Description

Wheel is to automatic checkout equipment

The utility model relates to railway vehicle wheel to automatic checkout equipment, and this device is applicable to railway, subway, locomotive, the automatic checkout equipment of vehicle wheel to making and overhauling.

At present in the service work of rolling stock, wheel is to producing abrasion owing to moving with rail, the variation of scratch and tread physical dimension, therefore need periodic inspection and reparation, and the prior art of using at present is to adopt artificial use to measure action to change, with relatively method and special-purpose slide calliper rule come measuring pulley footpath and abrasion, at first, this method of measurement reacts the variation of wheel footpath because changing with the measurement action, therefore be a kind of approximate value, thereby can not truly reflect actual conditions, on the other hand owing to be to use multiple measurer in very short time, to record data more than eight kinds with artificial, take turns filing for reference as data on the regulation form but also must fill in each, therefore not only labour intensity is big, efficient is low, add the error that human element produces, therefore become the key and the difficult problem of car inspection and maintenance department for many years always, constantly the above-mentioned contradiction of speed-raising is more outstanding to add train.At existing problem in the above-mentioned prior art, advanced person's the automatic detection wheel that designs a kind of novelty is to physical dimension and measurement of wear device, and man-machine interface close friend is simple to operate, and the detecting device of noting down, printing, file, report to the police automatically, carry out automatic management.Thereby overcome present existing problems is very necessary.

The purpose of this utility model is the problem at above-mentioned prior art existence, break existing traditional measurement method and instrument and propose to design a kind of the wheel automatic checkout equipment, it utilizes the photoelectronic imaging technology, use CCD linear array and the imaging of face battle array and infrared technology to give full play to the performance of computing machine, automatic guidance, automatically calculate, store automatically and print related data, be convenient to technical supervision.

The purpose of this utility model is achieved in that a kind of the wheel automatic checkout equipment, and wheel is connected successively to spacer assembly, prediction unit, proving installation, and all communicates with computer interface.

Wherein, wheel is that cylinder links to each other with arm to the structure of spacer assembly, and arm is captiveed joint with shifting shaft, and shifting shaft is connected with the isolation arm.

Wherein, the structure of prediction unit is that support roller, motor and coupled chain drive-belt and sprocket wheel are formed rotating mechanism, and is installed on the area array CCD camera predicted composition mechanism between two support rollers, and cylinder and cylinder are formed release and the anti-mechanism of going out.

Wherein, proving installation is, holding up mechanism's locating piece is connected with the rod end that holds up hydraulic ram, the left and right sides is provided with the line array CCD camera above picking-up mechanism, stepping motor makes line array CCD camera and light source motion thereof by coupled precision drive leading screw, constitutes wheel tread size detection mechanism; Stepping motor drives the line array CCD cam movement by coupled precision drive machine thick stick, constitutes the testing agency of wheel shaft diameter; Wheel is linked to each other with chain with sprocket wheel by the cycloidal-pin wheel retarder of translator to rotating mechanism and forms, and releases cylinder and positioning cylinder and forms and release and detent mechanism; Above mechanism all is fixed in and measures on the frame.

The utility model novel structure, advanced in performance, efficient is high, labor content is little, error is little, be the non-contact measurement device.

Below in conjunction with drawings and Examples the utility model is further detailed.

As shown in Figure 1, owing to isolate the effect of arm 2, will treat that measuring wheel to being isolated in beyond the test section, prevents to take turns mutual interference mutually with being subjected to inspection in the test section.

Shown in Fig. 2 A, Fig. 2 B, when wheel will be taken turns pushing proving installation by cylinder (5) after detection finishes in prediction unit, at this moment, room, prediction unit place, by the effect of isolating cylinder 1, pusher arm 21 drives shifting shaft 29 rotations, and fixing respectively isolation arm 2 will be taken turns dialling in prediction unit at the two ends of shifting shaft 29, wheel will be taken turns being positioned (Fig. 2 B) in the support roller 3 by four support rollers 3 entering prediction unit.Be fixed in the area array CCD camera 7 of wheel to the spindle nose two ends, identification is taken turns spindle nose information respectively, and shows that the record wheel is to historical summary.Be fixed in the area array CCD camera 13 of wheel to the centre, self-measuring goes out wheel rim thickness, by translator cycloidal-pin wheel retarder 4 chain drive-belts 22 and sprocket wheel 23, drives the support roller 3 that is fixed on two ends, make wheel to slow rotation, thereby detection wheel is to flat sliding and peel off situation.The prediction back that finishes will be taken turns being pushed into detecting device by releasing cylinder 5, positioning cylinder 6 be prevent by spacer assembly push wheel to the time unlikely going out.

As Fig. 3 A, shown in Fig. 3 B, wheel is to entering proving installation, to take turns being positioned (Fig. 3 B) in the support roller 8 by positioning cylinder 12, this moment, two ends, the left and right sides held up the hydraulic ram 27 of mechanism, promote locating piece 11, to take turns simultaneously from support roller 8, holding up, to certain altitude, locate, be fixed in the line array CCD 19 and the light source 28 (Fig. 3 A) of each one group measurement tread size about measuring on the frame 10, with the line array CCD 20 of measuring wheel seat axle and axle mid-diameter, with light source 26, respectively by stepping motor 15,17 drive, joining precision drive leading screw 16 and 18 rotates, drive line array CCD camera 19 simultaneously, 20 motions, and measure relative dimensions with 100 measuring speeds of per second, reach in the computing machine and calculate, measure the back line array CCD camera 19 that finishes for the first time and in time return the original place, wheel is to by hydraulic actuating cylinder 27, to take turns and drop to (Fig. 3 B) on the support roller 8 holding, by translator cycloidal-pin wheel retarder 14 drive sprockets 24 and chain 25, thereby driving two ends support roller 8 rotates, after making wheel to corresponding half-twist, to take turns holding up once more by locating piece 11 and picking-up oil cylinder 27 again to original height, measure by line array CCD camera 19 once more, with about carrying out computing in size and the quantitative data input computing machine, draw the wheel footpath, wheel rim is thick, distance between backs of wheel flanges, tread wear, wheel rim is wide, and wheel seat shaft diameter, shaft diameter in the axle, show that also output print is to form, the measurement butt that finishes plays mechanism and drops to once more in the support roller 8, to take turns releasing by cylinder 9, whole said process is automatically controlled fully, judges whether remanufacturing or scrap of wheel tread according to the relevant data that prints form.

This detecting device can use separately, the software management system of industrial computer also can participate in taking turns the typing of data such as press-fiting of right ultrasonic flaw detection, the flaw detection of electromagnetism remanent magnetism, spindle nose bearing, formation is to the monitoring of wheel to the maintenance overall process, reaches that wheel is controlled in order to overhauling, repair quality is stable, wheel is to the guaranteed purpose of entrucking safety.
