Abstract

The invention discloses a pedal foldable road roller for constructional engineering. The pedal foldable road roller for constructional engineering comprises a roller body, a front roller wheel and a rear roller wheel, wherein the front roller wheel and the rear roller wheel are arranged below the roller body and are identical in size. A handrail is arranged on the roller body. A sun shield is arranged on the roller body and located over the handrail. A pedal is arranged on the roller body and located under the handrail. A supporting wheel is arranged below the pedal. The length of the supporting wheel is identical to that of the rear roller wheel. The pedal comprises a connecting plate connected with the roller body and a supporting plate hinged to the connecting plate. The pedal foldable road roller for constructional engineering has the beneficial effects that the pedal is arranged under the handrail of the road roller and used for a driver to stand, the labor intensity is reduced, and the labor efficiency is improved; the supporting wheel is arranged below the pedal, so that the phenomenon that the pedal is broken due to the fact that the pedal supports the driver for a long time is avoided; and when the driver operates the road roller to make a turn, the pedal can be folded upwards, and the driver cannot be affected.

Description

technical field [0001] The invention relates to the field of construction, mainly a road roller, in particular to a road roller with retractable pedals for construction engineering. 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. [0003] When it comes to road rollers, I have to give a brief introduction to the development of compaction technology. As early as in ancient times, people used the hooves of herds to trample, knead and tamp the soil to deal with the foundation of houses and compact dams. And river embankments, before the middle of the 19th century, Western road engineering was mainly paved with gravel, and the comp...
