AI Technical Summary

Technical Problem

The weight of the rollers of traditional rollers is too large, resulting in increased energy consumption, excessive loading of the transmission system and tire components, and limited vibration function and eccentric amplitude adjustment capabilities, which cannot meet the compaction needs of different road surfaces.

Method used

The composite structure of the inner cylinder, the support bone and the outer cylinder is adopted. The inner cylinder adopts a high-strength fiber-reinforced resin-based composite material. The outer cylinder is an wear-resistant metal-based composite material. The support bone serves as an intermediate force transmission layer. It is combined with the cylinder pushing adjustment block to adjust the eccentric amplitude to achieve flexible adjustment of the eccentric amplitude.

Benefits of technology

It reduces the weight of the roller, reduces energy consumption, extends the service life of the equipment, improves the applicability and construction quality of the roller, and can flexibly adjust the vibration frequency and eccentricity according to different road surface needs.

Abstract

The present invention discloses a road roller lightweight composite roller structure, and relates to the technical field of road rollers, the road roller lightweight composite roller structure comprises a main body mechanism, the main body mechanism comprises a main shaft, the end portion of the main shaft is fixedly connected with a connection flange, and the surface of the end portion of the main shaft is rotatably connected with a mounting member; and the vibration mechanism comprises a fixing piece, and the top of the fixing piece is fixedly connected with a motor. Through a combined structure of the inner barrel, the supporting ribs and the outer barrel in the main body mechanism and the special design that the diameters of the two ends of the supporting ribs are larger than those of the middles, the structural strength is guaranteed, meanwhile, unnecessary material use is reduced, the overall weight of the roller is reduced, and the light-weight roller can effectively reduce energy consumption during equipment operation and improve the production efficiency. The load on a transmission system, tires and other parts is reduced, the service life of equipment is prolonged, meanwhile, the air cylinder pushes the pushing piece, then the adjusting block is driven to slide on the sliding rail, the adjusting block is connected with the balancing weight through the supporting rod, and therefore the position of the balancing weight is adjusted.
