Description
Technical field
The utility model relates to rolling stock safety technique field, specifically, relates to a kind of bogie solid line derailing experiment table.
Background technology
Because the derail accident is great, can cause the serious consequence of car crash.The correlative study of relevant derail receives the great attention of railway competent authorities always for this reason, also becomes railway, the direction of scientific research personnel's main attack and the focus of research simultaneously.According to statistics, in recent years, the derailing of China goods train is in rising trend, the ratio of derailment accident in the railway major accident up to 70% about, it serves to show urgency and importance to the derailing further investigation.To this, oneself brings major fields and preferential theme in " National Program for Medium-to Long-term Scientific and Technological Development (2006-the year two thousand twenty) " into derailing research.It is thus clear that, carrying out derailing research, to stop or reduce derailment accident, its social effect is very great with economic implications, and its space, technical market is difficult to appraisal.But the theoretical research of derailing mechanism has been a century-old difficult problem, causes the theoretical analysis of the various concrete reasons of derailing, does not also obtain the understanding and the grasp of system at present.Present stage, derailment test is main means with research still still.
At present, the derailment test technology mainly contains single the wheel three kinds of the derailment test of derailment test, whole joint car and bogie derailment tests.
(1) single-wheel is to derailment test: mainly consider a wheel in the bogie to being subjects, testing table adopts single-wheel to the derailment test platform.Take turns being placed in the framework single, will take turns fixing through horizontal and vertical pull bar, again with framework and wheel to making an experiment on the single test unit that is placed on the rolling vibration table together.Through horizontal reinforcing realizes the derailing that wheel is right to framework.This test is all carried out on the rolling vibration table usually; Can not take into full account of the influence of the factor of line conditions such as track irregularity, track camber to derailing; Single-wheel is that wheel contacts with wheel to the derailment test platform; The contact condition and the action characteristic that can not truly reflect wheel track, the actual derailing environment of experimental enviroment and train differs greatly, and lacks authenticity.
(2) derailment test of whole joint car: with a joint car is subjects, generally make an experiment at toroid or black spot, with respect to single-wheel as far as derailment test; The cost of test is high; Dangerous big, test repeatable little, and all can only carry out the low speed derailment test.
(3) bogie derailment test: because bogie derailing experiment can fully reflect the practical function characteristic of wheel track; Test various factors such as travelling speed, track irregularity, track camber etc. are to the influence of derailing, and the repeatability of warranty test reduces empirical risk simultaneously; Shorten the time cycle; Reduce testing expenses, therefore, the derailment test of bogie becomes the main developing direction of derailment test.Yet what existing bogie derailment test platform was directed against all is rectilinear orbit, can't consider the influence of track camber to derailing; And existing testing table generally adopts screw mandrel laterally to load; Its loading velocity is slow, and loading force is less, and the derailing that can't realize jumping onto the tracks etc. are derailment test fast.
Summary of the invention
The purpose of the utility model is to provide a kind of bogie solid line derailing experiment table, overcomes in the prior art bogie derailing experimental provision defective of derailment tests fast such as derailing that can't realize jumping onto the tracks.

Specifically; Said bogie comprises that front-wheel is to right with trailing wheel; Connect front-wheel to the right framework of trailing wheel, be installed on this framework and with front-wheel to the servomotor that is connected through gear drive, be installed on said test with railroad track inboard front-wheel to last axle box, and be installed on the said axle box and the guide wheel mechanism that is connected with horizontal augmentor.
Further, said guide wheel mechanism is made up of the guide wheel, first pole, force cell and second pole that connect in order, and said second pole also is connected through bolt with axle box.
Said guide wheel is connected with the first pole hinge.
Said force cell is a pull pressure sensor.
A nearlyer step ground, said second pole is a T-shape.
Said horizontal augmentor comprises first hold-down support, second hold-down support; One end and second hold-down support are hinged, the other end places on first hold-down support and the horizontal afterburning steel plate of pulley is installed; And end is hinged with first hold-down support, the other end is connected with horizontal afterburning steel plate a hydraulic actuator, said guide wheel is connected with horizontal afterburning steel plate.
Compared with prior art, the beneficial effect of the utility model is:
1. simple, the reliable in structure, easy to use of the utility model principle;
2. the utility model can utilize hydraulic actuator that power is provided, and through cooperating of horizontal afterburning steel plate and guide wheel mechanism, Rapid Realization laterally loads, so realize jumping onto the tracks, derailment test;
3. the utility model is the basis with the warp rail; Multiple factors such as travelling speed in the time of can considering track camber, uneven compliance, derailing simultaneously are to the influence of derailing; Thereby more can demonstrate fully true experimental situation, the actual process of coming to nothing of its experimental result and train is very identical;
4. the utility model has solved in the prior art bogie derailing experimental provision effectively and can't consider the problem to the derailing influence such as track camber, travelling speed; Make the derailing result of experiment meet true environment more; Experimental result is more reliable, has laid solid theory for it is applied to prevent in the true environment derail;
5. the utility model guarantees for research derail mechanism and derailing theoretical analysis provide good technical support and equipment, can produce good social benefit and economic benefit.
