Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

Examples

Referring to fig. 1 to 3, a walking device of a multifunctional support vehicle is mounted on a beam 1, and includes two rollers 2, a mandrel 3 and a beam circular plate 4, the rollers 2 and the beam circular plate 4 are sleeved on the mandrel 3, the rollers 2 are rotatably connected with the mandrel 3, outer bearings 5 are disposed on two sides of the rollers 2, the beam circular plates 4 are respectively disposed on two sides of the rollers 2, a gap 10 is formed between the outer bearings 5 on one side or two sides of the rollers 2 and the beam circular plate 4, and an adjusting backing ring 6 is disposed in the gap 10.

The outer part of the beam round plate 4 is tightly sleeved with a sleeve 7, and the outer bearing 5 is positioned in the sleeve 7. The thickness of the adjusting backing ring 6 is matched with the width of the gap 10, when the adjusting backing ring is assembled, the beam circular plate 4 is fixed on the beam 1, the roller 2, the outer bearing 5 and the sleeve 7 are assembled, the adjusting backing ring 6 is installed in the assembly, the assembly and the beam 1 are installed through the fastening screw and the mandrel 3, the gap between the beam circular plate 4 and the outer bearing 5 can be effectively eliminated, the assembling precision is improved, and the walking device is ensured not to generate axial offset and abnormal sound in the rolling process on the rail.

Be equipped with self-aligning roller bearing 8 between gyro wheel 2 and the dabber 3, gyro wheel 2 rotates continuously with dabber 3 through self-aligning roller bearing 8. The outer diameter of the beam circular plate 4, the outer diameter of the outer bearing 5 and the inner diameter of the sleeve 7 are matched. The outer diameter of the beam circular plate 4 of the existing walking device is not matched with the outer diameter of the outer bearing 5, so that the arrangement of the sleeve 7 is not facilitated, and in addition, only a common shaft sleeve 9 is generally arranged between the roller 2 and the mandrel 3 of the existing walking device, so that the adaptability of the walking device is lower than that of the self-aligning roller bearing 8 under the conditions of heavy load and impact load of a multifunctional support vehicle.
