Supporting wheel device used for cabling machine

The invention discloses a supporting wheel device used for a cabling machine. The supporting wheel device comprises a chassis and two set of supporting wheel assemblies arranged on the chassis; each supporting wheel assembly comprises two supporting seats which are fixed on the chassis and a supporting wheel arranged between the two supporting seats; each supporting wheel sleeves a rotating shaft through a bearing; the rotating shaft is provided with penetrating covers which are located at two sides of the bearing; two ends of the rotating shaft respectively extend out from corresponding supporting seats; through holes are formed in portions of the rotating shaft which extend out from the supporting seats; the rotating shaft is provided with two fixing planes which are located at two ends of the through holes; through holes at the same side of the rotating shaft of each set of supporting wheel assembly are connected with each other through a connecting rod; and two ends of the connecting rod are respectively provided with a screw thread. According to the supporting wheel device of the invention, through the effect of the connecting rod, one set of supporting wheel assembly can be adjusted, and thereafter, the other set of supporting wheel assembly can be pulled to the center through the connecting rod until acting forces at two sides of the connecting rod are balanced, and contact surfaces are fittingly attached to each other, and therefore, labor intensity of installation personnel can be reduced, time and labor can be saved; and after installation, operational stability of equipment is higher, and noises are low, and the bearing strength of the installed supporting wheels is larger.
