Description
Technical field
The present invention relates to railway construction, orbital mechanics and car track coupling dynamics testing field, specifically rail
The foil gauge fast accurate location and installation of wheel rail force test.
Background technique
The positioning of wheel track stress-strain piece relies primarily on the light instruments such as ruler pencil and carries out craft calmly under experiment condition at present
Position, since the foil gauge of test wheel rail force is higher to position accuracy demand, and hand paste needs to be measured distance with ruler, draws
Paste position and etc., inevitable appearance position error, causes final testing result inaccurate, designs in this context in the process
This wheel rail force foil gauge fast accurate positioning device is gone out.
Traditional strain gauge adhesion process sticking efficiency is low, and complex steps, precision is lower, for the precise positioning of foil gauge
Stickup has no special design.Therefore, conventional procedure needs to expend more manpowers and time, and obtained test result is but not
It is certain accurate.
The present invention is aiming at this problem to the fast accurate Position Design of wheel rail force foil gauge special device.Thus energy
Guarantee foil gauge it is quick, be efficiently and accurately pasted on rail, to improve measuring accuracy, reduce the working time.
Summary of the invention
Present invention seek to address that position precision present in existing wheel rail force strain gauge adhesion technology is low, sticking efficiency is low
The problem of.
The specific technical solution of the present invention is as follows:
A kind of wheel rail force foil gauge fast accurate positioning device, for accurately being determined on wheel track in wheel track research experiment
The setting position of foil gauge.By two pieces of scaling boards of mirror symmetry, i.e., left scaling board and right scaling board are constituted, are demarcated positioning device
Plate have with by the consistent contour structures of the web of the rail of experiment wheel track and rail bottom, scaling board and the tested wheel track web of the rail and rail bottom item
Corresponding position is provided with calibration hole；Pair correctly placed for observing positioning realization scaling board is provided in the middle part of scaling board bottom surface
Mesoporous；The snap device for realizing the connection of two scaling boards is provided at the top of left scaling board and right scaling board.
The antiskid rubber for avoiding positioning device from generating sliding along wheel track is provided on the inside of the scaling board.
The snap device is plane buckle: left scaling board has wedge mouth；Right scaling board, which has to be formed with wedge mouth, to be engaged
Wedge head.
Setting-out notch is provided on the calibration hole.
Scaling board is made by rigid plastics.
Snap device is located at right above rail head, in actual use, the present apparatus is placed on the rail for needing to demarcate, is passed through
Centring hole is found between two fasteners behind center, draws posting along calibration hole profile, draws foil gauge position along setting-out notch
Line removes device after complete, accurately paste position instruction is left on wheel track.
It is designed using the present invention, calibration hole is accurately positioned, accomplish that stickup rail foil gauge is quick and convenient, position is accurate,
To improve working efficiency and test result precision.By the above measure, without manual ranging, setting-out when pasting foil gauge, directly
The positioning setting-out of calibration hole was connected, foil gauge is pasted, has reached accurate positioning, pasted the effect of simple and fast.
Detailed description of the invention
Detailed description of the invention is as follows:
Fig. 1 is installation effect axonometric drawing of the invention.
Fig. 2 is vertical cross-sectional of the invention.
Specific embodiment:
Structure of the invention is described in further detail with reference to the accompanying drawing.
By can be seen in the figure, two piece scaling boards of the positioning device by mirror symmetry, i.e., left scaling board 10 and right scaling board 20
It constitutes.Scaling board have with by the consistent contour structures of the web of the rail of experiment wheel track 00 and rail bottom.Scaling board and tested wheel track
The web of the rail and rail bottom item corresponding position are provided with calibration hole, such as 11 and 21, and calibration hole can be arranged in many places as needed.
The centring hole 13 correctly placed for observing positioning realization scaling board is provided in the middle part of scaling board bottom surface.Left calibration
The top of plate 10 and right scaling board 20 is provided with the snap device 30 for realizing the connection of two scaling boards.When experiment installation as shown in Figure 1,
Engaging is surrounded in rail or so.
The antiskid rubber for avoiding positioning device from generating sliding along wheel track is provided on the inside of scaling board.Antiskid rubber can be used certainly
Viscous rubber strip sticks at caliberating device plate corresponding position, the side print of antiskid rubber and rail contact as shown in figure 22 and 23
Anti-skid chequer processed reaches increase resistance, prevents the purpose that opposite sliding occurs with rail.
In actual implementation, snap device 30 can be by diversified forms, and snap device 30 is plane card in figure embodiment
Button, left scaling board 10 have wedge mouth 15；Right scaling board 20, which has, forms the wedge head 25 engaged with wedge mouth 15.
Setting-out notch 12 is provided on the calibration hole 11, in order to the operation that draws lines.
By the above measure, working efficiency can be improved to avoid not accurately unarmed operation when pasting wheel rail force foil gauge.
