Abstract
The present invention relates to a kind of high speed railway track measuring instrument road wheel brake structure.The road wheel of rail measuring apparatus walks in rail head track face, stops or needing rail measuring apparatus to need corresponding skidding structure when standing.The present invention is provided above tubular axle sleeve parallel with road wheel wheel shaft in road wheel wheel face, and axle sleeve bottom is fixed with and adapts the brake holding sheet in cambered surface with road wheel wheel face shape, is provided with brake axle in axle sleeve；And diameter axially in parallel with the brake axle eccentric shaft more than brake axle it is provided with in the middle part of brake axle；Brake axle end is provided with the brake bar vertical with brake axle.The present invention devises brake holding sheet and has the brake axle of eccentric structure, can be completed the effective brake of road wheel by simple mechanical action, rational in infrastructure, easy 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 orbit for a long time due to train and the change of track bed, and the height making track occur rises and falls and left and right offsets, and affects the normal traveling of train.Along with improving constantly of train running speed, for realizing safety and the comfortableness of train operation, the particularly 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, railway irregularity state parameter is required more and more higher by railroad, and therefore the detection to rail smooth degree particularly seems important with safeguarding.
The detection mode using track geometry status measuring instrument currently for railroad track smooth degree carries out more, i.e. rail measuring apparatus, the road wheel of this instrument walks in rail head track face, stops or needing rail measuring apparatus to need corresponding skidding structure when standing.
Summary of the invention
It is an object of the invention 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, it is characterised in that:
Being provided above tubular axle sleeve parallel with road wheel wheel shaft in road wheel wheel face, axle sleeve bottom is fixed with and adapts the brake holding sheet in cambered surface with road wheel wheel face shape, is provided with brake axle in axle sleeve；
And diameter axially in parallel with the brake axle eccentric shaft more than brake axle it 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 parallel with road wheel wheel shaft friction plate, lays respectively at the two ends of brake holding sheet.
Brake bar end is provided with installation sleeve, adds and is placed on brake axle end, and is fixed by the clamping bolt of sidewall.
The invention have the advantages that
The present invention devises brake holding sheet and has the brake axle of eccentric structure, can be completed the effective brake of road wheel by simple mechanical action, rational in infrastructure, easy to operate.
Accompanying drawing explanation
Fig. 1 is present configuration figure.
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, it is provided above tubular axle sleeve 3 parallel with road wheel wheel shaft in road wheel 1 wheel face, axle sleeve 3 bottom is fixed with and adapts the brake holding sheet 2 in cambered surface with road wheel 1 wheel face shape, brake holding sheet 2 bottom surface is provided with two parallel with road wheel wheel shaft friction plate, lays respectively at the two ends of brake holding sheet 2.Axle sleeve 3 is provided with brake axle 4, in the middle part of brake axle 4, is provided with and diameter axially in parallel with brake axle 4 eccentric shaft 7 more 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 installation sleeve, adds and is placed on brake axle 4 end, and is fixed by the clamping bolt of sidewall.
When needing to be braked road wheel 1, pulling downwards brake bar 5, brake axle 4 is driven to rotate, and under the effect of eccentric shaft 7, brake holding sheet 2 moves down compression road wheel 1 wheel face, it is achieved braking.
Present disclosure is not limited to cited by embodiment, and the conversion of any equivalence that technical solution of the present invention is taked by those of ordinary skill in the art by reading description of the invention, the claim being the present invention is contained.
