Description
Technical field
The invention belongs to railroad survey technical field, be specifically related to a kind of rail measuring apparatus and measure the parallel connecting structure of wheel and displacement transducer.
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.
At present, the mode using track geometry status measuring instrument is detected more for railroad track smooth degree carry out, i.e. rail measuring apparatus, measurement wheel it is provided with inside the road wheel at these instrument crossbeam two ends, measure gauge or rail to vector distance, measure wheel be perpendicular to rail to displacement displacement transducer pass through obtain, measure wheel and the space layout of displacement transducer directly affect accuracy and the reliability of data acquisition, also affect compactness and the reasonability of Integral cross beam structure.
Summary of the invention
It is an object of the invention to provide a kind of rail measuring apparatus and measure the parallel connecting structure of wheel and displacement transducer, the locus measuring wheel and displacement transducer is carried out rational deployment.
The technical solution adopted in the present invention is:
Rail measuring apparatus measures the parallel connecting structure of wheel and displacement transducer, including measuring wheel and displacement transducer, it is characterised in that:
The installation base plate of a few font of opening upwards is set in beam-end bottom surface, installation base plate bottom surface be provided perpendicular to rail to guide rail, guide rail is provided with guide rail slide block, measures wheel by measuring wheel wheel shaft and be fixed on guide rail slide block bottom surface；
Displacement transducer is placed in the groove of a few font installation base plate, and displacement transducer is connected by the connecting plate of L-shaped with guide rail slide block.
Crossbeam inwall is fixed on by connecting rod in the end of displacement transducer.
The invention have the advantages that
The present invention is fixed on measuring wheel on the slide block of guide rail, slide block and displacement transducer are respectively arranged in the both sides up and down of installation base plate again, form the parallel join relation being distributed up and down, achieve measurement wheel and displacement transducer rational deployment on locus, improve crossbeam and arrange the compactness of structure, it is ensured that the accuracy of displacement sensor result and reliability.

Fig. 2 is present configuration figure (pumping installation base plate).
In figure, 1-measures wheel, and 2-measures wheel wheel shaft, 3-guide rail slide block, 4-guide rail, 5-connecting rod, 6-connecting plate, 7-displacement transducer, 8-installation base plate.
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 rail measuring apparatus and measure the parallel connecting structure of wheel and displacement transducer, the installation base plate 8 of a few font of opening upwards is set in beam-end bottom surface, installation base plate 8 bottom surface be provided perpendicular to rail to guide rail 4, guide rail 4 is provided with guide rail slide block 3, measures wheel 1 by measuring wheel wheel shaft 2 and be fixed on guide rail slide block 3 bottom surface.Displacement transducer 7 is placed in the groove of a few font installation base plate 8, and displacement transducer 7 is connected by the connecting plate 6 of L-shaped with guide rail slide block 3.Measure wheel 1, guide rail 4 and guide rail slide block 3 and lay respectively at installation base plate about 8 both sides with displacement transducer 7, form the parallel connecting structure being distributed up and down.Crossbeam inwall is fixed on by connecting rod 5 in the end of displacement transducer 7.
In rail measuring apparatus walking process, measure wheel 1 can produce be perpendicular to rail to displacement, drive guide rail slide block 3 is perpendicular to rail in guide rail 4 to slip, thus draws displacement transducer 7 and measure.
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.
