Abstract

The invention relates to an amplitude and frequency regulating device. The output end of a first driving mechanism is connected with a first transmission shaft which is connected with a frequency regulating mechanism. The frequency regulating mechanism is fixedly connected with a shock excitation box and used for regulating the vibrating frequency of a road roller. An amplitude regulating mechanism comprises an amplitude regulating motor, the output end of the amplitude regulating motor is connected with an amplitude regulating driving gear which is engaged with an amplitude regulating driven gear, and the amplitude regulating driven gear is fixedly connected with the shock excitation box and drives the shock excitation box to rotate to regulate the phase between eccentric shafts. The frequency regulating mechanism rotates along with the first driving mechanism to change the vibrating frequency of a steel wheel, the output end of the motor of the amplitude regulating mechanism is provided with the amplitude regulating driving gear which is engaged with the amplitude regulating driven gear, and the amplitude regulating driven gear is fixedly connected with the shock excitation box and can drive the shock excitation box to rotate; and the frequency regulating mechanism is fixedly connected with the shock excitation box so that the frequency regulating mechanism can be rotated reversely when the shock excitation box rotates, and therefore the phase between the eccentric shafts is regulated.

Description

Technical field [0001] The invention relates to the technical field of road rollers, in particular to an amplitude and frequency modulation device and a road roller with the device. Background technique [0002] Vibratory roller is one of the important equipment in engineering construction. It is used to compact various soils, gravel materials, various asphalt concretes, etc. In highway construction, it is mostly used in the compaction of subgrade and pavement, and it is indispensable in road construction. Compaction equipment. Among them, the vibrating wheel is the core working mechanism of the vibratory roller. In the initial stage of road compaction, when the vibrating wheel is in contact with the material to be pressed, it gives strong and repeated impacts to the material to be pressed, so that the material to be pressed will vibrate and compact, and the loose road material will be gathered in a short time. To increase the material density, a larger vertical excitation forc...
