The amount of pressure the rail exerts on the rail steel pipe 31 reflects the distance information between the rail and the rail offset width sensor 50. The greater the pressure exerted by the rail on the steel contact rail tube 31 indicates the closer the distance between the rail and the rail offset width sensor 50; a smaller pressure exerted by the rail on the rail steel pipe 31 indicates a greater distance between the rail and the rail offset width sensor 50. After the pressure applied to the contact rail steel pipe 31 by the rail is detected by the pressure sensing box 32, the height of the mounting plate 10 is adjusted by the height adjusting mechanism 40 controlled by the central processing unit, so that the rail deviation width sensor 50 always works within a required distance range from the rail, the accuracy of rail position detection is ensured, and the safety and reliability of the transfer platform in-rail running are further improved.

The farther the proximity switch 326 is from the sensing block 324, the closer the track offset width sensor 50 is to the track; the closer the proximity switch 326 is to the sensing block 324, the further the track offset width sensor 50 is from the track.

acquiring pressure information applied to a vehicle body track on a profiling pressure detection device (30) through the profiling pressure detection device (30), and sending the pressure information to a central processing unit, wherein the central processing unit controls a height adjusting mechanism (40) to adjust the height of the mounting plate (10) according to the pressure information, so that the track deviation width sensor (50) and the track keep proper height;
the track deviation width sensor (50) detects the deviation position of the track relative to the track deviation width sensor (50) under the condition of keeping the horizontal position and the height suitable for the track so as to determine the width of the track deviated from the axis center of the crawler chassis of the vehicle body.
9. The track position detection method of the track integrated transfer platform of the track according to claim 8, wherein the step of obtaining pressure information applied to the profiling pressure detection device (30) by the vehicle track through the profiling pressure detection device (30) and sending the pressure information to the central processing unit, wherein the central processing unit controls the height adjustment mechanism (40) to adjust the height of the mounting plate (10) according to the pressure information comprises the steps of:
the state of the spring (33) is detected through the pressure sensing box (32), and when the spring (33) is in a relaxed state, the central processor controls the height adjusting mechanism (40) to act, so that the mounting plate (10) integrally descends until the rail contact steel pipe (31) presses the rail; when the spring (33) is in a stretching state, the height adjusting mechanism (40) stops acting; when the tension of the spring (33) in the stretching state exceeds a set value, the central processor controls the height adjusting mechanism (40) to act, so that the mounting plate (10) is integrally lifted.
10. The track position detection method of the track-integrated transfer platform according to claim 9, wherein the detecting the state of the spring (33) through the pressure sensing box (32) comprises:
when the spring (33) is in a stretching state, the contact rail steel pipe (31) is pressed on the track to roll, and the spring (33) drives the contact rotating shaft (322) in the pressure sensing box (32) to rotate outwards, so that the distance between the sensing block (324) in the pressure sensing box (32) and the proximity switch (326) is increased;
when the spring (33) is in a relaxed state, a return spring (325) in the pressure sensing box (32) drives the contact rotating shaft (322) to rotate inwards, so that the distance between the sensing block (324) and the proximity switch (326) is reduced;
the state of the spring (33) is detected by detecting the distance between the sensing block (324) and the proximity switch (326).
