At present, wheel can be divided into double wheel flange wheels, single wheel flange wheel and without three kinds of wheel flange wheel by wheel rim form, by tread
Shape can be divided into cylinder, cone and cydariform wheel.For different wheels, its measuring method is also not quite similar, and at present
Measuring method need various measurers to use cooperatively.According to state quality inspection pot [2002] 296《Hoisting machinery supervision and inspection code》
The regulation of the 5.7th, the survey tool used wheel wear is mainly slide calliper rule, in the detection foundation of other correlations also not
Clearly state.Concrete main test event method of testing is as follows：
1st, for the measurement of thickness of wheel rim：
Common method is that the thickness of wheel rim is measured with the slide measure shown in Fig. 5.This measuring method behaviour
Make relatively simple, but have the factor for being unfavorable for the degree of accuracy：According to JB/T6392-2008《Crane wheel》In content, lifting
There is the inclined-plane (as shown in Figure 1) that an angle is a in locomotive wheel inner side wheel rim.When being measured with slide measure, due to
The depth of measurement can not accurately be determined, the flange thickness that cannot accurately know measured position is caused.With JB/T6392-2008
《Crane wheel》In the maximum standard wheel enumerated, its flange height is 30mm, and a angles are 10 °, position as shown in Figure 11
It is about 5.29mm with the difference of position 2, its error at interval of 1mm that fathoms also has reached 0.18mm, needed for being unsatisfactory for detection
The required precision wanted.
2nd, for the measurement of wheel tread diameter：
Conventional method is with slide measure or miking tread diameter.But this method can only be less for diameter
Wheel, on the one hand want that selected range is larger, the slide measure that measuring jaw is longer or micrometer, generally require many people coordinate, it is multiple
Measurement；On the other hand the wheel end carriage that has crane above it cover tread, have track to cover its tread (such as below
Shown in Fig. 2), cause slide measure or micrometer to wheel cannot measure.
For the wheel being relatively large in diameter, Jiangsu Te Jian institutes have developed and be measured with π chis.By π chis around crane during measurement
On the excircle of wheel, both hands apply certain pulling force, using cursor principle reading, obtain final product the mean diameter value of measured piece.Nothing
By great diameter is measured, using measurement auxiliary (magnetic support) single measurement is capable of achieving.But for wheel, due to its position
On track (as shown in Figure 2), and be also with the wheel tread of rail contact often wear extent maximum where, the position it is cylindrical
Zhou Wufa is wound with π chis, thus π chis to part wheel cannot also realize convenient measurement.
3rd, for the diastrophic measurement of thickness of wheel rim：
Conventional method is to coordinate clearance gauge to measure (as shown in Figure 3) with horizon rule.The method is in wheel with horizon rule
The outside of edge, side is adjacent to wheel rim, and side is padded with clearance gauge, and when horizon rule bubble is located at center, the thickness of clearance gauge is
Deflection, then compare with the thickness of wheel rim, determine whether exceeded.The shortcoming of the method mainly has following three points：1) 2 kinds of amounts are needed
Tool is used cooperatively, not easy to operate；2) wheel rim root cannot be accurately judged in which position, easily cause datum mark that clearance gauge puts not
Accurately, data are in turn resulted in and produces error；3) to keep horizon rule contact with wheel section good, generally be pasted with hand reinforcing
Tightly, then padding chi, firmly different measuring result is just different, have impact on accuracy.
4th, for the vertical divergence of wheel：
Using frame level and clearance gauge, (as shown in Figure 4) similar with the diastrophic measuring method of thickness of wheel rim.
But the shortcoming of the method is also similar with the diastrophic measuring method shortcoming 1,3 of thickness of wheel rim.
And for the measurement of the parts such as pulley, steel wire rope, brake, its current measuring method is similar with wheel with drawback,
Do not carry out repeating elaboration.
In sum, the measurer of special efficient detection crane parts is currently there is no both at home and abroad.
