Abstract

The invention discloses a stepless amplitude adjusting and vibration exciting device for a road roller. A vibration exciting mechanism in an inner cylinder of a vibration wheel comprises a first vibration exciter and a second vibration exciter which are the same in structure, and the first vibration exciter comprises a first vibration exciting shaft A, a first fixing transverse plate, a first hydraulic cylinder, a first vibration exciting shaft B, a first fixed step sliding cylinder and a second fixed step sliding cylinder; and except for the fixed parts, other parts of the first fixed step sliding cylinder and the second fixed step sliding cylinder can slide, a cavity q1 is constituted by the upper end face of the first fixed step sliding cylinder and the first hydraulic cylinder, a cavity w1 is constituted by the lower end face of the first fixed step sliding cylinder and the first fixing transverse plate, a cavity e1 is constituted by the upper end face of the second fixed step sliding cylinder and the first fixing transverse plate, and a cavity r1 is constituted by the second fixed step sliding cylinder and the first hydraulic cylinder. According to the stepless amplitude adjusting and vibration exciting device, stepless adjusting of the vibration amplitude of the vibrating road roller in the vertical vibration exciting mode and the horizontal vibration exciting mode can beachieved, meanwhile, the working efficiency of the vibrating road roller can be improved more effectively, and the using range of the vibrating road roller can be expanded more effectively.

Description

technical field [0001] The invention belongs to the technical field of road rollers, and more specifically relates to a stepless amplitude modulation excitation device for road rollers. Background technique [0002] Vibratory road rollers are one of the important equipment for engineering construction. They use their own gravity and vibration to compact various soils, crushed stones, various asphalt concrete, etc. In road construction, they are mostly used for compacting roadbeds and road surfaces. Indispensable compaction equipment in construction.

Problems solved by technology

The most convenient amplitude modulation mechanism before is achieved by superimposing the fixed rotor and the movable vibrator in different directions. The double-amplitude vibration can be realized only by changing the rotation direction of the hydraulic motor, and the relative angle between the fixed vibrator and the movable vibrator can be realized by adjusting the spline or scarfing. Multi-level amplitude switching, multi-level amplitude can only realize the conversion of several amplitudes and cannot meet all work needs. For this reason, it is necessary to design a stepless amplitude modulation excitation mechanism to realize stepless conversion of amplitude, and at the same time can realize vibration. Two modes of vertical excitation and horizontal excitation
