Abstract
The utility model relates to a kind of high speed railway track measuring instrument meter wheel and road wheel combining structure.Connection arrangement relation between rail measuring apparatus meter wheel and road wheel directly determines integrally-built compactness and fluency of walking.The utility model comprises road wheel and meter wheel, and road wheel is installed on road wheel wheel shaft, and meter wheel is installed on meter wheel wheel shaft, road wheel wheel shaft and the orthogonal two adjacent surfaces being installed on the piston contiguous block of rectangle of meter wheel wheel shaft; Piston contiguous block is connected with piston rod relative to the offside of road wheel, and upper cover of piston rod has piston bush.The wheel shaft of meter wheel and the wheel shaft of road wheel are placed in same plane by the utility model, make more compact structure, road wheel and meter wheel interfix, meter wheel with piston rod perpendicular to rail to generation displacement, the parameters such as gauge are measured and mobile phone, the fluency of walking improves, and measurement result is more reliable.
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 meter 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 meter wheel, for detecting the parameter relevant with orbital forcing such as gauge, the connection arrangement relation between meter wheel and road wheel 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 meter wheel and road wheel combining structure, ensures walking fluency, improves the measurement accuracy of meter wheel.
The technical scheme that the utility model adopts is:
A kind of high speed railway track measuring instrument meter wheel and road wheel combining structure, comprise road wheel and meter wheel, it is characterized in that:
Road wheel is installed on road wheel wheel shaft, and meter wheel is installed on meter wheel wheel shaft, road wheel wheel shaft and the orthogonal two adjacent surfaces being installed on the piston contiguous block of rectangle of meter wheel wheel shaft;
Piston contiguous block is connected with piston rod relative to the offside of road wheel, and upper cover of piston rod has piston bush.
Piston contiguous block bottom surface is provided with fluting, and road wheel wheel shaft penetrates in groove sideways through axis hole, outside road wheel wheel shaft, is provided with road wheel wheel bearing in axis hole;
Road wheel axle ends is connected with the odometer being placed in piston contiguous block bottom surface fluting.
Odometer is fixed on the bottom surface fluting of piston contiguous block by the trunnion base of U-shaped.
The utility model has the following advantages:
The wheel shaft of meter 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 meter wheel interfix, meter wheel with piston rod perpendicular to rail to generation displacement, the parameters such as gauge are measured and mobile phone, the fluency of walking improves, and measurement result is more reliable.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
Fig. 2 is that road wheel and road wheel take turns Axile connection structure figure.
In figure, 1-road wheel, 2-meter wheel, 3-road wheel wheel shaft, 4-trunnion base, 5-odometer, 6-piston contiguous block, 7-piston bush, 8-piston rod, 9-meter wheel wheel shaft, 10-road wheel wheel bearing.
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 meter wheel that the utility model relates to and road wheel combining structure, comprise road wheel 1 and meter wheel 2, road wheel 1 is installed on road wheel wheel shaft 3, meter wheel 2 is installed on meter wheel wheel shaft 9, road wheel wheel shaft 3 and the orthogonal two adjacent surfaces being installed on the piston contiguous block 6 of rectangle of meter wheel wheel shaft 9.Piston contiguous block 6 is connected with piston rod 8 relative to the offside of road wheel 1, and on piston rod 8, cover has piston bush 7.
Piston contiguous block 6 bottom surface is provided with fluting, and road wheel wheel shaft 3 penetrates in groove sideways through axis hole, outside road wheel wheel shaft 3, is provided with road wheel wheel bearing 10 in axis hole; Road wheel wheel shaft 3 end is connected with the odometer 5 being placed in piston contiguous block 6 bottom surface fluting.Odometer 5 is fixed on the bottom surface fluting of piston contiguous block 6 by the trunnion base of U-shaped.
During walking, due to the setting of piston rod 8 and piston bush 7, make piston contiguous block 6 can drive meter wheel 2 together perpendicular to rail to displacement, odometer 5 can record the walking mileage of road wheel 1.
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.
