Description
Technical field
The present invention relates to a kind of test platform, relate to a kind of rail milling car test platform specifically.
Background technology
High-speed railway, subway and inter-city train be at the positive high speed development of China, and the indexs such as surfaceness peace compliance of rail have been proposed harsh requirement.Adopt the mode of milling car; Milling machine and grinding machine are hung upside down in the train bottom, drive the milling car by train and advance, adopt profile milling cutter to take turns earlier and carry out high-speed milling; Adopt wide abrasive wheel forming grinding then; Eliminate Milling Process sum of errors moulding interface water caltrop, improve the surfaceness peace compliance of rail, this milling car replaces the steel rail grinding train gradually becomes the main means that railway track is repaired.Because the restriction of railway carrying capacity, debugging test milling car performance and technical indicator can't make an experiment for a long time aboard.
In order to ensure the safe and efficient work of milling car, can only set up huge test platform, on test platform, simulation milling turner is made state and is realized the test of milling turnning and milling mill with the reversal of the natural order of things of milling car.During milling turnning and milling mill rail operating modes such as craspedodrome, turning, upward slope, descending are arranged, so this test structure is complicated, the place of test is huge, and is with high costs.For this reason, need a kind of perfect in shape and function of research, the test platform of simple in structure and low in cost is for the debugging of rail milling vehicle device provides strong experimental technique support with research.
Summary of the invention
The objective of the invention is to overcome the deficiency of 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 the operating mode and the work behavior of milling turnning and milling mill rail, be used for the experimental study of milling car grinding attachment.
A kind of rail milling car testing table; Comprise the test platform frame; The bottom of said test platform frame is installed on the test platform through first adjusting gear that can adjust said test platform frame degree of tilt; Rail milling car is installed on the crossbeam of said test platform frame, below said rail milling car, is provided with guide rail on the said test platform, the guide rail car that drives through propulsion system is installed on the said guide rail; Said guide rail car is provided with said rail milling turner and makes the corresponding rail test specimen of end position, and said rail test specimen is installed on the said guide rail car through second adjusting gear of the said rail test specimen of scalable gauge.
Among the present invention; Said test platform frame comprises said crossbeam, bearing and side bracing frame; Said first adjusting gear is the first adjustment parallels; Said bearing is installed on the said workbench through the first adjustment parallels, and passive said side bracing frame is connected with said workbench with said support.
Among the present invention, said second adjusting gear is the second adjustment parallels, and said rail test specimen is installed on the said guide rail car through the second adjustment parallels.
Adopt such scheme, the operating mode when this device has been simulated milling turnning and milling mill accurately converts body movement into motion that guide rail car drives the rail test specimen, and the movement inertia of moving component reduces greatly, has reduced cost and simulation difficulty; Tested the simulation of each operating mode of milling car through the adjusting of parallels and gauge; Saved the test site greatly; Let milling test not limited by the place,, reduce the requirement of the intensity and toughness of testing table own greatly because that rail milling car is fixed on the crossbeam is motionless; 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 is for the debugging of rail milling vehicle device provides strong experimental technique support with research.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is a stereographic map of the present invention.
Embodiment
Below in conjunction with accompanying drawing, specify a kind of embodiment of rail milling car testing table.
Like Fig. 1,2,3, a kind of rail milling car testing table comprises test platform frame and feed arrangement, and the test platform frame comprises crossbeam 1, bearing 2, side bracing frame 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; The first adjustment parallels 9 is fixed on the ground through foot bolt; Bearing 2 is installed on the first adjustment parallels 9, and rail test specimen 4 is fixed on the second adjustment parallels 6 through briquetting, and the second adjustment parallels, 6 overall fixed are to guide rail car 7.
Three kinds of operating modes are arranged: cruising milling, turning milling, the milling of upward slope descending during 3 work of rail milling car.
The cruising milling: rail milling car 3 is fixed on the testing table crossbeam 1; The emery wheel of rail milling car 3 working ends is high speed rotating under servomotor drives; Meanwhile guide rail car 7 drives through 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 of simulation train cruising.
The turning milling: because the gauge wide (specifically widen ratio have GB see table 1) of train turning gauge during than cruising, the simulation train just must also add broad gage when turning.Adjust the gauge of rail test specimen 4 through regulating the second adjustment parallels 6; For example cruising guide rail inner distance is 1435mm; < gauge need be widened 15mm during 300mm, can the rail test specimen outwards be moved 7.5mm respectively through regulating the second adjustment parallels 6, and the experiment gauge just becomes 1450 in radius of curvature R; Other motions are identical with cruising, realize the simulation of turning operating mode.
Table 1 is imprisoned the line slacking of gauge
Climb and fall simulation: be lined with four first adjustable sizing blocks 9 below the every bearing 2; As required, first adjustable sizing block 9 of an end of bearing 2 belows is heightened, the other end first adjustable sizing block 9 is turned down; About two bearing 2 adjustment modes identical; Experiment table bearing 2 is understood the angles that tilt with rail milling car 3 integral body like this, and guide rail car 7 angles of feed motion are constant, and grinding speed direction and direction of feed just have an angle like this; Other are identical during with operate as normal, have so just realized the simulation of climb and fall operating mode.
The simulation of behavior is done in the milling turner: rail milling car 3 integral hangings can be realized the simulation of work behaviors such as feed, withdrawing, stroke limit on the test platform frame.
