With reference to fig. 1 to 3, an embodiment of the present invention provides a coupling height difference measuring apparatus, including a measuring mechanism 1 and an angle measuring instrument 20, where the measuring mechanism 1 includes a measuring plate 10 and a first bridging plate 110 and a second bridging plate 120 disposed on opposite sides of the measuring plate 10, so that the measuring plate 10 is in a horizontal state when the measuring plate 10 is disposed on a horizontal plane, and the first bridging plate 110 and the second bridging plate 120 are adapted to be disposed across a traction motor shaft 30 and a gearbox shaft 40, respectively; the angle measuring instrument 20 is provided on the measuring plate 10 and adapted to show 0 degree when the measuring plate 10 is in a horizontal state, and the angle measuring instrument 20 is used to measure an angle between the measuring plate 10 and a horizontal plane with respect to an inclined plane formed between the traction motor shaft 30 and the gearbox shaft 40 to obtain a height difference between the axial center of the traction motor shaft 30 and the axial center of the gearbox shaft 40.
It should be noted that, the first bridging plate 110 and the second bridging plate 120 are respectively bridged over the traction motor shaft 30 and the gearbox shaft 40, the horizontal inclination angle of the measurement plate 10 can be measured by the angle measuring instrument 20, the inclination angle is consistent with the inclination angle between the axis of the traction motor shaft 30 and the axis of the gearbox shaft 40, and the height difference between the axis of the traction motor shaft 30 and the axis of the gearbox shaft 40 can be obtained by measuring the distance between the axis of the traction motor shaft 30 and the axis of the gearbox shaft 40 by using a ruler, the measurement tool is simple, the surfaces of the traction motor shaft 30 and the gearbox shaft 40 do not need to be processed, the structural strength of the traction motor shaft 30 and the gearbox shaft 40 is prevented from being affected, the measurement by an operator is facilitated, and the coupling for measuring the height difference is improved.
In some embodiments of the present invention, measurement plate 10 includes oppositely disposed first and second mounting surfaces 130 and 140; the first cross plate 110 and the second cross plate 120 are mounted on the first mounting surface 130 and extend away from the first mounting surface 130; the angle measuring instrument 20 is provided on the second mounting surface 140.
That is, the angle measuring instrument 20 is located on a side of the measuring plate 10 away from the first cross plate 110 and the second cross plate 120, and when the first cross plate 110 and the second cross plate 120 are respectively bridged to the traction motor shaft 30 and the gearbox shaft 40, an inclination angle of the second mounting surface 140 is identical to an inclination angle between a center of the traction motor shaft 30 and a center of the gearbox shaft 40.
The distance between the center of the traction motor shaft 30 and the center of the gearbox shaft 40 can be quickly obtained through a ruler, and when the angle measuring instrument 20 measures the inclination angle of the measuring plate 10, the height difference between the center of the traction motor shaft 30 and the center of the gearbox shaft 40 can be calculated according to a trigonometric function.
Preferably, the first cross plate 110 and the second cross plate 120 are symmetrically arranged along the center line of the survey plate 10, and the lengths of the first cross plate 110 and the second cross plate 120 extend for a uniform distance.
That is, in order to avoid the accuracy of the measurement of the inclination angle of the measurement plate 10 by the first bridging plate 110 and the second bridging plate 120, the first bridging plate 110 and the second bridging plate 120 are symmetrically arranged, so that the inclination angle of the measurement plate 10 is consistent with the inclination angle between the axis of the traction motor shaft 30 and the axis of the gearbox shaft 40, and the influence on the inclination angle measurement caused by the structure or weight of the first bridging plate 110 and the second bridging plate 120 is avoided.
For example, if the first cross plate 110 and the second cross plate 120 are arranged asymmetrically, the tilt angle of the measurement plate 10 is affected by the weight of the first cross plate 110 and the second cross plate 120, which makes the measurement process complicated.
Referring to fig. 2, in some embodiments of the present invention, the first cross plate 110 and the second cross plate 120 each include a first cross leg 150 and a second cross leg 160; the first and second bridging legs 150 and 160 are oppositely disposed in the transverse direction of the measuring board 10 and straddle the outer surfaces of the traction motor shaft 30 and the gear box shaft 40.
The first bridging leg 150 and the second bridging leg 160 are provided to support the measuring board 10, so as to prevent the measuring board 10 from tilting during the measuring process and affecting the measuring accuracy.
Preferably, the ends of the first bridging leg 150 and the second bridging leg 160 away from the measuring board 10 are set to be concave cambered surfaces for fitting the outer surfaces of the traction motor shaft 30 and the gearbox shaft 40, so as to improve the placing stability of the measuring board 10 on the traction motor shaft 30 and the gearbox shaft 40 and avoid the measuring board 10 from being inclined to influence the measuring precision thereof in the measuring process.
That is, the arc-shaped end portions of the first bridging leg 150 and the second bridging leg 160 are more favorable for being attached to the outer surfaces of the traction motor shaft 30 and the gearbox shaft 40, so that the measurement plate 10 is less influenced by the outside in the measurement process, and the accuracy of angle measurement of the measurement plate 10 is improved.
Referring to fig. 3, in still other embodiments of the present invention, the first cross plate 110 and the second cross plate 120 are disposed across the outer end surfaces of the traction motor shaft 30 and the gearbox shaft 40; the first bridge plate 110 and the second bridge plate 120 enclose a measurement space 170 therebetween, and the measurement plate 10 abuts against the outer end surfaces of the traction motor shaft 30 and the gear box shaft 40, respectively, at the inner side wall of the measurement space 170.
That is, the first and second bridge plates 110 and 120 do not abut against the traction motor shaft 30 and the gear box shaft 40, but support and abut against the outer surfaces of the traction motor shaft 30 and the gear box shaft 40 at the bottom surface of the measurement plate 10 facing the measurement space 170, so that the angle between the axial centers of the traction motor shaft 30 and the gear box shaft 40 is measured.
Referring specifically to fig. 3, the angle of the tilt angle of the measurement plate 10 is the same as the angle E, and as shown, the angle E is the same as the angle D.
That is, the angle detected by the angle measuring instrument 20 is coincident with the inclination between the axial center of the traction motor shaft 30 and the axial center of the gear box shaft 40. The distance between the axis of the traction motor shaft 30 and the axis of the gearbox shaft 40 can be obtained by a ruler, for example, the ruler measures the distance between the traction motor shaft 30 and the gearbox shaft 40 plus the distance L between the axes of the traction motor shaft 30 and the gearbox shaft 40 and the end faces of each other, that is, the distance O2 between the axis O1 of the traction motor shaft 30 and the axis of the gearbox shaft 40 is known. After the angle D is also measured, the height difference between the axes of the traction motor shaft 30 and the gearbox shaft 40 can be calculated according to the trigonometric function. That is, the spacing C between AB can be calculated.
I.e. C = ARCTAN (D °) L.
That is, when the distance between the axles AB needs to be measured, only the first bridging plate 110 and the second bridging plate 120 need to be bridged to the outer sides of the traction motor shaft 30 and the gearbox shaft 40, and the height difference between the traction motor shaft 30 and the gearbox shaft 40 can be quickly obtained through calculation, so that the measurement mode is simpler, the structures of the traction motor shaft 30 and the gearbox shaft 40 do not need to be improved, and the measured result is more accurate.
Specifically, the first jumper plate 110 and the second jumper plate 120 respectively include a first plate body 180 and a second plate body 190 connected to the first plate body 180; an avoidance space 1810 is formed between the two first plate bodies 180 of the first cross plate 110 and the second cross plate 120, and is used for avoiding the connecting piece of the traction motor shaft 30 and the gearbox shaft 40; the second plate body 190 and the first plate body 180 are arranged at an included angle and extend towards a direction deviating from the avoiding space 1810, and the two second plate bodies 190 are respectively abutted to the outer surfaces of the traction motor shaft 30 and the gear box shaft 40.
The second plate 190 is perpendicular to the first plate 180, and an avoiding space 1810 formed between the first plate 180 can avoid a connecting member, a bolt used for mounting, and the like between the traction motor shaft 30 and the gearbox shaft 40. Therefore, the second plate 190 can be attached to the outer wall surfaces of the traction motor shaft 30 and the gearbox shaft 40, and the inclination angle of the measuring plate 10 is convenient for the included angle between the axis of the traction motor shaft 30 and the axis of the gearbox shaft 40 to be consistent.
Further, a third plate body 1910 is further arranged in the direction of the second plate body 190 away from the first plate body 180, and an included angle between the third plate body 1910 and the second plate body 190 is set; a bridging space 1920 is formed between the two third plate bodies 1910 of the first bridging plate 110 and the second bridging plate 120, and the bridging space 1920 is used for avoiding the traction motor shaft 30 and the gearbox shaft 40.
The third plate 1910 is perpendicular to the second plate 190, and the bridging space 1920 is formed to prevent the measuring plate 10 from falling off when the inclination angles of the traction motor shaft 30 and the gearbox shaft 40 are too large, so as to ensure the normal measuring operation.
In some embodiments of the invention, the angle measuring instrument 20 is an electronic angle gauge. Therefore, the invention does not need to knock scale marks on the traction motor shaft 30 or the gearbox shaft 40, thereby avoiding influencing the structural strength of the traction motor shaft 30 and the gearbox shaft 40, improving the measurement precision of the height difference angle of the bogie coupling, and ensuring that the operation space is more abundant.
With respect to the first cross plate 110 and the second cross plate 120, in the embodiment of the present invention, the first cross plate 110 and the second cross plate 120 are provided integrally with the measuring plate 10. It should be noted that, in some other embodiments, the first cross plate 110 and the second cross plate 120 may also be detachably disposed on the measurement plate 10, for example, the first cross plate and the second cross plate are connected to the measurement plate 10 by a detachable connection member such as a bolt, and the specific other detachable manner is not limited herein.
Referring to fig. 4, an embodiment of the present invention further provides a method for measuring a height difference of a coupling, including:
s110: the angle measuring instrument is calibrated so that the angle measuring instrument displays 0 degree when the measuring plate is kept in a horizontal state.

That is, for the height difference between the traction motor shaft and the gearbox shaft, the distance from the shaft center of the traction motor shaft to the shaft center of the gearbox shaft may be obtained first, for example, through a ruler or data obtained in advance, and then the included angle from the shaft center of the traction motor shaft to the shaft center of the gearbox shaft relative to the horizontal plane may be obtained through an angle measuring instrument. Because the included angle of the measuring plate relative to the horizontal plane is consistent with the included angle of the axis of the traction motor shaft and the axis of the gear box shaft relative to the horizontal plane.
