Description
Technical field
The utility model relates to a kind of device of wheel polygon detecting more particularly to a kind of rail vehicle wheel polygons
Detection device.
Background technique
Wheel is the component connected between train body and track, is positioned on the downside of bogie, mainly there is conduction vertical force
With the effect of guiding, so being essential component.Guarantee the even running of vehicle, first is that guarantee the smooth of track, two
It is to ensure that the smoother of wheel.It is exactly common one of wheel fault that wheel out of round is suitable.Wheel out of round includes local defect, flat
Scar, peel off, fall off, tyre tread protrusion, wheel polygonization and wheel aperiodicity be not smoother etc..
Frequently referred to wheel wave is ground wheel polygon phenomenon, wheel harmonic wave is worn away or the periodically non-sphering of wheel again, common to arrange
Can all occur wheel polygon phenomenon on vehicle and bullet train.Diameter jump amount is more than that the wheel polygon defect of 0.3mm can make vehicle
Vibration aggravation between rail system seriously damages and increases wheel-rail impact and rolling noise to track and vehicle part generation,
Especially in bullet train operation, wheel polygon constitutes potential threat to vehicle safety operation.When wheel generation is polygon
When shape situation is more serious, it is necessary to carry out rotation and repair or grinding process, wheel pair must be replaced when situation is serious.Wheel it is polygon
The emergence and development of shape phenomenon not only influence the service life of vehicle and track structure, but also serious damage may result in
The generation of great derailment accident.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art and meet accurate, practical, easy-to-use detection, the utility model provides one
The device of kind wheel polygon detecting, the device are mounted on the percentage of secondary bar by clamping device using single-chip microcontroller as control core
Table is contacted with tyre tread zero distance, and by wheel rolling, dial indicator measuring head keeps the contact of a circle with wheel tread, works as wheel pedal
When there is defect in face, it may appear that a diameter jump amount can directly be captured by dial gauge and be sent to sensor, sensor is then
Data are exported to data processor, when data exceed prescribed limit, data processor issues the simultaneously sounding that instructs and send out a warning
Alarm.The adjustable magnet of detection device can adjust magnetism by magnet knob, so that it is safe and reliable when carrying out adsorption operations, no
Easy clamp hand.The adjustable right angle conversion of detection device, gauge stand press from both sides and can revolve dial indicator holder and allow the device to for different shaped
Number wheel adjust, device is easy for installation, easy to operate, accuracy is high.
The technical scheme adopted by the invention is that: utilize the wheel tread both sides junction in the case of wheel generates polygon
Necessarily lead to protrusion and then generate semidiameter this feature with neighbouring position, uses dial gauge contact head and wheel tread
Contact in one week captures wheel fault position, will compare the diameter jump amount measured and specification error value when there is diameter jump, error is excessive
When sound an alarm, remind with vehicle train-examiner record.Data processor can store data, and be transmitted to computer by data line, side
Just train-examiner's record and data reporting.The device avoids the complicated procedures of forming that current detection wheel tread must unload wheel, disappear
Inconvenience when in addition to inspection vehicle, is greatly reduced human and material resources and financial resources.
Compared with prior art, the beneficial effects of the present invention are:
(1) the maximum difference of the present invention and the prior art is not necessarily to individually be detected wheel disassembly, exempts tradition
The multiple tracks complicated procedures of forming of wheel tread is detected in technology.
(2) it data is acquired by sensor is transmitted to data processor and handled and stored, reach error and alarm and remember
Record exports data to computer.
(3) actual conditions at detection scene are combined, the present invention is suitable for the wheel tread of most of model and size, and
It is easy for installation, easy to carry, it is easy to operate, it is objective interface, very clear, the workload of staff is greatly decreased, improves and makees
Industry efficiency.

Fig. 1 is the device of the invention structural schematic diagram.
Fig. 2 is working state figure of the invention.
Appended drawing reference: data processor 1, reset button 2, LED light group 3, acoustic aperture 4, data transmission interface 5, adjustable magnet
6, adjustable magnet button 7, mobile jib 8, data line 9, right angle conversion 10, sensor 11, sensor folder 12, secondary bar 13, gauge stand folder 14,
Dial indicator holder 15, signal wire 16, dial gauge 17, wheel tread 18, wheel 19, bearing 20 can be revolved.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
As shown in Figure 1 and Figure 2, the present invention is by adjustable magnet, magnet knob, data processor, mobile jib, adjustable right angle
Conversion, secondary bar, sensor folder, sensor, gauge stand folder, can revolve dial indicator holder, dial gauge, data line, signal line group at.At data
It manages device 1 and adjustable magnet 6 is interference fitted, block 6 top of adjustable magnet, 8 one end of mobile jib screws in 6 threaded hole of adjustable magnet, separately
One end is caught in right angle conversion 10, and secondary bar 13 is inserted into the other hole of right angle conversion 6, and it is all with bolt fastening, sensing that 6 holes are converted at right angle
Device presss from both sides 12 one end using bolt fastening in secondary bar, and sensor 11 screws in sensor folder 12, can arbitrarily adjust screw-in depth, gauge stand folder
14 are stuck in secondary bar 13 1, can revolve dial indicator holder 15 and be fastenedly connected with gauge stand folder 14, the insertion of dial gauge 17 can revolve dial indicator holder 15
It in hole, and is fastened by bolts, data processor 1 is connected with sensor 11 by data line 9, and sensor 11 passes through signal wire 16
It is connected with dial gauge 17.
Working method of the invention is as follows:
Before starting detection, staff by specification error value Input Data Process 1, bogie enters overhaul library after, work
Make personnel and the adjustable magnet 6 in device is adsorbed on 20 side of bearing, screw mobile jib 8, according to the specification of tested wheel 19, adjustment
Lateral position of the adjustable right angle conversion 10 on mobile jib 8 and the angle that can revolve dial indicator holder 15, enable dial gauge 17 to hang down
Straight contacts with tested 18 zero distance of wheel tread, then tightens the fastening nut at each position, whole device is existed
It keeps stablizing in detection process.Bogie is slowly pushed, wheel 19 is rolled, 17 measuring head of dial gauge is sliding in wheel tread 18
Dynamic, when semidiameter occurs in wheel tread 18,17 measuring head of dial gauge has bounce, and dial gauge 17 reads and data are passed
It is defeated by sensor 11, sensor 11 exports data to data processor 1, and data processor 1 is by the data received and before
The specification error value of input is compared, and when data are greater than specification error value 0.3mm, LED light group 3 sends out a warning, and by acoustic aperture 4
It issues alarm and prompts testing staff, testing staff with label stroke mark position for recording and records alarm on wheel tread 18
Data are inputted terminal by data transmission interface 5 after having detected and read, to know that wheel is that several ranks are polygon by number
The deformation of shape and deflection complete a wheel detection since then, when being detected next time, press reset button 2, data processor
1 data that will test do not store with data field before.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as using the various transformations that the inventive concept and technical scheme of the present invention carry out, or not improved direct application
It is within the scope of the present invention in other occasions.
