Abstract
The invention relates to a brake structure for a traveling wheel of a high-speed railway track measurement instrument. The traveling wheel of the track measurement instrument travels on a top rail face of a steel rail and a corresponding brake structure is required when the traveling wheel is stopped or the track measurement instrument is required to stand. According to the brake structure, a barrel-shaped shaft sleeve which is in parallel to a wheel shaft of the traveling wheel is arranged above the wheel face of the traveling wheel; an arc brake slice adaptive to the shape of the wheel face of the traveling wheel is fixed at the bottom end of the shaft sleeve; a brake shaft is arranged in the shaft sleeve; an eccentric shaft which is in parallel to the axial direction of the brake shaft is arranged at the middle part of the brake shaft, and the diameter of the eccentric shaft is greater than that of the brake shaft; a brake rod perpendicular to the brake shaft is arranged at the end part of the brake shaft. According to the design of the brake structure, the brake slice and the brake shaft with the eccentric structure are arranged; effective braking of the traveling wheel can be completed by the simple mechanical action; the brake structure has a simple structure and is convenient to operate.
Description
Technical field
the invention belongs to railroad survey technical field, be specifically related to a kind of high speed railway track measuring instrument road wheel brake 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, the detection for railroad track smooth degree adopts the mode of track geometry status measuring instrument to carry out more, i.e. rail measuring apparatus, and the road wheel of this instrument walks in rail head track face, needs corresponding skidding structure when stopping or needing rail measuring apparatus to leave standstill.
Summary of the invention
The object of this invention is to provide a kind of high speed railway track measuring instrument road wheel brake structure, road wheel is effectively braked.
The technical solution adopted in the present invention is:
High speed railway track measuring instrument road wheel brake structure, is characterized in that:
Above road wheel wheel face, arrange tubular axle sleeve parallel with road wheel wheel shaft, axle sleeve bottom is fixed with the brake holding sheet adapted in cambered surface with road wheel wheel face shape, is provided with brake axle in axle sleeve;
The eccentric shaft that and diameter axially parallel with brake axle is greater than brake axle is provided with in the middle part of brake axle;
Brake axle end is provided with the brake bar vertical with brake axle.
Described brake holding sheet bottom surface is provided with two friction plates parallel with road wheel wheel shaft, lays respectively at the two ends of brake holding sheet.
Brake bar end is provided with installing sleeve, adds and is placed on brake axle end, and is fixed by the clamping bolt of sidewall.
The present invention has the following advantages:
The present invention devises brake holding sheet and has the brake axle of eccentric structure, completes the effective brake of road wheel by simple mechanical action, rational in infrastructure, easy to operate.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
Fig. 2 is brake axle structure chart.
In figure, 1-road wheel, 2-brake holding sheet, 3-axle sleeve, 4-brake axle, 5-brake bar, 6-directive wheel, 7-eccentric shaft.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
The present invention relates to a kind of high speed railway track measuring instrument road wheel brake structure, above road wheel 1 wheel face, tubular axle sleeve 3 parallel with road wheel wheel shaft is set, axle sleeve 3 bottom is fixed with the brake holding sheet 2 adapted in cambered surface with road wheel 1 wheel face shape, brake holding sheet 2 bottom surface is provided with two friction plates parallel with road wheel wheel shaft, lays respectively at the two ends of brake holding sheet 2.Be provided with brake axle 4 in axle sleeve 3, in the middle part of brake axle 4, be provided with the eccentric shaft 7 that and diameter axially parallel with brake axle 4 is greater than brake axle 4.Brake axle 4 end is provided with the brake bar 5 vertical with brake axle 4.Brake bar 5 end is provided with installing sleeve, adds and is placed on brake axle 4 end, and fixed by the clamping bolt of sidewall.
When needing to brake road wheel 1, pull brake bar 5 downwards, brake axle 4 is driven to rotate, and under the effect of eccentric shaft 7, brake holding sheet 2 moves down and compresses road wheel 1 wheel face, realizes braking.
Content of the present invention is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading manual of the present invention to any equivalence that technical solution of the present invention is taked, is claim of the present invention and contains.
