rigidity and generation, and need regularly sensor to be demarcated that data processing is difficulty with respect to sensor.4) contact measuring method: form with measuring unit and signal processing unit that relative displacement transducer is formed by two covers or the above parallel-crank mechanism of two covers.It is a benchmark with the wheel rim outer, measures the flat sliding of wheel with respect to the height change on wheel rim summit by measuring wheel tread.Measurement result is more accurate under train slow running condition, and data processing is easy.Its problem is: when the train wheel steel contacted with the flat board of parallel-crank mechanism, because the parallel-crank mechanism undamped, wheel brought bigger impact and vibration for this mechanism, cause dull and stereotyped instantaneous disengaging wheel rim, lose measuring basis, cause omission or mistake to survey the accuracy that influence is measured.And the mode that adopts direct measuring vertical displacement causes Displacement Measurement bigger, is about 15mm, requires the good seismic performance of sensor simultaneously, and is equipped with big displacement quantity and the good high accuracy displacement sensor of anti-seismic performance, costs an arm and a leg, the cost height.
Also there is common problem in above metering system: when wheel was walked, because gapped between wheel rim and the rail side, wheel existed the transversal displacement amount in orbit, also is that wheel can produce teeter; And wheel tread laterally has certain degree of tilt, and as shown in Figure 4, promptly the wheel tread curve is made up of several sections circular arcs.Therefore, when wheel produces teeter, press-fiting about on the same axletree two wheels will contact with rail level and roll with different rolling diameters, causes the rolling circumference radius of wheel tread on rail to change.Even in not scratch, wheel also is under the situation of standard circular, also there is the height change with respect to the wheel rim summit in wheel tread, and obviously only measuring vehicle is taken turns right vertical deviation as out-of-roundness and abrasive measurement result, certainly leads to bigger measuring error.The physical strength of existing measurement mechanism is not enough in addition, also can bring measuring error.
