Abstract

The invention discloses a double-steel-wheel road roller. The double-steel-wheel road roller comprises a road roller main body, two steel wheels and a water tank for spraying water into the steel wheels, wherein a water outlet is formed in the water tank; a magnetic stopping block for blocking the water outlet is arranged above the water outlet; an electromagnet is arranged at one side of the magnetic stopping block; the other side of the magnetic stopping block is connected with an inner wall of the water tank through an elastic part; the steel wheels are provided with a power generator connected with the electromagnet. According to the double-steel-wheel road roller, the steel wheels rotate so that the power generator generates power; an attraction force generated by the electromagnet connected with the power generator attracts the magnetic stopping block, which stops the water outlet of the water tank, for moving so that water in the water tank flows onto the steel wheels through the water outlet; meanwhile, different electricity quantities are generated by the power generator according to different rotary speeds of the steel wheels, so that the electromagnet attracts the magnetic stopping block to move for different distances, and furthermore, variable-quantity water output of the water tank is realized; the double-steel-wheel road roller is very convenient.

Description

technical field

[0001] The invention belongs to the field of road engineering machinery and equipment, and in particular relates to a double-steel wheel road roller. Background technique

[0002] Road rollers belong to the category of road equipment in construction machinery. They are widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-cohesive and cohesive soils, Subgrade stabilized soil and asphalt concrete pavement layer. When rolling asphalt concrete pavement, due to the adhesiveness of asphalt, it is necessary to spray water on the steel wheel to form a water film on the steel wheel to prevent the asphalt concrete from adhering to the steel wheel, which will cause the road surface to be not smooth due to the adhesive material during rolling. smooth. However, the existing technology cannot discharge water according to the variable s...
