When the rotating rod 13 rotates, the inner spline sleeve 17 on the rotating rod 13 rotates, and the transmission wheel 16 on the inner spline sleeve 17 rotates synchronously with the inner spline. A transmission mechanism for synchronous rotation of the transmission wheel 16 and the belt wheel 28 is provided between the transmission wheel 16 and the belt wheel 28. An adjustment component for moving the inner spline sleeve 17 along the spline shaft 14 is provided inside the hollow shell 1.

[0075] A connecting plate 29 is fixed to an outer spline sleeve 31. A straight slot is provided on the outer side of the connecting plate 29. A cylinder 30 is slidably provided inside the straight slot. One end of the cylinder 30 is rotatably installed at a non-axial position of the belt wheel 28. When the belt wheel 28 rotates, the cylinder 30 at the non-axial position of the belt wheel 28 rotates with the belt wheel 28. The cylinder 30 on the belt wheel 28 drives the connecting plate 29 to reciprocate and telescopically move through the straight slot.

[0076] Specifically, the transmission mechanism includes:

[0077] Cone 21, two fourth fixing plates 20 are fixed inside the hollow shell 1, two ends of the cone 21 are rotatably mounted on the two fourth fixing plates 20, and the generatrix of the cone 21 is parallel to the central axis of the rotating rod 13, and the transmission wheel 16 is in contact with the cone 21; the transmission wheel 16 and the cone 21 form a stepless transmission mechanism, and when the transmission wheel 16 moves to a certain position, the rotation speed of the cone 21 changes accordingly;

[0078] The universal shaft 26 has two ends coaxially fixed with the cone 21 and the shaft wheel 28 respectively. The cone 21 drives the shaft wheel 28 to rotate through the universal shaft 26. When the speed of the cone 21 changes, the shaft wheel 28 also changes accordingly, so that the reciprocating expansion and contraction frequency of the outer spline sleeve 31 changes. For example, the detection point is changed from 2ΔX to ΔX. At this time, the reciprocating expansion and contraction frequency of the outer spline sleeve 31 increases accordingly to ensure that the vibration sensor 3 can fit the structural column at the ΔX position.

[0079] Specifically, the adjustment components include:

[0080] The first servo motor 18 is a prior art, and its specific structure and working principle are not described in detail here. The shell of the first servo motor 18 is fixed on the hollow shell 1;

The outer side of the second fixed plate 15 is sleeved on the single threaded rod through a thread. When the single threaded rod rotates, the single threaded rod drives the third fixed plate 19 to move through the threaded transmission.

[0084] Working principle:

[0085] The hollow shell 1 is fitted with the structural column, and two clamping plates 2 are placed on both sides of the structural column. The worker rotates the double-threaded rod 6, and the two ends of the double-threaded rod 6 drive the internal threaded sleeve 11 to move through the form of thread transmission. Since the internal threaded sleeve 11 is fixed to the clamping plate 2, the internal threaded sleeve 11 drives the clamping plate 2 to move, and the clamping plate 2 approaches the structural column until the clamping wheel 9 on the clamping plate 2 contacts the structure.

[0086] The second servo motor 22 rotates the worm 24 through the output shaft. When the worm 24 rotates, the worm 24 moves the rotating rod 13 through the worm wheel 23 meshing with it, and the two contact wheels 12 on the rotating rod 13 rotate accordingly. Since the contact wheels 12 are in contact with the moving roller 10, the contact wheels 12 drive the moving roller 10 to rotate through friction.

[0087] When the rotating rod 13 rotates, the inner spline sleeve 17 on the rotating rod 13 rotates, and the transmission wheel 16 on the inner spline sleeve 17 rotates synchronously with the inner spline. The transmission wheel 16 moves the cone 21 through friction, and the cone 21 drives the belt shaft wheel 28 to rotate through the universal shaft 26. When the belt shaft wheel 28 rotates, the cylinder 30 at the non-axial position of the belt shaft wheel 28 rotates with the belt shaft wheel 28, and the cylinder 30 on the belt shaft wheel 28 drives the connecting plate 29 to reciprocate and telescopically move through the straight notch.

[0088] The first servo motor 18 rotates the single-threaded rod through the output shaft. When the single-threaded rod rotates, the single-threaded rod drives the third fixed plate 19 to move through the threaded transmission. The transmission wheel 16 and the cone 21 form a stepless transmission mechanism. The transmission wheel 16 moves to a certain position, and the rotation speed of the cone 21 changes accordingly. When the speed of the cone 21 changes, the shaft wheel 28 also changes accordingly, so that the reciprocating expansion and contraction frequency of the external spline sleeve 31 changes. For example, the detection point is changed from 2ΔX to ΔX. At this time, the reciprocating expansion and contraction frequency of the external spline sleeve 31 increases accordingly to ensure that the vibration sensor 3 can fit the structural column at the ΔX position.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
