Disclosure of Invention
The utility model aims to solve the problems of the conventional riding wheel device and provides a riding wheel device.
The specific scheme of the utility model is as follows: the utility model provides a riding wheel device, the on-line screen storage device comprises a base, two riding wheels are equipped with along length direction in the base upper end, the riding wheel axle is equipped with in the middle of the riding wheel, correspond every riding wheel department bilateral symmetry on the base and be equipped with a pair of bearing frame, be equipped with the bearing between riding wheel axle both ends and the bearing frame, it is equipped with a set of fixed establishment to lie in every bearing frame department on the base, fixed establishment is connected to form by first and lower half, lower half and base fixed connection, first is passed through the bolt and is connected with the lower half, form the bearing frame mounting hole between first and the lower half.
The lower half part and the base are welded.
The upper half part and the lower half part of the fixing mechanism are both semicircular annular plates, the two semicircular annular plates are butted to form the bearing seat mounting holes, and the bearing seat mounting holes corresponding to each pair of bearing seats are positioned on the same axis.
The bearing seat comprises a cylinder, the inner wall of the cylinder is connected with a bearing, a sealing cover is arranged at the outer end of the cylinder, an annular plate is arranged at the inner end of the cylinder, a sealing ring is arranged on the inner ring of the annular plate and is rotatably connected with a riding wheel shaft, and lubricating oil is filled in the cylinder.
The field installation operation of the utility model is as follows: the riding wheel, the riding wheel shaft and the bearings and the bearing seats at the two ends of the riding wheel shaft are installed in advance, after the base is fixedly installed on site, the riding wheel assembly is directly installed in the lower half part of the fixing mechanism, and after the riding wheel assembly is adjusted, the upper half part is connected with the lower half part.
The utility model has the following beneficial effects: 1. because the lower half part of the fixing mechanism and the base are integrated into a whole, the contact part of the lower half part and the bearing seat is subjected to finish machining, the parallelism, the axial distance, the radial distance and the like of the four bearing seats can be ensured to meet the precision requirement, the precision requirement is avoided being met in a field installation and debugging mode, the installation difficulty is reduced, and the cost of replacing spare parts at the later stage is reduced; 2. the diameter of the idler shaft is reduced, the length is shortened, and the weight and the overall dimension of the bearing seat are reduced.
