Abstract
The utility model relates to a kind of high speed railway track measuring instrument directive wheel and road wheel combining structure.The connection arrangement relation of rail measuring apparatus road wheel and directive wheel directly determines integrally-built compactness and namely to walk fluency.The utility model comprises road wheel and directive wheel, and road wheel is installed on road wheel wheel shaft, and directive wheel is installed on directive wheel wheel shaft, and directive wheel wheel shaft is vertically fixed on road wheel wheel shaft; Part straight rail in road wheel wheel shaft is stretched into being symmetrically arranged with a pair stop pin in directive wheel wheel shaft bottom.The wheel shaft of directive wheel and the wheel shaft of road wheel are placed in and are same as in plane by the utility model, make more compact structure, make road wheel and directive wheel interfix, decrease the quantity of directive wheel, improve the fluency of walking, enhance the guide effect of directive wheel.
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 directive wheel and road wheel combining structure.
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 directive wheel, road wheel walks in rail head track face, in rail side, walking play the guiding role directive wheel, and the connection arrangement relation between two-wheeled directly determines integrally-built compactness and walking fluency.
Summary of the invention
The purpose of this utility model is to provide a kind of high speed railway track measuring instrument directive wheel and road wheel combining structure, promotes walking fluency.
The technical scheme that the utility model adopts is:
A kind of high speed railway track measuring instrument directive wheel and road wheel combining structure, comprise road wheel and directive wheel, it is characterized in that:
Road wheel is installed on road wheel wheel shaft, and directive wheel is installed on directive wheel wheel shaft, and directive wheel wheel shaft is vertically fixed on road wheel wheel shaft;
Part straight rail in road wheel wheel shaft is stretched into being symmetrically arranged with a pair stop pin in directive wheel wheel shaft bottom.
The axial both sides of directive wheel wheel shaft are provided with symmetrical, L-shaped directive wheel wheel shaft axle sleeve, coated whole directive wheel wheel shaft, directive wheel wheel shaft axle sleeve top is positioned at directive wheel side, and directive wheel opposite side is provided with directive wheel wheel cover plate, and directive wheel 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.
Directive wheel wheel shaft monosymmetric directive wheel wheel shaft axle sleeve is by fixing through the set bolt of directive wheel wheel shaft.
The utility model has the following advantages:
The wheel shaft of directive wheel and the wheel shaft of road wheel are placed in same plane by the utility model, make more compact structure, in limited space, rational layout and tissue are carried out to assembly, achieve multi-functional integrated in the confined space, road wheel and directive wheel interfix, decrease the quantity of directive wheel, improve the fluency of walking, enhance the guide effect of directive wheel.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model structure chart (the additional nylon protective sleeve of directive wheel).
In figure, 1-directive wheel, 2-road wheel, 3-directive wheel wheel shaft, 4-road wheel wheel shaft, 5-stop pin, 6-directive wheel wheel cover plate, 7-set bolt, 8-directive wheel wheel shaft axle sleeve.
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 directive wheel that the utility model relates to and road wheel combining structure, comprise road wheel 2 and directive wheel 1, road wheel 2 is installed on road wheel wheel shaft 4, directive wheel 1 is installed on directive wheel wheel shaft 3, directive wheel wheel shaft 3 is vertically fixed on road wheel wheel shaft 4, and directive wheel wheel shaft 3 and road wheel wheel shaft 4 consolidation are integrated and are positioned at same perpendicular.Part straight rail in road wheel wheel shaft 4 is stretched into being symmetrically arranged with a pair stop pin 5 in directive wheel wheel shaft 3 bottom, prevents directive wheel wheel shaft 3 from rotating, therefore can arrange multiple directive wheel in road wheel wheel shaft 4 both sides and carry out spacing.
The axial both sides of directive wheel wheel shaft 3 are provided with symmetrical, L-shaped directive wheel wheel shaft axle sleeve 8, coated whole directive wheel wheel shaft 3, directive wheel wheel shaft axle sleeve 8 top is positioned at directive wheel 1 side, directive wheel 1 opposite side is provided with directive wheel wheel cover plate 6, and directive wheel wheel cover plate 6 passes through bolt consolidation with axle sleeve 3 top.Wheel body 2 diameter is greater than the width at wheel cover plate 1 and axle sleeve 3 top.Directive wheel wheel shaft 3 monosymmetric directive wheel wheel shaft axle sleeve 8 is fixed by the set bolt 7 through directive wheel wheel shaft 3.Directive wheel wheel shaft axle sleeve 8 and directive wheel wheel cover plate 6 adopt nylon material, avoid the safety that the wheel shaft generation electric impact of metal material is measured.
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.
