Road roller for bridge construction by means of double actions of gravity and magnetic force

Abstract

The invention discloses a road roller for bridge construction by means of double actions of gravity and a magnetic force. The road roller structurally comprises an equipment driving case, an oil storage box, a pavement pinch roller, a belt protecting hood, a supporting rack and a pushing handle. The road roller is combined with a gravity driving structure through a vibratory exhaust device. Beforea concrete pavement of a bridge is compacted, the vibratory exhaust device can discharge air bubbles in concrete quickly. Meanwhile, the concrete is extruded more compactly through the gravity driving structure, so that the density of the concrete of the bridge is increased, air gaps in the concrete of the pavement of the bridge are avoided, and the condition that the pavement collapses is avoided as vehicles travel on the pavement to extrude the pavement. The quality of bridge construction is improved effectively, and the service life of the bridge is prolonged.

Description

technical field [0001] The invention relates to the field of construction machinery equipment, in particular to a road roller for bridge construction that utilizes the dual effects of gravity and magnetism. Background technique [0002] With the reform and development, the city is developing rapidly. In order to meet the communication between different regions, shorten the traffic distance between the two sides of the river, and shorten the journey between the two places by building roads and bridges, road rollers are needed in the process of bridge construction. The cement pavement is compacted, but the current technical considerations are not perfect, and it has the following disadvantages: the existing road roller can only compact the road surface through the pressure roller, and the pressure roller generally squeezes the road surface by its own weight, and the road surface within a unit area is affected The pressure is the same, because the force on the road surface is t...

[0002] With the reform and development, the city is developing rapidly. In order to meet the communication between different regions, shorten the traffic distance between the two sides of the river, and shorten the journey between the two places by building roads and bridges, road rollers are needed in the process of bridge construction. The cement pavement is compacted, but the current technical considerations are not perfect, and it has the following disadvantages: the existing road roller can only compact the road surface through the pressure roller, and the pressure roller generally squeezes the road surface by its own weight, and the road surface within a unit area is affected The pressure is the same, because the force on the road surface is the same, resulting in the limited extrusion force of the pressure roller, which cannot fully squeeze out the air in the concrete, resulting in air gaps on the bridge road surface, and the road surface will be stuck after the vehicle is squeezed, and the quality of the bridge is relatively poor. Poor, shorten the service life of the bridge
