Self-aerating and pressure-regulating device for rubber tire road roller

Abstract

The invention discloses a self-aerating and pressure-regulating device for a rubber tire road roller, which belongs to the field of aerating and pressure-regulating devices of rubber tire road rollers. The device comprises a front wheel assembly, a frame, a cab assembly, a power system, a back wheel assembly and an air channel system, wherein the air channel system comprises an air compressor, a pressure valve bank, an aerating valve bank, rotating valves, air tank assembly, pressure gauges, rubber tires, an electromagnetic reversing valve and a deflating valve bank; the air tank assembly is connected with one end of the pressure valve bank, one end of the aerating valve bank and one pressure gauge respectively; the other end of the pressure valve bank is connected with the air compressor; the other end of the aerating valve bank is connected with another pressure gauge, one end of each of a plurality of rotating valves and the deflating valve bank respectively; and the other end of each rotating valve is connected with the rubber tires through the electromagnetic reversing valve. The self-aerating and pressure-regulating device has the advantages that: the aerating way of the conventional rubber tire road roller is greatly improved, an automatic pressure-regulating device is arranged, the complex and dangerous situations caused by an original operation method are avoided, and the reliability and operating convenience are improved.

Description

technical field [0001] The invention relates to a self-inflating and pressure-regulating device of a rubber-tyred road roller, belonging to the technical field of inflating and pressure-regulating devices for a rubber-tyred road roller. Background technique [0002] The laying process of asphalt pavement is usually: first, pave the asphalt mixture with a paver, and then use a double-drum vibratory roller for initial pressure and re-pressure within a specified time, and finally use a rubber wheel roller for the second time. Twice the final compaction. The rubber-tyred road roller has an irreplaceable advantage. Its pneumatic tires have not only vertical compaction force, but also horizontal compaction force. The action of these forces plus a "kneading" effect produced by the elasticity of the rubber wheel forms a uniform, dense, The crack-free surface can prolong the service life of the pavement, thereby ensuring the quality of pavement construction. However, the tires of t...

AI Technical Summary

Problems solved by technology

However, the tires of traditional rubber-tyred road rollers are inflated by foreign objects, and the pressure cannot be adjusted independently. Under different road conditions, it will not only bring a lot of inconvenience to the operators, but also affect the construction quality and work efficiency.
