Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that this embodiment is not limited to for illustration of the utility model limit scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.In the present embodiment, said front, rear, left and right are all reference with Fig. 2, in fig. 2, are parallel to paper left for front, and be parallel to after paper is to the right, be outwards left perpendicular to paper, is inwardly the right side perpendicular to paper.
As shown in Fig. 1 ~ Fig. 5, this steel rail web two-wheel of the present embodiment sander comprises a support 1, in this example, this support 1 is welded by the metal sheet of many square tubes and one piece of U-shaped, the bottom of support 1 is provided with one in front and one in back and two walking rollers 2 of column distribution, during practical application, these two walking rollers 2 are supported the top walking of rolling along the longitudinal direction that are placed on track a, thus band engine-bed 1 is movable on track a.Conveniently operator applies thrust or the pulling force of forward/backward to support, and this example is also fixedly installed the hand push frame 9 of inverted u-shaped on support 1.This hand push frame 9 is that the metal circular tube of employing three distribution in U-shaped is welded.
Above-mentioned support 1 is connected with and can opens/V-shape the tensioning frame 3 of tensioning action along left and right horizontal direction.In this example, this tensioning frame 3 is made up of the connecting rod (not marking in figure) that two are arranged in V-shape, these two connecting rods have closing end (the i.e. tip of " V " word bottom close to each other, the right-hand member of connecting rod in Fig. 4) and mutually away from dehisce hold (the i.e. openend on " V " word top, the left end of connecting rod in Fig. 4), and the closing end of two connecting rods can be hinged on described support 1 in left and right turningly.
Tensioning frame 3 is provided with the rate of tension governor motion 4 that can control this tensioning frame 3 rate of tension.In this example, this rate of tension governor motion 4 comprises the worm screw 401 be connected with above-mentioned two connecting rods and the handwheel 402 being fixedly connected on this worm screw 401 one end.Connection fit system concrete between worm screw 401 and above-mentioned two connecting rods can refer to shown in Fig. 1 and Fig. 4: worm screw 401 is provided with two rotatable regulating wheels 12, and these two regulating wheels 12 are arranged in the outside of two connecting rods forming tensioning frame 3, when user drives worm screw 401 to rotate by handwheel 402, can make these two regulating wheels 12 close to each other along left and right horizontal direction/away from, when these two regulating wheels 12 are close to each other, it is close to each other that two regulating wheels 12 just can extrude two connecting rods forming tensioning frame 3, and then drive tensioning frame 3 to dehisce to hold two emery wheels 5 (seeing below) arranged close to each other, clamp rail web.
Tensioning frame 3 is also provided with two emery wheels 5 that can rotate, these two two emery wheel 5 one the first from left right septum distributions.Specifically, these two emery wheels 5 are arranged on the end of dehiscing of above-mentioned two connecting rods.Be more specifically that the dehiscing to hold of described two connecting rods is all fixedly installed the axle sleeve 10 of vertically distribution, in this axle sleeve 10 rotary setting have vertically distribution and the axis of rotation 11 outside axle sleeve is all stretched out at its upper and lower two ends, emery wheel 5 is coaxially fixed on the lower end of axis of rotation 11.During in order to make polishing operation, emery wheel 5 is made to be close to steel rail web, ensure the laminating degree between emery wheel 5 and steel rail web and the polishing quality to steel rail web, emery wheel 5 in this example adopts centrifugal emery wheel, centrifugal emery wheel makes the outside elastic dilatation of its outer peripheral edge plane of rotation when rotating owing to being subject to centrifugal force, thus is adjacent to steel rail web all the time.This emery wheel also can adopt the elastic grinding wheel be made up of elastomeric material.
This sander also comprises drive unit 6, and this drive unit 6 is in transmission connection with these two emery wheels 5 above-mentioned, rotates thus polish to rail web to drive emery wheel.This drive unit 6 can be motor, can be also diesel engine, and what adopt in this example is motor, is preferably servomotor.
In the present embodiment, turn round belt 7 by two between described drive unit (i.e. motor) and described two emery wheels 5 to be in transmission connection, have two revolution belts 7, to be used for connecting motor and first emery wheel 5, another is used for connecting motor and second emery wheel 5.On tensioning frame 3, rotary setting has at least two belt pulleys 8 be in transmission connection with described revolution belt 7, and the quantity of belt pulley 8 described in this example is specially four, as Fig. 1 and Fig. 4.Two belt pulleys 8 are wherein had coaxially to be fixed on the upper end of described two axis of rotation 11, as Fig. 1.When described motor rotating operation, drive described two emery wheels 5 to make rotating in same direction by described revolution belt 7, as shown in Figure 6, these two emery wheels 5 all rotate clockwise in figure 6.
Again shown in composition graphs 1 ~ Fig. 5, now the operating principle of this for the present embodiment steel rail web two-wheel sander is simply described below:
During use, first move up this sander entirety on the rail needing polishing, and make bottom support 1 two walking rollers 2 be supported on above rail a, now two emery wheels 5 lay respectively in the left and right sides of rail a.Manual rotation handwheel 402 rotates to drive worm screw 401 thereupon, and then make two connecting rods forming tensioning frame 3 close to each other, thus two of the left and right sides of rail a emery wheels 5 are adjacent to and clamp that (and non-fully folder is dead, when promoting support 1, two emery wheels 5 still can move forward and backward relative to rail) steel rail web.Open the motor as drive unit 6 afterwards, under the drive of motor, two revolution belts do clockwise equidirectional/rotate counterclockwise, and then drive two emery wheels 5 do equidirectional rotating clockwise at Fig. 6, rail web is polished.Thus, these two emery wheels 5 will produce the contrary power in one group of equal and opposite in direction, direction to rail, rail a also can produce contrary reaction force---F1 and F2 in one group of equal and opposite in direction, direction to these two emery wheels 5, these two reciprocal power F1 and F2 produce one group of relative moment of torsion, thus two emery wheels 5 can step up track a to all-the-time stable when making work, vibrate little and safety is high, work very stable.In the process that these two emery wheels 5 pairs of rail web are polished, operating personnel can promote/pull the hand push frame 9 on support 1 and then drive complete machine forward/backward to move, and complete the polishing to each length section of track, ultrahigh in efficiency.
In figure 6, F1 represents the reaction force of track to left side emery wheel, and F2 represents the reaction force of track to right side emery wheel, and W represents the width at rail web place.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
