Double-driving type pavement construction road roller

Abstract

The invention discloses a double-driving type pavement construction road roller which comprises a basic vehicle head, active driving wheels and a road rolling device, wherein the active driving wheels are arranged at the lower end of the basic vehicle head; the road rolling device consists of a basic rectangular frame, a rolling shaft, a grinding wheel, a lifting device, a second driving device and a cleaning device; the lifting device consists of a hollow telescopic support column, a vertical wheel, a lifting cylinder, a support block and a high-pressure spring; the second driving device consists of a rectangular support rack, a driving gear, a rotating shaft I, a driven pulley, a driving pulley, a belt and a driving motor I; the cleaning device consists of a concave bracket, a fixing bearing I, a rotating shaft II, a brush fixing ring, a brush and a driving motor II; a water storage tank is arranged at the rear end of the basic vehicle head; the water storage tank is communicated with the inner cavity of the concave bracket through a water inlet tube; a safety chair, a storage battery, a control tank, an operation panel and a power supply switch are arranged inside the basic vehicle head. The double-driving type pavement construction road roller has the beneficial effects of being simple in structure and good in practicability.

Description

technical field [0001] The invention relates to the field of engineering construction equipment, in particular to a dual-drive road construction 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, The roadbed is stabilized with soil and asphalt concrete pavement, but the rollers of existing road rollers are driven by constant friction, mainly relying on the power supplied by the rear end of the roller to rotate the rollers, which not only increases the burden on the car body but also reduces the efficiency of rolling At the same time, during the rolling process of the roller, some soil will adhere to its surface, and the effect of rolling will be reduced if it is not cleaned in t...

[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, The roadbed is stabilized with soil and asphalt concrete pavement, but the rollers of existing road rollers are driven by constant friction, mainly relying on the power supplied by the rear end of the roller to rotate the rollers, which not only increases the burden on the car body but also reduces the efficiency of rolling At the same time, during the rolling process of the roller, some soil will adhere to its surface, and the effect of rolling will be reduced if it is not cleaned in time. Moreover, when the roller is not in use, the roller is placed on the road and rolled, which will also cause certain damage to the surface. Therefore, a dual-drive road construction road roller is needed now, and a second drive device is provided on the basis of the driving force of the traditional road roller, which not only reduces the burden on the car body but also The efficiency of rolling is increased, and at the same time, the surface of the roller is cleaned from time to time during the operation of the roller. It can also be sprayed with some water to reduce the adhesion of the surface of the roller to the road soil. When not in use, it can be The roller is kept at a certain distance from the ground through the lifting device, and the distance sensor is equipped to prevent the road roller from accidentally damaging the facilities on both sides of the road
