The utility model is applied to wheel set detection, and can realize the detection of defects such as scratch, stripping, gouge, out-of-roundness and the like on the wheel set. Before use, the vibration damping spring plate 2 needs to be assembled on the detection rod 1, and this embodiment is realized by plugging, and in some embodiments, in order to ensure plugging stability, further limiting is performed by pins, screws, bolts or fixing pieces thereof generally after plugging is completed.
In this embodiment, the insertion guiding structure 3 is a chute formed in the damping elastic sheet 2, and correspondingly, the detecting rod 1 has a protruding strip matched with the chute, so that the installation requirement of the detecting rod 1 can be well met through the mutually matched chute and protruding strip.
For better use of the present embodiment, the damping spring 2 includes a first mounting portion 4, and the first mounting portion 4 is disposed in a direction in which the movement is coming; the plug guiding structure 3 is arranged on the first installation part 4.
In this embodiment, the first mounting portion 4 has a chute provided along the movement direction, so that the first mounting portion 4 can be used to mount the damper elastic piece 2 into the detection lever 1. In this embodiment, the damping spring 2 has a hammering part 5, and the first mounting part 4 can be conveniently connected to the detecting rod 1 by striking the hammering part 5.
In this embodiment, the hammering portion 5 may be located below the damping spring 2 or may be located at two sides of the damping spring 2.
It is known that the size of the connection position between the detecting rod 1 and the first mounting portion 4 should be matched with the size of the first mounting portion 4, that is, after the detecting rod and the first mounting portion are matched, a gap between the detecting rod and the first mounting portion can be eliminated, so that vibration generated when a wheel passes through can be reduced.
It is of course also known that the upper surface of the first mounting part 4 should be flush with the detection surface of the detection rod 1, thereby avoiding wheel runout at the junction of the two.
For better use of the present embodiment, the damping spring further includes an elastic deformation portion 6, and the elastic deformation portion 6 is connected to the detection rod 1 through the first mounting portion 4.
In this embodiment, the wheel passes through the elastic deformation portion 6 and then transits from the upper surface of the first mounting portion 4 to the detection surface of the detection rod 1, when the wheel is located at the elastic deformation portion 6, the detection rod 1 is in a state of ready detection, and when the wheel is located at the detection rod 1, the detection rod 1 is pressed down at this time due to the degree of freedom of the detection rod 1 in the up-down direction, so that detection is achieved, and of course, the detection rod 1 should always be kept in contact with the wheel during this process.
Specifically, the elastic deformation portion 6 includes an introduction surface section 7 disposed obliquely along the movement, and the introduction surface section 7 is connected to the detection lever 1 through the first mounting portion 4.
In the present exemplary embodiment, the insertion surface section 7 is arranged obliquely to the detection surface of the detection rod 1. That is, the wheel contacts the lead-in surface section 7, deforms the elastically deforming portion 6, and then moves to the detection surface.
In this embodiment, the elastically deformable portion 6 further comprises a lead-out surface section 8 parallel to the movement direction and engaged with the lead-in surface section 7; the guide-out surface section 8 is connected with and flush with the detection surface of the detection rod 1.
The leading-out surface section 8 is in the same plane as the detection surface. After passing through the lead-in surface section 7, the wheel is transited to the detection surface through the lead-out surface section 8, so that the wheel is prevented from jumping when transiting between the lead-in surface section 7 and the detection surface.
In this way, in the mounted state, the upper surface of the elastic deformation portion 6 smoothly transitions to the detection surface of the detection lever 1 via the upper surface of the first mounting portion 4. That is, the wheel smoothly transits to the detection rod 1 through the leading-in surface section 7, the leading-out surface section 8, and the first mounting section 4 in this order.

The two end points of the long diameter are respectively an upper end point and a lower end point. Under some conditions of use, the elastic deformation portion 6 is in an initial state, the rod-shaped member contacts with the lower end point, a gap is also formed between the rod-shaped member and the lower end point, when the wheel contacts with the leading-in surface section 7, the elastic deformation portion 6 deforms, in the process that the wheel continuously displaces, the position of the rod-shaped member is gradually changed to the position of the upper end point at the lower end point, namely, the elastic deformation portion 6 continuously deforms or has a trend or action of recovering to the initial state, in the process that the elastic deformation portion 6 recovers to the initial state, the elastic deformation portion 6 is unloaded and sprung up, at this time, the rod-shaped member contacts with the lower end point, and the lower end point limits the elastic deformation portion 6 to continuously move towards one side of the detection surface far away from the first limit position 9, so that the elastic limit portion is prevented from tilting upwards relative to the initial state and rigidly colliding with the rear wheel. It is understood that the upper end point can limit the continuous deformation of the elastic deformation portion 6. Therefore, on the premise of eliminating potential safety hazards, the service life of the detection device is guaranteed, and the accuracy of the detection precision and the stability of the detection process are also guaranteed.

The long groove 14 can set the sliding rail on the inner side of the detecting rod 1, thereby reducing the installation volume of the whole assembly and realizing miniaturization.
In this embodiment, the detection rod 1 is provided with a sensing panel 15.
It is known that the defect detection of the tread of the wheel in this embodiment is determined by the movement of the detecting rod 1, and the movement of the detecting rod 1 is vertical movement in the up-down direction, so in this embodiment, the detecting sensor is provided on the base, the sensing panel 15 is provided on the detecting rod 1, and the defect of the tread of the wheel can be realized by feeding back the position change of the sensing panel 15 through the detecting sensor.
