Referring to fig. 1 and 5, during detection, the fourth extensible member 420 extends out to drive the rotating rod 440 to rotate and the mounting frame 430 to move toward the direction of the wheel 02, so that the transverse driving wheel 460 abuts against one side surface of the wheel 02, in this embodiment, the transverse driving wheel 460 abuts against the side surface of the wheel 02 far away from the bearing 03, the second driving member 450 drives the transverse driving wheel 460 to rotate, so as to drive the wheel 02 to rotate, and after detection, the fourth extensible member 420 retracts to no longer provide rotating power for the wheel 02.
Further, in one embodiment, the wheel driving mechanism 40 further includes a speed reducer 470, and the second driving member 450 is connected to the transverse driving wheel 460 through the speed reducer 470. Since the wheel 02 is kept at a low speed during the detection of the wheel 02, the rotation speed of the transverse driving wheel 460 is reduced by the speed reducer 470, so as to meet the detection requirement.
The mounting structure for detection mainly provides external pressure loading for a wheel 02 and a bearing 03 of a railway wagon, the wheel 02 rotates, and the bearing 03 rotates. The rotating speed of the wheel 02 can be kept at 8rpm, the rotating speed of the bearing 03 can be switched between 80 rpm and 600rpm, and the loading pressure of the wheel 02 can reach 7 tons.

When the bearing 03 rotates, the vibration sensor can obtain the vibration performance of the bearing 03 by analyzing the vibration data of the bearing 03.
According to the bearing and wheel detection equipment, after the wheel 02 reaches the position to be detected, the wheel mounting mechanism 20 is triggered, the wheel 02 is pushed to the detection station, the wheel mounting mechanism 20 descends to act, and the wheel 02 falls. The bearing 03 drops into the bearing support mechanism 10, and the loading mechanism 30 drops and presses the upper portion of the axle 01. The wheel driving mechanism 40 operates to drive the wheels 02 to rotate at a slow speed, after the rotation of the wheels 02 stops, the bearing supporting mechanism 10 operates to rotate at a high speed to drive the bearings 03 to rotate, and after the detection is finished, the loading mechanism 30 is removed. The wheel mounting mechanism 20 drives the wheel 02 to rise and pushes the wheel 02, so that the piece to be detected is pushed out of the detection station, and the detection procedure is completed. The bearing and the wheel detection equipment are integrated with the rotation working condition of the wheel 02 and the bearing 03, so that the detection environment can be provided for the wheel 02 and the bearing 03 respectively, the detection of the wheel 02 and the bearing 03 can be realized through one-time installation, and the detection efficiency can be greatly improved. Through the cooperation of the loading mechanism 30 and the bearing supporting mechanism 10, the stability of the axle 01 center can be effectively ensured in the operation process, the process of measuring the size of the wheel 02 is facilitated, the pressure is loaded on the wheel 02 in the rotation process, the inner fault of the bearing 03 can be excited by rotating the outer ring of the bearing 03 at a high speed, the working condition environment of the wheel 02 and the bearing 03 during working can be simulated more truly, and the detection result is more accurate.
The mounting structure for detection in any of the above embodiments can be applied to detection of the wheel 02 and the bearing 03 of a motor vehicle such as a railway wagon and a highway wagon.
