Description
Technical field
The utility model relates to the fixation rolling rig of a kind of beeliner, electric locomotive, main line motor-car and subway motor-car.
Background technology
The function of railway electric locomotive or diesel locomotive is the tractor-trailer train operation, and main operating mode is traction and braking; The main operating mode of main line motor-car and subway motor-car also is traction and braking:
One, traction working condition: the electric energy that electric locomotive obtains from electrical network converts mechanical kinetic energy to by traction electric machine after current transformer converts suitable voltage to, and the tractive force that all exportable driver of being subjected to controls under different speed quickens or the stable speed operation train; Diesel locomotive then is earlier to convert the chemical energy of fuel oil to mechanical energy by internal combustion engine to drive the synchronous alternating-current generator generating, pass through current transformer again after, drive the operation of traction electric machine tractor-trailer train.
Two, damped condition: electric locomotive or subway motor-car convert the kinetic energy of train to electric energy by traction electric machine, after conversions such as current transformer, feed back to electrical network.Under different speed, the brake resistance that output is controlled by the driver, thus make train deceleration or speed stabilizing.Diesel locomotive then is to convert mechanical energy to electric energy by traction electric machine, by resistance heating consumption, makes train deceleration or speed stabilizing.
Railway locomotive is the mobile electromechanical equipment that power surpasses 2000kW, and its life cycle was generally 30 years, therebetween will be through repeatedly maintenance.In a single day locomotive breaks down, and will destroy the normal running order of railway, and for guaranteeing locomotive running gear and traction, braking ability, new car and tool car can drop into commencement of commercial operation after all must carrying out the circuit run-in test.
Adopt circuit run-in test mode, the straightforward procedure that traction and braking ability are tested is: adopt 2～3 locomotives to organize into groups, locomotive traction, 1 or 2 locomotive is as accompanying the test-run a machine car to brake in addition, be fixed on corresponding level (only test superlative degree position sometimes) by test locomotive operation handle by the driver, accompany the size of test-run a machine car damping force by change, the control train speed, behind velocity-stabilization, on the instrument system of cab, draw the travelling speed and the tractive force information of corresponding level; Change speed---the tractive force array that the damping force of accompanying the test-run a machine car can obtain other eight left and right sides friction speed points, just obtain a curve of traction characteristics; Change the handle level of tested locomotive again, then can obtain the curve of traction characteristics under another level; Many curve of traction characteristics can the tested locomotive of clear description hauling ability.
During brake test, accompany the test-run a machine car then to export tractive force and drive tested locomotive and advance; Tested locomotive then is in the damped condition of specific system level, converts mechanical energy to electric energy by traction electric machine and realizes braking.Can draw equally the information of tested locomotive running speed and damping force on the instrument system of cab; Accompany the test-run a machine car to regulate the tractive force of car group, obtain the speed about ten---the damping force array promptly obtains a braking characteristic curve; Change tested locomotive handle level, then can obtain an other braking characteristic curve, the braking ability that many braking characteristic curves can the tested locomotive of clear description.
The locomotive slow-speed test can be carried out on several kilometers test wire under factory's section or belt test wire, and the test of rated speed then needs long circuit mileage, thread test just, and positive thread test causes very big pressure to busy road network.Therefore, adopt the fixation rolling rig to replace the selection that is inevitable of circuit running test.
The primary structure and the principle of work of engine static-state rolling rig are: the locomotive two ends are fixed by reaction frame, each of corresponding locomotive taken turns by disposing rail wheel that direct current generator drives to supporting, support the requirement of disalignment apart from locomotive in order to adapt to, equipment such as pair of tracks wheel and motor are formed a mechanical test unit.
During the traction working condition test, traction electric machine driving machine wheel is to rotation, and then drive rail wheel rotation, the direct current generator that links to each other with rail wheel, high-power electric load equipment consumes mechanical energy, for rail wheel provides rotational resistance, regulate the size that electrical load is also promptly regulated rotational resistance, make locomotive wheel be stabilized to different speed points successively, read the speed about ten---the tractive force array, can obtain a curve of traction characteristics, change the traction level of locomotive, can obtain many curve of traction characteristics, according to the curve of traction characteristics that records, can judge whether the hauling ability of tested locomotive is qualified.
During brake test, direct current generator drive track wheel, and then provide rotary power for locomotive wheel, and make it be in specific braking level by the operation locomotive, convert the kinetic energy of locomotive wheel to electric energy feed back to electrical network or by resistance consumption by traction electric machine, and read speed---damping force array under this braking level from the instrument system of cab; And, can obtain ten left and right sides speed---damping force array, and then obtain a braking characteristic curve by regulating the power of direct current generator; Change the braking level of locomotive, can obtain an other braking characteristic curve by the power of regulating the testing table motor again,, can judge whether the braking ability of tested locomotive is qualified by many braking characteristic curves.
The fixation rolling test is convenient, and test condition is controlled, good reproducibility, and high-speed test (HST) safety, the test period is short, and the participant is few, and it is fast to obtain test findings, also can change the gauge of simulation easily.Therefore the fixation rolling rig has obtained extensive utilization in the performance history of the rolling stock, particularly hot-short of nearly half a century.Test of fixation rolling rig and ring road are tested, road test is arranged side by side, become three kinds of modes of locomotive test.
Although testing table significant progress has been arranged, but still there are the following problems through years of development:
1), be arranged at and produce and the testing table of maintenance unit, the general employing gone up vehicle bridge with the method for walking wheel rim testing table up and down, the right wheel rim of locomotive wheel contact with last vehicle bridge rigidity, the stress of wheel rim is concentrated, is easy to generate to be out of shape and crackle; And adopt the mode of tread to get on or off the bus, and then need very complicated utility appliance, could adapt to the placement requirement of locomotive disalignment distance.
2), the torque of locomotive always has the fluctuation more than 5%.Locomotive is at rig-testing, its speed is only embodied by the locomotive wheel rotating speed, car body does not move, therefore the equivalent moment of inertia that is embodied in the traction electric machine spin dynamics equation is reduced to about 1/20 of road test, influenced by it, the unsettled situation of speed may appear in the locomotive closed-loop control system according to the design of circuit operation conditions in the fixation rolling test.The dynamic instability of this locomotive is the major obstacle that realizes electric adjusted in concert precision.
3), the fixation rolling rig is right by separate a plurality of rail wheels, finish in the process of test at two straight rail of endless of simulation, many-sided factor can cause the rotating speed difference that each rail wheel is right, make locomotive think that some takes turns idle running taking place and to its control torque output by mistake, again it is recovered output again subsequently, make the locomotive operation instability; Especially when locomotive starts, will cause output torque frequently to stop, locomotive can not normally be started.Synchronous to the anglec of rotation for guaranteeing each rail wheel, existing testing table adopts bevel gear that all track wheel shafts are tied more, and this makes its mechanical part many, and intermediate connecting shaft is long, testing equipment is complicated, reliability reduces.For the locomotive of the disalignment distance of aliging, numerous mechanical connecting elements also makes its mechanical adjustment work amount big simultaneously, and major axis still causes extraneous vibration and unsafe factor.
Problem in view of the mechanical synchronization scheme, the domestic fixation rolling rig that has adopts the exciting current of regulating each direct current generator, and the scheme that rail wheel is reached unanimity to rotational speed, " diesel locomotive testing table power measurement arrangement governing system " as 1981, this scheme needs the extra observing and controlling closed-loop system that increases, simultaneously since between each traction electric machine of locomotive in the whole traction electric machine parallel connections of " car control " pattern, and 2～3 motor parallels during the frame control, drive by public power, these motors are in speed, the coupled relation that exists common source to bring between the torque, when testing table is regulated the right rotating speed of rail wheel, there is other driving wheel speed of coupled relation also conversion can take place, produces cross interference.And, resistive braking direct current generator mechanical property is very soft, governing speed is slow, when practical application, this scheme need be adjusted repeatedly at concrete locomotive at least, use very inconveniently, the locomotive wheel speed instability problem that simultaneously has such rotation inertia to reduce to bring again will realize that satisfied synchronous rotation is very difficult.
4), need the very powerful examination electrical system of accompanying, the investment height in view of the single bus testing table.At present also there is the scholar to propose the scheme of two engine static-state load feedback rolling rigs: to provide load by another locomotive during a locomotive test, replaced direct current generator and high-power electric load thereof.Two engine static-state load feedback rolling rigs need complicated synchronization mechanism link or external direct current generator to realize that by the adjustment of field excitation mode rail wheel is synchronous, use inconvenience.
5), before locomotive is appeared on the stage, remove the reaction frame of erectting on the ground, after locomotive moves longitudinally to the testing table position, reaction frame is installed again; Driving is all used in moving of reaction frame, and needs to be provided with chain between driving and the contact net.Therefore the test factory building is required height, the test operation complexity is limited by the place, and the fixation rolling rig is difficult to build in existing servicing depot, section.
In a word, existing multimachine car testing table scheme or employing bevel gear are synchronous, or rely on the adjustment of field excitation of direct current generator to realize electric synchronous; During the adjustment of the disalignment distance of the adaptation locomotive that the former carries out before test, workload is very big, and the latter is then in process of the test, because regulating effect is all the time not as people's will, the time cost is also very big.

Like this, when threephase switch ten closures, auxiliary wound asynchronous motor will and be received in the electric axis circuit, if rail wheel changes to reaching the wound asynchronous motor rotating speed that is connected by shaft with rail wheel, to cause the rotor voltage of all motors in the electric axis circuit, frequency changes, the rotation speed change of the flywheel two that the auxiliary wound asynchronous motor of few number of poles and axle thereof connect is bigger, the wound asynchronous motor that connects on the track wheel shaft is the raising speed ratio with the number of poles of auxiliary wound asynchronous motor ratio, make the equivalent inertia of flywheel two increase the raising speed ratio square doubly, thereby the flywheel two that available volume and inertia are all little than flywheel one, make the level that is met or exceeded road test by the moment of inertia of pilot system rotation axis system, with the stability problem of thorough solution static state test.After the off-test, with threephase switch ten disconnections, second auxiliary wound asynchronous motor and flywheel thereof disconnect with the electric axis circuit, and the rail wheel that motor in the electric axis circuit and axle thereof connect finishes test to reaching vehicle wheel to stopping operating quickly.
And, by the flywheel two that is electrically connected access, can realize and being connected and disconnection of electric axis circuit, and separating and combination of realization and rail wheel is simple and convenient by threephase switch ten.The flywheel two that links to each other with motor does not need and the rail wheel mechanical connection, can not increase width even testing table increases flywheel two yet, and flexible cable connects replacement mechanical connection, conveniently moving.
