A filling compaction device

Abstract

The invention discloses a fill compacting device which comprises a road roller body. A vibration wheel is arranged on the rear side of the bottom of the road roller body. Multiple caterpillar band devices are arranged on the front side of the bottom of the road roller body. Each caterpillar band device comprises a driving gear, a first driven gear and a second driven gear, all of which are triangularly arranged. The outer sides of each driving gear, the corresponding first driven gear and the corresponding second driven gear are provided with a caterpillar band engaged with the driving gear, the first driven gear and the second driven gear. Caterpillar band rotary shafts are arranged at the centers of the caterpillar band devices. Center shafts of each driving gear, the corresponding first driven gear and the corresponding second driven gear are connected with the corresponding caterpillar band rotary shaft through connecting rods. The center shaft of each driving gear is provided with a hydraulic motor. The two ends of each caterpillar band rotary shaft are connected to the road roller body through caterpillar band hydraulic cylinders and self-locking hydraulic cylinders. Each self-locking hydraulic cylinder is connected with a steering device. By the adoption of the fill compacting device, a road roller can rotate by 360 degrees around the mass center of a steel wheel, so that the problem about the turning radius of an existing road roller is greatly solved.

Description

technical field [0001] The invention belongs to the technical field of road machinery, and in particular relates to a filling compaction device. 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. Single-drum vibratory rollers are also widely used in various engineering operations. Most of the current single-drum rollers are tire-type, which often makes them unable to be effectively used in harsh environments. (For example, when the roller is compacting on a gravel road, the undulation of the tire is not conducive to compaction. When compacting on a muddy road, the tire is easy to fall into the swamp.) The limitation of the turnin...
