Description
Technical field
The utility model relates to a kind of wheel detector, relate in particular to the 4th kind of A type checking device of a kind of railway motor train unit wheel and locomotive car wheel, be used to measure the wheeling edge wearing of railway motor train unit wheel and locomotive car wheel, a kind of special measurement measurer of tread wear equivalent damage degree belongs to the wheel detection technical field.
Background technology
Railway is a means of transport in a kind of modern age, is the instrument that transports passenger and goods in a large number.Especially in recent years the fast development of China Express Railway, speed per hour surpasses 300 kilometers/hour a large amount of the travelling in China big ground from all directions of railway motor train unit.Therefore, the security relationship of railway national economy, is concerning the safety of people's lives and properties, and is also closely bound up with the equipment of railway and operating personnel's safety.Flourish day by day along with railway industry, increasing advanced detection technique is applied among the manufacturing and maintenance of railway motor train unit wheel and locomotive car wheel, these technology can be found the fault of parts effectively, eliminate the hidden danger of fault in time, prevent the generation of accident.Because wheel is to orbit, and produces certain wearing and tearing, and causes damage to wheel.1), wheel tread wearing and tearing its damage type mainly contains:; 2), wheel wear; 3), wheel rim, the friction of tread wound are hindered ... etc. the damage of aspect, wherein with 1), the wheel tread wearing and tearing; 2), wheel wear is main damage.
1), wheel tread wearing and tearing: this is because whole load of rolling stock all pass to rail through wheel, and during the rolling stock operation, wheel is rolling constantly on rail, and wheel tread and track form a pair of friction pair.The wearing and tearing of so-called tread, be meant locomotive be in operation startups, parkings, increase and decrease speed and emergency brake etc. not uniform motion to wheel formation wear and tear.
2), wheel wear: under wheel tread serious wear situation, make wheel to and rail between relative position undesired, then take turns circuit one side relatively, make the wheel rim eccentric wear.1., flange thickness reduces wheel wear has three kinds of forms:.2. wheel wear forms cutting edge.3., wheel rim vertically weares and teares.
This shows that the wheel rim of wheel and tread are the main abrasion positions of rolling stock traveling, the wheel running quality requires very strict, needs running check, measures and revises.
In the prior art, China's utility model patent of invention ZL00253776.1 (August 15 calendar year 2001 Granted publication day) instructions " wheel rim tread linkage checker " has disclosed a kind of wheel rim of measuring locomotive and wheel, the structure of the detector of the tread wear degree of depth, this detector is by basic chi, sliding sleeve, tread wear surveys chi and wheeling edge wearing is surveyed the chi formation, the base chi comprises vertical section and horizontal segment, sliding sleeve is sleeved on the basic chi horizontal segment and can horizontally slips, it is T-shaped that tread wear is surveyed chi, its vertical section is sleeved in the vertical sliding sleeve groove of sliding sleeve and can slides up and down, and its bottom is provided with gauge head; Wheeling edge wearing survey chi is sleeved in the tread wear inspection horizontal segment horizontal concrete chute and can horizontally slips therein.The front end that is positioned at wheeling edge wearing survey chi is provided with gauge head up and down.
Use above-mentioned detector to measure in wheeling edge wearing and the tread wear process, because it is fixed form that wheeling edge wearing is surveyed the fit of the gauge head up and down of chi, two fixed gauge heads are respectively applied for and detect vertical flange and flange thickness, last gauge head detects vertical flange, following gauge head detection wheel edge thickness.When detecting the wheel rim of heavy wear situation, or during the big wheel rim of detection of vertical abrasion value, both testing processes interfere with each other phenomenon, that is: generally when measuring, following gauge head is near tested wheel rim and measure flange thickness numerical value, do not contact tested rim faces and go up gauge head, can only estimate tested wheeling edge wearing situation with eye, therefore cause measuring result error bigger, more serious problem is, when vertical flange is big, last gauge head contact tested surface, and when down gauge head did not also touch tested surface, both disturbed, and do not check the flange thnickness abrasion situation.Particularly the motor train unit wheel rim vertically wears away and detect to require big distance, big gradient (Qp value) measurement point, and can read measurement data more become impossible.
Shipping office of The Ministry of Railway of the People's Republic of China, MOR had issued " No. [2009] 425, fortune dress passenger vehicle " file in 2009, file is printed and distributed the notice of " motor train unit wheel rim tread measuring basis and portable measurer review comment " "; the notice middle finger goes out motor train unit wheel rim tread Qp value utilization limit greater than 6.5mm, and this shows that the Ministry of Railways proposes new standard and high-quality requirement at motor train unit wheel rim tread measuring basis and abrasion.
Therefore, railroad survey measurer industry is demanded urgently developing and is had the location reliably at present, measures accurately a kind of detector that can be applicable to railway motor train unit wheel and the 4th kind of A type of locomotive car wheel that measuring accuracy is high.
