[0022] The working principle is as follows: the embodiment moves on the track, is limitedly installed on the rail through the roller support part 16 and the roller end part 17, the position of the roller end part 17 can be adjusted, that is, adaptive adjustment is made according to the rail width, in addition, after a period of movement, the roller end part 17 is worn due to long-time friction with the track, therefore, the position of the roller end part 17 can be adjusted according to the wear degree, specifically, the gear three 20 is rotated through the work of the motor two 19, then the screw rod three 21 and the gear three 20 are rotated, so that the roller end part 17 at both ends of the roller support part 16 moves, and the position adjustment is completed, at the same time, the traveling frame 15 is synchronously moved through the control of the cylinder three 14, so as to adapt to the position change of the roller end part 17.

[0023] When the contact surface of the roller end part 17 and the track is checked, the position of the detection mounting frame 11 is controlled through the cylinder one 10, the cylinder two 12 controls the contact between the detection contact shaft 13 and the inner side end surface of the roller end part 17, and the displacement sensor is used for outputting the feedback telescopic signal of the detection contact shaft 13, so as to check the distance between the two roller end parts 17.

[0024] Further, when moving, the motor one 7 works, the sweeper 8 rotates, and the sundries on the track can be swept; and when moving, the angle detector 2 can output the angle information of the rotating shaft 5, for example, when the angle of the track changes, the roller support part 16 and the roller end part 17 move along the path of the track, and when the angle region is present, the rotating shaft 5 changes the angle, so that the whole traveling track can be recorded and analyzed.

[0025] Further, when moving, the sliding seat 4 can adapt to slight changes in track spacing, that is, the sliding seat 4 can move on the mounting base 1; in a sloping section, for example, at a curve, the outer track is higher than the inner track in terms of geographical position, that is, the outer track is high, which can offset the centrifugal force generated when the train turns, so that the center of gravity of the train is more stable; in this section, the inclination angle can be measured, at this time, the center of gravity of the suspension sphere 41 deviates, extrudes the outer side of each deflection contact rod 45, and then the spring 46 is compressed, the pressure detector outputs a feedback pressure signal, and the single or multiple deflection contact rods 45 are extruded. The greater the inclination angle, the greater the force on the deflection contact rod 45, and the inclination angle of the suspension sphere 41 can be analyzed according to the principle of mechanics. It should be noted that the process needs to be slow, and the to-be-measured point can be marked. Stop moving at the to-be-measured point, and after the suspension sphere 41 is stable, data analysis and recording are performed. The above measurement process can also be applied to the ramp area.

[0026] Further, for the deflection of the suspension sphere 41, it is necessary to ensure that it has the lubrication performance of deflection, therefore, the spherical surface area between the contact sphere 40 and the spherical surface connecting portion 44 needs to be regularly replaced with lubricating oil. Specifically, in order to facilitate replacement and detection, the gear ring 37 is rotated by controlling the motor 38 to work, and then the lead screw 42 is moved, so that the spherical surface connecting portion 44 is separated. Before this, the suspension sphere 41 and the contact sphere 40 need to be restored to the original position, that is, the axis coincides with the axis of the mounting cylinder 3. The angle disc 32 is rotated by controlling the angle motor 31, the height of the reset frame 35 is controlled by the reset cylinder one 33, and the reset frame 35 is controlled to move radially by the reset cylinder two 34, so as to push the deflection contact rod 45 to reset, and then the suspension sphere 41 is reset. The clamping cylinder 29 is matched with the top of the contact sphere 40 by controlling the transfer cylinder 22, and the electromagnetic sliding clamp plate 30 clamps the top of the contact sphere 40, and then the contact sphere 40 and the suspension sphere 41 are transferred.

[0027] The operator can clean the surface of the contact sphere 40 and the inner side of the spherical surface area of the spherical surface connecting portion 44, that is, remove the dirty oil, and then apply new lubricating oil. The inspection cylinder two 27 is moved by controlling the inspection cylinder one 26, the ultrasonic device is moved to the inner side of the spherical surface connecting portion 44 by controlling the inspection cylinder two 27, the inspection turntable 25 is rotated by controlling the motor four 23, the surface of the inner side of the spherical surface area of the spherical surface connecting portion 44 is detected, the surface of the contact sphere 40 is detected by controlling the inspection cylinder three 28, so as to ensure that the contact sphere 40 and the spherical surface connecting portion 44 can move smoothly, and ensure that the suspension sphere 41 can deviate smoothly.
