Background
With the development of rail transit and the continuous acceleration of trains, the safety problem is also continuously highlighted. The wheel set is used as an important part of a bearing train, complex acting force from a train body and a steel rail needs to be borne when the rail transit vehicle runs at a high speed, and a rail line is often corroded by rainwater, oil stains and even chemical agents; the long-term unavoidable tread wear and even scratching and peeling can occur. In the daily operation of the rail transit vehicle, the wheel set is abraded at a high speed due to frequent acceleration and deceleration, braking and the like. The wheel set is seriously worn, so that not only can wheel-rail noise be generated, the comfort of passengers be reduced, but also the performance and the running safety of a train are affected, and the life safety of the passengers is seriously threatened.

The signal processor can measure the distance between the sensor and the wheel tread according to the reflection angle and the distance between the laser spot and the photosensitive device. The 2D laser displacement sensor realizes linear scanning of a measured target by using linear laser and obtains the displacement of each point of the outline of the measured object. The geometric dimension of the wheel pair has important influence on the safe operation of the vehicle, and the precision requirement on the geometric parameter detection of the wheel pair is extremely high. The precision of a general 2D laser displacement sensor can be completely met, but the precision is limited by the complex influence of the civil construction environment of the ballast bed, and the high precision requirement is provided for the installation of the laser displacement sensor. Therefore, the realization of the multi-degree-of-freedom installation of the 2D laser displacement sensor has important significance.

When the track bed is used, the embedded bottom plate 1 is embedded in the track bed in advance, and the embedded bottom plate 1 is provided with a first locking threaded hole 11.
As shown in fig. 2, which is a schematic view of the leveling base plate 2, the leveling base plate 2 is provided with a first kidney-shaped hole 20, a leveling threaded hole 21 and a second locking threaded hole 22.
In this embodiment, four first kidney-shaped holes 20 and four leveling threaded holes 21 are symmetrically disposed on the leveling base plate 2.
Each leveling threaded hole 21 is provided with a leveling screw 23, the lower end of which is supported on the surface of the embedded bottom plate 1, and the leveling screw is used for adjusting the posture of the leveling bottom plate 2 relative to the embedded bottom plate 1.
The origin of the XOY coordinate system shown in fig. 7 is located at the center of the leveling base plate 2, the Z-axis coincides with the central axis of the leveling base plate 2, and the attitude adjustment includes translation along the Z-axis shown in fig. 7, rotation around the X-axis shown in fig. 7, and rotation around the Y-axis shown in fig. 7.
Z-axis translation adjustment: the four leveling screws 23 move axially for the same distance along the Z axis relative to the leveling base plate 2, and in the adjusting process, the first locking screws 24 need to be matched with the leveling base plate, and the operation of not obstructing the movement of the leveling base plate 2 needs to be carried out, so that the leveling base plate is completely locked after the adjustment is completed.
Rotation adjustment around the Z axis: the first locking screw 24 is loosened, so that the head of the first locking screw 24 is not pressed against the countersunk head part of the first kidney-shaped hole 20, and because a horizontal adjusting gap is formed between the first locking screw 24 and the first kidney-shaped hole 20 (including the adjusting gap between the head of the first locking screw 24 and the side wall of the countersunk head section of the first kidney-shaped hole 20 and the adjusting gap between the rod part of the first locking screw 24 and the side wall of the screw rod part penetrating section of the first kidney-shaped hole 20), the adjusting bottom plate 2 can be directly rotated around the Z axis at the moment, and then the first locking screw 24 is locked.
Rotational adjustment about the X axis: due to the horizontal adjusting clearance between the first locking screw 24 and the first kidney-shaped hole 20, the rotation adjustment around the X axis can be realized, the adjusting angle is small, generally several degrees, specifically, the left pair of leveling screws 23 is moved by the same distance along the Z axis relative to the leveling base plate 2, while the right pair of leveling screws 23 is kept stationary relative to the leveling base plate 2, or the right pair of leveling screws 23 is moved by the same distance axially along the Z axis relative to the leveling base plate 2, while the left pair of leveling screws 23 is kept stationary relative to the leveling base plate 2.
Rotational adjustment about the Y axis: due to the adjustment clearance in the horizontal direction between the first locking screw 24 and the first kidney-shaped hole 20, a rotational adjustment around the X-axis can be achieved, which is small, typically a few degrees, in particular by moving the front pair of leveling screws 23 axially with respect to the leveling base plate 2 along the Z-axis by the same distance while the rear pair of leveling screws 23 remains stationary with respect to the leveling base plate 2, or by moving the rear pair of leveling screws 23 axially with respect to the leveling base plate 2 along the Z-axis by the same distance while the front pair of leveling screws 23 remains stationary with respect to the leveling base plate 2.
In the rotation adjustment around the X axis and the rotation adjustment around the Z axis, the first locking screw 24 is required to be matched, and the first locking screw 24 is required to perform an operation of not obstructing the movement of the leveling base plate 2, and is completely locked after the adjustment is completed.

In order to further ensure that the first locking screw 24 does not obstruct the posture adjustment of the leveling base plate 2 when the posture of the leveling base plate 2 is adjusted, the top view structure of the first kidney-shaped hole 20 shown in fig. 3 is designed to have a slight bending arc, and the inner side of the bending arc faces to the center position of the leveling base plate, so that during the rotation adjustment process around the Z axis, the first locking screw 24 can relatively move along a bending track in the first kidney-shaped hole 20, and in combination with the adjustment gap in the horizontal direction between the first locking screw 24 and the first kidney-shaped hole 20, the obstruction of the adjustment process is less.
After the posture of the leveling base plate 2 is adjusted by the leveling screws 23, the leveling base plate 2 is completely fixed to the pre-buried base plate 1 by the first locking screws 24, that is, the lower ends of the first locking screws 24 are screwed to the first locking threaded holes 11 on the pre-buried base plate 1.
As shown in fig. 4, which is a schematic view of the lateral adjustment base plate 3, the lateral adjustment base plate 3 is provided with a second kidney-shaped hole 30 and a third locking screw hole 31.
In this embodiment, each second kidney-shaped hole 30 is equipped with a second locking screw 32, and the head of the second locking screw 32 is clamped on the top surface of the lateral adjustment base plate 3. The major diameter of the second kidney shaped aperture 30 is parallel to the Y axis. The second locking threaded holes 22 on the leveling base plate 2 are located below the second kidney-shaped holes 30 and are arranged in a row along the Y-axis.
By moving the transverse adjusting base plate 3 transversely along the Y axis, the lower ends of the second locking screws 32 are correspondingly screwed into the second locking threaded holes 22 at the corresponding positions below, so that the translational adjustment of the leveling base plate 2 along the Y axis is realized.
