Abstract
The utility model relates to a kind of high speed railway track measuring instrument position limitation protection type directive wheel.Detection for railroad track smooth degree adopts rail measuring apparatus to carry out more, the road wheel side of this instrument is provided with the directive wheel being positioned at rail measurement and leads to advancing of rail measuring apparatus, and easily because of collision, breakage even comes off to run into rail gap in the process of walking.The utility model comprises the wheel body of axle and shaft end; The axial both sides of axle are provided with symmetrical, L-shaped axle sleeve, coated whole axle, and axle sleeve top is positioned at wheel body side, and wheel body opposite side is provided with wheel cover plate, and wheel cover plate and axle sleeve top are by bolt consolidation; Wheel body diameter is greater than the width at wheel cover plate and axle sleeve top.The utility model by arranging operator guards outside directive wheel; carry out spacing to the position of directive wheel, avoid going when meeting rail gap damaged because of collision, in addition overall wheel design is served to the effect of insulation; improve safety and the accuracy of measurement, extend the application life of directive wheel simultaneously.
Description
Technical field
the utility model belongs to railroad survey technical field, is specifically related to a kind of high speed railway track measuring instrument position limitation protection type directive wheel.
Background technology
The smooth degree of railroad track refers to that the height that track is occurred rises and falls and left and right offsets, and affects the normal traveling of train because train orbits and the change of track bed for a long time.Along with improving constantly of train running speed, for realizing safety and the comfortableness of train operation, particularly the ride comfort of high speed railway track directly affects the safety of bullet train with steady, the design and construction of circuit must accomplish high ride, railroad requires more and more higher to railway irregularity state parameter, therefore particularly seems important to the detection of rail smooth degree with maintenance.
At present, detection for railroad track smooth degree adopts the mode of track geometry status measuring instrument to carry out more, i.e. rail measuring apparatus, the road wheel side of this instrument is provided with the directive wheel being positioned at rail measurement and leads to advancing of rail measuring apparatus, easily because of collision, breakage even comes off to run into rail gap in the process of walking, and in addition, the axle of directive wheel is generally metal material, there is the phenomenon that is energized in easy and rail, the safety that impact is measured.
Summary of the invention
The purpose of this utility model is to provide a kind of high speed railway track measuring instrument position limitation protection type directive wheel, plays insulation, protection and spacing effect to directive wheel.
The technical scheme that the utility model adopts is:
A kind of high speed railway track measuring instrument position limitation protection type directive wheel, is characterized in that:
Comprise the wheel body of axle and shaft end;
The axial both sides of axle are provided with symmetrical, L-shaped axle sleeve, coated whole axle, and axle sleeve top is positioned at wheel body side, and wheel body opposite side is provided with wheel cover plate, and wheel cover plate and axle sleeve top are by bolt consolidation;
Wheel body diameter is greater than the width at wheel cover plate and axle sleeve top.
The monosymmetric axle sleeve of axle is fixed by the set bolt through axle.
Axle bottom along rail to symmetrical both sides be provided with stop pin.
The utility model has the following advantages:
The utility model by arranging operator guards outside directive wheel; carry out spacing to the position of directive wheel, avoid going when meeting rail gap damaged because of collision, in addition overall wheel design is served to the effect of insulation; improve safety and the accuracy of measurement, extend the application life of directive wheel simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model assembly state diagram.
In figure, 1-takes turns cover plate, 2-wheel body, 3-axle sleeve, 4-stop pin, 5-axle, 6-set bolt, 7-wheel design, 8-road wheel, 9-road wheel motor.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
A kind of high speed railway track measuring instrument position limitation protection type directive wheel that the utility model relates to, the directive wheel on matching track measuring instrument uses, and comprises the wheel body 2 of axle 5 and axle 5 end, and wheel body 2 carries out spacing along the walking of rail side.The axial both sides of axle 5 are provided with symmetrical, L-shaped axle sleeve 3, coated whole axle 5, and axle sleeve 3 top is positioned at wheel body 2 side, and wheel body 2 opposite side is provided with wheel cover plate 1, and wheel cover plate 1 and axle sleeve 3 top are by bolt consolidation.The monosymmetric axle sleeve 3 of axle 5 is fixed by the set bolt 6 through axle 5.Overall structure is coated with wheel cover plate 1 by axle sleeve 3, because axle sleeve 3 and wheel cover plate 1 have employed nylon material, the axle 5 of metal material can be protected, play the effect of insulation.
In addition, wheel body 2 diameter is greater than the width at wheel cover plate 1 and axle sleeve 3 top, facilitates wheel body 2 in the walking of rail side, once run into the larger rail gap of width, end of rail by crash protection cover, instead of directly clashes into wheel body 2, serves protective effect to wheel body 2.
Axle 5 bottom along rail to symmetrical both sides be provided with stop pin 4, prevent in the process of walking axle 5 perpendicular to rail to rotation.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model manual to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
