The specific embodiment
Below in conjunction with accompanying drawing and specific embodiments the utility model is further described.
Embodiment 1: like Fig. 1～shown in Figure 3; A kind of screen scarifier that is provided with accurate measurement excavation depth device comprises the control device that is provided with microprocessor, excavating gear and respectively as the left and right guide groove that promotes guide groove and decline guide groove; Left side guide groove 1 and right guide groove 2 are respectively equipped with two oil cylinders of controlling level direction position and vertical direction position; On screen scarifier, be provided with three angular transducers, wherein, the angular transducer 1 of measurement of left guide groove gradient is installed in the right flank of left guide groove 1; Measure the left surface that right guide groove gradient angular transducer 2 21 is installed in right guide groove 2; The angular transducer 3 31 of measuring the track inclination in the running direction is installed on the car body 3 through flat board is installed, and the output of all angles sensor is connected with the microprocessor input of said control device respectively, and microprocessor has output to be connected with display unit.Guide rail 4 and sleeper 41 are shown among the figure simultaneously.
Car body be provided with install dull and stereotyped 32, install dull and stereotyped 32 be provided with tilt adjusting apparatus and with the corresponding screw of the installing hole of angular transducer.The upper surface of mounting plane can satisfy the requirement to reference for installation through fine finishining, the reference for installation of tilt adjusting apparatus adjustment angular transducer.
Angular transducer is used capacitance type angle sensor; That such angular transducer has is simple in structure, highly sensitive, resolving power is high, the advantage of adverse environment resistant.
The outside of angular transducer is provided with protective cover.Add protective cover can avoid angular transducer at operation field because of the ambient conditions difference or collide accidentally and be damaged.
Measuring principle is described below.
Shown in Figure 2 promptly do not have the metering system under the gradient state for rail is in level:
Among the figure, α is horizontal initial angle; β is left and right guide groove actual angle measurement; H is left and right guide groove height; L is left and right guide groove length; H is an excavation depth; Wherein α, H, L are given value.
The excavation depth design formulas:
h=L*Sin(α+β)-H （mm）
H=L*Sinα （mm）
So the excavation depth that rail is under the level does
h=L*Sin(α+β)-?L*Sinα (mm)
Fig. 3 is a metering system after the correction of the adding rail gradient.
Among Fig. 2～Fig. 3, α is horizontal initial angle; β is left and right guide groove actual angle measurement; H is left and right guide groove height; L is left and right guide groove length; H is an excavation depth; γ is that the rail longitudinal grade influences the angle to left and right guide groove; The lower outside distance of left and right guide groove is L3; Lateral extent is L4 outside the upper end of left and right guide groove; The distance of the lower outside mid point of left and right guide groove and the outside, upper end mid point is L5; Left and right guide groove decline rotational angle is θ; Left and right guide groove and horizontal plane angle are γ 1.
The excavation depth design formulas:
h=L*Sin(α+β-γ)-H （mm）
H=L*Sinα （mm）
Because measuring the angular transducer actual measured value at rail longitudinal grade angle is rail longitudinal grade angle, thus to convert the angle changing value of guide groove direction to, shown under Fig. 3
sinγ=sinγ1*L5/L
Because, L5=cos θ L
So, sin γ=sin γ 1*cos θ
So, cos θ=arcsin ((L3-L4)/2L)
Can draw thus
γ=arcsin[sinγ1*arcsin（(L3-L4)/2L）]
So the revised excavation depth of the adding rail gradient does
h=L*sin(α+β-arcsin[sinγ1*arcsin((L3-L4)/2L)])-L*Sinα（mm）
This numerical value is handled automatically by microprocessor and is shown that operating personnel adjust the relevant apparatus of screen scarifier according to the numerical value that is shown.
The utility model is used for the excavation depth adjustment of railway screen scarifier; Simple in structure, easy to adjust, clear display is accurate; Improve effect; If those skilled in the art does simple the modification or replacement to the foregoing invention content, such change can not think to break away from the scope of the utility model, and all will be included within the scope of claim of the utility model the conspicuous modification of those skilled in the art like this.
