Description
Technical field
The utility model relates to railway construction, orbital mechanics and car track coupling dynamics field tests, is the foil gauge fast accurate location and installation of rail wheel rail force test specifically.
Background technology
Under current experiment condition, the location of wheel track stress-strain sheet mainly relies on the light instruments such as ruler pencil to carry out manual location, because the foil gauge testing wheel rail force is higher to position accuracy demand, and hand paste needs to use ruler measuring distance, draw the steps such as paste position, there is site error unavoidably in the process, cause final testing result to be forbidden, have devised this wheel rail force foil gauge fast accurate locating device in this context.
Tradition strain gauge adhesion process sticking efficiency is low, complex steps, and precision is lower, and the precise positioning for foil gauge is pasted and be there is no special design.Therefore, conventional procedure needs to expend more manpower and time, and the test result obtained but might not be accurate.
The utility model be exactly for this problem to the fast accurate Position Design of wheel rail force foil gauge special device.Thus can ensure foil gauge quick, be pasted onto on rail efficiently and accurately, thus improve measuring accuracy, reduce the working time.
The content of utility model
The utility model is intended to solve the problem that positional precision is low, sticking efficiency is low existed in existing wheel rail force strain gauge adhesion technology.
Concrete technical scheme of the present utility model is as follows:
A kind of wheel rail force foil gauge fast accurate locating device, for accurately determining the setting position of foil gauge in wheel track research experiment on wheel track.Locating device is by two pieces of scaling boards of specular, namely left scaling board 10 and right scaling board 20 are formed, scaling board have with by the consistent contour structures of the web of the rail and the flange of rail of testing wheel track, scaling board and the tested wheel track web of the rail and flange of rail item correspondence position are provided with demarcates hole; The middle part of scaling board bottom surface is provided with the centring hole 13 of correctly laying for observing location realize scaling board; The top of left scaling board 10 and right scaling board 20 is provided with the snap device 30 realizing two scaling boards and connect.
Snap device is positioned at directly over rail head, during actual use, this device is placed on the rail of needs demarcation, to find between two fasteners behind center by centring hole, posting is drawn along demarcating hole profile, draw the foil gauge position line along setting-out notch, after complete, take off device, wheel track leaves paste position instruction accurately.
Employing the utility model designs, and accurately locates demarcation hole, and accomplish to paste rail foil gauge quick and convenient, position is accurate, thus increases work efficiency and test result precision.By above measure, without the need to manual range finding, setting-out during stickup foil gauge, directly by demarcating hole location setting-out, pasting foil gauge, reaching accurate location, the effect of stickup simple and fast.
Accompanying drawing is described as follows:
Fig. 1 is installation effect axonometric drawing of the present utility model.
Fig. 2 is vertical cross-sectional of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, structure of the present utility model is described in further detail.
Can see by figure, locating device is by two pieces of scaling boards of specular, and namely left scaling board 10 and right scaling board 20 are formed.Scaling board have with by the consistent contour structures of the web of the rail and the flange of rail of testing wheel track 00.Scaling board and the tested wheel track web of the rail and flange of rail item correspondence position are provided with demarcates hole, and as 11 and 21, demarcating hole can be arranged in many places as required.The middle part of scaling board bottom surface is provided with the centring hole 13 of correctly laying for observing location realize scaling board.The top of left scaling board 10 and right scaling board 20 is provided with the snap device 30 realizing two scaling boards and connect.Press shown in Fig. 1 when experiment is installed, surround about rail and engage.
Be provided with inside scaling board and avoid locating device to produce the antiskid glue cushion of slippage along wheel track.Antiskid glue cushion can adopt self-adhering rubber bar, as shown in 22 and 23 in figure, sticks at caliberating device plate relevant position, and the side that antiskid glue cushion contacts with rail prints anti-slip veins, reaches increase resistance, prevents the object with rail generation relative sliding.
In reality is implemented, snap device 30 can by various ways, and in accompanying drawing embodiment, snap device 30 is plane buckle, and left scaling board 10 has wedge mouth 15; Right scaling board 20 has and forms with wedge mouth 15 the wedge head 25 engaged.
Described demarcation hole 11 is provided with setting-out notch 12, so that setting-out operation.
By above measure, free-hand operation accurately can be avoided not when pasting wheel rail force foil gauge, increase work efficiency.
