Description
Technical field
The present invention relates to a kind of test platform, relate to specifically a kind of rail milling car test platform.
Background technology
High-speed railway, subway and inter-city train, at the positive high speed development of China, have proposed harsh requirement to indexs such as the surfaceness of rail and smooth degrees.Adopt the mode of milling car, milling machine and grinding machine are hung upside down in train bottom, by train, drive milling car to advance, first adopt profile milling cutter wheel to carry out high-speed milling, then adopt wide abrasive wheel forming grinding, eliminate Milling Process error and moulding interface water caltrop, improve surfaceness and the smooth degree of rail, this milling car replaces rail grinding train gradually becomes the Main Means that railway track is repaired.Due to the restriction of railway carrying capacity, debugging test milling car performance and technical indicator cannot be tested for a long time aboard.
In order to ensure the safe and efficient work of milling car, can only set up huge test platform, by the reversal of the natural order of things of milling car, on test platform, simulation milling car duty realizes the test of milling turnning and milling mill.During milling turnning and milling mill rail, have the operating modes such as craspedodrome, turning, upward slope, descending, so this test structure is complicated, the place of test is huge, with high costs.For this reason, need to study a kind of perfect in shape and function, the test platform of simple in structure and low in cost, for the debugging of rail milling vehicle device provides strong experimental technique support with research.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and a kind of perfect in shape and function, rail milling car testing table simple in structure, with low cost are provided, can simulate operating mode and the work behavior of milling turnning and milling mill rail, for the experimental study of milling car grinding attachment.
A kind of rail milling car testing table, comprise test platform frame, the bottom of described test platform frame is arranged on test platform by the first adjusting gear of test platform frame degree of tilt described in capable of regulating, rail milling car is installed on the crossbeam of described test platform frame, on described test platform, below described rail milling car, be provided with guide rail, the guide rail car driving by propulsion system is installed on described guide rail, on described guide rail car, be provided with described rail milling turner and make the corresponding rail test specimen of end position, described rail test specimen is arranged on described guide rail car by the second adjusting gear of adjustable described rail test specimen gauge.
In the present invention, described test platform frame comprises described crossbeam, bearing and side stand component, described the first adjusting gear is the first adjustment parallels, described bearing is arranged on described test platform by the first adjustment parallels, and passive described side stand component is connected with described test platform with described support.
In the present invention, described the second adjusting gear is the second adjustment parallels, and described rail test specimen is arranged on described guide rail car by the second adjustment parallels.
Adopt such scheme, operating mode when this device has been simulated milling turnning and milling mill accurately, is converted to by body movement the motion that guide rail car drives rail test specimen, and the movement inertia of moving component reduces greatly, has reduced cost and simulation difficulty; By the adjusting of parallels and gauge, tested the simulation of each operating mode of milling car, greatly saved test site, allow milling test not limited by place, because rail milling car is fixed on crossbeam motionless, greatly reduce the requirement of the intensity and toughness of testing table own, the quality of moving component reduces greatly, has improved the security of test.
In sum, this apparatus function is perfect, and the test platform of simple in structure and low in cost, for the debugging of rail milling vehicle device provides strong experimental technique support with research.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is structural representation of the present invention.
Fig. 3 is stereographic map of the present invention.
Embodiment
Below in conjunction with accompanying drawing, describe a kind of embodiment of rail milling car testing table in detail.
As Fig. 1,2,3, a kind of rail milling car testing table comprises test platform frame and feed arrangement, and test platform frame comprises crossbeam 1, bearing 2, side stand component 8 and the first adjustment parallels 9.Feed arrangement comprises rail test specimen 4, foundary weight 5, guide rail car 7 and the second adjustment parallels 6.
3 reversals of the natural order of things of rail milling car are on crossbeam 1, first adjusts parallels 9 is fixed on the ground by foot bolt, bearing 2 is arranged on the first adjustment parallels 9, and rail test specimen 4 is fixed on the second adjustment parallels 6 by briquetting, and second adjusts parallels 6 integral body is fixed on guide rail car 7.
During 3 work of rail milling car, there are three kinds of operating modes: the milling of normally travelling, turning milling, the milling of upward slope descending.
The milling of normally travelling: rail milling car 3 is fixed on testing table crossbeam 1, the emery wheel of rail milling car 3 working ends is High Rotation Speed under servomotor drives, meanwhile guide rail car 7 drives by the low-tension supply of lower guideway 10, realize the feed motion of this experiment, guide rail car 7 moves along lower guideway 10, realizes the rail grinding that simulation train normal row is sailed.
Turning milling: the gauge wide (specifically widen ratio and have GB in Table 1) while normally travelling due to train turning gauge ratio, simulation train just must also add broad gage while turning.By regulating the second adjustment parallels 6, adjust the gauge of rail test specimen 4, for example normal running rail inner distance is 1435mm, when radius of curvature R <300mm, gauge need to be widened 15mm, by regulating the second adjustment parallels 6 can be by the outside mobile 7.5mm respectively of rail test specimen, experiment gauge just becomes 1450, other motions with normally travel identically, realize the simulation of turning operating mode.
Table 1 widening of curve
| Sweep (m) | Widen value (mm) | Gauge (mm) |
| R≥≥350 | 0 | 1435 |
| 350>R≥300 | 5 | 1440 |
| R<300 | 15 | 1450 |
Climb and fall simulation: every bearing 2 is lined with four first below and adjusts parallels 9, as required, by first of one end of bearing 2 belows, adjusting parallels 9 heightens, the other end first is adjusted parallels 9 and is turned down, two the bearing 2 adjustment modes in left and right are identical, experiment table bearing 2 understands with rail milling car 3 integral body the angle that tilts like this, and guide rail car 7 angles of feed motion are constant, grinding speed direction and direction of feed just have an angle like this, other are identical during with normal work, have so just realized the simulation of climb and fall operating mode.
The simulation of milling car work behavior: rail milling car 3 integral hangings, on test platform frame, can be realized the simulation of the work behaviors such as feed, withdrawing, stroke limit.
