Technical field
This utility model relates to a kind of railway locomotive repair apparatus, more specifically, it relates to a kind of wheel is to running-in testing machine.
Background technology
The wheel of the locomotive travelled on railway is made up of wheel shaft, wheel and bearing, industry is referred to as wheel right.After locomotive driving a period of time, it is necessary to upper bearing is overhauled by wheel, and traditional detection repair method is only to get off to detect by bearing removal, carries out break-in process after having overhauled again, again bearing reduction is assembled on wheel shaft afterwards.This maintenance mode there is the problem that, in the process being assembled on wheel shaft by bearing reduction, the inside and outside circle fit clearance of bearing is susceptible to change, and causes the axiality of wheel shaft also to change so that maintenance effect is on the low side.
Notification number is the Chinese patent of CN103862221A, disclose a kind of wheel set bearing running-in machine, its operation principle is: is first reduced by the bearing of maintenance completion and is assembled on axletree, take turns carrying out break-in process to whole again, avoid bearing clearance change in assembling process, solve the fit clearance of the wheel set bearing existing for former repair method and be easily changed and the problem of repair quality difference of wheel set bearing.
With reference to Fig. 1, take turns to bearing be the bottom being arranged at locomotive by special installing rack, and in order to ensure antiwhip, bearing is extremely complex with the mounting structure of installing rack.But the wheel set bearing running-in machine that above-mentioned patent provides, only it is provided with bearing block, say, that when maintenance, it is necessary to by installing rack with wheel to separating.After wheel is complete to break-in, installing rack is ressembled.In the process ressembled by installing rack, owing to the fixed structure of bearing and installing rack is complicated, after repeated removal, the fitness of the bearing that can make and installing rack reduces, therefore, by wheel to installing rack assemble complete after, it is still desirable to carry out certain break-in.But, the wheel set bearing running-in machine that above-mentioned patent provides, only it is provided with bearing block, can only to wheel to carrying out break-in test, it is impossible to carry out taking turns the break-in to installing rack.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of wheel to running-in testing machine, it is possible to realize wheel to the break-in with installing rack simultaneously.
For achieving the above object, this utility model provides following technical scheme:
A kind of wheel is to running-in testing machine, including frame, it is arranged on frame both sides and for fixing the fixed mechanism of train wheel, for driving wheel to rotate wheel to rotating mechanism, and Hydraulic Station, it is characterized in that, described fixed mechanism includes: be separately positioned on frame both sides for hold take turns to installing rack bottom supporting seat, and after being placed on supporting seat at described installing rack, be pressed in the hold-down mechanism of supporting seat.
Further, the mounting groove that described supporting seat includes bottom two pillars, described pillar and described installing rack is suitable.
Further, described hold-down mechanism includes: be respectively arranged at frame both sides, and in two oil cylinders being vertically arranged, the expansion link of two oil cylinders upward, is respectively arranged at the pole of frame both sides, and is respectively arranged at two pivoted arms of the upper end thereof of two poles；The arm body of described pivoted arm and the upper end thereof of corresponding pole, an end of described pivoted arm is hinged with the expansion link of the oil cylinder being in frame the same side, and another end of described pivoted arm is provided with the briquetting for pushing down installing rack top.
Further, rotating mechanism is included by described wheel: motor cabinet two pieces hinged with frame, it is separately fixed at the motor on two motor cabinets, is vertically arranged to the oil cylinder in frame, and respectively two motor cabinets is constituted two hinged connecting rods with the end of the piston rod of oil cylinder.
Compared with prior art, the utility model has the advantages that: by above technical scheme, can directly the wheel equipped with installing rack to being placed on submounts, then by this hold-down mechanism, installing rack is firmly pressed against on base, so, can not only realize bearing and wheel to break-in, additionally it is possible to realize wheel for the break-in of installing rack.
